Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Figure 1-3, a kind of efficient heat treatment furnace, comprise fire door 3, body of heater and be arranged on heat resisting brick 5 and the some bar shaped electrical heating elements 6 in body of heater, described fire door 3 is arranged on body of heater one side, described heat resisting brick 5 is laid on furnace body inside, described bar shaped electrical heating element 6 is horizontally installed on the inwall of body of heater, on the described body of heater inwall relative with fire door 3, be equipped with cooling tube 7, described body of heater top is provided with the rising pipe 8 being communicated with cooling tube 7, bottom of furnace body is provided with the water inlet pipe 9 being communicated with cooling tube 7, described water inlet pipe 9 and rising pipe 8 are all communicated with cooling tube 7 is in parallel, in described body of heater inside top surface, be fixed with two parallel vertical thermal baffles 11, the end face sealing of described thermal baffle 11 upper ends and body of heater inside, the two sides sealing of described thermal baffle 11 two side ends and body of heater inside, between described thermal baffle 11 lower ends and the bottom surface of body of heater inside, there is gap.
In order to increase cooling performance, realize water circulation use, described body of heater outside is provided with pond 10, and described water inlet pipe 9 is communicated with the water pump being arranged in pond 10, and described rising pipe 8 is communicated with pond 10.
In order to increase heat insulation effect, described body of heater comprises inner casing 4 and shell 1, between described inner casing 4 and shell 1, is provided with vacuum layer.
For the convenient turnover of controlling water coolant, in heating, make body of heater in closed state, increase heat insulation effect, described water inlet pipe 9 and rising pipe 8 are equipped with water valve with body of heater junction.
