Movable dustproof device for driving face of coal mine

Abstract

The invention discloses a movable dustproof device for a driving face of a coal mine, and relates to the technical field of coal mine dust prevention. The movable dustproof device comprises a dust suction head, a filter box and a dust removal box, the dust suction head is arranged above one side of a mounting table, the dust removal box is fixedly connected to one side of the top surface of the mounting table, and the filter box is fixedly connected to one side of the top surface of the dust removal box; and the dust suction head is integrally arranged in a horn shape, a first connecting ringis arranged on the outer surface of one end of the dust suction head in the circumferential direction, meanwhile, a mounting sleeve is arranged on the outer surface of the other end of the dust suction head in the circumferential direction, first mounting holes are evenly formed in the first connecting ring in the circumferential direction, and semicircular fixing rings are vertically and symmetrically arranged on the outer sides of the mounting sleeve. According to the movable dustproof device, through the arrangement of an electric telescopic rod, a gear disc, a gear rack, a first air cylinder, a second air cylinder, the dust removal box, the filter box, a filter layer and a dust outlet pipe and mutual cooperation of the components, the movable dustproof device is convenient to use, rapid and efficient dust removal can be conducted, water resources in the movable dustproof device can be repeatedly utilized, and waste of the water resources is avoided.

Description

technical field [0001] The invention belongs to the technical field of dust prevention in coal mines, and in particular relates to a movable dust prevention device for coal mine excavation working faces, which is mainly used for dust prevention when the coal mine excavation working faces are working. Background technique [0002] Excavation face, also known as head-on excavation, means that when preparing for the mining face, a roadway is firstly mined. This roadway includes functions such as coal exploration, coal excavation, water exploration, and gas exploration. , a separate single-headed roadway supplemented by other geological conditions, without an independent ventilation system, and without a direct passage to the ground, it needs to be supported by the top of the roadway and the two sides, generally mechanical excavation and gun excavation, in the excavation face During the working process, it is necessary to use a dust-proof device for dust reduction treatment. At ...

Problems solved by technology

[0003] The purpose of the present invention is to provide a mobile dust-proof device for coal mine excavation working face. Through the setting of the electric telescopic rod, the dust suction head can be inserted into the excavation working face for dust suction during work. With the setting, under the action of the second cylinder, the angular movement of the dust suction head in the horizontal direction can be realized, and the vertical movement of the dust suction head can be realized through the setting of the first cylinder, which can achieve targeted and fast dust collection , through the setting of the dust removal box, the dust inhaled by the vacuum head can be washed and dust removed, and the water in the dust removal box can be filtered through the setting of the filter box, which can be used for reuse of water, reducing the waste of water resources and solving the problem of The existing dust-proof device is difficult to work in a narrow space, the entire dust-reduction efficiency is low and the dust-reduction is not complete, and the existing dust-proof device will use a large amount of water during dust reduction, resulting in the waste of water resources
