Vertical Drum Filter Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air filter systems with horizontally arranged drum filters require a large area for installation, making them space-intensive and costly due to the need for additional space to accommodate the drive device and movement of suction elements, which limits their use in areas with space constraints.
Innovation Solution
The air filter system is designed with vertically oriented drum filters, where the carriage moves vertically and incorporates a counterweight for weight compensation, allowing the suction element to be positioned above the drum filter, thus utilizing the existing space more efficiently and eliminating the need for additional floor space. The suction element is mounted on an elongate element that rotates and moves axially, enabling a helical cleaning path without increasing the base area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If drum filters are arranged horizontally with suction elements moved by a horizontal carriage, then the cleaning function is achieved, but a large base area is required accommodating the drive device and suction element movement space
Solution Approach 1:
The patent transitions from horizontal drum filter arrangement to vertical arrangement, changing the operational dimension from horizontal plane to vertical space. The suction element moves vertically along the drum's longitudinal axis rather than horizontally, utilizing the vertical dimension to achieve cleaning accessibility without increasing base area.
Solution Approach 2:
The patent inverts the conventional horizontal arrangement by positioning the drum filter vertically and moving the suction element along the longitudinal axis from end to end, rather than moving horizontally across the drum surface. This inversion resolves the space conflict by using vertical clearance instead of horizontal footprint.
2Area of stationary object
If the suction element is moved horizontally along the drum surface, then cleaning coverage is achieved, but additional floor space must be allocated for the drive device and movement zone
Solution Approach 1:
The invention moves the cleaning operation from the horizontal plane to the vertical dimension by arranging the drum filter vertically and moving the suction element along the longitudinal axis. This allows the drive device and movement zone to be positioned above the drum rather than requiring additional floor space, while maintaining complete cleaning coverage through axial movement.
3Productivity
If a horizontal carriage with drive device is used for suction element movement, then cleaning function is provided, but the base area is increased due to lateral zone requirements
Solution Approach 1:
The patent inverts the conventional horizontal carriage arrangement by implementing vertical movement of the suction element along the drum's longitudinal axis. The drive device is positioned above the drum rather than beside it, eliminating the need for lateral zones and reducing base area while maintaining cleaning efficiency through axial reciprocating motion.
Solution Approach 2:
The invention changes the movement dimension from horizontal to vertical, allowing the drive device and suction element to occupy vertical space above the drum filter rather than requiring additional horizontal base area. This dimensional transition resolves the contradiction between cleaning efficiency and space utilization.
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 configuration significantly reduces the space required for the air filter system, allowing for a more compact setup without additional floor space, while ensuring effective cleaning of the filter cake on the drum filter's lateral surface through the combined vertical and rotational movements of the suction element.
Implementation Method 1
a suction element is moved both in a circle along the inside of the lateral surface and axially in the direction of the longitudinal axis of the drum filter in order to suck off the filter cake
Implementation Method 2
for the up and down movement with very little drive power, a counterweight guided via a deflection for the partial or almost complete Weight compensation is provided
