Densimetric Separation Table With Fluidification Pre-Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing densimetric separation tables have limitations in loading capacity and separation efficiency, particularly when handling materials with significantly different densities like organic matter and inert materials, due to inefficient initial separation methods.
Innovation Solution
The densimetric separation table incorporates a fluidification channel with adjustable airflow and inclination, allowing prior separation of lightweight materials before reaching the main separation base, combined with chevrons and an additional base to enhance separation efficiency and reduce table size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If material is passed directly to the working base for separation, then separation function is provided, but loading capacity is limited and separation time is increased
Solution Approach 1:
The patent applies preliminary action by introducing a fluidification channel before the working base to perform initial separation of lightweight materials. This pre-separation step removes a portion of lightweight materials before they reach the main separation area, thereby increasing the loading capacity and reducing the time required for complete separation in the working base.
2Volume of moving object
If table size is reduced to decrease equipment footprint, then space efficiency is improved, but separation efficiency may be compromised
Solution Approach 1:
The patent applies segmentation by dividing the separation process into two distinct stages: initial separation in the fluidification channel and main separation in the working base. This segmentation allows the overall separation function to be achieved in a more compact configuration while maintaining high separation efficiency through the coordinated action of both stages.
3Productivity
If conventional separation method is used without fluidification channel, then device complexity is low, but loading capacity and separation efficiency are insufficient
Solution Approach 1:
The patent applies pneumatics by introducing a fluidification channel that uses airflow to fluidize and separate lightweight materials before they reach the working base. This pneumatic pre-separation mechanism significantly increases loading capacity and separation efficiency, with the added complexity being justified by the substantial improvement in productivity.
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 doubles the loading capacity and separation efficiency, reducing the overall separation time and table size while maintaining high separation quality, especially for compost and inert materials.
Implementation Method 1
In said fluidification channel, a first airflow is passed through a channel treatment base
Implementation Method 2

Implementation Method 4
separate according to their specific weight and shape
Implementation Method 5
The fraction which can be brought to the surface of the bulk material by vibration is sucked off from the surface

AI summary
Densimetric separation table. The table (1) comprises a main separation box (2) in which two materials are separated by means of the fluidification of the lightweight material and the vibration of a working base of the box (3). The table also comprises a fluidification channel (7) for the prior separation of the materials, comprising a conduit (8) with a channel treatment base (9) allowing the passage of an airflow therethrough, such that a first part of lightweight materials is directed to the suction system (6), a second part is directed to a lightweight material outlet (4), and a third part is directed to the working box (2) mixed with the heavy material. The table comprises a fan (10) for generating the airflow and a duct (11) through which the airflow is directed to the conduit (8) where it is forced through the channel treatment base (9).
