PAM dosing device fully automatic dosing

The PAM fully automatic dosing device is mainly used to prepare PAM polymer flocculant solution, which is a device that converts powdered PAM into liquid. The equipment mainly consists of a PAM powder feeding device, a rapid dissolution device, a three tank dissolution tank, a dissolution mixer, an inlet control device, a liquid level control device, a PLC electronic control system, an overflow venting pipeline, and a dosing pump.

　　PAM powder feeding deviceThe powder is placed in the medicine box and conveyed through the spiral conveyor at the bottom. The frequency conversion control of the conveyor can accurately control the size of the dosage. The discharge port is equipped with a heating device to prevent the powder from absorbing moisture and clumping, which can block the discharge port. Install a vibration device on the medicine warehouse to solve the problem of inaccurate powder dosage caused by PAM powder being placed overhead.

　　Rapid dissolution deviceThis device is a device for rapid contact between powder and water, which uses hydraulic action to quickly stir and dissolve the powder, preventing powder agglomeration and difficult dissolution.

　　Three slot dissolving medicine boxPAM dissolution is divided into three stages of dissolution, with each stage overflowing to improve the dissolution efficiency of the drug.

　　Dissolving mixerThe mixer adopts multi-stage variable speed, divided into high, medium and low speeds, to improve the dissolution rate of the polymer agent without damaging the molecular chain of the agent.

　　Water inlet control deviceDetect the amount and pressure of incoming water. Chain control of dry powder dosage.

　　Liquid level control deviceDetect the liquid level of the medicine box and control the equipment to automatically start and stop.

　　PLC electrical control systemControl the automatic start or stop of all electrical components.

　　Overflow vent pipeLong term shutdown of equipment, emptying equipment for use.

　　Dosing pumpAdd medication to the supply point.

Process Principle

Due to the requirements of water treatment technology The pH value of water often needs to be controlled within an irregular range, and manually adding acid or alkali to the water is a direct method to meet this requirement.

Common acid and alkali neutralizing agents include sulfuric acid, hydrochloric acid, calcium hydroxide, sodium carbonate, and so on.

Process Overview

It mainly includes the drug solution preparation system, metering and dosing system, safety system, and control system.

Add solid medicine into the dissolving tank Then add industrial water in proportion and stir to dissolve, and use the metering and dosing system to add chemicals to the dosing point. The dosing control can be done manually or automatically based on the control signal output by the upper system.
