Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a stand and manufacturing method of an after-

The present invention relates to a stand for supporting and protecting an aftercooler used in an air dryer, and a manufacturing method thereof.

Generally, an air dryer system is an air supply system for dehumidifying compressed air generated from a compressor to be used in a system requiring clean compressed air in electric, electronic, medical, pharmaceutical, food, chemical, and semiconductor processing.

Such an air dryer system includes a compressor for generating compressed air, a filter for filtering foreign substances in the compressed air generated by such a compressor, an air dryer for removing moisture in the air, and the like.

On the other hand, the compressor sucks air in the air and compresses it to a high pressure and then discharges the compressed air to an industrial site. When the air is compressed to a high pressure, the temperature rises to a high temperature. The life and function of the production line and various pneumatic devices may be deteriorated, which may result in fatal consequences for productivity and quality.

Accordingly, it is necessary to lower the air temperature of the compressor to condense and dissolve it, to remove moisture and to dry the air, and the condensed water generated in this process is discharged to the outside through an air dryer or a filter.

The air dryer system can be divided into an adsorption type and a freezing type. In the case of the refrigerated type, after the compressed air is cooled through the aftercooler, the dust and the like are removed through the main filter, moisture is removed through the heat exchange device, Thereafter, foreign matter and moisture are additionally removed through the line filter and the air filter, and the clean air is supplied to the necessary system.

On the other hand, the heat exchanger includes a compressor for compressing the gas refrigerant, a hot gas bypass valve for controlling the load, a filter dryer for removing impurities, a capillary for swelling the liquid refrigerant exiting the condenser, A heat exchanger for performing dehumidification of the compressed air due to heat exchange with hot and humid compressed air passing through the inside through the latent heat of evaporation of the refrigerant, and a drain device for discharging the condensed water generated through cooling of the high- .

The aftercooler used in such an air dryer system may be installed integrally or separately with the heat exchanger, and a stand for maintaining a predetermined height from the installation floor may be applied.

However, in the conventional stand, since the base plate on which the components making up the aftercooler are placed and the legs provided on both sides of the base plate are welded to each other so that the base plate can have a predetermined height from the bottom surface of the base plate, It is necessary to separately manufacture the base plate and the leg and to weld the base plate and the leg, and thereafter, coating is performed for the surface treatment of the welded portion and the corrosion prevention, which is complicated and costly to manufacture.

Further comprising at least one third reinforcing member for connecting the front and rear side reinforcing portions of the base portion to each other in a rectangular or inclined form with respect to the longitudinal direction of the base portion. The method according to claim 1,
Wherein the base is provided with a casing having a bottom surface and front and rear surfaces opened, both side surfaces and an upper surface being integrally or assembled, and the front and rear surfaces being opened and closed by a lid. 9. The method of claim 8,
Wherein a part of both sides of the casing extends downward, and the extended portions thereof are overlapped on both side surfaces of the leg portion, and the overlapped portions are coupled through the fastening member. A method of manufacturing a stand of an aftercooler according to any one of claims 1 to 3,
The reinforcing portions located on the front and rear surfaces of the base portion are first folded inwardly at 90 degrees using the second folding line and then folded inward at 90 degrees using the folding line 2-2, Folding 90 degrees three times inward by using a 2-1 folding line, and then folding the folded line inward by 90 degrees in a fourth step using the second folding line;
The extended portions located on the front and rear sides of the leg portion are first folded inwardly at 90 degrees using the first to fourth folding lines and then folded inwardly at 90 degrees using the folded first to third folding lines, A third step of folding inward by 90 degrees three times using the folding line 1-2 and then folding inwardly by 90 degrees in the fourth step using the folding line 1-1; And
A third step of bending the leg part 90 degrees inward by using the first folding line;
Wherein the step of assembling the stand includes the step of forming the stand of the after cooler. 11. The method of claim 10,
Each of the pair of first reinforcing members bent at a right angle by the third folding line is connected to the bottom surface of the reinforcing portion located at both sides of the base portion and the side surface of the extending portion adjacent to the base portion, Wherein the step of forming the stand comprises the steps of: 11. The method of claim 10,
Folded inwardly 90 degrees inside by the 4-1 folding line inside the folded extension portion, folded 90 degrees inside 90 degrees by the 4-2 folding line, and then folded inward by the 4-3 folding line Further comprising a step of inserting the second reinforcing member, which is formed by folding the third angle by 90 degrees, through a direct coupling screw that is fastened to the inside of the extended portion from the lower both sides of the side of the leg portion . 11. The method of claim 10,
Wherein the casing has a bottom surface and front and back surfaces opened on the top surface of the base and both sides and an upper surface are laid, and a portion extending downward from both sides of the casing is overlapped on both sides of the leg portion, And a step of fastening the bracket to the bracket.
