Screen assembly for vibratory separators

A shale shaker system for separating components of drilling fluid with solids entrained therein, the shale shaker system, in at least certain aspects, including a base, a screen mounting basket on the base, vibrating apparatus connected to the screen mounting basket for vibrating the screen mounting basket, the screen mounting basket having mounting structure for at least one screen assembly mounted on the mounting structure, the mounting structure having a body over which the at least one screen assembly is positionable, some components of the drilling fluid to be treated by the shale shaker flowable through the at least one screen assembly and through the body, at least one wear strip attached to the mounting structure, the at least one wear strip having a wear strip body, at least one upwardly projecting member projecting upwardly from the wear strip body, the at least one screen assembly including a screen support with screening material and at least one hole in the support sized, configured, and located for receiving the at least one upwardly projecting member of the wear strip body of the mounting structure and the at least one upwardly projecting member sized, located and configured for receipt within the at least one hole.

Screen assemblies for shale shakers

Screens and screen assemblies for a vibratory separator or shale shaker, such screens and screen assemblies made by a method including applying glue in a glue pattern to at least one layer of screening material, said applying done by powered moving mechanical glue application apparatus; in one aspect moving with powered mechanical screen movement apparatus the at least one layer of screening material beneath the powered moving mechanical glue application apparatus; in one aspect, using hot melt moisture-curing glue, and in one aspect facilitating the cure of moisture-curing glue by applying moisture to it.

Glued screens for shale shakers

A vibratory separator for separating components of material introduced to the vibratory separator, the vibratory separator in one particular aspect being a shale shaker, the vibratory separator including a basket for holding screening apparatus, the basket having two sides spaced-apart by a first end at which the material is introduced into the basket and a second end spaced-apart from the first end, components separated from the material exiting the basket from the second end, vibrating apparatus connected to the basket for vibrating the basket, screening apparatus mounted in the basket, the screening apparatus having at least a first portion and a second portion, the first portion at the first end of the screen and the first portion lower in the basket than the second portion, receptacle apparatus below the screening apparatus for receiving material components flowing through the screening apparatus, maintenance apparatus for maintaining height of a portion of the screening apparatus, and a pool of the material formable above the first portion of the screening apparatus.

Vibratory separator

Methods for making screen assemblies and screens for a vibratory separator or shale shaker, such methods including applying glue in a glue pattern to at least one layer of screening material, said applying done by powered moving mechanical glue application apparatus; in one aspect moving with powered mechanical screen movement apparatus the at least one layer of screening material beneath the powered moving mechanical glue application apparatus; in one aspect, using hot melt moisture-curing glue, and in one aspect facilitating the cure of moisture-curing glue by applying moisture to it.

Methods for making glued shale shaker screens

A screen assembly for a vibratory separator, the screen assembly having a first screen portion having a first end and a second end spaced apart from the first end, and a second screen portion formed integrally of or connected to the second end of the second screen portion. A screen assembly with a first portion of screening material and a second raised portion of screening material, the second raised portion extending from a material introduction end of the screen assembly to a material exit end thereof, the raised portion, in one aspect, culminating in an apex above the first portion of screening material.

A method for making a screen assembly for a vibratory separator, which, in certain aspects, includes placing a first layer of screening material below a glue application apparatus, and applying with the glue apparatus an amount of glue in a pattern to a portion of the first layer of screening material, unrolling part of a second layer from a second roll and positioning the part of the second layer adjacent part of the first layer to which glue has been applied, moving the part of the second layer and the part of the first layer between opposed rotatable spaced-apart rollers to press together the part of the second layer and the part of the first layer to form a pressed-together layer of first and second layers of screening material. In certain aspects hot glue is used and is cooled following application of the second layer on the first layer.

Method for making vibratory separator screens
