Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for cleaning drawer-like cages used for transporting live poultry are inadequate in ensuring complete cleaning, particularly of ventilation openings and interstices, and fail to maintain stable positioning for effective washing, leading to potential contamination risks.
Innovation Solution
A washing device featuring a rotatable drum with a horizontal axis, angularly spaced supports for slidable engagement of cages, and a helical roto-translational motion, combined with spraying means for thorough washing with a heated sodium hydroxide solution, ensuring complete and uniform cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional horizontal or vertical washing systems are used, then the washing process is simple, but complete cleaning of ventilation openings and interstices cannot be ensured
Solution Approach 1:
The invention introduces a rotatable drum with horizontal axis that rotates during the washing process, dynamically changing the angular position of drawer-like cages relative to spraying nozzles. This dynamic rotation enables washing jets to access ventilation openings and interstices from multiple angles, achieving complete cleaning that static horizontal or vertical systems cannot provide.
Solution Approach 2:
The invention transitions from traditional single-dimension washing (horizontal or vertical) to multi-dimensional washing by rotating the drum around a horizontal axis. This adds rotational movement as a new dimension, allowing washing jets to approach cages from various angular positions and thoroughly clean previously inaccessible areas like ventilation openings.
2Productivity
If chain-movement assemblies are used to move cages through washing station, then continuous processing is enabled, but stable positioning for receiving washing jets cannot be maintained
Solution Approach 1:
The invention replaces static chain-movement assemblies with a dynamic rotatable drum system. Cages are held in slots within the rotating drum, which continuously turns to maintain optimal positioning relative to fixed washing nozzles. This dynamic system ensures both continuous processing and stable positioning, as the rotation speed and cage slot positions are coordinated to keep cages in the most suitable predetermined positions for receiving washing jets throughout the washing cycle.
3Manufacturing precision
If multiple washing positions are used to ensure complete cleaning, then cleaning effectiveness improves, but device size and complexity increase
Solution Approach 1:
Instead of expanding the washing station horizontally with multiple fixed washing positions, the invention utilizes the rotational dimension of a drum with horizontal axis. A single rotating drum provides multiple washing positions through its rotation, allowing cages to be washed from various angular positions without increasing the footprint area of the washing station.
Solution Approach 2:
The rotatable drum serves multiple functions simultaneously: it holds multiple cages in slots, rotates to position cages for washing, and maintains continuous movement for throughput. This multi-functional design achieves complete cleaning effectiveness without requiring separate dedicated washing stations for each position, thereby reducing overall device size.

Implementation Method 1
The washing liquid may consist of a mixture of sodium hydroxide and water, heated to a temperature of about 90° C., with the object of chemically eliminating organic substances removed from the drawer-like cages
Implementation Method 2
cam means to provide, during rotation of said rotatable drum, a generally helical roto-translational motion to said drawer-like cages engaged with said supports, from said inlet to said outlet

AI summary
The washing of drawer-like cages for transporting live poultry consists of successively introducing the drawer-like cages into a rotatable drum with a horizontal axis having an inlet and an outlet, driving the continuous rotation of the rotatable drum, providing a helical roto-translational motion to the drawer-like cages from the inlet towards the outlet of the rotatable drum, and spraying the drawer-like cages with a washing liquid during their roto-translational motion.
