What should be paid attention to when sieving ultrasonic vibrating screen?

Ultrasonic vibrating screen.

There are 10 points to pay attention to when sifting:

1. The working input voltage of the ultrasonic resonant power supply is AC 220V, and the ultrasonic power output is drawn from the junction box on the rear panel of the chassis. Among them, the brown (red) color is the "+" pole. When wiring, you must pay attention to the voltage polarity, and do not connect the wrong wire;

2. In the case of being able to meet the production requirements, it is better to lower the power level. The maximum current should not be exceeded;

3. When the grid is not loaded, that is, when the grid is not stretched, do not turn on the ultrasound. Otherwise, it is easy to cause overcurrent of the power supply and damage to the grid and oscillator;

4. The screen must be tightened, otherwise the ultrasonic output and vibration effect will be affected;

5. The butt screw of the oscillator aviation plug must be tightened and wrapped with insulating tape to prevent dust. Pay attention to protect this connector in use;

6. Check whether the nuts of the oscillator and the connecting wire plug are tightened, and whether the oscillator and the grid are tightened before the machine starts. During use, pay attention to the protection of the connecting cable between the chassis and the oscillator, pay attention to the moisture-proof connection cable and the oscillator socket, and the connecting plug and socket are not allowed to enter the water;

7. If the material is conductive, please lengthen the ultrasonic connection line and isolate the ultrasonic resonant power supply from the screening site to prevent the material from entering the power box and causing a short circuit;

8. If you find that the fan in the case is noisy or does not rotate smoothly, please replace the fan. The chassis should be placed in a ventilated place, and other items should not be wrapped or covered;

9. When replacing the screen, scrape off the residual glue on the inner ring (resonance ring) of the grid with a sharp wallpaper knife, and do not use the angle grinder grinding wheel to prevent damage to the common ring;

10. The ultrasonic vibrating screen produced by Huanxin Machinery includes a resonant power supply, an oscillator and a grid. The three should be numbered for better use and should not be mixed with other ultrasonic shakers.

Ultrasonic vibrating screen is based on the ordinary three-dimensional vibrating screening machine with a set of ultrasonic generating device, ultrasonic using integrated circuit board, fully enclosed, aviation special interface, can work uninterrupted for 12-24 hours, no need for cooling and cooling treatment.

1) All parts above the screen tray of the vibrating screen can be cleaned with water, alcohol or high temperature sterilization

1. Seal: alcohol immersion for no more than 3 hours; High temperature sterilization does not exceed 120.

2. Screen frame: clean with a soft brush, do not use sharp sharp branches to clean the mesh to avoid deformation of the mesh; Plugging the mesh can be.

Clean with compressed air.

The ultrasonic vibrating screen converts 220V, 50Hz or 110V, 60Hz electrical energy into 18KHz high-frequency electrical energy, inputs it into an ultrasonic transducer, and turns it into 18KHz mechanical vibration, so as to achieve the purpose of efficient screening and net cleaning. On the basis of the traditional vibrating screen, the system introduces a low-amplitude, high-frequency ultrasonic vibration wave (mechanical wave) on the screen, superimposes a high-frequency and low-amplitude ultrasonic vibration wave on the screen, and the ultra-fine powder receives a huge ultrasonic acceleration, so that the material on the screen surface always maintains a suspended state, so as to inhibit the network blocking factors such as adhesion, friction, flattening, and wedge-in. It solves the screening problems such as strong adsorption, easy agglomeration, high electrostatic, high precision, high density, light specific gravity, etc., so that the screening of ultra-fine powder is no longer difficult, and it is especially suitable for users of high-quality and fine powder.

Ultrasonic vibrating screening machine is mainly used in: 400 mesh, 500 mesh, 600 mesh sieving silicon carbide, alloy powder, molybdenum powder, stainless steel powder, tungsten powder, nickel powder, cobalt powder, powder coating, quartz powder, butylmidone powder, malt powder, virus azole, coffee powder, electromagnetic powder, anode material, laser powder.

Structure and characteristics of ultrasonic vibrating screening machine:

Improve the flattening (light contact between powder and the mesh port) and slip effect of low-density powder in gravity sedimentation, improve the retention or wedge of high-density metal in the mesh port, and solve the screening problems such as strong adsorption, easy agglomeration, high electrostatic, high precision, high density, light specific gravity, etc., with superior performance! Achieve a big breakthrough in the performance of ultrasonic vibrating screen, so as to improve the screening efficiency and screening quality. Expressed by the sieving pass rate, in general, the pass rate is increased by 50%-400% compared with the non-ultrasonic vibrating screen.

1: The ultrasonic vibrating screen can control a narrow particle size range while achieving high-precision and high-mesh screening;

2: It can be used in single layer and multi-layer, and a set of intelligent ultrasonic generator can use three transducers at the same time;

3: Thorough screen self-cleaning function: more than 500 mesh screening, no mesh blockage, no screening efficiency attenuation;

4: Truly solve the screening problems such as strong adsorption, easy agglomeration, high electrostatic, high precision, high density, light specific gravity, etc.;

5: Ultrasonic vibrating screen to ensure that the characteristics of the processed materials remain unchanged;

6: The screening accuracy can be increased by 1-100%, and the output can be increased by 1-8 times;

Hope it helps.

The basic working principle of ultrasonic vibrating screen is that the high-frequency electrical oscillation generated by the oscillator is converted into sinusoidal and longitudinal oscillation by the tachometer. These fluctuations are transmitted to the pre-rod resonator and then evenly to the sieve surface.

The ultrasonic vibrating screen is based on the original rotary vibrating screen, and the ultrasonic vibrator is attached to the screen surface, and the mechanical waves generated by the instrument make the ultra-fine powder accept huge ultrasonic acceleration, so as to inhibit the network blocking factors such as adhesion, friction, translation, wedge, etc., and improve the screening efficiency and net cleaning efficiency.
