Closed cooling tower cooling device for forging and stamping industries

Abstract

The invention relates to a closed cooling tower cooling device for forging and stamping industries. A coil is fixed on a support, an air inlet grill is arranged on a closed cooling tower, a cold oil outlet is formed in one end of the coil, a hot oil inlet is formed in the other end of the coil, a cold oil pipe is connected between the cold oil outlet and the inlet end of an oil tank, a hot oil pipe is connected between the outlet end of the oil tank and the hot oil inlet, a water collection tank is fixed in the closed cooling tower, a sewage drainage valve is arranged at the bottom of the water collection tank, an overflow valve and a water replenishing valve are arranged on the water collection tank, spraying fillers are arranged in the closed cooling tower, a bulk water disk is arranged in the closed cooling tower, the inlet end of the bulk water disk is connected with a spraying pipe, a spraying pump is arranged on the spraying pipe, and a fan is positioned at the top end of the closed cooling tower. Work oil of the closed cooling tower cooling device is cooled in a closed cycle mode, oil and water are separated, and oil leakage and oil-water streaming are avoided. The closed cooling tower cooling device improves production efficiency, saves water and reduces power consumption.

Description

technical field [0001] The invention relates to a cooling device for the forging industry, in particular to a closed cooling tower cooling device for the forging industry. Background technique [0002] At present, the temperature of the working oil used in domestic hydraulic machines and hydraulic hammers (electro-hydraulic hammers) will rise to above 50°C after several cycles, which will seriously affect the sealing performance of the equipment and make the forging equipment unable to operate, and the seals will quickly Damage, frequent replacement of seals, affecting production, in order to cool the working oil, in order to cool the working oil, the plate heat exchanger was originally used for indirect cooling with tap water, river water or groundwater. This original cooling method is difficult to achieve the ideal cooling effect, and After long-term use, the cooling fins of the heat exchanger are easily oxidized by high-temperature oil, resulting in oil leakage and oil-wa...

[0002] At present, the temperature of the working oil used in domestic hydraulic machines and hydraulic hammers (electro-hydraulic hammers) will rise to above 50°C after several cycles, which will seriously affect the sealing performance of the equipment and make the forging equipment unable to operate, and the seals will quickly Damage, frequent replacement of seals, affecting production, in order to cool the working oil, in order to cool the working oil, the plate heat exchanger was originally used for indirect cooling with tap water, river water or groundwater. This original cooling method is difficult to achieve the ideal cooling effect, and After long-term use, the cooling fins of the heat exchanger are easily oxidized by high-temperature oil, resulting in oil leakage and oil-water flow

At the same time, the waste of water resources is huge

Refrigerators are also used for cooling. This kind of equipment is expensive and consumes a lot of power.
