Embodiment
See accompanying drawing 1, the continuous way three phase fluidized bed that this utility model embodiment provides includes housing 12, enters fluidic distributor the 1, first outlet 2, elevator pump 4, solid-liquid memorizer the 6, second outlet 5, separator 9, promotes pump line 13, return duct the 7, the 3rd outlet the 11, the 4th outlet 10, casting bed 8, elevator pump 4, promote pump line 13, enter fluidic distributor 1, solid-liquid memorizer the 6, first outlet the 2, second outlet 5, return duct 7, casting bed 8 are respectively contained in housing 12；Elevator pump 4 is arranged at bottom lifting pump line 13, and the top promoting pump line 13 connects with solid-liquid memorizer 6, and solid-liquid memorizer 6 also one end with the second outlet 5 connects, and the other end of the second outlet 5 connects with one end of separator 9；Housing 12 is divided into upper and lower by casting bed 8；One end of return duct 7 connects with one end of separator 9, and the other end of return duct 7 connects with entering fluidic distributor 1；3rd outlet 11 connects with the other end of separator 9；4th outlet 10 connects with the other end of separator 9.
The continuous way three phase fluidized bed that this utility model embodiment provides uses countercurrent action, and the pending sewage water fluidic distributor 1 that enters bottom housing 12 flows into, and flows up through casting bed 8 and is filtered, is then flowed out by first outlet 2 at top.Ceramic grain filter containing impurity bottom housing 12 elevated pump pump to the solid-liquid memorizer 6 at top, separator 9 is flow to by the second outlet 5, different according to proportion, mud is discharged by the 4th outlet 10, supernatant is discharged by the 3rd outlet 11, and the clean ceramic grain filter separated is returned to casting bed 8 by return duct 7 and retained by casting bed.The cleaning of its purification that can make sewage and filtrate is carried out simultaneously, thus the continuous way three phase fluidized bed that this utility model provides can be carried out continuously uninterruptedly.
Wherein, promote pump line 13 and be arranged at the center of housing 12.In this case, surrounding's isotropism of this lifting pump line 13, it is possible to pending sewage is distributed in housing 12 more uniform.
Wherein, the bottom of housing 12 is tapered, consequently facilitating the ceramic grain filter containing impurity is built up bottom housing 12.
Wherein, casting bed 8 is arranged from housing 12 center to housing 12 sidewall slope.In this case, the clean ceramic grain filter separated can slide near the direction of housing 12 sidewall with the incline direction of casting bed 8, avoid the clean ceramic grain filter separated to accumulate in centre, cause the clean ceramic grain filter continued separating to collect difficulty.
Wherein, the periphery entering fluidic distributor 1 cladding with promoting pump line 13, the bottom entering fluidic distributor 1 has an accommodation space, and the size of accommodation space is incremented by the most successively.Can successfully be released in housing 12 so that enter into the treatment sewage of fluidic distributor 1 by return duct 7, be unlikely to be trapped within fluidic distributor 1.
Wherein, the 3rd outlet 11 is arranged on the top of the 4th outlet 10.Wherein, 3rd outlet 11 for the treated supernatant of drain, and the 4th outlet 10 for drain by the mud of isolated, owing to the density of supernatant is less than the density of mud, therefore, the 3rd outlet 11 is arranged on above the 4th outlet 10 can be easy to carry out drain according to density.
Wherein, casting bed 8 is in mesh-like structure, and the several size according to haydite of mesh of mesh-like structure selects.When the particle diameter of haydite is bigger, the screen cloth that mesh number is less can be selected, when the particle diameter of haydite is less, the screen cloth that mesh number is bigger can be selected, thus reduce the haydite separated and leak down to the bottom of housing 12 from casting bed 8, reduce separation efficiency.
Wherein, the first outlet 2 is arranged at the top of housing 12, so that the supernatant through natural subsidence clarification is drained from the first outlet 2.
Wherein, the connecting portion of the second outlet 5 and solid-liquid memorizer 6 is arranged at the bottom of solid-liquid memorizer 6, consequently facilitating the solidliquid mixture being stored in solid-liquid memorizer 6 enters in the second outlet 5.
Wherein, the corner of the second outlet 5 is rounded, and the corner of return duct 7 is rounded.Thus avoid solidliquid mixture to deposit in the corner of the second outlet 5, or, mud deposits in the corner of return duct 7.
Although having been described for preferred embodiment of the present utility model, but those skilled in the art once know basic creative concept, then these embodiments can be made other change and amendment.So, claims are intended to be construed to include preferred embodiment and fall into all changes and the amendment of this utility model scope.
Obviously, those skilled in the art can carry out various change and modification without deviating from spirit and scope of the present utility model to this utility model.So, if these amendments of the present utility model and modification belong within the scope of this utility model claim and equivalent technologies thereof, then this utility model is also intended to comprise these change and modification.
