Description

Technical Field

[0001] The utility model relates to the technical field of ton barrels, in particular to a ton barrel and battery sheet processing equipment. Background Art

[0002] Coolants generally include wetting agents, dispersants, defoamers and stabilizers, and they mainly play the role of dispersion, lubrication and cooling in the slicing of single crystal silicon rods. However, the coolant is prone to obvious stratification during storage, resulting in uneven composition of the coolant added to the cutting equipment during the actual cutting process, which affects the performance of the coolant to a certain extent, thereby affecting the efficiency of the cutting process and reducing the quality of the battery cell.

[0003] In the related art, in order to solve the problem of easy stratification during coolant storage, two methods are often used: adding a motor fan blade stirrer and reducing the storage volume. However, because the coolant barrel is square, the stirring effect of adding a motor fan blade stirrer is poor, and the motor fan blade stirrer is placed in the coolant barrel, which has the risk of being mixed with other impurities due to incomplete cleaning. Reducing the storage volume will restrict the production efficiency of single crystal silicon rod slicing and increase processing costs. Utility Model Content

[0027] Reference below Figure 1-Figure 5 The ton barrel 100 according to the first embodiment of the utility model is described. It should be noted that the ton barrel 100 is used to store coolant in the process of battery cell processing as an example for introduction in this application, but it is not limited to this.

[0028] like Figure 1-Figure 5 As shown, the ton barrel 100 according to the first embodiment of the utility model includes a barrel body 1, a barrel cover 2 and an agitator 3.

[0029] Specifically, the barrel body 1 is in a first direction (for example, Figure 1The barrel body 1 is open on one side in the second direction (for example, Figure 1 A liquid outlet 11 is formed on one side (in the left and right directions in the first direction), and the first direction is perpendicular to the second direction. The barrel cover 2 is arranged on the open side of the barrel body 1, and the barrel cover 2 and the barrel body 1 jointly define a accommodating chamber 12, and the accommodating chamber 12 is suitable for containing liquid (such as coolant). The agitator 3 is arranged in the accommodating chamber 12, and the agitator 3 includes a first rotating shaft 31 and a plurality of stirring blades 32. The first rotating shaft 31 is arranged along the first direction, and the first rotating shaft 31 is suitable for being connected to the motor. Each stirring blade 32 is connected to the first rotating shaft 31 and extends in a direction away from the first rotating shaft 31. In the description of the present utility model, the meaning of "plurality" is two or more.

[0030] For example, in Figure 1 and Figure 4 In the example, the liquid outlet 11 of the barrel body 1 is away from the open side, so that the coolant can be injected into the accommodating cavity 12 from the open side of the barrel body 1, and when the coolant needs to be taken, the coolant is discharged from the liquid outlet 11. The liquid outlet 11 can be set at a position away from the open side in the first direction, that is, the liquid outlet 11 is adjacent to the bottom of the barrel body 1, so as to facilitate the discharge of the coolant in the accommodating cavity 12. Optionally, a control valve 111 is provided at the liquid outlet 11 to control the on and off of the liquid outlet 11 and the amount of liquid discharged.

[0031] An agitator 3 is provided in the accommodating chamber 12 to stir and mix the liquid in the accommodating chamber 12 to avoid stratification of the coolant in the accommodating chamber 12, thereby avoiding uneven distribution of the coolant components during the actual cutting process, thereby ensuring the performance of the coolant and improving the efficiency of the battery cell cutting process and the quality of the cut battery cells.

[0032] Among them, a plurality of stirring blades 32 are spaced apart along the circumference of the first rotating shaft 31 to give full play to the stirring effect of the stirring blades 32. The edges of the plurality of stirring blades 32 away from the first rotating shaft 31 are connected to form a Reuleaux triangle. With such an arrangement, the rotation area of ​​the plurality of stirring blades 32 is square, so that the agitator 3 is suitable for the barrel body 1 with a square cross-section. Compared with the traditional stirring assembly, the agitator 3 is more applicable. The agitator 3 is suitable for the square barrel body 1, avoiding the replacement of the barrel body 1, and is conducive to improving the uniformity of the composition of the coolant in the barrel body 1, that is, improving the uniformity of the coolant added when cutting the battery cell, thereby improving the cutting efficiency and quality of the battery cell.

[0033] Optionally, refer to Figure 4 and Figure 5 A stirrer 3 may be provided at each corner of the cross section of the barrel body 1 to prevent the components in the coolant from being deposited at the corners of the barrel body 1 , so as to improve the uniformity of the coolant in the barrel body 1 .

[0034] In addition, the coolant often contains a large amount of silicon powder. The above-mentioned ton barrel 100 is conducive to solving the sedimentation and separation problem of silicon powder in the coolant during storage. By making the large-circulation recycling water system stable and maintaining a large capacity, the cleaning time of the barrel body 1 can be reduced, the time cost can be reduced, and the silicon powder can be evenly dispersed. The silicon powder can be taken to the filter press for filtration, thereby increasing the output of silicon cakes and increasing economic benefits.

[0035] According to the ton barrel 100 of the embodiment of the utility model, the edges of the multiple stirring blades 32 of the agitator 3 away from the first rotating shaft 31 are connected to form a Reuleaux triangle, thereby improving the applicability of the agitator 3 and making the agitator 3 suitable for use with the square barrel body 1, avoiding the replacement of the barrel body 1, and being beneficial to improving the uniformity of the composition of the coolant in the barrel body 1, that is, improving the uniformity of adding the coolant when cutting the battery cells, thereby improving the cutting efficiency and quality of the battery cells.

[0036] According to some embodiments of the present invention, referring to Figure 1 and Figure 4 , a plurality of stirring blades 32 are spaced apart along the axial direction of the first rotating shaft 31. For example, Figure 1 In the example, three stirring blades 32 are provided at axial intervals along the first rotating shaft 31 to stir the coolant at different heights in the barrel body 1, thereby improving the uniformity of the stirring of the coolant in the barrel body 1 by the stirrer 3, and at the same time facilitating stirring when the volume of the coolant in the barrel body 1 is small.

[0037] Further, refer to Figure 1 The two outermost stirring blades 32 of the plurality of stirring blades 32 in the axial direction of the first rotating shaft 31 are respectively the first stirring blade 321 and the second stirring blade 322, and the first stirring blade 321 is adjacent to the barrel cover 2. The first stirring blade 321 is adjacent to the barrel cover 2, and the second stirring blade 322 is adjacent to the bottom of the barrel body 1, so that the first stirring blade 321 drives the coolant adjacent to the barrel cover 2, and the second stirring blade 322 drives the coolant adjacent to the bottom of the barrel body 1, so as to achieve stirring and mixing of the coolant at different heights, thereby improving the mixing efficiency of the coolant.

[0038] Among them, refer to Figure 1 In the axial direction of the first rotating shaft 31, the minimum distance between the connection between the first stirring blade 321 and the first rotating shaft 31 and the end of the first rotating shaft 31 adjacent to the barrel cover 2 is H1, and in the axial direction of the first rotating shaft 31, the minimum distance between the connection between the second stirring blade 322 and the first rotating shaft 31 and the end of the first rotating shaft 31 away from the barrel cover 2 is H2, and H1 and H2 satisfy: H1>H2.

[0039] The cooling liquid is less difficult to stir at a position adjacent to the barrel cover 2; therefore, the minimum distance between the connection between the first stirring blade 321 and the first rotating shaft 31 and the end of the first rotating shaft 31 adjacent to the barrel cover 2 in the axial direction of the first rotating shaft 31 is larger, so as to fully utilize the first stirring blade 321 to stir the cooling liquid in the accommodating chamber 12.

[0040] At least some components in the coolant are easy to settle at the bottom of the barrel body 1. The minimum distance between the connection between the second stirring blade 322 and the first rotating shaft 31 and the end of the first rotating shaft 31 away from the barrel cover 2 in the axial direction of the first rotating shaft 31 is small, which is conducive to reducing the distance between the second stirring blade 322 and the bottom of the barrel body 1. Therefore, the second stirring blade 322 can directly act on the settled components without additional energy to lift the settled components. The second stirring blade 322 can effectively create a stronger vortex and improve the uniformity of the coolant in the accommodating chamber 12, so that the ton barrel 100 can effectively solve the problem of easy stratification of the coolant during storage and a large amount of residue at the bottom of the barrel body 1 without reducing the output, and improve the uniformity of adding coolant when cutting the battery cells, thereby improving the cutting quality and efficiency of the battery cells.

[0041] According to some embodiments of the present invention, referring to Figure 1 and Figure 4 , the thickness of each stirring blade 32 in the first direction gradually increases in the direction away from the first rotating shaft 31. With such a configuration, the structural strength of the stirring blade 32 in the direction away from the first rotating shaft 31 is improved to prevent the stirring blade 32 from being damaged or broken during the stirring process, thereby extending the service life of the stirring blade 32. At the same time, the action area of ​​each stirring blade 32 at a position away from the first rotating shaft 31 and the coolant is increased, so that during the rotation of the first rotating shaft 31, it is beneficial to improve the cutting and stirring effect of each stirring blade 32 on the position away from the first rotating shaft 31, so as to improve the mixing effect of the stirring blade 32 on the coolant.

[0042] Further, refer to Figure 1 and Figure 4 The surface of one side of each stirring blade 32 away from the first rotating shaft 31 extends obliquely toward the bottom wall of the barrel body 1. Thus, the angle at which the stirring blade 32 acts on the coolant is increased, so that the stirring blade 32 can act on the coolant during the rotation of the first rotating shaft 31, thereby ensuring the stirring effect on the coolant.

[0043] Furthermore, refer to Figure 1 and Figure 4, at least part of each stirring blade 32 in the first direction protrudes toward the barrel cover 2; and / or at least part of each stirring blade 32 in the first direction protrudes toward the bottom wall of the barrel body 1. That is, at least part of each stirring blade 32 only protrudes toward the barrel cover 2 in the first direction; or at least part of each stirring blade 32 only protrudes toward the bottom wall of the barrel body 1 in the first direction; or at least part of each stirring blade 32 in the first direction protrudes toward the barrel cover 2, and at least part of each stirring blade 32 protrudes toward the barrel cover 2. In this way, the extension area of ​​each stirring blade 32 is increased, thereby increasing the contact area between each stirring blade 32 and the coolant, which is beneficial to improving the stirring and mixing efficiency of the agitator 3 on the coolant.

[0044] According to some embodiments of the utility model, in the second direction, the side of the bottom wall of the barrel body 1 adjacent to the liquid outlet 11 is lower than the side of the bottom wall of the barrel body 1 away from the liquid outlet 11. As a result, the coolant in the accommodating cavity 12 can smoothly flow out from the liquid outlet 11, thereby facilitating the speed and volume of adding coolant when cutting the battery cell, thereby ensuring the efficiency of battery cell cutting. At the same time, the coolant remaining at the bottom of the barrel body 1 can be completely taken out to reduce waste.

[0045] In addition, refer to Figure 1 The bottom wall of the barrel body 1 is in an arc shape. Thus, the fluidity of the coolant during addition can be improved, and the coolant residue at the bottom of the barrel body 1 can be reduced, thereby reducing waste. At the same time, the stirring blade 32 is prevented from interfering with the bottom wall of the barrel body 1, thereby ensuring the operation of the stirring blade 32.

[0046] According to some embodiments of the present invention, referring to Figure 1-Figure 5 , the ton barrel 100 also includes a second rotating shaft 4 and a connecting member 5. The second rotating shaft 4 is arranged in the accommodating chamber 12, the second rotating shaft 4 extends along the first direction, and the second rotating shaft 4 and the first rotating shaft 31 are arranged along the second direction. The connecting member 5 is arranged between the second rotating shaft 4 and the first rotating shaft 31. Along the second direction, the connecting member 5 and the first rotating shaft 31 connected with a plurality of stirring blades 32 are sequentially connected to the outside of the second rotating shaft 4, so that the first rotating shaft 31 and the stirring blades 32 can rotate around the center of the second rotating shaft 4, so as to increase the square area of ​​the agitator 3 that can rotate and stir, thereby making the agitator 3 suitable for the use of the barrel body 1 with a larger cross-sectional area.

[0047] The battery cell processing equipment according to the second aspect of the embodiment of the utility model includes the ton barrel 100 according to the first aspect of the embodiment of the utility model.

[0048] The battery cell processing equipment according to the embodiment of the utility model, by adopting the above-mentioned ton barrel 100, is conducive to improving the use effect of the coolant, thereby improving the efficiency of the battery cell processing process and improving the quality of the processed battery cells.
