Fig. 1 is a kind of embodiment of the defecator of sewage pump suction inlet of the present invention, the defecator of described sewage pump suction inlet includes at least Liang Tao contaminant filter mechanism, and described contaminant filter mechanism includes sewage suction tube 1, impurity cleans pipe 2, impurity exhaust conduit 3, drainage screen A9 and controller。One end of described sewage suction tube 1 is free end, and the other end can be connected with Pump Suction Nozzle 4；It is provided with drainage screen A9 in described sewage suction tube 1；Valve A5 and valve B6 it is respectively equipped with before and after described drainage screen A9。Impurity cleans one end of pipe 2 and can be connected with pumping the mouth of a river 11, and the other end is connected and between drainage screen A9 and valve B6 with described sewage suction tube 1；Described impurity cleans pipe 2 and is provided with valve C7。One end of impurity exhaust conduit 3 is free end, and the other end is connected and between drainage screen A9 and valve A5 with described sewage suction tube 1；Described impurity exhaust conduit 3 is provided with valve D8。Impurity exhaust conduit 3 is arranged on the front of drainage screen, and impurity can be made to discharge smoothly。
As shown in Figures 2 and 3, it is additionally provided with drainage screen B10 in described sewage suction tube 1；Described drainage screen B10 is slidably connected between impurity exhaust conduit 3 and drainage screen A9 and with described sewage suction tube 1。Preferably, being respectively provided on two sides with of described drainage screen B10 props up a bracer 12；Prop up bracer 12 and be provided with cylindrical roller 13；Described sewage suction tube 1 inwall is provided with groove 14 accordingly, as shown in Figure 4。Described bracer 12 is stretched in groove 14 and is slided in groove 14 by described ball 13, it is to avoid impurity passes through。Described filter screen B10 can move back and forth along sewage suction tube 1 under the effect of current。The internal diameter of described drainage screen A9 and described drainage screen B10 is equal, and the reticulate pattern on described drainage screen A9 and drainage screen B10 is orthogonal。When sewage suction water pipe 1 absorbs water, drainage screen B10 moves forward and overlaps with described filter screen A9, so not only can reach the effect of double filtration, and when impurity cleaning pipe 2 works, current make drainage screen B10 be moved rearwards by with drainage screen A9 respectively, to remove the impurity being wrapped on drainage screen。
Described sewage suction tube 1 is divided into water absorbing section 101 and drainage screen construction section 102；The internal diameter of described water absorbing section 101 is less than the internal diameter of drainage screen construction section 102。The range of movement of described drainage screen B10 can be limited so that it is be maintained at the rear of impurity exhaust conduit 3。
Described water absorbing section 101 is connected by flange 16 with drainage screen construction section 102, it is possible to regular dismounting, convenient cleaning。
Described controller is connected with the valve A5 in Liang Tao contaminant filter mechanism, valve B6, valve C7 and valve D8 respectively；Described controller by controlling valve A5, the switch of valve B6, valve C7 and valve D8 control the alternation of Liang Tao contaminant filter mechanism。
Fig. 5 show the control circuit of described controller, and described control circuit includes branch road one and branch road two；Valve A5 in switch 1 that described branch road one includes being sequentially connected in series, first set contaminant filter mechanism and the valve C7 in valve B6 and the second set contaminant filter mechanism and valve D8；Valve C7 on valve A5 in described branch road two includes being sequentially connected in series switch the 2 18, second set contaminant filter mechanism and valve B6 and first set contaminant filter mechanism and valve D8；Described branch road one and branch road two are in parallel, and described branch road one and branch road two after parallel connection are connected with switch 3 19, power supply 20 and resistance 21 successively。
Described switch 1 and switch 2 18 are interlock switch, when described switch 1 disconnects, and switch 2 18 Guan Bi, when described switch 1 closes, switch 2 18 disconnection。
Present invention additionally comprises two intervalometers 15, described intervalometer 15 electrically connects with described controller respectively, in parallel with described switch 1 and switch 2 18 respectively at intervalometer 15 described in control circuit, described intervalometer 15 can arrange the time of runs according to the concentration of impurities in water, described controller is according to the switch of time control valve arranged, thus realizing the automatization of Liang Tao contaminant filter mechanism alternation。
The operation principle of the present invention: when the sewage suction tube 1 of wherein a set of contaminant filter mechanism carries out contaminant filter work, now controller controls the valve A5 above it and valve B6 and opens, valve C7 and valve D8 closes, by the effect of current, drainage screen B10 is moved forward overlap with drainage screen A9, reach the purpose filtered。And the sewage suction tube 1 of another set of contaminant filter mechanism carries out impurity cleaning, now controller controls the valve A5 above it and valve B6 cut out, valve C7 and valve D8 opens, the water pumping the mouth of a river 11 cleans pipe 2 cleaned filter screen B10 and drainage screen A9 by impurity, at this moment drainage screen B10 is moved rearwards by with drainage screen A9 separately under the flushing of current, being discharged by impurity exhaust conduit 23 of the impurity of flushing。
According to the size of impurity concentration in medium, arranging the working time of intervalometer 15, the time one arrives so that the valve A5 and valve B6 that originally carry out the contaminant filter mechanism of contaminant filter work close, and valve C7 and valve D8 opens, and stops water suction and enters impurity cleaning process。And the valve A5 and valve B6 that originally carry out the contaminant filter mechanism of impurity cleaning open, valve C7 and valve D8 closes, and stops impurity and cleans entrance water absorption course。
Sewage, by the alternation of contaminant filter and cleaning, is filtered by the present invention continuously, utilizes impurity to clean the water in pipe 2 and carrys out washing filter screen, and is discharged by impurity exhaust conduit 2。Avoid sewage pump or pipeline generation plugging fault, the pump housing need not be dismantled frequently, reduce the harm to the pump housing, while improving the pump housing life-span, it is ensured that the life cycle that sewage pump is enough, improve the work efficiency of pump simultaneously。
Described embodiment be the present invention preferred embodiment; but the present invention is not limited to above-mentioned embodiment; when without departing substantially from the flesh and blood of the present invention, those skilled in the art can make any conspicuously improved, replace or modification belongs to protection scope of the present invention。
