Accelerating-air-flow dust exhaust apparatus for rock tunnel construction in cold region

Abstract

The invention discloses an accelerating-air-flow dust exhaust apparatus for rock tunnel construction in a cold region. The dust exhaust apparatus comprises a dust suction port, an accelerating air circulation host, moving wheels, a suction machine and a water tank. The dust suction port is embedded in the middle end of the front surface of the accelerating air circulation host. The moving wheels are arranged at the bottom of the accelerating air circulation host. The accelerating air circulation host and the suction machine form an integrated structure. The water tank is installed above the suction machine and slide by two circulating devices. Circulation of the air inside a rock tunnel in a cold region and external air is accelerated, so that the internal temperature of the rock tunnel inthe cold region is increased and the dust can be exhausted effectively by the dust exhaust apparatus. A low-row collecting mechanism collects free silicon dioxide in air and reaction is carried out on the free silicon dioxide by a reaction box to generate polyoxometalates being a novel multifunctional catalyst, so that the application value of the dust exhaust apparatus is enhanced. Suction of the silicon dioxide by the construction staff is avoided and thus the health of the construction staff is ensured.

Description

technical field [0001] The invention relates to the field of tunnel construction equipment, in particular to a dust suction device for accelerating air flow. Background technique [0002] In the process of blasting rock tunnels in cold regions, there will be a lot of dust. At this time, dust collection devices need to be used to deal with the dust. The current dust collection devices for tunnel construction have the following disadvantages: [0003] 1. During the blasting process of the rock tunnel in the cold area, due to the long-term heat loss inside the rock in the cold area, the temperature inside the tunnel is lower than the outside world, and the dust inside the tunnel is frost heaved, and it is difficult for the dust suction device to suck the dust. [0004] 2. The rock contains free silicon dioxide, and the vacuum device cannot further process the free silicon dioxide. After the vacuuming is completed, the dust of free silicon dioxide will be inhaled by the construc...

[0003] 1. During the blasting process of the rock tunnel in the cold area, due to the long-term heat loss inside the rock in the cold area, the temperature inside the tunnel is lower than the outside world, and the dust inside the tunnel is frost heaved, and it is difficult for the dust suction device to inhale the dust

[0004] 2. The rock contains free silicon dioxide, and the vacuum device cannot further process the free silicon dioxide. After the vacuuming is completed, the dust of free silicon dioxide will be inhaled by the construction workers, causing silicosis in the construction workers and endangering the health of the construction workers.
