Principle:

The device is a continuous dosing system that can automatically configure the powder polymer flocculation agent.Dry powder flocculants go into the pre-mixer through the screw propeller to pre-mix with water, wetted material goes into a mixing tank for dilution to the required solution concentration;the prepared solution goes into the storage tank through the mixing tank and the curing tank,when the storage tank liquid level is at high level,the preparation process automatically stops,when the solution liquid level decreases to the middle level,the preparation process restarts.Mixers are equipped inside the mixing tank and the curing tank to ensure a full dilution and curing of the flocculant.When the system generates alarm,it proves a need to check and repair some part inside the system.The liquid flocculant is directly added into eh mixing tank by the screw pump.In the process of preparation,the amount of flocculant is constant while water is added according to the proportion or(the water amount is constant,flocculating agent is added according to the proportion).In order to ensure the solution concentration unchanged during the whole process,the prepared solution goes into the dosing pump trough the storage tank,then pumped into the flow meter by the dosing pump for inline dilution,and then into a pipeline mixer to realize the flocculation effect.Dosing device can be designed according to user's different processes requirements and configure necessary components to realize automatic remote control function etc.

Advantage:

1.High degree of automation,PLC control system,simple and convenient operation.

2.The system is stable and reliable,fault related equipment will stop automatically according to the requirements and give out sound and light alarm.

3.Using single screw feeder to dose powder,speed can be controlled to ensure uniformly and dispersion dosing.

4.Under the production volume required and continuous liquid dosing conditions,guarantee the curing time of the prepared solution at about 1 hour.The prepared concentration is of 0.1%-0.3%.

5.The box body is made of stainless steel material,good corrosion resistance and nice.

6.Using the three tank overflow type solution operations,which makes the equipment simple in structure,small volume,convenient in installation and applicable in the process of dissolving and continuous reagent addition.

7.The mixer adopts multilevel special paddle structure design.

8.The pre-mixer accelerates the powder hydration,the water flow can be adjustable.

9.The dry powder addition volume changes with the water flow to maintain a constant concentration.
