Description

Technical Field

[0001] This utility model belongs to the field of anhydrous oil refining, specifically an anhydrous oil refining device. Background Technology

[0002] The process is as follows: crude oil → filtration → degumming → alkali refining → water washing → decolorization → deodorization → refined oil. This process requires high temperature and vacuum conditions, resulting in high equipment investment, stringent process requirements, low oil yield, and wastewater generation during refining. Refining at temperatures above 200℃ significantly damages the active substances in the oil and produces harmful trans fatty acids, causing the oil to lose its natural characteristics and greatly reducing its health benefits and application value. Furthermore, the water washing process uses a large amount of water, which becomes wastewater after washing, wasting water resources. The wastewater also requires prior wastewater treatment before discharge, increasing production costs. Therefore, there is room for improvement.

[0003] An existing anhydrous oil refining unit has evolved to achieve anhydrous refining. Through technological innovation, this unit has achieved the dual goals of environmental protection and economic efficiency. Its modular design, intelligent control, and resource-efficient utilization characteristics are driving the oil processing industry towards a green and sustainable transformation. With further technological advancements, this unit will be more widely used globally, providing high-quality raw materials for the food, chemical, and other industries.

[0004] In the existing oil refining process, a filter layer is needed to effectively filter the oil, thereby forming a filter cake of a certain thickness on top of the filter layer. However, waiting for the filtration process to proceed naturally takes too long. Since the filter cake covers the surface of the filter layer, it will significantly affect the filtration speed of subsequent oils, resulting in a significant reduction in work efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The present utility model provides an anhydrous oil refining device, including a separation tank; a cover plate is fixedly connected to the top of the separation tank, and an oil storage tank is connected to the bottom of the separation tank. An inlet is provided at the top of the separation tank, and an oil outlet is provided at the bottom of the oil storage tank. A motor is provided on one side of the inlet, and the motor is fixedly connected to the cover plate. A straight shaft is fixedly connected to the bottom of the motor, and the straight shaft is rotatably connected to the cover plate. Multiple stirring rods are fixedly connected to the outside of the straight shaft, and a scraper is fixedly connected to the bottom of the straight shaft. A filter layer is provided at the bottom of the scraper, and the filter layer is connected to the separation tank... The separator features a sliding connection. During operation, grease is poured into the separator from the inlet, filtered through the filter layer, and accumulates in the oil storage tank. The motor starts, driving the linear shaft and stirring rod to rotate, agitating the grease and reducing its solidification. This slows down the filtration process, causing filter cake to accumulate on the upper layer of the filter layer after a period of time. The scraper removes the filter cake, removing it from the top of the filter layer and reducing its coverage, thus accelerating the grease filtration speed. By using a motor to drive the linear shaft and stirring rod to agitate the grease in the separator, the solidification of the upper layer of grease during filtration is reduced, preventing slow flow and thus affecting filtration efficiency.

[0007] Preferably, the filter layer has a slot on one side, which is formed on the surface of the separation tank. A locking block is engaged in the middle of the slot, and the locking block is fixedly connected to the filter layer and slidably connected to the separation tank. During operation, the filter layer is fixed to the separation tank by the engagement of the slot and the locking block. The filter layer can be removed from the separation tank to clean the filter cake that has precipitated on it, and it is also convenient to clean the filter layer for future use. By setting the slot and the locking block, the filter layer can be installed and removed, which facilitates the replacement and cleaning of the filter layer and reduces the possibility of clogging, which could affect the filtration efficiency.

[0008] Preferably, an air compressor is provided on one side of the motor. The air compressor is fixedly connected to the cover plate. One end of the air compressor is connected to a pipe, which is connected to the separation tank. The pipe is fixedly connected to the cover plate. During operation, after the grease filtration is completed, the air compressor is started, and compressed air enters the separation tank through the pipe. It acts on the filter cake to squeeze out the residual grease in the filter cake, reducing material loss and saving costs.

[0009] Preferably, a scraper is fixedly connected to the top of the slot, and the scraper is in corresponding contact with the filter layer. During operation, after the oil filtration is completed, when the entire separation tank is cleaned, the filter layer is removed from the separation tank by pulling the locking block outward to make the filter layer slide out of the slot. The scraper will scrape off the filter cake accumulated on the filter layer, and the filter cake residue will fall out from the oil outlet. Then, clean water or cleaning fluid is introduced into the separation tank to rinse and clean the separation tank and oil storage tank. After drying and draining, the filter layer can be reinstalled.

[0010] Preferably, the outer side of the separator is provided with a heat insulation layer, which is fixedly connected to the separator. During operation, the heat insulation layer heats the separator, reducing the phenomenon that the oil in the separator will solidify due to low temperature, which would prevent the straight shaft and stirring rod from stirring properly and thus enhance its fluidity.

[0011] Preferably, sealing rings are fixedly connected to both sides of the card block. The sealing rings engage with the card slot. During operation, the sealing rings fill the gap between the card slot and the card block to ensure the sealing of the separation tank, reduce grease leakage, and prevent material damage and increased costs.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The anhydrous oil refining device of this utility model uses a motor to drive a straight shaft and a stirring rod to stir the oil in the separation tank, thereby reducing the solidification of the upper layer of oil during filtration, which leads to slow flow and thus affects the filtration efficiency.

[0014] 2. The anhydrous oil refining device of this utility model enables the installation and disassembly of the filter layer by setting a slot and a locking block, which facilitates the replacement and cleaning of the filter layer and reduces the possibility of clogging of the filter layer, thus reducing the impact on filtration efficiency.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 3 As shown in the embodiment of this utility model, an anhydrous oil refining device includes a separation tank 1; a cover plate 11 is fixedly connected to the top of the separation tank 1, and an oil storage tank 12 is connected to the bottom of the separation tank 1. An inlet 13 is provided at the top of the separation tank 1, and an oil outlet 14 is provided at the bottom of the oil storage tank 12. A motor 15 is provided on one side of the inlet 13, and the motor 15 is fixedly connected to the cover plate 11. A straight shaft 16 is fixedly connected to the bottom of the motor 15, and the straight shaft 16 is rotatably connected to the cover plate 11. Multiple stirring rods 17 are fixedly connected to the outside of the straight shaft 16, and a scraper 18 is fixedly connected to the bottom of the straight shaft 16. A filter layer 19 is provided at the bottom of the scraper 18, and the filter layer 19 is connected to the separation tank 14. Tank 1 is slidably connected. During operation, grease is poured into the separator tank 1 through the feed inlet 13, filtered through the filter layer 19, and accumulates at the oil storage tank 12. The motor 15 starts, driving the straight shaft 16 and the stirring rod 17 to rotate, stirring the grease and reducing the phenomenon of grease solidification. This causes the filter layer 19 to filter the grease slowly. After a period of time, a filter cake slowly accumulates on the upper layer of the filter layer 19. The scraper 18 scrapes off the filter cake, removing it from the top of the filter layer 19, reducing the amount of grease covering the filter layer 19, and accelerating the grease filtration speed. By setting the motor 15 to drive the straight shaft 16 and the stirring rod 17 to rotate, the grease in the separator tank 1 is stirred, reducing the solidification of the upper layer of grease during filtration, which would lead to slow flow and thus affect the filtration efficiency.

[0024] like Figures 1 to 5 As shown, a slot 2 is provided on one side of the filter layer 19. The slot 2 is formed on the surface of the separation tank 1. A locking block 21 is engaged in the middle of the slot 2. The locking block 21 is fixedly connected to the filter layer 19 and slidably connected to the separation tank 1. During operation, the filter layer 19 is fixed to the separation tank 1 by the engagement of the slot 2 and the locking block 21. The filter layer 19 can be removed from the separation tank 1 to clean the filter cake precipitated on the filter layer 19 and facilitate cleaning of the filter layer 19 for future use. By setting the slot 2 and the locking block 21 to engage, the filter layer 19 can be installed and removed, making it convenient to replace and clean the filter layer 19 and reducing the possibility of clogging of the filter layer 19, which could affect the filtration efficiency.

[0025] like Figures 1 to 2As shown, an air compressor 3 is provided on one side of the motor 15. The air compressor 3 is fixedly connected to the cover plate 11. One end of the air compressor 3 is connected to a pipe 31, which is connected to the separation tank 1. The pipe 31 is fixedly connected to the cover plate 11. During operation, after the grease filtration is completed, the air compressor 3 is started. Compressed air enters the separation tank 1 through the pipe 31 and acts on the filter cake to squeeze out the residual grease in the filter cake, reducing material loss and saving costs.

[0026] like Figures 1 to 4 As shown, a scraper 4 is fixedly connected to the top of the slot 2. The scraper 4 is in contact with the filter layer 19. During operation, after the grease filtration is completed, when the entire separation tank 1 is cleaned, the filter layer 19 is removed from the separation tank 1. The card block 21 is pulled outward to make the filter layer 19 slide out of the slot 2. The scraper 4 will scrape off the filter cake accumulated on the filter layer 19. The filter cake residue falls out from the oil outlet 14. Then, clean water or cleaning fluid is introduced into the separation tank 1 to rinse and clean the separation tank 1 and the oil storage tank 12. After drying and draining, the filter layer 19 can be reinstalled.

[0027] like Figures 1 to 2 As shown, the outer side of the separation tank 1 is provided with a heat insulation layer 5, which is fixedly connected to the separation tank 1. During operation, the heat insulation layer 5 keeps the separation tank 1 warm, slows down the cooling of the oil in the separation tank 1, and avoids solidification due to severe cooling, which would prevent the straight shaft 16 and stirring rod 17 from stirring properly and thus fail to enhance its fluidity.

[0028] like Figure 5 As shown, sealing rings 6 are fixedly connected to both sides of the card block 21. The sealing rings 6 are engaged with the card groove 2. During operation, the sealing rings 6 fill the gap between the card groove 2 and the card block 21 to ensure the sealing of the separation tank 1, reduce the phenomenon of grease leakage, and prevent material damage and increased costs.

[0029] Working principle: Oil is poured into the separator 1 through the feed inlet 13, filtered through the filter layer 19, and accumulates at the oil storage tank 12. The motor 15 starts, driving the linear shaft 16 and the stirring rod 17 to rotate, stirring the oil and reducing the phenomenon of oil solidification. This causes the filter layer 19 to filter the oil slowly. After a period of time, a filter cake slowly accumulates on the upper layer of the filter layer 19. The scraper 18 scrapes off the filter cake, removing it from the top of the filter layer 19, reducing the amount of oil covering the filter layer 19, and accelerating the oil filtration speed. The motor 15 drives the linear shaft 16 and the stirring rod 17. Rotation agitates the grease within the separator 1, reducing the risk of upper grease solidification during filtration, which slows flow and affects filtration efficiency. The filter layer 19 is secured to the separator 1 via a slot 2 and a locking block 21. The filter layer 19 can be removed from the separator 1 for cleaning the precipitated filter cake and for easy washing before future use. The slot 2 and locking block 21 facilitate the installation and removal of the filter layer 19, enabling convenient replacement and cleaning, and reducing grease buildup. If the filter layer 19 becomes clogged, affecting filtration efficiency, after grease filtration is complete, the air compressor 3 is started, and compressed air enters the separator 1 through the pipe 31, acting on the filter cake to squeeze out the residual grease, reducing material loss and saving costs. After grease filtration is complete, when cleaning the separator 1 as a whole, the filter layer 19 is removed from the separator 1 by pulling the locking block 21 outward, causing the filter layer 19 to slide out of the locking groove 2. The scraper 4 scrapes off the filter cake accumulated on the filter layer 19, and the filter cake residue falls from the oil outlet 14. After that, clean water or cleaning fluid is introduced into the separator 1 to rinse and clean the separator 1 and the oil storage tank 12. After drying and draining, the filter layer 19 can be reinstalled. The heat insulation layer 5 heats the separator 1 to reduce the phenomenon that the oil in the separator 1 will solidify due to low temperature, which would prevent the straight shaft 16 and the stirring rod 17 from mixing properly and thus not enhance its fluidity. The sealing ring 6 fills the gap between the slot 2 and the block 21 to ensure the sealing of the separator 1 and reduce the phenomenon of oil leakage, which could lead to material damage and increased costs.
