Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a replacement device for a plate and frame filter press. Background Art

[0002] The plate and frame filter press consists of a group of filter chambers composed of alternately arranged filter plates and filter frames. There are grooves on the surface of the filter plates, and the protruding parts are used to support the filter cloth. There are through holes on the corners of the filter frames and filter plates. After assembly, they form a complete channel that can pass suspension, washing water and discharge filtrate.

[0022] See also Figure 1-4In the utility model, the plate and frame filter press replacement device includes a separation cylinder 5, the inner wall of the separation cylinder 5 is fixedly inlaid with a first bearing 9 and a second bearing 16, the inner ring of the first bearing 9 and the inner ring of the second bearing 16 are fixedly installed with a spiral extrusion blade 17, the upper surface of the right end of the separation cylinder 5 is fixedly connected with an introduction pipe 7, the bottom surface of the right end of the separation cylinder 5 is fixedly connected with a liquid guide pipe 10, the bottom surface of the left end of the separation cylinder 5 is fixedly connected with a mud guide pipe 4, the bottom surface of the separation cylinder 5 is fixedly installed with two groups of support legs 2, and the bottom surface of each support leg 2 is fixedly installed with a support seat 1, the first The first bearing 9 and the second bearing 16 jointly fix the spiral extrusion blades 17. The pitch of the spiral extrusion blades 17 gradually decreases from right to left, so that the spiral extrusion blades 17 can continuously squeeze the mud in the mud liquid into sheets when rotating. The separated liquid can flow from the inner bottom wall of the separation cylinder 5 to the liquid guide tube 10 under the action of gravity, and finally the liquid guide tube 10 drips onto the top of the filter screen 8. The two groups of support legs 2 jointly support the separation cylinder 5, and the four support seats 1 increase the contact area with the ground, so that the device can be placed stably.

[0023] A water tank 11 is fixedly installed on one side where the two groups of supporting legs 2 are close to each other. A filter screen 8 is fixedly installed on the inner wall of the water tank 11. By installing the filter screen 8 on the inner wall of the water tank 11, large particles of impurities in the dripping liquid can be effectively filtered. The right side of the water tank 11 is fixedly connected to a dewatering pipe 13. A valve 12 is fixedly installed on the outer surface of the dewatering pipe 13. The valve 12 is electrically connected to the controller 3 through a wire. The staff can control the valve 12 to open or close through the controller 3, so that the liquid inside the water tank 11 can be discharged through the dewatering pipe 13.

[0024] A chassis 6 is fixedly installed on the left side of the separation cylinder 5, and a heat dissipation window 14 is fixedly inlaid on the left side of the chassis 6. By inlaying the heat dissipation window 14 on the left side of the chassis 6, air can be easily circulated to the inside of the chassis 6 through the heat dissipation window 14, so that the motor 15 inside the chassis 6 can be easily cooled and dissipated. A motor 15 is fixedly installed on the inner wall of the chassis 6, and the output end of the motor 15 is fixedly installed on the left end of the spiral extrusion blade 17.

A controller 3 is fixedly installed on the front side of one of the supporting legs 2, and the controller 3 is electrically connected to the motor 15 through a wire. By installing the controller 3 on the front side of one of the supporting legs 2, the staff can control the device through the controller 3 without bending over, and the motor 15 is electrically connected to the controller 3 through a wire, so that the staff can conveniently start or shut down the motor 15 through the controller 3.

[0025] The working principle of the utility model is:

[0026] First, the staff uses a connecting pipe to connect the output end of the flocculation box with the inlet pipe 7, and then the staff starts the motor 15 through the controller 3. The output end of the motor 15 rotates to drive the spiral extrusion blade 17 to rotate. The spiral extrusion blade 17 rotates to continuously separate the solid and liquid, and extrude the solid mud blocks into shape. The liquid flows along the inner wall of the separation cylinder 5 to the inside of the liquid guide tube 10 and drips to the top of the filter screen 8 through the liquid guide tube 10. When the spiral extrusion blade 17 rotates, it pushes the fixed mud blocks to gradually move to the left, and finally squeezes the solid mud blocks out of the inside of the separation cylinder 5 through the mud guide tube 4.
