[0002] Belts are commonly used transportation equipment. At the feeding, unloading and transfer points of the belts, the falling of materials and the impact of the airflow carried by the materials on the receiving points will form local pressure increase, generating a large amount of dust. The degree of pressure increase increases with the increase of the height of the falling materials and the angle between the chute and the horizontal plane. The sealing device and technical treatment of the edge seal of the belt and the guide chute are not good, resulting in the induced airflow, air shock wave airflow and belt conveyor traction airflow generated during the falling process, which will spray a large amount of dust inside the equipment from the edge of the equipment. The dust seriously permeates the entire workplace, affecting the hygiene of the working environment.
[0003] The traditional dust removal method is to set an umbrella-shaped dust collection hood at the upper belt head protection cover and the lower belt at an additional material guide trough, and introduce the bag dust collector through the connecting pipe. Although the bag dust removal effect is good, the investment is large. The comprehensive calculation shows that the investment for one material drop point is 30,000 to 50,000 yuan, and the operation and maintenance costs are extremely high. If more dust removal points are required, the cost of the equipment to be laid will reach 2 million to 3 million yuan, which is relatively high. In addition, the main maintenance point of the bag operation is that the bag wears out quickly, and it is basically not worth repairing after wear. The time and financial cost required for replacement are high.
[0004] In view of the above factors, a dust removal device based on the belt conveyor transfer point is specially designed to facilitate maintenance and replacement. The long-fiber polyester filter cartridge or composite fiber filter cartridge has good filtering effect and long service life. Utility Model Content

[0032] like Figure 1-7 As shown, a dust removal device based on a conveyor belt conveyor includes a dust collecting hood, and the dust collecting hood sucks and collects the dust into a dust removal device 1 for treatment. The dust removal device 1 is detachably connected to a discharge part 2 through a connecting pipe 3;
[0033] The dust removal device 1 comprises a base 4, and the base 4 is formed of a steel structure truss to form a supporting steel frame;

[0035] The dust removal unit 7 is detachably connected to the dust removal housing, which is convenient for replacement and adjustment.
[0036] An introduction tube 9 is fixedly provided on the outer wall of the dust removal housing 5 , and the introduction tube 9 is communicated with the dust removal housing 5 .
[0037] In order to facilitate the dust-laden airflow to turn and flow into the ash hopper when it hits the baffle plate during use, the gravity settling hopper 6 is a conical hopper structure, and the bottom opening of the gravity settling hopper 6 is connected to the ash receiving groove, the upper part and the bottom opening of the introduction tube 9 are connected to the dust removal housing 5, and the bottom of the introduction tube 9 extends to the upper end of the gravity settling hopper 6;
