[0031] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagrams, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0032] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0033] Depend on Figures 1 to 5 As shown, this utility model provides a dust removal device for battery production, including a dust removal device 1, a blower device 2, and a battery transport platform 3.

[0034] The dust removal device 1 includes a frame 101, a battery compartment 102, a fan compartment 103, a second air duct 104, and a toothed air duct 105. The battery compartment 102 is located at the bottom of the frame 101, the fan compartment 103 is located at the bottom of one side of the frame 101, the second air duct 104 is located on the other side of the frame 101, and the toothed air duct 105 is located at the top of the frame 101. The second air duct 104 has an arc-shaped upward slope structure, which, together with the top of the frame 101, forms an irregular nozzle. A wind tunnel is located inside the frame 101. The positive electrode plate 205 divides the wind tunnel into a first wind tunnel 106 and a second wind tunnel 107. After the blower device 2 is started, a large amount of airflow is accelerated through the first air duct 204, adsorbing floating dust from the battery electrode plate, and then being blown out of the second air duct under the action of the positive and negative electrode plates. Since the height of the second air duct is 1 / 3 of its horizontal length, this structure can greatly increase the airflow velocity.

[0035] The blower device 2 includes a frame 201, a motor 202, a blower fan 203, a first air duct 204, a positive electrode plate 205, and a negative electrode plate 206. The frame 201 is fixedly connected to the fan trough 103, the blower fan 203 is fixedly connected inside the frame 201, the motor 202 is fixedly connected to the rear of the frame 201, and the motor shaft is fixedly connected to the blower fan 203. There are two frames 201, which are fixedly connected side-by-side to the fan trough 103. The first air duct 204 has a positive electrode plate 205 in the middle, and air teeth are provided on both sides of the first air duct 204. The air teeth are fixedly connected to the air tooth groove 105. There are two negative electrode plates 206, which are respectively located on both sides of the second air duct 104. The first air duct 204 is oriented towards... The lower arc-shaped protruding plate structure conforms to an aerodynamic model. The distance between the first air duct 204 and the frame 201 serves as an auxiliary air intake. The top of the negative electrode plate 206 is placed at the end of the positive electrode plate 205. The distance between the negative electrode plates 206, together with the second air duct 104, forms a simulated acceleration air duct. Two motors 202 are started, and the motors 202 drive the blower fan 203 to rotate in the frame 201, generating a large amount of airflow. After the airflow stabilizes in the wind tunnel, the battery electrode plates enter the first wind tunnel 106 from the battery slot 102 on one side. A large amount of airflow acts on the battery electrode plates, carrying away the floating dust on the surface of the electrode plates. After the floating dust is lifted, it is given additional positive charge by the positive electrode plate 205. When the airflow carries the floating dust to the negative electrode plate 206, under the electromagnetic effect, the positive and negative electric fields attract each other, adsorbing the floating dust onto the negative electrode plate 206.

[0036] The battery transport platform 3 is an automated battery transport platform. The battery transport platform 3 is located in the battery tank 102, and the positive electrode plate 205 is located above the battery transport platform 3. The battery transport platform 3 sends the battery through the battery tank 102 into the dust removal device 1.

[0037] In daily use, after assembling the device, start the two motors 202. The motors 202 drive the blower fan 203 to rotate in the frame 201, generating a large amount of airflow. This airflow disturbs the wind tunnel. After the airflow in the wind tunnel stabilizes, i.e., when the airflow is laminar, start the battery transport platform 3. The battery plates enter the first wind tunnel 106 from the battery slot 102 on one side. A large amount of airflow acts on the battery plates, carrying away the floating dust on the surface of the plates. After the floating dust floats up, it is given additional positive charge by the positive electrode plate 205. When the airflow carries the floating dust to the negative electrode plate 206, the positive and negative electric fields attract each other under the electromagnetic effect, adsorbing the floating dust onto the negative electrode plate 206. Then, under the action of the airflow, it is carried out of the first wind tunnel 106. Because the airflow speed is too fast and the flow is laminar, the floating dust will not be sucked back due to the airflow disturbance. Even if some floating dust is not removed initially, it will be adsorbed and removed in the second wind tunnel 107 divided by the positive electrode plate 205.

[0038] The first air duct 204 is an arc-shaped downward protruding structure. This structure conforms to aerodynamics. Due to atmospheric pressure, the airflow at the bottom will be accelerated by the airflow above. When the airflow passes through the second air duct 104, due to the arc-shaped groove structure and the obstruction effect of the corresponding upper frame 101, a certain airflow pressure is generated, which can greatly increase the airflow speed. This greatly enhances the acceleration effect of the fan and prevents the blown dust from having a backflow effect.

[0039] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
