Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically to a device for recovering grease from coarsely sorted kitchen waste. Background Technology

[0002] Food waste refers to leftover food from restaurants, canteens, and other similar establishments, as well as processing waste from fruits, vegetables, meat, oil, and pastries in the kitchen. It includes food processing scraps, leftover food, and waste cooking oil generated in households, food processing, catering services, and institutional catering activities. Food waste is characterized by high moisture content, high organic matter content, high salt content, easy decomposition and mold growth, bacterial growth, foul odor, and environmental pollution.

[0003] The grease in kitchen waste affects the life activities of microorganisms in the biological waste treatment process, reducing the treatment effect. It can also stick to the walls of the equipment and cause pipe blockage, affecting the operation of the waste treatment equipment. Therefore, it is necessary to separate the grease in the coarse sorting process. In addition to avoiding the impact on the waste treatment equipment, the waste grease can also be recycled and reused, turning waste into treasure.

[0004] Before separating grease, solid-liquid separation must be performed first. In existing technologies, the separated solid kitchen waste accumulates on the filter plate and cannot be directly discharged. It needs to be processed centrally after working for a period of time. The accumulated solid kitchen waste will affect the efficiency of solid-liquid separation. In addition, grease separation usually uses gravity method to suspend it on water before collection. This method is not easy to control the boundary between grease and water, resulting in water in the recovered grease and impurities. Utility Model Content

[0005] This invention aims to solve the aforementioned technical problems, namely, that the separated solid kitchen waste cannot be directly removed and that gravity-based grease recovery methods have limitations, by providing a device for recovering grease from coarsely sorted kitchen waste.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a food waste coarse sorting grease recovery device, including a solid-liquid separation component and an grease separation component; the solid-liquid separation component includes a box body and a cover body, the cover body having a feed inlet; the box body has an inner tank, the inner tank being funnel-shaped, with a transfer pipe at the lower end, the lower end of the transfer pipe extending into the grease separation component;

[0007] The inner tank is equipped with a filter chamber that moves within it. The bottom surface of the filter chamber is a mesh plate that slopes downwards from left to right. The cover is equipped with electric push rods on its top and near both sides. The output end of the electric push rods extends into the housing and connects to the filter chamber. The filter chamber has an output port 1 on its right side and near its lower end, and the housing has an output port 2 on its right side.

[0008] The grease separation component consists of a housing and a cover. The upper part of the cover is equipped with a motor, and the output end of the motor is equipped with a rotating rod. Several stirring rods are provided on the outside of the rotating rod. A chemical dosing port is provided on one side of the housing.

[0009] Furthermore, a splash guard is provided around the top of the filter chamber; the output end of the electric actuator is mounted on the splash guard.

[0010] Furthermore, the size and position of output port one and output port two are corresponding.

[0011] Furthermore, the transfer tube is located near the right side of box one and cover two.

[0012] Furthermore, a circular groove is provided at the lower end of the inner part of the housing, which can accommodate the rotating rod.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] During the initial solid-liquid separation, solid kitchen waste is isolated in the filter chamber. When the solid kitchen waste gradually increases and affects the separation effect, the electric push rod lifts the filter chamber upward until output port one and output port two correspond. At this time, the tilted solid kitchen waste will be directly poured into the collection device, completing the separation directly and improving efficiency.

[0015] Oil recovery is achieved through sedimentation. Reagents are added to cause the oil to flocculate into a solid, thus eliminating water content and facilitating subsequent reuse. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Example 1, in conjunction with Appendix Figure 1 , 2 A device for recovering grease from coarsely sorted kitchen waste includes a solid-liquid separation component 1 and a grease separation component 2.

[0023] The solid-liquid separation component 1 includes a housing 3 and a cover 4. The cover 4 is provided with a feed inlet 5, into which the mixture of kitchen waste is added. The housing 3 is provided with an inner tank 6, which is funnel-shaped to facilitate the transfer of the separated oil-water mixture to the grease separation component 2. The lower end of the inner tank is provided with a transfer pipe 7, which extends into the grease separation component.

[0024] Combined with appendix Figure 2 The transfer pipe 7 is located near the right side of the box body 13 and the cover body 214 to avoid affecting the operation of the motor 15 when it is in the middle.

[0025] Combined with appendix Figure 1 , 2 3. The inner tank 6 is equipped with a movable filter chamber 8. The bottom surface of the filter chamber 8 is a grid plate, which is inclined downward from left to right. The inclined shape makes it difficult for solid kitchen waste to accumulate in the same place, thus avoiding complete blockage of the grid plate. On the other hand, it can be slid out by its own gravity when it needs to be discharged.

[0026] Combined with appendix Figure 1 , 2 3. Electric push rods 9 are provided on the top of the cover 4 and near both sides. The output end of the electric push rod 9 extends into the box 3 and connects to the filter chamber 8. A splash guard 10 is provided around the top of the filter chamber 8. The output end of the electric push rod 9 is installed on the splash guard 10. The splash guard 10 provides an installation position for the electric push rod 9 and also prevents mixed waste from splashing into the inside of the box 3 when it is dumped.

[0027] The filter chamber 8 has an output port 11 on the right side and near the bottom, and the box body 3 has an output port 2 on the right side. The size and position of the output ports 11 and 2 are corresponding. In the working state, the output ports 11 and 2 are not corresponding. When solid waste needs to be discharged, the two are corresponding, so that the waste can slide out directly.

[0028] Combined with appendix Figure 1 , 24. The grease separation component 2 consists of a housing 13 and a cover 14. The upper end of the cover 14 is equipped with a motor 15, and the output end of the motor 15 is equipped with a rotating rod 16. The lower end of the housing 13 is equipped with a circular groove 18 that can accommodate the rotating rod 16. Several stirring rods 17 are provided on the outside of the rotating rod 16. A chemical addition port 19 is provided on one side of the housing 13, where chemical reagents such as aluminum salts that help flocculation can be added. The stirring rods 17 can help the oil-water mixture and chemical reagents mix, thereby improving the mixing uniformity.

[0029] The cover 14 and the box 3 can be fixedly connected or detachably connected. When fixedly connected, when it is necessary to remove the molding grease, the cover 14 and the upper box 3 and other parts need to be removed. When detachably connected, the box 3 needs to be removed first, and then the cover 14 needs to be removed.

[0030] The working principle of this utility model is as follows: Solid kitchen waste enters the first chamber 3 through the inlet 5 and is first isolated in the filter chamber 8 and stays on the grid plate. When the solid kitchen waste on the grid plate gradually increases and affects the separation effect, the electric push rod 9 lifts the filter chamber 8 upward until the first outlet 11 and the second outlet 12 correspond. At this time, the inclined grid plate will directly pour the solid kitchen waste into the external collection device, and the separation is completed directly. The oil-water mixture enters the second chamber 13 through the transfer pipe 7. Chemical reactants such as aluminum salts are added through the dosing port 19. The motor 15 drives the rotating rod 16 and the stirring rod 17 to rotate to help mix. Then it is left to stand until the oil solidifies and flocculates, and a relatively pure oil can be obtained. Since the second chamber 13 and the second cover 14 are separable, the oil can be taken out by removing the second cover 14.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
