Description

Technical Field

[0001] This utility model relates to the field of rapeseed oil refining technology, and in particular to a refining device for selenium-enriched rapeseed oil. Background Technology

[0002] Rapeseed oil, also known as rapeseed oil, is an edible oil extracted from rapeseed. It is one of the main edible oils in my country, primarily produced in the Yangtze River basin and the southwest and northwest regions, and its production ranks first in the world.

[0003] After rapeseed oil extraction, the crude oil needs to be heated and stirred in a heating tank. Then, some auxiliary agents are added to the crude oil to degumm, deacidify, decolorize, and deodorize it. After that, the salt-refined rapeseed is filtered through a centrifugal oil filter to remove impurities, thus obtaining rapeseed oil with higher purity.

[0004] Crude oil still contains a lot of impurities after refining. If it is directly sent to a centrifugal oil filter for centrifugal filtration, the impurities will adhere to the inner surface of the centrifugal oil filter, making it inconvenient to clean later. Furthermore, if the centrifugal oil filter is not cleaned in time after a period of use, it will affect the filtering effect of the rapeseed.

[0005] Therefore, it is necessary to provide a refining apparatus for selenium-enriched rapeseed oil to solve the above-mentioned technical problems. Utility Model Content

[0037] The extraction assembly 15 includes an extraction device 151, the inlet of which is equipped with a connecting pipe 153, and the outlet of which is equipped with a discharge pipe 152.

[0045] The working principle of the oil refining device for selenium-enriched rapeseed oil provided by this utility model is as follows:

[0046] First, a filter box 11 is installed above the centrifugal oil filter 16 via two support frames 14. An oil inlet pipe 17 with a second valve 19 is installed below the filter box 11. The second valve 19 can be opened as needed to transport the pre-filtered rapeseed oil into the centrifugal oil filter 16. A filter tank 10 is installed on top of the filter box 11, and a conical filter bucket 23 is installed inside the filter tank 10. The conical shape of the filter bucket 23 reduces clogging. Simultaneously, a cleaning rack 23 rotates on the inner surface of the filter bucket 23, further reducing the probability of clogging. A filter pipe 18 is installed at the bottom of the filter tank 10 via an installation pipe 24, positioned inside the filter box 11. The rapeseed oil filtered twice by the filter bucket 23 and filter pipe 18 is transported through the oil inlet pipe 17 into the centrifugal oil filter 16 for final filtration. A pull-out component 15 is installed at one end of the filter pipe 18 for cleaning the filter. Inside the filter tube 18 of the box 11, after the crude oil is refined in the oil refining tank 6, the rapeseed oil is conveyed to the filter tank 10 through the conveying component 2. The filter hopper 23 filters out larger impurities for the first time. During this process, the cleaning frame 22 rotates continuously to assist in filtration. The rapeseed oil after the first filtration is conveyed to the filter tube 18 through the installation pipe 24. Some impurities will flow into the filter tube 18, while the rapeseed oil will be discharged from the filter tube 18 into the filter box 11. At the same time, opening the second valve 19 can convey the rapeseed oil to the centrifugal oil filter 16 for final filtration. If it is necessary to clean the filter tube 18, simply close the second valve 19, open the extraction component 15, and the impurities inside the filter tube 18 can be extracted. After completion, close the extraction component 15 and open the second valve 19 to convey the rapeseed oil normally into the centrifugal oil filter 16. Manual cleaning of the impurities inside the filter hopper 23 is only required periodically.

[0047] Compared with related technologies, the oil refining device for selenium-enriched rapeseed oil provided by this utility model has the following beneficial effects:

[0048] To reduce the amount of impurities from the rapeseed directly entering the centrifugal oil filter 16, a filter box 11 is first installed above the centrifugal oil filter 16 via two support frames 14. An oil inlet pipe 17 with a second valve 19 is installed below the filter box 11. Opening the second valve 19 allows the pre-filtered rapeseed to be transported into the centrifugal oil filter 16 as needed. A filter tank 10 is installed on top of the filter box 11, and a conical filter bucket 23 is installed inside the filter tank 10. The conical shape of the filter bucket 23 reduces clogging. Simultaneously, a cleaning rack 23 rotates on the inner surface of the filter bucket 23, further reducing the probability of clogging. A filter tube 18 is installed at the bottom of the filter tank 10 via an installation pipe 24, so that the filter tube 18 is located inside the filter box 11. The rapeseed oil filtered twice by the filter bucket 23 and the filter tube 18 is transported to the centrifugal oil filter 16 through the oil inlet pipe 17 for final filtration. One end of the filter tube 18 is equipped with an extraction component 15, which can clean the filter tube 18 inside the filter box 11. Through this structure, the rapeseed oil entering the centrifugal oil filter 16 can be filtered twice, reducing the number of impurities entering the centrifugal oil filter 16, thus reducing the number of times the centrifugal oil filter 16 needs to be cleaned. The filter tube 18 can be cleaned automatically, and the filter bucket 23 can be removed for easy cleaning.
