Flexible dust collecting device for dust unloading of tank truck

Abstract

The invention provides a flexible dust collecting device for tank car dust unloading, and belongs to the technical field of tank car dust unloading and dust collecting devices. The flexible dust collection device comprises a dust return pipeline, a dust collection blank cap and a telescopic dust collection air pipe, the top of the dust return pipeline is communicated with a connecting pipe, a valve body is installed in the connecting pipe, and a mistaken touch prevention mechanism is arranged on the outer side of a valve rod of the valve body. Flanges are fixedly connected to the top of the dust collection blank cap and the connecting pipe and the two ends of the telescopic dust collection air pipe, the two ends of the telescopic dust collection air pipe are fixedly connected with the connecting pipe and the dust collection blank cap respectively through the flanges, a connector is formed in the outer side of the dust return pipeline, the connecting pipe is installed, and the dust collection blank cap covers an external exhaust port of the tank car. The valve body is opened to enable the connecting pipe to be communicated with the ash return pipeline, a large amount of dust generated by exhaust of the tank truck is sucked into the ash return pipeline through negative pressure, and then dust removal is achieved, the field environment cannot be affected, energy is not consumed, and the field environment is facilitated.

Description

technical field [0001] The application relates to the technical field of ash unloading and dust collection equipment for tank trucks, in particular, to a flexible dust collection device for unloading ash on tank trucks. Background technique [0002] At present, the desulfurization and denitrification device of the operation and maintenance project department of Laiwu Iron and Steel Co., Ltd. produces waste desulfurization ash every 2 days. During the second dust loading process, a large amount of dust came out, which affected the site environment and was not conducive to environmental protection work. Contents of the invention [0003] In order to make up for the above deficiencies, this application provides a flexible dust collection device for tank truck unloading, which aims to use the ash return pipe connected to the desulfurization tower system on site, open a port for the ash return pipe, and connect it to the hose of the industrial dust collector, which is flexible ...
