Description
Technical field
The present invention relates to a kind of sludge treatment device, be particularly obliquely installed the sludge dehydration device that automaticity is high。
Background technology
Along with country is further strict to the requirement of environmental protection, oily sludge is innoxious, minimizing, resource treatment technique are just becoming the trend of sludge disposal technology development。
But, petrochemical industry oily sludge is of a great variety, character is complicated, original oily sludge processed mode: plate and frame type filter-press, roller belt dewaterer, centrifugal drier, it is suitable in process in reality and is confirmed, the processed of oily sludge cannot be suitable for, not only waste substantial amounts of fund, and create secondary pollution, also make the economic benefit of petrochemical industry sustain a loss。The processed of oily sludge has become as a big technical barrier of puzzlement petrochemical industry。
At present, the sludge dewatering of China's water treatment field mainly adopts the dehydrations such as Horizontal helical type centrifuge, belt filter press, filter press。In actual motion operates with, particularly in processing oily sludge process, many problems are encountered, it is difficult to solve, be not very good。
1, Horizontal helical type centrifuge:
After Horizontal helical type centrifuge sludge dewatering, moisture content is about 80%, and machine body parts are less。Under the centrifugal action that high speed rotating produces, mud granule is dumped on drum inner wall, slowly promotes at spiral and discharges down to the outlet of tapered end place, and liquid is discharged by opposite direction。This machine disadvantage: power consumption is big, not energy-conservation, use cost is high, and noise is also big。From noise angle, it is again a polluter。Easily breaking down because running up, spare and accessory parts life cycle is short, and maintenance difficulty is big, cannot keep in repair without dynamic balancing equipment, once deviation occurs in spindle balance, device damage is bigger, manufacturer can only be asked to keep in repair, add working service cost。
2, belt filter press:
Belt filter press is dehydration equipment conventional at present。It is that pressure is applied on filter cloth, utilizes the tension force of the pressure of filter cloth to make sludge dewatering。But filter cloth easily blocks, viscous oil, sideslip, in order to prevent blocking, can only being rinsed with substantial amounts of water, substantial amounts of flushing water adds the burden of sewage disposal internal recycle, causes secondary pollution。In order to prevent filter cloth sideslip, adding anti-deviation device, structure is complicated, is easily generated fault。Filter cloth also needs periodic replacement, and operating cost is higher, and workshop is poor。
3, filter press:
The filter press pressure by liquid feeding pump, makes sludge water pass through filter cloth and discharges, and fine particle is trapped in frame intracavity。After frame intracavity mud is had one's bosom filled with, stop charging, mobile filter plate, make mud fall down discharge。Its advantage: low price, mud pump characteristic are high；Its weak point: can not continuous operation, during artificial mobile filter plate, labor intensity is big, and as adopted automatic pulling plate, automatically cleaning filter cloth device, structure is complicated, and glitch frequency is many。The mud that viscosity is high cannot normally dehydration。Filter cloth must often clean, change, and changes filter cloth at least several thousand yuan and poor working environment。
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of simple in construction, easy maintenance, it is possible to after making sludge dewatering, moisture content is 80～85%, it is prevented that the sludge dehydration device of secondary pollution。
For realizing the object of the invention, provide techniques below scheme: a kind of sludge dehydration device, including the underframe that installed surface is inclination 10 degree ~ 20 degree, it is mounted on the conveyer device on underframe installed surface, it is characterized in that conveyer device includes U-shaped delivery chute, cover in the seal closure on U-shaped delivery chute, it is arranged at the screw conveyor shaft in U-shaped delivery chute, T-shaped adapter sleeve upper end is stretched out U-shaped delivery chute and is connected actuating device, lower end is inserted in bearing block, screw conveyor shaft upper end is arranged with T-shaped adapter sleeve, T-shaped adapter sleeve is provided with at least 3 leads around the center of circle, lead is arranged with holddown spring, it is arranged with clamping sleeve above T-shaped adapter sleeve, T-shaped adapter sleeve and clamping sleeve periphery are provided with sealing shroud, it is provided with sludge water import on the upside of U-shaped delivery chute lower end, bottom side, U-shaped delivery chute nearly upper end is provided with mud discharging mouth, underframe is hollow seal housing, installed surface offers permeable hole, underframe sidewall is provided with osculum。
As preferably, screw conveyor shaft includes conical section and isometrical section。
As preferably, the pitch of the helical blade on conical section is 2.5 times of the pitch of the helical blade of isometrical section。
As preferably, being provided with shower in seal closure, seal closure top is provided with air vent。
As preferably, the installed surface of screw conveyor shaft, shower and underframe be arranged in parallel。
When equipment runs, mud enters from sludge water import, drive the coaxial helical axis with concentration and dehydration assembled by actuating device and make move in the multiple fixing lamination filtering bodies of composition of multiple travelling lamination carry out dehydration, from the wastewater inlet of enriching section to the cake outlet of dewatering period, the pitch of helical axis tapers into, and the gap between retainer ring and travelling ring also tapers into。Mud is up transmitted and is squeezed out by the moisture in mud by pitch from large to small, and dewatered sludge is discharged by mud mouth, and the moisture squeezed out is collected by the drip tray tilted and discharged。Sludge outlet place is provided with spring attachment, with the pressure of adjustable screw intracavity。When dewaterer run a period of time lamination need to clean time, shower electromagnetic valve can be opened and spray, to lamination and helical axis, the purpose that clear water reaches automatically to clean by shower。
A large amount of harmful substance is carried for oily sludge, oil content compared with high, viscosity is big, granule is thin, be difficult to the features such as dehydration, the sludge dewatering equipment that our company produces is as nucleus equipment, technological process before coordinating, mud is through processed aftershaping, after general oily sludge dehydration, moisture content is 80～85%, not only overcome belt type dewaterer, plate and frame type filter-press easily blocks, centrifuge is difficult to the shortcomings such as separation, and achieve the recovery of greasy filth, farthest meet that oily sludge is innoxious, minimizing, recycling treatment requirement。
The method have the benefit that reduction Treatment of Sludge is taken up an area: can directly process mud or second pond mud in Aeration tank, not need to arrange sludge concentration tank and storage pool, save and take up an area。Lifting system phosphorus removal functional: mud dehydration under aerobic condition, it is to avoid the mud Phosphurus release under anoxia or anaerobic condition, promotes the dephosphorization function of system。Operational management is simple: no filter-fabric, filter opening etc. be obturating element easily, runs safe and simple, in conjunction with full-automatic medicine system, it may be achieved unattended operation in 24 hours。
Reduction system processes load: sewage sludge is close-coupled processing, alleviates subsequent biochemical reactor。Automaticity is high, alleviates staff labor intensity。
