Description

Technical Field

[0001] This utility model relates to the field of oil-water separation technology, and in particular to an oil-water separation device for vegetable oil extraction. 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] According to the search, the patent (application number: 202321166374.1) discloses "an oil-water separation device for vegetable oil extraction". The device uses a vacuum pump connected to the air extraction pipe on the upper surface of the separation device to vacuum heat the water remaining in the separated oil, so that the water turns into steam and is extracted, which facilitates the thorough removal of the water remaining in the separated vegetable oil and improves the separation effect of the oil-water separation device.

[0004] However, like traditional devices, the above-mentioned device can only separate the oil-water mixture in the cylinder for that batch, which results in a long time for oil-water mixing, making it unsuitable for continuous oil-water separation and leading to low work efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides an oil-water separation device for vegetable oil extraction, which overcomes the shortcomings of the prior art and effectively solves the problem that the oil-water mixing time in the prior art is long, which is not conducive to continuous oil-water separation and results in low work efficiency.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An oil-water separation device for extracting vegetable oil includes a cylinder. A feeding mechanism is connected to the top of the cylinder. The feeding mechanism includes a cover plate, a servo motor mounted on the top of the cover plate, a rotating rod connected to one end of the output shaft of the servo motor, a feeding pipe inserted and fixed to one side of the top of the cover plate, a feeding hopper inserted and fixed to the top of the feeding pipe, and a filter cylinder inserted and fixed to the top of the feeding hopper. A drain pipe and an oil drain pipe are respectively inserted and fixed to the outer wall of the cylinder. A connecting frame is fixed to one side of the inner wall of the cylinder. A connecting rod is rotatably connected to the connecting frame. A round block is fixed to the bottom end of the connecting rod. Scrapers are fixed to the bottom of the round block at equal intervals.

[0008] By pouring an oil-water mixture into the feed hopper, the filter cylinder filters out large particles of impurities, improving the quality of oil-water separation. The oil-water mixture enters the cylinder through the feed pipe at the end furthest from the drain pipe. The oil floats to the top inside the cylinder. As the oil-water mixture continues to enter the cylinder, the oil and water levels inside the cylinder increase. When the liquid level inside the cylinder reaches the drain pipe's discharge level, the water inside the cylinder is discharged through the drain pipe. As the water is discharged, the proportion of oil in the cylinder increases, causing the minimum oil level to drop below the drain pipe. At this point, the control valve is opened, and the oil is discharged through the drain pipe. When the device has been used for a long time, small particles of impurities that cannot be filtered accumulate at the bottom of the cylinder. At this time, clean water is injected, and the servo motor drives the rotating rod and connecting rod to rotate, causing the circular block to drive the scraper to rotate and scrape the bottom of the cylinder. Pulling out the pipe plug allows the impurities and dirt inside the cylinder to be discharged, facilitating the cleaning of the bottom of the cylinder.

[0009] Preferably, a fixing ring is fitted and fixed to the outer wall of the cylinder, and a bracket is fixed to one end of the fixing ring, and a base is fixed to the bottom of the bracket.

[0010] The cylinder is raised by fixing rings, brackets and bases to facilitate the separation and discharge of oil and water.

[0011] Preferably, the rotating rod is rotatably connected to the cover plate, and a connecting groove is provided at the bottom of the rotating rod.

[0012] The servo motor drives the rotating rod to rotate.

[0013] Preferably, the bottom end of the feed pipe faces away from the bottom end of the drain pipe, and the bottom end of the feed pipe is higher than the bottom end of the drain pipe.

[0014] The oil-water mixture is injected into the cylinder through the feed pipe, away from the drain pipe, so that the oil can float smoothly in the cylinder and the water can be discharged from the drain pipe.

[0015] Preferably, the oil drain pipe is equipped with a control valve, and the top of the oil drain pipe is higher than the bottom of the feed pipe.

[0016] The oil drain pipe can be opened or closed by controlling the valve. Opening the control valve allows the oil in the cylinder to be discharged from the oil drain pipe.

[0017] Preferably, a connecting block is fixed to the top of the connecting rod, and the connecting block and the connecting groove form an insertion fit.

[0018] The connecting rod and the rotating rod are connected by a connecting block and a connecting groove. The rotating rod drives the connecting rod to rotate, which enables the scraper to scrape dirt from the bottom of the cylinder.

[0019] Preferably, a drain pipe is fixed to the bottom of the cylinder, and a pipe plug is inserted into the bottom of the drain pipe.

[0020] By pulling out the plug, impurities and dirt inside the cylinder can be discharged, making it easier to clean the bottom of the cylinder.

[0021] The beneficial effects of this utility model are as follows:

[0022] By pouring an oil-water mixture into the feed hopper, the oil floats to the top of the cylinder. As the oil-water mixture continues to enter the cylinder, the oil and water levels inside the cylinder increase. When the liquid level in the cylinder reaches the drain pipe's drain level, the water in the cylinder is discharged through the drain pipe. As the water is discharged, the proportion of oil in the cylinder increases, causing the minimum oil level to drop below the drain pipe. At this point, the control valve is opened, and the oil is discharged through the drain pipe. This effectively solves the problem of long mixing time in existing technologies, which is not conducive to continuous oil-water separation and leads to low work efficiency.

A drain pipe 12 and an oil drain pipe 13 are respectively inserted and fixed to the outer wall of the cylinder 1. A connecting frame 14 is fixed to one side of the inner wall of the cylinder 1. A connecting rod 15 is rotatably connected to the connecting frame 14. A round block 16 is fixed to the bottom end of the connecting rod 15. Scraper strips 17 are evenly distributed at the bottom of the round block 16.

[0031] A fixing ring 2 is fixedly fitted to the outer wall of the cylinder 1. A bracket 3 is fixed to one end of the fixing ring 2. A base 4 is fixed to the bottom of the bracket 3. The cylinder 1 is raised by the fixing ring 2, the bracket 3 and the base 4 to facilitate the separation and discharge of oil and water. The rotating rod 8 is rotatably connected to the cover plate 6. A connecting groove is opened at the bottom of the rotating rod 8. The servo motor 7 drives the rotating rod 8 to rotate. The bottom end of the feed pipe 9 faces away from the bottom end of the drain pipe 12. The bottom end of the feed pipe 9 is higher than the bottom end of the drain pipe 12. The oil-water mixture is injected into the cylinder 1 away from the drain pipe 12 through the feed pipe 9, so that the oil can float smoothly in the cylinder 1 and the water can be discharged from the drain pipe 12.

[0032] The oil drain pipe 13 is equipped with a control valve. The top of the oil drain pipe 13 is higher than the bottom of the feed pipe 9. The control valve opens and closes the channel of the oil drain pipe 13. Opening the control valve allows the oil in the cylinder 1 to be discharged from the oil drain pipe 13. The top of the connecting rod 15 is fixed with a connecting block. The connecting block and the connecting groove form an insertion fit. The connecting rod 15 and the rotating rod 8 are connected by the connecting block and the connecting groove.

By pulling out the pipe plug, impurities and dirt in the cylinder 1 can be discharged, which is conducive to cleaning the bottom of the cylinder 1.

[0033] Working principle:

[0034] During operation, an oil-water mixture is poured into the feed hopper 10. The filter cylinder 11 filters out large particles of impurities in the mixture, improving the quality of oil-water separation. The oil-water mixture enters the cylinder 1 through the feed pipe 9 at the end furthest from the drain pipe 12. The oil floats to the top inside the cylinder 1. As the oil-water mixture continuously enters the cylinder 1, the oil and water levels inside the cylinder 1 continuously increase. When the liquid level in the cylinder 1 reaches the drainage level of the drain pipe 12, the water in the cylinder 1 is discharged through the drain pipe 12. With the discharge of water, the oil in the cylinder... As the proportion of oil in body 1 increases, the lowest oil level drops below the drain pipe 13. At this time, the control valve is opened, and the oil is discharged through the drain pipe 13. When the device has been used for a long time, some small particles of impurities that cannot be filtered accumulate at the bottom of the cylinder 1. At this time, clean water is injected, and the servo motor 7 drives the rotating rod 8 and the connecting rod 15 to rotate, so that the round block 16 drives the scraper 17 to rotate and scrape the dirt at the bottom of the cylinder 1. Pulling out the pipe plug can discharge the impurities and dirt in the cylinder 1, which is conducive to cleaning the bottom of the cylinder 1.
