Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wood particle wetting devices face issues with wood particles adhering to the inner system parts, leading to expensive downtimes and complex maintenance due to excessive gluing, which increases the risk of packing.
Innovation Solution
A device with a chute allowing wood particles to fall freely, featuring nozzles arranged on a protruding component that is spaced from the chute's inner walls, with a spray direction parallel to the chute and a fanned-out spray pattern to minimize contact with the walls, reducing accumulation and facilitating easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If nozzles are arranged on the inner walls of the chute for spraying medium onto wood particles, then the wetting effect is improved, but wood particles adhere to the inner walls forming packs that require regular removal and cause downtime
Solution Approach 1:
The nozzles are mounted on a component that protrudes into the chute interior from the outer wall, changing the spatial arrangement from a two-dimensional wall-mounted configuration to a three-dimensional extended configuration. This positioning allows nozzles to spray onto particles in free fall without contact with inner walls, eliminating packing while maintaining wetting effectiveness.
2Quantity of substance
If spray pressure is increased to improve wetting coverage, then the binder is sprayed more effectively onto wood particles, but accumulation on inner walls increases and maintenance complexity increases
Solution Approach 1:
The nozzles are extracted from the inner wall surface and repositioned on a protruding component that extends into the chute. This extraction removes the source of packing (nozzle-to-wall contact) while preserving the spraying function, allowing effective binder distribution without the harmful side effect of accumulation on inner walls.
3Use of energy by moving object
If nozzles are positioned close to the inner walls to reduce spray pressure requirements, then energy consumption is reduced, but the risk of wood particle accumulation on walls increases
Solution Approach 1:
The protruding component acts as an intermediary structure that positions nozzles close to the particle flow path without direct contact with inner walls. This mediator enables low-pressure spraying (reducing energy consumption) while preventing the harmful effect of particle accumulation on walls by eliminating the wall contact interface.
