Dust control device and method

Abstract

The invention discloses a dust control device and method. The dust control device comprises a material storage box arranged at the material use place, and connected with a feed pipe for receiving andstoring materials, a first dust controller of which the inlet is communicated with an inner cavity of the material storage box through a first air inlet pipe and the outlet is connected with one end of a first air outlet pipe, a second dust controller of which the inlet is connected with the other end of a second air inlet pipe, and the outlet is connected with a second air outlet pipe and a dustabsorbing cover arranged at the material combination place, and connected with the second air inlet pipe through a dust exhaust pipe, wherein the other end of the first air outlet pipe is connected with one end of the second air inlet pipe. By adopting the dust control device and method, dust control can be performed for the first time when the materials are transported to the material storage box, the dust control can be further performed for the second time when the materials are used at the material use place, to reduce environmental pollution and ensure good working environments and normaloperation of equipment.

Description

technical field [0001] The invention relates to the field, in particular to a dust control device and method. Background technique [0002] In some places where bulk materials are transported by means of wind, air, etc., no matter whether the materials are transported to the on-site stocker for storage, or the materials are used on-site, it is easy to generate large dust, thus polluting the atmosphere Environment and employee job environment. For example, the cold core machine used to produce sand cores in the foundry industry uses pneumatic conveying of molding sand. When the molding sand is pneumatically conveyed to the sand storage box for storage, dust will be generated. Dust is also generated. For another example, mines, metallurgy, casting, machining, quarry crushing, casting shot blasting, production of water, ceramics and other places will also generate a lot of dust when transporting materials and using materials. [0003] In order to deal with the dust in these ...
