Problem Statement
- Generally, in many applications, there is an indeed requirement of controlled flow of molten liquid materials.
- In the prior arts, the motors/regulators/ other media had discussed for controlling fluid flow.
- In essence of prior arts literature survey, there is no separate device for precise control of molten liquid and cold liquids, including control of molten liquid at low flow rates.
- Another issue stated that the solidification of the molten liquid due to cooling below the melting point. Hence, the present patent provides the solution to address the issues.
Technology
- Present invention describes about a device for controlling flow of a molten liquid at a precise low flow rates, wherein maximum flowrate can be achieved is equal to the natural flow rate of the liquid, when it is not controlled.
- The device includes following elements as listed in below:
- A metal container with top and bottom nozzles with an on-off valves, wherein said container is partially filled with molten fluid & partially with air, & said nozzle and non-conducting pipe are filled with air ;
- A syringe or any airtight pump wherein syringe discharges said air into the metal container;
- A non conducting pipe to connect the syringe with metal container, and air released displaces the molten metal where the flow of air from the syringe pump controls the flow of molten liquid.
- The usage of a syringe pump helps to achieve very low rate with precision.
- The flow of air from the syringe pump controls the flow of molten liquid.
- Said device controls the flow of molten fluids, cold fluids and any other fluids, where control flow rates are required.
- Entire device is kept airtight together with the syringe pump.
Key Features/Value Proposition
Technical Perspective:
- The device can control the flow rate of molten fluid to avoid solidification of the molten liquid inside the device.
- The device can control the flow rate of molten fluids and cold fluids and any other fluids, wherein the controlled flow rates are required.
Industrial Perspective:
- Patent literature used to control the flow-rates of corrosive chemicals since it minimizes the exposure of the liquid to the surfaces.
