Abstract

The utility model discloses a spiral ribbon agitating device for mixing sludge and an accelerating agent in a sludge rapid dewatering system, which comprises a U-shaped shell, a main shaft and a plurality of spiral ribbons, wherein the main shaft is installed in the U-shaped shell; a feeding port is arranged at one end of the U-shaped shell, and a discharging port is arranged at the other end of the U-shaped shell; a solid spiral plate is arranged on the main shaft at the feeding port; and the plurality of spiral ribbons are uniformly distributed on the main shaft between the solid spiral plate and the discharging port. By adopting the intermittent spiral ribbons, the sludge is cut on one hand, the accelerating agent can be fully mixed with the sludge for more times on the other hand, so that the hydration reaction of the sludge is improved; and meanwhile, the extrusion phenomenon can not occur in the working process, so that the sludge conveniently forms loose particles. The spiral ribbon agitating device has the characteristics of continuous operation, high yield, low energy consumption, small size, simple structure and the like.

Description

The ribbon agitating device
Technical field
The utility model relates to environmental protection equipment, especially relates 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.The transportation of mud for ease, depositing and processing and utilization, must carry out further drying to the mud after the preliminary hydro-extraction, reducing mud volume and transportation management expense, and is that next step utilizes (as doing fuel, building materials etc.) to create conditions again.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, form secondary pollution easily.Sludge drying, energy consumption is big, and investment is high.
At present, extensively adopt the mechanical dehydration method both at home and abroad, but because mud is the material of difficult dehydration; Directly carry out mechanical dehydration, the dehydration difficulty is in order to solve the difficult problem of mechanical sludge dewatering; Carry out a large amount of research for the sludge dewatering key technology both at home and abroad, comparatively advanced now sludge dewatering system is an one with sludge modification, mechanical dehydration, and it is made up of broken stirring system, induction system and belt filter press; 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, and broken stirring system comprises agitating device and charging breaking mixing apparatus, in charging breaking mixing apparatus upper fixed modifier adding set and mud adding set is arranged; Its below is fixed with agitating device, and agitating device is provided with the promoter adding set.This sludge dewatering system in the course of the work; Mud and modifier according to a certain percentage respectively the adding set through separately enter into breaking mixing apparatus; In breaking mixing apparatus, carrying out fragmentation mixes; Get into then in the agitating device, mix through adding a certain amount of promoter simultaneously, be transported on the belt filter press through induction system at last; And through lying device mixed mud is evenly paved and on the conveyer belt of filter press, to squeeze, the water content that makes mud is below 50%.
The agitating device that is adopted is the major axis type; Promptly the rotating shaft of agitating device is provided with the flight of a continuous shape, though adopt this device can modifier and moisture about 80% mud can be mixed, in the course of the work; Mud can often be kneaded, push water outlet and form the thickness state; After adding promoter, be difficult to form the mud of discrete particles shape behind the promotion hydration reaction like this, 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 descends significantly.
The utility model content
The purpose of the utility model is to provide a kind of ribbon agitating device of new structure; Adopt the discontinuous ribbon; On the one hand mud is carried out shear action, can make promoter and mud carry out the abundant mixing of many bouts on the other hand, improve the hydration reaction of mud; Simultaneously can not occur pushing phenomenon in the course of the work, be convenient to mud and form the discrete particles shape.
The utility model is achieved in that a kind of ribbon agitating device; It comprises U shaped shell, main shaft and several ribbons, and said main shaft is installed in the said U shaped shell, is provided with charging aperture at an end of said U shaped shell; Be provided with discharging opening at its other end; Said main shaft links to each other with motor through shaft coupling, and it is characterized in that: the main shaft at said charging aperture position is provided with solid flight, and several ribbons have evenly distributed on the main shaft between said solid flight and the discharging opening.
Main shaft between the discharging opening U shaped shell end face close with it is provided with baffle plate.
Described motor is a frequency control motor.
The utility model compared with prior art has following advantage:
1. adopt the discontinuous ribbon; On the one hand mud is carried out shear action, can make promoter and mud carry out the abundant mixing of many bouts on the other hand, improve the hydration reaction of mud; Simultaneously can not occur pushing phenomenon in the course of the work, be convenient to mud and form the discrete particles shape.Characteristics such as have that continuous operation, output are high, energy consumption is low, volume is little and simple in structure.
2. baffle plate is set on main shaft, can stops mud to arrive the end face of U shaped shell, 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 main shaft is as requested guaranteed the uniformity of output and stirring, can be convenient to realize simultaneously automated production.

The specific embodiment
Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model, and all technical schemes that are equal to also belong to the category of the utility model, and the scope of patent protection of the utility model should be limited each item claim.
As can be seen from Figure 1; A kind of ribbon agitating device; It comprises U shaped shell 9, main shaft 6 and several ribbons 5, and said main shaft 6 is installed in the said U shaped shell 9, is provided with charging aperture 4 at an end of said U shaped shell 9; Be provided with discharging opening 7 at its other end; Said main shaft 6 links to each other with motor 1 through shaft coupling 2, and it is characterized in that: the main shaft 6 at said charging aperture 4 positions is provided with solid flight 3, and several ribbons 5 have evenly distributed on the main shaft 6 between said solid flight 3 and the discharging opening 7.
Main shaft 6 between discharging opening 7 U shaped shell 9 end faces close with it is provided with baffle plate 8.
Described motor 1 is a frequency control motor.
In the course of the work, modifier and moisture 80% left and right sides mud is through in just mixed back gets in the U shaped shell 9 by charging aperture 4, and solid flight 3 pushes it forward; Be fed forward on one side above ribbon and partly remain in a standstill and peel off, mixes with tail mud to forward part, owing to ribbon for being interrupted ribbon; Again mud is played the effect of shearing, and the mud of discontiguous area is stuck in the original place again, along with back mud constantly forward; With the mud that is lagged behind mixing repeatedly, add promoter at medium position, through the mixing of several bouts; Promoted the hydration reaction of mud; Just reached the effect of mixing, the effect of no extruding force in the mixed process is discharged by discharging opening 7 at last.
