Abstract

The utility model discloses a compressed-air self-rescue box for a mine, which comprises an upper magnet suction part of a door closure, single control valves, an air-inflow main control valve and a box body, wherein the outer side of the box body is provided with an air-inflow port, and the inner end of the air-inflow port is connected into the box body to be connected with the air-inflow main control valve; two sides of the air-inflow main control valve are provided with a plurality of single control valves; the upper side in the box body is provided with the upper magnet suction part of the door closure; a plurality of telescopic pipes are evenly distributed in the cavity of the box body; and one end of each telescopic pipe is provided with a breathing mask. The compressed-air self-rescue box for the mine has the beneficial effect that when coal and gas outburst potential exists or harmful gas exists, field personnel can quickly move to the compressed-air self-rescue device to press the button of a box door; after the box door is opened, the device can quickly supply air, people avoiding disasters can breathe only by wearing the mask to wait for rescue without carrying out other operations; and the compressed-air self-rescue box for the mine has the characteristics of stable air supply amount, is convenient, quick, stable and reliable and is favorable for automatically draining, air can be automatically supplied, and the supplied air is filtered.

Description

Mining compressed air self-help case

Technical field

The utility model relates to mining self-help apparatus, relates in particular to a kind of mining compressed air self-help case.

Background technology

Generally give prominence at coal and gas, the mine of spontaneous fire easily takes place, and in the machine lane of down-hole chamber, coal-face, air way and scraper-trough conveyer head, shaft station, transportation and return aircourse, the pump house of driving face or select the more place of the stream of people, when generation tunnel roof fall, coal and gas are given prominence to or outstanding omen are arranged, the staff can't take the measure of saving oneself fully rapidly, lack effective self-help apparatus, as put on respirator and save oneself, wait for rescue etc.

The utility model content

At above defective, the purpose of this utility model provides that quick, reliable and stable, the automatic air-supply of a kind of convenience, wind supply quantity are stable, powered air-purifying, help self-draining mining compressed air self-help case, to solve many deficiencies of prior art.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of mining compressed air self-help case, comprise magnet adhesive portion, individual event control valve, air inlet main control valve and casing on the door closure, the described casing outside is provided with intake interface and box house connection air inlet main control valve is inserted in its inner end, described air inlet main control valve both sides are provided with some individual event control valves, described box house upside is installed magnet adhesive portion on the door closure, even distribution several expansion pipe in the cabinets cavity, an end of each telescoping tube is provided with breathing mask.

The beneficial effect of mining compressed air self-help case described in the utility model is: when taking place that coal is given prominence to gas or during pernicious gas, the field personnel can be rapidly to compressed air self-help apparatus, press the lower chamber door button, chamber door is opened the back device and is supplied gas automatically, keep away the calamity personnel and need not to carry out any other operation, take out to breathe again after face shield is put on and wait for rescue, have that convenient quick, reliable and stable, automatic air-supply, wind supply quantity are stable, powered air-purifying, help characteristics such as automatic draining; Can be mainly used in coal and gas outstanding, easily the mine of spontaneous fire takes place, be installed in down-hole chamber, coal-face machine lane, driving face air way and scraper-trough conveyer head, shaft station, transportation and return aircourse, pump house or select the more place of the stream of people; This device inside is equipped with six breathing masks and is made as one group and be enclosed in the stainless steel casing, connects the back with air line and forms a down-hole air feed self-help apparatus system.

Description of drawings

According to embodiment and accompanying drawing the utility model is described in further detail below.

Fig. 1 is the structural representation of the described mining compressed air self-help case of the utility model embodiment.

Among the figure:

1, magnet adhesive portion on the door closure; 2, individual event control valve; 3, air inlet main control valve; 4, Pressure gauge; 5, breathing mask; 6, air feed adjusting knob; 7, telescoping tube; 8, intake interface; 9, casing.

The specific embodiment

As shown in Figure 1, mining compressed air self-help case described in the utility model, comprise magnet adhesive portion 1, individual event control valve 2, air inlet main control valve 3 and casing 9 on the door closure, described casing 9 outsides are provided with intake interface 8 and connection air inlet main control valve 3 in the casing 9 is inserted in its inner end, described air inlet main control valve 3 both sides are provided with some individual event control valves 2, each individual event control valve 2 tops configuration Pressure gauge 4; Described casing 9 upper inside are installed magnet adhesive portion 1 on the door closure, even distribution several expansion pipe 7 in casing 9 inner chambers, and the two ends of each telescoping tube 7 are respectively equipped with air feed adjusting knob 6 and breathing mask 5.During use, when the pressure in the compressed-air system is between 0.3-0.7Mpa, through intake interface 8, air inlet main control valve 3, enter the filtration decompression valve, by pressure-reducing valve pressure being set up is laggard line output between the 0.05-0.1Mpa, the pressure personnel of saving oneself after the setting breathe comfortable nature, simultaneously the tolerance of output is filtered, moisture can discharge automatically, after the personnel of saving oneself put on cover, because unidirectional check is adopted in the face shield both sides, the toxic gas of OFP can not enter in the cover, but personnel's fresh respiratory gas body of saving oneself.

Claims
