Description
Technical field
The utility model relates to mine refuge technical field of air purification, specifically belongs to a kind of down-hole refuge room pressure wind switch board.
Background technology
In mine operation, in order to the personal safety of safeguard work personnel, need in mine, arrange the temporary shelters such as refuge chamber, self-rescuer chamber, transition station.Once have an accident, staff temporarily can hide and to wait for rescue in these refuges.Because mine is all in very dark underground, main when having an accident is that the staff that will ensure in mine has enough air to sustain life to wait for rescue, so be provided with mine pressure ventilation system in mine for staff to provide air, but limited space in mine, and mine pressure ventilation system comprises a lot of mechanism, put installation step by step and take up room very much, field erected efficiency is low, difficulty is large, construction can be very slow, wastes a lot of time.
Utility model content
For the problems referred to above, the purpose of this utility model there is provided a kind of down-hole refuge room pressure wind switch board, overcome the deficiencies in the prior art, reasonable in design, compact conformation, pipeline connection port connection and reasonable arrangement, installs simple and convenient, substantially reduce the installation difficulty of mine pressure ventilation system, improve installation rate; Air inlet is provided with multistage purification, and the greasy dirt in effective filtering pressure wind, improves air purity high.
The technical solution adopted in the utility model is as follows:
A kind of down-hole refuge room pressure wind switch board, comprise casing, secondary current divider and sound absorber, casing is provided with pressure wind entrance, pressure wind entrance is connected to sound absorber by admission line, described admission line connects secondary current divider, secondary current divider forward air inlet pipeline is connected with hand-operated valve, rear is provided with automatic control valve, air curtain spray tube connector is provided with between secondary current divider and automatic control valve, air curtain spray tube connector extends to outside casing, described muffler outlet is connected to by pipeline gives vent to anger on box, described sound absorber is also connected with reducing valve, described secondary current divider lower end is connected with backflow blow-off pipe, backflow blow-off pipe is provided with ball valve and controls folding.
Described box of giving vent to anger is provided with deduster, reduces deaeration dust degree, improves chamber air quality.
The porous network structure that described deduster is made up of active carbon is formed.
Described casing lower end is provided with roller.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model air inlet is shunted through multistage purification, discharging is exactly the air can breathed for staff, and the blow-off pipe of the greasy dirt filtered out in secondary current divider by bottom is discharged, greasy dirt during effective filtering pressure wind air feed in air, improve air degree of purity, the greasy dirt that blow-off pipe is discharged simultaneously flows into gutter, also ensure that the sanitation of environment of refuge chamber; Gas outlet is connected with noise damper by pipeline, and sound absorber is connected with reducing valve, can regulate pressure size, to reduce noise at any time according to indoor noise situations of surviving in refuge chamber; Pipeline connection port connection and reasonable arrangement, installs simple and convenient, substantially reduces the installation difficulty of mine pressure ventilation system, improves installation rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that the utility model is overlooked.
Detailed description of the invention
See accompanying drawing, a kind of down-hole refuge room pressure wind switch board, comprise casing 1, secondary current divider 2 and sound absorber 3, casing is provided with pressure wind entrance 101, pressure wind entrance 101 is connected to sound absorber 3 by admission line 4, described admission line 4 connects secondary current divider 2, secondary current divider 2 forward air inlet pipeline 4 is connected with hand-operated valve 5, rear is provided with automatic control valve 6, air curtain spray tube connector 7 is provided with between secondary current divider 2 and automatic control valve 6, air curtain spray tube connector 7 extends to outside casing, described sound absorber 3 exports to be connected to by pipeline gives vent to anger on box 8, described sound absorber is also connected with reducing valve 301.Described secondary current divider 2 lower end is connected with backflow blow-off pipe 9, and backflow blow-off pipe is provided with ball valve 10 and controls folding; Described box 8 of giving vent to anger is provided with deduster 801, and the porous network structure that deduster 801 is made up of active carbon is formed, and is provided with release electrostatic line in porous web, deduster reduces deaeration dust degree, improve chamber air quality, described casing 1 lower end is provided with roller 102, is convenient to mobile installation.Air inlet is shunted through multistage purification, discharging is exactly the air can breathed for staff, and the blow-off pipe of the greasy dirt filtered out in secondary current divider by bottom is discharged, greasy dirt during effective filtering pressure wind air feed in air, improve air degree of purity, the greasy dirt that blow-off pipe is discharged simultaneously flows into gutter, also ensure that the sanitation of environment of refuge chamber; Gas outlet is connected with noise damper by pipeline, sound absorber 3 is connected with reducing valve 301, can regulate pressure size, to reduce noise at any time according to indoor noise situations of surviving in refuge chamber.
