Description

Technical Field

[0001] This utility model relates to the technical field of electroplating roll cleaning devices, specifically to an ultrasonic cleaning tank for power battery electrode rolls. Background Technology

[0002] The ultrasonic cleaning tank for power battery electrode rollers is a device specifically designed for cleaning power battery electrodes. It mainly consists of a cleaning tank, an ultrasonic generator, and a heating and temperature control system. During operation, the electrode rollers to be cleaned are placed in the cleaning tank, which is filled with a specially formulated cleaning solution. The ultrasonic generator produces high-frequency sound waves, causing a strong cavitation effect in the cleaning solution. Countless tiny bubbles are rapidly generated and instantly burst, producing a powerful impact that penetrates deep into the microscopic gaps and pores on the surface of the electrode rollers, peeling off adhering contaminants, thus achieving a highly efficient and thorough cleaning effect.

[0003] For electrode rollers, which are relatively heavy, if they are placed directly in the cleaning tank, the vibration will be transmitted to the cleaning tank along with the electrode rollers. The cavitation effect of the ultrasonic waves on their surface is weak, resulting in poor ultrasonic performance. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an improved ultrasonic cleaning tank.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows.

[0007] As a preferred technical solution, the connector includes a support rod and an elastic buffer assembly sleeved on the outer periphery of the support rod, which is composed of multi-layer composite rubber pads and built-in springs, with the multi-layer composite rubber pads distributed along the contact surface of the connector.

[0008] As a preferred technical solution, a spring is also sleeved between the support rod and the multi-layer composite rubber gasket. One end of the spring abuts against the connecting piece, and the other end of the spring is engaged with the fixing groove opened on the top surface of the outer cylinder.

[0009] As a preferred technical solution, the hollow inner cylinder includes a vertically arranged grid and a hemispherical grid connected to the lower end of the grid.

[0010] As a preferred technical solution, the outer cylinder is provided with a cooling jacket in the circumferential direction. The cooling jacket is connected to a circulating pump and a heat exchanger through pipelines, and cooling water flows through the pipelines and inside the cooling jacket.

[0011] As a preferred technical solution, the inner wall of the outer cylinder is provided with an ultrasonic reflector plate, and the ultrasonic reflector plate is made of alumina ceramic.

[0012] As a preferred technical solution, the surface of the ultrasonic reflector is configured to have an uneven shape.

[0014] The advantages and beneficial effects of this utility model are as follows: By setting a hollow inner cylinder and outer cylinder structure and evenly distributing ultrasonic generators around the circumference of the outer cylinder, the ultrasonic waves generate a highly efficient cavitation effect in the cleaning medium, thereby significantly improving the cleaning effect; at the same time, the use of an elastic buffer assembly composed of multi-layer composite rubber gaskets and springs effectively reduces the transmission of electrode roller vibration to the cleaning tank, ensuring the stability of ultrasonic cleaning; in addition, the alumina ceramic ultrasonic reflector plate set on the inner wall of the outer cylinder can enhance the reflection and distribution uniformity of ultrasonic waves, further improving cleaning efficiency and quality; when the ultrasonic reflector plate is set as an uneven plane, it can absorb ultrasonic waves that cannot be reflected, reduce vibration, and reduce noise. It has the advantages of reasonable structure, high cleaning efficiency, and stable operation, and is suitable for the large-scale and high-efficiency cleaning needs of power battery electrode rollers.

Detailed Implementation

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0017] Example 1 This embodiment provides an ultrasonic cleaning tank for power battery electrode rollers, including a hollow inner cylinder 1 for holding the electrode rollers. An outer cylinder 2 is fitted over the hollow inner cylinder 1, and an ultrasonic cleaning medium is filled between the outer cylinder 2 and the inner cylinder 1. Multiple ultrasonic generators 3 are evenly distributed around the outer cylinder 2 to generate high-frequency ultrasonic waves to create a cavitation effect in the cleaning medium. The top of the hollow inner cylinder 1 is connected and fixed to the opening of the outer cylinder 2 by a connector, which is composed of a support rod 4. An elastic buffer assembly consisting of multi-layer composite rubber gaskets 5 and built-in springs 6 is fitted around the support rod 4 to buffer the vibration generated by the electrode rollers during the cleaning process and prevent vibration from interfering with the ultrasonic cleaning effect.

[0018] Example 2 Based on Example 1, in this example, a cooling jacket 10 is provided on the outer periphery of the outer cylinder 2. The cooling jacket 10 is connected to the circulating pump and heat exchanger through a circulation pipeline. Cooling water circulates inside the cooling jacket 10 to control the temperature of the cleaning medium and prevent the cleaning fluid temperature from becoming too high due to the heat generated when the ultrasonic generator is working, which would affect the cleaning effect and equipment stability.

[0019] Example 3 Based on Example 1, in this example, an ultrasonic reflector plate 11 is fixedly installed on the inner wall of the outer cylinder 2. The ultrasonic reflector plate 11 is made of alumina ceramic material, which has good acoustic reflection performance and corrosion resistance. The surface of the reflector plate is constructed with an uneven structure, such as a pitted surface, a grid-like groove, a striped groove, or a wavy curved surface, or a combination thereof, to enhance the multiple reflections of ultrasonic waves in the cleaning tank and improve cleaning uniformity and efficiency.

[0020] Example 4 Based on Embodiment 1, in this embodiment, a spring 6 is also sleeved between the support rod 4 and the multi-layer composite rubber pad 5. One end of the spring 6 abuts against the connecting piece 7, and the other end engages with the fixing groove 8 opened on the top of the outer cylinder 2, forming a detachable buffer structure. This structure not only improves the vibration buffering effect but also facilitates disassembly and maintenance, enhancing the maintainability and service life of the equipment.

[0021] Example 5 Based on Example 1, in this embodiment, the hollow inner cylinder 1 includes a vertically arranged grid 9 and a hemispherical grid structure connected to its lower end. This structure enables the electrode roller to be stably placed in the inner cylinder and ensures that the cleaning fluid and ultrasonic waves can fully contact the surface of the electrode roller, improving cleaning uniformity and efficiency. The hemispherical bottom design helps to reduce dead zones of the cleaning fluid and improve cleaning coverage.

[0022] The working principle of this invention lies in the ultrasonic cleaning tank for power battery electrode rollers, which is based on the cavitation effect generated by ultrasound in a liquid medium. During the cleaning process, the power battery electrode rollers to be cleaned are placed in a hollow inner cylinder, which is placed inside an outer cylinder, with the space between the inner and outer cylinders filled with cleaning fluid. Multiple ultrasonic generators are evenly distributed around the circumference of the outer cylinder. When powered on, these generators produce high-frequency vibrations, which are transmitted through the cleaning fluid to form an ultrasonic field. Tiny bubbles in the liquid rapidly generate and collapse under the action of the sound waves, producing localized high pressure and high-speed jets that impact contaminants on the surface of the electrode rollers and in their micropores, achieving efficient and thorough cleaning.

[0023] To further improve cleaning efficiency and equipment stability, the inner cylinder of this invention is connected to the outer cylinder by a support rod with an elastic buffer component, effectively isolating the vibration of the electrode roller caused by its own weight and rotation, thus avoiding interference with the stability of the ultrasonic field. The inner wall of the outer cylinder is equipped with an ultrasonic reflector made of alumina ceramic material, and its surface adopts an uneven structure, such as a pitted surface, a grid-like or wavy groove, which can enhance the reflection path and distribution uniformity of ultrasonic waves and improve energy utilization. At the same time, a cooling jacket is provided around the outer cylinder, and the temperature of the cleaning fluid is controlled by a circulating cooling system to prevent high temperature from affecting the cleaning effect and equipment life.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
