Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire-retardant coating production technology, specifically a grinding device for fire-retardant coating production. Background Technology
[0002] Fire-retardant coatings are an indispensable functional coating in building materials. Their main function is to improve the fire resistance of buildings, slow down the spread of fire, and protect building structures and internal facilities from high-temperature damage. The performance and quality of fire-retardant coatings largely depend on the selection of raw materials and processing technology. Among them, the grinding of raw materials is a key link. The performance of grinding equipment directly affects the particle size, uniformity, and activity of the raw materials for fire-retardant coatings, and thus affects the performance and quality of the final product.
[0003] Existing grinding devices for fire-retardant coating production mostly use grinding cylinders to grind block coatings. In the actual grinding process, the grinding speed of block fire-retardant coatings varies, resulting in granular coatings of varying sizes. The finer granules fill the gaps between the larger granules and act as a lubricant, reducing the friction between the granules and thus lowering the grinding efficiency of the coating. In view of this, a grinding device for fire-retardant coating production is proposed. Utility Model Content

[0029] Please see Figure 1-4 This utility model provides a new technical solution: a grinding device for producing fireproof coatings, including a grinding box 1, with a feed hopper 2 fixedly installed on the upper surface of the grinding box 1;
[0030] The grinding box 1 is equipped with a grinding mechanism, which includes an L-shaped fixed block 3, a first motor 4, a first pulley 5, a belt 6, a second pulley 7, a lead screw 8, a flow gravity head 9, a crushing bucket 10, a screening plate 11, a first vibrating motor 12, a waste box 13, a grinding bucket 14, a fixed roller 15, a spring 16, a second vibrating motor 17, a second motor 18, and a grinding block 19.

[0034] Furthermore, the lead screw 8 is fixedly sleeved on the inner surface of the second pulley 7, and the upper end of the lead screw 8 is rotatably connected to the inner wall of the horizontal plate of the L-shaped fixing block 3.
[0035] Among them, the flow gravity head 9 is threaded onto the outer surface of the lead screw 8, and the upright of the flow gravity head 9 is slidably sleeved in the inner wall of the vertical plate of the L-shaped fixing block 3.
[0036] Furthermore, the crushing bucket 10 is fixedly installed in the inner wall of the top plate of the L-shaped fixed block 3, the screening plate 11 is set in the inner wall of the grinding box 1, and the first vibration motor 12 is fixedly installed on the lower surface of the screening plate 11.
[0037] The waste box 13 is fixedly installed on the inner surface of the bottom plate of the grinding box 1.
[0038] Furthermore, the grinding bucket 14 is fixedly installed on the inner surface of the bottom plate of the grinding box 1, two second vibration motors 17 are fixedly installed on the lower surface of the two horizontal plates of the grinding bucket 14 respectively, and two fixed rollers 15 are respectively slidably sleeved in the inner wall of the two horizontal plates of the grinding bucket 14. The two fixed rollers 15 are fixedly installed in the inner wall of the grinding box 1.
[0039] Two springs 16 are fixedly installed on the lower surfaces of the two horizontal plates of the grinding bucket 14.
[0040] Furthermore, the second motor 18 is fixedly installed on the lower surface of the top plate of the grinding box 1, and the grinding block 19 is fixedly installed on the output end of the second motor 18;
[0041] When using the grinding device for fire-retardant coating production, the fire-retardant coating is added to the grinding chamber 1 through the feed hopper 2. The coating is then heated. Simultaneously, the first motor 4 is started, driving the first pulley 5, which is fixedly mounted on the outer surface of the output shaft, to rotate. The first pulley 5 drives the belt 6, which is connected to the outer surface, to rotate. The belt 6 drives the second pulley 7, which is connected to the inner surface, to rotate. The second pulley 7 drives the lead screw 8, which is fixedly mounted on the inner surface, to rotate.

The flow gravity head 9 then... The gap between the feed hoppers 2 is widened, allowing fire retardant coating to be added to the crushing hopper 10.

[0042] This grinding device for fire-retardant coating production uses a crushing hopper 10 to initially crush the raw materials, breaking larger particles into uniformly sized particles. Smaller particles that meet the particle size requirements are then passed through a screening plate 11 and fed into a grinding hopper 14 for further grinding, resulting in uniform particle size and facilitating subsequent grinding. The device also uses a flow gravity head 9 to control the feeding speed of the raw materials in the feed hopper 2, ensuring that the raw materials enter the crushing hopper 10 evenly and stably, preventing excessive accumulation of raw materials on the surface of the screening plate 11, which could reduce the screening effect.
[0043] Structural Description:

[0059] Spring 16: During the grinding process, it reduces the impact of the vibration of the grinding bucket 14 on the entire device, and at the same time, it enables the grinding bucket 14 to adapt to different grinding pressures to a certain extent.
[0060] Second motor 18: The second motor 18 provides power for the rotation of the grinding block 19, so that the grinding block 19 rotates at high speed in the grinding bucket 14 to grind the raw materials.
[0061] Grinding block 19: Rotates at high speed driven by the second motor 18, cooperating with the fixed roller 15 to grind the raw material to the required fineness.
