Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell equipment technology, and more specifically to a movable, pull-out electrolytic cell electrode plate fixing device. Background Technology

[0002] An electrolytic cell is the core equipment for realizing the electrolysis process. It uses a direct current electric field to drive the directional migration of ions in the electrolyte, causing redox reactions at the anode and cathode to convert electrical energy into chemical energy. A bipolar electrolytic cell adopts a stacked structure, integrating components such as the cathode, anode, bipolar plates, gaskets, and diaphragm. Among these, the bipolar plates are a key material in the electrolytic cell, serving both conductive and electrolyte-separating functions.

[0003] Currently, most electrolytic cell production workshops use a simple stacking method to store electrolytic cell plates. This method has two significant drawbacks: first, the compressive stress generated by stacking is concentrated on the bottom plate, which can easily lead to plastic deformation, affecting the flatness of the plate and the assembly accuracy of the electrolytic cell later; second, the lack of effective isolation between the plates makes them prone to friction during handling and storage, causing the plating on the plates to peel off. In addition, although existing patented technologies (such as patent CN222455244 U) propose plate fixing devices, the storage and fixing space of these devices is limited, increasing the production cost of enterprises. Moreover, the fixed location of the devices makes it inconvenient to transport electrolytic cell plates on the production line.

[0004] Therefore, there is an urgent need to develop a new type of electrolytic cell electrode fixing device that can effectively alleviate the compressive stress of the electrode plate, reduce surface damage, improve the utilization rate of storage space, and meet the flexible transportation needs of the production line. Utility Model Content

[0005] To address the shortcomings of existing electrolytic cell electrode plate storage methods and fixing devices, this utility model provides a mobile, pull-out electrolytic cell electrode plate fixing device. This device not only facilitates flexible movement on the production line but also adapts to electrode plates of different specifications and sizes. Furthermore, its innovative pull-out design effectively expands the electrode plate storage space without increasing the floor space required.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a movable pull-out electrolytic cell electrode plate fixing device, the electrode plate fixing device includes a fixed base plate, a movable pulley is provided below the fixed base plate, a guide rail is provided on the fixed base plate, and two sets of parallel and opposite electrode plate placement racks are perpendicular to the fixed base plate; the electrode plate placement rack includes a set of fixed comb grooves and a set of movable comb grooves, the fixed comb grooves and the movable comb grooves are connected by a screw adjustment mechanism; the fixed comb grooves are fixed to the fixed base plate, and the movable comb grooves are movablely connected to the fixed base plate through the guide rail under the action of the screw adjustment mechanism.

[0007] Furthermore, the fixed comb tooth groove and the movable comb tooth groove are respectively provided with comb tooth-shaped slots for placing the electrode plates. The comb tooth-shaped slots are evenly spaced and the direction of the comb teeth is perpendicular to the plane of the fixed base plate.

[0008] Furthermore, the screw adjustment mechanism includes a threaded rod and a threaded sleeve. The threaded rod is fixedly inserted into the movable comb tooth groove, and an adjustment handwheel is provided at the end of the threaded rod. The threaded sleeve is fixed to the fixed comb tooth groove.

[0009] Furthermore, both the fixed comb tooth groove and the movable comb tooth groove are provided with pull-out comb tooth grooves on both sides, and the pull-out comb tooth grooves can be stretched or contracted.

[0010] Furthermore, both the fixed comb tooth groove and the movable comb tooth groove are provided with a pull-out groove for the pull-out comb tooth groove to extend and retract; the upper and lower ends of the pull-out groove are provided with slide rails, and the pull-out comb tooth groove is pulled out through the ball slide rails.

[0011] Furthermore, each of the described retractable comb teeth is provided with a handle at its outer end.

[0012] Furthermore, both ends of the fixed comb tooth groove and the movable comb tooth groove are provided with a first pin hole, and the inner end of the pull-out comb tooth groove is provided with a second pin hole. The first pin hole and the second pin hole are fixed by a pin.

[0013] Furthermore, the movable pulley includes a combination of a set of directional wheels and a set of omnidirectional wheels.

[0014] The beneficial effects of this utility model are as follows: Compared with the prior art, the movable and retractable electrolytic cell electrode plate fixing device provided by this utility model can achieve efficient storage and flexible adaptation of electrode plates through its ingenious structural design. Multiple electrode plates are fixed by correspondingly setting comb-shaped slots on two sets of parallel plates, and the electrode plates can be precisely inserted along both sides and confined within the slots. The distance between the movable and fixed comb-shaped slots can be flexibly controlled by adjusting the handwheel to meet the storage requirements of electrode plates of different sizes. At the same time, the built-in hidden retractable comb-shaped slots can flexibly expand the storage space according to actual needs, increasing the number of electrode plates that can be stored and improving the utilization rate of enterprise production space.

Detailed Implementation

[0020] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model. Example

[0021] like Figures 1-4 As shown, a movable, pull-out electrolytic cell electrode plate fixing device includes a fixed base plate 1 with movable casters below it. The fixed base plate 1 has a guide rail 15 and two sets of parallel, opposite, and perpendicular electrode plate placement racks. Each electrode plate placement rack includes a set of fixed comb grooves 9 and a set of movable comb grooves 5, connected by a screw adjustment mechanism. The fixed comb grooves 9 are fixed to the fixed base plate 1, and the movable comb grooves 5 are movably connected to the fixed base plate 1 via the guide rail 15 under the action of the screw adjustment mechanism. The distance between the fixed comb grooves 9 and the movable comb grooves 5 can be adjusted by the screw adjustment mechanism to accommodate electrode plates of different sizes.

[0022] The fixed comb groove 9 and the movable comb groove 5 are respectively provided with comb-shaped slots 8 for placing the electrode plates. The comb-shaped slots 8 are evenly spaced, and the direction of the comb teeth is perpendicular to the plane of the fixed base plate 1. In use, the two ends of the electrode plate can be respectively aligned with the slots of the movable comb groove 5 and the fixed comb groove 9 to fix the electrode plate. It should be noted that the structure of the electrode plate is not limited to square electrode plates. The comb-shaped slot structure design of this device is also suitable for circular electrolytic cell electrode plates, and the width and depth of the comb grooves can be designed according to the size of commonly used electrode plates in the workshop.

[0023] In one embodiment, the screw adjustment mechanism includes a threaded rod 3 and a threaded sleeve 7. The threaded rod 3 is fixedly inserted into the movable comb tooth groove 5, and an adjusting handwheel 2 is provided at the end of the threaded rod 3. The threaded sleeve 7 is fixed in the positioning hole 11 of the fixed comb tooth groove 9. By rotating the adjusting handwheel 2, the threaded rod 3 rotates within the threaded sleeve 7, thereby driving the movable comb tooth groove 5 to move along the guide rail 15, realizing the adjustment of the distance between the two sets of comb tooth grooves to adapt to electrode plates of different sizes.

[0024] In one embodiment, both the fixed comb groove 9 and the movable comb groove 5 are provided with retractable comb grooves 10 on their sides, which can be stretched or contracted. Both the fixed comb groove 9 and the movable comb groove 5 have internal drawer slots for the retractable comb groove 10 to extend and retract; slide rails are provided at the upper and lower ends of the drawer slots, and the retractable comb groove 10 is pulled out via ball bearing slide rails 12. The ball bearing slide rails 12 have a strong load-bearing capacity, meeting the heavy load requirements of the electrolytic cell plates. The friction during ball rolling is relatively small, ensuring smooth movement even under heavy loads, reducing wear, and extending service life. Each of the retractable comb grooves 10 has a handle 14 at its outer end. When it is necessary to expand the storage space, the retractable comb groove 10 can be pulled out to both sides of the fixed comb groove 9 and the movable comb groove 5. The retractable comb groove 10 is also evenly provided with comb-shaped slots 8, which can greatly increase the number of plates that can be stored. When not in use, the retractable comb groove 10 can be retracted into the pull-out slot, without taking up space.

[0025] In one embodiment, both ends of the fixed comb groove 9 and the movable comb groove 5 are provided with first pin holes 4, and the inner end of the pull-out comb groove 10 is provided with a second pin hole 6. The first pin hole 4 and the second pin hole 6 are fixed by a pin 17. When the pull-out comb groove 10 is pulled outward to its final position, the pin 17 is manually or simultaneously inserted into the first pin hole 4 and the second pin hole 6 using an electric or pneumatic device, so that the pull-out comb groove 10 is firmly connected to the fixed comb groove 9 / movable comb groove 5, restricting its movement. This fixing method is convenient to operate, and the status of the pin is intuitive, facilitating daily maintenance and repair by staff. Moreover, this method can provide strong fixing force, which can effectively prevent the pull-out part from sliding due to external forces after the electrode plate is placed, ensuring the safety of the device.

[0026] The movable pulley system includes a combination of a set of directional wheels 13 and a set of universal wheels 16. After the electrode plate is placed in the comb groove, the entire fixing device relies on the combination of directional wheels 13 and universal wheels 16 at the bottom of the fixed base plate 1 to realize the flexible transfer of the electrolytic cell electrode plate between various processing lines in the production workshop, such as from the electrode plate electroplating line to the electrolytic cell assembly line.

[0027] Compared to traditional stacking methods, the movable design of this invention effectively avoids the risk of deformation of the lower electrode plates due to heavy pressure, while also preventing coating wear caused by electrode plate stacking, significantly reducing the scrap rate of the electrode plates. Furthermore, the innovative device of this invention adopts a hidden, retractable comb-tooth groove design, expanding the storage space for the electrode plates while maintaining the original floor space, effectively improving the space utilization and practical performance of the device.

[0028] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
