Filter Device Coupling Cleaning and Discharge Drives
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices require significant installation space and energy due to independent rotary drives for cleaning and discharge devices, which limits their efficiency and compactness.
Innovation Solution
A coupling device that allows the cleaning and discharge devices to share a common rotary movement, eliminating the need for transmission gears and enabling a space-saving, energy-efficient configuration, where one device can be driven intermittently while the other is driven continuously, or vice versa, depending on the application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If independent rotary drives are used for cleaning device and discharge device, then each device can be operated independently, but installation space and energy consumption increase significantly
Solution Approach 1:
The patent combines the rotary drive functions for the cleaning device and discharge device into a single common drive mechanism. The drive shaft rotates both the cleaning device (with cleaning nozzles) and the discharge device (with discharge openings) simultaneously, eliminating the need for separate independent drives and reducing installation space while maintaining coordinated operation of both devices
Solution Approach 2:
The common drive shaft serves multiple functions: it drives the cleaning device rotation, drives the discharge device rotation, and provides the rotational motion for both devices to work in coordination. This multi-functional drive mechanism replaces what would traditionally require two separate drive systems, reducing space and complexity
2Ease of operation
If independent rotary drives with gear stages are used for cleaning and discharge devices, then each device can be controlled independently, but drive energy consumption increases greatly
Solution Approach 1:
The patent merges the drive energy requirement for both cleaning and discharge devices into a single drive source. The common drive shaft transmits rotational energy to both devices simultaneously, eliminating the need for two separate motor-gearbox systems and significantly reducing total energy consumption while maintaining the ability to control each device's operation through the shared drive mechanism
3Area of stationary object
If common rotary drive is used for cleaning device and discharge device, then installation space is reduced and energy efficiency is improved, but device complexity increases
Solution Approach 1:
The patent employs a nested configuration where the discharge device is positioned within or alongside the cleaning device, and both share the same drive shaft. This nested arrangement allows the common drive mechanism to rotate both devices in a compact configuration, reducing installation space while the shared drive structure actually simplifies rather than complicates the overall mechanism compared to having two independent drives

AI summary
Filter apparatus, consisting of at least—a filter (14), which is divided into individual filter segments,—a cleaning device (19), which has, associated with each filter segment, a partial cleaning unit (20, 21, 22), which can be moved along the cleaning device and which cooperates with a removal device (23), and—a control device (40), which activates at least one partial cleaning unit for cleaning, whereas at least one further partial cleaning unit remains inactive during this cleaning, wherein the control device (40) has a coupling device, which in one position of the coupling device, connects the cleaning device (19) to the discharge device (23) for a common rotary movement and, in another position of the coupling device, separates them from one another.
