core advantage
Factory skid mount, plug and playAdopting integrated structural design, the metering pump, dissolving tank, mixer, pipeline valve and control cabinet are fixed on the stainless steel base (skid block) as a whole, and the site can be put into operation only by connecting the pipeline and power supply, shortening the construction period 80% Above.
Precise measurement, saving medicineEquipped with high-precision diaphragm/plunger metering pump, combined with frequency conversion speed regulation and online monitoring system (pH/ORP/residual chlorine/conductivity, etc.), to achieve automatic quantitative dosing on demand and improve the utilization rate of chemicals 15%–30%。
Highly automated and unattended: Support PLC intelligent control, with automatic dispensing, continuous drug dissolution, high and low liquid level chain protection, dry powder/liquid automatic replenishment and automatic fault alarm functions.
Compact structure, safety and corrosion protectionThe pipes and tanks are made of high-corrosion-resistant materials (UPVC, PVDF, 316L, PE, etc.) according to the characteristics of the agent, which covers a small area and completely eliminates the leakage of the agent.
Workflow and principle
According to the dosage form (dry powder or liquid), the system realizes automated preparation and high-precision dosage:
Process diagram:
[Dispensing stage] dry powder/concentrate + tap water; automatic metering of water inlet/feed; multi-stage stirring to dissolve medicine; curing/storage;
[Dosing stage] Drug liquid tank → online instrument feedback adjustment (PLC) → high-precision metering pump → dosing point
Automatic dissolving/dispensingIn the dissolving tank, the medicine and water are mixed according to the set ratio by precise measurement, and the electric mixer is turned on to dissolve and mature quickly and evenly.
Closed-loop metering: The prepared liquid medicine is precisely transported to the dosing point through the metering pump.
feedback adjustmentOnline monitoring instruments detect water quality parameters (such as pH, turbidity, residual chlorine), feed back signals to the PLC controller in real time, and automatically adjust the stroke or frequency conversion speed of the metering pump to ensure that the dosage is dynamically matched with the water quality.
