Gravity-Fed Dust Control for Bulk Material Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bulk material handling systems in the oil and gas industry generate significant dust emissions during the transfer of dry materials, leading to environmental issues and increased operational costs due to the need for additional personnel and equipment for dust collection and disposal.
Innovation Solution
A dust control system integrated with a portable support structure that uses gravity-fed outlets and vacuum systems to minimize dust emissions by controlling the flow of bulk materials from portable containers directly into blender units, eliminating the need for pneumatic or mechanical conveyance systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pneumatic or mechanical conveyance systems are used to transfer bulk material, then material transfer efficiency is improved, but dust emissions increase and additional equipment for dust collection is required
Solution Approach 1:
The patent removes the pneumatic or mechanical conveyance system from the material transfer process and replaces it with a gravity-fed direct discharge system. The container is positioned to allow bulk material to flow directly into the blender by gravity, eliminating the intermediate conveyance equipment that generates dust emissions.
Solution Approach 2:
The patent introduces a dust control system as an intermediary between the bulk material discharge point and the surrounding environment. This system captures and contains dust particles generated during material transfer, preventing their release into the atmosphere while allowing the simplified gravity-fed transfer method to be used.
2Productivity
If pneumatic or mechanical conveyance systems are used, then material flow control is improved, but system complexity and auxiliary power requirements increase
Solution Approach 1:
The patent extracts and removes the complex pneumatic or mechanical conveyance systems from the material handling process. Instead, it uses a simple gravity-fed discharge system where the container is positioned above the blender, allowing material to flow directly by gravity without requiring motors, pumps, or complex control mechanisms.
Solution Approach 2:
The patent positions the container and blender at appropriate elevations to create a gravity-driven flow path. The container is placed higher than the blender inlet, creating a potential energy difference that drives material flow without requiring additional power input or complex flow control systems.
3Object-affected harmful factors
If dust collection equipment is added to control emissions, then environmental compliance is improved, but operational costs and personnel requirements increase
Solution Approach 1:
The patent removes the need for extensive dust collection equipment by eliminating the dust-generating conveyance systems in the first place. The gravity-fed direct discharge method inherently produces minimal dust, reducing or eliminating the need for expensive dust collection and disposal infrastructure.
Solution Approach 2:
The simplified gravity-fed system is inherently lower-maintenance and requires less operational oversight compared to complex pneumatic or mechanical conveyance systems paired with dust collection equipment. The system essentially manages itself through gravity-driven flow without requiring additional personnel for equipment monitoring or dust disposal operations.

AI summary
Controlling the dust emissions from the discharge of bulk materials from a container provides many benefits. A container engages a support structure that includes a frame. The frame includes a dust control enclosure coupled to an outlet or a hopper at the top of the frame and the container or a discharge gate of the container. The dust control enclosure comprises a collapsible and flexible material so that a tight seal is formed between the container and the hopper or the outlet of the frame. Dust from the discharged of the bulk material from the container is contained within the support structure. A dust control panel may also be disposed at the top of the frame to prevent any dust from migrating through the frame. The container may comprise a plurality of dust enclosure panels to further prevent the escape of dust during discharge of the bulk material.
