Dirt collecting tank 2 is collected the sewage of suction-type sewer scavenger suction.Further describe the internal structure of dirt collecting tank 2 below with reference to Fig. 2.
Figure 2 shows that the structural representation of dirt collecting tank 2 according to an embodiment of the invention.In one embodiment, dirt collecting tank 2 comprises dirt collecting tank liquid level sensor 1.Dirt collecting tank liquid level sensor 1, for measuring the water level of dirt collecting tank 2, produces the first transducing signal that represents dirt collecting tank 2 water levels, and sends the first transducing signal to PLC controller 102.Dirt collecting tank 2 also comprises floating suction inlet 3, soil pick-up control valve 15, anti-control valve 16 and the effluent cycle control valve 17 arranged.
The structure of floating suction inlet 3 is described below in conjunction with Fig. 2 and Fig. 3.
Figure 3 shows that the structural representation of floating suction inlet 3 according to an embodiment of the invention.Floating suction inlet 3 comprises sewer water inlet 30, dirt collecting tank delivery port 31, dirt collecting tank water inlet 32, flexible pipe 20, water wing 23, float guide rod 19, float supporting seat 18 and water wing rotating seat 24.Soil pick-up control valve 15 is installed between dirt collecting tank delivery port 31 and sewer water inlet 30.Anti-row's control valve 16 is installed between dirt collecting tank water inlet 32 and sewer water inlet 30.Effluent cycle control valve 17 is installed on the junction of flexible pipe 20 and dirt collecting tank water inlet 32.At work, by regulating soil pick-up control valve 15 and anti-row's control valve 16 can control the mode of operation of floating suction inlet 3, by regulating effluent cycle control valve 17 can open or close the dirty water decontamination handles function, these contents will be described in detail after a while.
Get back to Fig. 1, self priming pump 13 is connected with dirt collecting tank 2.More particularly, self priming pump 13 is connected with the flexible pipe 20 of floating suction inlet 3 by effluent cycle control valve 17.Hydraulic-driving self-washing filter 5 is connected with self priming pump 13, for sewage is carried out to primary filter.Cyclone 6 is connected with hydraulic-driving self-washing filter 5, for sewage is carried out to second level filtration.Multi stage precipitation water tank 7 is connected with cyclone 6, for sewage is carried out to multi stage precipitation separation.Sewage pump 10 is connected with multi stage precipitation water tank 7.Electric drive backwashing filter 11 is connected with sewage pump, filters for sewage being carried out to essence.Filtered water tank 29 is connected with electric drive backwashing filter 11, for collecting multistage purification clear water after treatment.In one embodiment, filtered water tank 29 comprises filtered water tank liquid level sensor 8, for measuring the water level in filtered water tank 29, produces the second transducing signal that represents filtered water tank water level, and sends the second transducing signal to PLC controller 102.
PLC controller 102 produces the soil pick-up control valve 15 in multiple control signal control dirt collecting tanks 2, anti-control valve 16 and the effluent cycle control valve 17 arranged, and also can produce control signal control generator 12, sewage pump 10 and self priming pump 13.In the time that suction-type sewer scavenger starts soil pick-up work, PLC controller 102 opens soil pick-up control valve 15 and cuts out anti-row's control valve 16, thereby makes floating suction inlet 3 work in effluent cycle reuse mode.Now, the vavuum pump in dirt collecting tank 2 absorbs dirt collecting tank 2 inner airs, reduces the air pressure inside of dirt collecting tank 2.Sewage outside suction-type sewer scavenger sucks dirt collecting tank 2 by sewer water inlet 30 and the dirt collecting tank delivery port 31 of floating suction inlet 3.That is to say, the water level of dirt collecting tank 2 increases gradually.
PLC controller 102 obtains the water level situation of dirt collecting tank 2 and filtered water tank 29 by the first transducing signal and the second transducing signal.Wherein, when the first transducing signal and the second transducing signal represent that the water level of dirt collecting tank 2 is greater than the first preset water level threshold value (representing that dirt collecting tank 2 is about to fill sewage), and, in the time that the water level of filtered water tank is less than the second preset water level threshold value (water that represents filtered water tank is about to be finished), PLC controller 102 is opened self priming pump 13 and sewage pump 10.Meanwhile, PLC controller 102 is opened effluent cycle control valve 17, thereby makes self priming pump 13, by dirt collecting tank water inlet 32 and flexible pipe 22, the water of dirt collecting tank 2 is pumped into hydraulic-driving self-washing filter 5.More particularly, dirt collecting tank 2 superficial waters are through the water inlet 21 of floating suction inlet 3, flexible pipe 22 enters into self priming pump 13, carry out circular regeneration processing, water wing 23 is along with the variation of water level, under the support of float guide rod 19, rotate around float supporting seat 18, under 24 effects of water wing rotating seat, water wing 23 is all the time in level.Then, hydraulic-driving self-washing filter 5 carries out primary filter to the sewage from dirt collecting tank 2, and the sewage after primary filter is entered to cyclone 6.Cyclone 6 carries out second level filtration to the sewage from hydraulic-driving self-washing filter 5, and the water after the filtration of the second level is entered to multi stage precipitation water tank 7.Multi stage precipitation water tank 7 carries out multi stage precipitation separation to the sewage from hydraulic-driving self-washing filter 5, and by sewage pump 10, the water after multi stage precipitation separation is pumped into electric drive backwashing filter 11.Electric drive backwashing filter 11 sends to such an extent that water carries out essence filtration to sewage pump 10, and deposits later after filtration water in described filtered water tank 29.
Advantage is, multi-stage sewage cycle for the treatment of recycling system of the present invention can be at the water level of the dredging of suction-type sewer scavenger high pressure or vacuum soil pick-up stage monitoring dirt collecting tank and filtered water tank, and carries out sewage disposal according to monitoring water level.That is to say, when the water that soon stores full and filtered water tank when the sewage of dirt collecting tank will be finished, multi-stage sewage cycle for the treatment of recycling system of the present invention can be that clear water stores filtered water tank into by the dirty water decontamination handles of dirt collecting tank in time.Therefore, increase the suction-type sewer scavenger activity duration, improved soil pick-up efficiency.
In addition, multi-stage sewage cycle for the treatment of recycling system 100 also adopts multistage filtering and multi stage precipitation device.More particularly, hydraulic-driving self-washing filter 5 grade of filtrations are greater than the particulate of first threshold, cyclone 6 grade of filtrations are greater than the particulate of Second Threshold, electric drive backwashing filter 11 grade of filtrations are greater than the particulate of the 3rd threshold value, wherein, first threshold is greater than Second Threshold, and Second Threshold is greater than the 3rd threshold value.For example, when hydraulic-driving self-washing filter 5 carries out primary filter, can be by the above particulate of 300 μ in pneumatic control valve 4 to be sent into dirt collecting tank 2, the sewage of granularity below 300 μ enters into cyclone 6 and processes.Cyclone 6 can be sent into particulates more than 150 μ in dirt collecting tank 2, and the particulate below 150 μ can enter multi stage precipitation water tank 7 and carry out precipitate and separate step by step.After the smart filter operation of electric drive backwashing filter 11, the qualified water below 20 μ is sent back to filtered water tank 29.As can be seen here, multi-stage sewage cycle for the treatment of recycling system 100 has improved sewage disposal granularity, has reduced use and the maintenance cost of suction-type sewer scavenger.
The water level that represents dirt collecting tank 2 when the first transducing signal and the second transducing signal is lower than the first preset water level threshold value (representing that dirt collecting tank 2 wastewater level are relatively low), or, when the water level of filtered water tank is during higher than the second preset water level threshold value (water that represents filtered water tank is about to fill), PLC controller 102 cuts out self priming pump 13 and sewage pump 10.Meanwhile, PLC controller 102 cuts out effluent cycle control valve 17.Now, suction-type sewer scavenger stops sewage conversion work.
Get back to Fig. 3, floating suction inlet 3 can also work in the anti-pattern of arranging of high pressure.At high pressure, instead under row's pattern, PLC controller 102 cuts out soil pick-up control valve 15 and effluent cycle control valve 17, and opens anti-row's control valve 16.Vavuum pump in dirt collecting tank 2, to dirt collecting tank 2 inner air pressurizations, makes the water of dirt collecting tank 2 discharge dirt collecting tank 2 by dirt collecting tank water inlet and sewer water inlet.
Figure 4 shows that the structural representation of filtered water tank and multi stage precipitation water tank 7 according to an embodiment of the invention.In one embodiment, multi stage precipitation water tank 7 is furnished with self-cleaning system, can timing carry out cleaning to inner sediment, in the time carrying out cleaning, effluent cycle recycling system is in the state of quitting work, and multistagely sinks to the bottom water tank control valve 28 and high-pressure hydraulic pump control valve 26 is opened, and high-pressure hydraulic pump 25 is in running order, now water under high pressure rinses precipitation water tank through high pressure washing shower nozzle 27, and the water after flushing sinks to the bottom water tank control valve 28 and associated conduit is discharged to sewer through multistage.
Figure 5 shows that the workflow diagram 500 of multi-stage sewage cycle for the treatment of recycling system 100 according to an embodiment of the invention.In one embodiment, multi-stage sewage cycle for the treatment of recycling system 100 can be operated in automatic catch or control manually.In step 502, multi-stage sewage cycle for the treatment of recycling system 100 starts.In step 504, if multi-stage sewage cycle for the treatment of recycling system 100 is in automatic catch, enter step 508.Otherwise flow chart enters step 506, this system is by manually controlling.
In step 508, whether detect filtered water tank 29 in exsiccosis.If the water level of filtered water tank 29, lower than Second Threshold (, represent lack of water), enters step 510.Otherwise flow chart rests on step 508 to be continued to detect.In step 510, whether the water level that detects dirt collecting tank 2 reaches processing water level.If the water level of dirt collecting tank 2, higher than first threshold (, represent reach process water level), enters step 512-518.Otherwise flow chart 500 is got back to step 508.
In step 512-518, close respectively anti-row's control valve 16, open effluent cycle control valve 17, open self priming pump 13 and open slag notch control valve.Now, the sewage in dirt collecting tank 2 is done multistage purification processing by multi-stage sewage cycle for the treatment of recycling system 100, and water after treatment is put into multi stage precipitation water tank 7 precipitate purified treatment.
In step 520, for example, if afterbody (: No. 4) precipitation water tank reaches designated water level, enter step 522 and 524, open centrifugal soil pick-up pump 10 and generator 12.Now, the water of multi stage precipitation water tank 7 is admitted to electric drive and sends out the 11 work essence filtrations of flushing cleaner.
In step 526, if dirt collecting tank 2 reaches operation lowest water level or filtered water tank 29 is filled water (water level that is dirt collecting tank 2 is less than first threshold, or the water level of filtered water tank 29 is higher than Second Threshold), enter step 528, multi-stage sewage cycle for the treatment of recycling system 100 quits work.
