The automatic flocculant preparation system(dosing system
Overview: The automatic flocculant preparation system(dosing system) is made according to the characteristics of high polymer medicament, which is difficult to dissolve, easy to agglomerate and easy to condense after long-term exposure to air. It solves the problems of using conventional simple dissolving medicament, such as waste of manpower, inaccurate dosage, uneven dosage and solid matter. The full-automatic flocculant preparation system is an intelligent, full-automatic and continuous integrated flocculant solution and dosing device. The range of preparation solution is 0-6000 L / h, and the concentration is 0.1% - 0.5%. Working principle: The dry powder flocculant enters the premixer from the screw propeller for premixing with clean water, and the wetted materials enter the preparation tank for dilution, and the preparation is conducted according to the required concentration; if it is liquid flocculant, it is directly put into the preparation tank by the screw pump. In the process of preparation, if the water volume changes, the flocculant dosing device will automatically follow the change of water flow, so as to ensure that the concentration of the prepared solution will not change during the whole working process. The dosage of water and solid dry powder must be adjusted to the same proportion as the output of the dosing pump, otherwise the dosage reserve supply will be insufficient or the liquid will overflow. The preparation solution enters the storage tank from the preparation tank through the maturing tank. When the liquid level in the storage tank is at a high level, the preparation process will stop automatically. When the solution drops to the medium level, the batching process will be restarted automatically. The mixing tank and the maturing tank are equipped with spiral blade agitators to fully ensure the dilution and maturing of the flocculant. In addition, the liquid level signal under the storage tank can be used to control the start and stop of the secondary dilution and dosing process. In the first use, when the water from the three dosing tanks is injected to 2 / 3 of the tank, the solid dry powder feeding device shall be opened again. After adjusting to a certain proportion, water shall be added and solid dry powder shall be added at the same time. At this time, the mixing motor and return water pump of each tank shall be opened to dilute the liquid in the three tanks evenly.
Product features: 1. Adopt intelligent instrument full-automatic control, full-automatic operation, save labor 2. Anti corrosive engineering plastics and stainless steel shall be used for the part contacting with the medium, with good anti-corrosion performance; 3. The solid agent is accurately added by the dry powder feeder, and the dosage can be adjusted accurately to ensure the stable ratio of the agent; 4. The control box shall be set with fault alarm, and make actions such as alarm, automatic manual switch, single machine stop and system stop according to different situations to ensure the safe operation of the equipment; 5. The whole set of equipment adopts three tank overflow solution operation system, which makes the equipment simple in structure, small in volume and convenient in installation. It is suitable for dissolving and continuously adding reagents. 6. The system adopts multiple boxes to ensure complete dispersion and aging. Application scope: 1. Wastewater treatment: flocculation treatment of urban or industrial wastewater, treatment of sludge dewatering process, and tertiary or quaternary treatment of municipal wastewater; 2. Drinking water treatment: water plant using surface water as water source, as the dosing system of water purification agent and flocculant; 3. Process dosing: food, beverage, pharmaceutical industry, chemical industry, petroleum, pulp and paper industry; 4. Other industries: electroplating, food and beverage industry wastewater treatment, chemical industry, petroleum, pulp and paper industry wastewater treatment, ore smelting industry wastewater treatment. The device is composed of water supply system, dry powder feeding system, dissolving and maturing system, control system, liquid feeding system and secondary dilution feeding system. Models:
