Description
Technical field
the utility model relates to the storage basin in a kind of sewage treatment industry, and particularly a kind of suspended chain moves the structure that increases storage basin volume in aeration system.
Background technology
take the Cao Feidian of municipal drainage Co., Ltd district, Tangshan operation branch company is example: this factory during due to design storage basin volume less, dischargeable capacity is 5 * 5.95 * 2.15=63.96 cubic meter, and at present, this factory's sludge output every day is through measuring and calculating 10 tons of left and right, and storage basin actual needs holds 90 cubic metres of left and right of the former mud of moisture content 98%.This shows, storage basin can not meet the desliming amount of every day.The current technique of this factory is to utilize the mobile limit switch that second pond installs additional as sedimentation basin that the precipitation excess sludge of 8～10 hours is pressed to storage basin in the effect of gravity.At twice mud is entered to storage basin; During entering mud, second pond driving can not normally move for 1.5～2 hours.
Summary of the invention

adopt the utility model of technique scheme compared with prior art, can increase the storage mud volume of stablizing exteenal reflux canal; Improved storage mud rate.
preferred version of the present utility model is:
second enters on mud pipe the first gate valve and the second gate valve are housed, and second of the first gate valve and the second gate valve enters on mud pipe tubing pump is housed.
second enters mud pipe is placed in a side of the second channel gate and is communicated with stable exteenal reflux canal.
kuppe is equipped with in one end of entering mud pipe on storage basin, and the other end that enters mud pipe is communicated with exteenal reflux canal by gate.
entering mud pipe and second enters on mud pipe to be respectively installed with heat-insulation layer.
on the overflow pipe of storage basin, shutoff is housed.
Accompanying drawing explanation
fig. 1 is top view of the present utility model.
fig. 2 is that A in Fig. 1 is to enlarged drawing.
fig. 3 is the structural representation of storage basin.
The specific embodiment
below in conjunction with drawings and Examples in detail the utility model is described in detail:
a kind of suspended chain moves the structure that increases storage basin volume in aeration system, referring to accompanying drawing 1 to accompanying drawing 3, in figure: exteenal reflux canal 1, stabilization pond 2, gallery 3, stablize exteenal reflux canal 4, second pond 5, second pond exteenal reflux canal 6, aeration tank 7, enter mud pipe 8, the first channel gate 9, the second channel gate 10, second enter mud pipe 11, the first gate valve 12, heat-insulation layer 13, the second gate valve 14, tubing pump 15, gate 16, guardrail 17, gate valve 18, kuppe 19, dredge pump pipe 20, storage basin 21, clear water pump line 22, water inlet pipe 23, overflow pipe 24, former channel gate 25.
in the present embodiment, the entering of storage basin 21 is equipped with second and enters mud pipe 11, the second and enter mud pipe 11 and be connected with exteenal reflux canal 1 on mud pipe 8; The exteenal reflux canal 1 arranging respectively on exteenal reflux canal 1 between the first channel gate 9 and the second channel gate 10, the first channel gates 9 and the second channel gate 10 is communicated with second pond exteenal reflux canal 6; Exteenal reflux canal 1 is communicated with stable exteenal reflux canal 4.
utilize channel gate, it is 39.67 cubic metres that final storage basin 21 obtains increasing dischargeable capacity; The dischargeable capacity and the storage basin dischargeable capacity that increase are stored up 103.63 cubic metres, mud altogether; Meet the needs of dehydration workshop desliming completely.
second enters to be equipped with on mud pipe 11 second of the first gate valve 12 and the second gate valve 14, the first gate valves 11 and the second gate valve 14 enters tubing pump 15 is housed on mud pipe 11; Tubing pump 15 electricity consumptions are from second pond 5 driving power supplys.
second enters mud pipe 11 is placed in a side of the second channel gate 10 and is connected with stable exteenal reflux canal 4.
kuppe 19 is equipped with in one end of entering mud pipe 8 on storage basin 21, and the other end that enters mud pipe 8 is connected with exteenal reflux canal 1 by gate 16.Kuppe 19 changes mudflow and moves towards problem, prevents from impacting dredge pump pipe 20.
entering mud pipe 8 and second enters on mud pipe 11, to be respectively installed with heat-insulation layer 13.
compared with prior art, tool has the following advantages the utility model:
because former storage basin volume is less, adopt and formerly enter mud mode and enter mud, that is to say and will have the time mud of 1.5～2 hours not reflux, external reflux ratio is up to 91.6%; By the utility model technology external reflux ratio, rise to 6.3%, guarantee to greatest extent the continuity of process operation, stability.
chain reaction on process operation: storage basin volume is little--enter the length-exteenal reflux of mud time not in time-growth of microorganism environment is unstable-effluent quality impact.In exteenal reflux mud, carry a small amount of dissolved oxygen secretly under normal circumstances, if refluxed not in time, the aerobic amount in proparea increases, and to aeration tank oxygen demand, increases, and fan energy consumption increases.
the former function of stabilization pond 2 is mainly backflow stabilization pond mud, intermittent duty.By the second channel gate 10, its function is increased to storage basin function.Stabilization pond 2 sludge refluxes do not contradict with storage basin function.Former storage basin volume is little, and after being about to purify in storage basin, secondary enters mud, and secondary enters mud process dredge pump is impacted.After transformation, add kuppe 19 and can institute's mud that stores up in stabilization pond backflow canal be taken off while entering according to desliming efficiency, having solved the shock problem to dredge pump.
operation contrast before and after storage basin transformation:
before transformation: upper storage reservoir enters mud: first, stop stabilization pond 2, second pond 5 drivings by the emptying of exteenal reflux canal ponding.Second step, gets back in system and goes former channel gate 25 to close in order to prevent from resting on excess sludge in second pond 5.The 3rd step, will enter after mud gate 16 is opened and flow to mud by gravity.The 4th step, upper storage reservoir enters mud: when storage basin excess sludge is down to 30 cubic metres, secondary enters mud.The 5th step, enters mud and completes, and it is normal that driving, gate etc. recover.
after transformation: upper storage reservoir enters mud: first, stop stabilization pond 2, second pond 5 drivings by the emptying of exteenal reflux canal ponding.The first step, closes the first channel gate 9; Excess sludge is suppressed to the highest the second channel gate 10 and closed, and opening former gate 16, to enter mud full to storage basin 21.The 3rd step, takes out the first channel gate 9, closes former gate 16, second pond 5 driving operations.The 4th step, opens the first gate valve 12, tubing pump 15.The 5th step, takes out the second channel gate 10, closes the first gate valve 12, tubing pump 15 etc. and recovers normal.
by the increase of storage basin volume, optimize the operational procedure that worker enters mud, from original twice upper storage reservoir, entered mud, become a upper storage reservoir and enter mud, improved whole operating efficiency.
