Excavation mobile dust removal device

Abstract

The invention discloses a tunneling movable dust removal device which comprises a ventilating pipe. The ventilating pipe is connected with a dust removal chamber, the two sides of the dust removal chamber are respectively provided with a traveling device, a spray device is arranged in the dust removal chamber, a water collecting tank is arranged below the dust removal chamber, an air outlet is arranged on the dust removal chamber, an inlet of a water suction pump is connected with the water collecting tank, and an outlet of the water suction pump is connected with the spray device. A filtered water dust removal net is obliquely arranged below a dust outlet of the ventilating pipe, and the lower end of the filtered water dust removal net is provided with a silt chute outlet. A silt sediment tank is arranged below the filtered water dust removal net, one end of the silt sediment tank is provided with a grid water outlet, a desilting overflow weir is arranged near the grid water outlet, and a silt-flushing open-close channel is arranged near the desilting overflow weir. The dust removal device disclosed by the invention can move along with the moving of a tunneling machine, so that the effect of dust removal is enhanced. The dust removal device can effectively absorb 90% and more of dust in front of a tunnel face, so that a good sight and relatively clean air are provided for drivers of tunnel boring machines and other operators.

Description

technical field [0001] The invention relates to the field of dust removal devices, in particular to a tunneling mobile dust removal device suitable for dust reduction and dust removal during the tunnel excavation process of a cantilever roadheader. Background technique [0002] At present, the EBZ series cantilever roadheader produced by my country itself, the internal and external spray dust removal equipment equipped with the factory can not effectively reduce the dust in the tunnel excavation operation, the actual dust in the underground tunnel excavation The concentration is high and the visibility is low, which not only affects the progress of the tunnel excavation of the roadheader, but also has a certain impact on the health of the workers in the tunnel. However, the use of bulky roadway dedusting fans is expensive, and it is difficult to promote because it is not suitable for national conditions. [0003] In the existing solutions, there is a method of spraying and d...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a tunneling mobile dust removal device, which can overcome the existing technical problem of poor dust removal effect of internal and external sprays, and does not need to greatly increase the length of the dust suction soft air cylinder, and the dust removal water can be recycled , in the preferred solution, it is also possible to treat the sediment generated during the dust removal process on site
