Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, specifically to a solid-liquid separation device for catering waste. Background Technology

[0002] Food waste, as a significant component of urban solid waste, is increasing in volume due to the booming development of the catering industry and the continuous improvement of people's living standards. Food waste is characterized by high water content, rich organic matter, and easy decomposition. If not treated promptly and effectively, it will not only emit foul odors and breed large amounts of bacteria and pests, causing serious pollution to the surrounding environment, but may also lead to the spread of diseases and threaten public health. Therefore, the proper treatment and resource utilization of food waste is of great practical significance. Solid-liquid separation, as a key step in food waste treatment, directly affects the efficiency and cost of subsequent treatment processes.

[0003] Currently, most food waste solid-liquid separation equipment on the market is based on the principle of mechanical extrusion to achieve solid-liquid separation. The basic workflow involves transporting the collected food waste into a specific extrusion chamber, where pressure is applied to the waste through a pressure plate, squeezing out the liquid and achieving initial separation of solids and liquids. This method can reduce the volume and weight of food waste to some extent, lowering the difficulty and cost of subsequent processing.

[0004] However, existing solid-liquid separation equipment for food waste has many problems in practical applications. Regarding the compression method, currently, a single pressure plate is generally used to compress the waste. This design greatly limits the amount of waste that can be separated into solid and liquid phases each time. Due to the limited compression area of ​​a single pressure plate, multiple operations are required when processing large amounts of food waste, which not only increases processing time but also reduces efficiency. Furthermore, when the pressure plate compresses the waste, the uneven distribution of waste within the compression chamber and the varying pressure transmission between the pressure plate and the waste result in different compression levels at different locations. In some locations, the waste may experience greater pressure and be fully compressed, allowing for more thorough liquid separation; however, in other locations, the pressure is less, resulting in insufficient compression and a large amount of liquid remaining in the solid waste, leading to incomplete solid-liquid separation. Summary of the Invention

[0005] The purpose of this invention is to provide a solid-liquid separation device for catering waste, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a solid-liquid separation device for food waste, comprising a crusher, a solid-liquid separation tank, and a filter plate.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6This invention provides a solid-liquid separation device for food waste, comprising a crusher 1, a solid-liquid separation tank 2, and a filter plate 9. The crusher 1 is used to crush the food waste, and the crushed food waste directly enters the solid-liquid separation tank 2. The filter plate 9 is horizontally arranged and installed in the solid-liquid separation tank 2. The filter plate 9 is removable for easy cleaning. A pressure roller 15 is provided in the solid-liquid separation tank 2 to squeeze the food waste, causing the liquid to be squeezed out. The solid-liquid separation tank 2 is also provided with a multi-functional blade 13 for pushing or pushing out the food waste. A horizontal pushing component is installed on the solid-liquid separation tank 2 to drive a moving seat 3 horizontally. The moving seat 3 is located directly above the solid-liquid separation tank 2. A hydraulic cylinder 4 is installed on the moving seat 3, and a lifting plate 11 is installed on the telescopic end of the hydraulic cylinder 4. The pressure roller 15 is installed on the lifting plate 11. The lifting plate 11 is provided with a vertical through groove 17. The multi-functional blade 13 is slidably connected to the inner wall of the through groove 17. The side of the lifting plate 11 is provided with a transverse groove 19, which passes through the through groove 17. An L-shaped plate 12 is slidably connected in the transverse groove 19, with the vertical part of the L-shaped plate 12 located outside the transverse groove 19. A vertical plate 8 is fixedly connected to the crusher 1. A bend plate 14 is connected to the side of the vertical plate 8. The bend plate 14 is used to make the L-shaped plate 12 contract or extend. An electromagnet 20 is embedded in the inner wall of the through groove 17. The multi-functional blade 13 is made of a ferromagnetic material, such as iron. The multi-functional blade 13 is vertically set. When the electromagnet 20 is energized, the electromagnet 20 will attract the multi-functional blade 13, preventing it from moving.

[0025] Please see Figures 1 to 7 In this embodiment of the invention, limiting grooves 18 are provided at both ends of the through groove 17. The limiting grooves 18 extend directly to the top surface of the lifting plate 11, but do not extend to the bottom surface of the lifting plate 11. Limiting blocks 22 are connected to both ends of the multifunctional blade 13, and the limiting blocks 22 are slidably engaged with the limiting grooves 18. In this way, the multifunctional blade 13 will not detach downward from the through groove 17.

[0026] In this embodiment of the invention, the horizontal pushing assembly includes a rotary motor 7 and a threaded shaft 6. The rotary motor 7 is fixedly mounted on a vertical plate 8, and its output shaft is coaxially and fixedly connected to the threaded shaft 6. The movable seat 3 is provided with a threaded hole and a guide through hole. A guide shaft 5 is slidably connected to the guide through hole, and the guide shaft 5 is fixedly connected to the vertical plate 8. The threaded shaft 6 is connected to the threaded hole. Thus, when the rotary motor 7 is started, the threaded shaft 6 will rotate, and under the combined action of the guide shaft 5, the movable seat 3 will move horizontally.

[0027] In this embodiment of the invention, a plurality of elastic telescopic rods 21 are installed on the bottom surface of the lifting plate 11, and the pressure roller 15 is mounted on the mounting frame 16, the top surface of the mounting frame 16 being connected to the end of the elastic telescopic rods 21. Thus, the pressure roller 15 can adaptively adjust its height when compressing food waste.

[0028] In this embodiment of the invention, the crusher 1 is fixedly installed on one side of the solid-liquid separation tank 2, and a sealing door 10 is provided on the other side of the solid-liquid separation tank 2. A drain pipe is provided at the bottom of the solid-liquid separation tank 2. The liquid food can be discharged through the drain pipe, and the solid food can be discharged by opening the sealing door 10.

[0029] In this embodiment of the invention, when the multi-functional blade 13 is at the lower end of its stroke, the limiting block 22 contacts the bottom of the limiting groove 18, the top surface of the multi-functional blade 13 contacts the bottom surface of the L-shaped plate 12, and the lower end of the multi-functional blade 13 is lower than the lower end of the pressure roller 15. At this time, the multi-functional blade 13 is an actuating element.

[0030] In this embodiment of the invention, the elastic telescopic rod 21 is composed of a guide sleeve and a telescopic shaft. A return spring is provided inside the guide sleeve. The upper end of the guide sleeve is fixedly connected to the bottom surface of the lifting plate 11. The side of the telescopic shaft is slidably connected to the inner wall of the guide sleeve. The lower end of the telescopic shaft is connected to the mounting bracket 16. The upper end of the telescopic shaft is connected to the bottom surface of the lifting plate 11 through the return spring.

[0031] The working process of this embodiment is as follows: During use, food waste is transported to the crusher 1, which crushes the waste and then transports it to one side of the solid-liquid separation tank 2. At this time, the electromagnet 20 is de-energized, causing the multi-functional blade 13 to be at its lowest point. The L-shaped plate 12 is retracted via the angle plate 14, and the top surface of the multi-functional blade 13 contacts the bottom surface of the L-shaped plate 12, preventing it from moving upwards. This allows the multi-functional blade 13 to flatten the waste on one side of the solid-liquid separation tank 2, spreading it evenly on the filter plate 9. Next, the angle plate 14 extends the L-shaped plate 12 outwards, preventing it from restricting the upward movement of the multi-functional blade 13. This causes the lifting plate 11 to move downwards, and the multi-functional blade 13 moves upwards relative to the lifting plate 11. When the lower end of the multi-functional blade 13 is higher than the lower end of the pressure roller 15, the electromagnet 20 is energized, fixing the multi-functional blade 13. At this point, the pressure roller 15 is used to squeeze the spread waste, achieving solid-liquid separation. After solid-liquid separation is completed, the multi-functional blade 13 is positioned at the lowest point of its stroke again, and the lifting plate 11 is moved downwards. The lower end of the multi-functional blade 13 contacts the surface of the filter plate 9, opening the sealing door 10. This allows the multi-functional blade 13 to push the waste towards the sealing door 10, and the solid waste is pushed out.
