Description
Technical field
The utility model relates to excavation face in coal mine ventilation equipment, particularly relates to air duct.
Background technology
In excavation face in coal mine development machine tunneling process, because coal petrography fragmentation can produce a large amount of dust simultaneously, it is the major safety risks problem that Safety of Coal Mine Production exists always, workman and equipment are all in pollute environment in, both the health of workman had been compromised, also easily cause coal-dust explosion, threaten the safety in production of mine.
Current most of fully mechanized workface is furnished with dedusting fan, employs air duct again on the basis of the inside and outside spraying of development machine.Air duct is a kind of wall attachment effect utilizing air-flow, when starting coal cutting, straight in air duct is erected to air door, make the distinguished and admirable rotary airflow changed into along wall of axis of former forced air duct supply tunneling working face, and blow to the perisporium in tunnel and whole drift section with certain rotary speed, and constantly advance to tunneling working face, suck the acting in conjunction of dust-contained airflow generation axial velocity at deduster under, just the zigzag shape air-flow with higher functionality is formed, set up in the front of development machine driver and stop the air screen of dust to external diffusion, the dust produced when blocking development machine work, make it carry out purifying through dust shield suction deduster and do not outflow, thus improve the dust-collecting efficiency of tunneling working face, when do not tunnel only carry out other operation time, straight in air duct is pulled down to air door, make freshly distinguished and admirablely directly to enter work plane, return to normal ventilation, principle is shown in Fig. 1.
During the start of work plane dust removal machine, use air duct, there is following problem: 1, distinguished and admirable by outer and in, gas of meeting head on, dust concentration height is not easily discharged by distinguished and admirable extruding; 2, air duct air quantity is unadjustable, during the change of dedusting fan suction air volume, easily forms circulated air, there are major safety risks.
Summary of the invention
In order to solve above-mentioned air duct distinguished and admirable unadjustable, not there is ambulant problem, the utility model carries bidirectional adjuster.
A kind of air duct bidirectional adjuster, it is characterized in that, it is the three-way air duct that a joint and air duct diameter match, and is serially connected on air duct, and is in the position near development machine rear by the two ends outlet of three-way air duct; The top of described three-way air duct is provided with side direction and divides wind to export, the direction that side direction divides wind to export is the tangential direction of three-way air duct section, divide wind to export in side direction and be provided with adjustable side direction air door, side direction air door is used for distinguished and admirable for the part air duct side direction that is assigned as to divide distinguished and admirable, and regulates a point air force; Be provided with adjustable straight to air door in the air-out side neck of described three-way air duct, by the straight effect to air door, ensure point air quantity of side direction air door.
In order to reduce the dust concentration of three-way air duct side direction air door, near side direction air door, atomization mechanism is installed.
Operating principle of the present utility model and good effect are, during dust removal machine start, regulate side direction air door and the straight aperture to air door, ensure point air quantity that side direction divides wind to export, the distinguished and admirable air quantity of part is directly discharged from development machine rear, reduce the extruding of distinguished and admirable gas to meeting head on, dust, gas, dust are discharged from dust removal machine smoothly; During the change of dedusting fan suction air volume, by regulating air duct air quantity, avoid easily forming circulated air; Structure is simple, and lightweight material can be adopted to make and produce, hanging is installed simple and easy, easy to operate.
Provide preferred embodiment below and be described with reference to the accompanying drawings.

Marginal data, 1-three-way air duct, 2-side direction divides wind to export, 3-side direction air door, and 4-is directly to air door, and 5-meets head on, and 6-is distinguished and admirable, 7-dust removal machine, 8-development machine, 9-air duct.
Detailed description of the invention
As Figure 1-4, a kind of air duct bidirectional adjuster, it is the three-way air duct 1 that a joint and air duct diameter match, and is serially connected on air duct 9, and is in the position near development machine 8 rear by the two ends outlet of three-way air duct 1; The top of described three-way air duct 1 is provided with side direction and divides wind to export 2, the direction that side direction divides wind to export 2 is the tangential direction (as Fig. 2) of three-way air duct 1 section, divide wind to export on 2 in side direction and be provided with adjustable side direction air door 3, side direction air door 3 for dividing distinguished and admirable by distinguished and admirable for the part air duct side direction that is assigned as, and regulates a point air force; Be provided with adjustable straight to air door 4 in the air-out side neck of described three-way air duct 1, by the straight effect to air door 4, ensure point air quantity of side direction air door.
In order to reduce the dust concentration of three-way air duct 4 side direction air door 2, atomization mechanism 10 is installed near side direction air door 2.
During development machine 8 works and dust removal machine 7 is started shooting, divide wind to export 2 by side direction, the distinguished and admirable air quantity of part is directly discharged from development machine 8 rear, and reduce distinguished and admirable 6 to the gas of 5 of meeting head on, the extruding of dust, gas, dust are discharged from dust removal machine smoothly; During the change of dedusting fan 7 suction air volume, by regulating air duct air quantity, avoid easily forming circulated air (as Fig. 3); Development machine stops, when carrying out other work such as supporting, work plane dust removal machine 7 can cut out, and now closes side direction air door 3, and standard-sized sheet, directly to air door 4,5 provides new wind distinguished and admirable 6 (as Fig. 4) to meeting head on.
