[background technology]
Chinese invention patent 200780018706.9 discloses a kind of folded spiral shell formula equipment for separating liquid from solid, possesses the solid-liquid separation portion having adjacent multiple fixing plate and multiple movable platens of being arranged between this adjacent fixing plate, with this solid-liquid separation portion through at least one screw rod extending, this movable platen is formed through the screw rod of rotation and promotes above-mentioned movable platen, and while making the object to be processed entering in above-mentioned solid-liquid separation portion move towards the outlet in solid-liquid separation portion by the screw rod rotated, while making the filtrate separated from this object to be processed pass through to discharge the solid-liquid separation portion in solid-liquid separation portion.
Movable platen is driven by helical axis, owing to helical axis contacts with movable platen, can cause the deformation of helical axis and movable platen, further result in the overload operation of machine, not be suitable for the material easily hardened.Movable platen and helical axis advance the direction of mud to be in vertical distribution, and helical axis, when advancing material progressive, can be subject to certain stop.Partial sludge is caused to push ahead swimmingly.Time helical axis advances movable platen travelling, movable platen can be allowed to press close to fixing plate above, cause near the port of export almost without gap, and excessive near the gap of mud inlet end, it is easy to cause some grains of sand or rubbish to be pinned by filter seam, also result in filtrate clean not.If encountering the material having certain paste property, being easy for causing that the fixing seam of filter between plate and movable platen blocks, or meeting some materials being inherently not easy to filter that too little filter seam can affect the normal filtration of water on the contrary.Further, owing to movable platen contacts with helical axis, cause wearing and tearing therebetween.
[summary of the invention]
The technical problem to be solved is in that to provide a kind of compact conformation, screw grid dewaterer without consumable accessory and good working effect.
The present invention is achieved in that
A kind of screw grid dewaterer, the cavity formed including the retainer ring of multiple continuous stackings or interval stacking and a helical axis of this cavity through；
The surrounding of described retainer ring is fixed by pillar, forms filter seam by the distance piece on described pillar between retainer ring and the retainer ring of described interval stacking；
Described helical axis includes central shaft, is perpendicular to the helical blades that the axle lamination of multiple stackings of central shaft is formed；
The axle lamination of the corresponding position of the filter seam formed between the retainer ring of interval stacking is major axis lamination, it is possible to embed and clean filter seam；
Being short axle lamination at the axle lamination within the retainer ring of continuous stacking, its external diameter is less than the internal diameter of described retainer ring；
Described cavity is respectively equipped with charging aperture and discharging opening.
Further, described retainer ring is oval, and the shortest outer radius of this ellipse and the longest inside radius are equal.
Further, one adjustable back pressure plate is set in described discharge outlet, to allow the material fully extracted to discharge from the gap of described adjustable back pressure plate.
Further, part or all of described helical axis is the interrupted helical axis of double end.
Further, corresponding its retainer ring of position of discontinuously locating of described interrupted helical axis has inwardly projecting shape structure, and the inwardly projecting shape structure formation in the retainer ring of continuous stacking is scraped aixs cylinder and risen.
It is an advantage of the current invention that: 1, grid solid-liquid separation and solids conveying extruding integrated design, spaces compact.2, for be not easy to run material material can treatment effeciency high, for easily sticking with paste the material filtering seam, it is ensured that filter seam does not block.3, conveying material is more strong.4, there is no consumable accessory.

[detailed description of the invention]
First embodiment:
As shown in Figures 1 to 4, a kind of screw grid dewaterer, the cavity formed including adjacent multiple retainer ring 1 and a helical axis 2 of this cavity through；Described retainer ring 1 is circular, and the surrounding of described retainer ring 1 is fixed by pillar 3, arranges distance piece 4 by described retainer ring 1 alternately on pillar 3, and forms filter seam；Described helical axis 2 includes central shaft 21, is perpendicular to the helical blades that the axle lamination 22 of multiple stackings of central shaft is formed；The axle lamination 22 major axis lamination of the corresponding position of the filter seam formed between retainer ring, it is possible to embed and clean filter seam；Being short axle lamination at the axle lamination within retainer ring 1, its external diameter is less than the internal diameter of retainer ring 1.
Described cavity be respectively arranged at two ends with charging aperture 5 and discharging opening 6.One adjustable back pressure plate 7 is set at discharging opening 6 place, to allow the material fully extracted to discharge from the gap of described adjustable back pressure plate 7.
When motor 8 rotates time, driving helical axis 2 movable, promote material to advance, meanwhile, the rubbish in filter seam cleared up in time by the major axis lamination 22 on helical axis 2, it is ensured that filter seam does not block.Additionally, due to the effect of back pressure plate 7, the rubbish fully extracted only is allowed to discharge from the gap of back pressure plate 7.
