Motor-Driven Crusher Disc Screen Separator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for separating smaller material from larger material in excavation processes require multiple pieces of equipment, are time-consuming, and are hindered by debris accumulation, which complicates the functionality of separating devices like roller screens.
Innovation Solution
A motor-driven crusher and mechanical bucket system with a disc assembly and scraper device that allows for efficient separation of smaller material from larger material using a single piece of equipment, featuring a disc assembly with rollers and chains that rotate at variable speeds to agitate and separate materials, and a scraper mechanism to remove debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple pieces of equipment are used for material separation (vehicle for collection, separating device, vehicles for delivery), then material separation can be performed, but the process becomes time-consuming and complex
Solution Approach 1:
The patent combines the collection function and separation function into a single mechanical bucket assembly. The bucket includes a disc screen separator integrated within it, allowing material to be collected and separated in one operation rather than requiring separate collection and separation equipment. This merging eliminates the need for multiple vehicles and intermediate transfer operations.
Solution Approach 2:
The mechanical bucket is designed to perform multiple functions: it collects material, separates material by size through the disc screen, and can deliver both smaller and larger materials simultaneously. This multi-functional design replaces the need for specialized equipment for each function, reducing overall system complexity and improving productivity.
2Productivity
If roller screen separators are used with close roller shafts and small screening areas, then separation can be performed, but debris collects and lodges in the components, hindering proper functionality
Solution Approach 1:
The disc screen separator uses multiple discs arranged in a segmented pattern around a central axis. This segmentation creates numerous small screening surfaces distributed throughout the bucket, preventing debris from concentrating in single locations. The segmented design allows material to be separated across multiple surfaces rather than one large area, reducing debris lodging issues.
Solution Approach 2:
The disc screen separator incorporates vibration mechanisms that cause the discs to vibrate during operation. This vibration prevents debris from collecting and lodging on the screening surfaces by continuously moving material across the discs. The mechanical vibration maintains reliable separation functionality by preventing the debris accumulation that would otherwise hinder proper operation.
3Adaptability or versatility
If disc screen separators with multiple discs are used, then separation of smaller material can be achieved, but the screening spaces are very small and limited to certain applications
Solution Approach 1:
The disc screen separator utilizes three-dimensional space by arranging multiple discs vertically and radially around a central axis. This dimensional arrangement creates numerous screening spaces in different orientations and locations within the bucket, effectively increasing the total screening area available. The multi-dimensional configuration allows the separator to handle a wider range of material sizes while maintaining adequate screening surface area.
