Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to a on-site dust removal device. Background Technique

[0002] Concrete production, simply referred to as "concrete": refers to the general term of engineering composite materials in which aggregate is cemented into a whole by cementitious materials. Usually, the term "concrete production" refers to cement concrete production using cement as the cementitious material, sand and stone as aggregates; mixed with water in a certain proportion and stirred. It is also called ordinary concrete production and is widely used in civil engineering. During mixing, it is easy to cause the stirring raw materials to fly up, generating a large amount of dust. The dust is likely to cause environmental pollution. At the same time, operators are in a dust environment for a long time, which is likely to cause damage to the respiratory tract. Therefore, a dust removal device is often required for concrete production.

[0003] The existing on-site dust removal devices for concrete production have the following problems: 1. The device often uses the method of spraying water mist to reduce dust in the surrounding air, but the effect of a single dust reduction method is not ideal, and the dust adsorbed by the water mist will fall to the ground and still generate dust after drying; 2. The dust reduction direction of the device is single. When there is large-area dust, it is necessary for the user to frequently move the device or adjust the direction, which is not convenient to use. Content of the Utility Model
