Description

Technical Field

[0001] The utility model relates to a pulverizing device, in particular to a raw material pulverizing device used for chemical material processing, belonging to the technical field of chemical industry. Background Art

[0002] Chemical engineering is the abbreviation of "chemical technology", "chemical industry" and "chemical engineering". Any technology that uses chemical methods to change the composition and structure of substances or synthesize new substances belongs to chemical production technology, that is, chemical technology, and the resulting products are called chemicals or chemical products. At first, such products were produced in workshops, which later evolved into factories and gradually formed a specific production industry, namely the chemical industry. Chemical engineering is a science that studies the common laws of the production process of chemical products.

[0003] In the process of chemical raw material processing, in order to improve the reaction efficiency and processing quality of the materials, increase the surface area of ​​the materials, thereby accelerating the speed of the chemical reaction and improving the uniformity of the reaction, the raw materials need to be crushed. Therefore, a crushing device is needed. The authorization announcement number (CN 216605422 U) discloses a raw material crushing device for chemical material processing, including a bottom plate, the top of the bottom plate is fixedly connected with two support plates, the tops of the two support plates are fixedly connected with a connecting plate, the top of the connecting plate is fixedly connected with a crushing bin, the top of the crushing bin is fixedly connected with a feed bin having one end penetrating and extending into the crushing bin, the inside of the crushing bin is provided with two crushing assemblies, and the inside of the crushing bin is provided with two adjustment mechanisms;

[0004] Although the above technology can control the material feeding and discharging rate by changing the distance between the two baffles through the setting of the adjustment mechanism, the opening and closing of the feeding hole and the discharging hole can be realized through the two baffles, thereby facilitating the adjustment of the rate at which the raw materials enter and leave the crushing bin, avoiding excessive feeding at one time and uneven crushing of the raw materials by the crushing assembly. However, the volume of the materials after crushing may vary. The above technology may not be convenient for fine screening of materials of different volumes, and the particle size of the final product cannot be effectively controlled, resulting in uneven particle size distribution, which will seriously affect the efficiency of subsequent chemical reactions and the quality of products. Secondly, the inability to effectively remove oversized particles may cause difficulties in handling downstream equipment and increase the risk of wear and blockage, thereby reducing the efficiency and stability of the entire production line.

[0005] Therefore, a raw material crushing device for chemical material processing is proposed. Utility Model Content

Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, the embodiment of the utility model provides a crushing box body 1, the top of the crushing box body 1 is connected to a feed pipe 2, the front side of the crushing box body 1 is movably connected to a box door 3, the inner cavity of the crushing box body 1 is provided with a screening mechanism 4, the screening mechanism 4 includes a bidirectional motor 401, a screen 402, a transmission rod 403, a through hole 404, a weight block 405 and a spring 406, the bidirectional motor 401 is arranged in the inner cavity of the crushing box body 1, the number of the bidirectional motors 401 is two, and they are symmetrically arranged on the front and rear sides of the inner cavity of the crushing box body 1, The screen 402 is fixedly installed on the inner side of the bidirectional motor 401, the transmission rod 403 is fixedly installed on the output end of the bidirectional motor 401, the eccentric weight block 405 is fixedly connected to the outer side of the transmission rod 403, the through hole 404 is opened on the left and right sides of the surface of the crushing box body 1, the transmission rod 403 passes through the through hole 404 and extends to the outer side of the crushing box body 1, the spring 406 is fixedly installed on the outer side of the bidirectional motor 401, the other end of the spring 406 is fixedly connected to the inner cavity of the crushing box body 1, and the transmission rod 403 is located on the inner side of the spring 406.

[0027] By setting up the screening mechanism 4, the screening efficiency can be significantly improved, the particles can be dispersed, the aggregation between particles can be reduced, and smaller particles can pass through the screen faster. At the same time, large-size particles can be filtered, the particle size distribution can be controlled, and the quality and consistency of the final product can be improved. In addition, the risk of clogging and wear can be reduced, and the service life of the screen and other related equipment can be extended, thereby reducing maintenance costs and downtime.

[0028] Example 2

[0029] In one embodiment, a servo motor 5 is fixedly installed on the front side of the surface of the crushing box body 1, and the output end of the servo motor 5 is fixedly connected to the main crushing roller 6. The inner cavity of the crushing box body 1 is movably connected to the auxiliary crushing roller 7, and the surface of the auxiliary crushing roller 7 is meshed with the surface of the main crushing roller 6. Protective covers 8 are fixedly installed on the left and right sides of the surface of the crushing box body 1, and the eccentric weight 405 is located on the inner side of the protective cover 8. A storage box 9 is provided at the bottom of the inner cavity of the crushing box body 1.

[0030] The main crushing roller 6 is driven to rotate by the servo motor 5, and the main crushing roller 6 drives the auxiliary crushing roller 7 to rotate inward due to the surface engagement, so as to crush the raw material. Through the setting of the protective cover 8, the eccentric weight block 405 can be protected during the rotation of the eccentric weight block 405 to prevent the operator from accidentally touching it during the rotation of the eccentric weight block 405, thereby causing personal injury accidents. Through the setting of the storage box 9, the crushed material can be stored.

[0031] When the utility model is working: after the raw materials are prevented from entering the inner cavity of the crushing box body 1 through the feed pipe 2, the servo motor 5 is started to work. When the servo motor 5 is started, it drives the main crushing roller 6 at the output end to rotate. While the main crushing roller 6 rotates, the main crushing roller 6 drives the auxiliary crushing roller 7 to rotate inward under the action of surface meshing, so as to crush the raw materials. The crushed raw materials fall to the surface of the screen 402. At this time, the bidirectional motor 401 can be started to work. When the bidirectional motor 401 is started, it can drive the transmission rod 403 at the output ends on both sides to rotate. While the transmission rod 403 rotates, it will drive the eccentric weight block 405 to rotate. During the rotation of the eccentric weight block 405, it is affected by the gravity offset and will generate vibration, so that the screen 402 drives the surface material to vibrate, and the material is screened. The spring 406 will be squeezed during the vibration, and rebound by its own tension, further increasing the vibration amplitude. When the crushing is completed, the box door 3 can be opened to take out the material that has not passed through the screen 402 for secondary processing.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
