Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-5 As shown, the technical solution adopted by this utility model is as follows: a fully enclosed solid-liquid separator with filtration function. It includes a processing tank 1. A feed tank 2 is fixedly installed above the processing tank 1. The inner cavities of the processing tank 1 and the feed tank 2 are connected. A crushing roller 4 is rotatably installed inside the feed tank 2. The crushing roller 4 is used to crush the material. The crushed material enters the processing tank 1.

[0027] The upper end of the feeding box 2 is provided with a feeding port, and the upper end of the feeding box 2 is provided with a cover plate 3. One end of the cover plate 3 is rotatably connected to the feeding box 2 through a rotating shaft.

[0028] During the crushing process, the cover plate 3 covers the feed inlet of the feed box 2 to prevent material from splashing. A rotatable connection is provided between the feed box 2 and the cover plate 3 to facilitate the opening of the feed inlet of the feed box 2 by the cover plate 3.

[0029] A sieve plate 17 is fixedly installed inside the processing tank 1. A collection box 19 is installed inside the processing tank 1 below the sieve plate 17. Furthermore, a liquid collecting hopper 18 is fixedly installed below the sieve plate 17. The liquid collecting hopper 18 is conical, and the collection box 19 is located below the liquid collecting hopper 18.

[0030] The liquid collecting hopper 18 guides the liquid passing through the sieve plate 17 and directs the liquid into the collecting box 19.

[0031] The processing box 1 is equipped with an extrusion assembly located above the sieve plate 17.

[0032] The extrusion assembly is used to compress the pulverized material, facilitating the separation of liquid and solid materials. The liquid material falls into the collection box 19 through the sieve plate 17.

[0033] Specifically, the extrusion assembly includes a first extrusion plate 13 and a second extrusion plate 16. The first extrusion plate 13 and the second extrusion plate 16 are parallel to each other. The first extrusion plate 13 and the second extrusion plate 16 are slidably connected to the processing box 1. The first extrusion plate 13 and the second extrusion plate 16 are located above the sieve plate 17. The moving direction of the first extrusion plate 13 and the second extrusion plate 16 is perpendicular to the moving direction of the push plate 6. The first extrusion plate 13 is perpendicular to the push plate 6.

[0034] Furthermore, a connecting plate 14 is provided on each side of the processing box 1. The connecting plate 14 is located on the outside of the processing box 1. One connecting plate 14 corresponds to the first extrusion plate 13. The other connecting plate 14 corresponds to the second extrusion plate 16. A sliding rod 15 with its axis arranged in the horizontal direction is fixedly installed between the connecting plate 14 and the first extrusion plate 13, and between the connecting plate 14 and the second extrusion plate 16. The sliding rod 15 is slidably connected to the processing box 1.

[0035] A second cylinder 12 is fixedly installed on the processing box 1. The second cylinder 12 is a double-headed cylinder. The extension and retraction direction of the output end of the second cylinder 12 is parallel to the axis of the sliding rod 15. The two output ends of the second cylinder 12 are respectively fixedly connected to two connecting plates 14.

[0036] The second cylinder 12 is activated, which drives the two connecting plates 14 to move towards each other. The connecting plates 14 drive the first extrusion plate 13 and the second extrusion plate 16 to move towards each other. The movement of the first extrusion plate 13 and the second extrusion plate 16 towards each other causes the material between the first extrusion plate 13 and the second extrusion plate 16 to be extruded. The first extrusion plate 13 and the second extrusion plate 16 perform solid-liquid separation on the material.

[0037] A push plate 6 is horizontally slidably mounted on the processing box 1, located above the sieve plate 17. A discharge port is provided on one side of the processing box 1. A lifting plate 7 is vertically slidably mounted at the discharge port.

[0038] Specifically, a first cylinder 5 is fixedly installed on the processing box 1. The extension and retraction direction of the output end of the first cylinder 5 is the same as the movement direction of the push plate 6, and the extension and retraction end of the first cylinder 5 is fixedly connected to the push plate 6.

[0039] Start the first cylinder 5. The first cylinder 5 extends and drives the push plate 6 to move. The push plate 6 pushes the material above the screen plate 17 and pushes the material to the discharge port.

[0040] Furthermore, the discharge port of the processing box 1 is located on the side of the processing box 1 opposite to the first cylinder 5, and a vertical clearance groove is provided on the side wall of the discharge port of the processing box 1, and the lifting plate 7 is slidably installed in the clearance groove.

[0041] A drive assembly for driving the vertical movement of the lifting plate 7 is installed between the lifting plate 7 and the processing box 1.

[0042] Specifically, the drive assembly includes: a mounting plate 8, a connecting rod 9, and a rotating plate 10.

[0043] Two connecting rods 9 are provided. The axis of the connecting rod 9 is perpendicular to the moving direction of the push plate 6. The two connecting rods 9 are respectively fixed to the side wall of the processing box 1 perpendicular to the lifting plate 7.

[0044] Two rotating plates 10 are provided. Each of the two rotating plates 10 corresponds one-to-one with one of the two connecting rods 9. The rotating plates 10 and their corresponding connecting rods 9 are rotatably connected. Each rotating plate 10 includes a horizontal bar and a vertical bar, which are fixedly connected to each other, making the rotating plate 10 L-shaped.

[0045] Two mounting plates 8 are provided, each corresponding to one of the rotating plates 10. The mounting plates 8 are fixedly installed on the inner side of the lifting plate 7. A horizontal rectangular groove is formed on the mounting plate 8. A connecting block 11 is fixedly installed at the end of the horizontal bar of the rotating plate 10 away from the vertical bar. The connecting block 11 is located in the rectangular groove and is slidably connected to the rectangular groove.

[0046] Please see the appendix Figure 4 and attached Figure 5 When the lifting plate 7 blocks the discharge port, the lower end of the vertical rod of the rotating plate 10 is located below the connecting rod 9. When the push plate 6 moves to contact the vertical rod of the rotating plate 10, the push plate 6 pushes the rotating plate 10 to rotate counterclockwise via the vertical rod. When the rotating plate 10 rotates counterclockwise, it pushes the lifting plate 7 upward via the connecting block 11 and the mounting plate 8. The upward movement of the lifting plate 7 opens the discharge port. The push plate 6 continues to move, pushing the solid material out of the processing box 1. During the process of the push plate 6 moving in the opposite direction and disengaging from the rotating plate 10, under the action of gravity, the lifting plate 7 moves downward, simultaneously causing the connecting block 11 and the mounting plate 8 to rotate the rotating plate 10 clockwise to reset.

[0047] The specific usage process of this application is as follows:

[0048] Pour the material requiring solid-liquid separation into the feed hopper 2. Start the crushing roller 4 to crush the material. During the crushing process, cover the material with the cover plate 3 to prevent the crushed material from splashing.

[0049] The crushed material falls onto the sieve plate 17 of the processing box 1. The second cylinder 12 is started, which drives the first extrusion plate 13 and the second extrusion plate 16 to move closer to each other. The first extrusion plate 13 and the second extrusion plate 16 extrude the material, which improves the degree of solid-liquid separation and makes the solid-liquid separation more complete.

[0050] After the first extrusion plate 13 and the second extrusion plate 16 move relative to each other, the second cylinder 12 retracts, causing the first extrusion plate 13 and the second extrusion plate 16 to move in opposite directions and reset.

[0051] The liquid falls through the sieve plate 17 into the collection box 19 below the liquid collecting hopper 18.

[0052] The first cylinder 5 is activated to move the push plate 6, thereby pushing the solid material on the screen plate 17 toward the discharge port.

[0053] When the push plate 6 moves to contact the vertical rod of the rotating plate 10, the push plate 6 pushes the rotating plate 10 to rotate counterclockwise via the vertical rod. As the rotating plate 10 rotates counterclockwise, it pushes the lifting plate 7 upward via the connecting block 11 and the mounting plate 8. The upward movement of the lifting plate 7 opens the discharge port. The push plate 6 continues to move, pushing the solid material out of the processing box 1. During the reverse movement of the push plate 6 and its disengagement from the rotating plate 10, under the influence of gravity, the lifting plate 7 moves downward, simultaneously causing the connecting block 11 and the mounting plate 8 to rotate the rotating plate 10 clockwise to reset it.

[0054] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
