Description
Technical field
The present invention relates to the technical field of chemical industry hot-melt adhesive powder " material of waking up " technique, a kind of specifically method that freezing powder is rapidly heated.
Background technology
Copolymer nylon, copolyester hot melt adhesive are with the production process of pulverulence for lining cloth of weaving, and therefore the PUR of graininess or bulk will be made the powder of different grain size distribution by hot-melt adhesive powder factory.Because the brittle temperature of copolymer nylon, copolyesters is very low, being generally-30 DEG C--50 DEG C needs under liquid nitrogen exists, carry out the powder that deep cooling crush just can obtain the size distribution needed.
After deep cooling crush, from pulverizer powder out at-30 DEG C about--20 DEG C, need intensification to make it reach environment temperature, PUR industry is called " material of waking up ".But, if be directly exposed to intensification in air can make powder " expanded " because the nitrogen be contained in freezing powder gasifies rapidly.The powder particle surface of " expanded " is coarse, bulk density decline affects its mobile performance and brings very large trouble to lining cloth production.Meanwhile, freezing powder exposes and can absorb moisture in atmosphere in a large number and cause unnecessary problem, only have for this reason freezing powder is placed on lining form sack in be placed in air and slowly heat up, usually need 36-48 hour.So just make powder occupy a large amount of production spaces and also extend the production cycle.
Summary of the invention
The object of the present invention is to provide a kind of method that freezing powder is rapidly heated, it utilizes the rake type drier improved, and effectively shortens the drying time of freezing powder, decreases production space, shortens the production cycle.
To achieve these goals, technical scheme of the present invention is: a kind of method that freezing powder is rapidly heated, it is characterized in that: described in the method that is rapidly heated be, adopt the rake type drier of transformation as heating device, the freezing powder of-3 DEG C ~-20 DEG C is put into rake type drier inner chamber, this rake type drier inner chamber is provided with one with the turning cylinder of ribbon, ribbon coiling turning cylinder is arranged, this ribbon inner chamber hollow and UNICOM mutual to the hollow cavity of turning cylinder, the recirculated water of 20 DEG C-40 DEG C flows into from the water inlet of turning cylinder one end, after ribbon inner chamber, flowed out by the delivery port of the turning cylinder other end, the flow of recirculated water is not less than 30m
3/ h, rake type drier inner chamber is filled with dry nitrogen, the pressure of rake type drier inner chamber is made to be increased to 0.4Mpa-0.5Mpa, start turning cylinder to stir freezing powder, turning cylinder rotating speed during stirring is 36rpm, and mixing time is 30 minutes-40 minutes, then passes into the recirculated cooling water of 20 DEG C-40 DEG C in the chuck of rake type drier, carry out drying to the powder in rake type drier, the flow of recirculated cooling water is not less than 30m
3/ h, when the powder in this rake type drier reaches 20 DEG C, stop dry, powder is taken out, described freezing powder is copolyamide or copolyesters, and the cavity middle section of turning cylinder hollow cavity is provided with dividing plate, and turning cylinder hollow cavity is separated into two independently cavitys by this dividing plate, described ribbon is coiled in turning cylinder outside in the shape of a spiral, and the spiral outer end of described ribbon tapers off to a point.
The invention discloses a kind of method that freezing powder is rapidly heated, it adopts follow-on rake type drier, and coordinate new drying technology process, the problem that powder " cruelly empty " can be avoided to produce can improve again the speed of " material of waking up " greatly, can shorten the awake material time of 1 hours compared to existing technologies.
