Description

Four-layer complex frequency screen

Technical Field

The utility model relates to a shale shaker technical field especially relates to a four-layer complex frequency sieve.

Background

The vibrating screen operates by utilizing reciprocating rotary type vibration generated by vibrator excitation. The upper rotary heavy hammer of the vibrator makes the screen surface generate plane rotary vibration, the lower rotary heavy hammer makes the screen surface generate conical surface rotary vibration, and the combined effect makes the screen surface generate re-rotary vibration. The vibration locus is a complex space curve. The curve is projected as a circle in the horizontal plane and as an ellipse in the vertical plane. The amplitude can be changed by adjusting the exciting force of the upper and lower rotary weights, and the curve shape of the motion trail of the screen surface can be changed and the motion trail of the material on the screen surface can be changed by adjusting the space phase angle of the upper and lower rotary weights.

According to the development of the times, the vibrating screen is widely used in the screening field, the screening effect is continuously improved in the screening process, the development of a wider and longer screening machine becomes a research and development target, the existing technical scheme adopts a single layer and double layers, the screening efficiency is low, the processing capacity is low, dust is leaked out, and the environmental protection performance is poor, so that a four-layer complex frequency screen is provided to solve the problems.

SUMMERY OF THE UTILITY MODEL

In order to overcome the problems in the related art, the embodiment of the utility model provides a four-layer complex frequency screen,

solves the problems of leakage of the dust of the prior complex frequency screen and poor environmental protection performance.

The embodiment of the utility model provides a four layers of compound frequency sieves, including sealed lid, vibration exciter, sieve case, sieve core, spring-loaded support, transmission, motor and collet, the top of collet is connected with the sieve case that the slope form set up, the motor is installed in the front that the top of collet is located the sieve case, and the output shaft of motor has transmission through the coupling joint, be connected through transmission between motor and the vibration exciter, the vibration exciter is installed on the sieve case, the internally mounted of sieve case has the sieve core, and the sieve core can be used to fixed sieve.

Furthermore, a sealing cover for sealing is mounted at the top of the screen box, so that dust in the screen box can be prevented from leaking.

Furthermore, the screen box is also provided with an elastic support connected with the vibration exciter.

Further, the sieve core is divided into four layers and is obliquely arranged inside the sieve box.

The embodiment of the utility model provides a technical scheme has following beneficial effect: through adopting the sieve case not to vibrate, the structural style of screen frame vibration has avoided the dust to leak, better satisfied the environmental protection requirement, the source weight that shakes of sieve machine is little, and motor power is low, greatly solves the energy consumption problem, adopts four-layer structure, and throughput improves greatly, increases the throughput of unit equipment, and screening efficiency is showing and is promoting.
