Abstract
Description
Technical Field
[0001] This utility model relates to the field of centrifuge technology, specifically a material filtration centrifuge for the production and preparation of fine chemicals. Background Technology
[0002] Centrifugal separation technology is a method of separation based on the different centrifugal forces experienced by substances in a centrifugal field. In the production of fine chemicals, it is often necessary to separate solids from liquids in raw materials or reaction products to obtain pure products or raw materials for further processing. Filter centrifuges, as an application of centrifugal separation technology, have advantages such as high efficiency, speed, and continuous operation, and are particularly suitable for processing materials such as suspensions or emulsions. With the rapid development of the chemical industry, the requirements for the quality and purity of fine chemicals are becoming increasingly stringent, and traditional filtration and separation methods are no longer sufficient to meet production demands. Therefore, filter centrifuges, as an advanced separation device, have been widely used in the production of fine chemicals. They can not only achieve solid-liquid separation but also perform fractional separation based on particle size, further improving the purity and quality of the products.
[0003] Chinese Patent No. CN214637349U discloses a material filtration centrifuge for the production and preparation of fine chemicals, including a shell, a positioning seat, and a mounting seat. A rotary motor is installed at the middle position of the bottom of the shell. A discharge port is provided at the bottom of one side of the shell. A top cover is installed at the top of the shell, and a purification mechanism is provided on the side of the top of the top cover near the discharge port. A connecting shaft is installed at the middle position of the bottom of the shell, and the bottom end of the connecting shaft is fixedly connected to the output shaft of the rotary motor through a coupling. A positioning seat is installed at the top of the connecting shaft, and a first centrifuge cylinder is installed at the top of the positioning seat. Mounting seats are installed at the top of both sides of the first centrifuge cylinder, and a second centrifuge cylinder is installed between the mounting seats. A connecting block is installed on the outside of the first centrifuge cylinder. A connecting seat is installed inside the shell, and a receiving groove is provided at the top of the connecting seat. Ball bearings are evenly arranged inside the receiving groove.
[0004] The above technical solution has the following drawbacks: The equipment adopts a double-layer centrifuge cylinder structure, that is, a second centrifuge cylinder is installed at the top of both sides inside the first centrifuge cylinder, and the connecting shaft, positioning seat and other components are nested within each other. This complex structure causes the filter screen to be surrounded by layers. When it is necessary to clean the centrifuge cylinder, it is difficult for the staff to directly access the centrifuge cylinder. Many parts must be disassembled to approach the centrifuge cylinder, which is not only cumbersome to operate, but also easy to damage other parts of the equipment during the disassembly process.
[0005] To address these issues, we propose a material filtration centrifuge for the production and preparation of fine chemicals. Utility Model Content

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] Example 1:
[0027] To ensure efficient and stable filtration of materials inside the filter cylinder, please refer to [link / reference needed]. Figures 1-5 This utility model provides a technical solution: a material filtration centrifuge for the production and preparation of fine chemicals, including a support frame 1, which provides a stable support foundation for the entire centrifuge, a cylinder 2 is provided above the support frame 1 as the main container for material filtration, a cylinder cover 201 is provided above the cylinder 2, and a material handling mechanism is provided on the cylinder cover 201.
[0028] The material handling mechanism includes a material filtration unit and a filter cake cleaning unit;
[0029] The material filtration unit includes a motor 301, a slanted disc distributor 302, a feed pipe 303, a third motor 801, a rotating shaft 802, a filter cartridge 803, filter holes 804, and an annular slider 805. An annular groove 202 is formed inside the upper part of the cylinder 2. The annular slider 805 is fixedly connected to the outer side of the upper part of the filter cartridge 803, and the annular slider 805 is slidably connected to the annular groove 202. The bottom of the filter cartridge 803 is fixedly connected to the top of the rotating shaft 802. Filter holes 804 are formed on the outer side of the filter cartridge 803. As the core component of filtration, the filter holes 804 on the surface of the filter cartridge 803 allow liquid to pass through, while solid particles are trapped on the inner wall of the filter cartridge, achieving solid-liquid separation of the material. The rotating shaft 802 passes through the bottom of the cylinder 2 and is connected to the third motor 801. The third motor 801 is fixedly connected to the bottom of the support frame 1, driving the rotating shaft 802 to rotate, which in turn drives the filter cartridge 803 to rotate at high speed, generating centrifugal force, causing the liquid in the material to be thrown out through the filter holes 804, achieving the filtration purpose. Motor 301 is fixedly connected to the top of the cylinder cover 201 via an inclined support block. Motor 301 is connected to the inclined disc distributor 302, which rotates to evenly distribute the material on the surface of the filter cartridge 803, preventing material accumulation that could lead to poor filtration or uneven filter cake. One end of the feed pipe 303 is connected to the inclined disc distributor 302, serving as the channel for material to enter the centrifuge. The design of the feed pipe 303 facilitates a continuous and stable supply of material. The other end of the feed pipe 303 is located on the upper surface of the cylinder cover 201. A liquid outlet pipe 6 is fixedly connected at the gap between the filter cartridge 803 and the cylinder body 2, discharging the filtered liquid out of the centrifuge to ensure the continuity and efficiency of the filtration process. A discharge pipe 7 is fixedly connected at the bottom of the filter cartridge 803, corresponding to the position of the cylinder body 2, discharging the filtered solid material out of the centrifuge for subsequent processing.
[0030] Example 2:
[0031] To clean the filter cartridge and remove residues, the device includes a filter cake cleaning unit. This unit comprises a cleaning assembly and a scraping assembly. The cleaning assembly includes a washing pipe 501 and a water spray pipe 502. The washing pipe 501 is fixedly connected to the cartridge cover 201, and multiple water spray pipes 502 are fixedly connected above the washing pipe 501. The washing pipe 501 is connected to an external water source via a pipe. As a core component of the cleaning assembly, the washing pipe 501 is responsible for introducing external water into the device. Its fixed connection to the cartridge cover 201 ensures a stable and accurate delivery of the cleaning solution to the water spray pipes 502. Through the introduction of the washing pipe 501, the cleaning solution can be evenly sprayed onto the filter cartridge 803 and the residues on it, effectively softening and removing the filter cake and impurities adhering to the inner wall of the filter cartridge, facilitating subsequent scraping operations.
[0032] The scraping assembly includes a support 401, a worm gear 402, a second motor 403, a connecting shaft 404, a scraper 405, a connecting rod 406, a connecting strip 407, and a worm 408. The support 401 is fixedly connected to the top of the cylinder cover 201. The middle part of the worm gear 402 is fixedly connected to the connecting shaft 404. The bottom of the connecting shaft 404 is fixedly connected to the connecting rod 406. One side of the connecting rod 406 is fixedly connected to one end of the connecting strip 407. The other end of the connecting strip 407 is fixedly connected to the scraper 405. Both ends of the worm 408 are connected between two supports. The output end of the second motor 403 is connected to the worm 408 through a coupling. The scraper 405 is attached to the inner wall of the filter cartridge 803. The cooperation between the worm gear 402 and the worm 408 enables the scraper 405 to rotate. When the filter cake needs to be cleaned, the scraper 405 is rotated by rotating the connecting shaft 404, so that the scraper 405 is attached to the inner wall of the filter cartridge 803.
[0033] Working Principle: Material enters the centrifuge through the feed pipe 303 and is evenly distributed on the surface of the filter cartridge 803 by the inclined disc distributor 302. Motor 3 801 drives the rotating shaft 802 to rotate, thereby causing the filter cartridge 803 to rotate at high speed. Under centrifugal force, the liquid in the material is thrown out through the filter holes 804 on the filter cartridge 803, achieving solid-liquid separation. The filtered liquid is discharged from the centrifuge through the liquid outlet pipe 6, while the solid material remains inside the filter cartridge 803. Filter Cake Cleaning: When cleaning of the filter cartridge 803 is required, the cleaning assembly is activated. The washing pipe 501 introduces external water into the device, which is evenly sprayed onto the filter cartridge 803 and the residue on it through the spray pipe 502. The cleaning solution softens and removes the filter cake and impurities adhering to the inner wall of the filter cartridge. The scraping assembly is activated, and motor 2 403 drives the worm gear 408 to rotate. The cooperation between the worm gear 408 and the worm wheel 402 enables the rotation of the connecting shaft 404. The connecting shaft 404 drives the scraper 405 to rotate via the connecting rod 406 and connecting strip 407, causing the scraper 405 to adhere to the inner wall of the filter cartridge 803. Then, the motor 801 is started to rotate the filter cartridge 803, scraping off the residual filter cake and impurities. The scraped material is discharged from the centrifuge through the discharge pipe 7.
