The connecting pieces 81 are positioned between two adjacent recessed holes 7. The inner side of the connecting ring 82 is fixed. There are at least two conical positioning pins 85, and the number of conical positioning pins 85 should be the same as the number of connecting pieces 81. The insertion of one end of the two conical positioning pins 85 into the two conical holes 84 can help the upper furnace body 1 and the lower furnace body 2 to be quickly aligned. The outer surface of the connecting ring 82 is provided with an annular concave groove 86. The inner side of the groove 86 is movable (i.e., can rotate and slide up and down) with an internal threaded mounting ring 87. At least two handles 88 are fixed on the outer surface of the internal threaded mounting ring 87. The number of handles 88 can be set by yourself. The internal threaded mounting ring 87 can be rotated by the handles 88.

[0019] The sealing assembly 6 is used to adjust the sealing performance of the joint gap between the upper furnace body 1 and the lower furnace body 2. The sealing assembly 6 includes a space adaptive component disposed inside the annular groove 3, an installation component disposed inside the inner groove 4, a sealing component disposed inside the annular groove 3, and an adjusting component. The sealing component includes a hollow sealing ring 61. A perforated support plate 62 is fixed inside the hollow sealing ring 61. The number of perforated support plates 62 can be set according to the diameter of the hollow sealing ring 61. The perforated support plates 62 can stably support the shape of the hollow sealing ring 61.

[0020] The mounting component includes two positive magnetic sheets 63 fixed to the inner surfaces of the two positioning holes 5 respectively, and an annular mounting plate 64 passing through the inner side of the inner groove 4. A hollow sealing ring 61 is fixed to the bottom of the annular mounting plate 64. The annular mounting plate 64 has a double cavity 65 (i.e., two cavities that are opposite each other and are in the same straight line). Two negative cones 66 slide on the inner side of the double cavity 65. One end of each negative cone 66 extends to the outer side of the annular mounting plate 64 and passes through the inner side of the two positive magnetic sheets 63 respectively. A conical alignment head 613 with a size that matches the conical alignment hole 9 is fixed on the top of the annular mounting plate 64.

[0021] The adjusting components include a connecting pipe 67 passing through the inner side of the annular mounting plate 64 and an air distribution box 68 fixed to the top of the upper furnace body 1. One end of the connecting pipe 67 extends into the hollow sealing ring 61 and is fitted into the recessed hole 7. The other end of the connecting pipe 67 is rotatably provided with an internal thread head 69. A conveying pipe 610 is provided at the bottom of the air distribution box 68. One end of the conveying pipe 610 is fixed with an external thread head 611. The connecting pipe 67 and the conveying pipe 610 are connected through the internal thread head 69 and the external thread head 611. An air pump 612 is fixed at the top of the air distribution box 68. The working principle and wiring method of the air pump 612 are common and are all conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selection according to their needs or convenience.

[0022] The space adaptive component includes two annular plates 614 that slide inside the annular groove 3, a hollow sealing ring 61 is disposed between the two annular plates 614, and springs 615 are fixed between the two annular plates 614 and the inner wall of the annular groove 3. The number of springs 615 can be set by the user.

[0023] In use: Align the upper furnace body 1 and the lower furnace body 2 vertically, so that one end of the conical alignment head 613 corresponds to the opening of the conical alignment hole 9. When closing between the upper furnace body 1 and the lower furnace body 2, the conical alignment head 613 and the conical alignment hole 9 can be quickly aligned and closed through sliding insertion. When aligned, the hollow sealing ring 61 will be inserted into the annular groove 3. Rotate the internal thread head 69 and the external thread head 611 of the upper and lower alignment to connect the connecting pipe 67 and the conveying pipe 610. Then, rotate the internal thread mounting ring 87 by the handle 88 until the internal thread mounting ring 87 is screwed onto the external thread annular ring 83 to complete the connection between the upper furnace body 1 and the lower furnace body 2.

[0024] When the sealing effect of the hollow sealing ring 61 weakens, especially in winter when the hollow sealing ring 61 shrinks slightly due to low temperature, a leak can be checked at the connection gap between the upper furnace body 1 and the lower furnace body 2. If a slight leak occurs due to weakened sealing effect, the air pump 612 can be started to send air through the delivery pipe 610 and the connecting pipe 67 to the hollow sealing ring 61, filling the hollow sealing ring 61 with a certain amount of gas so that it can fit tightly against the two annular plates 614, preventing gaps from appearing between them due to the shrinkage of the hollow sealing ring 61, which would reduce the sealing performance. When the hollow sealing ring 61 is inflated, the annular plates 614 will change according to the bulging or bulging of the hollow sealing ring 61 under the contraction performance of the spring 615.

[0025] When the electric furnace needs maintenance later, the upper furnace body 1 and the lower furnace body 2 can be separated by unscrewing the internal threaded mounting ring 87 and the external threaded annular ring 83 using the lever 88. If the hollow sealing ring 61 has a quality problem, the hollow sealing ring 61 and the annular mounting plate 64 can be pulled out of the inner groove 4. When pulling the annular mounting plate 64 and the hollow sealing ring 61, the negative electrode cone 66 will be forced to detach from the positive electrode magnetic plate 63 and slide into the double cavity 65. Then, a new hollow sealing ring 61 can be installed in the inner groove 4. Simply insert the conical alignment head 613 on the annular mounting plate 64 into the inner groove 4 and rotate the annular mounting plate 64 until the conical alignment head 613 slides into the corresponding positioning hole 5. This will cause the connecting pipe 67 to be locked in the corresponding recess 7. The negative electrode conical head 66 is first pushed into the double cavity 65 by the force at the opening of the inner groove 4. After the annular mounting plate 64 enters the inner groove 4, it is aligned with the positioning hole 5 and is locked into the positioning hole 5 by the attraction of the positive electrode magnetic sheet 63, thus fixing the annular mounting plate 64 and the hollow sealing ring 61.

[0026] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
