Spiral sludge dewatering machine had had widely in sewage dehydration industry in recent years to be used, and both has been applicable to the sludge dewatering of high concentration, is applicable to again the sludge dewatering of low concentration; Simultaneously, be applicable to the sludge dewatering of the industry-by-industries such as municipal wastewater, chemical industry, printing and dyeing.
But spiral sludge dewatering machine itself has the shortcoming of oneself: the one, and the up-front investment high cost; The 2nd, stationary ring, rotating ring, helical axis have wear phenomenon in During Process of Long-term Operation, and accumulation needs after operation a period of time to change, and causes maintenance cost high.
In order better to improve the performance of spiral sludge dewatering machine, a part of unit and research staff conduct in-depth research utility model, and the research and development achievement have been carried out patent declared.More representational have: the patent easily-maintainable overlapping screwed sludge dewatering equipment that the safe Environmental Protection Technology Co., Ltd in Taizhou declares, in the patent No. 201020287795.6, a kind of easily-maintainable overlapping screwed sludge dewatering equipment has been described, comprise support, helical axis with helical blade, drive motor that this helical axis rotates and intussusception in the filter disc group of helical axis periphery, described filter disc group is comprised of several fan-shaped ring stator and rotating rings in the setting of axial direction transpostion interval, and described fan-shaped ring stator and rotating ring are respectively on corresponding back shaft and make the stator that is in same axial longitudinal section keep symmetrical with respect to the axis of screw, the stator that is in same axial longitudinal section consists of circular.
The stacked spiral type solid-liquid separator of Shanghai Rihe Environment Protection Equipment Co., Ltd.'s application, in the number of patent application 200920074199.7, a kind of stacked spiral type solid-liquid separator is disclosed, its filter body is to be made of fixed ring, rotating ring, trimmer and helical axis, helical axis directly upwards is provided with staggered fixed ring and rotating ring, gap between fixed ring and the rotating ring is by the trimmer adjustment, fixed ring is serially connected by the fixed ring boom, helical axis drives rotating ring and moves about, its innovative point is that fixed ring and/or rotating ring are to be spliced by the small pieces more than 2 or 2.
Shanghai is with the folded spiral shell formula sludge dewatering equipment of minister Environmental Protection Technology Co., Ltd application, in the number of patent application 200920208027.4, it is sludge dewatering equipment that this utility model patent discloses a kind of folded spiral shell, comprise shell, fixed head, portable plate, helical axis, flight, screw rod, adjustment block, the filtrate retracting device, give mud box, the spoil disposal case, variable-frequency motor and guiding device, several ring-type fixed heads that it is characterized in that in the enclosure section's arrangement space become concentric shape with the ring-type portable plate, screw rod is through the adjustment block at each fixed head edge, is furnished with axial integrated flight above the helical axis, arrange to mud box and spoil disposal case about device, and at helical axis one side connection variable-frequency motor, below the spoil disposal case guiding device is set, several fixed head belows arrange the filtrate retracting device.Fixed head in this patent and portable plate all are through being spliced by two or more parts.
Summary of the invention
This patent problem to be solved overcomes the deficiencies in the prior art part exactly, provides a kind of cost filter assemblies lower, the more convenient to install and spiral sludge dewatering machine that loss is less.
The utility model is achieved through the following technical solutions:
The filter assemblies of spiral sludge dewatering machine, described filter assemblies comprises holding bar, stationary ring and rotating ring; Several stationary rings and rotating ring intussusception are in the periphery of helical axis; Put a rotating ring between per two stationary rings; Described stationary ring is comprised of circumferential body and several fixedly ears that along the circumferential direction stretch out circumferential body; Each fixedly ear peg graft respectively and be fixed in the with it adaptive groove of opening on the with it corresponding holding bar; The two ends of described holding bar are fixedly connected with lower sheet with upper sheet respectively; Helical axis is parallel with holding bar; Each stationary ring has three fixedly ears at least, and holding bar quantity has three at least.
During use, because the stopping of holding bar, cause rotating ring to be limited in the spacing space that three or three above holding bars consist of.So holding bar has played the limited support effect to rotating ring.Therefore described rotating ring size is with can be spacing by holding bar, do not drop out to be standard.
Stationary ring can be formed by metal, plastics, resin casting cutting processing.The material of holding bar can form for metal, plastic processing.The fixedly ear of stationary ring increases along with the increase of stationary ring diameter, and the fixedly ear quantity on each stationary ring is identical with the quantity of holding bar, is preferably 3～16.
The utility model beneficial effect compared with prior art is: at the equipment of assurance video disc---be under the prerequisite of rotating ring, stationary ring flatness, reduced production cost; Filter assemblies---be the mode of the controlling non-bolt hole of stationary ring, without pad, save the raw material of stationary ring, because the stationary ring in original strap bolt hole needs very large bolt ear in order to guarantee the intensity of stationary ring, the waste material; In installation process, simple, convenient, efficient is high; The mode of controlling of filter assemblies has avoided the screw thread of bolt to be corroded in sewage, not easily detachable difficult point; Dynamic and static ring of the present invention is the integral type video disc, has flatness height, stable characteristics than knockdown dynamic and static ring in the aforementioned patent.
