A kind of sewage-treatment plant
Technical field
The utility model is related to technical field of sewage, more particularly, to a kind of sewage-treatment plant.
Background technology
Complex mixture containing organic/inorganic substance and organic matter in sewage, including:(1)Floating and the size solid to suspend
Grain;(2)Gluey and gel diffusate.Sewage disposal is the water quality for being discharged into a certain water body to make sewage reach or reusing
It is required that carrying out the process of purified treatment to it, i.e., decontamination process is carried out to wherein size solid particulate matter, diffusate.
Strainer filtering is purification style most-often used in coarse filtration, and the filtration particulate matter size of which depends on strainer
Aperture size, overall structure is simple, use cost is relatively low, but how to remove the particulate matter on strainer is this kind of filter
Whether design is reasonable and whether can realize the difficult point place of continuity filtering.
Application No. is disclosing a kind of manual backwashing filter in 201310592860.4 utility model patent,
The filter is made of blowdown component, intake antrum, intermediate cavity and filter chamber, and when work, the capping of blowdown component is in intake antrum
The trepanning centre position of bottom two, wastewater inlet are at the inner wall of the central cylinder of intermediate cavity, and filter core import is standard-sized sheet shape
State, drain outlet are closed state, and source water enters inside filter core and is filtered at this time, and clear water comes together in filter core and shell after filtering
Between, it is exported by outlet pipe;When needing to clear up filter core, rotational handle makes one of filter assemblies capping and intake antrum bottom surface
Trepanning center overlaps, and drain outlet is opened, and the clear water between filter core and shell enters filter core, will accumulate in screen wall and strainer
Interior impurity is flushed into blow-off pipe discharge;After filter gauze cleaning is clean, rotational handle can carry out the cleaning of next strainer, directly
To filter core full recovery to normal operating conditions.The filter can carry out backwash and independence under not shutdown status to filter core
Blowdown, but backwash needs manual rotation's handle to send out operation signal, and every time can only a strainer backwashed.

Description of the drawings
Attached drawing 1 is the utility model embodiment one, and attached drawing 2 is the utility model embodiment two, and attached drawing 3 is the utility model
Embodiment three, wherein 1 is babinet, 2 be backwash chamber, and 3 be chimney filter, and 4 be motor, and 5 be leading screw, and 6 be screw, and 7 be limiting section
Part, 8 be filter opening, and 9 be outer tube, and 10 be sewage mouth, and 11 be sewage draining exit, and 12 be filtering water outlet.
Specific implementation mode
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is illustrated.
The utility model discloses a kind of sewage-treatment plants, including accommodate the shell of the device, further include:It is provided with filter opening
8 chimney filter 3, it is sewage draining exit 11 that 3 one end of chimney filter, which is with wastewater inlet, the other end of external connection,;Outside chimney filter 3 extremely
Few one group of backwash chamber 2, backwash chamber 2 set back-flushing water supply part;It is connect with backwash chamber 2, carry backwash chamber
The moving parts that room 2 is moved.Sewage enters chimney filter from wastewater inlet, and drainage was flowed out from filter opening, and granule foreign is blocked on
In filter opening, to avoid filter opening from being blocked, influencing the rate of filtration, backwash chamber moves under moving assembly drive along chimney filter surface
It is dynamic, backwashing water in movement(Cross drainage)Filter opening is washed away, blocks the impurity of filter opening by refunds chimney filter, and from 11 row of sewage draining exit
Go out.
It is on the move to backwash chamber 2, mobile limit is achieved the purpose that using limiting component, two groups are installed on same chimney filter
The above backwash chamber, then ensure that the movement between different groups of backwash chambers does not generate interference by limiting component.
The hydraulic cylinder either piston rod of cylinder hydraulic cylinder or cylinder connection backwash can be used in the power source of moving parts
Chamber also can be used motor driving, the movement of chamber realized by motor-driven transmission parts to drive the chamber to move.
Back-flushing water supply part is that the drainage of crossing in shell is pumped into the water pump of backwash chamber and necessary pipeline
Connection.
The cross-sectional shape of chimney filter is unlimited, can be cylindrical tube or other shapes.
Embodiment one:As shown in Fig. 1, the present apparatus includes babinet 1, and chimney filter is located in babinet 1, and chimney filter 3 is the snake of bending
The un-flexed portion of shape chimney filter, snakelike chimney filter is provided with filter opening 8, and one end of snakelike chimney filter is wastewater inlet, the other end extends babinet 1
Outer formation sewage draining exit 11.
Moving parts includes motor 4, and motor 4 directly or indirectly turn-screw 5, so-called direct-drive, refer to that motor is defeated
Shaft connects leading screw 5, and indirect drive refers to that the power that motor 4 exports passes to leading screw 5 after deceleration, and backwash chamber 2 connects
Connect the screw 6 coordinated with leading screw 5.In this way, leading screw 5 rotates under the drive of motor 4, matched screw 6 drives chamber to realize
Linear movement.
Drainage is crossed for obtain that water quality gradually promotes, in the present embodiment, with the increase with a distance from wastewater inlet, snakelike chimney filter
The diameter of un-flexed portion's filter opening become smaller, with becoming smaller for filter opening diameter, filtering impurities in water particle become smaller and meanwhile cross drainage also by
Gradual change is clear.
Under moving parts drive, backwash chamber is moved along pipe surface, and backwashing water applies certain backwash to filter opening 8
Power is attached to impurity on filter opening under that force, is discharged from sewage draining exit 11 with flow.
Embodiment two:As shown in Fig. 2, it is provided with filtering water outlet 12 in the present embodiment middle case 1, the present apparatus may be configured as
Multi-stage sewage treatment device, the drainage excessively that upper level is disposed enter next stage sewage-treatment plant by filtered water outlet 12
In, i.e., the filtering water outlet 12 of upper level connects the sewage mouth 10 of next stage, and to obtain, quality is better to cross drainage.
Embodiment three:As shown in Fig. 3, the present embodiment middle casing is outer tube 9, and chimney filter is located in outer tube 9, and chimney filter is far from dirty
One end of water inlet extends outer tube and forms sewage draining exit 11, and outer tube also has filtering water outlet 12.Come from wastewater inlet conveying
Sewage enters in chimney filter, crosses drainage and is oozed out from filter opening, and impurity is blocked in filter opening, and is finally discharged from sewage draining exit 11.
This sewage-treatment plant can be multi-stage sewage treatment device, so-called multistage, refer at least double-filtration, every grade from
The drainage of crossing of the discharge of filtering water outlet 12 is inputted by the sewage mouth 10 of next stage, and every grade of outer tube is all provided with sewage draining exit 11.It considers
The variation of particulate matter, with the increase of filtering series, the diameter of filter opening becomes smaller.
The present apparatus is suitable for multiple use, is not only adapted to the industrial wastewater filtering based on particulate contaminant and uses, is further adapted for giving birth to
Waste water filtering purposes living, for example be installed in the foul water tank of road sweeper, ground is washed away with water first in sweeping the floor, then by water
It is picked up from ground, the sewage of recycling enters in foul water tank, and after the present apparatus is handled, crossing drainage can reuse.
Certainly, above description is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
The variations, modifications, additions or substitutions that the those of ordinary skill in art field is made in the essential scope of the utility model, also belong to
In the scope of protection of the utility model.
