Description

Technical Field

[0001] This utility model relates to the field of sealing agent pulverization technology, and in particular to a pulverization device for preparing sealing agents. Background Technology

[0002] Sealing agents are typically composed of multiple chemical components. During the preparation process, these components need to be fully mixed and react. After the material is pulverized, its particle size becomes smaller and its specific surface area increases significantly. For example, in some resin-based sealing agents, the filler is pulverized even finer, which can significantly increase its contact area with the resin matrix. As a result, in the subsequent mixing and curing reaction, the interaction between the filler and the resin is more complete, the reaction proceeds more thoroughly, and the performance of the sealing agent is improved.

[0003] Currently, when preparing sealing agents, pulverizing equipment such as air jet mills, vibratory mills, and impact mills are commonly used. Among them, air jet mills extract the pulverized material from the bottom of the device through a vacuum tube, and utilize the interaction between the airflow and the filter screen to transport the material to a collection device that has reached the appropriate particle size, thus playing a role in classification and collection.

[0004] Considering that materials of different particle sizes are used in the preparation of sealing agents to produce sealing agents with different compositions, existing pulverizing devices require replacing the filter screen to change the size of the collected material particles, thereby changing the size of the particles extracted by the vacuum tube. However, this replacement usually requires stopping the machine, disassembling the relevant parts of the pulverizer, removing the old filter screen, installing the new filter screen, and then reassembling and debugging. This process involves multiple steps, requires a high level of technical expertise, and consumes a lot of time each time, affecting production efficiency. Therefore, a pulverizing device for preparing sealing agents is proposed to solve the above problems. Utility Model Content

[0036] Reference Figure 1 , Figures 3-4This utility model provides an embodiment of a pulverizing device for preparing a sealing agent, comprising a pulverizing chamber 1, a filter chamber 5 fixedly connected to the top of the inner surface of the pulverizing chamber 1, providing fixed support for the filter chamber 5 via the top of the inner surface of the pulverizing chamber 1, a filter ring A11 slidably connected to the inner surface of the filter chamber 5, allowing the filter ring A11 to move vertically along the inner surface of the filter chamber 5, a rack A12 fixedly connected to the inner surface of the filter ring A11, allowing the rack A12 to engage with a subsequent gear 14, so that when the filter ring A11 moves vertically, the rack A12 can drive the gear 14 to rotate, and a vacuum tube 6 fixedly connected to the inner surface of the filter chamber 5, the vacuum tube 6 being used to generate negative pressure. The vacuum tube 6 is pressurized to draw in and collect the pulverized sealing agent particles in the pulverizing chamber 1, thus completing the collection of the pulverized product. A partition ring 20 is fixedly connected to the outer surface of the vacuum tube 6. The partition ring 20 serves as a structural support and component connection, providing an installation base for components such as the filter ring B9 and the oil drip head 13. It can also achieve a sealing effect when the two sets of filter rings are in the designated positions. A gear 14 is rotatably connected to the bottom of the inner surface of the partition ring 20, allowing the gear 14 to rotate along the bottom of the inner surface of the partition ring 20.

One end of the spring 16 is fixedly connected to the inner surface of the oil drip head 13, and the other end of the spring 16 is fixedly connected to the top of the outer surface of the ball valve 17, ensuring that the ball valve 17 can block the oil outlet in time when it is not squeezed.

[0040] Reference Figure 3 , Figure 6 , Figure 8 A movable part 10 is fixedly connected to the top of the outer surface of the filter ring A11, so that when the movable part 10 moves vertically, it can drive the filter ring A11 to move together. A handle is hinged to the inner surface of the movable part 10, so that the handle can provide a force point for the operator, making the operation simpler and more convenient. The outer surface of the movable part 10 is slidably connected to the inner surface of the filter chamber 5, so that the movable part 10 can always move vertically along the specified position under the restriction of the inner surface of the filter chamber 5. A bolt 19 is threadedly connected to the top of the inner surface of the filter chamber 5, so that the bolt 19 can fix the position of the movable part 10, so that when the movable part 10 is fixed, it can drive the filter ring A11 to be kept in the specified position.

[0041] Reference Figure 2 , Figure 5 , Figure 9The top of the outer surface of the crushing chamber 1 is fixedly connected to the feed pipe 3, which allows the feed pipe 3 to transport the sealing agent raw material to be crushed into the crushing chamber 1, ensuring a continuous supply of raw materials for the crushing operation. The bottom of the outer surface of the crushing chamber 1 is fixedly connected to the waste pipe 4, which is used to discharge impurities that cannot be crushed or sealing agents that have not met the crushing requirements after the crushing operation is completed, thus cleaning the inside of the crushing chamber 1. The top of the outer surface of the oil dripping head 13 is connected to a hose 15, which is used to connect to an external lubricating oil source to replenish the oil dripping head 13 with lubricating oil, ensuring that the oil dripping head 13 can continuously provide lubrication for the gear 14. The top of the outer surface of the hose 15 penetrates and is fixedly connected to the top of the inner surface of the partition ring 20, ensuring a stable connection between the hose 15 and the partition ring 20, and ensuring that the lubricating oil can smoothly enter the oil dripping head 13 through the hose 15. The top of the inner surface of the hose 15 is connected to an oil plug, which is used to seal the top opening of the hose 15 to prevent the lubricating oil from leaking when not in use.

[0042] Working principle: When crushing the sealant, motor 2 is started to drive the crushing wheel 7 to rotate. The sealant is then fed into the crushing chamber 1 through the feed pipe 3. Under the action of the crushing wheel 7 and the crushing ring 8, the sealant is crushed into relatively fine particles. Then, the vacuum tube 6 is activated to draw in and collect the finely crushed sealant particles. During the collection process, the particles are filtered by the filter ring inside the filter chamber 5. Only sealant particles that reach the specified particle size are drawn in and collected by the vacuum tube 6, while larger particles fall onto the crushing wheel 7 and continue to be crushed until the specified particle size is reached. After crushing, the waste pipe 4 is opened to discharge any uncrushed sealant particles from the crushing chamber 1.

[0043] When it is necessary to change the size of the particles sucked in by the vacuum tube 6, first unscrew the bolt 19, then press down the handle on the moving part 10 to make it move the filter ring A11 downward. When the filter ring A11 moves downward, the rack A12 on the filter ring A11 will mesh with the gear 14, and the gear 14 will rotate simultaneously. When the gear 14 rotates, it will mesh with the rack B18 on the other side, and the filter ring B9 will move upward. This allows the operation of one set of filter rings to simultaneously drive the other set of filter rings to move in the opposite direction, thereby changing the size of the particles sucked in by the vacuum tube 6.

[0044] Furthermore, an oil drip head 13 is provided on the gear 14, so that when the gear 14 rotates, the lubricating oil inside the oil drip head 13 can drip onto the gear 14 due to the compression of the ball valve 17 inside the oil drip head 13, thereby lubricating the gear 14.

[0045] 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.
