Product Details:

The high - molecular - weight automatic dissolving and dosing unit is used for preparing and dosing high - molecular - weight organic coagulants. It can automatically feed, dissolve, age, store, meter, and dose.

Workflow:

Used in wastewater treatment, this machine effectively and continuously mixes compounds to form reactive polymer solutions. Its main components include a polymer feeder (with a hopper), a dry powder penetration unit, a tank, a level controller, a mixer, a dosing feed pipe, and an electrical control panel. Here are some key parts:

Polymer Dissolving Unit: Comprising a pre - soaking device, tank, and 3 agitators. The pre - soaking device pre - wets and mixes polymer powder. The three tanks are for pre - mixing, homogenizing and aging, and storing. Each has a corresponding agitator to ensure homogeneity.

Polymer Metering Unit: Made up of a hopper, a feeding screw, and an electric heater. The hopper's effective volume meets long - term feeding needs and has a sight glass to monitor the dry powder level. The high - precision reducer - driven feeding screw controls the feeding rate. The electric heater, installed in the feeding screw's discharge pipe, prevents powder caking.

Water Supply Unit: Consists of pipes, a manual ball valve, a filter, a pressure gauge, a solenoid valve, a globe valve, and a rotameter.

Features:

The polymer auto - foaming machine mainly uses dry powder. From powder to solution, the entire process is dynamic, safe, and continuous. Dry powder from the funnel enters the mixer, gets wetted, and flows into the mixing tank to be diluted to the desired concentration. The diluted solution then goes through the solidification treatment tank and into the storage tank. When the solution level is low, the level switch signal activates the equipment to restart the solution preparation process.

The controller calculates the required powder feed rate based on the desired solution concentration. When the tank is full, the cycle stops; if empty, it restarts. This enables continuous system operation with the mixer continuously blending dry powder.
