Fig. 2 be Fig. 1 described in sewage suction device in line A-A schematic cross-sectional view.
Specific implementation mode
The technical solution of this patent is described in more detail With reference to embodiment.
Please refer to Fig.1-2, a kind of filter for agricultural irrigation having from dirt eliminating function, including end cap 2, filter body
1, the both ends of coarse strainer 5, fie screen 6, water inlet pipe 4 and blow-off pipe 12, the filter body 1 have been respectively fixedly connected with end cap 2,
Symmetrical fixed connect in lower part of filter body 1 has water inlet pipe 4, is fixed positioned at water inlet pipe 4 and 1 contact position of filter body
It is embedded with coarse strainer 5, the inside middle of the filter body 1 is fixedly embedded to have fie screen 6, the inner wall of the end cap 1 to fix
It is connected with bearing 7, the inner wall fixing sleeve of bearing 7 is connected to Rotational Cylindrical 8, and the surface of Rotational Cylindrical 8 is fixedly connected with propeller 9, rotation
The not-go-end of column 8 is fixedly connected with the dirt sucking tube 10 towards the one end open among filter body 1, the filter body 1
Bosom is provided with fixed ring 11, and the end of the dirt sucking tube 10 is connect with the inner wall phase dynamic sealing of fixed ring 11, described
The blow-off pipe 12 connected and have activity to run through filter body 1 is fixed in the lower part of fixed ring 11, is located at the row in 1 outside of filter body
Blowdown valve 13 is installed on dirty pipe 12, the surface of the dirt sucking tube 10 is fixedly connected with several groups sewage suction device along its length,
Every group of sewage suction device includes several conically shapeds 16 being arranged along 10 circumferential surface of dirt sucking tube and connecting rod 18, conically shaped 16 and dirt sucking tube
10 inner wall is mutually fixed to be connected, and the not-go-end surface of conically shaped 16 is in arcuate shape corresponding with 6 inner wall of fie screen and taper 16
The not-go-end surface of cylinder is uniformly provided with several suction inlets 17, and the end of the connecting rod 18 is fixedly connected with opposite with 6 inner wall of fie screen
The arc brush board 19 answered；Raw water is entered after coarse strainer 5 in filter body 1, and larger particle suspensions are by coarse strainer 5
It intercepts, prevents larger particle suspensions from entering in fie screen 6, the effect of protection is played to fie screen 6 and dirt sucking tube 10,
Water after coarse filtration enters inside fie screen 6, and thinner suspended matter is such as in water：Algae, iron rust, foundry loam, microorganism etc. are intercepted
On 6 inner surface of fie screen.With the continuous accumulation of suspended matter, a pressure difference is just produced between 6 surfaces externally and internally of fie screen.
When pressure difference constantly increases, and reaches preset value 0.03-0.05MPa value ranges, blowdown valve 13 is automatically switched on, dirt sucking tube 10 because
Blowdown valve 13 is opened and rapid pressure drop, to generate one suction at suction inlet 17, can will be gathered on 6 inner surface of fie screen
Suspended matter sucking dirt sucking tube 10 in, at the same time, when raw water enters filter body 1 by water inlet pipe 4, due to a constant current
The flow of speed passes through propeller 9, makes propeller 9 that Rotational Cylindrical 8 be driven to be rotated, to make dirt sucking tube 10 be rotated, therefore
So that arc brush board 19 is rotated the inner surface of fie screen 6, makes the suspended matter being adhered on the inner surface of fie screen 6 by again
It is mobile, and subsequent suction inlet 17 improves the suction to fie screen inner surface by the suspended matter inspiration dirt sucking tube 10 re-moved
Dirty ability, and since dirt sucking tube 10 persistently rotates, make that suspended matter dead angle is not present on the circumferential surface of fie screen 6, carry
High soil pick-up quality.
The end cap 2 is fixedly connected by self-tapping screw 3 with 1 phase of filter body, convenient for the peace loading and unloading to end cap 2
Under.
The propeller 9 is located at the axial line distance range of the side towards the middle of water inlet pipe 4 and propeller 9 and water inlet pipe 4
For 5-30mm, flow is made to pass through propeller 9 to make propeller 9 be rotated.
The fixed ring 11 is mutually fixedly connected by connecting rod 18 with the inner wall of filter body 1, is played to fixed ring 11
Support fixed effect.
Fixed bonding has sealing rubber ring 15, the dirt sucking tube 10 to pass through sealing rubber ring respectively at the both ends of the fixed ring 11
15, improve the sealing performance between fixed ring 11 and dirt sucking tube 10.
The conically shaped 16 and connecting rod 18 are staggeredly set along the circumferential surface of dirt sucking tube 10.
The clearance distance of the not-go-end surface of the conically shaped 16 and the inner wall of fie screen 6 is 1-8mm.
The surface of the brush board 19 is fixedly connected with several bristles 20, improves the ability to bring along to suspended matter.
The operation principle of the utility model is：Raw water is entered after coarse strainer 5 in filter body 1, larger
Grain suspended matter is intercepted by coarse strainer 5, prevents larger particle suspensions from entering in fie screen 6, to fie screen 6 and dirt sucking tube
10 play the effect of protection, and the water after coarse filtration enters inside fie screen 6, and thinner suspended matter is such as in water：Algae, is glued iron rust
Mud, microorganism etc. are intercepted on 6 inner surface of fie screen.With the continuous accumulation of suspended matter, between 6 surfaces externally and internally of fie screen just
Produce a pressure difference.When pressure difference constantly increases, and reaches preset value 0.03-0.05MPa value ranges, blowdown valve 13 is automatic
Open, dirt sucking tube 10 because blowdown valve 13 is opened and rapid pressure drop can will be thin to generating one suction at suction inlet 17
In the suspended matter sucking dirt sucking tube 10 gathered on 6 inner surface of strainer, at the same time, raw water enters filter by water inlet pipe 4
When ontology 1, since the flow of certain flow rate passes through propeller 9, make propeller 9 that Rotational Cylindrical 8 be driven to be rotated, to make soil pick-up
Pipe 10 is rotated, therefore arc brush board 19 is made to rotate the inner surface of fie screen 6, makes the interior table for being adhered to fie screen 6
Suspended matter on face is re-moved, and subsequent suction inlet 17 is improved in the suspended matter inspiration dirt sucking tube 10 re-moved
To the soil pick-up ability of fie screen inner surface, and since dirt sucking tube 10 persistently rotates, make on the circumferential surface of fie screen 6 not
There are suspended matter dead angles, improve soil pick-up quality.
