As shown in FIG. 1, the stirring device of the chemical reactor according to the present embodiment includes a main body 100, a stirring means 200, and an anti-sticking means 300.

The main body 100 is provided with a receiving space (A) therein, and is formed so that a material to be stirred is introduced into the receiving space (A).

The stirring means 200 is axially coupled to the main body 100 so as to be disposed at the center in the interior of the accommodation space A, and is formed to stir the material to be stirred that has been introduced into the accommodation space A when rotating the axis.

This stirring means 200 is provided with a stirring shaft 210 and a stirring blade 220, as shown in FIG.

The stirring shaft 210 is connected to the motor M1 provided in the main body 100 and has a predetermined length and is extended to be adjacent to the bottom surface of the accommodation space A.

In addition, the stirring blade 220 is coupled to one end of the stirring shaft 210, and is formed to rotate together when the stirring shaft 210 rotates according to the driving of the motor M1 to stir the stirring target material.

Here, the stirring blade 220 is formed in the shape of a disk, and the stirring blade 222 bent upward along the outer circumferential surface and the stirring blade 224 bent downward are alternately formed, more preferably, such a stirring blade The bent portions of (222, 224) are bent to one side at an angle of approximately 15 to 45, not a right angle.

This, while the stirring blades (222, 224), which are alternately bent up and down, rotate by the stirring shaft 210, create a vortex in the central portion of the stirring target material accommodated in the accommodation space (A), so that the stirring target material is molded. This is to make it a suitable viscosity.

The anti-adhesion means 300 is axially coupled to the main body 100 so as to contact the inner wall 100a of the receiving space A, and the stirring target material accommodated in the receiving space A in the same manner as the stirring blade 220 when rotating the axis While stirring, it is formed to remove the agitation target material and the reaction material adhered to the inner wall (100a).

To this end, the anti-adhesion means 300 includes a body 310, an auxiliary stirring blade 320 and an anti-adhesion blade 330, as shown in FIG. 3.

The body 310 is coupled to one end of the rotating shaft 310a formed to surround the outer circumferential surface of the stirring shaft 210, and is spaced apart from the inner wall 100a as shown in FIG. It forms a space and is formed in a'U' shape.

Here, the body 310 is axially rotated differently from the stirring shaft 210 by the motor (M2), and preferably the rotation shaft 310a for rotating the body 310 is the stirring blade 220 to rotate. Compared to the rotational speed of the stirring shaft 210, it is rotated at a relatively low speed.

That is, the motor M2 connected to the rotation shaft 310a is a low-speed motor, and operates at about 15 to 60 rpm so that the body 310 rotates, and the motor M1 connected to the stirring shaft 210 is a high-speed motor. , The stirring blade 220 is rotated by operating at about 15 ~ 1100 rpm, which is rotated at a relatively high speed through the stirring blade 220 so that the optimum viscosity suitable for molding the material to be stirred is achieved. At the same time, the body 310 rotates at a relatively low speed so that the agitation target material and the reactant adhered to the inner wall 100a can be easily scraped off and removed by the anti-adhesion blade 330. It is for sake.

In addition, the auxiliary stirring blade 320 faces each other from the inside of the body 310 and is coupled in a horizontal direction, and rotates when the body 310 is rotated to assist the stirring of the stirring target material together with the stirring blade 220. Is formed.

These auxiliary stirring blades 320 may be combined in a pair to face each other in order to perform the above purpose, and combined in a plurality of pairs along the longitudinal direction of the inner side of the body 310 as shown in FIG. 3 It could be.

In addition, the auxiliary stirring blade 320 is fixedly coupled to each other along different angles so as to perform effective stirring assistance, and for this purpose, the body 310 is also twisted in opposite directions. It is formed to have a structure.

On the other hand, the anti-adhesion blade 330 is fixedly coupled in a plurality along the spaced space along the outer edge of the body 310, and the number of anti-adhesion blades 330 may be set, and the combination and separation are easily made. It can be assembled so that the convenience of maintenance can be improved.

These anti-adhesion blades 330 are formed so as to intersect with each other, that is, the positions of the coupling shafts 312, which are arranged to face each other with respect to the center of the body 310, and accordingly, the inner wall of the body 310 is effectively rotated. Chemicals, reactants, and products can be prevented from sticking to the entire surface of (100a).

In addition, the anti-adhesion blade 330 is disposed to be in contact with the inner wall 100a of the main body 100 forming the inner side and the bottom of the accommodation space A.

In general, the body 310 is made of a metal material to solve the problem of corrosion, but in this case, when it is rotated by direct contact with the inner wall 100a, sparks may be generated due to friction or friction, and chemical Due to the nature of the factory, even minute sparks may be exposed to fire hazards, so it is important to improve the structure to prevent such a problem from occurring, and to remove the agitation target material and the reactant adhering to the inner wall 100a.

To this end, an anti-adhesion blade 330 is coupled to the outer edge of the body 310 to prevent direct contact between the inner wall 100a and the body 310, and at the same time, the inner wall ( It is possible to remove the stirring target material and the reaction material adhered to 100a).

In other words, the anti-adhesion blade 330 is a coating solution made of any one of teflon resin, epoxy resin, fluoroplastics resin, and polyamide resin having characteristics such as chemical resistance, corrosion resistance, heat resistance, and acid resistance. It is formed by being coated on the entire surface, and accordingly, it is possible to prevent deformation or damage of the anti-spinning blade 300 when exposed to the stirring target material or removing the stirring target material and reactant material in the accommodation space (A). As a result, fire that may be caused by friction between the body 310 and the inner wall 100a is prevented in advance, and at the same time, it effectively scratches the stirring target material and the reactant adhered to the inner wall 100a during rotation. I can get rid of it.

These anti-adhesion blades 330 correspond to the shape of the main body 100, and a plurality of them are combined along different directions to effectively scrape the adhered agitation target material and reactant material, and more preferably the body 310 Corresponds to the warp angle and is joined at different angles along its rim.

In addition, the anti-adhesion blade 330 is detachably coupled to the coupling shaft 312 provided on the outer edge of the body 310.

This is to enable single replacement when any one of the plurality of anti-adhesion blades 330 coupled to the outer rim of the body 310 is damaged or worn, and through this, a plurality of Individual maintenance of the anti-stick blades 330 can be easily performed.

In addition, the anti-adhesion blade 330 may be rotatable by a predetermined angle by the coupling shaft 312, at this time, an elastic member (not shown) is coupled on the coupling shaft 312 to the coupling shaft 312 and the anti-stick blade Even when the angle of the anti-adhesion blade 330 is rotated due to friction with the inner wall 100a by connecting the 330, the elastic restoring force allows the state in contact with the inner wall 100a to be always maintained by the elastic restoring force. Accordingly, a state of friction with the inner wall 100a can be strongly formed.

In addition, the anti-adhesion blade 330 is formed to have a round outer circumferential surface facing the inner wall 100a, and is effective against the inclination of the inner wall 100a of the body 310 having a'U' shape, especially the edge of the inner wall 100a. You can respond.

That is, if the anti-adhesion blade 330 is formed in a square shape, in a state coupled to the part of the rounded body 310, the sharp edge continuously rubs against the inner wall 100a as the body 310 rotates. Therefore, since damage to the inner wall 100a may occur, it is preferable that the outer circumferential surface facing the inner wall 100a is formed to be rounded as shown in FIG. 5.

And, the anti-adhesion blade 330, as shown in Figure 6, the outer peripheral surface facing the inner wall (100a) is made of a thickness surface (330a) having a predetermined width length, such a thickness surface (330a) is the body 310 ) Is formed in a round shape in a direction inclined downward along the rotation direction.

This is to minimize damage to the edge portion facing the inner wall (100a) while making a stable rotational operation when the anti-adhesion blade (310) rotates according to the rotation of the body (310).

As a result, according to the present embodiment, by scratching the inner wall 100a, the stirring target material and the reactant material can be more smoothly removed, so that the stirring can be performed inside the accommodation space A, and the main body 100 ) Is easy to clean the inside of the inner wall (100a) can be eliminated in advance the cause of the defect caused by the sticking to the inner wall (100a).

The present invention includes a stirring blade for stirring chemical substances, and a blade coated with Teflon having characteristics such as chemical resistance, heat resistance, and acid resistance is disposed in contact with the inner wall, so that rotation with the stirring blade is possible. By doing so, it is possible to obtain a homogeneous reactant, and at the same time, it has the effect of preventing chemical substances, reactants, and products from sticking to the inner wall surface of the chemical reactor.

Accordingly, in the present invention, since the Teflon-coated blade is rotated in contact with the inner wall surface, fire that may occur as a spark due to friction between the stirring blade and the inner wall surface during rotation for stirring as in the prior art is prevented. It has an effect that can be prevented.
