Abstract
The utility model relates to a chemical oxygen candle oxygen producer which comprises a trigger and an oxygen generator composed of a heat generating agent, an oxygen candle body, an insulating sleeve and a filter. The utility model is characterized in that an external circle between the heat generating agent and the oxygen candle body is sheathed with a metal protecting ring, and the trigger is provided with a conical pressure expanding port, the oxygen candle body is pressed into a square shape, and the heat generating agent and the oxygen candle body are all covered by the insulating sleeve. The utility model with the improved structure not only enhances triggering reliability, ensures the uniformity and stability of oxygen releasing and simplifies a technology, but also reduces the resistance of an air flow and reduces the heat loss at low temperature and the heat conduction at high temperature so as to have good technical indexes.
Description
The utility model relates to a kind of chemical oxygen candle oxygen generator.
The oxygen supply of existing employing chemical method system oxygen is more, but in use find: because the density of exothermic mixture is different with oxygen candle main body with thermal discharge, exothermic mixture is vibrated after initiation or influenced by service orientation, sometimes can not transmit heat effectively, under cryogenic conditions, the situation of oxygen candle can appear more reliably causing particularly; Existing main body oxygen candle adopts cylindrical always, not only the density of each section differ to and to cause putting oxygen inhomogeneous, and pressing process is also complicated; Existing ceramic jacket all is to be positioned at the exothermic mixture part, like this, is positioned at the influence that oxygen candle beyond the ceramic jacket is subjected to environment temperature easily, causes that to put oxygen stable inadequately.
The purpose of this utility model just provides a kind of chemical oxygen candle oxygen generator, to address the above problem, makes the oxygen generator structure more perfect, more reliable performance, and have favorable manufacturability and good technical indicator.
The technical solution of the utility model is: comprise initiator and the oxygen generator that constitutes by exothermic mixture, oxygen candle main body, insulation sleeve and filter wherein the cylindrical between exothermic mixture and oxygen candle body be with the metal coating circle.
This is because the density of exothermic mixture is different with oxygen candle main body with thermal discharge, and exothermic mixture is vibrated or influenced by service orientation after initiation, can not transmit heat effectively sometimes, particularly under cryogenic conditions, more can occur reliably causing the situation that oxygen is lit up.For this reason, in technique scheme, the cylindrical of the utility model between exothermic mixture and oxygen candle main body increases a metal coating circle, thereby can transmit heat effectively, to improve the reliability that causes.
Initiator of the present utility model has taper diffusion mouth, and retaining is ignited impulsive force that the back-up ring of cap can not produce when causing igniter cap and dropping out influence the air-tightness of initiator, to improve the reliability of initiation.
Oxygen candle main body of the present utility model is square, the oxygen candle density that is pressed into square its each section of oxygen candle main body is all consistent, guaranteed to put the uniformity of oxygen, simultaneously, square oxygen candle pressing process is simple, can make the one-shot forming of oxygen candle is an integral body, has guaranteed to put the continuity of oxygen, and can make the oxygen candle of putting oxygen for a long time.
Jacket of the present utility model all covers exothermic mixture and oxygen candle body, both can play adiabatic effect, simultaneously, oxygen is lit up, and oxygen generator that this thermal chemical reaction puts oxygen is reduced by the influence property of environment temperature, thereby has improved the oxidative stability of putting under different temperatures.And because the oxygen candle is square, and insulation sleeve can be circular or other shape, just forms the space between oxygen candle and the insulation sleeve, thereby helps reducing the aeration resistance of putting the oxygen face.
The chemical oxygen candle oxygen generator that the utility model provides is simple in structure, reasonable in design, by improvement to existing oxygen generator structure, improved the reliability that causes greatly, uniformity and stability that oxygen is put in assurance simultaneously, and the resistance when both having reduced gas and flowing out, the heat conduction when heat loss in the time of being reduced in low temperature again and high temperature the utlity model has good manufacturability and good technical indicator thereby make.
Describe in detail below in conjunction with the embodiment accompanying drawing.
At first accompanying drawing is described.
Fig. 1 represents structure chart of the present utility model;
The profile of Fig. 2 presentation graphs 1.
Referring to Fig. 1, the utility model comprises initiator (1), and it is mechanical initiator, causes igniter cap by mechanical shock, produces heat.The bottom of initiator (1) is a taper diffusion mouth.The below of initiator (1) is followed successively by exothermic mixture (3) and oxygen candle main body (4); pack into after covering in the shell (8) by pottery (2); wherein the cylindrical between exothermic mixture (3) and oxygen candle main body (4) is with metal coating circle (7); the good copper material of general optional thermal conductivity; and oxygen candle main body (4) is pressed into square; and ceramic insulation cover (2) is circular; as shown in the figure; oxygen candle body below is filter (5); for preventing that the too high unsafe conditions of oxygen pressure that a variety of causes causes from taking place, and is provided with a safety valve (6).
Claims (4)
1. a chemical oxygen candle oxygen generator comprises initiator and the oxygen generator that is made of exothermic mixture, oxygen candle main body jacket and filter, it is characterized in that the cylindrical between exothermic mixture (3) and oxygen candle main body (4) is with metal coating circle (7).
