Solution Overview
Problem
Current methods for transporting and loading catalyst into chemical reactor tubes are labor-intensive, inefficient, and prone to catalyst breakage and dust generation, which affects reactor performance and worker safety, and are limited by weather conditions and crane availability.
Innovation Solution
A vacuum-packed catalyst transport system using an elongated belt with sprocket-driven sprocket assemblies and a vacuum box to minimize manual handling, prevent catalyst breakage, and reduce dust exposure, allowing for efficient and controlled loading of catalyst into reactor tubes, even in inclement weather.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If catalyst is transported using conventional methods (forklift, crane, hand truck), then catalyst can be moved to reactor vessel, but labor requirements are very high and catalyst breakage increases
Solution Approach 1:
The patent replaces manual mechanical handling (forklift, crane, hand truck) with an automated conveyor system that mechanically transports catalyst containers through enclosed pathways, eliminating the need for multiple manual transfer operations and reducing labor requirements while minimizing catalyst breakage through controlled mechanical handling
Solution Approach 2:
The patent segments the catalyst transport process into distinct automated stages: loading containers onto conveyors at ground level, transporting through enclosed pathways, and unloading at reactor level, allowing each stage to be optimized independently and eliminating the need for continuous manual intervention
2Ease of operation
If catalyst is transported manually through multiple transfers, then catalyst can reach reactor tubes, but catalyst breakage and dust generation increase
Solution Approach 1:
The patent introduces enclosed conveyor pathways as intermediary structures that provide protected transport routes between ground level and reactor vessels, preventing catalyst exposure to environment during transfer and minimizing dust generation through sealed containment
Solution Approach 2:
The patent uses flexible enclosed pathways and covering structures that envelop the catalyst transport route, creating a protected environment that prevents catalyst breakage from exposure and minimizes dust generation through continuous enclosure
3Adaptability or versatility
If crane is used to fly catalyst to top deck, then catalyst can be positioned near reactor, but operation is limited by weather conditions
Solution Approach 1:
The patent replaces weather-sensitive crane operations with an enclosed conveyor system that operates independently of weather conditions, providing reliable catalyst transport through protected pathways that shield against rain, wind, and other environmental factors
4Productivity
If multiple personnel are deployed for catalyst handling, then catalyst can be transported and loaded, but labor intensity and safety risks increase
Solution Approach 1:
The patent implements self-service automated handling where the conveyor system automatically transports catalyst containers from loading to unloading without requiring personnel to physically move or transfer the heavy containers, eliminating exposure to pinch points and reducing labor intensity
