Description

A wearable welding fume purification device

technical field

The utility model relates to a purification device, in particular to a wearable welding fume purification device.

Background technique

Welding fumes are solid particles and harmful gases produced by welding operations in the factory production process, which can float in the air for a long time. It is an important occupational disease hazard factor that pollutes the working environment and damages the health of workers, and can cause a variety of occupational lung diseases including pneumoconiosis. In recent years, more and more attention has been paid to the control of welding fume.

General welding fumes and harmful gases are controlled by comprehensive ventilation and local exhaust in the way of control. Comprehensive ventilation is to use clean air to dilute the concentration of harmful substances in the indoor air, and at the same time continuously discharge the polluted air to the outside or collect and purify it. Local exhaust is to control the local air flow, so that the local workplace will not be polluted by harmful substances and maintain a good air environment.

Among them, local exhaust can be divided into fixed local exhaust system and mobile local exhaust system according to different gas collection methods. The fixed local exhaust system is mainly used in large-scale welding production workshops with fixed operating locations and workers' operating methods. The position of the air collecting hood can be fixed at one time according to the actual situation. The working position of this kind of exhaust system is not flexible, and the application range is narrow. The working state of the mobile local exhaust system is relatively flexible, and different working postures can be adopted according to different working conditions to ensure processing efficiency and operator convenience. In order to achieve better welding fume control effect and further improve the working environment, a more flexible and convenient welding fume purification device with high dust removal efficiency and low energy consumption is needed.

A supporting orifice is arranged in the adsorption box, and the filter element is placed on the supporting orifice.

The filter element is composed of a non-woven fabric layer, an activated carbon fiber layer and a high-efficiency air filter net laid in sequence.

The air collecting hood is connected with the safety helmet through a mechanical arm.

An air outlet is provided at the bottom of the adsorption box, and the air outlet communicates with the air outlet of the vortex fan.

A 12V DC power supply is arranged in the adsorption box, and a switch is arranged on one side of the adsorption box, and the switch is arranged on the circuit formed by the 12V DC power supply and the eddy current fan.

The suction box is provided with straps.

The sealing cover is connected to the adsorption box through an easy-to-open and close buckle.

Due to the adoption of the above technical scheme, the utility model has the following advantages: 1. The utility model combines the filter equipment based on the adsorption box with a safety helmet and a welding mask to design a wearable welding fume purification device, which is more flexible in use ,convenient. 2. There is a mechanical arm between the gas collecting hood and the safety helmet of the utility model, which is convenient for adjusting the direction of the gas collecting hood. Therefore, when in use, the gas collecting hood can be adjusted to face the working solder joint, so that the concentration of the intake air is greatly improved. Reduce the amount of circulating air, thereby saving energy and improving dust removal efficiency. 3. The utility model uses a 12V DC power supply and a small high-negative-pressure vortex fan as the airflow driving source of the adsorption box, which can effectively reduce the volume and weight of the device and greatly enhance portability. 4. The utility model adopts a backpack design, and a strap is arranged on the adsorption box, so it is easy to wear.
