Description

Technical Field

[0001] This utility model relates to the field of purification equipment technology, specifically to a dynamic purification equipment for rapeseed oil. Background Technology

[0002] After nearly 10 years of effort, China has transformed traditional, low-quality, high-erucic acid rapeseed oil into low-erucic acid rapeseed oil, which boasts the best nutritional quality among major vegetable oils. By 2010, the rate of low-erucic acid rapeseed oil production in my country reached over 90%. The human body has a high absorption rate of rapeseed oil, reaching up to 99%. Rapeseed oil has certain effects on softening blood vessels and delaying aging. However, because pressed rapeseed oil still contains a large number of impurities, which darken its color and affect its quality, it needs to be filtered and purified. Currently, rapeseed oil is filtered using canvas. However, when impurities clog the canvas, the filtration speed decreases, thus reducing the purification efficiency.

[0003] In the prior art, such as the announcement number CN214991407U, a multi-stage separation and purification device for rapeseed oil production is proposed. This technical solution discloses a multi-stage separation and purification device for rapeseed oil production, including a housing. The housing has a first cavity inside, and a first rod is arranged in the middle of the first cavity. Filter discs are uniformly fixedly installed in the first cavity. Fixed sleeves are uniformly fixedly installed on the rod of the first rod. A connector is fixedly installed at the outer end of the fixed sleeve. A hollow sleeve is uniformly fixedly installed at the outer end of the connector. A spiral rod is arranged inside the hollow sleeve. The outer end of the spiral rod uniformly penetrates the outer end of the hollow sleeve and is fixedly installed with a helical gear. Annular grooves are uniformly formed on the wall of the first cavity, and helical toothed rings are uniformly fixedly installed in the annular grooves. This utility model, through the cooperation of helical gears, helical toothed rings, scrapers, fixed sleeves, connectors, filter discs, hollow sleeves, and spiral rods, achieves the scraping and collection of impurities on the top of the filter discs, improving the efficiency of rapeseed oil filtration and purification.

[0004] However, the existing rapeseed oil production purification equipment is an integrated unit, which makes it difficult for staff to clean and maintain the inside of the equipment. When the equipment becomes clogged or damaged after long-term use, it will affect the normal operation of the equipment.

[0005] To address the aforementioned issues, this application proposes a dynamic purification and refining device for rapeseed oil. Utility Model Content

[0006] This utility model aims to provide a dynamic purification and refining device for rapeseed oil, mainly to solve the problem that the existing purification devices for rapeseed oil production are all integrated, which makes it difficult for workers to clean and maintain the inside of the device. After long-term use, blockages and damage to the inside of the device will affect its normal operation.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] The rapeseed oil dynamic purification equipment includes a housing with a detachable top cover. The outer wall of the top cover has a limiting component for fixing it. A servo motor is fixedly installed on the top of the top cover, and the output of the servo motor is fixedly connected to a rotating shaft. The rotating shaft passes through the top cover and is rotatably connected to it. A rectangular block is fixedly connected to the lower end of the rotating shaft. A rotating rod is rotatably connected to the bottom of the inner wall of the housing. The upper end of the rotating rod has a rectangular groove matching the rectangular block. Multiple fixed cylinders pass through the outer wall of the rotating rod, and the fixed cylinders are slidably connected to the rotating rod. A filter disc is fixedly connected to the outer wall of each fixed cylinder. A rotating cylinder is rotatably connected to the upper end of each fixed cylinder. Screws pass through the rotating cylinders and are threadedly connected to the rotating rod. A hollow sleeve is connected to the outer wall of the rotating cylinder via a connecting component.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working Principle: When this device operates, (a scraper is installed at the bottom of the hollow sleeve, which scrapes away oil residue and impurities from the top of the filter disc to prevent them from affecting the filtration speed of the filter disc; as the hollow sleeve rotates around the first rod, the oil residue and impurities rotate along with the scraper; when the oil residue and impurities rotate to the contact plate, which is set as an inclined surface, the oil residue and impurities will enter the interior of the hollow sleeve for collection during its rotation). (The part in parentheses refers to prior art, which is not elaborated upon in this application document. Further details are needed.) When cleaning the inside of the device, the top cover can be disassembled after releasing the limiting component. After removing the top cover, remove the screws on the rotating drum, and then pull the rotating drum upward to pull the filter disc and hollow sleeve out of the box. Then remove the hollow sleeve from the rotating drum. The device can then be cleaned or repaired. After cleaning or repair, fix the hollow sleeve to the rotating drum using the connecting component, and then fix the rotating drum to the outer wall of the rotating rod with screws. Finally, fix the top cover to the box using the limiting component. The device can then operate normally.

[0011] 2. Beneficial effects: The detachable top cover of the box allows for easy cleaning and maintenance of the interior. The rotating drum is fixed to the rotating rod with screws, and the hollow sleeve is fixed to the rotating drum with connecting components. This makes it easy to assemble and disassemble the rotating drum and the hollow sleeve. After the rotating drum and the hollow sleeve are removed, the cleaning and maintenance of the device becomes more convenient.

[0012] Preferably, the limiting component includes a first fixing block fixedly connected to the outer wall of the top cover, and the first fixing blocks are symmetrically arranged on the outer wall of the top cover. Symmetrical second fixing blocks are fixedly connected to the upper end of the outer wall of the housing. A sliding rod passes through the first fixing block, with a pressing block fixedly connected to the upper end of the sliding rod and an insert block fixedly connected to the lower end. A slot matching the insert block is opened at the top of the second fixing block. Sliding cavities are opened on both sides of the insert block, and a first wedge block is slidably connected inside each cavity. One side of the first wedge block extends out of the cavity, and a first spring is fixedly connected to the other side. The other end of the first spring is fixedly connected to the inner wall of the cavity. A groove matching the first wedge block is opened on the inner wall of the slot, and a button is slidably connected inside the groove. One side of the button extends... The second fixing block extends out and abuts against the first wedge block on the other side. The bottom of the first fixing block has a receiving groove that matches the insert block. Pressing the buttons on both sides of the second fixing block can push the first wedge block into the sliding cavity. When the first wedge block disengages from the sliding groove, the top cover can be removed. When installing the top cover, after placing the top cover on the box, pressing down the pressing block can move the insert block downward through the sliding rod. When the insert block is fully inserted into the slot, the first wedge block will pop out under the action of the first spring and engage with the sliding groove, thus completing the installation of the top cover. This not only makes the top cover more stable after installation, but also makes the top cover easier to install and remove, thereby facilitating the cleaning or maintenance of the inside of the box by the staff.

[0013] Preferably, the connecting assembly includes a connecting block fixedly connected to the outer wall of the rotating cylinder, a T-shaped block fixedly connected to one end of the hollow sleeve, a T-shaped groove matching the T-shaped block on the top of the connecting block, a cavity on the bottom of the T-shaped groove, a second wedge block slidably connected inside the cavity, a second spring fixedly connected to one side of the second wedge block, and the other end of the second spring fixedly connected to the inner wall of the cavity. After the rotating cylinder is removed from the box, the hollow sleeve is slid to move towards the connecting block, while the second wedge block is pushed to compress the second spring. After the hollow sleeve has moved to a certain extent, it can be disassembled by pulling it upwards. When installing the hollow sleeve, the T-shaped block at one end is inserted into the T-shaped groove on the connecting block. The T-shaped block will compress the inclined surface of the second wedge block to move it. When the T-shaped block moves to the bottom of the T-shaped groove, the second wedge block will push the hollow sleeve under the action of the second spring, moving it a certain distance, thus completing the installation of the hollow sleeve. This makes it more convenient for workers to clean the hollow sleeve.

[0014] Preferably, the screw is an embedded hexagonal design, and the outermost end of the screw is not higher than the outer wall of the rotating cylinder. After installation, the outermost end of the screw is not higher than the outer wall of the rotating cylinder, so that it will not protrude and cause wear. In addition, the screw is an embedded hexagonal design, which allows the screw to rotate better during installation and reduces the possibility of slippage.

[0015] Preferably, a third spring is fitted on the upper end of the outer wall of the slide rod. The upper end of the third spring is fixedly connected to the pressing block, and the lower end is fixedly connected to the first fixing block. When the buttons on both sides of the second fixing block are pressed to disengage the first wedge block from the slide groove, the slide rod will automatically move the insert block upward under the action of the third spring, without the need for manual pulling of the pressing block to move the insert block upward. This makes the disassembly of the top cover more convenient.

[0016] Preferably, a rubber ring is fixedly connected to the outer wall of the filter disc, and the rubber ring is set against the inner wall of the housing. After the filter disc is installed inside the housing, the rubber ring on the outer wall of the filter disc not only makes the filter disc better sealed after installation, but also effectively increases the friction between the filter disc and the inner wall of the housing. This can effectively prevent the filter disc from rotating with the rotating rod, thereby effectively ensuring the normal operation of the device.

[0017] Preferably, all corners at the top of the inner wall of the rectangular groove are chamfered. By chamfering all corners at the top of the inner wall of the rectangular groove, it is easier to insert the rectangular block into the rectangular groove when installing the top cover, thus making the installation of the top cover more convenient.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6The rapeseed oil dynamic purification equipment includes a housing 1. A top cover 2 is detachably connected to the top of the housing 1. The outer wall of the top cover 2 is equipped with a limiting component for fixing it. The top cover 2, being detachable from the top of the housing 1, allows for easy cleaning and maintenance of the interior of the housing 1. A servo motor 3 is fixedly installed on the top of the top cover 2. The output of the servo motor 3 is fixedly connected to a rotating shaft 4, which passes through the top cover 2 and is rotatably connected to it. The lower end of the rotating shaft 4 is fixedly connected to... A rectangular block 6 is rotatably connected to the bottom of the inner wall of the housing 1, and a rotating rod 5 is rotatably connected to it. The upper end of the rotating rod 5 has a rectangular groove 7 that matches the rectangular block 6. After the servo motor 3 is powered on, starting the servo motor 3 will cause the rotating rod 5 to rotate. The corners at the top of the inner wall of the rectangular groove 7 are all chamfered, which makes it easier to insert the rectangular block 6 into the rectangular groove 7 when installing the top cover 2, thus making the installation of the top cover 2 easier. Multiple fixing cylinders 8 pass through the outer wall of the rotating rod 5, and the fixing cylinders 8 are slidably connected to the rotating rod 5. The outer wall of the fixing cylinders 8 is fixedly connected to... A filter disc 9 is provided, and a rubber ring 31 is fixedly connected to the outer wall of the filter disc 9. The rubber ring 31 is set to abut against the inner wall of the housing 1. This not only makes the filter disc 9 more airtight after installation, but also effectively increases the friction between the filter disc 9 and the inner wall of the housing 1. This effectively prevents the filter disc 9 from rotating with the rotating rod 5, thus ensuring the normal operation of the device. A rotating cylinder 10 is rotatably connected to the upper end of the fixed cylinder 8. A screw 11 passes through the rotating cylinder 10 and is threadedly connected to the rotating rod 5. The rotating cylinder 10 is connected to the rotating rod 5 by the screw. Screw 11 is fixed on rotating rod 5, which makes it easier to disassemble and assemble rotating cylinder 10. Screw 11 is an embedded hexagonal screw, which allows for better rotation during installation and reduces the possibility of slippage. The outermost end of screw 11 does not protrude above the outer wall of rotating cylinder 10, so that screw 11 will not protrude and cause wear after installation. Hollow sleeve 12 is connected to the outer wall of rotating cylinder 10 through connecting assembly. Hollow sleeve 12 is fixed to rotating cylinder 10 through connecting assembly, which makes it easier to disassemble and assemble hollow sleeve 12.

[0027] like Figure 2 and Figure 3As shown, the limiting assembly includes a first fixing block 13 fixedly connected to the outer wall of the top cover 2, and the first fixing blocks 13 are symmetrically arranged on the outer wall of the top cover 2. A symmetrical second fixing block 32 is fixedly connected to the upper end of the outer wall of the box 1. A slide rod 14 passes through the first fixing block 13. A pressing block 15 is fixedly connected to the upper end of the slide rod 14, and an insert block 16 is fixedly connected to the lower end. A third spring 30 is sleeved on the upper end of the outer wall of the slide rod 14. The upper end of the third spring 30 is fixedly connected to the pressing block 15, and the lower end is fixedly connected to the first fixing block 13. A slot 17 matching the insert block 16 is opened on the top of the second fixing block 32. A sliding cavity 18 is opened on both sides of the insert block 16. A first wedge block 19 is slidably connected inside the sliding cavity 18. One side of the first wedge block 19 extends out of the sliding cavity 18, and a first spring 20 is fixedly connected to the other side. The other end of the first spring 20 is fixedly connected to the inner wall of the sliding cavity 18. A slot 17 matching the first wedge block 19 is opened on the inner wall of the slot 17. The slide groove 21 has a button 22 slidably connected inside. One side of the button 22 extends into a second fixing block 32, and the other side abuts against the first wedge block 19. The bottom of the first fixing block 13 has a receiving groove 23 that matches the insert block 16. Pressing the buttons 22 on both sides of the second fixing block 32 can push the first wedge block 19 into the slide cavity 18. When the first wedge block 19 is disengaged from the slide groove 21, the top cover 2 can be disassembled. When installing the top cover 2, after placing the top cover 2 on the box body 1, pressing down the pressing block 15 can drive the insert block 16 to move downward through the slide rod 14. When the insert block 16 is fully inserted into the slot 17, the first wedge block 19 will pop out under the action of the first spring 20 and engage with the slide groove 21, thus completing the installation of the top cover 2. This not only makes the top cover 2 more stable after installation, but also makes the top cover 2 easier to disassemble and assemble, thereby facilitating the cleaning or maintenance of the inside of the box body 1 by the staff.

[0028] like Figure 2 and Figure 6As shown, the connecting assembly includes a connecting block 24 fixedly connected to the outer wall of the rotating cylinder 10, a T-shaped block 25 fixedly connected to one end of the hollow sleeve 12, a T-shaped groove 26 matching the T-shaped block 25 opening at the top of the connecting block 24, a cavity 27 opening at the bottom of the T-shaped groove 26, a second wedge block 28 slidably connected inside the cavity 27, a second spring 29 fixedly connected to one side of the second wedge block 28, and the other end of the second spring 29 fixedly connected to the inner wall of the cavity 27. After the rotating cylinder 10 is removed from the box 1, the hollow sleeve 12 is slidably moved toward the connecting block 24, while simultaneously pushing the second wedge block. 28 compresses the second spring 29, and after the hollow sleeve 12 moves to a certain extent, it can be disassembled by pulling the hollow sleeve 12 upward. When installing the hollow sleeve 12, insert the T-shaped block 25 at one end into the T-groove 26 on the connecting block 24. The T-shaped block 25 will compress the inclined surface of the second wedge block 28 to make it move. When the T-shaped block 25 moves to the bottom of the T-groove 26, the second wedge block 28 will push the hollow sleeve 12 under the action of the second spring 29, making it move a certain distance, thus completing the installation of the hollow sleeve 12. This makes it more convenient for workers to clean the hollow sleeve 12.

[0029] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0030] When the device is in operation, the power supply is turned on and the servo motor 3 is started. (A scraper is provided at the bottom of the hollow sleeve. The scraper removes oil residue and impurities from the top of the filter disc to prevent them from affecting the filtration speed of the filter disc. When the hollow sleeve rotates around the first rod, the oil residue and impurities rotate with the scraper. When the oil residue and impurities rotate to the contact plate, the contact plate is set as an inclined surface, so the oil residue and impurities will enter the interior of the hollow sleeve for collection when the hollow sleeve rotates.) The part in parentheses is prior art. The document does not elaborate on this point. When cleaning the inside of the device, pressing the buttons 22 on both sides of the second fixing block 32 will push the first wedge block 19 into the sliding cavity 18. Once the first wedge block 19 disengages from the sliding groove 21, the top cover 2 can be disassembled. After removing the top cover 2, remove the screws 11 on the rotating drum 10. Then, pull the rotating drum 10 upwards to pull the filter disc 9 and the hollow sleeve 12 out of the housing 1. Then, slide the hollow sleeve 12 to move it towards the connecting block 24. Pushing the second wedge block 28 causes it to compress the second spring 29. After the hollow sleeve 12 moves to a certain extent, pulling it upwards allows for disassembly, making cleaning and maintenance of the device more convenient. After cleaning or maintenance, insert the T-shaped block 25 at one end of the hollow sleeve 12 into the T-groove 26 on the connecting block 24. The T-shaped block 25 will compress the inclined surface of the second wedge block 28, causing it to move. When the T-shaped block 25 moves to the bottom of the T-groove 26, the second wedge block 28 will press against the second spring 29. Under the action of 9, push the hollow sleeve 12 to move it a certain distance to complete the installation of the hollow sleeve 12. Then fix the rotating cylinder 10 to the outer wall of the rotating rod 5 with screws 11. Finally, after placing the top cover 2 on the box 1, press down the pressing block 15 to drive the insert block 16 to move downward through the slide rod 14. When the insert block 16 is fully inserted into the slot 17, the first wedge block 19 will pop out under the action of the first spring 20 and engage with the slide groove 21 to complete the installation of the top cover 2. The device can then operate normally.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
