Background technology
Existing device in order to solid-liquid separation, include vacuum filter, pressure filter, centrifuge, belt filter press, plate and frame(type)filter press etc., these devices are owing to adopted filter screen, mud is detained and the obstruction filter screen in the mesh of filter screen easily, reduce solid-liquid separation efficiency, and life cycle is short, also results in hand cramps for the maintenance service of device.Therefore, a kind of new helix extrusion type sludge dehydrator is invented, as the applicant's Chinese patent " helix extrusion type sludge dehydrator " formerly, its patent No. is ZL200820168066.1 (notification number is CN201309880Y), has just disclosed a kind of like this technical scheme.
This helix extrusion type sludge dehydrator comprises support, water entering section, mud extraction portion and outlet part, wherein, be penetrated with a screw shaft in the support, screw shaft is by its rotation of electric motor driving, the screw shaft outer race is provided with many group filter disk assembly, each filter disk assembly comprises a quiet filter disc of annular and an annular dynamic filter, the pitch of screw shaft blade progressively diminishes from back to front and can progressively push ahead and push and is positioned at its peripheral sewage, water entering section is within it ccontaining with the rear of screw shaft, and mud extraction portion is arranged on the position in screw shaft the place ahead, the all relative support of each quiet filter disc is fixed, each dynamic filter can be followed the spacing swing up and down that screw shaft is made relative support by the drive of a transmission rig that links to each other with the transmission of screw shaft phase, and, spacing between two adjacent quiet filter discs is slightly larger than the thickness of dynamic filter between the two and forms the gap that water supply stream passes through between quiet filter disc and dynamic filter, and outlet part is just directly formed by a plurality of gaps on the filter disk assembly.
In actual applications, because mud is to be formed by extruding by the flco that produces after sewage and the medicament hybrid reaction, have stronger viscosity, adsorptivity.When sludge dewatering equipment is worked, if the mud that is adsorbed on the dynamic and static filter disc can not in time be cleared up, in the course of time then can stop up the water space that goes out between the dynamic and static filter disc, water outlet all can be sealed up for safekeeping press filtration central area like this at device, can not in time discharge, simultaneously, also also can cause resistance water inlet, directly cause processing power to reduce, can not satisfy service requirements.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of helix extrusion type sludge dehydrator at the present situation of prior art, it can make the water space that goes out between dynamic filter, the quiet filter disc effectively be dredged, the assurance water outlet is smooth and easy, and simple in structure, easy to implement.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this helix extrusion type sludge dehydrator includes support, water entering section, mud extraction portion, outlet part, runs through and be arranged in the support and the peripheral filter disk assembly of being made up of with the setting of annular dynamic filter transpostion interval the quiet filter disc of a plurality of annulars that has the screw shaft of spiral blade and be set in described screw shaft periphery;
Wherein, the all relative support of each quiet filter disc is fixed, the support spacing swing up and down relatively of each dynamic filter, and the spacing between two adjacent quiet filter discs is slightly larger than the thickness of dynamic filter between the two and forms the gap that water supply stream passes through between quiet filter disc and dynamic filter;
It is characterized in that: all be distributed with a plurality of first friction convex tendons on the two sides of each dynamic filter along the even compartment of terrain of circumference, the spacing of adjacent two first friction convex tendons is greater than the width of the first friction convex tendon itself, also be distributed with a plurality of second friction convex tendons on the two sides of each quiet filter disc along the even compartment of terrain of circumference, the spacing of adjacent two second friction convex tendons is greater than the width of the second friction convex tendon itself;
And the friction of first on dynamic filter convex tendon rubs between the convex tendon at two second on the adjacent quiet filter disc side, and the friction of second on quiet filter disc convex tendon is also just in time between two first on adjacent dynamic filter side friction convex tendons.
The height of first, second friction convex tendon can and dynamic filter and adjacent quiet filter disc between gap length adapt, can be identical, preferably, height of first, second convex tendon that rubs can be slightly less than the gap between dynamic filter side and the adjacent quiet filter disc side.
For the mud cake that can guarantee last output comparatively concentrates, water content is lower, can do following improvement: described support has the back up pad that polylith be arranged in parallel, through hole on the back up pad of the anterior end of described screw shaft front side from support runs through, outside the anterior end of this screw shaft, also be fixed with a back pressure plate, have spacing between the back up pad of this back pressure plate and front side, described mud extraction portion just is made of the gap between the through hole of this back pressure plate and back up pad.Thereby the distance between adjusting back pressure plate and the back up pad just can be regulated the water ratio of mud cake.
Compared with prior art, advantage of the present utility model is: by at dynamic filter, the two sides of quiet filter disc are provided with the friction convex tendon, when dynamic filter up and down during spacing swing, on the dynamic filter first friction convex tendon can rub with adjacent quiet filter disc contacts side surfaces, the first friction convex tendon can scrape being adsorbed on two second mud between the friction convex tendon on the quiet filter disc side, simultaneously, the second friction convex tendon of quiet filter disc also can scrape being adsorbed in the dynamic filter two first mud between the friction convex tendon, the mud that is scraped falls into the central area of sludge dewatering equipment, be extruded discharge at last by the screw shaft conveying, solved the blockage problem between dynamic filter and the quiet filter disc well; And the design by the friction convex tendon has guaranteed the spacing between dynamic filter and the quiet filter disc effectively, has guaranteed that the sludge dewatering equipment water outlet is smooth and easy.
