Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, specifically a high-efficiency anti-sedimentation storage tank stirring device. Background Technology

[0002] Nickel carbonate is an important inorganic compound, appearing as a green powder or crystal. It is widely used in the manufacture of nickel-based batteries, the preparation of catalysts, the formulation of high-temperature ceramic materials, and the electroplating industry, making it an indispensable raw material in the chemical industry. Due to the stable physical and chemical properties of nickel carbonate, coupled with its increasing industrial demand, the efficiency and stability of its production process are of great significance to the development of downstream industries.

[0003] In the production of nickel carbonate, a reaction precipitation method is typically used. This involves mixing a nickel salt solution with a sodium carbonate solution to generate a nickel carbonate precipitate, which is then filtered, washed, and dried to obtain the finished product. After precipitation, the reaction solution must be stored in a dedicated tank for subsequent filtration or further reactions. However, because nickel carbonate contains solid particles and its density is higher than that of a liquid medium, the particles tend to settle to the bottom of the tank due to gravity during storage, forming a solid precipitate layer. This precipitation phenomenon poses a significant challenge to the stability and efficiency of the production process.

[0004] Traditional nickel carbonate production storage tanks are typically equipped with agitators to prevent sediment formation. However, due to the limited flow patterns of the liquid inside the tank, the coverage area of ​​traditional agitators is limited, especially at the bottom of the tank where dead zones can easily form, making it difficult to completely eliminate particle deposition and potentially clogging equipment pipelines. In view of this, we propose a highly efficient anti-sedimentation storage tank agitator. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency anti-sedimentation tank stirring device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-efficiency anti-precipitation storage tank stirring device includes a storage tank for storing a reaction liquid containing nickel carbonate, wherein the storage tank is equipped with a stirring element, which achieves high-efficiency stirring through rotation and liquid circulation to prevent nickel carbonate particles from settling.

[0008] The stirring component includes a circular hollow shell. A rotating vertical rod is rotatably connected to the center of the bottom of the circular hollow shell via a first sealed bearing. The first sealed bearing supports the rotating vertical rod and ensures its stable operation. The outer wall of the rotating vertical rod is provided with multiple stirring blades arranged at equal intervals. The stirring blades are used to stir the liquid and particles inside the storage tank, prevent particle sedimentation, and promote uniform mixing of the liquid.

The top of the mounting plate is provided with a pump body. The pump body is connected to an external power supply and controller. The input end of the pump body is connected to the discharge pipe through a liquid suction pipe. The liquid suction pipe is used to transport liquid in the conical cavity to the pump body.

[0012] Preferably, the outer wall of the circular hollow shell is provided with three connecting rods arranged in a ring array. The end of the connecting rod away from the circular hollow shell is fixedly connected to the inner wall of the storage tank to ensure the stability of the stirring component.

[0013] Preferably, a second sealed bearing is provided at the top of the outer wall of the rotating vertical rod. The first and second sealed bearings can prevent the solution from entering the bearing and improve the service life of the first and second sealed bearings. The top of the outer ring of the second sealed bearing is fixedly connected to the top of the inner wall of the circular hollow shell, thereby improving the rotational stability of the rotating vertical rod.

[0014] Preferably, the rotating guide vane is located inside a circular hollow shell, and an impact groove is provided on the side of the rotating guide vane to enhance the effect of liquid impacting the rotating guide vane.

[0015] Preferably, the drain pipe is provided with a first valve, which is used to control the flow rate of liquid discharged from the conical cavity and to control the opening and closing of the drain pipe.

[0016] Preferably, the connection between the inlet pipe and the circular hollow shell is located near the rear end of the outer wall of the circular hollow shell, ensuring that the solution output from the outlet of the inlet pipe can impact the rearmost rotating guide vane, thereby causing the water flow to impact the rotating guide vane and drive it to rotate.

[0017] Preferably, the liquid guide pipe is provided with a second valve, which is used to control the flow rate of liquid to the circular hollow shell and to control the opening and closing of the liquid guide pipe. The liquid outlet pipe is provided with a third valve, which is used to control the flow rate of liquid discharged from the storage tank and to control the opening and closing of the liquid outlet pipe. Only one of the second and third valves is open during use. When stirring, the third valve is closed and the second valve is open. When discharging liquid, the third valve is open and the second valve is closed.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This high-efficiency anti-sedimentation storage tank stirring device, by setting up a stirring component, has rotating guide vanes that rotate with the liquid flow, driving the rotating vertical rod and stirring blades to rotate synchronously. The stirring blades can stir the liquid in the storage tank, preventing particles from settling at the bottom of the storage tank due to gravity, and ensuring that nickel carbonate particles are evenly distributed. Through the circulation design of the pump body, drain pipe, inlet pipe, guide pipe and outlet hole, the liquid inside the storage tank forms a continuous circulation flow, which effectively solves the particle deposition and dead zone problems of traditional storage tank stirring devices mentioned in the background technology.

[0020] 2. This high-efficiency anti-sedimentation tank stirring device features a conical cavity at the bottom of the tank, which avoids the problem of dead corners that cannot be covered at the bottom in traditional stirring devices. After the liquid and particles are collected in the conical cavity, they enter the pump body through the drain pipe and circulate back to the stirring components, ensuring that the particles at the bottom of the tank can also be fully stirred.

[0021] 3. This high-efficiency anti-sedimentation storage tank stirring device, through the setting of the first valve, the second valve and the third valve, realizes the flexible switching between circulating stirring and discharge for use of liquid. In stirring mode, the third valve is closed and the second valve is opened to ensure that the liquid can circulate into the stirring element; while in discharge mode, the second valve is closed and the third valve is opened to realize the discharge of liquid. The simple control method makes it easy for operators to adjust the working status of the device according to their needs. Attached Figure Description
