Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a sulfuric acid metering device with precise measurement. Background Art

[0002] Sulfuric acid is an important raw material in chemical production. Sulfuric acid metering tanks are generally used in production to measure its dosage to ensure production accuracy requirements and avoid raw material waste.

[0003] For example, Chinese patent CN216582080U discloses a sulfuric acid tank that can accurately measure. When sulfuric acid needs to be added to the metering tank, the water pump can be started to allow the sulfuric acid inside the storage box to enter the connecting pipe through the bottom pipe, and then enter the metering tank through the liquid inlet pipe to complete the filling of the sulfuric acid. There is no need for personnel to fill it manually, which avoids sulfuric acid splashing on people. However, when replacing the storage box, the residual sulfuric acid on the surface of the bottom pipe will cause it to drip onto the base. When replacing the storage box, the staff may accidentally touch it and contaminate the skin of the staff, causing the skin to be corroded by sulfuric acid. Therefore, we propose a sulfuric acid metering device with accurate measurement. Utility Model Content

Then the weighing platform can measure and weigh the sulfuric acid in the metering tank. The liquid supply component is rotatably connected to the connecting horizontal plate and can be rotatably provided with sulfuric acid for the liquid inlet component continuously. During continuous feeding, the driving component drives the liquid inlet component to continuously extract sulfuric acid from the liquid supply component. When the liquid inlet component moves up and down, the sulfuric acid remaining at the end of the liquid inlet component will be recovered by the recovery component and returned to the liquid supply component, thereby avoiding waste of sulfuric acid raw materials and preventing sulfuric acid residue on the device from being accidentally touched by staff, which is safer.
