Abstract
The invention of describing is the respiratory protection equipment that an oxygen self-rescuer forms, and it comprises a chemical cartridge case (1) that oxygen takes place, and cartridge case is contained in breathing bag (5) the inside, and it is sealed fully.Chemistry cartridge case (1) is covered and is fixed on the upper surface of breathing bag by a jacket.This design has obtained a compact especially respiratory protection equipment.
Description
The invention relates to the respiratory protection equipment of an oxygen self-rescuer form, it is consistent to can be used as declaratives of escaping device and claim 1 especially.
At the sort of airtight closable slack tank of respiratory protection equipment of beginning narration, for example,, carry by the miner usually applicable to mine work.Slack tank can be enabled at any time.
Obviously, such respiratory protection equipment must be light and small and exquisite, because the miner must carry at any time.
In the respiratory protection equipment of doing by technology in the past, breathing bag is on chemical cartridge case, and chemical cartridge case is positioned at the bottom of this equipment, and the breathing bag that has respiratory siphon and a suction inlet is contained on the lid of this equipment.This just requires lid that suitable intensity is arranged, and it has just become a big chunk of slack tank, makes respiratory protection equipment and slack tank must rely on a braces to back on the body.Under the very arduous condition of mine work, it is very uncomfortable that the miner carries it at any time.
So main purpose of the present invention provides a small and exquisite and compact especially design, make to be loaded in an oxygen self-rescuer and escape device and can be contained on the slack tank on people's the waistband.
The respiratory protection equipment of beginning narration can reach this purpose by the feature that claim 1 provides.
The structure size that the invention has the advantages that respiratory protection equipment is reduced to such degree equipment that makes and can be contained in the little slack tank, can be loaded on user's the waistband.Additional advantage is that chemical cartridge case has adopted perfect double-layer seal, that is to say to have adopted sleeve and breathing bag, has reduced the surface temperature of respiratory protection equipment.
Originally the heat that discharges of the imagination chemical cartridge case at work will be to the unallowable burden in addition of inhaled air in breathing bag and the breathing bag, yet the present invention has proved that with its excellent style it is possible that chemical cartridge case is placed in the breathing bag.But in the former technology, breathing bag will adopt the whole bag of tricks that the thermal transpiration that chemical cartridge case produces is fallen.
Further specializing of advantage of the present invention seen more obviously from sub-claim.
Detail of the present invention provides in the drawings, below for a more detailed description.
Fig. 1 represents a schematic diagram according to the respiratory protection equipment of reciprocating type breathing of the present invention.
Fig. 2 is the profile that I-the I line is cut in Fig. 1.
Fig. 3 represents a schematic diagram according to the respiratory protection equipment of closed type breathing of the present invention.
Fig. 4 is a schematic diagram that is placed on a respiratory protection equipment in the slack tank according to the present invention.
Fig. 5 is the enlarged detail that indicates the X place in Fig. 4.
Respiratory protection equipment according to a reciprocating type breathing of the present invention is given in Fig. 1.Respiratory protection equipment consists of the following components: the chemical cartridge case 1 that oxygen takes place, and it is wrapped tightly by the sleeve 2 of a thermal insulation and damping; A root breath pipe 3 that has suction inlet 4; Be attached at a breathing bag 5 on the chemical cartridge case 1; And carry 6.Fig. 4 has provided a respiratory protection equipment that is contained in the slack tank.
A heat exchanger 12 is arranged at the top at the inlet D of chemical cartridge case 1, and it is designed to prevent the thermo-contact between heat exchanger 12 and the chemical cartridge case 1.Heat exchanger is surrounded by the frame cover 17 of a thermal insulation, and this frame cover is fastened the upper surface at chemical cartridge case 1.
At the upper surface 5a of breathing bag 5 an opening 5b is arranged, by this opening, chemical cartridge case is inserted into breathing bag.Opening 5b is surrounded by a reinforcement 5c, the chemical cartridge case 1 of band sleeve 2 and carry 6 end rely on clip 22 be fixed on it above.At the upper surface 5a of breathing bag 5 pressure-reducing valve 8 is housed.
Fig. 2 has provided the profile of the chemical cartridge case 1 that has sleeve 2.Sleeve 2 has some raised line 2a to be spaced and the surface (A) of chemical cartridge case closely cooperates in its vertical direction and/or longitudinal axis direction by certain.
In order utilize to produce the chemicals of oxygen best, allow uniform air flow through the space of whole chemicals, so just increased the service life of the respiratory protection equipment in working.This is to realize that by a circulation area of doing greatly as far as possible directly the air outlet slit with the user enters chemical cartridge case 1 by respiratory siphon 3, falls with side direction vertically from top, and radial ground from outside to inside.Relevant with this, air outlet slit face E gives prominence to and form a cover in chemical cartridge case 1.The direction of circulation is represented by arrow.
The topped one deck absorbent cotton 9 of air outlet slit face E pine loose ground enters breathing bag 5 to prevent the chemical powder that is contained in the chemical cartridge case 1.For the chemicals that prevent to melt flow into breathing bag 5 from chemical cartridge case 1, put in the air outlet slit B of cartridge case 1 with an acute angle with a filter screen 10, cover this outlet, the chemicals of some fusing are stayed in the drip trays of chemical cartridge case 1 bottom formation, the path of air is not got clogged.
Fig. 3 has provided the respiratory protection equipment by closed circuit breathing design of the present invention.Structure is identical with the respiratory protection equipment that Fig. 1 provides, and different just has two outlet valves 18 and heat exchanger 12 on the framework.Framework 13 is pushed, rely on socket be fixed to chemical cartridge case 1 ' inlet D ' locate, that is to say by means of a pipe junctor 19 to be inserted in the pipe socket 20 that is connected on the framework 13 as population D '.Rely on padding 21, socket 20 can be to plug 19 sealings.
Air directly sucks by framework 13 from breathing bag 5, and sleeve 2 provides hole 2b.This makes equipment realize closed circuit breathing.Only respiratory siphon 3 is used for breathing out and sucking promptly reciprocating type breathing.The chemistry cartridge case 1 ' airflow direction represent with arrow.
Fig. 4 has represented the respiratory protection equipment in slack tank.The can body of slack tank marks by 14, and cover marks by 15.Two parts rely on blocking element (not showing) to force together, and form a hermetic seal, and this all knows in technology in the past.Standby eyelet 16 on the slack tank 7 allows the user that slack tank is buckled on the waistband.
Respiratory protection equipment in slack tank 7 must be shockproof.This is to make outstanding round pin 2C by the limit of the top of sleeve 2 and bottom one circle to realize well.
Fig. 5 is the zoomed-in view of outstanding circle pin 2C, and it is as the damper between the wall of chemical cartridge case 1 and slack tank 7 can body parts 14.
