Integrated strong cold room

Abstract

The invention relates to an integrated forced cooling room, and belongs to the technical field of coating workshops. The integrated forced cooling room comprises a forced cooling room body and an air returning fan, wherein an air supplying area and an air returning area are arranged in the forced cooling room body; the output end of the air returning fan is connected with the air supplying area through an air supplying pipe; the input end of the air returning fan is connected with the air returning area through an air returning pipe; a surface air cooler is arranged in the air returning area and is connected with a return water supplying pipeline; and the return water supplying pipeline is arranged on the outside of the forced cooling room body. A cooling system is arranged in the forced cooling room; and by the design of the integrated forced cooling room, the space is saved, the energy consumption is reduced, and the investment cost is saved. The forced cooling room is in a cold air circulating refrigerating mode to cool down surfaces of workpieces, the purpose of quickly reducing the temperature is achieved, and cold air supplied into equipment is recycled so as to save energy.

Description

technical field [0001] The invention belongs to the technical field of painting workshops, and relates to a built-in cooling system in a strong cold room, in particular to an integrated strong cold room. Background technique [0002] In the coating production line, the forced cooling room after the drying furnace often uses natural wind cooling or water-cooled air-conditioning units to produce cold air cooling, the cooling effect is poor, the cooling time and cooling section need to be very long, and because the cooling effect of the workpiece surface is not good, and As a result, after the topcoat is sprayed, problems such as color difference will appear on the surface of the product; the use of natural wind in the workshop is likely to cause secondary pollution to the workpiece, causing particles on the surface of the workpiece and other problems that affect product quality; the common strong cold room tuyere At the bottom and top of the equipment, the return air on the to...

Problems solved by technology

[0002] In the coating production line, the forced cooling room after the drying furnace often uses natural wind cooling or water-cooled air-conditioning units to produce cold air cooling, the cooling effect is poor, the cooling time and cooling section need to be very long, and because the cooling effect of the workpiece surface is not good, and As a result, after the topcoat is sprayed, problems such as color difference will appear on the surface of the product; the use of natural wind in the workshop is likely to cause secondary pollution to the workpiece, causing particles on the surface of the workpiece and other problems that affect product quality; the common strong cold room tuyere At the bottom and top of the equipment, the return air on the top side is likely to cause turbulent flow, which will raise the lubricating oil and dust in the lower part, causing pollution to the workpiece; the water-cooled air conditioning unit is adopted, and the cold air is used for one time, which consumes a lot of energy. ;The cooling system is external, and an external air-conditioning unit is required, which requires an increase in floor area, increases the difficulty of retrofitting existing equipment, needs to set a long return air duct, increases energy loss, increases air-conditioning equipment, and increases investment costs
