Problems solved by technology

In many environments in which vibratory separators and shale shakers are used, these steel parts are subjected to harsh conditions that result in wear, erosion, rust, and corrosion of the steel.
Both the salt environment and the chemicals in drilling fluids processed by the shale shakers can contribute to the d...

Embodiment Construction

[0033] FIGS. 1-3 show a shale shaker 10 according to the present invention which has a screen-mounting basket 12 and a bridge 14 on which are mounted two vibrating apparatuses 20. The basket 12 has brackets 16 to which are secured helical springs 18. Each spring 18 is secured to a base member 22. As shown in FIG. 3, an optional housing 24 may be used on sides of and beneath the shale shaker 10. Optionally (and as may be the case with any shale shaker disclosed herein according to the present invention or with any known prior art shaker or vibratory separator) an electronic tracking apparatus 29 is on the housing 24, but may, according to the present invention, be within any suitable member or part of a shale shaker; and, optionally, such a tracking apparatus has a container or housing made of composite material and / or is encased within or coated with composite material. Any known tracking device, apparatus, or system may be used, including, but not limited to known satellite trackin...

Abstract

A shale shaker or vibratory separator which, in one aspect, has a base, vibration isolation apparatus on the base, a basket, mount apparatus for mounting the basket on the base, and at least one of the base, basket, and the mount apparatus made of, encased in, or coated with composite material which, in certain aspects, is all or part flexible composite material; and methods of using such separators and shakers.

Description

[0001] 1. Field of the Invention[0002] This invention is directed to vibratory separators and, in certain particular aspects, to shale shakers and to shale shakers with structural members made of composite material.[0003] 2. Description of Related Art[0004] Many typical vibratory separators and shale shakers have a container, carrier, housing, or basket to which is secured one or more screens used for separating components of material fed to the vibratory separator or shale shaker. Vibrating apparatus connected to the container, etc. vibrates the container, etc. and the vibrations are imparted to the screen or screens secured to the container, etc.[0005] Typically it is desirable to maximize vibration of the screen(s) while isolating equipment, objects, and structures adjacent the vibratory separator from the intense vibrations produced by the vibrating apparatus. Such isolation is effected by using springs, rubber or rubber-like or resilient members or cushions, isolator apparatus,...
