Description
Technical field
The present invention relates to coal mine roadway ventilating dust-removing technology field, a kind of control dirt dress with annular side air channel
Put.
Background technology
A large amount of dust that work surface can produce during mining, dust suction is carried out clean by dedusting air duct by cleaner unit
Change processes.Without dust control device, air duct distinguished and admirable meeting in tunnel is all flowed out from air outlet and is directly blown onto work surface, by work
The dust in face dispels backward, makes cleaner unit all suctions of work surface dust not processed, affects the efficiency of dust collection of work surface.
Therefore, away from work surface certain distance, one dust control device is installed at tunnel air feed air duct, used by existing coal mine roadway
Dust control device, when dust recycling is controlled by needs, air door is closed, the most distinguished and the most admirable from the blowout of dust control device crosswind mouth, forms wind
Wall stops that dust spreads backward, it is ensured that dust enters cleaner.When normally ventilating, door opening, also need to artificial simultaneously
Dust control device crosswind mouth is blocked, prevents distinguished and admirable from the outflow of dust control device crosswind mouth, the most distinguished and the most admirable from the blowout of termination air duct mouth, protect
Card air supply of working face amount.
Manually dust control device crosswind mouth is blocked, increase operating personnel's amount of labour, affect operating personnel and operate enthusiasm；With
Time, the dust control device many employings steel used by existing coal mine roadway, heavy mobile inconvenience.
Summary of the invention
The technical problem to be solved is: the most effectively alleviates air duct weight, and automatically controls work surface confession
Wind.
The technical solution adopted in the present invention is: a kind of dust control device with annular side air channel, the left end of main air duct
Having left air duct to connect end circle, the right-hand member of main air duct has right air duct to connect end circle, and left air duct connects end circle and connects tunnel air duct, right
Air duct connects end circle and connects air door, grooved hole on main air duct sidewall, and slotted eye connects annular side wind pipeline, and air door is by door frame, peace
It is contained in the round door within door frame to be connected with round door rotating shaft and be arranged on handle outside door frame, be arranged on turning of door frame side
Moving frame, for connect rotating turret and handle latch composition, have hole, multiple location above rotating turret camber, middle handle has one
Individual connecting hole, according to the size of Air Quantity Required, is inserted in latch on connecting hole and hole, a location so that air door is in different
Opening degree, when fully opening air door, wind directly flows through from air door, within annular side wind pipeline wind formed pressure relatively
Little, wind all flows out from the main air outlet of air door, when not exclusively opening air door or thoroughly close air door, in annular side wind pipeline
The pressure that the wind in portion is formed is relatively big, and wind is flowed out by annular side wind pipeline.
As a kind of optimal way: main air duct is fixed by transverse steel by multiple steel rings, multiple steel ring passes through air duct
Cloth connects into a cylinder, by using steel ring as joint face, to decrease the weight of main air duct as skeleton, air duct fabric.
As a kind of optimal way: one semicircle steel ring of position welding of each steel ring corresponding slot, semicircle steel ring passes through
Air duct fabric connects into the axial seal along cylinder of semicircular cylinder, semicircular cylinder and cylinder, semicircular cylinder and the cylinder circumference along cylinder
One end open one end seals, and semicircular cylinder and cylinder are bonded annular side wind pipeline.
As a kind of optimal way: semicircular cylinder and cylinder are along the circumferential openings position of cylinder, to opening from semicircular cylinder
One section of air duct fabric is extended in position.
As a kind of optimal way: steel ring is 5.
The invention has the beneficial effects as follows: when door opening normally ventilates, due to the effect of annular side wind pipeline, entirely
Portion is distinguished and admirable to be blown out by air door, flows out from annular side wind pipeline without distinguished and admirable, it is not necessary to manually blocked by dust control device crosswind mouth, solves
Existing dust control device needs manually to be blocked by dust control device crosswind mouth, and the problem of complex operation improves work efficiency；Simultaneously
Air duct fabric design is used to compare existing air duct weight saving more than 80%.

Detailed description of the invention
As Figure 1-Figure 5,5 steel rings are fixed by transverse steel, cover in outside by air duct fabric and form a tubular
Main air duct, the left end of main air duct have left air duct connect end circle, the right-hand member of main air duct have right air duct connect end circle, Zuo Feng
Cylinder connects end circle and connects tunnel air duct, and right air duct connects end circle and connects air door, grooved hole on main air duct sidewall, and slotted eye connects ring
Shape crosswind pipeline, one semicircle steel ring of position welding of each steel ring corresponding slot, semicircle steel ring connects into half by air duct fabric
Cylinder, semicircular cylinder and cylinder are along the axial seal of cylinder, and semicircular cylinder and cylinder are close along circumferential one end open one end of cylinder
Envelope, slotted eye is in one end of circumferential seal, and semicircular cylinder and cylinder are bonded annular side wind pipeline so that from slotted eye wind out
Can must be flowed out by annular side wind pipeline.Annular side wind pipeline is along the circumferential openings position of cylinder, from semicircular cylinder
One section of air duct fabric is extended, the little situation of air pressure that air duct fabric is formed at the wind of annular side wind pipeline to aperture position
Under, cover annular crosswind pipeline air outlet under gravity, in the case of the air pressure of wind formation is relatively big, blown open.
Air door by door frame, be arranged on the round door within door frame and be connected with round door rotating shaft and be arranged on handle outside door frame, be arranged on
The rotating turret of door frame side, for connecting the latch composition of rotating turret and handle, have hole, multiple location above rotating turret camber,
Middle handle has a connecting hole, and latch is inserted on connecting hole and hole, a location.
When completely without control dirt, normally ventilating, distinguished and admirable from the entrance of tunnel air duct, turning handle is by door opening
To maximum, distinguished and admirable directly discharge from main air outlet by air door, owing to annular surveys wind pipeline resistance relatively greatly, and due to gravity work
Can automatically fall to covering on the air outlet (semicircle of annular side wind pipeline with extending one section of air duct fabric to aperture position on semicircular cylinder
Cylinder and cylinder are along the circumferential openings position of cylinder), increase the resistance of air-out, the insufficient pressure of wind is with from annular side wind pipeline
Air outlet flow out, most wind is discharged from main air outlet, it is achieved tunnel normally ventilates.
When needs control dirt, distinguished and admirable from the entrance of tunnel air duct, air door is closed by turning handle, distinguished and admirable from slotted eye entrance annular
Crosswind pipeline, the air pressure that wind is formed is relatively big, distinguished and admirable all from annular side wind pipeline opening (annular side wind pipeline air outlet)
Flow out, form brattice, stop that dust spreads backward, play tunnel control dirt effect.
