Abstract
The utility model discloses a prestress vibrating screen which is composed of a wire mesh (3) and a frame (1), wherein, the frame is manufactured by the angle steel and is composed of an upper part and a lower part. Four edges of the metal screen are strained and installed between an upper frame and a lower frame. The four edges of the metal screen is fixed and positioned by a rivet (2) to make the warp direction and the weft direction of the screen obtain the homogeneous strain. A canvas rubber pad is arranged between the frames and the metal mesh. The utility model can make the screen obtain the homogeneous force to reduce the secondary vibration, so that the service life of the screen is prolonged and the filter precision of the screen is improved.
Description
The utility model has related to the petroleum machinery annex, and a kind of screen cloth of mud vibrating screen is applicable to vibration filtering mud in the oil drilling specifically, also can use the occasion of vibratory sieve in order to other.
Existing Shale Shaker Screens is one and is in the woven wire that is not subjected to tensile force under the free state, is surrounded by a strip metal boundary belt at two ends, and the operator strains the two ends of screen cloth and be fixed on the support underframe of vibratory sieve with hook plate or roller bar during use.This screen cloth is subjected to artificial factor owing to only be subjected to the pulling force of the left and right sides and the rate of tension of screen cloth in the horizontal direction, and in use the screen cloth discontinuity easily produces self-excited oscillation (secondary vibration) and alternate stress, has influenced the service life of screen cloth.
It is stressed evenly that the purpose of this utility model is to release a kind of metal twine, and what be not subjected to that the operator influences gives the stress vibration screen, with service life of prolonging screen cloth with improve filtering accuracy.
Design of the present utility model is before last vibratory sieve is installed, and just allows screen cloth be in the tension stress, and the screen cloth that is easy to do like this is stressed even and easy for installation.
Task of the present utility model is by realizing the woven wire clamping on a framework.Framework is made up of the steelframe of two squares up and down, it is fixed that size is come by the specification of screen cloth, square steelframe can be welded with angle steel, also available slot shaped steel etc. is easy to accomplish that the special-shaped steel part that clamps screen cloth makes, four periphery tension back clampings of woven wire are between two steelframes, with rivet it is tightened fixingly, make screen cloth before online, be subjected to uniform pulling force in the horizontal direction.When last vibratory sieve is installed, only need screen cloth to be pressed on the bracing frame of vibratory sieve and get final product with a simple hold-down mechanism, needn't by operating personnel again row install with hook plate etc. and strain screen cloth.
Great advantage of the present utility model is to have overcome the secondary vibration of screen cloth because the vertical and horizontal of screen cloth can both be subjected to uniform pulling force, has guaranteed the service life of screen cloth, and simplifies and made things convenient for installing and using of vibratory sieve.
Concrete structure of the present utility model is provided by following accompanying drawing:
Fig. 1 is the structural representation of the vibration screen manufactured according to the utility model.
As figure, (1) for going out husky plate, (2) be upper frame, (3) be rivet, (4) be woven wire, (5) be last liner, (6) be lower liner, (7) be underframe, (8) be veil, (9) be the lining net, woven wire (4) by veil (8) and lining net (9) up and down two parts forms, veil is 40 to 80 purpose woven wires, serving as a contrast net is 12 to 20 purpose woven wires, upper frame (2) and underframe (7) square steelframe for making with the angle steel weldering, be fixedly connected with one on the upper frame and go out husky plate (1), from the longitude and latitude both direction with screen cloth (4) tension back four peripheral clampings of screen cloth up and down between the framework, about be lined with the liner of manufacturing with the wear-resisting ageing-resistant flexible material of canvas or rubber and so on (5) between framework and the screen cloth, (6), preventing the wearing and tearing of steelframe to screen cloth, with rivet (3) along the periphery of framework with the screen cloth location of riveting tightly.During use, directly be contained on the vibratory sieve, with a lever hold down gag screen cloth be pressed on the bracing frame of vibratory sieve and get final product tightening stressed screen cloth.The screen cloth of manufacturing according to present embodiment can improve 1.5 to 2 times than the life-span of common screen cloth.
Claims (2)
1, a kind of vibrating screen mesh of manufacturing with woven wire, woven wire (4) is made up of veil (8) and two-layer the stacking togather of lining net (9), it is characterized in that this screen cloth also includes a framework, framework is by two square steelframes (2) and (7) are formed up and down, four periphery tension clampings of woven wire (4) are up and down between the framework, tighten the location with rivet (3), between framework and woven wire, be lined with canvas or rubber packing (5) and (6).
2, screen cloth as claimed in claim 1 is characterized in that framework makes with angle steel, and also available channel-section steel or other are easy to realize that the special-shaped steel part of straining screen cloth makes.
