[0030] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0031] Please refer to Figures 1 to 9 This utility model provides an electrode dust removal device, which includes a dust removal box 1. The dust removal box 1 is provided with a dust blowing chamber 11 connected to a positive pressure air source and a first dust suction chamber 12 and a second dust suction chamber 13 connected to a negative pressure air source. The bottom of the dust removal box 1 is provided with a slit hole 14, a first dust suction hole 15 and a second dust suction hole 16. The slit hole 14 is connected to the dust blowing chamber 11, the first dust suction hole 15 is connected to the first dust suction chamber 12, and the second dust suction hole 16 is connected to the second dust suction chamber 13.

[0032] As can be seen from the above description, the beneficial effects of this utility model are as follows: This utility model designs a non-contact electrode dust removal device. In practical applications, the electrode passes directly below the electrode dust removal device. The electrode dust removal device has a positive pressure blowing chamber 11 in the middle corresponding to the slit hole 14 for blowing dust, and negative pressure suction chambers (first and second suction chambers) on both sides corresponding to the first and second suction holes for suction. The cooperation between the positive pressure blowing chamber 11 and the negative pressure suction chamber can achieve non-contact dust removal. That is, by combining positive pressure airflow (blowing dust) with negative pressure adsorption (suction), physical contact with the electrode is avoided, achieving non-contact cleaning and reducing scratches or deformation. At the same time, when the concentrated airflow in the blowing chamber 11 removes dust, the suction chamber promptly removes contaminants, reducing secondary adhesion and improving the dust removal effect.

[0033] Furthermore, the electrode dust removal device of this utility model also includes an air inlet 2, which is located inside the dust blowing chamber 11. The air inlet 2 is provided with an air inlet channel, and the dust removal box 1 is provided with an air inlet 17, which is connected to the air inlet channel.

[0034] As can be seen from the above description, the addition of air inlet 2 allows external air to be evenly introduced into the dust blowing chamber 11 through the air inlet channel, thus avoiding excessively strong or weak local airflow.

[0035] Furthermore, in the electrode dust removal device of this utility model, the air inlet channel includes an air guide channel 21 and a plurality of diversion channels 22. The air guide channel 21 is connected to the air inlet 17, and the diversion channels 22 are respectively connected to the air guide channel 21 and the dust blowing chamber 11.

[0036] As described above, the air inlet channel is divided into an air guide channel 21 and multiple diversion channels 22. The diversion channels 22 disperse the airflow to different areas of the dust blowing chamber 11 to avoid local airflow being too strong or too weak and to expand the cleaning coverage area.

[0037] Furthermore, in the electrode dust removal device of this utility model, the dust blowing chamber 11 includes a first chamber 111 and a second chamber 112, the first chamber 111 and the second chamber 112 are connected, and the cross-sectional shape of the second chamber 112 is funnel-shaped.

[0038] As described above, the funnel-shaped cross-section narrows the airflow channel, increases airflow velocity, enhances dust blowing force, and improves the removal efficiency of micron-sized pollutants. In practical applications, the second cavity 112 may include a first air cavity, a second air cavity, and a third air cavity connected in sequence. The first air cavity has a rectangular cross-section, the second air cavity has an inverted triangular cross-section, and the third air cavity has a rectangular cross-section with a narrow slit.

[0039] Furthermore, the electrode dust removal device described in this utility model also includes a plasma generator, which is located inside the air guide channel 21.

[0040] As described above, the plasma generator may include components such as power-conducting wires. In practical applications, it can generate ions to blow out plasma wind, avoiding secondary pollution from dust due to electrostatic adsorption, and thus achieving better dust removal effect.

[0041] Furthermore, the electrode dust removal device of this utility model also includes an antistatic device 3, which is disposed on the dust removal box 1.

[0042] As described above, the dust collection box 1 is equipped with an anti-static device 3, which works in conjunction with the plasma generator to provide double anti-static protection, ensuring that the surface potential of the electrode plate approaches zero and eliminating the risk of static electricity accumulation.

[0043] Furthermore, the electrode dust removal device of this utility model also includes an iron filings removal device 4, which is disposed on the dust collection box 1. In practical applications, the iron filings removal device 4 is in the shape of a drum.

[0044] As described above, the dust collection box 1 is equipped with an iron filings removal device 4, which can preferentially remove conductive metal filings through magnetic attraction or eddy current separation, specifically remove metal particles, reduce the risk of battery short circuits, reduce the number of metal particles entering the dust collection system, and extend the service life of the equipment.

[0045] Furthermore, the electrode dust removal device of this utility model also includes a mounting frame 5 and a cylinder 51 disposed on the mounting frame 5, wherein the piston rod of the cylinder 51 passes through the mounting frame 5 and is connected to the dust removal box 1.

[0046] As described above, by controlling the lifting and lowering of the dust collection box 1 by the cylinder 51, the distance between the dust collection box 1 and the electrode sheet located below it can be effectively adjusted to maintain the best blowing and suction effect. At the same time, it can also be adapted to electrode sheets of different thicknesses.

[0047] Furthermore, the electrode dust removal device of this utility model also includes a guide frame 52, which is movably mounted on the mounting frame 5, and the bottom of the guide frame 52 is connected to the dust removal box 1.

[0048] As described above, the guide frame 52 is movably mounted on the mounting frame 5 and connected to the dust collection box 1 at the bottom. The guide frame 52 restricts the horizontal displacement of the dust collection box 1, prevents the cylinder 51 from shaking when it extends or retracts, and ensures the stability of the vertical movement of the dust collection box 1.

[0049] Furthermore, the electrode dust removal device described in this utility model also includes a hand-operated valve 53, which is disposed on the mounting bracket 5. In practical applications, a corresponding hand-operated valve 53 is provided, through which the opening state of the cylinder 51 can be controlled. A corresponding button can be provided on the hand-operated valve for control.

[0050] Please refer to Figures 1 to 9 A preferred embodiment of this utility model is as follows: an electrode dust removal device, comprising a dust collection box 1, wherein the dust collection box 1 is provided with a dust blowing chamber 11 connected to a positive pressure air source and a first dust suction chamber 12 and a second dust suction chamber 13 connected to a negative pressure air source. The dust blowing chamber 11 includes a first cavity 111 and a second cavity 112, the first cavity 111 and the second cavity 112 communicating with each other, and the cross-sectional shape of the second cavity 112 being funnel-shaped. Correspondingly, the bottom of the dust collection box 1 is provided with a slit hole 14, a first dust suction hole 15, and a second dust suction hole 16; wherein the slit hole 14 communicates with the dust blowing chamber 11, the first dust suction hole 15 communicates with the first dust suction chamber 12, and the second dust suction hole 16 communicates with the second dust suction chamber 13.

[0051] In this embodiment, as Figures 3 to 9 As shown, the electrode dust removal device also includes an air inlet 2, which is located inside the dust blowing chamber 11. The air inlet 2 is provided with an air inlet channel, which includes a guide channel 21 extending along the horizontal length direction and multiple diversion channels 22 extending along the horizontal width direction. An air inlet 17 is provided on the top of the dust removal box 1. The guide channel 21 is connected to the air inlet 17, and the diversion channels 22 are connected to the guide channel 21 and the dust blowing chamber 11 respectively.

[0052] In this embodiment, the electrode dust removal device also includes a plasma generator located within the air guide channel 21 to generate plasma air. Furthermore, as... Figure 1 as well as Figure 3 As shown, the electrode dust removal device also includes an antistatic device 3 and an iron filings removal device 4 respectively disposed on both sides of the dust removal box 1, so as to perform antistatic operation and iron filings removal operation on the electrode.

[0053] In this embodiment, as Figure 1 , Figure 2 as well as Figure 5 As shown, the electrode dust removal device also includes a mounting frame 5 and a cylinder 51 mounted on the mounting frame 5. The mounting frame 5 is located above the dust collection box 1, and the cylinder 51 is mounted on the upper surface of the mounting frame 5. The piston rod of the cylinder 51 passes through the mounting frame 5 and connects to the dust collection box 1 below. Two guide frames 52 spaced at a certain distance are also provided on the mounting frame 5. The two guide frames 52 are movably mounted on the mounting frame 5, and their bottoms are connected to the dust collection box 1, facilitating the cylinder 51 to drive the dust collection box 1 to move up and down.

[0054] In summary, the electrode dust removal device provided by this utility model has multiple air inlets 17 on the upper surface of the dust collection box 1, which are connected to the air guide channel 21 (extending horizontally) inside the air inlet component 2. The air inlet component 2 also has multiple diversion channels 22 extending horizontally, which are connected to the air guide channel 21 and the dust blowing chamber 11 respectively. Therefore, the air blown in from the air inlets 17 can sequentially enter the dust blowing chamber 11 through the air guide channel 21 and the diversion channels 22, and then be blown out from the narrow slit hole 14 of the dust blowing chamber 11 to remove dust from the electrode. Simultaneously, the first and second suction chambers located on both sides of the dust blowing chamber 11 are connected to a negative pressure suction system through openings 18, allowing dust to be drawn into the first suction chamber 12 and the second suction chamber 13 through the first suction hole 15 and the second suction hole 16 at the bottom of the dust collection box 1 for dust removal.
