Embodiment
With reference to the accompanying drawings and examples, the present invention is expanded on further.In the following detailed description, only explanation is passed through
Mode describes some one exemplary embodiments of the present invention.Undoubtedly, one of ordinary skill in the art will recognize,
In the case of without departing from the spirit and scope of the present invention, described embodiment can be repaiied with a variety of modes
Just.Therefore, accompanying drawing and description are inherently illustrative, are not intended to limit the scope of the claims.
As depicted in figs. 1 and 2, prawn culturing recirculated water solid-liquid separation system, including micro-filtration pond 10, in the micro-filtration pond 10
Rotary drum Microfilter 20 is installed, the top of the rotary drum Microfilter 20 is provided with back purge system 30, and the rotary drum declines
It is integrally disposed in filter 20 to have blowdown apparatus 21, dirt collection, dirt eliminating function are such as realized using dirt discharge groove structure；The rotary drum declines
The water inlet port of filter 20 is provided with water level sensor 40, and the signal output part of the water level sensor 40 is connected with PLC controls
Device 50, the control of PLC 50 connect the rotary drum Microfilter 20 and back purge system 30.
In high density circulating water cultivation, it is necessary to processing water in organic particulate pollutant：Residual bait accounts for 30%, excreta
Account for 50%, other pollutants and account for 15%；Because organic particle concentration is not high, and without the performance of cohesion, precipitating
Shapes and sizes will not be changed in journey, also do not polymerize, so belonging to free sedimentation.These pollutants can influence circulating water treatment system
The subsequent filter of system, therefore sedimentation basin 70 is preferably provided in the upstream in the micro-filtration pond 10, the upstream of sedimentation basin 70 is culturing pool 60；
The treatment sewage so discharged from culturing pool 60 is introduced into sedimentation basin 70, allows organic particle therein to precipitate,
To reduce the influence to follow-up water treatment procedure.
Wherein, the culturing pool 60 is square circular pond (having arc angling at the corner in square pond), and its bottom of pond is tapered
Structure, the gradient are advisable with 2%, and the pool aottom center of culturing pool 60 is provided with culturing pool sewage draining exit 61；So by pond shape design with
And conical tank bottom structure, coordinate the eddy flow sparge pipe (or surge machine) above the face of pond, feed residual bait and shrimp aquaculture mistake can be caused
In journey caused shrimp excreta with water ceaselessly circulation during, along bottom of pond slope under circulation tangential force and Action of Gravity Field
The culturing pool sewage draining exit 61 that gradual eddy flow enters pool aottom center is spent, beneficial to the thorough dirt collection of bottom of pond and blowdown, so as to reduce water
Oxygen consumption, effectively avoid organic matter accumulation for a long time, decompose and polluted water.
The bottom of pond of the sedimentation basin 70 is provided with the sedimentation basin water inlet 71 connected with culturing pool sewage draining exit 61, and discharge
The sedimentation basin pollution discharge mouth 72 of dirt, the top of the sedimentation basin 70 are provided with sedimentation basin delivery port 73, the sedimentation basin delivery port
73 are connected with the water-in flange 27 of the rotary drum Microfilter 20.
With reference to figure 2, the rotary drum Microfilter 20 includes frame 22, and filter drum is rotatablely equipped with the frame 22
23, filter screen is set with the filter drum 23, is provided with water-in flange 27 in the one end of filter drum 23, the filter drum 23 connects
It is connected to drum drive.Wherein, the drum drive includes drum drive motor 24, the drum drive motor 24
Output end is provided with travelling gear 25, and the end of the filter drum 23 is provided with cylinder drive gear 26, the drum driven
Gear 26 is meshed with the travelling gear 25.
During work, sewage is flowed into filter drum 23 naturally by water-in flange 27, is flowed out after two layers of strainer filtering,
Solid dirt in water can be trapped on filter screen；When water level rises to setting height, illustrate solid on the inside of the filter screen of Microfilter
Particle is more, blocks most of mesh so that water inlet front end water level rises, now the output signal of water level sensor 40, PLC controls
The control of device 50 starts drum drive motor 24 and high pressure backwash pump, and drum drive motor 24 drives filter drum 23 to drive filter
Online dirt is rotated, and when dirt passes through 23 surface of filter drum, dirt is flushed to blowdown apparatus 21 by back purge system 30
In, flow out filter drum.
In the present embodiment, the back purge system 30 includes the flushing pipe 31 being connected with high pressure backwash pump, institute
The setting parallel with the axis of the filter drum 23 of flushing pipe 31 is stated, the bottom of the flushing pipe 31 is provided with some sprays
Mouth 32, by the way of press water discontinuously backwashes, the solid suspension particle rinsed out passes through blowdown for the cleaning of such filter screen
Groove is discharged.
The present invention realizes culture of Penaeus vannamei mistake by the Automated condtrol system such as water level sensor, PLC
Excrement and the work of the automatically collecting of feed residual bait, have liberated labourer, have improved production efficiency in journey.
The schematical embodiment of the present invention is the foregoing is only, is not limited to the scope of the present invention.It is any
