Abstract
The invention discloses an oil cooling system for a double-chamber vacuum oil quenching furnace. The oil cooling system comprises a furnace body and an oil tank, wherein a quenching oil cooling device is arranged on the oil tank; the quenching oil cooling device comprises a stirring motor, an impeller and a heat exchanger, wherein the heat exchanger is arranged on the transmission shaft of the stirring motor; and the impeller is arranged at the tail end of the transmission shaft of the stirring motor. The oil cooling system is characterized in that the stirring motor is arranged above the oil tank in an inclined way; annular flow guide plates are arranged on both two sides of the impeller in the oil tank; the two side surfaces of each annular flow guide plate are respectively welded with the two side surfaces of the oil tank; a thermocouple oil temperature detection device is arranged on the heat exchanger; and the signal feedback end of the thermocouple oil temperature detection device is connected with a water supply system of the heat exchanger and automatically controls the water supply system of the heat exchanger. The stirring motor is arranged above the oil tank in an inclined way, so that the problem of inconvenience in maintenance after the oil tank leaks is solved; and the control over the oil temperature is realized by controlling the flow rate of water supply by sending the feedback information to an automatic control valve in the water supply system of the heat exchanger by the thermocouple oil temperature detection device.
Description
Technical field
The present invention relates to a kind of double-chamber vacuum oil quenching furnace oil cooling system, especially a kind of adjustable oil cooling speed, double-chamber vacuum oil quenching furnace oil cooling system easy to maintenance.
Background technology
The heat agitated system of present vacuum oil quenching often designs the bottom at fuel tank; Be specially: the fuel tank bottom is provided with a transverse axis; Transverse axis one end places fuel tank, places an impeller is installed on the transverse axis of fuel tank, and the other end of transverse axis exceeds the side of fuel tank; Seal through sealing member and fuel tank side, and the agitator motor that rotates at its terminal installing drive transverse axis.But adopt this mode to have following problem:
1, can't regulate quenching oil refrigerative speed, thereby can't adjust in real time according to the difference of the process for cooling of workpiece;
2, because agitator motor is arranged on the fuel tank bottom, and the turning axle of agitator motor is arranged on the fuel tank side, in case the sealing-ring breakage causes leakage, must quenching oils all in the fuel tank drained and could keep in repair during maintenance, keeps in repair inconvenience;
3, workpiece places flow the not guiding of fuel tank at the process of cooling quenching oil, causes workpiece effect in process of cooling inhomogeneous.
Summary of the invention
Technical problem to be solved by this invention provides a kind of oil cooling system of double-chamber vacuum oil quenching furnace, has may command oil cooling speed, easy to maintenance, quenching oil water conservancy diversion good effectiveness.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of double-chamber vacuum oil quenching furnace oil cooling system comprises body of heater and fuel tank; Said fuel tank is arranged at the body of heater below; Contain quenching oil wherein, workpiece to be quenched places fuel tank, and said fuel tank is provided with the quenching oil refrigerating unit; Comprise agitator motor, impeller and interchanger; Said interchanger is arranged on the agitator motor transmission shaft, and it is terminal that said impeller is arranged at the agitator motor transmission shaft, and its innovative point is: said agitator motor is obliquely installed in the fuel tank top; The impeller both sides are provided with ring diversion plate in the said fuel tank, and weld with the fuel tank two sides respectively said ring diversion plate two sides; Said interchanger is provided with the warm proofing unit of thermopair oil, and automatically controlled valve links to each other in the warm proofing unit signal feedback end of said thermopair oil and the interchanger waterworks.
Further, said agitator motor links to each other with fuel tank through flange.
Further, said agitator motor transmission shaft is provided with the paddle wheel permanent sleeve, and said paddle wheel permanent sleeve outer rim props up flange inner wall.
The invention has the advantages that: through agitator motor being obliquely installed, thereby solved the problem that back maintenance inconvenience is revealed in former agitator motor turning axle and fuel tank contact position in fuel tank top; Detect the oil temperature of quenching oil in the fuel tank through the warm proofing unit of the oil of the thermopair on the interchanger; Thereby with feedback information send with the interchanger waterworks in automatically controlled valve; The flow of control service discharge is realized the control to the oil temperature; Thereby reach the purpose of control oil temperature, the required technological temperature of oily gentle workpiece is matched.The oil cooled flow guide system that this system also designs leads according to the required rational flow of quenching oil workpiece in quenching process, has guaranteed the cooling uniformity in the workpiece quenching process.The oil stirring system is installed on the pasta of quenching oil, need not to carry out vacuum-sealing, easy maintenance and installation in liquid state.
In addition, agitator motor is connected with fuel tank through flange, and is easy for removal and installation.Stability when the paddle wheel permanent sleeve can be used to guarantee the rotation of impeller.
