DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1: Figure 1 - Figure 4 As shown, the utility model provides a chemical raw material grinding device for chemical industry, comprising a fixed plate 2, a sleeve 1 is installed on one side of the fixed plate 2, and a shaking mechanism 6 is installed on the inner side of the sleeve 1;

[0025] The shaking mechanism 6 includes a sleeve 62 and a screen 61. The top and bottom ends of the sleeve 62 are rotatably connected to a movable block 64. A rotating rod 63 is installed on the inner side of the movable block 64. The outer surface of the rotating rod 63 is fixedly connected to a pushing block 631. Springs 65 are fixedly connected on both sides of the movable block 64. The sleeve 62 is observed at the bottom end of the rotating rod 63. A first connecting shaft 66 is fixedly connected to the bottom of the sleeve 62. The bottom of the first connecting shaft 66 is rotatably connected to a second connecting shaft 67. Limit rods 651 are installed on the inner sides of both ends of the spring 65, and one of the limit rods 651 is fixedly connected to the movable block 64.

[0026] The specific configuration and function of this embodiment are described in detail below. First, the chemical raw materials to be processed are poured into the crushing box 3. The crushing box 3 is the core component of the entire processing flow, and its design can ensure that the raw materials are fully ground inside. Next, the first drive motor 4 is started. It is connected to the grinding roller inside the crushing box 3 through a transmission device, and the grinding roller is driven to start rotating. The powerful force generated by the rotation of the grinding roller can efficiently crush the raw materials to achieve the desired particle size.

[0027] As the grinding roller rotates, the crushed material gradually falls into the screen 61. The screen 61 is a key part of the entire screening process. It is finely designed and has a moderate mesh size to ensure that only material particles that meet the requirements can pass through. At this point, the screening work officially begins.

[0028] At the same time, in order to further improve the screening efficiency, the rotating rod 63 starts to rotate. The rotation speed of the rotating rod 63 is carefully designed to match the screening process of the screen 61. During the rotation process, the rotating rod 63 will periodically hit the sleeve 62. This impact force causes the sleeve 62 to shake, thereby driving the movable block 64 connected thereto to slide inside the sliding groove 22.

[0029] During the sliding process, the movable block 64 will continuously hit the spring 65. The design of the spring 65 enables it to withstand such impact force and undergo elastic deformation during the impact process. When the spring 65 is squeezed, it accumulates energy; and when the impact force disappears, the spring 65 will quickly return to its original state and release the energy. This release of energy causes the movable block 64 to shake violently, thereby accelerating the screening process of the crushed chemical raw materials.

[0030] Through this design, the entire screening process is not only efficient but also stable. The shaking of the movable block 64 can effectively prevent the material from piling up on the screen 61, ensuring that the screen 61 always remains unobstructed. At the same time, the elastic deformation of the spring 65 can also alleviate the damage caused by the impact force to the equipment to a certain extent, thereby extending the service life of the equipment.

[0031] Embodiment 2: Figure 2 and Figure 3As shown, the sleeve 62 is located on the inner side of the screen 61, and the screen 61 is located on the inner side of the sleeve 1. Two support plates 21 are symmetrically fixedly connected to one side of the fixed plate 2, and a sliding groove 22 is provided on the inner side of the support plate 21, and another limit rod 651 is fixedly connected to the support plate 21. The bottom of the sleeve 1 is fixedly connected with a discharge port 11, and an inner tube 12 is provided inside the discharge port 11. A second drive motor 68 is installed at the bottom of the inner tube 12, and the output end of the second drive motor 68 is fixedly connected to the second connecting shaft 67. A crushing box 3 is installed on the top of the fixed plate 2, and a first drive motor 4 is installed on one side of the crushing box 3. A material guide port 5 is fixedly connected to the bottom of the crushing box 3, and the material guide port 5 is located above the screen 61.

[0032] The effect achieved by the entire embodiment is that the sleeve 62 plays a vital role in the fine screening process. As the screening operation proceeds, the sleeve 62 will accurately drive the top and bottom movable blocks 64 to coordinate according to the screening requirements. This activity not only ensures the smooth progress of the screening process, but also directly affects the position change of the rotating rod 63. In order to more accurately control the movement of the rotating rod 63, we introduce the second drive motor 68 as a key component.

[0033] The introduction of the second drive motor 68 enables us to drive the second connecting shaft 67 to move flexibly through its driving action. At the same time, the first connecting shaft 66 and the second connecting shaft 67 together form a structure similar to a universal shaft. Even if the position of the rotating rod 63 changes, the rotating rod 63 can still maintain a stable rotation state through the precise control of the second drive motor 68, thereby ensuring the continuity and efficiency of the screening process.

[0034] When the screening process is completed, the screened raw materials will be smoothly discharged through the pre-set discharge port 11 and enter the next process or storage device.

[0035] The use method and working principle of the device: When crushing chemical raw materials, first pour them into the crushing box 3. Then, the first drive motor 4 is started to drive the grinding roller inside the crushing box 3 to rotate. The ground materials will naturally fall into the screen 61, and the materials of different particle sizes will be separated through the screening effect of the screen 61.

[0036] During the screening process, the rotation of the rotating rod 63 will periodically hit the sleeve 62, causing the sleeve 62 to shake. This shaking will further drive the movable blocks 64 at the top and bottom ends to slide inside the sliding groove 22. During the sliding process, the movable block 64 will hit the spring 65 back and forth, causing the spring 65 to be squeezed and compressed and deformed, thereby increasing the shaking amplitude of the movable block 64. This strong shaking helps to speed up the screening speed and improve the screening efficiency.

[0037] When the movable block 64 moves under the drive of the sleeve 62, the position of the rotating rod 63 may be changed. However, at this time, the second connecting shaft 67 moves through the drive of the second driving motor 68, and cooperates with the first connecting shaft 66 to form a universal shaft-like effect, thereby ensuring that the rotating rod 63 can maintain stable rotation while changing its position.

[0038] Finally, after the screening is completed, the raw materials that meet the requirements will be smoothly discharged through the discharge port 11 for subsequent use or processing. The entire crushing and screening process ensures efficient processing and screening of chemical raw materials through the coordinated work of multiple components.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
