Filter Press Washing Apparatus With Articulated Support Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior filter press washing apparatuses require significant space above the filter plates and are inefficient due to lengthy movement times for the spray bar, which increases the overall time needed to wash all filter cloths.
Innovation Solution
A modular washing apparatus with a support structure and a carrier system using link arms and cogwheels, allowing the spray bar to move vertically between filter plates with reduced height and faster movement, minimizing space usage and transfer time between plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spray bar supported on vertical support bars extending above the filter plates is used, then the spray bar can be moved vertically between filter plates, but the space required above the filter plates becomes considerable and the movement time increases
Solution Approach 1:
The support bars are made dynamically adjustable in length rather than fixed. The first support bar connects the carrier to the spray bar and can vary its effective length during vertical movement, allowing the spray bar to reach between filter plates without requiring excessive fixed space above them. This dynamic adjustment resolves the contradiction by providing full movement capability while minimizing the static volume requirement.
2Ease of operation
If vertical support bars extend above the filter plates to support the spray bar, then the spray bar can be positioned between filter plates, but the time to lower and raise the spray bar becomes rather long
Solution Approach 1:
The support bars with adjustable lengths enable faster positioning of the spray bar between filter plates. The dynamic adjustment mechanism allows the support structure to adapt quickly during movement, reducing the time required to lower and raise the spray bar compared to fixed support structures that must traverse the entire extended distance.
Solution Approach 2:
The support structure is divided into multiple segments (first support bar, second support bar, link arms) that can move and adjust independently. This segmentation allows different parts of the support system to optimize their positions during movement, reducing overall movement time while maintaining the capability to position the spray bar accurately between filter plates.
3Ease of operation
If a portal with vertical support bars is used to support the spray bar, then the spray bar can move vertically, but the structure becomes complex and requires considerable space
Solution Approach 1:
The complex portal structure with vertical support bars is segmented into simpler components: a carrier that moves along the filter press and link arms that connect to the spray bar. This segmentation reduces structural complexity while maintaining the vertical movement capability, as each segment can be independently controlled and positioned.
Solution Approach 2:
The static portal structure is replaced with dynamic, adjustable link arms that can change their configuration during operation. This dynamic approach reduces the need for a rigid, space-consuming portal structure while still providing the necessary support and movement capability for the spray bar.

AI summary
The filter press consists of a pack of filter plates (100)and a support structure (700) extending in a longitudinal direction (A1) along the pack of filter plates (100). The washing apparatus comprises a carrier (600) movably supported on the support structure (700), a support arm (300) comprising a first end (311), a second opposite end (322) and at least one articulated joint (J3) between the first end (311) and the second end (322), and a spay bar (200). The first end (311) of the support arm (300) is connected to the carrier (600) with a first articulated joint (J1)and the second end (322) is connected to the spray bar (200) with a second articulated joint (J2). The spray bar (200) is movable in a plane (P1) between a spaced apart pair of filter plates (100) with the support arm (300) and in the longitudinal direction (A1) with the carrier (600).
