Description
Technical field
The present invention relates to filter, more particularly to a kind of self-cleaning filter.
Background technology
Filter is generally filtered the fluid with impurity by strainer, is more than the impurity of the mesh of strainer by strainer
It stops detaching with fluid, to realize the filtering to fluid, but since strainer is generally mounted to filter interior, cleaning filter
Net is more troublesome, and mesh can be caused to block without cleaning strainer, be reduced the filter efficiency of filter.Self-cleaning filter is a kind of
Need not dismounting strainer and the filter that strainer is cleaned out can be about to by filter interior structure certainly, but on the market from clear
It washes after filter only allows water punching to brush one times strainer the cleaning of strainer and water, cleaning performance difference and waste water resource is just discharged.
Notification number is that the Chinese patent of CN104069665B discloses a kind of filter with self-stripping unit, including mistake
Filter shell, filter housings inside install inner drum, filter core are arranged inside inner drum；In the top of filter housings, installation is clear
Seat is washed, toilet seat is equipped with the first water inlet, water outlet and wastewater outlet, close to the first water inlet side in toilet seat inner cavity
Formed into hydrospace, hydrospace formed out close to water outlet side in toilet seat inner cavity, into hydrospace and go out hydrospace it
Between pedestal is set；Moving block is set in the inner cavity of pedestal, and the upper end of moving block connects rotating bar, and rotating bar stretches out toilet seat；
The first through hole and the second through hole are radially respectively set on moving block, the first through hole and the second through hole are respectively facing
Not homonymy, the second through hole are connected to the inner cavity of filter core；Go out hydrospace side towards into hydrospace side and direction on pedestal
Top be equipped with and can be connected into hydrospace, the first through hole and the second water inlet for going out hydrospace, it is empty towards water inlet on pedestal
Between the lower section of side be equipped with and can be connected to third water inlet into hydrospace and the second through hole；In the bottom of toilet seat close to water outlet
Water in-out port is set at mouthful, and water in-out port is connected to the outside of filter core and goes out hydrospace；The wall thickness of filter core from top to bottom gradually increases,
Form up big and down small pyramidal inner cavity.
The filter makes the second through hole on moving block with the third water inlet on pedestal in company by rotating rotating bar
When logical state, the first through hole on moving block and the second water inlet on pedestal are in disconnected state, and water inlet is by the first water inlet
It mouthful flows into hydrospace, and flows into the inner cavity of filter core by the third water inlet on pedestal, by filter core by the impurity in water inlet
Filtering is clean, and water purification reaches the outside of filter core by filter core, then drains into out hydrospace by water in-out port, and by water outlet by water purification
Discharge is for using；When cleaning strainer, rotating bar is rotated, makes the first through hole on moving block be in the second water inlet on pedestal
When connected state, the second through hole on moving block and the third water inlet on pedestal are in disconnected state, and the inner cavity of filter core
It is connected to wastewater outlet, water inlet is flowed by the first water inlet into hydrospace, drains into out hydrospace by the second water inlet, then by going out
For using, water inlet flow to the outside that water in-out port enters filter core by being discharged space for mouth of a river discharge, by being flowed into filter core on the outside of filter core
Chamber, to be cleaned to filter core, the sewage after cleaning is discharged by wastewater outlet.But the filter is in the process of cleaning strainer
In, water is the cleaning completed to filter core by flowing into filter core inner cavity on the outside of filter core, and the impurity being adhered on strainer is still adhered to
On strainer, cleaning performance is poor, has much room for improvement.
Invention content
In view of the deficienciess of the prior art, the technical purpose of the present invention is to provide a kind of self-cleaning filter, have

It turns to intake antrum 11 when through-hole 911 is detached with straight slot 921 with water chamber 13 to be isolated, to realize through-hole 911 and straight slot 921
Connection and dislocation, and the area that can be connected to straight slot 921 to through-hole 911 is precisely adjusted, to intake antrum 11 and water outlet
Uninterrupted between chamber 13 is precisely adjusted.
As shown in Figure 2 and Figure 4, sewage pipe 16 is semi-cylindrical, and the flow-limiting valve 8 includes being fixedly connected with sewage pipe 16
One section of sewage pipe 16 that the limiting plate 81 of semi-cylindrical, the limiting plate 81 and limiting plate 81 connect is combined into cylinder, the limit
Position plate 81 and sewage pipe 16 are equipped with cylindrical current limiting plate 83, and the current limiting plate 83 is provided with semicircular metering hole 831, adjust
The rotation of the mobile drive current limiting plate 83 of locking nub 84 slides rotatable current limiting plate 83 by adjusting block 84 in regulating tank 82, when
Sewage pipe 16 is closed when metering hole 831 turns to 81 inside of limiting plate, the sewage when metering hole 831 turns to 16 inside of sewage pipe
Pipe 16 is opened, and to realize the accurate adjusting to current limiting plate 83, makes the area that metering hole 831 is located in sewage pipe 16 that can carry out essence
Thin adjusting, and then realize the accurate adjusting to the uninterrupted of sewage pipe 16.
Operation principle：
When crossing drainage using filter, close sealing valve 9 and flow-limiting valve 8 and remove sealing-plug 151 from outlet pipe 15, water from
Water inlet pipe 14 enters after intake antrum 11 and enters filter chamber 12 through filter screen 3, realizes and filters for the first time, for the first time the impurity position of filtering
In on strainer 3 and in intake antrum 11, water is realized second and is filtered from the bristle gap that filter chamber 12 enters filtering brush 4, second
The impurity of secondary filtering is located in filtering brush 4 and in filter chamber 12, and water enters from the bristle gap of filtering brush 4 through filter screen 3
Water cavity 13 realizes that third time filters, and the impurity of third time filtering is located on strainer 3 in filter chamber 12, and final water is from water chamber
13 are flowed out by outlet pipe 15, and a small amount of citric acid and disodium EDTA are dissolved in water and make the weight in water during this period
Metallic element deposits, and chemical filtering is carried out to water.
When cleaning strainer 3, outlet pipe 15 is blocked using sealing-plug 151, stops water inlet, is then turned on sealing valve 9 and flow-limiting valve 8
It drives the impurity for sinking to bottom to be flowed out from sewage pipe 16 in water in intake antrum 11, then starts to intake and open cylinder 21, with this
Turn the flow of flow-limiting valve 8 down simultaneously, cylinder 21 drives moving member 7 to be moved back and forth along the length direction of lead screw 6, moving member 7
Rod set 5 is driven to be moved along the length direction of lead screw 6, it is to turn that rod set 5 drives filtering to brush 4 with lead screw 6 while mobile
Axis is rotated, to drive citric acid and disodium EDTA to be dissolved in water, citric acid and disodium ethylene diamine tetraacetate
Salt promotes the incrustation scale dissolving for being adhered to strainer 3 and filtering brush 4, and filters what brush 4 was moved in the length direction along lead screw 6
It is carried out at the same time rotation, the bristle of filtering brush 4 repeatedly washes away strainer 3, and filters brush 4 and drive flow rotation while rotation
Turn, enhances souring of the flow to strainer 3, and the flow that the bulk impurity reunited can also be rotated is separated into small-sized impurity,
Filter is left to be driven from sewage pipe 16 by flow.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, people in the art
Member can as needed make the present embodiment the modification of not creative contribution after reading this specification, but as long as at this
It is all protected by Patent Law in the right of invention.
