DETAILED DESCRIPTION

[0023] To make the objectives, technical solutions and advantages of the present application clearer, the present application will be described in further detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] It is understood that the above description is only exemplary and is not intended to limit the scope of the present application.

[0025] The specific embodiments of the present application will be described below with reference to the accompanying drawings. Figures 1-5 Some embodiments of the present application provide a smoke-free protective manual arc welding machine.

[0026] In one embodiment of the present application, a smoke-free protective manual arc welding machine is provided. The device includes a welding machine head 100, an exhaust fan 200, a gas turbine shell 300 and a smoke exhaust pipe group 400, wherein the smoke exhaust pipe group 400 is fixed to the surface of the welding machine head 100, and the bottom end is provided with an air inlet 410 opposite to the arc end of the welding machine head 100. In this structure, the gas turbine shell 300 is fixedly connected to the top surface of the smoke exhaust pipe group 400, and is in communication with the surface of the exhaust fan 200 through the air inlet end. The exhaust fan 200 includes a wind pipe 210, a motor pipe 220 and an impeller 230, wherein the surface of the motor pipe 220 is provided with a rectifier plate 221 to be fixed to the inner side of the wind pipe 210. One side of the wind pipe 210 is provided with an air inlet hopper 211 in communication with the inner side of the gas turbine shell 300, and the other end of the air inlet hopper 211 is connected to the port of the impeller 230, so as to guide the airflow.

[0027] In this embodiment, the airflow generated by the exhaust fan 200 enters the inner side of the wind pipe 210 from the gas turbine shell 300 and is discharged through the impeller 230, while the effective discharge of the flue gas is realized in the smoke exhaust pipe group 400. By using the double flue structure of the smoke exhaust pipe group 400 and the air inlet 410, the accumulation of welding flue gas is effectively avoided, and the cleanliness of the welding environment is ensured. In addition, the heat dissipation guide cavity 110 and the air inlet fan 120 are symmetrically arranged on both sides of the welding machine head 100, the flow path of the airflow is optimized by the rectifier fin 111, the temperature of the airflow is increased by using the heat generated by the welding machine, and the condensation of the flue gas in the smoke exhaust passage is prevented.

[0028] In another embodiment, the smokeless protection type manual arc welding machine further comprises a smoke purification system on the basis of the above structure. The smoke purification system is composed of multiple components, including a filtering component, a condensing component, an adsorbing component and an exhaust component, which are used for multi-stage purification of welding smoke. The filtering component is installed at the inlet of the air duct 210 to remove large particle impurities; the condensing component is connected between the air inlet hopper 211 and the impeller 230 to condense part of harmful substances by reducing the temperature of the smoke; the adsorbing component is installed behind the impeller 230 to adsorb and purify the remaining harmful gases by using activated carbon materials; finally, the purified smoke is discharged through the exhaust component.

[0029] In this embodiment, the multi-layer purification of welding smoke is achieved by the above-mentioned smoke purification system, which greatly reduces the pollution of the welding environment. At the same time, the motor cylinder 220 drives the impeller 230 to rotate at high speed, so that the airflow enters the air duct 210 through the air turbine shell 300 and is accelerated out through the impeller 230, thereby ensuring the exhaust efficiency of the purification system. In addition, the hot air generated by the equipment during operation is introduced into the smoke exhaust channel through the heat dissipation guide cavity 110 and the air inlet fan 120 components on both sides of the welding machine head 100, so that the smoke is discharged more smoothly, avoiding the formation of condensation, and further improving the smoke exhaust effect.

[0030] In another embodiment, the utility model also contains a wind speed monitoring system for further optimizing the smoke exhaust effect. The system is provided with a wind speed sensor on the surface of the welding end of the welding machine head 100 to monitor the airflow speed at the bottom end of the heat dissipation guide cavity 110 and the port airflow speed at the air inlet 410. By controlling the power of the exhaust fan 200, a stronger airflow than the air inlet fan 120 is generated to effectively guide the smoke into the smoke exhaust cylinder group 400 and discharge it through the air inlet 410, ensuring the stability of smokeless operation.
