Description

Technical Field

[0002] During the manufacturing process of sodium-ion batteries, lithium-ion batteries and other batteries, the positive electrode slurry is easily attached to the inner wall of the pipeline during transportation due to the high residual alkali content on the surface of the battery positive electrode material.

[0003] Usually, acid-base neutralization is used to prevent the slurry from sticking to the wall. For example, organic acid, inorganic weak acid, and carbonate are added during the homogenization process to neutralize the residual alkali on the positive electrode surface, improve the pH of the slurry, reduce the viscosity of the slurry, and reduce the adhesion of the slurry to the inner wall of the pipe.

[0004] However, the above method will affect the quality of the slurry during the acid-base neutralization process, and the slurry still sticks to the wall. Utility Model Content

The opening sizes of the first opening and the second opening of the first channel are different, so that when the slurry flows in the first channel, the slurry flow rate changes, the slurry is mixed evenly, thereby reducing the viscosity of the slurry and further reducing the adhesion of the slurry on the inner wall of the pipeline.

[0030] In the slurry transmission pipeline and batching system provided in the present application, there is no need to use the acid-base neutralization method to prevent the slurry from sticking to the wall, which avoids the generation of moisture during the acid-base neutralization process, thereby not affecting the slurry quality and reducing the adhesion of the slurry to the inner wall of the pipeline.

[0045] In the related art, when the adhesion of slurry to the inner wall of the pipe is reduced by acid-base neutralization, the quality of the slurry will be affected. The reason for this problem is that moisture will be generated after acid-base neutralization, and the moisture will mix in the slurry, reducing the quality of the slurry.

[0046] In view of the above technical problems, the slurry transmission pipeline and batching system provided in the embodiment of the present application change the flow rate of the slurry and mix the slurry evenly by means of the first baffle plate provided in the pipeline and the first channel provided between the first baffle plate and the inner wall of the pipeline. The slurry is also locally turbulent at the edge of the first baffle plate, which accelerates the flow of the slurry and reduces the viscosity of the slurry. No acid-base neutralization is required, thereby avoiding the reduction of the slurry quality and reducing the adhesion of the slurry to the inner wall of the pipeline.

[0047] In order to make the above-mentioned purposes, features and advantages of the embodiments of the utility model more obvious and easy to understand, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of this application.

[0048] The slurry transfer pipeline is used to transfer slurry, for example, it can be used for slurry transfer between the homogenization tank and the homogenization side buffer tank, slurry transfer between the homogenization tank and the coating side buffer tank, slurry transfer between the homogenization side buffer tank and the coating side buffer tank, or slurry transfer between the coating side buffer tank and the coating side storage tank.

[0049] like Figure 1 As shown, the slurry transmission pipeline includes a pipeline 100 and at least one set of primary flow blocking components 200. The pipeline 100 is a carrier in the slurry transmission process, and the pipeline 100 has a feed end 110 and a discharge end 120. The slurry flows into the pipeline 100 from the feed end 110 and flows out from the discharge end 120 of the pipeline 100. The shape of the pipeline 100 can be a hollow cylinder or a shape similar to a hollow cylinder.

[0050] like Figure 1 and Figure 2 As shown, the primary baffle assembly 200 is arranged in the pipeline 100 to adjust the flow direction of the slurry. The number of the primary baffle assembly 200 is at least one group, for example, one group, two groups, three groups or more. Figure 2 and Figure 3 As shown, each primary baffle assembly 200 may be arranged at intervals along the axis of the pipeline 100 .

[0051] like Figure 1 and Figure 2 As shown, each group of primary baffle assemblies 200 includes at least one first baffle plate 210, and the number of the first baffle plates 210 may be one or two. Figure 2 As shown, the first baffle 210 is tiltedly arranged in the pipe 100, and the first baffle 210 has two oppositely arranged first and second fitting surfaces, the first and second fitting surfaces are fitted on the inner wall of the pipe 100, and the first and second fitting surfaces match the shape of the inner wall of the pipe 100. The first baffle 210 can be welded to the inner wall of the pipe 100 through the first and second fitting surfaces. When the slurry flows through the first baffle 210, the slurry forms local turbulence at the edge of the first baffle 210, and the shear force in the local turbulence shears the slurry, reduces the viscosity of the slurry, and thus reduces the adhesion of the slurry to the inner wall of the pipe 100.

[0052] like Figure 2 As shown, there is a first channel 220 between the first baffle 210 and the inner wall of the pipe 100. When the slurry flows through the first channel 220, the slurry is restricted by the first baffle 210 and cannot pass through the first baffle 210, so that the slurry flow rate on the inner wall side of the pipe is accelerated, reducing the adhesion of the slurry on the inner wall side of the pipe 100.

[0053] like Figure 2As shown, the first channel 220 has a first opening 221 and a second opening 222, one of which is an inlet for the slurry and the other is an outlet for the slurry. For example, the first opening 221 can be an inlet for the slurry and the second opening 222 can be an outlet for the slurry.

[0054] The first opening 221 and the second opening 222 have different opening sizes. For example, the first opening 221 is larger than the second opening 222, so the flow path of the slurry becomes narrower, the flow rate of the slurry increases, and the adhesion of the slurry to the inner wall of the pipe 100 is reduced. Alternatively, the first opening 221 is smaller than the second opening 222, and the flow rate of the slurry slows down. However, when the slurry enters the inlet of the first channel 220, the flow path becomes wider and the flow rate increases, so that the flow rate of the slurry first increases and then slows down, thereby playing a homogenizing role and reducing the viscosity of the slurry.

[0055] The slurry transmission pipeline provided by the present application changes the flow rate of the slurry and mixes the slurry evenly by arranging the first baffle 210 in the pipeline 100 and the first channel 220 between the first baffle and the inner wall of the pipeline. In addition, the slurry forms local turbulence at the edge of the first baffle 210, speeding up the flow of the slurry, thereby reducing the viscosity of the slurry, eliminating the need for acid-base neutralization, thereby avoiding reducing the quality of the slurry and reducing the adhesion of the slurry to the inner wall of the pipeline.

[0056] In some embodiments, Figure 2 As shown, along the flow direction from the first opening 221 to the second opening 222, the first opening 221 is larger than the second opening 222, and the slurry flows from the first opening 221 to the second opening 222. Since the opening at the inlet end of the slurry is larger than the opening at the outlet end of the slurry, the flow path of the slurry becomes narrower, thereby accelerating the flow rate of the slurry and further reducing the adhesion of the slurry to the inner wall of the pipe 100.

[0057] In some embodiments, Figure 2 As shown, the first baffle plate 210 is tilted in the pipeline 100, and a first angle is formed between the first baffle plate 210 and the center line of the pipeline 100, and the first angle is greater than 0 degrees and less than or equal to 45 degrees. Such a setting can reduce the impact of the slurry on the first baffle plate 210, prevent the slurry from damaging the first baffle plate 210, and avoid impurities falling off the surface of the first baffle plate 210 and contaminating the slurry.

[0058] In some embodiments, Figure 1 and Figure 2 As shown, the primary baffle assembly 200 includes two first baffle plates 210. For example, the two first baffle plates 210 are Figure 1 and Figure 2The first baffle plate 210a and the first baffle plate 210b are arranged opposite to each other in the pipeline 100, and a second channel 230 is provided between the first baffle plate 210a and the first baffle plate 210b. Since the inlet and outlet of the first channel 220 between the first baffle plate 210 and the side wall of the pipeline 100 are different in size, the inlet and outlet of the second channel 230 are also different in size. As a result, part of the slurry flows in the second channel 230 and changes the flow rate, thereby reducing the slurry from sticking to the wall.

[0059] In some embodiments, the two first baffles 210 are symmetrically arranged relative to the center line of the pipeline 100, such as Figure 2 As shown, the first baffle 210a and the first baffle 210b are symmetrically arranged relative to the center line of the pipeline 100, so that the first baffle 210a and the first baffle 210b are easier to install on the inner wall of the pipeline 100 to avoid mutual interference between the two during installation.

[0060] In some embodiments, Figure 2 and Figure 3 As shown, the slurry transport pipeline also includes at least one set of secondary baffle assemblies 300 , the number of which can be one, two, three or more, and the secondary baffle assemblies 300 and the primary baffle assemblies 200 are alternately arranged along the axial direction of the pipeline 100 .

[0061] For example, the number of the first-stage baffle assembly 200 and the number of the second-stage baffle assembly 300 are both two. Figure 2 As shown, the first primary baffle assembly 200, the first secondary baffle assembly 300, the second primary baffle assembly 200 and the second secondary baffle assembly are sequentially arranged in the axial direction of the pipeline 100. In addition, the first secondary baffle assembly 300, the first primary baffle assembly 200, the second secondary baffle assembly 300 and the second primary baffle assembly 200 may also be sequentially arranged in the axial direction of the pipeline 100. In this arrangement, the slurry flows alternately through the primary baffle assembly 200 and the secondary baffle assembly 300.

[0062] like Figure 3 As shown, the secondary baffle assembly 300 includes at least one second baffle plate 310, a third channel 320 is provided between the second baffle plate 310 and the inner wall of the pipe 100, and the third channel 320 has a third opening 321 and a fourth opening 322. Figure 2 and Figure 3In the flow direction from the first opening 221 to the fourth opening 322, the third opening 321 is larger than the fourth opening 322, so that the slurry can flow from the first channel 220 into the third channel 320, and the inflow end of the third channel is larger than the outflow end, so that the flow rate and direction of the slurry are constantly changed, and the slurry is mixed, thereby reducing the adhesion of the slurry on the inner wall of the pipeline 100.

[0063] In some embodiments, Figure 1 and Figure 3 As shown, the secondary baffle assembly 300 includes two second baffle plates 310, referring to Figure 1 The second baffle plate 310 has two oppositely disposed third and fourth fitting surfaces, which fit on the inner wall of the pipe 100 and match the shape of the inner wall of the pipe 100. The second baffle plate 2310 can be welded to the inner wall of the pipe 100 via the third and fourth fitting surfaces. When the slurry flows through the second baffle plate 310, the slurry forms local turbulence at the edge of the second baffle plate 310. The shear force in the local turbulence shears the slurry, reduces the viscosity of the slurry, and thus reduces the adhesion of the slurry to the inner wall of the pipe 100.

[0064] For example, the two second baffles 310 are respectively second baffles 310a and 310b, the second baffles 310a and the second baffles 310b are arranged opposite to each other in the pipeline 100, and there is a fourth channel 330 between the second baffles 310a and the second baffles 310b, and the diameter of the input port of the fourth channel 330 can be larger than the diameter of the output port.

[0065] The second baffle plate 310a and the second baffle plate 310b are both arranged obliquely in the pipeline 100, and a second angle is formed between the second baffle plate 310a and the second baffle plate 310b and the center line of the pipeline. The second angle is greater than 0 degree and less than or equal to 45 degrees. Such an arrangement can reduce the impact of the slurry on the second baffle plate 310, prevent the slurry from damaging the second baffle plate 310, and avoid impurities falling off the surface of the second baffle plate 310 and contaminating the slurry.

[0066] In some embodiments, Figure 2 As shown, the first baffle plate 210a and the first baffle plate 210b are symmetrically arranged in the pipeline 100 relative to the first plane 240, and the first plane 240 is parallel to the center line of the pipeline 100. Figure 3 As shown, the second baffle plate 310a and the second baffle plate 310b are symmetrically arranged in the pipeline 100 relative to the second plane 340, and the second plane 340 is parallel to the center line of the pipeline 100. Figure 4As shown, a third angle is formed between the first plane 240 and the second plane 340, and the third angle is greater than 0 degrees and less than or equal to 90 degrees. The third angle is the minimum angle formed by the intersection of the first plane 240 and the second plane 340. For example, the third angle is 1 degree, 45 degrees, 60 degrees or 90 degrees.

[0067] From this setting, the flow direction of the slurry changes during the process of the slurry flowing from the primary baffle assembly 200 into the secondary baffle assembly 300, or during the process of the slurry flowing from the secondary baffle assembly 300 into the primary baffle assembly 200, thereby playing a role of homogenization, so that the materials in the slurry are mixed evenly, so as to reduce the viscosity of the slurry and further reduce the adhesion of the slurry to the inner wall of the pipeline 100.

[0068] In some embodiments, along the axial direction of the pipeline 100, the distance between adjacent primary baffle components 200 and secondary baffle components 300 is 50-300 mm, for example, 50 mm, 100 mm, 175 mm, 200 mm or 300 mm. Figure 2 There is a pair of baffles in the middle close to the feed end of the pipeline 100 , and the distance between the two is the distance between the top of the first baffle assembly 200 and the top of the second baffle assembly 300 .

[0069] The distance between the adjacent primary baffle assembly 200 and the secondary baffle assembly 300 is set to 50-300 mm. On the one hand, it is prevented that the adjacent primary baffle assembly 200 and the secondary baffle assembly 300 are too close to each other, resulting in the problem that the mixing time of the slurry is too short and the slurry is difficult to mix evenly during the process of the slurry flowing from the secondary baffle assembly 300 to the primary baffle assembly 200. On the other hand, it is prevented that the adjacent primary baffle assembly 200 and the secondary baffle assembly 300 are too far apart, resulting in the problem that the flow time of the slurry is too long during the process of the slurry flowing from the secondary baffle assembly 300 to the primary baffle assembly 200, and part of the slurry adheres to the inner wall of the pipe 100.

[0070] In some embodiments, the inner wall of the pipe 100, the surfaces of the primary baffle assembly 200 and the secondary baffle assembly 300 are coated with a wear-resistant layer. Specifically, the inner wall of the pipe 100, the surfaces of the primary baffle assembly 200 and the secondary baffle assembly 300 that are in contact with the slurry are coated with a wear-resistant layer. The material of the wear-resistant layer can be ceramic, but is not limited to ceramic. In addition, the surfaces of the primary baffle assembly 200 and the secondary baffle assembly 300 that are in contact with the slurry can be set as curved surfaces to facilitate the flow of the slurry, avoid right-angle turns when the slurry flows, speed up the flow of the slurry, and further reduce the adhesion of the slurry to the inner wall of the pipe 100.

[0071] In some embodiments, the thickness of the first baffle plate 210 and the second baffle plate 310 is 1-5 mm, such as 1 mm, 3 mm or 5 mm. This configuration can ensure the structural strength of the first baffle plate 210 and avoid occupying too much space in the pipeline 100.

[0072] In some embodiments, reference Figure 1 The first joint 130 and the second joint 140 are respectively provided at both ends of the pipeline 100. The first joint 130 and the second joint 140 can be quick-connect joints or can be ends of the pipeline 100. The first joint 130 is used to connect the feeding device. Specifically, the first joint 130 and the output end of the feeding device can be connected by a flange and sealed by a sealing ring or other sealing member. The feeding device is used to transport the slurry into the pipeline 100.

[0073] The second joint 140 is used to connect to the slurry receiving device. Specifically, the second joint 140 and the input end of the slurry receiving device can also be connected by a flange and sealed by a sealing ring or other sealing member. The slurry receiving device is used to receive the slurry output by the pipeline 100 .

[0074] The present application also provides a batching system, including a feeding device, a slurry receiving device, and a slurry transmission pipeline in any of the above embodiments. The feeding device is connected to the feeding end of the slurry transmission pipeline, for example, the feeding device is connected to the feeding end 110 of the slurry transmission pipeline through a flange, and is sealed by a sealing ring or other sealing member, so as to input slurry into the slurry transmission pipeline.

[0075] The slurry receiving device is connected to the discharge end 120 of the slurry transmission pipeline. For example, the slurry receiving device is connected to the discharge end of the slurry transmission pipeline through a flange and is sealed by a sealing ring or other sealing members to receive the slurry in the slurry transmission pipeline.

[0077] In some embodiments, the feeding device includes a homogenization tank, a buffer tank or a transmission pipe, so that the slurry in the homogenization tank, the buffer tank or the transmission pipe is output to the slurry receiving device through the slurry transmission pipeline. The buffer tank can be a homogenization side buffer tank or a coating side buffer tank. The transmission pipe can be a slurry transmission pipeline in any of the above embodiments, or other slurry transmission pipelines, so as to increase the transmission distance of the slurry by splicing.

[0078] In some embodiments, the slurry receiving device includes a buffer tank, a pump, a stirring tank or a transmission pipe, so as to receive the slurry output by the feeding device through the slurry transmission pipeline.
