Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig.1~3, in the embodiment of the present invention, a kind of efficient municipal wastewater filter device, including filter 7, institute
It is closed L-shaped structure to state filter 7, is equipped with turntable 10 at the corner position of filter 7, turntable 10 is driven by decelerating motor
It rotates, is hingedly installed with one end of connecting rod 1 and connecting rod 2 14 simultaneously at the eccentric position of turntable 10, connecting rod 1 and connecting rod
2 14 the piston 1 at 7 both sides position of filter and piston 2 19 connect everywhere respectively, piston 1 and piston 2 19 with
The side wall of filter 7 cooperatively forms the filter chamber 1 and filter chamber 2 20 of variable volume, when decelerating motor exports power, turns
Disk 10 rotates synchronously, and by the gearing of connecting rod 1 and connecting rod 2 14, piston 1 and piston 2 19 are past in filter 7
Multiple movement so that alternately reciprocal variation, filter chamber 1 and filter chamber occurs in the volume of filter chamber 1 and filter chamber 2 20
2 20 are connected separately with outlet pipe 1 and outlet pipe 2 21, and strainer one is separately installed in outlet pipe 1 and outlet pipe 2 21
18 and strainer 2 22, the branch pipe 1 being connected to filter chamber 1 and filter chamber 2 20 is respectively equipped at the end positions of filter 7
With branch pipe 2 12, check valve 1 and check valve 2 11, branch pipe 1 and branch pipe two are separately installed on branch pipe 1 and branch pipe 2 12
12 connect with the feed liquor house steward 6 for inputting sewage, and the decelerating motor is electrically connected with power supply and control switch.
The feed liquor house steward 6 is extend into clear water reserviors 4, and a side position of clear water reserviors 4 is equipped with sedimentation basin 2, sedimentation basin 2 and clear
It is separated with partition board 3 between pond 4, the height of partition board 3 is slightly lower so that in the supernatant liquor energy overflow to clear water reserviors 4 of sedimentation basin 2,
The top of sedimentation basin 2 is equipped with for the dosing tank 5 to its dosing, for flocculant to be added into sedimentation basin 2, convenient for the heavy of impurity
Drop, clear water reserviors 4 are connect with sewage pipe 1.
The strainer 1 and strainer 2 22 are mounted on one 17 He of outlet pipe by way of flange 23 and bolt presses
On outlet pipe 2 21, dismounting is more convenient.
The outlet pipe 1 and outlet pipe 2 21 are connect with total outlet pipe, and are equally equipped in total outlet pipe unidirectional
Valve can prevent the water in total outlet pipe from flowing back.
The resigning to turntable 10 is equipped at the corner position of the filter 7, which can be arc or chamfering structure.
It is equipped with the liquid level detection device being detected to its liquid level in the clear water reserviors 4, understands clear water in time convenient for personnel
The inside liquid level in pond 4 avoids filter 7 from idle running phenomenon occur.
The bottom of the sedimentation basin 2 is connected with blow-off pipe, and dredge pump is equipped on blow-off pipe, for that will be deposited on sedimentation basin
The sludge impurity of 2 bottoms is discharged.
Multiple inclined baffles are installed in the clear water reserviors 4, reduce or prevent to be deposited on the impurity of 4 bottom of clear water reserviors
It is floating, reduce the live load of strainer 1 and strainer 2 22.
The strainer 1 and strainer 2 22 are all made of metal material and are made.
The present invention operation principle be：When work, sewage is entered by sewage pipe 1 in sedimentation basin 2, passes through dosing at this time
Appropriate flocculant is added into sedimentation basin 2 for case 5, and the impurity in sewage can be settled, while continuing to input with sewage,
Supernatant liquor in sedimentation basin 2 overflows in clear water reserviors 4, starts decelerating motor at this time, and turntable 10 rotates synchronously, and passes through connecting rod one
13 and connecting rod 2 14 gearing, piston 1 and piston 2 19 move back and forth in filter 7 so that one 16 He of filter chamber
There is alternately reciprocal variation in the volume of filter chamber 2 20, and by taking filter chamber 2 20 as an example, there are imbibition and discharge opeing process, imbibitions
When, the water in clear water reserviors 4 is entered by branch pipe 2 12 and check valve 2 11 in filter chamber 2 20, enters discharge opeing process later,
Due to the design of check valve 2 11, sewage can only be flowed out from outlet pipe 2 21, after the forced filtration of filter screen 2 22, impurity quilt
Retention, clean water are discharged from outlet pipe 2 21, carry out imbibition and discharge opeing process again later.
It should be strongly noted that in the technical program, filter 7, turntable 10, connecting rod 1, connecting rod 2 14, piston one
15 and piston 2 19 etc. are the application of the prior art, and carry out the innovation that forced filtration is the application to sewage using piston
Point, can efficiently to the water of clear water reserviors carry out forced filtration, it is simple in structure without being stood for a long time, operate nor
It is often convenient.
