Description

Technical Field

[0001] This invention relates to the field of solid waste resource utilization technology, and in particular to a transition isolation device and its working method for a decommissioned wind turbine blade treatment system. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] To process retired wind turbine blades, existing technologies primarily employ physical, chemical, and pyrolysis methods. Currently, pyrolysis is considered the most effective technique. Pyrolysis typically involves a pyrolysis furnace where the cut wind turbine blades are heated to pyrolyze the blade material. A separation conveyor system is usually installed between the pyrolysis furnace and other equipment. However, current separation conveyor systems have several problems: The introduction of protective gas was not taken into account, which allowed gas from the isolation conveying equipment or the previous process to enter the next process through the isolation conveying equipment. Furthermore, the processing atmosphere, including the surrounding gas environment and temperature environment, is different in some processing processes, which affects the processing effect of different processes on the fan blades, and thus affects the quality of the finally recovered fiber. The isolation conveyor is equipped with an inlet and an outlet at both ends, and gates are installed at the inlet and outlet respectively. The gates have a simple structure, which is raised and lowered by a motor. However, they are not properly sealed after closing. Furthermore, the movement of the gates cannot be guided during the raising and lowering process. After a certain period of operation, the overall sealing problem becomes more apparent. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a transition isolation device for a decommissioned wind turbine blade processing system, which effectively isolates the gas and temperature between two adjacent processes to ensure recycling quality.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: A transition isolation device for a decommissioned wind turbine blade handling system includes a housing with an inlet and an outlet on each side. A material drive mechanism is installed inside the housing to receive material from the inlet and discharge material from the outlet. An on / off assembly is installed inside or outside the housing, and the on / off assembly is sealed to the housing. The on / off assembly can rotate or move linearly relative to the housing to open or close the inlet or outlet. The on / off assembly can open one of the inlet and outlet at a time. The housing is provided with a gas inlet / outlet to introduce protective gas into the housing.

[0006] As described above, a transition isolation device for a decommissioned wind turbine blade handling system includes a rotor installed inside the housing, a rotary drive mechanism located at the top of the housing, the rotary drive mechanism passing through the housing and connected to the rotor to drive the rotor to rotate, and a cavity inside the rotor for accommodating materials, with the gas inlet / outlet communicating with the cavity.

[0007] As described above, a transition isolation device for a decommissioned wind turbine blade handling system includes an outlet seal, a first side seal, and a second side seal disposed around the rotor. The first side seal and the second side seal are connected to the outlet seal and are disposed on both sides of the outlet seal. During rotor rotation, the outlet seal, the first side seal, and the second side seal seal seal the inlet or the outlet. The size of the outlet seal is larger than the size of the outlet. The coverage area of ​​the first side seal, the second side seal, and the outlet seal along the rotor circumference is greater than the sum of the outlet area and half of the rotor circumference area.

[0008] As described above, a transition isolation device for a decommissioned wind turbine blade handling system includes a material driving mechanism comprising a driving power source and a transmission component. The transmission component is located inside the rotor, and the driving power source is located at the bottom of the housing. The driving power source passes through the bottom of the housing and the bottom of the rotor and is connected to the transmission component.

[0009] As described above, a transition isolation device for a decommissioned wind turbine blade handling system has support rings provided on the upper and lower parts of the rotor, respectively. The support rings contact the interior of the outer casing and the rotor, respectively, and serve as a seal.

[0010] As described above, a transition isolation device for a decommissioned wind turbine blade treatment system includes a kiln body as the outer shell, which is hollow inside. The inlet and outlet, which are connected to the hollow part inside the kiln body, are respectively provided at both ends of the kiln body. The switching components are fixed at both ends of the kiln body and can move linearly.

[0011] As described above, a transition isolation device for a decommissioned wind turbine blade handling system includes a gate valve as the on / off component. The gate valve includes a frame, with a front plate and a rear plate on both sides of the frame. The front plate and the rear plate are respectively provided with an inlet and an outlet through which materials can pass. A valve plate is provided inside the frame between the front plate and the rear plate. The valve plate has an opening that can communicate with the inlet and the outlet. The valve plate is connected to a valve plate drive mechanism. The valve plate drive mechanism is installed through the frame to drive the valve plate to control the on / off of the inlet or outlet. Valve plate seals are provided on the inner sides of both the front plate and the rear plate. The valve plate seals are in contact with the surface of the valve plate and maintain a set pressure.

[0012] As described above, a transition isolation device for a decommissioned wind turbine blade handling system includes a guide assembly inside the frame. The guide assembly includes a first limiting guide roller and a second limiting guide roller located on opposite sides of the frame. The first limiting guide roller and the second limiting guide roller each include a limiting block. A rotating roller is provided at the limiting block. The side of the valve plate can contact the rotating roller. A slide is also provided on the side of the limiting block, and the valve plate can move along the slide.

[0013] As described above, in a transition isolation device for a decommissioned wind turbine blade handling system, the material driving mechanism is either a roller type drive mechanism or a chain plate type drive mechanism.

[0014] Secondly, the present invention also provides a method for operating a transition isolation device for a decommissioned wind turbine blade handling system, comprising the following: When the inlet switch component in the outer shell is opened, the material driving mechanism works to allow the material to enter the outer shell. After the material has completely entered the interior of the outer shell, the inlet switch component closes the inlet. The material is driven forward by the material drive mechanism, or the material is moved to the outlet of the shell by the rotation of the on / off component; When the on / off component at the outlet in the housing is opened, the material drive mechanism operates, causing the material to move forward from the outlet.

[0015] The beneficial effects of the present invention are as follows: 1) In this invention, the outer shell is provided with a gas inlet / outlet to allow protective gas to be introduced into the shell, so that the gas inside the transition isolation device can be consistent with the gas in the next processing step. By setting the on / off component, only the inlet or outlet of the shell can be opened at a time. The on / off component is sealed to the shell to effectively improve the sealing performance. This can effectively isolate the gas and temperature environment of different processes, ensure the smooth progress of processes such as pyrolysis and low-temperature oxidation in the next process, improve the utilization value of recycled fibers, and has a reliable structure and convenient operation and maintenance. It is suitable for the large-scale recycling and processing of retired wind turbine blades.

[0016] 2) In this invention, a rotatable rotor is provided in the outer shell, and a cavity for accommodating materials is provided inside the rotor. The on / off assembly includes an outlet seal, a first side seal, and a second side seal. The size of the outlet seal is larger than the size of the outlet. The rotation of the rotor enables the material to be conveyed in a sealed state. By utilizing the matching seal between the rotor and the outer shell and the gas-assisted seal, effective isolation of various environments is achieved.

[0017] 3) In another embodiment of the present invention, the on / off component is selected as a gate valve. By alternately opening and closing the gate valves at both ends, it is ensured that one gate valve is always closed during material conveying. The on / off component is composed of a frame, a front plate and a rear plate. The valve plate is placed inside the frame to ensure the overall sealing performance when the on / off component is closed. The setting of the valve plate seal in the on / off component further ensures the sealing performance between the gate valve and the kiln body. The on / off component, together with the kiln body structure and gas introduction, achieves environmental isolation.

[0018] 4) The guide component structure is reasonably set in this invention. The guide component includes two oppositely arranged first limiting guide rollers and second limiting guide rollers. The first limiting guide roller and the second limiting guide roller each include a limiting block. A rotating roller is set at the limiting block. The setting of the rotating roller is conducive to the sliding of the valve plate along the slide and reduces the sliding resistance. Attached Figure Description

[0033] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0034] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. As described in the background section, existing transition isolation devices have poor structural sealing performance and cannot effectively isolate gases and temperatures. In order to solve the above technical problems, this invention proposes a transition isolation device for a decommissioned wind turbine blade treatment system.

[0035] Example 1 In a typical embodiment of the present invention, reference is made to Figure 1 As shown, a transition isolation device for a decommissioned wind turbine blade handling system includes a housing 21. An inlet and an outlet are respectively provided on both sides of the housing 21. A material driving mechanism is provided inside the housing 21 to receive material from the inlet and deliver material from the outlet. An on / off assembly is provided inside or outside the housing 21. The on / off assembly is sealed to the housing 21. The on / off assembly can rotate or move linearly relative to the housing 21 to open or close the inlet or outlet. One of the inlet and outlet is opened by the on / off assembly. The housing is provided with a gas inlet / outlet to introduce protective gas into the housing.

[0036] It should be explained that the material refers to the cut-off pieces of retired wind turbine blades, and the material pallet refers to the pallet formed by placing the material in a tray.

[0037] In this embodiment, reference Figure 1 and Figure 2 As shown, the outer shell 21 is supported by the support legs 23. The rotor 22 is installed inside the outer shell 21. The rotor 22 is rotatable relative to the outer shell 21. The rotary drive mechanism 24 is arranged on the top of the outer shell 21. The rotary drive mechanism 24 passes through the outer shell 21 and is connected to the rotor 22 to drive the rotor 22 to rotate.

[0038] refer to Figure 3 As shown, the outer shell 21 includes a lower base plate 215, an upper top plate 211, and a shell 212. The shell 212 is a cylindrical shell. The lower base plate 215 and the upper top plate 211 are arranged opposite to each other. The lower base plate 215 is supported by legs 23. The shell 212 is connected to the lower base plate 215 and the upper top plate 211 respectively. The two sides of the shell 212 protrude outward to form an inlet 213 and an outlet 214, which are arranged opposite to each other.

[0039] In this embodiment, the rotor 22 has a cylindrical structure and is installed inside the housing 21, fitting the inner surface of the housing 21. The rotor 22 has a cavity 221 to accommodate a material tray; a cover plate is provided on the top of the rotor 22 (an opening is provided in the cover plate to allow the protective gas to enter the cavity). The dimensions of the cavity 221 are adapted to the inlet 213 and outlet 214. The on / off assembly consists of an outlet seal 222, a first side seal 223, and a second side seal 224 arranged circumferentially on the rotor 22. The first side seal 223 and the second side seal 224 are respectively connected to the outlet seal 222, and the first side seal 223 and the second side seal 224 are located on both sides of the outlet seal 222. When the rotor cavity 221 is connected to the inlet 213, the outlet seal 222, the first side seal 223, and the second side seal 224 seal the outlet 214. The coverage area of ​​the first side seal 223, the second side seal 224, and the outlet seal 222 along the circumference of the rotor 22 is greater than the sum of the area of ​​the outlet and half of the circumference area of ​​the rotor 22. Thus, during the rotation of the rotor 22, the inlet and outlet are sealed simultaneously through the first side seal 223, the second side seal 224, and the outlet seal 222.

[0040] Furthermore, sealing strips are provided on the periphery of the opening of rotor 22, and the sealing strips can contact the outer casing 21 to ensure sealing during the rotation of rotor 22.

[0041] It should be noted that the outlet seal 222, the first side seal 223, and the second side seal 224 are connected as one unit, and the three are of the same height. The three can adopt a multi-rib structure or a solid structure. The outlet seal 222, the first side seal 223, and the second side seal 224 are in contact with the inner surface of the cylindrical shell 212 of the outer shell 21 to ensure sealing during the rotation of the material pallet and prevent leakage of protective gas.

[0042] The rotor 22 has an upper support ring 225 on its upper part and a lower support ring 226 on its lower part. Both the upper support ring 225 and the lower support ring 226 are rigid annular parts with the same or different inner diameters. The upper support ring 225 contacts the inner surface of the upper top plate 211 of the outer shell 21, and the lower support ring 226 contacts the inner surface of the lower bottom plate 215. Both the upper support ring 225 and the lower support ring 226 are in contact with the outer shell 21, so as to achieve support and sealing of the upper and lower surfaces of the rotor 22, so as to prevent the protective gas from leaking between the rotor 22 and the outer shell 21.

[0043] To ensure sealing during rotor 22 rotation, the angle A of the first side seal 223 and the second side seal 224 along the rotor circumference is greater than the angle B of the outlet seal 222 along the rotor circumference. The coverage angle of the first side seal 223, the second side seal 224, and the outlet seal 222 along the rotor circumference is greater than half of the rotor circumference area. In some examples, the first side seal 223, the second side seal 224, and the outlet seal 222 all have a set thickness, and the first side seal 223, the second side seal 224, and the outlet seal 222 are all connected to the cover plate on the top of the rotor.

[0044] In addition, the outrigger 23 supports the outer casing 21 and keeps the inlet 213 and outlet 214 at the same height as other processing equipment; the outrigger 23 can be an existing X-type outrigger, or the outrigger 23 can be an existing lifting structure to adjust the overall height.

[0045] The material drive mechanism 25 is used to receive and deliver material pallets. (See reference) Figure 4 and Figure 5 As shown, the material driving mechanism 25 includes a first drive motor 251, a transmission shaft 252, a transmission conversion mechanism 253, a first chain 254, and rotating rollers 255. The rotating rollers 255 are arranged in rows along the length of the cavity 221 inside the rotor 22, and the width of the rotating rollers 255 is smaller than the width of the cavity 221. Considering the layout of the structural space, the transmission shaft 252 of the first drive motor 251 passes through the lower base plate 215 and the bottom of the rotor 22 before entering the cavity and connecting with the transmission conversion mechanism 253. The transmission conversion mechanism 253 is a gear transmission mechanism and is connected to the drive sprocket 256. Driven sprockets are provided at both ends of each roller, and the ends of the rollers pass through the driven sprockets and are supported by the outer shell. The drive sprocket 256 is set below the plane of the roller. The drive sprocket 256 and the driven sprockets are connected by a first chain 254. There are two drive sprockets, and the two drive sprockets 256 are also connected by drive rollers. The drive rollers are also supported by the outer shell 21. Thus, there are two first chains. The rollers 255 are driven by the first chain 254 to rotate in both directions, driving the receiving and sending of the material pallet. The material driving mechanism provided is only one specific implementation example of the present invention. Other conventional mechanisms for receiving and sending material pallets also fall within the scope of the present invention.

[0046] In addition, the rotary drive mechanism 24 is located on the top of the upper plate 211 in the housing 21. The rotary drive mechanism adopts a rotary drive motor. The output end of the rotary drive motor passes through the upper plate and is connected to the rotor 22. The rotary drive motor drives the rotor 22 to rotate.

[0047] It is easy to understand that the upper top plate 211 of the outer casing 21 is provided with multiple gas inlets / outlets 26, through which protective gases, such as nitrogen and other suitable gases, can be connected to assist the sealing between the rotor 22 and the outer casing 21.

[0048] When receiving a material pallet, the opening of the cavity 221 of the rotor 22 aligns with the inlet 213 of the outer casing 21. The material pallet enters the cavity 221 of the rotor 22 under the action of the conveying mechanism and the material driving mechanism 25 of the previous process. When discharging a material pallet, the rotor 22 rotates 180° under the drive of the rotary drive mechanism 24, and the opening of the cavity 221 of the rotor 22 aligns with the outlet 214 of the outer casing 21. The material pallet enters the next process under the action of the material driving mechanism 25 and the conveying mechanism of the next process. Due to the sealed structure between the rotor 22 and the outer casing 21, the inlet 213 and the outlet 214 are not connected during rotation and during receiving and discharging of the material pallet, thus isolating the next processing unit from the external gas and temperature environment.

[0049] Example 2 The difference between this embodiment and Embodiment 1 is that: refer to Figure 6 As shown, the outer shell is a kiln body 63, the length of which can accommodate at least one material tray. The kiln body 63 has a set length and width, and a gas inlet / outlet 65 is provided at the top of the kiln body. Multi-ring ribs 64 are provided on the outside of the kiln body 63. The support legs of the kiln body 63 can be L-shaped fixed feet. The inside of the kiln body 63 is equipped with a material driving mechanism, i.e., a conveying mechanism. The conveying mechanism can adopt various conventional and well-known mechanisms suitable for material tray conveying, such as chain plates, rollers, etc. Chain plate conveying mechanisms are preferred.

[0050] refer to Figure 7 , Figure 8 and Figure 9 As shown, the conveying mechanism 66 consists of a second drive motor 661, chain plate 662, sprocket 663, second chain 664, chain support plate 665, and chain guard plate 666. The second drive motor 661 is fixed to the outside of the kiln body 63 and is connected to one of the sprockets 663. The second chain 664 is arranged to pass around the sprockets 663 at both ends. The second chain 664 is a large roller chain. The second chain 664 contacts the chain support plate 665, which is fixed to the side wall of the kiln body 63. The chain support plate 665 provides support to prevent the chain from sagging due to excessive length and load, improves the stress conditions of the second chain 664, and extends its service life and maintenance cycle. Lubricant can be added to the second chain 664 as needed. In addition, a bent chain guard plate 666 is provided on the inner wall of the kiln body 63, and the chain guard plate 666 is located on the upper side of the second chain 664.

[0051] When receiving a material pallet, the first gate valve 61 is open and the second gate valve 62 is closed. The material pallet enters the kiln body 63 under the action of the conveying mechanism from the previous process and the conveying mechanism 66. When sending out a material pallet, the first gate valve 61 is closed and the second gate valve 62 is open. The material pallet enters the next process under the action of the conveying mechanism 66 and the conveying mechanism of the next process. Because one gate valve is always closed, isolation of the gas and temperature environments between the kilns and between the tunnel kiln and the outside world is achieved.

[0052] It should be noted that the structure of the first gate valve 61 is the same as that of the second gate valve 62.

[0053] refer to Figure 10 and Figure 11 As shown, the first gate valve 61 includes a valve plate drive 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 seal 617.

[0054] The frame 614 is a rectangular frame, which is fixed to both ends of the kiln body. The frame 614 is a square frame composed of profiles or other processed parts, preferably with a "U" shaped cross section, so as to facilitate the detachable connection between the front plate 612, the rear plate 613 and the frame 614. The valve plate drive mechanism 611 is fixed to the top of the frame 614.

[0055] The front panel 612 and the rear panel 613 are mounted on the frame 614 and sealed to the frame 614, preferably using a detachable connection. The front panel 612 and the rear panel 613 are respectively provided with a first opening 6121 and a second opening 6131 through which the material pallet can pass, and the first opening 6121 and the second opening 6131 are arranged opposite to each other.

[0056] 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 to the valve plate drive mechanism 611, which drives it to move up and down. The valve plate 615 has an opening, namely the third opening 6151, through which the material tray can pass. When it moves up and down under the drive of the valve plate drive mechanism 611, it communicates with and closes 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 valve plate seal 617 ensures the sealing performance between the first gate and the kiln body.

[0057] Among them, the valve plate drive mechanism 611 adopts a conventional pneumatic, hydraulic or electric motor driven linear drive mechanism, and one or more valve plate drive mechanisms 611 can be used.

[0058] refer to Figure 10As shown, a guide assembly 616 is provided inside the frame 614. The guide assembly 616 plays a limiting and guiding role when the valve plate 615 moves up and down driven by the valve plate drive mechanism 611. The guide assembly 616 includes a first limiting guide roller 6161 located on one side inside the frame and a second limiting guide roller 6162 located on the other side inside the frame. The first limiting guide roller 6161 and the second limiting guide roller 6162 are arranged opposite to each other to ensure that the valve plate 615 does not deviate when moving up and down.

[0059] The first limiting guide roller 6161 and the second limiting guide roller 6162 each include multiple limiting blocks. The two adjacent limiting blocks on each side are spaced apart. The limiting blocks are fixed to the side of the frame. The limiting blocks are equipped with rotating rollers that can contact the side of the valve plate 615. The rotating rollers can rotate relative to the limiting blocks. A slide is provided on the side of the limiting blocks away from the frame. The two sides of the slide are claws that extend from the side of the limiting blocks. The space between the claws forms the slide, and the claws can contact the valve plate 615.

[0060] A valve plate seal 617 is provided around the first opening 6121 and the second opening 6131 of the front plate 612 and the rear plate 613. The valve plate seal 617 is fixedly installed on the front plate 612 and the rear plate 613. The valve plate seal 617 contacts both sides of the valve plate 615 and maintains a certain pressure. The valve plate seal 617 is made of sealing material. 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.

[0061] Example 3 This embodiment discloses the working method of a transition isolation device for a decommissioned wind turbine blade handling system as described in Embodiment 1 or Embodiment 2, including the following: When the on / off component at the inlet of the outer shell 21 is activated, such as the rotary drive mechanism 24, the first gate valve 61 is activated to open the inlet, and the material drive mechanism 25 works to allow the material to enter the outer shell 21. After the material has completely entered the interior of the outer shell 21, the on / off component at the inlet 213 closes the inlet. The material is driven forward by the material driving mechanism 25, or the material is moved to the outlet 214 of the outer shell 21 by the rotation of the switching component; When the on / off assembly at outlet 214 in housing 21 is opened, the material drive mechanism 25 operates, causing the material to move forward from outlet 214.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
