Description
Technical field
The present invention relates to a kind of filters, and in particular to it is a kind of can automatic cleaning filter core filter and its working method.
Background technique
Its filter core of traditional filter is easy to the blocking by dirt, causes the decline of flow, therefore when build up of dirt arrives
Certain degree just needs to get off cartridge removal to clean, it is made to restore original flow, such as application No. is
201120398365.6 Chinese patent, cleaning filter core was both time- and labor-consuming, and many troubles are brought to user.
Application No. is 201120421200.6 Chinese patents to disclose a kind of water filter structure with self-cleaning function, should
Hairbrush is mounted in Columned filter core in patent, water is flowed from filter core Inside To Outside when filtering, drive of the hairbrush in water
Lower rotation plays self-cleaning function to remove impurity.The structure of the patent can be used for more conventional filtering, and cannot be used for
In special filtering, in the case where such as more demanding to the degree of filtering, and the essence to be formed a film with substances such as resin or activated carbon
In filtering technology, i.e., the filter membrane of the substances such as one layer of resin or activated carbon is first formed on the strainer of filter core in impurity screening, so
Be filtered again afterwards, which cannot accomplish this point, as long as because its hairbrush water flowing will rotary motion, resin can not be made
Or the substances such as activated carbon form one layer of filter membrane on the strainer of filter core.
Summary of the invention
It is an object of the invention to overcome the above deficiencies in the existing technologies, and providing a kind of design reasonably can be certainly
The filter and its working method of dynamic cleaning filter core, the filter core of filter can be carried out automatically without dismantling filter core by being able to achieve
Cleaning reduces because of time and manpower consumed by cleaning filter core, reduces use cost.
Technical solution used by the present invention solves the above problems is: it is a kind of can automatic cleaning filter core filter, including
Shell and filter core, the filter core setting is inside the shell；It is characterized in that, further including hairbrush, spray tube and total outlet pipe；The hair
The two sides of filter core are arranged in brush, and fix on the rotary shaft, and the hairbrush is contacted with filter core, and filter core is arranged in the rotary shaft
Middle part；The top of filter core is arranged in the spray tube, is equipped with spray head on the spray tube；The total outlet pipe is arranged in shell
Lower section, the total outlet pipe is connected to filter core；Inlet valve, blowdown valve and blow valve, the water inlet are provided on the shell
Valve and blowdown valve are separately positioned on the both ends of outer casing bottom, and the top of shell is arranged in the blow valve.
Furthermore, two outlet pipes are connected on the filter core, the outlet pipe is by the U-tube with valve and always
Outlet pipe connection.
Furthermore, shower valve is installed on the spray tube, outlet valve is installed in the total outlet pipe.
Furthermore, the shell is cylindrical enclosure structure, and the shell includes upper cover and lower case,
The lid and the detachable cooperation of shell.Upper cover can open, and be easily installed, repair and replace filter core and hairbrush.
Furthermore, the filter core be disc-shaped screen net structure, the filter core be provided with it is multiple, on each filter core
It is provided with hairbrush.
It is a kind of as described above can automatic cleaning filter core filter working method, which is characterized in that the work side
Method is as follows: opening inlet valve and outlet valve, closes blowdown valve and blow valve, the water containing impurity enter shell by inlet valve
Inside, in the water flow filtration core containing impurity, impurity on filter core, after filter element filtering, is done by the silk screen shelves on filter core
Net water is pooled to total outlet pipe from outlet pipe, is finally discharged by outlet valve, completes filter process；When the amount of impurity on filter core
When gathering certain degree, the blocking of filter core will be caused to decline flow, at this moment just need to clean filter core；By inlet valve and
Outlet valve is closed, and blow valve is opened, and the inside of shell is still full of water at this time, opens the motor for driving rotary shaft rotation, hairbrush
It is rotated under the drive of rotary shaft, filter core is fixed due to hairbrush and filter core contact, with the rotation of hairbrush, on filter core
Impurity brushed in water, later, open blowdown valve, sewage from sewage pipe be discharged, shower valve is finally opened, to filter core and hairbrush
Spray cleaning is carried out, completes the automatic cleaning of filter core in this way.
Furthermore, when opening the motor for driving rotary shaft rotation, hairbrush carries out 360 ° under the drive of rotary shaft
Rotation.
Compared with prior art, the present invention having the following advantages that and effect: compared with traditional filter, the present invention passes through
Improvement in structure is realized and can be carried out the filter core of automatic cleaning strainer without dismantling filter core, to reduce because cleaning is filtered
Time and manpower consumed by core reduce the cost used.Filter eliminates the process of the disassembly, cleaning of filter core, can drop significantly
Low labor intensity and shortening scavenging period, have apparent economic value.
Hairbrush is mounted on two lateral surfaces of filter core, and the hairbrush of multiple filter cores is mounted on the same axis, and one acts as
Circular motion scrubs multiple filter cores simultaneously, it can be achieved that more filter element filterings.Hairbrush moves under the drive of motor, is needing to clean
It is just moved when filter core, this can make filter in special filtering technique, such as with substances such as resin or activated carbon
In the refined filtration technique of film forming, i.e., the mistake of the substances such as one layer of resin or activated carbon is first formed on the strainer of filter core in impurity screening
Then filter membrane is filtered again, can achieve special refined filtration effect.
