Axial principle and structure of drilling fluid shaker

Release time: 2015/10/26 Ai Yi NewsViews : 1355

There are many types of drilling fluid vibrating screens, with different uses. From the perspective of Xiaotong, there are many classification methods for drilling fluid vibrating screens. Among them, according to the motion trajectory of the vibrating body of the screening machine, that is, the screening box, the drilling fluid vibrating screen can be roughly divided. The circular drilling fluid vibrating screen, the linear drilling fluid vibrating screen, the rotary vibrating screen, and the elliptical drilling fluid vibrating screen which are evolved from the combination of the circular vibrating screen and the linear drilling fluid vibrating screen.
Drilling fluid vibrating screen generally consists of vibrator, box, vibration isolation device and transmission device. Various drilling fluid vibrating screens have a rectangular screen surface. The screen surface is installed in the screen box in a certain way. The screen box and the screen surface perform a reciprocating movement with a specific trajectory under the action of a vibrator. The continuous vibration of the screen surface makes the screen Noodles. Circular vibrating screen refers to the vibrating body of the screening machine, that is, the inertial drilling fluid vibrating screen with a circular motion trajectory. This drilling fluid vibrating screen is also called a uniaxial drilling fluid vibrating screen. Circular drilling fluid vibrating screen is a type of screening equipment with many specifications and wide application. The screen surface of various circular drilling fluid vibrating screens usually has single-layer and double-layer structures. It is widely used in coal, Dry, wet classification of various granular and small bulk loose solid materials in mining, power, building materials, light industry and chemical industries. From the perspective of the structure of the screen shaker, the circular drilling fluid vibrating screen has two types: the eccentric shaft YA series and the block eccentric YK series. The YA series shaft eccentric circular vibration screen has high screening efficiency and structure. Scientific and reasonable, the whole machine has high strength and rigidity, stable operation, low noise, and convenient maintenance.
The circular vibrating screen is also called a uniaxial drilling fluid vibrating screen. The vibration force generated by the vibrating source of the circular drilling fluid vibrating screen is an inertial force that changes around the fixed axis in a positive regular direction. Its essence is formed by the eccentric mass rotating around the fixed axis. Centrifugal force. The working principle of the circular drilling fluid vibrating screen is that after the sieve is started, the sieve shaker drives the drilling fluid vibrating sieve box to perform a directional jumping movement. Meanwhile, the material smaller than the sieve surface diameter falls through the sieve hole to the lower layer and becomes the sieve The material, which is larger than the sieve surface diameter, is discharged from the discharge port after continuous jumping. The screening work is finally completed. According to the structural characteristics and working principle of the circular vibrating screen, the screen surface is generally inclined (the inclination angle is 15-25 degrees).
From the structure and working principle of the circular vibrating screen, it can be seen that the rotating direction of the exciter is two cases of rotating in the direction of the material flow and the direction of the flow in the opposite direction to the direction of the material flow. Obviously, when the shaker turns in the downstream direction, the material running speed increases, which can increase the production capacity, but the screening efficiency decreases; when the shaker turns in the reverse direction, the material running speed decreases, the production capacity decreases, but the screening to raise efficiency. In view of this, in the actual screening operation, we can make a choice between the production capacity and the screening efficiency according to specific questions and needs.
