Milking Pulsator Filtering Member Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pneumatic pulsators in milking plants face issues with dust accumulation, leading to reduced air volume, faster cyclical pressure alternation, and increased wear on parts, which can cause teat damage and require frequent maintenance, as existing filters are ineffective and difficult to clean.
Innovation Solution
A pulsator design with a filtering member exposed on the outer casing, featuring a wide filtering surface and an inner screen that collects dust, allowing for easy cleaning without disassembly and reducing the need for frequent maintenance, thereby preventing dust from reaching the internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If air is taken from the outer environment through slots in the pulsator casing, then the pulsator can operate with simple structure and easy air intake, but dust and pollutants enter the pulsator causing accumulation that reduces air volume and modifies pulsation cycle durations
Solution Approach 1:
The pulsator casing incorporates a filtering member with porous structure that allows air to pass through while blocking dust and pollutants. The porous material provides effective filtration without significantly increasing device complexity, resolving the contradiction between simple structure and dust prevention.
Solution Approach 2:
A filtering member is introduced as an intermediary element between the outer environment and the pulsator interior. This mediator allows beneficial air intake while blocking harmful dust particles, solving the contradiction between easy air access and dust accumulation prevention.
2Object-affected harmful factors
If a grille or filtering member is provided inside the pulsator body to prevent dust entry, then dust protection is improved, but the filter becomes difficult to clean and requires disassembly of the pulsator
Solution Approach 1:
The filtering member is extracted from the interior of the pulsator body and positioned on the outer surface of the casing. This extraction allows the filter to be easily accessed and cleaned without disassembling the pulsator, while still providing effective dust prevention at the air intake points.
Solution Approach 2:
Instead of placing the filter inside the pulsator as conventionally done, the filtering member is inverted to the outer surface of the casing. This inversion makes the filter externally accessible for easy cleaning while maintaining its dust-blocking function, resolving the contradiction between dust protection and maintenance ease.
3Reliability
If the filtering surface is increased to improve filtering endurance, then dust collection capacity is enhanced, but the pulsator size increases
Solution Approach 1:
The filtering member utilizes the outer surface of the pulsator casing in a dimensional sense, expanding the filtering area across the available exterior surface. This approach increases filtering endurance by providing larger filtering surface area without significantly increasing the overall pulsator volume or footprint.
Solution Approach 2:
The outer casing surface serves dual functions: structural enclosure of the pulsator and filtering surface for dust collection. This multi-functionality increases filtering endurance without requiring additional space, as the casing itself provides the filtering area.
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 solution effectively prevents dust accumulation, ensuring optimal pulsator performance, extending the lifespan of moving parts, and reducing maintenance needs, while providing a larger filtering surface that increases filtering endurance and simplifies cleaning interventions.
Implementation Method 1
said outer wall defining a portion (23) overlooking the environment outside the pulsator and intended for atmospheric air admission into the pulsator, said portion (23) being a filtering portion
Implementation Method 2
pneumatic pulsators are devices operating in environments that often are highly polluted by very high amounts of dust present in air... Dust is sucked by the pulsator together with air necessary for generating the cyclical alternation of the pressure signals
