Description

Technical Field

[0001] This application relates to the field of soybean oil processing technology, and more specifically, to a filtration device for soybean oil processing. Background Technology

[0002] In the soybean oil production and processing, the effective removal and filtration of impurities (such as phospholipids, protein fragments, and suspended particles) contained in the crude oil after extraction is a key processing technology. The filtration effect directly affects the quality and stability of the finished oil. Existing technologies typically use single-stage filters for coarse separation of impurities, resulting in insufficient filtration precision. This leaves residue structures in the soybean oil, and the impurities inside the filtration equipment are not easy to clean. After a period of use, grease and oil stains easily form and cause blockages, making it impossible to achieve dynamic scraping operations in continuous production. This leads to high oil loss rates, low oil yields, low cleaning efficiency, and frequent downtime for maintenance, increasing disassembly and assembly time and production costs. In view of this, we propose a filtration device for soybean oil processing. Utility Model Content

It achieves preliminary solid-liquid separation through the coordinated design of multi-stage filtration and a rotating scraping mechanism. The upper spherical filter cover completes the initial solid-liquid separation, and the fine filter element of the secondary filter achieves the interception of micron-level impurities, ensuring improved oil clarity. The oil scraper rotates along the inner wall of the lower shell, which can remove residual oil and impurities attached to the lower shell during the production filtration process, avoiding production interruptions caused by manual disassembly and cleaning. The whole device is easy to assemble, making the multi-stage filtration structure easy to disassemble, clean or replace, keeping the filtration device clean, and improving the technical effect of soybean oil production quality.

[0031] Reference Figures 1 to 4 This application provides a filtering device for soybean oil processing, comprising: an oil receiving shell 1, which is detachably connected to an upper shell 11 and a lower shell 12. An annular limiting ring 111 is fixedly provided inside the upper shell 11. An upper spherical filter cover 2 is placed and installed on the upper surface of the annular limiting ring 111.

[0032] The rotating mechanism 5 includes a motor 51, which is fixedly mounted on the bottom surface of the spherical base cover 121. The output end is connected to a drive pipe 52. Three oil scraping plates 53 are fixedly mounted on the drive pipe 52 along its circumference. These scraping plates 53 rotate and adhere to the inner walls of the lower shell 12 and the spherical base cover 121. The drive pipe 52 is detachably connected to the secondary filter 6. The outer shell structure of this filtration device consists of an upper shell 11 and a lower shell 12, which are detachably connected to form an oil receiving shell 1. An upper spherical filter cover 2 can be inserted into the upper shell 11. The upper spherical filter cover 2 can achieve the initial screening purpose of solid-liquid separation and can be easily removed from the upper shell 11 for cleaning or replacement. The soybean oil that has passed the initial screening is conveyed to the riser 71 via a conical oil guide shell 7, and then... 1. The oil is introduced into the secondary filter 6 for secondary fine filtration. The output end of the motor 51 drives the oil scraper 53 and the secondary filter 6 to rotate at high speed through the drive tube 52. This allows the secondary filter 6 to centrifugally remove the absorbed soybean oil, reducing the amount of soybean oil adsorbed by the filter element in the secondary filter 6 and increasing the oil yield. The secondary filter 6 can be easily and quickly disassembled and installed. The oil scraper 53 rotates along the inner wall of the lower shell 12, which can remove residual oil and impurities adhering to the inner wall of the lower shell 12 during the production filtration process. This avoids production interruptions caused by manual disassembly and cleaning. The overall design is simple and reasonable, which shortens the filter screen replacement time, facilitates maintenance and cleaning, prevents oil stains from forming grease inside, keeps the filtration device clean, and improves the quality of soybean oil production.

The four self-locking casters 31 rotatably installed on the support frame 3 make the whole device easy to move and adapt to the needs of rapid transfer between different workstations in the workshop.

[0034] Reference Figure 1 and Figure 2 The oil drain pipe 4 has an L-shaped structure, and a ball valve 41 is rotatably installed on the oil drain pipe 4. The filtered soybean oil can be discharged and collected by setting the oil drain pipe 4, while the ball valve 41 allows the filtered soybean oil to be temporarily stored during the relocation of the whole device.

[0035] Reference Figure 2 and Figure 3 The upper spherical filter cover 2 is fixedly provided with a conical ring 22 along its edge. The conical ring 22 fits against the inner wall of the upper shell 11. A retaining ring 23 is fixedly provided on the bottom surface of the conical ring 22. The retaining ring 23 is inserted into the annular limiting ring 111. A lifting rod 21 is fixedly provided on the upper spherical filter cover 2. The conical ring 22 fits against the inner wall of the upper shell 11 to ensure airtightness. The retaining ring 23 is inserted into the annular limiting ring 111, so that the upper spherical filter cover 2 can be easily lifted, disassembled and installed by installing the lifting rod 21.

[0036] Reference Figure 2 and Figure 3 The annular limiting ring 111 has a concave cross-section and multiple limiting grooves 112 are provided along the circumference of the annular limiting ring 111. The retaining ring 23 is fixed with a limiting block structure that matches the limiting grooves 112 along the bottom surface of the circumference. The retaining ring 23 engages with the limiting grooves 112 of the annular limiting ring 111 through the limiting block, so that the upper spherical filter cover 2 is radially positioned after installation.

[0037] Reference Figure 2 and Figure 4 The oil scraper 53 is composed of an integrally fixed connection of a vertical plate and an arc plate, which enables the oil scraper 53 to scrape the oil film on the inner wall of the lower shell 12 and the spherical bottom cover 121 and discharge it through the oil drain pipe 4. The oil scraper 53 is made of 304 stainless steel and is mirror polished to reduce the coefficient of friction.

[0038] Reference Figure 2 and Figure 4 The secondary filter 6 includes a hollow metal cylinder 61 and a fine filter element 62. The fine filter element 62 is fixedly positioned inside the hollow metal cylinder 61. A convex rotating ring 72 is rotatably sleeved on the outside of the riser 71. Multiple screws are threadedly fixed to the upper end of the hollow metal cylinder 61 and the convex rotating ring 72. The oil inlet of the fine filter element 62 is inserted into the bottom end of the riser 71. A spline shaft 611 is fixedly provided on the bottom surface of the hollow metal cylinder 61. The spline shaft 611 is inserted and connected to the drive tube 52. The hollow metal cylinder 61 is formed by welding a perforated mesh plate and reinforcing ribs. The built-in fine filter element 62 uses gradient pore size pleated filter media. The hollow metal cylinder 61 and the spline shaft 611 achieve gapless transmission with the drive tube 52.

[0039] Working principle: During soybean oil processing, the crude oil to be processed is injected into the upper spherical filter cover 2 from the top port of the oil receiving shell 1. The oil is evenly spread on the surface of the upper spherical filter cover 2, intercepting large particles of impurities. These particles then slide down the conical surface of the conical oil guide shell 7 to the riser pipe 71. The pre-filtered oil flows along the riser pipe 71 into the fine filter element 62 located in the secondary filter 6. The output end of the motor 51 drives the drive pipe 52 to rotate, causing the three oil scraper blades 53 to scrape the oil film adhering to the inner wall of the lower shell 12 and the spherical bottom cover 121 into the oil discharge pipe 4. Meanwhile, the drive pipe 52, through the splined shaft 611, drives the hollow metal cylinder 61 and the fine filter element 62 to rotate at high speed, accelerating the adsorption of fine impurities by the fine filter element 62 and centrifugally ejecting the soybean oil to the lower shell 12. The inner wall of the spherical bottom cover 121 maximizes the oil yield and reduces the amount of soybean oil adsorbed by the fine filter element 62. The purified soybean oil flows out through the ball valve 41 on the L-shaped oil drain pipe 4, completing the continuous operation of the entire process. When maintenance is required, the upper shell 11 and the lower shell 12 can be disassembled. The upper spherical filter cover 2 can be easily removed from the upper shell 11 for cleaning or replacement. The secondary filter 6 can be removed as a whole by removing the screw between the convex rotating ring 72 and the hollow metal cylinder 61. The overall design is simple and reasonable, easy to maintain and clean, avoids the formation of grease inside the filter, keeps the filter device clean, and improves the quality of soybean oil production.
