The above-mentioned storage tank includes a tank body 11, a tank cover 12 and a feed piece 121. The tank body 11 is hollow inside to store materials. One end of the tank body 11 is open. The tank cover 12 is used to open or close the open end of the tank cover 12 to seal the tank body 11, prevent external impurities from entering the tank body 11, and improve the thermal insulation effect of the tank body 11. A plurality of fixed lock buckles are provided at intervals along the circumference of the open end of the tank body 11, and the fixed lock buckles are used to fix the tank cover 12 when the tank cover 12 closes the tank body 11. A feed piece 121 is provided on one side of the can cover 12 facing the can body 11. The feed piece 121 is a duckbill structure, and has a small end 1211 and a large end 1212 opposite to each other. The feed piece 121 is duckbill shaped, that is, along the direction from the small end 1211 to the large end 1212, its width increases, and preferably increases gradually, and its thickness decreases or remains unchanged; wherein, the width is Figure 3 As shown in the figure, the thickness dimension is the dimension perpendicular to the paper surface. The interior of the feed piece 121 is hollow. When in use, the slurry in the material source enters the feed piece 121 through the small end 1211 of the feed piece 121, and then is discharged into the tank body 11 through the large end 1212 of the feed piece 121.

[0038] In this embodiment, the duckbill-shaped feed piece 121 has a smooth front end and a wide mouth, which can moderate the speed at which the slurry enters the tank body 11 and reduce the kinetic energy of the turbulent body. Compared with the prior art, it can effectively reduce the probability of bubble formation and improve the coating quality.

[0039] The storage tank provided in the embodiment of the utility model is as follows Figure 1 and Figure 2As shown, the feed piece 121 has a relative upper surface and a lower surface, the upper surface is arranged toward the tank cover 12, and the lower surface is arranged toward the tank body 11; a first through hole 1215 connecting the interior of the feed piece 121 and the material source is opened on the side of the upper surface close to the small head end 1211, and a second through hole connecting the interior of the feed piece 121 and the interior of the tank body 11 is opened on the end surface of the large head end 1212.

[0040] In this embodiment, the feed piece 121 is formed by connecting the upper cover 1213 and the lower cover 1214. The upper cover 1213 and the lower cover 1214 are both grooved so that when the upper cover 1213 and the lower cover 1214 are connected, a feed piece 121 with a hollow interior is formed. The side of the upper cover 1213 away from the lower cover 1214 is the upper surface of the feed piece 121, and the side of the lower cover 1214 away from the upper cover 1213 is the lower surface of the feed piece 121. A first through hole 1215 is provided on the side of the upper surface close to the small end 1211, and the slurry enters the feed piece 121 through the first through hole 1215. A second through hole is provided on the end surface of the large end 1212, and the slurry entering the feed piece 121 is discharged through the second through hole and enters the tank body 11.

[0041] In this embodiment, by opening the first through hole 1215 on the upper surface, the speed of the slurry entering the tank body 11 can be further moderated, the kinetic energy of the turbulent body can be reduced, and the defoaming effect can be improved. Optionally, the first through hole 1215 can also be opened on the end surface of the small head end 1211, and the second through hole can also be opened at the junction of the upper surface or the lower surface and the large head end 1212.

[0042] Optionally, in the storage tank provided by the embodiment of the utility model, the area of ​​the second through hole is smaller than the area of ​​the first through hole 1215, thereby increasing the feed pressure of the slurry.

[0043] The storage tank provided in the embodiment of the utility model is as follows Figure 2 As shown, the large end 1212 of the feed piece 121 is arranged toward the inner wall of the tank body 11; the distance between the large end 1212 of the feed piece 121 and the inner wall of the tank body 11 is d, wherein 1mm≤d≤10mm.

[0044] In this embodiment, the big end 1212 of the feeding piece 121 is arranged toward the inner wall of the tank body 11, and the distance between the big end 1212 and the inner wall of the tank body 11 is greater than or equal to 1 mm and less than or equal to 10 mm, so that the material discharged from the big end 1212 can always hit the inner wall of the tank body 11, so that the material can flow downward along the inner wall of the tank body 11, thereby avoiding the material discharged from the big end 1212 of the feeding piece 121 directly mixing with the material in the tank body 11 to generate bubbles.

[0045] For example, in this embodiment, the distance between the large end 1212 of the feeding member 121 and the inner wall of the tank body 11 may be 5 mm.

[0046] It should be noted that the large end 1212 of the feed piece 121 is preferably tilted upward, and the above-mentioned d is the distance between the position of the large end 1212 of the feed piece 121 closest to the inner wall of the tank body 11 and the inner wall of the tank wall.

[0047] The storage tank provided in the embodiment of the utility model is as follows Figure 2 and Figure 4 As shown, the large end 1212 of the feed member 121 is tilted upward.

[0048] In this embodiment, the big end 1212 of the feed piece 121 is tilted upward, that is, when the axial direction of the tank body 11 is vertically arranged, the horizontal height of the big end 1212 of the feed piece 121 is higher than the horizontal height of the small end 1211 of the feed piece 121, so that the material discharged from the big end 1212 of the feed piece 121 can always hit the inner wall of the tank body 11, avoiding the material discharged from the big end 1212 of the feed piece 121 directly mixing with the material in the tank body 11 due to the high liquid level of the material in the tank body 11 to generate bubbles, thereby improving the defoaming effect.

[0049] The storage tank provided in the embodiment of the utility model is as follows Figure 1 and Figure 2 As shown, the tank wall of the tank body 11 is hollowed out to form a partition 111, and a medium inlet 113 and a medium outlet 114 are provided on the tank body 11; a partition 21 extending circumferentially along the tank body 11 is provided in the partition 111, and a plurality of partitions 21 are provided, and all the partitions 21 are spaced apart along the axial direction of the tank body 11; the partition 21 divides the partition 111 into a plurality of medium flow channels 211, and any two adjacent medium flow channels 211 are connected to each other; the medium inlet 113 and the medium outlet 114 are both connected to one of the medium flow channels 211.

[0050] In this embodiment, the tank body 11 has a tank wall, which is divided into an inner wall and an outer wall. The side of the tank wall facing the outside is the outer wall, and the other side is the inner wall. The tank wall of the tank body 11 is hollow, so that a partition 111 can be formed in the tank wall. A plurality of partitions 21 are arranged in the partition 111, and the partitions 21 are in a closed annular structure. The inner and outer sides of the partitions 21 are respectively connected to the partition 111. Each partition 21 extends along the circumferential direction of the tank body 11, and all the partitions 21 are arranged at intervals along the axial direction of the tank body 11. The partitions 21 separate the partition 111 into a plurality of medium flow channels 211. The tank body 11 is also provided with a medium inlet 113 and a medium outlet 114, both of which are connected to one of the medium flow channels 211, wherein the medium inlet 113 and the medium outlet 114 may be connected to the same medium flow channel 211, and since any two adjacent medium flow channels 211 are connected to each other, the medium can still fill each medium flow channel 211 after passing through the medium inlet 113 into the medium flow channel 211 connected to the medium inlet 113, and the medium inlet 113 and the medium outlet 114 may also be connected to two different medium flow channels 211 respectively, preferably, the medium inlet 113 is connected to the uppermost medium flow channel 211, and the medium outlet 114 is connected to the lowermost medium flow channel 211. It should be noted that the uppermost and lowermost medium flow channels 211 are both formed by the partition 21 and the partition layer 111, and the remaining medium flow channels 211 are located between two adjacent partitions 21.

[0051] Taking the storage tank used to cache the slurry for coating as an example, the medium inlet 113 and the medium outlet 114 are both connected to the heat medium source. When in use, the heat medium source passes the heat medium into the medium flow channel 211 through the medium inlet 113. After flowing in the medium flow channel 211, the heat medium will flow to the medium outlet 114, and the heat medium will then circulate back to the heat medium source from the medium outlet 114, thereby ensuring the temperature of the heat medium.

[0052] Optionally, in the present embodiment, the storage tank is a storage tank with a heating function when used to cache the slurry for coating. When the storage tank is used in other fields, the storage tank can also be a storage tank with a refrigeration function, and it is only necessary to pass a cold medium into the compartment 111.

[0053] The storage tank provided in this embodiment has a hollow tank wall of the tank body 11 and forms an interlayer 111. The storage tank can have a cooling or heating function by passing a medium into the interlayer 111. By arranging a partition 21 in the interlayer 111, the residence time of the medium in the interlayer 111 can be increased, thereby improving the cooling or heating effect. When the storage tank is used to store coating slurry, the temperature of the slurry can be increased. When the solid content of the slurry is constant, the increase in temperature can improve its fluidity, thereby improving the consistency of the coating surface density and improving the quality of the battery.

[0054] The storage tank provided in the embodiment of the utility model is as follows Figure 1 and Figure 2 As shown, the partition 21 is arranged tilted.

[0055] The above content mentioned that any two adjacent medium flow channels 211 are interconnected, and the partition 21 is tilted, which enables the medium to flow in the medium flow channel 211 formed by the partition 21, so that the medium can fill various positions of the partition 111, thereby improving the cooling or heating effect.

[0056] The storage tank provided in the embodiment of the utility model is as follows Figure 1 and Figure 2 As shown, the partition plate 21 is provided with a through hole or a notch.

[0057] In this embodiment, any two adjacent medium flow channels 211 can be interconnected by providing a through hole on the partition 21, or by providing a notch on both sides of the partition 21, wherein the notch can be formed by cutting off the partition 21.

[0059] In this embodiment, the storage tank further includes a stirring component and a dispersing component. The stirring component is used to stir the material in the tank body 11 to avoid precipitation, and the dispersing component is used to disperse and mix the material in the tank body 11, thereby improving the uniformity of the material.

[0060] Specifically, in the present embodiment, the stirring assembly includes a stirring shaft 32, a stirring motor 31 and a stirring paddle 33; the stirring paddle 33 is arranged on the stirring shaft 32, and the stirring motor 31 is arranged on the side of the tank cover 12 facing away from the tank body 11. One end of the stirring shaft 32 passes through the tank cover 12 and is transmission-connected to the stirring motor 31. The stirring shaft 32 is driven to rotate by the stirring motor 31, so that the stirring paddle 33 can stir the material in the tank body 11.

[0061] Furthermore, in the present embodiment, the dispersion assembly includes a dispersion motor 41, a dispersion shaft 42 and a dispersion disk 43; the dispersion disk 43 is arranged on the dispersion shaft 42, the dispersion motor 41 is arranged on the side of the tank cover 12 away from the tank body 11, one end of the dispersion shaft 42 passes through the tank cover 12 and is transmission-connected to the dispersion motor 41, and the dispersion shaft 42 is driven to rotate by the dispersion motor 41, so that the dispersion disk 43 can disperse the material in the tank body 11.

[0062] Preferably, in this embodiment, since the space required for the stirring paddle 33 to work is relatively large, and in order to enable the stirring paddle 33 to fully stir the materials in the tank body 11, the axis of the stirring shaft 32 coincides with the center of the tank cover 12, and the dispersion component is arranged next to the stirring component.

[0063] Furthermore, in this embodiment, in order to avoid interference between the stirring assembly and the dispersing assembly, the stirring paddle 33 is an anchor frame type stirring paddle 33 , and the length of the stirring shaft 32 is greater than the length of the dispersing shaft 42 .

The temperature detection sensor is used to detect the temperature of the material in the tank body 11. The operator can observe the temperature of the material in the tank body 11 according to the temperature detection sensor, so as to timely adjust the temperature of the medium in the interlayer 111 in real time, so that the material in the tank body 11 is always in an ideal state.

[0068] In this embodiment, the above content mentioned that the storage tank is used to buffer the slurry for coating. At this time, an oil temperature machine can be set to communicate with the medium inlet 113 and the medium outlet 114 to transport hot medium into the medium flow channel 211, thereby increasing the temperature of the slurry.
