Rotary Press Suction System Cleaning via Valve-Controlled Flooding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction system cleaning methods for rotary presses are inefficient due to non-uniform cleaning effects, high costs, space requirements, and potential blockages, as well as limitations in arranging cleaning nozzles, leading to incomplete dust removal and increased expenses.
Innovation Solution
Flood part of the suction system with cleaning liquid, using shut-off valves to control the flow and terminate supply when a predetermined level is reached, creating high flow speeds and turbulence for effective cleaning, optionally enhanced with ultrasound excitation, eliminating the need for cleaning nozzles and individual feed lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cleaning nozzles are used to clean the suction system, then cleaning can be performed, but the cleaning effect is non-uniform with spray shadows where no cleaning occurs
Solution Approach 1:
The invention removes cleaning nozzles from the suction lines entirely and replaces them with shut-off valves. The cleaning medium is introduced through a separate connection point, extracting the problematic nozzle components while maintaining the cleaning function through a different mechanism.
Solution Approach 2:
The invention uses hydraulic principles by flooding the suction system with cleaning liquid through a connection in the collecting line. The liquid flow, controlled by shut-off valves, creates turbulence and high flow speeds that achieve uniform cleaning without requiring nozzles positioned along the lines.
2Reliability
If a high number of cleaning nozzles are used to improve cleaning coverage, then cleaning effectiveness increases, but the cost of supplying cleaning medium increases significantly
Solution Approach 1:
The invention merges the cleaning function into a single location (the collecting line) rather than distributing multiple nozzles throughout the system. One cleaning medium supply line serves the entire suction system, dramatically reducing the quantity of cleaning medium required while maintaining effective cleaning through the flooding and turbulence mechanism.
3Ease of operation
If cleaning nozzles are installed in the suction lines, then cleaning is possible, but the space required for cleaning components increases
Solution Approach 1:
The invention extracts cleaning nozzles and their individual feed lines from the suction system. Only shut-off valves remain in the suction lines, and the cleaning medium is introduced through a separate connection, dramatically reducing the space required for cleaning components while preserving cleaning capability.
4Ease of operation
If cleaning nozzles are placed in the suction lines, then cleaning can occur, but the cross-section of the line is narrowed and blockages can occur
Solution Approach 1:
The invention removes cleaning nozzles from the suction lines, eliminating the obstruction they cause to flow. Shut-off valves are used instead, which can be designed to minimize flow restriction, and cleaning medium is introduced through a separate connection, preserving the full cross-sectional flow capacity of the suction lines.
5Ease of operation
If cleaning nozzles are installed in the suction system, then cleaning is possible, but the inner wall surface of lines becomes uneven creating additional cleaning problems
Solution Approach 1:
The invention extracts cleaning nozzles from the suction lines, eliminating the source of surface unevenness. The shut-off valves and separate cleaning medium connection do not protrude into the flow path or create surface irregularities, maintaining smooth inner wall surfaces that are easier to clean.
6Ease of operation
If cleaning nozzles are used, then cleaning can be performed, but it is not possible to arrange cleaning nozzles at any desired point in the suction system
Solution Approach 1:
The invention creates a universal cleaning system where shut-off valves can be installed at any point in the suction lines, and the cleaning medium introduced through the collecting line can reach any section of the system. This provides flexible, adaptable cleaning capability at any desired location without requiring fixed nozzle positions.
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
Ensures reliable cleaning of all surfaces with reduced space requirements and lower expenses, achieving a high cleaning effect without the need for cleaning nozzles and their associated lines, while allowing targeted cleaning through valve control.
Implementation Method 1
In a further embodiment of the invention, the cleaning effect can be further improved by exciting the cleaning liquid with ultrasound.
Implementation Method 2
Clocked opening and closing of the shut-off valves also creates high flow speeds and turbulence in the lower areas below the shut-off valves, which ensure that good cleaning also takes place below the shut-off valves.

AI summary
The method involves guiding cleaning fluid to a suction system (10), and closing the suction system in an area of a press chamber of a press. A part of the suction system is rinsed using the cleaning fluid, and the cleaning fluid is discharged to the press chamber. Rinsing of the suction system using the cleaning fluid is terminated when a level of the cleaning fluid in the suction system reaches a preset value. The cleaning fluid is excited with ultrasonic waves. A level sensor (30) is assigned to a collecting line (24) that is connected with a control device. An independent claim is also included for a device for cleaning a suction system for a rotary press comprising a suction nozzle in a press chamber.
