The present invention relates to a drying apparatus for powder coating equipment. In detail, by implementing a new drying system that can change the position of the heater up, down, left and right, it can be widely applied to products of various specifications, ultimately powder coating that can improve the drying efficiency and energy efficiency It relates to a drying apparatus of the installation.

In general, powder coating equipment consists of a system for spraying paint on a product to be coated using a spray method, and supplying hot air at an appropriate temperature into a painting booth to dry the coated product.

The operation of the powder coating equipment is as follows.

When the product is put in the painting booth, the painting work is sprayed by automatic gun or worker.

At this time, in order to improve the efficiency of the painting work and to promote natural drying, the inside of the painting booth is accompanied by a process in which outside air is introduced and the inside air is discharged.

When the painting work is completed, the drying process (heat treatment process) for the product is carried out.

The drying operation is carried out by the operation of the hot air supply means. For example, when the circulation fan and the burner (diesel or electric burner) are operated, the air is supplied to the upper part of the booth through the duct while being heated by the burner combustion heat, and then continuously After descending to the bottom to circulate the interior of the product is carried out by the process of being discharged to the outside through the exhaust duct.

On the other hand, in recent years, a far infrared heater is installed in a booth in order to increase the efficiency of the drying operation, and a system for actively drying the product through direct heating of such a far infrared heater has been applied to many trends.

In the case of a conventional drying apparatus using a far-infrared heater, there is a disadvantage in that the applicable range is limited because the heater body is made of a structure fixedly attached to the wall of the booth.

For example, there is a problem that not only the drying efficiency is lowered but also the energy consumption is increased because the heating distance, the heating height, and the heating position cannot be secured for products of various sizes and shapes.

Therefore, the present invention has been devised in view of such a point, and by combining the rotating structure and the slide structure to change the position of the heater means up and down and left and right as necessary, and the optimum heating distance for the product In order to secure the heating height and the heating position, and to implement the configuration driven by easy operation to change the heating distance, height and position, and to maintain the storage condition of the product, The purpose is to provide.
