Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for heating grain bins lack efficient and cost-effective solutions for directing heated air into the bin, leading to potential overheating, over-drying, and operating inefficiencies, particularly when using construction heaters with existing unheated grain bins.
Innovation Solution
A multi-outlet heater system with a flexible duct connection and adapter device that allows for selective connection of flexible ducts to the heater, featuring a front end with inlets for heated air and an outlet end designed to fit over the grain bin aeration fan intake, along with an optional sizing adapter for compatibility with various fan sizes, enabling controlled ambient air intake to supplement heated air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If construction heaters are used to heat grain bins without proper air direction control, then heated air can be added to the bin, but overheating and over-drying may occur leading to operating inefficiencies
Solution Approach 1:
The adapter device serves as an intermediary component between the construction heater and the grain bin aeration fan. It includes a housing with a heater interface that receives heated air from the heater, and a fan interface that couples to the fan intake. The adapter directs the heated air into the fan intake while allowing ambient air to be drawn in through the housing, creating a controlled mixture before delivery to the grain bin. This intermediary structure prevents direct uncontrolled heating and enables efficient drying operation.
2Temperature
If construction heaters are operated in continuous heating mode to ensure adequate heating, then sufficient heat is provided, but excessive fuel is consumed
Solution Approach 1:
The adapter device changes the parameters of the air stream by mixing heated air from the construction heater with ambient air drawn through the housing. This allows the system to operate at lower heater temperatures and reduce fuel consumption while still achieving adequate drying conditions in the grain bin. The mixing process occurs within the adapter housing, creating a controlled temperature profile that is more energy-efficient than continuous high-temperature heating.
3Quantity of substance
If a box is constructed over the fan to mix heated air with ambient air, then air mixing is achieved, but the system lacks control over drying conditions and causes overheating
Solution Approach 1:
The adapter device segments the air intake function into distinct pathways: one for heated air from the construction heater through the heater interface, and another for ambient air through the housing. This segmentation allows independent control and measurement of each air stream, enabling precise control over the mixing ratio and resulting drying conditions. The structured segmentation replaces the uncontrolled mixing in a simple box construction.
4Ease of manufacture
If flexible ducts are directly connected to single-outlet heaters, then simple connection is achieved, but compatibility with multi-outlet heaters and various fan sizes is limited
Solution Approach 1:
The adapter device is designed with universal compatibility features: the heater interface can accommodate multi-outlet construction heaters with multiple flexible duct connections, and the fan interface is designed to couple with various grain bin aeration fan intake sizes. This multi-functional design allows a single adapter model to work with different heater configurations and fan types, greatly enhancing versatility while maintaining simple flexible duct connections.

AI summary
An apparatus for connecting a heater to a grain bin aeration fan features a multi-piece adapter device having a connection adapter with inlets for receiving flexible ducts from a heater. The connection adapter can be used on its own to directly interface with a grain bin aeration fan of a first size, or can be used in combination with a cooperative sizing adapter to adjust an effective outlet size of the adapter to better fit a grain bin aeration fan of a different second size. An ambient air intake in the connection adapter entrains ambient air into the heated air stream.
