Automatic medicine washing equipment for water treatment system

Abstract

The invention discloses automatic medicine washing equipment for a water treatment system. The automatic medicine washing equipment comprises an industrial personal computer, a PLC (Programmable Logic Controller) control cabinet, and a medicine groove and a medicine washing groove which are communicated with each other by a pipeline and a metering pump, wherein the medicine washing groove is also communicated with a water groove by a pipeline and a centrifugal pump; an outlet of the medicine washing groove is communicated with an inlet of a bag type filter by a pipeline and a centrifugal pump; the outlet of the filter is communicated with the inlet of an ultra-filtration membrane or a reverse osmosis membrane by a pipeline; the outlet of the ultra-filtration membrane or the reverse osmosis membrane is communicated with the inlet of the medicine washing groove by a pipeline; the industrial personal computer is connected with a sensor of each set of equipment by a circuit; the PLC control cabinet is connected with a NO.I centrifugal pump, a NO.II centrifugal pump, a pneumatic valve and a solenoid valve respectively. With the adoption of the automatic medicine washing equipment for the water treatment system disclosed by the invention, a whole medicine washing process is controlled by an industrial personal computer program and is automatically finished; operation carried out by workers is not needed and the risk of causing faults due to manmade reasons is effectively reduced.

Description

technical field [0001] The invention belongs to a device for cleaning a water treatment system, in particular to an automatic medicine washing device for the water treatment system. Background technique [0002] After the water treatment system has been in operation for a period of time, the ultrafiltration membrane and reverse osmosis membrane will be clogged, resulting in an increase in pressure drop and a decrease in flow rate, which will affect the shortage of production water. Therefore, it is necessary to regularly clean the ultrafiltration and reverse osmosis membrane with drugs to ensure production. Purified water required. [0003] The medicine washing operation of the existing equipment is all manually operated. First, the medicine liquid is prepared manually. According to the volume of the medicine tank, the thickness, length and quantity of the film, the amount of the medicine liquid to be used is calculated, and then poured into the medicine tank. Flowchart of ...

AI Technical Summary

Problems solved by technology

[0005] The liquid medicine required for medicinal washing is strong acid and strong alkali. Operators need to be trained in safe operation and emergency treatment. Two people are required to operate. Even so, there is no guarantee that there will be no accidents. personal injury

[0006] 2. The operation is cumbersome and prone to accidents

In case of misoperation: wrong opening and closing of the valve, or forgetting to open and close a certain valve, the medicine washing work will not only cause serious damage to the equipment, but also cause heavy losses

At the same time, the quality of pure water used in production will also be seriously unqualified, and the products produced will also have serious quality problems
