[0058] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.
[0059] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0060] On the one hand, combined with Figure 1 , Figure 2 and Figure 3 As shown in the figure, this embodiment provides a dust removal device, which includes a guide assembly 1 and a dust removal assembly 2.
[0061] The guiding assembly 1 includes a first guide plate 11, a second guide plate 12, a third guide plate 13, and a fourth guide plate 14. The first guide plate 11 and the second guide plate 12 are arranged in parallel and spaced apart to guide the first surface 1001 of the electrode sheet 100 to be dusted, and a first dust removal port 101 is formed between the first guide plate 11 and the second guide plate 12; the third guide plate 13 and the fourth guide plate 14 are arranged in parallel and spaced apart to guide the second surface 1002 of the electrode sheet 100 to be dusted, and a second dust removal port 102 is formed between the third guide plate 13 and the fourth guide plate 14.
[0062] The dust removal assembly 2 includes a first dust removal module 21 and a second dust removal module 22. The first dust removal module 21 is located above the first dust removal port 101 and removes dust from the first surface 1001 through the first dust removal port 101. The second dust removal module 22 is located below the second dust removal port 102 and removes dust from the second surface 1002 through the second dust removal port 102.
[0063] In this embodiment, the dust removal device uses a first guide plate 11 and a second guide plate 12 to guide the first surface 1001 of the electrode 100 to be dusted, and a third guide plate 13 and a fourth guide plate 14 to guide the second surface 1002 of the electrode 100 to be dusted. The first dust removal port 101 corresponding to the first dust removal module 21 is arranged between the first guide plate 11 and the second guide plate 12, and the second dust removal port 102 corresponding to the second dust removal module 22 is arranged between the first guide plate 11 and the second guide plate 12. The four guide plates can guide and support the electrode 100 to be dusted on both sides of the first dust removal port 101 and the second dust removal port 102, which helps to improve the operational stability of the electrode 100 to be dusted and prevents the electrode 100 to be dusted from being torn by suction, causing electrode damage and clogging of the dust removal device.
[0064] In some possible implementations, the positions of the first dust removal port 101 and the second dust removal port 102 are symmetrical along the electrode plate 100 to be cleaned. Thus, the suction forces of the first dust removal module 21 and the second dust removal module 22 on the electrode plate 100 to be cleaned can cancel each other out to a certain extent, which can prevent the electrode plate 100 to be cleaned from being sucked into the first dust removal port 101 or the second dust removal port 102.
[0065] In some possible implementations, the positions of the first guide plate 11 and the third guide plate 13 are symmetrical along the electrode sheet 100 to be cleaned, and the positions of the second guide plate 12 and the fourth guide plate 14 are symmetrical along the electrode sheet 100 to be cleaned.
[0066] Combination Figure 3 As shown, in some embodiments, the guide assembly 1 further includes at least one comb-tooth structure 103, which is located on at least one of the first dust removal port 101 and the second dust removal port 102. The comb-tooth structure 103 is a comb-like structure.
[0067] To further enhance the supporting effect of the guide assembly 1 on the electrode 100 to be cleaned and prevent the electrode 100 from being torn by suction, the guide assembly 1 also includes a comb structure 103 disposed on at least one of the first dust removal port 101 and the second dust removal port 102. The comb structure 103 can support the electrode 100 to be cleaned within the first dust removal port 101 and the second dust removal port 102. Based on the comb structure 103 of this embodiment, the dust removal device of this embodiment can appropriately increase the negative pressure level, thereby eliminating concerns about the electrode 100 being torn by suction.
[0068] For example, the number of comb-tooth structures 103 is one, which is located on the first dust removal port 101 or on the second dust removal port 102. For another example, the number of comb-tooth structures 103 is multiple, with at least one comb-tooth structure 103 arranged on the first dust removal port 101 and the second dust removal port 102 respectively.
[0069] Combination Figure 3 As shown, in some embodiments, there are two comb structures 103, with comb structures 103 respectively provided on the first dust removal port 101 and the second dust removal port 102.
[0070] By arranging comb-tooth structures 103 on the first dust removal port 101 and the second dust removal port 102 respectively, it is possible to prevent the electrode sheet 100 to be dusted from being sucked into the first dust removal port 101 or the second dust removal port 102.
[0071] Combination Figure 4 and Figure 5 As shown, in some embodiments, the comb structure 103 includes at least one first tooth structure 1031 and at least one second tooth structure 1032.
[0072] At least one first tooth structure 1031 and at least one second tooth structure 1032 are arranged alternately, and a gap-shaped first dust removal port 101 and / or second dust removal port 102 are formed between the at least one first tooth structure 1031 and the at least one second tooth structure 1032.
[0073] With the above arrangement, the first tooth structure 1031 and the second tooth structure 1032 are arranged alternately to form the comb structure 103. The first tooth structure 1031 and the second tooth structure 1032 can provide support and guidance for the dust removal electrode 100, and the gap between the first tooth structure 1031 and the second tooth structure 1032 can be used to form the first dust removal port 101 or the second dust removal port 102.
[0074] Combination Figure 4 and Figure 5 As shown, in some embodiments, the number of the first tooth structure 1031 and the second tooth structure 1032 are at least two.
[0075] A first tooth groove structure 1033 is formed between two adjacent first tooth structures 1031, and a second tooth structure 1032 is provided in each first tooth groove structure 1033; a second tooth groove structure 1034 is formed between two adjacent second tooth structures 1032, and a first tooth structure 1031 is provided in each second tooth groove structure 1034.
[0076] With the above arrangement, the guide component 1 can form a comb structure 103 by using its at least two first tooth structures 1031, and can also form a comb structure 103 by using its at least two second tooth structures 1032. Moreover, the two comb structures 103 are interlocked together, which further improves the guiding and supporting effect of the dust removal electrode 100.
[0077] Combination Figure 4 and Figure 5 As shown, in some embodiments, the first dust removal port 101 or the second dust removal port 102, which is provided with a comb-like structure 103, respectively includes a first suction zone 1011, a second suction zone 1012, and a blowing zone 1013. The first suction zone 1011 is located between the tip of the second convex tooth structure 1032 and the bottom of the groove of the first tooth groove structure 1033, the second suction zone 1012 is located between the tip of the first convex tooth structure 1031 and the bottom of the groove of the second tooth groove structure 1034, and the blowing zone 1013 is located between adjacent first convex tooth structures 1031 and second convex tooth structures 1032.
[0078] In this embodiment, the comb structure 103, formed by the alternation of the first convex tooth structure 1031 and the second convex tooth structure 1032, utilizes the three gaps formed between the convex tooth structure and the tooth groove structure as the first suction area 1011, the second suction area 1012, and the blowing area 1013, respectively. This allows the blowing area 1013 to be located between the first suction area 1011 and the second suction area 1012. The airflow blown out by the blowing area 1013 blows the dust on the surface of the electrode sheet 100 to be cleaned to both sides, and then it is sucked away by the first suction area 1011 or the second suction area 1012 on both sides. A stable airflow field is formed locally on the electrode sheet 100 to be cleaned. On the one hand, this can prevent the dust on the surface of the electrode sheet 100 to be cleaned from being blown out and dispersed into the external space to form secondary pollution. On the other hand, it is beneficial to prevent external dust from being sucked in by negative pressure, which would cause the electrode sheet 100 to be cleaned to be contaminated again.
[0079] Combination Figure 6 and Figure 7 As shown, in some embodiments, the spacing between at least a portion of the first tooth structure 1031 and the electrode 100 to be dusted increases along the direction from the tooth root to the tooth tip; the spacing between at least a portion of the second tooth structure 1032 and the electrode 100 to be dusted increases along the direction from the tooth root to the tooth tip.
[0080] Through the above arrangement, by designing the spacing between the first convex tooth structure 1031, the second convex tooth structure 1032 and the dust-removing electrode 100 to increase along the direction from the tooth root to the tooth tip, the first convex tooth structure 1031 and the second convex tooth structure 1032 have a shape that gradually curves upward from the root to the end. This is mainly to prevent the first convex tooth structure 1031 and the second convex tooth structure 1032 from damaging the dust-removing electrode 100.
[0081] With the upward-curving design of the first convex tooth structure 1031 and the second convex tooth structure 1032, the tip of the first convex tooth structure 1031 will gradually sink into the inner side of the tooth root of the two adjacent second convex tooth structures 1032, and the tip of the second convex tooth structure 1032 will gradually sink into the inner side of the tooth root of the two adjacent first convex tooth structures 1031. The dust removal electrode 100 mainly contacts the relatively smooth tooth root area of the first convex tooth structure 1031 and the second convex tooth structure 1032. The entire comb structure 103 has no sharp edge on the side near the dust removal electrode 100, thereby preventing damage to the dust removal electrode 100.
[0082] Combination Figure 4 and Figure 5 As shown, in some embodiments, when the comb structure 103 is located at the first dust removal port 101, at least one first convex tooth structure 1031 is located on the edge of the first guide plate 11 facing the second guide plate 12, and at least one second convex tooth structure 1032 is located on the edge of the second guide plate 12 facing the first guide plate 11.
[0083] When the comb structure 103 is located at the second dust removal port 102, at least one first convex tooth structure 1031 is located on the edge of the third guide plate 13 facing the fourth guide plate 14, and at least one second convex tooth structure 1032 is located on the edge of the fourth guide plate 14 facing the third guide plate 13.
[0084] With the above arrangement, the first convex tooth structure 1031 and the second convex tooth structure 103 forming the comb tooth structure 103 are respectively integrated on the first guide plate 11 and the second guide plate 12 arranged in parallel intervals, or integrated on the third guide plate 13 and the fourth guide plate 14 arranged in parallel intervals. By installing and fixing the four guide plates, the comb tooth structure 103 and the first dust removal port 101 and the second dust removal port 102 are installed. The structure is simple, and the disassembly and installation are convenient, which helps to improve the working reliability of the dust removal device and reduce the maintenance difficulty of the dust removal device.
[0085] Combination Figure 1 and Figure 2 As shown, in some embodiments, the dust removal device further includes at least one drive component 3; at least one drive component 3 is located at at least one position in the first guide plate 11 on the side facing away from the second guide plate 12 and the second guide plate 12 on the side facing away from the first guide plate 11, and at least one drive component 3 is used to drive the electrode 100 to be dusted through the first dust removal port 101 and the second dust removal port 102.
[0086] The drive assembly 3 arranged on one side can provide conveying power to the dust removal electrode 100.
[0087] In some possible implementations, there are two drive components 3, one of which is located on the side of the first guide plate 11 facing away from the second guide plate 12, and the other is located on the side of the second guide plate 12 facing away from the first guide plate 11. For example, one of the two drive components 3 provides tension to the electrode 100 to be cleaned, and the other provides thrust to the electrode 100. Simultaneously, both drive components 3 need to provide a certain tension to the electrode 100 in the middle to prevent it from being pulled off course by suction.
[0088] Combination Figure 1 and Figure 2 As shown, in some embodiments, each drive assembly 3 includes a drive roller 31 and a pressing roller 32. The drive roller 31 is in abutting contact with one of the first surface 1001 and the second surface 1002, and the pressing roller 32 is in abutting contact with the other of the first surface 1001 and the second surface 1002. The positions of the drive roller 31 and the pressing roller 32 are symmetrical along the electrode sheet 100 to be dusted.
[0089] With the above arrangement, the drive assembly 3 can use the drive roller 31 and the clamping roller 32 to hold the dust removal electrode 100, and can output pulling or pushing force to the dust removal electrode 100.
[0090] For example, the drive roller 31 is in abutting contact with the second surface 1002, and the pressure roller 32 is in abutting contact with the first surface 1001.
[0091] Combination Figure 6 and Figure 7 As shown, in some embodiments, at least one of the first dust removal module 21 and the second dust removal module 22 includes an outer shell 201 and an inner shell 202, respectively.
[0092] The inner shell 202 is provided with a positive pressure chamber 2021, and an air blowing port 2022 communicating with the positive pressure chamber 2021 is provided on one side of the inner shell 202.
[0093] The inner shell 202 is located inside the outer shell 201. A negative pressure chamber 2011 is provided between the outer shell 201 and the inner shell 202. Two air intake ports 2012 communicating with the negative pressure chamber 2011 are provided on one side of the outer shell 201. The two air intake ports 2012 are located on opposite sides of the air blowing port 2022.
[0094] With the above arrangement, the dry and clean gas in the positive pressure chamber 2021 is blown towards the electrode 100 to be cleaned through the air blowing port 2022. A vortex is generated on the surface of the electrode 100, causing the dust suspended on the surface of the electrode 100 to collide violently, breaking the original interface effect. Under the action of the blowing stress in the middle, the dust suspended on the surface of the electrode 100 will inevitably diffuse to both sides and finally be sucked away by the two air intake ports 2012 on both sides and enter the negative pressure chamber 2011.
[0095] In some possible implementations, the inner shell 202 is also provided with an air inlet pipe 2023 that communicates with the positive pressure chamber 2021, for continuously inputting dry and clean gas into the positive pressure chamber 2021, so that a positive pressure is formed in the positive pressure chamber 2021. The outer shell 201 is also provided with an air extraction pipe 2013 that communicates with the negative pressure chamber 2011, for extracting the gas containing dust from the negative pressure chamber 2011, so that a negative pressure is formed in the negative pressure chamber 2011.
[0096] It should be noted that the structure of the second dust removal module 22 is similar to that of the third guide plate 13 and the fourth guide plate 14. Figure 6 and Figure 7 The first dust removal module 21 shown is similar in structure to the first guide plate 11 and the second guide plate 12, except that their vertical arrangement differs. Those skilled in the art, having a full understanding of the structure of the first dust removal module 21, the first guide plate 11, and the second guide plate 12, can undoubtedly determine the structure of the second dust removal module 22, the third guide plate 13, and the fourth guide plate 14.
[0097] Combination Figure 6 and Figure 7 As shown, in some embodiments, an ultrasonic generator 203 is also provided inside the inner housing 202, and the ultrasonic generator 203 is located on the air outlet 2022.
[0098] Through the above arrangement, the high-speed airflow generates ultrasonic waves at the air outlet 2022. Due to the high frequency characteristics of ultrasonic waves, the airflow field with viscous force at the dust removal electrode 100 is broken, and the dust removal electrode 100 generates high-frequency low-amplitude vibration, making it easier for highly viscous dust to detach, thereby improving the dust removal effect of the dust removal device.
[0099] Combination Figure 6 and Figure 7 As shown, in some embodiments, when the first dust removal port 101 or the second dust removal port 102 respectively includes a first suction area 1011, a second suction area 1012 and a blowing area 1013, the first suction area 1011 is aligned with one of the suction ports 2012, the second suction area 1012 is aligned with the other suction port 2012, and the blowing area 1013 is aligned with the blowing port 2022.
