Abstract
The utility model discloses a zero resistance rotary type ventilation air methane collecting device which is rotatable and arranged beside a ventilator diffusion tower of a mine. When collection of ventilation air methane is needed, the zero resistance rotary type ventilation air methane collecting device is controlled to rotate to an air outlet of the ventilator diffusion tower of the mine to collect the ventilation air methane. When the collection of the ventilation air methane is not needed, the zero resistance rotary type ventilation air methane collecting device is controlled to rotate to leave the air outlet of the ventilator diffusion tower of the mine. The zero resistance rotary type ventilation air methane collecting device rotates to the air outlet of the ventilator diffusion tower of the mine only when the collection of the ventilation air methane is needed, and when the collection of the ventilation air methane is not needed, the zero resistance rotary type ventilation air methane collecting device leaves the air outlet of the ventilator diffusion tower of the mine to achieve zero resistance to air exhaust of the mine.

Background technology
" ventilation air gas " claims " colliery wind gas-removing " again, and nail alkane concentration is lower than 0.75% coal mine gas, because methane content is low and lack and effectively to utilize mode and directly enter in the atmosphere.The gas emission in China's coal-mine every year has 80%～90% approximately, discharges in the mine ventilation mode.According to the interrelated data statistics, the methane content that entered in the atmosphere by weary wind in 2008 has reached 16,100,000,000 m
3Be equivalent to the displacement of transferring natural gas from the west to the east 1 year.Other there are some researches show that the methane greenhouse effect are about 21 times of carbon dioxide, and the damage capability of atmospheric ozone layer is about 7 times of carbon dioxide, and is extremely strong to environmental destruction.Therefore, effective collection and utilize ventilation air gas to have energy-conservation and environmental protection double meaning.
Along with the progress and the development of science and technology, the research of ventilation air gas utilization has been had very big progress, present stage the technology of utilizing to ventilation air gas be mainly hot counter flow oxidation technology, methods such as mixed combustion, enrichment method are also arranged in addition.But the prerequisite of these technology all relates to the collection of gas.
Zero resistance rotary type ventilation air gas gathering-device or system are stationary structure at present, as patent documentation disclosed " the non-airtight linkage of a kind of weary wind " (201120230973.8), " coal master wants the ventilator diffuser top to collect the method and apparatus of ventilation air gas " (20110234290.2), " a kind of collection method of coal mine wind-lack gas and device " (201110234289.X), this class zero resistance rotary type ventilation air gas gathering-device has all produced certain influence to the air draft of mine, has potential safety hazard; The structural disadvantages of constant zero resistance rotary type ventilation air gas gathering-device has: at first, when follow-up equipment does not need ventilation air gas, the ventilation air gas collecting hood still is arranged in the retention tower outlet, or exist physics to contact with retention tower, this will certainly exert an influence to the mine for air exhaustion blower fan, influence the normal air draft of mine, produce potential safety hazard; Secondly, at two retention towers that replace air draft, need to build two ventilation air gas collecting hoods correspondences and collect, increase corresponding collection pipeline and control appliance simultaneously, equipment economy input is high.
Therefore, need improve zero resistance rotary type ventilation air gas gathering-device of the prior art, to solve the defective that it exists.
The utility model content
In view of this, the purpose of this utility model provides a kind of zero resistance rotary type ventilation air gas gathering-device, it can satisfy the collection requirement of weary wind, can can solve the defective that existing fixed zero resistance rotary type ventilation air gas gathering-device exists to the not influence of normal operative condition of mine main exhaust fan again.
The utility model zero resistance rotary type ventilation air gas gathering-device, collecting hood, the collecting pipe that is connected with collecting hood that comprises support, cooperates with two adjacent mine ventilation fan retention tower air outlets, be arranged on motor and the reducer that is connected with rotor on the support, the distance at the output shaft to two of a described reducer mine ventilation machine retention tower air outlet center equates, the outlet air end of described collecting pipe is connected with the center swivel joint coaxial with the reducer output shaft center, and described collecting pipe is fixed on the reducer output shaft.
Further, also be set with the circular orbit coaxial with reducer output shaft on the described support, described collecting pipe also is provided with the carriage that is slidingly matched with the circular orbit single-degree-of-freedom;
Further, also comprise the controller of controlling motor action.
The beneficial effects of the utility model:
1, the utility model zero resistance rotary type ventilation air gas gathering-device, zero resistance rotary type ventilation air gas gathering-device just is transferred to mine ventilation machine retention tower air-out oral area when needing to collect ventilation air gas; When not needing to collect ventilation air gas, zero resistance rotary type ventilation air gas gathering-device leaves mine ventilation machine retention tower air outlet, has realized mine for air exhaustion zero drag effects.
2. the utility model zero resistance rotary type ventilation air gas gathering-device can reduce the equipment cost input: when two retention towers of the using and the reserved, conventional fixed formula zero resistance rotary type ventilation air gas gathering-device needs two covers, and the utility model zero resistance rotary type ventilation air gas gathering-device only needs a cover.
3. the utility model zero resistance rotary type ventilation air gas gathering-device safety is good: do not collecting under the ventilation air gas situation, zero resistance rotary type ventilation air gas gathering-device leaves mine ventilation machine retention tower air outlet, make weary wind utilize system and colliery diffusion system to separate fully, can guarantee the normal operative condition of coal mine air draft, eliminate safe hidden trouble fully.
4. the utility model zero resistance rotary type ventilation air gas gathering-device compact conformation, flexible movements, compliance is good, and the ventilation air gas that can be widely used in the colliery retention tower is collected.
Description of drawings
Fig. 1 is the structural representation of the utility model zero resistance rotary type ventilation air gas gathering-device.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, present embodiment zero resistance rotary type ventilation air gas gathering-device, collecting hood 3, the collecting pipe 4 that is connected with collecting hood 3 that comprises support 1, cooperates with two adjacent mine ventilation fan retention tower 2 air outlets, be arranged on motor 5 and the reducer 6 that is connected with rotor on the support 1, the distance at the output shaft to two of described reducer 6 mine ventilation machine retention tower 2 an air outlet center equates, the outlet air end of described collecting pipe 4 is connected with center and the coaxial swivel joint 7 in reducer 6 output shaft centers, and described collecting pipe 4 is fixed on the output shaft of reducer 6.
