The ultrasonic screening system is a simple, practical and reliable screening system, and it is an effective solution to the current mesh plugging and embedding. It can be widely used in pharmaceutical, metallurgy, chemical, mineral processing, food and other industries that require fine screening and filtration. The screening and filtration precision is high, and it can effectively solve the screening problems caused by agglomeration, static electricity, and strong adsorption. While the screen is subjected to low-frequency vibration of the vibration motor, ultrasonic high-frequency vibration is superimposed on the surface of the screen, so that the large particles on the screen are suspended on the surface of the screen, which completely avoids the blockage of the screen. It solves the technical problems such as static electricity, easy agglomeration, strong adsorption, and blocking of screen meshes that cannot be handled by ordinary vibrating screen machines. The throughput and output of materials that are traditionally difficult to screen as well as ultra-fine materials have been significantly increased.
Features
1: The screen has a complete anti-clogging self-cleaning function, which can be screened to 800 meshes, and there is no mesh blockage at all;
2: It truly solves the screening phenomenon caused by difficult problems such as static electricity / easy agglomeration / strong adsorption, and can completely achieve effective screening with ultra-high mesh;
3: The accuracy of screening treatment can be increased by 1-70% in large steps, the output can be increased to 1-10 times, and the performance is excellent;
4: The ultrasonic generator can choose to work intermittently or continuously in 2 working modes, the voltage adopts an integrated circuit board, a fully enclosed design, and the digital CPU is precisely controlled;
5: The power supply can be automatically adjusted between 18K-40K, and the low frequency can be converted to high frequency according to the specific gravity of the material, and the transducer can work continuously for 12-24 hours;
6: The equipment does not need to be cooled and cooled, and the connection part between the vibrating screen and the ultrasonic power supply adopts an advanced aviation fully enclosed joint;
7: It can ensure that the properties and characteristics of the sieved materials are not changed.
Effect
Ultrasonic vibrating screen accelerates the separation of agglomerates, high static electricity, high precision, high density, light specific gravity, and adsorbed materials, thereby increasing the amount of sieving, reducing the number of large particles, decomposing adhering materials, and reducing the amount on the sieve. Compared with the vibrating screen without ultrasonic installation, the screening rate is increased by 5-20 times. The unique vb ultrasonic screening system application does not need to add any other screen cleaning device. It has the function of self-cleaning, the mesh is not blocked, and the fine particles with adjacent diameters can be clearly separated.
It does not change the characteristics of the screened materials, especially for the ability and scope of new material screening. There are technologies that cannot be achieved by other screening machines. The screening strength can be increased by 1-100%, which truly meets the industrial production of fine powder materials above 400 mesh. It is necessary to prevent the clogging of 50-625 mesh meshes and the impaction of similar particles on the meshes, and prolong the service life of the precious screen. It is suitable for 20 micron to 300 micron screen to separate powder, especially for difficult-to-screen materials. Significantly, the matching performance of the system will not make the operating temperature higher, and it can work continuously, especially for materials that require control of temperature rise, such as pharmaceuticals, raw materials, and thermal coatings.
