Abstract
The invention relates to an underground pressure air supply system of a refuge chamber and belongs to the technical field of air supply in the refuge chamber. The underground pressure air supply system of the refuge chamber solves the technical problems and is simple and reasonable in structure, capable of effectively filtering oil stain in the pressure air and high in air cleanliness. According to the technical scheme, the underground pressure air supply system comprises an air conveying pipe penetrating through a transition chamber of the refuge chamber, an air inlet of the air conveying pipe is arranged outside the refuge chamber, and an air outlet is formed in a survival chamber of the refuge chamber. The air inlet is provided with a control ball valve, and a branch air supply pipe is further arranged on the air conveying pipe. Three levels of air filters are arranged on the air conveying pipe, the bottoms of the front two levels of the oil filters are communicated with a sewage draining pipe, and a sewage draining ball valve is arranged on the sewage draining pipe. A drainage ditch is formed in the bottom of the transition chamber of the refuge chamber, and a sewage draining opening of the sewage draining pipe is communicated with the draining ditch. The underground pressure air supply system of the refuge chamber is simple in structure, capable of effectively filtering oil stain in the pressure air and high in air cleanliness and is widely applied to air supply of the refuge chamber.
Description
Technical field
The present invention relates to a kind of refuge chamber down-hole and press the wind air supply system, belong 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 after mine disaster occurs, the down-hole compressed-air system is not damaged, should pays the utmost attention to and press the 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 the wind air supply system, but there are the following problems:
(1) down-hole presses wind clean not, needs to adopt strainer to press wind to carry out the greasy dirt filtration to down-hole, and most of refuge chambers down-hole presses the wind air supply system not consider the discharge of greasy dirt;
(2) press the wind air supply opening pressure indoor in existence non-adjustable, cause the indoor noise of existence larger, worsened the environment in hedging space.
Summary of the invention
The present invention 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 the 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 solution adopted in the present invention is: the wind air supply system is pressed in the refuge chamber down-hole, comprise: the appendix that runs through the 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 the control ball valve, also be provided with branch's air supply pipe on described appendix, be provided with three grades of air filters on described appendix, before in described three grades of air filters, the bottom of two-stage air filter all is connected with blow-off pipe, be provided with Blowoff ball valve on described blow-off pipe, described refuge chamber transition chamber bottom is provided with gutter, the dirt-discherging outlet of described blow-off pipe is connected with gutter.
Also be provided with noise damper on the gas outlet of described appendix.
Described blow-off pipe is fixed on the wall of transition chamber in refuge chamber by pipe clamp.
Be provided with pressure meter between described three grades of air filters and reducing valve.
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 present invention compared with prior art had is: the present invention adopts and be provided with three grades of air filters on appendix, and the greasy dirt filtered out in three grades of air filters is discharged by the blow-off pipe of bottom, airborne greasy dirt when effectively the wind air feed is pressed in filtering, improve the 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, also be provided with reducing valve, can regulate the pressure size according to the indoor noise situations of surviving in refuge chamber at any time, to reduce noise.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is structural representation of the present invention.
In figure: 1 is appendix, and 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, and 10 is branch's air supply pipe, and 11 is pressure meter.
The specific embodiment
As shown in Figure 1, the wind air supply system is pressed in the refuge chamber down-hole, comprise: the appendix 1 that runs through the 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, also be provided with branch's air supply pipe 10 on described appendix 1, be provided with three grades of air filters 4 on described appendix 1, before in described three grades of air filters 4, the bottom of two-stage air filter all is connected with blow-off pipe 5, be provided with Blowoff ball valve 6 on described blow-off pipe 5, 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.
Also be provided with noise damper 8 on the gas outlet of described appendix 1.
Described blow-off pipe 5 is fixed on the wall of transition chamber in refuge chamber by pipe clamp 9.
Be provided with pressure meter 11 between described three grades of air filters 4 and reducing valve 3.
The gas outlet of described appendix 1 is provided with reducing valve 3.
Described appendix 1, blow-off pipe 5 and branch's air supply pipe 10 are the clean pipe of stainless steel.
