Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery manufacturing technology, specifically relating to a device for quantitative liquid transfer in lead-acid batteries. Background Technology

[0002] In lead-acid batteries, the electrolyte plays a crucial role. The amount of electrolyte used has the following impact on the battery:

[0003] When there is an excess of electrolyte, the free space inside the battery may be reduced, leading to increased internal pressure and increasing the risk of battery explosion.

[0004] Excessive electrolyte can also accelerate the battery's self-discharge rate, shortening its storage life. In addition, excessive electrolyte may overflow from the battery, corroding the battery casing and reducing battery safety.

[0005] When the electrolyte is insufficient, the concentration of sulfuric acid inside the battery may increase, leading to increased internal resistance and decreased battery performance. Insufficient electrolyte may also cause the battery to overheat during charging, or even trigger thermal runaway. In addition, insufficient electrolyte will affect the battery's discharge capacity and cycle life, thus reducing battery performance.

[0006] Therefore, when using lead-acid batteries, it is necessary to confirm the amount of electrolyte added during battery production to ensure that the battery is in optimal working condition.

[0007] The traditional method of transferring electrolyte involves introducing the electrolyte into a container, weighing it, and then pouring it into the casing. This can cause errors in battery development experiments due to the weighing and transferring of electrolyte, and also increases the probability of the operator coming into contact with acid.

[0008] Therefore, how to provide a portable device for quantitative liquid transfer in lead-acid batteries is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0009] In view of this, the present invention provides a device for quantitative transfer of electrolyte in lead-acid batteries, which can reduce errors caused by weighing and transferring electrolyte in battery development experiments. It can also reduce liquid loss during the transfer process and decrease the probability of operator contact with acid, making it safer to use.

[0010] To achieve the above objectives, this utility model adopts the following technical solution: a device for quantitative liquid transfer in lead-acid batteries, comprising:

[0011] The housing has a controller connected to its outer side wall, and the top and bottom of the housing have clearance holes for pipe penetration.

[0012] A transition buffer container is placed inside the housing. The top and bottom of the transition buffer container are connected and communicated with a tube, which is adapted to slide within a clearance hole.

[0013] The valves are in two sets and are respectively connected to the pipes on the upper and lower sides of the transition buffer container, and each valve is connected to a lead pipe.

[0014] A weighing assembly is fixed to the inner bottom wall of the housing and is located between the transition buffer container and the inner bottom wall of the housing. The weighing assembly and the valve can be electrically connected to a controller.

[0015] The technical advantages of this invention are as follows: the transition buffer container is used to buffer acid, and the weighing component is used to weigh the transition buffer container and the acid inside it. It should be noted that this weighing result is a relative value, which can relatively accurately measure the released acid. This solution controls the liquid inlet and outlet states of the transition buffer container through a valve, and the values ​​are relatively accurate and reliable. Furthermore, the liquid in the transition buffer container is poured into the required place using a pipe. In addition, this product is controlled by a controller on the shell, making it more convenient to operate and use.

[0016] Preferably, the controller is equipped with a control panel and a display component, the display component being used to display the liquid weight in the transition buffer container and the valve opening / closing status.

[0017] The resulting technical effect is that the control panel allows for convenient operation, enabling control over the operating status of each component, and the display component provides real-time feedback on weighing information.

[0018] Preferably, a stabilizing spring is installed between the inner top of the housing and the transition buffer container.

[0019] The resulting technical effect is that a stabilizing spring can be added to stabilize the position of the transition buffer container inside the shell. However, when calculating the acid outflow, the pressure effect of the stabilizing spring on the transition buffer container needs to be revised. Therefore, this product only needs the relative outflow acid value.

[0020] Preferably, the inlet tube is a corrosion-resistant flexible tube, the inlet tube located above the housing is used to connect to the liquid pump, and the inlet tube located below the housing is used to drain the liquid.

[0021] The resulting technical effect is that the liquid pump can be connected through the inlet pipe on the top of the shell to inject liquid into the transition buffer container, and the liquid can be introduced into the target container that needs the liquid through the inlet pipe on the bottom of the shell.
