Description
Technical Field
[0001] The utility model relates to the technical field of kitchen waste sewage treatment devices, and more specifically, it relates to a kitchen waste sewage treatment device. Background Art
[0002] In the current environmental protection technology field, the treatment of kitchen waste is an important issue. Kitchen waste contains a large amount of organic matter. If not properly treated, it will not only pollute the environment but also cause waste of resources. Although existing kitchen waste sewage treatment devices have played a certain role in treating these wastes, there are still some problems and deficiencies in actual applications.
[0003] Firstly, the structures of existing kitchen waste sewage treatment devices are usually relatively simple. Such a simple structure may not be able to effectively treat the solid debris in kitchen waste. Kitchen waste often contains a large amount of solid substances such as food residues, paper, and plastics. If not properly pretreated, these large-volume debris may block the pipelines of the treatment device, affecting the sewage treatment effect and even potentially causing the paralysis of the entire treatment system.
[0004] Secondly, when existing sewage treatment devices are in use, they usually need to be connected through various pipelines. However, the existing pipeline connection and disassembly operations are usually rather cumbersome. This is mainly because the existing pipeline connection methods may require special tools or precise alignment and adjustment. These operations not only take time but are also prone to errors. In busy dining places, such a cumbersome operation process may affect work efficiency and even the maintenance work of the equipment.
[0005] In addition, although some devices have emerged in the prior art to achieve rapid docking of pipelines, the structures of these devices are often too simple. Such a simple structure may result in unstable installation after pipeline connection, and it is easy to loosen or even fall off during the operation of the equipment. The loosening or falling off of the connection not only affects the normal treatment of sewage but may also cause sewage leakage, resulting in environmental pollution and hygiene problems.

[0038] In this embodiment, when it is necessary to connect the pipes, first rotate the adapter sleeve 20. The adapter sleeve 20 will drive the relief groove 19 to rotate. At the same time, the adapter sleeve 20 will drive the return block 16 to rotate. Then the return block 16 will drive the limit rod 15 to move. Then the limit rod 15 will move along the limit groove 17 opened on the connection block 18. At the same time, the return block 16 will cooperate with the connection block 18 to squeeze the second spring 14. When the second spring 14 is squeezed to the limit, the position of the relief groove 19 just corresponds to the positions of the limit plate 13 and the positioning plate 11. Then the tension spring 29 will pull the fitting sleeve 2 to reset along the slide rail 28 and the chute 27. Then the fitting sleeve 2 will drive the fitting plate 12 and the limit plate 13 to pass through the relief groove 19. When the tension spring 29 is completely reset, the positioning plate 11 just moves to one side of the adapter sleeve 20. Then release the adapter sleeve 20. The second spring 14 pushes the return block 16 to reset. Then the return block 16 drives the limit rod 15 and the adapter sleeve 20 to reset. Then the positions of the relief groove 19 and the positioning plate 11 no longer correspond. So that the fitting sleeve 2 is clamped on one side of the adapter sleeve 20 through the positioning plate 11 and the fitting plate 12. At this time, the outside of the adapter plate 7 loses the limit of the fitting sleeve 2. Then the first spring 5 pushes the adapter plate 7 to reset. Then the outside of the movable rod 8 loses the limit of the inside of the adapter plate 7. Then the push spring 6 pushes the movable rod 8 to reset. So that the movable rod 8 drives the clamping block 9 to reset. Then align the guide groove 26 opened on the outside of the connecting pipe 4 with the guide rail 25 arranged inside the fixed pipe 3. Then insert the connecting pipe 4 into the fixed pipe 3. When one end of the connecting pipe 4 abuts against the gasket 30, rotate the adapter sleeve 20 again. The adapter sleeve 20 drives the return block 16 and the limit rod 15 to move again. Then the limit rod 15 will slide along the limit groove 17. And the return block 16 will cooperate with the connection block 18 to squeeze the second spring 14 again. When the second spring 14 is compressed to the limit again, the positions of the relief groove 19 and the positioning plate 11 correspond. Then push the fitting sleeve 2. The fitting sleeve 2 cooperates along the slide rail 28 and the chute 27. So that the fitting sleeve 2 drives the fitting plate 12, the limit plate 13 and the positioning plate 11 to move. Then the fitting sleeve 2 will drive the tension spring 29 to stretch. Then the inner wall of the fitting sleeve 2 will squeeze the outer wall of the adapter plate 7 again. Then the adapter plate 7 will squeeze the first spring 5. Then the inner wall of the adapter plate 7 will squeeze the outside of the movable rod 8. Then the movable rod 8 will squeeze the push spring 6. Then the movable rod 8 will drive the clamping block 9 to insert into the card slot 10. Due to the slope structure design inside the card slot 10, when the clamping block 9 is completely inserted into the card slot 10, the clamping block 9 drives the connecting pipe 4 to squeeze the gasket 30 through the slope structure arranged in the card slot 10. Thus ensuring the sealing performance at the connection between the connecting pipe 4 and the fixed pipe 3. At the same time, the sealing ring 31 arranged on the outside of the connecting pipe 4 will be completely inserted into the sealing groove 32. Thus further strengthening the sealing performance at the pipe connection while realizing the rapid connection of the pipes. When the two limit plates 13 move to both sides of the adapter sleeve 20 respectively, release the adapter sleeve 20. The second spring 14 will push the return block 16 to reset.Then the return block 16 will drive the limit rod 15 and the adapter sleeve 20 to reset. Then, the mating sleeve 2 will be clamped to one side of the adapter sleeve 20 through the mating plate 12 and the limit plate 13, so that the mating sleeve 2 is stably fixed outside the fixed pipe 3, thus ensuring the rapid and stable connection of the pipeline.
[0039] Please refer to Figure 1 and Figure 2 , as an implementation of the cutting device: The cutting device includes a motor 33, a gear 34, a cutting knife 35 and a connecting shaft 36. The motor 33 is detachably installed in the processing box 1. The gears 34 are respectively connected to the output end of the motor 33 and one end of the connecting shaft 36, and the two gears 34 mesh with each other. The cutting knife 35 is installed on the connecting shaft 36, and the connecting shaft 36 is movably installed in the processing box 1.
[0040] A baffle 37 is provided in the processing box 1, and the baffle 37 is arranged below the motor 33.
[0041] More specifically, first, the waste and sewage to be processed are added to the processing box 1 through the feed port 21. Then, the motor 33 installed on the baffle 37 is turned on. Then, the motor 33 drives the gear 34 connected to one end of the connecting shaft 36 through the gear 34 connected to the output end to rotate. Then, the gear 34 drives the connecting shaft 36 to rotate. Then, the connecting shaft 36 drives each cutting knife 35 to rotate. Then, the cutting knife 35 cuts the waste with a larger volume. Then, the waste becomes smaller waste. Then, the water and oil flow into the space below the baffle 37 through the holes opened on the baffle 37. Due to the different densities of water and oil, after a period of static separation, the oil and water are separated. By turning on the heating pipe 23 to heat the processing, the solidification of grease is prevented. Then, the waste cut on the baffle 37 is extracted through the pipeline connected to the front side of the processing box 1. Then, the grease floating on the water surface is extracted through the pipelines arranged on both sides of the processing box 1. Finally, the separated sewage in the processing box 1 is extracted through the pipeline connected to the bottom end of the processing box 1, and a separator 24 is used to prevent the escape of grease.
[0042] In summary, when the overall device is in use or operation: when it is necessary to connect the pipeline, first rotate the adapter sleeve 20. The adapter sleeve 20 will drive the relief groove 19 to rotate. At the same time, the adapter sleeve 20 will drive the return block 16 to rotate. Then the return block 16 will drive the limit rod 15 to move. Then the limit rod 15 will move along the limit groove 17 opened on the connection block 18. At the same time, the return block 16 will cooperate with the connection block 18 to squeeze the second spring 14. When the second spring 14 is squeezed to the limit, the position of the relief groove 19 just corresponds to the positions of the limit plate 13 and the positioning plate 11. Then the tension spring 29 will pull the mating sleeve 2 to reset along the slide rail 28 and the chute 27. Then the mating sleeve 2 will drive the mating plate 12 and the limit plate 13 to pass through the relief groove 19. When the tension spring 29 is fully reset, the positioning plate 11 just moves to one side of the adapter sleeve 20. Then release the adapter sleeve 20. The second spring 14 pushes the return block 16 to reset. Then the return block 16 drives the limit rod 15 and the adapter sleeve 20 to reset. Then the positions of the relief groove 19 and the positioning plate 11 no longer correspond, so that the mating sleeve 2 is clamped on one side of the adapter sleeve 20 through the positioning plate 11 and the mating plate 12. At this time, the outside of the adapter plate 7 loses the limit of the mating sleeve 2. Then the first spring 5 pushes the adapter plate 7 to reset. Then the outside of the movable rod 8 loses the limit of the inner side of the adapter plate 7. Then the push spring 6 pushes the movable rod 8 to reset, so that the movable rod 8 drives the clamping block 9 to reset. Then align the guide groove 26 opened on the outside of the connecting pipe 4 with the guide rail 25 arranged on the inside of the fixed pipe 3. Then insert the connecting pipe 4 into the fixed pipe 3. When one end of the connecting pipe 4 abuts against the washer 30, rotate the adapter sleeve 20 again. The adapter sleeve 20 drives the return block 16 and the limit rod 15 to move again. Then the limit rod 15 will slide along the limit groove 17, and the return block 16 will cooperate with the connection block 18 to squeeze the second spring 14 again. When the second spring 14 is compressed to the limit again, the position of the relief groove 19 corresponds to the position of the positioning plate 11. Then push the mating sleeve 2. The mating sleeve 2 cooperates along the slide rail 28 and the chute 27, so that the mating sleeve 2 drives the mating plate 12, the limit plate 13 and the positioning plate 11 to move. Then the mating sleeve 2 will drive the tension spring 29 to stretch. Then the inner wall of the mating sleeve 2 will squeeze the outer wall of the adapter plate 7 again. Then the adapter plate 7 will squeeze the first spring 5. Then the inner wall of the adapter plate 7 will squeeze the outside of the movable rod 8. Then the movable rod 8 will squeeze the push spring 6. Then the movable rod 8 will drive the clamping block 9 to insert into the card slot 10. Due to the slope structure design inside the card slot 10, when the clamping block 9 is completely inserted into the card slot 10, the clamping block 9 drives the connecting pipe 4 to squeeze the washer 30 through the slope structure arranged in the card slot 10, thus ensuring the sealing performance at the connection between the connecting pipe 4 and the fixed pipe 3. At the same time, the sealing ring 31 arranged on the outside of the connecting pipe 4 will be completely inserted into the sealing groove 32, thus further strengthening the sealing performance at the pipeline connection while realizing the rapid connection of the pipeline. When the two limit plates 13 move to both sides of the adapter sleeve 20 respectively, release the adapter sleeve 20. The second spring 14 will push the return block 16 to reset.Then the return block 16 will drive the limit rod 15 and the adaptor sleeve 20 to reset. Then, the mating sleeve 2 will be clamped to one side of the adaptor sleeve 20 through the mating plate 12 and the limit plate 13, so that the mating sleeve 2 is stably fixed outside the fixed pipe 3, thus ensuring the rapid and stable connection of the pipeline.
[0043] First, the waste and sewage to be treated are added into the treatment tank 1 through the feed inlet 21. Then, the motor 33 installed on the baffle 37 is turned on. Then, the motor 33 drives the gear 34 connected to one end of the connecting shaft 36 to rotate through the gear 34 connected to the output end. Then, the gear 34 drives the connecting shaft 36 to rotate. Then, the connecting shaft 36 drives each cutting knife 35 to rotate. Then, the cutting knife 35 cuts the waste with a larger volume. Then, the waste becomes smaller waste. Then, the water and oil flow into the space below the baffle 37 through the holes formed in the baffle 37. Due to the different densities of water and oil, after a period of static separation, the oil and water are separated. By turning on the heating pipe 23 to heat the treatment process, the grease is prevented from solidifying. Then, the waste cut on the baffle 37 is extracted through the pipeline connected to the front side of the treatment tank 1. Then, the grease floating on the water surface is extracted through the pipelines arranged on both sides of the treatment tank 1. Finally, the separated sewage in the treatment tank 1 is extracted through the pipeline connected to the bottom end of the treatment tank 1, and the separator 24 is used to prevent the escape of grease.
