[0002] Electric furnace smelting is a general term for smelting methods that use electricity as a heat source. Generally, ductile iron and gray iron are used for alternating smelting. Alternating smelting can greatly increase the service life of the furnace. Electric furnace smelting is divided into three smelting methods according to the heating method: arc melting, arc resistance compound melting, and induction melting. It is widely used in the refining process of rare metals and their alloys, tin, nickel and other metals.

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] Reference Figure 1-Figure 4 , an electric furnace smelting safety warning device comprises a long box 1, a long groove 2 is provided on the inner wall of the long box 1, a two-way screw 3 is rotatably connected to the inner wall of the long groove 2, a nut 4 is symmetrically threaded on the side wall of the two-way screw 3, each nut 4 is fixedly connected to the side wall with a support rod 5, and the other end of each support rod 5 is fixedly connected to a cooling plate 6, and a long hole 7 is provided on the top of each cooling plate 6, and an S-shaped tube 8 is fixedly installed on the inner wall of each long hole 7. The structural characteristics of the S-shaped tube 8 cause the coolant to cool down various parts of the side wall of the cooling plate 6, thereby better cooling the temperature detector 20. The bottoms of the two S-shaped tubes 8 are fixedly connected to a first hose 9, and a cooling box 14 is fixedly connected to the top of the long box 1, an electric push rod 16 is fixedly installed on the inner wall of the long box 1, and a temperature detector 20 is fixedly installed on the output end of the electric push rod 16. The temperature detector 20 can measure the temperature inside the electric furnace.
[0022] A semiconductor refrigerator is fixedly installed on the side wall of the cooling box 14, and a spiral tube 15 is fixedly installed on the inner wall of the cooling box 14. The heating end of the conductor refrigerator is located outside the cooling box 14, and the cooling end of the semiconductor refrigerator is located inside the cooling box 14, so that the inside of the cooling box 14 can be cooled. The structural characteristics of the spiral tube 15 cause the coolant to stay in the long box 1 for a longer time, so that the coolant can be fully cooled.
[0023] One end of the spiral tube 15 is fixedly connected to the second hose 11, and the other end of the second hose 11 is fixedly connected to the top of one of the S-shaped tubes 8. The second hose 11 is a retractable tube body.
[0024] A pump body 13 is fixedly installed on the top of the long box 1, and the output end of the pump body 13 is fixedly connected to the other end of the spiral tube 15. The input end of the pump body 13 is fixedly connected to a third hose 12, and the other end of the third hose 12 is fixedly connected to the top of another S-shaped tube 8. The third hose 12 is a retractable tube body.
[0025] Each cooling plate 6 has a side wall fixedly connected to a support rod 17, and two groups of first baffles 18 are symmetrically fixedly connected to the inner wall of the long box 1. A second baffle 19 is slidably connected inside every two adjacent first baffles 18. The side wall of each support rod 17 is fixedly connected to the side wall of the adjacent second baffle 19, and the top and bottom of each first baffle 18 are fixedly connected to the inner wall of the long box 1. Each second baffle 19 slides against the inner wall of the long box 1, so that the displacement of the second baffle 19 is restricted, and when the two second baffles 19 are against each other, under the action of the first baffle 18, the internal structure and air flow of the long box 1 can be blocked to a certain extent.
[0026] A motor 10 is fixedly mounted on the side wall of the long box 1 , and an output end of the motor 10 is fixedly connected to one end of the bidirectional lead screw 3 , so that the motor 10 can drive the bidirectional lead screw 3 to rotate.
[0027] In the utility model, the device is fixedly connected to the inner wall of the electric furnace. When the temperature of the inner wall of the electric furnace needs to be measured, the motor 10 is started, and the output end of the motor 10 drives the bidirectional screw 3 to rotate. Since the nut 4 and the inner wall of the long slot 2 slide against each other, the bidirectional screw 3 drives the nut 4 to move along the side wall of the bidirectional screw 3, and the nut 4 drives the support rod 5 to move, the support rod 5 drives the cooling plate 6 to move, the cooling plate 6 drives the support rod 17 to move, and the support rod 17 drives the second baffle 19 to move. The second baffle 19 moves in the gap generated by the two adjacent first baffles 18 under the restriction of the adjacent first baffles 18, and the gap between the two second baffles 19 increases, and then the electric push rod 16 is started, and the movable end of the electric push rod 16 drives the temperature detector 20 to extend out of the long box 1 and measure the temperature of the electric furnace. The temperature detector 20 is a prior art and is not described here.
[0028] When the temperature measurement is completed, the electric push rod 16 is started again to retract the temperature detector 20 into the long box 1, and then the motor 10 is started again. The motor 10 is a forward and reverse motor. The cooling plate 6 is driven to move through the motor 10 and other structures, and the side wall of the temperature detector 20 is clamped. Since the S-shaped tube 8 is filled with a sufficient amount of coolant, and the cooling plate 6 is a heat-conducting material, the cooling plate 6 transmits the low temperature in the coolant to the temperature detector 20, and cools the temperature detector 20. However, if the coolant frequently cools the temperature detector 20, the temperature of the coolant increases. In order to cool the coolant, the pump body 13 is started again. The pump body 13 is There is technology, which will not be described here. The output end of the pump body 13 absorbs the coolant through the first hose 9, the third hose 12 and other structures, and discharges the coolant into the spiral tube 15, and starts the semiconductor refrigerator in advance to reduce the temperature inside the cooling box 14, thereby cooling the coolant and discharging it into the S-shaped tube again through the second hose 11. When the cooling plate 6 moves, the second baffle 19 follows the movement through the support rod 17, and the gap between the two second baffles 19 is reduced until the two second baffles 19 are against each other, thereby forming a closed space inside the long box 1, thereby reducing the influence of the external high temperature on the cooling process inside the long box 1.
[0029] The cooling plate 6 drives the S-shaped tube 8 to move, and the S-shaped tube 8 drives the first hose 9 , the second hose 11 and the third hose 12 to move. Since the three hoses are all retractable tubes, they can be retracted and contracted following the movement of the S-shaped tube 8 .
[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
