Feeding Screw Machine Emptying Opening for Independent Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing feeding screw machines for processing screw machines are difficult to clean efficiently, requiring complex disassembly and downtime for maintenance.
Innovation Solution
A feeding screw machine design with an emptying opening in the housing allows for independent cleaning without disassembly, featuring a screw conveyor shaft that can rotate in opposite directions for thorough cleaning, and includes a drying device for quick restart.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the feeding screw machine is connected laterally to the processing screw machine without an emptying opening, then the material can be continuously fed from the supply opening through the housing bore to the processing screw machine, but the cleaning becomes complex and time-consuming requiring disassembly and use of the processing screw machine for discharging
Solution Approach 1:
The patent extracts the discharging function from the processing screw machine by providing a separate emptying opening in the feeding screw machine's housing. This allows material and cleaning agents to be discharged independently from the feeding screw machine without involving the processing screw machine, thereby simplifying cleaning operations while maintaining continuous feeding capability through the lateral connection.
2Area of stationary object
If the feeding screw machine is designed with a lateral connection to the processing screw machine, then the space utilization is improved, but the cleaning accessibility is reduced requiring complex disassembly procedures
Solution Approach 1:
The patent segments the cleaning function from the feeding operation by providing separate openings: a supply opening for material input, a feeding opening for material output to the processing screw machine, and an emptying opening for material and cleaning agent discharge. This segmentation allows the feeding screw machine to maintain its compact lateral connection design while providing independent access for cleaning operations without requiring disassembly.
3Ease of operation
If the screw conveyor shaft is designed to rotate in opposite directions, then the cleaning thoroughness is improved by conveying material and cleaning agents in both directions, but the control complexity increases
Solution Approach 1:
The patent implements periodic action by enabling the screw conveyor shaft to rotate in opposite directions. During normal operation, the shaft rotates in the conveying direction to feed material to the processing screw machine. During cleaning, the shaft rotates in the opposite direction to convey material and cleaning agents toward the emptying opening. This periodic reversal of rotation direction enables thorough cleaning while using the existing drive mechanism without adding complex control systems.

Function Achieved in This Case
Enables easy, fast, and reliable cleaning of the feeding screw machine, reducing downtime and maintaining operational efficiency.
Implementation Method 1
at least one screw conveyor shaft rotatably arranged in the at least one housing bore, for conveying the material in a conveying direction from the supply opening to the feeding opening
Implementation Method 2
Material located in the at least one housing bore and/or cleaning agent located in the at least one housing bore may be discharged from the at least one housing bore through the emptying opening
Data Source
AI summary
A feeding screw machine serves for feeding a processing screw machine. The feeding screw machine comprises a housing with at least one housing bore formed therein. An associated screw conveyor shaft is rotatably disposed in the at least one housing bore to convey material in a conveying direction from a supply opening to a feeding opening. An emptying opening is formed in the housing. The emptying opening enables an easy, fast and reliable emptying and cleaning of the feeding screw machine independently of the processing screw machine.
