Dust collection device used at explosion site

The invention provides a dust collection device used at an explosion site. The dust collection device comprises a fixing cylinder, an exhaust fan, a support rack, a cloth cylinder, a hollow plate, a filtering net, a rotating column, a fixing sleeve and a support plate, wherein the fixing cylinder is fixed at the upper end of the support rack; the exhaust fan is mounted inside the fixing cylinder through a fixing rod; the support rack is fixed at the left upper end of a water tank; the upper end of the cloth cylinder is connected with the fixing cylinder; the lower end of the cloth cylinder isconnected with the upper end surface of a hollow plate; the hollow plate is fixed on the inner wall of the water tank; the hollow plate is arranged below the filtering net; the filtering net is fixedat the lower part inside the water tank; the rotating column is mounted inside the fixing sleeve; the fixing sleeve is fixed at the right upper end of the water tank; the support plate is fixed at theupper end of the rotating column; a dust collection jackhammer is arranged on the support plate. Due to the design, the purposes that the dust collection area is increased, the dust collection efficiency is improved, and in addition large-density dust is rapidly and effectively sucked and treated can be achieved, and the dust collection device is wide in operation range, convenient to operate, good in dust collection effect and simple in structure.
