[0046] As introduced in the background, the prior art transition isolation device structure has poor sealing performance and cannot effectively isolate the gas and temperature, in order to solve the above technical problems, the present application proposes a transition isolation device for a decommissioned fan blade processing system.

[0047] Embodiment one

[0048] In a typical embodiment of the present application, referring to Figure 1 A transition isolation device for a decommissioned fan blade processing system, including a housing 21, the two sides of the housing 21 are respectively provided with an inlet and an outlet, a material driving mechanism is arranged in the housing 21 to receive material from the inlet and send out material from the outlet, a on-off assembly is arranged inside or outside the housing 21, the on-off assembly is in sealing connection with the housing 21, the on-off assembly can rotate relative to the housing 21 or move linearly to open or close the inlet or outlet, one of the inlet and outlet is opened through the on-off assembly, the housing is provided with a gas inlet / outlet to introduce protective gas into the inside of the housing.

[0049] It should be explained that the material refers to the decommissioned fan blade block after cutting, and the material tray refers to the material tray formed by placing the material in the tray.

[0050] In this embodiment, referring to Figure 1 and Figure 2 The housing 21 is supported by the leg 23, a rotor 22 is arranged in the housing 21, the rotor 22 is rotatable relative to the housing 21, a rotary drive mechanism 24 is arranged at the top of the housing 21, the rotary drive mechanism 24 is connected with the rotor 22 through the housing 21 to drive the rotor 22 to rotate.

[0051] Referring to Figure 3 The housing 21 includes a lower bottom plate 215, an upper top plate 211 and a shell 212, the shell 212 is a cylindrical shell, the lower bottom plate 215 is arranged opposite to the upper top plate 211, the lower bottom plate 215 is supported by the leg 23, the shell 212 is connected with the lower bottom plate 215 and the upper top plate 211 respectively, the two sides of the shell 212 respectively protrude outward to form an inlet 213 and an outlet 214, the inlet 213 and the outlet 214 are arranged opposite to each other.

[0052] In this embodiment, the rotor 22 is a cylindrical structure, which is installed in the inner space of the housing 21 and is adapted to the inner surface of the housing 21. The rotor 22 has a cavity 221 for accommodating the material tray inside, i.e. a cover plate is arranged at the top of the rotor 22 (considering that the protective gas enters the inside of the rotor, the cover plate is provided with an opening so that the protective gas can enter the cavity through the opening), and the size of the cavity 221 is adapted to the inlet 213 and the outlet 214. The on-off assembly is an outlet sealing member 222 arranged in the circumferential direction of the rotor 22, a first side sealing member 223 and a second side sealing member 224, which are connected to the outlet sealing member 222 respectively, and the first side sealing member 223 and the second side sealing member 224 are arranged on both sides of the outlet sealing member 222. When the cavity 221 of the rotor is communicated with the inlet 213, the outlet sealing member 222 and the first side sealing member 223 and the second side sealing member 224 seal the outlet 214, and the covering area of the first side sealing member 223, the second side sealing member 224 and the outlet sealing member 222 along the circumferential direction of the rotor 22 is greater than the sum of the area of the outlet and half of the area of the rotor 22 in the circumferential direction, so that the inlet and the outlet are simultaneously sealed by the first side sealing member 223, the second side sealing member 224 and the outlet sealing member 222 during the rotation of the rotor 22.

[0053] Moreover, sealing strips are arranged on the circumferential side of the opening of the rotor 22, which can be in contact with the housing 21 to ensure the sealing during the rotation of the rotor 22.

[0054] It should be noted that the outlet sealing member 222, the first side sealing member 223 and the second side sealing member 224 are connected as a whole, and the heights of the three are the same, and the three can adopt a multi-rib structure or a solid structure, and the outlet sealing member 222 and the first side sealing member 223 and the second side sealing member 224 are in contact with the inner surface of the cylindrical shell 212 of the housing 21 to ensure the sealing during the rotation of the material tray and avoid the leakage of the protective gas.

[0055] The upper support ring 225 is arranged at the upper part of the rotor 22, and the lower support ring 226 is arranged at the lower part of the rotor 22. The upper support ring 225 and the lower support ring 226 are both rigid annular members, and the inner diameters thereof are the same or different. The upper support ring 225 is in contact with the inner surface of the upper top plate 211 of the housing 21, and the lower support ring 226 is in contact with the inner surface of the lower bottom plate 215. The upper support ring 225 and the lower support ring 226 are both in contact with the housing 21 to achieve the support and sealing of the upper and lower parts of the rotor 22, so as to avoid the leakage of the protective gas from between the rotor 22 and the housing 21.

[0056] To ensure the sealing of the rotor 22 during rotation, the first side seal 223 and the second side seal 224 have a larger angle A along the rotor circumferential direction than the outlet seal 222 has an angle B along the rotor circumferential direction, and the covering angle of the first side seal 223, the second side seal 224 and the outlet seal 222 along the rotor circumferential direction is greater than half of the rotor circumferential area; in some examples, the first side seal 223, the second side seal 224 and the outlet seal 222 each have a set thickness, and the first side seal 223, the second side seal 224 and the outlet seal 222 are each connected with the cover plate of the top of the rotor.

[0057] In addition, the leg 23 supports the shell 21 and keeps the inlet 213 and the outlet 214 in line with the height of other processing equipment; the leg 23 can adopt an existing X-shaped leg, and the leg 23 can also adopt an existing lifting structure to adjust the overall height.

[0058] The material driving mechanism 25 is used to receive and send out the material tray. Referring to Figure 4 and Figure 5 As shown, the material driving mechanism 25 includes a first driving motor 251, a transmission shaft 252, a transmission conversion mechanism 253, a first chain 254 and a rotating roller 255. The rotating roller 255 is arranged in the cavity 221 of the rotor 22 along the length direction of the cavity 221, and the width of the rotating roller 255 is smaller than the width of the cavity 221. Considering the arrangement of the structural space, the transmission shaft 252 of the first driving motor 251 passes through the lower bottom plate 215 and the bottom of the rotor 22 and enters the cavity, and is connected with the transmission conversion mechanism 253. The transmission conversion mechanism 253 is a gear transmission mechanism, is connected with a driving sprocket 256, and both ends of each rotating roller is provided with a driven sprocket. The end of the rotating roller passes through the driven sprocket and is supported by the shell. The driving sprocket 256 is arranged below the plane where the rotating roller is located, the driving sprocket 256 and the driven sprocket are connected by the first chain 254, and the driving sprocket has two parts. The two driving sprockets 256 are also connected by a driving roller, and the driving roller is also supported by the shell 21. In this way, the first chain has two parts. The rotating roller 255 is driven by the first chain 254 to rotate in both directions, thereby receiving and sending out the material tray. The material driving mechanism provided at present is only one of the specific implementation examples of the present application, and other conventional mechanisms for receiving and sending out the material tray also belong to the scope of the present application.

[0059] In addition, the rotary driving mechanism 24 is arranged at the top of the upper top plate 211 in the shell 21, and adopts a rotary driving motor. The output end of the rotary driving motor passes through the upper top plate and is connected with the rotor 22, so that the rotor 22 is driven to rotate by the rotary driving motor.

[0060] It is easy to understand that the upper top plate 211 of the shell 21 is provided with a plurality of gas inlet / outlet ports 26, through which a protective gas such as nitrogen or other suitable gas can be introduced to assist the sealing between the rotor 22 and the shell 21.

[0061] When receiving a material tray, the cavity 221 of the rotor 22 is aligned with the inlet 213 of the shell 21, and the material tray is introduced into the cavity 221 of the rotor 22 under the action of the conveying mechanism of the previous process and the material driving mechanism 25. When sending out the material tray, the rotor 22 is rotated by 180° under the drive of the rotary driving mechanism 24, and the cavity 221 of the rotor 22 is aligned with the outlet 214 of the shell 21, and the material tray is introduced into the next process under the action of the material driving mechanism 25 and the conveying mechanism of the next process. Due to the sealing structure between the rotor 22 and the shell 21, the inlet 213 and the outlet 214 are not connected during rotation and during receiving and sending out the material tray, thereby achieving the isolation of the next processing device from the gas environment and temperature environment of the outside world.

[0062] Embodiment Two

[0063] The difference between this embodiment and Embodiment One is:

[0064] As shown in Figure 6 , the shell is a kiln body 63, the length of the kiln body 63 can accommodate at least one material tray, the kiln body 63 has a set length and width, the top of the kiln body 63 is provided with a gas inlet / outlet port 65, the outside of the kiln body 63 is provided with a plurality of ring ribs 64, the legs of the kiln body 63 can be fixed with L-shaped fixing feet, and the inside of the kiln body 63 is provided with a material driving mechanism, i.e. a conveying mechanism, which can adopt conventional and well-known mechanisms suitable for conveying material trays, such as chain plates, rollers, etc. Preferably, a chain plate conveying mechanism is adopted.

[0065] As shown in Figure 7 , Figure 8 and Figure 9 , the conveying mechanism 66 is composed of a second driving motor 661, a chain plate 662, a sprocket 663, a second chain 664, a chain support plate 665, a chain protection plate 666, etc. The second driving motor 661 is fixed to the outside of the kiln body 63, the second driving motor 661 is connected with one of the sprockets 663, the second chain 664 is arranged around the two ends of the sprockets 663, wherein the second chain 664 adopts a large roller chain, the second chain 664 is in contact with the chain support plate 665, the chain support plate 665 is fixed to the side wall of the kiln body 63, and the chain support plate 665 provides a supporting force to prevent the second chain 664 from falling due to excessive length and weight, thereby improving the stress condition of the second chain 664, prolonging its service life and maintenance period, and the second chain 664 can be lubricated as needed; in addition, the chain protection plate 666 is arranged in a bent manner on the inner wall of the kiln body 63, and the chain protection plate 666 is arranged on the upper side of the second chain 664.

[0066] When receiving the material tray, the first gate valve 61 is opened, and the second gate valve 62 is in a closed state. The material tray enters the kiln body 63 under the action of the conveying mechanism of the previous process and the conveying mechanism 66. When sending out the material tray, the first gate valve 61 is in a closed state, and the second gate valve 62 is opened. The material tray enters the next process under the action of the conveying mechanism 66 and the conveying mechanism of the next process. Since one gate valve is always in a closed state, the gas environment and temperature environment between the kiln bodies and the tunnel kiln and the outside are isolated.

[0067] It should be noted that the structure of the first gate valve 61 is the same as that of the second gate valve 62.

[0068] Reference Figure 10 and Figure 11 As shown in the drawings, the first gate valve 61 comprises a valve plate driving mechanism 611, a front plate 612, a rear plate 613, a frame 614, a valve plate 615, a guide assembly 616, and a valve plate sealing element 617.

[0069] The frame 614 is a rectangular frame fixed to both ends of the kiln body. The frame 614 is a square frame composed of a profile or other processed shaped parts. Preferably, a "U" shaped cross section is adopted to facilitate the detachable connection of the front plate 612, the rear plate 613, and the frame 614. The valve plate driving mechanism 611 is fixed to the top of the frame 614.

[0070] The front plate 612 and the rear plate 613 are installed on the frame 614 and realize sealing with the frame 614. Preferably, detachable connection is adopted. The front plate 612 and the rear plate 613 are respectively provided with a first opening 6121 and a second opening 6131 through which the material tray can pass. The first opening 6121 and the second opening 6131 are oppositely arranged.

[0071] The valve plate 615 is installed in the space formed by the front plate 612, the rear plate 613, and the frame 614, and is connected with the valve plate driving mechanism 611 and driven by the valve plate driving mechanism 611 to move up and down. The valve plate 615 is provided with an opening, i.e., a third opening 6151, through which the material tray can pass. When driven by the valve plate driving mechanism 611 to move up and down, the third opening 6151 is in communication with and closed by the first opening 6121 and the second opening 6131 on the front plate 612 and the rear plate 613. The front plate 612 and the rear plate 613 protect the valve plate 615, effectively ensuring the service life of the valve plate 615. Moreover, the sealing performance between the first gate and the kiln body is ensured by the valve plate sealing element 617.

[0072] Among them, the valve plate driving mechanism 611 adopts a conventional linear driving mechanism driven by gas pressure, liquid pressure, or motor. One or more valve plate driving mechanisms 611 can be adopted.

[0073] Reference Figure 10As shown, the frame 614 is internally provided with a guide assembly 616, which plays a limiting and guiding role when the valve plate 615 is driven to move up and down by the valve plate driving mechanism 611. The guide assembly 616 includes a first limiting guide roller 6161 located on one side of the frame inside and a second limiting guide roller 6162 located on the other side of the frame inside, and the first limiting guide roller 6161 and the second limiting guide roller 6162 are oppositely arranged to ensure that the valve plate 615 does not deviate when moving up and down.

[0074] The first limiting guide roller 6161 and the second limiting guide roller 6162 each include a plurality of limiting blocks, and adjacent two limiting blocks on each side are arranged at an interval distance. The limiting blocks are fixed to the side of the frame, and the limiting blocks are provided with rotating rollers which can contact the side of the valve plate 615. The rotating rollers are rotatable relative to the limiting blocks. The side of the limiting blocks away from the frame is provided with a slide, and the two sides of the slide are provided with clamping claws extending from the side of the limiting blocks. The space between the clamping claws forms a slide, and the clamping claws can contact the valve plate 615.

[0075] The front plate 612 and the rear plate 613 are provided with a valve plate sealing element 617 around the first opening 6121 and the second opening 6131. The valve plate sealing element 617 is fixedly installed on the front plate 612 and the rear plate 613, and the valve plate sealing element 617 contacts both sides of the valve plate 615 and maintains a certain pressure. The valve plate sealing element 617 is made of sealing material, and the sealing material is preferably made of high-temperature-resistant, corrosion-resistant and wear-resistant material to ensure a certain sealing performance when the valve plate 615 closes the first opening and the second opening.
