Description

Technical Field

[0001] This utility model belongs to the field of kitchen waste treatment technology, and in particular relates to a pressing and dehydration device for kitchen waste treatment. Background Technology

[0002] Food waste refers to the waste generated in daily life, food processing, catering services, and institutional catering. Food waste usually contains a lot of liquid moisture, making it prone to rotting and emitting foul odors, affecting the environment and generating a lot of bacteria. Therefore, food waste needs to be pressed and dehydrated before treatment.

[0003] A Chinese utility model patent with publication number CN219401616U discloses a pressing and dehydrating device for food waste treatment. This device uses an incomplete gear and rack mechanism to allow for repeated pressing and dehydration after the first pressing and dehydration, with the spring pulling the pressure plate up for a second cycle, enabling cyclical use and saving time and effort. However, after careful research, it was found that while the device uses an incomplete gear and rack mechanism to control the lifting and lowering of the pressure plate for pressing and dehydration, the lowest position the pressure plate can reach is constant. When the amount of waste input is small, it is difficult to achieve sufficient squeezing and dehydration, and the dehydration speed is relatively slow, affecting processing efficiency.

[0004] Therefore, there is an urgent need to improve the existing pressing and dehydration devices for food waste treatment and provide a pressing and dehydration device for food waste treatment that can dehydrate more thoroughly. Utility Model Content

[0019] As a preferred embodiment, based on the above structure, the bottom of the bottom box 1 is set in an inclined state, and a discharge port 2 is opened on its left side, and a feed port 10 is symmetrically opened on the top of the dehydration tank 7.

[0020] In this embodiment, the bottom box 1 with an inclined bottom is used to facilitate the smooth discharge of sewage and kitchen waste through the discharge port 2, making it convenient for collection and treatment.

[0021] As a preferred embodiment, based on the above structure, it further includes an isolation mechanism, which includes an annular partition 12 fixed to the inner wall of the dehydration tank 7 and located below the drive motor 5. A rubber ring 13 is bonded to the inner wall of the annular partition 12, and the rubber ring 13 rotates and seals against the outer wall of the dehydration tank 7.

[0022] In this embodiment, the isolation mechanism can intercept the ejected sewage, thus preventing it from affecting the operation of the drive motor 5.

[0023] As a preferred embodiment, based on the above structure, the outer wall of the dehydration tank 7 located below the annular partition 12 is mesh-like, and the bottom of the dehydration tank 7 is open.

[0024] In this embodiment, the mesh-like portion of the dehydration tank 7 is used to facilitate centrifugal dehydration during rotation.

[0025] As a preferred embodiment, based on the above structure, the pressing mechanism 8 further includes a reciprocating push assembly, which includes two upper conical teeth 85 with bearings mounted on the outer walls of the left and right sides of the dehydration barrel 7, and a connecting rod 86 hinged between the upper conical teeth 85 and the movable rod 82.

[0026] As a preferred embodiment, based on the above structure, both upper conical teeth 85 are further engaged with the upper conical tooth ring 4, and the hinge point between the connecting rod 86 and the upper conical teeth 85 is located at the outer edge position away from the center of the upper conical teeth 85. The movable rod 82 forms a reciprocating lifting structure through the connecting rod 86.

[0027] In this embodiment, when the dehydration tank 7 and the pressing mechanism 8 are rotated synchronously, the two upper conical teeth 85 that mesh with the upper conical tooth ring 4 can be controlled to rotate. The connecting rod 86 can push the movable rod 82, the first electric push rod 83 and the pressure plate 84 to move up and down along the vertical rod 81 at a high frequency with small amplitude, which can further press the kitchen waste.
