It is characterized in that: being equipped with a ring v notch v in the furnace body upper end on burner hearth top, covering burner hearth top is equipped on annular notch
Cover board, surface is equipped with temperature sensor on the cover board, and cooling duct is equipped between cover board and furnace top cover, the cooling duct
Both ends are connected to the furnace body external space, and first with cooling duct corresponding matching is hinged on the furnace top cover of cooling duct one end
Cover board is hinged with the second cover board with cooling duct corresponding matching on the furnace body of the cooling duct other end, the first cover board with
The motor of a corresponding cooperation is respectively equipped on the outside of second cover board.
Based on the above technical solution, there can also be technical solution further below:
The cover board is corundum plate.
The lower surface of the cover board upper surface and cooling duct is in same level.
The electric heater unit is U-shaped Si-Mo rod, is equipped with wire connecting portion, and the U-shaped of Si-Mo rod at the both ends of Si-Mo rod
Portion is located in burner hearth, and the upper end of the wire connecting portion is upward through cover board, cooling duct and furnace top cover and extendes back out furnace top cover.
Utility model advantage:
The utility model structure is simple, it is easy to use, can directly be transformed on existing, pass through corundum plate and cooling
Channel avoids furnace top cover directly with the high temperature contact in burner hearth, effectively increases the service life of furnace top cover.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the A-A cross-sectional view in Fig. 1.
Specific embodiment:
As illustrated in fig. 1 and 2, a kind of protective device of high-temperature experiment electric stove furnace roof, it includes furnace body 1, is set in 1 side of furnace body
There is not shown console in figure, be covered with furnace top cover 2 on 1 top of furnace body, burner hearth is equipped in the furnace body 1 below furnace top cover 2
1a is equipped with one group of electric heater unit in burner hearth 1a, and cooling fan 6, the cooling are equipped on the position close to 1 bottom of furnace body
The cooling wind that fan 6 generates wraps up 1 outside of furnace body upwards, cools down to 1 outer wall of furnace body.
The electric heater unit is U-shaped Si-Mo rod 5, is equipped with wire connecting portion 5a, Si-Mo rod at the both ends on 5 top of Si-Mo rod
The U-shaped portion 5b of 5 lower parts is located at the lower part in burner hearth 1a, and the upper end of the wire connecting portion is upward through furnace top cover 2 and extendes back out furnace top cover 2
Outside connects to power supply cooperation.
It is equipped with a ring v notch v 1b in 1 upper end of furnace body on the top burner hearth 1a, covering burner hearth is equipped on annular notch 1b
The cover board 3 on the top 1a, it is described for corundum plate.On cover board 3 described one group with the relief hole of wire connecting portion 5a corresponding matching, so as to
The wire connecting portion 5a of U-shaped Si-Mo rod 5 passes through cover board 3 and stretches out upwards.
The vertical depth of the annular notch 1b is greater than cover board 3, thus in 3 upper surface of cover board and 2 lower surface of furnace top cover
Between be formed with a cooling duct 4, the both ends of the cooling duct 4 are connected to 1 outer space of furnace body, in cooling duct 4
The first cover board 4a is hinged on furnace top cover 2 above the opening of left end, first side cover board 4a is equipped with corresponding match
The motor 7 of conjunction, the end of the output shaft of motor 7 connect cooperation with the hinged seat on the outside of the first lower end cover board 4a.Pass through motor 7
The first cover board lower end is driven to open and close, to be communicated or sealed the left end of cooling duct 4 with 1 outer space of furnace body.
The second cover board 4b, the second cover board 4b mono- is hinged on furnace body 1 below at 4 right-end openings of cooling duct
Side is equipped with another motor 7 of corresponding cooperation, the hinge on the outside of the end of the output shaft of motor 7 and the second upper end cover board 4b
Joint chair connection cooperation.Drive the folding of the second cover board upper end by another motor 7, so as to make the right end of cooling duct 4 with
1 outer space of furnace body is communicated or sealed.Since the second cover board is upper end folding, so second cover board itself can be effective
The cooling wind for stopping cooling fan 6 to generate avoids it from entering from cooling duct right end.
3 upper surface of cover board the center point be equipped with temperature inductor sensor 3a, the temperature inductor sensor 3a,
Two motors 7 form electric signal with console not shown in figure by cable and connect cooperation.
Arrow in Fig. 1 is the flow direction for the cooling wind that cooling fan generates.
The course of work:
When temperature inductor sensor detects fusion temperature of the cover board upper surface temperature close to cover board, temperature inductor
Sensor issues signal to console, and the electric motor starting that then console control is located at furnace body two sides pulls the first lid of opening outward
Plate and the second cover board, so that the left and right ends of cooling duct are connected to furnace body outer space, so that the cooling that cooling fan generates
Wind is under the guidance of the first cover board, and from cooling duct left side, opening enters cooling duct, then from cooling duct right openings
Place is left, to cool down to cover board upper surface, cover board is avoided to melt.When the temperature of temperature inductor sensor cover board upper surface
When degree is lower than certain numerical value, temperature inductor sensor issues signal to console again, and the motor of furnace body two sides opens again
Trend furnace body side pushes the first cover board and the second cover board, the first cover board and the second cover board is closed, so that the left and right of cooling duct
Both ends and furnace body outer space completely cut off.
