Description
Technical field
The utility model relates to a kind of refuge chamber down-hole and presses wind air supply system, belongs to refuge chamber supply technology field.
Background technology
In refuge chamber, the design of gas supply system should be considered two kinds of situations: a kind of is, when down-hole compressed-air system is not damaged after mine disaster occurs, should pays the utmost attention to and press wind air feed, can realize endless air feed, maintains the longer hedging time; Another kind of situation is to press wind to be destroyed, and now adopts standby compressed air air feed.At present, the refuge chamber great majority that occur on market have all designed down-hole and have pressed wind air supply system, but there are the following problems:
(1) down-hole presses wind clean not, need to adopt strainer to press wind to carry out greasy dirt filtration to down-hole, and most of refuge chambers down-hole presses wind air supply system not consider the discharge of greasy dirt;
(2) press wind non-adjustable at the indoor air supply opening pressure of existence, cause the indoor noise of existence larger, worsened the environment in hedging space.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved has been to provide a kind of simple and reasonable for structure, and effectively the greasy dirt in wind is pressed in filtering, and wind air supply system is pressed in the refuge chamber down-hole that air purity is high.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: wind air supply system is pressed in a kind of refuge chamber down-hole, comprise: the appendix that runs through refuge chamber transition chamber, the air inlet port of described appendix is arranged on the outside of refuge chamber, gas outlet is arranged on the existence chamber of refuge chamber, described air inlet port is provided with control ball valve, on described appendix, be also provided with branch's air supply pipe, on described appendix, be provided with three grades of air filters, before in described three grades of air filters, the bottom of two-stage air filter is all connected with blow-off pipe, on described blow-off pipe, be provided with Blowoff ball valve, described refuge chamber transition chamber bottom is provided with gutter, the dirt-discherging outlet of described blow-off pipe is connected with gutter.
On the gas outlet of described appendix, be also provided with noise damper.
Described blow-off pipe is fixed on the wall of transition chamber in refuge chamber by pipe clamp.
Between described three grades of air filters and reducing valve, be provided with pressure meter.
The gas outlet of described appendix is provided with reducing valve.
Described appendix, blow-off pipe and branch's air supply pipe are the clean pipe of stainless steel.
The beneficial effect that the utility model compared with prior art had is: the utility model adopts and on appendix, is provided with three grades of air filters, and the greasy dirt filtering out in three grades of air filters is discharged by the blow-off pipe of bottom, airborne greasy dirt when effectively wind air feed is pressed in filtering, improve air degree of purity, the greasy dirt that blow-off pipe is discharged simultaneously flows into gutter, has also guaranteed the sanitation of environment of refuge chamber; When the gas outlet of appendix is provided with noise damper, be also provided with reducing valve, can according to the noise situations of surviving indoor in refuge chamber, regulate pressure size at any time, to reduce noise.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1 is appendix, 2 for controlling ball valve, and 3 is reducing valve, and 4 is three grades of air filters, and 5 is blow-off pipe, and 6 is Blowoff ball valve, and 7 is gutter, and 8 is noise damper, and 9 is pipe clamp ，10Wei branch air supply pipe, and 11 is pressure meter.
The specific embodiment
As shown in Figure 1, wind air supply system is pressed in a kind of refuge chamber down-hole, comprise: the appendix 1 that runs through refuge chamber transition chamber, the air inlet port of described appendix 1 is arranged on the outside of refuge chamber, gas outlet is arranged on the existence chamber of refuge chamber, described air inlet port is provided with controls ball valve 2, on described appendix 1, be also provided with branch's air supply pipe 10, on described appendix 1, be provided with three grades of air filters 4, before in described three grades of air filters 4, the bottom of two-stage air filter is all connected with blow-off pipe 5, on described blow-off pipe 5, be provided with Blowoff ball valve 6, described refuge chamber transition chamber bottom is provided with gutter 7, the dirt-discherging outlet of described blow-off pipe 5 is connected with gutter 7.
On the gas outlet of described appendix 1, be also provided with noise damper 8.
Described blow-off pipe 5 is fixed on the wall of transition chamber in refuge chamber by pipe clamp 9.
Between described three grades of air filters 4 and reducing valve 3, be provided with pressure meter 11.
