Automatic Polymer Dosing & Feeding Machine

Automatic dosing machine, also known as automatic dosing machine, is used for automatic feeding of PAM or PAC in sludge dewatering machine or DAF air flotation machine system. The automatic dosing machine controlled by PLC does not require manual operation. It is a kind of equipment that can realize automatic dosing and dissolving of powder, preparation and delivery of pharmaceutical solutions.

Application

Widely used in water treatment, sewage treatment and other process media treatment in petroleum, chemical, paper, electric power, coal, pharmaceutical and food industries.

Working Princple

Working principle of automatic dosing machine The polymer powder is filled into the feed hopper through the screw conveyor at the bottom. The polymer is fed by a screw conveyor precisely controlled by a VFD motor. The water supply is controlled by solenoid valves and flow meters. Powder and water mixing occurs in a two-stage mixing chamber, and after the solution is stored in a storage tank, the liquid level is controlled by a level controller. A metering pump supplies the polymer solution to the sludge dewaterer or DAF unit. As metering progresses, polymer metering and mixing will restart when the liquid level drops to the set point.

Features

  • Compact unit, fully automatic batching and mixing controlled by PLC
  • For PAC and PAM dosing
  • Made of stainless steel 304
  • Two-stage chamber ensures uniform mixing
  • Includes vibrating motor in feed hopper to prevent polymer build-up
  • Includes feed hopper and screw conveyor heaters to keep polymer dry
