Fold 161 is shunk recover after the top of elasticity closure 16 shrink tapered and close upper port, elasticity envelope when fold 161 stretches
Stifled 16 upper end forms opening.When the gas produced in sludge concentration device body 1 is more, in sludge concentration device body 1
Pressure it is larger, gas forces fold 161 to stretch, elasticity closure 16 upper end formed opening, elasticity closure upper end opening at can
Gas collecting tube is connected according to set is actually needed, collects and handles foul smell, after exhaust in sludge concentration device body 1, sludge condensation
Pressure reduces in device body 1, and fold 161, which is shunk, to be recovered, and the top of elasticity closure 16 shrinks tapered and closes upper port.
The first pond 2 is arranged below in the outlet pipe of sludge concentration device body 1, and the first pond 2 is connected with the second pond 3
It is logical, strainer is equipped between the first pond 2 and the second pond 3；The bottom in the second pond 3 by pipeline successively with water pump 4 and head cover 8
Water inlet be connected.The middle part in the first pond 2 is equipped with the step-like tiltedly filter plate 21 of slope aspect sludge concentration device body 1, i.e.,：It is close
Oblique filter plate 21 at second pond 3 is high, and the oblique filter plate 21 at sludge concentration device body 1 is low, and the first pond 2 is corresponding to oblique
Sludge outlet at the low step of filter plate 21 with mud enrichment facility body 1 is equipped with the first valve by pipeline connection, the pipeline
18, the interior sludge collected of low stepped recesses of oblique filter plate 21 is exported by pipeline.
Operation principle：Sewage enters in enrichment facility body 1 from sludge import 13, according to being actually needed to sludge import
Flocculant and nutritive salt are added in 13（Can be according to being actually needed selection addition or not add, can in batches can also be at the same time
Add）, motor 12 is opened, agitating paddle 11 starts to stir, and after a period of time, stops motor 12, stands a period of time, at this time solid-liquid
It is initially separated, upper strata is clear liquid, and clear liquid is flow in the first pond 2 from hose 5 via pipeline, the oblique filter plate in the first pond 2
21 is step-like, and the solid particle of filtering can be flow in the groove of low step along the inclined-plane of oblique filter plate 21, staff according to
The first valve 18 is opened in the amount selection of sludge, is exported, passes through strainer stream below the first pond 2 for the water after filtering, water
To the second pond 3.
When gas pressure caused by sludge fermentation in enrichment facility body 1 is larger, fold 161 is forced to stretch, elasticity
The upper end of closure 16 forms opening, and foul smell export, at this time, gas pressure declines in enrichment facility body 1, and fold 161 shrinks extensive
The top of elasticity closure 16 shrinks tapered and closes upper port after multiple.After sludge settling is complete, after supernatant liquid export,
The 3rd valve 17 is opened, thickened sludge is discharged from sludge outlet.
Need to clear up it after enrichment facility body 1 is using a period of time, opening water pump 4, in the second pond 3
Water is pumped into the hollow cavity of head cover 8, and spray is fallen out of nozzle 81, and cleaning showers are carried out to enrichment facility body 1.
