Description

Positive-pressure air respirator

Technical field

The utility model relates to positive pressure respiration instrument and equipment technical field, specially a kind of positive pressure respirator.

Background technique

In productive labor, safe and healthy is one of the factor of most basic consideration.But it works in actual hostile environment In, how to protect worker in toxic gas environmental work and is not injured the health for ensuring body by toxic gas to greatest extent A urgency to the problem of.Positive pressure respirator is that one kind is widely used under dense smoke, toxic and harmful gas, dust, anaerobic environment A kind of respiratory protection utensil.The common structure of positive pressure respirator is gas source part and breathing mask at present, and gas source part uses The mode of high pressure gas cylinder gas supply, has the shortcomings that pressure is big, volume is big, service life is short, is not suitable for continual for a long time Respiratory protection.And it can be directly using existing in being engaged in the environment that spray painting, coal mine, nonferrous metal mine etc. have ventilation equipment in itself Field pressure wind supplies gas source, and high pressure gas cylinder need not be carried by supplying in the gas source for being directly used in respirator after the processing such as filtering Gas supply.Particularly important are just shown to some respiratory apparatus protections for being engaged in the workers such as spray painting, therefore original air is compressed Air is efficiently used in machine, is not influencing industrial production to use while can also be used as respirator to be a new invention skill Art.The gas for making full use of air compressor to produce has unwholesome substance by the filter unit for installing special additional Effect thoroughly processing, then by quick coupling connecting pipe, self-supporting steam supply valve, mask, supply human body respiration use is a Xiang Feichang Beneficial technology, therefore improvements over the prior art are very important.

Utility model content

The purpose of the utility model is to overcome above-mentioned deficiency, providing a kind of can directly be supplied using the existing air in scene The positive pressure respirator that gas source is breathed, filter effect is good, easy to use.

The used technical solution of the technical issues of the utility model solves is:

Positive-pressure air respirator, it is characterized in that including oil water separator and the antitoxic filtration tank group that multiple groups concatenate, gas defence Filtering tank group includes active carbon filter and molecular sieve filter, and active carbon filter and molecular sieve filter mutually concatenate, gas Source capsule road is successively connected in series and is connect with oil water separator, antitoxic filtration tank group by intake valve, the antitoxic filtration tank of last group The gas output end of group is connected by output airway with the filtration mask for being equipped with self contained steam supply valve.

It is except impurity such as excessive moisture, oil in air that oil water separator, which goes major function,.

Active carbon filter is the process for retaining the pollutant of suspended state, and the suspended matter being trapped is filled in work Gap between property charcoal.

For molecular sieve filter using molecular sieve as filtering goods and materials, molecular sieve derives from physical absorption to the absorption of substance (Van der Waals force) has very strong polarity and Coulombian field inside crystal hole, to polar molecule (such as water) and unsaturated molecule table Reveal strong adsorption capacity.The pore-size distribution of molecular sieve is very uniform, and only molecular diameter is less than the substance of hole diameter Inside the bug hole of molecular sieve.

The utility model is combined using the active carbon filter and molecular sieve filter of antitoxic filtration tank group to passing through The filtered gas of oil water separator is filtered, and based on adsorbing, molecular sieve can be filtered effectively active carbon based on stopping Impurity in air.The utility model carries out the impurity such as excessive moisture, the oil in purified treatment removal air to the air of output simultaneously Reach clear, safe air, gas enters breathing mask by output duct, provides user's use, matches on breathing mask There is steam supply valve, tolerance can be automatically controlled according to the inspiratory capacity of user for normal use.It is supplied in a manner of positive pressure self-sufficiency gas supply Human body respiration uses, and such air compressor both can be used as production equipment use, can also be used as filtration mask gas Source provides use.The original gas mask by user itself lung capacity self-priming is more modified to self-supporting Gas feeding gas mask, Both improved user comfort level also reduce worker labour harm more improve Health Category.

The utility model carries out the impurity such as excessive moisture, the oil in purified treatment removal air and reaches clear, safe Air both may be implemented to use on the workplace of compressor for the expiration of people, and the breathing that can also provide people is used, It is convenient and practical, promotional value with higher.The utility model reduces the labour harm of worker, improves as respiratory protection Health Category.

When it is implemented, antitoxic filtration tank group is two to four groups.

When it is implemented, the gas output end of the antitoxic filtration tank group of last above-mentioned group is equipped with the road 3-10 output airway, Each output airway is connected with the filtration mask for being equipped with self contained steam supply valve respectively.

When it is implemented, oil water separator is equipped with automatic drain valve.

When it is implemented, molecular sieve filter is equipped with observation pressure gauge.

When it is implemented, every road output airway of the gas output end of the antitoxic filtration tank group of last group is equipped with output Pressure gauge.

The beneficial effects of the utility model are: compared with prior art, the gas defence concatenated by oil water separator and multiple groups For filtering tank group as gas-filtering device, effect is obvious；By filtered pure air, the filtering type gas defence equipped with steam supply valve The original gas mask by user itself lung capacity self-priming is modified to self-supporting Gas feeding gas mask, both improved by mask The labour harm that the comfort level of user also reduces worker more improves Health Category, helps the work under dust adverse circumstances The personnel of work improve life quality.
