Biosolid Spreader with Conveyor and Carbon Filter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manure spreaders are not suitable for distributing biosolid materials as they generate a significant amount of unpleasant aerosol powder, requiring additional steps for burial to reduce odor emissions, increasing distribution time and energy consumption.
Innovation Solution
A vehicle with a spreader system featuring rotating augers and hoes that pick and convey biosolid material vertically, allowing for controlled release near or below the ground surface, reducing aerosol formation and odor, and incorporating an active carbon filter to neutralize odors, while optimizing energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rotating discs are used to crush and eject manure at a distance, then the manure spreading efficiency is improved, but biosolid materials are atomized generating unpleasant smell aerosol
Solution Approach 1:
The invention changes the operational parameters by using a conveyor belt system that operates at lower speeds and with different mechanical action (conveying rather than crushing), thereby preventing aerosolization while maintaining spreading capability
Solution Approach 2:
The invention replaces the rotating disc mechanical system with a conveyor belt system, fundamentally changing the mechanism from high-velocity crushing and ejection to controlled conveying and deposition, eliminating the harmful aerosol generation
2Object-generated harmful factors
If further operation to bury the biosolid is carried out to reduce smell emission, then odor control is improved, but the timing of distribution increases considerably
Solution Approach 1:
The invention merges the spreading and burial operations into a single integrated process by using the conveyor belt to deposit biosolids directly into furrows created by the vehicle, eliminating the need for separate burial operations
Solution Approach 2:
The invention performs preliminary action by creating furrows before deposition and simultaneously completing both spreading and burial in one pass, preventing the need for subsequent burial operations
3Area of stationary object
If rotating discs are used for long-distance crushing and launching, then spreading coverage is improved, but aerosolization and energy consumption increase
Solution Approach 1:
The invention replaces the energy-intensive rotating disc system with a conveyor belt system that uses significantly less energy, achieving comparable or superior spreading coverage through controlled deposition rather than high-velocity ejection

AI summary
A vehicle (1) for the distribution of biosolid material comprises a body (2) suitable for containing the biosolid material and suitable for being transported on agricultural land (T). The vehicle further comprises a spreader (3) supported on at least one of the sides (21, 22) of the body. The spreader comprises picking means (31) of the biosolid material from the box, conveying means (32) of the biosolid material from the picking means (31) towards an outlet mouth (320) in the land. Member actuating means (4) are adapted to move the conveying means (32) from a retracted position, in which the outlet mouth is spaced above the surface of the land, to an advanced position, in which the outlet mouth is adapted to be buried in the ground at a given depth (D) or just above the surface of the land. A method of distributing biosolid material involves discharging the biosolid material at ground level or into the ground.
