Description
Technical field
The present invention relates in terms of coal mining, fully-mechanized mining working keeps out the wind field, is specially a kind of to press air door defeated across adhesive tape
Send machine totally-enclosed abat-vent, kept out the wind suitable for coal boosting fully-mechanized mining working air door.
Background technology
The distinguished and admirable method of operation of coal mine fully-mechanized mining boosting working face, it is by the booster fan boosting installed in chamber, Ran Houjing
Air intake lane, Gu Tang, finally by return airway return air.Need to ensure wind using booster fan and ventilation equipment during distinguished and admirable operation
Stream is stable, air quantity is sufficient, and perfect condition is air intake lane, Gu Tang, return airway one enclosed construction of composition, but due to fully-mechanized mining working
Needing to export coal using adhesive tape conveyor, it is necessary to the haul passage of reserved adhesive tape conveyor so that coal is exported, this
Sample will cause whole booster system air leakage phenomena to be present.In addition, rubber conveyer is transported under two kinds of different operating modes of heavy duty and zero load
Expect that the cross-sectional area of passage is also corresponding different, this will cause working face distinguished and admirable also unstable.Therefore one kind is needed at windbreak,
No matter can be kept out the wind in the case of adhesive tape conveyor zero load or heavy duty, make coal mine fully-mechanized mining working is distinguished and admirable to keep stable gear
Wind apparatus.
The content of the invention
The present invention is leaked out to solve coal mine fully-mechanized mining boosting working face, distinguished and admirable unstable phenomenon, there is provided one kind is being kept off
Haul passage at brattice intersects the applicable pressure air door of section with rubber conveyer across the totally-enclosed abat-vent of rubber conveyer.
The present invention is achieved by the following technical solution：It is a kind of to press air door across the totally-enclosed dress that keeps out the wind of rubber conveyer
Put, include the ladder frame for some equidistant parallels being fixed on rubber conveyer longeron, distinguish on the hypotenuse of each ladder frame both sides
It is arranged with triangular support bracket；Each ladder frame entablature is fixed with front and kept out the wind belt；The triangular support bracket of adjacent trapezoidal frame
Between be provided with side and keep out the wind belt；All ladder frames, which are located at, to be fixed in the trapezoidal totally-enclosed cover on rubber conveyer longeron；
H framves below rubber conveyer longeron are fixed with encapsulated deep bead encapsulated deep bead, upper encapsulated deep bead with and are located at
Between upper and lower transportation rubber belt, encapsulated deep bead is located at below the transportation rubber belt of bottom under described；It is located at air inlet and air outlet respectively
Locate to set side deep bead between the adjacent H framves on the outside of twice brattice.
The present invention is to intersect section with windbreak haul passage in rubber conveyer, in order to eliminate coal mine fully-mechanized mining boosting working face
Leak out, distinguished and admirable unstable phenomenon and the totally-enclosed abat-vent designed, the device can be by rubber conveyer and haul passage
Portion's space-closed is tight, it is particularly possible to closes the distinguished and admirable of air inlet outside twice windbreak and air outlet.In the device, with etc.
Based on the ladder frame being set in parallel in more than rubber conveyer longeron, front is fixed on ladder frame crossbeam and is kept out the wind belt,
Keep out the wind belt, while the overall outer cover on the outside of all ladder frames for fixed setting side between the triangular support bracket of adjacent trapezoidal frame
One trapezoidal totally-enclosed cover；Between the device can realize longeron above twice brattice, to distinguished and admirable from air inlet to air outlet
Stop.Abat-vent below longeron, based on the air inlet and air outlet position on the outside of twice brattice, it is fixed on adhesive tape
On the H framves of conveyer frame, using bottom transportation rubber belt as cut-off rule, it is divided into encapsulated deep bead encapsulated deep bead, upper bag with
Glue deep bead between upper and lower transportation rubber belt, with upper and lower transportation rubber belt coincide by shape, under encapsulated deep bead be located at lower conveying glue
Band lower section；Side deep bead is set on the outside of twice brattice between adjacent H framves, and side deep bead makes the air intake of lower abat-vent
Mouth reduces distinguished and admirable inflow.The device concrete operations are：When wind enters from air inlet, pass through keeping out the wind and belt and keep out the wind machine layer by layer
Structure, make it is distinguished and admirable be gradually reduced, reach totally enclosed effect.
Preferably, the structure of upper encapsulated deep bead is to fix two pieces of belts respectively in one piece of steel plate upper and lower sides to form, lower bag
Glue deep bead is that have one piece of steel plate upside to fix one piece of belt to form, and the belt effect on the two is to make deep bead in conveying glue
With it is unloaded or heavily loaded when have the cushion space of closing.
Preferably, some belt press strips that keep out the wind are arranged between described ladder frame or so hypotenuse in parallel, the belt pressure of keeping out the wind
What the purpose that bar is set was that belt can not be blown when air quantity is very big in order that front is kept out the wind floats up, and ensures its work to keep out the wind
With.
Preferably, the impact idler of top transportation rubber belt is lifted due to being provided with longeron, during in order to prevent adhesive tape load-bearing
Sink, make adhesive tape upper-lower position constant, ensure the following haul channel enclosed of rubber conveyer longeron, in trapezoidal totally-enclosed cover
The impact idler bottom in portion is provided with load-bearing saddle rack, and for saddle rack similar to horse-saddle, it is defeated that load-bearing saddle rack both sides are installed on adhesive tape
Send on machine longeron.
Preferably, air outlet spraying filter wind apparatus, including sprayer and filter are provided with the ladder frame at air outlet
Wind net, settle and filter for coal dust.
The present invention by different wind-blocking mechanisms by the distinguished and admirable control of working face in air channel of keeping out the wind, and make air quantity layer in air channel
Layer weakens, and is finally reached the effect kept out the wind；The application of the covering device not only reduces the input of equipment, while extends working face
Length can be adopted, adds working face layout, improves the reliability of ventilation equipment, has ensured the normal production of working face.Especially
The advantage of the totally-enclosed abat-vent can be embodied from following digital information：
Before installing abat-vent additional, ancient pool pressure difference is adjusted to air-out 1mmH2During O, air intake lane lane pressure difference 92mmH2O, return airway pressure difference
99mmH2O, air intake 720m3/ min, return air 742m3/ min, upper corner O2Concentration 20.5%, 23.6 DEG C of working face temperature, but adhesive tape
Pressure difference is unstable when heavily loaded, air intake lane pressure difference 106m when heavily loaded3/ min, return airway pressure difference 110m3/ min, ancient pool pressure difference air intake
10mmH2O。
After installing abat-vent additional, ancient pool pressure difference is adjusted to air-out 1mmH2During O, air intake lane pressure difference 93mmH2O, return airway pressure difference
102mmH2O, air intake 1120m3/ min, return air 1128m3/ min, upper corner O2Concentration 20.7%, 21.2 DEG C of working face temperature, adhesive tape
Air intake lane pressure difference 95mmH when heavily loaded2O, return airway pressure difference 103mmH2O, ancient pool pressure difference enter 1mmH2O, during than belt zero load more than 1-
2mmH2O, booster system are more stable.
After installing abat-vent additional, inleakage reduces by about 400 m3/min.From above-mentioned data, the abat-vent is installed additional
Afterwards, inleakage is reduced.
