When handling sewage with the present apparatus, sewage is poured on I 2-10 of filter screen, one end time is then allowed to stand, sewage is made to pass through filter screen I
2-10, impurity are trapped in I upper end 2-10 of filter screen, then start motor 1-4, and motor 1-4 band moving gear 1-3 is rotated, gear 1-3
Turntable 1-1 rotation is driven, turntable 1-1 band moving sleeve 1-6 is rotated, and sleeve 1-6 drives push plate 1-8 mobile, and push plate 1-8 is located at filtering
The upper end of I 2-10 of net pushes the impurity on I 2-10 of filter screen in push plate 1-8 when I upper end 2-10 of filter screen is mobile, when pushing away
When plate 1-8 is moved on inclined plate 2-12-4, the upward compressed spring 1-7 of push plate 1-8, since the level height of II 2-12-5 of through-hole is big
In the height of I 2-10 of filter screen, water level will not cover inclined plate 2-12-4, when push plate 1-8 is moved to II upper end 2-12-5 of through-hole,
Impurity is fallen under the effect of gravity on bottom plate 2-12-1, is then discharged by sewage draining exit 2-13, and the table of I 2-10 of filter screen is completed
Face cleaning;Sewage is detached from the laggard aggregation of conical plate 2-6 excessively of I 2-10 of filter screen and drops down onto III 4-2-1 of cylinder, then drops down at random
In IV 4-2-3 of strainer, V 4-2-4 of filter screen, can block to avoid III 4-2-2 of filter screen causes to influence filter efficiency in this way, when
After a certain III 4-2-2 of location filtering net blocking, sewage flow to other positions by IV 4-2-3 of filter screen, V 4-2-4 of filter screen
It at III 4-2-2 of filter screen and excludes, little particle impurity is trapped in III upper end 4-2-2 of filter screen, completes primary filtering;It is detached from filtering
Sewage after III 4-2-2 of net drops down onto a main body 3-1-1-1, and the sewage in cylinder main body 3-1-1-1 provides buoyancy for floating block 3-3-3
And cylinder 3-3-2 is pushed up, the coagulant on supporting plate 3-2-2 is exposed and is merged with sewage, by the impurity in sewage
Cohesion, the device are advantageous in that the coagulant that can be mixed into different number according to the volume of sewage, avoid wasting, finally stand
For a period of time, pull pull plate 3-1-2, it is processed after water discharge.
Specific embodiment 2:
Illustrate present embodiment below with reference to Fig. 1,2,3,4,5,6,7,8,9,10,11,12, present embodiment is to embodiment party
Formula one is described further, and the level height of II 2-12-5 of through-hole is greater than the height of I 2-10 of filter screen.
Specific embodiment 3:
Illustrate present embodiment below with reference to Fig. 1,2,3,4,5,6,7,8,9,10,11,12, present embodiment is to embodiment party
Formula one is described further, the ring baffle 3-3-1, cylinder 3-3-2 material be plastics.
Specific embodiment 4:
Illustrate present embodiment below with reference to Fig. 1,2,3,4,5,6,7,8,9,10,11,12, present embodiment is to embodiment party
Formula one is described further, and the height of IV 4-2-3 of filter screen is less than the height of V 4-2-4 of filter screen.
The working principle of the invention is: when using present apparatus processing sewage, sewage being poured on I 2-10 of filter screen, then
One end time is stood, makes sewage by I 2-10 of filter screen, impurity is trapped in I upper end 2-10 of filter screen, then start motor 1-4,
Motor 1-4 band moving gear 1-3 is rotated, and gear 1-3 drives turntable 1-1 rotation, and turntable 1-1 band moving sleeve 1-6 is rotated, sleeve 1-6
Drive push plate 1-8 mobile, push plate 1-8 is located at the upper end of I 2-10 of filter screen, mobile in I upper end 2-10 of filter screen in push plate 1-8
When, the impurity on I 2-10 of filter screen is pushed, when push plate 1-8 is moved on inclined plate 2-12-4, push plate 1-8 compresses bullet upwards
Spring 1-7, since the level height of II 2-12-5 of through-hole is greater than the height of I 2-10 of filter screen, water level will not cover inclined plate 2-12-4,
When push plate 1-8 is moved to II upper end 2-12-5 of through-hole, impurity is fallen under the effect of gravity on bottom plate 2-12-1, is then passed through
Sewage draining exit 2-13 discharge, completes the surface cleaning of I 2-10 of filter screen;Sewage is detached from the laggard conical plate 2-6 that crosses of I 2-10 of filter screen and gathers
Collection drops down onto III 4-2-1 of cylinder, then drops down at random in IV 4-2-3 of filter screen, V 4-2-4 of filter screen, in this way can be to avoid mistake
III 4-2-2 of strainer blocking causes to influence filter efficiency, and after a certain III 4-2-2 of location filtering net blocking, sewage passes through filter screen
IV 4-2-3, V 4-2-4 of filter screen flow at III 4-2-2 of filter screen of other positions and exclude, and little particle impurity is trapped in filtering
Primary filtering is completed in III upper end 4-2-2 of net;Sewage after being detached from III 4-2-2 of filter screen drops down onto a main body 3-1-1-1, cylinder master
Sewage in body 3-1-1-1 provides buoyancy for floating block 3-3-3 and pushes up cylinder 3-3-2, makes the coagulation on supporting plate 3-2-2
Agent is exposed and is merged with sewage, and the impurity in sewage is agglomerated, which is advantageous in that can be mixed according to the volume of sewage
The coagulant for entering different number avoids wasting, finally stand a period of time, pull pull plate 3-1-2, it is processed after water discharge
