Embodiment 1
A kind of ventilation device for preventing coal mine gas from transfiniting, including be vertically arranged fixed plate 1, be vertically arranged to fixed plate
Dedusting air inlet on 1,4 structure of dedusting bend pipe for being connected to 1 right side of fixed plate and positioned vertical are in 4 structure of dedusting bend pipe
On connection air duct 2 and the horizontal blower 3 being socketed on connection air duct 2,
4 structure of dedusting bend pipe includes the bend pipe 4 in 1 right wall of horizontal connection fixed plate, is flush-mounted in 4 inside corners of bend pipe
The first filter screen 5 in upper vertical walls, inclination are installed on the identical spray head 6 of several structures in 4 inner vertical walls face of bend pipe, peace
Loaded on the spiral demarcation plate 7 on 4 horizontal interior walls face of bend pipe,
Several described spray heads 6 are located at 5 top of the first filter screen, and 7 central horizontal of spiral demarcation plate is equipped with mandrel
8, the angle of horizontal plane is identical between several described spray heads 6.
Further, the spray head 6 cleans the first filter screen 5, its long-time is avoided not clean, obstruction ventilation
Road.
Further, the dedusting air inlet includes the cage plate 9 being installed vertically on 1 left wall face of fixed plate, flush-mounted in set
The second filter screen 10 and connection sleeve plate 9 and the bolt of fixed plate 1 11 in plate 9.
Further, as shown in figure 4, the cage plate 9 can be dismantled by bolt 11, the second filter screen 10 can be washed
Brush.
Further, as shown in Figure 1, the connection air duct 2 is installed vertically in 4 vertical end of bend pipe, and pass through between the two
Ring flange 12 connects.
Further, the ring flange 12 increases connection air-tightness, prevents dust from entering.
Further, the screwed separation panels outer diameter is identical as casing inner diameter, and its mandrel 8 is cylindrical structure.
Further, diversion trench 13 is offered on horizontal lower wall face in the bend pipe 4.
Further, the diversion trench 13 is convenient for the dirty water discharge after cleaning.
Further, as shown in Figure 1, several described spray heads 6 are specially the identical spray head 6 of three pairs of structures, and between it
Angle is 60 °.
Further, the 4 bent angle degree of bend pipe is 90 °.
It opens, the air in mine is extracted, by installing fixed plate 1 in use, controlling blower 3 by controller
On mine inner wall, rear bridge piece 4 passes through the fixed cage plate 9 of bolt 11, set as the outlet of mine air on front face
The second filter screen 10 among plate 9 carries out coarse filtration to air, and mine air is entered by bend pipe 4, can encounter spiral demarcation plate 7,
After spiral demarcation plate 7 spiral-shaped is so that air enters, since the wall attachment effect of air-flow enters bend pipe along spiral demarcation plate 7
4 vertical pipe section, when air is advanced in spiral demarcation plate 7, solid particulate matter can be attached to or strike spiral demarcation plate 7
