Tin printing coating iron drying room

Abstract

The invention discloses a tin printing coating iron drying room. The tin printing coating iron drying room comprises a drying room body, wherein the bottom of the inner wall of the drying room body isfixedly connected with a drying room body; a waste heat utilization cavity is formed between the outer wall of the drying room body and the inner wall of the drying room body; the middle position ofthe top of the drying room body fixedly communicates with a gas conveying pipe; one end of the gas conveying pipe communicates with the waste heat utilization cavity; an electromagnetic valve is arranged in the middle of the gas conveying pipe; the lower ends of the two sides of the outer wall of the drying room body fixedly communicate with exhaust pipes; the ends, away from the drying room body,of the exhaust pipes fixedly communicate with exhaust fans; one side of the top of the drying room body fixedly communicates with a first hot air pipe; and one end of the first hot air pipe extends into the drying room body. The invention relates to the technical field of drying rooms. The tin printing coating iron drying room achieves the purpose of secondary utilization of waste heat, reduces the loss of resources, increases the speed of increasing the temperature in the drying room, and reduces the loss of heat.

Description

technical field [0001] The invention relates to the technical field of drying rooms, in particular to an iron printing and coating iron drying room. Background technique [0002] After the pattern is printed on the surface of the metal sheet, it needs to be dried to make the paint adhere closely. Generally, when drying in the drying room, it is heated by hot air circulation. On the one hand, the hot air discharged during the circulation process carries If the waste heat is discharged directly, it will be wasted. On the other hand, the heat exchange between the drying room and the external environment will cause a large amount of heat loss. Both of these are a waste of resources. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the invention provides an iron printing and coating iron drying room, and provides an iron printing and coating iron drying room for secondary utilization of waste heat.

[0002] After the pattern is printed on the surface of the metal sheet, it needs to be dried to make the paint adhere closely. Generally, when drying in the drying room, it is heated by hot air circulation. On the one hand, the hot air discharged during the circulation process carries If the waste heat is discharged directly, it will be wasted. On the other hand, the heat exchange between the drying room and the external environment will lose a lot of heat, both of which are a waste of resources.
