[0025] Example: Please refer to Figure 1-4 An adjustable tofu pulp and residue separator includes a connecting cylinder 2, a liquid outlet hopper 1 movably connected to the bottom of the connecting cylinder 2, a feed hopper 4 fixedly connected to the top of the connecting cylinder 2, support columns 15 fixedly connected to both sides and ends of the bottom of the feed hopper 4, a bottom plate 16 fixedly connected to the bottom of the support columns 15, and an adjustment mechanism for adjusting the switch of the adjustment device provided at the top of the feed hopper 4.
[0026] The adjustment mechanism includes a fixed plate 6, a fixed plate 6 is fixedly connected to the top of the inside of the feed hopper 4, a positioning ring 19 is fixedly connected to the top of the fixed plate 6, a connecting ring 7 is movably connected to the outside of the positioning ring 19, movable covers 5 are fixedly connected to the bottom of both sides of the outside of the connecting ring 7, a toothed block 22 is fixedly connected to the top of the inside of the connecting ring 7, a fixed frame 21 is fixedly connected to the left side of the top of the fixed plate 6, a drive motor 20 is fixedly connected to the top of the fixed frame 21, the output end of the drive motor 20 passes through the top of the fixed frame 21 and is fixedly connected to a connecting plate 23, and a drive gear 24 is fixedly connected to the bottom of the connecting plate 23.
[0027] The drive gear 24 is meshed with the tooth block 22, and the movable cover 5 is movably connected to the feed hopper 4;
[0028] The connecting plate 23 is movably connected to the connecting ring 7, and the center line of the connecting ring 7 and the center line of the feed hopper 4 are on the same vertical plane;
[0029] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, before separation, the drive motor 20 is started to drive the drive gear 24 to rotate through the connecting plate 23. The drive gear 24 drives the connecting ring 7 to rotate through the tooth block 22. The connecting ring 7 drives the movable covers 5 on both sides to rotate. Moving the movable covers 5 to both ends of the top of the feeding hopper 4 makes it easy to add materials through the feeding hopper 4. After the materials are added, the drive motor 20 is started again to drive the movable covers 5 to rotate. Moving the movable covers 5 to both sides of the top of the feeding hopper 4 can close the top of the feeding hopper 4 to prevent dust from entering. This realizes the automatic adjustment of the device switch.
[0030] A first hydraulic cylinder 9 is fixedly connected to the top of the fixed plate 6. The output end of the first hydraulic cylinder 9 passes through the fixed plate 6 and is fixedly connected to the mounting base 11. A pressing plate 3 is fixedly connected to the bottom end of the mounting base 11. Limiting sleeves 10 are fixedly connected to both sides of the top of the fixed plate 6. Limiting posts 8 are movably connected inside the limiting sleeves 10.
[0031] The limiting post 8 extends into the interior of the feed hopper 4 and is fixedly connected to the mounting base 11. The center line of the extrusion plate 3 and the center line of the connecting cylinder 2 are on the same vertical plane.
[0032] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, after the material is introduced into the connecting cylinder 2, the first hydraulic cylinder 9 is activated to push the extrusion plate 3 down through the mounting base 11. The extrusion plate 3 can extrude the material inside the connecting cylinder 2, and quickly squeeze the soy milk in the soybean residue through the filter screen 12. The soybean residue remains at the top of the filter screen 12. The mesh plate 14 can support the filter screen 12 to prevent it from deforming during extrusion. The limiting post 8 at the top of the mounting base 11 fits into the inside of the limiting sleeve 10 to limit the extrusion plate 3, so as to ensure that the extrusion plate 3 descends vertically to ensure the separation effect and prevent the soy milk from leaking out, thereby improving the separation effect.
[0033] A grid plate 14 is fixedly connected to the bottom of the liquid outlet 1, a positioning frame 13 is movably connected to the top of the grid plate 14, a filter screen 12 is fixedly connected inside the positioning frame 13, a liquid outlet valve 18 is fixedly connected to the bottom of the liquid outlet 1, and a second hydraulic cylinder 17 is fixedly connected to the top of the bottom plate 16.

[0036] Specifically, such as Figure 1 and Figure 4 As shown, after separation is completed, the second hydraulic cylinder 17 at the top of the base plate 16 is activated. The second hydraulic cylinder 17 drives the liquid outlet hopper 1 to descend through the liquid outlet valve 18. The liquid outlet hopper 1 descends to separate itself from the bottom of the connecting cylinder 2, so as to facilitate the cleaning of the soybean residue inside the liquid outlet hopper 1. The positioning frame 13 can be pulled to remove the filter screen 12 from the inside of the liquid outlet hopper 1 for cleaning. After cleaning, the positioning frame 13 is placed on the top of the grid plate 14, and the second hydraulic cylinder 17 is activated again to push the liquid outlet hopper 1 up so that it fits against the outside of the connecting cylinder 2, thus realizing convenient collection of soybean residue.
[0037] Working Principle: Before separation, the drive motor 20 is started, driving the drive gear 24 via the connecting disc 23. The drive gear 24, through the toothed block 22, drives the connecting ring 7. The connecting ring 7 then drives the movable covers 5 on both sides to rotate. Moving the movable covers 5 to the top ends of the feeding hopper 4 facilitates the addition of material. After material addition, the drive motor 20 is started again, driving the movable covers 5 to rotate and move them to the top sides of the feeding hopper 4, sealing the top of the feeding hopper 4 to prevent dust from entering. After the material is introduced into the connecting cylinder 2, the first hydraulic cylinder 9 is started, pushing the extrusion plate 3 downwards via the mounting base 11. The downward movement of the extrusion plate 3 extrudes the material inside the connecting cylinder 2, quickly squeezing the soybean pulp through the filter screen 12, leaving the soybean pulp inside. At the top of the filter screen 12, the mesh plate 14 can support the filter screen 12 to prevent it from deforming when squeezed. The limiting post 8 at the top of the mounting base 11 fits inside the limiting sleeve 10 to limit the squeezing plate 3, so as to ensure that the squeezing plate 3 descends vertically to ensure the separation effect and prevent soy milk from leaking out. After the separation is completed, the second hydraulic cylinder 17 at the top of the base plate 16 is activated. The second hydraulic cylinder 17 drives the liquid outlet hopper 1 to descend through the liquid outlet valve 18. The liquid outlet hopper 1 descends to separate it from the bottom of the connecting cylinder 2, so as to clean the soy residue inside the liquid outlet hopper 1. The positioning frame 13 can be pulled to remove the filter screen 12 from the inside of the liquid outlet hopper 1 for cleaning. After cleaning, the positioning frame 13 is placed on the top of the mesh plate 14, and the second hydraulic cylinder 17 is activated again to push the liquid outlet hopper 1 up so that it fits against the outside of the connecting cylinder 2.
