Embodiment
Embodiment 1：Chemical experiment as shown in Figure 1 solid-liquid cyclic separation device, including casing 1, the first water pump 17 and second
Water pump 18, water purifying tank 10 and filtration system etc..
Filtration system includes caching case 3, inclined-plane case 5, negative pressure chamber 8 and return-air room 15 etc..
First water pump 17 passes through the mixed liquor in casing 1 in the extraction of efferent duct 2 to caching case 3.
The caching bottom of case 3 is connected by house steward 4 with the upper end entrance of inclined-plane case 5, and inclined-plane case 5 is a slant setting and solid
Fixed flow-guiding channel, preferably inclined rectangular box, its upper end is entrance, and lower end is outlet.At least the bottom surface of inclined-plane case 5 is set
It is calculated as inclined-plane.Inclined-plane small opening 6 is provided with the middle part of the ramped bottom surface of the inclined-plane case 5, is set positioned at the downstream position of inclined-plane small opening 6
There is the first screen pack 7, the underface of inclined-plane small opening 6 is provided with spoil disposal passage 11, the bottom of spoil disposal passage 11 is mixed by muddy water
Connected after closing chamber 12 with blow-off pipe 13.
The outlet at bottom of inclined-plane case 5 is connected with negative pressure chamber 8, and negative pressure chamber 8 is connected by the road of efferent duct 2 with water purifying tank 10.
The bottom of return-air room 15 is connected with muddy water mixing chamber bottom, and is provided with the second screen pack 25.The top of return-air room 15
By blowdown pipe 24 with being connected at the top of negative pressure chamber 8.Second water pump 18 takes out the mixed liquor of the bottom of return-air room 15 by return duct 19
Put to caching case 3.Flow control valve can be installed on blowdown pipe 24.
The present embodiment has two kinds of mode of operations.
Mode of operation one：Only the first water pump 17 works, and the second water pump 18 does not work.So as to the mixed liquor from casing 1
Enter inclined-plane case 5 by house steward 4 again after into caching case 3, a large amount of mixed liquors are when entering inclined-plane 6 position of small opening, and liquid level is raised
To 6 mouthfuls of positions of inclined-plane small opening, because the fluids such as solid and sludge are heavier, stop again by the first screen pack 7, will be along spoil disposal passage
11 are flowed downward, and superfluous water is excluded to the bottom of negative pressure chamber 8 from the outlet of inclined-plane case 5, are entering water purifying tank by output channel 9
10。
Mode of operation two：First water pump 17 and the second water pump 18 work simultaneously.Mixed liquor from casing 1 enters caching case
After 3 again by house steward 4 enter inclined-plane case 5, a large amount of mixed liquors enter inclined-plane 6 position of small opening when, the fluid such as solid and sludge compared with
Weight, stops by the first screen pack 7, will be flowed downward along spoil disposal passage 11 again.Muddy water positioned at the bottom of spoil disposal passage 11 is mixed
There are a large amount of solidliquid mixtures in chamber 12, because the bottom of return-air room 15 is connected with the bottom of muddy water hybrid chamber 12, in the second screen pack
Under 25 effects, big quantity of fluid enters in return-air room 15, but still there is the relatively fine suspended particulate of particle diameter and be present in return-air room 15.
Extraction is interior into circulation to case 3 is cached again by the mixed liquor in return-air room 15 for second water pump 18.In the suction of the second water pump 18
Under effect, air pressure is relatively low in return-air room 15, is conducive to mixed liquor suction constantly entering return-air room 15, when mixing flow velocity is relatively low
When, negative pressure chamber 8 is connected with return-air room 15 by carry out tonifying Qi by blowdown pipe 24.Now, appropriate negative pressure is formed in negative pressure chamber 8
Value, is conducive to accelerating liquid in inclined-plane case 5 and excludes downwards into the bottom of negative pressure chamber 8, entering water purifying tank by output channel 9
10。
It can be seen that, mode of operation two can further filter mixed liquor, the first filter screen is required during usual selection work pattern two
Aperture be less than the second filter screen aperture, so in the case where not influenceing operating efficiency can as far as possible filter out tiny suspension
Thing.
Hand-hole 23 on the upside of casing, which is used for constantly adding into casing, needs waste water to be processed, positioned at bottom half
Sewage draining exit 20 be used for periodically discharge precipitation sludge.
Embodiment 2：Referring to Fig. 1, on the basis of embodiment 1, water purifying tank 10 is located at the upside of casing 1, and in water purifying tank 10
Set between casing 1 and be provided with spoil disposal passage, spoil disposal passage blowdown control valve 22.
Embodiment 3：Referring to Fig. 1, on the basis of embodiment 1, the vacuum tank bottom is provided with inclined 3rd filtering
Net 26, and sewage draining exit is set in the downstream of the 3rd screen pack 26 and blowdown control valve is installed；The output channel 9 is located at the 3rd mistake
Immediately below filter screen 26.The aperture of first screen pack 7 is less than the aperture of the second screen pack 25, and the aperture of the 3rd screen pack 26 is less than the
The aperture of one screen pack 7.The screen pack of three groups of diverse locations can substantially carry out filtering blowdown, so that discharge of wastewater reaches
Mark, but not cause congestion, and in the case of not interfering with filtration efficiency.
