Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, specifically to a centrifuge that can prevent adhesion to the inner wall. Background Technology

[0002] In the production and processing of rapeseed oil, centrifuges are needed for filtration, dehydration and separation of oil. Centrifuges are machines that use centrifugal force to separate the components in a mixture of liquid and solid particles or liquid and liquid. However, existing centrifuges still have certain defects in use, such as:

[0003] In existing centrifuges, rapeseed oil constantly impacts the inner wall of the centrifuge during centrifugation. However, rapeseed oil is viscous and tends to adhere to the inner wall after impact, making it difficult to remove and resulting in waste. Most existing centrifuges cannot prevent this adhesion to the inner wall. Furthermore, impurities in the rapeseed oil can easily clog the fine pores during centrifugation, causing blockages and affecting centrifugation. Most existing centrifuges cannot clean these blockages. Utility Model Content

[0026] 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.

[0027] Please see Figures 1-5This utility model provides a technical solution: a centrifuge with anti-adhesion inner wall, comprising: an outer casing 1, a sealing cover 2, a controller 3, and a drive motor 4; the upper surface of the outer casing 1 is abutted against the sealing cover 2 by a sealing gasket, the sealing cover 2 is snapped into the outer casing 1 by a buckle, one side of the outer casing 1 is connected to the controller 3 by a bracket, and the bottom of the outer casing 1 is connected to the drive motor 4 by a motor mount, the output end of the drive motor 4 penetrates the inner wall of the outer casing 1 and is connected to a centrifugal mechanism 5, and a scraping mechanism 6 is provided on the inner wall of the outer casing 1; the scraping mechanism 6 includes an inner toothed cover 601 rotatably connected to the lower part of the inner wall of the outer casing 1 by a sealed bearing, the inner toothed cover 601 being rotatably connected to the output end of the drive motor 4 by a sealed bearing, and the inner toothed cover 601... A horizontal plate 602 is bolted to one side, and the horizontal plate 602 abuts against the lower inner wall of the outer box 1 via a rubber strip. An electric slide rail 603 is bolted to the end of the horizontal plate 602 away from the inner gear cover 601. The electric slide rail 603 abuts against the inner wall of the outer box 1 via a rubber strip. A slide block 604 is slidably connected to the electric slide rail 603. Rubber pads 605 are connected above and below the slide block 604 and abut against the electric slide rail 603. A reduction motor 606 is connected to the bottom of the outer box 1 near the drive motor 4 via a motor mount. The output end of the reduction motor 606 passes through the inner wall of the outer box 1 and is connected to a gear 607 via a coupling. The gear 607 is meshed with the inner wall of the inner gear cover 601.

[0028] In practice, a rubber strip is attached to one side of the electric slide rail 603, which abuts against the inner wall of the outer casing 1 to scrape off materials. After the coil inside the electric slide rail 603 is energized, it drives the slide block 604 to slide on the electric slide rail 603. The reduction motor 606 is started, which drives the gear 607 to drive the inner gear cover 601 to rotate. When the inner gear cover 601 rotates, it drives the horizontal plate 602 and the electric slide rail 603 to rotate, scraping off the materials attached to the inner wall of the outer casing 1. Then, the electric slide rail 603 is started, which drives the slide block 604 and the rubber pad 605 to slide slowly downwards, scraping off the materials on the surface of the electric slide rail 603, so that the centrifuge is not stuck to the inner wall.

[0029] See Figures 1-3 , Figure 6 and Figure 7It is known that the centrifugal mechanism 5 includes an external rotor motor 501 whose output end of the drive motor 4 is connected by a pin. The upper surface of the external rotor motor 501 is connected to the centrifugal tank 502 by bolts. The upper surface of the sealing cover 2 is connected to the stirring motor 503 by a motor base. The output end of the stirring motor 503 passes through the inner wall of the sealing cover 2 and is connected to a scraper 504 by a coupling. The scraper 504 abuts against the inner wall of the centrifugal tank 502, and the bottom of the scraper 504 is inserted into the lower part of the inner wall of the centrifugal tank 502 by a rod. The outer side of the external rotor motor 501 is connected to a support arm 505 by screws. The upper part of the support arm 505 is rotatably connected to a spike roller 506. The spike roller 506 is engaged in the fine hole of the centrifugal tank 502. The upper part of the spike roller 506 is rotatably connected to a connecting piece 507. One side of the connecting piece 507 is connected to a ring 508. The ring 508 is rotatably connected to the outer side of the centrifugal tank 502.

[0030] In practice, the external rotor motor 501 is started to drive the support arm 505 to rotate. The support arm 505 drives the spiked roller 506 and the connecting plate 507 to rotate along the outside of the centrifuge barrel 502, which in turn drives the ring 508 to rotate on the centrifuge barrel 502. While the spiked roller 506 rotates along the outside of the centrifuge barrel 502, it pushes the impurities in the fine holes of the centrifuge barrel 502 into the centrifuge barrel 502. Then, the impurities are scraped away by the centrifuge barrel 502 driven by the stirring motor 503 to prevent the material from clogging the fine holes and affecting centrifugation, thus clearing the blockage of the centrifuge.

[0031] In summary: When using this centrifuge with anti-adhesion inner wall design, firstly, open the latch on one side of the outer casing 1, remove the sealing cover 2, and pour the oil-water mixture to be centrifuged into the centrifuge tank 502. Then, close the sealing cover 2 and secure it with the latch. Operate the controller 3 to start the drive motor 4, which drives the outer rotor motor 501 and the centrifuge tank 502 to rotate. This forces the oil-water mixture through the fine holes of the centrifuge tank 502 and impacts the inner wall of the outer casing 1, making the oil-water mixture into a easily separated suspension. Simultaneously, start the outer rotor motor 501 and the stirring motor 503, causing the spiked roller 506 to rotate along the outside of the centrifuge tank 502, pushing impurities from the fine holes of the centrifuge tank 502 into the centrifuge tank 502. Then, the oil and water mixture is scraped away and stirred by the centrifuge tank 502 to prevent the centrifuge tank 502 from clogging. Under the action of gravity, the suspended oil and water mixture forms a stratified sedimentation with oil on top and water below. The valve on one side of the outer box 1 is opened to discharge the oil and water separately. After discharge, a large amount of semi-finished oil adheres to the inner wall of the outer box 1. The geared motor 606 is started to drive the electric slide rail 603 to rotate, scraping off the semi-finished oil on the inner wall of the outer box 1. Then, the electric slide rail 603 is started to drive the slide block 604 and the rubber pad 605 to move downward, scraping off the semi-finished oil on the surface of the electric slide rail 603 and discharging it from the valve on one side of the outer box 1. The contents not described in detail in this description belong to the prior art known to those skilled in the art.

[0032] Although the present invention 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 technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
