Vacuum Filter Shaker Mounting for Dust-Free Debris Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tank vacuums often experience reduced efficiency and premature pump motor failure due to clogged filters, which are cumbersome to clean and can spread debris when removed.
Innovation Solution
A filter shaker with a motor, eccentric, and actuator housed in a mounting assembly that periodically impacts the filter shaker housing to dislodge debris from the filter, featuring a releasable mounting system and optional locking mechanism to secure the shaker to the filter or cage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter is removed from the cage for cleaning, then the filter can be cleaned by knocking against something, but the process is cumbersome and may spread dust or debris outside the tank
Solution Approach 1:
The patent introduces a filter cleaning device as an intermediary mechanism between the filter and the user's hand. This device includes a handle and a cleaning surface that contacts the filter, allowing the filter to be cleaned by moving it against the cleaning surface rather than by direct hand-knocking. This intermediary structure eliminates the harmful effect of spreading debris while maintaining ease of operation.
Solution Approach 2:
The filter cleaning device is designed to be attached to the filter itself, making the filter clean itself through its own movement against the cleaning surface. The filter's own weight and motion are utilized for cleaning, reducing the need for complex external cleaning mechanisms and making the operation simple and self-contained.
2Ease of operation
If a filter cleaning device is added to the vacuum system, then filter cleaning becomes easier and debris containment is improved, but the device complexity increases
Solution Approach 1:
The filter cleaning device is merged with the existing filter assembly structure. The cleaning surface is integrated into the filter housing or cage, and the handle is attached to the filter itself. This merging approach allows the cleaning function to be added without requiring separate independent mechanisms, thereby minimizing the increase in overall device complexity while still providing ease of operation.
Solution Approach 2:
The filter cleaning device is designed to serve multiple functions: it provides a surface for cleaning the filter, acts as a structural support for the filter, and can be integrated with the cage or housing. This multi-functionality reduces the need for additional dedicated components, thereby limiting the increase in device complexity while achieving the goal of easier filter cleaning.
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 filter shaker effectively cleans debris from the filter without manual handling, reducing clogging and extending filter life, while being easily attachable and detachable for convenient operation.
Implementation Method 1
an eccentric (82) connected to motor shaft (80), and an actuator (86) connected to the eccentric (82). The actuator (86) is arranged to periodically impact a portion of the housing (66)
Implementation Method 2
The motor, eccentric, and actuator are carried by a housing (66)... periodically impact a portion of the housing (66)... effectively cleans debris from the filter

AI summary
A filter shaker for a filter assembly disposed in a vacuum includes a housing that removably mounts to the filter and/or a support for the filter and a vibrator assembly carried by the housing. When actuated, the vibrator assembly vibrates the filter to clean particulate matter from the filter. The vibrator assembly includes a motor that drives an eccentric and an actuator that periodically impacts against a portion of the housing to cause the vibrations. The housing includes a mounting assembly for mounting the filter shaker to the cage and/or filter in an operative position and a locking assembly for locking and unlocking the filter shaker in the operative position to prevent the filter shaker from vibrating off. In the operative position, the filter shaker covers an open end of a tubular filter and thereby forces air to be directed through filter material of the tubular filter.
