Dust suction and dust fall integrated device for mine shaft

Abstract

The invention discloses a dust suction and dust fall integrated device for a mine shaft. The dust suction and dust fall integrated device comprises a bottom plate, a water tank, a dust fall box, a piston cylinder and a dust suction hood; a bracket is arranged at the upper end of the bottom plate, a motor is arranged on the inner side of the bracket, a threaded sleeve is arranged on the right sideof the motor and fixedly connected with the bracket, the inner side of the threaded sleeve is in threaded connection with a threaded rod, and the end, penetrating through the bracket, of the threadedrod is fixedly connected with the lower end of the dust suction hood; and the upper end of the piston cylinder communicates with the dust fall box, the dust fall box is fixedly mounted on the inner side of the bracket, a rotating rod stretches into the dust fall box, and stirring rods are symmetrically mounted on the rotating rod. According to the dust suction and dust fall integrated device for the mine shaft, the design is novel, the arranged threaded rod drives the dust suction hood to rotate and simultaneously drives the dust suction hood to move up and down, the dust suction range of thedust suction hood is expanded, the dust fall effect is improved, gas after being subjected to dust adsorption is exhausted through an arc-shaped spraying tube, the arc-shaped spraying tube drives an L-shaped spraying tube to rotate, energy can be saved, the atomized water spraying range can be expanded, and the dust fall effect is improved.

Description

technical field [0001] The invention relates to the field of mining, in particular to a dust collection and dust reduction integrated device for mines. Background technique [0002] A large amount of dust is produced during the underground production of coal mines. Miners operating in a densely dusty environment will on the one hand cause safety accidents due to greatly reduced vision, and on the other hand will increase the risk of miners suffering from pneumoconiosis. For a long time, the main use of spray dust suppression in mines is to achieve the purpose of dust prevention. The spray dust suppression device mainly chooses arc-shaped spray device and linear spray device according to the section structure of the roadway. This type of device is mainly fixed on the top of the roadway. The high-altitude operations required in the medium and high-altitude operations also bring greater safety hazards to the operations. In addition, the atomizing nozzles are all arranged on t...

Problems solved by technology

The spray dust suppression device mainly chooses arc-shaped spray device and linear spray device according to the section structure of the roadway. This type of device is mainly fixed on the top of the roadway. The high-altitude operations required in the medium and high-altitude operations also bring greater safety hazards to the operations

In addition, the atomizing nozzles are all installed on the top of the roadway, which makes it difficult for the nozzle range to meet the use requirements, resulting in the spray not being able to cover the entire roadway section and not achieving efficient dust reduction.
