Abstract
A mobile dustproof water curtain is composed of an annular water pipe (1) and a sheer (2). The annular water pipe (1) is communicated with a penstock and a compressed air pipe, and the annular water pipe (1) is provided with multiple nozzles. The mobile dustproof water curtain is characterized in that the sheer (2) is fixed on the annular water pipe (1) which is detachably installed on a rubber belt conveyor H-shaped frame, and the annular water pipe (1) and the sheer (2) fixed on the annular water pipe (1) can move forwards continuously according to working surface propulsion. Compared with the prior art, by means of the mobile dustproof water curtain, mine dust which is already generated and suspended in an air current can be effectively inhibited and eliminated, a fundamental method for preventing and controlling mine dust hazards is achieved, and a dustproof facility for scientifically and reasonably improving the driving working face is obtained. Meanwhile, a mist spray is installed at a transfer point, a mobile water curtain is installed on the lee side of pulp shooting machine operation, personal protective equipment of workers is strengthened, effective dustproof measures are adopted, and the comprehensive dustproof effect of the driving work face can be very effectively achieved.
Description
Technical field
The present invention relates to a kind of dust arrester, especially a kind of portable dustproof water screen.
Background technology
It is known that driving face one of topmost dust point when being colliery capital construction.Along with mechanical drivage
Improving constantly of degree, continuing to increase of drift section, use single fall (removing) dirt technology and measure increasingly can not meet
Safety and the needs produced.From the point of view of current condition of construction, each production link produce mine dust ratio substantially: during driving produce
Mine dust is total amount 20%～75%, shotcrete setting dust-producing amount accounts for 10%～15%；Haulage drift dust-producing amount account for 5%～
10%, each setting increases the most therewith with the raising of mechanization degree, the growing amount of mine dust.One to two is arranged at work surface rear
The water curtain that road moves with work surface, reduces dust concentration, increases the safety coefficient of construction period, creates safely for worker, totally
Working environment.At present, the dustproof water curtain in mine is fixed, along with the extension of mine development end, needs constantly to increase
Reach refitting after adding the quantity of dustproof water curtain or being removed by dustproof water curtain below, wastes time and energy, waste material is taken a lot of work.Therefore, design
A kind of portable dustproof water screen, is to be presently required to solve the technical problem that.
Summary of the invention
The technical problem to be solved is to provide a kind of portable dustproof water screen.
The present invention solves the technical scheme of its technical problem:
Portable dustproof water screen, is made up of annular conduit and yarn curtain, and annular conduit connects with pressure water pipe and pressure ventilation pipe, in annular
Being provided with some nozzles on water pipe, yarn curtain is fixed on annular conduit, and annular conduit is detachably arranged in rubber conveyer " H "
On frame, annular conduit and the yarn curtain being fixed on annular conduit constantly can move forward according to the advance of the face.
The movable type constituted as a preferred embodiment of the present invention, annular conduit and the yarn curtain being fixed on annular conduit
Dustproof water screen distance work surface 150 50m.
For the dust removing effects in the whole tunnel of guarantee, portable dustproof water screen has 4 roads, removes distance work surface 150 meter 50
Outside meter Yi Dao, distance work surface 300 meters, 600 meters with return air inlet 50 meters at also respectively together with.
As a preferred embodiment of the present invention, the material of described annular conduit is seamless steel pipe, and annular conduit is
Multistage seamless steel pipe is formed by connecting by steel tube connection head.
The know-why of the present invention:
By press water by aerosol apparatus (also known as nozzle), under the effect of pressure wind impact, atomization of water current is made to become trickle water droplet to spray
Penetrating in air, in mist body sphere of action, after swiftly flowing water droplet and floating dust making contact, grit is wet, at gravity
Effect is sunk；Swiftly flowing mist body is moistening sinking in dust laden air about is attracted to mist body；The dirt that will have sunk
The moistening bonding of grain, is allowed to be difficult to fly upward finally catch on Dust collecting net, and the layout of aerosol apparatus should be covered with drift section to the greatest extent with water curtain
May be principle near dirt source.At top, work surface 150--50m tunnel, install one move water curtain, according to the advance of the face
Constantly reach.Away from work surface 300m, 600m each with at return air inlet 50 meters together with.
The using method of the present invention: be arranged on the semi-circular sprayer unit on rubber conveyer " H " frame, install several spray
Day with fog is also connected to form wind power ganged spraying with pressure wind.The arrangement of nozzle and quantity, Nozzle Parameter carry out type selecting, these
All the closest with the relation of dust-laying effect.Water yield during water supply and the size of air quantity, it should based on wind, water is auxiliary, ability
Reach intended dust-laying effect to be so also beneficial to reduce the series of problems that work surface brings due to construction water.Use optimal
Airflow velocity for eliminating dust and rational aeration technology, be typically advisable between 0.5-3m/s.It is with water and to catch dirt that tunneling boring may move water curtain
Net drops, by being suspended in mine dust in air, the technical measures gone out.Owing to this mine bottom plate is based on mud stone, in order to reduce base plate argillization,
Harden installing before and after water curtain base plate at 5m, with tamper-proof base plate, affect haulage vehicle and pass through.
Compared with prior art, the present invention can effectively suppress and eliminate produce and be suspended in distinguished and admirable in mine dust,
It is the basic method of preventing and treating mine dust harm, is also a kind of scientific and reasonable dustproof facilities improving driving face.Meanwhile, turning
Loading point installs spraying, installs the most removable water curtain at pulp shooting machine operation downwind side, strengthens the personal protection apparatus of workman, take
Effective dust prevention, the effect of the very effective synthesis dust prevention playing driving face of energy, concrete has the advantage that
1., according to the character of mine dust, in dust is suspended in air, when reaching the highest concentration, dust has bigger surface area
Compared with cake mass, dust activeness is strong, along with distinguished and admirable by purification water curtain time.On water curtain, there is not secondary dirty in absorption
Dye, serves the effect of depositing dust；
2. using existing installation i.e. conveyer " H " frame, and do not affect vehicle pass-through and be easy to again mobile, down-hole uses flexibly
Convenient, stress is more scientific, and safety is more preferable；
3. it is designed to wind power ganged, changes and conventional only use water depositing dust, solve base plate argillization below water curtain, affect personnel
And vehicle pass-through, this device utilizes the pressure of pressure wind, and the higher dust-laying effect of the degree that makes water fogging becomes apparent from, and water requirement reduces.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
