Abstract
The invention provides a quenching oil cooling device of a vacuum oil quenching furnace, which is a cooling device of quenching oil used for heat treatment, and can expedite the cooling velocity of a workpiece and improve the permeability of the workpiece. The heat treatment process has a certain demand on the temperature of quenching oil, and too high temperature of quenching oil will directly influence the quality of the quenching workpiece. Currently, an oil groove of the vacuum quenching furnace is provided with a heating device, but generally the cooling to oil relies on an oil agitation impeller, because the oil temperature will rise rapidly in the continuous operation of the vacuum furnace, and the oil is in the closed state, the cooling velocity in the operation process is inadequate, thereby causing poor product quality. The cooling device mainly changes an oil agitation structure of the original vacuum furnace into a cooler structure, an oil outlet is arranged above an oil box, and an oil inlet is disposed below the oil box, and the heated oil is pumped into a heat exchanger by a pump through the oil outlet. A fan blows heating fins to take away heat, thereby achieving the purpose of fast heat exchange. The cooling device solves the difficult problem of inadequate heat exchange speed before.
Description
Technical field:
The present invention is a kind of refrigerating unit of thermal treatment with quenching oil, and it can accelerate the speed of cooling of workpiece, improves the perviousness of workpiece.
Background technology:
Thermal treatment process has certain requirement to the temperature of quenching oil, and the too high meeting of quenching oil temperature directly influences the quality of quenching workpiece.The oil groove of vacuum quencher has heating unit at present, but the cooling of usually oil realizes by oily paddle wheel, because vacuum oven is in the process of working continuously, the oil temperature can rise rapidly, and oil is at closed state, and the speed of cooling of working in operation process is not enough to making.Thereby cause poor product quality.
Summary of the invention:
The present invention mainly changes the oily whipped-up structure of former vacuum oven into cooler construction, opens an oil outlet above fuel tank, below open an oil-in, its heated oil by oil outlet by in the pump suction interchanger.Blowing to the heating fin by blower fan takes away heat.Thereby reach the purpose of quick heat exchange.This equipment is simple and effective, takes up an area of for a short time, is worthy to be popularized.
Specific implementation method:
This installs by the pipeline oil strainer, pump, and interchanger, and motor and impeller are formed.Interchanger is connected with ventilated machine, is that wind directly blows on heat exchanger fin and lowers the temperature, and the front end of oil-in is an oil strainer and pump, is taken out fast to interchanger once to add flow and speed of cooling by pump.
Claims (2)
1. the oily whipped-up structure with former vacuum oven changes cooler construction into.
2. above fuel tank, open an oil outlet, below open an oil-in, it be with heated oil by oil outlet by in the pump suction interchanger.Blowing to the heating fin by blower fan takes away heat.Thereby reach the purpose of quick heat exchange.
