Abstract

The utility model relates to a labour protection tool, which prevents the fume (primarily comprising manganse, carbon and noxious fine particles) from entering into the human body in welding process. All the time, the general health gauze mask is adopted by welding workers to prevent the fume from entering into the human body, which does not have a good effect on preventing the fume from entering into the human body, and the welding workers feel discomfort and inconvenience. After personal experiences and some experiments, the welding helmet which not only protectes eyes but also prevents the fume from entering into the human body is invented on the existing welding helmet basis. The utility model has the advantages of low cost, convenient operation, no consuming energy and easiness.

Description

Anti-fume welding helmet

This utility model relates to and prevents that the cloud of dust (mainly being particulates emissions such as manganese, carbon) that produces in the welding process from entering the labor protection instrument of human body.

As everyone knows, no matter be alternating current-direct current electric welding (using welding rod); Still in the welding process of carbon dioxide gas arc welding (using welding wire), all will inevitably produce flue dust (mainly being manganese, carbon particulate), these manganese, carbon particulate, the breathing by human body enters the human lung, this not only can influence lung health, and easily suffers from nerve and poison; But, for a long time, the welder enters human body with the flue dust that health gauze mask reduces in the welding process, and this simple appliances for labor protection no doubt play a role, but for the blue-collar welder who produces volume of smoke in the direct contact bonding, actual effect is not good.For example: the welder that summer is soaked with sweat, put on health gauze mask and can feel especially to feel suffocated; The low temperature in severe winter can make the aqueous vapor of exhalation coagulate on mask, and moist mask can make the people feel uncomfortable; When speaking, leaving job site, break etc. in short-term and need take mask, the both hands that stain oil and rust also can make the spoken parts in traditional operas cover stay dirty vestige, and in a word, though this appliances for labor protection of health gauze mask are simple, the welder puts on and be uncomfortable, also inconvenience.

In order to prevent that flue dust from entering human body, be suction clarifying smoke air and adopt XG130-1 type weld fumes clearing machine, this clearing machine, prevent that the cloud of dust from entering human body thereby play.For this reason, the indispensable clearing machine of each welder, every clearing machine is worth more than thousand yuan, and the clearing machine that always will turn round in whole welding process, consumes many electric energy; In addition, every clearing machine will account for certain area, and in welding process, the workman needs translation-angle, also inconvenience during the shift position, and the clearing machine in the running has increased noise; Especially this clearing machine is for pipeline, oil tank, and the interior welds of boiler also can't be carried out.In view of this; this utility model is at the disadvantage of labour protection instrument (articles for use) existence of above-mentioned two kinds of anti-welding flue dust; through on the basis of test of many times; and provide a kind of common welding helmet protection eye functions that both had; can play the dual-purpose preventing dust welding helmet that preventing dust (mainly being manganese, carbon particulate) enters human body again, its advantage is as follows:

The first, producing flue dust and preventing dust, to enter human body be synchronously, begins welding after picking up the preventing dust welding helmet that is:, can accomplish that just preventing dust enters human body in case produce flue dust, and not have uncomfortable feeling; Do not have flue dust when stopping to weld and produce, just can put down the preventing dust welding helmet easily.

The second, by changing filter paper or cloth easily, can guarantee that the flue dust more than 95% is filtered.

Three, changing position and indexing easily at any time in the welding process.

Four, the structure of preventing dust welding helmet only need be transformed on the basis of the existing welding helmet of protecting eyes, and it is simple in structure, and is cheap.

Five, do not need consumes energy.

Preventing dust welding helmet of the present utility model comprises: welding helmet 1, protection glass 2, it is characterized in that: on welding helmet 1, be fixed with rubber mask 3, filter paper or cloth 4, air intake valve 5, air inlet handle 6,

steam vent

7,8,9, rubber washer 10 and clamp nut 11.

Below to the structural representation of exemplary embodiments of the present utility model.

Be described in detail exemplary embodiments of the present utility model with reference to accompanying drawing:

Left hand is held air inlet handle 6, picks up the preventing dust welding helmet, allow rubber mask 3 aim at nose, oral area position, and eyes just in time sees through the protection glass 2 that is fixed on the welding helmet 1, can see the welding position.Connect welding, flue dust constantly is spread out in the surrounding air, enter in the clamp nut 11, the air of band flue dust, through filter paper or cloth 4 filtering smoke, and filter paper or cloth 4 itself are to clamp with rubber washer 10, air inlet handle 6 by threaded end compresses filter paper or cloth 4 with screwing of clamp nut 11, air after the filtration is through the interior pipe of air inlet handle 6, when the people is air-breathing, atmospheric pressure is opened the air intake valve 5 on the rubber mask 3 automatically, so the air after the filtration sucks human body by muzzle.Meanwhile, rubber mask 3 makes

steam vent

7,8,9, all is closed to internal strain under the air-breathing suction of people; When the people breathed, the pressure of breath was closed the air intake valve 5 on the rubber mask 3, and meanwhile, rubber mask 3 outwards distortion is opened

steam vent

7,8,9, discharges gas, thereby finishes the breath cycle of the preventing dust in welding process.When stopping to weld, put down the preventing dust welding helmet at any time.In addition, by the requirement of degree of filtration, needed filter paper or cloth 4 can regularly or irregularly be changed easily, to meet the labour protection requirement.

Claims

Preventing dust welding helmet of the present utility model comprises: welding helmet 1, protection glass 2, it is characterized in that: be fixed with rubber mask 3, filter paper or cloth 4, air intake valve 5, air inlet handle 6, steam vent 7,8,9, rubber washer 10 and clamp nut 11 on welding helmet 1.
