Description
Technical field
The utility model relates to environmental purification field, is specifically related to a kind of centrifugal sludge treatment device.
Background technology
Mud is the inevitable outcome after sewage treatment plant and sewage plant sewage disposal, after the mud entered environment that process is disposed very well, will bring secondary pollution, also will constitute serious threat to the activity of ecological environment and the mankind directly to water body and air.Therefore, mud is very prudent in process, and mud can be divided into dewatering technology of mud and sludge drying process two kinds in process.
The mud of sewage treatment plant roughly has: materialized mud, biochemical sludge, Physiochemical and biochemical mixing sludge etc. three kinds.
For different processing environments, the normal equipment adopted has centrifugal: three kinds of mud all can adapt to, but high, the high rotating speed that consumes energy causes noise large.Strainer formula: adapt to materialized mud, and filter cake moisture content is low, to the bad adaptability of mixing sludge and biochemical sludge, returned sludge is many, and backwash water amount is large, energy consumption is high, and maintenance is complicated.Folded spiral shell formula: the first generation dewaterer being representative with Japanese model machine is domestic to have applied 3-4, and shortcoming is that output is on the low side.
Folded spiral shell formula sludge filter press is mutually stacked by retainer ring, travelling ring, and helical axis runs through and wherein forms filtration body.In progradation, be subject to pressure effect in the formation of back pressure plate by gravity concentration and mud and realize fully dehydration, the filter seam discharge that filtrate is formed from retainer ring and loose collar, mud cake is discharged from the end of de-watering section; Its advantage oneself to be cleaned, and do not block, low concentration mud Direct Dehydration, rotating speed is slow, power saving, and noiselessness and vibration, can realize Automatic Control, and within 24 hours, nobody runs; Shortcoming is the dehydration being bad at inorganic mud (as metal species mud), and treating capacity is less.
Belt type sludge processor, be entrained with sludge blanket by the strainer of upper and lower two tensionings, S-shaped process from the roll-in cylinder of a succession of regular arrangement, rely on the tension force of strainer itself to form squeezing to sludge blanket and shearing force, capillary water in sludge blanket is squeezed out, thus realizes sludge dewatering.Its advantage is that price is lower, uses general, technology relative maturity; Shortcoming is easy blocking, needs a large amount of rinse water, is unsuitable for the dehydration of oiliness mud, takes pity on and automatically run difficulty, maintenance management difficulty.
Centrifugal sludge treater, by reprint and auger conveyor with hollow rotating shaft forms, mud sends into rotating cylinder by hollow rotating shaft, telling under the centrifugal force rotating and produce, being dumped into immediately and turning in hub chamber.Because proportion is different, form Separation of Solid and Liquid.Mud, under the promotion of auger conveyor, is sent to the cone end of reprinting, discharges through reprinting outlet, and filtrate is then drained into by weir four overflow and reprints outer discharge.Its advantage is applied widely, and disposal ability is large, and shortcoming is that power consumption is large, and noise is large, and vibration is violent, and maintenance management difficulty, is unsuitable for the Separation of Solid and Liquid that proportion is close.
Plate and frame sludge treater is in the closed condition, and the mud squeezed into through high-pressure pump, through the extruding of sheet frame, is made the water in mud be discharged by filter cloth, reaches dehydration object.Its advantage is cheap, and be good at the dehydration of inorganic mud, moisture content of the cake is low, and shortcoming is easy obstruction, needs to use high-pressure pump, is not suitable for the dehydration of oiliness mud, is difficult to realize automatically running continuously.
In the collection and disposal process of municipal sewage, a large amount of mud will inevitably be produced, on the one hand in mud containing a large amount of organic matters and nutrient, have agricultural reutilization to be worth, can also brickmaking, make biochemical fiberboard, potting grain etc.On the other hand also may containing a large amount of heavy metal substances, pathogen, methamphetamine microorganism and a large amount of toxic organic compounds in mud, if do not dealt carefully with and disposing, will stacking and the serious secondary pollution of discharge region surrounding environment be caused.Therefore, need to provide a kind of new technical scheme to solve above-mentioned technical problem.
Application number 201120166303.2, sludge treater, comprise Treatment of Sludge engine housing and motor, sludge treater case top side has sludge inlet, sludge treater housing bottom both sides have liquid gas inlet, gas branch plate is provided with in Treatment of Sludge engine housing, gas branch plate is evenly provided with multiple breather pipe, heat exchanger is provided with in housing above gas branch plate, multiple drying machine is provided with in housing above heat exchanger, suction hood is provided with above drying machine, sludge treater housing sidewall is provided with annular overflow trough, annular overflow trough is consistent with in drying machine horizontal direction, mummification particle outlet is provided with above annular overflow trough, sludge treater case top opposite side has recyclegas outlet, recyclegas outlet is connected with drier, drier is connected with suction powder blower fan.Transfer heat to mud by heat exchanger, and make it mummification.
This patent is by the mode lignin-sludge of heating, and speed is slow, expends the energy very high.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the problem, and spy provides a kind of centrifugal sludge treatment device.
The technical scheme that the utility model adopts is:
A kind of centrifugal sludge treatment device, upper cover, turning barrel, lower cover, outer barrel, wherein the bucket face of turning barrel is provided with some evenly intensive permeable holes, turning barrel inner surface is coated with one deck filter cloth, turning barrel is connected to motor by transmission device, and outer barrel is arranged at the outside of turning barrel, and is provided with drainage channel.
During use, open upper cover, pour into mud, then close, driven by motor turning barrel High Rotation Speed, the liquid in mud is thrown to outer barrel by filter cloth and after collection, flowed out by the drainage channel of outer barrel, mud cake is cleared up by turning barrel bottom.
Described turning barrel is connected to the tumbler at center by bracing means.Stability during further increase turning barrel work.
Described filter cloth is fixed on cylinder shape framework, and filter cloth is arranged in turning barrel by cylinder shape framework.Convenient during replacing filter cloth, can the direct suction of cylinder shape framework or dial-out be passed through.
Radially be provided with some slide bars in described turning barrel, each slide bar be movably installed with cylinder compressing tablet.When rotation told by rotating cylinder, cylinder compressing tablet outwards moves along slide bar under the influence of centrifugal force and extrudes mud, increases the dehydration rate of mud further.
