Definitions
- ABSTRACT A nozzle for cleaning the inside of piping, such as sewer lines and the like, receives high pressure water from a hose attached to the back thereof. The water is emitted from a front port or jet to dislodge debris clogging the pipe.
- the body of the nozzle is fluted thereby being divided into a series of vanes to permit the passage of loosened debris through the flutes and toward the rear of the nozzle.
- Each vane includes a plurality of thrust ports or jets mounted on a surface angular to the circumferential extremity of the nozzle and emitting water generally rearwardly to drive the nozzle and hose through the pipe.
- Each vane also includes a flusher port or jet which is mounted on a surface angular to both the circumferential extremity of the nozzle and the surface of the thrust port and which has an axis askew to the axis of the nozzle to create a volute flow of water to clear debris or sediment adher- 12 Claims, 7 Drawing Figures V PAIENIEIJJIJII um 3.8141330- v sum 20E 2,
- the invention relates to a nozzle for cleaning the interior of pipes and the like. More particularly this invention relates to a nozzle having a fluted body with a forward 'jet to dislodge material, rearward jets to render the nozzle self-propelled, and tangentially angled jets to dislodge materials which might adhere to the inside of the pipe, particularly a corrugated pipe.
- Nozzles emitting a forward stream of water to dislodge debris in pipes, such as sewer pipes, and emitting generally rearwardly directed streams to-propel themselves through the pipes are generally known in the art.
- these nozzles are mounted on the end of a hose and move through the pipe dislodging sediment until the limit of the hose has been reached. Then the nozzle is pulled back through the pipe with the rearwardly directed jets flushing the sludge toward the manhole or other means of access for subsequent removal.
- a generally cylindrical nozzle body is fluted or grooved at equally circumferentially spaced locations forming a plurality of axially extending vanes therebetween.
- the nozzle is attached to a hose at the back end thereof with the front end thereof being provided with aport which emits a stream of water substantially along the longitudinal axis of the nozzle to dislodge sediment in a pipe.
- the rear of each vane is provided with generally rearwardly directed thrust ports which have an axis rearwardly inclined at an acute angle to the axis of the nozzle body and which are mounted on a surface angular to the circumferential extremity of'the vanes.
- the thrust ports emit a stream of water to propel the nozzle through the pipe and to flush debris which passes through the flutes rearwardly.
- a plurality of sweeper ports are mounted on volute surfaces extending generally between the thrust port surfaces and the circumferential surface of the nozzle. The volute surfaces are angular to the thrust port surfaces and the circumferential surface of the nozzle with the sweeper port being on an axis askew to the longitudinal axis of the nozzle body.
- FIG. 1 is an elevational view of the nozzle of the present invention depicted in the operative environment of a laterally extending pipe such as a sewer, shown partially in section.
- FIG. 2 is an enlarged sectional view taken substantially along line 2-2 of FIG. 1 and showing the front of the nozzle of the present invention in elevation.
- FIG; 3 is an enlarged sectional view taken substantially along line 3-3 of FIG. I and showing the back of the nozzle of the present invention in elevation.
- FIG. 4 is a sectional view taken substantially along line 4-4 of FIG. 3.
- FIG. 5 is a side elevation of the nozzle of the, present invention.
- FIG. 6 is a partial sectional view taken substantially along line 6-6 of FIG. 5.
- FIG. 7 is an enlarged broken away view of the nozzle of the present invention shown in the operative environment of removing sediment from a corrugated pipe.
- nozzle body generally indicated by the numeral 10 in the'drawings and shown in FIG. 1 in the environment of a laterally extending sewer pipe line 11.
- the rear of nozzle body 10 receives a hose 12 whose coupling 13 is threaded into inlet bore 14 of nozzle body 10 (FIG. 4).
- Hose 12 is provided with water under high pressures and can be lowered, with nozzle body 10, through a manhole shaft 15 and into pipe line 11.
- Nozzle body 10 is fluted or grooved at a plurality of locations, as at 16, substantially along the entire length thereof thereby defining a plurality of radially extending longitudinal vanes 18.
- the outermost surface 19 of each vane 18 is generally parallel to the longitudinal axis 20 (FIG. 4) of nozzle body 10, although precisely, in the preferred embodiment, surfaces 19 are slightly arcuate together defining a circle about the axis 20 as best shown in FIGS. 2, 3 and 6. Vanes 18 are hollowed out so that they will receive water under pressure from hose 12.
- the forward or front end of vanes 18 arcuately converge from the surface 19 to a vertical front surface 21 thereby forming a bulletshaped front of nozzle body which permits and facilitates penetration into clogged pipes.
- Surface 21 is bored, as at 22, to receive an insert nozzle or jet 23 thereby forming a front port which emits a jet of water whose axis substantially corresponds to the longitudinal axis of nozzle body 10.
- the front jet acts to dislodge debris 24 which may be clogging the pipe 1 l. The loosened debris 24 is then permitted to pass through the flutes 16 and toward the rear of nozzle body 10.
- the rear of nozzle body 10 includes a generally vertically oriented surface 25 in which inlet bore 14 reposes.
- surface 25 is substantially parallel to surface 21 and at right angles to surfaces 19.
- Each vane 18 includes, near the end thereof, a surface 26 which is angular to both surfaces 19 and 21.
- a bore 28 extends through each vane surface 26 to receive an insert nozzle or thrust jet 29 thereby forming generally rearwardly directed thrust ports which emit a jet of water to propel the nozzle body 10 and hose 12 through the pipe 11.
- the jet of water from the thrust ports also acts to move at least some of the debris 24 loosened by the front jet rearwardly in pipe 11 toward manhole shaft 15.
- each thrust jet or port 29 is rearwardly inclined at an acute angle a to the longitudinal axis 20 of the nozzle body.
- Angle a is shown as being approximately which is found to be best for giving a sufficient amount of thrust and some cleaning effect.. However, an angle a at least in the range of 15 to 55 would also be appropriate.
- each thrustjet 29 is inclined at an angle B of preferably 35 from vertical surface 25 and therefore at an angle .F of preferably 55 from the radially outermost surface 19 of vanes 18.
- an angle B in the range of 15 to 55 and an angle F in the range of 35 to 75 is acceptable.
- the plane of surface 26, if extended to intersect axis 20, will have a line therein which is perpendicular to axis 20.
- each vane 18 Between surfaces 19 and 26 of each vane 18 is aflush port or volute surface 31 and a shelf32.
- Flush port surface 31 is angular to both surface 19 and surface 26 while shelf 32 is generally parallel to surface 19.
- a bore 33 extends through surface 31 to receive an insert nozzle or flush jet 34.
- surface 31 of each flush jet 34 is inclined to an angle A of preferably from vertical surface 25 and thus the angle 17 of 45 from radially outermost surface 19. However, it has been found that angles A and 1 in the range of 35 to are acceptable.
- the plane of surface 31 is tilted to the side with respect to theplane surface 26 such that one angle of intersection thereof will be at an angle of preferably about 15 but which could be as high as 20.
- a plane passing through volute surface 31, if extended to intersect axis 20, will not have a line therein which is perpendicular to axis 20 but rather, every line drawn in the plane of surface 31 will be at an angle of other than to axis 20.
- flush port insert 34 placed squarely in surface 31 with its axis 35 at right angles thereto, a small twisting force will be created by the emission of fluid through ports 34.
- this force will not twist the nozzle but will rather cause a swirl of water to be directed against the pipe 11 creating a vortex to scour the inside thereof.
- each flush port 34 being mounted on surface 31 is rearwardly inclined at an acute angle 0 to the longitudinal axis 20 of the nozzle body but will not intersect and can therefore be considered askew to axis 20.
- Angle 6 is shown asbeing approximately 45 which, combined with the 15 tilt, is found to be best for creating the flushing vortex action. However, an angle 0 at least in the range of 35 to 55 would also be appropriate.
- This action created by flusher ports 34 is particularly helpful to clean debris or sediment 24 which may still adhere to the pipe 11 after acted upon by forward jet 23. This is especially true when the pipe 11 is corrugated as shown in FIG. 7.
- a nozzle constructed and operated as described herein can clean a wide range of sizes and types of pipes, accomplishes the objects of the invention, and otherwise substantially improves the nozzle art.
- Apparatus for removing debris and the like from a pipe comprising a nozzle body having a longitudinal axis and adapted to receive water under pressure from a hose affixed to one end thereof, said nozzle body being fluted to permit the passage of debris rearwardly past said nozzle body and to define longitudinally extending vanes having radially outermost surfaces generally parallel'to said longitudinal axis, flusher port means extending through a surface on said vanes and having an axis rearwardly inclined at an acute angle to said longitudinal axis of said nozzle body, said axis of said flusher port means further being askew with respect to said longitudinal axis of said nozzle body to emit a jet of water thereby creating a vortex to scour the inside surface of the pipe when said nozzle body is introduced within the pipe, and thrust port means extending through a surface on said vanes and having an axis rearwardly inclined at an acute angle to said longitudinal axis of said nozzle body and emitting a jet of water generallly rearward
- Apparatus according to claim 1 further comprising forward port means at the front of said nozzle body having an axis generally corresponding to said longitudinal axis of said nozzle body and emitting a jet of water generally axially of said nozzle body to dislodge debris in the pipe.
- each vane includes said flusher port means and said thrust port means.
- a nozzle for removing debris and the like from a pipe comprising a plurality of hollow radially extending vanes joined to form a body having a longitudinal axis and receiving fluid under pressure from a hose affixed to one end thereof, flusher port means extending through a first surface on said vanes and having an axis rearwardly inclined at an acute angle to said longitudinal axis to emita jet of fluid to remove debris from the inside of the pipe, and thrust port means extending through a second surface on said vanes and having an axis rearwardly inclined at an acute angle to said longitudinal axis to emit a jet of fluid to propel said nozzle through the pipe, said first and second surfaces being angular to each other.
