Dust absorbing and treating device for building site

Abstract

The invention discloses a dust absorbing and treating device for a building site. The dust absorbing and treating device comprises a shell, a lower partition is fixedly connected below the inside of the shell, a motor seat is fixedly connected on the left side above the lower partition, a motor is fixedly connected above the motor seat, an output end of the motor is fixedly connected with a driving bevel gear, a longitudinal rotating shaft is rotatably connected in the middle above the lower partition through bearing and is of a tubular structure, a driven bevel gear is fixedly connected below the longitudinal rotating shaft, and the driven bevel gear and the driving bevel gear are meshed. Compared with the prior art, the dust absorbing and treating device has the advantages that the device is simple in structure and convenient to use; through omnibearing dust absorbing, dust in each direction of the device can be absorbed more cleanly; the device combines two modes of dust collection for convenience of treatment with water spraying to lower dust content in air, so that environment of the building site is better, and the device is worthy of popularization.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a dust absorption and treatment device for a construction site. Background technique [0002] In the demolition of old buildings, whether it is manual demolition or directional blasting, dust pollution is often caused, especially in the weather with high wind and dry objects, the dust pollution is more prominent. The main sources of dust in building construction are: excavation and removal of muck, backfill, exposed material piles, garbage thrown from top to bottom during demolition construction, piled construction waste, muck removal and on-site mixing of concrete Wait. Flying dust includes three components: falling dust (particle size >100 μm), floating dust (particle size 10-100 μm), and inhalable particulate matter (particle size <10 μm). Flying dust pollution is one of the most important pollutants in the air, and it has become the primary air pollutant in most areas of our c...

[0003] However, the dust reduction schemes used in construction sites are generally sprinkling water on a large area, and the vehicles are sprayed and cleaned with water. The main method is to use the spray water to absorb the floating dust in the air to achieve the effect of dust reduction. There is too much water in the ground area of ​​the site, which makes the ground muddy and difficult to walk, which will have a certain impact on the construction; moreover, a large amount of spray water is required for spraying during the dust reduction process, which will cause waste of water resources, even the commonly used dust reduction fog gun device, will cause a waste of water resources

Nowadays, small-scale dust collectors generally use cloth bags or electrostatic dust collectors. If they are used in a scene with a large head, the small bag dust collectors consume too quickly and require frequent replacement of filter elements. The pressure loss is large, and the filtration efficiency is significantly reduced; and the small electrostatic precipitator has a complex structure, high maintenance and use costs, and is not suitable for filtering large-sized dust

[0004] For this reason Chinese patent (authorized announcement: CN206483245U) discloses a kind of construction site temporary dust suppression device, but the dust removal effect of this device is still not good
