Dust recovery device

Abstract

The invention discloses a dust recovery device which can be continuously used and can improve the collection effect. The dust recovery device comprises a casing, wherein a collection port is formed in the lower part of one side of the casing, an air outlet is formed in the upper part of the other side of the casing, a filter bag board is arranged at the upper part of an inner cavity of the casing, multiple filter bag groups are suspended on the filter bag board, filter bags of the same filter bag group are linearly arranged, the bottoms of all the filter bags are higher than the lower edge of the collection port, an air blowing pipe with a closed lower end is arranged in each filter bag, multiple rings of air blowing holes are formed in each air blowing pipe in the length direction, each air blowing pipe is communicated with a high-pressure air source through a pipeline, an air supply pipe and an electromagnetic valve, the air supply pipe and the electromagnetic valve are arranged on the pipeline, and a dust collecting hopper and a dust collecting drawer matched with the dust collecting hopper are arranged at the lower part of the inner cavity of the casing from top to bottom sequentially. The dust recovery device can be widely applied to various occasions for collection of zinc oxide powder and the like.

Description

technical field [0001] The invention relates to a dust recovery device, in particular to a device for recovering powder produced in the production process of a zinc oxide kiln. Background technique [0002] At present, a traditional dust recovery device has a structure comprising: a housing with a sealed inner cavity, one side of the housing is provided with a collection port, the other side is provided with an air outlet, and the housing is provided with a Cooperate with the exhaust fan, the inlet of the exhaust fan communicates with the air outlet on the shell, several filter bags are hoisted on the upper part of the inner cavity of the shell, and a dust collecting bucket is arranged on the lower part of the inner cavity of the shell. In actual use, due to the unreasonable location of the collection port and the air outlet, the collection effect is not ideal; moreover, when there is too much powder on the filter bag, its adsorption capacity is greatly reduced, so it is nec...

Problems solved by technology

In actual use, due to the unreasonable location of the collection port and the air outlet, the collection effect is not ideal; moreover, when there is too much powder on the filter bag, its adsorption capacity is greatly reduced, so it is necessary to open the shell to remove the dust attached to the filter bag. powder on the bag, therefore, the recovery device cannot be used continuously and is very troublesome to use
