Description
Technical field
The utility model relates to a kind of positive-pressure type mining dust-proof mouth mask, is specifically related to a kind of Individual protection equitment towards mine down-hole working face and high dust work place.
Background technology
Coal is the basic energy important in process of industrialization, China be in the world rare several take coal as one of country of main energy sources, be also maximum coal production and country of consumption in the world.Related data shows, within 2013, Chinese coal consumption figure is 36.1 hundred million tons.But due to the particularity of mining production process, in its recovery process, dust harzard has become the outstanding problem in safety in production.The healthy of coal miner in dust in mine serious threat, and more serious also dust explosion can occur, and causes serious accident.Have statistics display, national colliery meets nearly 2,650,000 people of dirt personnel, according to measuring and calculating, has 5.7 ten thousand people to suffer from pneumoconiosis every year, then has more than 6000 people because of Death from Pneumoconiosis, and be the twice of industrial accident death toll, pneumoconiosis has become invisible " killer ".
Dust refers to the solid particle that can be suspended in air for a long time, and Mine Dust is the general name of all kinds of solid matter fine particles that colliery produces in process of production, also known as being industrial dust.The coal particles that diameter is less than 1mm can participate in coal-dust explosion, and this part dust is called full dirt; Simultaneously diameter is less than the rock of 5 μm and coal particles and can enters human lung and cause pneumoconiosis, and this part dust is called respirable dust.Mine is in driving and recovery process, and the operations such as rock drilling, explosion, pillar, transport, ore reduction, screening all can produce dust, workers with long time operation in such a case in a large number, sucks industrial dust and then easily suffers from pneumoconiosis.Dust content is higher, and morbidity is shorter for the length of service, and the development degree of pathology is faster; The granularity of mine dust is less, and decentralization is higher, larger to the harm of human body.
Usually, be prevention and the generation preventing pneumoconiosis, can take following several method: 1) technological innovation, innovation production equipment, eliminating dirt source is the fundamental way eliminating dust harzard; 2) wet operation, mine wet drilling, underground transportation spray sprinkler etc. are the main paties eliminating dust; 3) airtight, exhausting, dedusting.To the place can not taking wet operation, adopt Closed suction dedusting way, prevent dust from flying; 4) individual protection.Under some special operation environment, dirt source cannot be eliminated, wet operation poor effect, and operation can not take the methods such as Closed suction dedusting to prevent dust, then need to wear dust-proof protector to operator, as anti-dust respirator etc.
In respiratory safety device, be most widely used with anti-dust respirator, but the mouth mask on existing market, most based on common mouth mask, because mine operation environment is special, workman is in underground work engineering, the common mouth mask worn for a long time, feels unsmooth breath under high-strength working condition; Face is close to by mouth mask, and breathe damp and hot, facial perception is uncomfortable; Wear time screech owl portion pain; Frenulum system hangs on ear, and insecure instability, easily drops; And common mouth mask dust-proof effect is undesirable, long working, dust can invade human body through mouth mask.Respirator protection effect is good, but its weight is comparatively large, is mainly used in toxic and harmful and dust work environment, and major part uses among emergency management and rescue process, and its price is higher.These are all the factors causing pneumoconiosis to produce.
