[0040] Such as figure 1 As shown, the oxygen candle of this embodiment includes an oxygen candle starting device, an oxygen candle generator and a filter body.

[0041] The oxygen candle generator is installed under the oxygen candle starting device, and the two are sealed and connected, and the filter body is installed under the oxygen candle generator, and the two are also sealed and connected.

[0042] The oxygen generator comprises a charge shell 22, the top of the charge shell 22 is provided with a through hole, the bottom of the charge shell 22 is provided with an air outlet, and a filter body is installed at the air outlet; the fire cap of the oxygen candle starting device passes through the through hole In contact with the oxygen candle medicine, the pull wire column of the oxygen candle starting device is in sealing connection with the charging shell, and the filter body is in sealing connection with all air outlets. Wherein, the bottom of the wire column and the cha...

Embodiment 3

[0053] Absorb flammable layer 10g altogether, each component ratio is (mass percentage): chlorate 0.2%, magnesium powder 10%, barium chromate 85%, kaolin 4.8%;

[0054] The heating element layer is 52.1g, and the ratio is (mass percentage) 73% of sodium chlorate, 4% of tricobalt tetroxide, 6% of manganese dioxide, 5% of iron powder, 7% of cobalt powder, and 5% of kaolin.

[0055] Main candle body layer 300.05g, the ratio is (mass percentage) sodium chlorate 95%, potassium perchlorate 0.5%, tricobalt tetroxide 0.7%, manganese dioxide 0.8%, cobalt powder 1.0%, kaolin 2.0%. First, dry the chlorate in an infrared oven at 120°C for 30-60 minutes, then use a ball mill and a double-screw mixer to mix it evenly with other weighed materials, and add a certain amount of NaCrO with a concentration of 0.5-2%. 4 The aqueous solution is fully mixed, demolded and pressed into H=23mm oxygen-generating drug block; dried in an infrared drying oven at 120°C for 1 hour.

Abstract

The invention discloses an oxygen candle. The disclosed oxygen candle comprises an oxygen candle starting device and an oxygen candle generator. The oxygen candle starting device comprises a stay wirecolumn and an igniter cap. A stay wire hole is arranged in the stay wire column along with the axis of the stay wire column. An igniter cap cavity is arranged in the interior of one end of the stay wire column. A waterproof cavity is arranged in the interior of the other end of the stay wire column. The stay wire hole penetrates the waterproof cavity and the igniter cap cavity. The igniter cap isarranged in the igniter cap cavity, and sand is filled in the waterproof cavity. The oxygen candle generator comprises a charging shell. The top of the charging shell is provided with a through hole.The bottom of the charging shell is provided with vent holes. The vent holes are provided with a filtering body. The igniter cap of the oxygen candle starting device is contacted with an oxygen candle drug through the through hole. The oxygen candle generator is hermetically connected to the charging shell. The filtering body is hermetically connected to all vent holes. The oxygen candle adopts adraw type oxygen candle device. The mechanical starting structure of a conventional oxygen candle is simplified. The false start caused by falling of a steel needle is avoided, and the reliability isimproved.

Description

technical field [0001] The invention belongs to the technical field of solid chemical oxygen self-rescuer equipment, and in particular relates to an initial oxygen source starting device for a chemical oxygen self-rescuer, especially an oxygen candle with a pull-out starting device. Background technique [0002] Oxygen generator is to arrange oxygen candle in the container that offers vent hole now, and a mechanical starting device that can cause to release oxygen is set on the container top. The device hits the fire cap through mechanical striking, and the fire cap generates high temperature, which ignites the oxygen candle in the container, so that a high concentration of oxygen is generated from top to bottom. However, this kind of mechanical starting has complicated mechanical structure, time-consuming assembly, high cost of the flash cap, easy occurrence of steel needle falling off, and open flame generation. Contents of the invention [0003] Aiming at the defects o...
