Top-Loading Centrifugal Dryer for Mixed-Size Container Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drying centrifuges are inefficient for containers of varying dimensions, require complex feeding and discharge systems, and lack convenient access for cleaning and maintenance, leading to prolonged processing times and difficulty in water drainage.
Innovation Solution
A centrifugal dryer with a vertical axis of rotation that allows loading from above, featuring a horizontally movable loading/unloading platform and a vertically actuated retaining/pressure plate, which adapts to container dimensions and ensures efficient drainage and easy access for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the centrifugal cage is positioned above the feed conveyor belts to facilitate loading, then the loading process is simplified, but the travel of the lifting table must always be greater than the maximum height of processable crates, resulting in long loading and unloading times
Solution Approach 1:
The patent inverts the conventional arrangement by positioning the centrifugal cage below the feed conveyor belts instead of above. Containers are loaded from above through the opening at the top of the cage, allowing the lifting table to have minimal travel distance while still enabling easy loading. This inversion resolves the contradiction by simplifying the loading process without requiring excessive lifting table travel.
2Ease of operation
If the centrifugal cage is positioned above the feed conveyor belts, then loading is easier, but access for cleaning and maintenance of the centrifugal cage and drainage devices becomes more difficult
Solution Approach 1:
By inverting the position of the centrifugal cage to be below the feed conveyor belts, the patent improves accessibility for cleaning and maintenance. The opening at the top of the cage allows easy access to the interior of the cage and the drainage devices located at the bottom, eliminating the need for complex disassembly or difficult-to-reach positions that would result from placing the cage above the conveyors.
3Productivity
If a stacking device is arranged upstream of the spin dryer to stack crates of the same dimensions, then the crates can be efficiently fed into the centrifuge, but the system cannot process crates of different dimensions
Solution Approach 1:
The patent eliminates the need for a dedicated stacking device by designing a universal loading system where containers of various dimensions can be individually loaded from above onto the lifting table. The centrifugal cage and lifting mechanism are designed to accommodate different container sizes without requiring pre-stacking, making the system versatile while maintaining efficient feeding through direct loading.
4Adaptability or versatility
If the lifting table travel is increased to accommodate the maximum height of crates with fixed side walls, then all container types can be processed, but the loading and unloading times are long even for crates with folded side walls
Solution Approach 1:
By inverting the cage position and allowing loading from above, the patent enables the lifting table to have minimal travel distance. Containers with folded side walls or low profiles can be quickly loaded and unloaded without requiring the lifting table to traverse the full height of tall containers, thus reducing cycle time while still accommodating various container types through the universal top-loading design.

AI summary
Drying centrifuge for individual containers with fixed or open or closed hinged side walls or for stacks of containers (10, 10a) whose height is not greater than the maximum height of the individual containers that can be processed, which are fed (H) to the drying centrifuge via a feed conveyor (4x) and a subsequent conveyor (4) in order to then bring them horizontally, by means of conveyor belts (4a) or transfer devices which act laterally on the containers, into an area above the centrifuge cage (2), which is rotatably (2s) mounted (2s) on a frame (1) within a fixed encompassing structure for collecting and draining the centrifuge water by means of a shaft (2y) according to a vertical axis (2r) and is driven by a motor (2m), wherein the cage has a horizontal floor (2a) from which, in the direction of the loading/unloading opening of the cage (2), rungs (2b, 2c) project, between which the containers (10, 10a) are placed during the Spin cycle,between a loading/unloading platform (2t) and a retaining/pressure plate (3a), both of which act vertically and coaxially to the axis of rotation of the cage (2) (3w, 2v), wherein the cage (2) is arranged below the plane for the transfer of the containers (10, 10a), which are fed in by means of conveyor belts (4a) with their bottoms (10, 10a) facing upwards, wherein the loading/unloading opening of the cage (2) is oriented upwards, wherein the loading/unloading platform (2t) together with the shaft (2u) inside the cage (2) acts vertically and rotates together with it (2r), and wherein the retaining/pressure plate (3a), which is rotatably mounted (3r) on a rod (3f) when idling, acts vertically (3v) to hold the individual container (10, 10a), or the stack of containers, inside the cage (2) during centrifugal force application. Loading/unloading platform (2t) adjacent, to be kept back.
