Description

Technical Field

[0001] This utility model relates to a self-cleaning filter device for soybean oil production, belonging to the technical field of filter devices. Background Technology

[0002] In the soybean oil production process, filtration is a crucial step in ensuring oil quality. Traditional soybean oil filtration devices mostly employ plate and frame, bag, or cartridge filter structures, using filter cloth, filter paper, and other filter media to intercept impurities in the soybean oil, such as soybean hulls, soybean meal fragments, phospholipids, and other suspended solids.

[0003] Chinese patent publication (publication number: CN215013410U) discloses an automatic cleaning device for soybean oil production, including a cleaning tank. The lower end of the cleaning tank is equipped with a receiving box and a water filter box on both sides. A motor is fixedly installed on the upper surface of the cleaning tank. Several stirring blades are fixedly installed on the output end of the motor through a stirring shaft. At the same time, the soybeans rub against the inner wall of the spiral feeding pipe under the action of water flow, resulting in good soybean cleaning effect and continuous soybean cleaning, which improves soybean cleaning efficiency. The wastewater after cleaning soybeans is filtered through a filter screen to reduce water waste. The device can also be operated by a water pump, using water to spray from the spray nozzle for convenient cleaning of the inside of the cleaning tank.

[0004] The aforementioned device employs a simple backwashing structure, utilizing water or oil flow to impact the surface of the filter medium in the opposite direction. However, this method has limited effectiveness in removing stubbornly attached impurities, especially viscous substances such as phospholipids and sludge, which are difficult to remove effectively.

[0005] Therefore, a self-cleaning filtration device for soybean oil production is proposed. Utility Model Content

[0030] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] Example 1

[0033] like Figure 1-6 As shown, this utility model embodiment provides a self-cleaning filter device for soybean oil production, including: equipment component 1, a filter component 2 is provided at the inner end of the equipment component 1, a self-cleaning component 3 is provided at the upper end of the filter component 2, and a linkage component 4 is provided below the self-cleaning component 3.

[0034] The equipment component 1 includes an oil filter frame 100, an oil outlet valve 101 is fixedly connected to the lower front end of the oil filter frame 100, a sealing tank cover 102 is installed on the upper end of the oil filter frame 100, and a locking rotating rod 103 is provided at each of the four corners of the outer end of the sealing tank cover 102.

[0035] The filter assembly 2 includes a filter screen plate 200, which is disposed on the upper side of the inner end of the oil filter frame 100. A replaceable perforated filter paper 201 is connected to the upper end of the filter screen plate 200, and an inner hollow pressing ring 202 is placed on the outer side of the upper end of the replaceable perforated filter paper 201.

[0036] The self-cleaning assembly 3 includes an annular electric guide rail 300 opened inside the inner hollow pressing ring 202. A magnetic slider 301 is fixedly connected to the output end of the annular electric guide rail 300. A detachable central column 302 is fixedly connected to the middle of the filter screen plate 200. A metal linkage crossbar 304 is fixedly connected to the outer side of the detachable central column 302. A pair of hinges 305 are fixedly connected to the lower end of the metal linkage crossbar 304.

[0037] A silicone adapter scraper 306 is installed at the lower end of the hinge 305. A serrated strip 307 is provided at the lower end of the silicone adapter scraper 306. The serrated strip 307 is in contact with the replaceable perforated filter paper 201. The magnetic slider 301 is magnetically connected to the metal linkage crossbar 304. A motor 303 is fixedly connected to the upper end of the sealed can lid 102. The output end of the motor 303 is connected to the detachable central shaft column 302.

[0038] By setting up a combination of a filter screen plate 200 and a replaceable perforated filter paper 201, impurities in soybean oil can be effectively intercepted, ensuring filtration accuracy. The silicone adapter scraper 306 in the self-cleaning component 3 works in conjunction with the serrated strip 307 to specifically scrape off impurities accumulated on the surface of the filter paper, avoiding filter clogging and maintaining filtration efficiency.

[0039] Example 2

[0040] like Figure 2-5 As shown, in one embodiment, the linkage component 4 includes a connecting rod 400, which is disposed in the middle of the filter screen plate 200 and connected to the detachable central column 302. The lower end of the connecting rod 400 is provided with an extension rotating rod 401. The outer end of the extension rotating rod 401 is fixedly connected to a plurality of transverse support rods 402. The ends of the plurality of transverse support rods 402 away from the extension rotating rod 401 are fixedly connected to an inner wall auxiliary scraper 403. The inner wall auxiliary scraper 403 is in contact with the inner sidewall of the oil filter frame 100.

[0041] By setting the inner wall auxiliary scraper 403 to rotate against the inner wall of the oil filter frame 100 under the drive of the linkage component 4, impurities on the inner wall of the frame are removed. The inner wall auxiliary scraper 403 cleans the surface of the inner wall of the equipment, realizing synchronous cleaning of different parts inside the device, avoiding the impact of impurities on oil quality, reducing manpower input, and improving cleaning efficiency and production continuity.

[0042] In operation, this invention works as follows: After soybean oil enters the oil filter frame 100, it is first filtered through the filter screen plate 200 and the replaceable perforated filter paper 201. Impurities are trapped on the surface of the filter paper, and the filtered soybean oil flows out from the oil outlet valve 101. When self-cleaning is required, the motor 303 on the sealed tank cover 102 is activated, driving the detachable central shaft column 302 to rotate. When the detachable central shaft column 302 rotates, it drives the extension rotating rod 401 and the transverse support rod 402 to rotate through the connecting rod 400, causing the inner wall auxiliary scraper 403 to rotate along the inner wall of the oil filter frame 100, scraping off the impurities attached to the inner wall of the frame. At the same time, the rotation of the detachable central shaft column 302 drives the metal linkage crossbar 304 to rotate. Since the magnetic slider 301 is magnetically connected to the metal linkage crossbar 304, the circumferential electric guide rail 300 drives the magnetic slider 301 to move along the guide rail, driving the metal linkage crossbar 304. While rotating, the device moves along the guide rail. The non-rigid connection reduces the impact of oil on the annular electric guide rail 300, thus ensuring its service life. The metal linkage crossbar 304 drives the silicone adapter scraper 306 through the hinge 305. The serrated strip 307 at the lower end of the silicone adapter scraper 306 contacts the surface of the replaceable perforated filter paper 201, scraping away impurities on the filter paper surface during the movement, thus cleaning the filter assembly 2. The entire self-cleaning process is driven by the motor 303 and uses magnetic connection and guide rail linkage to achieve synchronous cleaning of different parts inside the device, ensuring continuous and efficient operation of the device. The cleaning of the inner wall and the cleaning of the filter assembly 2 are carried out simultaneously, forming a comprehensive cleaning of the inside of the device. After self-cleaning, the amount of impurities remaining inside the device is greatly reduced, effectively reducing the pressure of the subsequent water cleaning process and reducing the amount of cleaning agent used and wastewater generated.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
