High-efficient forced cooling chamber

Abstract

The invention relates to a high-efficient forced cooling chamber and belongs to the technical field of a coating workshop. The high-efficient forced cooling chamber comprises a forced cooling chamber, an air conditioning unit and an air return fan, wherein the forced cooling chamber is connected with an output end of the air conditioning unit through an air-feeding pipe; the forced cooling chamber is connected with an input end of the air conditioning unit through an air return pipe; the air return fan is arranged on the air return pipe; the air conditioning unit comprises a filtering section and a surface cooling section; the surface cooling section is connected with a return water feeding pipe. The high-efficient forced cooling chamber can achieve the purpose of quickly and cleanly cooling the surface of a workpiece and can achieve the purpose of saving energy of a system by recycling the cold air fed into the equipment.

Description

technical field [0001] The invention belongs to the technical field of painting workshops, and in particular relates to a high-efficiency strong cold room. It is suitable for cooling the workpiece on the coating production line. Background technique [0002] In the coating production line, after the drying furnace equipment heats the workpiece after spraying at high temperature, before entering the next process, a long drying room or air cooling room is usually set up to cool the workpiece. At present, the common cooling section adopts natural Wind cooling, the cooling effect is very poor, and the cooling time and cooling section need to be very long. At the same time, due to the poor cooling effect on the surface of the workpiece, there will be problems such as color difference on the surface of the product after the topcoat is sprayed; it is easy to use natural wind in the workshop It will cause secondary pollution to the workpiece, causing particles on the surface of the...

Problems solved by technology

[0002] In the coating production line, after the drying furnace equipment heats the workpiece after spraying at high temperature, before entering the next process, a long drying room or air cooling room is usually set up to cool the workpiece. At present, the common cooling section adopts natural Wind cooling, the cooling effect is very poor, the cooling time and cooling section need to be very long, and because the cooling effect of the workpiece surface is not good, after the topcoat is sprayed, the product surface will have color difference and other problems; it is easy to use natural wind in the workshop It will cause secondary pollution to the workpiece, causing particles on the surface of the workpiece and other problems that affect product quality; common strong cold room air outlets are located at the bottom and top of the equipment, and the top side returns air, which is likely to cause turbulent flow and transport the lower part of the air. Lubricating oil, dust, etc. are raised and pollute the workpiece; at present, water-cooled air-conditioning units are mostly used, with poor cooling effect, easy to block equipment, one-time use of cold air, and high energy consumption
