Description
Technical field
The present invention relates to the mobile filter fields of the filter element during filter operation, in particular to a kind of strainer
Detachable Microfilter.
Background technique
Microfilter is a kind of the screen to filtrate device, and the machinery for being mostly used in the separation of sewage disposal system prior solid-liquid is set
It is standby.
Rotary drum has strainer, and when rotary drum is placed in water work, 2/5 strainer is submerged in water, and processed waste water is along axial
It into rotary drum, is flowed out through sieve, impurities in water is retained in drum barrel upper filter screen inner face.When the impurity being trapped on strainer is turned
Drum is flushed in dirt discharge groove by the backwashing water on the outside of sieve and is flowed out when taking top to, realizes solid, liquid two-phase separation, backwash by
Timer or liquid level sensor control.Filtered water flows back into pond again to be recycled.
For Microfilter when entering working condition, when the water containing suspended matter particle enters in drum microfiltration machine, suspended matter is just
It can be retained by stainless steel filtering net, the water without suspended matter enters reservoir after filtering.It suspends when in the roller of drum microfiltration machine
When object accumulates to certain amount, strainer permeable amount can be caused to decline, cause water level in roller to rise, when water level rises to setting
When high water level, automatic Control Systems of Liquids Height work, at this point, anti-flushing water pump and Rolling motor automatically turn on simultaneously, anti-ejected wash water
Back cleaning system of the high pressure water of pump through Microfilter carries out high-pressure wash to the drum strainer of rotation, is blocked on drum strainer
Suspended matter flows into sewage collecting groove and is discharged again through sewage pipe under the flushing of high pressure water.After filter gauze cleaning is clean, drum strainer
Permeable amount rise, the water level decreasing in roller, when water level is down to the low water level of setting, anti-flushing water pump and Rolling motor will
It is automatically stopped work, Microfilter enters new round working cycles again.
During the filtration process, the water containing suspended matter particle can have very strainer during entering Microfilter from two sides
Big impact, strainer mostly by groups of metal filaments at, damage is easily deformed under biggish hydraulic pressure, more damage relatively frequently, existing filter
It is typically integrally molded molding between net and the bracket of Microfilter, it is pretty troublesome when repairing and replace.
Authorization Notice No. is CN204307435U, in a kind of entitled utility model patent of the lauter tub of rotary drum Microfilter
Although cylinder and filter screen and dismountable, cooperate terylene filter screen, it is slightly smaller, and using bonding by the way of,
Installation effect is poor, and Microfilter is chronically in water, and is glued for a long time by the impact of water flow and the flushing of high-pressure cleaning device
It is easy cracking at conjunction, influences filter effect.
Summary of the invention
The main purpose of the present invention is to provide a kind of detachable Microfilter of strainer, to solve strainer in the prior art and micro-
Integrally molded molding between the bracket of filter, strainer intensity is poor, and maintenance and replacement difficulty and filter screen part break down will be whole
Body replacement, the high problem of replacement cost.
To achieve the goals above, the following technical solution is employed by the present invention:
A kind of detachable Microfilter of strainer comprising rack, roller, net-filter assembly, back purge system and driving device,

Several filtering grids are formed between ring and connecting component；
Support ring outer surface is provided with supporting vertical plate, and supporting vertical plate is vertical with support ring surface, supporting vertical plate and support ring
It is integrally formed, section is T-shaped；
Net-filter assembly includes strainer fixed frame and filter screen, and filter screen is fixed on strainer fixed frame；
Fixed plate is installed in connecting component, net-filter assembly is fixed on roller by fixed plate.
Further, connecting component includes plate and vertical plate, and plate both ends connect support ring, and vertical plate is welded on plate,
It is rectangular with plate, it is welded on vertical plate in the middle part of fixed plate.
Further, fixed plate bends certain angle from centre, and the both ends of fixed plate are provided with mounting hole.
Further, strainer fixed frame is arc-shaped, and strainer fixed frame is fixed on by the mounting hole jackscrew in fixed plate
On plate.
Further, the size of strainer fixed frame and the size of filtering grid are adapted.
It further, further include liquid level sensor, liquid level sensor is vertically-mounted on the rack, becomes for sensed water level
Change.
The invention has the following advantages:
(1) the support ring surface of the detachable Microfilter of strainer involved in the invention is provided with supporting vertical plate, support ring with
Supporting vertical plate uses integrally formed processing method, can both reinforce the roller of Microfilter, increases roller intensity, and can be to filter
The certain supporting role of screen component, so that structural stability is stronger.
(2) the detachable Microfilter of strainer involved in the invention, is provided with fixed plate and net-filter assembly, and strainer passes through filter
Net fixed frame is removably mounted in fixed plate, only needs replacing relevant strainer group in the case that strainer has damage in part
Part, maintenance and replacement are simple, and work efficiency is high, and replacement cost greatly reduces.
