When the dust collection pipe group adsorbs more dust, the electrode device is turned off, and the dust adsorbed on the inner wall of the dust collection pipe group is shaken off by the vibration motor for regular treatment, avoiding the waste of raw material debris mixed in the flying dust, which is more economical.

Description

Technical Field

[0001] The present invention relates to the field of car unloaders, and more particularly to a vertical screw car unloader for preventing dust Background Art

[0002] A vertical screw car unloader is used to insert a screw mechanism into the materials on an open railway car with an opening at the top and rotate it to vertically transport the materials from the feeding end of the screw mechanism to the top. It mainly consists of a screw rotating mechanism, a screw lifting mechanism, a whole machine traveling mechanism, a supporting structure and a driver's cab. According to the different types of supporting structures, the screw car unloader can be divided into a bridge-type screw car unloader, a gantry-type screw car unloader and a cantilever-type screw car unloader. Among them, the gantry type travels on the ground track through the gantry and straddles the railway line for car unloading operations.

[0003] Compared with a dumper, the vertical screw car unloader basically does not damage the car body during car unloading and is suitable for loose and small-particle materials.

[0004] The screw mechanism of the existing vertical screw car unloader adopts a closed structure, so that the transportation of materials in the screw mechanism will not scatter dust to the outside. However, during the car unloading process, the feeding end rotates continuously, and along with the flow of the surrounding materials, a large amount of dust will still be generated during the working process. Since the dust is difficult to control, the working conditions are relatively poor;

[0005] Since most of the dust is in the form of small particles of materials, it is difficult to control when flying, which not only pollutes the environment, but also causes serious waste of materials at the same time

[0006] Therefore, how to provide a vertical screw car unloader that can effectively prevent dust is an urgent problem to be solved by those skilled in the art. Summary of the Invention
