Intelligently controlled four-axis variable linear equal thickness vibrating screen and vibration method

Abstract

The invention discloses an intelligently controlled four-axis variable linear equal thickness vibrating screen. The screen includes a screen box, a vibrating screen mesh, vibration damping springs, screen box supports, vibration exciters, a sensor, an integrated operational amplifier, a digital signal analyzer and an intelligent controller. The vibrating screen mesh is located at the bottom of thescreen box. The screen box is connected to the screen box supports through the vibration damping springs. Each vibration exciter consists of a variable frequency motor and a drive shaft with an eccentric block. Each driving shaft is connected to the corresponding variable frequency motor through a flexible coupling. The sensor is connected to the integrated operational amplifier through a data transmission line. The integrated operational amplifier is connected to the digital signal analyzer through a data transmission line. The digital signal analyzer is connected in series with the intelligent controller and the variable frequency motor to form a closed-loop feedback control system. A vibration exciting source of the four-axis variable linear equal thickness vibrating screen is directlyadjusted through the feedback control system, the vibration condition can be automatically adjusted without the adjustment of external vibration exciting force to make the four-axis variable linear equal thickness vibrating screen in an ideal working state to improve the screening efficiency.

Problems solved by technology

However, in the actual production process, the working conditions are complicated, and the screened materials also have a series of situations such as various types, uneven feeding, and uneven humidity, which makes the working condition of the vibrating screen poor and prone to problems such as stacking and blockage.

The existing vibrating screen cannot be automatically adjusted, and the operator must manually clean and control the vibrating screen, which not only reduces the screening efficiency, but also affects the service life of the vibrating screen

The announcement number is CN102091690A, which discloses a four-axis variable linear equal-thickness vibrating screen, which adopts gears for forced synchronization. Although the effect is good, it needs to be equipped with complex synchronization devices. The screening efficiency is not high, and it cannot cope with different working conditions and different particle sizes. , Humidity, viscosity material information feedback and adjustment
