Abstract
A device for dustproof gasmask consists of an annir filter 1, an air compression pump 2, a fine-filter 3, a steam storage tank 4, a pressure reducing valve 5, a regulating valve 6 and a mask 9 linked together in order by a connecting pipeline 7, the regulating valve 6 and the mask 9 are linked by a tube 8. The device for dustproof gasmask has good dustproof and antigas effect, and the device is convenient to be used and has low cost. The device in particular fits for long term usage in the work area which has high concentrations of dust as well as poisonous and harmful gases in a certain range.
Description
A kind of dust proof and gas defence mask means belongs to environmental protection technical field, has been specially adapted to high concentrate dust and harmful, toxic gas place.
People are having dirt at present, during the local operation of work under bad environment such as toxic gas, for preventing dirt, poison is to the injury of human body, generally use dustproof, breathing mask, employed now mask mostly adopts filtering type, i.e. filling filtrate in mask, make dirt, poison is absorbed by filtrate, can not enter human body with breathing, this method needs often to change filtrate, otherwise just easily results in blockage or the filtrate inefficacy, and is ineffective, even often change filtrate, pernicious gas and dust also are difficult to guard against fully, still have a certain amount of harmful, toxic gas and dust enter human body, cause the injury to human body.Also have at present and adopt the breathing mask that carries oxygen cylinder, but the use cost height, price is expensive, is not suitable for generally promoting the use of.
The purpose of this utility model be exactly at the invention of the deficiency of said apparatus a kind of dustproof, gas defence is effective, easy to use, the novel dust proof and gas defence mask means that cost is low.Be particularly suitable for the working region high concentrate dust and local long-term use the harmful, toxic gas are arranged within the specific limits.
The technical solution of the utility model is: this dust proof and gas defence mask means is made up of air cleaner 1, pneumatics pump 2, fine filter 3, gas storage tank 4, pressure-reducing valve 5, control valve 6, duct coupling 7, flexible pipe 8 and face shield 9.Air cleaner 1 and pneumatics pump 2 are linked by duct coupling 7; Pneumatics pump 2 and fine filter 3 are linked by duct coupling 7; Fine filter 3 and gas storage tank 4 are linked by duct coupling 7; Gas storage tank 4 and pressure-reducing valve 5 are linked by duct coupling 7; Pressure-reducing valve 5 and control valve 6 are linked by duct coupling 7; Control valve 6 and face shield 9 are linked by flexible pipe 8.Air cleaner must be contained in the place of cleaning of indoor-outdoor air, makes used air source of the gas cleaner like this.The pneumatics pump is selected for use can be according to the pump of gas storage tank internal pressure situation automatic pressure regulation, and the operating pressure of pneumatics pump is 0.2-6Kg, the capacity 〉=150L/min of pneumatics pump.The bigger raising of getting back of quality after air filters through fine filter.The gas-storing capacity of gas storage tank is 1-100L, and its operating pressure is 0.2Kg-6Kg, and the gas-storing capacity size of gas storage tank and operating pressure size are selected for use according to steam transmitting pipe road length and how many decisions of user of service.Pressure-reducing valve reduces to 0.1-0.6Kg to pressure, and output is used then.Control valve can further be regulated the air capacity that enters face shield, makes it to be fit to people's eupnea and uses.Be connected by flexible pipe between control valve and the face shield, can adopt many flexible pipes that control valve and many face shields are linked, can use for many people simultaneously like this, each flexible pipe all directly feeds in the face shield.This mask means can be saved fine filter 3, save fine filter after, pneumatics pump 2 links by duct coupling 7 and gas storage tank 4.Also can save pressure-reducing valve 5 or control valve 6, save pressure-reducing valve after, control valve links by duct coupling and gas storage tank 4, save control valve after, pressure-reducing valve links by flexible pipe 8 and face shield 9.This mask means makes air tentatively filter through air cleaner, and after the supercharging of pneumatics pump, pass through the fine filter secondary filter again, make air purer, this pure air stores through gas storage tank, after the pressure-reducing valve decompression, the air that is adjusted to certain pressure, certain flow through control valve enters face shield and breathes use for people again.
The dust proof and gas defence mask means of said structure is through filter, fine filter secondary filter, dedusting and to remove the toxic effect fruit good especially, and the face shield that connects with flexible pipe can arbitrarily and with the people move, and is easy to use, and available a plurality of mask means are simultaneously for many people's uses, so cost is low.This mask means dust proof and gas defence is effective in a word, and is easy to use, and cost is low, is particularly suitable for being used in the place with high concentrate dust and harmful poisonous gas.
