With the increasingly high demand on the water quality purification in water treatment, the compound flocculating agent has enjoyed popularity and become widely used. For the preparation and feed of polymeric organic flocculants. advanced foreign technologies are introduced and improvement and innovation have been made on the preparation and feed device. A new generation JY series equipment for polymeric flocculants is developed and widely used in industries such as sewage treatment, drinking water treatment, industrial wastewater treatment, papermaking and ore smelting, featuring accurate feeding and adding, high degree of automation and high medicament utilization efficiency.
Operating principle
JY series PAM automatic mixing and dosing device is mainly composed of the automatic rationing, feeding and adding dry powder feeding unit, the dry powder pre infiltration device, inlet and discharge pipe lines, box and liquid level measurement mixing equipment and automatic control unit.
JY series PAM automatic mixing and dosing device is an overall system unit which integrates the dry powder storage, feeding, infiltration, dissolution and ripening processes and a full-automatic equipment which can prepare high-molecular polymer solution in batches in a continuous manner. The device can facilitate the polymer to ripen and dissolve fully efficiently and conveniently and prevent the green polymer from being fed and added into the treatment system. PAM powder can be fed into the polymer dissolving box through the spiral powder feeder in fixed quantities. The powder will be mixed with water and stirred completely to dissolve into PAM solution of a concentration of 0.1 -0.5%, after which the solution will enter the polymer storage box for further use through the ripening process.
The concentration of the solution to be prepared can be set beforehand within the range 0.05%-10%, but the solution viscosity of the chemicals prepared cannot exceed 2000mpas.
The curing time needed in the solution preparation depends on the extraction flow of the external dosing pump and the valid volume of the equipment. To guarantee the dissolution and curing of the solution, a period of 45 to 60 minutes should be ensured for the dissolution and curing, making sure the pesticide effect 丨r» full force.
Let the water in as set and add dry powder in fixed quantities automatically. The powder gets soaked in the preinfiltration device and enters the polymer dissolving tank to be stirred and resolve. When the liquid level rises to the overflow height, it will enter the curing tank and get stirred. When the liquid level rises to the overflow height, it enters the storage tank and gets stirred. When the liquid level rises to the highest point, the prepared PAM solution can be used.

Note:Dosage is the dry powder weight that is fed and added every bour when the dry powder adding spiral is at the minimum rotating speed-the mmaximum rotating speed.
When in real operation,the revolving speed of polymer adding spiral can be adjusted to adjust the dosage of dry powder and the intake pressure (rate of flow) can be adjusted according to the concentration requirements to satisfy the concentration and productivity requirements.
On special occasions,the revolving speed of the dry powder dosage spiral can be increased to make the addition of polymer every hour bigger.This should be put forward when ordering goods.
