Description

Technical Field

[0001] The present invention relates to the technical field of kitchen waste treatment, and particularly to a solid-liquid separation device for kitchen waste. Background Art

[0002] With the acceleration of the urbanization process and the improvement of residents' living standards, the generation amount of kitchen waste is increasing day by day. This kind of waste has a complex composition, containing not only a large amount of organic solid substances, but also sewage and oil stains. If not properly treated, it will not only cause environmental pollution, but also lead to waste of resources. Therefore, efficient kitchen waste treatment technologies, especially those for realizing solid-liquid separation and oil stain recycling, have become key topics that need to be urgently broken through in the current environmental protection field.

[0003] At present, the traditional technologies for solid-liquid separation and oil stain recycling in kitchen waste treatment are relatively backward, and there is a serious lack of systematic treatment equipment. In the existing treatment process, the links such as solid-liquid separation and oil stain separation are often separated, lacking unified integrated design, and it is impossible to achieve efficient connection between each step. For example, in the solid-liquid separation link, most adopt the method of filter screen filtration, that is, by pouring kitchen waste on the filter screen and relying on gravity to make the liquid seep naturally, and the solid residue remains on the surface of the filter screen. This method has extremely low separation efficiency, is difficult to achieve large-scale and continuous treatment, and has frequent manual operations and high labor intensity; after the solid-liquid separation is completed, the oil stain separation stage generally relies on manual use of spoons or other simple tools to scoop up the oil stains from the surface layer of the separated liquid. Due to the lack of precise stratification control means, a large amount of sewage will inevitably be mixed in the scooping process, resulting in low purity of oil stain collection and poor recycling rate. At the same time, the existing equipment is not specially designed for low-temperature environments. Once the environmental temperature drops, the oil stains are easy to condense on the inner wall of the filter screen or container, and the fluidity becomes significantly worse, making the subsequent separation operations more difficult. In addition, traditional equipment usually does not have an internal cleaning structure. After long-term use, the filter screen and other components are extremely easy to adhere to stubborn oil stains and solid residues. Manual cleaning not only takes time and effort, but also is difficult to completely remove, and is easy to breed bacteria, causing secondary pollution, seriously affecting the service life and treatment effect of the equipment. The decentralized treatment of each link and the single function of the equipment make the entire kitchen waste treatment process inefficient and costly, and it is difficult to meet the needs of modern environmental protection and resource recycling.

[0004] Based on this, a solid-liquid separation device for kitchen waste is proposed. Summary of the Invention

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-8 , the present invention provides a technical solution: A solid-liquid separation device for kitchen waste includes a box body 1, a conveyor bin 2 and a box door 3 are connected to the box body 1. The upper end of the conveyor bin 2 is in an open state and can be used for the input of kitchen waste. The structure of the box door 3 can be opened to place a plastic bucket 9. The lower end of the conveyor bin 2 is connected to a feeding chute 13. The cross-section of the feeding chute 13 is square, and the structure of the feeding chute 13 is an inclined device, which is convenient for the separated liquid to move along the feeding chute 13. A semi-circular filter screen 8 is connected to the feeding chute 13. The separated liquid can pass through the semi-circular filter screen 8 and drip onto the feeding chute 13. A screw 7 is arranged above the semi-circular filter screen 8. The semi-circular filter screen 8 and the screw 7 are on the same axis. As the screw 7 rotates, the garbage can be conveyed from bottom to top. The semi-circular filter screen 8 is fixedly connected to the feeding chute 13. The semi-circular filter screen 8 is arranged below the screw 7. The screw 7 is rotatably connected to the feeding chute 13. One end of the screw 7 is connected to a driving member for driving the screw 7 to rotate. One end of the feeding chute 13 is connected to a delivery pipe 17. The delivery pipe 17 is arranged above the treatment box 11; Inside the box body 1, there is a processing box 11 connected. An opening pipe 31 is connected to the processing box 11. One end of the opening pipe 31 is connected to a collecting pipe 12. Both the opening pipe 31 and the collecting pipe 12 can rotate. When rotating, only the deflection bar 29 needs to be pulled. Below one end of the collecting pipe 12, there is a plastic bucket 9. The oil stain discharged from the collecting pipe 12 can automatically flow into the plastic bucket 9. Inside the processing box 11, there is a long pipe 35 connected. The lower end of the long pipe 35 penetrates through the processing box 11 and communicates with the sewage storage bin 28. The upper end of the long pipe 35 is connected to a sewage box 30. The upper end of the long pipe 35 and the bottom surface of the sewage box 30 are on the same horizontal plane. A short pipe 36 is connected to the sewage box 30. The upper end of the short pipe 36 is higher than the bottom surface of the sewage box 30, and the lower end of the short pipe 36 is lower than the lower end of the partition plate 32. The lower end of the processing box 11 is connected to a sewage storage bin 28. A sewage pipe 6 is connected to the sewage storage bin 28. One end of the sewage pipe 6 extends out of the box body 1, and the other end extends into the sewage storage bin 28. A sealing pipe 39 is connected to the extending part. A water inlet pipe 4 is connected to the processing box 11. One end of the water inlet pipe 4 extends out of the box body 1 and is connected to the tap water pipeline. A small water heater is arranged at the connection part, so that the water conveyed into the water inlet pipe 4 is hot water. One end of the water inlet pipe 4 is connected to a three-way pipe 21. One end of the three-way pipe 21 is connected to a water injection pipe 37 through an electromagnetic valve 25. The opening of the water injection pipe 37 is related to the detection of the travel switch 24. When it is detected that the water level height in the processing box 11 drops, at this time, the electromagnetic valve 25 connected to one end of the water injection pipe 37 opens, so that water is injected into the processing box 11 through the water injection pipe 37. The other end of the three-way pipe 21 is connected to a cleaning mechanism for cleaning the processing box 11.

[0020] Specifically, as Figure 3 shown, the driving part includes a motor 16. The output end of the motor 16 is interconnected with one end of a screw rod 7 through a chain 15. After the device is started, it is necessary to wait until the water level height in the processing box 11 rises to the standard height before the motor 16 starts to operate. The motor 16 can stably drive the screw rod 7 to rotate through the cooperation of the chain 15, so as to complete the conveying of garbage.

[0021] Specifically, as Figure 3 shown, one end of a conveying pipe 17 is connected to a sealing plate 18 through a bolt 19. A groove is opened on the sealing plate 18. The position of the adjustable bolt 19 connected to the groove can be adjusted, so as to adjust the area of the sealing plate 18 blocking one end of the conveying pipe 17, thereby adjusting the sewage conveying efficiency. The structure of the sealing plate 18 is fixed by the bolt 19. The bolt 19 can clamp the sealing plate 18 on the conveying pipe 17.

[0022] Specifically, as Figure 5As shown, a deflection bar 29 is connected to the outside of the collecting pipe 12, and an arc frame 27 is connected to the outside of the processing box 11. The deflection bar 29 is slidably connected to the arc frame 27. The height of the opening of the open tube 31 can be changed by moving the deflection bar 29, so as to realize the collection of oil pollution on the sewage. Different heights affect the oil pollution collection purity of the sewage in the processing box 11. When the height is lower, the probability of water in the sewage entering the collecting pipe 12 is increased, that is, the deflection angle of the deflection bar 29 needs to be adjusted when the equipment is actually used, so as to realize high-precision separation of oil pollution.

[0023] Specifically, Figure 3 and Figure 7 As shown, the cleaning mechanism includes a spray gun 5, a three-way pipe 21 is connected to a three-way pipe 23 through a connecting pipe 22, the spray gun 5 is connected to one end of the three-way pipe 23, the spray gun 5 needs to be inserted into the cleaning window 14 on one side of the discharge chute 13 for cleaning operations, a sealing tube 39 is connected to the sewage pipe 6, the upper end of the sealing tube 39 is connected to the processing box 11, the upper end of the sealing tube 39 passes through the processing box 11 and is connected to the processing box 11, a T-type plug 34 is arranged above the sealing tube 39, the upper end of the T-type plug 34 is connected to the electric push rod 26, when the electric push rod 26 moves downward, the T-type plug 34 can be used to complete the sealing of the sewage pipe 6, and the electric push rod 26 is connected to the inner wall of the processing box 11.

[0024] Specifically, Figure 8 As shown, partitions 32 are connected to the inside of the processing box 11, and the partitions 32 are alternately and equidistantly connected to the inner wall of the processing box 11. This type of partition 32 setting structure can guide the oil and dirt into the open pipe 31, improve the oil and dirt separation efficiency, increase the oil and dirt movement range, and ensure orderly oil and dirt separation.

[0025] Specifically, Figure 7 and Figure 8 As shown, a travel switch 24 is connected to the inner wall of the treatment box 11, and a float 33 is connected to the travel switch 24. The float 33 can understand the change of the liquid level in the treatment box 11 through the change of buoyancy. A sleeve 38 is slidably sleeved on the short tube 36, and the sleeve 38 structure can adjust the sewage discharge height of the upper end of the short tube 36. Since the oil content of different kitchen wastes is different, that is, the oily sewage with a large oil content is more likely to enter the short tube 36, it is necessary to increase the height of the sleeve 38 to prevent the oil from entering the long tube 35. On the contrary, the height of the adjustable sleeve 38 is lowered. Since the oil content entering the short tube 36 is less, the treatment cycle of the oil in the sewage box 30 is longer, and there is no need to frequently clean the oil in the sewage box 30. A heating rod 20 is connected to the treatment box 11, and the sewage temperature in the treatment box 11 is maintained by the heating rod 20 to prevent problems such as oil condensation.

[0026] Specifically, Figure 2 and Figure 3As shown in the figure, one end of the tee pipe two 23 is connected to the flushing pipe 10, the other end of the flushing pipe 10 passes through the conveying bin 2 and is connected to the shower head seat 40. The shower head seat 40 is arranged directly above one end of the screw 7. A cleaning window 14 is rotatably connected to the outside of the blanking chute 13. When the equipment is running, the flushing pipe 10 is always in a running state, and a valve can also be set at the connection between the tee pipe two 23 and the flushing pipe 10 to control the running state of the flushing pipe 10. Hot water is conveyed into the shower head seat 40 through the flushing pipe 10 to wash the oil stains attached to the surface of the garbage, thereby improving the separation efficiency.

[0027] To sum up, for a kitchen waste solid-liquid separation device provided in this embodiment, when kitchen waste needs to be processed, the waste can be put on the conveying bin 2. Driven by the screw 7, the waste can move from bottom to top. A collection bucket for collecting solid waste can be placed on one side of the device. At this time, the solid waste can be effectively collected, and the sewage containing oil stains can pass through the semi-circular filter screen 8 and enter the blanking chute 13. The shower head seat 40 located above the higher end of the screw 7 can wash the waste during the solid-liquid separation process by spraying water, effectively removing the oil stains carried on the surface of the waste. The shower head seat 40 is fixedly connected to the conveying bin 2, and the screw 7, the semi-circular filter screen 8 and the blanking chute 13 are all arranged in an inclined state.

[0028] The sewage flowing along the blanking chute 13 can enter the conveying pipe 17 connected to the tail end. One end of the conveying pipe 17 is slidably connected with a sealing plate 18. The opening size of the tail end of the conveying pipe 17 can be controlled by adjusting the position of the sealing plate 18, so as to adjust the flow rate of the sewage entering the treatment tank 11. After the adjustment is completed, the structure of the sealing plate 18 is fixed by relying on the bolt 19.

[0029] A certain amount of tap water is pre-stored in the treatment tank 11, and the tap water enters through the water inlet pipe 4 and is injected into the box body 1 from the water injection pipe 37. The lower end of the partition plate 32 is not connected to the bottom surface of the treatment tank 11, and the water level of the stored certain amount of tap water is higher than the lowest end height of the partition plate 32. The float ball 33 arranged in the treatment tank 11 can cooperate with the travel switch 24 to detect the liquid level height in real time according to the change of its own pressure. When it is found that the liquid level height becomes low, that is, when the sewage discharged into the treatment tank 11 is not enough to support the liquid level to maintain the original height, the solenoid valve 25 can inject tap water into the treatment tank 11 through the water injection pipe 37 to maintain the liquid level height.

[0030] When the equipment is running, at this time, the flushing pipe 10 can always convey tap water into the shower head seat 40, that is, the water in the tee pipe one 21 and the tee pipe two 23 is always in a flowing state. In order to improve the flushing effect and avoid the temperature drop of the sewage in the treatment tank 11, a small water heater needs to be connected to the water inlet pipe 4 to effectively wash the oil stains on the surface of the garbage and prevent the problem of oil stain condensation caused by injecting cold water into the treatment tank 11.

[0031] To ensure the temperature balance of the sewage in the treatment tank 11 and avoid the situation where hot water cannot be continuously injected into the treatment tank 11 when the sewage liquid level is balanced, the temperature of the sewage in the treatment tank 11 will drop. Therefore, a heating rod 20 structure is set up, which can detect the temperature of the sewage in the treatment tank 11 in real time. When the sewage temperature is low, the heating rod 20 can be automatically started to heat the sewage to avoid oil fouling condensation.

[0032] The sewage entering the treatment tank 11 from one end of the delivery pipe 17 is composed of water and oil. The water can quickly dissolve into the tap water pre-placed in the treatment tank 11, while the oil floats on the water surface. The accumulated oil can flow along the "S"-shaped circuit composed of the partition plate 32 to the opening pipe 31. Since the oil floats on the water surface, by adjusting the opening height of the opening pipe 31 at this time, the oil can enter the opening pipe 31 and flow into the plastic bucket 9 from the collection pipe 12. The opening height of the opening pipe 31 can be adjusted by rotation. The oil flowing into the plastic bucket 9 can be well collected, greatly improving the purity of the oil and facilitating subsequent refining and processing.

[0033] To ensure the dynamic balance of the sewage liquid level in the treatment tank 11, a sewage discharge structure is also set up. The sewage can enter the sewage discharge tank 30 from the short pipe 36, and then the sewage enters the sewage discharge bin 28 from the long pipe 35. To prevent the oil in the sewage from not floating up in time under the drive of the water flow and being discharged from the sewage discharge tank 30, a sleeve 38 is connected to the upper end of the short pipe 36 in the sewage discharge tank 30. When the height of the upper end of the sleeve 38 from the upper end of the sewage discharge tank 30 is closer to the lower end of the sewage discharge tank 30, the oil in the sewage flowing out from the upper end of the short pipe 36 can more easily float to the upper liquid level of the sewage discharge tank 30 and will not continue to flow along the water flow into the long pipe 35, thereby further reducing the oil content of the sewage discharged to the outside. The sewage entering the sewage discharge bin 28 can enter the sewage discharge pipe 6, and then the sewage discharge is completed. By setting up a sealing pipe 39 and a T-shaped plug 34 structure, when the T-shaped plug 34 moves down, it can pass through the sealing pipe 39 to seal the sewage discharge pipe 6. Thus, by controlling the lowering height of the T-shaped plug 34, the sewage discharge efficiency of the sewage discharge pipe 6 can be adjusted. When the equipment is running, the upper end of the sealing pipe 39 is in a closed state.

[0034] Under normal conditions, the height of the upper end of the sewage discharge tank 30 is higher than the liquid level height in the treatment tank 11. Since the oil collected on the liquid surface of the sewage discharge tank 30 will accumulate more and more as the equipment runs, at this time, water can be injected into the treatment tank 11 and the opening pipe 31 can be rotated to increase the opening height to avoid sewage directly entering the collection pipe 12. The T-shaped plug 34 is adjusted so that the sewage discharge pipe 6 is closed. At this time, the sewage can directly enter the sewage discharge tank 30, so that the stored oil can be released into the treatment tank 11, and then each structure is reset to continue the separation of the sewage.

[0035] When the device needs to be cleaned, stop putting garbage into the device, open the cleaning window 14, and align one end of the spray gun 5 with the opening at the cleaning window 14. Use the spray gun 5 to wash the blanking chute 13. At this time, the height of the T-shaped plug 34 moves up, so that the upper end of the sealing pipe 39 is opened. At this time, the sewage generated by cleaning can enter the treatment tank 11 and be directly discharged into the sewage pipe 6 from the sealing pipe 39, improving the cleaning efficiency.

[0036] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
