Energy circulation device of spraying assembly line

Abstract

The invention discloses an energy circulating device for spraying assembly line, which comprises an airtight casing and a heat-exchange device in the casing, wherein an inner wall of the casing is provided with a heat insulating layer, the heat-exchange device comprises a heat exchanger and a draught fan assembly, and the heat exchanger is provided with a cooling medium inlet pipe and a cooling medium outlet pipe which are communicated with the outer side of the casing. The invention is different with a current high temperature component which is cooled in air after being sprayed and solidified, the energy circulating device leads heat on the surface of the component to transfer to the heat exchanger through air, and then the heat is transferred to a place which needs heat through the cooling medium (water) as agency, for example, the invention provides heat for oil removing, dewatering of a former process on the assembly line, or heats domestic water through an intermediate heat exchanger and the like, thereby environmental heat pollution can be prevented , a large quantity of energy can be saved, and manufacturing cost is reduced.

Description

technical field [0001] The invention relates to an energy circulation device of a spraying production line. Background technique [0002] Spraying production line refers to a production line that covers metal and non-metal surfaces with protective or decorative layers. The quality of spraying not only determines the appearance of the product, but also determines the corrosion resistance and weather resistance of the product. [0003] In the process of painting or plastic spraying, in order to cure the paint or powder spraying, it is usually necessary to heat the workpiece to 150-200°C. After the curing is completed, the workpiece needs to be cooled to room temperature in the air. During this process, a large amount of energy will be lost to the In the atmosphere, it causes thermal pollution of the environment and waste of energy. The previous process of painting or plastic spraying, such as dehydration and water removal, requires a lot of heat. Contents of the invention ...
