Description

Duct type long tube respiratory system

Technical field

The utility model belongs to ore deposit production safety device, the duct type long tube respiratory system that the closed driving face in particularly a kind of colliery uses.

Background technology

" Safety first, precaution crucial " is the basic principle that China's development of coal is produced.With " one through three prevention " is the safety of coal mines technology of core, has brought into play important function to ensureing Safety of Coal Mine Production recent decades, and in quite long period from now on, will play a significant role.

From the angle of scientific technological advance rule, coal production develops the safety technics requirement, is to be gone to satisfy by the function that the safety technics structure is determined.When the coal production development had proposed new demand to safety technics, safety technics generally was to update in original structural framing, improved the unit function.For example, along with the raising of face per unit area yield is adopted in production development, gas emission constantly increases, and adopts the face wind supply quantity from early stage not enough 200m ³/ min reaches 2000m by now ³/ min; Work plane advances, return airway becomes the 3-4 bar by original 2; Also adopted the comprehensive preventive health measures such as gas drainage system of " close boring, height are taken out lane, big pipeline ", the function of safety technics structure is fully played.But each safety technics that " one through three prevention " contained all has its corresponding, the certain sphere of action and the function limit.When society constantly increases the demand of coal, when having proposed to increase substantially the requiring of safety technics, the approaching or state that reaches capacity of the function of original safety technics, continue to improve, improve powerless in the frame construction of original technology, this has just caused the sharp contradiction of coal production with safety.National security Supervisory Bureau emphasizes to implement the 12 word policies of " take out afterwards earlier and adopt; monitoring; with the wind fixed output quota " again and again, just annotated material facts: there are many collieries in country even comprise that the safety technics function in the state-owned big ore deposit of part has been in ultimate limit state, to taking precautions against the not assurance of ten minutes of serious accident.22 above accidents of once dead hundred people take place in the colliery since the establishment of the nation, and wherein 20 is gas accident.In the serious accident more than once dead 10 people of colliery generation in 2005, gas accident has accounted for 70.7%.Administering the gas disaster, taking precautions against gas accident is the most important thing of safety of coal mines and national safety in production.Can estimate in the near future, when mine production to deep development, single face output improve again, when gas emission increases again, permanently effective conventional security technology of serving coal system still will continue to adopt the new contradiction that strengthens air quantity, improves the way reply production development of extraction ability and pumping volume.And it can be asserted that:, also major accidents such as gas explosion, coal-dust explosion, mine fire can take place from now on along this technology road.

At present both at home and abroad existing expert and the scientific and technical personnel research of setting up the project, and the imagination of construction " essential safe type mine " has been proposed, this mine really has the gas explosion of stopping, coal-dust explosion, stops the function of mine fire.So-called essential safe type mine is that the import and export with mine all is closed, and isolates with surface air, and institute has living space and fills with inert gas in the mine, and the personnel in the pit wears the optional equipment of keeping breathing as Qinghai-Tibet Railway construction person---the breather operation.Because the content of oxygen is low, can successfully stop gas explosion, pyrophoricity accident, stops serious accidents such as down-hole spontaneous fire, exogenous fire, coal-dust explosion.Increase and to replace the inert gas (N of injection in advance with the gas total amount of gushing out ₂), at this moment gas can be extracted utilization out.The long tube breather that now has been widely used in shipbuilding, chemical industry, its plenum system have two kinds: i.e. blast type long tube breather and vehicular long tube breather.The former be with air pump with fresh air to staff's mask air feed with wind point; The latter be by vehicle-mounted compressed air bottle through appendix to staff's mask air feed, vehicle-mounted compressed air bottle can move with the staff.The former can realize continuous air feed, but is subjected to the distance limit of supplying gas; The latter is compressed the restriction of air bottle capacity, can only use simultaneously for 2-4 people, and running hours, need standby a plurality of gas cylinders.Obviously, these two kinds of long tube breathers can not satisfy that the driving face in coal mine personnel are many, the working time is long, the requirement of the distance of supplying gas.

Summary of the invention

The objective of the invention is to overcome above-mentioned technical deficiency, a kind of distance of supplying gas is provided, adapt to the duct type long tube respiratory system that the staff is many, the working time is long.

The technical scheme that the utility model technical solution problem adopts is: a kind of duct type long tube respiratory system of being made up of motor, oil free type air compressor, flexible pipe and tube cover, be characterized in adorning an air staticizer at the air compressor air intake vent, air outlet is adorned an integrated sealing discharger, integrated sealing discharger outlet is connected with the pipeline that two ends are fixed with flange, pipeline passes enclosing wall, adorns a plurality of hose couplings and control valve between enclosing wall and driving face.

The beneficial effects of the utility model are: this system provides scientific method for construction of coal mine essential safe type mine; Use at closed driving face, effectively ensure workers'health and safety, stop the generation of anthracosis; Stop serious accidents such as gas explosion, spontaneous fire, exogenous fire, coal-dust explosion; Can realize that the long distance driving in single lane reduces the tunnel significantly and drives engineering, improve the tunnelling rate, reduce the production management link, reduce the coal production cost.
