Portable tunnel blasting dust removal device

Abstract

The invention discloses a portable tunnel blasting dust removal device in the technical field of tunnel blasting dust removal, which comprises a movable base, the top of the movable base is fixedly connected with a discharge box, and the inner side of the discharge box is connected with a dipping mechanism for rotating to dip; the right side of the discharging box is provided with an air blowing mechanism which is used for blowing air when the dipping mechanism rotates to a vertical state after dipping, and the dipping mechanism is matched with the air blowing mechanism to perform stable foaming operation in the discharging box; when dust in the tunnel needs to be removed every time, the material dipping mechanism is matched with the air blowing mechanism, foaming liquid is continuously dipped, meanwhile, the foaming liquid is continuously made to generate bubbles smoothly and drifts away in the tunnel, dust is adsorbed to the surfaces of the bubbles, the dust in the tunnel is rapidly removed, the device is better in foaming effect, and the service life of the device is prolonged. The waste of foaming liquid is avoided, the use is simpler and more convenient, and the use in the tunnel is facilitated.

Description

technical field [0001] The invention relates to the technical field of tunnel blasting and dust removal, in particular to a portable tunnel blasting and dust removal device. Background technique [0002] During the tunnel excavation process using the drill and blast method, it is necessary to blast the working face. A large amount of dust will be generated after blasting. Due to the relatively narrow space in the roadway, the wind circulation cannot make the dust escape and settle quickly, which poses a hazard to the health of the on-site workers. Waiting for the natural settlement of the blasting dust will delay the construction period and increase the construction cost. Therefore, it is necessary to use a blasting dust removal device to reduce the dust generated during the blasting process. [0003] In the prior art, when removing dust after tunnel blasting, suction or water spraying is often used to quickly remove dust, but these two methods have shortcomings, such as l...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of portable tunnel blasting dedusting device, to solve the problem in the above-mentioned background technology that when dedusting after tunnel blasting in the prior art, often directly use suction or water spray type to enter and exit the dedusting quickly, but There are deficiencies in these two methods, the suction efficiency is low, and it requires a large cost, and when spraying water, it will cause the tunnel to be soaked, which is not conducive to the operation of personnel. The very necessary problem of the dust removal device in the tunnel
