Problems solved by technology

[0002] Drilling fluid shale shaker is the first-level basic solid phase control equipment for drilling fluid returned to the wellhead. It not only has to undertake the task of removing a large amount of large particle cuttings, but most of the domestic screening effects are poor, easy to dry, sieve paste, and sieve incompletely. , The phenomenon of mud running has caused great troubles to production. Although the screening effect of foreign vibrating screens is very good, the cost is extremely expensive. Once damaged, the replacement of parts will also require a huge cost

Abstract

The invention discloses a vibrating screen, relates to a separating device, and particularly relates to a vibrating screen for separating an oil well fluid. The vibrating screen disclosed by the invention comprises a tube connector, a buffering box, a screening box, an exciter and a base, wherein the tube connector, the buffering box and the screening box are sequentially connected; the exciter is arranged on the upper part of the screening box; the base is arranged on the lower part of the screening box; an elastic material is arranged between the screening box and the vibrating screen; and the exciter is elliptical. The vibrating screen disclosed by the invention is used for screening rock debris in the oil fluid via the vibration of the elliptical exciter, and elliptical vibration is good in screening effect and high in treatment capacity because of having the characteristics of both circular vibration and linear rectilinear vibration; and the vibrating screen disclosed by the invention is simple in structure and strong in practicability.

Description

technical field [0001] The invention relates to a separation device, especially a vibrating screen used for the separation of oil well liquid. Background technique [0002] Drilling fluid shale shaker is the first-level basic solid phase control equipment for drilling fluid returned to the wellhead. It not only has to undertake the task of removing a large amount of large particle cuttings, but most of the domestic screening effects are poor, easy to dry, sieve paste, and sieve incompletely. , The phenomenon of mud running has caused great troubles to production. Although the screening effect of foreign vibrating screens is very good, the cost is extremely expensive. Once damaged, the replacement of parts will also require a huge cost. Contents of the invention [0003] The invention aims to provide a vibrating screen with simple structure and good screening effect. [0004] A vibrating screen according to the present invention includes a pipe interface, a buffer box, a s...
