Description
Technical field
This utility model is related to environmental protection field of water treatment equipment, especially a kind of drum type accurate filter.
Background technology
Accurate filter is to make float by certain porous medium using gravity or pressure reduction, is cut solid particle
Stay, realize the machinery that solid, liquid is efficiently separated in suspension.The accurate filter of prior art is more to be set using fibre turntable filter chamber
Standby, using the design structure of the internal water outlet of outside water inlet, fiber filter piece is erect on central water outlet cylinder, and back washing device is pacified
Fiber filter piece both sides are mounted in, by outer side inflow, current flow into central water outlet after the filtration of fiber filter disc to water during real work
Cylinder, so as to cause filtration flow-rate slow, filter area is little, and fiber filter cloth easily piles up the shortcoming of float cooperating microorganisms, makes for a long time
With the easy residual soil of filter cloth, microorganism, so as to cause not wash clean clearly, filtering surface is damaged, situations such as filtering accuracy does not ensure；And
Filter cloth is installed on nylon support frame, is conducted oneself with dignity very heavy, and operating load is big, and equipment loss is serious.
Utility model content
The applicant is for these shortcomings in above-mentioned existing production, there is provided a kind of drum type accurate filter rational in infrastructure,
So as to substantially increase filter area, filtering accuracy is higher and service life is longer, and circle drum type cartridge filter is big using central supported
The support strength of equipment is increased greatly, the operating load of equipment is greatly reduced, be increased service life.
The technical scheme adopted by this utility model is as follows：
A kind of drum type accurate filter, including the cartridge filter of a revolution, cartridge filter is the cylinder for justifying drum type, and cartridge filter leads to
Cross central support shaft to be supported in frame, central support shaft two ends are provided with bearing；Water inlet is arranged on the open-position-side of cartridge filter,
Sewage enters the inside of cartridge filter；Driving means drive cartridge filter slowly to rotate by drive mechanism；Flush pipe is arranged on filtration
Cylinder top outer, dreg-accepting hopper is arranged on the inside of cartridge filter, below flush pipe.
Further improvement as above-mentioned technical proposal：
Backwashing pump is arranged on the outside of equipment, directly takes water after filter flushing filtering net from filter interior.
It is removable type cover plate above the flush pipe.
Single filter element using 304 rustless steel tabula rasa punchings as filter screen supporting module, and coat adopt material for
The filter screen that 316 stainless mesh grids are made.
Dreg-accepting hopper is supported by central support shaft, and is communicated to slag-drip opening by the middle part pipeline of central support shaft.
The beneficial effects of the utility model are as follows：
Single filter element of the present utility model is the supporting module using the punching of rustless steel tabula rasa as filter screen, and structure is closed
Reason, it is achieved that the standardization of filter screen module, and the skeleton that is made of overall punching has, and intensity is high, impact-resistant feature.Filter
Net adopts material for 316 stainless mesh grids, and corrosion resistance resistance to impact is significantly larger than general fibre filter cloth, in long-term work
In be difficult because of corrosion, damaged and break down, filter screen service life is most long up to 2 years, and screen replacing is convenient, and independent mesh sheet can be only
Vertical dismounting, and do not affect other filter screens.
This utility model is greatly reduced the operating weight of cartridge filter, can be born using the design of intermediate supports intermediate transmission
The lotus continual method of operation for a long time, substantially increases the service life and reliability of equipment, due to filter cylinder rotating speed slow, center
In support, floating bearing is almost without abrasion.
High treating effect of the present utility model, the loss of flood peak are less than 30cm, and effluent quality ss is less than 10mg/L.According to process
The big I of the water yield flexibly increases multiple filter units, processes the water yield greatly, and filtering accuracy is high, automatization's effect is good.
This utility model is can be directly mounted at without the need for embedded foundation on level land, and rinse-system is installed in the outer of filter element
Side, developing result are good, and are provided with level sensor, can induction level height voluntarily running equipment, automatization's effect is good.Punching
Decontamination water consumption is little, the light removal of contamination of backwash water under high pressure.Water used took from water after filter, and water consumption is the water yield for processing
0.1%, far below the water consumption of other similar filters 3% ~ 5%, mitigate the burden of backwash waste later stage process.
