DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recovery apparatus for collecting fume dust generated during welding and fusing operations in a plasma fusing apparatus, a YAG laser processing machine or the like.

[0002]

2. Description of the Related Art Conventionally, fume dust generated during welding and fusing work in a plasma fusing apparatus, a YAG laser processing machine, etc., is driven out to the outdoors by natural ventilation without being collected, or an exhaust device installed near a work place. Forcibly exhaust air to the outside. In addition, a large fan-type dust collector is installed covering the entire apparatus such as a plasma fusing apparatus with a cover to collect and collect fume dust.

[0003]

In the case of the natural ventilation described above, sufficient ventilation cannot be obtained and fume dust tends to stay indoors. Even in the case of the exhaust device, a phenomenon occurs in which fumes are not sufficiently collected and drift around the worker, and the working environment cannot be improved to some extent. In addition, in the case of the fan-type dust collecting device attached to a plasma fusing device or the like, a large installation space is required and the entire device is disadvantageously enlarged. Incidentally, fume dust generated during welding and fusing operations is considered to be harmful to the human body, and it is said that if an operator inhales it for a long period of time, it will cause pneumoconiosis. Also,
Fumes generated during fusing of aluminum and stainless steel materials may have an unpleasant odor, which is also undesirable for workers. Therefore, from the viewpoint of the working environment, it is considered to be an important issue to research and develop a recovery device that collects fume dust as much as possible.

[0004] It is an object of the present invention to provide a recovery device for efficiently collecting fume dust generated during welding and fusing operations using a small fume collector unit.

The outlet is directed to the other side of the bed and is arranged so as to face the suction port, and the fume collector unit is operated to clear the outlet from the outlet. Air is blown out toward the suction port to generate a linear air flow, whereby the fume dust immediately after being generated is sucked in from the suction port while being involved in the air flow, and the fume dust is discharged as described above. The filter is configured to be collected by a filter.

According to another aspect of the present invention, a bed for fixing a work is guided by a pair of parallel cross rails below and inside a portal beam having a welding or fusing torch.

The bed is arranged to face the other side of the bed and to face the suction port, and the clean air is blown out of the outlet by the operation of the fume collector unit. And blown toward the 引口 causing linear air flow, thereby sucking fumes dust such immediately after generated from the suction port while caught in air stream,
The fume dust is collected by the filter.

According to a third aspect of the present invention, there is provided the fume dust collecting apparatus in the welding and fusing apparatus according to the first or second aspect, wherein the fume collector unit is sucked from the suction port to the discharge port side. A deodorizing means for adsorbing an unpleasant odor contained in the air thus blown off, and configured to blow out clean air without an unpleasant odor from the outlet.

[0008]

According to the first and second aspects of the present invention, clean air is sucked into the positive displacement blower from the air outlet communicating with the discharge port side of the fume collector unit by operating the positive displacement blower of the fume collector unit. The air is blown toward the suction port communicating with the mouth side to generate a linear air flow. Thus, the fume dust immediately after being generated by welding or fusing is continuously sucked into the suction port while being involved in the air flow. The fume dust sucked together with the surrounding air is separated and collected by a filter of a fume collector unit, and a series of air in which purified air is pumped toward the outlet by a positive displacement blower. Circulating effect. As a result, the fume dusts are efficiently collected by the fume collector unit without substantially diffusing into the surroundings.

According to a third aspect of the present invention, in the case of a recovery device provided with a deodorizing means on the discharge port side of the fume collector unit, an unpleasant odor contained in air sucked from the suction port is absorbed by the deodorizing means. The treated and cleaned air is blown out from the outlet.

According to the apparatus for collecting fume dust in the welding and fusing apparatus, it is possible to efficiently collect fume dust using a fume collector unit including a small-sized, small-volume, positive displacement blower. In addition, this device has the advantage of being small in size, requiring less space for installation in the welding and fusing device.
