The pipe is used as a material for manufacturing the pipe fitting, and the quality of the pipe directly determines the quality of the pipe fitting. Such pipes are used in building engineering, automobile industry, power plant, chemical plant, etc.

In a pipe heat treatment production line, the inner wall of a quenched pipe generally accumulates water, the accumulated water in the pipe is not easy to drain in the normal running process of the pipe, and if the accumulated water is not drained in time, the inner wall is dried, so that the problems that a conveying roller way is rusted, machinery in a tempering furnace is corroded, the tempering effect is influenced and the like are caused.

The traditional drainage mode is through the passageway heat treatment to tubular product, but tubular product length is up to about 6 meters, and the heat can't evenly conduct on the wall of passageway in the tubular product, leads to this kind of mode drainage speed slower. And at present, some drainage modes of blowing through the air pump appear in the market, but it is relatively poor with the assembly line matching nature at this kind of device, the material loading process and the unloading process of tubular product can't realize automatically, still need manual operation to go on, can't realize automatic fast operation, and the material loading process and the time of unloading cost of tubular product are longer, through the experiment, it is slightly slow (pile tubular product one pile with tubular product) to weather tubular product than the manual operation air pump, the manual work only need tubular product one side of piling to hold the trachea of air pump blow to the hollow part of tubular product can), these two kinds of modes that utilize the air pump to weather tubular product have influenced the drying time of tubular product inner wall to a certain extent, lead to the process time to increase, influence the production rhythm.
