Flue ash removal device and system

Abstract

The invention provides a flue ash removal device and system. The flue ash removal device comprises a guide rail assembly, a rotating shaft assembly and a winch assembly, wherein the guide rail assembly is arranged on the inner wall of a flue body; the winch assembly is arranged on the upstream section of the flue body; through the guide rail assembly, the rotating shaft assembly is limited to rotate in the extending directions of guide rails and sweeping arms is driven to rotate; then, sweeping hammer assemblies are driven to scrape and sweep the inner wall of the flue body; accumulated ash on the inner wall of the flue body is raised and taken away through the flow of flue gas; and consequently, the purpose of sweeping is fulfilled. In addition, arc-shaped plates are arranged on the sweeping arms and the multiple sweeping hammer assemblies are arranged on the arc-shaped plates in an array, so that the sweeping area can be increased and the sweeping effect can be improved; the sweeping hammer assemblies are designed to be of a foot-shaped structure, so that the accumulated ash can be raised and the sweeping effect can be improved; and windward plates are arranged among the sweeping arms, so that the windward area of the rotating shaft can be increased and the sweeping effect can be further improved. The flue ash removal device is novel in structure, simple to operate, economical and efficient.

Description

technical field [0001] The invention relates to the technical field of flue dust removal, in particular to a flue dust removal device and a dust removal system. Background technique [0002] The wind flue is widely used in steel manufacturing, environmental dust removal and other industries. Its function is to guide the flue gas (such as exhaust gas, hot gas, etc.) to flow according to the specified route. Because the flue gas contains a lot of dust, it will often cause a large amount of dust to accumulate in the lower part of the flue. On the one hand, it will reduce the cross-sectional area of ​​the flue and affect the flow of flue gas. On the other hand, it will increase the weight of the flue and increase the density of the flue. The load of itself and the flue support will cause the flue to bend and sink or even the support to fail. [0003] In the prior art, there are two commonly used air flue ash cleaning methods. One is to set manholes and ash discharge holes on th...
