Description

Technical Field

[0001] This utility model relates to the field of electrolysis technology, specifically to a small electrolytic cell. Background Technology

[0002] Traditional small electrolyzers typically employ a simple pipe-based inlet design, lacking effective flow guiding and diversion devices. When the electrolyte enters the tank through a single inlet, a localized high-velocity region tends to form near the inlet, while the flow rate is slow or even static dead zones appear in areas far from the inlet. This uneven flow rate distribution leads to significant differences in electrolyte concentration gradients within the tank. Areas near the electrodes are prone to "lean electrolyte" due to rapid consumption of reactants, while areas far from the electrodes suffer from reduced reaction utilization due to the inability to replenish reactants in a timely manner. Furthermore, the uneven fluid state can also cause uneven current distribution on the electrode surface, leading to localized over-reactions and the production of byproducts, affecting product purity and severely limiting the overall efficiency of the electrolysis reaction.

[0003] If the gaseous or liquid products generated by the electrolysis reaction are not collected in a timely and efficient manner, not only will product loss occur, but the fluid state and reaction environment within the tank may also be affected. Traditional small electrolyzers often use top overflow or simple side evacuation for product collection, lacking a structural design for directional guidance and centralized collection. For gaseous products, the bubbles formed in the electrolyte are prone to random diffusion, and some bubbles may break during their ascent or adhere to the tank wall and cannot be effectively captured. For liquid products, they are prone to mixing with the electrolyte to form a homogeneous system, making it difficult to achieve effective separation using traditional collection methods. In addition, if some products remain in the tank for a long time, they may undergo secondary reactions with the electrolyte or electrodes, leading to a decrease in product purity and further reducing collection efficiency and product quality. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a small electrolytic cell, which solves the problem that if the gaseous or liquid products generated by the electrolysis reaction cannot be collected in a timely and efficient manner, it will not only cause product loss, but may also affect the fluid state and reaction environment in the cell. Traditional small electrolytic cells mostly use top overflow or simple side suction to collect products, lacking a structural design for directional guidance and centralized collection. For gaseous products, the bubbles formed in the electrolyte are prone to random diffusion, and some bubbles may break during the rise or adhere to the cell wall and cannot be effectively captured.

[0005] According to one aspect, at least one embodiment of the present invention provides a small electrolytic cell, including... The tank body has a liquid inlet tank on its side wall; A diversion and collection assembly is disposed inside the tank; A cleaning component is disposed at the inner bottom of the tank. The flow collection assembly includes a collection hood, which is disposed on the inner side wall of the tank. A flow guide slope is provided at the end of the collection hood. A drive shaft is provided on the inner side wall of the tank. A flow guide shaft is provided on the drive shaft. A flow guide plate is provided on the outer side wall of the flow guide shaft.

[0006] For example, the diversion and collection assembly provided in at least one embodiment of the present invention further includes a drive gear; One end of the drive shaft extends out of the groove, the drive gear is disposed at the end of the drive shaft, and a connecting gear is disposed on the drive gear, and the drive gear and the connecting gear mesh with each other.

[0007] According to another aspect, at least one embodiment of the present invention also provides a cleaning assembly, including a cleaning shaft; The cleaning shaft is disposed on the inner side wall of the tank, and a cleaning sleeve is disposed at the end of the cleaning shaft. A cleaning blade is disposed on the outer side wall of the cleaning sleeve. A cleaning port is disposed on the side wall of the tank, and the cleaning blade is positioned corresponding to the cleaning port.

[0008] For example, the cleaning assembly provided in at least one embodiment of this utility model further includes a pressurized arc-shaped plate; The pressure-boosting arc-shaped plate is disposed on the lower end face of the collection hood, and a pressure-boosting port is formed between the pressure-boosting arc-shaped plate and the inner bottom of the trough.

[0009] As a further technical solution, a flow guide plate is provided inside the tank, the flow guide plate is parallel to the collection hood, and the flow guide plate is located on the upper end face of the collection hood.

[0010] As a further technical solution, the inner bottom surface of the liquid inlet tank is provided with a liquid inlet, and a liquid inlet pipe is connected to the liquid inlet.

[0011] As a further technical solution, the connecting gear is provided with a connecting shaft, and the connecting shaft is provided with a drive chain.

[0012] As a further technical solution, the drive shaft and the diverter shaft are fixedly connected by a key pin.

[0013] The beneficial effects of this utility model are as follows: In this invention, through the coordinated design of the funnel-shaped inlet tank and the guide plate directly above the collection hood, the electrolyte is collected in the inlet tank and then evenly distributed to the core reaction area of ​​the tank by the guide plate. This effectively avoids problems such as uneven local flow rate and static dead zones caused by traditional single inlet ports, ensuring that the electrolyte concentration gradient in the tank tends to be gentle and eliminating the "liquid-deficient" phenomenon near the electrodes. The opening of the collection hood faces the center of the tank, and with the disturbance and guiding effect of the flow deflector, the gaseous or liquid products generated by the electrolysis reaction can flow directionally to the collection hood. The guide slope at the end of the collection hood guides the products to be quickly and concentratedly discharged, avoiding the problems of random diffusion and adhesion of products to the tank wall in traditional collection methods.

[0021] like Figures 1-3 As shown, it illustrates a small electrolytic cell according to one embodiment of the present invention, including... Tank 1, with a liquid inlet tank 2 provided on the side wall of tank 1; The diversion and collection component 3 is disposed inside the tank 1; Cleaning component 4 is disposed at the bottom of the tank 1. This embodiment provides a flow-diverting and collecting assembly 3. A collecting cover 3-1 is installed on the inner wall of the tank 1. A guide slope 3-2 is provided at the end of the collecting cover 3-1. A drive shaft 3-3 is provided on the inner wall of the tank 1, and a flow-diverting shaft 3-4 is installed on the drive shaft 3-3. Flow-diverting plates 3-5 are provided on the outer wall of the flow-diverting shaft 3-4. This allows the rectangular tank 1 to be formed by thermal welding of the various plates. At predetermined positions on the side wall of the tank 1, mounting holes matching the diameter of the inlet tank 2 are drilled using drilling equipment. Then, the liquid inlet trough 2 is tightly embedded into the hole and sealed with sealant to ensure no leakage at the connection. The collection hood is formed by stamping and the surface is polished to reduce resistance. The collection hood 3-1 is fixed to the inner side wall of the tank 1 with bolts, ensuring that the opening of the collection hood 3-1 faces the center of the tank 1 and the installation angle is at a certain angle with the side wall of the tank 1 to maximize the collection efficiency. The guide slope 3-2 at the end of the collection hood 3-1 is integrally formed with the collection hood 3-1 by welding. The guide slope 3-2 is set with a certain slope to ensure that the collected material can slide down smoothly.

[0022] Two seated bearings are installed at corresponding positions on the inner side wall of the tank 1. The drive shaft 3-3 passes through the inner ring of the bearing to ensure that the drive shaft 3-3 can rotate flexibly. One end of the drive shaft 3-3 extends out of the tank 1, and a keyway is machined on the extended part for mounting the drive gear 3-6. The part of the drive shaft 3-3 located inside the tank 1 is connected to the diverting shaft 3-4 by a key pin. Multiple diverting plates 3-5 are evenly welded on the diverting shaft 3-4. The diverting plates 3-5 are rectangular or trapezoidal in shape. The welding angle between the diverting plates 3-5 and the diverting shaft 3-4 is a certain angle so that the diverting plates 3-5 can effectively disturb the electrolyte when rotating.

[0023] A rectangular cleaning port 4-4 is made on the side wall of tank 1 at the position corresponding to the rotation trajectory of the cleaning slurry 4-3. The length of the cleaning port 4-4 is slightly larger than the length of the cleaning slurry 4-3. A detachable sealing door is installed at the cleaning port 4-4. The sealing door is sealed with a sealing strip to ensure that there is no electrolyte leakage when the electrolytic cell is working normally.

[0024] The pressure-boosting arc plate 4-5 is fixed to the lower end face of the collection cover 3-1 by welding or bolt connection. The bending direction of the pressure-boosting arc plate 4-5 is towards the bottom of the tank 1. The distance between the pressure-boosting arc plate 4-5 and the bottom of the tank 1 is adjusted according to actual needs. The width of the pressure-boosting port 4-6 formed is set according to needs to increase the flow rate of electrolyte at this point and improve the material collection effect.

[0025] refer to Figure 1 and Figure 3 In some embodiments, the diversion and collection assembly 3 further includes drive gears 3-6; One end of the drive shaft 3-3 extends out of the groove 1. The drive gear 3-6 is located at the end of the drive shaft 3-3. A connecting gear 3-7 is provided on the drive gear 3-6. The drive gear 3-6 and the connecting gear 3-7 mesh with each other.

[0026] In some examples, the drive gear 3-6 is tightly mounted on one end of the drive shaft 3-3 extending from the groove 1 by a flat key to ensure the concentricity of the gear and the shaft. The connecting gear 3-7 is mounted at the position that meshes with the drive gear 3-6, and the center distance between the two is precisely calculated based on the gear module and the number of teeth.

[0027] like Figures 1-3 As shown, on the other hand, the present invention also provides a cleaning component 4, including a cleaning shaft 4-1; In some examples, the cleaning shaft 4-1 is provided on the inner side wall of the tank 1, the end of the cleaning shaft 4-1 is provided with a cleaning sleeve 4-2, the outer side wall of the cleaning sleeve 4-2 is provided with a cleaning blade 4-3, the side wall of the tank 1 is provided with a cleaning port 4-4, and the cleaning blade 4-3 and the cleaning port 4-4 are positioned corresponding to each other.

[0028] refer to Figure 1 and Figure 3 In some embodiments, the cleaning component 4 further includes pressurized arc-shaped plates 4-5; A pressure-boosting arc-shaped plate 4-5 is disposed on the lower end face of the collection cover 3-1, and a pressure-boosting port 4-6 is formed between the pressure-boosting arc-shaped plate 4-5 and the inner bottom of the tank 1.

[0029] In some examples, two seated bearings are installed on the inner wall of the tank 1 near the bottom. The cleaning shaft 4-1 passes through the inner ring of the bearings, making the cleaning shaft 4-1 parallel to the bottom of the tank 1 and maintaining a certain distance from the drive shaft 3-3 to prevent mutual interference. One end of the cleaning shaft 4-1 can extend out of the tank 1 to connect to an external drive device. After the cleaning sleeve 4-2 is fitted onto the cleaning shaft 4-1, it is fixed with a set screw or clamp to ensure that the cleaning sleeve 4-2 rotates synchronously with the cleaning shaft 4-1. Multiple cleaning blades 4-3 are evenly distributed on the outer wall of the cleaning sleeve 4-2. The cleaning blades 4-3 are fan-shaped and are fixed to the cleaning sleeve 4-2 by bolts or welding. The gap between the edge of the blade and the bottom of the tank 1 is controlled within a small range, which can effectively scrape off the deposits without excessively abrading the bottom of the tank 1.

[0030] For example, such as Figure 2 As shown, a flow guide plate 5 is provided inside the tank 1. The flow guide plate 5 is parallel to the collection cover 3-1 and is located on the upper surface of the collection cover 3-1.

[0031] In some examples, the diversion plate 5 is a rectangular flat plate, which is horizontally fixed inside the tank 1 using bolts or clips, located directly above the collection hood 3-1 and parallel to it. The distance between the two is determined according to the requirements. The length and width of the diversion plate 5 are determined according to the internal dimensions of the tank 1, and should be able to cover most of the area above the collection hood 3-1 to ensure that the electrolyte can flow evenly to the collection hood 3-1.

[0032] For example, such as Figure 2 As shown, the inner bottom surface of the liquid inlet tank 2 is provided with a liquid inlet 6, and a liquid inlet pipe 7 is connected to the liquid inlet 6.

[0033] In some examples, the inlet tank 2 is designed in the shape of a funnel to facilitate the rapid flow of electrolyte. A circular inlet port 6 is precisely machined at the center of the bottom surface of the inlet tank 2. The inner diameter of the inlet port 6 is determined according to the required inlet flow rate. The inlet pipe 7 is made of a pipe material resistant to electrolyte corrosion and is firmly connected to the inlet port 6 through a threaded joint or quick-connect joint. A flow control valve and a flow meter are installed on the inlet pipe 7 to accurately control and monitor the inflow of electrolyte.

[0034] For example, such as Figure 3 As shown, a connecting shaft 8 is provided on the connecting gear 3-7, and a drive chain 9 is provided on the connecting shaft 8.

[0035] In some examples, a drive chain 9 is installed on the connecting shaft 8, and the chain is connected to an external power unit. The speed and torque of the power unit are selected according to the required flow rate and stirring force.

[0036] For example, such as Figure 2 As shown, the drive shaft 3-3 and the diverter shaft 3-4 are fixedly connected by a key pin.

[0037] In some examples, the center hole of the connecting gear 3-7 is connected to the connecting shaft 8 by a key, and the two ends of the connecting shaft 8 are also supported by bearings with mounting brackets.

[0038] In use, this small electrolyzer achieves stable electrolyte supply, efficient electrolysis reaction, directional product collection, and convenient maintenance of the tank body 1 through the synergistic effect of the tank body 1, the diversion and collection component 3, the treatment and cleaning component 4, and other auxiliary components. The core working logic revolves around four stages: "fluid regulation - reaction enhancement - product collection - cleaning assurance".

[0039] I. Electrolyte Supply and Conduction Stage Electrolyte input: External electrolyte is delivered to the inlet tank 2 on the side wall of tank 1 through inlet pipe 7. The flow control valve on inlet pipe 7 can precisely adjust the inflow rate of electrolyte according to the requirements of electrolysis reaction. The flow meter provides real-time feedback of flow data to ensure that the inlet volume is stable and controllable.

[0040] Uniform flow guidance: The funnel-shaped design of the inlet tank 2 guides the electrolyte to quickly gather and enter the tank 1 through the inlet 6. At this time, the guide plate 5 located directly above the collection hood 3-1 plays a role in distributing the incoming electrolyte evenly to the area of ​​the collection hood 3-1, avoiding local electrolyte accumulation or uneven flow rate, and providing a uniform fluid environment for the subsequent electrolysis reaction.

[0041] II. Current Disturbance and Electrolysis Reaction Enhancement Stage Power transmission: An external power unit (such as a motor) drives the connecting shaft 8 to rotate through the drive chain 9. The connecting gear 3-7 on the connecting shaft 8 meshes with the drive gear 3-6 at the end of the drive shaft 3-3, transmitting power to the drive shaft 3-3. Since the drive shaft 3-3 and the diverting shaft 3-4 are fixedly connected by a key pin, the diverting shaft 3-4 rotates synchronously with the drive shaft 3-3.

[0042] Electrolyte disturbance: When the deflector 3-5 on the deflector shaft 3-4 rotates with the shaft, it continuously disturbs the electrolyte in the tank 1, breaking the static distribution of the electrolyte and increasing the contact frequency and contact area between the electrolyte and the electrode (which requires additional configuration and is not mentioned in the figure). At the same time, the deflector effect can accelerate the diffusion of reaction products on the electrode surface, avoid the accumulation of products on the electrode surface which leads to a decrease in reaction efficiency, thereby enhancing the overall electrolysis reaction rate.

[0043] III. Product Collection and Flow Rate Pressurization Stage Directed collection of products: The gaseous (such as hydrogen, oxygen) or liquid products generated by the electrolysis reaction flow towards the inner wall of the tank 1 under the disturbance of the flow deflector 3-5, and are finally captured by the collection hood 3-1 with the opening facing the center of the tank 1. The shape design of the collection hood 3-1 can guide the products to converge along its inner wall to the end.

[0044] Product guidance and discharge: The guide slope 3-2 at the end of the collection hood 3-1 is designed with an inclined angle so that the collected product slides down the slope naturally, which is convenient for subsequent directional discharge of the product through the pipe (additional configuration required) to the tank 1, thus achieving efficient collection of the product.

[0045] Flow rate boosting assistance: The boosting arc plate 4-5 on the lower end face of the collection hood 3-1 forms a narrow boosting port 4-6 with the bottom of the tank 1. When the electrolyte flows through this port, the flow cross section is reduced, and according to the principle of fluid mechanics, the electrolyte flow rate will be significantly increased. The high-speed flowing electrolyte can enhance the carrying capacity of the product in the collection hood 3-1, and further improve the product collection efficiency.

[0046] IV. Tank 1 Cleaning and Maintenance Phase Cleaning power drive: The cleaning shaft 4-1 can be driven to rotate by an external drive device (independent or linked with the diversion system). Since the cleaning sleeve 4-2 is fixed to the cleaning shaft 4-1 by a set screw or clamp, the cleaning sleeve 4-2 rotates synchronously with the cleaning shaft 4-1.

[0047] Deposits scraping and pushing: The fan-shaped cleaning blade 4-3 on the outside of the cleaning sleeve 4-2 comes into close contact with the bottom of the tank 1 during rotation, scraping away impurities and waste deposited at the bottom of the tank during the electrolysis reaction. As the cleaning blade 4-3 continues to rotate, the scraped deposits are gradually pushed to the cleaning port 4-4 on the side wall of the tank 1.

[0048] Deposits discharge: Open the sealed door at cleaning port 4-4 to discharge the deposits pushed here directly into tank 1. The cleaning operation can be completed without stopping the machine, avoiding the accumulation of deposits from interfering with the electrolysis reaction and ensuring the long-term stable operation of the equipment.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
