Vacuum Filter Press for Powder Soluble Component Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing soluble components from powder mixtures are inefficient for small particle sizes, leading to prolonged processing times and potential motor overload, and require significant space and cost for filtration, especially when dealing with large amounts of particles.
Innovation Solution
An apparatus and method utilizing a wash tank with a vacuum pump, filter, and backwashing system to separate soluble components from poorly soluble components, where the soluble component is dissolved in a solvent and then removed through a pipe line, with a controller managing the process to prevent overload and efficiently discharge the powder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a centrifugal method is used to separate powder from solution, then separation efficiency is improved, but motor overload and breakdown occur when large amounts of particles are contained
Solution Approach 1:
The patent extracts the solid-liquid separation function from the centrifugal system and implements it through a filter press mechanism. The filter press separates the slurry into filtrate and solid residue through filtration, eliminating the need for high-speed rotation and motor-driven centrifugal force, thus preventing motor overload while maintaining separation efficiency.
Solution Approach 2:
The patent replaces the mechanical centrifugal separation system with a filtration-based system. Instead of using rotational mechanical force to separate particles, the system uses a filter medium to physically separate solids from liquids, substituting a potentially overloaded mechanical system with a more reliable filtration process.
2Productivity
If a belt filter is used for solid-liquid separation, then washing/desalting is effectively processed, but large amount of space and cost for mounting is required
Solution Approach 1:
The filter press units are designed to be stackable and nestable, allowing multiple filtration chambers to be arranged vertically or in compact configurations. This nesting arrangement enables effective solid-liquid separation while minimizing the floor space and mounting area required compared to traditional belt filter systems.
Solution Approach 2:
The patent transitions from a horizontal space-consuming belt filter to a vertical stackable filter press design. By utilizing the vertical dimension for stacking multiple filtration chambers, the system achieves effective washing and separation while dramatically reducing the horizontal mounting space and cost.
3Productivity
If sedimentation method is used for small particles, then separation is achieved, but process cycle is extended and workability deteriorates
Solution Approach 1:
The patent incorporates a pre-coat layer on the filter medium before actual filtration. This preliminary action of depositing a layer of fine particles creates a more effective filtration surface that can immediately capture small particles, eliminating the need for prolonged sedimentation time and significantly reducing the overall process cycle time.
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
The apparatus effectively collects and recycles poorly soluble component-containing powder by preventing overload and reducing initial costs and space requirements, allowing for efficient separation regardless of particle size or amount.
Implementation Method 1
a pump, when the pump is in operation, that is connected with the outside end of the pipe line and applies vacuum negative pressure in the pipe line
Implementation Method 2
a backwashing means that injects a solvent to the filter through the pipe line to remove, from the filter, the soluble component-removed powder stuck to the filter
Implementation Method 3
a solvent dissolving the soluble component contained in the powder
