Description

Technical Field

[0001] This utility model relates to the field of chemical production, and in particular to a pulverizer for chemical production. Background Technology

[0002] Chemical production pulverizers are equipment specifically designed for the chemical industry. They use mechanical force to crush chemical materials to a specific particle size. They are characterized by corrosion resistance, explosion-proof properties, fine classification capabilities, and airtightness. They can adapt to the special properties of chemical materials. Using them can improve chemical reaction efficiency, meet the particle size requirements of subsequent processes, handle materials in special forms to ensure production continuity, and meet safety and environmental protection requirements. They are key equipment to ensure efficient, high-quality, safe, and continuous chemical production.

[0003] Existing chemical production pulverizers primarily rely on mechanical forces such as impact, shearing, extrusion, and grinding to overcome the cohesive forces of materials and crush them to the target particle size. Different types of equipment employ different methods, but the overall process follows a feeding-crushing-grading-discharging flow. The material enters the crushing chamber through a sealed device and is crushed by high-speed rotating components. When precise particle size control is required, the crushed material enters a grading system for screening. Qualified material is output through a sealed pipeline, and the equipment is designed with a seal to ensure safety and prevent leakage of special materials.

[0004] However, current chemical production pulverizers still have significant shortcomings in actual operation. The opening and cleaning process of their pulverizing chambers is extremely cumbersome. Most equipment uses bolt fastening or complex snap-fit ​​structures, requiring manual disassembly of multiple parts when opening, which is often time-consuming. During cleaning, due to the presence of dead corners inside the pulverizing chamber and the presence of highly viscous or corrosive chemical materials, special tools are needed for repeated scraping. This not only increases the labor intensity of operators but also easily leads to cross-contamination between different batches of materials due to incomplete cleaning. This complicated operation seriously slows down the production changeover rhythm. Especially in the production of multi-variety, small-batch fine chemicals, frequent shutdowns for cleaning significantly reduce the effective operating time of the equipment, directly affecting the improvement of overall production efficiency.

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.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a chemical production pulverizer, including a fixed platform 1, a support block 2 fixedly connected to the top of the fixed platform 1 for supporting a connecting shaft 4, a pulverizing box 3 fixedly connected to the top of the fixed platform 1 for pulverizing raw materials, a connecting shaft 4 rotatably connected inside the pulverizing box 3 for driving the pulverizing components to move, a pulverizing component provided on the outer wall of the connecting shaft 4 for pulverizing the raw materials, a sealing strip 8 fixedly connected to the top of the pulverizing box 3 for sealing the pulverizing box 3, a driving component provided on one side of the pulverizing box 3 for driving the pulverizing components, a plurality of connecting posts 9 fixedly connected to the top of the sealing strip 8 for connecting the sealing strip 8 and the sealing strip 15, a sliding groove 10 provided inside each connecting post 9 for accommodating a limiting strip 14, a fixing component provided on the outer wall of each connecting post 9 for fixing the sealing strip 8 and the sealing strip 15, a sealing strip 15 rotatably connected to the top of the sealing strip 8 for sealing the pulverizing box 3, and a sealing component provided on the top of the sealing strip 15 for sealing the pulverizing box 3;

[0034] Each fixing component includes a ratchet 11, a rotating block 12, a rack 13, and multiple limiting strips 14. The inner wall of the ratchet 11 is fixedly connected to the inside of the connecting post 9, limiting the rotation direction of the rotating block 12. The inner wall of the rotating block 12 is slidably connected to the outer wall of the connecting post 9, used to fix the sealing strip 1 8 and the sealing strip 2 15. One end of the rack 13 is fixedly connected to the inner wall of the rotating block 12, used to connect the rotating block 12 and the ratchet 11. One side of each limiting strip 14 is fixedly connected to one side of the rack 13, limiting the movement range of the rotating block 12. The crushing component includes multiple fixing plates 5, multiple fixing shafts 6, and multiple crushing blades 7. The inner wall of each fixing plate 5 is fixedly connected to the outer wall of the connecting shaft 4, used to connect the fixing shaft 6. Both ends of each fixing shaft 6 are fixedly connected between the fixing plates 5, used to load the crushing blades 7. One end of each crushing blade 7 is rotatably connected to the outer wall of the fixing shaft 6, used to crush the raw materials. The sealing component includes a sealing cover 16 and a feed inlet. The device includes a pipe 17, a feed tray 18, and a toothed plate 31. The bottom of the sealing cover 16 is fixedly connected to the inner wall of the sealing strip 15 to seal the crushing box 3. The bottom end of the feed pipe 17 is fixedly connected to the top of the sealing cover 16 to introduce raw materials. One side of the feed tray 18 is fixedly connected to the top of the feed pipe 17 to load raw materials. The outer wall of the toothed plate 31 is fixedly connected to the inner wall of the sealing cover 16 to ensure the thickness and diameter of the crushed product and reduce the generation of extremely fine powder. The drive assembly includes a pulley 19, a motor 20, a pulley 21, and a belt 22. The inner wall of the pulley 19 is fixedly connected to one end of the connecting shaft 4 to drive the connecting shaft 4 to rotate. The outer wall of the motor 20 is fixedly connected to the top of the fixed platform 1 to drive the equipment to crush. The inner wall of the pulley 21 is fixedly connected to the output end of the motor 20 to drive the belt 22 to rotate. The belt 22 is located between the pulley 19 and the pulley 21 to drive the pulley 19 to rotate.

[0035] Specifically, when the grinding chamber 3 needs to be opened for cleaning, the operator first only needs to hold the rotating block 12 and rotate it counterclockwise with a little force. This will cause the rack 13 connected to it to slide smoothly along the outer wall of the connecting column 9 under the guidance of the limiting strip 14. As the rack 13 moves, the sealing strip 15, which was originally attached to the sealing strip 8, will gradually be released from its locked state. Then, by holding the sealing strip 15 and gently lifting it upwards, the integrated sealing cover 16 will slowly rise, thus opening the originally sealed grinding chamber 3. The whole process does not require complicated tools, saving both time and effort, and creating convenient conditions for subsequent cleaning work.

[0036] Reference Figure 4 and Figure 5The bottom of the crushing box 3 is fixedly connected to a discharge pipe 23 for discharging the produced product. Multiple connecting strips 24 are fixedly connected to the inner wall of the discharge pipe 23 for connecting to a fixed plate 25. The connecting strips 24 are arranged in a ring array inside the discharge pipe 23. A fixed plate 25 is fixedly connected between the connecting strips 24 for fixing the stirring blade 28 and the motor 30. A rotating shaft 26 is rotatably connected to the top of the fixed plate 25 for driving the stirring blade 28 to rotate. Multiple connecting blocks 27 are fixedly connected to the outer wall of the rotating shaft 26 for connecting the rotating shaft 26 and the stirring blade 28. A stirring blade 28 is fixedly connected to one end of each connecting block 27 for stirring the produced product. A protective shell 29 is fixedly connected to the bottom of the fixed plate 25 for protecting the motor 30. The motor 30 is fixedly connected inside the protective shell 29 to provide power to the stirring blade 28. The output end of the motor 30 is connected to the bottom end of the rotating shaft 26.

[0037] Specifically, the motor 20 starts synchronously the moment the crushing operation begins, and its output shaft drives the rotating shaft 26 to operate efficiently. The stirring blades 28 connected to the outer wall of the rotating shaft 26 rotate accordingly. The blades break up the crushed powder or granular products inside the discharge pipe 23. Products that have just fallen from the crushing box 3 and may clump together due to humidity or static electricity will be completely broken up into uniform pieces by the rotating stirring blades 28. This prevents the products from accumulating and clumping in the discharge pipe 23, ensuring the smooth conveying of the crushed products and allowing the entire production process to proceed continuously and efficiently.

[0038] Working principle: When using the chemical production pulverizer, the raw materials are first poured into the feed tray 18, allowing them to slide into the pulverizing chamber 3 along the feed pipe 17. At the same time, the motor 20 is started, driving the pulley 21 to rotate. The belt 22 drives the pulley 19 to rotate, causing the connecting shaft 4 to start rotating. This causes the fixed shaft 6 to drive the pulverizing blades 7 to start pulverizing the raw materials. During the pulverizing process, the motor 30 is started, driving the rotating shaft 26 to rotate, which in turn drives the connected stirring blades 28 to break up the produced product and prevent the discharge pipe 23 from becoming clogged. When it is necessary to open the pulverizing chamber 3 for cleaning, first hold the rotating block 12 and rotate it counterclockwise, causing the rack 13 to slide along the outer wall of the connecting column 9 under the action of the limiting strip 14, thereby unlocking the sealing strip 15. Then, hold the sealing strip 15 and lift it upwards to lift the sealing cover 16 and open the pulverizing chamber 3.

[0039] 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.
