Flexible Lining Sock for Foundry Chute Gas Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies fail to effectively protect the interior and exterior surfaces of chutes and surrounding areas from premature hardening of workable foundry molding mix due to exposure to hardening gases in the cold box process of metal casting, leading to cleaning challenges.
Innovation Solution
A flexible liner with an upper border portion for securing to the chute and a body portion made of flexible material, such as woven polymeric fibers coated with a polymeric coating, is designed to line the interior surface of the chute, featuring apertures with reinforcing grommets for attachment and easy cleaning, and extending beyond the chute edge for easy removal and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a flexible liner is installed to protect the chute interior surface from premature hardening, then protection from hardening gas is improved, but device complexity increases
Solution Approach 1:
The patent applies a flexible liner made of thin film material to line the interior surface of the chute. This flexible shell approach provides effective protection from hardening gas contact while maintaining simplicity in installation and removal, directly resolving the contradiction between protection effectiveness and device complexity
Solution Approach 2:
The flexible liner acts as an intermediary barrier between the workable foundry molding mix and the hardening gas environment. This mediator prevents direct contact between the harmful gas and the mix, providing protection without requiring complex sealing systems or permanent installations
2Ease of operation
If the liner extends beyond the chute edge for easy removal and cleaning, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The liner is designed with an extension that protrudes beyond the chute edge before use. This preliminary configuration of the extension allows operators to easily grasp and remove the liner for cleaning without requiring complex removal mechanisms, thereby improving ease of operation while adding minimal structural complexity

AI summary
A liner protects an interior surface of a chute that transfers workable foundry molding mix from a mixer to a machine for molding and hardening. The liner has an upper border portion and body portion. The upper border portion secures the liner to an upper portion of the chute. The body portion has at least one panel of a flexible material and is sized and adapted to line the interior surface of the chute. The liner also has a plurality of apertures through the upper border portion for attaching the upper border portion to the upper portion of the chute. The flexible material of the body portion is a woven fabric with polymeric fibers and, optionally, a polymeric coating.
