Description

Technical Field

[0001] This utility model relates to the technical field of catering waste treatment equipment, specifically a catering waste sorting device. Background Technology

[0002] Food waste sorting refers to the process of classifying food waste according to its composition through physical, mechanical, or manual means. Its core objective is to achieve resource utilization and harmless treatment, thereby reducing environmental pollution. Food waste is characterized by high water content, easy perishability, and mixed composition. Traditional landfilling or incineration easily produces leachate, odor, and greenhouse gases. Sorting technology can improve waste treatment efficiency by separating organic matter, metals, plastics, and other components. For example, organic matter can be converted into fertilizer or biogas, and metals can be recycled and reused, thereby reducing the ecological burden and promoting the development of a circular economy.

[0003] Existing food waste sorting equipment generally relies on manual screening for metal waste, which is prone to missing metal fragments due to their small size and the presence of many mixed impurities. This results in metal residues contaminating other waste, increasing recycling difficulty, and posing a risk of equipment wear and tear. In the solid-liquid separation stage, traditional equipment lacks a solid-liquid separation mechanism, making it difficult to completely separate the liquid from the high-humidity organic matter. The residue has a high water content, which not only increases transportation costs but also makes it prone to spoilage and odor. Furthermore, the separated liquid often mixes with solid residue, requiring secondary separation in subsequent processing, which is inefficient and wastes resources significantly.

The embodiments of this utility model will be described below based on its overall structure.

[0022] Reference Figures 1 to 5 In this embodiment of the utility model, a food waste sorting device includes: a feeding hopper 2 is provided on the top of the processing box 1. The feeding hopper 2 is fixed to the middle area of ​​the top cover by welding and is used to centrally pour in mixed food waste such as leftover food, plastic, metal tableware, etc. The outlet end of the feeding hopper 2 is connected to a conveyor belt 3. The conveyor belt 3 is fixed to the side of the top cover of the processing box 1 near the feeding hopper 2 by bolts. Its surface is provided with anti-slip stripes. It is driven by an external motor to uniformly transport the waste to the crushing area.

[0023] Two sets of rotating rods 4 are installed inside the processing box 1 near the feed inlet. The rotating rods 4 are rotatably connected to the side wall of the box through bearings. One end of the rotating rods 4 passes through the box and is coaxially connected to the output shaft of the first motor 5. The middle area of ​​the surface of the two sets of rotating rods 4 is fixedly connected to the crushing roller 6 through a keyway. The surface of the crushing roller 6 is provided with staggered crushing teeth. Driven by the first motor 5 to rotate in the opposite direction, it shears and crushes large pieces of organic matter and separates the adhering impurities.

[0024] The crushed waste falls onto the surface of the magnetic mesh 9. The magnetic mesh 9 is movably inserted into the inside of the processing box 1 through the insert plate 8. The insert plate 8 is welded and fixed to the side of the connecting rod 7. The two ends of the connecting rod 7 are bolted to the inner wall of the processing box 1. The magnetic mesh 9 is made of multi-layer stainless steel mesh with embedded strong magnets. It is located directly below the crushing roller 6 and can attract metal waste. Non-magnetic materials pass through the mesh and enter the subsequent processing stage. A blocking block is welded to the end of the insert plate 8 away from the box door to prevent the magnetic mesh 9 from falling off when it is pulled out.

[0025] The magnetic mesh 9 is fixedly connected to the squeezing chamber 10 below. The squeezing chamber 10 is a rectangular cavity with an open top. The back of the chamber is fixed to the pushing device 11 by the support rod bolt. The bottom of the pushing device 11 is welded to the inner wall of the processing box 1. Movable slots 12 are opened on both sides of the squeezing chamber 10. The pushing device 11 is connected to the hydraulic telescopic rod 13 on both sides by flanges. The end of the hydraulic telescopic rod 13 is fixed to the connecting arm 14 by bolt. The side of the connecting arm 14 near the movable slot 12 is welded with a pressure plate 15. The size of the pressure plate 15 matches the movable slot 12. The waste is pushed by the hydraulic telescopic rod 13 to squeeze it back and forth, forcing the residual liquid to be discharged.

[0026] A sliding strip 16 is welded to the bottom of the extrusion chamber 10. A baffle 17 is slidably inserted into the inner side of the sliding strip 16. A pusher plate 18 is welded below the baffle 17. The pusher plate 18 meshes with a gear 19. The gear 19 is connected to a second motor 20 through a coupling. The second motor 20 is bolted to the front of the extrusion chamber 10. The second motor 20 drives the gear 19 to rotate, which drives the pusher plate 18 to push the baffle 17 to slide along the sliding strip 16, realizing intermittent discharge of the residue after dewatering. A locking block is welded to the end of the sliding strip 16 away from the gear 19 to limit the maximum sliding stroke of the baffle 17.

[0027] The liquid collection tank 21 is bolted directly below the extrusion chamber 10. A fixing rod 22 is welded to the top of the liquid collection tank 21. A discharge plate 23 is welded at an angle above the fixing rod 22. Multiple sets of discharge grooves 24 are opened on the surface of the discharge plate 23 to guide the liquid into the liquid collection tank 21. A discharge port 26 is opened at the bottom of the outer side of the treatment tank 1. The size of the discharge port 26 is larger than the width of the discharge plate 23. The discharge plate 23 is inclined at an angle of 15 degrees so that the dehydrated solid residue slides into the slag collection box 25 along the inclined surface. The slag collection box 25 can be detachably installed on the outside of the treatment tank 1 for easy cleaning.

[0028] The working principle of this utility model is as follows:

[0029] Food waste enters the processing bin 1 from the feeding hopper 2 and is transported to the rotating rod 4 area by the conveyor belt 3. The first motor 5 drives the rotating rod 4 to rotate two sets of crushing rollers 6 to crush large organic objects in the waste, such as food scraps and bones, to reduce their volume and separate the sticky impurities. The crushed waste falls onto the surface of the magnetic net 9. The magnetic net 9 magnetically attracts metallic waste, while non-magnetic materials pass through the magnetic net 9 and enter the subsequent processing stage.

[0030] The crushed waste falls into the squeezing chamber 10. The pushing device 11 drives the connecting arm 14 and the pressure plate 15 to reciprocate towards the movable groove 12 through the hydraulic telescopic rods 13 on both sides, squeezing and dewatering the waste. The second motor 20 drives the gear 19 to rotate, which drives the push plate 18 to push the baffle 17 to slide along the slide bar 16, so that the dewatered residue falls onto the discharge plate 23.

[0031] The dehydrated residue falls onto the discharge plate 23, forcing the residual liquid to flow into the collection tank 21 through the discharge trough 24. The dehydrated solid waste accumulates above the baffle 17. The liquid enters the collection tank 21 through the discharge trough 24 for temporary storage and can be discharged or recycled through external pipes later. The solid residue is guided to the discharge port 26 by the inclined surface of the discharge plate 23 and is finally collected by the slag collection box 25. The metal waste adsorbed by the magnetic net 9 can be pulled out by the insert plate 8. Other unseparated impurities enter the residue treatment stage during the extrusion and dehydration process.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
