Description

Technical Field

[0001] This utility model relates to the field of fine chemical preparation technology, specifically to a material filtration device for fine chemical preparation. Background Technology

[0002] Fine chemicals refer to chemical products that have specific application functions, are technology-intensive, highly commercialized, and have high added value. In the process of preparing fine chemicals, filtration devices are usually used to separate fine chemical materials, so as to facilitate the separation of materials of different sizes.

[0003] In the process of chemical material preparation, screening plates are currently used to filter and screen materials to ensure that the screened materials meet the required particle size. However, since the size of the holes on the screening plate is fixed, this may cause some problems in actual use. If the screening process needs to be adjusted according to the particle size of different materials, the screening plate with fixed hole size cannot provide flexible hole diameter adjustment, resulting in unsatisfactory screening effect. As a result, unsuitable material sizes may be mixed in, affecting the smooth progress of subsequent chemical preparation and processing. 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.

[0025] Please see Figures 1-5 As shown, a material filtration device for the preparation of fine chemicals includes a housing 1 and a protective door 2 installed on the front end of the housing 1 via a hinge. A feed inlet 3 is connected to the top of the housing 1, and a sealing cover 4 is rotatably connected to the top of the feed inlet 3 via a hinge. The device also includes:

[0026] The screening assembly 5, which is installed in the inner cavity of the housing 1, includes a filter plate 501 and a drive motor 502. The filter plate 501 is installed in the inner cavity of the housing 1, and one side of the drive motor 502 is fixedly connected to the filter plate 501.

[0027] The output shaft of the drive motor 502 is fixedly connected to a threaded rod 503. A threaded block 504 is threadedly connected to the surface of the threaded rod 503. An adjusting plate 505 is fixedly connected to one side of the threaded block 504. The bottom of the adjusting plate 505 is in contact with the surface of the filter plate 501. A limiting block 506 is fixedly connected to one side of the adjusting plate 505. A limiting groove 507 is inserted into the surface of the limiting block 506. The limiting groove 507 is opened in the inner cavity of the filter plate 501. Sliding sleeves 508 are fixedly connected to each of the four corners of the filter plate 501. A sliding rod 509 is fitted inside the inner cavity of the sliding sleeve 508. One side of the sliding rod 509 is fixedly connected to the inner wall of the housing 1. Springs 510 are fixedly connected to the opposite side of the sliding sleeve 508. The opposite sides of the spring 510 are fixedly connected to the slide rod 509. The surface of the filter plate 501 is provided with sieve holes 511 for filtering and screening chemical materials. A rotating motor 6 is fixedly connected to one side of the box body 1. The output shaft of the rotating motor 6 is fixedly connected to the rotating rod 7. An elliptical disk 8 is fixedly connected to one side of the rotating rod 7. A fixed rod 9 is rotatably connected to one side of the top of the elliptical disk 8. One side of the fixed rod 9 is rotatably connected to the filter plate 501. A collection box 11 for storing the screened chemical materials is provided at the bottom of the inner cavity of the box body 1. Slider 12 is fixedly connected to both sides of the bottom of the collection box 11. A sliding groove 13 is inserted into the bottom of the slider 12. The sliding groove 13 is opened on the inner wall of the box body 1.First, start the drive motor 502. The output shaft of the drive motor 502 drives the threaded rod 503 to rotate. During the rotation of the threaded rod 503, the drive threaded block 504 moves axially, thereby driving the adjusting plate 505 to move synchronously. As the adjusting plate 505 moves, the sliding of the limiting block 506 in the limiting groove 507 achieves stable guidance, ensuring precise translation on the surface of the filter plate 501. This, in turn, drives the adjusting plate 505 to translate on the surface of the filter plate 501. The adjusting plate 505 and the screen holes of the filter plate 501 form an adjustable coverage. By changing the position of the adjusting plate 505, the effective hole spacing of the screen holes can be precisely controlled to adapt to the screening requirements of different materials. After adjustment, open the sealing cover 4 through the hinge and pour the material into the surface of the filter plate 501 from the feed port 3. At this time, start the rotating motor 6. The shaft drives the rotating rod 7 to rotate, which in turn drives the elliptical disk 8 to rotate. The rotation of the elliptical disk 8 then drives the fixed rod 9 to rotate. During the rotation of the fixed rod 9, the filter plate 501 reciprocates up and down. Simultaneously, the sliding sleeve 508 slides against the surface of the sliding rod 509, and the elasticity of the spring 510 buffers the reciprocating motion of the filter plate 501, achieving stable vibration screening. During vibration, qualified material falls through the sieve holes 511 into the collection box 11 below for collection, completing the screening process. After screening, the collection box 11 can be easily pulled out by sliding the slider 12 within the chute 13, facilitating subsequent material processing. This allows for flexible adjustment of the sieve hole size according to actual needs, achieving adjustable screening of material particles.

[0028] A limiting ring 10 is inserted into one side of the rotating motor 6, and one side of the limiting ring 10 is fixedly connected to the outer wall of the box 1. By setting the limiting ring 10, the rotating motor 6 can be limited to rotate when it is working, which improves the stability of the rotating motor 6 during operation and avoids subsequent displacement, thus affecting the screening progress.

[0029] Working principle: First, start the drive motor 502. The output shaft of the drive motor 502 drives the threaded rod 503 to rotate. During the rotation of the threaded rod 503, the drive threaded block 504 moves axially, thereby driving the adjusting plate 505 to move synchronously. As the adjusting plate 505 moves, the sliding of the limiting block 506 in the limiting groove 507 achieves stable guidance, ensuring precise translation on the surface of the filter plate 501. This, in turn, drives the adjusting plate 505 to move on the surface of the filter plate 501. The adjusting plate 505 and the screen holes of the filter plate 501 form an adjustable coverage. By changing the position of the adjusting plate 505, the effective hole spacing of the screen holes can be precisely controlled to adapt to the screening requirements of different materials. After adjustment, open the sealing cover 4 through the hinge and pour the material into the surface of the filter plate 501 from the feed port 3. At this time, start the rotating motor 6. The output shaft drives the rotating rod 7 to rotate, which in turn drives the elliptical disk 8 to rotate. The rotation of the elliptical disk 8 then drives the fixed rod 9 to rotate. During the rotation of the fixed rod 9, the filter plate 501 is driven to reciprocate up and down. At the same time as the filter plate 501 reciprocates, the sliding sleeve 508 slides on the surface of the sliding rod 509, and the elasticity of the spring 510 makes the filter plate 501 reciprocate and buffer, so that the filter plate 501 achieves stable vibration screening. During the vibration, qualified materials fall into the collection box 11 below through the screen hole 511 and are collected, thus completing the screening process. After screening, the collection box 11 can be easily pulled out by sliding the slider 12 in the slide groove 13, which is convenient for subsequent material processing. Thus, the screen hole size can be flexibly adjusted according to actual needs to achieve the effect of adjusting the screening of material particles.
