Abstract

The utility model discloses a health care air supply device suitable for special profession comprising a mask and an air clarifier. The air clarifier comprises a filter (7), a refilter (8), a water bath (12), a filling layer (14), a heater (15) and a blower (17). The air which is filtered, refiltered and treated in a water washing mode is dehydrated, made a temperature adjustment and then is sent into the mask of the welder by the blower (17) along a blowing hose (19) for the breathing of the welder during the operation. The lower part and both sides of the mask of the welder are provided with sealed strips to prevent the smoke from entering. The gap on the upper part is used to discharge the exhalant gas and excessive air. The micro-positive pressure condition in the mask can ensure that the air supply is adequate and the smoke can not enter. So, the utility model provides the welding workers engaged in the special profession with an ideal, safe, comfortable and convenient air supply device with health care function.

Description

A kind of health care feeder that is applicable to special work post

One, affiliated technical field

The utility model relates to a kind of special work post health care feeder, especially is applicable to welding worker required health care feeder when weld job.

Two, background technology

During electric welder's operation, because arc temperature is spent up to more than 4000, many metallic elements are evaporated or burn becomes oxide gas.The welder bends over the welding bead top, the flue dust that welding forms is just in time by in the nasal cavity suction body, many dust can be deposited in the lung, part element such as manganese, iron, soluble fluoride etc. then may be dissolved in the blood, have a strong impact on the healthy of welder, then may form mixed pneumoconiosis disease and septicemia in the course of time; For addressing this problem, several devices appearred in past attempts: if any the rubber dust mask of filtering function, fixed smoke ejector and exhaust face shield etc., the former can only elimination part dust and rubber face shield hoop on the face very uncomfortable, make us being difficult to accepting.Fixed smoke ejector is only limited to the smallclothes welding, the position also can't be moved, so also be difficult to apply.The latter is installed getter device additional in face shield, enter flue gas in the face shield with eliminating, but when flue gas is removed in suction, must form little negative pressure in the cover, so make more flue gas enter face shield, makes staff's breathing condition change poorer.Owing to lack hygienic measures preferably, welder's operation at present almost all is under the condition of no any safeguard measure.

Three, summary of the invention

The purpose of this utility model provides a kind of safe, comfortable, feeder that keeps healthy easily, is protected reliably when the operation to guarantee the welder.

The technical scheme that the utility model is taked is, the health care feeder by face shield and air purifier are formed is equipped with the air-distribution pipe in the face shield, and sealing strip is equipped with in face shield bottom and both sides; Air purifier is by filter, filter, water-bath chamber, packing layer, heater, pressure fan are formed again, filter is contained on the cylindrical shell that has universal wheel, the filter again of activated carbon adsorbent and the below that packing layer is installed on filter are housed, the water-bath chamber is located at the below of filter again, the pressure fan that has air outlet is located at cylindrical shell top, the pressure fan below is provided with heater, and cylindrical shell one side is provided with liquid level gauge, and opposite side is provided with overflow pipe.Adopt the utility model, the both sides of welders' mask and below installed soft sealing strip additional, can stop flue gas to enter.At any time be full of face shield and be slight positive pressure state to keep clean air and ajutage is housed in the cover, both can prevent that flue gas from entering, in time discharging the gas of breathing out, it is required to guarantee that again the welder breathes.Clean air is from air purifier.Clarifier is that air is handled the back pressurization, delivered to face shield through air supplying hose through dust filtration, absorption, water washing cleaning, dehydration, temperature adjustment.

Five, specific implementation method

As shown in Figure 1, the utility model is made up of face shield and air purifier, face shield is provided with and protects order glass 5, and air-distribution pipe 3 is housed in the face shield, and sealing strip 4 is equipped with in face shield bottom and both sides, can prevent that flue gas from entering, the gap is left on face shield top, can discharge the gas and the unnecessary air of exhalation, and clean gas passes handle 2 through flexible pipe 19 by the import on the face shield 1 and sends in the face shield through air-distribution pipe 3, be slight positive pressure state in the cover, can not enter to guarantee air feed abundance and flue gas.Air purifier is by filter 7, filter 8, water-bath chamber 12, packing layer 14, heater 15, pressure fan 17 are formed again, filter 7 is contained on the cylindrical shell 6 that has universal wheel 10, the filter again 8 of activated carbon adsorbent and the below that packing layer 14 is installed on filter 7 are housed, water-bath chamber 12 is located at the below of filter 8 again, the pressure fan 17 that has air outlet 18 is located at cylindrical shell 16 tops, pressure fan 17 belows are provided with heater 15, and cylindrical shell 16 1 sides are provided with liquid level gauge 9, and opposite side is provided with overflow pipe 13.Air is under pressure fan 17 attracts, enter in the device through four set filters 7, carry out adsorption treatment by the activated carbon in the filter 8 more then, with filtering toxic gas and peculiar smell, enter water-bath chamber 12 further washing, purifyings through distributor 11 again, dewater with wetting through packing layer 14 heaters 15 then, by pressure fan 17 pressurizations, send in the welders' mask through air supplying hose 19 at last by air outlet 18.

The utility model is simple in structure, protection effect is reliable, and can be with the needs of weld job, shift position at any time, and operation also can obtain fresh, clean gas equally and breathes for the welder in airtight container.One table apparatus can use for the multidigit welder simultaneously simultaneously.Therefore, the utility model provides a kind of desirable safe, comfortable, feeder easily with health care for the welding worker of special work post.
