Abstract
The invention discloses a sludge dewatering equipment. According to the sludge dewatering equipment, the sewage and sludge can be effectively dewatered, and the energy consumption is reduced. The sludge dewatering equipment mainly comprises the following parts: a shell, a motor, a filtrate recycling tank, a rotating shaft with spiral blades, a dewatering cavity with a hole and a mud guard plate. According to the sludge dewatering equipment disclosed by the invention, high dewatering efficiency is realized, the energy consumption is reduced, the pollution can be reduced, and the energy is saved.
Description
Technical field
The present invention relates to Non-aqueous processing field, relate to sludge dewatering equipment particularly.
Background technology
In the industrial production of fermentation arts, sewage disposal is one of main environmental issue.Generally, by Industrial Wastewater Treatment station, but wastewater treatment standing-meeting produces mud, and institute to produce general inorganic mud in mud more, containing the chemical composition in factory effluent, belong to class of giving up of endangering, still need further process.The most basic handling of industrial sludge is dewatered exactly.
There will be a known multiple method to process mud, existing sludge dewatering equipment mainly contains following several:
1, plate and frame sludge dewatering equipment: under airtight state, 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.
2, belt mud dewatering equipment: 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, the tension force of strainer itself is relied on to form squeezing to sludge blanket and shearing force, capillary water in sludge blanket is squeezed out, thus realizes sludge dewatering.
3, Centrifugal sludge dehydration machine: by reprint and auger conveyor with hollow rotating shaft forms, mud sends into rotating cylinder by hollow rotating shaft, under the centrifugal force that High Rotation Speed produces, produces and is namely dumped in rotary drum chamber.Because proportion is different, form Separation of Solid and Liquid.Mud, under the promotion of auger conveyor, is transported to the cone end of rotary drum by exporting continuous discharge; The liquid of pendular ring layer then drains into rotary drum by crest of weir continuous " overflow " and discharges by gravity outward.
But prior art still has a lot of shortcoming:
1 easily blocks.In Separation of Solid and Liquid process, no matter be belt and centrifugal dewaterer, the dewaterer of plate and frame, all also exists and holds susceptible to plugging phenomenon.In order to prevent blocking, above-mentioned various type all can only rinse with a large amount of water, and this not only causes water waste, and a large amount of flushing waters adds the burden of sewage disposal Inner eycle.And once blocking, just necessary maintenance down, causes dewaterer not run continuously, have impact on the normal production running of enterprise or society.Spiral sludge dewatering machine adopts the design principle of multiple laminated spiral press filtration, promotes travelling ring and rotates, thus constantly clear up the dirt in gap, thoroughly prevent blocking by the rotation of helical axis.
2 operating costs are too high.During the sludge dewatering equipment of conventional types, operating cost is too high really.Except huge charges for water and electricity, somebody's expenses of labour such as to administer and maintain at the expense.And spiral sludge dewatering machine tick-over runs, very micro-to the consumption of electric energy, consumption per hour is also no more than 2 degree.Further, achieve continuously unmanned operation, economized many labour costs.
3. low concentration sludge dewatering could be dewatered after having to pass through and concentrating, and this just requires to build to concentrate and concentrates low concentration mud with storage pool.Treatment cycle and floor space larger.
Summary of the invention
The invention discloses 1, a kind of sludge dewatering equipment, it comprises: (1) filtrate accumulator tank, (2) shell, (3) are with the rotating shaft of helical blade, (4) dewatering cavity, (5) feed pipe, (6) helical blade, (7) mud discharging mouth, (8) baffle plate and (9) motor; Wherein said rotating shaft runs through dewatering cavity, one end is connected with motor, the other end is connected with baffle plate through the mud discharging mouth on housing, helical blade is continuous print, along rotating shaft from motor side to mud discharging mouth end spiral, and the radius of blade and between spacing constantly reduce along ascent direction, the distance of blade and dewatering cavity wall is no more than 0.5cm; Porose on the wall of dewatering cavity.
In some embodiments, sludge dewatering equipment of the present invention also has reservoir, and the vertical range of its distance rotating shaft (3) is more than or equal to 10 meters.
In some embodiments, in sludge dewatering equipment of the present invention, the diameter of dewatering cavity diminishes gradually along inlet end to the direction of mud discharging mouth.
In some embodiments, in sludge dewatering equipment of the present invention, the size in the hole on dewatering cavity wall is different, diminishes gradually along entering the direction of mouth of a river end to mud discharging mouth.
The endless spiral of sludge dewatering equipment of the present invention and dewatering cavity define the cavity that a sectional area constantly diminishes, add that the hole on dewatering cavity wall constantly reduces, make constantly increasing from inlet port end to mud mouth end to fluid applied pressure wherein, achieve more high efficiency dehydration, dehydration rate can reach more than 90%.
Sludge dewatering equipment of the present invention can also have very high reservoir, utilizes gravity as the part gravity of charging and dehydration, reduce further the consumption to the energy, compared with the sludge dewatering equipment of other types, can reduce the total electricity consumption of about 30%.
Sludge dewatering equipment of the present invention without concentrated with regard to Direct Dehydration, can both eliminate the cost building concentrated and storage pool, the more important thing is and realizing Direct Dehydration, can reduce the release of phosphorus and the generation of foul smell the mud of more than concentration 2000mg/L.

Detailed description of the invention
Fig. 1 is a specific embodiments of sludge dewatering equipment of the present invention.It comprises (1) filtrate accumulator tank, (2) shell, (3) are with the rotating shaft of helical blade, (4) dewatering cavity, (5) feed pipe, (6) helical blade, (7) mud discharging mouth, (8) baffle plate and (9); Wherein said rotating shaft (3) runs through dewatering cavity (4), one end of rotating shaft (3) is connected with motor, the other end is connected with baffle plate (8) through the mud discharging mouth (7) on housing, helical blade (6) on rotating shaft (3) is continuous print, helical blade (6) is along rotating shaft from motor side to mud discharging mouth end spiral, and the radius of helical blade (6) and between spacing constantly reduce along ascent direction, the distance of helical blade (6) and dewatering cavity (4) wall was no more than 0.5cm; Porose on the wall of dewatering cavity.The sludge dewatering equipment of the present embodiment also has reservoir (10), and the vertical range of reservoir (10) distance rotating shaft (3) is more than or equal to 10 meters; Wherein the diameter of dewatering cavity (4) diminishes gradually along inlet end to the direction of mud discharging mouth.And the number of the osculum on it reduces gradually.
Because the discontinuity that waste water is got rid of, so waste water is accumulated in higher position to have laid in larger potential energy, by feed pipe to entering into dewatering cavity.Rotate because potential energy promotes rotating shaft, decrease the needs of the power to motor.
