[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] During the production process, the iron and steel metallurgical industry often produces various dusty fumes. In order to improve the workshop environment to meet people's health needs and meet the increasingly stringent national environmental protection standards, an environmental dust removal system must be set up. Among them, the bag dust removal system is the most widely used dust removal device for environmental dust removal.

[0004] Most of the existing steel industries adopt the "blast furnace-converter" long-process production technology, in which the blast furnace ore trough, coke trough, converter high-span high-level silo, etc. all need to use mobile unloading carts to unload various materials into the silo.

[0005] At present, the dust removal process for unloading materials from the mobile unloading trolley to the silo generally adopts the form of mobile ventilation slots + silo vacuum dust removal, and then the smoke is transported to the bag dust collector for purification through the dust removal pipeline. However, this dust removal method has serious smoke overflow, resulting in poor dust removal effect and affecting the workshop environment; and the dust removal pipeline is long, which makes the mobile unloading trolley have a large system resistance during operation.

[0006] Although some dust removal devices in the prior art are designed to be sealed, they require the cooperation of rollers, sealing belts, dust hoods, and silos to achieve sealing, and have a complex structure. The mobile unloading trolley needs to unload back and forth, which makes its stability poor. Utility Model Content
