Description

The detachable Microfilter of strainer
Technical field
The utility model relates to the mobile filter fields of the filter element during filter operation, in particular to one kind The detachable Microfilter of strainer.
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.
Utility model content
The main purpose of the utility model is to provide a kind of detachable Microfilters of strainer, to solve strainer in the prior art Integrally molded molding between the bracket of Microfilter, strainer intensity is poor, and maintenance and replacement difficulty and filter screen part break down just Want integral replacing, the high problem of replacement cost.
To achieve the goals above, the following technical solution is employed for the utility model:

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 utility model has the following beneficial effects:
(1) the support ring surface of the detachable Microfilter of strainer involved in the utility model is provided with supporting vertical plate, support Ring and supporting vertical plate use integrally formed processing method, can both reinforce the roller of Microfilter, increase roller intensity, and can be with Give net-filter assembly certain supporting role, so that structural stability is stronger.
(2) the detachable Microfilter of strainer involved in the utility model, is provided with fixed plate and net-filter assembly, and strainer is logical Filter screen fixed frame is removably mounted in fixed plate, only needs replacing relevant strainer in the case that strainer has damage in part Component, maintenance and replacement are simple, and work efficiency is high, and replacement cost greatly reduces.
