There are two crushing rollers 12 and they are arranged opposite to each other. A crushing knife is fixed on the outer peripheral side of the crushing roller 12. The crushing knives of the two crushing rollers 12 are staggered. The kitchen waste entering the crushing chamber 111 is crushed with the cooperation of the crushing knives of the two crushing rollers 12.

[0028] The driving assembly 13 is arranged on the first housing 11. When in use, the driving assembly 13 drives the relative crushing rollers 12 to rotate in opposite directions. The driving assembly 13 includes a driving motor 131, a driving gear 132 and a transmission gear 133. The driving gear 132 is fixed to a roller shaft on one side of one of the crushing rollers 12, and the transmission gear 133 is fixed to a roller shaft on the same side of the other crushing roller 12. The driving gear 132 and the transmission gear 133 are meshed with each other. The driving motor 131 is fixed to the outer wall of the first housing 11 through a bracket provided therewith. The output shaft of the driving motor 131 is coaxial with and fixedly connected to a roller shaft on one side of one of the crushing rollers 12.

[0029] The separation device further comprises an extrusion part 2, which is arranged at the bottom of the crushing part 1 and is used for sorting the crushed kitchen waste to achieve separation of residue and liquid of the crushed kitchen waste.

[0030] The extrusion part 2 includes a second box body 21, an extrusion shaft 22 and a power part. The second box body 21 is fixed to the bottom of the first box body 11. The second box body 21 is a block-shaped structure. The length direction of the second box body 21 extends in the horizontal direction and is perpendicular to the length direction of the first box body 11. An extrusion chamber 211 is provided in the second box body 21. The first box body 11 and the second box body 21 are respectively provided with mutually aligned and connected communication ports 3. The communication ports 3 crush the communication ports 3 of the chamber 111 and the extrusion chamber 211. The crushed food waste is input into the extrusion chamber 211 through the communication ports 3.

[0031] The extrusion shaft 22 is located in the extrusion chamber 211, and the central axis of the extrusion shaft 22 is parallel to the extension direction of the extrusion chamber 211.

An extrusion bar 221 is fixedly connected to the outer peripheral side of the extrusion shaft 22, and the extrusion bar 221 extends along a spiral trajectory. A slag discharge port 212 is provided on the vertical side wall of the second box body 21 away from the connecting port 3, and the slag discharge port 212 is adjacent to the end of the extrusion shaft 22. When the extrusion shaft 22 rotates, the extrusion bar 221 drives the crushed food waste entering the extrusion chamber 211 to be transported along the central axis direction of the extrusion shaft 22 until the garbage is discharged from the slag discharge port 212, and during the food waste transmission process, the food waste is squeezed, and the liquid in the food waste is squeezed out.

[0032] At the same time, in order to improve the effect of squeezing out the liquid in the kitchen waste, a guide column with a "T"-shaped structure is fixedly connected to the outer wall of the second box body 21. Two guide columns are symmetrically arranged, and the slag discharge port 212 is located between the two guide columns. A limiting plate 24 is slidably connected to the guide column, and a power spring 25 is arranged on the outer peripheral side of the guide column. When the power spring 25 is elastically released, it pushes the limiting plate 24 to move toward the slag discharge port 212 until the limiting plate 24 abuts against the outer wall of the second box body 21. At this time, the limiting plate 24 blocks the slag discharge port 212. When discharging slag, the limiting plate 24 limits the discharge of kitchen waste, so that the pressure on the kitchen waste during the transmission process is increased, and the effect of separating the slag and liquid in the kitchen waste is improved. When the pressure on the kitchen waste in the kitchen waste pushes the limiting plate 24 away from the slag discharge port 212, the kitchen waste is discharged from the slag discharge port 212.

[0033] The power member is arranged in the second box body 21.

The push spring 82 is arranged in the third box 5, and the push spring 82 is sleeved on the outer peripheral side of the third control rope 81. One end of the push spring 82 abuts against the side of the third blocking plate 58 away from the oil delivery hole 54, and the other end abuts against the third box 5. When the water floating plate 522 approaches the drain port 521, the push spring 82 is elastically released to push the third blocking plate 58 to block the oil discharge port 531.

[0048] A rotating shaft 581 is rotatably connected to a vertical side wall of the third blocking plate 58 away from the oil discharge port 531, and a clamping strip 582 with a three-quarter arc strip structure is fixedly connected to the outer peripheral side of the rotating shaft 581; the third box body 5 is provided with a rotating groove 533, and the rotating shaft 581 and the clamping strip 582 are slidably connected to the rotating groove 533. A limit block 534 is fixedly connected to the groove wall of the rotating groove 533, and in the initial state, the limit block 534 is aligned with the gap between the two ends of the clamping strip 582.

[0049] See also Figure 4 and Figure 6 A driving column 584 is slidably mounted in the third housing 5, and a second friction layer 583 is fixedly mounted on the outer peripheral side wall of the rotating shaft 581. The driving column 584 is slidably mounted on the second friction layer 583. A driving block 585 is fixedly mounted on the outer wall of the driving column 584, and the driving block 585 protrudes into the water storage tank 52. The driving block 585 is slidably mounted on the third housing 5, and the driving block 585 is located directly above the floating plate 522. When the water-floating plate 522 moves upward, the water-floating plate 522 first abuts against the driving block 585, and the limit block 534 is located between the gaps at both ends of the clamping strip 582. Then, the driving block 585 drives the driving column 584 to move upward, and the second friction layer 583 drives the rotating shaft 581 to rotate through the rotating shaft 581, so that the clamping strip 582 slides to abut against the limit block 534, until the third blocking plate 58 is away from the oil delivery hole 54, and the clamping strip 582 abuts against the limit block 534 away from the drain port 521 (the drain port 521 is at Figure 5 On the side (marked in the middle), the top of the driving column 584 abuts against the third box body 5, restricting the floating plate 522 from continuing to move upward, while the third blocking plate 58 keeps the oil discharge port 531 open.

[0050] The implementation principle of a solid-liquid separation device for kitchen waste in the embodiment of the present application is as follows: During processing, the kitchen waste is first input into the crushing chamber 111, crushed by the crushing roller 12, and then input into the separation chamber 51. At this time, the extrusion shaft 22 rotates, so that the extrusion bar 221 drives the kitchen waste to be transmitted to the slag discharge port 212. During the transmission process, the kitchen waste is squeezed and the liquid in the kitchen waste can be squeezed out; then the liquid enters the separation chamber 51. At this time, the oil and water are stratified due to their different densities, and the oil is located above the water flow. When the water level of the liquid in the separation chamber 51 continues to rise, the oil approaches the oil delivery hole 54 and flows into the oil storage tank 53 through the oil delivery hole 54, reducing the amount of oil in the separation chamber 51; and the oil level in the oil storage tank 53 rises, driving the oil floating plate 532 to move upward, so that the first control rope 71 pulls the first blocking plate 56 to open the water delivery hole 55, and at this time the second blocking plate 57 moves downward to block the drain port 521; then the water flow in the separation chamber 51 continues to flow into the water storage tank 52, and the flow of water into the water storage tank 52 causes the oil level to stop rising, and the oil level in the oil storage tank 53 remains unchanged. Then, because the water level in the water storage tank 52 is upward, the water floating plate 522 is driven to move upward, so that the third control rope 81 pulls the third blocking plate 58 to open the oil drain port 531, discharges the oil in the oil storage tank 53, and the oil floating plate 532 can move downward close to the bottom tank wall of the oil storage tank 53. When the oil floating plate 532 moves downward, the toggle column 563 moves downward under the action of gravity, and then the first blocking plate 56 can slide to block the water delivery hole 55 and insert into the plug slot 551, pushing the control block 73 away from the water delivery hole 55, so that the second control rope 74 pulls the second blocking plate 57 upward, so that the water flow in the water storage tank 52 can be discharged through the drain port 521. As the water flow in the water storage tank 52 is discharged, the water floating plate 522 moves downward, so that the third blocking plate 58 can block the oil discharge port 531. Afterwards, as the liquid obtained by squeezing the kitchen waste continues to accumulate in the separation chamber 51, the separated oil and water continue to be discharged separately according to the same steps as above.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
