Description
Technical field
The utility model relates to the environmental protection machinery apparatus field, especially relates to a kind of auger conveyor of spiral shell sedimentation centrifuge for sleeping in.
Background technology
The spiral shell sedimentation centrifuge that crouches has advantages such as separating property is good, adaptability is strong, labour intensity is little, floor space is little, maintenance cost is low, can realize airtight separating automatically continuously, is the visual plant of Separation of Solid and Liquid, classification, clarification.The spiral shell sedimentation centrifuge that crouches is applicable to the sludge dewatering of Waste Water Treatment, simultaneously also be applicable to industries such as oil, chemical industry, pharmacy, ore dressing, metallurgy, light industry, food, environmental protection, can satisfy multiple instructions for uses such as liquid phase clarification to suspended material, solid phase dehydration, a class classification.It is mainly by rotary drum, auger conveyor, and parts such as big or small end-cover axle, Y-axis bearing, differential mechanism, motor drive disk assembly, support, hood, electric control box are formed.After the rotary drum of spiral shell sedimentation centrifuge for sleeping in and auger conveyor start at full speed, because rotation produces a powerful centrifugal force field, suspension material is added in the spiral by feed pipe, material enters rotary drum by the discharge opening in the spiral cylindrical shell, under the effect of centrifugal force field, the solid-phase material that proportion is bigger is heavy to be attached on the rotatory drum wall, form the solid-phase layer of an annular, auger conveyor is under the effect of differential mechanism, make spiral and rotary drum produce a constant poor rotating speed, with the small end slag notch release of the solid phase sediment after the dehydration from the circular cone rotary drum, and the clarified solution of light specific gravity overflows from the overfall of cylindrical end, so continuously work, reach the purpose of continuous separation.
Crouch the spiral shell sedimentation centrifuge at work, and the blade of auger conveyor pushes away the solid phase slag to slag notch, and helical blade and solid phase sizing are wiped easy to wear.Prior art adopts the method protection helical blade of built-up welding tungsten carbide not frayed usually.The shortcoming of this method is: dimensional accuracy is low, the sweating heat distortion is big, tungsten carbide can come off, maintenance difficult.For this reason, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of horizontal screw centrifuge rotor [application number: 03231701.8] of sedimentation filtering integral structure, by rotary drum, spiral and compound feed arrangement constitute, compound feed arrangement is made of main feed pipe and washing lotion tube and feeds in the spiral cavity, rotary drum is by differential mechanism, the straight section rotary drum, awl section rotary drum, perforate bowl connects and composes, spiral is arranged in the rotary drum and by helical blade, spiral stack shell and spiral supporting shaft constitute, helical blade is arranged on the spiral stack shell outside, the spiral stack shell is provided with the spiral perforate, the stable poor rotating speed that has leading rotary drum during the spiral running, suspension enters after the spiral cavity, solid phase enters in the rotary drum through the spiral perforate, under centrifugal action, solid phase is separated with continuation clarification in the awl section rotary drum at the straight section rotary drum, enter the dehydration of perforate bowl inner drying after the dehydration, and wash.Clarification separates and filtration washing is all finished in the rotor that is made of rotary drum and spiral, has improved the clarity of liquid phase greatly, has reduced the moisture content of solid phase, has improved clean result, has improved production efficiency.Obviously, the auger conveyor of this scheme still exists above-mentioned technical problem.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of reasonable in design, simple in structure, and anti-wear performance is good, long service life, the auger conveyor of spiral shell sedimentation centrifuge for sleeping in easy to maintenance.
For achieving the above object, the utility model has adopted following technical proposal: the auger conveyor of this spiral shell sedimentation centrifuge for sleeping in, be arranged in the rotary drum and can under the effect of differential mechanism, rotate with the rotary drum differential, this auger conveyor comprises central tube and the helical blade that is fixed on the central tube, it is characterized in that the outer end of described helical blade is fixed with the outer rim part of hardness greater than helical blade by demountable structure.Because the outer rim part is removable, therefore when occurring damaging, can change easily, reduce use cost and maintenance difficulty greatly.
In the auger conveyor of above-mentioned spiral shell sedimentation centrifuge for sleeping in, the outer end of described helical blade is fixed with installing rack, is fixed with described outer rim part by screw on installing rack.The installing rack here usually and helical blade be same material, installing rack is convenient to the outer rim part is mounted and dismounted.
In the auger conveyor of above-mentioned spiral shell sedimentation centrifuge for sleeping in, be connected by concaveconvex structure between the outer end of described helical blade and the installing rack.This structure can effectively improve the steadiness of installing rack.
In the auger conveyor of above-mentioned spiral shell sedimentation centrifuge for sleeping in, described installing rack is weldingly fixed on the outer end of helical blade.Installing rack is welded in the outer end of helical blade earlier, and the outer rim part is anchored on the installing rack with screw, and its advantage is the dimensional accuracy height, and the sweating heat distortion is little, the outer rim part can not come off, it is replaceable, easy to maintenance to realize.
In the auger conveyor of above-mentioned spiral shell sedimentation centrifuge for sleeping in, described outer rim part is made by carbide alloy.
Compared with prior art, the advantage of the auger conveyor of this spiral shell sedimentation centrifuge for sleeping in is: 1, reasonable in design, simple in structure, anti-wear performance is good, and long service life reduces use cost and maintenance difficulty greatly.2, dimensional accuracy height, the sweating heat distortion is little, and the outer rim part can not come off.
