Abstract

The utility model discloses a reaction kettle which comprises a kettle body and a stirrer arranged on the kettle body, wherein a stirring shaft of the stirrer is rotatably assembled at the bottom of the kettle body, the lower end of the stirring shaft penetrates through the bottom of the kettle body and the part of the lower end of the stirring shaft, extending out of the bottom of the kettle body, is in transmission connection with a motor of the stirrer. The reaction kettle with the structure form can ensure that the temperature of materials automatically rises to a required reaction temperature in a stirring rotating process without depending on outside heating, thereby being simple in structure and low in cost.

Description

A kind of reactor

Technical field

The utility model relates to a kind of reactor.

Background technology

Reactor is widely used in the industries such as oil, chemical industry, medicine, food, it is the pressure vessel of completing the technical process such as sulfuration, nitrated, polymerization, condensation, rely on the paddle agitator in it that different material is stirred, make material dispersion even, thus fully reaction.

A kind of reactor is disclosed as Chinese patent CN102649041A, comprise the agitator on kettle and installation kettle, agitator comprises shaft, one end of shaft stretches in kettle and stretches on part and is installed with blade, the other end of shaft is connected with motor-driven, under the driving effect of motor, shaft band moving vane rotates together, thereby realizes the Stirring of different material in kettle.The reactor of this structure, because shaft passes the kettle top from top to bottom, kettle is stretched out also as the power intake that is connected with motor-driven in its upper end, the power intake of shaft is away from autoclave body bottom, and there is following drawback in this form: on the one hand, the part that overhangs of shaft is longer, the material that adds in upper kettle is deposited in autoclave body bottom mostly, cause the stressed maximum of shaft cantilevered end, and the distortion that easily is distorted, this just has relatively high expectations to intensity and the rigidity of shaft; On the other hand, more insufficient the closer to the stirring of the material of autoclave body bottom, even also easily cause at autoclave body bottom and stir the dead angle, especially more obvious for granular material.Therefore, the reactor of this version must rely on external heater to heat so that material reaches required reaction temperature, has increased undoubtedly cost.

The utility model content

The purpose of this utility model is to provide a kind of reactor, easily causes shaft torsional deformation and autoclave body bottom the problem at dead angle easily to occur stirring in order to solve existing reactor.

The utility model adopts following technical scheme: a kind of reactor, comprise kettle and be arranged on agitator on kettle, the shaft of described agitator rotates and is assemblied in autoclave body bottom, and the lower end of shaft passes autoclave body bottom and extension is connected with the motor-driven of agitator.

Described blade is along the axial layered arrangement of shaft, and every layer of blade forms umbrella-shaped structure, wherein on the lower the umbrella mouth of one deck blade up, the umbrella mouth down of top one deck blade.

The umbrella footpath of the described blade of one deck on the lower is maximum.

The bottom of described kettle is equipped with base, and described motor is arranged on base and by driving-chain/band and shaft and is in transmission connection.

Adopt the reactor of said structure, owing to passing autoclave body bottom and extension is connected with motor-driven in the shaft lower end of agitator, make the lower end of shaft as the power intake that is connected with motor-driven, the power intake of shaft is near autoclave body bottom, on the one hand, the part that overhangs shortens, and adds that autoclave body bottom is nearest from the support of shaft, be difficult for causing the shaft distortion that is distorted, require lower to intensity and the rigidity of shaft; On the other hand, guaranteed that the material in kettle fully stirs, and can improve to greatest extent the rollover effect of material, mixed, thereby provide necessary condition for the frictional heat of material self.The reactor of this version can make material in stirring rotary course, disobeys the heating of outer boundary and automatically rises to needed reaction temperature, and therefore simple in structure, cost is low.

Further, blade is divided into the umbrella-shaped structure of layered arrangement, and on the lower the blade of one deck the umbrella mouth up, be conducive to the upwards upset of bottom material, further improved mixing effect.

Description of drawings

Fig. 1 is a kind of example structure schematic diagram of reactor of the present utility model.

The specific embodiment

The embodiment of reactor of the present utility model: as shown in Figure 1, comprise kettle 2, on kettle 2, agitator is installed, agitator comprises that rotation is assemblied in shaft 3 autoclave body bottom, that axis extends along the vertical direction, and autoclave body bottom is passed in the lower end of shaft 3, the upper end is goed deep in kettle 2; Whole kettle 2 is arranged on base 5, also is equipped with motor 1 on base 5 simultaneously, and motor 1 is in transmission connection by the part of stretching out kettle 2 of driving-chain and shaft 3; Shaft 3 stretch into the blade 4 that the interior part of kettle 1 is installed with layered arrangement, blade 4 has three layers, every layer of blade is umbrella-shaped structure, wherein on the lower the umbrella mouth of one deck blade up, and the umbrella footpath of one deck blade is maximum on the lower, the umbrella mouth down of top one deck blade.

During application, the rotating speed High Rotation Speed that the motor-driven shaft divides with 900r/, granular material in kettle stirs rotation under the drive of blade, in whipping process repeatedly, material temperature under the effect of self friction power progressively rises, and can reach 140-160 ℃, has guaranteed the needed temperature of id reaction, reaction time is 20-30min, need to not heat by extraneous heater.

In other embodiments, motor also can be in transmission connection by driving-belt and shaft.

Claims

1. reactor comprises kettle and is arranged on agitator on kettle that it is characterized in that: the shaft of described agitator rotates and is assemblied in autoclave body bottom, and the lower end of shaft passes autoclave body bottom and extension is connected with the motor-driven of agitator.

2. reactor according to claim 1 is characterized in that: described blade is along the axial layered arrangement of shaft, and every layer of blade forms umbrella-shaped structure, wherein on the lower the umbrella mouth of one deck blade up, the umbrella mouth down of top one deck blade.
