Respiration air purifying device for mining

Abstract

The invention discloses a respiration air purifying device for mining, and relates to the technical fields of resources and environments. The respiration air purifying device comprises a protection helmet, wherein the outer circle wall of the bottom end of the protection helmet is fixedly connected with a support helmet rim; both sides of the support helmet rim are communicated with telescopic communicating pipes through communicating fixators; the bottom end of each telescopic communicating pipe penetrates through the outer wall of the support helmet rim, and extends to the exterior of the support helmet rim; the outer wall of the part, at the bottom end of the support helmet rim, of each telescopic communicating pipe is sleeved with a protection fixed textile sleeve; the bottom end of each telescopic communicating pipe is communicated with a primary purifying respiration cover; the outer circle wall of one side, near the face, of the primary purifying respiration cover is fixedly connected with a buffer fixed belt. The respiration air purifying device for mining has the advantages that the structure is simple, and the cost is lower; the different purifying methods can be adoptedfor air in different environments, the carrying is relatively convenient, the respiration air purifying device is suitable for mining workers to use, and the working environment of the mining workersis greatly improved.

Description

technical field [0001] The invention relates to the technical field of resources and environment, in particular to a breathing air purification device for mining. Background technique [0002] Production dust is the main harmful factor in underground mines. Many production processes and procedures, such as drilling, blasting, ore dropping, rock loading, transportation, etc., can generate a lot of dust. Workers who inhale this kind of dust for a long time may develop silicosis, coal lung or mixed pneumoconiosis. Methane is often present in mine air, and its main component is methane. In addition, there are harmful gases such as carbon monoxide, nitrogen oxides and hydrogen sulfide. At present, 70% of pneumoconiosis patients in the world are in my country, and the number of deaths from mine pneumoconiosis in my country exceeds the number of deaths due to work. Mine dust concentration is high, the pass rate of dust concentration in underground mines is only 40%-60%, and in ...

Problems solved by technology

[0003] At present, there is a lack of breathing air purification devices developed for mining workers on the market. Due to the constraints of the mine environment and cost, large-scale breathing air purification devices cannot be applied. Generally, the harsh working environment of mining workers cannot be changed, which has caused deep damage to their bodies. Negative impact
