1 is a plan view of a kneader reactor 100 according to an embodiment of the present invention.

Referring to FIG. 1, the kneader reactor 100 may include a chamber 200, a rotation shaft 300, and a paddle 400.

First, the kneader reactor 100 may be an apparatus for generating a product by reacting raw materials. Here, the raw material may be a lactam including pyrrolidone, and the product produced by the reaction thereof may be bio nylon. The kneader reactor 100 according to the embodiment of the present invention may be a device used to manufacture bio nylon. But it is not limited thereto.

The chamber 200 may be a reaction space of a raw material. The chamber 200 may be formed in a long cylindrical shape along the horizontal direction. Thus, the chamber 200 may include an injection unit 210 into which the raw material is injected and a discharge unit 220 through which the product generated by the reaction of the raw material is discharged. In addition, the chamber 200 may include at least one screw (not shown) to supply the raw material and discharge the product.

In addition, the chamber 200 includes a first space S1 adjacent to the injection unit 210 into which the raw material is injected, a second space S2 and a second space S2 located adjacent to the first space S1. Located adjacent to and may include a third space (S3) adjacent to the discharge unit 220 for discharging the product generated by the reaction of the raw material. This will be described later.

It may include at least one rotating shaft 300 provided in the chamber 200 to rotate. The rotation shaft 300 may be provided long in the longitudinal direction of the chamber 200 so that the plurality of paddles 400 rotate. In addition, two rotation shafts 300 may be provided in the chamber 200. That is, the rotation shaft 300 may include a second rotation shaft 300b that rotates in at least one of the same and opposite directions with respect to the rotation direction of the first rotation shaft 300a and the first rotation shaft 300a. Here, the direction in which the first rotary shaft 300a and the second rotary shaft 300b rotate may be rotated clockwise, and the first rotary shaft 300a and the second rotary shaft 300b may be rotated counterclockwise. . The present invention is not limited thereto, and when the first rotation shaft 300a is rotated in the clockwise direction, the second rotation shaft 300b may be rotated in the counterclockwise direction. That is, the directions in which the first and second rotating

shafts

300a and 300b are rotated may be the same or different. In the present invention, the first rotary shaft 300a and the second rotary shaft 300b may rotate the paddle 400 in the same direction so that the raw material generates a product by reaction. In addition, a power unit (not shown) may be provided to be coupled to the rotating shaft 300 to provide power to the rotating shaft 300.

The paddle 400 is rotatably coupled to the rotation shaft 300, and a plurality of paddles 400 may be disposed in the longitudinal direction of the rotation shaft.

The plurality of paddles 400 may be inserted into the rotation shaft 300. The plurality of paddles 400 may be disposed at regular intervals, and the plurality of paddles 400 disposed on the first and second

rotational axes

300a and 300b may be alternately disposed. That is, the plurality of paddles 400 disposed on the first rotation shaft 300a and the plurality of paddles 400 disposed on the second rotation shaft 300b may be alternately disposed.

When the plurality of paddles 400 are rotated by the rotation shaft 300, the paddles 400 may be provided to be in contact with the raw materials in the chamber 200. Specifically, the paddle 400 may be in contact with the plurality of protrusions 430 to allow the raw material to produce a product by reaction. That is, the paddle 400 may allow the material to react by continuously contacting the raw material.

2 is a diagram illustrating the shape of a paddle 400 according to an embodiment of the present invention. 3 is a cross sectional view of a paddle 400 in accordance with one embodiment of the present invention.

2 and 3, at least some of the plurality of paddles 400 may include a main body 410, a through hole 420, and a protrusion 430.

The body 410 may be formed in a shape having a plurality of vertices. For example, the body 410 may be formed in an equilateral triangle shape. Since the main body 410 is formed in an equilateral triangle shape, the main body 410 may have a plurality of vertices, that is, three vertices. Thus, when the paddle 400 is rotated, the contact reaction may occur largely at the interface between the three vertices and the raw material.

In addition, the main body 410 is formed with a corner having a straight line, the amount of raw material introduced into the chamber 200 may be large. In the related art, since the main body is formed at an edge having an arc shape, the main body may occupy a relatively large volume in the chamber 200, and thus the amount of raw material introduced into the chamber 200 may be relatively small.

However, since the paddle 400 according to an embodiment of the present invention is formed in a corner having a straight line to occupy a relatively small volume in the chamber 200, the amount of raw material introduced into the chamber 200 is relatively high. There can be as many. Therefore, the amount of the raw material reacted in the chamber 200 may be increased, thereby increasing the product.

The through hole 420 may be formed at the center of the body 410 to be inserted into the rotation shaft 300. As the through hole 420 is formed at the center of the main body 410, the paddle 400 may be rotated about the rotation shaft 300. Accordingly, the paddle 400 may be rotated about the center to allow the vertices of the paddle 400 to be in contact with the three vertices of the body 410 and the raw material in the chamber 200.

The protrusion 430 may protrude from a plurality of vertices of the main body 410, and may be formed in a shape including at least one corner corresponding to the rotation trajectory of the rotation shaft 300. That is, the protrusion 430 may be formed in an asymmetrical shape and formed to be thicker than the thickness of the main body 410 to surround three vertices. Here, the protrusions 430 may have different corners at which the rotation trajectories coincide with the corners surrounding the vertices.

The protrusion 430 may be a contact point in contact with the raw material. The protrusion 430 may be formed to be thicker than the thickness of the body 410 at each vertex to increase the area in contact with the raw material. Accordingly, the protrusion 430 may serve to mix the raw materials so that the reaction of the raw materials can occur greatly.

In addition, the projection 430, as shown in Figure 3, includes a corner that the rotation trajectory of the rotation axis 300 coincide. This means that if the product produced by the reaction is, for example, a solid, the raw material may gradually solidify by the reaction. Accordingly, the rotational speed of the rotating shaft may be lowered due to the weight of the product (solid). Accordingly, the protrusion 430 may at least partially coincide with the rotational trajectory of the rotation shaft 300 such that the force applied to the product may not be greatly reduced. That is, the protrusion 430 may not stably reduce the rotational force for rotating the paddle 40 by the force acting on the product (solid), so that the reaction may occur stably.

FIG. 4 is a diagram illustrating the first space S1 to the third space S3 of the chamber 200 according to an embodiment of the present invention.

Referring to FIG. 4, at least two or more paddles 400 of the plurality of paddles 400 may be arranged at a predetermined angle. In detail, the plurality of paddles 400 disposed in the first space S1 and the third space S3 may be arranged at predetermined angles to each other. That is, the paddle 400 disposed in the third space S3 may be arranged in a direction opposite to the paddle 400 disposed in the first space S1.

For example, the paddle 400 disposed adjacent to the second space S2 and the paddle 400 disposed adjacent to the injection unit 210 among the plurality of paddles 400 disposed in the first space S1. A phase difference between vertices of and may occur. For example, the paddles disposed adjacent to the second space S2 are referred to as the second paddles 400b and the paddles disposed adjacent to the first paddle 400a and the injection unit 210. The first paddle 400a and the second paddle 400b may be arranged at a predetermined angle.

In addition, the paddle 400 disposed adjacent to the second space S2 of the plurality of paddles 400 disposed in the third space S3 and the paddle 400 disposed adjacent to the discharge unit 220 may be used. A phase difference of vertices may be generated. For example, the paddles disposed adjacent to the second space S2 are called fourth paddles 400d and the paddles disposed adjacent to the third paddle 400c and the discharge unit 220. The third paddle 400c and the fourth paddle 400d may be arranged at a predetermined angle.

Here, the predetermined angle may be 15 degrees. That is, the plurality of paddles 400 disposed in the first space S1 and the third space S3 are arranged to be twisted with each other by 15 degrees. Accordingly, the number of paddles 400 disposed in the first space S1 may be adjusted by 15 degrees. In addition, the number of paddles 400 disposed in the third space S3 may be arranged to be turned by 15 degrees, that is, the second paddle 400b may be arranged to be turned 15 degrees from the first paddle 400a, The fourth paddle 400d may be arranged at an angle of 15 degrees from the third paddle 400c.

In addition, the third paddle 400c and the fourth paddle 400d may be disposed in a direction opposite to the first paddle 400a and the second paddle 400b. That is, the plurality of paddles 400 disposed in the third space S3 are distorted in a direction opposite to the first space S1, thereby moving the raw materials, which are in contact with each other and the reaction proceeds, to the second space S2. have. That is, the third space S3 may move the raw material in which the reaction is not completed to the second space S2 so that the reaction may be completed.

5A is a table for comparing the reaction time of the kneader reactor 100 and the amount of raw materials occupying the chamber 200 according to the shape of the paddle 40 according to the exemplary embodiment of the present invention. Figure 5b is a graph showing the current value for the reaction time of the lower kneader reactor 100 according to the shape of the paddle 40 according to an embodiment of the present invention. 6 is a diagram illustrating another shape paddle 1 for comparison with the paddle 40 according to an embodiment of the present invention.

First, for convenience of description, the paddle 1 (formerly used paddle) shown in FIG. 6 is hereinafter referred to as an A paddle, and a paddle 40 according to an embodiment of the present invention is hereinafter referred to as a B paddle. It is called. In addition, a kneader reactor including a plurality of A paddles is called an A kneader reactor, and a kneader reactor in which at least a portion of the plurality of paddles is a B paddle is called a B kneader reactor.

As shown in FIG. 6, the A paddle has a plurality of vertices, the edges of which may be formed in an arc shape, and the hole coupled to the rotating shaft for rotating the A paddle is eccentric. In addition, the A paddle is formed with protrusions protruding from the plurality of vertices.

As described above, the B paddle, which is a paddle according to an embodiment of the present invention, may be formed in an equilateral triangle shape in a shape having a plurality of vertices. In addition, a hole engaged with the rotation shaft for rotating the B paddle is formed at the center. The protrusion protrudes from the plurality of vertices and includes at least one edge corresponding to the rotational trajectory.

The reaction time of the A kneader reactor and the B kneader reactor and the results of the amount of raw materials in the chamber are shown in the table of FIG. 5A. Here, the reaction conditions of the A kneader reactor and the B kneader reactor (for example, the size of the chamber, the amount of raw material to be injected, etc.) coincide.

Referring to Figure 5a, the reaction is completed by the reaction of the A kneader reactor is 330 minutes. On the contrary, the reaction completion time is 220 minutes by the reaction of the B kneader reactor. This is because in the A kneader reactor, since a plurality of paddles are eccentrically rotated, one contact portion for reacting (polymerizing) with the raw material is provided. However, since the B kneader reactor rotates around the center, there are three contacts for reacting (polymerizing) the raw materials. Accordingly, the B kneader reactor is provided with a plurality of contact portions than the A kneader reactor, so that the reaction (polymerization) time can be shortened.

In addition, the proportion of the raw materials in the chamber of the same size is 50% for the A kneader reactor and 60% for the B kneader reactor. That is, in the case of the A paddle, the volume occupied in the chamber is greater than the B paddle. Accordingly, the difference in the amount of raw material occupied in the chamber by the difference in the volume of the A paddle and the B paddle occurs. This means that the B kneader reactor can react with a relatively larger amount of raw material than the A reactor to produce a product.

A current value according to the reaction time of the A kneader reactor consisting of a plurality of A paddles and the B kneader reactor of at least some of the plurality of paddles is shown in the graph of FIG. 5B.

Referring to Figure 5b, where the x-axis is the reaction time, the y-axis is the current value.

Comparing the A kneader reactor and the B kneader reactor, it can be seen that the current value of the A kneader reactor increases rapidly after a certain time. This causes the A kneader reactor to be overloaded due to the weight of the product (solid) due to the reaction, and thus requires a large force (torque) to rotate, thereby rapidly increasing the current value required for the operation.

In contrast, the B kneader reactor has a smaller current value rising after the predetermined time than the A kneader reactor. This B kneader reactor comprises a projection comprising at least one edge corresponding to the rotational trajectory of the B paddle, in order to rotate the product (solid) by reaction. That is, the protrusion can disperse the force required to rotate the B paddle product (solid), so that a relatively small force (torque) takes to rotate.

The lower kneader reactor 100 according to an embodiment of the present invention may react with a raw material using a plurality of paddles 400. In addition, since the paddle 400 has a main body 410 formed in an equilateral triangle shape, the volume of the paddle 400 is small in the chamber 200, and thus a large amount of raw material may be injected into the chamber 200.

Furthermore, the paddle 400 includes a protrusion 430 protruding from a plurality of vertices, and the protrusion 430 may stir the raw materials in order to mix the raw materials well.

Furthermore, since the protrusion 430 includes at least one corner coinciding with the rotation trajectory of the rotation shaft 300, the protrusion 430 may stably prevent the rotation force for rotating the paddle 40 so that the reaction may occur stably. .

Therefore, the lower kneader reactor 100 according to an embodiment of the present invention can reduce the reaction time of the raw material can increase the amount of production.

Although the present invention has been described in detail with reference to exemplary embodiments above, those skilled in the art to which the present invention pertains can make various modifications to the above-described embodiments without departing from the scope of the present invention. I will understand. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims below and equivalents thereof.
