（精细筛粉机）是将220v、50hz或110v、60hz电能转化为18khz的高频电能，输入超声换能器，将其变成18khz机械振动，从而达到高效筛分和清网的目的，使超微细粉筛分成为易事。 JH-C series ultrasonic vibrating screen (fine sifter) converts 220v, 50hz or 110v, 60hz electric energy into 18khz high-frequency electric energy, input the ultrasonic transducer, and turn it into 18khz mechanical vibration, so as to achieve efficient screening The purpose of Heqing Net makes ultra-fine powder screening easy. This system introduces a low-amplitude, high-frequency ultrasonic vibration wave (mechanical wave) on the screen based on the traditional vibrating screen to improve the screening performance of ultrafine powder. Especially suitable for users with high added value fine powder.
）是附加在筛网上的超声振动波（机械波），使超微细粉体接受巨大的超声加速度，从而抑制粘附、摩擦、平降、楔入等堵网因素，提高筛分效益和清网效益。 Ultrasonic vibration sieve ( fine sieve powder machine ) is an ultrasonic vibration wave (mechanical wave) attached to the screen, so that ultra-fine powders receive huge ultrasonic acceleration, thereby inhibiting network blocking factors such as adhesion, friction, leveling down, wedging, etc. Improve screening efficiency and net cleaning efficiency. Ultrasonic vibrating screen is to convert 220V, 50Hz or 110V, 60Hz electric energy into 18KHz high-frequency electric energy, input the ultrasonic transducer, and turn it into 18KHz mechanical vibration, which greatly improves the various effects of the vibrating screen and achieves efficient screening. The purpose of Heqing. The general vibrating screen vibrates at a frequency of 1460 times per second, while the ultrasonic vibrating screen has a frequency of 36,000 times per second, which truly realizes the combination of sound waves and vibratory frequency. The sieve stands out from the ordinary light screening equipment, and has become the favorite high-efficiency screening equipment for ultra-fine segment customers.
Improve the low-density powder's leveling down (light contact between the powder and the mesh port) and slip effect in the gravity settlement, improve the retention or wedging of high-density metal in the mesh port, improve the adhesion effect of electrostatic powder, and improve the sieve. Separation efficiency and screening quality. It is expressed by the sieving pass rate. In general, the pass rate is increased by 50% -400% than that without ultrasonic vibrating screen.
⑴ reduce or not produce clean-up time;
⑵No powder pollution caused by bouncing ball and other auxiliary materials;
(3) Maintain the size of the mesh port and stabilize the screening accuracy;
⑷ Decompose adherent substances and reduce the objects on the screen;
⑸ Reduce the number of screenings.
The ultrasonic vibrating screen (fine sieving powder machine) produced by our company is a patented product. It is designed as an external transducer according to customer needs, so that it is not necessary to open the sieve when checking or replacing the transducer. Some of the more important materials have very high electrical conductivity. The external structure of the transducer is strong, so that the transducer is not in contact with the logistics. This ensures that the transducer is not conductive, so that the transducer can continue to work.
1. When changing the screen, you must first remove the ultrasonic vibration sieve beam ring and take out the network frame, and then you can change the screen, so you need to prepare a wrench in advance to unload the beam ring wire;
2. The commonly used grid structure for the ultrasonic vibration screen is an adhesive grid frame, that is, the screen is glued to the grid frame. When changing the screen, a special grid cleaner and instant adhesive are required to prepare the old screen. Replacement of the mesh with a new screen.
3. In order to maintain the effect of instant glue, you need to prepare a clean soft cloth dipped in acetone to clean up greasy magazines on the grid;
的超高频率要求筛网的张紧度必须达标，因此建议使用专业的绷网工具进行辅助，如果实在没有需要准备橡胶锤进行辅助。 4. As the ultra-high frequency of the ultrasonic vibration sieve requires that the tension of the screen must meet the standard, it is recommended to use a professional stretcher tool to assist. If there is really no need to prepare a rubber hammer to assist.
5. After bonding the screen and the grid with professional glue, let it stand for at least 12h at a constant temperature until the glue is completely dry before visitors can use it. It can be reduced in summer (above 8h) as appropriate.
