Abstract
The utility model belongs to the field of surface treatment, and particularly relates to a device for drying moisture on the surface of a part. The device comprises: heat exchange tubes, hot water tanks; the heat exchange pipe is arranged in the hot water tank and is immersed in the hot water tank, so that the compressed air enters from the compressed air inlet of the heat exchange pipe, and the compressed air and the hot water exchange heat to obtain hot compressed air which is discharged from the compressed air outlet. The utility model can effectively solve the problems that normal-temperature compressed air is difficult to completely blow water on the surface of the part for a long time due to low environmental temperature during production in winter, large-area watermarks are left, and the requirements on appearance quality are not met.
Description
Technical Field
The utility model belongs to the field of surface treatment, and particularly relates to a device for drying moisture on the surface of a part.
Background
The existing surface treatment production line adopts normal-temperature compressed air to blow dry moisture on the surface of a part, but when the temperature is lower in winter, the moisture evaporation effect is weakened, the compressed air adopting normal temperature is difficult to blow dry the moisture on the surface of the part for a long time, large-area watermarks are left on the surface of the part, and the requirement of acceptance check of the appearance quality is not met.
SUMMERY OF THE UTILITY MODEL
The purpose of the utility model is: the utility model provides a device for weathering part surface moisture can be when winter ambient temperature is lower, can weather part surface moisture fast, improves work efficiency, can ensure again to weather the back and do not leave obvious watermark on the part surface to accord with appearance quality and check and accept the requirement.
The technical scheme of the utility model is as follows:
there is provided an apparatus for blow drying moisture on a surface of a part, comprising: heat exchange tubes, hot water tanks;
the heat exchange pipe is arranged in the hot water tank and is submerged in the hot water tank, so that compressed air can enter from a compressed air inlet of the heat exchange pipe, the compressed air and the hot water are subjected to heat exchange to obtain hot compressed air, and the hot compressed air is discharged from a compressed air outlet.
The heat exchange tube in the hot water tank has a snake-shaped structure.
A hot steam pipe is arranged in the hot water tank; the hot steam pipe is used for heating water in the hot water tank.
The hot steam pressure of the hot steam tube is: 0.6 to 1 MPa; the temperature is as follows: 100 to 110 ℃.
The working pressure of the compressed air inlet is as follows: 0.8 to 1.2 MPa; the temperature was room temperature.
The working pressure of the compressed air outlet is as follows: 1.2-1.6 MPa; the working temperature is as follows: 80-90 ℃.
The utility model has the advantages that: the hot steam is introduced into the hot water tank to heat the tank liquor, and meanwhile, the compressed air is introduced into the heat exchange pipe to realize full and uniform preheating, so that the problem that the tank liquor remained in part of part holes in winter is not completely blown by freezing to cause corrosion is effectively solved, and the quality of the product is not guaranteed.
