Please refer to Figure 1 to Figure 3 , including an arc component 100 and a cylindrical tube 200 disposed on the top of the arc component 100, and also including a reinforcing component 300 disposed in the arc component 100;

[0025] The reinforcement assembly 300 includes a rib ring 310, which is made of alloy steel and has a diameter larger than the auxiliary ring 340, a plurality of connecting arc rods 320 arranged in a circular array on the outer wall of the circumference of the rib ring 310, and the connecting arc rods 320 have a certain curvature, which is the same as the outer curvature of the shell 110, so that the connecting arc rods 320 are effectively built into the interlayer, and an impact plate 330 arranged at the end of the plurality of connecting arc rods 320, which is arranged at the center of the auxiliary ring 340, and the impact plate 330 has a certain curvature. The circumferential outer wall is welded with a connecting arc rod 320 and a curved wire 350. The bottom of the connecting arc rod 320 is welded with an annular auxiliary ring 340. The auxiliary ring 340 is made of alloy material and is at least two groups. The diameters of the two groups of auxiliary rings 340 are equidistant and gradually reduced. The tops of the tendon rings 310 and the auxiliary rings 340 are arranged in a circular array and welded with the curved wire 350. The curved wire 350 can be "S" shaped, which is convenient for combining multiple accessories with a curved structure to achieve a three-dimensional forming effect. One end of the curved wire 350 is welded to the circumferential outer wall of the impact-resistant plate 330.

[0026] In the process of combining the reinforcing component 300 and the shell 110, the shell 110 with the interlayer 180 can be first divided into two parts, such as the shell part 1 and the shell part 2. After the reinforcing component 300 is fixed at the bottom of the shell part 1, the shell part 2 is welded to the bottom of the reinforcing component 300, and the shell part 1 and the shell part 2 are combined, so that the reinforcing component 300 is more stably arranged in the interlayer 180.

Five connecting arc rods 32 are combined on the rib ring 310. 0, the end of the arc rod 320 is welded with an impact-resistant plate 330, so that the impact-resistant plate 330 is set at the center point to maximize the impact resistance. Between the impact-resistant plate 330 and the rib ring 310, gradually narrowing auxiliary rings 340 are arranged at equal intervals. The auxiliary rings 340 fill the gap between the impact-resistant plate 330 and the rib ring 310 and also play a reinforcing role. Finally, the curved wire 350 of the annular array is used to weld and combine multiple structures, so that the overall structure forms a three-dimensional composite explosion-proof effect, effectively achieving the purpose of explosion-proof.

The sealing ring 170 can be made of high-temperature resistant material with sealing effect in the existing technology, such as high-temperature resistant rubber.

[0029] Subsequently, in order to enable the furnace cover to be effectively combined with the furnace body and opened and closed, specifically, the circumferential outer wall of the arc component 100 is welded with wing plate 140 and wing plate 2 160, and circular holes 150 are reserved at the bottom of wing plate 140 and wing plate 2 160. The circular holes can be connected to shafts or pins, so that wing plate 140 and wing plate 2 160 can carry the furnace cover open while rotating.

[0030] Next, in order to increase the strength of the shell 110 and reserve enough space for internally placing the reinforcing component 300 , specifically, an interlayer 180 is reserved inside the shell 110 , and the thickness of the interlayer 180 matches the thickness of the reinforcing component 300 .

[0031] Furthermore, in order to ensure the normal use of the furnace cover, specifically, a pipe cap 210 is welded on the top of the cylindrical tube 200, and a pipe hole 220 is reserved in an integrally formed circumferential inner wall of the cylindrical tube 200.

[0032] At the same time, in order to increase the impact resistance and make the center point of the impact force have the strongest bearing capacity, specifically, the material of the impact-resistant plate 330 is a steel plate, and the thickness of the impact-resistant plate 330 is the same as the thickness of the interlayer 180 .
