The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, system of the present utility model comprises sanitaryware 1, closed sludge collecting box 2, blowdown unit 3, sanitaryware 1 are installed in the washroom, closed sludge collecting box 2 and blowdown unit 3 are installed in the equipment room, and described sanitaryware 1 are connected with the inlet of closed sludge collecting box 2 by the blowoff line I, and the outlet of sewer 5 of described closed sludge collecting box 2 is connected to blowdown unit 3 by the blow-off pipe II; Be provided with and the outdoor vent line III that communicates at described closed sludge collecting box 2, be provided with ECU 17 and ight soil pond interface 18 at blowdown unit 3, be provided with long distance control system interface 15 on ECU 17, long distance control system connects 15 and connects long distance control system 16.
The sewage of sanitaryware 1 discharging is under the effect of the impact of flushing water and self gravitation, flow into closed sludge collecting box 2 through the blowoff line I, electric control valve II 7 is in normally open (the vent line III is unimpeded) at this moment, electric control valve I 8 is in normally off (vent line IV partition), sewage flows into closed sludge collecting box 2, foul smell unnecessary in the closed sludge collecting box 2 drains into outdoor through the vent line III, be provided with the pipeline that is connected to water service pipe at closed sludge collecting box 2, clear water enters closed sludge collecting box 2 by outlet pass 6, is provided with electric control valve III 19 on water-filled pipe.
When sewage stores up to liquid-level switch 11 in the closed sludge collecting box 2, rotary lobe pump I 13 operations in the blowdown unit 3, meanwhile, electric control valve II 7 is closed (vent line III partition), electric control valve I 8 is opened (the vent line IV is unimpeded), rotary lobe pump I 13 is in blowdown, and the gas in the washroom is inhaled into closed sludge collecting box 2 through the vent line IV.After the whole emptyings of dirt in the closed sludge collecting box 2,13 delay working a period of times of rotary lobe pump I, the gas in the washroom drains into municipal blowdown pipe network through closed sludge collecting box 2 and rotary lobe pump I 13 at this moment.The stopping of rotary lobe pump I 13 controlled by the time.
Behind the elapsed time T1, electric control valve II 7 is opened, and electric control valve I 8 is closed, and rotary lobe pump I 13 quits work, and system finishes drainage works one time.When treating that liquid-level switch I 11 has signal once more, 14 operations (two platform convex wheel pump alternations) of rotary lobe pump II, system repeats the above-mentioned course of work once more.
Be provided with two liquid-level switches in the closed sludge collecting box 2.Liquid-level switch I 11 is used for controlling the startup of rotary lobe pump.Liquid-level switch 12 is used for doing controlling alarm and detection.When liquid-level switch II 12 had signal, then illustrated liquid-level switch I 11 faults if lobe pump does not move work this moment, and the system alarm indicator lamp is bright, shows liquid-level switch I 11 faults and by remote monitoring interface 15 fault-signal is transferred on the manual board; When if liquid-level switch II 12 has signal, if lobe pump is in running status, at this moment, this platform convex wheel pump out of service, start another platform convex wheel pump, after a period of time, if liquid-level switch II 12 no signals, then the system alarm indicator lamp is bright, shows the lobe pump fault that is stopped and by the remote monitoring interface fault-signal is transferred to manual board; If after a period of time, liquid-level switch II 12 still has signal, then the system alarm indicator lamp is bright, the display system fault, and this moment, system quit work, and system failure signal is transferred to manual board by the remote monitoring interface.During the system failure, this washroom forbidding.
If liquid-level switch I 11 has fault, then system's cancellation is adopted the startup of liquid-level switch 12 control lobe pumps to the signals collecting of liquid-level switch I 11.
If wherein a platform convex is taken turns failure of pump, then system only controls another platform convex wheel pump work, does not have two pump alternate run operating modes this moment.After treating that the lobe pump fault is got rid of, enter the alternate run operating mode again.
System is provided with cleans the sludge collecting box function, and system's control bath electromagnetic valve II 7 is opened, and airtight sludge collecting box 2 is washed, and after a period of time, bath electromagnetic valve I 8 is closed, and flushing water is discharged in lobe pump work.
As shown in Figure 2, be provided with portable cell structure 9 in sewage inlet 4 sides, airtight sludge collecting box 2 bottoms, follow sewage and the foreign material that come, as silk stocking, key, mobile phone, coin etc. behind grid filtration, foreign material are retained in the grid, and sewage can flow freely inside and outside grid.During blowdown, sewage can be discharged by blowoff line, and foreign material are isolated in the grid, have increased the application life of pump.On described portable cell structure 9, be provided with grid handle 10, be provided with magnetic stripe in the grid, be used to adsorb metal impurities.
As shown in Figure 4, the control method that this system is concrete is as follows:
Does step 1 judge that liquid-level switch II 12 has signal? if have, judge whether liquid-level switch I 11 has signal, forwards step 2 to, if do not have, forward step 6 to;
Does step 2 judge that then rotary lobe pump I 13 moves if liquid-level switch I 11 has signal? forward step 3 to, if liquid-level switch I 11 there is not signal, then liquid-level switch I 11 alarm indications forward step 5 to;
Step 3 is if rotary lobe pump I 13 is moved, and rotary lobe pump I fault alarm shows, if do not have operation, forwards step 4 to;
Do step 4 rotary lobe pump II 14 operation setting-up time T2 judge that liquid-level switch II 12 has signal? if have, rotary lobe pump II 14 continues operation, if do not have, forwards step 8 to;
Does step 5 rotary lobe pump II operation setting-up time T2 judge that liquid-level switch II 12 has signal? if have, system failure alarm indication if do not have, forwards step 8 to;
Is step 6 judged in the sludge collecting box whether signal of liquid-level switch I 11? if signal is arranged, two lobe pump number of run startups are differentiated, forward step 7 to, if do not have signal, forward step 8 to;
13 operations of step 7 rotary lobe pump I reach setting-up time T1, forward step 8 to; 14 operations of rotary lobe pump II reach setting-up time T2, forward step 8 to;
