Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein preferred
Example is only used for describing and explaining the present invention, and is not used to limit the utility model.
As shown in Figure 1, 2, 3, the utility model rural area dispersed miniature Pig farm wastewater processing unit, including bottom plate 100,
Fixed case 200, Rose Box 300 and storage bin 400, either fixed case 200, Rose Box 300 are disposed on bottom plate 100 also
It is storage bin 400, can be fixed on bottom plate in such a way that screw etc. is detachably connected.
Fixed case 200 and Rose Box 300 can be passed sequentially through after sewage sucking and carries out secondary filter, finally storage bin again
It is saved and is reused in 400.Wherein, step structure 130 is formed on bottom plate 100, storage bin 400 is located at step structure
On 130, so that the height of 400 bottom surface of storage bin is lower than the height of 300 bottom surface of fixed case 200 and Rose Box, so that sewage passes through
After secondary filter, it can rapidly, quickly imported into storage bin 400, prevent line clogging, while being also convenient for storage bin
400 carry out dismounting and change.
Bottom plate 100 is uniformly arranged below with four universal wheels 140, so that the device Integral movable, improves practical
Performance.
Fixed case 200 is internally provided with a rotation bucket 210, and the rotation bucket 210 is funnel-shaped, uniformly opens up on peripheral wall

Connecting hole 121 is offered at center, is rotated and is also equipped with the link block 212 to match with connecting hole 121 on the bottom surface of bucket 210,
So that rotation bucket 210 can be fixedly connected with the mutual tight fit of connecting hole 121 with shaft 110 by link block 212,
When shaft 110 is rotated by motor or other modes driving, it is able to drive rotation bucket 210 and rotates, make to rotate in bucket 210
Sewage rotate and occur centrifugal effect, from rotation bucket 210 on leak hole 211 in fly out, deposit to the bottom of fixed case 200,
Meanwhile centrifugal effect can be improved in funnelform rotation bucket 210.
The shape of the connecting hole 121 and link block 212 is simultaneously not fixed, likewise, enabling to rotation bucket 210 and swivel plate
120, i.e. shaft 110 achieves a fixed connection, and any of synchronous rotation is fixedly connected with mode, should all fall into the utility model protection
Range.
Shaft 100 by motor or the driving rotation of other driving methods is not unique centrifugation protocol yet, it should be appreciated that
, in this step operation, so that the sewage in rotation bucket 210 carries out the key that rotating centrifugal is only the utility model use
Therefore technical solution drives rotation bucket 210 to rotate and makes sewage centrifugation that should also fall into the utility model protection using other modes
Range.
Further, it is additionally provided with revolving door 240 on fixed case 200, which passes through hinge 241 and fixed case
200 realize hingedly, may be provided with handle 242 on revolving door 240.
By using above-mentioned technical proposal, so that needing replacing rotation bucket 210 or to cleaning inside fixed case 200
When, it is only necessary to revolving door 240 is opened, that is, can be taken off rotation bucket 210, replaced or cleaned, further improve whole reality
Use performance.
The bottom of fixed case 200 is connected with the first connecting tube 230, and the top of Rose Box 300 is provided with connection pump 310, the
One connecting tube 230 connects connection pump 310, meanwhile, connection pump 310 is connected to Rose Box 300 by the second inlet tube 320 again.
By using above-mentioned technical proposal, so that the sewage of 200 bottom of fixed case is deposited on after centrifugation, due to connection
The work of pump 310 passes through the first connecting tube 230 respectively and the second inlet tube 320 is flowed into Rose Box 300.
Rose Box 300 is internally provided with filter screen 330, and quartz sand layer 331, filter screen 330 are equipped on filter screen 330
Lower section be provided with deflector 332, the bottom of Rose Box 300 offers through-hole 340, and through-hole 340 is circumscribed with the second connecting tube
350, deflector 332 is whole to be tilted to the through-hole 340 and connects with the second connecting tube 350.
By using above-mentioned technical proposal, so that the sewage into Rose Box 300 can pass through quartz sand layer 331 and filter screen
330 second of filtering, and the second connecting tube 350 is flowed by deflector 332.Wherein, the shape of deflector 332 is not solid
It is fixed, but either which kind of shape, guide functions are collected as long as can satisfy and play water conservancy diversion to sewage.
One end of second connecting tube 350 is connected to Rose Box 300, and the other end protrudes into storage bin 400 and in the vertical direction
It is funnel-shaped.
Sewage after collecting as a result, is collected in storage bin 400 again after secondary filter, and funnel-shaped by head
The second connecting tube 350 fall, it is uniform and steady, it is therefore prevented that sewage blocks in pipeline.
Finally, being each provided with liquid level sensor 500 and alarm 600 in fixed case 200 and storage bin 400, dirt is prevented
Aqueous position is excessively high, and the capable of emitting alarm when exceeding early warning liquid level, further improves whole practical performance.
The working principle of the utility model is: fluid suction head 225 is protruded into sewage, the running water suction of pulsating pump 223, sewage is logical
It crosses telescopic pipette 224 and the first inlet tube 220 enters in rotation bucket 210, the shaft being fixedly connected with rotation bucket 210
110 are driven by motor rotation and rotation bucket 210 are driven to rotate, and rotate the sewage in bucket 210 and centrifugal effect occur and through rotating bucket
Leak hole 211 on 210 peripheral walls, which flies out, deposits to the bottom of fixed case 200.At this point, 310 fortune of connection pump at 300 top of Rose Box
Make, enters the sewage for being deposited on 200 bottom of fixed case in Rose Box 300 by the first connecting tube 320 and the second inlet tube 320
Portion, and collected after the secondary filter of quartz sand layer 331 and filter screen 332 inside Rose Box 300 by deflector 332,
It flows into storage bin and is stored across through-hole 340 and the second connecting tube 350.
In the above-described embodiment, it is allowed the device in several cases using the design of telescopic pipette 224
Soil pick-up is carried out, centrifugal effect can be improved in funnelform rotation bucket 210, and rotation bucket is protruded into the water outlet 222 of the first inlet tube 220
It can prevent the sewage direct emission without first time centrifugal treating from depositing to 200 bottom of fixed case in 210, using revolving door 240
Design can facilitate to rotation bucket 210 dismantled, cleaned and replaced；
Meanwhile using the secondary filter of a centrifugal filtration and quartz sand layer 331, filter screen 330, filtering effect can be improved
Fruit, lifting sewage quality are pooled in storage bin 400 finally by deflector 332 and the second connecting tube 350, and head is in funnel
The second connection end 350 of shape can prevent sewage from blocking in pipeline；
Design has step structure 130 on bottom plate 100, and storage bin 130 is located in step structure, so that sewage passes through secondary mistake
After filter, it can rapidly, quickly imported into storage bin 400, prevent line clogging, while be also convenient for carrying out storage bin 400
Dismounting and change.
The bottom of bottom plate 100 is provided with multiple universal wheels 140, so that the device Integral movable, in fixed case 200 and storage
It deposits and is each provided with liquid level sensor 500 and alarm 600 in case 400, prevent sewage level excessively high, and exceeding early warning liquid level
Capable of emitting alarm when height, further improves whole practical performance, not only ensure that hygienic and clear in small-sized pig farm
It is clean, it more ensure that the health of pig.
In conclusion the utility model structure is simple, practical performance is high, can be in the dispersed miniature pig farm of rural area
Sewage carries out secondary filter and collects, and recycles and reuses to realize, reduces production cost.
Finally, it should be noted that being not limited to this reality the foregoing is merely the preferred embodiment of the utility model
