Description

Technical Field

[0001] This application belongs to the field of food waste separation technology, specifically an oil-water separation device for food waste. Background Technology

[0002] Wastewater discharged from hotels, restaurants, and other catering industries contains not only solid residues but also oil-water mixtures. Direct discharge after removing the residue would cause serious environmental pollution. To prevent this, catering companies typically separate the oil and water in their kitchen waste before further treatment.

[0003] For example, patent number CN213294786U discloses a kitchen waste oil-water separation device, including a body. The top of the body is provided with a residue inlet, and below the residue inlet is a dehydration chamber. The dehydration chamber is provided with a dehydration device, which includes a dehydration bucket, a rotating seat, and a motor. The interior of the body is also provided with a sedimentation chamber and a separation chamber. The sedimentation chamber is provided with a sedimentation inclined plate, and the bottom of the sedimentation chamber is provided with a slag collection hopper, the bottom of which has a slag outlet. The separation chamber is provided with a floating oil collector, and the side wall of the separation chamber is provided with a wastewater outlet and a waste oil outlet. The floating oil collector is connected to the waste oil outlet through a hose. This utility model has a simple structure, low cost, and is easy to promote, making it more suitable for use in smaller catering establishments.

[0004] In the process of developing this application, the following problems were found with this technology: When the device is in use, food waste enters the dehydration tank and is separated from oil and water after high-speed rotation for subsequent oil-water separation. However, due to the high-speed rotation, food residue is easily blocked in the filter holes on the dehydration tank, which reduces the dehydration efficiency. Frequent manual removal and cleaning of the filter holes will also cause a certain burden to the user. Therefore, in order to solve this problem and optimize this design, it is necessary to propose an oil-water separation device for food waste. Utility Model Content

[0005] The purpose of this application is to provide an oil-water separation device for kitchen waste in order to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: An oil-water separation device for kitchen waste includes a separation cylinder. A filter box is fixedly installed on the top left side of the separation cylinder. A filter cylinder with its left end tilted downwards is rotatably installed inside the filter box. The lower left end of the filter cylinder extends out of the outer wall of the filter box. A fixing ring is fixedly installed on the right side of the inner cavity of the filter box. The left side of the fixing ring is rotatably installed with the filter cylinder via a bearing. A rotating shaft seal is provided at the penetration position between the filter cylinder and the left side of the filter box. A feed pipe is fixedly installed on the right side of the outer wall of the filter box. The lower end of the feed pipe penetrates into the filter box and is inserted into the upper right side of the filter cylinder. Inside the port, the outer wall of the filter cartridge has circumferentially distributed filter holes. A toothed ring is fixedly installed on the right side of the outer periphery of the filter cartridge. A side plate is fixedly installed on the outer wall of the filter cartridge. A connecting rod is slidably installed on the inner side of the side plate. Multiple unblocking blocks opposite to the filter holes are fixedly installed on the connecting rod. Rotary wheels are rotatably installed on the outer sides of both ends of the connecting rod. An observation window made of transparent tempered glass is provided on the upper left side of the separation cartridge. A second sealing cap is installed on the top of the separation cartridge by screws. An oil pump and a water pump are fixedly installed on the lower left side of the separation cartridge and on the top of the second sealing cap, respectively.

[0007] In a preferred embodiment, the filter box and the inner cavity of the separation cylinder are connected to each other, and a No. 1 sealing cover is installed on the top of the filter box by screws.

[0008] In a preferred embodiment, a fixing plate is fixedly installed on the top of the fixing ring, and a motor is fixedly installed on the middle left side of the fixing plate. The output shaft of the motor is fixedly connected to a gear, which meshes with the gear ring.

[0009] In a preferred embodiment, the inner side of the side plate is provided with a sliding groove adapted to the end of the connecting rod, and a guide rod inserted into the end of the connecting rod is fixedly installed in the sliding groove. A spring is provided at the end of the connecting rod below the outer wall of the guide rod.

[0010] In a preferred embodiment, a top rod is fixedly installed on the upper left side of the fixing plate, and an arc plate is fixedly installed on the inner side of the top rod at the position of the rotating wheel.

[0011] In a preferred embodiment, a slag receiving tube is engaged and installed on the lower left side of the filter box, with the upper opening of the slag receiving tube facing the lower left end of the filter tube.

[0012] In a preferred embodiment, the water pump is fixedly connected to a rigid water pumping pipe at its pumping end, and the lower end of the water pumping pipe is located at the bottom of the inner cavity of the separator. The oil pump is fixedly connected to an oil pumping pipe at its pumping end, and the oil pumping pipe is connected to the bottom of the inner cavity of the separator.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0014] 1. In this application, through the above design, when using this device, the kitchen waste is first poured in through the feed pipe. At this time, the kitchen waste will flow into the upper right opening of the inclined filter cylinder through the lower opening of the feed pipe. Then, the motor is started to drive the gear to rotate, and the gear drives the filter cylinder to rotate through the meshing gear ring. This causes the kitchen waste in the filter cylinder to slowly move to the left during rotation and finally fall into the slag collection cylinder for collection. During this process, the oil and water in the kitchen waste are discharged into the bottom of the filter box through the filter holes and finally flow into the separation cylinder to collect. When the filter cylinder rotates to filter the kitchen waste, because the unblocking block is set on the outside of the filter hole, when the filter cylinder drives the connecting rod on the inner side of the side plate and the rotating wheel on the connecting rod to rotate together, once the rotating wheel passes the arc plate, it will squeeze the arc plate and move towards the filter cylinder. At this time, the rotating wheel drives the filter cylinder to rotate. The unblocking block on the connecting rod is inserted into the filter hole to unclog it and prevent blockage. Since this process occurs at the top of the filter cylinder, the residue that has been unclogged in the filter hole can continue to fall into the filter cylinder, thereby improving the unblocking effect and ensuring the normal operation of the separation of kitchen waste and oil and water. Of course, when the separated oil and water enter the separation cylinder, the user can observe the oil and water level in the separation cylinder through the observation window. When the oil and water in the separation cylinder accumulate to a certain level, let it stand for a period of time. At this time, the light oil will float on the surface of the water and accumulate. At this time, the external pipe is connected to the drain end of the water pump, and the water pump is started to first pump out the water below the oil layer in the separation cylinder through the water pump pipe. Then, combined with the observation through the observation window, the oil pump is started to pump out the oil layer accumulated in the separation cylinder, thereby achieving effective separation of oil and water.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] Reference Figure 1 , 2 3. An oil-water separator for kitchen waste includes a separation cylinder 1. A filter box 2 is fixedly installed on the top left side of the separation cylinder 1. The filter box 2 is connected to the inner cavity of the separation cylinder 1. A sealing cover 3 is screwed onto the top of the filter box 2. A filter cylinder 4 with its left end tilted downwards is rotatably installed inside the filter box 2. The lower left end of the filter cylinder 4 extends out of the outer wall of the filter box 2. A fixing ring 6 is fixedly installed on the right side of the inner cavity of the filter box 2. The left side of the fixing ring 6 is rotatably installed with the filter cylinder 4 via a bearing. A rotating shaft seal is provided at the penetration position between the filter cylinder 4 and the left side of the filter box 2. A slag receiving cylinder 18 is fitted and installed on the lower left side of the filter cylinder 4. The upper opening of the slag receiving cylinder 18 is directly opposite the lower left end of the filter cylinder 4. A feed pipe 5 is fixedly installed on the right side of the outer wall of the filter box 2. The lower end of the feed pipe 5 passes through the filter box 2 and is inserted into the upper right end of the filter cylinder 4. The outer wall of the filter cylinder 4 has filter holes 7 distributed in a circumferential manner. A toothed ring 8 is fixedly installed on the right side of the outer periphery of the filter cylinder 4. A fixing plate 9 is fixedly installed on the top of the fixing ring 6. A motor 10 is fixedly installed on the middle left side of the fixing plate 9. A gear 11 is fixedly connected to the output shaft of the motor 10. The gear 11 meshes with the toothed ring 8.

[0021] With the above design, when using this device, the kitchen waste is first poured in through the feed pipe 5. At this time, the kitchen waste will be discharged into the upper right opening of the inclined filter cylinder 4 through the lower opening of the feed pipe 5. Then, the motor 10 is started to drive the gear 11 to rotate. The gear 11 drives the filter cylinder 4 to rotate through the meshing gear ring 8. As a result, the kitchen waste in the filter cylinder 4 slowly moves to the left during rotation and finally falls into the slag receiving cylinder 18 for collection. During this process, the oil and water in the kitchen waste are discharged into the bottom of the filter box 2 through the filter holes 7 and finally flow into the separation cylinder 1 to collect.

[0022] Reference Figure 1 , 23. A side plate 12 is fixedly installed on the outer wall of the filter cartridge 4. A connecting rod 13 is slidably installed on the inner side of the side plate 12. A groove adapted to the end of the connecting rod 13 is opened on the inner side of the side plate 12, and a guide rod inserted into the end of the connecting rod 13 is fixedly installed in the groove. A spring is set on the lower outer wall of the guide rod at the end of the connecting rod 13. Multiple unblocking blocks 14 are fixedly installed on the connecting rod 13 and are arranged opposite to the filter holes 7. Rotary wheels 15 are rotatably installed on the outer sides of both ends of the connecting rod 13. A top rod 16 is fixedly installed on the upper left side of the fixed plate 9. The inner side of the top rod 16 is located on the rotating wheel. An arc plate 17 is fixedly installed at position 15. An observation window 19 made of transparent tempered glass is provided on the upper left side of the separation cylinder 1. A second sealing cover 20 is installed on the top of the separation cylinder 1 by screws. An oil pump 21 and a water pump 22 are fixedly installed on the lower left side of the separation cylinder 1 and the top of the second sealing cover 20, respectively. A rigid water pump pipe is fixedly connected to the water pump 22, and the lower end of the water pump pipe is located at the bottom of the inner cavity of the separation cylinder 1. An oil pump pipe is fixedly connected to the oil pump 21, and the oil pump pipe is connected to the bottom of the inner cavity of the separation cylinder 1.

[0023] Through the above design, when the filter cartridge 4 rotates to filter kitchen waste, the unblocking block 14 is installed on the outside of the filter hole 7. When the filter cartridge 4 rotates together with the connecting rod 13 on the inner side of the side plate 12 and the rotating wheel 15 on the connecting rod 13, the rotating wheel 15, once it passes the arc plate 17, will squeeze the arc plate 17 and move towards the filter cartridge 4. At this time, the rotating wheel 15 drives the unblocking block 14 on the connecting rod 13 to insert into the filter hole 7 to unblock the filter hole 7 and prevent blockage. Because this process occurs at the top of the filter cartridge 4, the residue that has been unblocked in the filter hole 7 can continue to fall into the filter cartridge 4, thereby improving the unblocking effect. To ensure the proper functioning of the separation of kitchen waste and oil and water, the user can observe the oil and water level in the separation cylinder 1 through the observation window 19 after the separated oil and water have entered the separation cylinder 1. When the oil and water in the separation cylinder 1 accumulate to a certain level, it is left to stand for a period of time. At this time, the light oil floats on the surface of the water and accumulates. At this time, the external pipe is connected to the drain end of the water pump 22, and the water pump 22 is started to pump out the water below the oil layer in the separation cylinder 1 through the water pump pipe. Then, in conjunction with the observation through the observation window 19, the oil pump 21 is started to pump out the oil layer that has accumulated in the separation cylinder 1, thereby achieving effective separation of oil and water.

[0024] The implementation principle of this application embodiment is as follows:

[0025] When using this device, firstly, the kitchen waste is poured in through the feed pipe 5. At this time, the kitchen waste will flow into the upper right opening of the inclined filter cylinder 4 through the lower opening of the feed pipe 5. Then, the motor 10 is started to drive the gear 11 to rotate. The gear 11 drives the filter cylinder 4 to rotate through the meshing gear ring 8. This causes the kitchen waste in the filter cylinder 4 to slowly move to the left during rotation and eventually fall into the slag collection cylinder 18 for collection. During this process, the oil and water in the kitchen waste are discharged into the bottom of the filter box 2 through the filter holes 7 and eventually flow into the separation cylinder 1 to collect. When the filter cylinder 4 rotates to filter the kitchen waste, because the unblocking block 14 is set on the outside of the filter holes 7, when the filter cylinder 4 drives the connecting rod 13 on the inner side of the side plate 12 and the rotating wheel 15 on the connecting rod 13 to rotate together, once the rotating wheel 15 passes the arc plate 17, it will squeeze the arc plate 17 and move towards the filter cylinder 4. At this time, the rotating wheel 15 drives the filter cylinder 4 to rotate. The unblocking block 14 on the connecting rod 13 is inserted into the filter hole 7 to unblock the filter hole 7 and prevent blockage. Since this process occurs above the filter cylinder 4, the residue that has been unblocked in the filter hole 7 can continue to fall into the filter cylinder 4, thereby improving the unblocking effect and ensuring that the separation of kitchen waste and oil and water is carried out normally. Of course, when the separated oil and water come into the separation cylinder 1, the user can observe the oil and water level in the separation cylinder 1 through the observation window 19. When the oil and water in the separation cylinder 1 accumulate to a certain position, let it stand for a period of time. At this time, the light oil floats on the surface of the water and accumulates. At this time, the external pipe is connected to the drain end of the water pump 22, and the water pump 22 is started to first pump out the water below the oil layer in the separation cylinder 1 through the water pump pipe. Then, combined with the observation through the observation window 19, the oil pump 21 is started to pump out the oil layer accumulated in the separation cylinder 1, thereby achieving effective separation of oil and water.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
