Description

Technical Field

[0001] This utility model relates to the technical field of dust removal equipment, and in particular to a dust removal device for a mobile ore unloading car. Background Technology

[0002] In the original ironmaking processes of the steel industry, the mobile unloading cars on the troughs of systems such as raw material premixing systems, sintering combustion receiving systems, and blast furnace ore and coke receiving systems are not equipped with dust removal systems. At present, dust removal for mobile unloading cars mainly adopts mobile ventilation duct dust removal technology. The load applied to the mobile unloading cars by the newly added mobile ventilation duct dust removal pipes and their supports is often greater than 2.5 tons, far exceeding the load-bearing limit of about 1.0 ton for old mobile unloading cars. If traditional mobile ventilation duct dust removal technology is adopted, the mobile unloading cars need to be replaced as a whole, which is very expensive. At the same time, if the original mobile unloading cars are replaced as a whole, the construction period required for equipment dismantling, hoisting and replacement, as well as the demolition and repair of existing buildings, far exceeds the planned equipment shutdown time, and the losses to the company's production are also incalculable.
