In order to ensure the dust removal effect, a plurality of filter holes 3 are evenly and circumferentially arranged on the box wall of processing box 1, and the filter holes 3 can effectively intercept dust particles generated in the processing process. In addition, a dust hood 4 is circumferentially sleeved on the outside of the processing box 1, the dust hood 4 cleverly covers the above-mentioned filter holes 3, and ensures that the dust can be effectively sucked. One end of the dust hood 4 is also connected with a dust removal pipeline 5, and the dust sucked through the pipeline is transported to the dust removal system for treatment. In order to facilitate material discharge, a discharge port 6 is specially designed at the bottom end of the processing box 1, and a collecting box 7 for collecting processed materials is arranged directly below the discharge port 6, so that efficient separation and collection of materials are realized.

[0023] Specifically, the top end of the processing box 1 is provided with a feed inlet 8, and the top end of the feed inlet 8 is connected with a horn-shaped feed channel 9;The length of the crushing roller 2 is greater than the length of the feed inlet 8, and the width between the top ends of the two crushing rollers 2 is greater than the width of the feed inlet 8.

[0024] In this embodiment, the top end of the processing box 1 is specially designed with a feed inlet 8, and the top end of the feed inlet 8 is connected with a horn-shaped feed channel 9, which helps the material to enter the processing box more smoothly. Specifically, the top end of the feed inlet 8 is closely connected with the horn-shaped feed channel 9, ensuring the smoothness and uniformity of the material when entering. In addition, the length of the crushing roller 2 is carefully designed to be significantly greater than the length of the feed inlet 8, which can ensure that the material can be fully processed when entering the crushing area. At the same time, the width between the top ends of the two crushing rollers 2 is also accurately calculated to ensure that it is greater than the width of the feed inlet 8. The purpose of this design is to prevent the material from being blocked when entering the crushing roller, thereby improving the efficiency and stability of the entire processing process.

[0025] Specifically, the upper side of the cavity of the processing box 1 is provided with a baffle 10, and the baffle 10 prevents the magnesite from bypassing the crushing roller 2.

[0026] In this embodiment, a baffle plate 10 is specially designed and installed on the upper side of the processing box 1 cavity. The position of the baffle plate 10 is carefully calculated to ensure that it can effectively cover the upper part of the crushing area. The main function of the baffle plate 10 is to prevent magnesite from bypassing the crushing roller 2 during the crushing process, ensuring that all materials can be fully processed through the crushing roller 2. During the crushing process, materials may attempt to bypass the crushing roller 2, resulting in insufficient crushing and affecting product quality. The arrangement of the baffle plate 10 can effectively guide the material to move along the correct path, ensuring that all materials can be processed through the crushing roller 2, thereby improving crushing efficiency and product quality. The material and shape of the baffle plate 10 are carefully selected to ensure that it has high durability and stability during long-term use, while not hindering the normal flow and processing of materials.

[0028] In this embodiment, one end of the dust removal pipeline 5 is connected to the induced draft fan 11, which provides power support for the entire dust removal system. The induced draft fan 11 uses its powerful suction to suck the dust generated during the processing through the filter hole 3 and the dust suction cover 4 into the dust removal pipeline 5, and then transported to the subsequent processing device through the dust removal pipeline 5. In addition, a branch pipeline 12 is specially designed and installed below the dust removal pipeline 5. One end of the branch pipeline 12 is connected to the dust removal pipeline 5, and the other end is connected to a regional dust removal cover 13. The position of the regional dust removal cover 13 is carefully designed to be above the collection box 7. The main function of the regional dust removal cover 13 is to capture the dust that may escape above the collection box 7, preventing these dust from entering the air again during the collection process, causing secondary pollution. The design of the regional dust removal cover 13 should ensure that it can effectively cover the upper area of the collection box 7, while not hindering the normal collection and processing of materials. The arrangement of the branch pipeline 12 and the regional dust removal cover 13 further improves the efficiency and effect of the entire dust removal system, ensuring that the dust generated during the processing can be thoroughly collected and processed.

[0029] Specifically, the induced draft fan 11 is provided with an exhaust pipe 14, and a filter cartridge 15 is arranged at the end of the exhaust pipe 14.

[0030] In this embodiment, an exhaust duct 14 is specially designed and installed at the outlet of the induced draft fan 11. One end of the exhaust duct 14 is tightly connected to the induced draft fan 11, and the other end is connected to a filter cartridge 15. The main function of the filter cartridge 15 is to further purify the gas discharged from the induced draft fan 11. During the dust removal process, although most of the dust has been filtered and collected, a small amount of fine dust particles may still be discharged with the airflow. The filter cartridge 15 can effectively capture these fine dust particles, ensuring that the discharged gas meets environmental protection requirements and avoiding environmental pollution. The material and structure of the filter cartridge 15 are carefully designed to ensure high filtration efficiency and long service life. At the same time, the replacement and maintenance of the filter cartridge 15 should also be designed to be simple and easy to perform to ensure the long-term stable operation of the entire dust removal system.

[0031] Specifically, the pipe wall of the discharge port 6 extends from top to bottom and from the outside to the inside.

[0032] In this embodiment, the pipe wall design of the discharge port 6 has been carefully optimized. Its shape and angle have been precisely calculated to ensure smooth material flow during discharge while effectively preventing dust spillage. The pipe wall of the discharge port 6 extends from top to bottom and from the outside to the inside. This design effectively reduces airflow turbulence and prevents dust from escaping due to airflow. The material and thickness of the pipe wall of the discharge port 6 have been carefully selected to ensure high durability and stability during long-term use. Simultaneously, the design of the discharge port 6 also considers the flowability of the material and the convenience of collection, ensuring that the material can be smoothly discharged and collected in the collection box 7. The pipe wall design of the discharge port 6 further improves the dust removal effect and material handling efficiency of the entire dust removal device, ensuring smooth processing and a clean environment.

[0033] Working principle: When this utility model is in operation, the material enters the device through the feed port 8 at the top of the processing box 1. The feed port 8 is connected to a funnel-shaped feed channel 9. This design can guide the material into the processing box 1 evenly and smoothly, avoiding material accumulation or blockage.

[0034] Material entering the processing chamber 1 is pulverized between two horizontally positioned crushing rollers 2. The crushing rollers 2 are driven by a motor, enabling efficient pulverization of the material. The length and width of the crushing rollers 2 are optimized to ensure that the material fully contacts the rollers and is completely pulverized. Simultaneously, a baffle 10 is installed on the upper side of the processing chamber 1 to effectively prevent material from bypassing the crushing rollers 2, ensuring that all material undergoes pulverization.

[0035] During the crushing process, a large amount of dust is generated. The walls of the processing chamber 1 are evenly distributed with several filter holes 3, which can initially intercept some dust particles. Simultaneously, a dust collection hood 4 is fitted outside the processing chamber 1, covering all the filter holes 3, and drawing the dust intercepted by the filter holes 3 into the system through a dust collection pipe 5. An induced draft fan 11 is connected to the dust collection pipe 5, and the fan 11 uses strong suction to transport the dust through the dust collection pipe 5 to subsequent processing devices.

[0036] A branch pipe 12 is provided below the dust collection pipe 5, and a regional dust collection hood 13 is provided at the end of the branch pipe 12, which is located above the collection box 7. The regional dust collection hood 13 can further capture dust that may escape from above the collection box 7, preventing secondary pollution. At the same time, the air outlet of the induced draft fan 11 is connected to an exhaust pipe 14, and a filter cartridge 15 is provided at the end of the exhaust pipe 14. The filter cartridge 15 can further purify the gas discharged from the induced draft fan 11, ensuring that the emitted gas meets environmental protection requirements.

[0037] The pulverized material is discharged through the outlet 6 at the bottom of the processing chamber 1. The pipe wall of the outlet 6 is designed to extend from top to bottom and from the outside to the inside. This design can effectively reduce airflow disturbance and prevent dust from overflowing. A collection box 7 is located directly below the outlet 6 to collect the pulverized material, achieving efficient separation and collection of the material.
