Movable Heat Shield Assembly for Hot Blast Stove Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat shield assemblies for hot blast stoves are difficult to deploy efficiently in high-temperature environments, hindering effective maintenance and safety in hot blast stove installations.
Innovation Solution
A heat shield assembly with a main body and movable shield parts that transition from a compact position to a deployed position along a plane, allowing for easy insertion and expansion to cover the cross-sectional area of the burner shaft, with the shield parts extending to form a continuous heat shielding surface without gaps, and optionally featuring a heat-resistant layer or lining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heat shield assembly is designed with a large surface area to cover the burner shaft cross section, then the heat shielding effectiveness is improved, but the difficulty of insertion and deployment increases
Solution Approach 1:
The heat shield assembly is divided into a main body and multiple separate shield parts that can be independently positioned. This segmentation allows the components to be inserted through the hot blast outlet opening separately and then assembled to form the complete shielding surface, making deployment feasible in the confined space
Solution Approach 2:
The shield parts are designed to be movable relative to the main body, transitioning from a compact configuration during insertion to an extended configuration for shielding. This dynamic capability allows the assembly to adapt its form factor based on operational requirements
2Reliability
If the shield parts are arranged to extend from the main body to form a complete shielding surface, then the heat shielding coverage is improved, but the compactness for storage and transport deteriorates
Solution Approach 1:
The shield parts are designed to be contained within or overlap with the main body when not in use, creating a nested configuration. This allows the complete shielding assembly to be stored in a compact form factor while maintaining the capability to extend to full shielding coverage during operation
3Ease of operation
If the shield parts are made movable to enable deployment, then the ease of installation is improved, but the structural complexity increases
Solution Approach 1:
The movable shield parts are designed as separate, discrete components with simple connection interfaces to the main body. This segmentation allows each part to move independently with minimal mechanical complexity while achieving the desired deployment capability
