Description

Technical Field

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

[0002] Kitchen waste, generated from daily life, food processing, catering services, and workplace meals, typically contains extremely high levels of moisture and organic matter, making it easily perishable and producing a foul odor. With proper treatment and processing, it can be transformed into new resources. Its high organic content allows it to be used as fertilizer or animal feed after rigorous processing, and it can also produce biogas for fuel or power generation. The oil and fat components can be used to prepare biofuels.

[0003] Patent application CN117732842A discloses a kitchen waste treatment device, comprising: a shell, a cover, a holding bin, a heat storage and drying component, a crushing component, a fresh air filtration component, and a control component; the shell has an internal receiving space and a receiving portion for placing the holding bin; the heat storage and drying component, the crushing component, the fresh air filtration component, and the control component are respectively installed in the receiving space; the cover is hinged to the top of the shell and covers the opening of the holding bin; the holding bin is used to hold kitchen waste, and a rotatable crushing component is installed at the bottom of the holding bin; the heat storage and drying component includes a heating element and a blowing system, wherein the heating element... Located at the bottom or side of the holding container, it is used to heat the food waste inside the container; the air outlet of the blowing system is located on the cover and corresponds to the opening end, and is used to blow and dry the heated food waste; the food waste in the holding container is first heated and dried by the heat storage drying component, so that the wet food waste has a certain hardness (air-drying hardening), and then the rotating crushing component crushes or pulverizes the food waste. During this process, the gas generated during processing is filtered by the fresh air filtration component to reduce air pollution to the use environment. After cooling treatment is completed, the final product is hardened food waste with less moisture (light weight) and smaller volume.

[0004] However, the following problems still exist when using this solution: food waste accumulates in layers inside the equipment and cannot be effectively turned over. On the one hand, the accumulation of waste causes uneven heat transfer, and local areas may experience overheating or incomplete treatment, affecting the overall treatment effect. On the other hand, the moisture inside the accumulated food waste is blocked by the outer material, making it difficult for water vapor to escape quickly and fully, which prolongs the drying time and increases energy consumption.

[0030] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] like Figures 1 to 10 As shown, the kitchen waste treatment device of the present invention includes a housing 10, a cylinder 20, a blade assembly 30, a turning assembly 40, a transmission assembly 50, a discharge assembly 60, and a condensing filter box 70. The cylinder 20 and the condensing filter box 70 are both disposed inside the housing 10. The inner cylinder 21 heats and dries the kitchen waste, causing the moisture in the kitchen waste to be removed. The condensing filter box 70 filters, adsorbs, and condenses the removed hot air. The blade assembly 30 is disposed inside the cylinder 20 and is used to cut and crush the kitchen waste during drying. The turning assembly 40, in cooperation with the transmission assembly 50, can turn the kitchen waste up and down and stir and loosen it, so that the water vapor mixed in the kitchen waste can be quickly removed, so that the blade assembly 30 can crush the kitchen waste, making the equipment more efficient in processing kitchen waste. In addition, the turning assembly 40, in cooperation with the discharge assembly 60, can discharge the processed kitchen waste.

[0032] refer to Figure 1 , Figure 2 as well as Figure 3 The top of the box 10 is provided with an openable cover plate 11, and a feed box 12 is fixedly installed on the cover plate 11. The feed box 12 is provided with a crushing component 13, which consists of two crushing rollers. A drive box is provided on one side of the crushing rollers, which can drive the two crushing rollers to rotate in opposite directions, thereby crushing the kitchen waste entering the feed box 12 and reducing the volume of the kitchen waste.

[0033] refer to Figure 3 and Figure 4 The cylinder 20 includes an inner cylinder 21 and an outer cylinder 22. The inner cylinder 21 is composed of a vertical part and a conical part. The vertical part is located directly below the feed box 12 so that the kitchen waste in the feed box 12 can enter the inner cylinder 21. The outer cylinder 22 is coaxially sleeved on the outside of the inner cylinder 21 and fixed to the box body 10. A heating component 23 is provided between the inner cylinder 21 and the outer cylinder 22 to heat the inner cylinder 21 so that the moisture contained in the kitchen waste in the inner cylinder 21 can be quickly evaporated and removed. The heating component 23 is specifically a heating plate. A top frame 24 is fixedly installed on the inner cylinder 21.

[0034] A positioning cylinder 221 is fixedly installed inside the outer cylinder 22, and a positioning rod 211 is fixedly installed on the inner cylinder 21 and inserted into the positioning cylinder 221. By limiting the positioning rod 211 through the positioning cylinder 221, the inner cylinder 21 is limited to the inside of the outer cylinder 22, so that the inner cylinder 21 will not rotate or move laterally inside the outer cylinder 22.

[0035] refer to Figure 3 , Figure 4 as well as Figure 9 The blade assembly 30 includes a blade holder 31, a mounting cylinder 32, and a cutter 33. The blade holder 31 is coaxially rotatably mounted inside the conical part of the inner cylinder 21. The mounting cylinder 32 is coaxially fixed on the blade holder 31. The cutter 33 is fixedly mounted on the outer wall of the mounting cylinder 32 and is inclined along the slope of the conical part. By rotating the blade holder 31, the mounting cylinder 32 drives the cutter 33 to rotate in the inner cylinder 21, cutting and crushing the kitchen waste that has accumulated in the conical part, reducing the particle size of the kitchen waste, allowing the moisture to be removed more quickly, and improving the drying efficiency.

[0036] The bottom of the outer cylinder 22 is rotatably fitted with a shaft 222, and the bottom end of the shaft 222 is provided with a first motor located inside the housing 10 to drive the shaft 222 to rotate. The bottom of the blade holder 31 is provided with a slot 311, and the shaft 222 is inserted into the slot 311. When the shaft 222 rotates, it can drive the blade holder 31 to rotate, thereby causing the cutter 33 to cut and pulverize the kitchen waste.

[0037] refer to Figure 3 , Figure 4 as well as Figure 10 The material-turning assembly 40 includes a vertical cylinder 41 and an auger conveyor shaft 42. The vertical cylinder 41 is coaxially disposed inside the inner cylinder 21, and its bottom end extends and is rotatably mounted inside the mounting cylinder 32. The auger conveyor shaft 42 is coaxially disposed inside the vertical cylinder 41, with its top end rotatably mounted on the top frame 24 and its bottom end rotatably mounted inside the vertical cylinder 41. A second motor is installed on the cover plate 11 to drive the auger conveyor shaft 42 to rotate in the vertical cylinder 41, pushing the kitchen waste entering the vertical cylinder 41 upward to complete the material-turning process. Furthermore, the auger conveyor shaft 42, when rotating, can be activated by the transmission assembly 50. The vertical cylinder 41 is rotated in the opposite direction, which stirs the kitchen waste tumbling up and down in the inner cylinder 21 and cleans the kitchen waste adhering to the cylinder wall. This allows the kitchen waste to be fully loosened, and the moisture trapped between the kitchen waste can be released more quickly and efficiently as the kitchen waste is turned over, improving the drying efficiency. In turn, the cutting blade 33 can cut and crush the kitchen waste more efficiently and thoroughly. At the same time, it prevents the kitchen waste from sticking to the inner wall of the inner cylinder 21 as the moisture is released, thus increasing the service life of the equipment and reducing the difficulty of cleaning the equipment.

[0038] refer to Figure 5A bracket 111 is rotatably mounted on the cover plate 11, and the bracket 111 is located at the output end of the second motor. The bottom of the bracket 111 has a polygonal slot. The top of the auger conveyor shaft 42 is provided with a protruding shaft 421 that is compatible with the slot. When the cover plate 11 is closed, the protruding shaft 421 can be inserted into the slot of the bracket 111, so that the second motor can drive the bracket 111 to rotate and drive the auger conveyor shaft 42 to rotate, thereby facilitating the turning of kitchen waste. When the cover plate 11 is opened, the bracket 111 can be separated from the protruding shaft 421, and the inner cylinder 21 can be pulled out from the outer cylinder 22 for cleaning and maintenance of the inner cylinder 21.

[0039] refer to Figure 3 , Figure 7 , Figure 8 as well as Figure 10 The outer wall of the vertical cylinder 41 is provided with a stirring rack 43 and a cleaning plate 44, so that when the vertical cylinder 41 rotates, the stirring rack 43 can stir the kitchen waste, and the cleaning plate 44 can scrape and clean the kitchen waste adhering to the inner wall of the inner cylinder 21.

[0040] refer to Figure 10 The upper notch 411 and the lower notch 412 are respectively provided on the side walls at the upper and lower ends of the vertical cylinder 41, so that the kitchen waste in the conical part can enter the vertical cylinder 41 through the lower notch 412, and then be lifted in the vertical cylinder 41 by the conveyor shaft 42, and finally discharged to the vertical part through the upper notch 411, thereby completing the up-and-down turning of the kitchen waste in the inner cylinder 21.

[0041] refer to Figure 6 , Figure 7 as well as Figure 8 An annular platform 212 is coaxially arranged inside the inner cylinder 21. An annular groove 213 is opened at the bottom of the annular platform 212. A ring sleeve 413 is fixedly installed on the outside of the vertical cylinder 41. A support rod 414 is fixedly installed on the ring sleeve 413. A limiting shaft 415 is fixedly fixed on the support rod 414 and slidably assembled in the annular groove 213. By sliding the limiting shaft 415 in the annular groove 213, the support rod 414 and the ring sleeve 413 provide stable support for the vertical cylinder 41, ensuring the stability of the vertical cylinder 41 during rotation. The cleaning plate 44 is vertically fixed on the support rod 414 and is set close to the inner wall of the inner cylinder 21, so that the vertical cylinder 41 can drive the cleaning plate 44 to rotate and complete the cleaning of kitchen waste on the inner wall of the inner cylinder 21.

[0042] refer to Figure 5 as well as Figure 10The transmission assembly 50 includes a sleeve 51, a driving bevel gear 52, a driven bevel gear 53, and a transmission bevel gear 54. The sleeve 51 is coaxially fixed to the top of the vertical cylinder 41. The top of the auger conveyor shaft 42 passes through and is rotatably mounted inside the sleeve 51. The driving bevel gear 52 is coaxially fixed to the auger conveyor shaft 42. The driven bevel gear 53 is coaxially fixed to the sleeve 51 and is arranged opposite to the driving bevel gear 52. The transmission bevel gear 54 is rotatably mounted on the top frame 24 and meshes with the driving bevel gear 52 and the driven bevel gear 53. When the auger conveyor shaft 42 rotates, the driving bevel gear 52 pushes the transmission bevel gear 54 to rotate, so that the transmission bevel gear 54 pushes the driven bevel gear 53 to rotate in the opposite direction relative to the driving bevel gear 52. This causes the sleeve 51 to rotate in the opposite direction relative to the auger conveyor shaft 42, thereby causing the mixing rack 43 to rotate in the inner cylinder 21 and agitate the kitchen waste.

[0043] refer to Figure 3 , Figure 5 as well as Figure 7 The discharge assembly 60 includes a discharge cylinder 61, a movable pipe 62, and a fixed pipe 63. The discharge cylinder 61 is coaxially sleeved on the top of the vertical cylinder 41 and can be raised and lowered relative to the vertical cylinder 41. Lowering it closes the upper notch 411, and raising it opens the upper notch 411. The movable pipe 62 is inclinedly fixed to the discharge cylinder 61 and connected to it, so that after the discharge cylinder 61 lowers to close the upper notch 411, the kitchen waste transported from the vertical cylinder 41 to the upper notch 411 can enter the movable pipe 62. The fixed pipe 63 is inclinedly fixed to the housing 1. The movable tube 62 is adapted to the inner cylinder 21. One end of the fixed tube 63 is connected to the inside of the inner cylinder 21, and the other end extends to the outside of the box 10. The movable tube 62 can be connected to the fixed tube 63 when the discharge cylinder 61 descends, so that the kitchen waste entering the movable tube 62 can be discharged to the outside of the box 10 along the fixed tube 63, thus completing the recycling of kitchen waste. An electric push rod 621 is installed on the movable tube 62 and mounted on the top frame 24, which can push the movable tube 62 to rise and fall in the inner cylinder 21, so that the discharge cylinder 61 rises and falls outside the vertical cylinder 41.

[0044] refer to Figure 3 The condenser filter box 70 is connected to the inner cylinder 21 through the connecting pipe 71. The condenser filter box 70 is equipped with an exhaust fan and a condenser. The exhaust fan can extract the evaporated water vapor, which is then condensed into liquid by the condenser. An activated carbon filter box is installed between the exhaust fan and the condenser to adsorb and filter the gas, so that the discharged gas will not produce any odor.

[0045] Working principle: Drained kitchen waste is fed into the feed hopper 12, where the crushing component 13 first crushes the waste to reduce its volume, and then it enters the inner cylinder 21 of the cylinder 20. The heating plate between the inner cylinder 21 and the outer cylinder 22 heats the inner cylinder 21, causing the moisture in the kitchen waste to evaporate into water vapor.

[0046] The first motor drives the insert shaft 222 to rotate, which in turn drives the blade holder 31 and the cutter 33 of the blade assembly 30 to rotate, cutting and pulverizing the kitchen waste accumulated in the conical part of the inner cylinder 21. This reduces the particle size of the kitchen waste and further promotes the removal of internal moisture.

[0047] The second motor drives the auger conveyor shaft 42 to rotate. On one hand, the auger conveyor shaft 42 lifts the kitchen waste at the bottom of the inner cylinder 21 through the lower notch 412 of the vertical cylinder 41 to the upper notch 411 for discharge, realizing the up-and-down circulation and tumbling of the kitchen waste. On the other hand, the auger conveyor shaft 42 drives the vertical cylinder 41 to rotate slowly in the opposite direction through the transmission assembly 50 (composed of a driving bevel gear 52, a driven bevel gear 53, and a transmission bevel gear 54), which in turn drives the stirring rack 43 and the cleaning plate 44 on it to rotate. The stirring rack 43 stirs and loosens the kitchen waste, while the cleaning plate 44 scrapes off the kitchen waste adhering to the inner wall of the inner cylinder 21, ensuring that all kitchen waste is heated evenly and that moisture escapes quickly.

[0048] Moisture and odorous gases generated during the drying process are drawn into the condensation filter box 70 through the connecting pipe 71 for filtration and condensation. After the kitchen waste is processed, the discharge assembly 60 is activated. The electric push rod 621 pushes the movable pipe 62 down, causing the discharge cylinder 61 to block the upper notch 411 of the vertical cylinder 41. At the same time, the movable pipe 62 connects with the fixed pipe 63. The continuously rotating auger conveyor shaft 42 lifts the processed and dried kitchen waste from the bottom, discharges it into the discharge cylinder 61 through the upper notch 411, and then discharges it outside the box 10 through the movable pipe 62 and the fixed pipe 63, completing the collection.

[0049] In this invention, the turning component 40 forcibly turns and loosens the kitchen waste, completely breaking up its accumulation and allowing internal moisture to escape quickly and fully, significantly shortening the drying time. Simultaneously, the blade assembly 30 cuts and pulverizes the kitchen waste during drying, reducing particle size and further accelerating moisture evaporation. The synergistic effect of these two components significantly improves overall processing efficiency. The cleaning plate 44 continuously scrapes the inner wall of the inner cylinder 21 during the turning process, effectively preventing the kitchen waste from scorching and sticking to the wall due to dehydration, ensuring stable equipment operation and reducing subsequent cleaning difficulties. Furthermore, the stirring of the mixing rack 43 and the turning of the auger conveyor shaft 42 ensure that the kitchen waste is properly handled. Uniform heating avoids localized overheating or inadequate processing, resulting in a more evenly dried kitchen waste output. The inner cylinder 21 is securely installed by engaging with the positioning cylinder 221 of the outer cylinder 22 via the positioning rod 211, preventing rotation or displacement of the inner cylinder 21 during operation. Furthermore, the auger conveyor shaft 42 and the drive motor are connected by a plug-in connection between the clamp 111 and the convex shaft 421, allowing the entire inner cylinder 21 to be pulled out from the outer cylinder 22 after opening the cover plate 11. This not only efficiently processes kitchen waste but also facilitates cleaning and maintenance of the equipment. The discharge assembly 60 can be raised and lowered to switch between working and discharge states, allowing for continuous production without stopping the machine.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
