Abstract

The utility model discloses a high-efficiency energy-saving stirrer for an aniline apparatus, which comprises an explosion-proof motor, a direct-coupling gear speed reducer, a bracket, stuffing, a drive shaft and a shaft coupling. The utility model is characterized in that the high efficiency energy-saving stirrer also comprises a stirring shaft and a threaded rod impeller fixedly installed on the stirring shaft, an impeller group which is composed of push type FP impellers, and a stable ring, wherein the push type FP impeller group of the stirrer is divided into four layers. The distances among the four layers are 488mm, 385mm and 400mm, and the distance between the push type FP impeller group and the bottom of a kettle is 632mm. The diameter of the threaded rod impeller is 420mm; the diameter of the FP impeller is phi 450mm; the second layer and the fourth layer are rotated left; the third layer is rotated right. The stable ring whose diameter is phi 315mm is arranged below the fourth layer, and the height of the stable ring is 220mm. A flow-guiding bucket and a hose are arranged outside the stirrer. The utility model utilizes the orientation flow of liquid and the heat conveyance to reduce resistance, reduces the energy consumption and enhances the yield.

Description

The energy-efficient agitator of aniline

Technical field

The utility model relates to the reactor that has gyratory agitation device in fixed container, relates in particular to the agitating device that has around a vertical axis rotation.

Background technology

What present Aniline Production adopted is the hydrogenating reduction method, nitrifying process wherein needs to finish in having the reactor of agitating device, can reaction be carried out under the flow-disturbing state reposefully, key is the effect that stirs, when nitric acid and purified petroleum benzin mix reacting balance in nitrifying process, heat of reaction can in time all be taken away, the quality of reactant is all right, just can not produce the dinitro thing, and qualification rate just reaches more than 99.5%.The old-fashioned method of Aniline Production is the iron powder reducing method, and equipment is outmoded, adopts the bel-drivenn dasher, agitator arm is foundry goods entirely, and is more coarse without processing, do not make static balancing test before the use, not at the flow-disturbing state, resistance is big, weak effect, power consumption are big, single device power consumption 15KW.Such stirrer life is also very short, just needs to change axle sleeve, and has caused very big waste to production in three months.

Summary of the invention

A series of significant deficiency at prior art, the utility model has been intended to propose a kind of energy-efficient agitator that is used for the aniline device, its technical solution is achieved in that a kind of energy-efficient agitator that is used for the aniline device, comprise fire-proof motor, reductor, support, power transmission shaft and packing seal and shaft and shaft joint, it is characterized in that this agitator also comprises the screw impeller (2) that is packed on the shaft, one group of impeller sets and stabilizing ring (9) of forming by pusher FP impeller.

Technical solution of the present utility model comprises that also described one group of impeller sets of being made up of pusher FP impeller is made up of three layers of FP impeller, and the diameter of this impeller is Φ 450mm, push type, and its angle is 23.5 °, the thickness of blade is δ=8mm.

The diameter of described screw impeller is Φ 420mm, and pitch is 230mm, and helical angle is 45 °, the thickness δ=6mm of blade.

The second layer of described one group of impeller sets of being made up of pusher FP impeller, the 4th layer rotation direction are left-handed, and the 3rd layer rotation direction is dextrorotation; The installation site of the second layer is 488mm apart from the distance of ground floor screw impeller, and the 3rd layer of spacing with the second layer is 385mm, and the 4th layer of spacing with the 3rd layer is 400mm, the tail end of agitator 632mm at the bottom of the still.

Described stabilizing ring is a disk-shaped part, and internal orifice dimension cooperates with shaft axle head diameter, and its external diameter is Φ 315mm, highly is Φ 220mm.

Compared with prior art, the energy-efficient mixing tool of the aniline that the utility model proposes has the following advantage:

1, agitator paddle is a Welding Structure, and through fine finishining and static balancing test, precision height, error are little, and install stabilizing ring additional at the end of orlop impeller, make running steadily, and oscillating quantity is no more than 1/1000 axial length.

2, gear drive, is not dallied at the efficient height; Volume is little, compact conformation, and long service life can be moved more than 5 years.

3, realize that material reaction carries out under the flow-disturbing state, energy-conservationly reach 50%, product percent of pass has reached 99.5%.
