The invention provides a heat recycling system in welding wire production. The heat recycling system comprises a waste hot water pond, a cooling water pond, a heat pump unit, a cleaning tank and a liquid tank. The waste hot water pond is connected with a pretreatment device which comprises a first settling pond and a second settling pond; a third hot water pipe is arranged between the first settling pond and the second settling pond, and a fourth hot water pipe is connected between the second settling pond and the waste hot water pond; a water inlet pipe is arranged on the first settling pond; a heat exchange coil pipe is arranged in the cleaning tank, pipe segments at the two ends of the heat exchange coil pipe are parallel and are vertically arranged, and the middle pipe segment is horizontally and spirally provided with a plurality of layers of rectangular structures on the upper portion, the lower portion, the inside and the outside. According to the heat recycling system in welding wire production, heat in the waste hot water pond in production is absorbed through the heat pump unit, the heat is transferred to the cleaning tank, the heat exchange coil pipe is indirectly heated to heat liquid in the liquid tank, and heating efficiency is high.
Description
technical field [0001] The invention belongs to the field of welding wire production, and in particular relates to a heat recovery and utilization system in welding wire production. Background technique [0002] In the welding wire production process, the electroless copper plating process is a very important production process, which is directly related to the quality of the welding wire. In processes such as electroless copper plating, it is necessary to add a large amount of heated chemical substances to process the wire. At present, coal and natural gas are mostly used as heat energy for heating chemical substances, which not only has an impact on the environment but also has high input costs. Contents of the invention [0003] In view of this, the present invention aims to propose a heat recovery and utilization system in welding wire production to solve the problem of using coal and natural gas to heat the solution in the current welding wire production process such...
