GDAT Type Automatic-operated Chemical Dosing System with Three Chambers

 

Introduction >>>

 GDAT three-chamber type automatic chemical dosing system is a flocculants dissolving and preparation system that can automatically and continuously work; for preparation of chemical solution of 0-5000 liter/h, the concentration is between 0.1% -0.3%.

 The dry powder flocculants are sent by the screw propeller into the dissolver where it will be premixed with the clean water; then the mixture solution is sent into the preparation tank to be agitated and diluted as per the specified concentration; during the preparation process, the water feeding rate shall be relatively stable as may be checked by the flow meter in order to ensure that the concentration of the prepared solution will keep unchanged during the whole working process.

 The prepared solution is sent from the preparation tank to the digestion tank and then to the storage tank; when the storage tank is at high level, the chemical preparation stops and will restart during the dosing of the chemical solution. When the solution level at the storage tank declines to the medium level, the chemical preparation system will be put back to operation automatically. Both preparation tank and digestion tank are furnished with agitators to ensure that the flocculants will be completely diluted and digested; in addition, the shortage of chemical solution in the storage tank will trigger the low level alarming system, in this case, all systems will stop with alarming. This equipment is featured with high level of automation, stable performance, reliable and easy operation etc;





Technical features >>>


1. High level of automation, easy and convenient operation;


2. Stable and reliable performance, all relevant equipments will stop with alarming signals automatically in the even of failure of the equipment;


3. Use of screw feeder to feed the powder chemicals, of which the speed may be manually adjusted in order to ensure that the chemicals may be uniformly and accurately fed inside;


4. Under the specified production capacity and continuous dosing of chemical solution, the preparation concentration ranges between 0.1% - 0.5%;


5. Alarming signals will be triggered in the event of insufficient dry chemical powder or not enough chemical solution;


6. Use of small-size vibrating motor to prevent the dry powder from caking in the silo;


7. The use of pre-mixer can accelerate the water dissolving of the powder chemical;
