Solid Material Feeding Device Slide Mechanism for Clog Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solid material feeding apparatuses face challenges in feeding poorly flowing powders and powders that tend to form clumps or adhere, leading to clogging issues within the conveying connection between the funnel and the solid material outlet.
Innovation Solution
A solid material feeding apparatus equipped with a slide that can be moved through the conveying connection between two end positions, activated to clear clogs and detach adhesions within the conveying connection, ensuring smooth feeding of solid materials to a mixing apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pneumatic knockers or vibrators are used to release adhesions in the funnel region, then adhesions and clogging in the funnel can be largely avoided, but the conveying connection downstream of the funnel is not included by the vibrations and shocks, so feeding through the conveying connection remains problematic
Solution Approach 1:
The patent combines the funnel and conveying connection into a single integrated unit that can be uniformly treated by the knocker or vibrator. The conveying connection is designed as part of the funnel assembly, allowing vibrations and shocks to propagate throughout the entire solid material passage, including previously inaccessible regions downstream of the funnel.
Solution Approach 2:
The patent applies mechanical vibrations through pneumatic knockers or vibrators to the funnel and conveying connection to prevent and remove adhesions. The vibrations create shocks that detach adhering solid material from the inner surfaces of the conveying connection, ensuring continuous feeding without clogging.
2Reliability
If a slide is added to clear clogs in the conveying connection, then feeding reliability improves, but the device complexity increases
Solution Approach 1:
The slide is designed to be automatically actuated by the existing vibration mechanism or pressure differential in the system. When clogging occurs, the vibration or pressure change triggers the slide to move and clear the blockage without requiring external control systems or additional actuators, allowing the system to clear its own obstructions.
Solution Approach 2:
The slide is designed as a simple, extractable component that can be easily removed and cleaned if needed. The slide mechanism is integrated into the conveying connection but can be accessed and maintained without dismantling the entire feeding apparatus, simplifying maintenance while providing reliable clog clearance.

AI summary
The invention relates to improvements in the technical field of feeding solid materials to mixing devices. For this purpose, the solid-material feeding device, inter alia, is proposed. The solid-material feeding device comprises the slide, which can be moved between a first end position and a second end position through a conveying connection, which is arranged between a funnel and a solid-material outlet of the solid-material feeding device. By means of the slide, adhesions within the conveying connection can be loosened without having to remove the conveying connection.
