Sloped Screen Assembly for Shaker Fluid Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaker systems struggle to efficiently separate drilling fluid from cuttings while accommodating large fluid volumes and require complex installation and removal of multiple screens with staggered sloped surfaces.
Innovation Solution
A screen assembly with sloped support members and screen filters that form a staggered sloped screen surface, allowing multiple screens to be coupled together and easily installed or removed from the shaker system, enhancing fluid holding capacity and separation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple screens with staggered sloped surfaces are used to increase fluid holding capacity and separation efficiency, then the shaker system can handle larger fluid volumes and improve separation performance, but the installation and removal of screens becomes more complex and time-consuming
Solution Approach 1:
The screen assembly is divided into multiple individual screens that can be independently installed and removed. Each screen is a separate module with its own frame and filtering surface, allowing operators to work with one screen at a time rather than handling a complex integrated structure. This segmentation enables easier maintenance while maintaining the staggered sloped configuration for optimal fluid handling.
Solution Approach 2:
The screen assembly incorporates adjustable and movable components that allow for dynamic configuration during installation and operation. The screens can be positioned and secured in a staggered sloped arrangement that optimizes fluid flow, yet can be easily reconfigured or removed when needed. This dynamic design balances the need for complex separation surfaces with operational simplicity.
2Productivity
If screens are designed with staggered sloped surfaces to optimize fluid flow and separation, then separation efficiency improves, but the structural complexity and manufacturing difficulty increase
Solution Approach 1:
The complex staggered sloped surface is segmented into multiple discrete screen modules, each with a simpler individual structure. Rather than manufacturing one complex integrated screen assembly, the system uses multiple standardized modules that can be independently manufactured and then assembled into the staggered configuration. This reduces manufacturing complexity while achieving the desired fluid flow optimization.
Solution Approach 2:
The screen modules are designed with universal features and standardized interfaces that allow them to function in multiple positions within the staggered arrangement. Each screen module can serve the same separation function regardless of its specific position in the assembly, simplifying manufacturing by using identical or similar components throughout the system rather than custom-designed pieces.

AI summary
A screen assembly includes a screen with a screen frame and a screen filter. The screen frame includes a leading edge with a first height and a trailing edge with a second height. The screen filter extends between the leading edge and the trailing edge to provide a sloped screen surface. The screen assembly may also include an additional screen with an additional screen frame and an additional screen filter. The additional screen frame includes an additional leading edge with a respective first height and an additional trailing edge with a respective second height. The additional screen filter extends between the additional leading edge and the additional trailing edge to provide an additional sloped screen surface. The additional screen is configured to couple to the screen such that the additional sloped screen surface and the sloped screen surface form a staggered sloped screen surface.
