A purification device for vegetable oil processing

Abstract

This utility model discloses a purification device for vegetable oil processing, including a filter tank and a stabilizing assembly. The filter tank has a discharge port at its lower end. The stabilizing assembly is installed inside the filter tank, with a fine filter cartridge installed inside the stabilizing assembly. A scraper assembly is installed inside the fine filter cartridge, and a coarse filter cartridge is installed inside the scraper assembly. A rotating shaft is welded to the bottom of the coarse filter cartridge, and a bevel gear assembly is installed at the lower end of the rotating shaft. Compared with existing purification devices, this purification device for vegetable oil processing uses a circulating pump to drive the flow of heat-conducting liquid in a spiral heat-conducting tube. After being detected by a temperature sensor, the liquid is heated to the target temperature by a heater, causing the vegetable oil to be uniformly heated to 15-18℃ to reduce its kinematic viscosity. After the oil flows into the filter tank, a motor drives the rotating shaft through the bevel gear assembly to rotate the coarse and fine filter cartridges. Centrifugal force accelerates the dual filtration process. The relative movement of the scraper assembly and the rotating filter cartridge removes surface impurities, and pulleys and a ring rail stabilize the position of the fine filter cartridge.

Description

Technical Field

[0001] This utility model relates to the field of vegetable oil processing technology, specifically to a purification device for vegetable oil processing. Background Technology

[0002] Vegetable oils are compounds formed by the reaction of higher fatty acids and glycerol [1]. They are widely distributed in nature and are oils obtained from the fruits, seeds, and germs of plants, such as peanut oil, soybean oil, linseed oil, castor oil, and rapeseed oil. The main components of vegetable oils are esters formed by the reaction of straight-chain higher fatty acids and glycerol. In addition to palmitic acid, stearic acid, and oleic acid, the fatty acids also contain a variety of unsaturated acids, such as erucic acid, tung oil acid, and ricinoleic acid. Vegetable oils mainly contain vitamin E, vitamin K, minerals such as calcium, iron, phosphorus, and potassium, as well as fatty acids. The fatty acids in vegetable oils can make the skin moisturized and shiny.

[0003] Current vegetable oil processing typically requires filtration and purification. In winter or in low-temperature regions, when the temperature drops below 12°C, vegetable oils (such as edible oils) will crystallize, forming milky white or pale yellow flocculent substances similar to cotton. If the temperature drops to around 3°C, the oil gradually solidifies, turning pale yellow or milky white, but still retaining some fluidity. This significantly affects filtration efficiency and the overall efficiency of vegetable oil processing, necessitating a purification device for vegetable oil processing. Utility Model Content

[0004] The purpose of this invention is to provide a purification device for vegetable oil processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a purification device for vegetable oil processing, comprising a filter tank and a stabilizing assembly. The filter tank has a discharge port installed at its lower end. The stabilizing assembly is installed inside the filter tank at its upper part, and a fine filter cylinder is installed inside the stabilizing assembly. A scraper assembly is installed inside the fine filter cylinder, and a coarse filter cylinder is installed inside the scraper assembly. A rotating shaft is welded to the lower part of the coarse filter cylinder, and a bevel gear assembly is installed at the lower end of the rotating shaft. The fine filter cylinder and the coarse filter cylinder are welded to the rotating shaft, and the rotating shaft and the scraper assembly are rotatably connected.

[0006] Furthermore, the stabilizing component includes a ring rail and a pulley, with the pulley slidably connected to the inner side of the ring rail. The upper end of the fine filter cartridge rotates in the ring rail via the pulley, restraining the upper end of the fine filter cartridge and preventing it from shaking when rotating.

[0007] Furthermore, an isolation shell is installed around the bevel gear set, and a motor is installed at the right end of the bevel gear set. The bevel gear set is isolated from the vegetable oil in the isolation shell to prevent it from affecting the quality of the vegetable oil.

[0008] Furthermore, a valve is installed above the filter tank, and a preheating tank is installed above the valve. Vegetable oil flows into the filter tank through the valve, and the flow rate of the valve is adjustable.

[0009] Furthermore, a spiral heat-conducting pipe is installed inside the preheating tank, and a circulation pump is connected to the right side of the spiral heat-conducting pipe. The circulation pump drives the heat-conducting liquid in the spiral heat-conducting pipe to circulate. Heat-conducting plates are evenly arranged on the spiral heat-conducting pipe to increase the contact area and improve the heating effect.

[0010] Furthermore, a heater is installed above the circulating pump, and a temperature sensor is installed above the heater. After the temperature of the heat-conducting liquid is measured by the temperature sensor, it flows through the heater. The heater heats the heat-conducting liquid, and the heat-conducting liquid uniformly heats the vegetable oil to 15-18°C through the spiral heat-conducting tube.

[0011] Furthermore, a feed inlet is installed on the upper left side of the preheating tank, and an air valve is provided on one side of the feed inlet. Vegetable oil is poured into the preheating tank through the feed inlet, and the air valve balances the air pressure inside and outside the preheating tank to facilitate feeding.

[0012] Furthermore, a vibrator is installed on the left side of the preheating tank, and the vibrator is welded to the preheating tank. The high-frequency vibration emitted by the vibrator drives the entire device to vibrate, preventing vegetable oil from sticking to the preheating tank, the inner wall of the filter tank, and the spiral heat conduction pipe and other structures.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: Vegetable oil is injected into the preheating tank through the inlet, and the air valve maintains the pressure balance inside and outside the tank. A circulating pump drives the flow of heat-conducting liquid in the spiral heat-conducting pipe. After being detected by a temperature sensor, the liquid is heated to the target temperature by a heater. The heat-conducting fins enhance heat transfer efficiency, allowing the vegetable oil to be uniformly heated to 15-18℃ to reduce its kinematic viscosity. High-frequency vibration of the vibrator prevents the oil from sticking to the tank wall and pipes. The flow rate is regulated by the valve. After the oil flows into the filter tank, the motor drives the rotating shaft through a bevel gear set to rotate the coarse and fine filter cartridges. Centrifugal force accelerates the dual filtration process. The scraper assembly moves relative to the rotating filter cartridge to remove surface impurities, and the pulley and ring rail stabilize the position of the fine filter cartridge. The vibrator synchronously promotes smooth discharge from the outlet. 1. In this utility model, when the valve is opened, vegetable oil flows into the filter tank through the valve. The flow rate of the valve is adjustable. The vegetable oil flows into the coarse filter cartridge. The motor drives the rotating shaft to rotate through the bevel gear set. The rotating shaft drives the coarse filter cartridge and the fine filter cartridge to rotate, generating centrifugal force. Under the action of centrifugal force, the vegetable oil quickly passes through the coarse filter cartridge and the fine filter cartridge for double filtration and is thrown onto the inner wall of the filter tank. The scraper assembly is fixed on the filter tank and rotates relative to the rotating fine filter cartridge and the coarse filter cartridge, thereby scraping off the impurities attached to the surface of the fine filter cartridge and the coarse filter cartridge, preventing the coarse filter cartridge and the fine filter cartridge from clogging. The upper end of the fine filter cartridge rotates in the ring track through the pulley, restraining the upper end of the fine filter cartridge and preventing the fine filter cartridge from shaking when rotating. The bevel gear set is isolated from the vegetable oil in the isolation shell to prevent it from affecting the quality of the vegetable oil. The high-frequency vibration generated by the vibrator drives the overall vibration of the device, which also helps the material to be discharged from the outlet. 2. This utility model pours vegetable oil into a preheating tank through the inlet. The air valve balances the air pressure inside and outside the preheating tank, facilitating feeding. A circulation pump drives the heat-conducting liquid in the spiral heat-conducting tube to circulate. After the temperature of the heat-conducting liquid is measured by a temperature sensor, it flows through a heater. The heater heats the heat-conducting liquid, and the heat-conducting liquid uniformly heats the vegetable oil to 15-18℃ through the spiral heat-conducting tube. Heat-conducting plates are evenly arranged on the spiral heat-conducting tube to increase the contact area and improve the heating effect. After heating, the kinematic viscosity of the vegetable oil is significantly reduced, improving the filtration efficiency. The high-frequency vibration emitted by the vibrator drives the entire device to vibrate, preventing the vegetable oil from sticking to the inner wall of the preheating tank and the surface of the spiral heat-conducting tube, making it easy to discharge.

[0016] like Figure 1 and Figure 3As shown, a purification device for vegetable oil processing includes a filter tank 1 and a stabilizing assembly 2. The filter tank 1 has a discharge port 10 at its lower end. The stabilizing assembly 2 is installed inside the filter tank 1, above it. A fine filter cartridge 3 is installed inside the stabilizing assembly 2, a scraper assembly 5 is installed inside the fine filter cartridge 3, and a coarse filter cartridge 4 is installed inside the scraper assembly 5. A rotating shaft 6 is welded to the lower part of the coarse filter cartridge 4, and a bevel gear assembly 7 is installed at the lower end of the rotating shaft 6. The stabilizing assembly 2 includes a ring rail 201 and a pulley 202, with the pulley 202 slidably connected to the inner side of the ring rail 201. An isolation shell 8 is installed around the bevel gear assembly 7, and a motor 9 is installed at the right end of the bevel gear assembly 7. The opening of a regulating valve 11 controls the flow rate of the vegetable oil, which is injected into the filter tank 1 through a pipeline and then enters the coarse filter cartridge 4. The motor 9 drives the bevel gear assembly 7 to rotate the rotating shaft 6, which in turn generates centrifugal force between the coarse filter cartridge 4 and the fine filter cartridge 3, allowing the oil to quickly pass through the double filtration layers. Centrifugal force propels the filtered oil onto the inner wall of the tank, while the scraper assembly 5 and the rotating filter cartridge move relative to each other, continuously removing surface deposits. The top pulley 202 of the fine filter cartridge 3 runs stably along the ring rail 201, ensuring rotational accuracy. The isolation shell 8 effectively prevents the bevel gear assembly 7 from contacting the oil, and the synergistic effect of the vibrator 19 further promotes smooth discharge from the outlet 10.

[0017] like Figure 1 and Figure 2 As shown, a valve 11 is installed above the filter tank 1, and a preheating tank 12 is installed above the valve 11. A spiral heat-conducting pipe 16 is installed inside the preheating tank 12, and a circulation pump 13 is connected to the right side of the spiral heat-conducting pipe 16. A heater 14 is installed above the circulation pump 13, and a temperature sensor 15 is installed above the heater 14. A feed inlet 17 is installed on the upper left side of the preheating tank 12, and an air valve 18 is provided on one side of the feed inlet 17. A vibrator 19 is installed on the left side of the preheating tank 12, and the vibrator 19 is welded to the preheating tank 12. Vegetable oil is injected into the preheating tank 12 through the feed inlet 17. The air valve 18 automatically adjusts the air pressure inside and outside the tank to ensure smooth feeding. The circulation pump 13 drives the flow of the heat-conducting medium inside the spiral heat-conducting pipe 16, and the temperature is precisely controlled by the heater 14 after real-time monitoring by the temperature sensor 15. The uniformly distributed heat-conducting fins on the surface of the spiral pipe significantly improve heat exchange efficiency, enabling the vegetable oil to heat up rapidly and uniformly within the range of 15-18℃, effectively reducing kinematic viscosity. The vibrator 19, which starts synchronously, prevents grease from adhering to the tank wall and pipes through high-frequency vibration, ensuring that the material is smoothly transported to the downstream filtration process.

[0018] Working Principle: When using this purification device for vegetable oil processing, the vegetable oil is first injected into the preheating tank 12 through the feed inlet 17. The air valve 18 automatically adjusts the air pressure inside and outside the tank to ensure smooth feeding. The circulating pump 13 drives the heat transfer medium in the spiral heat-conducting tube 16 to flow. After real-time monitoring by the high-precision temperature sensor 15, the temperature is precisely controlled to 15-18℃ by the intelligent heater 14. The heat-conducting fins evenly distributed on the surface of the spiral tube greatly improve the heat exchange efficiency, allowing the vegetable oil to quickly reach its optimal fluidity. The vibrator 19, which starts synchronously, prevents the oil from adhering to the tank wall and pipes through high-frequency vibration, ensuring smooth material delivery to the downstream filtration process. After preheating is completed, the opening of the regulating valve 11 controls the flow rate of the vegetable oil, which is injected into the filter tank 1 through the pipe and then enters the coarse filter cylinder 4. The motor 9 drives the bevel gear set 7 to rotate the rotating shaft 6, which in turn generates centrifugal force between the coarse filter cylinder 4 and the fine filter cylinder 3, allowing the oil to quickly pass through the double filtration layers. Centrifugal force propels the filtered oil onto the inner wall of the tank, while the scraper assembly 5 and the rotating filter cartridge move relative to each other, continuously removing surface deposits. The top pulley 202 of the fine filter cartridge 3 runs stably along the ring rail 201, ensuring rotational accuracy. The isolation shell 8 effectively prevents the bevel gear assembly 7 from contacting the oil, and the synergistic effect of the vibrator 19 further promotes smooth discharge from the outlet 10.
