[0002] Restaurant waste primarily refers to food scraps, food processing waste, and waste cooking oils and fats generated during food processing, catering services, and workplace catering. During the restaurant waste recycling process, a solid-liquid separator is required to separate solid waste from liquid waste such as sewage oil and fats.

[0003] In the Chinese utility model patent with publication number CN220804919U, a solid-liquid separator for food waste is disclosed. When processing waste, the waste can be crushed to improve the processing effect, and then the waste is spirally conveyed by a spiral conveyor roller to separate the waste and liquid, thereby greatly improving the processing efficiency and effect. However, after searching and combining it with the actual experience of food waste treatment, it was found that the device mainly uses gravity to separate and recover grease while horizontally conveying the waste, thereby completing solid-liquid separation. In actual practice, due to the certain viscosity of grease, some grease adheres to the surface of the food waste and is difficult to separate, resulting in the problem of insufficient separation in the device.

[0004] Therefore, there is an urgent need to improve the existing solid-liquid separator for kitchen waste recycling and provide a solid-liquid separator with a centrifugal separation function and more sufficient solid-liquid separation. Utility Model Content

A second opening 22 is provided at the left end top of the waste liquid recovery component 2 corresponding to the bottom liquid outlet of the solid-liquid separation component 7.

[0029] As a preferred embodiment, on the basis of the above structure, the crushing device further includes a first motor 4 and a crushing rod 5. The first motor 4 is fixedly installed at the top center of the feed hopper 3 through a bracket. The output end of the first motor 4 is fixedly connected to the crushing rod 5 with a blade. The crushing rod 5 extends longitudinally to the inside of the feed hopper 3.

[0030] As a preferred embodiment, on the basis of the above structure, the waste liquid recovery component 2 further includes a recovery box 21, a second opening 22, a discharge pipe 23 and a valve 24. The longitudinal section of the recovery box 21 is "L"-shaped, and the top of the recovery box 21 is welded and fixed to the conveying pipe 1. A second opening 22 is provided at the top left end of the recovery box 21 and directly below the solid-liquid separation component 7. The bottom left outer wall of the recovery box 21 is inlaid with a discharge pipe 23, and a valve 24 is installed in the middle of the discharge pipe 23.

[0031] In this embodiment, the recovery box 21 is used to temporarily store the recovered grease, and the discharge pipe 23 and the valve 24 are provided to facilitate the discharge of the grease.

[0032] As a preferred embodiment, on the basis of the above structure, the connecting component 6 further includes a discharge pipe 61, a cross bar 62, a mounting shaft 63, small conical teeth 64, a docking pipe 65 and a hook 66. The discharge pipe 61 is fixed at the bottom of the left end of the conveying pipe 1, and the top of the discharge pipe 61 is inlaid and connected with the conveying pipe 1. The bottom inner wall of the discharge pipe 61 is fixedly installed with a cross bar 62, and the middle bearing of the cross bar 62 is connected to the mounting shaft 63. The longitudinal section of the mounting shaft 63 is an inverted "T" shape and the top is fixedly connected to the small conical teeth 64. The outer bearing sleeve of the bottom end of the discharge pipe 61 is provided with a docking pipe 65. The middle outer wall of the docking pipe 65 is symmetrically fixed with a hook 66 for connecting the solid-liquid separation component 7. The left and right ends of the bottom of the mounting shaft 63 are fixedly connected to the inner wall of the docking pipe 65.

[0033] As a preferred embodiment, on the basis of the above structure, further, the small conical teeth 64 are engaged with the large conical teeth 11, and the diameter length of the small conical teeth 64 is only one third of the diameter length of the large conical teeth 11; the mounting shaft 63 is linked with the auger 10, and the rotation speed of the mounting shaft 63 is greater than the rotation speed of the auger 10.

[0034] In this embodiment, when the auger 10 and the large conical teeth 11 are controlled to rotate, the small conical teeth 64 engaged with the large conical teeth 11 can rotate synchronously, so that the mounting shaft 63 can be controlled to drive the docking tube 65 to rotate rapidly, and the docking tube 65 can drive the solid-liquid separation component 7 to rotate through the hook 66, so that the food waste can be subjected to rotational centrifugal separation, and the separation is more complete.

[0035] As a preferred embodiment, on the basis of the above structure, the solid-liquid separation component 7 further includes a separation net barrel 71, a liquid collecting barrel 72 and a hanging ring 73. The top of the separation net barrel 71 is slidably sleeved on the outside of the bottom end of the docking pipe 65, and the outer side of the separation net barrel 71 is fixedly sleeved with a liquid collecting barrel 72. Hanging rings 73 are rotatably installed on the left and right ends of the top of the liquid collecting barrel 72. The two hanging rings 73 correspond to the two hooks 66 respectively and are adapted to each other.

[0036] In this embodiment, the connection and disassembly between the solid-liquid separation assembly 7 and the docking pipe 65 are facilitated by rotating the hanging ring 73 installed on the top of the liquid collecting barrel 72.

[0037] As a preferred embodiment, based on the above structure, further, the bottom end of the liquid collecting barrel 72 is a funnel-shaped structure.

[0038] In this embodiment, the funnel-shaped bottom of the liquid collecting barrel 72 is utilized to facilitate the recovery of the thrown-out grease into the recovery box 21 through the second opening 22 , so as to facilitate subsequent unified processing.

[0039] On the basis of the above structure, preferably, the bottom liquid outlet of the liquid collecting barrel 72 is located directly above the center of the second opening 22. In order to avoid the waste liquid splashing outside the second opening 22, the bottom liquid outlet of the liquid collecting barrel 72 can be extended close to the center of the second opening 22, or a section of conduit can be set at the bottom liquid outlet of the liquid collecting barrel 72 to extend into the second opening 22.

[0040] The working principle of this utility model is as follows:

[0041] During use, the first motor 4 and the second motor 9 are first started to control the rotation of the crushing rod 5 and the auger 10, and the food waste is fed into the feed hopper 3. When feeding, the fast-rotating crushing rod 5 can be used to crush the larger volume of food waste. The crushed food waste falls into the conveying pipe 1 and is uniformly transported to the left by the rotating auger 10. The grease can pass through the filter 8 and fall into the recovery box 21. The food waste transported to the left can then fall into the separation net barrel 71 through the discharge pipe 61 and the docking pipe 65.

[0042] The auger 10 can simultaneously drive the large conical teeth 11 fixedly sleeved on the outer side of its left end to rotate synchronously, and use the small conical teeth 64 meshing with the large conical teeth 11 to drive the mounting shaft 63 and the docking tube 65 to rotate synchronously, and the docking tube 65 can drive the entire solid-liquid separation component 7 to rotate synchronously through the hook 66 on its outer wall. Since the diameter of the large conical teeth 11 is much larger than the small conical teeth 64, it is convenient to increase the rotation speed of the solid-liquid separation component 7. The centrifugal force generated by the rapid rotation can be used to throw out the grease attached to the surface of the kitchen waste and flow it into the recovery box 21 through the liquid collection barrel 72 and the second opening 22, which is convenient for subsequent unified treatment. Compared with the comparative documents, the present device can not only separate grease by gravity, but also use rotary centrifugation for solid-liquid separation, and the separation is more sufficient;

[0043] After the solid-liquid separation is completed, the first motor 4 and the second motor 9 can be turned off to put the solid-liquid separation component 7 in a stationary state. Then, the liquid collecting barrel 72 can be manually pushed to move the hanging ring 73 upward slightly, and then the hanging ring 73 can be manually rotated to completely disengage it from the hook 66. At this time, the liquid collecting barrel 72 can be moved downward again to disengage the top of the separation net barrel 71 from the docking pipe 65. The entire solid-liquid separation component 7 can be removed from the device separately, which is convenient for pouring out and cleaning the solid waste in the separation net barrel 71, and also for cleaning the solid-liquid separation component 7. Finally, the valve 24 can be opened to discharge the separated grease and other liquids to the designated location through the discharge pipe 23.

[0044] The above are only preferred specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of existing technologies should be within the scope of protection determined by the claims.
