System, those skilled in the art can select the specifications and models of strainer according to the type of equipment, meanwhile, there are many seams and edge sealing can
Selective, strainer has the advantages that some column such as product good mechanical stability, wear-resistant, easy slag dumping, water permeability number.
According to an embodiment of the invention, soiling solution enters in the cavity of drum through soiling solution liquid back pipe, soiling solution is first passed through on drum
Trawlnet after through strainer enter after filtering net liquid case for machine tooling use, strainer stops impurity in soiling solution, by not
Disconnected precipitating forms filter cake, and filter cake is after the accumulation of strainer surface reaches certain thickness, and the water permeability of strainer declines, and soiling solution is in strainer
Liquid level in cavity is formed by with drum to increase, and when detection switch detects that liquid level reaches set high liquid level, is sent out to motor
News, the rotation of motor driven driving roller device, strainer rotate with it, and the strainer that surface is attached with filter cake part produces, and strainer is permeable
Performance recovery, soiling solution liquid level in the cavity that strainer and drum are formed decline, and motor stalls circuit sequentially, in which:
When strainer rotation, when by the right side of the first roller, filter cake is separated with strainer under the effect of gravity, falls into lower section
Filter residue case, when strainer rotates, brush roll is started to work, and brush roll linear resonance surface velocity is greater than strainer linear velocity, remains on strainer
Filter cake separated under the action of brush roll with strainer, fall into lower section filter residue case.
In strainer rotation, drying unit starts work simultaneously, reduces the content of moisture in filter cake, is convenient for filter cake and strainer
Separation, while the water content for falling into filter residue in filter residue case is reduced, thus convenient for Rose Box is discharged in the dregs on strainer, solve
Dregs blocking filter bag cause frequently replace filter bag the problem of, it can be achieved that filter bag recycling, saved production cost,
Improve production efficiency.
In strainer rotation, the clean cutting fluid of net liquid case is pumped to instead by recoil pump startup work by backflushing pipe
Nozzle is rushed, clean cutting fluid is sprayed by recoil nozzle, rinses strainer, and the soiling solution for rinsing generation is collected by soiling solution accumulator tank, is led to
It crosses recoil soiling solution liquid back pipe and returns to soiling solution liquid back pipe, and then carry out circulating filtration.
Device according to an embodiment of the present invention, soiling solution enter in the cavity of drum through soiling solution liquid back pipe, and liquid portion passes through
Enter net liquid case after strainer filter to use for machine tooling, strainer stops impurity in soiling solution, to form filter cake by constantly precipitating, and filters
Cake is after the accumulation of strainer surface reaches certain thickness, and strainer is rotated with driving roller device, and surface is attached with the strainer of filter cake part
It produces, so that the recycling of strainer is realized, meanwhile, which is additionally provided with scrapings device, drying unit etc. and carries out to filter cake
Removing, drying and processing, the device is good with strainability, is recycled filtering, reliable for operation, simple and compact for structure, maintenance cost
Low some column advantages.
