Description

Technical Field

[0001] This application relates to the technical field of waste collection and treatment equipment, and in particular to a kitchen waste collection and treatment device. Background Technology

[0002] With the improvement of people's living standards, the amount of food waste generated is increasing day by day. Food waste mainly includes organic waste generated in the catering service industry, household kitchens, food processing, and food distribution, such as leftover food, food scraps, wastewater from washing pots and dishes, and fruit peels and scraps. It is characterized by high water content, high oil content, high salt content, and easy rotting and foul odor. If not disposed of properly, it can easily cause great harm to the environment.

[0003] Currently, common methods of food waste disposal have many problems. In some places, food waste is directly dumped into garbage bins and then transported to landfills for disposal. This method is not only highly polluting and occupies a lot of land resources, but also easily produces odors. There is also the practice of grinding and crushing food waste and discharging it directly into the sewer, but this is easy to clog the sewer and increase the burden on the city's sewer network. In addition, some existing food waste treatment devices have problems such as poor filtration effect and inconvenient cleaning. For example, in solid-liquid-oil-water separators, the screen cannot effectively distinguish food waste of different sizes when it vibrates, and the screen mesh is easy to clog. The residue in the channel is prone to deterioration and will also result in larger residue particles entering the oil-water separator, which is not conducive to oil-water separation.

[0021] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0022] This application discloses a kitchen waste collection and processing device. For example... Figure 1 , Figure 2 As shown, the device includes an outer shell 1, with a discharge pipe 3 at the lower end of the outer shell 1. One end of the discharge pipe 3 is connected to an external sewer pipe. Before connecting the discharge pipe 3 to the sewer, an electromagnetic valve is installed, which is linked to the device's operating status. The valve is only opened during the processing stage and closed at other times to prevent backflow of sewer odors. An exhaust pipe 4 is installed at the upper part of the outer shell 1. An activated carbon filter box is installed in the middle section of the exhaust pipe 4, which is filled with a composite filter material of granular activated carbon and molecular sieve. The exhaust pipe 4 is connected to an external exhaust fan.

[0023] See Figure 2 , Figure 5 As shown, a collection tank 5 is installed inside the outer casing 1. The inner wall of the collection tank 5 can be made of food-grade stainless steel, and the surface is electrolytically polished to reduce the adhesion rate of oil stains. The collection tank 5 is provided with a through hole 6, and a filter screen 7 is installed in the through hole 6. A base plate 8 is provided below the collection tank 5. A drive source 9 is provided between the base plate 8 and the outer casing 1. The drive source 9 is a servo motor, which achieves precise rotation control through a PLC control system. It uses a combination of centrifugal force and gravity to improve the liquid filtration efficiency. A torque sensor and a sealing ring are installed at the connection between the motor output shaft and the base plate 8. When there is too much residue in the collection tank 5 and the load exceeds the set threshold, a shutdown alarm is automatically triggered to avoid motor overload damage. In addition, a wear-resistant copper ring can be embedded in the contact edge between the base plate 8 and the outer casing 1 to reduce friction loss during rotation. The surface of the copper ring is coated with high-temperature grease.

[0024] See Figure 2 , Figure 3 , Figure 5As shown, a fixing component 1 is provided between the base plate 8 and the collection bucket 5. The fixing component 1 includes a fixing bolt 12. One end of the fixing bolt 12 is set with a hexagonal head to facilitate tool operation. The fixing bolt 12 is threaded to the base plate 8. The collection bucket 5 at the corresponding position of the fixing bolt 12 is provided with a fixing hole. The fixing bolt 12 is inserted into the fixing hole on the collection bucket 5.

[0025] A positioning rod 13 is installed on the outside of the collection bucket 5. A positioning groove 14 is provided on the upper end of the bottom plate 8 at the corresponding position of the positioning rod 13. The positioning rod 13 contacts the positioning groove 14. A cover plate 10 is provided on the top of the collection bucket 5. A ring of nitrile rubber sealing gasket is pasted on the lower end face of the cover plate 10. The cross-section is dovetail-shaped and matches the sealing groove on the upper end face of the collection bucket 5. When the cover plate 10 is closed, a reliable seal is formed.

[0026] See Figure 2 , Figure 3 , Figure 4 As shown, a fixing component two is provided between the cover plate 10 and the collection bucket 5. The fixing component two includes a buckle 11 and an insert block 18. The buckle 11 is installed between the cover plate 10 and the collection bucket 5. The insert block 18 is installed on the lower end face of the cover plate 10. A slot 19 is provided on the upper end of the collection bucket 5 at the corresponding position of the insert block 18. The insert block 18 is inserted into the slot 19. A collar 15 is rotatably installed on the upper end of the cover plate 10. The collar 15 is fitted onto the feed pipe 2.

[0027] The upper end of the collar 15 is fixedly connected to the inner top wall of the outer shell 1 by a telescopic rod 16. The telescopic rod 16 is a chrome-plated hollow piston rod with a built-in dust cover to prevent oil stains from kitchen waste from entering the rod and affecting the telescopic performance. A tension spring 17 is fitted on the telescopic rod 16. One end of the tension spring 17 is fixedly connected to the collar 15, and the other end of the tension spring 17 is fixedly connected to the outer shell 1. A feed pipe 2 is provided at the upper end of the outer shell 1, and the feed pipe 2 is slidably set with the cover plate 10.

[0028] The implementation principle of a kitchen waste collection and treatment device according to an embodiment of this application is as follows: During the waste collection stage, kitchen waste enters the device through the feed pipe 2 set at the upper end of the outer shell 1 and enters the collection bin 5. The collection bin 5 is provided with a through hole 6, and a filter screen 7 is installed in the through hole 6. At this time, the filter screen 7 will perform preliminary filtration on the kitchen waste entering the collection bin 5, which can intercept some larger residues and prevent them from being mixed into the subsequent processing stage.

[0029] When further processing or cleaning of the waste in collection bin 5 is required, the drive source 9 between the base plate 8 and the outer shell 1 starts to work. The drive source 9 drives the base plate 8 to rotate. Since the collection bin 5 and the base plate 8 are fixedly connected, the collection bin 5 will also rotate accordingly. The lower end of the outer shell 1 is provided with a discharge pipe 3. One end of the discharge pipe 3 is connected to an external sewer pipe, which can discharge the treated liquid into the sewer in a reasonable manner, avoiding direct discharge into the sewer and causing blockage. The upper part of the outer shell 1 is provided with an exhaust pipe 4, which is connected to an external exhaust fan. It can extract the odor emitted by the waste, preventing the odor from accumulating in the device and the surrounding environment, reducing the burden on the urban sewer network, and avoiding the problems of occupying a large amount of land resources and generating odors, as with direct burial.

[0030] When the collection bin 5 needs to be disassembled and cleaned, first disconnect the connection between fixing component one and fixing component two, unscrew the fixing bolt 12, open the buckle 11, etc. At this time, the fixing of the cover plate 10 is released. Then the tension spring 17 drives the collar 15 to move upward, and the collar 15 drives the cover plate 10 to move accordingly, thereby avoiding the influence of the cover plate 10 when disassembling the collection bin 5. Then the collection bin 5 can be taken out of the device, which makes it convenient to clean the residue accumulated in the collection bin 5 and on the filter screen 7, preventing the residue from accumulating and deteriorating. This solves the problem of poor filtration effect and inconvenient cleaning in some existing kitchen waste treatment devices, and helps to improve the overall kitchen waste treatment efficiency. After cleaning, the collection bin 5 is put back into the device according to the above fixing steps to continue the collection and treatment of kitchen waste.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
