Description

Technical Field

[0001] This invention relates to the field of waste treatment, specifically to a device for recycling kitchen waste. Background Technology

[0002] The amount of food waste generated is gradually increasing. Currently, food waste is mainly treated by mixing it with household waste, compressing it, and then landfilling it. This method not only pollutes the environment but also wastes resources. Generally, food waste contains a lot of sewage, and oily food waste contains a lot of waste oil. During transportation and treatment, it is easy to cause secondary pollution by the leakage of swill. The water content of food waste is about 60%-80%. During the treatment process, it is not only a useless resource but also increases transportation and labor costs. Therefore, it is necessary to dehydrate and deoil food waste. A processor with publication number CN211169964U that can separate oil and water from catering waste has been found.

[0003] However, in the above technologies, spraying is required during the water-oil separation process when the equipment processes kitchen waste, which wastes water resources and can easily lead to poor water-oil separation effect. Summary of the Invention

[0004] The problem this invention aims to solve is to crush the waste before dehydration.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is a kitchen waste recycling device, comprising a support frame, a crusher, and a water-oil separation structure. The support frame includes a support base and a support arm, with the support arm perpendicularly arranged to the support base. The crusher includes a housing, a drive motor, and two toothed rollers arranged side-by-side within the housing, rotating in opposite directions. The toothed rollers are provided with teeth, which are staggered. Each toothed roller is provided with a central shaft, which penetrates the side wall of the housing and is subsequently fitted with a transmission gear. The two transmission gears are a driving gear and a driven gear, respectively. The wheel is also connected to a transmission assembly; the water-oil separation structure includes a water-storing outer layer and an inner tank. A lifting valve is installed at the bottom of the inner tank. The lifting valve includes a sealing baffle, a lifting rod, and a telescopic cylinder. There is a waste channel inside the lifting rod. The upper end of the lifting rod is connected to the bottom wall of the sealing baffle through three support rods. There is a gap between adjacent support rods. The lower end of the lifting rod is connected to a waste valve. A discharge port is provided on the bottom wall of the waste valve. The discharge port of the waste valve is connected to the waste channel. There is a receiving space between the water-storing outer layer and the inner tank. A wettable copper mesh is also installed in the receiving space. The super-wetting copper mesh is inclined and installed above the bottom surface of the water-storing outer layer.

[0006] Specifically, the driving gear and the driven gear are meshed together. The driving gear and the driven gear have the same module, but the diameter and number of teeth of the driving gear are twice that of the driven gear. This results in a difference in the rotational speed of the two gear rollers, allowing them to run asynchronously and forming a fast and slow roller.

[0007] Specifically, both the inner tank and the outer water storage layer are cylindrical structures. The inner tank has filter holes on its side walls, the bottom of the inner tank is a concave spherical surface, and the bottom surface of the outer water storage layer is an inclined surface. An outlet is located at the lowest point of the bottom surface of the outer water storage layer.

[0008] Specifically, a circular through hole is provided on the bottom surface of the inner tank, and a sleeve is connected to the circular through hole. The lower end of the sleeve is connected to the bottom wall of the outer water layer, and the lifting rod is set inside the sleeve.

[0009] Specifically, the sealing baffle is set at the upper end of the lifting rod. Both the upper and lower surfaces of the sealing baffle are convex. The bottom surface of the sealing baffle can fit against the bottom surface of the inner liner. A sealing gasket is set at the bottom of the sealing baffle, and a sealing ring that matches the sealing gasket is set on the circular through hole.

[0010] Specifically, an oil drain port is provided on the side wall of the outer layer of the water storage layer, and the oil drain port is located at the lowest point of the super-wettable copper mesh.

[0011] Specifically, the waste valve is equipped with a piston ring, which is annular, and a top pressure plate that can cooperate with the piston ring is provided at the bottom of the lifting rod. A limit collar is provided outside the top pressure plate and the piston ring.

[0012] Specifically, a load-bearing partition is provided on the support arm, and the load-bearing partition is connected to the side wall of the support arm. A gear ring is provided at the upper end of the inner liner after passing through the load-bearing partition, and a bearing is provided between the gear ring and the load-bearing partition. The gear ring is meshed with the transmission assembly, and the gear ring is connected to the driven gear through the transmission assembly. The gear ring and the driven gear have the same module.

[0013] Specifically, the transmission assembly includes a bevel gear, a transmission rod, and a speed-increasing gear. The bevel gear meshes with the driven gear. The module of both the bevel gear rod and the speed-increasing gear is the same as that of the driven gear. The transmission rod is located between the bevel gear and the speed-increasing gear. The speed-increasing gear meshes with the gear ring. The diameter and number of teeth of the bevel gear are smaller than those of the driven gear, while the diameter and number of teeth of the speed-increasing gear are larger than those of the gear ring.

[0014] Specifically, the box is a rectangular box with positioning blocks on the side wall and positioning grooves at the upper end of the support arm, allowing the positioning blocks to be inserted into the positioning grooves.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: by rotating two toothed rollers in opposite directions, the kitchen waste is crushed and then the water-oil mixture is thrown out into the receiving space through the inner liner. Then, the water-oil mixture is separated by the ultra-wet copper mesh in the receiving space. The remaining kitchen waste in the inner liner can be discharged through the waste channel and discharge port in the lifting rod. The equipment is simple to operate, unloading is more convenient, and the water-oil separation effect is better. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to an electrical connection; they can refer to a hydraulic connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] See Figure 1 , Figure 3As shown, a kitchen waste recycling device includes a support frame, a crusher, and a water-oil separation structure. The support frame includes a support base 101 and a support arm 201. The support arm 201 is perpendicular to the support base 101 and connected to the crusher. The crusher includes a housing 301, a drive motor 401, and toothed rollers 501. The housing 301 is rectangular, and a positioning block 601 is provided on the side wall of the housing 301. A positioning groove 602 is provided at the upper end of the support arm 201, allowing the positioning block 601 to be inserted into the positioning groove 602. There are two toothed rollers 501, which are arranged side by side in the housing 301 and rotate towards each other. The toothed rollers 501 have teeth that are interlocked and mesh with each other during rotation. Each toothed roller 501 has a central shaft located at the axis of the toothed roller 501. A central shaft passes through the side wall of the housing 301 and is equipped with transmission gears. The two transmission gears are a power gear 701 and a driven gear 801, which are meshed together. The power gear 701 and the driven gear 801 have the same module, but the diameter and number of teeth of the power gear 701 are twice that of the driven gear 801. This results in a difference in the rotational speed of the two toothed rollers 501, allowing them to operate asynchronously and forming a fast and slow roller. This avoids material blockage and entanglement and improves the tearing and cutting capabilities of the toothed rollers 501, enabling them to better crush the material. The output shaft of the drive motor 401 is connected to the power gear 701. When the drive motor 401 is running, the output shaft controls the rotation of the power gear 701, which in turn rotates the driven gear 801, causing the two toothed rollers 501 to operate simultaneously and crush the kitchen waste that falls into the housing 301.

[0030] See Figures 7-9As shown, the water-oil separation structure includes a water-storing outer layer 901 and an inner liner 1000. Both the inner liner 1000 and the water-storing outer layer 901 are cylindrical barrel-shaped structures. A receiving space 1010 exists between the water-storing outer layer 901 and the inner liner 1000. A filter hole 1001 is provided on the side wall of the inner liner 1000, allowing liquid in the inner liner 1000 to drain from the filter hole 1001 into the receiving space 1010. A wettable copper mesh 1011 is also provided within the receiving space 1010. The super-wettable copper mesh 1011 is inclined and positioned above the bottom surface of the water-storing outer layer 901, and an oil drain port 1020 is located at the lowest point of the super-wettable copper mesh 1011. The water storage outer layer 901 is installed on the side wall, and the bottom surface of the water storage outer layer 901 is also an inclined surface. According to the principle of slope towards the drainage point, an outlet 1030 is set at the lowest point of the inclined surface. The liquid in the containing space 1010 can be discharged from the outlet 1030. The bottom of the inner liner 1000 is a concave spherical surface. A circular through hole is set at the bottom of the inner liner 1000. A sleeve 1040 is connected to the circular through hole. The lower end of the sleeve 1040 is connected to the bottom wall of the water storage outer layer 901, so that the inner liner 1000 can be directly connected to the outside through the sleeve 1040. A lifting valve is set in the sleeve 1040. Waste in the inner liner 1000 can be discharged through the lifting valve.

[0031] See Figure 5 , Figure 6 , Figure 8As shown, the lifting valve includes a sealing baffle 1050, a lifting rod 1051, and a telescopic cylinder 1052. The sealing baffle 1050 is located at the top of the lifting rod 1051. Both the upper and lower surfaces of the sealing baffle 1050 are convex. The bottom surface of the sealing baffle 1050 can fit against the bottom surface of the inner liner 1000. A sealing gasket is provided at the bottom of the sealing baffle 1050, and a sealing ring that mates with the sealing gasket is provided on the circular through hole. The sealing effect is improved by the sealing gasket and the sealing ring. The lifting rod 1051 is cylindrical. A waste channel 1053 is provided inside the lifting rod 1051. Three support rods are provided at the upper end of the lifting rod 1051. The lower end of the support rods is connected to the top wall of the lifting rod 1051, and the upper end of the support rods is connected to... On the bottom surface of the sealing baffle 1050, there is a gap between each support rod, allowing the crushed kitchen waste to enter the waste channel 1053 through the inner liner 1000. A waste valve 1060 is connected to the lower end of the lifting rod 1051. The bottom wall of the waste valve 1060 is provided with a discharge port 1093, which can communicate with the waste channel 1053. A piston ring 1061 is provided on the waste valve 1060. The piston ring 1061 is annular and has a rubber layer on the outside. A top pressure plate 1063 that can cooperate with the piston ring 1061 is provided at the bottom of the lifting rod 1051. Limiting devices are provided on the outside of the top pressure plate 1063 and the piston ring 1061. When piston ring 1061 is inserted into limiting collar 1062, piston ring 1061 pushes top pressure plate 1063 upward. When the top of top pressure plate 1063 contacts the top wall of limiting collar 1062, the rubber layer of piston ring 1061 contacts the rubber layer of limiting collar 1062, forming a seal at the connection between piston ring 1061 and top pressure plate 1063, preventing food waste from leaking out from the connection. After the waste enters the inner liner 1000, the waste valve 1060 is lowered by telescopic cylinder 1052, causing piston ring 1061 to separate from top pressure plate 1063. At this time, top pressure plate 1063 can rotate within limiting collar 1062, ensuring that waste valve 1060 does not affect lifting rod 1051. When the inner liner 1000 rotates, the sealing baffle 1052 is tightly fitted to the inner liner 1000. Therefore, the sealing baffle 1052 drives the top pressure plate 1063 to rotate within the limiting collar 1062, preventing the water-oil mixture from flowing out of the waste channel 1053 below the sealing baffle 1052 before being thrown out of the inner liner. The waste valve 1060 is connected to the telescopic end of the telescopic cylinder 1052, and the fixed end of the telescopic cylinder 1052 is connected to the bottom wall of the water storage outer layer 901. When the telescopic cylinder 1052 retracts, the lifting rod 1051 can drive the sealing baffle 1050 to rise within the inner liner 1000. When the telescopic cylinder 1052 extends, the lifting rod 1051 can drive the sealing baffle 1050 to fall.

[0032] See Figures 2-4As shown, a load-bearing partition 1070 is provided on the support arm 201, and the load-bearing partition 1070 is connected to the side wall of the support arm 201. The upper end of the inner liner 1000 passes through the load-bearing partition 1070, and a gear ring 1080 is provided at the upper end of the inner liner 1000. The gear ring 1080 can drive the inner liner 1000 to rotate. The gear ring 1080 is meshed with a speed-changing assembly, which includes a bevel gear 1090, a transmission rod 1091, and a speed-increasing gear 1092. Gear 1090 meshes with driven gear 801. Transmission rod 1091 is positioned between bevel gear 1090 and speed-increasing gear 1092. Transmission rod 1091 drives speed-increasing gear 1092 to rotate via the rotation of bevel gear 1090. Speed-increasing gear 1092 meshes with ring gear 1080. The diameter and number of teeth of bevel gear 1090 are smaller than those of driven gear 801, while the diameter and number of teeth of speed-increasing gear 1092 are larger than those of ring gear 1080, thus driving the motor. When the drive gear 701 and the electrically driven gear 801 rotate, the inner tank 1000 can be controlled to rotate at high speed through the speed change assembly. A bearing is provided at the lower end of the gear ring 1080, and the lower end of the bearing is connected to the upper end of the load-bearing partition 1070 to avoid excessive friction between the gear ring 1080 and the load-bearing partition 1070 when they rotate. The lower end of the load-bearing partition 1070 is connected to the top wall of the water storage outer layer 901, so that the water storage outer layer 901 is suspended on the load-bearing partition 1070. The upper end of the load-bearing partition 1070 is also connected to a protective shell, which is installed on the toothed ring 1080 to protect the toothed ring 1080 and prevent foreign objects from falling in. A square-round connector 1081 is provided between the inner liner 1000 of the toothed ring 1080 and the crusher housing 301. The square-round connector 1081 has a structure with a rectangular opening at the top and a circular opening at the bottom, so that the crushed material in the housing 301 can enter the inner liner 1000 through the square-round connector for water-oil separation treatment.

[0033] In application of this invention, the positioning block 601 of the crusher is first inserted into the positioning groove 602 of the support arm 201. Then, a guide pipe such as a hose is connected to the outlet 1030, and the other end of the guide pipe is inserted into the sewer. An oil collection box is placed below the discharge port 1093. Then, the drive motor 401 is started, and the kitchen waste is poured into the crusher's housing 301. After entering the housing 301, the kitchen waste is crushed by the toothed rollers 501. Since the two toothed rollers 501 are fast and slow rollers, they also tear and shear the kitchen waste during crushing to prevent strips from wrapping around the toothed rollers 501 or sticky waste from sticking to the toothed rollers 501, thus reducing the amount of waste on the toothed rollers 501. The residue is removed, thus improving the continuous working time and efficiency of the crusher. After being crushed by the toothed roller 501, the kitchen waste enters the inner liner 1000 through the square-round joint 1081 below the box 301. The toothed ring 1080 at the upper end of the inner liner 1000 is driven by the speed-increasing component and the driven gear 801, thereby causing the inner liner 1000 to rotate at high speed, thus separating the kitchen waste in the inner liner 1000 into solid, water, and oil phases. The solid kitchen waste is thrown to the side wall of the inner liner 1000 due to centrifugal force, while the wastewater and waste oil in the kitchen waste are thrown out from the filter holes 1001 of the inner liner 1000 to the containment space 1010 between the outer water storage layer 901 and the inner liner 1000, and the water and oil are separated. The waste then flows down the side wall of the containing space 1010 to the bottom of the outer water layer 901. Because the bottom of the outer water layer 901 is a sloping super-wetting copper mesh 1011, the super-hydrophilic material of the mesh allows water to pass through quickly while blocking oil. Therefore, wastewater passes through the mesh while the waste oil is blocked. After passing through the mesh, the wastewater falls to the bottom of the outer water layer 901. Since the outer water layer 901 is also sloping, the wastewater can be discharged from the lowest outlet 1030 and then drained into the sewer through a conduit. The waste oil from the kitchen waste is disposed of after the wastewater is drained. Open the oil drain port 1020. Since the oil drain port 1020 is located at the lowest point of the super-wettable copper mesh 1011, the waste oil will slowly flow out from the oil drain port 1020. After the water and oil are separated, the waste valve 1060 is raised by the telescopic cylinder 1052. When the piston ring 1061 of the waste valve 1060 contacts the limiting sleeve 1062, the piston ring 1061 pushes the limiting sleeve 1062 to rise, so that the lifting rod 1051 drives the sealing baffle 1050 to rise, so that the kitchen waste in the inner tank 1000 falls into the waste channel 1053 through the gap between the support rods and is discharged from the discharge port 1093. The single motor is used as the power source, which saves costs and the equipment is easy to operate and unload.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
