Abstract

The utility model discloses a double-helical-ribbon detachable high-efficiency stirrer, which comprises a polymeric kettle and a driving device, wherein the driving device comprises an explosion-proof motor, a motor frame, a flexible coupling, a gear speed reducer, a rigid coupling, a driving frame, a mechanical seal and a driving shaft, the driving shaft is connected with a stirring shaft placed in the polymeric kettle through the mechanical seal, and the other end of the stirring shaft is installed in a bottom bearing at the lower part of the polymeric kettle; and the double-helical-ribbon detachable high-efficiency stirrer is characterized in that: a group of double-helical-ribbon detachable high-efficiency oar blades with different installing angles are installed on the stirring shaft, the oar blades are divided into an upper layer, a middle layer and a lower layer, the upper layer and the middle layer are provided with double-helical-ribbon detachable high-efficiency oar blades I and double-helical-ribbon detachable high-efficiency oar blades II, the spiral directions of the double-helical-ribbon detachable high-efficiency oar blades I and the double-helical-ribbon detachable high-efficiency oar blades II are opposite, and the lower layer is provided with an anchor-type oar blade (12); and the bottom bearing is positioned and fixed through a bearing-box part and the center of a bottom flange outside the kettle. The double-helical-ribbon detachable high-efficiency stirrer has the advantages of stability and reliability in operation and small oscillating quantity and has the characteristics of high heat-exchange efficiency and high reaction speed, so that the qualified rate of reactants reaches more than 99.8 percent. The double-helical-ribbon detachable high-efficiency stirrer is adapted to the polymerization reaction with extra-high viscosity.

Description

The detachable efficient agitator of two ribbons

Technical field

The utility model relates to the polymerization reaction kettle that a vertical axis gyratory agitation device is arranged in fixed container, relate in particular to by the detachable efficient agitator of two ribbons of inlaying one group of different setting angle on the shaft.

Background technology

At present, rubber production adopts the polymerisation method, and polymerization process needs to carry out in having the polymeric kettle of agitating device.Can reaction be carried out heat exchange at a certain temperature and reach poised state, and key is mixing effect.If the whole process that material is added can accomplish to mix all the time, heat of reaction is in time uniform, then polymer quality is all right, and qualification rate can reach more than 99.8%.

The traditional mode of production mode adopts the two ribbon blades of common whole weldering system to promote flowing of jar interior material, and it is unsatisfactory to stir the heat exchange effect, tank skin often occurs and assembles thing, and material stirs phenomenons such as irregular; Common blade machined surface roughness is big, causes rotation not steady, and operation troubles is many, weak effect, and the shutdown maintenance that causes has thus caused very big waste to production.

Summary of the invention

The purpose of this utility model is to overcome a series of defectives of prior art, designs a kind of efficient agitator that has two ribbon separable blades that is used for rubber device.

Technical solution of the present utility model is achieved in that

A kind of pair of detachable efficient agitator of ribbon, comprise polymeric kettle and by fire-proof motor, the motor frame, flexible coupling, gear reduction unit, positive coupling, the transmission frame, the drive unit that mechanical seal and power transmission shaft are formed, power transmission shaft wherein is connected with the shaft that places polymeric kettle by mechanical seal, the other end of shaft is contained in the bottom bearing of polymeric kettle bottom, it is characterized in that: the detachable efficient blade of two ribbons that one group of different setting angle is housed on the shaft, this blade is divided into, in, following three layers, upper strata and middle level are detachable efficient blade I of two ribbons and the detachable efficient blade II of two ribbon, and the hand of spiral of the two is opposite; Described couple of ribbon blade I, II are fixedly connected by wheel hub I, back shaft I, interior vertical shaft and outer vertical shaft and constitute the blade skeleton; Ribbon I, ribbon II then are fixedly connected with inside and outside vertical shaft; Wheel hub II connects back shaft II, and back shaft II connects anchor formula blade, and anchor formula blade pass is crossed wheel hub III and is installed on the shaft, forms anchor formula blade.

Compared with prior art, advantage of the present utility model mainly shows:

1, the detachable efficient agitator of two ribbons is dismantled and assembled structure, easily assembling, through fine finishining and balance test, and precision height, error are little, good stability.

2, the utility model is rational in infrastructure, has guaranteed carrying out smoothly of technical process, has improved output and quality, and product percent of pass reaches more than 99.8%.
