Compared with the prior art, the utility model discloses a set up the separator in the sealed main part, the separator both can be right first sealing ring and second sealing ring carry on spacingly, prevent first sealing ring and second sealing ring take place to shift and make sealed inefficacy, again can with first sealing ring and second sealing ring separate, and then form twice and seal to improve sealed effect. In addition, the separator can be in first sealing ring with form a cavity between the second sealing ring, the cavity can fill protective gas when sealed, and then produces certain atmospheric pressure, because switching device, rotation heating reaction unit and rotation cooling device inside high temperature just have the malleation, first sealing ring with the second sealing ring is easy to be oxidized under high temperature state, leaks gas easily when one side receives the effect of malleation, consequently, makes through the atmospheric pressure of cavity the atmospheric pressure of first sealing ring with the atmospheric pressure of second sealing ring both sides is balanced, thereby can improve first sealing ring with the sealing performance of second sealing ring, thereby promote seal part's whole sealed effect.
Preferably, a third sealing ring is provided at an end of the sealing body adjacent to the first sealing ring. Therefore, the contact surfaces between the rotary heating reaction device and the adapter device and between the rotary cooling device and the adapter device can be sealed, and the sealing performance is further improved.
Preferably, a sealing and pressing device capable of adjusting the tightness of the seal is arranged at one end of the sealing main body close to the second sealing ring, and the sealing and pressing device is pressed against the second sealing ring. The sealing and compressing device can compress the first sealing ring and the second sealing ring to prevent the first sealing ring and the second sealing ring from being separated from the sealing main body, and the structural stability and reliability of the sealing part are ensured.
Specifically, the sealing and compressing device is of a circular structure, the edge of the sealing and compressing device extends out of a connecting lug, the sealing main body extends out of a connecting part, and the connecting lug is adjustably connected with the connecting part through a connecting piece.
Preferably, the number of the first sealing ring and/or the second sealing ring is two or more, and the first sealing ring and/or the second sealing ring are arranged in sequence along the central axis direction of the sealing main body.
Preferably, the isolation piece is of an annular structure, and the cross section of the isolation piece is of an I-shaped structure.
Preferably, the spacer is fixed to an inner wall of the sealing body by a connector.
A rotary furnace sealing device comprises a rotary device and a switching device sleeved with the rotary device, wherein a sealing part is arranged between the rotary device and the switching device. Because the feed end of rotary device can be rotary motion, and the discharge end of switching device is motionless, consequently, gap between both butt joints can be produced to the heat leakage, consequently, set up sealing member both can guarantee both their respective motion state, can make both's connection sealing effect better again.

Detailed Description
In order to explain technical contents, structural features, and effects achieved by the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.
Referring to fig. 1 to 3, the sealing device of the rotary furnace of the present invention includes a rotary device 2 and an adapter 4 sleeved with the rotary device 2, wherein a sealing member 5 is disposed between the rotary device 2 and the adapter 4.
As shown in fig. 3 and 4, the sealing member 5 includes a sealing main body 51, a spacer 52, a first sealing ring 53 and a second sealing ring 54, the sealing main body 51 has a cylindrical structure with two ends penetrating, the first sealing ring 53, the spacer 52 and the second sealing ring 54 are sequentially disposed in the sealing main body 51, and the spacer 52 is located between the first sealing ring 53 and the second sealing ring 54, so that a chamber 56 into which a protective gas can be filled is formed between the first sealing ring 53 and the second sealing ring 54. The spacer 52 has an annular configuration and an i-shaped cross-section. The spacer 52 is fixed to the inner wall of the sealing body 51 by a coupling member. By providing the spacer 52 in the seal main body 51, the spacer 52 can limit the first seal ring 53 and the second seal ring 54 to prevent the first seal ring 53 and the second seal ring 54 from being displaced to cause seal failure, and can separate the first seal ring 53 and the second seal ring 54 to form two seals, thereby improving the sealing effect. In addition, the isolation member 52 may form a chamber 56 between the first sealing ring 53 and the second sealing ring 54, and the chamber 56 is sealed and may be filled with a protection gas to generate a certain gas pressure to form a gas seal. Because the inside high and existence malleation of temperature of switching device 4 and slewer 2, first sealing ring 53 reaches second sealing ring 54 is easy to be oxidized under high temperature state, and easy gas leakage when one side receives the effect of malleation, consequently, atmospheric pressure through cavity 56 makes first sealing ring 53 reaches the atmospheric pressure balance of second sealing ring 54 both sides, thereby can improve first sealing ring 53 reaches the sealing performance of second sealing ring 54, thereby promotes the whole sealed effect of seal part 5.
As further shown in fig. 4, a third seal ring 55 is provided at an end of the seal body 51 adjacent to the first seal ring 53. Therefore, the contact surface between the rotating device 2 and the adapter device 4 can be sealed, and the sealing performance is further improved.
Referring to fig. 2 and 4, a sealing and pressing device 57 capable of adjusting the tightness of the sealing is disposed at an end of the sealing body 51 close to the second sealing ring 54, and the sealing and pressing device 57 presses against the second sealing ring 54. The seal pressing device 57 can press the first seal ring 53 and the second seal ring 54 to prevent them from being separated from the seal body 51, thereby ensuring structural stability and reliability of the seal member 5. Specifically, the sealing and compressing device 57 is a circular structure, and the edge of the sealing and compressing device extends out of the connecting ear 571, the sealing main body 51 extends out of the connecting portion 511, and the connecting ear 571 and the connecting portion 511 are adjustably connected through a connecting piece. The connecting piece is of a bolt and nut connecting structure, the position of the sealing and pressing device 57 relative to the sealing main body 51 is adjusted by adjusting the distance of the bolt screwed into the nut, the pressing force of the sealing and pressing device 57 against the second sealing ring 54 is adjusted, and the purpose of adjusting the sealing tightness is achieved.
Referring to fig. 2 and 4, the number of the first sealing rings 53 is two or more, and the first sealing rings 53 are sequentially arranged along the central axis direction of the sealing main body 51. The number of the second seal rings 54 is two or more, and in this case, the second seal rings 54 are arranged in order along the central axis direction of the seal body 51.
The utility model discloses because rotary motion can be done to slewer 2's feed end, and switching device 4's discharge end is motionless, consequently, can not take place to interfere for making both, and both butt joints department can leave the gap, and this gap can lead to leaking the heat, consequently, sets up above-mentioned both respective motion state both can both be guaranteed to seal part 5, can make above-mentioned both connection seal effect better again.
The above disclosure is only a preferred embodiment of the present invention, and certainly, the scope of the present invention should not be limited thereto, and therefore, the scope of the present invention is not limited to the above embodiments.
