The specific embodiment
Shown in Figure 1, a kind of compressed air self-help system comprises air-supply arrangement 1, compressed air self-help device 2, fast dismounting joint 3 and breathing mask 4.
In the present embodiment, air-supply arrangement 1 comprises the air compressor 10 that is arranged at ground, the compressed air that air compressor 10 produces is stored in the air accumulator 11 in advance, and the air pressure in the air accumulator 11 are subjected to an intelligent pressure gauge tap 12 controls, and its air pressure maintains between 0.3Mpa and the 0.7Mpa.The compressed air that comes out from air accumulator 11 can tentatively filter through one-level filter 5 earlier before entering air duct, solid particle with oil gas a large amount of in the filtering air, water and larger volume, compressed air after preliminary the filtration is in air duct is imported compressed air self-help device 2, supplying with underground job hedging personnel after noise reduction, filtration, purification, decompression are come out breathes, for the hedging personnel provide comfortable, the breathe air of health.
Shown in Figure 2, compressed air self-help device 2 is a device that integrates noise reduction, filtration and purification function, it has a cavity 20, the input installing silencing means of cavity 20, this silencing means comprises that a surface has the hush pipe 21 of some apertures, hush pipe 21 outer cavity 20 inwalls are provided with the material foamed aluminium 24 that is used for noise reduction, output installing filter course 22, and the input bottom also is provided with the discharge outlet 23 of a belt switch.Compressed air self-help device 2 links to each other with pressure-reducing valve 6 by air duct, and silencing means 21 wherein makes noise that compressed air produces below 70 decibels, provide one quiet relatively, environment avoids the user of service to produce intense strain easily; And filter course 22 can be divided into successively along airflow direction: three groups of overanxious layers 221 of glass fibre, 222,223 and one groups of active carbon filtration layers 224, wherein, the overanxious layer 221 of ground floor glass fibre is used for hydrocarbon filters a large amount of in the compressed air below 5PPM, the impurity particle filtering is to 5MICRON, the overanxious layer 222 of second layer glass fibre is used for the oil gas filtering in the compressed air below 0.5PPM, the impurity particle filtering is to 1MICRON, the triplex glass fiber is used for the oil gas filtering in the compressed air below 0.01PPM for overanxious 223 layers, the impurity particle filtering is to 0.01MICRON, active carbon 224 filter courses are used for the foul smell and the very fine oil gas and the ultramicro powder of filtering compressed air, compressed air is played catharsis, after 22 pairs of compressed air multiple times of filtration of filter course, can provide the hedging personnel air of clean hygiene.
Compressed air self-help device 2 outputs are equipped with pressure-reducing valve 6 and are used to show the air gauge of current pressure, link to each other with the arm 41 at breathing mask 4 places through a fast dismounting joint 3 again.
As shown in Figure 3, fast dismounting joint 3 comprises a male end plug 31 and a plurality of female end socket 32.Breathing mask 4 links to each other with the flexible pipe of giving vent to anger and forms arm 41, each hose free end of giving vent to anger that links to each other with breathing mask 4 have one can be adaptive with described female end socket 32 male end plug 31.A plurality of fast dismounting joints 3 can be connected in one fast by mutual grafting between male end plug 31 and the female end socket 32.Breathing mask 4 utilizes the male end plug 31 that is connected the hose free end of giving vent to anger, and also can be connected with the female end socket 32 of fast dismounting joint 3 easily.Therefore, in use, can change the quantity that fast dismounting joint 8 and breathing mask 4 insert flexibly according to what of personnel, access between them and dismounting can be finished in a flash.When blast, during dangerous situation such as landslide, gas are outstanding, fire, personnel can go to the set-point that native system is housed nearby on the working face, put on the breathing mask 4 in the native system, open valve, save oneself.With also can install an airflow regulating switch on the flexible pipe of giving vent to anger that breathing mask 4 links to each other, pressure and air mass flow can be regulated by this airflow regulating switch.If the people is many, the breathing mask 4 on the device is not enough, can pick up standby fast dismounting joint 3, is pressed on the mounted joint, and they are connected as a single entity (as shown in Figure 4), inserts backup breaths face shield 4 again, can save oneself.Whole device is very flexible, has avoided the fixedly compressed air self-help system difficult situation in this case of number use.
The existing relatively compressed air self-help apparatus of native system, erasure effect is better, and the filtration, purification performance is better, and simple in structure, cheap, the more important thing is that number of users is unrestricted, can expand the breathing port fast according to number of users, be suitable for the emergent use under the catastrophe emergency case.
The above is the preferred embodiment for inventing only; it is not qualification to the invention practical range; in the ken that those of ordinary skills possessed; design main points based on this case; also can make many variations to its concrete example; promptly the saving oneself of Field Force when making it be applicable to something unexpected happened such as tunnel, subway, but all should fall within the scope of protection of the present invention.
