Description

Technical Field

[0001] This utility model relates to the field of nickel carbonate production technology, specifically to a pipeline for conveying reaction materials of nickel carbonate. Background Technology

[0002] Nickel carbonate is an important inorganic compound, usually appearing as a pale green powder, and is widely used in electroplating, catalyst manufacturing, and the production of lithium-ion battery cathode materials. In industrial production, nickel carbonate is typically produced by reacting nickel salt solutions with carbonates to form a precipitate, which is then filtered, washed, and dried. During this process, material transport pipelines are widely used to transport reaction raw materials (such as nickel salt solutions, carbonate solutions, and intermediate slurries) to reaction equipment or other process stages.

[0003] However, the material transport pipelines involved in nickel carbonate production are subject to long-term erosion and wear from a mixture of corrosive liquids and solid particles. The slurry transported within the pipelines is highly corrosive and abrasive, especially under the influence of liquid-solid two-phase flow. Traditional metal or ordinary plastic pipes exhibit poor durability and are prone to internal wall wear, corrosion, and cracking. After prolonged use, the pipelines become severely worn and must be replaced, which increases maintenance costs.

[0004] Furthermore, mixtures of liquids and solid particles are prone to accumulation in pipelines during transport due to uneven fluid distribution, leading to blockages. Blockages not only affect the normal transport of materials but can also cause equipment malfunctions, reduce production efficiency, and increase maintenance costs.

[0005] In summary, existing material conveying pipelines in nickel carbonate production suffer from insufficient wear resistance and corrosion resistance, high maintenance costs, and susceptibility to blockage. Therefore, we propose a reaction material conveying pipeline for nickel carbonate. Utility Model Content

[0006] The purpose of this invention is to provide a pipeline for conveying reactants of nickel carbonate, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The reaction material conveying pipeline for nickel carbonate includes a feed conveying assembly and an additional conveying assembly. The additional conveying assembly is used to extend the pipeline length to adapt to different production scenarios. The number of additional conveying assemblies can be increased or decreased according to the conveying requirements, or the additional conveying assemblies can be omitted.

[0009] The feeding and conveying assembly includes a first conveying pipe, which serves as a basic conveying section and provides an initial flow channel for the nickel carbonate reaction raw materials. A feed pipe is provided at the top of the outer wall of the first conveying pipe and near the left end. The feed pipe is used to connect to external feeding equipment to input reaction raw materials such as nickel salt solution and carbonate solution into the pipeline.

[0010] The first conveying pipe is equipped with a detachable first wear-resistant inner liner. The first wear-resistant inner liner is made of ceramic or polymer composite material. The polymer composite material is ultra-high molecular weight polyethylene or polytetrafluoroethylene, and at least one of carbon fiber and ceramic particles is added as a reinforcing phase to improve wear resistance and corrosion resistance. It directly contacts the corrosive slurry and resists chemical corrosion and solid particle erosion in nickel carbonate production.

[0011] The outer wall of the first wear-resistant inner liner tube is provided with a feed port that communicates with the feed pipe. A rubber ring is provided on the outer wall of the first wear-resistant inner liner tube at the edge of the feed port. The rubber ring is tightly fitted with the inner wall of the first conveying pipe. The rubber ring seals the connection gap between the feed port and the feed pipe to prevent nickel carbonate slurry from seeping into the interlayer between the first conveying pipe and the first wear-resistant inner liner tube, and to ensure that all the material output from the feed pipe enters the first wear-resistant inner liner tube.

[0012] The left end of the first conveying pipe is provided with an anti-blocking flow guiding component. The anti-blocking flow guiding component is used to force the flow of nickel carbonate slurry and prevent solid particles from accumulating in the pipe. The anti-blocking flow guiding component includes a cover plate, which closes the left end of the first conveying pipe and supports the installation of the motor. The left side of the cover plate is provided with a motor, which is connected to an external power supply and controller. The output shaft of the motor is connected to an auger through a mechanical seal. The outer wall of the auger is in contact with the inner wall of the first wear-resistant inner liner. The motor drives the auger to rotate, forcing the material to move in the conveying pipe and avoiding the situation of material blocking the conveying pipe.

[0013] The added conveying assembly includes a second conveying pipe connected to the first conveying pipe. The second conveying pipe serves as an extension section to expand the pipeline conveying distance to meet the layout requirements of different reaction equipment. The second conveying pipe is equipped with a detachable second wear-resistant inner liner. The second wear-resistant inner liner has the same function as the first wear-resistant inner liner, protecting the inner wall of the second conveying pipe from wear and corrosion by nickel carbonate slurry.

[0014] Preferably, a first left docking flange is provided at the left end of the outer wall of the first conveying pipe. The first left docking flange is locked to the cover plate by bolts and nuts. The first left docking flange is connected by bolts to realize the disassembly and assembly of the anti-blocking guide assembly.

[0015] Preferably, a first rubber gasket is provided between the first left mating flange and the cover plate. The first rubber gasket enhances the sealing of the flange connection and prevents leakage of nickel carbonate slurry.

[0016] Preferably, the outer wall of the first wear-resistant inner liner tube is provided with four first positioning strips arranged in a circular array. The first positioning strips cooperate with the first positioning grooves to ensure accurate alignment of the first wear-resistant inner liner tube during installation and prevent rotational displacement. The left end of the first positioning strip is located on the same plane as the left side of the first wear-resistant inner liner tube, and the length of the first positioning strip is half the length of the first wear-resistant inner liner tube.

[0017] Preferably, the inner wall of the first conveying pipe is provided with a first positioning groove that is adapted to the first positioning strip. The first positioning groove restricts the circumferential displacement of the first wear-resistant inner liner and improves the stability of the inner liner.

[0018] Preferably, the right end of the outer wall of the first conveying pipe is provided with a first right docking flange, which is used to connect additional conveying components or reaction equipment. The left end of the outer wall of the second conveying pipe is provided with a second left docking flange. The first right docking flange is locked to the second left docking flange by bolts and nuts. The second left docking flange and the first right docking flange cooperate to realize the modular expansion of the pipeline.

[0019] Preferably, a second rubber gasket is provided between the first right mating flange and the second left mating flange. The second rubber gasket seals the flange connection to prevent nickel carbonate slurry from leaking in the pipeline extension section.

[0020] Preferably, the outer wall of the second wear-resistant inner liner tube is provided with four second positioning strips arranged in a circular array. The second positioning strips cooperate with the second positioning grooves to ensure the installation accuracy of the second wear-resistant inner liner tube in the second conveying pipe. The left end of the second positioning strip is on the same plane as the left side of the second wear-resistant inner liner tube, and the length of the second positioning strip is half the length of the second wear-resistant inner liner tube.

[0021] Preferably, the inner wall of the second conveying pipe is provided with a second positioning groove that is adapted to the second positioning strip. The second positioning groove fixes the position of the second wear-resistant inner liner and prevents it from shifting due to slurry impact.

[0022] Preferably, a second right docking flange is provided at the right end of the outer wall of the second conveying pipe. The second right docking flange is used to connect reaction equipment or other additional conveying components to form an expandable pipeline system.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. This nickel carbonate reaction material conveying pipeline, by adopting a detachable wear-resistant inner liner, directly contacts the corrosive media and solid particles in the nickel carbonate slurry, effectively resisting chemical corrosion and mechanical wear, significantly extending the service life of the pipeline, and reducing the problem of frequent replacement due to damage to the inner wall of the conveying pipeline.

[0025] 2. The nickel carbonate reaction material conveying pipeline is equipped with an anti-clogging and flow guiding component at the pipeline inlet. The auger rotation forces the slurry to flow, preventing the nickel carbonate slurry from accumulating in the pipeline due to the poor fluidity of the solid-liquid mixture. This solves the clogging problem and ensures production continuity and efficiency.

[0026] 3. The nickel carbonate reaction material conveying pipeline, through its flange connection structure and detachable wear-resistant inner liner design, supports partial replacement of worn parts without the need for overall pipeline replacement, significantly reducing maintenance costs; the modular expansion capability of the conveying components allows for flexible adjustment of the pipeline length according to production needs, adapting to different process layouts.

[0027] 4. The nickel carbonate reaction material conveying pipeline has a ring array of positioning strips on the outer wall of the wear-resistant inner liner, which cooperate with the positioning grooves on the inner wall of the conveying pipe to ensure accurate alignment of the inner liner during installation, prevent circumferential displacement caused by slurry impact or vibration, and improve the stability of pipeline operation.
