Description

Technical Field

[0001] This utility model relates to the technical field of nickel-cadmium battery production, specifically to a filling device for nickel-cadmium battery production that facilitates the batch addition of electrolyte. Background Technology

[0002] Nickel-cadmium batteries have excellent performance and a wide range of applications. Filling equipment is used in the production of nickel-cadmium batteries. Before biochemical treatment, the electrolyte is filled into the nickel-cadmium battery through the filling equipment. Currently, there are many types of filling equipment for nickel-cadmium batteries on the market.

[0003] However, a utility model patent with authorization announcement number CN212448985U discloses a novel lithium-ion electrolyte filling device, belonging to the field of electrolyte filling technology. It includes a tank, a right-side fixing plate, a right-side top fixing plate, and a power interface. The right-side fixing plate is located on the upper right side of the tank, and the tank is fixedly connected to the right-side fixing plate. The right-side top fixing plate is located on the upper right side of the tank. This novel lithium-ion electrolyte filling device, through structural improvements, makes it easier to prevent electrolyte residue from remaining at the bottom of the tank during actual use. The inclusion of a guide plate and a feed pipe interface simplifies tank cleaning when changing to different types of electrolyte, reducing workload and electrolyte waste. Furthermore, the inclusion of a stirrer fixing rod and a stirrer prevents electrolyte sedimentation inside the tank when the device is not running, thus avoiding inconsistent electrolyte concentration within the tank. This device is highly practical.

[0004] The existing technical solutions described above have the following drawbacks: the stirrer is located at the upper part of the tank, which means that the stirrer cannot reach the middle and lower parts of the tank, resulting in insufficient stirring. This causes the electrolyte in the tank to easily settle, leading to inconsistent electrolyte concentration. Moreover, the existing solutions generally add electrolyte one battery at a time, which is inefficient. In addition, the existing solutions require placing the batteries on a mobile cart, which may move during electrolyte filling, causing the batteries to tilt and the electrolyte to spill out, resulting in waste. Therefore, we propose a filling device for nickel-cadmium battery production that facilitates batch addition of electrolyte to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a filling device for nickel-cadmium battery production that facilitates the batch addition of electrolyte, in order to solve the problems of the filling devices for nickel-cadmium battery production mentioned in the background art, which are inconvenient to fully stir, the electrolyte in the tank is prone to precipitation leading to inconsistent electrolyte concentration, and are not convenient for batch addition of electrolyte, resulting in low efficiency. At the same time, the position of the moving frame is prone to tilting.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a filling device for the production of nickel-cadmium batteries that facilitates the batch addition of electrolyte, comprising a support frame, a tank for storage fixedly connected to the upper end of the support frame, and round tubes inlaid at equal intervals on the upper left end of the support frame.

[0007] Also includes:

[0008] The tank body is equipped with a stirring structure and a batch liquid addition structure on its interior and left side. The stirring structure includes a connecting shaft, a motor, a connecting rod, a stirring rod, and stirring blades. The batch liquid addition structure includes a transition box, a liquid injection pipe, a mounting plate, an adjusting rod, an adjusting plate, a limiting plate, and a connection port.

[0009] The inside of the circular tube is magnetically connected to a magnetic column, and the magnetic columns are equally spaced and embedded in the upper right end of the movable frame.

[0010] Preferably, the connecting shaft is rotatably connected inside the tank, and a motor is installed at the upper end of the connecting shaft, while connecting rods are fixedly connected to the bottom end of the connecting shaft symmetrically on both sides.

[0011] Preferably, the outer end of the connecting rod is inlaid with a stirring rod, and the outer end of the stirring rod fits into the inner wall of the tank. The stirring rod and the stirring blade are in a rotating structure inside the tank through the connecting shaft, wherein the stirring blade is inlaid at equal angles on the outer surface of the connecting shaft.

[0012] Preferably, a first infusion pipe is fixedly connected to the bottom end of the tank, and an infusion pump is bolted to the lower end of the first infusion pipe, and a second infusion pipe is bolted to the upper end of the infusion pump.

[0013] The upper end of the second infusion tube is bolted to the upper end of the transition box, and the transition box is fixedly connected to the lower end of the mounting bracket. The right end of the mounting bracket is embedded in the upper left end of the tank.

[0014] Preferably, the bottom of the transition box is inclined, and the bottom of the transition box is connected to a liquid injection tube at equal intervals by threads, and the position of the liquid injection tube corresponds one-to-one with the position of the liquid filling port on the upper end of the nickel-cadmium battery on the upper end of the moving frame.

[0015] Preferably, the lower end of the movable frame is symmetrically inlaid with mounting plates, and an adjusting rod is rotatably connected to the mounting plates. The outer surface of the adjusting rod has a bidirectional threaded structure, and the adjusting plates are symmetrically threaded onto the adjusting rod.

[0016] Preferably, the adjusting plate is nested inside the connecting port, and the connecting port is symmetrically opened on the movable frame. The upper end of the adjusting plate is integrally connected to the lower middle position of the limiting plate, and the limiting plate has a sliding structure at the upper end of the movable frame through the adjusting plate and the adjusting rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the filling device for cadmium-nickel battery production that facilitates batch addition of electrolyte is convenient for thorough stirring, prevents electrolyte precipitation in the tank from causing inconsistent electrolyte concentration, facilitates batch addition of electrolyte, improves efficiency, and avoids the position of the moving frame from becoming skewed.

[0018] 1. Equipped with a stirring rod and stirring blades, the structural design of the stirring rod and stirring blades inside the tank allows the stirring rod and stirring blades to stir the electrolyte inside the tank when they rotate, thereby facilitating thorough stirring and preventing electrolyte precipitation inside the tank, which would lead to inconsistent electrolyte concentration;

[0019] The outer end of the stirring rod fits into the inner wall of the tank, so that when the left and right stirring rods rotate, they scrape the inner wall of the tank, and the electrolyte will not stick to the inner wall and be wasted.

[0020] 2. It is equipped with an injection tube and a limiting plate. The structural design of the limiting plate at the upper end of the moving frame allows the adjusting rod to be rotated when multiple nickel-cadmium batteries are placed at the upper end of the moving frame, so that the adjusting plate can slide inward inside the connection port when the adjusting rod is rotated.

[0021] Until the symmetrically arranged limiting plates abut against the outer wall of the nickel-cadmium battery, the bottom of the transition box is connected to the liquid injection tube with equally spaced threads, so that the electrolyte inside the transition box can be added to the nickel-cadmium battery in the corresponding position through the liquid injection tube, thereby facilitating the batch addition of electrolyte and improving efficiency.

[0022] 3. It is equipped with magnetic pillars and round tubes. The inside of the round tubes is magnetically connected to the magnetic pillars. When the moving frame moves to the left side of the support frame, the magnetic pillars, which are set at equal intervals, are engaged inside the round tubes at the corresponding positions, thereby preventing the moving frame from tilting.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6 This utility model provides a technical solution: a filling device for the production of nickel-cadmium batteries that facilitates the batch addition of electrolyte, including a support frame 1, a tank 2, a connecting shaft 3, a motor 4, a connecting rod 5, a stirring rod 6, a stirring blade 7, a first infusion pipe 8, an infusion pump 9, a second infusion pipe 10, a transition box 11, a mounting frame 12, an injection pipe 13, a moving frame 14, a magnetic column 15, a round pipe 16, a mounting plate 17, an adjusting rod 18, an adjusting plate 19, a limiting plate 20, and a connecting port 21.

[0032] Example 1: Existing methods require placing the battery on a mobile cart. However, the cart may shift during electrolyte filling, causing the battery to tilt and electrolyte to spill out, resulting in waste. Therefore, this example addresses this issue with the following technical solution: Figure 1 , Figure 5 and Figure 6 Since the inside of the circular tube 16 is magnetically connected to the magnetic pillars 15, and the magnetic pillars 15 are equally spaced and embedded in the upper right end of the movable frame 14, the movable frame 14 is pushed to move to the left side of the support frame 1, so that the equally spaced magnetic pillars 15 are engaged in the equally spaced circular tube 16. The circular tube 16 is made of iron, so the magnetic pillars 15 can be magnetically connected to the inside of the circular tube 16. The position of the movable frame 14 on the left side of the support frame 1 is limited by the magnetic pillars 15 and the circular tube 16, thereby preventing the position of the movable frame 14 from being skewed.

[0033] Example 2: Existing stirrers are located at the upper part of the storage tank, resulting in insufficient stirring in the middle and lower parts of the tank. This inadequate stirring causes the electrolyte in the storage tank to easily precipitate, leading to inconsistent electrolyte concentrations. Therefore, this example uses the following technical solution: Figure 1 The stirring structure includes a connecting shaft 3, a motor 4, a connecting rod 5, a stirring rod 6, and stirring blades 7. The connecting shaft 3 has connecting rods 5 fixedly connected symmetrically to its bottom end. The outer end of the stirring rod 6 fits into the inner wall of the tank 2. The stirring rod 6 and stirring blades 7 rotate within the tank 2 via the connecting shaft 3. Therefore, when the motor 4 operates, it drives the connecting shaft 3 to rotate within the tank 2. The rotation of the connecting shaft 3 drives the symmetrically arranged connecting rods 5 and stirring rods 6, as well as the stirring blades 7 arranged at equal angles, to rotate. This ensures that the symmetrically arranged stirring rods 6 and stirring blades 7, along with the equally spaced stirring blades 7, thoroughly stir the electrolyte inside the tank 2. Furthermore, the symmetrically arranged stirring rods 6 can scrape away the electrolyte from the inner wall of the tank 2 during rotation, preventing electrolyte from adhering to the inner wall and wasting resources. This facilitates thorough stirring and prevents electrolyte precipitation within the tank 2, which could lead to inconsistent electrolyte concentrations.

[0034] Example 3: Existing methods typically add batteries one by one, which is inefficient. Therefore, this example uses the following technical solution, such as... Figure 1-6The batch liquid filling structure includes a transition box 11, a liquid injection pipe 13, a mounting plate 17, an adjusting rod 18, an adjusting plate 19, a limiting plate 20, and a connecting port 21. The bottom of the transition box 11 is threaded with the liquid injection pipe 13 at equal intervals. The position of the liquid injection pipe 13 corresponds one-to-one with the position of the liquid filling port on the upper end of the nickel-cadmium battery on the moving frame 14. The outer surface of the adjusting rod 18 has a bidirectional threaded structure. The adjusting plate 19 is nested inside the connecting port 21. The limiting plate 20 slides on the upper end of the moving frame 14 via the adjusting plate 19 and the adjusting rod 18. Therefore, multiple nickel-cadmium batteries are placed on the upper end of the moving frame 14, with the lower end of the last nickel-cadmium battery flush with the front end of the rear connecting port 21, and the lower end of the foremost nickel-cadmium battery flush with the rear end of the front connecting port 21. The adjusting rod 18 is rotated to adjust the position of the battery in the mounting position. Rotating the plate 17 causes the symmetrically arranged adjusting plates 19 to slide inward within the corresponding connection ports 21, bringing the two sets of limiting plates 20 closer together until they abut against the outer wall of the nickel-cadmium battery. This prevents the nickel-cadmium battery from moving on the moving frame 14 and causing deviation between the filling port and the injection pipe 13. When the infusion pump 9 is working, it draws the electrolyte from inside the tank 2 into the second infusion pipe 10 through the first infusion pipe 8. The electrolyte then enters the transition box 11 through the second infusion pipe 10. After the electrolyte in the transition box 11 is filled, the infusion pump 9 stops working, and the control valves on the equally spaced injection pipes 13 open simultaneously. The electrolyte in the transition box 11 is then added to the nickel-cadmium battery in the corresponding position through the equally spaced injection pipes 13, thus facilitating batch addition of electrolyte and improving efficiency.
