Abstract
The utility model relates to a multi-axis elliptic vibration screen with self-synchronizing translation. A vibration exciter is a vibration exciter group which is composed of more than two excitation axes with unequal eccentric quality and motors with the corresponding quantity of the excitation axes. The motors drive the corresponding excitation axes to rotate in a self-synchronization mode, and a straining box of the vibration screen realizes translational elliptical vibration. A screen mesh on the straining box can adopt a single-layer structure, a double-layer structure or a multilayer structure according to sieving requirements. The vibration screen can provide large exciting force, and can realize sieving with heavy load and large screen surfaces; therefore, the utility model is especially suitable for conditions with large treating capacity, high required sieving efficiency and good sieving effect. The utility model can be used for the development engineering of drilling fluid for petroleum and natural gas, and other fields needing sieving material.
Description
The utility model relates to the vibratory sieve that the inertia vibrating screen that is used to sieve material particularly sieves oil, gas drilling liquid.
At present domestic and international employed all kinds of inertia vibrating screens normally are made up of screen box, base, screen cloth and vibrator, and vibrator comprises motor and eccentric massblock.Motor output shaft drives the eccentric massblock rotation and produces a centrifugal intertia force (exciting force), thereby makes the motion of vibratory sieve screen box; When " centre of force " of centrifugal intertia force overlaps with the barycenter of vibratory sieve screen box integral body, vibratory sieve screen box integral body is made translational motion, all the movement locus with barycenter is identical for the movement locus of each point on the screen box, and the movement locus of barycenter (that is " vibration shape ") depends on the Changing Pattern of exciting force fully.The vibrator that adopts in producing at present has two kinds of single shaft and twin shafts.The single shaft inertia shaker vibrator, because the size of the centrifugal inertial force of its generation is constant all the time in rotary course, thereby the movement locus of each point can only be " circle " on the screen box, the screening efficiency and the transporting velocity of this " circle " vibration shape vibratory sieve are all lower, often do not satisfy the needs of screening and transportation work.Therefore, in 93239430.2 patents, the eccentric massblock that is arranged on the motor output shaft in the existing single shaft inertia shaker vibrator is replaced by the single file star-wheel internal-gearing planet gear mechanism that has eccentric massblock, make vibratory sieve except that doing " circle ", the vibration of " straight line " vibration shape, realized that also work " ellipse " vibration shape vibrates.This single-shaft vibrating screen is simple in structure, the screening efficiency height, but owing to being subjected to bigger concentrfated load to make its life-span be subjected to bigger influence on the bearing, thereby do not apply aborning as yet at present.Double shaft inertia shaker as for using in producing at present normally adopts two shock electric machines that have identical eccentric mass, and the inertial excitation power of its generation makes vibratory sieve do the vibration of " straight line " type.There is the throwing dead band in " straight line " though vibration shape vibratory sieve has higher solid phase transporting velocity, is difficult to dish out from sieve aperture for the solid phase particles of plug in sieve aperture, easily stops up sieve aperture (promptly producing " screen blinding " phenomenon).Therefore in 99232313.4 patents, proposed to have the unequal two eccentric shafts rotation of eccentric mass by the transmission mechanism drive, it has been forced synchronously, so that vibratory sieve is realized the balanced elliptic vibration with a shock electric machine.The screening of this vibratory sieve and transfer efficiency are all high, but the middle transmission mechanism transferring power that adopts has increased manufacturing and maintenance cost.On the other hand, as can be known, the exciting force and the screen area of present employed single shaft or dual-axis vibration sieve are all limited, often do not satisfy the requirement of high throughput from produce reality.
The purpose of this utility model is, proposes a kind of big exciting force, big sieving area, screening and transfer efficiency is all higher, and drilling fluid vibrating sieve simple in structure, that can realize not having the running safeguarded.
For achieving the above object, the utility model by the following technical solutions:
Vibratory sieve mainly is made up of base (1), screen box (2), screen cloth (4) and vibrator, screen cloth (4) is installed on the screen box (2), screen box (2) connects with base (1) by elastic support (5), it is characterized in that: the vibrator group that vibrator is made up of unequal vibrating shaft of eccentric mass (6) such as (as: two, three, four) and motor (3) corresponding with vibrating shaft (6), equivalent amount more than two, the quantity of vibrating shaft (6) and the big I of eccentric mass thereof increase, subtract according to the needs of reality to exciting force; Vibrating shaft (6) is installed on the appropriate location of screen box (2), and " centre of force " that its installation site should be able to make exciting make a concerted effort overlaps with the barycenter of screen box integral body; Motor (3) is installed on the screen box (2) or on the base (1), achieves stepless speed regulation by frequency converter (7).During work, motor (3) is by belt wheel or drive corresponding vibrating shaft (6) by belt wheel and Hooks coupling universal coupling and make rotation self-synchronization, the making a concerted effort of its exciting force by oval cyclically-varying, thus make vibratory sieve do the balanced elliptic vibration.
Motor (3) can adopt common fire-proof motor or antivibration fire-proof motor.
The screen cloth of vibratory sieve (4) can adopt individual layer, bilayer or sandwich construction, and bilayer or multilayer web frame can improve the screening efficiency of vibratory sieve and obtain screening effect preferably.
The utility model has the advantages that: (1) adopts many vibrating shafts, and bigger exciting force can be provided, thereby can realize that heavy duty, big compass screen surface sieve, thereby improved treating capacity.(2) do not have transmission mechanisms such as gear, synchronous band between each vibrating shaft, Structure of Vibrating Screen is simplified, and can be realized not having the running of maintenance, the while has also reduced the pollution to environment.(3) adopt common fire-proof motor or antivibration fire-proof motor, low than the cost of shock electric machine, and the shaft strength condition of vibrating shaft improves, thus its life-span is improved by a relatively large margin.(4) vibrating screen mesh adopts bilayer or sandwich construction, has further improved screening efficiency and can obtain screening effect preferably.
