Pulse-type filter cylinder dedusting and ventilating apparatus

Abstract

The invention relates to a pulse-type filter cylinder dedusting and ventilating apparatus, of which the main structure is composed of following components: a dedusting box, filter cylinders, an air inlet cover, a pedestal, an air duct, a centrifugal fan, a motor, an exhausting pipe, a dust box, a differential pressure mechanism, a differential pressure meter, an axial flow fan, a dust collection funnel and a pulse electromagnetic valve. The apparatus, aiming to the defects that the electric shovel coal mining operation at an open pit coal mine generates much crushed coal and dust and is serious in raise dust, is designed with combination of machinery with electronic control. The apparatus is advanced in design and is compact in structure. The pulse electromagnetic valve can continuously feed compressed air into the dedusting box. The multiple filter cylinders achieve a good dedusting effect and the apparatus can reach 99% in dedusting rate. The apparatus has the functions of not only dedusting but also ventilation, is a very excellent dedusting and ventilating apparatus, and can not only be used for dedusting and ventilation of the coal mining operation at the open pit coal mine but also be used for dedusting and ventilation of other coal mining operations.

Description

technical field [0001] The invention relates to a pulse type filter cartridge dedusting ventilation device, which belongs to the technical field of open-pit coal mining and design and manufacture of supporting equipment. Background technique [0002] The most widely used equipment in open-pit coal mining is the electric shovel. The electric shovel has the advantages of large excavation area, fast speed and high efficiency. Dust, especially in the dry season, or in spring, autumn, and winter, when there is less rainfall and the air is dry, these dusts will form flying dust, which not only pollutes the environment, but also damages mechanical parts and electrical equipment, and even poses a safety hazard. [0003] Some of the existing excavation electric shovels are also equipped with dust removal equipment, but these equipment have simple structure, low power, poor dust collection and dust removal capabilities, and cannot play the role of dust collection and dust removal, and...

[0002] The most widely used equipment in open-pit coal mining is the electric shovel. The electric shovel has the advantages of large excavation area, fast speed and high efficiency. Dust, especially in the dry season, or in spring, autumn, and winter, when there is less rainfall and the air is dry, these dusts will form flying dust, which will not only pollute the environment, but also damage mechanical parts and electrical equipment, and even pose a safety hazard

[0003] Some of the existing excavation electric shovels are also equipped with dust removal equipment, but these equipment have simple structure, low power, poor dust collection and dust removal capabilities, and cannot play the role of dust collection and dust removal, and have become a part of the operation of the electric shovel. Big hidden dangers, even causing safety accidents, have seriously affected the efficiency and safety of electric shovel mining operations, and become a difficult problem to be solved
