Method for treating laundry and drainage press
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial laundries face space and cost inefficiencies due to the large footprint of dewatering presses and the need for additional facilities like laundry cake breakers, as existing dewatering presses require significant space and reduce pressing capacity when compacted.
Innovation Solution
Implementing radial compression within the dewatering press to break up the laundry cake transversely, eliminating the need for a separate laundry cake breaker and optimizing the dewatering press design to reduce space requirements while maintaining dewatering performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the distance between the columns of the dewatering press is reduced to save space, then the space required for the dewatering press is reduced, but the size of the press basket must be reduced and thus the pressing capacity is reduced
Solution Approach 1:
The patent combines the function of breaking up the laundry cake with the dewatering press itself by adding radial compression capability. This eliminates the need for a separate laundry cake breaker facility, allowing space savings without reducing pressing capacity. The press now performs both dewatering and cake breaking functions within the same device boundaries.
Solution Approach 2:
The patent introduces radial compression (transverse to the pressing direction) as an additional dimension of action. While the press ram compresses vertically, the radial compression means apply force horizontally to break up the laundry cake. This multi-directional compression approach enables effective cake breaking within the confined space between columns without reducing press basket size.
2Ease of operation
If a separate laundry cake breaker is added to break up the laundry cake, then the laundry cake can be effectively broken up, but the space required for laundry facilities increases
Solution Approach 1:
The patent merges the laundry cake breaking function into the dewatering press by equipping it with radial compression means. This integration eliminates the need for a separate laundry cake breaker, reducing the overall facility footprint while maintaining effective cake breaking capability through the combined vertical and radial compression actions.
Solution Approach 2:
The dewatering press is transformed into a multi-functional device that performs both dewatering and laundry cake breaking operations. The radial compression means enable the press to break up the laundry cake as part of its primary function, making the facility more versatile and reducing the total number of dedicated facilities needed.
3Ease of operation
If radial compression is applied transversely to the pressing direction, then the laundry cake is broken up more easily and effectively, but the device complexity increases
Solution Approach 1:
The compression action is segmented into two independent components: vertical compression by the press ram and radial compression by separate compression means. This segmentation allows each component to be optimized for its specific function while working together to achieve effective laundry cake breaking. The radial compression means can be independently controlled and positioned.
Solution Approach 2:
The radial compression means are designed to be movable rather than fixed, allowing them to engage with the laundry cake only when needed for breaking. This dynamic approach enables the system to adapt its complexity - using radial compression only when required - while maintaining simplicity during normal dewatering operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach allows for efficient and space-saving laundry treatment by breaking up the laundry cake within the dewatering press, reducing the need for additional facilities and minimizing space usage without compromising dewatering capacity.
Implementation Method 1
a lifting cylinder is arranged on columns, which has a press ram with which the laundry is drained in the press basket. By pressing the laundry together in the press basket, a laundry cake is created
Implementation Method 2
the laundry pressed together to form the laundry cake is broken up by radial compression while still in the dewatering press. The compression for breaking up the laundry cake now takes place radially on the lateral surface of the laundry cake, namely transversely to the pressing direction of the press ram

AI summary
Dewatering presses (11) for dewatering the laundry (10) and subsequent laundry cake crushers take up a great deal of space. The invention creates a method for treating laundry (10) and a dewatering press (11) with which laundry (10) can be treated in an efficient and space-saving manner. For this purpose, the laundry (10) pressed together to form a laundry cake (20) is broken up in the dewatering press (20) by radial compression.
