Description
Technical field
This utility model relates to air filter unit field, particularly relates to a kind of powered supplied air dust-proof rebreather.
Background technology
Pneumoconiosis is that a kind of labourer sucks dust and the lung fibrosis that occurs for a long time
Disease, pneumoconiosis patients all has existence in countries in the world, especially with developing country for very.At present, in China's duty
Industry disease is fallen ill in total case load, and pneumoconiosis patients accounting, more than 80%, occupies first of occupation disease.
The pneumoconiosis cause of disease is clear and definite, can not be cured.Measure for pneumoconiosis is only avoided and reduces suction dust
Prevent.Therefore, long-term work needs to wear protective mask or face shield in the labourer of dust atmosphere.Common
Mask type have: cotton cloth respirator, isolated mask and filter-type respirator.Cotton cloth respirator has been proved to right
In the unshielded effect of respirable dust.
Isolated mask is divided into two classes: a kind of use long tube to be connected with the fresh air sources of concentration by respirator；
Another kind is to be connected by the air bottle that respirator carries with user；The isolated mask of both is expensive,
Use is inconvenient for, it is impossible to be widely used in work production.
Filter-type respirator is divided into two classes: one is self-priming filter face mask, i.e. arranges filter course in mask,
The respiratory resistance of this mask is very big, and labourer substantially feels unhappy, breathes arduously, on the other hand after wearing
Filter course effective storage life in mask is the shortest, easily blocks, and needs often to change；Another kind is air-supply
Formula filter face mask, arranges filter course in mask, mask is persistently blown by blowing device, and this mask solves
Respiratory resistance problem, but be the failure to solve filter course and use time short problem.
Utility model content
The technical problems to be solved in the utility model is the filter course of blast type filter face mask of the prior art
Effective storage life is the shortest, needs often to change, and use cost is higher.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of dust-proof breathing of powered supplied air
Device, including containing water or solution, sea in blower fan, sponge filter core, liquid container and respirator, liquid container
Continuous filter element is soaked in water or the solution of liquid container；Air is delivered to respirator by blower fan, and sponge filter core filters
Air.
Further, described powered supplied air dust-proof rebreather also includes splash proof device, described splash proof device
It is sealed on the gas outlet of liquid container, splash proof device is provided with at least one passage, passage
Sectional area is less than the sectional area of gas outlet.
Further, described powered supplied air dust-proof rebreather also includes air filtering cover, and air filtering cover filters and enters
The air of blower fan.
Further, described powered supplied air dust-proof rebreather also includes activated carbon ring, activated carbon ring parcel sponge
Filter element.
Further, the quantity of described liquid container is two, contains dilution heat of sulfuric acid in first liquid container,
Containing alkaline solution in second liquid container, the air that blower fan blows sequentially passes through first liquid container and second
Liquid container.
Further, described powered supplied air dust-proof rebreather also includes casing, described magazine ac blower fan, sky
Air filter cover, first liquid container and second liquid container.
Further, described powered supplied air dust-proof rebreather also includes battery, and battery is that blower fan is powered, battery
It is positioned at casing.
Beneficial effect: (1) this utility model powered supplied air dust-proof rebreather uses sponge filter core to cross in air filtering
Dust, good filtration effect, be not easily blocked；Sponge filter core reinstalls to use after can disassembling cleaning,
Use cost is cheap；Water in liquid container or solution wetted air, improve the breathing comfortableness of wearer.
(2) splash-proof dress it is provided with on the gas outlet of the liquid container of this utility model powered supplied air dust-proof rebreather
Put, it is to avoid the globule enters respirator.(3) this utility model powered supplied air dust-proof rebreather is provided with air filter
Cover filters the air entering blower fan, improves the ability of respiratory organ Chalk-dust filtering further.(4) this practicality is new
Type powered supplied air dust-proof rebreather is provided with activated carbon ring and crosses air filtering, eliminates the unusual smell.(5) this utility model electricity
Dynamic air-feeding dust-proof aspirator is provided with two liquid containers, contains dilution heat of sulfuric acid in first liquid container, the
Containing alkaline solution in two liquid containers, the metallic dust in dilution heat of sulfuric acid dissolved air, in alkaline solution
With the acid droplet in air stream.(6) this utility model powered supplied air dust-proof rebreather is provided with casing
Accommodate each parts of respiratory organ, protect respiratory organ, it is simple to carry.
