Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic cell equipment, and specifically to an electrolytic cell flipping device. Background Technology

[0002] Alkaline water electrolysis is one of the methods for producing hydrogen through water electrolysis. Among existing hydrogen production technologies, alkaline water electrolysis is the most mature and widely used commercially. After passing electricity through alkaline ionized water, the hydrogen and oxygen ions in the water are decomposed. The electrolysis cell consists of a cell body, an anode, and a cathode. Most electrolysis cells use a diaphragm to separate the anode chamber and the cathode chamber. According to the different electrolytes, they are divided into three categories: aqueous solution electrolysis cells, molten salt electrolysis cells, and non-aqueous solution electrolysis cells. When direct current passes through the electrolysis cell, an oxidation reaction occurs at the anode-solution interface, and a reduction reaction occurs at the cathode-solution interface to produce the desired product.

[0003] In existing technologies, alkaline electrolyzers are mostly pressure filter structures, typically installed vertically. After assembly, the electrolyzers require transfer and transportation. However, during transport, due to their height, if the electrolyzers are transported vertically, their center of gravity is high, making them prone to tipping over and damaging themselves. Furthermore, tipping could injure workers. Therefore, it is necessary to flip the electrolyzers to transport them horizontally. However, the height and weight of the electrolyzers make this difficult. Existing technologies often use cranes and manual labor to flip the electrolyzers, requiring multiple lifting devices, resulting in low efficiency, large space requirements, and high investment costs for supporting facilities and lifting equipment. Summary of the Invention

[0004] To address the problem of difficulty in flipping electrolytic cells in existing technologies, this invention provides an electrolytic cell flipping device. This device facilitates the flipping of electrolytic cells, enabling the flipping of vertically positioned electrolytic cells to a horizontal position. Furthermore, it has a wide range of applications, suitable for electrolytic cells of different lengths and diameters.

[0005] To achieve the above objectives, the technical solution of this utility model is: an electrolytic cell tilting device, including an electrolytic cell, a support frame, and a drive mechanism for driving the support frame to tilt, the drive mechanism being connected to the support frame; the electrolytic cell is located inside the support frame, and a pulley assembly is arranged on the inner side of the upper end of the support frame, the pulley assembly being connected to the electrolytic cell. The drive mechanism can drive the support frame to tilt, thereby causing the support frame to drive the electrolytic cell to tilt. The function of the support frame is to limit and support the electrolytic cell, while providing an installation position for the pulley assembly and the variable support frame; the pulley assembly is used to connect with the electrolytic cell to ensure the safety and stability of hoisting and tilting the electrolytic cell.

[0006] The upper inner side of the support frame is equipped with an upper limit positioner connected to the electrolytic cell. A variable support frame is detachably connected to the lower end of the support frame. A hydraulic clamping mechanism is vertically mounted on the variable support frame to clamp the electrolytic cell. A lower limit positioner connected to the electrolytic cell is also located on the upper inner side of the variable support frame. The upper and lower limit positions ensure that the electrolytic cell does not tilt left or right during rotation and hoisting. The variable support frame provides installation positions for the lower limit positioner and the hydraulic clamping mechanism. The hydraulic clamping mechanism clamps the electrolytic cell and can adapt to electrolytic cells of different sizes and lengths according to its stroke.

[0007] Furthermore, the load-bearing frame includes two spaced-apart load-bearing beams, with a crossbeam fixedly positioned between the two beams. The load-bearing beams have an "L"-shaped structure. Hinges are provided at both the horizontal end and the lower vertical end of each load-bearing beam. The crossbeam connects to the two load-bearing beams to form the load-bearing frame, and the hinges are used to connect the load-bearing frame to the drive mechanism.

[0008] Furthermore, the drive mechanism includes a lifting beam and two drive components symmetrically arranged on the lifting beam. Each drive component includes a motor, a reducer, and a chain. The reducer is located on the outside of the lifting beam, with its input end connected to the output end of the motor. The output end of the reducer is connected to a drive shaft, on which a double sprocket is mounted. Both ends of the chain are hinged to two hinged seats on the load-bearing beam and mounted on the double sprocket. A guide limit seat is fixedly installed at the corner of the load-bearing beam. The motor drives the drive shaft to rotate via the reducer, which in turn drives the double sprocket to rotate. This causes the chain to pull the vertical part of the load-bearing beam, achieving the effect of the load-bearing frame driving the electrolytic cell to rotate. This allows the electrolytic cell to rotate 90°, changing its position from vertical to horizontal.

[0009] Furthermore, an upper pressure plate and a lower pressure plate are respectively provided at the upper and lower ends of the electrolytic cell. The top of the upper pressure plate is provided with lifting lugs corresponding to the pulley assembly. Shackles are movably provided on the lifting lugs and are connected to the pulley assembly through the shackles on the lifting lugs to ensure the safety and stability of lifting and turning the electrolytic cell.

[0010] Furthermore, the bottom of the horizontal section of each of the two load-bearing beams is provided with a pulley assembly. The pulley assembly includes a pulley seat, a pulley, and a steel wire rope. The pulley seat is connected to the horizontal section of the load-bearing beam. The pulley is rotatably mounted on the pulley seat. The steel wire rope is sleeved on the pulley and the shackle. The pulley is connected to the shackle through the steel wire rope, thereby achieving the purpose of connecting the pulley assembly to the electrolytic cell.

[0011] Furthermore, the upper end of the horizontal section of both load-bearing beams is provided with the upper limit positioner, which is an upper limit plate. The upper limit plate is detachably connected to the upper pressure plate. The connection between the upper limit plate and the upper pressure plate can limit the swaying of the electrolytic cell in the left and right directions, and can also prevent the electrolytic cell from being damaged by excessive descent of the previous step flipping device.

[0012] Furthermore, the variable load-bearing frame has an overall "L"-shaped structure. The hydraulic clamping mechanism includes a mounting plate and a hydraulic cylinder set on the top of the mounting plate. The mounting plate is set on the top of the horizontal part of the variable load-bearing frame. The telescopic end of the hydraulic cylinder is provided with a connecting plate connected to the lower pressure plate. The telescopic end of the hydraulic cylinder drives the connecting plate to move and makes the connecting plate fit against the lower pressure plate, so that the connecting plate is connected to the lower pressure plate, thereby achieving the purpose of clamping and supporting the electrolytic cell.

[0013] Furthermore, the lower limit component is provided on the inner side of the vertical part of the variable load-bearing frame. The lower limit component is a lower limit plate, which is detachably connected to the lower pressure plate. The position of the lower limit component can be changed according to the length of the electrolytic cell, so that the lower limit plate is connected to the lower pressure plate to prevent the electrolytic cell from swaying left and right during hoisting.

[0014] The beneficial effects of this utility model through the above technical solution are as follows:

[0015] This utility model has a reasonable structure and good performance. It can facilitate the flipping of electrolytic cells, turning them from a vertical to a horizontal position. Only one lifting device is needed to complete the flipping operation, saving factory space and investment costs, and improving the efficiency of flipping electrolytic cells. It also has a wide range of applications and can be used to flip electrolytic cells of different diameters and lengths.

[0016] This utility model's load-bearing frame serves to limit and support the electrolytic cell, and also provides an installation position for the pulley assembly and the variable load-bearing frame. The pulley assembly is connected to the electrolytic cell, and the pulleys of the pulley assembly are connected to the shackles on the lifting lugs on the upper pressure plate at the end of the electrolytic cell via steel wire ropes, which can ensure the safety and stability of lifting and turning the electrolytic cell. The variable load-bearing frame is detachably connected to the load-bearing frame, and different sizes of variable load-bearing frames can be replaced according to the diameter and length of the electrolytic cell, improving the applicability and ensuring that the hydraulic clamping mechanism works on the electrolytic cell.

[0017] The hydraulic clamping mechanism of this utility model uses the retracted end of the hydraulic cylinder to drive the connecting plate to move and make the connecting plate fit against the lower pressure plate. This connects the connecting plate and the lower pressure plate, achieving the effect of clamping and supporting the electrolytic cell, and improving the stability of the electrolytic cell when it is turned over. The extension length of the hydraulic cylinder can be adjusted according to the length of the electrolytic cell, so that the hydraulic clamping mechanism can clamp and support electrolytic cells of different lengths, thus improving its applicability.

[0018] The drive mechanism of this utility model uses a drive chain to achieve the effect of flipping the load-bearing frame. During the chain drive, one end of the chain pulls the vertical part of the load-bearing beam, so that the chain drives the load-bearing frame to flip. The flipping of the load-bearing frame can drive the electrolytic cell to flip as well, and can achieve a 90° flip of the electrolytic cell, so as to flip the electrolytic cell from a vertical state to a horizontal state.

The drive mechanism is connected to the support frame. The electrolytic cell 1 is located inside the support frame. A pulley assembly is provided on the inner side of the upper end of the support frame and is connected to the electrolytic cell 1. In this embodiment, the main function of the load-bearing frame is to limit and support the electrolytic cell 1. It also limits the installation of the chain 18 and provides an installation position for the variable load-bearing frame 19 and the pulley assembly. The drive mechanism can drive the load-bearing frame to rotate, so that the load-bearing frame drives the electrolytic cell 1 to rotate, thereby achieving the effect of rotating the electrolytic cell 1 from a vertical state to a horizontal state. The pulley assembly is connected to the electrolytic cell 1 to ensure the safety and stability of the hoisting and rotating process of the electrolytic cell.

In this embodiment, there are two upper limit stops on the inner side of the upper part of the support frame, and two lower limit stops on the inner side of the upper part of the variable support frame 19. The upper and lower limit stops are connected to the electrolytic cell 1 by bolts. The connection between the upper and lower limit stops and the electrolytic cell 1 ensures that the electrolytic cell 1 does not flip left or right during the flipping and hoisting process.

The two side plates are fixed to both sides of the load-bearing beam 6, the middle plate is fixed to the front of the load-bearing beam 6, and the pin is fixedly fitted onto the middle plate and the two side plates.

[0030] The drive mechanism includes a hoisting beam 15 and two drive components symmetrically arranged on the hoisting beam 15. The drive components include a motor 16, a reducer 17, and a chain 18. The reducer 17 is located outside the hoisting beam 15 and its input end is connected to the output end of the motor 16. The output end of the reducer 17 is connected to a drive shaft. A double sprocket is sleeved on the drive shaft. Both ends of the chain 18 are respectively hinged to two hinge seats 11 on the load-bearing beam 6 and sleeved on the double sprocket. A guide limit seat 12 is fixedly provided at the corner of the load-bearing beam 6. In this embodiment, the output end of the reducer 17 is connected to the transmission shaft via a coupling. The transmission shaft is rotatably connected to the lifting beam 15 via bearings. Each drive assembly includes two chains 18, both of which are mounted on a double gear. The two ends of the chains 18 are rotatably mounted on pins on two hinge seats 11. The ends of the chains 18 are located between the side plates and the middle plate of the hinge seats 11, and the middle plate separates the ends of the two chains 18. The guide limit seat 12 has an arc-shaped structure and a "U"-shaped cross-section. The guide limit seat 12 guides and limits the chains 18. The motor 16 is the power source and is equipped with an encoder. Its purpose is to ensure that the rotation angle of the electrolytic cell 1 is 90°, so as to ensure that the drive mechanism does not over-rotate the load-bearing frame and cause danger.

[0031] The electrolytic cell 1 is provided with an upper pressure plate 2 and a lower pressure plate 3 at its upper and lower ends, respectively. The top of the upper pressure plate 2 is provided with a lifting lug 4 corresponding to the pulley assembly, and a shackle 5 is movably provided on the lifting lug 4. In this embodiment, the upper pressure plate 2 has bolt holes for installing the lifting lug 4 and the upper limit positioner.

[0032] The bottom of the horizontal section of each of the two load-bearing beams 6 is provided with a pulley assembly. The pulley assembly includes a pulley seat 8, a pulley 9, and a wire rope 10. The pulley seat 8 is connected to the horizontal section of the load-bearing beam 6, the pulley 9 is rotatably mounted on the pulley seat 8, and the wire rope 10 is sleeved on the pulley 9 and the shackle 5. In this embodiment, the pulley 9 is rotatably connected to the pulley seat 8 through a pulley axle, and the pulley 9 of the pulley assembly is connected to the shackle 5 on the lifting lug 4 on the upper pressure plate 2 at the end of the electrolytic cell 1 through the wire rope 10, which can ensure the safety and stability of lifting and turning the electrolytic cell 1.

[0033] Both horizontal sections of the two load-bearing beams 6 are equipped with upper limit positioning components, which are upper limit plates 13. The upper limit plates 13 are detachably connected to the upper pressure plate 2. In this embodiment, the upper limit plates 13 have an "L"-shaped structure, and a reinforcing plate is also fixedly installed on the upper limit plates 13. The upper limit plates 13 are bolted to the load-bearing beams 6 and the upper pressure plate 2. This not only limits the swaying of the electrolytic cell 1 in the left and right directions, but also prevents the overturning device from excessively descending and colliding with and damaging the electrolytic cell 1.

[0034] The variable load-bearing frame 19 has an overall "L"-shaped structure. The hydraulic clamping mechanism includes a mounting plate 20 and a hydraulic cylinder 21 disposed on the top of the mounting plate 20. The mounting plate 20 is disposed on the top of the horizontal part of the variable load-bearing frame 19. The telescopic end of the hydraulic cylinder 21 is provided with a connecting plate 22 connected to the lower pressure plate 3. In this embodiment, the variable load-bearing frame 19 includes two variable load-bearing beams with an "L"-shaped structure and a transverse load-bearing beam installed between the two variable load-bearing beams. The upper end of the variable load-bearing beam is bolted to the lower end of the load-bearing beam 6 of the load-bearing frame. The purpose is to facilitate the disassembly and installation of the variable load-bearing frame 19. Different sizes of variable load-bearing frames 19 can be replaced according to the diameter and length of the electrolytic cell 1 to achieve the effect of adapting to different sizes of electrolytic cells 1. The extension length of the telescopic end of the hydraulic cylinder 21 can be adjusted according to the length of the electrolytic cell 1 so that the hydraulic cylinder 21 can clamp and support electrolytic cells 1 of different lengths, thereby improving the applicability. When the hydraulic cylinder 21 acts on the electrolytic cell 1, the extension end of the hydraulic cylinder 21 drives the connecting plate 22 to extend, so that the connecting plate 22 is completely attached to the lower pressure plate 3 of the electrolytic cell 1, and then the connecting plate 22 and the lower pressure plate 3 are fixed with bolts.

[0035] The lower limit member is provided on the inner side of the vertical part of the variable load-bearing frame 19.

The main function of the lower limit plate 14 is to prevent the electrolytic cell 1 from swaying left and right during hoisting. There are two lower limit plates 14. The lower limit plates 14 are bolted to the lower pressure plate 3. The position of the lower limit plates 14 on the variable load-bearing frame 19 can be changed according to the size of the electrolytic cell 1 to ensure that the lower limit plates 14 and the lower pressure plate 3 limit the electrolytic cell 1. The lower limit plates 14 can be directly connected to the variable load-bearing frame 19 by bolts. The variable load-bearing frame 19 has bolt holes spaced apart. Alternatively, the lower limit plates 14 can be connected to the variable load-bearing frame 19 by a slide rail. The lower limit plates 14 can move on the slide rail to adjust their position. After adjusting the position of the lower limit plates 14, they can be fixed with bolts to fix their position.

[0036] The working principle of this utility model is as follows: After the electrolytic cell 1 is assembled, the top of the upper pressure plate 2 is bolted to the lifting lug 4, and the shackle 5 is installed on the lifting lug; a lifting device of corresponding tonnage is connected to the lifting beam 15, such as a crane or gantry crane, and the tilting device is moved to the stacking position of the electrolytic cell 1 by the lifting device. According to the diameter of the electrolytic cell 1, the pulley assembly is installed in a suitable position, and the wire rope 10 of the pulley assembly is connected to the shackle 5; then the upper limit plate 13 is bolted to the upper pressure plate 2, and then a trial lift is carried out. The position of the lifting beam 15 is moved appropriately by the lifting device, or the position can be adjusted by the drive mechanism to ensure the vertical stability of the electrolytic cell 1 during the lifting process.

[0037] After the trial lifting is completed, the electrolytic cell 1 is lifted away from the stacking assembly station, the hydraulic clamping mechanism is fixed on the variable load-bearing frame 19, and the variable load-bearing frame 19 is bolted to the load-bearing frame using tools such as forklifts. Then, the hydraulic cylinder 21 is opened, and the extension end of the hydraulic cylinder 21 drives the connecting plate 22 to extend. After the connecting plate 22 is completely in contact with the lower pressure plate 3 of the electrolytic cell 1, the connecting plate 22 and the lower pressure plate 3 are fixed with bolts.

[0038] When motor 16 is turned on, the output end of motor 16 drives the transmission shaft to rotate through reducer 17. The transmission shaft drives the double gear to rotate, and the double gear drives the chain 18 to transmit power. One end of chain 18 pulls the vertical part of the load-bearing beam 6, realizing the 90° rotation of electrolytic cell 1. During the rotation of electrolytic cell 1, the height of electrolytic cell 1 can be slowly lowered by lifting equipment until the rotation is completed and the electrolytic cell 1 is placed in the designated position. Then, the hydraulic clamping mechanism and the variable load-bearing frame 19 are disassembled to carry out the hoisting and rotation of the next electrolytic cell 1 of the same model.
