Description

Technical Field

[0001] This utility model relates to the technical field of sand mills for dispersing coatings, and particularly to a sand mill for dispersing coatings. Background Technology

[0002] The sand mill uses a pump to feed a solid-liquid mixture that has been pre-dispersed and wetted by a mixer into the cylinder. The material and the grinding media in the cylinder are stirred together by a high-speed rotating disperser, which causes strong collisions, friction and shearing between the solid particles in the material and the grinding media, thereby accelerating the grinding of particles and dispersing aggregates. The ground and dispersed material is separated from the grinding media by a dynamic separator and flows out from the discharge pipe.

[0003] The applicant discovered through a search that a Chinese patent, "A Sand Mill for Dispersing Conductive Coatings," with publication (announcement) number "CN212549820U," discloses a sand mill that disperses materials by rotating a dispersing disc via a transmission rod. The patent has five dispersing discs, allowing for more comprehensive material processing to meet basic sand milling requirements. However, this sand mill relies solely on a screen to separate materials from grinding beads, failing to ensure sufficient contact between the coating, grinding media, and filter components. This can lead to low separation efficiency and issues such as material residue and screen clogging. Furthermore, the document lacks a design for easy installation, disassembly, and cleaning of the filter components, resulting in relatively high maintenance difficulty. Therefore, we propose a sand mill for dispersing coatings. Utility Model Content

[0022] 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.

[0023] Example 1:

[0024] Please see the appendix Figure 1 - Appendix Figure 6A sand mill for dispersing coatings includes a frame 1 and a separation auxiliary mechanism 4 disposed below it. A collection mechanism 5 is disposed below the separation auxiliary mechanism 4. The separation auxiliary mechanism 4 includes a base 401, a separation cylinder 403, and a rotary motor 406. Sliding blocks 404 are fixedly installed on both sides of the separation cylinder 403. A toothed groove 405 is formed on the outer wall of one side of the sliding block 404. A filter plate 409 is snapped into the inside of the separation cylinder 403. An installation component 411 is installed on the separation cylinder 403 through an installation groove 410. The installation component 411 is connected to a limit plate 413 through a spring 412. The rotary motor 406 is connected to a protruding tooth 408 through a gear disk 407. A stirring motor 3 is fixedly installed at the upper end of the frame 1. A grinding chamber 2 is fixedly installed inside the frame 1. The grinding components inside the grinding chamber 2 are fixedly connected to the output end of the stirring motor 3. The upper end of the base 401 is close to the two sides. Support frames 402 are fixedly installed at the side positions. Sliding blocks 404 are slidably connected inside the support frames 402. The upper end of the separating cylinder 403 is slidably connected inside the grinding chamber 2. A limiting ring 414 is fixedly installed on the outer wall of the separating cylinder 403 near the upper end. The mounting groove 410 is opened on the upper surface of the separating cylinder 403 near both sides. The mounting piece 411 is fixedly installed inside the mounting groove 410. One end of the spring 412 is fixedly installed inside the mounting piece 411. The limiting plate 413 is fixedly installed on the other end of the spring 412 and is slidably connected inside the mounting piece 411. The bottom of the rotating motor 406 is fixedly installed on the upper end of the base 401. The gear disk 407 is fixedly installed on the output end of the rotating motor 406. The protruding tooth 408 is fixedly installed on the outer wall of the gear disk 407 and meshes with the tooth groove 405.

[0025] The grinding chamber 2 is existing technology, with a grinding structure inside that can grind and break down materials. The protruding teeth 408 and the tooth groove 405 engage intermittently. When engaged, the separating cylinder 403 slides upward along the inside of the grinding chamber 2. At the disengagement point, the limiting ring 414 abuts against the bottom of the frame 1. Then, the separating cylinder 403 slides downward along the inside of the grinding chamber 2. When it slides to the bottom, the sliding block 404 abuts against the bottom of the sliding groove of the support frame 402. At this time, the upper end of the separating cylinder 403 is still inside the grinding chamber 2, ensuring that the internal materials do not leak out.

[0026] Specifically, the combination of sliding block 404, toothed groove 405, rotating motor 406, gear disk 407, and protruding tooth 408 enables the separating cylinder 403 to slide stably. This not only allows the coating and grinding media to fully contact the filter plate 409, improving separation efficiency, but also effectively prevents the filter plate 409 from clogging. Furthermore, the separating cylinder 403 is connected to the limiting plate 413 through the mounting groove 410, mounting part 411, and spring 412, facilitating the installation, disassembly, and cleaning of the filter plate 409, making maintenance convenient. The overall stability of the equipment is also ensured by the sliding connection between the sliding block 404 and the support frame 402, the sliding connection between the separating cylinder 403 and the grinding chamber 2, and the setting of the limiting ring 414, providing a reliable and efficient solution for coating dispersion operations.

[0027] Example 2:

[0028] Please see the appendix Figure 1 and attached Figure 7 Furthermore, based on Embodiment 1, the collecting mechanism 5 includes a receiving box 501, which is fixedly installed on the upper end of the base 401. A receiving drawer 502 is slidably connected inside the receiving box 501. A threaded groove 503 is provided on the upper inner wall of the receiving box 501. A threaded component 504 is threadedly connected inside the threaded groove 503. A sealing bag 505 is fixedly installed on the upper end of the threaded component 504. The upper end of the sealing bag 505 is fixedly installed on the lower end of the separating cylinder 403.

[0029] The sealing bag 505 ensures that the separating cylinder 403 can slide up and down without restriction, while preventing material leakage, and the threaded connection facilitates separation.

[0030] Specifically, the collection box 501, in conjunction with the collection drawer 502, facilitates the centralized collection of separated paint. The drawer design also makes it easy to clean and remove the collected paint. The sealing bag 505 is connected to the threaded groove 503 of the collection box 501 via a threaded part 504, achieving a sealed connection between the separating cylinder 403 and the collection box 501. This not only effectively prevents paint leakage during the transfer process, avoiding paint waste and pollution of the working environment, but also ensures that the quality of the collected paint is not affected by external factors, thus improving the integrity and purity of the collected paint.

[0031] Working principle of this utility model: This utility model is a sand mill for dispersing coatings. Material is added to the grinding chamber 2, and the stirring motor 3 and the rotating motor 406 are turned on. Their output drives the grinding media inside the grinding chamber 2 to rotate, grinding and dispersing the coating, refining the particles in the coating to achieve the required fineness and dispersion effect. The ground coating enters the separation cylinder 403. The output of the rotating motor 406 drives the gear disk 407 to rotate. Because the protruding teeth 408 fixed on the outer wall of the gear disk 407 mesh with the tooth grooves 405 on the outer wall of the sliding block 404, the rotation of the gear disk 407 causes the sliding block 404 to slide within the support frame 402, thereby causing the separation cylinder 403 to slide up and down along the sliding connection with the grinding chamber 2. A filter plate 409 is engaged inside the separation cylinder 403. During the sliding process of the separation cylinder 403, the mixture of coating and grinding media... The coating material continuously tumbles and moves on the filter plate 409, allowing the coating to pass through while the grinding media is intercepted by the filter plate 409, thus separating the coating and the grinding media. At the same time, the limiting ring 414 on the separation cylinder 403 restricts the sliding range of the separation cylinder 403, ensuring the stability of the separation process. The combination structure of the mounting groove 410, mounting part 411, spring 412 and limiting plate 413 can be used to fix the filter plate 409. The elasticity of the spring 412 can make the limiting plate 413 fit tightly against the filter plate 409, ensuring that the filter plate 409 will not loosen during the separation process. After separation, the coating material flows into the collection box 501 of the collection mechanism 5 through the sealed cloth bag 505 at the lower end of the separation cylinder 403. The collection drawer 502 in the collection box 501 is used to collect the coating material. When it is necessary to take out the collected coating material, the collection drawer 502 can be directly pulled out from the collection box 501 to complete the coating material collection operation.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
