An online automatic preparation and dosing equipment for pam solid medicament

Abstract

An online automatic preparation and dosing device for PAM solid medicament disclosed by the present invention has a solid screw feeder (10) connected to a frequency conversion adjustable solid screw feeder (11) fixed on the upper part of the prefabricated mixing box (1). Below the discharge port of the solid feeder, there is a feeder outlet feed mixer (14) connected to the prefabricated mixing box, and a water inlet solenoid valve (9) and water inlet pipe are connected to the water inlet pipe of the feeder outlet feed mixer. The flowmeter (6), the inlet end of the variable frequency adjustable screw pump (8) is connected to the discharge port of the solution storage tank, and the outlet is connected to an outlet flowmeter. The water inlet flowmeter, outlet flowmeter, and frequency conversion adjustable screw pump , the water inlet solenoid valve, the solid screw feeder, and the frequency conversion adjustable screw solid feeder are all connected to the PLC control system of the PLC frequency conversion control cabinet (16), and the filling amount is automatically adjusted by the instantaneous flow signal of the PAM agent fed back in real time by the outlet flowmeter and solid dosage. Improved the accuracy and reliability of PAM agent solution filling.

Description

Technical field [0001] The present invention is a pharmaceutical automatic formulation investment and addition equipment technology field, mainly involving an online automatic investment and addition equipment for PAM solid agent.It can be widely used in the water treatment system of environmental protection, chemical industry, oil refining and other production processes, and realize online automatic feeding, automatic remedies, automatic liquid distribution, and automatic injection of PAM solid agent. Background technique [0002] At present, in various water treatment processes, PAM needs to be added as a condenser, which mainly increases the flocculation and settlement effect of various insoluble particles in the water, and better remove the suspended particles in the water.Because the PAM aid agent itself is a solid granular, in the normal temperature environment, it is difficult to formulate the water solution in contact with the air in the air, and the normally prepared aqu...

AI Technical Summary

Problems solved by technology

By detecting the outlet flow signal of the PAM chemical solution online, the filling amount of the PAM chemical is automatically adjusted, and the filling amount of the PAM chemical solution is automatically adjusted online in real time according to the demand of the water treatment process pipeline, and the purpose of intelligent fixed ratio filling is realized. The external injection adopts frequency conversion to adjust the screw pump to solve the problem that the viscosity of the chemical solution is too high to easily block the metering pump, greatly improving the accuracy and reliability of PAM chemical solution filling, and reducing the pollution to the environment while fully improving the utilization rate of the chemical
