[0035] See appendix Figures 1-7 As shown in the figure, an embodiment of the present invention provides a device for precise control of calcium hydroxide particle size, including a workbench 1 and a particle size control component 5 for precise control of calcium hydroxide particle size. One end of the upper surface of the workbench 1 is provided with a collection hole 104, and a fixed cylinder 3 is fixedly installed at one end of the upper surface edge of the collection hole 104. The particle size control component 5 is detached and installed on one side of the fixed cylinder 3. An installation rod 2 is fixedly installed at the other end of the upper surface of the workbench 1. A slot is provided on one side of the workbench 1, and a vibration motor 302 is provided in the slot. A linkage cylinder 301 is fixedly installed at one end of the outer surface of the fixed cylinder 3.

[0036] One end of the mounting rod 2 is fixedly connected to the feed hopper 201. Two sets of material distribution inclined plates 202 in opposite positions are installed on the inner wall of the feed hopper 201. The feed hopper 201 is located at the upper end of the fixed cylinder 3 and the particle size control component 5.

[0037] One end of the output shaft of the vibration motor 302 is connected to a transmission roller 303, which passes through the slot of the worktable 1 and extends into the linkage cylinder 301.

[0038] The upper surface of the workbench 1 is provided with two sets of upper sliding grooves 103, and an upper slider 107 is slidably installed in the upper sliding grooves 103. The upper slider 107 is fixedly installed at one end of the lower surface of the particle size control component 5. One end of the lower surface of the workbench 1 is provided with a lower sliding groove 102, and a lower slider 106 is slidably installed in the lower sliding groove 102. One end of the lower surface of the lower slider 106 is fixedly connected to a collection box 101, and a limit ring 105 is fixedly installed at one end of the lower surface of the collection hole 104. T-shaped blocks 403 are fixedly installed on both sides of the particle size control component 5, and positioning frames 404 are provided on both sides of the fixed cylinder 3. The upper surface of the T-shaped blocks 403 and the positioning frames 404 and the T-shaped blocks 403 are provided with the same through holes, and positioning rods 405 are inserted into the through holes.

[0039] The two sets of oppositely positioned distribution inclined plates 202 installed on the inner wall of the feed hopper 201 of the above technical solution can evenly disperse the particles in the guide fixing cylinder 3 and the particle size control component 5 when the particles are poured in, thereby improving the control efficiency and facilitating the use of a precise particle size control device for calcium hydroxide particles.

[0040] When the particles enter the particle size control component 5, the vibration motor 302 is started and the vibration is transmitted to the particle size control component 5 at one end of the fixed cylinder 3 through the transmission roller 303 connected to the output shaft. This allows the particles to be screened sequentially in the particle size control component 5 so that the particle size meets the appropriate requirements. After that, the screened particles fall from the particle size control component 5 into the collection box 101 of the lower collection hole 104, which improves the particle size control and collection efficiency. The particle size control component 5 is equipped with an upper slider 107 on its lower surface to facilitate its sliding in the upper groove 103, which improves the disassembly efficiency. The collection box 101 is equipped with a lower slider 106 on its upper surface to facilitate the removal and installation of the collection box 101. The limiting ring 105 ensures that the collection box 101 and the collection hole 104 are aligned when the collection box 101 is installed, which can effectively improve the uniformity of particle size screening and prevent the occurrence of mixed particles with different sizes.

[0041] When the particle size control component 5 and the fixed cylinder 3 are attached, and the T-shaped block 403 is inserted into the positioning frame 404, the positioning rod 405 is inserted into the through hole for fixing, which can ensure the stability and accuracy of the connection between the particle size control component 5 and the fixed cylinder 3, and facilitate disassembly and assembly.

[0042] To further improve the ability to control the particle size, the particle size control component 5 can effectively control the size of the particles, ensuring that the sieved particles are uniform and consistent, and preventing the mixing of particles with large size ranges.

[0043] See appendix Figure 5 To be continued Figure 7As shown, the particle size control component 5 includes a first movable cylinder 501, which is slidably mounted on one end of the upper surface of the upper sliding groove 103. An upper sliding block 107 is fixedly mounted on one end of the lower surface of the first movable cylinder 501. T-shaped blocks 403 are fixedly mounted on both sides of the first movable cylinder 501. A second movable cylinder 502 is detachably mounted on one end of the upper surface of the first movable cylinder 501. Multiple sets of identical frame slots 304 are provided on one end of the inner walls of the first movable cylinder 501, the second movable cylinder 502, and the fixed cylinder 3. Filter frames 504 are detachably mounted in each of the multiple sets of frame slots 304. Each filter frame 504 located in the first movable cylinder 501 and the second movable cylinder 502 has an identical threaded hole at one end. A bolt 503 is threaded into the threaded hole and inserted through the second movable cylinder 502 into the first movable cylinder 501. Multiple filter frames 504 are each equipped with filter screens of different pore sizes, with pore sizes of 100μm, 50μm, 25μm, and 10μm from top to bottom. A connecting ring 4 is fixedly installed on one side of both the first movable cylinder 501 and the second movable cylinder 502. A connecting bolt 401 is inserted between the two sets of connecting rings 4. A handle 402 is installed on the connecting ring 4 located on the second movable cylinder 502.

[0044] To improve the precision of particle size control for calcium hydroxide particles, a filter frame 504 installed in the slot 304 within the first and second movable cylinders 501 and 502 can be used to precisely control the particle size through sieving. The filter screens installed in the filter frame 504 have apertures of 100μm, 50μm, 25μm, and 10μm, respectively. By gradually reducing the aperture of the filter screen, particles in different size ranges can be effectively removed, resulting in a narrower particle size distribution that better meets the requirements for precise particle size control. This effectively avoids the problems of uneven particle size distribution and difficulty in precise control.

[0045] In use, by pulling out the positioning rod 405, the particle size control component 5 and the fixed cylinder 3 are separated. Then, the pull handle 402 at one end of the second movable cylinder 502 is pulled, causing it to move out through the upper slider 107. During the movement, the filter frame 504 is pulled out from the frame slot 304 in the fixed cylinder 3. Then, the insertion bolt 503 at one end of the filter frame 504 inserted in the first movable cylinder 501 and the second movable cylinder 502 is turned, so that the installed filter frames 504 are released from bottom to top. Then, the required filter screen aperture is selected according to the needs, and the unnecessary filter frames 504 are removed from the first movable cylinder 501 and the second movable cylinder 502. This can meet different particle size requirements, improve its control efficiency, flexibly realize the precise screening and control of calcium hydroxide particles of different particle sizes, improve the overall control efficiency, and the first movable cylinder 501 and the second movable cylinder 502 can be disassembled and assembled, improving the convenience of maintenance.

[0046] The working principle of this utility model embodiment is as follows: Two sets of oppositely positioned distributing inclined plates 202 installed on the inner wall of the feed hopper 201 can evenly disperse the microparticles into the guide fixing cylinder 3 and particle size control component 5 during feeding. The microparticles then enter the filter frames 504 within the particle size control component 5. The vibration motor 302 is then activated, transmitting vibration through the transmission roller 303 connected to the output shaft to one end of the fixing cylinder 3 connected to the particle size control component 5. This allows the microparticles to be sequentially sieved in multiple sets of filter frames 504. The filter mesh apertures installed in the filter frames 504 are 100μm, 50μm, 25μm, and 10μm respectively. By gradually reducing the filter screen aperture, particles of different size ranges can be effectively removed, resulting in a narrower particle size distribution that better meets the requirements for precise particle size control. Then, particles of the appropriate size fall into the collection box 101 through the lower collection hole 104. After that, the fixing bolt 503 at one end of the filter frame 504 inserted into the first movable cylinder 501 and the second movable cylinder 502 is turned to release the restrictions on the installed filter frame 504 from bottom to top. Then, the required filter screen aperture is selected according to the needs, and the unnecessary filter frame 504 is removed from the first movable cylinder 501 and the second movable cylinder 502.

[0047] In summary, the overall structure of this utility model embodiment has a high degree of control over calcium hydroxide particles, enabling precise control and avoiding mixing due to large particle size ranges. The particle size distribution is uniform, which can effectively meet the application scenarios with high requirements for particle size uniformity.
