It should be understood that the preferred embodiments are intended solely to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0039] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the shape, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0040] In the lithium-ion battery production process, the cleaning, filtration and drying of raw materials are key steps to ensure battery performance. The main purpose of these steps is to remove impurities, including metal and non-metal particles, from the raw materials to prevent battery performance degradation and shortened life.

[0041] In related technologies, the processing of lithium battery raw materials primarily relies on multiple independent devices for ultrasonic cleaning, filtration, and drying. These devices operate independently. For example, the material may first be cleaned with an ultrasonic cleaner, then filtered to separate solid impurities from the cleaning solution, and finally the filter paper may be transferred to a high-temperature oven for drying.

[0042] However, the related art approach of using multiple independent devices for processing presents several problems: First, the physical movement of materials between devices increases operation time and labor intensity; second, the independent operation of the devices increases the space required for the production line, reducing space utilization; and finally, the independent operation of each device results in low overall processing efficiency. Furthermore, the transfer of materials between each step can lead to secondary contamination of the raw materials by impurities, affecting the quality of the final product.

[0043] The problems solved by the present invention are described in detail below:

[0044] Reference Figure 1 , shows a battery material processing device provided by an embodiment of the present utility model, comprising:

[0045] A funnel device 1, wherein the funnel device 1 is arranged at the top of the battery material processing device and the funnel device 1 is provided with an interlayer space;

[0046] A heating component 2, wherein the heating component 2 is arranged in the interlayer space;

[0047] Filter paper 3, the filter paper 3 is arranged on the upper surface of the funnel device 1;

[0048] an ultrasonic device 4 connected to the lower surface of the funnel device 1;

[0049] The filtration device 6 is arranged on the outer surface of the battery material processing device and is connected to the space below the funnel device 1.

[0050] In a specific implementation, the funnel device 1 can be made of stainless steel and arranged at the top of the battery material processing device, and its main function is to separate solids and liquids. During the separation process, the filter paper 3 can be folded in half and formed into a specific shape (such as a funnel shape), and then the funnel-shaped filter paper 3 can be placed in the funnel device 1. By injecting the liquid to be filtered into the funnel device 1, the solid particles are intercepted by the filter paper 3, and the liquid flows through the filter paper 3 into the container or space below, thereby achieving the purpose of separation. This funnel device 1 can have the function of a separatory funnel and can also be used to separate two immiscible liquids with different densities. A piston switch 5 can be set below this funnel device 1 for adjustment, so that the liquid can flow out drop by drop, thereby accurately controlling the outflow conditions.

[0051] Furthermore, the heating component 2 can be an electric heating wire and is arranged in the interlayer space of the funnel device 1. When current passes through the electric heating wire, a certain amount of heat will be generated, and this heat will then be transferred out by the electric heating wire, thereby realizing the process of converting electrical energy into thermal energy. The upper surface of the funnel device 1 can be heated to 80±5°C within 5 minutes, and the baking time is expected to be 5-10 minutes. The surface of the filter paper 3 can be baked and heated to dryness.

[0052] Further, filter paper 3 can be arranged on the upper surface of funnel device 1, filter paper 3 specifically can adopt glass fiber filter paper, in actual application, glass fiber filter paper can be folded in half and formed into specific shape (such as funnel shape), then funnel-shaped filter paper is packed in funnel device 1, by injecting the liquid that needs to be filtered into funnel device 1, solid particles are intercepted by filter paper 3, and liquid then flows into the container below through filter paper 3, thereby reaches the purpose of separation. Glass fiber filter paper has good mechanical strength and wear resistance, is not easy to tear or damage, and therefore has certain vibration resistance. Can resist acid and alkali corrosion and the erosion of chemical solution. In addition, glass fiber filter paper adopts ultrafine glass fiber as filter layer, and is made into protective layer with synthetic fiber or natural fiber on its two sides or one side. This structure not only improves the filtration efficiency, dust holding capacity, mechanical strength and folding resistance of filter paper, but also reduces resistance, so that filter paper can also maintain good performance under vibration environment.

[0053] Furthermore, an ultrasonic device 4 may be provided in connection with the lower surface of the funnel device 1, such as Figure 2 As shown, ultrasonic device 4 can be composed of an ultrasonic generator 41, a transducer 42, an amplitude modulator 43, and an ultrasonic generator head 44. The principle of ultrasonic cleaning relies primarily on the cavitation, acceleration, and straight-through flow effects of ultrasonic waves in liquids. These effects work together to control the device to operate in a water bath, with parameters set at a frequency of 53 kHz, an ultrasonic power of 40%, and an ultrasonic duration of 15 minutes to disperse, emulsify, and exfoliate the dirt layer, thereby achieving the cleaning effect.

[0054] Furthermore, a filtration device 6 can be provided, and the filtration device 6 is provided on the outer surface of the battery material processing device and is connected to the space below the funnel device 1. The filtration device 6 can be a vacuum filtration device, which can be connected to the relatively closed environment of the liquid tank for vacuuming. After the ultrasonic cleaning is completed, the piston switch 5 can be opened, the drain control valve 8 can be closed, and the conical rubber plug 10 can be fastened under a negative pressure environment. When the vacuum filtration is opened under this condition, rapid filtration can be performed to improve the filtration efficiency.

[0055] In one embodiment of the present invention, the battery material processing device further includes:

[0056] The piston switch 5 is arranged at the discharge port of the funnel device 1.

[0057] In practical applications, a piston switch 5 can be provided at the discharge port of the funnel device 1. The piston switch 5 can be adjusted to allow the liquid to flow out drop by drop, thereby precisely controlling the outflow conditions. Before ultrasonic cleaning, the piston switch 5 can be closed, or the flow rate can be precisely controlled to inject the required liquid while ultrasonic cleaning is performed. After ultrasonic cleaning is completed, the piston switch 5 can be fully opened, or rapid filtration can be performed to improve filtration efficiency.

[0058] In one embodiment of the present invention, the battery material processing device further includes:

[0059] The waste liquid receiving tank 7 is arranged below the liquid discharge port of the funnel device 1 .

[0060] In a specific implementation, a waste liquid receiving tank 7 can be set below the discharge port of the funnel device 1 to collect and discharge the waste liquid filtered out by the funnel device 1, thereby facilitating the collection and treatment of the waste liquid and reducing liquid overflow and environmental pollution during operation.

[0061] In one embodiment of the present invention, the battery material processing device further includes:

[0062] The liquid discharge control valve 8 is provided at the liquid discharge port of the waste liquid receiving tank 7 .

[0063] In practical applications, a drain control valve 8 can be set at the drain port of the waste liquid tank 7. The waste liquid in the waste liquid tank can be discharged by controlling the drain control valve 8, and the drain control valve 8 can be controlled to remain in a closed state when necessary, thereby providing a sealed condition for the funnel vacuum filtration.

[0064] In one embodiment of the present invention, the battery material processing device further includes:

[0065] An arc-shaped gasket 9 is connected to a side of the filter paper 3 close to the funnel device 1 .

[0066] In a specific implementation, an arc-shaped gasket 9 can be provided on the side of the filter paper 3 close to the funnel device 1. The arc-shaped gasket 9 can be made of stainless steel and can be used to provide support for the filter paper 3 to prevent the filter paper 3 from being damaged.

[0067] In one embodiment of the present invention, the battery material processing device further includes:

[0068] A liquid level display tube 11 is provided on the outer surface of the battery material processing device and is connected to the interior of the waste liquid receiving tank 7 via a liquid level control valve 12 .

[0069] In a specific implementation, a liquid level display tube 11 can be set and the liquid level display tube 11 can be set on the outer surface of the battery material processing device and the liquid level display tube 11 is connected to the inside of the waste liquid receiving tank 7 through a liquid level control valve 12 to display the liquid level of the waste liquid receiving tank 7, so as to facilitate timely discharge of excess waste liquid, wherein the liquid level control valve 12 can be used to control the flow rate of the liquid level display tube 11.

[0070] In one embodiment of the present invention, the battery material processing device further includes:

[0071] The rubber stopper 10 is arranged at the top end of the liquid level display tube 11 .

[0072] In practical applications, since the liquid level display tube 11 needs to be connected to the outside air to meet the air pressure conditions in order to display the liquid level, and the internal state of the device needs to be kept closed during vacuum filtration, a rubber stopper 10 can be provided to provide a closed condition for funnel vacuum filtration, and the rubber stopper 10 can be a conical rubber stopper.

[0073] In one embodiment of the present invention, the ultrasonic device 4 includes:

[0074] An ultrasonic generating head 44, which is arranged at one end of the ultrasonic device 4 close to the funnel device 1;

[0075] an amplitude modulator 43 connected to an end of the ultrasonic generator 44 away from the funnel device 1;

[0076] A transducer 42, wherein the transducer 42 is connected to an end of the amplitude modulator 43 away from the ultrasonic generator 44;

[0077] The ultrasonic generator 41 is connected to the end of the transducer 42 away from the amplitude modulator 43 .

[0078] In the specific implementation, Figure 2 As shown, the ultrasonic device 4 can be composed of an ultrasonic generator 41, a transducer 42, an amplitude modulator 43, and an ultrasonic generator head 44. The ultrasonic generator 41 converts industrial-frequency alternating current into ultrasonic-frequency oscillations with a certain power output, transferring energy and stimulating vibrations in objects. The transducer 42 is the core component of the ultrasonic device 4. Its primary function is to convert input electrical power into mechanical power (i.e., ultrasonic waves) and then transmit it, while consuming very little power itself. It utilizes the piezoelectric effect of piezoelectric materials to convert electrical energy into mechanical vibrations, thereby generating ultrasonic waves. These ultrasonic waves can propagate through the medium and are used to achieve the desired function. The amplitude modulator 43 can increase the amplitude of the ultrasonic wave, and it is a circuit that changes with the modulation signal; the ultrasonic generator head 44 can convert the high-frequency voltage generated by the ultrasonic generator into high-frequency mechanical vibration through the transducer 42, and the generated mechanical vibration is adjusted in amplitude by the amplitude modulator 43 and then transmitted to the ultrasonic generator head 44; after the ultrasonic wave is started, the high-frequency vibration wave of tens of thousands of times per second is transmitted to the funnel device 1, forming a transmission resonance with the funnel device 1, and the cavitation effect of the ultrasonic wave in the liquid will disperse, emulsify and peel off the dirt layer, thereby achieving the purpose of cleaning.

[0079] In one embodiment of the present invention, the heating component 2 is an electric heating wire, and the filter paper 3 is glass fiber filter paper.

[0080] In practical applications, the heating element 2 can be configured as an electric heating wire, and the filter paper 3 can be glass fiber filter paper. When current passes through the electric heating wire, a certain amount of heat is generated, which is then transferred by the electric heating wire, thereby converting electrical energy into thermal energy. The upper surface of the funnel device 1 can be heated to 80±5°C within 5 minutes. The baking time is expected to be 5-10 minutes, and the surface of the filter paper 3 can be baked and heated to dryness. In practical applications, the glass fiber filter paper can be folded in half and formed into a specific shape (such as a funnel shape). The funnel-shaped filter paper is then loaded into the funnel device 1. By injecting the liquid to be filtered into the funnel device 1, solid particles are intercepted by the filter paper 3, while the liquid flows through the filter paper 3 into the container below, thereby achieving the purpose of separation. Glass fiber filter paper has excellent mechanical strength and wear resistance, is not easily torn or damaged, and therefore has a certain degree of vibration resistance. It can resist acid and alkali corrosion and chemical solution erosion. In addition, glass fiber filter paper uses ultra-fine glass fiber as the filter layer, and is covered with synthetic fiber or natural fiber as a protective layer on both sides or one side. This structure not only improves the filtration efficiency, dust holding capacity, mechanical strength and folding resistance of the filter paper, but also reduces resistance, allowing the filter paper to maintain good performance even in a vibration environment.

[0081] In one embodiment of the present invention, there are two ultrasonic devices 4 .

[0082] In a specific implementation, the number of ultrasonic devices 4 can be set to two, and the two ultrasonic devices 4 can be connected to both sides of the lower surface of the funnel device 1 respectively, so as to provide a double cleaning effect, ensure that the raw materials are cleaned more thoroughly, and reduce residual impurities.

[0083] The following describes the technical effects of the present invention compared with the related technical solutions with reference to comparative experimental examples:

[0084] Specifically, the raw material separator of lithium battery can be used to extract and detect metal and non-metallic impurities, and the time required to test the same sample at the same time using the test equipment of the control group and the test equipment of the experimental group;

[0085] The control group was processed sequentially using an ultrasonic cleaner, a filtration device, and a high-temperature oven to extract metal and non-metallic impurities from the lithium battery raw material diaphragm and ensure that the extracted impurities met the conditions for subsequent testing. The time required for the sample, T1, was calculated.

[0086] The experimental group used the battery material processing device provided by the utility model to perform corresponding processing to extract metal and non-metallic impurities from the lithium battery raw material separator and ensure that the extracted impurities meet the conditions for subsequent testing. The time T2 required for the sample was calculated; the experimental results are shown in Table 1 below:

[0087] Table 1: Time performance comparison table of control group and experimental group

[0088]

[0089] It can be seen from the contents of Table 1 that the experimental group can save 40 minutes compared with the control group. That is, the battery material processing device provided by the utility model can greatly reduce the processing time of the impurity extraction process. The operation method is simple, the steps are concise, the time taken to measure impurities is short, and the equipment occupies a small area, which significantly improves the overall detection efficiency.

This device integrates ultrasonic cleaning, filtration, and high-temperature drying functions, simplifies operational steps, avoids frequent handling of intermediate products between devices during the processing process, and improves processing efficiency and space utilization. Through integrated processing, impurities can be quickly and effectively extracted and dried in a closed system, avoiding the risk of secondary contamination, ensuring the cleanliness and quality of battery raw materials, and facilitating further analysis of impurities. For example, after ultrasonic cleaning of lithium-ion battery raw materials, the metal and non-metallic impurities in the lithium-ion battery raw materials can be stripped away from the raw materials, and the impurities can be quickly filtered out and dried, making it convenient to place the impurity-laden glass fiber filter membrane into the carrier box. The cleanliness tester Jomesa can then be used to quickly analyze the particle size, particle number, and metal and non-metallic composition of the impurities.
