[0002] An ultrasonic vibrating screen is a screening device that combines traditional vibrating screen technology with ultrasonic technology. Based on the traditional vibrating screen, it improves screening efficiency by adding ultrasonic vibrations to the screen surface, making it particularly suitable for screening fine particulate materials. Ultrasonic vibrating screens effectively prevent clogging by fine particles, reduce material adhesion to the screen, and improve screening accuracy and processing capacity.

[0003] A three-dimensional force ultrasonic vibrating screen, disclosed in publication number CN217450895U, is easy to maintain. When maintenance is needed, this invention allows the entire screening device to be moved from inside the vibrating screen body for edge-to-edge repair of the screen mesh and frame. Compared to traditional screening device maintenance, this device is not limited by the internal space of the vibrating screen body, making maintenance much easier.

[0004] However, this easy-to-maintain three-dimensional force ultrasonic vibrating screen has the following disadvantages: it is not convenient to stack and connect multiple sets of screens and screen frames, and it is relatively inconvenient to operate when materials need to be graded and screened.

By setting the positioning component 5, multiple sets of screen barrels 1 can be stacked and installed on each other. Pulling the positioning column 501 inserts the plug-in fixing block 6 into the fixed cavity block 4. Releasing the positioning column 501 causes the positioning column 501 to insert into the positioning groove of the plug-in fixing block 6, so that multiple sets of screen barrels 1 can be quickly installed. By installing screens 302 with different mesh sizes in each screen barrel 1, the effect of multi-stage screening of materials can be achieved, and it is also easy to disassemble and maintain.

[0026] Two sets of plug-in fixing blocks 6 are fixedly installed on the top of the outer surface of the screen barrel 1. A discharge channel 7 is fixedly provided on the surface of the screen barrel 1. A docking ring 8 is fixedly provided on the top surface of the screen barrel 1. A sealing component 9 is sleeved on the surface of the docking ring 8. With the setting of the docking ring 8 and the sealing component 9, when installing multiple sets of screen barrels 1, the bottom of the upper screen barrel 1 is inserted into the docking ring 8. The rubber ring 901 and the silicone ring 902 are used to seal the connection of the screen barrel 1. The silicone ring 902 has good flexibility and can better fill the tiny gaps to avoid material leakage.

[0027] like Figure 2 As shown, the vibrating screen assembly 3 includes a vibration transmission ring 301 and a screen 302. One end of the vibration transmission ring 301 is fixedly connected to the transducer 2, and the screen 302 is fixedly installed on the top surface of the vibration transmission ring 301.

[0028] The vibrating screen group 3 is used to screen materials.

[0029] like Figure 3 As shown, the positioning component 5 includes a positioning post 501 and a spring 502. The positioning post 501 is slidably disposed inside the fixed cavity block 4, and the spring 502 is sleeved on the surface of the positioning post 501.

[0038] The support legs 12 serve to support the bottom plate 11 of the screen.

[0039] The working principle of this utility model is as follows: When installing multiple sets of screen barrels 1, the bottom of the upper screen barrel 1 is inserted into the docking ring 8. The rubber ring 901 and the silicone ring 902 are used to seal the connection of the screen barrel 1. The silicone ring 902 is flexible and can better fill the tiny gaps to avoid material leakage.

[0040] Multiple sets of screen barrels 1 are stacked and installed on each other. The positioning column 501 is pulled and the plug-in fixing block 6 is inserted into the fixing cavity block 4. The positioning column 501 is released and the reaction force of the spring 502 causes the positioning column 501 to be inserted into the positioning groove of the plug-in fixing block 6, so that multiple sets of screen barrels 1 can be installed quickly. By installing screens 302 with different mesh sizes in each screen barrel 1, the effect of multi-stage screening of materials can be achieved, and it is also convenient for disassembly and maintenance.

[0041] The ultrasonic generator 10 emits an electrical signal, which is converted into high-frequency vibration by the transducer 2 to screen the material.
