Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell electrode plate transfer technology, and in particular to an electrolytic cell electrode plate transfer tooling. Background Technology

[0002] With the increasing global demand for clean energy, hydrogen energy, as a highly efficient and clean energy carrier, has received widespread attention. Water electrolysis for hydrogen production is a relatively convenient method and is gradually becoming the main market demand driver. This has spurred the continuous development of electrolyzer electrode technology to meet the growing demand for hydrogen production. Electrolyzers exhibit various resistances, such as electrolyte resistance, bubble resistance, diaphragm resistance, polarization resistance, and contact resistance. To meet gas production requirements, improvements in electrode structure design, such as adding concave-convex structures or uniformly distributed protrusions on the electrode surface, can reduce the distance between the electrode and the electrode mesh, decrease the resistance within the electrolyzer, increase current transmission density, and improve hydrogen production efficiency. Simultaneously, the electrode needs to withstand the pressure within the electrolyzer, the scouring effect of the electrolyte, and the stress generated by electrode reactions. Therefore, electrode plates are consumables and require frequent replacement. In large electrolyzers, the electrode weight is significant (e.g., electrode plates in alkaline electrolyzers can weigh tens of kilograms), and manual handling can easily lead to bumps and deformation, and can also affect the flatness and conductivity of the electrode plates.

[0003] Therefore, a tooling for transferring electrolytic cell plates is proposed to solve the problems mentioned above. Utility Model Content

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Reference Figures 1 to 6 This utility model provides a tooling for transferring electrolytic cell electrode plates, and the following embodiments are provided:

[0034] An electrolytic cell electrode plate transfer fixture includes a transfer carriage 100, an electrode plate clamp assembly 200, and a cleaning assembly 300. The transfer carriage 100 facilitates the transfer of electrode plates, the electrode plate clamp assembly 200 is used to fix the electrode plates, and the cleaning assembly 300 is used to clean the electrode plates. When transferring electrolytic cell electrode plates, the electrode plates can be fixed with the electrode plate clamp assembly 200, while the electrode plates are cleaned with the cleaning assembly 300. The transfer carriage 100 is then pushed to transfer the plates. This saves labor and also has the advantages of cleaning the electrode plates and recycling wastewater. It solves the problems in large electrolytic cells where the electrode plates are heavy, and manual handling can easily lead to bumps and deformation, and manual handling can also affect the flatness and conductivity of the electrode plates.

[0035] More specifically, the bottom of the transfer vehicle body 100 is fixedly connected to four casters 110 distributed at the four corners. A transfer handle 120 is fixedly connected to the rear side of the transfer vehicle body 100 for easy movement. An anti-slip pad made of rubber is fixedly connected to the outer side of the transfer handle 120 to improve grip comfort. The upper surface of the transfer vehicle body 100 is provided with a fixed platform 130, which includes a water collection surface and other surfaces. A protective plate surrounds the edge of the water collection surface, and a drain hole 131 is provided on the water collection surface. The washing water is collected through the water collection surface and discharged through the drain hole 131. The protective plate forms a ring, and the cross-section of the other surrounding surfaces is determined according to the water collection surface. In this embodiment, the surface is rectangular; therefore, the protective plate includes four baffles arranged in a rectangular column shape. Of the four baffles, the two baffles located on the front and right sides... There is a movable plate 140 and two fixed plates 150. The bottom of the fixed plate 150 is fixedly connected to the edge of the water collection platform. The bottom of the movable plate 140 is hinged to the edge of the water collection platform through the protective plate hinge 160. When the electrode plate is placed, the movable plate 140 can be folded down to make it easy to fix the electrode plate on the electrode plate clamp assembly 200. After the electrode plate is fixed, the movable plate 140 is folded up to form a complete enclosure with the fixed plate 150. The two sides of the enclosure can be fixedly connected to other baffles through magnetic or snap-fit ​​structures.

[0036] It should be noted that the water collection platform will promptly drain the water through the drain hole 131, so the bottom of the movable plate 140 does not need to be completely sealed. The baffles mainly prevent water from splashing everywhere. Of course, to achieve a better water-blocking effect, water-blocking edges can be set around the water collection platform, with four baffles located on the water-blocking edges. The height of the water-blocking edges is relatively low, so as not to affect the transfer of the electrode plate into the water collection platform, and at the same time reduce [the impact of water splashing]. In some other embodiments, all four baffles can be fixedly connected to the platform.

[0037] Other countertops are located next to the water collection countertop. Other countertops are equipped with water inlets 132. Water inlets 132 are located on the surface of the fixed platform 130. Water inlets 132 are equipped with water caps 170. The edge of the water cap 170 and the edge of the water inlet 132 can be connected by a hinge. A handle is fixedly connected to the top of the water cap 170. The water cap 170 can also be directly snapped into the water inlet 132.

[0038] The electrode plate clamp assembly 200 is mounted on the fixed platform 130 and is located inside the protective plate. The electrode plate clamp assembly 200 is used to clamp and fix the electrode plates. (Refer to...) Figure 2 , Figure 4 and Figure 5 The electrode clamp assembly 200 includes a clamping platform 210 and three grippers 220. The clamping platform 210 has a clamping center and three track grooves 230 extending radially along the circumference with the clamping center as the center. The grippers 220 are embedded in the corresponding track grooves 230 and can slide within the track grooves 230. A clamping spring 240 is provided between the outer ends of the grippers 220 and the track grooves 230.

[0039] The clamping spring 240 provides a spring force to push the jaws 220 toward the clamping center. When clamping the electrode plate, the jaws 220 should be pushed outward first, and then the electrode plate should be placed between the jaws 220. The jaws 220 should be released, and the outer edge of the electrode plate should be squeezed under the action of the spring force. The three jaws 220 should move inward to abut against the outer edge of the electrode plate to fix the electrode plate.

[0040] When the clamping spring 240 can also provide the elastic force to push the clamp 220 outward, the slot of the electrode plate is aligned with the clamp 220. As the electrode plate is placed, the clamp 220 is subjected to an inward force by the electrode plate, which is opposite to the elastic force provided by the clamping spring 240, and has the effect of fixing the electrode plate. That is, the three clamps 220 are pushed outward to fix the electrode plate.

[0041] To facilitate faster and easier fixing of the gripper 220, a central groove 250 is provided at the clamping center. The central groove 250 is interconnected with three track grooves 230. The central groove 250 is slidably equipped with a release pin 260 that can move up and down. Each track groove 230 is equipped with a release connecting rod 270. The two ends of the release connecting rod 270 are a pressing end and a control end, respectively. The pressing end is connected to the bottom end of the release pin 260, and the control end abuts against the bottom end of the gripper 220. A return spring 280 is provided at the bottom of the groove of the central groove 250 and the release pin 260. When the release pin 260 is pressed down, the release pin 260 drives the connecting rod to move down, thereby releasing the control end from abutting against the bottom end of the gripper 220, so that the clamping spring 240 pushes the gripper 220 to clamp the electrolytic cell plate.

[0042] At this point, the clamping spring 240 can provide two elastic forces, as shown in the reference. Figure 5 As shown, at this time, the clamping spring 240 provides the elastic force for the jaw 220 to move outward. The surface of the control end that abuts against the bottom end of the jaw 220 is a wedge-shaped surface. The control end prevents the jaw 220 from moving outward under the elastic force of the clamping spring 240. When the release pin 260 is pressed down, the jaw 220 moves outward under the elastic force of the clamping spring 240. The three jaws 220 are spread outward to fix the electrode plate.

[0043] More specifically, when the electrode plate is placed on top of the release pin 260, the weight of the electrode plate presses down on the release pin 260, compressing the return spring 280. This causes the release link 270 to move downwards, releasing the gripper 220. The clamping spring 240 pushes the gripper 220, thus clamping the electrode plate. To prevent damage to the electrode plate, a silicone pad is fixed to the outside of the gripper 220. This clamping method is simple. When the electrode plate is removed, the release pin 260, under the action of the return spring 280, causes the release link 270 to move upwards. Since the surface where the control end abuts against the bottom end of the gripper 220 is a wedge-shaped surface, when the release link 270 is released, the control end also causes the gripper 220 to move inwards, preparing for the next clamping of the electrode plate.

[0044] Similarly, the clamping spring 240 can also provide the elastic force for the gripper 220 to move inward, and the wedge surface can be adjusted accordingly.

[0045] The cleaning assembly 300 includes a spraying component 310, a liquid delivery component, a pressure unit, and a recovery component. The spraying component 310 includes a cleaning nozzle 311, which is located on the water collection platform and inside a protective plate. The liquid delivery component includes a water storage chamber 320 located within the transfer vehicle body 100. The transfer vehicle body 100 has a water inlet 132 communicating with the water storage chamber 320. The water inlet 132 can be located directly on the upper side wall of the water storage chamber 320, or water can be delivered from the water inlet 132 to the water storage chamber 320 through a pipe. A pressure unit is located on the connecting pipe between the cleaning nozzle 311 and the water storage chamber 320. The pressure unit is used to pump liquid into the cleaning nozzle 311. The pressure unit can be a submersible pump 330. A water pump switch 340 is fixedly connected to the rear side of the transport vehicle body 100. The submersible pump 330 is located on the inner bottom wall of the transport vehicle body 100. A water delivery hose is fixedly connected to the top of the submersible pump 330, passing through the inner top wall of the transport vehicle body 100 and fixedly connected to the cleaning nozzle 311. The water pump switch 340 is fixedly connected to the rear side of the transport vehicle body 100. The recovery component includes a drain plug 351 and a waste liquid collection chamber 350 located inside the transport vehicle body 100. Water from the drain hole 131 is discharged into the waste liquid collection chamber 350. The outer wall of the transport vehicle body 100 is provided with a drain outlet for discharging waste liquid from the waste liquid collection chamber 350. The drain plug 351 is located at the drain outlet. Use the handle of water cap 170 to open water cap 170 and then inject clean water into the water storage chamber 320 inside the transport vehicle body 100;

[0046] Then: Place the electrode plate on the clamp platform 210 and fix it with the jaws 220. After clamping, use the water pump switch 340 to let water enter the water supply hose so that the cleaning nozzle 311 sprays water to clean the electrode plate. When it is necessary to drain the sewage, open the drain plug 351 to drain the sewage.

[0047] Furthermore, to achieve better cleaning results, refer to Figure 6 The spraying component 310 also includes a support frame 312, a waterproof motor 313, and a rotating rod 314. The top of the support frame 312 is rotatably connected to the rotating rod 314, and the top of the rotating rod 314 is fixedly connected to the waterproof motor 313, which is fixedly connected to the top of the inner side of the support frame 312. The top of the rotating rod 314 is fixedly connected to the cleaning nozzle 311.

[0048] The waterproof motor 313 is started, which drives the rotating rod 314 to rotate. The rotating rod 314 drives the cleaning nozzle 311 to rotate, so that the cleaning nozzle 311 sprays water to clean the electrode plate.

[0049] Among them, the waterproof motor 313 is fixedly connected to the water pump switch 340 with a connecting wire, and the connecting wire is a waterproof wire.

[0050] Furthermore, the water collection platform is inclined, and the drain hole 131 is located at the lowest end of the water collection platform to facilitate rapid water collection. The top of the transfer vehicle body 100 is provided with a pentagonal array of drain holes 131, which are located on the side with the drain plug 351.

[0051] Specifically, in this embodiment, the inner bottom wall of the transfer vehicle body 100 has a sloping gradient, higher at the rear and lower at the front, with the water outlet located at a lower position to facilitate drainage. A partition is fixedly connected to the inner bottom wall of the transfer vehicle body 100, dividing the interior of the transfer vehicle body 100 into a waste liquid collection chamber 350 and a water storage chamber 320. Utilizing the side wall of the vehicle body to form the waste liquid collection chamber 350 and the water storage chamber 320 saves costs. Furthermore, a filtration system can be installed in the vehicle body, allowing water passing through the filtration system to flow back to the water storage chamber 320, reusing water resources and reducing water waste.
