Drive aggregate to treat that the first valve 31 of hopper is opened by the first drive unit 41 and carry out discharging, and stirred by the stirring host of the main controller controls mixing plant of mixing plant; After the first preset time t 1, then drive the second valve 32 dischargings by the second drive unit 42; After the second preset time t 2, close the first valve 31 and the second valve 32.
The aggregate with two valves that discharge method of the present invention is applicable to as described in above-described embodiment is treated hopper, two valve can be controlled separately, this discharge method is first opened the first valve 31 dischargings, this discharge process discharge rate is slower, there will not be aggregate moment to be discharged in a large number in stirring host and cause the resistance moment of stirring host to increase excessive situation, after the t1 time, open the second valve 32, two valves are opened simultaneously, with fast speed discharging, but now aggregate has drawn off a part, aggregate treats that the aggregate surplus in hopper is less, thereby in the time that remaining aggregate is quickly discharged in stirring host, can greatly reduce and be discharged in a large number and in stirring host, cause the resistance moment of stirring host to increase excessive situation because of aggregate moment.Thereby discharge method of the present invention can be avoided the current peak of stirring host motor to uprush exceeding electric current threshold peak, thereby can effectively prevent that the motor of stirring host from burning out or the vexed machine of main frame, reduce the fault rate of stirring host.
Wherein, the first preset time t 1 and the second preset time t 2 can be the values that those skilled in the art set according to existing discharging working experience, and as preferred, the present invention obtains the first preset time t 1 and the second preset time t 2 by following manner:
Drive by the first drive unit 41 before the first valve 31 opens the step of carrying out discharging described, also comprise:
Judge that aggregate treats the aggregate type in hopper;
According to the default corresponding relation of each aggregate type and each time value, determine that aggregate treats corresponding the first preset time t 1 and the second preset time t 2 of aggregate type in hopper.
This mode need to be set up the default corresponding relation of each aggregate type and each time value in advance, and this default corresponding relation can rule of thumb be set up by those skilled in the art, also can set up by set program.When making to adopt discharge method discharging of the present invention; can avoid occurring aggregate moment to be discharged in a large number in stirring host and cause the resistance moment of stirring host to increase excessive situation; thereby the current peak of avoiding stirring host motor is uprushed and is exceeded electric current threshold peak; effectively protection stirring host, the each aggregate type in the present invention and the default corresponding relation of each time value are preferably installed following steps and are set up:
First, treat the default discharge time t1 ' of hopper aggregate type and t2 ' for aggregate.This t1 ' and t2 ' can be according to those skilled in the art's experiences, for the feature of aggregate type, as humidity, granular size, proportioning etc., a default initial discharge time, and when by virtue of experience judgement adopts this discharging default discharge time, do not occur as far as possible aggregate moment to be discharged in a large number in stirring host and cause the resistance moment of stirring host to increase excessive situation, avoiding the current peak of stirring host motor to uprush and exceed electric current threshold peak.
Next above-mentioned t1 ' and t2 ' are revised.
Open aggregate and treat the first valve 31 dischargings of hopper, and stirred by control stirring hosts such as mixing plant master controllers; After elapsed time t1 ', open the second valve 32 dischargings, and duration t2 '; In this discharging whipping process, current peak I while obtaining stirring host stirring work, and the electric current threshold peak I0 of this current peak I and stirring host is compared, if the I getting in whole process is all less than I0, the first preset time t 1 and the second preset time t 2 using t1 ' and t2 ' as corresponding aforementioned aggregate type, calls when adopting discharge method of the present invention to carry out discharging; If in whole process there is the situation of I>I0 or I=I0 in certain I getting, strengthen the value of this t1 ', t1 ' and t2 ' repeat above-mentioned steps, until can be served as the first preset time t 1 and second preset time t 2 of the described aggregate type of correspondence.
It should be noted that, on the one hand, because above-mentioned steps is intended to the first preset time t 1 and the second preset time t 2 in order to find out corresponding described aggregate type, set up the default corresponding relation of each aggregate type and each time value, therefore, occurring after the situation of I>I0 or I=I0, can wait this discharging to complete and also can directly stop this discharging, then repeat above-mentioned steps, until can determine the first preset time t 1 and second preset time t 2 of corresponding described aggregate type; On the other hand, if desired repeat above-mentioned steps, in the time of preset time t 1 ' and time t2 ', the value of t1 ' can adopt the last time to occur the t1 ' strengthening after the situation of I>I0 or I=I0.
Further it should be noted that, carry out discharging according to said method, the situation that occurs I>I0 or I=I0 is after normally the first valve 31 and the second valve 32 are opened simultaneously, aggregate treats in hopper that residue aggregate moment is discharged in stirring host, cause the shaft resistance moment of stirring host to increase excessive, cause the increase of main motor load moment to cause, therefore, in the step of the above-mentioned default corresponding relation of setting up each aggregate type and each time value, pass through to strengthen the value of t1 ', to increase the amount that draws off aggregate by discharging at a slow speed, reduce aggregate and treat the aggregate surplus in hopper, thereby in the time that the first valve 31 and the second valve 32 are opened simultaneously, reducing as far as possible moment is discharged into the aggregate in stirring host, the shaft resistance moment that prevents stirring host increases excessive, and then prevent that main motor load moment from increasing excessive current peak I>I0 or the I=I0 that causes main motor.
Ability technical staff should be understood that, along with the carrying out of discharging, stirring host is subject to the resistance difference of aggregate while stirring, therefore, the current peak I of stirring host may change, especially when opening after the second valve 32, residue aggregate can be quickly discharged in stirring host, the variation meeting of current peak I is fairly obvious, therefore, above-mentioned, t1 ' and t2 ' are carried out in revision process, need within the time period of this t1 '+t2 ', constantly obtain current peak I, and itself and electric current threshold peak I0 are compared getting after current peak I.
In addition, electric current threshold peak I0 can be the motor rated current of stirring host, also can be a current value of setting according to stirring host working condition, it will be understood by those skilled in the art that, I0 should reflect the limiting condition of stirring host work, the current peak of the motor of stirring host exceedes I0 and means that in stirring host, aggregate is too many, causes motor overload work.
According to the description of the above-mentioned default corresponding relation of setting up each aggregate type and each time value, the first preset time t 1 and the second preset time t 2 are through getting t1 ' and t2 ' revision, and follow in the process of revision according to being to take different t1 ' and t2 ' for different aggregate type, and make to there will not be in discharge process and increase the excessive I>I0 of making or I=I0 because of the resistance moment of stirring host.On this basis, discharge method of the present invention is called corresponding the first preset time t 1 and the second preset time t 2 according to different aggregate type and is carried out discharging, first open the first valve 31 dischargings, this discharge process discharge rate is slower, there will not be aggregate moment to be discharged in a large number in stirring host and cause the resistance moment of stirring host to increase excessive situation, after the t1 time, open the second valve 32, two valves are opened simultaneously, with fast speed discharging, but now aggregate has drawn off a part, remaining aggregate is quickly discharged into and in stirring host, also there will not be aggregate moment to be discharged in a large number in stirring host and cause the resistance moment of stirring host to increase excessive situation.Thereby discharge method of the present invention can be avoided the current peak of stirring host motor to uprush exceeding electric current threshold peak, thereby can effectively prevent that the motor of stirring host from burning out or the vexed machine of main frame, reduce the fault rate of stirring host.
According to existing discharging experience, in order to ensure discharging efficiency and mixing effect, conventionally maintain discharging total time in the specific time, for example 20s, therefore, t1+t2's and be generally fixed value, corresponding t1 '+t2 ' with also should be mutually fixed value.Further, under normal circumstances, t1 < t2, correspondingly, t1 ' < t2 '.For example, t1 is 5s, t2 is 15s, in the time of discharging, first open the first valve 31 discharging 5s at a slow speed, then open the second valve 32 quickly discharging materials, now discharge rate is fast, can ensure that aggregate unsnatches within 15s, then close the first valve 31 and the second valve 32, so that aggregate is treated that hopper receives and held next group aggregate.
Correspondingly, embodiments of the invention also provide a kind of concrete mixing plant, and it is provided with above-mentioned aggregate and treats hopper.Above-mentioned aggregate treats that the bucket valve of hopper comprises the first valve and the second valve, in the time of discharging, can adopt above-mentioned discharge method, therefore, this concrete mixing plant also has with above-mentioned aggregate treats that hopper and above-mentioned aggregate treat the beneficial effect that the discharge method of hopper is identical, repeats no more.
