Abstract
The antidusting and anti-poisoning wet mast is composed of mask, filtering box and filtering material. Said filtering box full of filtering material having strong adsorption action is connected to mask. It has a single channel for both inspiration and expiration, so featuring simple structure.
Description
The present invention relates to a kind of dustproof, anti-poison respirator, particularly a kind of being applicable at a kind of mouth mask work of silicious dust operation place and that spray insecticide personnel's frenulum belongs to the labour protection field.
About 1,000 ten thousand people of workman of present whole nation contact dust work, whole nation accumulative total pneumoconiosis patients was people more than 470,000 in 92 years, and in vast rural area, cause that because of spraying organophosphorus pesticide the situation of poisoning is also very serious every year.Country once always protected (81) No. 46 literary composition regulations of word " must not provide cotton cloth respirator in silicious dust operation place " in 81 years with Lao for this reason.Tool is understood, and homemade anti-dust respirator has two kinds: one, simple cotton cloth respirator; Two, synthetic fibers Filter membrane mask; Homemade anti-poison respirator is a kind of: its filtrate is an active carbon.
One, the cotton cloth respirator dust proof rate is low, and service life is short.
Though two, synthetic fibers Filter membrane mask dust collection efficiency is better, dust-loaded limited in one's ability, resistance is big, under the situation especially higher in dust concentration, that surrounding air humidity is bigger, can not use for a long time.
Three, with the activated carbon be the anti-poison respirator of filtrate, its filtrate is disposable use.Resistance is big, cost is high, the gas defence effect is not ideal.
External anti-dust respirator good looking appearance, technology are meticulous, and pendant carries comfortable, but its filter membrane box and filter membrane are disposable use, cost an arm and a leg.
The objective of the invention is to develop a kind of antidusting and anti-poisoning mask, adding different antidotes when being used for gas defence can play detoxication to different poisonous substances, and filtrate is reusable, and cheap.
Solution of the present invention is achieved in that
The filtrate jar (6) of ining succession in the below of face shield (1), filtrate in the filtrate jar (6) is a sorghum knot flesh, adding different detoxicating liquids in sorghum knot flesh can detoxify to different poisonous substances, there is base (10) lower end of filtrate jar (6), the uniform mesh that is of a size of the 3-5 millimeter in the bottom surface of this base (10).
The both sides of face shield (1) respectively have a pair of junction button (2) to be used to connect frenulum (3), and this junction button is fixed on the face shield with fixed axis (4), and face shield (1) is connected with spiral shell nurse (5) with filtrate jar (6).
For preventing that filtrate (9) from moving and appearing, and guarantee that air is unobstructed, respectively there is the diameter barrier (7) identical with the internal diameter of filtrate jar (6) bottom at filtrate (9) with the top, respectively has a bed thickness to be about 3 millimeters sponge (8) above the barrier with following below last barrier.
Because filtrate adopts the sorghum flesh, add water and can adsorb a large amount of dust after moistening; Add in water and can play detoxication again after antidote is made into the moistening filtrate of saturated solution, the characteristics of sorghum flesh are not only can strengthen absorption property after soaking and not influence gas permeability, can reuse for a long time.Should be dustproof, anti-poison respirator not only can be used for being engaged in the dustproof of dust work personnel, can be used for the detoxifcation of various poisonous substances after adding different antidotes again, this mouth mask for exhale, air-breathing single channel, thereby reduced respiratory resistance, reduced cost.

The contrast accompanying drawing further describes below:
The present invention is made up of face shield and filtrate jar two large divisions.Face shield is made of nontoxic rubber, and the flexibility that is half cone type and skin of face contact site designs according to " Chinese adult standard head model ".Respectively there is a pair of fixed axis (4) the face shield both sides, are used for by dress junction button (2), and four junction buttons (2) respectively connect a frenulum.It is 40 millimeters hole, garden that diameter is arranged in center, the below of face shield (2), with suitable for reading the communicating of filtrate jar (6), use spiral shell nurse (5) that filtrate jar (6) is firmly linked to each other with face shield (1) herein, exhale like this, air-breathingly have only a passage, simplify the structure, reduced respiratory resistance.The base (10) of filtrate jar (6) and tank body are for being threaded the uniform mesh that is of a size of the 3-5 millimeter in the bottom surface of base (10).
The identical barrier (7) of internal diameter that one diameter and filtrate jar (6) are respectively arranged at the bottom of filtrate (9) and top.Down above the barrier and last barrier below respectively have a bed thickness to be about 3 millimeters sponge (8), be filled with sorghum flesh as filtrate in the centre of this two-layer sponge.
When being used for preventing dust, at first the filtrate in the filtrate jar (6) is soaked with clear water, get rid of redundant moisture, can use.Wash down with clear water with the back, be put in the ventilation.
When being used for gas defence, available saturated saleratus liquid (sodium acid carbonate) soaks into, and gets rid of unnecessary saleratus liquid and can use, and rinses well with the back water, is put in the ventilation.
Claims (3)
1, dustproof, the anti-poison respirator of wet type, it is characterized in that: the filtrate jar (6) of ining succession in the below of face shield (1), filtrate (9) in the filtrate jar (6) is the sorghum flesh, and there is base (10) lower end of filtrate jar (6), the uniform mesh that is of a size of the 3-5 millimeter in the bottom surface of this base (10).
2, according to said dustproof, the anti-poison respirator of claim 1, it is characterized in that: face shield (1) is made of nontoxic rubber, and respectively there is a pair of junction button (3) its both sides, and face shield (1) is connected by spiral shell nurse (5) with filtrate jar (6).
3, according to claim 1 or 2 said dustproof, anti-poison respirators, it is characterized in that: the diameter barrier (7) identical with the internal diameter of filtrate jar (6) respectively arranged at the bottom and the top of filtrate, below last barrier, respectively have a bed thickness to be about 3 millimeters sponge (9) above the barrier with following.
