Cellular Wheel Sluice Sealing Lips Abrasion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The friction between sealing lips and surfaces in cellular wheel sluices causes abrasion, contaminating the conveyed material and reducing its quality, as the sealing mechanism introduces foreign material inclusions.
Innovation Solution
Using sealing lips and surfaces made from materials that are part of the conveyed material itself, ensuring that any abrasion is from the same material, thus maintaining the material's integrity and preventing contamination, with options including polyethylene, polypropylene, and other thermoplastics for the sealing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sealing lips made of conventional sealing materials (EPDM, PVC, PTFE, etc.) are used, then sealing effectiveness is improved, but material contamination occurs due to abrasion
Solution Approach 1:
The sealing lips are made from the same thermoplastic material as the conveyed material (e.g., polyethylene sealing lips for polyethylene granules). This homogeneity ensures that any abrasion particles generated are identical to the conveyed material, preventing contamination and maintaining material quality while preserving sealing effectiveness.
Solution Approach 2:
The invention changes the material parameter of the sealing lips from conventional sealing materials to thermoplastic materials matching the conveyed material. This parameter change allows the sealing mechanism to generate acceptable abrasion particles while eliminating foreign material contamination, thus resolving the contradiction between sealing reliability and material purity.
2Duration of action of stationary object
If hard sealing materials are used to resist wear, then sealing durability is improved, but abrasion contamination of conveyed material increases
Solution Approach 1:
By making the sealing lips from the same thermoplastic material as the conveyed material, the invention ensures that wear particles are homogeneous with the conveyed material. This resolves the contradiction by allowing durable sealing while preventing contamination, as the abrasion particles are indistinguishable from the original material.
Solution Approach 2:
The invention converts the harmful effect of abrasion into a beneficial outcome by ensuring that abrasion particles are made of the same material as the conveyed substance. What would normally be contamination is transformed into acceptable material particles, particularly valuable in recycling applications where material homogeneity is crucial.
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 approach prevents contamination of the conveyed material by ensuring that any abrasion is from the same material, maintaining the quality of the processed product, especially in recycling and dosing applications, and allowing for easy adaptation of sealing components to match the conveyed material.
Implementation Method 1
the friction of the sealing lips with the sealing surfaces can cause abrasion
Implementation Method 2
the friction of the sealing lips with the sealing surfaces can cause abrasion, which contaminates the conveyed material

AI summary
The method involves providing housing (3) in which to-be-conveyed goods (2) are conveyed with rotor blades (5) of a rotating cellular wheel (4). The sealing lips (6) of the rotor blades are abutted against the sealing surface of the housing. The sealing surface (7) or sealing lips which are made of an abrasive material that is contained in the to-be-conveyed goods are used during the transport of to-be-conveyed goods. The bristle or lamella structure is used as the sealing lips. An independent claim is included for rotary feeder.
