Description

A dual-axis synchronous vibrating screen for active ash solid waste particles

technical field

The invention relates to a dual-axis synchronous vibrating screen for active ash solid waste particles, which can automatically separate large and small particles screened out into different areas, and belongs to the technical field of screening.

Background technique

The activity of lime depends on its structure, and the structure of lime is closely related to calcination temperature and calcination time. The microstructure that affects the reactivity of lime includes bulk density, porosity, specific surface area, and grain size of CaO minerals. The smaller the crystal grain, the larger the specific surface area, the higher the porosity, the higher the lime activity, and the stronger the chemical reaction ability.

The vibrating screen works by using the reciprocating rotation vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane circular vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. Its vibration track is a complex space curve. The projection of the curve on the horizontal plane is a circle, while the projection on the vertical plane is an ellipse. The vibration amplitude can be changed by adjusting the excitation force of the upper and lower rotating weights. And adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the motion track of the screen surface and change the motion track of the material on the screen surface.

However, during vibratory sieving, the existing vibrating sieves cannot automatically put the sieved large particles into another area to form a classification.

For example, the Chinese patent with the application number CN202111072978.5 discloses a dual-axis synchronous vibrating screen for mine solid waste particles. On the first filter screen, when there is mineral material falling on the first filter screen, the turntable is controlled to rotate, so that the turntable drives the top block to rotate and jack up the first filter screen, and at the same time, the repulsion of the main magnet block and the auxiliary magnet block makes the second The lameness of the first filter screen is larger. When the first filter screen is lame up and down, the extension rod will drive the rotary plate to move up and down. After the rotary plate moves downward, the mineral material will be introduced into the vibrating screen body. When moving down, the air bag will be squeezed, so that the gas will be ejected and the impurities in the mineral material on the first filter screen will be blown through the air outlet. Through the above operations, the poured mineral material can be controlled, and when the efficiency needs to be accelerated , the speed at which the first filter screen shakes off the mineral material can be accelerated by controlling the rotation rate of the turntable. However, it is not possible to automatically put the sieved large particles into another area during vibratory screening to form a classification, which is not conducive to the improvement of screening efficiency.

Therefore, it is very necessary to design a dual-axis synchronous vibrating screen for active ash solid waste particles that can automatically separate the large and small particles from the screen into different areas.
