Description
Technical field
The invention belongs to sewage disposal apparatus technical field, be specifically related to a kind of without the stacked equipment for separating liquid from solid of wearing and tearing.
Background technology
At present, in the improvement and processing of sewage, the Selection and Design of sewage dewaterer is extremely crucial.Traditional sewage dewaterer comprises plate and frame type filter-press, band filter, centrifugal filters etc., are exactly that its filter cloth, strainer easily occur to stop up or damage but these dewaterers have an obvious deficiency, or energy consumption cost is compared with high and affected waste water control final effect.
For improving sewage sludge treatment effect, many enterprises and technical staff thereof have carried out a large amount of improvement research to sewage dewater unit, develop a kind of folded spiral shell formula sludge dewatering equipment, design concept is a group or several groups of filter elements that are made up of spiral impeller-hub, multiple stator and multiple moving plate, each group filter element all divides enriching section and dewatering period two parts, export to the mud cake of dewatering period from the sewage import of enriching section, the pitch of helical axis diminishes gradually, and the gap between stator and moving plate also diminishes gradually.Sludge outlet place is provided with back pressure plate, with the pressure in adjustable screw chamber.This folded spiral shell formula sludge dewatering equipment is operated in the concentrated and press dewatering of mud in one and completes: in the time that helical axis rotates, the multiple moving plate that promotion is located at helical axis periphery relatively moves, under Action of Gravity Field, water leaches from the moving plate that relatively moves and stator gap, realizes concentrated fast; Pass through concentrated mud along with the rotation of helical axis is constantly moved forward; Along mud cake Way out, the pitch of helical axis diminishes gradually, gap between moving plate and stator also diminishes gradually, the volume of helical cavity constantly shrinks, and under the effect of exit back pressure plate, interior pressure strengthens gradually, under helical axis successively continuous operation promotes, the discharge that is squeezed of moisture in mud, filter cake solid content constantly raises, and finally realizes the continuous dehydration of mud; The rotation of helical axis, promoting moving plate constantly rotates, equipment relies on the movement between stator and moving plate to realize continuous cleaning process, thereby has avoided the ubiquitous blockage problem of conventional dehydration machine, has replaced traditional filter cloth and centrifugal filter type with the delicate filter bulk-mode of uniqueness.
Part unit and inventor also with regard to fold spiral shell dewaterer the application of relevant research and development achievement patent.More representational patent application technology had: Zhejiang Dean New Technology Development Co., Ltd has proposed the application for a patent for invention (number of patent application is 200810162472.1) of " helix extrusion type sludge dehydrator " by name on November 14th, 2008, its technical scheme comprises support, water entering section, mud extraction portion, outlet part, helical axis and being arranged and the filter disc group that forms by the quiet filter disc of multiple annulars and annular dynamic filter transpostion interval, wherein, each quiet filter disc relatively support is fixed, each dynamic filter can be followed helical axis by the drive of a transmission mechanism and do the upper and lower spacing swing of relative support, and, spacing between two adjacent quiet filter discs is slightly larger than the thickness of dynamic filter and between quiet filter disc and dynamic filter, forms the gap that water supply stream passes through.The major advantage of this technical scheme is that water outlet is directly flowed out from the gap of filter disc group, avoid the abrasive action of mud to quiet filter disc and dynamic filter, device is longer service life, this device adopts a power source just can realize Separation of Solid and Liquid simultaneously, energy consumption is lower, and parts arrange convenience, simple in structure, are easy to actual enforcement.
In addition, Shanghai Techase Environmental Protection Technology Inc. has proposed " folded spiral shell formula sludge dewatering equipment " by name patent application (number of patent application is 200920208027.4) on August 18th, 2009, its technical scheme comprises shell, fixed head, portable plate, helical axis, flight, screw rod, adjustment block, filtrate retracting device, give mud box, spoil disposal case, variable-frequency motor and guiding device, several ring-type fixed heads of the space of portion's arrangement in the enclosure become concentric shape with ring-type portable plate, screw rod is through the adjustment block at each fixed head edge, helical axis is through the circle centre position of each fixed head and portable plate, above helical axis, is furnished with axial integrated flight, its left and right arranges to mud box and spoil disposal case, and connect variable-frequency motor in helical axis one side, below spoil disposal case, guiding device is set, several fixed head belows arrange filtrate retracting device.The major advantage of this technical scheme is to large scale development, to reduce the processing cost of fixed head and portable plate simultaneously, thereby fundamentally reduces manufacturing cost.
Also having much with the same or similar technical scheme of above-mentioned patent application technology, is to have his own strong points, but fails all the time to solve this key issue of wearing and tearing of dynamic filter and helical axis in dewaterer.
