Abstract
The utility model discloses a mine ventilation air-increasing device. An air inlet connecting airway is built between an air inlet airway and a return airway, an auxiliary ventilating chamber is formed in the connecting position of the air inlet connecting airway and the return airway in an expanding mode, a return circular airway is arranged on two sides of the auxiliary ventilating chamber, the return connecting airway is built between the return circular airway and the auxiliary ventilating chamber, and air doors are arranged in the return connecting airway and the return circular airway, namely, a first air door and a second air door. An auxiliary fan is arranged in the auxiliary ventilating chamber, the air inlet of the auxiliary fan faces the air inlet connecting airway, and the air outlet of the auxiliary fan faces the return connecting airway. According to the mine ventilating air-increasing device, only a small number of roadways need to be developed under a shaft, the auxiliary fan is simply added, a large number of ventilating roadways are not needed, the cross sections of the roadways do not need to be added, developing quantities are greatly reduced, investment is reduced, and a construction period is shortened.
Description
Technical field
The utility model relates to the mine ventilation device.
Background technology
In coal mining, underground ventilating must not lack.Normally set up ventilating shaft on the border, mining area, ventilation fan is installed, air intake lane and return airway are established in the down-hole.The quantity of air intake lane and return airway and section size have determined the size of ventilation.Along with the increase of yield, down-hole demand air quantity is increasing, is generally quantity and the section that increases air intake lane and return airway, increases air quantity.This technology developing amount is large, and the construction period is long, and cost is high.
Summary of the invention
The purpose of this utility model is to overcome the cloth deficiency of prior art, provides a kind of mine ventilation to increase wind apparatus.
The technical scheme that the utility model is taked is:
A kind of mine ventilation increases wind apparatus, comprise air intake lane and return airway, it is characterized in that, set up an air intake connection roadway between air intake lane and return airway, extend into the secondary ventilation chamber in air intake connection roadway and the junction of return airway, a return air is set up around the lane in the both sides of secondary ventilation chamber, and return air is set up the return air connection roadway again and between the secondary ventilation chamber around the lane, return air connection roadway and return air are equipped with air door in the lane, be respectively the first air door and the second air door; In the secondary ventilation chamber, accessory fan is installed, the air intake of accessory fan is facing to the air intake connection roadway, and the air outlet of accessory fan is facing to the return air connection roadway.
When ventilation increases wind, open the first air door, close the second air door, increase wind for the down-hole after the unlatching accessory fan; During overhaul of the equipments, stop accessory fan, close the first air door, open the second air door, make return air open-minded around the lane, guarantee normally to ventilate.
Good effect of the present utility model is, only in a small amount of tunnel of developing, down-hole and set up accessory fan and get final product, need not open up a large amount of airways and increase drift section, and the developing amount greatly reduces, and saves investment and minimizing construction period.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Marginal data, 1 air intake lane, the 2-return airway, 3-air intake connection roadway, 4-secondary ventilation chamber, 5-return air is around the lane, 6-return air connection roadway, 7-the first air door, 8-the second air door, 9-accessory fan.
The specific embodiment
As shown in Figure 1, a kind of mine ventilation increases wind apparatus, comprise air intake lane 1 and return airway 2, set up an air intake connection roadway 3 between air intake lane 1 and return airway 2, extend into secondary ventilation chamber 4 in air intake connection roadway 3 and the junction of return airway 2, a return air is set up around the lane 5 in the both sides of secondary ventilation chamber 4, and return air is set up return air connection roadway 6 again and between secondary ventilation chamber 4 around lane 5, be provided with the first air door 7 in return air connection roadway 6, be provided with the second air door 8 at return air in lane 5; Accessory fan 9 is installed in secondary ventilation chamber 4, and the air intake of accessory fan 9 is facing to air intake connection roadway 3, and the air outlet of accessory fan 9 is facing to return air connection roadway 6.
