Abstract
The utility model relates to a biaxial linear vibrating screen which solves the problems that the work efficiency of the existing vibrating screen is low, a screen mesh is easy to loose and the screen mesh is easy to damage and has short service life. The utility model is characterized in that two exciting motors (4) of which the rotary directions are opposite are fixed on the screen body (1), the screen mesh (2) forms a circular arc shape, and the underside thereof is provided with a screen lining (5) of which the bottom part is bonded with a rubber layer (6); the screen mesh (2) is fixed on the side wall of the screen body (1) through a tensioning device (7). The screen mesh of the biaxial linear vibrating screen carries out straight reciprocating motion. The utility model has the characteristics that the work efficiency is high, the tensile force of the screen mesh can be automatically adjusted and the service life of the screen mesh is long.
Description
Technical field:
The utility model relates to drilling fluid filter in the petroleum drilling and mining process, especially twin shaft linear vibrating screen.
Background technology:
In the petroleum drilling and mining process, drilling fluid recycles, and will damage drill bit or pump as containing the bulky grain drilling cuttings in the drilling fluid that the down-hole is returned up, must could use through filtering, and utilizes vibratory sieve that drilling fluid is filtered usually.The vibrating screen mesh that uses can not be regulated at present, and screen cloth is easily loosening, and changing or regulate screen cloth wastes time and energy; In addition, this vibratory sieve is to utilize a vibrating motor, and screen cloth moves on elliptical path, and screen cloth and bracing frame produce collision and friction, makes that screen cloth is fragile, service life short, and screen cloth is the inefficiency that the plane makes screen cloth.
The utility model content:
In order to overcome the easily loosening and screen cloth short deficiency in fragile service life of existing vibratory sieve inefficiency, screen cloth, the utility model provides a kind of twin shaft linear vibrating screen, the screen cloth of this twin shaft linear vibrating screen is straight reciprocating motion, has high efficiency, screen cloth tension force can be regulated automatically and the characteristics of screen cloth long service life.
Cross on the sidewall that tensioning apparatus is fixed on sieve nest.
Above-mentioned tensioning apparatus comprises bolt, pressing plate and spring, and screen cloth is fixed on the pressing plate, and bolt passes the sidewall of pressing plate and sieve nest, and spring is fixed on by pad and nut on the bolt in the sidewall outside of sieve nest.
The utlity model has following beneficial effect: owing to take to be fixed with two shock electric machines that direction of rotation is opposite on the sieve nest in the such scheme, can make sieve nest only do straight-line oscillation, avoid screen cloth bump and friction support frame and damage; Screen cloth is circular-arc, effectively in the filter area that has increased drilling fluid, has improved high efficiency, is equipped with the sieve lining that the bottom is stained with rubber layer below the screen cloth, has increased intensity, rigidity and the wearability of screen cloth, has prolonged the service life of screen cloth; Screen cloth is fixed on by tensioning apparatus on the sidewall of sieve nest, and tensioning apparatus can be regulated the tension force of screen cloth automatically.
Description of drawings:
Accompanying drawing 1 is a structure cutaway view of the present utility model.
1-sieve nest among the figure, the 2-screen cloth, the 3-spring(-supported) mount, the 4-shock electric machine, 5-sieves lining, 6-rubber layer, 7-tensioning apparatus, 8-bolt, 9-pressing plate, 10-spring, 11-pad, 12-nut, 13-bracing frame.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this twin shaft linear vibrating screen comprises sieve nest 1, screen cloth 2 and spring(-supported) mount 3, sieve nest 1 is connected on the spring(-supported) mount 3, be fixed with two shock electric machines 4 that direction of rotation is opposite on the sieve nest 1, two eccentric blocks that quality equates in two motors 4 rotate synchronously, the centrifugal force direction that produces during work is opposite, wherein the vibration component that produces in the horizontal direction is superimposed, and it is opposite in the vibration force direction of vertical direction, cancel out each other, can make 1 of sieve nest do straight-line oscillation, avoid screen cloth 2 bump and friction support frame 13 and damage; Screen cloth 2 is circular-arc and is equipped with the sieve lining 5 that the bottom is stained with rubber layer 6 below it, has increased intensity, rigidity and the wearability of screen cloth 2, has prolonged the service life of screen cloth 2; Screen cloth 2 is fixed on the sidewall of sieve nest 1 by tensioning apparatus 7; Tensioning apparatus 7 comprises bolt 8, pressing plate 9 and spring 10, screen cloth 2 is fixed on the pressing plate 9, bolt 8 passes the sidewall of pressing plate 9 and sieve nest 1, and spring 10 is fixed on by pad 11 and nut 12 on the bolt 8 in the sidewall outside of sieve nest 1, can regulate the tension force of screen cloth under the effect of spring 10 automatically.
