Description
Technical Field
The utility model belongs to mining self-rescuer equipment field especially relates to an oxygen supply device for self-rescuer.
Background
At present, KO is used as the oxygen supply mode of the mine self-rescuer in China2(Potassium superoxide) and medical oxygen as oxygen source, KO2The gas cylinder is easy to react with water vapor and carbon dioxide under the condition of poor sealing condition to generate a large amount of heat, so that the gas cylinder is easy to explode when the temperature of the high-temperature gas cylinder is too high or the gas cylinder is impacted to cause gas leakage.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an oxygen supply equipment for self-rescuer, it has solved the easy problem that explodes of current mining self-rescuer oxygen supply equipment.
The utility model aims at solving through the following technical scheme:
an oxygen supply device for a self-rescuer comprises an oxygen candle driving piece, a fire guiding piece, a candle body, an oxygen candle shell and an oxygen candle bottom shell;
the oxygen candle driving piece is connected with the fire leading piece;
the fire guide piece is abutted with the candle body;
the candle body is positioned in the oxygen candle shell;
the oxygen candle bottom shell is positioned at the bottom of the oxygen candle shell and is connected with the oxygen candle shell;
the candle body is chlorate.
Further: the oxygen candle driving piece is an oxygen candle pull ring.
Further: the fire leading piece is a fire cap.
Further: a layer of heat insulation cotton is arranged between the candle body and the oxygen candle shell.
Further: the oxygen candle shell is internally provided with a filter layer, the top of the filter layer is provided with a carrier plate, and the carrier plate is connected with the oxygen candle shell.
Further: the candle body is potassium chlorate.
Further: the candle body is sodium chlorate.
Compared with the prior art, the beneficial effect that this application has is: the candle body is ignited by the fire-guiding piece, and generates oxygen through self reaction for the self-rescuer, so that the candle body cannot explode, and fire disasters are effectively avoided;
further: through having the thermal-insulated cotton of one deck between the candle body and oxygen candle shell, prevent that the user from being scalded to the shell.
Drawings
Fig. 1 is a sectional view of the oxygen supply device of the present invention.
Wherein: 1. an oxygen candle pull ring; 2. a fire cap; 3. an oxygen candle housing; 4. heat insulation cotton; 5. a candle body; 6. a carrier plate; 7. an oxygen candle bottom shell; 8. a filter layer.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings:
as shown in fig. 1, the oxygen supply device for the self-rescuer comprises an oxygen candle pull ring 1, a fire cap 2, a candle body 5, an oxygen candle shell 3 and an oxygen candle bottom shell 7;
oxygen candle pull ring 1 and 2 welding of fire cap, fire cap 2 and 5 butts of the candle body, and the candle body 5 is located oxygen candle shell 3.
The candle body 5 is chlorate, preferably potassium chlorate or sodium chlorate.
Set up the thermal-insulated cotton 4 of one deck between the candle body 5 and the oxygen candle shell 3, prevent that the user from being scalded to the shell.
Be provided with filter layer 8 in the oxygen candle drain pan 7, filter layer 8 top sets up carrier plate 6, and carrier plate 6 is connected with oxygen candle shell 3, and carrier plate 6 is with the separation of candle body 5 and filter layer 8.
The working process is as follows: oxygen candle pull ring 1 is connected with fire cap 2, and pulling oxygen candle pull ring 1, fire cap 2 light the candle body 5, and the candle body 5 generates oxygen through spontaneous heating sustained reaction, has the thermal-insulated cotton 4 of one deck between the candle body 5 and oxygen candle shell 3, prevents that the shell from scalding the user of service, and oxygen candle drain pan 7 passes through laser welding shaping with oxygen candle shell 3, has filter layer 8 in the oxygen candle drain pan 7, and the carrier plate 6 is with the separation of the candle body 5 and filter layer 8. Oxygen generated by the oxygen candle escapes from the bottom of oxygen candle base 7 through filter layer 8.
The candle body 5 generates oxygen through self reaction for the self-rescuer, the candle body 5 can not explode, and the fire disaster is effectively avoided.
