The invention has the beneficial effects as follows:
The present invention washes equipment for the automatic medicine of water treatment system and efficiently solves water treatment system medicine and wash security risk and the complex operation that operating process preparating liquid may bring, the problem that is prone to accident.In the time that water treatment system needs medicine to wash, system automatic-prompting, only need press a key and confirm, can carry out medicine and wash, medicine rinses after washing end automatically repeatedly, after the instrumentation monitoring flushing water of pipeline is up to standard, the medicine work of washing stops, and whole process operation is simple, safety, operating efficiency significantly improves, equipment is washed process at medicine, only needs to confirm the whole industrial computer programme-control of whole process, automatically complete, effectively reduce to cause because of artificial origin the risk of fault.
Accompanying drawing explanation
To be the present invention wash equipment Chinese medicine for the automatic medicine of water treatment system to Fig. 1 washes the structural representation of part;
Fig. 2 is the present invention washes equipment control section structural representation for the automatic medicine of water treatment system.
Wherein:
1 industrial computer 2 PLC switch boards
3 medicine groove 4 measuring pumps
5 medicine washing trough 6 I centrifugal pumps
7 bag filter 8 pneumatic operated valves
9 milipore filters or reverse osmosis membrane 10 magnetic valves
11 tank 12 II centrifugal pumps.
The specific embodiment
In conjunction with the accompanying drawings and embodiments the present invention being washed to equipment for the automatic medicine of water treatment system below, is elaborated:
As Fig. 1, shown in 2, a kind of automatic medicine for water treatment system is washed equipment, comprise medicine groove 3, the liquid outlet of medicine groove 3 is communicated with the entrance of measuring pump 4 by pipeline, the outlet of measuring pump 4 is communicated with the entrance of medicine washing trough 5 by pipeline, the outlet of medicine washing trough 5 is communicated with the entrance of I centrifugal pump 6 by pipeline, I number centrifugal delivery side of pump is communicated with the entrance of bag filter 7 by pipeline, the outlet of filter 7 is communicated with the entrance of milipore filter or reverse osmosis membrane 9 by pipeline and pneumatic operated valve 8, milipore filter or reverse osmosis membrane 9 export by pipeline and magnetic valve 10 and are communicated with the entrance of medicine washing trough 5.
The delivery port of tank 11 is communicated with the entrance of II centrifugal pump 12 by pipeline, and the outlet of II centrifugal pump 12 is communicated with the entrance of medicine washing trough 5 by pipeline.
Sensor in each equipment in water treatment system, as the signal output of pressure sensor, flow sensor, conductivity sensor and pH sensor (not shown) is connected with the input of industrial computer 1 respectively, the output of industrial computer 1 is connected with the input of PLC switch board 2 respectively, and the control signal of PLC switch board 2 is connected with the signal input part of measuring pump 4, I centrifugal pump 6, pneumatic operated valve 8, magnetic valve 10 and II centrifugal pump 12 respectively.
Operation principle of the present invention:
The parameter of the various settings in industrial computer 1 in pre-stored water treatment system, as pressure, flow, electrical conductivity and pH value etc.In the time of system works, the on-line parameter of the various sensors on equipment, as pressure sensor, flow sensor, conductivity sensor and pH sensor are input in industrial computer 1, industrial computer 1 compares the parameter of on-line parameter and setting, again comparative result is transferred to PLC switch board 2, PLC switch board 2 is assigned instruction to each electric units processed as magnetic valve, pneumatic operated valve, the pump housing etc., controls each electric units action processed, the object of washing to reach medicine.
Concrete using method of the present invention:
(I) is when milipore filter or reverse osmosis membrane 9 intake pressures exceed capping or aquifer yield is prescribed a time limit lower than under setting, pressure sensor or flow sensor by and industrial computer 1 between incoming line parameter signals, industrial computer 1 is received and is transmitted medicine by the input circuit of PLC switch board 2 to PLC switch board 2 after signal and wash signal, and the touch-screen of PLC switch board 2 there will be dialog box prompting whether to carry out medicine to wash work;
(II) selects "Yes", and PLC switch board 2 is the electrical part signal transmission to pipeline by output loop, and equipment automatically carries out medicine and washes state.Measuring pump 4 is worked, and the liquid in medicine groove 3 enters in medicine washing trough 5, and II centrifugal pump 12 is worked simultaneously, and the running water in tank 11 also enters in medicine washing trough 5 by pipeline;
(III), when medicine washing trough 5 herb liquid concentration reach medicine while washing required concentration, measuring pump 4 quits work; I centrifugal pump 6 is worked, and pneumatic operated valve 8, magnetic valve 10 on pipeline are opened, and liquid enters milipore filter or reverse osmosis membrane 9 through bag filter 7 and pipeline, by flowing back to medicine washing trough 5 after milipore filter or reverse osmosis membrane 9, so repeatedly it is carried out to medicine and washes;
(IV) medicine is washed after end, and I centrifugal pump 6 quits work, and pneumatic operated valve 8, magnetic valve 10 are closed, and stop supplying with liquid.Running water in tank 11 enters medicine washing trough 5 by pipeline, reach after liquid level, pneumatic operated valve 8, magnetic valve 10 are opened, running water in tank 11 is by bag filter 7 and pipeline, enter milipore filter or reverse osmosis membrane 9, it is rinsed, and flushing water finally flows back to medicine washing trough 5, repeatedly milipore filter or reverse osmosis membrane 9 is rinsed;
(V) rinsed and reached after set point number, and dialog box appears in touch-screen, and whether lifting medicine is washed work and finished, and selects "Yes", and medicine is washed end;
(VI) whole medicine is washed process and is carried out complete monitoring by the display screen of computer industrial computer 1.
Automaticity of the present invention is high, simple to operate, whole process only need be pressed a key and confirmed, has effectively reduced artificial origin simultaneously and cause the risk of fault.
