Description
Technical field
The utility model relates to technical field of sludge treatment, is specifically related to convection cell shape mud and is rotated pressurization, reaches a kind of dehydration equipment of dehydration object.
Background technology
Along with the attention of country to environmental protection, sludge treatment also obtains development, and a vital task of sludge treatment reduces sludge volume exactly, reduces the water ratio of mud.According to the regulation of GB18918-2002 < < urban wastewater treatment firm pollutant emission standard > >, the water ratio of mud should be less than 80%.It is widely used means both at home and abroad that the mode of utilizing at present mechanical dehydration carries out to mud that thickening processes, and is also a kind of method feasible and that efficiency is very high.Common mechanical dehydration method has filter press dehydration, belt type filter-pressing dehydration plant, centrifuge dehydration and folded spiral shell extrusion dehydration, the off-line equipment of these several modes respectively has relative merits, as high in centrifuge power consumption, noise is large, filter press water extracter can not continuity move, operate inconvenience, belt type filter-pressing dehydration plant volume is large, maintenance cost is high, and folded spiral shell extruding-desiccation machine treatment capacity is little etc.The advantages such as occurred in recent years a kind of rotating-expressing type water extracter, its principle of work is that rotary squeezing medium dewaters, and this equipment can meet operation continuously, simple to operate, volume is little, power consumption is low, maintenance cost is low.
Rotating-expressing type water extracter is developed so far through updating, and some types are applied in project, but equipment still there are the following problems:
1, the filter press plate of rotating-expressing type water extracter is generally a certain specification, when treatment capacity is larger, be all to improve processing power by increasing filter press plate or runner number, as the Multicenter rotating extrusion type filter of the parallel multiple-pass rotary extrusion type filter of patent CN201159575 and CN201108780Y, when filter press plate is more, cantilever increases, need the moment of torsion that rotating shaft provides can be very large, drive shaft be easily out of shape because bearing compared with large load.Filter press plate increases, and its floor space increases simultaneously, and power consumption is also multiplied.
2, the runner of existing rotating-expressing type water extracter is comprised of outer ring spacer, two side screens, cone spacer and mud extraction dividing plate; cone spacer and two side screens are rotatable parts; outer ring spacer and mud extraction dividing plate are mounting block; restriction due to structure; mud extraction dividing plate location and fixing more difficult; in mud extraction dividing plate when assembling, is difficult to form reasonable coordination with cone spacer, often there will be inside mud extraction baffle plate plucking and run mud phenomenon in actual motion.When the pressure of water extracter is larger simultaneously, can cause the distortion of mud extraction dividing plate, damage equipment; Pressure is turned down, at the bottom of mud cake output, of poor benefits.The cross section of existing runner is rectangle, and runner middle portion mud is not easy effective dehydration, and runner is imported and exported flow blind angle, and mud flows not smooth.
3, in rotating-expressing type water extracter, filter screen is the core component of equipment, and the quality of filter screen directly has influence on the dewatering of equipment, and filter screen needs high, the easy cleaning and regeneration of filtering accuracy, long service life.Existing filter screen has metal sheet filter screen, multistorey strainer mesh, combination filtering net.The metal sheet filter screen that patent CN1378478, CN1524008 and CN2644426 describe, this metal sheet is generally punching press, galvanic corrosion or electroforming and forms, and the thickness of orifice plate is limited, and work-ing life is shorter; The multistorey strainer mesh that patent CN2571751 describes, if the wearing and tearing of interior filter plate, filter screen had also just lost efficacy, work-ing life is shorter equally; The combination filtering net that patent CN2907832 describes, this filter screen is by filtering bar and support bar combines, when rinsing, can affect cleaning performance because of stopping of support bar, because filter bar is linear, the filter opening forming is also vertical bar, when filter screen rotates, the flushing angle of vertical bar hole and flushing port can not keep best corresponding states always, and developing result is unsatisfactory.
4, existing water extracter is only provided with flushing arrangement on mud extraction dividing plate, the filter screen proceeding to before opening for feed is cleaned, and often there is filter net jam phenomenon in the compression of mud, dehydration, in this process, filter screen is not cleaned, filter screen not in time cleaning can have a strong impact on follow-up press filtration effect, while finally causing discharging, water ratio is higher, can not meet requirement of engineering.
Summary of the invention
The utility model provides double plate rotating-expressing type water extracter, the utility model has solved existing sludge treatment device, the problem that unreasonable structure causes after treatment capacity increases, change flow passage structure simultaneously, improve stability and the reliability of its component, increase flushing arrangement, strengthen cleaning, the refresh function of filter screen.
For addressing the above problem, the utility model adopts following technical scheme: double plate rotating-expressing type water extracter, comprise left filter press plate 1, main shaft 2, support 3, motor and speed reducer 4 and right filter press plate 5, motor and speed reducer 4 is installed on above support 3, on the main shaft of motor and speed reducer 4 left and right outputs, left filter press plate 1 and right filter press plate 5 is installed; Described left filter press plate 1 is identical with right filter press plate 5 structures and be symmetrical set; Left filter press plate 1 and right filter press plate 5 comprise respectively the supporting disk 14 that is arranged at mid-way and the end cap 12 that is installed on supporting disk 14 left and right sides; It between two supporting disks, is runner 8, runner 8 is integral structures, comprise and be positioned at the circular outer ring spacer 17 in outside, cone spacer 21 and the mud extraction dividing plate 19 of inner side, in cone spacer 21, have the axis hole that main shaft is used is installed, between cone spacer 21 and outer ring spacer 17, be connected with mud extraction dividing plate 19, mud extraction dividing plate 19 both sides are provided with opening for feed 18 and the discharge gate 20 that connects cone spacer 21; Supporting disk 14 left and right sides are fixedly connected with respectively net-filter assembly 10, and net-filter assembly 10 covers the annular region of supporting disk 14 both sides.
The utility model provides a kind of double plate rotating-expressing type water extracter, in equipment, only have two filter press plates, by increasing filter press plate diameter and thickness, expand treatment capacity, therefore the main shaft cantilever of equipment is short, stress condition is better than existing Multicenter rotating extrusion type filter, equipment does not need independent bearing and strut member thereof, compact construction.The contrast of double plate rotating-expressing type water extracter and Multicenter rotating extrusion type filter, volume is less, and energy consumption can reduce by 20% ~ 50%, and structural advantage is obvious.
