Description

Technical Field

[0001] This invention relates to the field of blade recycling technology, specifically to a device and method for recycling carbon fiber from wind turbine blades. Background Technology

[0002] Wind turbine blades are the core components of wind turbines and contain a large amount of carbon fiber. Carbon fiber recycling can also be reused. Carbon fiber recycling generally uses a dissolution method to dissolve other substances and finally retain the carbon fiber.

[0003] For example, Chinese patent CN116116884B discloses a blade recycling system and method. The blade recycling system includes a blade fixing device, a blade traction device, a blade dissolving device, and a blade fiber recycling device. The blade fixing device and the blade fiber recycling device are respectively located at the inlet and outlet ends of the blade dissolving device. The blade dissolving device includes a dissolver for holding the dissolving liquid and an ultrasonic generator mounted on the dissolver. The dissolver has an injection port and a discharge port. The blade traction device can pull the head and root of the blade to move the blade into and out of the dissolver. The blade fiber recycling device can recover the blade fibers dissolved in the dissolver. This blade recycling system and method can recycle long fibers from blades, increasing the recycling value of the blades.

[0004] However, carbon fiber dissolution recycling requires temperature control of 40-70℃. The above structure is in an open state, which requires more energy consumption for heat preservation, which is not conducive to environmental protection. At the same time, there is less carbon fiber at the tip of the blade. In order to stabilize the traction of the blade, the carbon fiber is prone to breakage, which cannot guarantee stable traction and is not conducive to practical use.

[0005] Based on this, the present invention designs a wind turbine blade carbon fiber recycling device and method to solve the above problems. Summary of the Invention

[0021] A method for recycling carbon fiber from wind turbine blades includes the following steps:

[0022] Step 1: After the lumpy material in the fan blades of a set of reaction tanks has dissolved, the liquid in the reaction tanks is discharged through the drain pipe. The horizontal moving trolley drives the hoisting assembly to move. The liquid receiving end of the liquid receiving assembly is rotated to be misaligned with the hoisting assembly.

Then the loading component and the auxiliary unloading component separate, and the bottom of the empty loading component is sealed.

[0025] Step 4: The horizontal moving trolley moves the hoisting assembly, which in turn moves the empty loading assembly to the feeding assembly.

The receiving end of the liquid receiving assembly rotates to be misaligned with the hoisting assembly. The horizontal moving trolley then moves the hoisting assembly above the reaction tank. The hoisting assembly then moves the loading assembly into the reaction tank. After the hoisting assembly and the loading assembly separate, the top of the reaction tank is closed.

[0026] Step 5: The solution is added into the reaction vessel through the inlet pipe. The reaction vessel heats the solution to continue dissolving and decomposing it.

[0027] Step 6: Move the horizontally moving trolley to move the hoisting assembly above other reaction tanks and repeat the above steps.

[0028] Beneficial Effects: After the blocky material in the fan blades of the reaction tank is dissolved, the liquid in the reaction tank is discharged through the drain pipe. The horizontal moving trolley drives the hoisting assembly to move, and the liquid receiving end of the liquid receiving assembly rotates to be misaligned with the hoisting assembly. The hoisting assembly moves to the top of the reaction tank after dissolution, the top of the reaction tank opens, and the hanging end of the hoisting assembly hooks onto the loading assembly. The hoisting assembly drives the loading assembly to move upward to the top. The liquid receiving end of the liquid receiving assembly rotates to be directly below the bottom of the loading assembly below the hoisting assembly. The horizontal moving trolley drives the hoisting assembly to move, and the hoisting assembly drives the loading assembly to contact the auxiliary feeding assembly. The bottom of the loading assembly opens, and the fibers in the loading assembly fall into the auxiliary feeding assembly by their own gravity. Then the loading assembly and the auxiliary feeding assembly separate, and the empty loading assembly... The bottom of the component is sealed, and the horizontal moving trolley moves the hoisting assembly. The hoisting assembly moves the empty loading assembly to the feeding assembly. The feeding assembly conveys the lumpy material of the fan blades to be dissolved into the loading assembly. The receiving end of the liquid receiving assembly rotates to be misaligned with the hoisting assembly. The horizontal moving trolley moves the hoisting assembly above the reaction tank.

[0050] A set of horizontal moving trolleys 1: The drive end of the horizontal moving trolley 1 is fixedly connected to a hoisting component 2 for hanging the loading component 9 and a liquid receiving component 8 for receiving waste liquid. When the hoisting component 2 picks up and puts down the loading component 9, the liquid receiving component 8 is misaligned with the hoisting component 2. When the hoisting component 2 moves the loading component 9, the liquid receiving end of the liquid receiving component 8 is located directly below the hoisting component 2.

[0051] A set of feeding components 3: The feeding components 3 for feeding are located at one end of the horizontal moving trolley 1;

[0052] A set of auxiliary feeding components 7: A set of auxiliary feeding components 7 for assisting feeding is located at the other end of the horizontal moving trolley 1;

[0053] Multiple reaction tanks 6: Multiple reaction tanks 6 are arranged at equal intervals and located below the horizontal moving trolley 1. The liquid outlet end of the reaction tank 6 is connected to a drain pipe 4 and the liquid inlet end of the reaction tank 6 is connected to a liquid inlet pipe 5.

[0054] A loading assembly 9 for filling the fan blades with blocky materials is inserted inside the reaction vessel 6. The loading assembly 9 is connected to the hoisting assembly 2. When the loading assembly 9 comes into contact with the auxiliary feeding assembly 7, the bottom of the loading assembly 9 opens and the fibers inside the loading assembly 9 fall into the auxiliary feeding assembly 7 by their own gravity. When the loading assembly 9 and the auxiliary feeding assembly 7 come into contact, the liquid receiving assembly 8 is misaligned with the hoisting assembly 2.

[0055] The horizontal moving crane 1, the feeding assembly 3, the auxiliary unloading assembly 7, and the reaction tank 6 are all fixedly connected to the fixed frame of the plant;

[0056] After the lumpy material in the fan blades of a set of reaction tanks 6 has dissolved, the liquid in reaction tanks 6 is discharged through the drain pipe 4. The horizontal moving trolley 1 moves the hoisting assembly 2, and the liquid receiving end of the liquid receiving assembly 8 rotates to be misaligned with the hoisting assembly 2. The hoisting assembly 2 moves to the top of the reaction tank 6 after dissolution, and the top of the reaction tank 6 opens. The hanging end of the hoisting assembly 2 hooks onto the loading assembly 9, and the hoisting assembly 2 moves the loading assembly 9 upward to the top. The liquid receiving end of the liquid receiving assembly 8 rotates to be directly below the bottom of the loading assembly 9 below the hoisting assembly 2. The horizontal moving trolley 1 moves the hoisting assembly 2, and the hoisting assembly 2 moves the loading assembly 9 to contact the auxiliary feeding assembly 7. The bottom of the loading assembly 9 opens, and the fibers inside the loading assembly 9 fall into the auxiliary feeding assembly 7 by their own gravity. Then the loading assembly 9 and the auxiliary feeding assembly 7 separate, and the bottom of the empty loading assembly 9... The blockage is closed, and the horizontal moving trolley 1 moves the hoisting assembly 2. The hoisting assembly 2 moves the empty loading assembly 9 to the feeding assembly 3. The feeding assembly 3 transports the lumpy material of the fan blades that needs to be dissolved into the loading assembly 9. The receiving end of the liquid receiving assembly 8 rotates to be misaligned with the hoisting assembly 2. The horizontal moving trolley 1 moves the hoisting assembly 2 above the reaction tank 6. The hoisting assembly 2 moves the loading assembly 9 into the reaction tank 6. After the hoisting assembly 2 and the loading assembly 9 are separated, the top of the reaction tank 6 is closed. The dissolving liquid is added into the reaction tank 6 through the liquid inlet pipe 5. The reaction tank 6 heats the dissolving liquid to continue dissolving and decomposing. The horizontal moving trolley 1 moves the hoisting assembly 2 above other reaction tanks 6 and repeats the above actions to realize the automatic dissolution and recycling of carbon fiber of the fan blades, which is beneficial to practical use. At the same time, the reaction tank 6 is in a closed state during dissolution, which helps to reduce energy consumption.

[0057] Please see Figures 1-2 The hoisting assembly 2 includes an L-shaped hanging plate 21, an electronic weighing instrument 22, a gearbox 23, a rack 24, and a first motor 25.

The housing has a limiting groove, and the limiting groove is slidably connected to the rack 24. One end of the rotating shaft is fixedly connected to the drive end of the first motor 25.

[0059] The first motor 25 of the hoisting assembly 2 drives the gear ring in the gearbox 23 to rotate. The gear ring in the gearbox 23 drives the rack 24 to move downward. The rack 24 drives the electronic weighing instrument 22 to move downward. The electronic weighing instrument 22 drives the L-shaped hanging plate 21 to move. The L-shaped hanging plate 21 moves to the upper side of the loading assembly 9 in the reaction tank 6. The horizontal moving trolley 1 drives the L-shaped hanging plate 21 to move towards the loading assembly 9. The lower end of the L-shaped hanging plate 21 moves into the loading assembly 9. The first motor 25 drives the rack 24 to move upward. The rack 24 drives the L-shaped hanging plate 21 to move upward. The L-shaped hanging plate 21 drives the loading assembly 9 to move upward from the reaction tank 6, realizing the removal of the loading assembly 9 from the reaction tank 6.

[0060] After the fan blade blocks are filled into the loading assembly 9, the horizontal moving trolley 1 moves the L-shaped hanging plate 21. The L-shaped hanging plate 21 moves the loading assembly 9 to directly above the reaction tank 6. The L-shaped hanging plate 21 moves the loading assembly 9 into the reaction tank 6. After the loading assembly 9 moves into the reaction tank 6, the first motor 25 drives the rack 24 to continue moving downward. The rack 24 drives the L-shaped hanging plate 21 to continue moving downward. The horizontal moving trolley 1 moves the L-shaped hanging plate 21, and the L-shaped hanging plate 21 separates from the loading assembly 9. Then, the first motor 25 drives the rack 24 to move upward. The rack 24 drives the L-shaped hanging plate 21 to move upward, thus completing the installation of the loading assembly 9.

[0061] When the feeding component 3 fills the empty feeding component 9 with fan blade blocks, the electronic weighing instrument 22 weighs the fan blade blocks in the feeding component 9, so as to control the amount of fan blade blocks filled into the feeding component 9.

[0062] Please see Figures 1-2 , Figure 4 The liquid receiving assembly 8 includes an L-shaped support plate 81, a second motor 82, a second straight plate 83, a conical hopper 84, a fourth control valve 85, and a sixth pipe 86.

[0063] After the hoisting assembly 2 moves the loading assembly 9 to the top of the reaction tank 6, the second motor 82 of the liquid receiving assembly 8 drives the second straight plate 83 to rotate, and the second straight plate 83 drives the conical bucket 84 to rotate. The conical bucket 84 drives the loading assembly 9 directly below the hoisting assembly 2 to collect the dissolved liquid in the loading assembly 9, so as to prevent the liquid in the loading assembly 9 from dripping to other places and to avoid contaminating the processing environment. The fourth control valve 85 is in the closed state.

[0064] When the hoisting assembly 2 moves the loading assembly 9 downward or when the auxiliary unloading assembly 7 comes into contact with the loading assembly 9, the second motor 82 drives the second straight plate 83 to rotate. The second straight plate 83 drives the conical bucket 84 to rotate to the outside of the loading assembly 9, so as to avoid the conical bucket 84 affecting the downward movement of the loading assembly 9 or the unloading of the loading assembly 9. The fourth control valve 85 is in the closed state.

[0065] When the conical hopper 84 needs to be drained, the hoisting assembly 2 drives the conical hopper 84 to the drain position, opens the fourth control valve 85, and the waste liquid in the conical hopper 84 is discharged through the sixth pipe 86.

After the top of the loading assembly 9 moves to the end of the loading channel 32 near the horizontal moving trolley 1, the wind turbine blade block storage bin falls to the upper end of the conveyor belt 33 through the guide channel 31 of the loading assembly 3. The conveyor belt 33 drives the wind turbine blade block to move to the upward loading channel 32 and fall into the loading assembly 9 through the loading channel 32. The electronic weighing instrument 22 weighs the wind turbine blade block in the loading assembly 9 to facilitate the control of a quantitative amount of wind turbine blade block being filled into the loading assembly 9.
