Solution Overview
Problem
Existing methods for producing bitumen blocks face challenges in accurately maintaining a predetermined filling quantity and weight, as well as the need for temperature-resistant containers and manual handling of bitumen, which complicates processing and storage.
Innovation Solution
A method involving forming bitumen droplets, solidifying them into lozenges on a revolving belt, filling these lozenges into sacks, and then pressing the sacks to form a compact bitumen mass, allowing for precise filling and shaping without requiring temperature-resistant sacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If soft bitumen is filled into drums or temperature-resistant bags in liquid state, then the bitumen can be contained and transported, but the containers do not melt and manual removal is required, increasing handling complexity
Solution Approach 1:
The invention changes the physical state parameter of bitumen from liquid to solid form through controlled cooling and solidification processes. Bitumen is extruded in a semi-solid state, formed into pellets, and then filled into bags in this solidified form, eliminating the need for temperature-resistant containers and manual handling of liquid bitumen.
Solution Approach 2:
The invention segments the bitumen mass into individual pellets or granules through extrusion and cutting mechanisms. This segmentation allows the bitumen to be filled into bags in discrete units, facilitating automated handling and eliminating the need for large-volume liquid filling operations.
2Manufacturing precision
If bitumen sheets are shrunk into bags, then the bags can be melted during processing, but the fill quantity cannot be precisely controlled
Solution Approach 1:
The invention performs preliminary action by pre-forming bitumen into standardized pellets with controlled weight and dimensions before filling. This pre-preparation enables precise fill quantity control while maintaining high processing speeds through automated filling mechanisms that can rapidly dispense a predetermined number of pellets into bags.
3Manufacturing precision
If bitumen is extruded and solidified into pellets, then precise fill quantity control is achieved, but additional processing steps are required
Solution Approach 1:
The invention merges multiple functions into integrated equipment: the extrusion system simultaneously forms and cuts pellets, the cooling system solidifies the bitumen while conveying it, and the filling system automatically dispenses precise quantities. This consolidation reduces the number of separate processing steps and equipment needed.
4Volume of stationary object
If standard bags are used instead of temperature-resistant bags, then storage space is reduced and handling is simplified, but the bags must be melted during processing
Solution Approach 1:
The invention changes the temperature parameter profile from maintaining high temperatures throughout storage and handling to using ambient temperature for storage with temperature application only during the final melting/processing stage. This allows standard bags to be used for storage and transport, reducing storage space requirements and simplifying handling.
