A mounting structure of a magnetic filter for a battery electrolyte of a new energy vehicle

Abstract

This utility model relates to the field of magnetic filter technology, specifically an installation structure for a magnetic filter for electrolyte in new energy vehicle batteries. The structure includes a magnetic filter body with a handle and uniformly distributed magnetic rods. An inlet pipe and a drain pipe are connected to the magnetic filter body. In this installation structure, when the electrolyte flow is low, the drive unit raises the sealed cylinder, creating a water storage space inside. Due to the small space, the electrolyte level rises, increasing the contact area with the magnetic rods, thus fully purifying the electrolyte, improving filtration efficiency, and increasing impurity adsorption. When the electrolyte flow is high, the drive unit lowers the sealed cylinder, exposing the through-hole of the insert rod. The electrolyte flows downwards through this hole, simultaneously releasing space in the magnetic filter body to ensure smooth electrolyte passage, accommodating a large amount of electrolyte, preventing clogging, and maintaining filtration continuity and stability.

Description

Technical Field

[0001] This utility model relates to the field of magnetic filter technology, specifically to an installation structure for a magnetic filter for electrolyte in new energy vehicle batteries. Background Technology

[0002] As a core component of new energy vehicles, the performance and stability of batteries directly determine the vehicle's range, power output, and lifespan. As the carrier of ion transport in the battery, the purity of the electrolyte plays a crucial role in the battery's performance. Any impurities mixed into the electrolyte may cause internal short circuits, reduce battery capacity, accelerate battery aging, and seriously affect the overall performance and safety of the battery.

[0003] A search revealed that Chinese patent CN117244684A proposes a magnetic filter rod mounting structure, comprising: a magnetic filter body, and a magnetic block, mounting rod, first threaded rod, nut, and locking mechanism. This facilitates the installation and fixing of the magnetic block and makes it easy to disassemble and replace the magnetic block later. This avoids the problem of the lower end of the traditional magnetic rod not being properly fixed, causing it to shift under the impact of water flow, and the nut being missed during installation, leading to its subsequent detachment.

[0004] However, it was found in the use of the above-mentioned existing technology that it cannot be flexibly adjusted according to changes in electrolyte flow rate. When the electrolyte flow rate is small, the internal space of the filter is relatively large, and the electrolyte flow rate is slow. Due to the limited contact area, it is difficult to fully exert the filtration effect, resulting in some impurities not being effectively adsorbed. When the electrolyte flow rate increases, the fixed structure filter is prone to clogging, which not only affects production efficiency but may also cause the entire production process to be interrupted, requiring frequent shutdowns for cleaning and maintenance, increasing production costs and time costs. Therefore, we propose an installation structure for a magnetic filter for electrolyte in new energy vehicle batteries. Utility Model Content

[0005] To solve the above technical problems, this application provides an installation structure for a magnetic filter for electrolyte in new energy vehicle batteries, including a magnetic filter body, a handle on the magnetic filter body, uniformly distributed magnetic rods on the handle, and an inlet pipe and a drain pipe connected to the magnetic filter body respectively.

[0006] It also includes a closed cylinder, which is slidably connected to the magnetic filter body, and the magnetic rod passes through the closed cylinder and extends to the bottom of the closed cylinder;

[0007] The magnetic filter body is provided with a driving unit, which is used to drive the closed cylinder to move up and down within the magnetic filter body.

[0008] In some embodiments, the top of the closed cylinder has an opening, forming an open structure.

[0009] In some embodiments, the drive unit includes a push rod motor disposed on the magnetic filter body, a drive rod disposed on the output end of the push rod motor, the drive rod being inserted into and slidably connected to the magnetic filter body, and the other end of the drive rod being disposed on the closed cylinder.

[0010] In some embodiments, the magnetic filter body is symmetrically provided with insert rods, and the insert rods are slidably inserted into the closed cylinder and extend into the closed cylinder. The insert rods are symmetrically provided with through holes, and the closed cylinder is symmetrically provided with insertion holes, and the insertion holes correspond to the insert rods.

[0011] In some embodiments, the drain pipe includes a first discharge pipe and a second discharge pipe connected to each other, and the closed cylinder is symmetrically provided with docking holes corresponding to the inlet pipe and the drain pipe.

[0012] In some embodiments, the closed cylinder is provided with a guide cylinder, the guide cylinder is configured with a conical structure, and a magnetic rod penetrates the guide cylinder and extends to the bottom of the guide cylinder, and the guide cylinder is provided with uniformly distributed liquid holes.

[0013] In some embodiments, a connecting plate is provided on one side of the guide tube.

[0014] This utility model has at least the following beneficial effects:

[0015] When the electrolyte flow rate is low, the drive unit raises the sealed cylinder, creating a water storage space inside. Due to the small space, the electrolyte level rises, increasing the contact area with the magnetic rod, thus fully purifying the electrolyte, improving filtration efficiency, and increasing impurity adsorption. When the electrolyte flow rate is high, the drive unit lowers the sealed cylinder, exposing the insertion rod through-hole. The electrolyte flows down through this hole, simultaneously releasing space in the magnetic filter body to ensure smooth electrolyte passage, accommodate a large amount of electrolyte, avoid clogging, and maintain filtration continuity and stability.

[0022] 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. Example

[0023] Please see Figures 1-5 This utility model provides a technical solution:

[0024] An installation structure for a magnetic filter for electrolyte in a new energy vehicle battery includes a magnetic filter body 1, a handle 4 on the magnetic filter body 1, and evenly distributed magnetic rods 15 on the handle 4. An inlet pipe 2 and a drain pipe 3 are respectively connected to the magnetic filter body 1. The handle 4 facilitates the handling and installation of the magnetic filter body 1. The magnetic rods 15 on the handle 4 have strong magnetism. When the electrolyte flows inside the magnetic filter body 1, the magnetic rods 15 can adsorb magnetic impurities, thereby achieving filtration of the electrolyte. The magnetic filter body 1 provides an installation base and filtration space for other components. The inlet pipe 2 and the drain pipe 3 are respectively connected to its exterior. The inlet pipe 2 is used to introduce the electrolyte to be filtered into the magnetic filter body 1, while the drain pipe 3 is responsible for discharging the filtered electrolyte.

[0025] It also includes a closed cylinder 8, which is slidably connected inside the magnetic filter body 1. The magnetic rod 15 passes through the closed cylinder 8 and extends to the bottom of the closed cylinder 8. The top of the closed cylinder 8 has an opening, forming an open structure. The magnetic filter body 1 has symmetrically arranged insertion rods 11, which are slidably inserted into the closed cylinder 8 and extend into the closed cylinder 8. The insertion rods 11 have symmetrically arranged through holes 12, and the closed cylinder 8 has symmetrically arranged insertion holes 14, which correspond to the insertion rods 11. The drain pipe 3 includes a first discharge pipe 9 and a second discharge pipe 10 connected together. The closed cylinder 8 has symmetrically arranged docking holes 16 corresponding to the inlet pipe 2 and the drain pipe 3. The opening at the top of the closed cylinder 8 forms an open structure, which facilitates the smooth entry of electrolyte into the cylinder for filtration. The docking holes 16 ensure that the electrolyte in the inlet pipe 2 can flow into the closed cylinder 8 accurately. At the same time, the filtered electrolyte can also smoothly enter the drain pipe 3 through the docking holes 16 and be discharged, ensuring the smooth operation of the entire filtration process.

[0026] A drive unit 5 is provided on the magnetic filter body 1, and the drive unit 5 is used to drive the closed cylinder 8 to move up and down inside the magnetic filter body 1. The drive unit 5 includes a push rod motor 6 provided on the magnetic filter body 1, and a drive rod 7 is provided on the output end of the push rod motor 6. The drive rod 7 is inserted into the magnetic filter body 1 and slidably connected, and the other end of the drive rod 7 is provided on the closed cylinder 8. The main function of the drive unit 5 provided on the magnetic filter body 1 is to drive the closed cylinder 8 to move up and down inside the magnetic filter body 1. By controlling the position of the closed cylinder 8, the space it occupies inside the magnetic filter body 1 can be changed, thereby realizing flexible adjustment of the filtration space.

[0027] In use, the electrolyte to be filtered flows into the magnetic filter body 1 through the inlet pipe 2 and enters the interior of the sealed cylinder 8 through the docking hole 16 on the sealed cylinder 8. Inside the sealed cylinder 8, the electrolyte comes into full contact with the magnetic rod 15, and the magnetic impurities are adsorbed by the magnetic rod 15. At the same time, the drive unit 5 can drive the sealed cylinder 8 to move up and down according to the actual situation to adjust the filtration effect. The filtered electrolyte enters the drain pipe 3 through the docking hole 16 and is discharged through the first discharge pipe 9 and the second discharge pipe 10.

[0028] When the electrolyte flow rate is low, the drive unit 5 drives the closed cylinder 8 to rise to the upper position. At this time, the internal space of the closed cylinder 8 becomes a water storage space, replacing the space inside the magnetic filter body 1. Due to the relatively small space of the closed cylinder 8, the water level of the electrolyte rises, thereby increasing the contact area between the electrolyte and the magnetic rod 15. More magnetic impurities have the opportunity to contact the magnetic rod 15 and be adsorbed, effectively improving the filtration efficiency and ensuring that the electrolyte can be fully purified even under low flow conditions. When the electrolyte flow rate is high, the drive unit 5 drives the closed cylinder 8 to descend. As the closed cylinder 8 descends, the through hole 12 on the insertion rod 11 is exposed, and the electrolyte can flow into the lower part of the closed cylinder 8 through the through hole 12. At the same time, after the closed cylinder 8 descends, it completely releases the space inside the magnetic filter body 1, giving it a larger volume to accommodate a large amount of electrolyte. In this way, under high flow conditions, the electrolyte can pass smoothly through the magnetic filter body 1, avoiding the clogging problem caused by excessive flow and ensuring the continuity and stability of the filtration process. Example

[0029] Please see Figures 1-5 This utility model provides a technical solution:

[0030] A guide tube 13 is provided on the closed cylinder 8. The guide tube 13 is a conical structure, and the magnetic rod 15 passes through the guide tube 13 and extends to the bottom of the guide tube 13. The guide tube 13 has evenly distributed liquid holes 17, and a connecting plate 18 is provided on one side of the guide tube 13.

[0031] Unlike Example 1, the conical design of the guide tube 13 guides the electrolyte entering the closed tube 8. The magnetic rod 15 penetrates the guide tube 13 and extends below it, allowing the electrolyte to fully contact the magnetic rod 15 as it passes through the guide tube 13. After the electrolyte enters the guide tube 13, some of it flows out through the liquid holes 17. The uniform distribution of the liquid holes 17 ensures that the electrolyte is evenly dispersed within the closed tube 8, further increasing the contact area and contact opportunities between the electrolyte and the magnetic rod 15. When the electrolyte flow rate is low, the liquid holes 17 allow the electrolyte to flow more fully around the magnetic rod 15, improving the adsorption efficiency of magnetic impurities. When the flow rate is high, the liquid holes 17 also play a certain role in diverting the flow, preventing the electrolyte from becoming too concentrated and ensuring the stability of the filtration effect.
