Dosing Device for Dust-Free Chemical Introduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices face challenges in evenly distributing powder form chemicals like activated carbon or calcium hypochlorite into liquid media, as they often clog lines and generate dust when handled, due to their granular form and lime content.
Innovation Solution
A device with a receiving device that attaches to the chemical container, featuring a tilting receptacle and a ball valve for dust-free introduction of the chemical into the liquid medium, along with optional agitators for turbulent mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If powder form chemicals are handled openly for dosing, then the chemical can be introduced into the liquid medium, but dust development occurs and lines may become clogged
Solution Approach 1:
The patent employs a flexible hose with a nozzle system that creates a water seal barrier. The hose is inserted into the chemical container, and pressurized water flows through the hose to create a sealed pathway that prevents dust from escaping into the environment while allowing chemical transfer.
Solution Approach 2:
The invention uses hydraulic pressure from the liquid medium to drive the dosing process. Pressurized water flows through the flexible hose and exits through a nozzle to create a water seal, utilizing fluid dynamics to prevent dust generation while enabling chemical transfer from the source container to the liquid medium.
2Reliability
If granular chemicals with lime content are used, then the chemical can be stored and handled, but the lines become clogged and dosing becomes difficult
Solution Approach 1:
The patent replaces complex mechanical dosing mechanisms with a simple hydraulic-driven system. Instead of using mechanical pumps, valves, or conveyors to handle the granular chemical, the system uses the flow of pressurized water itself to transport the chemical through the flexible hose, significantly simplifying the dosing system while maintaining reliability.
Solution Approach 2:
The invention changes the physical state and flow parameters of the chemical by suspending the granular material in pressurized water flow. This transforms the handling from dry granular material (prone to clogging) to a slurry flow that can be easily transported through the flexible hose without clogging, while the turbulent flow at the nozzle ensures complete emptying.
3Productivity
If the container is tilted for emptying, then complete emptying can be achieved, but dust may be generated during the tilting process
Solution Approach 1:
The system uses hydraulic pressure from the liquid medium to drive the chemical out of the container through the flexible hose. The pressurized water flow creates a sealed pathway that prevents dust generation during the emptying process, while the continuous flow ensures complete emptying of the container without manual tilting.
Solution Approach 2:
The flexible hose filled with pressurized water acts as an intermediary medium between the chemical container and the liquid medium. This water-filled hose creates a sealed barrier that prevents dust from escaping during the transfer process, while still allowing complete emptying of the chemical through the controlled water flow.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables simple, clog-free, and dust-free dosing of chemicals into liquid media, ensuring complete emptying and uniform distribution, enhancing operational safety and efficiency.
Implementation Method 1
The closing element is a ball valve with connections for the container and for the container. The ball valve can be attached to the container and container when it is closed, then opening it allows the contents of the container to be introduced into the container 1.
Implementation Method 2
The approach element provided according to the invention comprises a tilting receptacle for the container. The container can be placed in the receiving device, then it can be tilted in the direction of the container using the tilting device. The container is placed upside down so that it can be emptied completely.
Implementation Method 3
For a further development of the invention, it is provided that at least one agitator is arranged in the container. This agitator is preferably in operation without interruption, it agitates the supplied chemicals in the medium. The container preferably has an approximately cuboid shape, as a result of which turbulent flow conditions are formed in the container.
