Multiple circular holes are provided with, the baffle plate of two mutually nested circles in the middle of filter cake, is installed with, on filter cake, have the static conductive elastic force being scattered
Ball, diameter of the static conductive bouncing ball with diameter greater than circular hole on filter cake；Contact with copper screen cloth at the top of baffle plate.
There is the circular hole of diameter about 1cm on filter cake, facilitate material to enter bottom screen frame, in the middle of filter cake, there are two cylindrical gears
Plate, height about 1cm, has the static conductive bouncing ball being scattered, has copper screen cloth to filter cake edge, in circular screen above baffle plate in baffle plate
The medicated powder that static conductive bouncing ball is accumulated in can vibrating up and down and hitting copper screen mesh down in the frame course of work, prevents copper screen cloth from blocking up
Firmly.It is connected with the middle of static conductive rubber slab and shaft.
This utility model polarizes the vibration of block by air motor, and hydraulic motor drives shaft to make static conductive rubber
Plate promotes material to be screened, meanwhile, using static conductive bouncing ball to being entered by the screen mesh that medicated powder is blocked in screening process
Row impact, makes medicated powder pass through screen cloth glibly.Before air motor starts, pressure regulator valve is opened, a level pressure is passed through to shock-absorption air bag
The compressed air of power, by circular screen frame jack-up, by the oscillation amplitude for adjusting air pressure and the circular screen frame of polarization block adjustment, by control
The proportioning valve of hydraulic motor processed, adjusts the rotating speed of static conductive rubber slab.
This utility model is reasonable in design, Stability Analysis of Structures reliability, simple to operate, alleviate hand labor intensity, it is to avoid people
Body and dust directly contact, substantially increase work efficiency.
