Description
Technical field
The present invention relates to liquid handling technologies, and in particular to a kind of filtering of liquid and purification device.
Background technique
Filter is a kind of common equipment, is widely used in various industries.Existing filter is deposited in use
In following point: being easy blocking, need to shut down periodic cleaning or backwash；Very burden so is caused to user, that is, is influenced
System worked well, and backwash also causes the consumption of a large amount of water.
Summary of the invention
Insufficient for existing filter, the present invention provides self-cleaning filter.The equipment operation is simple, land occupation does not produce less,
Raw cleaning waste water, can longtime running do not block, remove stop cleaning worry from；It can be used for the high-precisions filtration field such as cartridge filter
Institute.
To realize above-mentioned target the technical scheme of the present invention is realized as follows:
Self-cleaning filter, including water inlet pipe, filling body, suspended particulate, multiple groups filter core, triple valve, backwash water tank, water outlet
Water tank, outlet pipe, backwash pump, blow-down pipe, sewage pipe, control system composition.It is characterized in that: tank body is vertical structure, it can
To bear pressure；Water inlet pipe is connect on filling body top with tank diameter tangentially obliquely；It fills and multiple groups filter core, filter core is housed in vivo
Other end closing open at one end；It is wrapped in around filter core to be suspended particle, suspended particle density is less than fluid density；Every group of filter
The open end of core connects a triple valve, and one connection of other two interface of triple valve backwashes water tank, another is connected out
Water tank；Backwash water tank is all located at water tank out and fills body top；Backwash pump one end is connect with water tank out, the other end
It is connect with backwash water tank；Outlet pipe is connect with water tank out；Blow-down pipe is filling body top, and sewage pipe is in the bottom for filling body.
The N+1 group filter core of the self-cleaning filter can be single branch filter core, be also possible to the combination of more filter cores.Filter core
It can be various sieves, powder sintered, hollow fiber cartridge etc., such as: stainless steel sintered meshwork filter core, powder of stainless steel sintering filter
Core, titanium powder sintered filter core, ceramic membrane filter core, PE pipe filter core, PP pipe filter core, various materials hollow-fibre membrane and membrane tube.
The suspended particulate of the self-cleaning filter package filter core, the density of suspended particulate are less than liquid being filtered；It is outstanding
Floating particles can be the assembly of various plastics, haydite, active carbon, float stone etc. and above-mentioned material and other a variety of materials, shape
Shape is unlimited, and the minimum dimension of individual particle cannot be less than the minimum dimension of cartridge surface aperture.
The triple valve of the self-cleaning filter can be it is electric and pneumatic, be also possible to backwash triple valve.
The self-cleaning filter self-cleaning control can be time control and be also possible to pressure difference control, flow control, instead
Flush water pump and triple valve are automatically performed the self-cleaning of filter under the operation of control system.
Beneficial effects of the present invention: land occupation does not block less, or not is free of cleaning, and filter can long-term continuous operation.
Detailed description of the invention
Fig. 1 is the general structure schematic diagram of self-cleaning filter of the present invention,
It is as shown in the figure: fill body 1, suspended particulate 2, multiple groups filter core 3, water inlet pipe 4, outlet pipe 5, go out water tank 6, triple valve 7,
Backwash water tank 8, backwash pump 9, sewage pipe 10, blow-down pipe 11.
Specific embodiment
Below in conjunction with attached drawing, the invention will be further described.
Embodiment 1
As shown in Figure 1, self-cleaning filter of the present invention includes: to fill body 1, suspended particulate 2, multiple groups filter core 3, water inlet pipe 4, outlet pipe
5, go out water tank 6, triple valve 7, backwash water tank 8, backwash pump 9, sewage pipe 10, blow-down pipe 11.Water inlet pipe 4 and filling body 1
Diameter is oriented in a tangential direction connection；Multiple groups filter core 3, which is evenly arranged on, to be filled in body 1, the corresponding triple valve 7 of every group of filter core 3, triple valve 7
One, other two interface connect with water tank 6 out, another connect with backwash water tank 8；Water tank 6 and backwash water tank out
8 are all located at the top for filling body 1；Backwash pump 9 is connected respectively at water tank 6 out and backwash water tank 8；Sewage pipe 10 is filling body
1 bottommost, blow-down pipe 11, which is located at, fills 1 top of body.
Its workflow of self-cleaning filter of the present invention is: the liquid for needing to filter enters tank body 1 from 4 tangent line of water inlet pipe,
It is moved down on 1 internal edges of tank body rotation side；Fill body 1 in suspended particulate 2 also make rotating motion under the drive of liquid and
Friction is generated with 3 outer surface of filter core；Liquid is entered inside filter core 3 by filter core 3 and converges to out water tank 6, eventually by out
The discharge of water pipe 5 fills body 1；Suspended matter a part in liquid is blocked the suspended particulate 2 moved in 3 outer surface of filter core and touches
And fall off, 1 bottom of body is filled by the discharge filling body 1 of sewage pipe 10 than being deposited to for liquid weight, and float to lighter than liquid fills on body 1
Portion fills body 1 by the discharge of blow-down pipe 11；The suspended matter for remaining in filter core 3 can mostly be filtered until blocking over time more collecting
Core leads to flow-reduction, needs to carry out the backwash of this group of filter core 3 at this time；When a certain group of filter core flow-reduction is to certain value,
Triple valve 7 on this group of filter core 3 will carry out commutation action, and the pipeline of this group of filter core 3 and water tank 6 out is cut off at this time, and anti-
8 pipeline connection of flush box, filtered liquid enters recoil by going out water tank 8 under the action of backwash pump 9 at this time
Water tank 6 enters back into the inside of filter core, by this group of 3 inside of filter core flowing outward, to keep the suspended matter on 3 surface of filter core de-
It falls；, after a period of time, triple valve 7 is returned to working condition, this group of filter core 3 enters working condition again, so completes
The backwash of filter core 3；When certain group filter-core back-flushing is washed, other filter cores are unaffected, are still within working condition；So realized
The online self-cleaning of filter.Self-cleaning filter, which needs periodically to open blowdown valve, is discharged the sludge filled in body 1 by sewage pipe 10
And grain slag.Self-cleaning filter need periodically open blow-down pipe 11 valve discharge suspended matter and
The enabling signal of triple valve 7 can be filter inlet outlet pressure differential, be also possible to the variation of filter outlet flow,
It can also be the preset time.The working time of triple valve was controlled by the preset time.
The job control of backwash pump 9 is carried out according to backwash tank pressure.When the pressure of backwash water tank 8 is lower than
Water pump starts when setting value, and when the pressure for backwashing water tank 8 reaches setting value, water pump is automatically stopped work.
