A kind of smoke and dust direct discharge type environment-friendly welding auxiliary device

Abstract

The invention provides a smoke directly-discharging type environment-friendly auxiliary welding device. The device comprises a welder, a suction nozzle, a conveying pipe, a smoke filter, an exhaust fan and an energy converter and is characterized in that the energy converter is connected with the welder and the exhaust fan in a controlling mode, fixed to the welder through the suction nozzle, and connected with the suction nozzle and the smoke filter through the conveying pipe, the exhaust fan is directly connected with the smoke filter, the energy converter is an electromagnetic conversion type energy converter, the energy converter and the welder are connected to a power supply in parallel, and the magnetic fielded generated by the power supply of the welder is converted through the energy converter to drive the exhaust fan to work. According to the device, harmful gas and smoke generated by welding are directly discharged through a working point, magnetic field energy generated when the welder works can be utilized to provide exhaust power, extra electric energy does not need to be provided, and therefore exhaust power is obtained and waste energy reutilization is achieved.

Description

technical field [0001] The invention mainly relates to industries such as ships and steel structures, and collects, processes and discharges a large amount of toxic and harmful smoke and gas generated in the welding process. Especially a device suitable for portable operation in limited space. Background technique [0002] Due to the extensive use of welding in the shipbuilding industry, a large amount of toxic and harmful fumes and gases will be generated during the welding process. The existence of these gases not only seriously affects the health of welding workers, but also directly discharges into the air without treatment and will pollute the atmosphere. According to surveys and statistics, in recent years, shipyards have found that a large number of front-line workers suffer from different degrees of pneumoconiosis and other types of occupational diseases caused by toxic fumes and dust. Workers' labor protection articles and improve workers' awareness of protection....

Problems solved by technology

Therefore, manufacturers and shipyards devote their energy to the improvement of equipment, and try their best to develop welding manipulators to reduce manual welding. At the same time, they strive to improve the ventilation of the construction site to ensure the working environment of workers. However, there are many small spaces in the shipbuilding process. and process links, automatic welding equipment cannot be used, and these places are often places where it is very difficult to improve the ventilation condition

The existing welding exhaust equipment on the market is an independent system, it is difficult to ensure the ventilation effect
