Description

Technical Field

[0001] This disclosure relates to the field of kitchen waste treatment technology, and in particular to a solid-liquid-oil separation device for kitchen waste. Background Technology

[0002] Food waste is a common type of waste in daily life. It contains extremely high levels of moisture and organic matter, making it easily perishable and producing a foul odor. With proper treatment and processing, food waste can be transformed into new resources. Its high organic matter content allows it to be used as fertilizer or animal feed after strict processing. It can also produce biogas for fuel or power generation, while the oil and grease components can be used to produce biofuels.

[0003] Patent No. 2023213611582 discloses a food waste treatment device, including a solid-liquid separation mechanism and a cleaning mechanism. The solid-liquid separation mechanism is used to separate the food waste into solid and liquid components, and the cleaning mechanism is connected to the solid-liquid separation mechanism. The solid-liquid separation mechanism includes a separation tank with an inlet and an outlet, the inlet being lower than the outlet. The cleaning mechanism includes a first spray assembly connected to the separation tank, used to spray liquid onto the inlet. The food waste treatment device of this application includes a solid-liquid separation mechanism capable of separating food waste into solid and liquid components; it also includes a cleaning mechanism connected to the solid-liquid separation mechanism, so that as soon as the food waste enters the separation tank, the salt and grease on the food waste are washed off, improving the grease collection rate.

[0004] When the above-mentioned kitchen waste treatment equipment is in use, the oil-water mixture enters the separation box through the solid-liquid separation mechanism, and the grease is directly collected by the turntable and the oil scraper. However, for general kitchen waste, the proportion of water in the oil-water mixture is usually much greater than the proportion of oil, which makes the oil scraper's grease collection efficiency extremely low.

Therefore, the above terms should not be construed as a limitation of this utility model.

[0047] Please refer to Figures 1-2 , Figures 9-13 As shown, this application provides a solid-liquid-oil separation device for kitchen waste, including a housing 1. The housing 1 is provided with a solid-liquid separation mechanism 9 and a separation tank located below the solid-liquid separation mechanism 9. The solid-liquid separation mechanism 9 is used to separate the solids and liquids in the kitchen waste. The liquid enters the separation tank. The separation tank is provided with a baffle assembly, which includes a first baffle 24. The first baffle 24 divides the separation tank into a first separation chamber 6 and a second separation chamber. The first separation chamber 6 is used to receive the liquid separated by the solid-liquid separation mechanism 9. The upper part of the first baffle 24 is provided with a first notch 26 for connecting the first separation chamber 6 and the second separation chamber. The liquid in the first separation chamber 6 overflows into the second separation chamber through the first notch 26. A heating mechanism is provided on the outside of the first separation chamber 6 and / or the second separation chamber for heating the liquid in the first separation chamber 6 and / or the second separation chamber. Because the separation tank is equipped with a first baffle plate 24, the separation tank is divided into a first separation chamber 6 and a second separation chamber. The first separation chamber 6 is used to receive the oil-water mixture separated by the solid-liquid separation mechanism 9. In the oil-water mixture, the oil floats on the upper layer of the water. The oil layer in the first separation chamber 6 overflows into the second separation chamber through the first notch 26 to achieve oil enrichment. After enrichment, the grease is collected to improve the oil collection rate. In addition, the first separation chamber 6 and / or the second separation chamber are equipped with a heating mechanism on the outside. The heating mechanism heats the liquid in it, which can effectively prevent the grease from solidifying, further facilitate the separation of oil and water, and improve the grease collection rate.

[0048] like Figures 9-13As shown, the baffle assembly further includes a second baffle 25, which divides the second separation chamber into a first chamber 7 and a second chamber 8. The first chamber 7 is located between the first separation chamber 6 and the second chamber 8. The lower part of the second baffle 25 is provided with a second notch 27 for connecting the first chamber 7 and the second chamber 8. The first notch 26 and the second notch 27 are provided so that the first chamber 7 is connected to the first separation chamber 6 and the second chamber 8 respectively, so as to achieve the purpose of stepwise separation of oil and water. Preferably, the first notch 26 is located on the upper part of the first baffle 24. Since the density of oil in the oil-water mixture is less than that of water, the oil floats on the upper layer of the water. By placing the first notch 26 on the upper part of the first baffle 24, the upper oil layer can enter the first chamber 7, while the lower water layer can enter the first chamber 7 very little or almost not at all, so as to achieve the enrichment of oily substances in the first chamber 7. The second notch 27 is located at the lower part of the second baffle 25, and the size of the second notch 27 is much smaller than the size of the first notch 26. The second notch 27 is designed so that water in the lower part of the first compartment 7 can enter the second compartment 8 through the second notch 27 and be discharged from the second compartment 8. Understandably, the second notch 27 is equipped with a plug to prevent the oil layer from being discharged into the second compartment 8 as soon as it enters the first compartment 7.

[0049] The heating mechanism is located outside the first separation chamber 6 and / or the second separation chamber. Specifically, the heating mechanism can be a heating wire, or it can be a pipe laid at the bottom of the first separation chamber 6 and / or the second separation chamber. The pipe is connected to a circulation pump, which introduces hot water into the pipe. The hot water circulates along the pipe under the action of the circulation pump (similar to the principle of underfloor heating). The heating mechanism can also be an oil bath heating tank, in which the separation chamber is placed to heat the oil-water mixture in the separation chamber. In addition, the heating mechanism can also be a graphene heating layer installed outside the separation chamber.

[0050] In one embodiment of this disclosure, the housing 1 is provided with a feeding port 4, and a solid-liquid separation mechanism 9 is disposed between the feeding port 4 and the separation tank. The solid-liquid separation mechanism 9 is provided with a first discharge port 12 for the liquid material to flow out of the solid-liquid separation mechanism 9. The opening of the first separation chamber 6 corresponds to the first discharge port 12. A second discharge port 5 is provided on the side wall of the housing 1. Kitchen waste enters the solid-liquid separation mechanism 9 from the feeding port 4. After being separated by the solid-liquid separation mechanism 9, the solid material is discharged from the second discharge port 5, and the liquid material enters the first separation chamber 6.

[0051] It should be noted that the first chamber 7 is equipped with an oil collection mechanism 15, which includes an oil scraping assembly and an oil collection trough 32. The oil scraping assembly is used to collect the grease in the first chamber 7 into the oil collection trough 32. Specifically, the oil scraping assembly includes a rotating shaft 33, two turntables 31 mounted on the rotating shaft 33, and two scrapers 30. The scrapers 30 correspond one-to-one with the turntables 31. The rotating shaft 33 is connected to a first driving member 13, which is a motor. The first driving member 13 is used to drive the rotating shaft 33 to rotate, and the turntables 31 rotate together with the rotating shaft 33. The scrapers 30 include two first blades 34. The turntables 31 are located between the two first blades 34, and the inner side of the first blades 34 is in contact with the turntables 31. The scrapers 30 are used to scrape the grease off the turntables 31. Grease is quite viscous and has strong adsorption properties. The grease in the first chamber 7 will adhere to the turntable 31. Since the inner side of the first blade 34 is in contact with the turntable 31, when the turntable 31 rotates, the two first blades 34 scrape off the grease located on the turntable 31 between them. Because a large amount of grease is concentrated in the first chamber 7, placing the oil collection mechanism 15 in the first chamber 7 can achieve efficient oil collection. It should also be noted that since there is a certain distance between the oil collection mechanism 15 and the bottom of the first chamber 7, when the level of the oily liquid in the first chamber 7 is too low to touch the oil collection mechanism 15, water needs to be added to the first chamber 7 to raise the level of the oily liquid so that the oil collection mechanism 15 can collect the grease.

[0052] like Figure 11 , Figure 12 and Figure 14 As shown, the scraper 30 further includes a receiving plate 38 and two support frames 40 disposed on the receiving plate 38. Two first blades 34 are respectively disposed on the two support frames 40. The receiving plate 38 has an opening slot, and the turntable 31 is at least partially located in the opening slot. The two support frames 40 are respectively located on both sides of the opening slot. The first side of the support frame 40 is located closer to the turntable 31, and the second side is located farther away from the turntable 31. The height of the support frame 40 gradually decreases from the first side to the second side. Thus, the first blades 34 disposed on the support frame 40 are in an inclined state, and the inclination trend of the first blades 34 is consistent with that of the support frame 40. The inclined arrangement of the first blades 34 allows grease to slide down the slope of the first blades 34 to the outside, preventing grease from accumulating near the turntable 31. Preferably, the receiving plate 38 is provided with two wing plates 39, the length of which is greater than the length of the first blades 34. Grease slides down the slope of the first blades 34 to the outside and eventually enters the oil collection groove 32 along the wing plates 39. The wing plate 39 serves to guide the flow of grease and also effectively prevents grease from falling from the outside of the first blade 34 into the first chamber 7.

[0053] Preferably, a float is installed in the first chamber 7 to indicate the liquid level. When the liquid level in the first chamber 7 is low, the float is also low. If the liquid level is so low that the oil collecting mechanism 15 cannot contact the oil layer or only partially contacts the oil layer, the oil collection rate is low, and water needs to be added to the first chamber 7 to raise the oil layer until the turntable 31 can be mostly immersed in the oil layer. In addition, the float can also serve as a liquid level warning to prevent liquid overflow due to a high liquid level in the separation tank 1. When the liquid level of the oil-water mixture in the first chamber 7 is so low that the turntable 31 cannot contact the oil layer, water can be added to the first chamber 7 manually, or a water inlet mechanism can be added and the float connected to the controller. Once the liquid level is lower than a certain value, the controller controls the water inlet mechanism to send water into the first chamber 7.

[0054] Please refer to the following: Figures 3-6 As shown, further, one side of the oil collecting trough 32 is disposed on the second baffle plate 25. The oil collecting trough 32 includes a first guide plate 35, a second guide plate 36, and a guide channel 37. The second guide plate 36 is disposed between the first guide plate 35 and the guide channel 37. Specifically, the guide channel 37 is an arc-shaped channel. The side of the guide channel 37 away from the second guide plate 36 is disposed on the second baffle plate 25. The first guide plate 35 and the second guide plate 36 are inclined. One end of the receiving plate 38 is inclined on the first guide plate 35, and the height of the receiving plate 38 gradually decreases from the end closer to the turntable 31, so as to guide the grease into the guide channel 37. The second guide plate 36 is used to guide the grease on the scraper 30 into the guide channel 37. A first oil outlet 11 is provided on the side wall of the first chamber 7. One end of the guide channel 37 is connected to the first oil outlet 11. An oil receiving tank 10 is provided on the outside of the first chamber 7, located below the first oil outlet 11. The oil scraped off the turntable 31 by the scraper 30 finally flows into the oil receiving tank 10 through the guide channel 37. Preferably, the oil receiving tank 10 is provided with a handle to facilitate the user to lift the oil receiving tank 10.

[0055] like Figure 9 and Figure 13 As shown, specifically, the bottom of the first separation chamber 6 is provided with a first plate 28 and a second plate 29. The first plate 28 is inclined, and the second plate 29 is parallel to the horizontal plane. The first plate 28 is at least partially located directly below the first discharge port 12. The liquid flowing into the first chamber 7 from the first discharge port 12 of the solid-liquid separation mechanism 9 will inevitably contain some small solid particles. The inclined first plate 28 facilitates the settling of small solid particles.

[0056] A first vent is located on the lower side wall of the first separation chamber 6. The height of the first vent is lower than the height of the first notch 26. More specifically, the first vent is close to the bottom wall of the first separation chamber 6. The first vent is connected to a drain pipe 17, through which water in the first separation chamber 6 is discharged. A first outlet is located on the side wall of the second chamber 8. The first outlet is connected to a first drain pipe 18. The drain pipe 17 and the first drain pipe 18 are connected, and water in the drain pipe 17 flows out through the first drain pipe 18. The diameter of the first drain pipe 18 is larger than the diameter of the drain pipe 17. The water in the drain pipe 17 eventually merges with the water in the first drain pipe 18. This arrangement simplifies the drainage pipe structure, requiring only the connection of the first drain pipe 18 to an external pipeline.

[0057] Because the first separation chamber 6 contains some small solid particles, these particles either settle at the bottom of the first separation chamber 6 or float in the oil-water mixture, resulting in a relatively high amount of impurities in the liquid within the first separation chamber 6. Therefore, it is necessary to periodically empty the first separation chamber 6 to remove the solid sediment. To facilitate the smooth removal of sediment, an emptying pump 19 is connected to the emptying pipe 17.

[0058] Small solid particles floating in the oil-water mixture in the first separation chamber 6 will enter the first chamber 7. Preferably, a second vent is provided at the lower part of the first baffle plate 24, and a one-way valve is provided at the second vent. When the first chamber 7 needs to be emptied, the one-way valve is opened, allowing the sediment in the first chamber 7 to enter the first separation chamber 6 through the second vent, and then discharged through the vent pipe 17 under the action of the vent pump 19. Specifically, the first baffle plate 24 is inclined, and the one-way valve is a metal plate hinged to the first baffle plate 24. The metal plate is located on one side of the first separation chamber 6. When the vent pump 19 is working, a negative pressure is formed in the first separation chamber 6, and the metal plate is shifted to the side of the first separation chamber 6, opening the second vent and allowing the sediment in the first chamber 7 to enter the first separation chamber 6.

[0059] In order to collect as much grease as possible from the first separation chamber 6, the first separation chamber 6 is equipped with a cleaning pipe 16. The cleaning pipe 16 is used to connect to a water source to clean the first separation chamber 6 and prevent grease from adhering to the inner wall of the first separation chamber 6.

[0060] Please refer to Figures 6-8As shown in one embodiment of this disclosure, the solid-liquid separation mechanism 9 includes a separation cylinder, a second discharge port 5 located at one end of the separation cylinder, a rotating rod 21 and separation blades 20 disposed within the separation cylinder, the separation blades 20 being spirally mounted on the rotating rod 21, the rotating rod 21 being connected to a second driving member 14, which is a motor, used to drive the rotating rod 21 to rotate. When the rotating rod 21 rotates, it drives the separation blades 20 to rotate as well. A feed inlet is provided on the upper side of the separation cylinder, and a perforated portion 22 is provided on the lower side of the separation cylinder. Specifically, the perforated portion 22 is a screen, and a first discharge port 12 is located at the position of the perforated portion 22. During the rotation of the blades, the solid kitchen waste in the separation cylinder is driven to one side for collection, thereby causing the solid kitchen waste to exit from the second discharge port 5, while the liquid kitchen waste passes through the perforated portion 22 and enters the first separation chamber 6 through the first discharge port 12.

[0061] Specifically, the separating cylinder is inclined above the separating tank, and its height above the first separating chamber 6 is lower than its height above the second separating chamber. The second discharge port 5 is located on the side away from the first separating chamber 6. The length of the hollowed-out portion 22 is greater than the length of the inlet. An arc-shaped plate 23 adapted to the shape of the separating cylinder is provided on the outer side of the hollowed-out portion 22. The first discharge port 12 is located on the arc-shaped plate 23, and the length of the hollowed-out portion 22 is greater than the length of the first discharge port 12. This arrangement allows the hollowed-out portion 22 to continue filtering the moving kitchen waste as it moves towards the second discharge port due to the rotation of the separating blades 20, resulting in more thorough solid-liquid separation in the kitchen waste. The inclined positioning of the separating cylinder above the separating tank allows the liquid filtered by the hollowed-out portion 22 to collect at the position of the first discharge port 12 under the action of gravity and flow towards the first separating chamber 6.

[0062] The container 1 is equipped with a countertop, and a guide structure 3 is provided on the countertop to guide kitchen waste to the feeding port 4. A cover plate 2 is provided at the opening of the guide structure 3.

[0063] This application also provides another solid-liquid-oil separation device for kitchen waste, including a housing 1. The housing 1 contains a solid-liquid separation mechanism 9 and a separation tank. The separation tank is located below the solid-liquid separation mechanism 9 and is used to collect the liquid separated by the mechanism. The separation tank is equipped with an emptying mechanism, which includes a three-way valve and an emptying pump 19 connected to the three-way valve. The three-way valve includes a first opening, a second opening, and a third opening. The line connecting the center of the first opening and the center of the second opening is perpendicular to the horizontal plane. A gap is provided between the first opening and the bottom of the separation tank. The third opening passes through the side wall of the separation tank and connects to the emptying pump 19. When the separation tank needs to be emptied, the emptying pump 19 is activated to discharge the sediment at the bottom of the separation tank. It is understood that the second opening is located above the first opening, with the second opening facing upwards and the first opening facing downwards. The liquid level in the separation tank should not be higher than the second opening to prevent liquid from entering the three-way valve through the second opening. In this embodiment, some common fixing components can be used to fix the three-way valve in the separation tank, maintaining a certain gap between it and the separation tank to allow sediment to enter.
