Technical Field

[0001] This application relates to the field of solid waste treatment equipment technology, and in particular to a kitchen waste treatment and sorting equipment. Background Technology

[0002] Food waste generated in the catering industry contains a large amount of grease and residue. Direct discharge will cause sewer blockage, waste resources, and cause environmental pollution. Various food safety issues caused by food waste have attracted much attention from society. Kitchen waste is the waste generated in residents' daily life and food processing, catering services, and unit catering activities, including discarded vegetable leaves, eggshells, tea leaves, bones, etc. To achieve efficient kitchen waste treatment, efficient sorting equipment for kitchen waste is used.

[0003] According to Chinese Patent No. CN212651942U, a kitchen waste processing and sorting device is disclosed, which relates to the field of waste processing technology. The device includes a box, with a feed pipe running through the upper left wall of the box and a feed hopper fixedly installed at the top of the feed pipe. A U-shaped groove is installed inside the upper part of the box, and a drain pipe is installed at the bottom of the U-shaped groove. In this utility model, since a roller is installed at the bottom left side of the U-shaped groove, when kitchen waste falls from the feed pipe, it will drive the roller to rotate under the action of inertia.

[0004] However, due to the gaps between the rollers in the aforementioned patents, small particles of waste, such as broken bones, can easily get stuck in these gaps. Long-term accumulation can cause the rollers to jam and become unable to transport waste. At the same time, the lack of targeted crushing and leaching separation makes it easy for waste to entangle and clog the equipment, affecting processing efficiency and equipment lifespan.

[0005] Therefore, to solve the above problems, we provide a kitchen waste processing and sorting device. Summary of the Invention

[0006] The purpose of this utility model is to provide a kitchen waste processing and sorting device to solve the problems mentioned in the background art, such as small particles of waste like broken bones easily getting stuck in the gaps between the rollers, which can cause the rollers to jam and become unable to transport waste over a long period of time. At the same time, the lack of targeted crushing and leaching separation can cause waste to easily entangle and clog the equipment.

[0007] The embodiments of this application adopt the following technical solutions: A kitchen waste sorting and processing device includes a sorting cylinder, a feeding hopper mounted on the upper surface of the sorting cylinder, a waste conveying mechanism mounted on one side of the feeding hopper, the waste conveying mechanism including a connecting rod, a plurality of hooks fixedly connected to the bottom surface of the connecting rod, a crushing mechanism installed inside the sorting cylinder, a rear conveying cylinder fixedly connected to the right side of the sorting cylinder, a conveying auger rotatably connected to the inner wall of the rear conveying cylinder via bearings, the crushing mechanism including a geared motor and two drive rollers, a plurality of crushing teeth fixedly connected to the outer surface of each drive roller, and a spur gear fixedly connected to the right end of each drive roller, the two spur gears meshing.

[0008] Preferably, both ends of each of the drive rollers are rotatably connected to the inner wall of the sorting cylinder via bearings, one end of one of the drive rollers extends to the outside of the sorting cylinder and is fixedly connected to a first sprocket, and the output end of the geared motor is connected to one end of one of the drive rollers.

[0009] Preferably, one end of the conveying auger extends to the outside of the sorting cylinder and is fixedly connected to a second sprocket. The first sprocket and the second sprocket are connected by a transmission chain, and the first sprocket is located between the reduction motor and the sorting cylinder.

[0010] Preferably, the bottom surface of the sorting cylinder is provided with equally spaced drain outlets, a waste liquid frame is provided below the sorting cylinder, and a drain pipe is installed on the front of the waste liquid frame.

[0011] Preferably, the waste conveying mechanism includes an outer shell fixedly connected to the feed hopper, a conveyor belt is provided inside the outer shell, a drive motor for driving the conveyor belt to rotate is fixedly connected to the outer surface of the outer shell, and the connecting rod and hook are located above the conveyor belt.

[0012] Preferably, the bottom surface of the waste conveying mechanism, one side of the sorting cylinder, and the bottom surface of the rear conveying cylinder are all fixedly connected to a support frame.

[0013] Preferably, the inner wall of the sorting cylinder is fixedly connected to two guide plates, which are located above the crushing teeth, and each guide plate is inclined.

[0014] Preferably, the bottom surface of the rear conveying cylinder is fixedly connected to a feeding frame, and a collection box is provided below the feeding frame.

[0015] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: 1. This kitchen waste sorting and processing equipment uses hooks in the waste conveying mechanism to separate tangled waste such as plastic bags, preventing them from wrapping around the conveyor belt. Furthermore, the meshing of the crushing teeth on the dual-drive rollers breaks large pieces of waste, such as large pieces of fruit peel and bone fragments, into smaller particles for easier subsequent processing. Through sprocket and chain drive, the crushing mechanism and the conveying auger operate synchronously, with the conveying speed matching the crushing speed. The crushed waste is promptly transported away by the conveying auger, preventing accumulation in the sorting drum. This improves processing efficiency compared to traditional equipment and prevents small particles of waste, such as bone fragments, from embedding in gaps, completely solving the problems of material jamming and equipment jamming. This facilitates normal operation of the sorting process, significantly improves the stability of continuous equipment operation, and prevents blockages.

[0016] 2. This kitchen waste sorting and processing equipment can separate waste liquids such as soup and vegetable washing water from the waste through the drain outlet of the sorting cylinder. The waste liquid flows into the waste liquid box for centralized discharge, avoiding corrosion of the internal components of the equipment. At the same time, it reduces liquid leakage pollution during subsequent waste processing, improves environmental protection, achieves waste liquid separation, protects the equipment and the environment, and effectively separates solids and liquids in kitchen waste. It also converts larger pieces of waste into smaller pieces to facilitate subsequent processing. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings. Example 1

[0021] As attached Figures 1-5 The kitchen waste sorting and processing equipment shown includes a sorting cylinder 1, a feeding hopper 2 installed on the upper surface of the sorting cylinder 1, a waste conveying mechanism 3 installed on one side of the feeding hopper 2, the waste conveying mechanism 3 including a connecting rod 34, a plurality of hooks 35 fixedly connected to the bottom surface of the connecting rod 34, a crushing mechanism 11 installed inside the sorting cylinder 1, a rear conveying cylinder 4 fixedly connected to the right side of the sorting cylinder 1, a conveying auger 16 rotatably connected to the inner wall of the rear conveying cylinder 4 through a bearing, the crushing mechanism 11 including a reduction motor 12 and two drive rollers 111, a plurality of crushing teeth 112 fixedly connected to the outer surface of each drive roller 111, and a spur gear 113 fixedly connected to the right end of each drive roller 111, the two spur gears 113 meshing with each other.

[0022] As can be seen from the above description, this utility model has the following beneficial effects: the hook 35 of the garbage conveying mechanism 3 engages with the double drive roller 111 to crush the garbage without gaps, solving the problem of material jamming in the rollers and the problem of entanglement and blockage in traditional conveying. Moreover, the conveying auger 16 realizes the continuous conveying of the crushed garbage, avoiding accumulation. When the equipment is started to process kitchen waste, the garbage moves through the conveyor belt 33 of the garbage conveying mechanism 3. The hook 35 above pushes away the entangled vegetable leaves and plastic bags. After the garbage enters the sorting cylinder 1, the crushing teeth 112 of the double drive roller 111 engage and rotate, crushing the bone fragments into small particles without particles embedding in the gaps. The crushed garbage is sent to the rear conveying cylinder 4 by the conveying auger 16, realizing a blockage-free sorting process and improving processing efficiency. Example 2

[0023] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail: As attached Figure 4 , Figure 5 As shown, in this embodiment, both ends of each drive roller 111 are rotatably connected to the inner wall of the sorting cylinder 1 via bearings. One end of one drive roller 111 extends to the outside of the sorting cylinder 1 and is fixedly connected to a first sprocket 13. The output end of the reduction motor 12 is connected to one end of one drive roller 111. One end of the conveying auger 16 extends to the outside of the sorting cylinder 1 and is fixedly connected to a second sprocket 14. The first sprocket 13 and the second sprocket 14 are connected by a drive chain 15. The first sprocket 13 is located at the position of the reduction motor. Between 12 and sorting cylinder 1; specifically, the bearings at both ends of the transmission roller 111 ensure smooth rotation and avoid waste leakage or misalignment of the crushing teeth 112 caused by the tilting of the transmission roller 111. The first sprocket 13 is directly connected to the reduction motor 12 to ensure stable crushing power. The first sprocket 13 and the second sprocket 14 are linked through the transmission chain 15 to make the crushing mechanism 11 and the conveying auger 16 run synchronously, avoiding waste accumulation caused by fast crushing and slow conveying. Synchronous transmission reduces the complexity of independent control of equipment components and reduces the difficulty of operation.

[0024] As attached Figure 2 , Figure 4 As shown, in this embodiment, the bottom surface of the sorting cylinder 1 is provided with equidistantly arranged drain outlets 9, a waste liquid frame 7 is provided below the sorting cylinder 1, and a drain pipe 8 is installed on the front of the waste liquid frame 7. The waste conveying mechanism 3 includes an outer shell 31 fixedly connected to the feed hopper 2. A conveyor belt 33 is provided inside the outer shell 31, and a drive motor 32 for driving the conveyor belt 33 to rotate is fixedly connected to the outer surface of the outer shell 31. The connecting rod 34 and the hook 35 are located above the conveyor belt 33. Specifically, the drain outlets 9 separate waste liquid such as leftover soup and vegetable washing water from the waste, avoiding the waste liquid from soaking the transmission components such as bearings and chains, which would cause corrosion. The waste liquid frame 7 collects the waste liquid in a concentrated manner, which can be uniformly processed later. The conveyor belt 33 provides a stable waste conveying path, replacing the traditional roller, without gaps. The drive motor 32 controls the conveying speed. The connecting rod 34 and the hook 35 are located above the conveyor belt 33, such as to clear away the accumulated and tangled waste, ensuring that there is no local accumulation on the surface of the conveyor belt 33.

[0025] As attached Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, in this embodiment, a support frame 10 is fixedly connected to the bottom surface of the waste conveying mechanism 3, one side of the sorting cylinder 1, and the bottom surface of the rear conveying cylinder 4. Two guide plates 17 are fixedly connected to the inner wall of the sorting cylinder 1. The guide plates 17 are located above the crushing teeth 112, and each guide plate 17 is inclined. A feeding frame 5 is fixedly connected to the bottom surface of the rear conveying cylinder 4, and a collection box 6 is provided below the feeding frame 5. Specifically, the support frame 10 connects the waste conveying mechanism 3, the sorting cylinder 1, and the rear conveying cylinder 4 to form a stable overall structure, preventing the equipment from being damaged by vibration during operation. The components are repositioned, and the frame is raised to facilitate the placement of the waste liquid frame 7 and collection box 6 below, saving space and making it easy to pick up and put down. The inclined guide plate 17 guides the conveyed waste to fall accurately between the double drive rollers 111. The inclined angle design of 30°-45° uses gravity to assist the waste to fall, reducing the residue of waste on the guide plate 17 and avoiding the situation of residual waste deterioration and odor. After the feeding frame 5 guides the crushed waste in the conveying cylinder 4, it falls accurately into the collection box 6. The collection box 6 can be quickly replaced. When the box is full, it can be directly replaced with an empty box, which is suitable for batch processing scenarios and does not require stopping the machine to dump the waste.

[0026] Working principle: When using, first confirm that the conveyor belt 33 of the garbage conveying mechanism 3 rotates smoothly, the hook 35 is not broken, the double drive roller 111 of the crushing mechanism 11 meshes normally, the crushing teeth 112 are not worn, and the conveying auger 16 rotates flexibly; the waste liquid frame 7 and the collection box 6 are placed in place without deviation, and the valve of the drain pipe 8 is closed. Kitchen waste is fed into the waste conveying mechanism 3, and the drive motor 32 is started simultaneously. The conveyor belt 33 moves the waste, and the hook 35 above separates the tangled waste such as vegetable leaves, ensuring that the waste is evenly distributed on the conveyor belt 33. The waste falls into the feed hopper 2 and sorting cylinder 1 with the end of the conveyor belt 33, and is guided by the inclined guide plate 17 to accurately enter between the double drive rollers 111. At the same time, the geared motor 12 is started to drive the double transmission roller 111 to rotate. Under the meshing transmission action of the spur gear 113, the transmission roller 111 rotates, and the crushing teeth 112 mesh and crush the garbage, breaking large pieces of garbage into small particles. Simultaneously, the first sprocket 13 drives the second sprocket 14 through the transmission chain 15, and the conveying auger 16 rotates synchronously. During the crushing process, waste liquids such as soup and water in the waste flow into the waste liquid frame 7 below through the drain outlet 9 on the bottom of the sorting cylinder 1, achieving solid-liquid separation. The crushed waste falls to the bottom of the sorting cylinder 1 and is pushed to the rear conveying cylinder 4 by the conveying auger 16. It then moves along the inner wall of the rear conveying cylinder 4 to the unloading frame 5. Throughout the entire operation, there was no feeding blockage. Both the material conveying and the connection between each link were extremely smooth, ensuring the smooth progress of the sorting process. The processed waste falls into the collection box 6 below through the unloading frame 5. Once the collection box 6 is full, it can be confirmed by observation. The equipment is then turned off, the full box is removed and replaced with an empty box, and the equipment is restarted to continue processing. Finally, after processing is completed, the drain pipe 8 valve is opened to discharge the waste liquid in the waste liquid frame 7.
