Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
Embodiment 1
A kind of automatic cleaning strainer, including housing 1 and the control device 12 on the housing 1, in the housing 1
Internal layer screen pack 2 and outer filter net 3 are coaxially arranged with, one end of the internal layer screen pack 2 is provided with rotating base 4, described
The top of housing 1 is provided with the motor 5 for driving the rotating base 4 to rotate；Gathered on the outer wall of the internal layer screen pack 2
There is just brush 6, the inner side of the internal layer screen pack 2 is provided with internal layer cleaning device；
Water inlet 7, delivery port 8, the first sewage draining exit 9, the and of the second sewage draining exit 10 are respectively arranged with the side wall of the housing 1
Pressure difference switch 11, the water inlet 7 and second sewage draining exit 10 are respectively communicated with the internal layer screen pack 2, the He of delivery port 8
First sewage draining exit 9 is respectively communicated with the outer filter net 3；
The pressure difference switch 11 is arranged between the water inlet 7 and the delivery port 8, the pressure difference switch 11, described
Motor 5 and the internal layer cleaning device electrically connect with the control device 12 respectively.
Preferably, it is equal at the water inlet 7, the delivery port 8, first sewage draining exit 9 and second sewage draining exit 10
The magnetic valve electrically connected with the control device 12 is provided with, the control device 12 controls unlatching and the pass of the magnetic valve
Close, so as to open or close the water inlet 7, the delivery port 8, first sewage draining exit 9 or second sewage draining exit 10.
In order to ensure the sealing of the automatic cleaning strainer, prevent seawater from leaking, the rotating base 4 and the shell
Sealing structure is provided between body 1, in the present embodiment, the sealing mechanism is multi-layer sealed circle 18.
Preferably, the pore size filter of the internal layer screen pack 2 is more than the pore size filter of the outer filter net 3, is filtering
During, the internal layer screen pack 2 is used for the rubbish and large granular impurity for filtering large volume, and the outer filter net 3 was used for
Filter little particle impurity.
During the automatic cleaning strainer work, seawater to be filtered is entered by the water inlet 7, by the internal layer mistake
After the double filtration of filter screen 2 and the outer filter net 3, follow-up technique is carried out from the delivery port 8 outflow；Rubbish in seawater
Rubbish and granule foreign are trapped within the internal layer screen pack 2 and the outer filter net 3.The time used is longer, is trapped
The rubbish and granule foreign to get off is just more and more, causes the filter opening of the internal layer screen pack 2 and the outer filter net 3 more next
Smaller, the rate of filtration is slower and slower, thus produces pressure differential between the water inlet 7 and the delivery port 8；It is new in this practicality
In type, the pressure difference switch 11 is used to detect the pressure differential between the water inlet 7 and the delivery port 8, when pressure differential reaches
During setting value, the pressure difference switch 11 sends electric signal to the outer layer cleaning device and the internal layer cleaning device, while small
Granule foreign is discharged by first sewage draining exit 9, and the rubbish and large granular impurity of large volume are discharged by second sewage draining exit 10；
After the outer filter net 3 and the internal layer screen pack 2 clean, between the water inlet 7 and the delivery port 8
Pressure differential is minimized being worth, and now system returns to inceptive filtering shape, normal operation.
Specifically, the internal layer cleaning device includes rotary screw 13, the screw mandrel bottom being set on the rotary screw 13
Seat 14 and be arranged on the housing 1 the other end rotary screw motor 15, one end of the rotary screw 13 is fixed
On the internal layer screen pack 2, the other end of the rotary screw 13 drives after passing through the rotating base 4 with the rotary screw
Dynamic motor 15 connects；The rotary screw motor 15 is also connected with the control device 12, is set in the screw mandrel base 14
There is scraper plate 16.
When pressure differential reaches setting value, the pressure difference switch 11 sends electric signal to the control device 12, the control
Device 12 processed controls the rotary screw motor 15 to start, and drives the rotary screw 13 to rotate, the screw mandrel base 14
Start to rotate and move along the rotary screw 13, so that the scraper plate 16 in the screw mandrel base 14 is relative to the internal layer mistake
Filter screen 2 moves, the large granular impurity and large volume rubbish adhered on the comprehensive cleaning internal layer screen pack 2.
Specifically, the both ends of the rotary screw 13 are respectively arranged with limit switch, the limit switch and the rotation
Screw drive motor 15 connects, it is preferred that the limit switch is travel switch or microswitch.When the screw mandrel base 14 is touched
When encountering the limit switch, the limit switch sends electric signal to the rotary screw motor 15, the rotating wire
Bar motor 15 drives the forward or reverse of rotary screw 13, realizes the silk according to the electric signal forward or reverse
The reciprocating motion of bar base 14, the thorough cleaning of the internal layer screen pack 2 is realized by repeatedly moving back and forth.
Finally it should be noted that:Above example is only illustrating the technical solution of the utility model rather than it is limited
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
