Vertical Rotating Tubular Container for Granular Material Processing

Solution Overview

Problem

Existing cleaning devices for processing materials, such as those containing granular matter or lumpy foreign matter in raw gravel, face challenges in achieving high throughput while requiring minimal space and efficient energy input.

Innovation Solution

A cleaning device with a tubular container disposed upright, featuring a centered axle device and engaging dogs in the processing chamber, allows for rotational movement of the container, enabling enhanced material processing and cleaning effects. The device includes adjustable working elements and spacers to optimize processing conditions, allowing for flexible operation and high filling capacities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a horizontal rotary drum with off-center rotor is used, then mechanical treatment of crushed rock is achieved, but the apparatus requires considerable space due to low filling capacity

Engineering Contradiction:

Improvefilling capacityVSAvoidspace requirement

Core Design Contradiction:

ProductivityVSArea of stationary object

Solution Approach 1:

The patent inverts the conventional design by making the container rotate instead of the central agitator. This allows the processing chamber to be compact and vertical while still achieving effective material treatment through the rotating container wall with engaging dogs, thereby increasing filling capacity without requiring considerable horizontal space

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent transitions from a horizontal drum configuration to a vertical container configuration. This dimensional change allows gravity to assist material movement and enables higher filling capacity within a smaller footprint, resolving the contradiction between space requirement and productivity

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Productivity

If a stationary tubular container with vertical agitator is used, then less space is required, but throughput is limited due to low energy input

Engineering Contradiction:

ImprovethroughputVSAvoidenergy input intensity

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent inverts the conventional design by making the container rotate instead of the central agitator. This allows the processing chamber to be compact and vertical while still achieving effective material treatment through the rotating container wall with engaging dogs, thereby increasing filling capacity without requiring considerable horizontal space

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent employs dynamic engagement between the rotating container wall with engaging dogs and the material, creating variable mechanical action throughout the processing chamber. This dynamic approach increases energy input intensity and throughput compared to static agitator designs

Inventive Principle:

Principle #15Dynamics

3Manufacturing precision

If a rotating center axis is used, then material processing is achieved, but the capturing effect and milling quality are reduced compared to rotating outer wall

Engineering Contradiction:

Solution Approach 1:

The patent inverts the conventional design by making the container rotate instead of the central agitator. This allows the processing chamber to be compact and vertical while still achieving effective material treatment through the rotating container wall with engaging dogs, thereby increasing filling capacity without requiring considerable horizontal space

Inventive Principle:
