Step 2: when urethane raw passes through filter, pressure sensitive module a and pressure sensitive module b are acquired respectively
Pressure signal in the in-out end of filter；Meanwhile pressure sensitive module a and pressure sensitive module b believe collected pressure
Number it is transmitted separately to controller；
Step 3: controller carries out at analysis pressure sensitive module a and the collected pressure signals of pressure sensitive module b
Reason, and front and back pressure difference and the threshold values of setting are subjected to comparison judgement；If front and back pressure difference is greater than or equal to the threshold values of setting, pressure
Induction module a and pressure sensitive module b continues to acquire pressure signal, and sound prompting module is closed；If front and back pressure difference
More than or equal to the threshold values of setting, then controller starts sound reminding module, and sound prompting module sounds the alarm, and reminds work
Personnel in time clean filter.
Further, the ranging from 0.02-0.04MPa of the threshold values.
The invention has the advantages that：
The present invention is by using the pressure difference in the disengaging port of real-time monitoring filter, using controller to pressure difference reality
When analysis comparison, and be equipped with sound prompting module, structure design advantages of simple, convenient for staff in time to miscellaneous in filter
Matter is purged, and is solved the problems, such as that existing urethane raw material filter accurately control can not clear up the time limit, was effectively improved
The service life of filter, while ensure that the quality stability of urethane raw conveying, there is higher market popularization value.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
