Abstract

The invention discloses a helical ribbon stirring device for mixing sludge and an accelerant in a quick sludge dehydration system. The helical ribbon stirring device comprises a U-shaped shell, a main shaft and a plurality of helical ribbons, wherein the main shaft is arranged in the U-shaped shell; a material inlet is formed in one end of the U-shaped shell, and a material outlet is formed in the other end of the U-shaped shell; a solid helical sheet is arranged on the main shaft at the material inlet; and the plurality of helical ribbons are uniformly distributed on the main shaft between the solid helical sheet and the material outlet. By virtue of the intermittent helical ribbons, the sludge can be sheared, and furthermore, the accelerant and the sludge can be fully mixed for many times, so that the hydration reaction of the sludge can be improved; and moreover, during a working process of the stirring device, as being free of extrusion, the sludge can be loose particles conveniently. The helical ribbon stirring device has the characteristics of continuous running, high yield, low energy consumption, small size, simple structure and the like.

Description

Helix stirring device
Technical field
The present invention relates to environmental protection equipment, especially relate to the sludge stirring system in a kind of sludge dewatering system.
Background technology
The whole nation sewage treatment plant wet mud of annual discharging is more than 5,000,000 tons.A large amount of mud not stabilized, harmless treatment have become the heavy burden of sewage treatment plant, again environment have been produced secondary pollution simultaneously.For the transportation that facilitates mud, deposit and processing and utilization, must carry out further drying to the mud after preliminary hydro-extraction, with reduce mud volume and transportation management expense, and create conditions for next step recycling (as doing fuel, building materials etc.).Therefore the processed of mud is very necessary.
Existing mud dewatering method has nature mummification, mechanical dehydration and sludge drying etc.Nature drying bed simple structure, floor space people, open type, unhygienic, easily form secondary pollution.Sludge drying, energy consumption is large, invests high.
at present, extensively adopt the mechanical dehydration method both at home and abroad, but be the material of difficult dehydration due to mud, directly carry out mechanical dehydration, the dehydration difficulty, in order to solve the problem of mechanical sludge dewatering difficulty, carry out a large amount of research for the sludge dewatering key technology both at home and abroad, comparatively advanced sludge dewatering system is with sludge modification now, mechanical dehydration is integrated, it is by broken stirring system, induction system and belt filter press form, one end of induction system is fixed on the below of broken stirring system discharging opening, its other end is fixed on the frame of belt filter press, broken stirring system comprises agitating device and charging breaking mixing apparatus, be fixed with modifier adding set and mud adding set above the charging breaking mixing apparatus, its below is fixed with agitating device, be provided with the promoter adding set on agitating device.This sludge dewatering system in the course of the work, mud and modifier according to a certain percentage respectively the adding set by separately enter into breaking mixing apparatus, carrying out fragmentation in breaking mixing apparatus mixes, then enter in agitating device, mix by adding a certain amount of promoter simultaneously, be transported on belt filter press by induction system at last, and by lying device, mixed mud is evenly paved and squeeze on the conveyer belt of filter press, make the water content of mud below 50%.
The agitating device that adopts is long-shaft type, namely be provided with the flight of a continuous shape on the rotating shaft of agitating device, although adopt this device the mud of modifier and moisture 80% left and right can be able to be mixed, but in the course of the work, mud can often be kneaded, pushes water outlet and form the thickness state, like this after adding promoter, the mud that is difficult to form the discrete particles shape after the promotion hydration reaction, make mud can't enter into belt filter press and carry out processed, have a strong impact on the normal operation of dewatering system, dehydrating effect significantly descends.
Summary of the invention
The object of the present invention is to provide a kind of helix stirring device of new structure, adopt the discontinuous ribbon, on the one hand mud is carried out shear action, can make on the other hand promoter and mud carry out the abundant mixing of many bouts, improve the hydration reaction of mud, simultaneously phenomenon can not occur pushing in the course of the work, be convenient to mud and form the discrete particles shape.
The present invention is achieved in that a kind of helix stirring device, it comprises U-shaped housing, main shaft and several ribbons, described main shaft is arranged in described U-shaped housing, an end at described U-shaped housing is provided with charging aperture, be provided with discharging opening at its other end, described main shaft is connected with motor by shaft coupling, it is characterized in that: be provided with solid flight on the main shaft at described charging aperture position, several ribbons have evenly distributed on the main shaft between described solid flight and discharging opening.
Be provided with baffle plate on the main shaft between the discharging opening U-shaped housing end face close with it.
Described motor is frequency control motor.
The present invention compared with prior art has following advantage:
1. adopt the discontinuous ribbon, on the one hand mud is carried out shear action, can make on the other hand promoter and mud carry out the abundant mixing of many bouts, improve the hydration reaction of mud, simultaneously phenomenon can not occur pushing in the course of the work, be convenient to mud and form the discrete particles shape.Have continuous operation, output is high, energy consumption is low, volume is little and the characteristics such as simple in structure.
2. baffle plate is set on main shaft, can stops mud to arrive the end face of U-shaped housing, the standing part of pollution main shaft makes agitating device be in the safe operation state.
3. employing frequency control motor, the running speed that can adjust as requested main shaft is guaranteed the uniformity of output and stirring, can be convenient to realize simultaneously automated production.

The specific embodiment
Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention, and all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be limited by every claim.
As can be seen from Figure 1, a kind of helix stirring device, it comprises U-shaped housing 9, main shaft 6 and several ribbons 5, described main shaft 6 is arranged in described U-shaped housing 9, an end at described U-shaped housing 9 is provided with charging aperture 4, be provided with discharging opening 7 at its other end, described main shaft 6 is connected with motor 1 by shaft coupling 2, it is characterized in that: be provided with solid flight 3 on the main shaft 6 at described charging aperture 4 positions, several ribbons 5 have evenly distributed on the main shaft 6 between described solid flight 3 and discharging opening 7.
Be provided with baffle plate 8 on the main shaft 6 between discharging opening 7 U-shaped housing 9 end faces close with it.
Described motor 1 is frequency control motor.
in the course of the work, modifier and moisture 80% left and right mud are through in entering in U-shaped housing 9 by charging aperture 4 after just mixing, solid flight 3 pushes it forward, be fed forward over ribbon on one side and partly remain in a standstill and peel off to forward part, mix with tail mud, because ribbon is the interruption ribbon, again mud is played the effect of shearing, and the mud of discontiguous area is stuck in again the original place, along with back mud constantly forward, with the mud that lags behind mixing repeatedly, add promoter at medium position, mixing through several bouts, promoted the hydration reaction of mud, just reached the effect of mixing, in mixed process without the effect of extruding force, discharged by discharging opening 7 at last.
