Abstract
The utility model discloses an oil cooling system of a double-chamber vacuum oil quenching furnace, which comprises a furnace body and an oil tank, wherein the oil tank is provided with a quenching oil cooling device. The oil cooling system also comprises a stirring motor, an impeller and a heat exchanger, wherein the heat exchanger is arranged on a 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; two ring-shaped guide plates are respectively arranged at the two sides of the impeller in the oil tank; the two sides of each ring-shaped guide plate are respectively welded with the two sides of the oil tank; the heat exchanger is provided with a thermocouple oil temperature detection device; and a signal feedback end of the thermocouple oil temperature detection device is connected with an automatic control valve in a water supply system of the heat exchanger. The stirring motor is arranged above the oil tank in an inclined way, so that the problem that the oil tank is inconvenient to maintain after leakage can be solved; and the feedback information is sent into the automatic control valve in the water supply system of the heat exchanger by the thermocouple oil temperature detection device, so that the oil temperature control can be realized by controlling the flow rate of water supply quantity.
Description
Technical field
The utility model relates to a kind of double-chamber vacuum oil quenching furnace oil cooling system, especially a kind of capable of regulating oil speed of cooling, 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 arranges a transverse axis, transverse axis one end places fuel tank, place an impeller is installed on the transverse axis of fuel tank, the other end of transverse axis exceeds the side of fuel tank, seal by sealing member and fuel tank side, and drive the agitator motor that transverse axis rotates its terminal installation.But there are the following problems to adopt this mode:
1, can't regulate the oil cooled speed of quenching, 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, quenching oils all in the fuel tank must be drained and could keep in repair during maintenance, keeps in repair inconvenience;
3, workpiece places fuel tank in the not guiding that flows of process of cooling quenching oil, causes workpiece effect in process of cooling inhomogeneous.
The utility model content
Technical problem to be solved in the utility model provides a kind of oil cooling system of double-chamber vacuum oil quenching furnace, has controlled liquefaction speed of cooling, easy to maintenance, characteristics that the quenching oil water conservancy diversion is effective.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of double-chamber vacuum oil quenching furnace oil cooling system, comprise body of heater and fuel tank, described fuel tank is arranged at the body of heater below, contain quenching oil wherein, treat that quenching workpiece places fuel tank, be provided with quenching oil cooling device on the described fuel tank, comprise agitator motor, impeller and interchanger, described interchanger is arranged on the agitator motor transmission shaft, it is terminal that described impeller is arranged at the agitator motor transmission shaft, and its innovative point is: described agitator motor is obliquely installed in the fuel tank top; The impeller both sides are provided with ring diversion plate in the described fuel tank, and weld with the fuel tank two sides respectively described ring diversion plate two sides; Be provided with thermopair oil temperature proofing unit on the described interchanger, described thermopair oil temperature proofing unit signal feedback end links to each other with automatically controlled valve in the interchanger waterworks.
Further, described agitator motor links to each other with fuel tank by flange.
Further, be provided with the paddle wheel permanent sleeve on the described agitator motor transmission shaft, described paddle wheel permanent sleeve outer rim props up flange inner wall.
The utility model has the advantage of: by agitator motor being obliquely installed in fuel tank top, thus the problem of maintenance inconvenience after having solved former agitator motor turning axle and revealing with the oil tank joint synapsis; Detect the oil temperature of quenching oil in the fuel tank by the thermopair oil temperature proofing unit on the interchanger, thus with feedback information send with the interchanger waterworks in automatically controlled valve, the control service discharge
Flow realize control to oil temperature, thereby reach the purpose of control oil temperature, the required technological temperature of oil temperature and 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 by flange, and is easy for removal and installation.Stability when the paddle wheel permanent sleeve can be used to guarantee the rotation of impeller.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the oil cooling system of a kind of double-chamber vacuum oil quenching furnace of the utility model.
Embodiment
The oil cooling system of a kind of double-chamber vacuum oil quenching furnace shown in Figure 1 comprises body of heater 1 and fuel tank 2, and fuel tank 2 is arranged at body of heater 1 below, and wherein the contain quenching oil treats that quenching workpiece 3 places fuel tank 2.Be provided with quenching oil cooling device on the fuel tank 2, comprise agitator motor 4, impeller 5 and interchanger 6, interchanger 6 is arranged on the agitator motor transmission shaft, and it is terminal that impeller 5 is arranged at the agitator motor transmission shaft.Make things convenient for the water conservancy diversion situation of situation and quenching oil for improving work-piece cools effect, use and maintenance, agitator motor is obliquely installed in the fuel tank top; The impeller both sides are provided with ring diversion plate 7 in the fuel tank 2, and weld with fuel tank 2 two sides respectively ring diversion plate 7 two sides; Be provided with thermopair oil temperature proofing unit on the interchanger 6, its signal feedback end links to each other with automatically controlled valve in the interchanger waterworks.
The mode that agitator motor links to each other with fuel tank by flange is installed in the top of fuel tank, and guarantees the rotational stabilization of impeller by paddle wheel permanent sleeve 8, and its outer rim props up flange inner wall.
Big area to workpiece when being conducive to the quenching oil ejection is surrounded cooling.
During specific works, quenching oil in the fuel tank 2 is by 5 rotations of agitator motor 4 impeller, so that quenching oil blows to workpiece 3 equably along ring diversion plate 7 directions, the quenching oil that is heated by workpiece is the quick top by ring diversion plate again, through constantly reciprocal again after the quick cooling of interchanger 6, reach the purpose of workpiece Quick uniform cooling.
