Description
Technical field
The utility model relates to a kind of waste disposal plant of environment protection, particularly a kind of novel scraping and sucking machine.
Background technology
In the existing municipal sewage treatment, adopt the settling tank sludge settling more, with suction dredger or mud scraper mud is all siphoned away or blows off again.Owing to have active sludge and inertia mud in the mud, the settling velocity of active sludge is slower, be deposited in the radiation zone outside the radial-flow sedimentation tank center 1/3rd more, and inertia sludge settling speed is fast, be deposited in the central zone of settling tank more, but existing installation just carries out processed with above-mentioned blended mud simply, and preferably above-mentioned mud is not separated, thereby influence the second stage employ effect of active sludge, and the settling velocity of mud is variant, prolong the time that mud forms, caused the increase of engineering time.
Summary of the invention
The purpose of this utility model provides a kind ofly can be rapidly carry out effectively isolating a kind of novel scraping and sucking machine with inert mud and active sludge.
The outside that the utility model is included in the settling tank of funnel type is connected to mud-collecting well of active sludge, mud-collecting well of inert sludge by shore pipe respectively, settling tank is provided with a resting support that rotates around the center support of hollow, and there are mud-sucking device and Scraping device in this resting support lower end independent suspension respectively; The top that resting support is positioned at central shaft is provided with guide shell, and mud-collecting slot is located at the guide shell inner upper end;
Above-mentioned described mud-sucking device comprises that a side stationary distribution of resting support has a plurality of and sludge pipe to join and extends near the suction mud of settling tank bottom and chews, sludge pipe is connected with mud-collecting slot, shore pipe one end is communicated with mud-collecting slot, and the other end is connected with the mud-collecting well of active sludge;
Described Scraping device comprises that the opposite side of resting support is hung with many hoist cables, the hoist cable end is connected with the cleaning shoe that is arranged at the settling tank bottom, settling tank bottom centre zone is a spill mud, and shore pipe one end and bucket join, and the other end is connected with the mud-collecting well of inert mud.
Active sludge shore pipe described in the utility model is positioned on the settling tank axis, and inserts and extend to mud-collecting slot from the bottom of settling tank and join; Water inlet pipe is overlapped on the skin of shore pipe, and is connected with guide shell;
The guide shell bottom is connected with settling tank, flows to water to settling tank from the water inlet pipe spoke, and water shoot is positioned at the outermost layer of settling tank.
Adopt technique scheme, owing to be hung with and inhale the resting support that mud chews with cleaning shoe and constantly rotate around center support, make and inhale mud and chew the active sludge that will be deposited in preferably at the bottom of the pond and suck in the mud-collecting slot, under the hydrostaticpressure effect in shore pipe enters mud-collecting well of active sludge, and cleaning shoe is under resting support drives, the inertia mud that constantly will progressively be deposited on the pool center zone blows off, enters in the inertia mud mud-collecting well by shore pipe under the hydrostaticpressure effect; The utility model can separate active sludge effectively with inertia mud, improve the biochemical reactant total amount greatly, make mud that higher activity be arranged, the SVI value is in reasonable range in the maintenance aeration tank, improved the settling property of active sludge, strengthened the ability and the processing power of anti-shock loading, thereby also reduced the residence time of mud, reduced the construction investment cost at settling tank.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is a cross-sectional view of the present utility model;
Fig. 2 is the structural representation that the utility model is overlooked direction.
Embodiment
As Fig. 1, shown in Figure 2, the utility model is made up of the settling tank 14 of a cylinder funnel type and the mud-collecting well of active sludge 1 and the inertia mud mud-collecting well 13 that are distributed in settling tank 14 both sides, be fixed with a resting support 15 around the axis rotation on the center support of the hollow of settling tank 14, resting support 15 1 side stationary distribution have a plurality of and sludge pipe 4 to join and extend near the suction mud of settling tank 14 bottoms chews 3, the mud that is deposited at the bottom of the pond can be chewed 3 and sucks and be delivered in the mud-collecting slot 9 that is in central axis by sludge pipe 4 by inhaling mud, is entered in the mud-collecting well of active sludge 1 by the static pressure of shore pipe 7 by water again; The opposite side of resting support 15 is hung with many hoist cables 10, the end of hoist cable 10 is connected with the cleaning shoe 8 that is arranged at settling tank 14 bottoms, the inertia mud that cleaning shoe 8 constantly will comparatively fast be deposited at the bottom of the pond is concentrated the central zone of scraping to settling tank 14 bottoms, because central area is provided with the bucket 5 of spill, inertia mud is from the static pressure of bucket 5 by water, in shore pipe 11 enters inertia mud mud-collecting well 13; Water inlet pipe 2 is connected with the hollow space of settling tank 14 center supports, flows to into settling tank 14 precipitations by guide shell 6 spokes; The edge of settling tank 14 also is provided with water shoot 12.
During use, municipal effluent flows into guide shell 6 by water inlet pipe 2, flow into settling tank 14 by guide shell 6 again, inertia mud and active sludge in the settling tank sewage begins sedimentation regularly simultaneously, at this moment, connect power supply, make resting support 15 actions, resting support 15 drive inhale mud chew 3 and cleaning shoe 8 rotate around the central shaft of settling tank 14, suction mud chews 3 will precipitate slower active sludge suction, deliver to mud-collecting slot 9 along suction pipe 4, enter in the mud-collecting well of active sludge 1 by shore pipe 7 again, thereby finish suction mud, the spoil disposal process of active sludge; Meanwhile, under the rotatablely moving of resting support 15, cleaning shoe 8 will precipitate faster, and inertia mud scrapes, progressively the sludge hopper 5 of central zone is concentrated at the bottom of the pond, in shore pipe 11 enters inertia mud mud-collecting well 13, thereby finish the process of the dirty scraping mud of inertia, collection mud, spoil disposal, water shoot 12 effluxes the water of post precipitation.
