Abstract
Description
Technical Field
[0001] This utility model relates to the field of sieving equipment technology, specifically a sieving device for solid granules. Background Technology
[0002] As a key piece of equipment for material classification and processing, screening equipment occupies an important position in many fields such as chemical, food, pharmaceutical, and mining. Its core function is to separate mixed materials according to particle size through screens of different specifications, thereby meeting the requirements of subsequent production processing or product quality.
[0003] Chinese Patent Announcement No. CN222385228U discloses a pharmaceutical solid granule sieving device, comprising: a shell, a feeding hopper fixedly installed on the top of the shell, an outlet connected to the inlet of the shell at the bottom of the inner cavity of the feeding hopper, a chute inside the feeding hopper and on one side of the outlet, a baffle slidably installed in the chute, multiple screening rods and an inclined plate fixedly installed from top to bottom inside the shell and directly below the outlet, and a fixing plate fixedly installed at the bottom of the tail end of the multiple screening rods inside the shell. In this invention, the overall device ensures control over the feeding speed during use, avoiding the addition of too much solid granule at once which would affect the sieving effect. Furthermore, the overall device can sieve solid granules of three sizes, resulting in better sieving and more uniform particle size for each size.
[0004] In the existing technology, in the use of a pharmaceutical solid granule sieving equipment, the equipment uses a fixed sieving rod and an inclined plate for sieving. The sieving process and specifications are fixed, and it is impossible to change the sieving aperture according to the particle size requirements of different granules. When it is necessary to process granules with different particle size ranges, the entire sieving set must be replaced, which is complicated and time-consuming, and seriously limits the application scenarios of the equipment. Therefore, we have made improvements to this and proposed a solid granule sieving equipment. Utility Model Content

A worm 12 is meshed on the outside of the multiple worm wheels 11. The worm 12 is fixedly connected to the second fixed rod 10. The multiple worm wheels 11 and worm 12 are rotatably connected to the screen plates 3.
[0038] Multiple auxiliary rods 15 are fixedly mounted with sleeve rods 17 on their outer sides. Multiple screen plates 3 are fixedly mounted with two guide rods 14 inside each screen plate 3. The guide rods 14 pass through the slide plate 6 and are slidably connected to it. Multiple screen plates 3 are provided with an arc plate 20, a connecting plate 23 and two limiting plates 21 on their tops. Adjacent arc plates 20, connecting plates 23 and two limiting plates 21 are fixedly connected. Multiple arc plates 20, connecting plates 23 and two limiting plates 21 are slidably connected to the screening box 1. Two magnets are embedded on the side of the arc plate 20 and the screen plate 3 that are close to each other. The corresponding two magnets are magnetically connected. The sleeve rods 17 provided on multiple screen plates 3 have different diameters, and the diameter of the sleeve rods 17 increases from top to bottom.
[0039] Multiple auxiliary rods 15 are fixedly installed on the outer side and on the corresponding sides of the sleeve rod 17. The first auxiliary plate 18 and the second auxiliary plate 19 are slidably connected to each other. The first auxiliary plate 18 and the second auxiliary plate 19 are both inserted into the inside of the sieve plate 3 and slidably connected to it.
[0040] A second servo motor is fixedly installed inside the feeding box 2. A stirring shaft is fixedly installed at the output end of the second servo motor.

The multiple fixing bolts 25 are inserted into the interior of the screening box 1 and are threadedly connected thereto.
[0043] A controller 26 is embedded on one side of the screening box 1. The controller 26 is electrically connected to the first servo motor 13. Guide plates 22 are fixedly installed on the inner walls of both sides of the screening box 1.
[0044] In this embodiment of the utility model, the design of the multi-layer sieve plate 3 and the sleeve rods 17 of different diameters enables multi-stage precise sieving of particles, meets the grading requirements of particles of different sizes, significantly improves product quality, and achieves the purpose of efficient and precise sieving.
[0045] After the solid granules are placed into the feeding box 2, the second servo motor starts, driving the stirring shaft and spiral blades to rotate. The spiral blades continuously stir the granules and push them to the feeding trough. The feeding trough evenly conveys the granules to the sieve plate 3 at the top of the screening box 1. The rotation of the stirring shaft and spiral blades realizes the stirring and conveying of the granules, so that the granules are evenly mixed and conveyed stably before entering the screening box 1, avoiding the impact of particle accumulation or uneven distribution on the subsequent screening effect.
[0046] When the screen plate 3 needs cleaning or replacement, open the box door 24 and fix the box door 24 with fixing bolts 25. The controller 26 controls the first electric telescopic rod and the second electric telescopic rod to work together to pull the U-shaped block out of the screen plate 3, release the fixing of the screen plate 3, and then pull the screen plate 3 out along the rotating rod 4 for cleaning or replacement. The arc plate 20 is magnetically connected to the screen plate 3 by a magnet, so that it can block the material conveying. The cleaning and replacement of the screen plate 3 is achieved through the box door 24, the auxiliary structure and the magnetically connected arc plate 20. The whole process does not require complicated tools and cumbersome steps, which further reduces the equipment downtime, avoids production interruption caused by the blockage or damage of the screen plate 3, ensures production continuity, and also facilitates the thorough cleaning and timely replacement of the screen plate 3, extending the service life of the equipment and reducing maintenance costs.
[0047] A transparent window is provided on the door 24, allowing operators to directly observe the screening process inside the screening box 1.
[0048] Example 3: Please refer to the appendix of the instruction manual. Figure 2 Included with instruction manual Figure 5 In a preferred embodiment of this utility model, each of the multiple sieve plates 3 has an auxiliary structure at its bottom. The auxiliary structure includes a fixing block, which is fixedly connected to the screening box 1. A first electric telescopic rod is embedded in the top of the fixing block. A rotating plate is positioned above the first electric telescopic rod. A first auxiliary block and a second auxiliary block are rotatably connected to both sides of the rotating plate via rotating shafts. The output end of the first electric telescopic rod is fixedly connected to the first auxiliary block. An insert block is provided at the bottom of the sieve plate 3, and the insert block is inserted into the interior of the sieve plate 3 and slidably connected thereto. A second auxiliary block is inserted into the interior of the insert block and slidably connected thereto. A guide rod is fixedly installed, and the guide rod passes through the second auxiliary block and is slidably connected to it. A second electric telescopic rod is fixedly installed inside the insert block. A rack is fixedly installed at the output end of the second electric telescopic rod, and the rack is slidably connected to the insert block. A gear meshes with the outside of the rack, and the gear is rotatably connected to the insert block. A bidirectional lead screw is rotatably connected inside the insert block, and the bidirectional lead screw passes through the gear and is fixedly connected to it. Two U-shaped blocks are threadedly connected to the outside of the bidirectional lead screw. Both U-shaped blocks are inserted into the inside of the sieve plate 3 and are slidably connected to it. The controller 26 is electrically connected to the first electric telescopic rod and the second electric telescopic rod.
[0049] In this embodiment of the invention, when it is necessary to adjust the tilt angle of the sieve plate 3 to optimize the screening effect, the controller 26 controls the first electric telescopic rod to extend or shorten. The first electric telescopic rod pushes the first auxiliary block, which drives the second auxiliary block to move through the rotating plate. The second auxiliary block slides in the insert block and simultaneously drives the guide rod to move. The second electric telescopic rod is activated, and the rack at its output end drives the gear to rotate. The gear is fixedly connected to the bidirectional lead screw, causing the bidirectional lead screw to rotate, thereby driving the two U-shaped blocks to slide in the sieve plate 3, realizing the rotation of the sieve plate 3 around the rotating rod 4, and completing the adjustment of the tilt angle of the sieve plate 3.
[0050] The angle of the sieve plate 3 can be flexibly adjusted through the auxiliary structure. Operators can adjust the tilt angle of the sieve plate 3 according to the characteristics of different granules and specific screening requirements. The appropriate tilt angle can optimize the movement trajectory and residence time of the particles on the sieve plate 3, so that the screening effect can reach the best state, greatly improving the applicability of the equipment and meeting the needs of various production scenarios.
[0051] The controller 26 embedded on one side of the screening box 1 is electrically connected to components such as the first servo motor 13, the first electric telescopic rod, and the second electric telescopic rod. The controller 26 controls the operation of each component in a unified manner to realize the automated operation of the screening process.
