Abstract
The utility model discloses a wet-type anti-dust respirator which comprises a respiratory chamber and a filter tank, wherein, the filter tank is connected with the underside of the respiratory chamber, and a filter layer is arranged in the filter tank; an air inlet and an air outlet are arranged on the respiratory chamber, the air inlet is communicated with the filter tank through a one-way valve, and the air outlet is communicated with the outside through another one-way valve. The wet-type anti-dust respirator is characterized in that the filter layer in the filer tank is composed of water, wet sponge, activated carbon and sponge, and an air inlet pipe which is arranged on the filter tank is communicated with the bottom of the filter tank. When the wet-type anti-dust respirator is in use, the face mask of the respiratory chamber is buckled on the mouth and the nose of a user, and air with dust and harmful substances enters the filter tank through the air inlet pipe inserted in the bottom of the filter tank so that the filtering of the air is finished through the water, the wet sponge, the activated carbon and the sponge, and the clean air enters the respiratory chamber through the air inlet for a person to use. The utility model has simple structure and convenient use, can effectively prevent dryness, dust and harmful gases from hurting human bodies, and has a protective function to the user.
Description
One, technical field
The utility model belongs to labour protection security protection facility, is specifically related to a kind of anti-dust respirator.
Two, background technology
A lot of industries (as cement manufacturing, ore pulverize, the abrasive dust of the various raw materials of industry etc.) site for labour all have air drying, the excessive problem of dust, some pernicious gases of also existence that have.And existing anti-dust respirator all is made up of filter paper, sponge, filter cloth, is difficult to solve the problem of air drying and filtering dust and pernicious gas, causes very big injury to the staff.
Three, summary of the invention
The purpose of this utility model provides that a kind of to collect dustproof and gas defence be the wet type anti-dust respirator of one, and it can prevent the infringement to human body of air drying, dust and pernicious gas effectively.The technical solution adopted in the utility model is: the wet type anti-dust respirator comprises respiratory chamber and filtering tank, and filter course is housed in filtering tank; Air inlet and gas outlet are arranged on the respiratory chamber, and its air inlet communicates with filtering tank through sucking check valve, and the gas outlet communicates with the external world through the exhalation check valve, and filter course is water, Mare Humorum cotton, activated carbon and sponge, have air inlet pipe to lead to jar on the filtering tank at the bottom of.During use, the face shield of respiratory chamber is buckled on user's mouth and nose, the gas that has dust and harmful substance enters filtering tank by the air inlet pipe of inserting jar end, finish filtration through water, Mare Humorum cotton, activated carbon and sponge, pure air enters respiratory chamber by suction inlet and uses for the people, and breath is discharged by the gas outlet.
Filtered out behind airborne dust and pernicious gas the multiple filtration, reached with the humid air, pure and fresh filter effect through water, Mare Humorum cotton, activated carbon and sponge.
The utility model is simple in structure easy to use, can prevent the injury to human body of drying, dust and pernicious gas effectively, and the user is played a protective role.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Five, the specific embodiment
The utility model comprises respiratory chamber 1 and filtering tank 2, and the front openings of respiratory chamber 1 is the face shield that has sealing ring.The filter course of packing in the filtering tank 2 is followed successively by water 4, Mare Humorum cotton 5, activated carbon 6 and sponge 7 from bottom to up.During use, the air that has dust and a pernicious gas enters the jar end of filtering tank 2 by the air inlet pipe 3 of inserting jar end, through finishing filtration behind water 4, Mare Humorum cotton 5, activated carbon 6 and the sponge 7, enters respiratory chamber 1 by air entry 8 and uses for the people.
Face shield is buckled on the mouth and nose during use, sucks check valve 9 and open when the user is air-breathing, and exhalation check valve 10 is closed, and the gas after the filtration enters respiratory chamber 1 by filtering tank 1 by air entry 8; When the user exhales, suck check valve 9 and close, exhalation check valve 10 is opened, and the carbon dioxide that the people breathes out is discharged by gas outlet 11.
