DETAILED DESCRIPTION

[0022] The following is a detailed description of a negative electrode material processing ultrasonic vibration screen body anti-blocking device provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternative methods for implementation; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the utility model provides an anti-blocking device for an ultrasonic vibrating screen body of a negative electrode material processing, comprising: an ultrasonic vibrating screen body 1 and a screening part 8; a vibration part 7, installed on the screening part 8, the vibration part 7 comprising: a dual-axis motor 701; two cranks 702, respectively installed at both ends of the dual-axis motor 701; a connecting piece 703, movably installed on the crank 702, for connecting the screening part 8 and the crank 702.

[0024] The vibration part 7 drives the screening part 8 for efficient screening through the vibration force generated by the dual-axis motor 701. High-frequency vibration helps prevent material accumulation on the screen, reduce screen blockage, and keep the screen clean. The dual-axis motor 701 serves as the power source of the vibration part 7 and provides continuous and stable vibration force to ensure screening efficiency. The vibration frequency and amplitude are controlled by adjusting the rotation speed and eccentricity of the dual-axis motor 701 to meet the screening requirements of different materials. The crank 702 converts the rotational motion generated by the dual-axis motor 701 into reciprocating vibration of the vibration part 7 to achieve the vibration effect required for screening. The connecting piece 703 connects the vibration part 7 with the screening part 8 to ensure that the vibration force can be effectively transmitted to the screen.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, multiple mounting parts 5 are detachably mounted on the ultrasonic vibration screen body 1, and the multiple mounting parts 5 are distributed in a ring array on the ultrasonic vibration screen body 1; an elastic member 6 is mounted on the mounting parts 5 and the screening part 8.

[0026] Multiple mounting parts 5 provide a detachable connection between the ultrasonic vibration screen body 1 and the screening part 8, which is convenient for the assembly, maintenance and replacement of parts of the equipment. By being distributed in a circular array on the ultrasonic vibration screen body 1, the supporting force on the screening part 8 is ensured to be uniform, thereby enhancing the stability and durability of the structure.

[0027] like Figure 3 and Figure 4 As shown, the screening part 8 includes: a first screen frame 801 and a second screen frame 803; a support member 804, installed on the first screen frame 801, for supporting the dual-axis motor 701; a plurality of elastic members 802, installed on the first screen frame 801 and the second screen frame 803, and a connecting member 703 movably installed on the second screen frame 803.

[0028] The first screen frame 801 and the second screen frame 803 are both equipped with screens, which are responsible for accurately separating the particles of the materials and classifying them into different grades according to their sizes.

[0029] The connecting piece 703 connects the vibration part 7 with the second screen frame 803, ensuring that the vibration force can be effectively transmitted to the screen, so that the second screen frame 803 can have a certain flexibility under the action of vibration, so as to better adapt to the screening requirements of different materials. The various components of the screening part 8 work together to achieve efficient material screening and effective screen blocking, thereby improving production efficiency and product quality.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a plurality of grooves 4 are provided on the ultrasonic vibration screen body 1 . The grooves 4 are distributed in a circular array on the ultrasonic vibration screen body 1 . The number of the grooves 4 is consistent with the number of the mounting parts 5 .

[0031] The groove 4 provides a precise installation position for the mounting member 5, ensuring that the mounting member 5 can be accurately installed on the ultrasonic vibration screen body 1. Through the preset groove 4, the installation process of the mounting member 5 is simpler and faster, which improves the assembly efficiency of the equipment. The groove 4 serves as a support point for the mounting member 5, which helps to disperse and bear the weight and vibration from the screening part 8, enhance the stability of the entire equipment, ensure the long-term stable operation of the equipment, and facilitate regular cleaning of the screening part 8 to reduce clogging.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the feed piece 2 is installed on the ultrasonic vibration screen body 1, an electric valve is provided on the feed piece 2, and an observation window is embedded on the ultrasonic vibration screen body 1.

[0033] The feed piece 2 is used to control the material flow rate. The electric valve accurately controls the material flow rate entering the screening section 8 to ensure the continuity and stability of the screening process and avoid excessive material entering at one time and accumulating on the screening section 8, thereby causing the screening section 8 to be blocked.

[0034] The observation window embedded in the ultrasonic vibrating screen body 1 allows the operator to monitor the screening process in real time and promptly understand the working status of the screen and the screening status of the material. Through the observation window, possible problems that may occur during the screening process, such as material blockage, screen fragility, etc., can be discovered in time, so that corresponding measures can be taken to deal with them.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the controller 3 is installed on the ultrasonic vibration screen body 1, and the controller 3 includes a display screen and control buttons.

[0036] The display screen can show the working status of the ultrasonic vibrating screen in real time, including key parameters such as screening progress, equipment running time, current frequency, etc., so that the operator can fully understand the operation of the equipment. When the equipment is abnormal, the display screen will display a fault code or warning message to help the operator quickly locate the problem and perform maintenance.

[0037] The control buttons are intuitive and easy to understand, allowing the operator to start and stop the equipment, adjust the frequency, switch modes, and perform other operations to achieve precise control of the screening process. In emergencies, the operator can immediately interrupt the equipment operation through the emergency stop button to ensure production safety.

[0038] like Figure 4 As shown, the mesh diameter of the first sieve frame 801 is larger than the mesh diameter of the second sieve frame 803 , and the surfaces of the first sieve frame 801 and the second sieve frame 803 are both coated with a polyurethane coating.

[0039] The mesh diameter of the first screen frame 801 is larger than that of the second screen frame 803, so that the material can be firstly coarsely screened to remove larger particles during the screening process, and then finely screened by the second screen frame 803 to improve the screening accuracy. Through two-stage screening, the burden of a single screen can be reduced and excessive blockage can be avoided, thereby improving the overall screening efficiency.

[0040] The polyurethane coating has excellent wear resistance and can effectively protect the surface of the screen frame from material friction and impact, extending the service life of the equipment. The polyurethane coating can also prevent corrosion of the metal part of the screen frame by moisture, chemical materials, etc., ensuring the stability of the equipment in harsh environments.

[0041] The technical solution provided by the utility model, when in use, controls the flow of materials entering the ultrasonic vibration screen body 1 through the feed piece 2 through the electric valve, and the screening part 8 performs double screening on the materials. The dual-axis motor 701 is operated to drive the crank 702 to rotate synchronously, and the crank 702 drives the connecting piece 703 to rotate, thereby driving the first screen frame 801 and the second screen frame 803 to move, and the elastic piece 1 6 and the elastic piece 2 802 enable the first screen frame 801 and the second screen frame 803 to move within the moving range.

[0042] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
