Description

Technical Field

[0001] This utility model relates to the field of chemical raw material processing technology, and in particular to a chemical raw material crushing equipment. Background Technology

[0002] In the chemical industry, many raw materials (such as ores, fertilizers, and chemical reaction raw materials) need to be refined into particles within a specific particle size range using pulverizing equipment to facilitate subsequent processing such as reaction, dissolution, and mixing. The pulverizing process can significantly increase the surface area of ​​chemical reactions, accelerate the reaction rate, and thus improve product quality and production efficiency.

[0003] For example, Chinese utility model patent application number 202320248453.0 discloses a high-efficiency pulverizing device for chemical raw materials, including a pulverizing box. The upper end of the pulverizing box is provided with a feed hopper. The inner cavity of the pulverizing box is provided with a first pulverizing zone and a second pulverizing zone from top to bottom. Two pulverizing rollers are rotatably arranged in the first pulverizing zone. A guide seat is provided in the second pulverizing zone. A lower conical groove is provided below the guide seat, and a guide hole communicating with the lower conical groove is provided in the middle of the guide seat. A drive shaft is rotatably arranged at the bottom of the pulverizing box, and the drive shaft is driven by a drive motor located at the bottom of the pulverizing box. A grinding roller located in the lower conical groove is provided at the upper end of the drive shaft. A pulverizing and grinding gap is formed between the grinding roller and the lower conical groove. The advantages of this utility model compared with the prior art are: it can perform multi-stage pulverization of raw materials, has high pulverization efficiency, and can completely pulverize chemical raw materials.

[0004] While the above solutions can effectively pulverize chemical raw materials, in actual use, some chemical products will have some moisture attached, making the raw materials relatively wet. Wet raw materials will stick, clog, or adhere to the inner wall of the equipment during the pulverization process, resulting in a decrease in pulverization effect. Moreover, the wet raw materials adhere to the equipment during the pulverization process, making cleaning very difficult. At the same time, the pulverization of chemical raw materials will generate a large amount of dust, especially for easily pulverized materials. Dust exposure will pose a threat to the health of operators and will also affect the quality of the working environment. Therefore, a chemical raw material pulverization equipment is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a chemical raw material crushing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a chemical raw material crushing device, comprising a crushing table, a crushing frame fixedly connected to the top of the crushing table, two crushing shafts rotatably connected to the inner wall of the crushing frame, a plurality of crushing blades fixedly connected to the outer wall of the crushing shafts, a crushing assembly capable of driving the two crushing shafts to rotate relative to each other on the top of the crushing table, a pretreatment frame fixedly connected to the top of the crushing frame, two stirring shafts rotatably connected to the inner wall of the pretreatment frame, stirring blades fixedly connected to the outer wall of the stirring shafts, a stirring assembly capable of driving the two stirring shafts to rotate separately on the outer wall of the pretreatment frame, a dust collection box fixedly connected to the inner top surface of the crushing table, an installation port opened on the back of the dust collection box, a dust collection fan fixedly installed inside the dust collection box by a bracket, and a blocking assembly installed inside the installation port.

[0007] By setting up a crushing component, two shafts rotating in opposite directions can maintain the continuous flow of materials, preventing material from accumulating or forming dead zones in the mixing chamber. In this way, the material is constantly pulled and pushed, preventing equipment blockage caused by material accumulation, thus ensuring smooth operation of the equipment. The inner wall of the crushing frame is equipped with scrapers that intersect with the crushing blades. Their function is to scrape off the raw materials adhering to the crushing blades when crushing chemical raw materials, ensuring that the crushing blades can be used stably for a long time. By setting up a mixing component, the pre-treated chemical raw materials can be fully mixed, ensuring that they can all be heated by the heating plate and ensuring that they are dried evenly. By setting up a barrier component, the dust extraction fan can be operated for a long time, and the blocked dust can also be collected for easy cleaning and maintenance.

[0008] As a further description of the above technical solution:

[0009] The crushing assembly includes a crushing motor fixedly installed on the top of the crushing table. The output end of the crushing motor rotates through the interior of the crushing frame and is fixedly connected to one of the crushing shafts. One end of each of the two crushing shafts rotates through the exterior of the crushing frame and is fixedly connected to a transmission gear.

[0010] The outer walls of the two transmission gears mesh with each other. Through the meshing of the two transmission gears, the two crushing shafts can move relative to each other, so that the material is subjected to forces in different directions in the mixing chamber, which helps to mix the material evenly and can more effectively crush large particles into smaller particles, achieving better crushing uniformity.

[0011] As a further description of the above technical solution:

[0012] The bottom of the crushing frame is fixedly connected to a material discharge frame, and a filter screen is fixedly connected to the inner wall of the crushing frame.

[0014] As a further description of the above technical solution:

[0015] The stirring assembly includes a stirring motor fixedly mounted on one side of the pretreatment frame via a bracket. The output end of the stirring motor is fixedly connected to one of the stirring shafts. One end of each of the two stirring shafts rotatably extends through the outside of the pretreatment frame and is fixedly connected to a connecting gear.

[0016] The outer walls of the two connecting gears mesh with each other. Through the meshing of the connecting gears, the two stirring shafts can rotate separately, which can fully mix the chemical raw materials that need to be pretreated, ensure that the heating is uniform, ensure that the moisture is evaporated, and keep them dry.

[0017] As a further description of the above technical solution:

[0018] Heating plates are fixedly installed on both the front and back sides of the inner wall of the pretreatment frame, and an electric valve is fixedly installed on the bottom of the pretreatment frame.

[0019] The heating plate is equipped with heating wires inside. Through the heating of the heating wires, heat is transferred to ensure the drying of the chemical raw materials in the pretreatment frame. The discharge can be automatically controlled by an electric valve.

[0020] As a further description of the above technical solution:

[0021] The barrier assembly includes a barrier box that is slidably connected inside the mounting port. Several ventilation holes are provided on both sides of the barrier box, and a HEPA filter element is movably installed on the inner wall of the barrier box.

[0022] By using a HEPA filter, the special fiber mesh structure can efficiently filter out tiny particles in the air, removing 99.97% of dust particles larger than 0.3 microns in diameter.

[0023] As a further description of the above technical solution:

[0024] A control box is fixedly installed on the top of the crushing table.

[0025] By setting up a control box, staff can easily control the device.

[0026] As a further description of the above technical solution:

[0027] A dust collection frame is fixedly connected to one side of the dust collection box.

[0028] By setting up a dust collection frame, the suction power can be concentrated, thereby generating greater suction power and ensuring effective dust removal.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0040] Reference Figure 1-5This utility model provides a chemical raw material crushing device, comprising a crushing table 1, a crushing frame 2 fixedly connected to the top of the crushing table 1, two crushing shafts 3 rotatably connected to the inner wall of the crushing frame 2, and several crushing blades 4 fixedly connected to the outer wall of the crushing shafts 3. A crushing assembly capable of driving the two crushing shafts 3 to rotate relative to each other is provided on the top of the crushing table 1. A pretreatment frame 5 is fixedly connected to the top of the crushing frame 2, two stirring shafts 6 rotatably connected to the inner wall of the pretreatment frame 5, stirring blades 7 fixedly connected to the outer wall of the stirring shafts 6, and a stirring assembly capable of driving the two stirring shafts 6 to rotate separately on the outer wall of the pretreatment frame 5. A dust collection box 8 is fixedly connected to the inner top surface of the crushing table 1, and an installation port 9 is provided on the back of the dust collection box 8. A dust collection fan 10 is fixedly installed inside the dust collection box 8 via a bracket. A blocking assembly is provided inside the installation port 9. By setting the crushing assembly, the two shafts rotating in opposite directions can maintain the continuous flow of materials, preventing material accumulation or dead zones in the mixing chamber. In this way, the material is crushed... The intermittent pulling and pushing mechanism prevents equipment blockage caused by material accumulation, ensuring smooth operation. The inner wall of the crushing frame 2 is equipped with scrapers that intersect with the crushing blades 4. These scrapers remove any material adhering to the crushing blades 4 during crushing, ensuring their stable long-term use. The stirring assembly ensures thorough mixing of the pre-treated chemical raw materials, guaranteeing heating by the heating plate 17 and uniform drying. The blocking assembly ensures continuous operation of the dust extraction fan 10 and collects trapped dust for easy cleaning and maintenance. The combined use of the pre-treatment frame 5, heating plate 17, stirring shaft 6, and stirring assembly heats and agitates the moist chemical raw materials, promoting moisture evaporation and keeping the material dry. This effectively prevents adhesion or blockage, improving crushing efficiency, avoiding equipment malfunctions, and facilitating the crushing of chemical raw materials by operators.

[0041] The crushing assembly includes a crushing motor 11 fixedly mounted on the top of the crushing table 1. The output end of the crushing motor 11 rotatably passes through the interior of the crushing frame 2 and is fixedly connected to one of the crushing shafts 3. One end of each of the two crushing shafts 3 rotatably passes through the exterior of the crushing frame 2 and is fixedly connected to a transmission gear 12. The outer walls of the two transmission gears 12 mesh with each other. Through the meshing of the two transmission gears 12, the two crushing shafts 3 can move relative to each other, thereby allowing the material to be subjected to forces in different directions in the mixing chamber, which helps to mix the material evenly and can more effectively crush large particles into smaller particles, achieving better crushing uniformity.

[0042] A material discharge frame 13 is fixedly connected to the bottom of the crushing frame 2, and a filter screen 14 is fixedly connected to the inner wall of the crushing frame 2. By setting the filter screen 14, qualified particles can be discharged, while unqualified particles continue to be crushed, ensuring the quality of the final product. The stirring assembly includes a stirring motor 15 fixedly installed on one side of the pretreatment frame 5 via a bracket. The output end of the stirring motor 15 is fixedly connected to one of the stirring shafts 6. One end of each of the two stirring shafts 6 rotates through to the outside of the pretreatment frame 5 and is fixedly connected to a connecting gear 16. The outer walls of the two connecting gears 16 mesh with each other. By engaging the connecting gear 16, the two stirring shafts 6 can rotate out of phase, fully mixing the chemical raw materials that need to be pretreated, ensuring uniform heating, evaporating moisture, and keeping them dry. Heating plates 17 are fixedly installed on the front and back of the inner wall of the pretreatment frame 5, and an electric valve 18 is fixedly installed at the bottom of the pretreatment frame 5. Heating wires are installed inside the heating plates 17. Through the heating of the heating wires, heat transfer is achieved to ensure the drying of the chemical raw materials in the pretreatment frame 5. The electric valve 18 can automatically control the discharge of materials.

[0043] The blocking assembly includes a blocking box 19 slidably connected inside the mounting port 9. Several ventilation holes 20 are provided on both sides of the blocking box 19. A HEPA filter element 21 is movably installed on the inner wall of the blocking box 19. By setting the HEPA filter element 21, it can efficiently filter the fine particles in the air through the special fiber mesh structure, and can remove 99.97% of dust particles with a diameter greater than 0.3 microns. A control box 22 is fixedly installed on the top of the pulverizing table 1. By setting the control box 22, it is convenient for the staff to control the device. A dust collection frame 23 is fixedly connected to one side of the dust collection box 8. By setting the dust collection frame 23, the suction power can be concentrated, thereby generating greater suction power and ensuring the suction strength.

[0044] Working principle: First, the control box 22 is electrically connected to the dust collector 10, the crushing motor 11, the stirring motor 15, the heating plate 17, and the electric valve 18 to facilitate more convenient control of the device. Then, the chemical raw materials to be crushed can be transported into the pretreatment frame 5. When the raw materials are relatively moist, the operator can start the heating plate 17. The heating wire in the heating plate 17 generates heat to heat the chemical raw materials inside the pretreatment frame 5. At the same time, the stirring motor 15 is started, and the output end rotates to drive one of the stirring shafts 6 to rotate outward. At the same time, the connecting gear 16 on the stirring shaft 6 rotates to drive the connecting gear 16 on the other stirring shaft 6 to rotate, so that the two stirring shafts 6 rotate outward. This allows the stirring blades 7 on the stirring shafts 6 to turn the chemical raw materials, so that the chemical raw materials can better contact the heat released by the heating plate 17, evaporate the moisture on the chemical raw materials, keep them dry, and thus achieve better crushing. This avoids adhesion, blockage, or sticking to the inner wall of the equipment during the crushing process, which would reduce the crushing effect and affect the crushing efficiency.

[0045] Then, the electric valve 18 can be opened to allow the pre-treated chemical raw materials to fall onto the crushing blade 4. Then, the crushing motor 11 is started, and the output end rotates to drive one of the crushing shafts 3 to rotate, which in turn drives the crushing blade 4 to rotate inward. At the same time, through the meshing of the transmission gears 12 on the two crushing shafts 3, the crushing shafts 3 can rotate relative to each other, which in turn causes the stirring blade 7 to rotate inward to crush the chemical raw materials. The opposite rotation directions of the two can cause the material to be subjected to forces in different directions in the mixing chamber. Through the mutual pushing and stirring motion, the material is helped to be mixed evenly, and large particles can be crushed into smaller particles more effectively, achieving better crushing uniformity. Furthermore, through the setting of the filter screen 14, the crushed particles can be discharged, and the unqualified particles are further crushed by grinding, thereby ensuring that the final product has a more uniform particle size.

[0046] After grinding, the crushed particles fall out of the feed frame 13. Since a lot of fine dust is generated during the grinding process, it diffuses from the opening of the feed frame 13. At this time, the vacuum fan 10 can be turned on. The motor inside the vacuum fan 10 drives the fan to rotate and generate suction, which in turn generates suction in the opening of the dust collection frame 23 to suck up the fine dust. After passing through the vent and the HEPA filter 21, the dust will accumulate inside the barrier box 19. After a period of use, the operator can pull out the barrier box 19 and clean out the collected dust from the installation port 9. Then, the barrier box 19 can be reinserted into the installation port 9 to easily clean the device and make it easy to use.

[0047] 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.
