Nozzle-Brush Filter with Motor Reducer for Continuous Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic cleaning systems for liquid filtration are unable to effectively perform both coarse and fine particle filtration, especially in high-pressure and high-flow rate applications like surface water treatment, where pollutants such as tree branches, leaves, and fine particles accumulate, leading to clogging and incomplete cleaning.
Innovation Solution
A Nozzle-Brush Automatic Cleaning Filter with Motor Reducer that uses a combined brush and nozzles device with adjustable revolutions, capable of performing two-stage cleaning: brush cleaning for coarse particles and nozzle cleaning for fine particles, utilizing a motor reducer to maintain continuous filtration without manual disassembly, and electrically controlled drainage valves to manage pressure and pollution levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-stage cleaning system is used, then the device complexity is reduced, but the cleaning effectiveness for both coarse and fine particles is insufficient
Solution Approach 1:
The cleaning system is segmented into two distinct stages: a first cleaning device with brushes for coarse particle removal, and a second cleaning device with nozzles for fine particle removal. This segmentation allows each component to specialize in removing specific particle sizes, thereby improving overall cleaning effectiveness while maintaining manageable system complexity through modular design
Solution Approach 2:
The patent merges two different cleaning mechanisms (brush cleaning and nozzle cleaning) into a single integrated filter system. The first cleaning device and second cleaning device are combined within the same filter housing, sharing common components such as the filter element and control system, which resolves the contradiction by achieving comprehensive cleaning without proportionally increasing device complexity
2Productivity
If manual disassembly is required for cleaning, then the device complexity is reduced, but the productivity and continuous operation capability are reduced
Solution Approach 1:
The filter system performs self-service cleaning through automated cleaning devices that are activated based on pressure differential or time-based control. The first and second cleaning devices automatically remove accumulated particles from the filter element without requiring manual intervention, enabling continuous operation and significantly improving productivity while the automation is managed through simple control mechanisms
Solution Approach 2:
The cleaning devices are designed to perform preliminary cleaning actions before the filter element becomes completely blocked. By continuously or periodically activating the brush and nozzle cleaning devices, the system prevents severe clogging and maintains filtration productivity without interrupting the overall filtration process
3Productivity
If high flow rates are maintained, then the productivity is improved, but the head loss and pressure requirements increase
Solution Approach 1:
The cleaning devices operate continuously or periodically to maintain the filter element's permeability throughout the filtration process. This continuous cleaning action prevents the accumulation of particles that would otherwise increase head loss, allowing the system to maintain high flow rates and productivity without excessive pressure requirements
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
Ensures efficient removal of both coarse and fine particles from the filter screen during operation, maintaining high flow rates and low head loss, with a robust structure that resists pressure and deformation, allowing for automatic and continuous filtration without interrupting the process.
Implementation Method 1
motor (9) actuates the combined brush and nozzles device (12). Thereby, this device performs a vertical and linear displacement creating a helical movement
Implementation Method 2
The opening of this exhaust valve creates a vacuum effect at the internal of the nozzles. Meanwhile, the motor continues to execute the helical movement of the combined brush and nozzles device (12). This helical movement allows the nozzles to remove the accumulated fine particles from the internal surface of the screen by means of the vacuum suction
Implementation Method 3
the exhaust valve on the drainage line (16) opens to atmosphere creating a strong hydraulic current discharging the dirt out of the filter
