Technical Field

[0001] This utility model belongs to the field of peanut oil filtration, specifically relating to a high-oleic peanut oil filtration device that facilitates the removal of impurities. Background Technology

[0002] High-oleic peanut oil is widely used in the edible oil industry due to its high nutritional value and strong oxidative stability. However, peanut oil is easily contaminated with impurities such as peanut shell fragments, phospholipid colloids, and mechanically abrasive particles during the pressing or extraction process. However, existing peanut oil filtration devices have a fixed single-layer filter screen pore size, which cannot simultaneously intercept large particles of impurities and ensure oil flow, leading to frequent clogging and reduced production efficiency.

[0003] The filter screen needs to be manually disassembled and cleaned, resulting in long downtime; some equipment uses fixed scrapers, which makes it difficult to remove deep-seated impurities from the filter screen. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, where peanut oil filtration devices, due to the fixed pore size of a single-layer filter screen, make it difficult to balance the interception of large particles and the flow rate of oil, resulting in frequent clogging and reduced efficiency. Furthermore, the reliance on manual disassembly and cleaning and the difficulty in removing deeply embedded impurities by fixed scrapers make it difficult to remove impurities. Thus, a high-oleic peanut oil filtration device that facilitates impurity removal is achieved.

[0005] To achieve the above-mentioned objectives, the technical solution of this utility model is: a high oleic acid peanut oil filtration device that facilitates impurity removal, comprising a filter box, wherein a feed pipe is connected to the top of the side wall of the filter box, and a primary filtration mechanism is snapped into the inside of the feed pipe; The filter box is fitted with a filter screen inside, and the filter screen is rotatably connected to a cleaning mechanism inside.

[0006] In the above-mentioned high oleic acid peanut oil filtration device that facilitates impurity removal, a support frame is fixedly connected to the outer surface of the filter screen, and the support frame is in contact with the inner wall of the filter box. A handle is fixedly connected to the top of the support frame, and the handle is used to pick up and put down the filter screen.

[0007] In the above-mentioned high oleic acid peanut oil filtration device that facilitates impurity removal, the top of the filter box is detachably connected to a top cover plate by bolts, and a drive motor is fixedly connected to the top of the top cover plate.

[0008] In the above-mentioned high oleic acid peanut oil filtration device that facilitates impurity removal, the cleaning mechanism includes a rotating shaft and a moving block, and the output shaft of the drive motor is fixedly connected to the top of the rotating shaft; The two sides of the rotating shaft are symmetrically fixedly connected with second support rods, and the outer surface of the second support rods is fitted with a return spring. One end of the reset spring is fixedly connected to the side wall of the movable block, and the other end abuts against the groove opened on the outer surface of the second support rod; The side wall of the movable block is provided with a limiting groove, and the second support rod is slidably connected in the limiting groove; A cleaning brush is attached to the other side of the movable block, and the cleaning brush is in contact with the inner wall of the filter screen.

[0009] In the above-mentioned high oleic acid peanut oil filtration device that facilitates impurity removal, a cross support frame is fixedly connected to the inner bottom wall of the support frame, and a bearing is fixedly connected to the middle position of the cross support frame. The bottom of the rotating shaft is fixedly connected to the inner ring of the bearing, thereby enabling the cleaning mechanism to rotate stably within the filter screen.

[0010] In the above-mentioned high oleic acid peanut oil filtration device that facilitates impurity removal, the primary filtration mechanism includes a first filter cover, a second filter cover, and a first support rod, wherein the first filter cover and the second filter cover are sequentially fixedly sleeved on the outer surface of the first support rod; The inner wall of the feed pipe is fixedly connected with a boss for supporting the second filter cover; A scraper is fixedly connected to the bottom of the outer surface of the second filter cover, and a rubber ring is adhered to the top of the outer surface of the second filter cover.

[0011] In the above-mentioned high oleic acid peanut oil filtration device that facilitates impurity removal, the diameter of the filter hole of the first filter cover is larger than the diameter of the filter hole of the second filter cover.

[0012] In the above-mentioned high oleic peanut oil filtration device that facilitates impurity removal, the bottom of the filter box is connected to a discharge pipe, and a solenoid valve is installed on the discharge pipe.

[0013] Compared with the prior art, the high oleic acid peanut oil filtration device of this utility model, which facilitates impurity removal, has at least the following beneficial effects: This utility model discloses a high-oleic peanut oil filtration device that facilitates impurity removal. It employs a three-stage filtration gradient formed by a primary filtration mechanism and a filter screen within the feed pipe, where the pore size of the first filter screen is greater than that of the second filter screen, which is greater than that of the filter screen. This design extends the impurity filtration path, ensuring that particles larger than 50μm are intercepted in the first and second stages, while fine particles are completely retained in the third-stage filter screen, thus improving efficiency compared to traditional single-stage filtration.

[0018] The high-oleic peanut oil filtration device of this utility model, which facilitates the removal of impurities, will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] This embodiment discloses a high-oleic peanut oil filtration device that facilitates impurity removal, referring to... Figure 1-6It mainly includes a filter box 1, with a feed pipe 4 connected to the top of the side wall of the filter box 1. A primary filtration mechanism 5 is snapped into the inside of the feed pipe 4. A filter screen 6 is snapped into the inside of the filter box 1, and a cleaning mechanism 7 is rotatably connected inside the filter screen 6. A discharge pipe 8 is connected to the bottom of the filter box 1, and a solenoid valve is installed on the discharge pipe 8.

[0021] The inclined feed pipe 4 is used for directional oil diversion, and the embedded snap-fit ​​primary filtration mechanism 5 forms the first impurity barrier; the core area of ​​the filter box 1 is equipped with a cylindrical filter screen 6 that can be quickly disassembled and installed, and its internal rotating cleaning mechanism 7 forms a dynamic cleaning system; the bottom of the box is equipped with a discharge pipe 8 controlled by a solenoid valve. The overall structure adopts a snap-fit ​​assembly process, which ensures sealing while facilitating component maintenance and replacement.

[0022] Reference Figure 1-3 A support frame 9 is fixedly connected to the outer surface of the filter screen 6. The support frame 9 fits against the inner wall of the filter box 1. A handle 10 is fixedly connected to the top of the support frame 9 for taking and putting away the filter screen 6. A top cover plate 2 is detachably connected to the top of the filter box 1 by bolts. A drive motor 3 is fixedly connected to the top of the top cover plate 2. The output shaft of the drive motor 3 passes through the top cover plate 2 and is connected to the cleaning mechanism 7 for transmission.

[0023] The outer surface of the filter screen 6 is tightly fitted to the inner wall of the filter box 1 via an annular support frame 9. This support frame uses a snap-fit ​​structure to enhance sealing, and its top is integrated with a U-shaped handle 10. The top of the filter box 1 is equipped with an openable and closable top cover 2, which is quickly connected to the box body via evenly distributed anti-loosening bolts, facilitating the inspection and maintenance of the internal mechanism. The surface of the top cover 2 integrates a drive motor 3, whose output shaft passes through the center of the cover plate via a precision bearing and is rigidly connected to the cleaning mechanism 7 via a keyway coupling.

[0024] Reference Figure 1-5 The cleaning mechanism 7 includes a rotating shaft 701 and a moving block 703. The output shaft of the drive motor 3 is fixedly connected to the top of the rotating shaft 701. Second support rods 702 are symmetrically fixedly connected to both sides of the rotating shaft 701. A return spring 704 is sleeved on the outer surface of the second support rod 702. One end of the return spring 704 is fixedly connected to the side wall of the moving block 703, and the other end abuts against the groove opened on the outer surface of the second support rod 702. A limit groove is opened on the side wall of the moving block 703. The second support rod 702 is slidably connected in the limit groove. A cleaning brush 705 is attached to the other side of the moving block 703. The cleaning brush 705 is attached to the inner wall of the filter screen 6.

[0025] A cross support frame 11 is fixedly connected to the inner bottom wall of the support frame 9, and a bearing is fixedly connected to the middle position of the cross support frame 11. The bottom of the rotating shaft 701 is fixedly connected to the inner ring of the bearing, so as to realize the stable rotation of the cleaning mechanism 7 within the filter screen 6.

[0026] The cleaning mechanism 7 adopts an adaptive fitting structure design. The drive motor 3 drives the rotating shaft 701 to generate circumferential motion through a rigid coupling, which drives the two sets of second support rods 702 to rotate synchronously. The outer surface of the support rod is nested with a moving block 703, which forms a sliding guide fit with the support rod through a precision limiting groove structure to ensure the stability of radial movement.

[0027] A double-ended return spring 704 is installed on the second support rod 702. One end is anchored to the side wall of the moving block 703, and the other end is embedded in the annular groove of the support rod. The spring preload ensures that the moving block 703 constantly presses the cleaning brush 705 tightly against the inner wall of the filter screen 6. This constant pressure mechanism can automatically compensate for brush wear, ensuring effective contact throughout the entire cycle, and achieves 360° cleaning in conjunction with the spiral brush layout.

[0028] The bottom of the support frame 9 integrates a cross support bracket 11, with a bearing embedded in its center. The bottom of the rotating shaft 701 is rigidly connected to the inner ring of the bearing through a spline structure, forming a double radial constraint. This design disperses the load-bearing pressure of the rotating components and effectively suppresses eccentric vibration during high-speed operation.

[0029] Reference Figure 1 and Figure 2 as well as Figure 6 The primary filtration mechanism 5 includes a first filter cover 501, a second filter cover 502, and a first support rod 503. The first filter cover 501 and the second filter cover 502 are sequentially and fixedly sleeved on the outer surface of the first support rod 503. A boss for supporting the second filter cover 502 is fixedly connected to the inner wall of the feed pipe 4. A scraper 504 is fixedly connected to the bottom of the outer surface of the second filter cover 502, and a rubber ring 505 is adhered to the top of the outer surface of the second filter cover 502. The diameter of the filter holes in the first filter cover 501 is larger than that in the second filter cover 502, and the diameter of the filter holes in the second filter cover 502 is larger than that in the filter screen 6, forming a three-stage progressive filtration structure.

[0030] The primary filtration unit 5 adopts a dual-layer progressive interception structure. When the oil flows in through the feed pipe 4, it first contacts the outer first filter cover 501, whose large-pore mesh effectively intercepts coarse particulate impurities such as peanut shell fragments, forming the first physical barrier. The inner second filter cover 502 forms a secondary filtration zone through boss positioning, with its pore size reduced to 1mm, which can capture phospholipid colloidal clusters and mechanically worn particles. The gravity of the oil accelerates the sedimentation and separation of impurities.

[0031] The bottom scraper 504 on the second filter cover 502 peels off impurities attached to the pipe wall in real time; the top rubber ring 505 forms a dynamic seal with the boss through elastic deformation.

[0032] The working principle of this utility model of a high-oleic peanut oil filtration device for easy impurity removal is as follows: When using this device, peanut oil is first fed through the feed pipe 4. The peanut oil first passes through the first filter cover 501 and the second filter cover 502, which can filter out larger impurities in the peanut oil. After filtration, the peanut oil flows into the interior of the filter screen 6. The first filter cover 501 and the second filter cover 502 can be removed from the feed pipe 4 for cleaning by pulling the first support rod 503. When removing them, the rubber ring 505 first cleans the inner wall of the feed pipe 4, and then the scraper 504 scrapes and cleans the inner wall of the feed pipe 4.

[0033] Peanut oil is filtered inside the filter screen 6. After filtration, the drive motor 3 can be started. The output shaft of the drive motor drives the rotating shaft 701 to rotate. The rotating shaft 701 drives the moving block 703 and the cleaning brush 705 to rotate and clean the inner wall of the filter screen 6. This can remove impurities that are blocked in the filter holes. The return spring 704 can push the moving block 703 to make the cleaning brush 705 fit more closely to the filter screen 6, increasing the cleaning force. The second support rod 702 moves inside the moving block 703 to support the moving block 703.
