Description

Reactor

Technical field

The utility model belongs to the fixed reactor with inner mobile element, particularly relates to a kind of reactor.

Background technology

Due to all chemical transformation of chemical enginnering process be participate in reaction medium be fully mixed into prerequisite, stirring operation need to be adopted, better effect could be obtained, reactor be namely a kind of for the production of the mix and blend in technological process, reaction etc. in one pressure vessels for the chemical industry, it is widely used in the industries such as chemical industry, food, medicine, resins synthesis. Existing reactor generally includes reactor body, stir shaft and agitating vane, and stir shaft is positioned at reactor, and is coaxially connected with reactor body, and agitating vane Spiral distribution is on stir shaft. Being mixed by each solvent of the inside by stir shaft, and then reactor is carried out temperature control, be all be heated to certain temperature usually, after reaching the reaction conditions of solvent, solvent starts reaction. But, only it is provided with whipping appts, it is mixed to get even not between solvent, causes there is the non-complete reaction of a lot of raw material, anyway effect is poor, cause the waste of resource.

So, it is badly in need of a kind of reactor making good mixing effect between solvent, to reduce the waste of resource.

Practical novel content

The purpose of this utility model is at a kind of reactor that can increase degree of mixing between solvent of offer.

In order to achieve the above object, base case of the present utility model is: reactor, comprise reactor body, stir shaft and agitating vane, described stir shaft is positioned at reactor body, and be coaxially connected with reactor body, described agitating vane Spiral distribution is on stir shaft, wherein, also comprise swivel joint and water inlet pipe, the first cavity it is provided with in described stir shaft, stir shaft is provided with some first fluid holes, and described first fluid hole is connected with cavity, and described water inlet pipe is connected with stir shaft by described swivel joint.

The principle of this base case is: first add wherein a kind of solvent in reactor, makes stir shaft immerse in solvent, then controls the temperature of reactor body so that it is reach the temperature of reaction needed. Afterwards, driving stir shaft to rotate, when solvent rotates, add another kind of solvent in stir shaft, this solvent enters in reactor through stir shaft from the first fluid hole, with the solvent reaction added before.

The useful effect of this base case is: this scheme by arranging swivel joint, ensure stir shaft rotate while, it is also possible in stir shaft, add solvent. Owing to stir shaft is in rotary state, the solvent in stir shaft under the influence of centrifugal force, thus is thrown out of stir shaft, and entering into cavity fully can react with the solvent added before. Further, the quantity of fluid hole is multiple, can enter into cavity from multiple position, be mixed to get more even. Compared with traditional reactor, this scheme does not add various reaction solvent in advance, by first adding wherein one or several solvents, when the conditions such as temperature add another kind of solvent again after reaching requirement, after the solvent that adds when entering in reactor, just can fully react. Further, utilize the centrifugal force of stir shaft, solvent is thrown away from stir shaft, it is possible to the solvent first added mixes more fully, add the degree of mixing between solvent, decrease the waste of resource.

Scheme two: based on this, scheme is preferred, is provided with the 2nd cavity in described agitating vane, described 2nd cavity is connected with the first cavity, and described agitating vane is provided with the 2nd fluid hole being connected with the 2nd cavity. The area of the solvent contacts in agitating vane and reactor is bigger, thus makes the degree of mixing between each solvent higher.

Scheme three: this is the preferred of scheme two, also comprises agitator arm, and described agitator arm is fixed on rotating paddle. Agitator arm can increase the mixing effect of reactor internal solvent further.

Scheme four: this is the preferred of scheme three, described 2nd fluid hole is evenly distributed on agitating vane. Equally distributed 2nd fluid hole makes to be mixed to get between solvent more even.

Scheme five: this is the preferred of scheme four, preferred to scheme any one of scheme three of scheme based on this, described swivel joint is single loop swivel joint. The trim of single loop swivel joint and sealing-ring are made by exotic materials, resistance to wear, life-span length, corrosion-resistant, do not leak, and compared with the swivel joint of double loop, cheaper.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model reactor embodiment 1.

Embodiment

Below by embodiment, the utility model is described in further detail:

Reference numeral in Figure of description comprises: reactor body 10, fluid inlet 103, liquid outlet 105, stir shaft 20, first fluid hole 201, agitating vane 21, agitator arm 22, swivel joint 30, liquid-inlet pipe 40, motor 50.

Embodiment 1

As shown in Figure 1, reactor, comprises reactor body 10, stir shaft 20 and agitating vane 21. Stir shaft 20 is positioned at reactor, and is coaxially connected with reactor body 10, and agitating vane 21 in the shape of a spiral, and is welded on stir shaft 20, and motor 5010 is connected on the output terminal of stir shaft 20. Wherein, swivel joint 30 and water inlet pipe is also comprised. Being provided with the first cavity in stir shaft 20, stir shaft 20 is provided with some first fluid holes 201, and the first liquid outlet 105 being positioned at stir shaft 20 bottom is uniformly distributed. First fluid hole 201 is connected with cavity, and water inlet pipe is connected by stir shaft 20. In addition, agitating vane 21 being also welded with agitator arm 22, this agitator arm 22 can increase stirring area, thus strengthens the effect of stirring.

When specifically working, in reactor, first add wherein a kind of solvent, make stir shaft 20 immerse in solvent, then control the temperature of reactor body 10 so that it is reach the temperature of reaction needed. Afterwards, driving stir shaft 20 to rotate, when solvent rotates, add another kind of solvent in stir shaft 20, this solvent enters in reactor through stir shaft 20 from the first fluid hole 201, with the solvent reaction added before. This scheme by arranging swivel joint 30, ensure stir shaft 20 rotate while, it is also possible in stir shaft 20, add solvent. Owing to stir shaft 20 is in rotary state, the solvent in stir shaft 20 under the influence of centrifugal force, thus is thrown out of stir shaft 20, and entering into cavity fully can react with the solvent added before. Further, the quantity of fluid hole is multiple, can enter into cavity from multiple position, be mixed to get more even. In addition, it is possible to increasing pressurizer, pressurizer is connected with liquid-inlet pipe 40, thus increase the pressure of charging solvent when charging, thus strengthen the effect of mixing.

Embodiment 2

The difference of the present embodiment and embodiment 1 is, is provided with the 2nd cavity in agitating vane 21, and the 2nd cavity is connected with the first cavity, and agitating vane 21 is provided with the 2nd fluid hole being connected with the 2nd cavity. The quantity of the 2nd fluid hole is multiple, is evenly distributed on agitating vane 21. Relative to embodiment 1, the agitating vane 21 in this scheme is bigger with the area of the solvent contacts in reactor, thus makes the degree of mixing between each solvent higher.

Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this. Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, it is also possible to make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability that the utility model is implemented. The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification sheets etc. record the content that may be used for explaining claim.
