Conventional paper pulp screens are heavy, require complex installations, costly, and result in high maintenance and operational costs, leading to increased downtime and reduced production.
Innovation Solution
A lightweight, easily installable paper pulp pressure screen design that can be retrofitted inline with existing piping, featuring a casing with a diagonal leg member, a basket for filtering, and a rotor mechanism to maintain flow, with options for continuous or intermittent drain outlets for contaminants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional paper pulp screens are used, then screening function is provided, but weight and installation complexity increase
Solution Approach 1:
The screen is divided into separate modular components including a screen body, basket assembly, motor assembly, and drive mechanism. These modules can be manufactured independently and assembled together, reducing overall weight while maintaining structural integrity and screening functionality.
Solution Approach 2:
The screen body is designed with a standardized configuration that can accommodate different basket sizes and motor assemblies, allowing a single basic structure to serve multiple screening applications. This universal design reduces the need for heavy custom-built screens for each specific application.
2Reliability
If conventional paper pulp screens are used, then screening function is provided, but installation complexity and cost increase
Solution Approach 1:
By segmenting the screen into standardized modules with clear interfaces, the installation process becomes more systematic and less complex. Each module can be installed independently and connected through standardized mounting mechanisms, reducing installation complexity.
Solution Approach 2:
The motor assembly and drive mechanism are integrated into a unified motor assembly that combines multiple functions (motor, gearbox, drive shaft) into a single compact unit. This merging reduces the number of separate components that need to be installed and aligned, simplifying the overall installation process.
3Reliability
If conventional paper pulp screens are used, then screening function is provided, but maintenance cost and downtime increase
Solution Approach 1:
The modular design allows the basket, filtering media, and motor assembly to be independently removed and replaced. When maintenance is needed, only the affected module needs to be accessed and replaced, not the entire screen system, significantly reducing maintenance time and cost.
Solution Approach 2:
The basket and filtering media are designed as easily extractable components that can be removed from the screen body without disassembling the entire system. This extraction capability allows for quick media replacement and basket cleaning, reducing maintenance downtime.
4Reliability
If conventional paper pulp screens are used, then screening function is provided, but operational cost increases
Solution Approach 1:
The rotor design creates a self-cleaning action that prevents contaminant buildup on the filtering media. By using the flow of pulp slurry itself to rotate the rotor and scour the media, the system eliminates the need for additional energy-consuming cleaning mechanisms while maintaining screening efficiency.

AI summary
A paper pulp pressure apparatus includes a body casing having a pipe member and a leg member. The leg member extends diagonally from the pipe member. The pipe member includes an input end for receiving unfiltered fluid and an output end for outputting filtered fluid. The leg member includes a basket for receiving the unfiltered fluid from the input end. The basket includes a cavity which receives a rotor. The leg member includes a drain outlet which is in fluid communication with the cavity of the basket so as to receive contaminants from the unfiltered fluid unable to pass through a filtering media included in the basket.
