The one-way valve 103 is an existing device and is used for pressure relief. The rotating shaft 1 is used to stir the solution inside the furnace body. The rotating shaft 1 is driven by a separate motor, which will not be described in detail here; An outer sealing ring 3 is fixed between the two end plates 2. An outer static ring 6 and an inner static ring 7 for sealing are slidably sleeved on the inner sides of the two end plates 2. A dynamic ring 5 that matches the outer static ring 6 and the inner static ring 7 is fixedly sleeved on the outer side of the rotating shaft 1. Multiple transmission components are provided between the inner sides of the two end plates 2 and the corresponding outer static rings 6 and inner static rings 7, which are used to drive the outer static rings 6 and inner static rings 7 to slide alternately on the inner sides of the end plates 2, maintaining a seal with the ends of the dynamic rings 5. The initial position of the hammer of the inner static ring 7 is kept in contact with the dynamic ring 5, and the initial position of the outer static ring 6 is separated from the dynamic ring 5. In the embodiment of the present invention, an oil filling pipe 4 is fixed to the top surface of the outer sealing ring 3 for injecting lubricating oil; In the embodiment of the present invention, reference Figure 1-Figure 3 When the rotating shaft 1 is running, it can drive the outer fixed sleeve dynamic ring 5 to rotate, and the outer static ring 6 and the inner static ring 7 provided between the two ends of the dynamic ring 5 and the two end plates 2 maintain the sealing effect; When the rotating shaft 1 is running, the outer static ring 6 and the inner static ring 7 can be driven to slide alternately on the inner side of the end plate 2 through the cooperation of the transmission assembly, and keep in contact with the end of the dynamic ring 5 in turn to maintain the sealing effect. At the same time, during the alternating sliding of the outer static ring 6 and the inner static ring 7, the lubricating oil is injected into the inner side of the outer sealing ring 3 through the oil filling pipe 4. The lubricating oil can flow to the ends of the outer static ring 6 and the inner static ring 7 during the process of alternating sliding of the outer static ring 6 and the inner static ring 7 and fitting and separating with the end of the dynamic ring 5, further improving the lubrication effect while reducing the increased wear caused by the continuous fitting and sealing of the outer static ring 6 and the inner static ring 7 with the dynamic ring, and also improving the cooling effect and service life of the outer static ring 6 and the inner static ring 7; In the embodiment of the present invention, specifically, refer to Figure 3 、 Figure 8 、 Figure 9 The transmission assembly includes a drive ring frame 11, which is fixed to the end of the dynamic ring 5. The inner side of the end plate 2 is rotatably mounted with a transmission shaft 9 and a drive shaft 10. The outer side of the drive shaft 10 is fixedly sleeved with a drive gear 1001 that meshes with the drive ring frame 11. The inner side of the end plate 2 is rotatably mounted with a transmission column 901. A transmission chain 1002 for transmission is connected between the transmission column 901 and the end of the drive shaft 10. The outer sides of the transmission column 901 and the transmission shaft 9 are fixedly sleeved with transmission bevel gears 902 that mesh with each other. A transmission tooth plate 8 is slidably mounted on the inner side of the outer static ring 6, and a half-tooth transmission wheel 904 meshing with the transmission tooth plate 8 is fixedly sleeved on the end of the transmission shaft 9. A telescopic lever 12 that is adapted to the transmission tooth plate 8 is rotatably connected to the outer side of the end of the inner static ring 7, and is used to drive the inner static ring 7 to retract and separate from the dynamic ring 5. A driving tooth meshing with the driving gear 1001 is fixed on the outer side of the driving ring frame 11. The transmission chain 1002 adopts the existing sprocket chain transmission method, and the sprocket is fixedly sleeved on the transmission column 901 and the end of the driving shaft 10; In the embodiment of the present invention, return springs 801 are fixed between the two ends of the transmission tooth plate 8 and the inner part of the corresponding outer static ring 6. The telescopic lever 12 is rotatably mounted on the inner side of the end plate 2 and the end portion is rotatably connected to the inner static ring 7. A top column 1201 is fixedly mounted on the end portion of the telescopic lever 12 away from the inner static ring 7. A slot hole that matches the top column 1201 is provided at the end portion of the outer static ring 6. When the outer static ring 6 is in contact with the dynamic ring 5 to maintain a seal, the top column 1201 installed at the end portion of the telescopic lever 12 can be inserted into the inner part of the outer static ring 6 and fit into the end portion of the transmission tooth plate 8. As the transmission tooth plate 8 continues to push, the telescopic lever 12 can be rotated to push the inner static ring 7, so that the inner static ring 7 is separated from the dynamic ring 5. In the embodiment of the present invention, a fixing bracket 903 and a positioning bracket 1003 are fixed to the inner side of the end plate 2. The transmission shaft 9 is rotatably mounted inside the fixing bracket 903. The drive shaft 10 and the transmission column 901 are both rotatably mounted inside the positioning bracket 1003. The drive shaft 10 and the transmission column 901 always remain parallel. The installation position of the transmission column 901 is located outside the transmission shaft 9. In the embodiment of the present invention, two annular notches 203 are provided inside the end plate 2, and the outer static ring 6 and the inner static ring 7 are respectively slidably installed inside the corresponding annular notches 203. A plurality of supporting springs 701 are fixed between the outer static ring 6 and the inner static ring 7 and the corresponding annular notches 203. When the rotating shaft 1 runs, it can drive the outer fixed sleeve dynamic ring 5 and the driving ring frame 11 to rotate. As the driving gear 1001 and the driving ring frame 11 engage with each other, it can drive the driving gear 1001 in the positioning frame 1003. The transmission column 901 rotates and is driven to rotate by the transmission chain 1002 at the end, and then the two transmission bevel gears 902 are meshed with each other, which can drive the transmission shaft 9 to rotate inside the fixed frame 903. As the transmission shaft 9 rotates, the half-tooth transmission wheel 904 fixed on the outside can be driven to rotate. Through the rotation of the half-tooth transmission wheel 904, the outer static ring 6 can be driven to slide outward through the transmission tooth plate 8 until the end contacts the running dynamic ring 5 to maintain a seal. At this time, as the half-tooth transmission wheel 904 continues to push the transmission tooth plate 8 , which enables the transmission tooth plate 8 to squeeze the return spring 801 at the end and push the top column 1201. At this time, the telescopic lever 12 is pressed to push the inner static ring 7, so that the inner static ring 7 is retracted into the annular groove 203 opened inside the end plate 2 and separated from the running dynamic ring 5. As the other side of the half-tooth transmission wheel 904 rotates to the transmission tooth plate 8, the engagement with the transmission tooth plate 8 can be cancelled. At this time, the transmission tooth plate 8 is reset by the return spring 801, and the inner static ring 7 is reset by the cooperation of the support spring 701, and is re-engaged with the dynamic ring 5. To maintain the seal, the outer static ring 6 is reset by the cooperation of the support spring 701 and retracted into the annular notch 203 to complete an alternating cycle. During the alternating cycle, the outer static ring 6 and the inner static ring 7 can always maintain a seal with the dynamic ring 5, that is, when the outer static ring 6 moves and maintains a seal with the dynamic ring 5, the inner static ring 7 will separate from the dynamic ring 5. Similarly, when resetting, the inner static ring 7 is reset and fits with the dynamic ring 5 to maintain a seal, and then the outer static ring 6 is reset and retracted into the annular notch 203 to avoid affecting the sealing effect. In the embodiment of the present invention, when the outer stationary ring 6 and the inner stationary ring 7 are alternately in contact with the dynamic ring 5 to maintain a seal, as the lubricating oil is injected into the outer sealing ring 3 through the oil filling pipe 4, the lubricating oil can flow to the fitting position of the outer stationary ring 6 and the dynamic ring 5. When the outer stationary ring 6 retracts and the inner stationary ring 7 is pushed out, the lubricating oil can flow to the end of the outer stationary ring 6 and the contact surface between the inner stationary ring 7 and the dynamic ring 5. When the outer stationary ring 6 is pushed out and the inner stationary ring 7 retracts, the lubricating oil between the outer stationary ring 6 and the inner stationary ring 7 can flow to the end of the inner stationary ring 7, which further improves the lubrication effect and the cooling effect, ensures the sealing performance of the equipment and increases the service life of the equipment. In the embodiment of the present invention, reference Figure 6 、 Figure 7, the interior of the two end plates 2 are rotatably installed with limit rings 201, and the two limit rings 201 are fixedly sleeved on the outside of the rotating shaft 1; by arranging the limit rings 201 inside the end plates 2, when the rotating shaft 1 is running, the limit rings 201 can be driven to rotate inside the end plates 2 to ensure the running stability of the rotating shaft 1 In the embodiment of the present invention, reference Figure 7 、 Figure 8 , an arc-shaped oil baffle 202 is fixed to the inner side of each of the two end plates 2, and the installation position of the arc-shaped oil baffle 202 is located on the inner side of the corresponding inner static ring 7; through the arrangement of the arc-shaped oil baffle 202, when the lubricating oil drips through the inner static ring 7, it can drip on the surface of the arc-shaped oil baffle 202, and then flow along the arc-shaped oil baffle 202 to the lowest point and then drip again on the inner side of the inner static ring 7, and then with the rotation of the inner static ring 7, the lubricating oil is driven to rise and circulate, while also avoiding the phenomenon of splashing caused by lack of diversion of the lubricating oil; Example 2: Based on Example 1, on the basis of Example 1, refer to Figure 9 An oil storage tank 301 is provided on the inner side of the outer sealing ring 3, and an oil outlet pipe 302 is fixed inside the oil storage tank 301. The oil storage tank 301 is located directly below the oil filling pipe 4. The end of the oil filling pipe 4 is connected to two sections of oil distribution pipes 401. The ends of the two sections of oil distribution pipes 401 extend to the ends of the outer static ring 6 respectively. In the embodiment of the present invention, a filter cover 303 is fixed between the two end plates 2, and the installation position of the filter cover 303 is located directly below the two sections of the oil distribution pipe 401; In the embodiment of the present invention, the oil reservoir 301 is provided so that the lubricating oil flowing down the outer stationary ring 6 can drip into the oil reservoir 301 and then be discharged through the oil outlet pipe 302 for recovery. The end of the oil filling pipe 4 is connected to two sections of oil distribution pipes 401, which can ensure that the lubricating oil introduced into the outer sealing ring 3 drips accurately onto the contact surface between the outer stationary ring 6 and the dynamic ring 5, thereby ensuring the lubrication effect. In the embodiment of the present invention, further, by setting the filter cover 303, the lubricating oil introduced into the outer sealing ring 3 can be filtered to prevent impurities from entering the contact surface between the outer static ring 6 and the dynamic ring 5, thereby affecting the sealing effect and service life.
