Abstract

The invention discloses an anti-leakage gas discharging device for coal mining. The device comprises a machine seat, a gas pump, a gas concentration sensor and a blower, wherein a support is fixed tothe upper end surface of the machine seat; a first gas delivery pipe is connected to the gas pump; the blower is fixed on the upper end surface of the support; a second gas delivery pipe is connectedto the other end of the gas pump; a first flange is connected to the first gas delivery pipe; the first gas delivery pipe is connected with the gas pump through O-shaped rings; fixing seats are mounted on the gas pump; the movable rings are connected with clamping blocks through first fixing shafts; second fixing shafts are connected to the clamping blocks; and the bottom of each the second fixingshaft is mounted at the top of each the fixing seat. The anti-leakage gas discharging device for coal mining can recycle the gas, so that the emission of greenhouse gas is reduced; and meanwhile, thegas pump is firmly connected with the first gas delivery pipe, so that the gas pump is connected with the first gas delivery pipe without air leakage.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a leakage-proof gas discharge device for coal mining. Background technique [0002] The gas discharge device used in coal mining is to discharge the gas in the mine or mining roadway during the coal mining process, so as to avoid the poisoning of mining workers or the occurrence of gas explosion. However, the existing gas discharge devices used in coal mine development have the following problems: [0003] 1. It is impossible to collect gas, and the emission of gas into the air will cause a greenhouse effect, and the gas cannot be recycled and reused, which wastes resources; [0004] 2. The gas pump will vibrate during operation, causing looseness between the gas pump and the gas pipeline, resulting in air leakage. [0005] In view of the above problems, it is urgent to carry out an innovative design on the basis of the gas discharge device used in the original coal mine de...
