Embodiment
A kind of automatic medicament feeding system of the present utility model, comprises pneumatic diaphragm pump 6, medicament storage tank 9, injection pump 22, steam-pipe 3, power wind pipeline 1, fluid pipeline, ball valve 8, gate valve 2, vacuum breaker 4, safety valve 23.Medicament barrel 5 is connected with pneumatic diaphragm pump 6 import by pipeline, and drive pneumatic diaphragm pump work by the power wind of power wind pipeline 1 import, afterbody is provided with air silencer 7, exports and is communicated by the inlet pipeline of ball valve 8 with medicament storage tank 9.Electric mixer 10 is equipped with at medicament storage tank 9 top, and be provided with dosing mouth 14 and high some drain 15, liquid level gauge 11 and on the spot pressure indicator 12 on the spot sidewall be equipped with, bottom is provided with medicine outlet 16, sewage draining exit 17 and leakage fluid dram 18, high some drain pipeline and bottom leakage fluid dram pipeline converge to medicament recovery channel 20, connect medicament recovery place, the inlet pipeline of medicament storage tank 9 communicates with chemical agent blender pipeline 19, medicine outlet 16 is provided with flow gauge (FG) 13, is connected with injection pump 22 by ball valve, line strainer 21.The outlet of injection pump 22 is connected with under meter 24 on the spot, is connected chemical agent removes decanting point 25 with steam-pipe by vacuum breaker 4, gate valve 2; The emergency loop that the exit of injection pump is provided with emergency blow-down gate valve 2 and is made up of gate valve 2, safety valve 23.The signal Access Control room indication panel monitoring equipment running status of the liquid level gauge on the spot 11 in automatic medicament feeding system, on the spot pressure indicator 12, flow gauge (FG) 13, on the spot under meter 24, the electrical signal Access Control room control panel of pneumatic diaphragm pump 6, electric mixer 10, injection pump 22, realizes automatic operation by watch-keeping cubicle.
When equipment runs, chemical agent blender enters medicament storage tank 9 through dosing mouth 14 by pipeline and medicament simultaneously, stirred by electric mixer 10, volatilization gas discharges through height point drain 15, by the status information of solution in the liquid level gauge on the spot 11 of medicament storage tank 9 side, on the spot pressure indicator 12, flow gauge (FG) 13 Real-Time Monitoring chemical storage tanks; When needs cleaning and emptying medicament storage tank in chemical agent time, through bottom leakage fluid dram 18, solution, through recovery place of medicament recovery channel 20 to medicament, recycles; When the liquid in medicament storage tank need be discarded, the sewage draining exit 17 through bottom is discharged.
The chemical agent prepared in medicament storage tank, by medicine outlet 16 and pipeline, communicates with injection pump 22 fluid inlet through ball valve 8, line strainer 21; Gate valve 2 is equipped with at injection pump fluid inlet place, for emergent discharge during emergency situation; Flow gauge (FG) 13 is equipped with in the exit of injection pump, and liquid pressure in monitoring pipeline, the emergency loop being provided with emergency blow-down gate valve 2 and being made up of gate valve 2, safety valve 23, for the process of medicament during Special Circumstances.The outlet of injection pump 22 communicates with under meter 24 on the spot through pipeline, and under meter 24 is equipped with emergent gate valve 2 on the spot, guarantees that system runs well.Through the liquid that under meter 24 on the spot exports, by pipeline, chemical agent is finally gone to remove decanting point 25 by after line treatment that gate valve 2, vacuum breaker 4 be housed together with the vapour line 3 of gate valve 2, vacuum breaker 4, emergent gate valve 2 is installed.
The utility model passes through under meter on the spot, guarantees accurately adding of chemical agent, between under meter, safety valve is being housed on the spot simultaneously, is preventing the too high damage causing equipment of line pressure; Power airduct diatom is provided with emptying gate valve, prevents that blast is too high causes danger; Vapour line is equipped with vacuum breaker and blow-off valve, guarantees operational safety.
Operation of the present utility model:
1) liquid needed for medicament barrel 5 and chemical agent blender adds in corresponding bucket by artificial being responsible for;
2) pneumatic diaphragm pump 6 import and outlet conduit valve is opened;
