[0024] The interior of the filter press case 1 is provided with a right-angle extrusion plate 22 and an I-shaped extrusion plate 23. The gap between the right-angle extrusion plate 22, the I-shaped extrusion plate 23 and the filter press case 1 forms an extrusion groove 24. The output end of the upper motor 14 is fixed with a screw shaft 25. The upper and lower sides of the surface of the screw shaft 25 are threadedly connected with an upper screw ring 26 and a lower screw ring 27. An inner transfer block 28 is fixed on the upper and lower screw rings 26 and the lower screw ring 27. An outer transfer block 29 is fixed on the I-shaped extrusion plate 23. A push-pull rod 30 is rotatably connected between the inner transfer block 28 and the outer transfer block 29. The waste residue inside the slag collecting box 6 can be re-transported to the feed pipe 4 through the reflux pump 10 and the reflux pipe 11, and the waste residue can be transported to the extrusion groove 24 again through the branch conduit 3. Therefore, the waste residue can be filter-pressed again, and this cycle can be repeated, so that the waste residue can be filter-pressed more efficiently and thoroughly.

When the screw shaft 25 rotates, it can drive the upper screw ring 26 and the lower screw ring 27 to move up and down, so that the upper screw ring 26 and the lower screw ring 27 can drive the telescopic rectangular frame composed of the right-angle extrusion plate 22 and the I-type extrusion plate 23 to extend or contract through the push-pull rod 30.

[0026] Furthermore, the I-shaped extrusion plate 23 is slidably connected to the right-angle extrusion plates 22 on both sides thereof, and four groups of right-angle extrusion plates 22 and I-shaped extrusion plates 23 are provided respectively, and the right-angle extrusion plates 22 and I-shaped extrusion plates 23 form a telescopic rectangular frame plate, which facilitates the extrusion of the waste residue inside the extrusion groove 24 through the telescopic rectangular frame plate composed of the right-angle extrusion plates 22 and the I-shaped extrusion plates 23, so as to perform filter press treatment on the waste residue.

[0027] Furthermore, the slag discharge trough 12, the trapezoidal slag discharge box 13, the spray conduit 18, the crushing cylinder 5 and the slag collecting box tube 6 are interconnected, and the spray conduit 18, the filter hole 19, the outer tube 20, the guide pipe 21 and the liquid collecting box tube 8 are interconnected, so that the waste slag after filtration can be transported to the slag collecting box tube 6 through the slag discharge trough 12, the trapezoidal slag discharge box 13, the spray conduit 18 and the crushing cylinder 5, and the waste liquid can be transported from the guide pipe 21 to the liquid collecting box tube 8 through the filter hole 19 for centralized collection.

[0028] Furthermore, a spray head is provided on the spray conduit 18, and the spray head extends to the interior of the spray conduit 18. The filter holes 19 are opened below the surface of the spray conduit 18, and multiple groups are provided along the circumference and axial direction of the spray conduit 18, so that the waste residue moving downward inside the spray conduit 18 can be sprayed and flushed through the spray head on the spray conduit 18.

[0029] Furthermore, the slag collecting box 6, the reflux pump 10, the reflux pipe 11, the feed pipe 4, and the branch pipe 3 are interconnected, and the bottom end of the branch pipe 3 is located inside the extrusion tank 24. This facilitates the reflux pump 10, the reflux pipe 11, the feed pipe 4, and the branch pipe 3 to transport the waste slag inside the slag collecting box 6 back into the extrusion tank 24 and re-filter the waste slag. This cycle is repeated to improve the effect of filtering the waste slag.

[0030] When in use, the polyaluminium chloride waste residue can be poured into the extrusion groove 24 through the feed pipe 4 and the branch conduit 3, and then the upper motor 14 is started to drive the screw shaft 25 to rotate. When the screw shaft 25 rotates, the upper screw ring 26 can be driven to move downward and the lower screw ring 27 can be driven to move upward. Therefore, the upper screw ring 26 and the lower screw ring 27 can drive the telescopic rectangular frame composed of the right-angle extrusion plate 22 and the I-type extrusion plate 23 to stretch outward through the inner adapter block 28 and the outer adapter block 29, and the waste residue inside the extrusion groove 24 is subjected to pressure filtration treatment, and the waste residue can be evenly attached to the inner and outer inner walls of the extrusion groove 24 of the telescopic rectangular frame after being squeezed, so as to uniformly pressure filter the waste residue, and when the telescopic rectangular frame shrinks, the waste residue after pressure filtration enters the spray conduit 18 through the slag discharge groove 12. When the waste residue moves downward inside the spray conduit 18, the waste residue is discharged from the spray conduit 18. During the operation, the surface of the waste residue can be sprayed with flushing liquid through the spray conduit 18 to flush the waste residue, and the flushed waste liquid enters the outer tube 20 through the filter hole 19, and can be collected by the liquid collecting box 8 through the guide pipe 21. After the flushed waste residue enters the inside of the crushing tube 5, the lower motor 15 drives the crushing piece 17 to rotate through the rotating shaft 16, and evenly crushes the agglomerated waste residue.
