Description

Technical Field

[0001] The utility model belongs to the technical field of battery production and related equipment, in particular to a ternary positive electrode material precursor washing device. Background Art

[0002] With the development of society and technology, equipment in various fields has been greatly improved. The precursor products of ternary composite positive electrode materials are produced with nickel salt, cobalt salt and manganese salt as raw materials, and the ternary precursors can be used to manufacture electric vehicle batteries. The ternary positive electrode material precursors require washing equipment for processing during production to improve subsequent production results.

[0003] After searching, the publication number CN213253382U, application date 2020.06.18 discloses a ternary positive electrode material precursor washing device, including a washing drum, a slot, an adsorption mechanism, a cover, a motor, a feed port, a stirring mechanism, a discharge valve, and a base. A slot is provided on the inner peripheral surface of the washing drum, and an adsorption mechanism is embedded in the inside of the slot; a cover is provided on the upper end surface of the washing drum, and a motor is provided at the upper end of the cover, and a feed port is provided in the middle part of the upper end of the cover; a discharge valve is provided at the inner bottom end of the washing drum, and a base is installed at the outer bottom end of the washing drum by bolts; the stirring mechanism includes a stirring feed pipe, a stirring tennis ball, and a stirring rod, and a stirring tennis ball is installed at the bottom end of the stirring feed pipe, and a stirring rod is provided on the outer surface of the stirring feed pipe.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The above-mentioned ternary cathode material precursor washing device improves the material washing effect through a stirring mechanism during use. However, this method will generate a vortex during the stirring process, causing the material and dirt to sink to the bottom, affecting the normal washing operation of the material;

[0006] 2. The aforementioned ternary cathode material precursor washing device uses an adsorption mechanism to absorb impurities during the washing process. However, this method relies solely on the centrifugal force generated during the stirring process to absorb impurities, which affects the suction effect and efficiency. To address this issue, we provide a ternary cathode material precursor washing device to address the aforementioned issues. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment 1

[0034] See also Figures 1 to 3 The utility model is a ternary positive electrode material precursor washing device, comprising a washing box 1 and mounting grooves 103 arranged at the center positions on both sides thereof, a tumbling assembly 2 is arranged directly behind the washing box 1; the tumbling assembly 2 includes a filter box 201, a front end face of which is provided with an air outlet pipe 2011 on one side, and the other end of the air outlet pipe 2011 is connected to the blower 202 through a pipe joint.

[0035] Specifically, a cover 101 is installed on the top of the washing box 1, and a feed pipe 1011 is provided on one side of the upper surface of the cover 101. A hollow arc-shaped cylinder 102 is installed at the center position of the interior of the washing box 1. A discharge pipe 104 is provided at the center position of the bottom of the washing box 1. The air outlet end of the blower 202 is connected to the air supply pipe 2021 through a pipe joint. The other end of the air supply pipe 2021 is connected to the air supply pipe 2022 and the annular nozzle 203 through a three-way joint. The other end of the air supply pipe 2022 is connected to the inflation pipe 2023 through a pipe joint. The other end of the inflation pipe 2023 is connected to the air supply pipe 2021 through a three-way joint. The end is arranged at the top of the rear end face of the washing box 1, and nozzles 2031 are installed at even intervals in the circumferential direction on the top of the annular nozzle 203.

The other end of the return air pipe 2012 is connected to the external pipe 2013 and the circulation pipe 2014 through a three-way joint. The other end of the circulation pipe 2014 is connected to the exhaust pipe 2015 through a pipe joint. The other end of the exhaust pipe 2015 is arranged at the top of the outer wall of one side of the washing box 1.

[0036] Furthermore, the pipe joint and the three-way joint both serve as pipeline connections. The hollow arc-shaped cylinder 102 allows the air introduced from the top to flow along the center. The annular nozzle 203 is located on the outside of the bottom end of the washing box 1 and is provided with multiple nozzles 2031, which serve to introduce air, causing the liquid inside the washing box 1 to continuously roll. The filter screen 204 can filter the inhaled and returned air.

[0037] The operation process of this embodiment is as follows: the precursor of the ternary positive electrode material and the water for washing are added to the inside of the washing box 1 through the feeding pipe 1011, and then the blower 202 is started. The blower 202 is operated to extract the air in the filter box 201 through the air outlet pipe 2011, and then the air is respectively sent into the top of the washing box 1 and the inside of the annular nozzle 203 through the air supply pipe 2021, the air supply pipe 2022 and the inflation pipe 2023.

[0040] Specifically, air holes 3011 are evenly spaced apart at the center of the outer wall of the mounting plate 301 , and a filtering mechanism 303 is provided on the outer wall of the mounting plate 301 .

[0041] Furthermore, the sealing gasket 302 serves to seal the inner wall of the mounting plate 301, and the exhaust fan 401 can extract the air inside the washing box 1 to accelerate the adsorption effect and efficiency of impurities, dirt, etc. The filtering mechanism 303 is an existing technology, so it will not be described in detail here. Only air can pass through the air hole 3011.

[0042] The operating process of this embodiment is: during the washing process of the precursor of the ternary positive electrode material, the impurities, dirt, etc. generated will be filtered into the interior through the filtering mechanism 303. At this time, the exhaust fan 401 is started, and the exhaust fan 401 operates to extract the air inside the washing box 1 through the exhaust pipe 4011 and the adsorption pipe 402, and under the action of multiple air holes 3011 on the surface of the mounting plate 301, the effect on impurities and dirt in the adsorption process can be increased, which can improve the pollution absorption effect.
