Working principle of automatic dosing machine

　　Automatic dosing machineAccording to the required drug concentration, configure it in the mixing box, stir it with the mixer and put it into the solution box, and use the metering pump to transport the prepared solution to the specific system at the dosing point. The actual working principle is summarized as follows:

1. Use vaporized solvent, connect the air pipe to the bottom of the solid-liquid isolation plate, and use the air compressor or fan above as the air source.

2. After the gas enters the solvent tank, an air cushion layer is generated at the bottom of the isolation plate. When the air cushion layer reaches a certain thickness, the gas is released from the filter cap gap at high speed and directly impacts the solid coagulant on the isolation plate, violently. Stirring promotes collision and crushing of coagulant particles and rapid dissolution in water.

3. After the air flushing of the automatic dosing machine is terminated, the melted medicinal liquid enters the lower liquid storage tank through the discharge pipe for storage. At the same time, the solid particles are blocked by the filter cap on the liquid isolation plate, and the medicinal residue can be discharged on time. .

4. The liquid in the liquid storage tank is sent to the mixing reaction tank by the matching metering pump.

The automatic dosing machine can also carry out purposeful design according to the needs of different production processes of customers, configure essential components, and realize automatic remote control and other services.

The dosing equipment has excellent solvent corrosion resistance. The microporous tube is resistant to various acids, alkalis, salts and most organic solutions. It is non-toxic, odorless, and has no foreign matter dissolution. It is suitable for major purposes such as medicine, food, chemical industry, and environmental protection. .Do you know what are the common methods of dosing equipment?

1. Chemical water replenishment and condensate ammonia adding system. The ammonia adding system can realize fully automatic control; in addition to manual preparation, the preparation of ammonia liquid can also be automatically controlled. When the liquid level in the solution tank is less than the preset value, the solution tank water valve will be automatically opened. It automatically shuts down when there is no upper liquid level. In addition to manual control, the ammonia adding amount can also be controlled automatically. After the PLC program control system performs PID calculation, the frequency converter controls the ammonia adding amount of the ammonia dosing pump to achieve the effect of fully automatic dosing. .

2. For the preparation of phosphate solution in the boiler water phosphorus-adding salt-mixing system, add sodium phosphate directly to the dosing point of the solution box, start the automatic dosing machine and mixer to melt, and the amount of phosphate added can be controlled in addition to manual control. Fully automatic control, after PLC program control system performs PID calculation, the frequency converter controls the amount of phosphorus dosing pump to achieve automatic dosing effect.
