Description

Technical Field

[0001] This utility model relates to the field of battery-grade nickel sulfate solution technology, specifically a sampler for battery-grade nickel sulfate solution. Background Technology

[0002] Battery-grade nickel sulfate solution is a chemical substance used to prepare positive electrode materials for lithium-ion batteries. It is mainly used in the electroplating industry, pharmaceutical industry, and production of nickel-cadmium batteries. Its chemical composition includes nickel, sodium, magnesium, aluminum, silicon, potassium, calcium, and chromium. A sampler is typically used to extract battery-grade nickel sulfate solution. Existing samplers involve marking the sampling rope, fixing it to the sampling bucket, and slowly lowering it to the desired sampling point. Pulling the rope causes the bucket to sink due to inertia, and the lid's spring clip automatically opens. Air bubbles will overflow during sampling; once the bubbles disappear, the sample is full. The sample is then removed and poured out. This process requires experience; the pulling force must be just right. Otherwise, either too much force will prevent the lid from opening, or too much force will pull the entire sampling bucket out of the tank containing the battery-grade nickel sulfate solution, requiring the bucket to be placed back in the tank. This operation is overly cumbersome.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese patent application number: 202222567867.8, application date: September 27, 2022) discloses a battery-grade nickel sulfate solution sampler, comprising: a sampler cylinder assembly; and a sampler top cover assembly. The sampler top cover assembly includes a cover plate assembly disposed at the liquid inlet end of the top of the sampler cylinder assembly, and a ring assembly coaxially disposed at the bottom of the cover plate assembly and inserted into the liquid inlet end of the top of the sampler cylinder assembly. This invention uses an electromagnetic push rod to fix the sampler top cover to the sampler cylinder. When needed, the electromagnetic push rod is driven to retract into the interior of the sampler top cover by electromagnetic induction, contacting the locking structure between the sampler top cover and the sampler cylinder, causing the sampler top cover to detach from the sampler cylinder. This allows the battery-grade nickel sulfate solution to enter the interior of the sampler cylinder through the liquid inlet end for sampling. The operation is simple and convenient, facilitating accurate sampling.

[0004] Although existing technology can sample battery-grade nickel sulfate solutions, the sampler lacks a multi-stage filtration mechanism when collecting battery-grade nickel sulfate solutions, which means that impurities in the solution (such as suspended solids and tiny particles) cannot be effectively removed, affecting the purity of the collected solution. In addition, battery-grade nickel sulfate solutions are usually corrosive, but the sampler does not have a protective structure, which affects the sampler's service life and accuracy.

[0005] Therefore, we propose a sampler for battery-grade nickel sulfate solution that can effectively solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a sampler for battery-grade nickel sulfate solution, in order to solve the problems mentioned in the background art. Currently, when using samplers to collect battery-grade nickel sulfate solution, the lack of a multi-stage filtration mechanism results in impurities (such as suspended solids and tiny particles) in the solution not being effectively removed, affecting the purity of the collected solution. Furthermore, battery-grade nickel sulfate solution is usually corrosive, but the sampler does not have a protective structure, affecting the sampler's service life and accuracy.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sampler for battery-grade nickel sulfate solution, comprising a sampling shell, a sealing plug movably connected to the top of the sampling shell, an outlet pipe fixedly installed on the left side of the bottom of the sampling shell, a base fixedly connected to the bottom of the sampling shell, and a high-efficiency sampling pump body disposed inside the base; an inlet pipe fixedly installed on the left side of the sampling shell, a first flange fixedly connected to the left side of the inlet pipe, a second flange movably connected to the left side of the first flange, and five fastening bolts threaded internally on the second flange; a connecting pipe fixedly installed on the left side of the second flange, a filter assembly for multi-stage filtration disposed on the left side of the connecting pipe, a splicing pipe movably connected to the left side of the filter assembly, and a suction pipe fixedly installed on the left side of the splicing pipe.

[0008] As a preferred technical solution of this application, a handle is fixedly installed on the top of the sealing plug, and a plurality of sealing rings are fixedly connected to the outer wall of the sealing plug, and the sealing rings are made of rubber.

[0009] As a preferred technical solution of this application, the sampling shell includes an outer shell, and an inner shell is fixedly installed inside the outer shell. The inner shell is made of polytetrafluoroethylene (PTFE). Because the inner shell is made of PTFE, PTFE has excellent chemical stability and can resist the corrosion of battery-grade nickel sulfate solution, ensuring that the inner shell will not undergo chemical reaction during long-term contact with the solution, thereby ensuring that the service life of the sampling shell and the quality of the sampled solution are not affected.

[0010] As a preferred technical solution of this application, the filter assembly includes a filter cylinder, a first filter plate is movably connected inside the filter cylinder, a second filter plate is movably connected inside the filter cylinder and the second filter plate is located to the right of the first filter plate, a third filter plate is movably connected inside the filter cylinder and the third filter plate is located to the right of the second filter plate, a sealing cover is movably connected to the top of the filter cylinder, and positioning bolts are provided on the front and rear sides of the sealing cover.

[0011] As a preferred technical solution of this application, an installation pipe is fixedly installed on the left side of the filter cartridge, and the installation pipe has an internal thread. The installation pipe is movably connected to a splicing pipe.

[0012] As a preferred technical solution of this application, the installation pipe and the splicing pipe are connected by threads. The outer wall of the splicing pipe is provided with external threads. By manually rotating the liquid extraction pipe counterclockwise, the liquid extraction pipe drives the splicing pipe to rotate counterclockwise inside the installation pipe, so that the splicing pipe can be rotated out of the installation pipe.

[0013] As a preferred technical solution of this application, the filter cylinder is detachably connected to the first filter plate, the second filter plate, and the third filter plate. The filter cylinder is made of a coarse filter screen, the filter plate is made of a fine filter screen, and the third filter plate is made of a sponge core. The solution is initially filtered through the coarse filter screen of the first filter plate to remove larger impurity particles. The solution after initial filtration then passes through the second filter plate, which is made of a fine filter screen, to further filter the solution and remove smaller impurities.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This sampler for battery-grade nickel sulfate solution, by setting a first filter plate, a second filter plate, a third filter plate, and a high-efficiency sampling pump body, facilitates multi-stage filtration, sampling, and storage of battery-grade nickel sulfate solution. Furthermore, the inclusion of a splicing pipe, a sealing cover, and fastening bolts facilitates disassembly, maintenance, or replacement of the filter components and the extraction pipe, ensuring normal equipment operation. Additionally, the inclusion of a sealing plug and an inner shell enables the sampler to have a sealing cover and protective effect. Specific details are as follows:

[0015] 1. The system is equipped with a first filter plate, a second filter plate, a third filter plate, and a high-efficiency sampling pump. The battery-grade nickel sulfate solution is filtered through the first, second, and third filter plates in multiple stages. After passing through the connecting pipe and the inlet pipe, the solution finally enters the inner shell of the sampling shell for storage. This multi-stage filtration sampling and storage of the battery-grade nickel sulfate solution effectively removes impurities from the solution and ensures high purity of the collected solution.

[0016] Furthermore, a splicing pipe, a sealing cover, and fastening bolts are installed. The splicing pipe is driven by the liquid extraction pipe to rotate out of the installation pipe for disassembly, maintenance, or replacement. The sealing cover can be removed by the positioning bolts and moved upward to detach from the filter cartridge, making it easy to disassemble the first filter plate, the second filter plate, and the third filter plate in sequence for cleaning or replacement. With the fastening bolts, the filter cartridge can be removed from the first flange and the second flange, facilitating disassembly and maintenance.

[0017] 2. A sealing plug and inner shell are provided. The rubber sealing ring fits tightly against the inner wall of the inner shell, thus providing a good seal and preventing external air and impurities from entering the sampling shell. At the same time, it prevents leakage of battery-grade nickel sulfate solution inside the sampling shell. In addition, the inner shell is made of polytetrafluoroethylene, which can resist the corrosion of battery-grade nickel sulfate solution and ensure that no chemical reaction occurs in the inner shell during long-term contact with the solution. This ensures that the service life of the sampling shell and the quality of the sampled solution are not affected. Attached Figure Description

[0025] 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.

[0026] Please see Figures 1-6 The present invention provides the following technical solution:

[0027] Example 1: To address the problem that commercially available samplers lack a multi-stage filtration mechanism when collecting battery-grade nickel sulfate solutions, resulting in the inability to effectively remove impurities (such as suspended solids and microparticles) and affecting the purity of the collected solution, this example discloses a sampler for battery-grade nickel sulfate solutions, with the following technical details provided in the appendix. Figure 1 -Appendix Figure 2 and attached Figure 4 -Appendix Figure 6 The system includes a sampling shell 1, a sealing plug 2 movably connected to the top of the sampling shell 1, an outlet pipe 7 fixedly installed on the left side of the bottom of the sampling shell 1, a base 9 fixedly connected to the bottom of the sampling shell 1, and a high-efficiency sampling pump body 10 housed inside the base 9; an inlet pipe 11 fixedly installed on the left side of the sampling shell 1, a first flange 12 fixedly connected to the left side of the inlet pipe 11, a second flange 13 movably connected to the left side of the first flange 12, and five fastening bolts 14 threaded inside the second flange 13; a connecting pipe 15 fixedly installed on the left side of the second flange 13, a filter assembly for multi-stage filtration arranged on the left side of the connecting pipe 15, a splicing pipe 18 movably connected to the left side of the filter assembly, and a suction pipe 19 fixedly installed on the left side of the splicing pipe 18; the filter assembly includes a filter cylinder 16, a first filter plate 20 movably connected inside the filter cylinder 16, and the filter cylinder 16... The filter cylinder 16 is internally connected to a second filter plate 21, which is located to the right of the first filter plate 20. The filter cylinder 16 is internally connected to a third filter plate 22, which is located to the right of the second filter plate 21. A sealing cover 8 is movably connected to the top of the filter cylinder 16, and positioning bolts are provided on both the front and rear sides of the sealing cover 8. An installation tube 17 is fixedly installed on the left side of the filter cylinder 16, and the installation tube 17 has internal threads. A splicing tube 18 is movably connected inside the installation tube 17. The installation tube 17 and the splicing tube 18 are threaded together, and the outer wall of the splicing tube 18 has external threads. The filter cylinder 16 is detachably connected to the first filter plate 20, the second filter plate 21, and the third filter plate 22. The filter cylinder 16 is made of a coarse filter screen, the filter cylinder 16 is made of a fine filter screen, and the third filter plate 22 is made of a sponge core.

[0028] Staff placed the extraction tube 19 into the battery-grade nickel sulfate solution to be sampled, preparing for solution extraction. The staff then activated the high-efficiency sampling pump 10 via an external control panel, generating suction in the inner shell 6 to power the extraction. Under suction, the battery-grade nickel sulfate solution passed through the extraction tube 19 and the splicing tube 18 into the filter cartridge 16. In the filter cartridge 16, the solution first passed through the first filter plate 20, where a coarse filter removed larger impurities. The pre-filtered solution then passed through the second filter plate 21, made of a fine filter, further removing smaller impurities. The finely filtered solution then passed through the third filter plate 22, made of a sponge core, to remove any remaining minute impurities or suspended matter. After multi-stage filtration, the battery-grade nickel sulfate solution passed through the connecting tube 15 and the inlet tube 11, finally entering the inner shell 6 of the sampling shell 1 for storage, completing the sampling and storage process and achieving the desired battery-grade nickel sulfate solution. The liquid undergoes multi-stage filtration for sampling and storage, effectively removing impurities from the battery-grade nickel sulfate solution and ensuring high purity of the collected solution. After the sampler completes its operation, the operator manually rotates the extraction tube 19 counterclockwise, causing the splicing tube 18 to rotate counterclockwise within the installation tube 17. Since the external thread of the splicing tube 18 is threadedly connected to the internal thread of the installation tube 17, rotating the splicing tube 18 counterclockwise allows it to be removed from the installation tube 17, facilitating disassembly, repair, or replacement of the extraction tube 19. Next, the operator manually sequentially adjusts the positioning screws... Remove the sealing cover 8, unlock its fixation, and move it upwards to detach it from the filter cylinder 16. Then, disassemble the first filter plate 20, the second filter plate 21, and the third filter plate 22 in sequence for cleaning or replacement. Finally, manually remove the fastening bolts 14 to detach them from the first flange 12 and the second flange 13, thereby unlocking the fixation of the first flange 12 and the second flange 13. This allows for the disassembly and maintenance of the filter cylinder 16, enabling the disassembly, maintenance, or replacement of the filter assembly and the liquid extraction pipe 19, ensuring the normal operation of the equipment.

[0029] Example 2: This example discloses a sampler for battery-grade nickel sulfate solution, which facilitates the sealing and protection of the sampler. Please refer to the attached document. Figure 1 -Appendix Figure 4 A handle 3 is fixedly installed on the top of the sealing plug 2, and several sealing rings 4 are fixedly connected to the outer wall of the sealing plug 2. The sealing rings 4 are made of rubber. The sampling shell 1 includes an outer shell 5, and an inner shell 6 is fixedly installed inside the outer shell 5. The inner shell 6 is made of polytetrafluoroethylene material.

[0030] During operation, the sealing plug 2 is positioned within the inner shell 6 of the sampling shell 1. Several rubber sealing rings 4 on the outer wall of the sealing plug 2 are tightly fitted against the inner wall of the inner shell 6, providing a good seal and preventing external air and impurities from entering the sampling shell 1. This also prevents leakage of the battery-grade nickel sulfate solution inside the sampling shell 1. The inner shell 6 is made of polytetrafluoroethylene (PTFE), which has excellent chemical stability and resists corrosion from the battery-grade nickel sulfate solution. This ensures that the inner shell 6 will not undergo a chemical reaction during long-term contact with the solution, thus guaranteeing the service life of the sampling shell 1 and maintaining the quality of the sampled solution. When it is necessary to open the sampling shell 1, the operator firmly grasps the handle 3 and applies an upward pulling force, causing the sealing plug 2 to move upward. During this upward movement, the friction between the sealing rings 4 and the inner wall of the sampling shell 1 gradually decreases, eventually causing the sealing plug 2 to completely detach from the sampling shell 1, thereby opening the channel of the sampling shell 1 for cleaning. This achieves both sealing and protective effects for the sampler.
