[0002] Chlorinated polyethylene is a saturated polymer material, with a white powder appearance, non-toxic and odorless, having excellent weather resistance, ozone resistance, chemical resistance and aging resistance, having good oil resistance, flame retardancy and coloring properties.

[0022] Working principle: When the utility model is in use, first, start the second electro-hydraulic push rod 5 to pull the right baffle 4 to move horizontally to the right and open the feed port 3. Then, push the hand-operated plate 32 to slide to the right against the resistance of the return spring 33 and pull out the plug plate 31 from the inner cavity of the bottom annular groove 30. Next, push the L-shaped feeding pipe 29 to move downward and rotate the L-shaped feeding pipe 29, so that the bottom end of the L-shaped feeding pipe 29 can extend into the inner cavity of the filter cylinder 2 through the feed port 3. After releasing the hand-operated plate 32, the plug plate 31 can be driven to insert into the inner cavity of the upper annular groove 30 under the action of the resilience of the return spring 33, so as to fix the height of the L-shaped feeding pipe 29, which is convenient for the staff to put the chlorinated polyethylene raw material into the inner cavity of the filter cylinder 2, and then make the right baffle 4 fit against the right side wall of the filter cylinder 2 again.

The transmission shaft 16 rotates to drive the rotating square rod 15 to rotate. The rotating square rod 15 rotates to drive the square-hole round pipe 11 to rotate. The square-hole round pipe 11 rotates to drive a plurality of stirring blades 12 to rotate in the direction opposite to the rotation direction of the filter cylinder 2, which can effectively avoid the inefficient filtration of the chlorinated polyethylene raw material in the filter cylinder 2 under the action of centrifugal force all the time.

When centrifuging the raw material, water and dilute hydrochloric acid liquid are discharged through the filter cylinder 2 from the discharge pipe 21. The emulsified chlorinated polyethylene cannot pass through the filter cylinder 2. The first electro-hydraulic push rod 8 can be started to pull the left baffle 7 to move horizontally to the left, and the emulsified chlorinated polyethylene is discharged into the inner cavity bottom of the machine shell 1 through the discharge port 6. And the second electric telescopic rod 28 is used to pull the L-shaped plate 27 to move horizontally to the left and open the discharge port 22, so that the emulsified chlorinated polyethylene can be discharged into the collection box 23 through the discharge port 22. Start the water pump 25 to pump water into the inside of the water pipe 26.
