Dust removing device for crushing building wastes

Abstract

The invention discloses a dust removing device for crushing building wastes. The dust removing device comprises a building-waste crushing box and also comprises a connecting pipeline, a cloth-bag dust remover, a drying device, a water tank, a ring-shaped exhausting pipe and a fan, wherein the top part of the building-waste crushing box is communicated with a dust conveying pipeline; the bottom part of an inner cavity of the connecting pipeline is communicated with the other end of the dust conveying pipeline; the inner cavity of the connecting pipeline is provided with a primary filtering net and a secondary filtering net in sequence from bottom to top; the top part of the inner cavity of the connecting pipeline is communicated with the air inlet end of the cloth-bag dust remover by a communicating pipe; the ring-shaped exhausting pipe is erected at the lower part of the inner cavity of the water tank; a grid is fixedly erected at the middle part of the inner cavity of the water tank; and the air outlet end of the cloth-bag dust remover is communicated with the ring-shaped exhausting pipe by a conveying pipeline. The dust removing device disclosed by the invention has the advantages that the structure is simple, the production cost is low, the use is convenient, the dust removing effect for dusts exhausted by the building-waste crushing box is good, and the influence of the dust on the atmospheric environment is avoided, so that the dust removing device is suitable for promotion and use.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a dust removal device for crushing construction waste. Background technique [0002] With the development of social economy, my country continues to deepen urban construction, because the modern urban construction in my country is mainly based on concrete buildings, and concrete buildings have a certain service life limit due to aging problems; the service life of concrete buildings in my country is mostly designed to be 70 Around 2000, these old buildings continued to be demolished and rebuilt; after the demolition of concrete buildings, a large amount of construction waste will be generated. The amount of construction waste is the largest. Most of the construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is piled up or landfilled in the open air, consuming a lot of construction funds such as land acquisition fees and garbage remov...

[0002] With the development of social economy, my country continues to deepen urban construction, because the modern urban construction in my country is mainly based on concrete buildings, and concrete buildings have a certain service life limit due to aging problems; the service life of concrete buildings in my country is mostly designed to be 70 Around 2000, these old buildings continued to be demolished and rebuilt; after the demolition of concrete buildings, a large amount of construction waste will be generated. The amount of construction waste is the largest. Most of the construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is piled up or landfilled in the open air, consuming a lot of construction funds such as land acquisition fees and garbage removal fees; these construction waste It is extremely difficult to degrade, and the land filled with construction waste can only be used for a long period of time, causing huge pollution to the environment

[0003] Construction waste is easy to produce a large amount of dust during the crushing process. If the dust is directly discharged into the atmosphere, it will pollute the air in the atmosphere. Therefore, we need to design a dust removal device for construction waste crushing
