Solution Overview

Problem

Existing air jigs for dry processing of raw materials, such as coal, have limited capacity and are unable to efficiently separate heavy and light materials, limiting their throughput and product separation capabilities.

Innovation Solution

The design involves stacking at least two material carriers one above the other with a bypass air line connecting the air supply line to the gap between them, allowing additional air to be introduced, which maintains the pulsating flow and energy efficiency, while reducing leakage losses and investment costs, and enabling the processing of approximately twice the material without increasing the areal layout or filter system size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the area of the jig is increased to increase capacity, then the processing capacity is improved, but the air requirement and filter system size increase accordingly

Engineering Contradiction:
Improveprocessing capacityVSAvoidair requirement
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent transitions from a single horizontal plane configuration to a vertical stacking configuration with multiple seed trays arranged one above the other. This dimensional change allows the air stream to flow vertically through multiple trays simultaneously, increasing processing capacity without proportionally increasing the horizontal air distribution area or filter system size.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent implements a nested structure where multiple seed trays are stacked vertically within a single air jig housing. The air stream flows through the lower tray first, then continues upward through the upper tray, creating a nested processing path that maximizes the use of available vertical space and air flow capacity.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Manufacturing precision

If multiple seed material carriers are arranged one above the other to improve separation success, then the separation capability is improved, but the capacity is not increased

Engineering Contradiction:
Improveseparation successVSAvoidcapacity
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent utilizes the vertical dimension to stack multiple seed trays, allowing the air stream to sequentially pass through each tray. This vertical arrangement maintains the separation functionality of multiple trays while simultaneously increasing the overall processing capacity by handling multiple material streams in parallel within the same horizontal footprint.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If the surface of one tray is increased to increase throughput, then the processing capacity is improved, but the filter system and air requirement increase accordingly

Engineering Contradiction:
ImprovethroughputVSAvoidfilter system size
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Instead of increasing the horizontal surface area of a single tray, the patent increases throughput by adding vertical layers of trays. The same air stream serves multiple trays in sequence, thereby increasing total processing capacity without requiring a proportionally larger filter system or air distribution infrastructure.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Productivity

If at least two setting material carriers are stacked one above the other in the same air flow, then the processing capacity is increased, but the air distribution and energy efficiency may be compromised

Engineering Contradiction:
Improveprocessing capacityVSAvoidair flow energy efficiency
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent designs the vertical stacking configuration so that the air stream continuously flows through multiple trays without interruption or significant energy loss. The air funnel positioned at the bottom generates a continuous upward flow that passes through each tray in sequence, maintaining energy efficiency while processing multiple layers of material simultaneously.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent utilizes pneumatic principles by employing an air funnel and pulsating air stream to fluidize and transport material through vertically stacked trays. The controlled air flow maintains optimal energy efficiency by creating the necessary fluidization state for separation while minimizing excessive pressure drops or energy waste across multiple trays.

Inventive Principle:
Principle #29Pneumatics and hydraulics

AI summary

The invention relates to an air jigging machine, comprising a material input device, at least one jigging-material carrier provided with openings, and a dispensing device for heavy material and light material, an air flow flowing through the jigging-material carrier as working air, the air flow being composed of a partial flow that constantly flows through the jigging-material carrier and a pulsed partial flow superposed thereon, characterized in that at least two jigging-material carriers (15, 16), which are arranged one over the other at a distance from each other and through which the air flow introduced into the air funnel (28) flows and which each have a material input (13, 14) and an dispensing device (20), are arranged above the air funnel (28), which is connected to an air supply line (32) that has a pulsing valve (34) inserted therein. The intermediate space between the jigging-material carriers (15, 16) is enclosed by an outer wall (40), and in order to increase the air amount to be supplied to the upper jigging-material carrier (15), at least one bypass air line (50a, b) that bypasses the lower jigging-material carrier (16) branches off from the air supply line (32) downstream of the pulsing valve (34) and is connected to the intermediate space between the two jigging-material carriers (15, 16) in such a way that an additional working air flow can be introduced through the bypass air line (50a, b) into the intermediate space between the jigging-material carriers (15, 16).
