Description

Stirring device including blades {STIRRING DEVICE INCLUDING BLADE}

The present invention relates to a stirring device including a blade, and more particularly, to a stirring device including a blade for physically stirring to mix a material to be stirred.

As a stirring device for mixing materials, a device called a kneader or a mixer is known. Among these stirring devices, in order to mix high-viscosity materials such as semiconductor paste, rubber, and silicon, a type of directly stirring the material while rotating a physical component such as a blade is used.

As a prior art, an example of a stirring device according to Korean Patent Application Laid-Open No. 10-2020-0072801 is shown, in which three blades rotate about each rotational axis, and at the same time, a plan view of a configuration in which the three blades rotate about the common center of the axis is shown as

Here, the former rotation is referred to as rotation, and the latter rotation is also referred to as orbit.

In this prior art, all three blades have the same rotational direction, and are arranged and rotationally driven so that the blade tips do not collide with each other in each blade. In addition, since the radial edge of each blade is spirally formed along the rotation axis, it has the effect of pushing the material through rotation and lifting it along the spiral at the same time. A stirring device having such a blade disperses the material while stirring the high-viscosity material, and also has the effect of compressing or shearing between the blades, so that the effect of pulverizing the material can also be obtained.

However, for example, in a technical field such as the development and manufacture of an all-solid-state secondary battery, the material to be stirred is in the form of a particle or a powder, and thus, there is a need for a stirring device having an action and effect different from that of a conventional stirring device. For example, when a mixed powder containing PTFE is stirred with a stirring device according to the prior art, the PTFE particles only receive shear force in a narrow area along the edge of the blade and are only broken into small pieces, and the rubbing effect is not sufficient, so they do not form into fibers, so that in the mixture does not fully exhibit its unique properties. This is interpreted as the cause of the lack of compressive and shear forces applied to the material to be stirred.

Therefore, in recent years, in order to improve the compressive force and shear force applied to the material to be stirred, a method of stirring by applying two stirring blades to the inside of a container that provides a place to stir the material is also used, but in the prior art, two stirring blades are used. Because the material is rotated at the same speed, it was not possible to bring the material pushed out to the side (inner wall) side of the container by the rotation of the stirring blade in the process of stirring the material again between the two stirring blades. There is an impossible problem.

On the other hand, the above-mentioned background art is technical information that the inventor possessed for the derivation of the present invention or acquired in the process of derivation of the present invention, and it cannot be said that it is necessarily a known technique disclosed to the general public before the filing of the present invention. .

The first stirring blade 10 may include a first rotating shaft 10a and a plate 11 formed to protrude from the first rotating shaft 10a and rotated together with the first rotating shaft 10a.

The plate 11 may be formed of at least one or more, and the figure shows an example in which three are applied and arranged at regular intervals along the circumference of the first rotational shaft 10a.

A stirring device including a blade according to an embodiment of the present invention rotates around a first rotational shaft 10a, and the first rotational shaft 10a is a ring gear 30, a first gear 40, and a second gear It rotates and orbits through (50).

The plate 11 may be formed in a plate shape attached to protrude radially from the first rotation shaft 10a, and serves to stir and stir the material.

All three plates 11 are radially disposed on the first rotational shaft 10a.

In addition, the plate 11 may be disposed at equal intervals on the first rotation shaft 10a.

In this case, the angle α formed between the positions of each plate 11 about the first rotation axis 10a may be 120 degrees.

Each plate 11 may have a plate shape that is spirally twisted toward the lower end 112 starting from the upper end 111 in the drawing direction. In particular, the shape shown in FIG. 1 has a planar shape in which both the upper end 111 and the lower end 112 of one plate 11 are perpendicular to the first rotation axis 10a and extend between the upper end 111 and the lower end 112 . Although the plate surface 113 is exemplified in a twisted shape of a rectangular plate as forming a spiral curved surface, the shape of the plate 11 is not limited to a helical shape and may be a plate shape of another type. However, since the lower end 112 of one plate 11 comes into contact with the bottom surface of a container (not shown) for accommodating the material to be stirred, at least the lower end 112 can form a plane perpendicular to the first rotational shaft 10a. have

The radially outer end 114 extending between the upper end 111 and the lower end 112 of the plate 11 also forms a spiral like the plate surface 113 . The outer end 114 may have a cross section perpendicular to the first rotation axis 10a as shown in FIG. 1 , and may be sharply formed outward in the radial direction. In this case, the inner angle β of the sharp part of the outer end 114 may be 120 degrees.

At this time, since the fibrosis or shearing force of the material can be adjusted according to the inner angle β of the sharp part of the outer end 114, in a stirring device including a blade according to an embodiment of the present invention The inner angle of the outer end 114 may be set to various angles such as 120 degrees or more or less.

Meanwhile, in the drawings, each plate 11 is illustrated as following a spiral such as a right-handed screw, but may follow a spiral such as a left-handed screw.

As shown in FIG. 2 , in the stirring device including the blade according to an embodiment of the present invention, all three plates 11 may be formed in a plate shape.

As another example, a through hole 11a may be formed in at least one plate 11 of the three plates 11 .

That is, as shown in FIG. 1 , a through hole 11a is formed in only one plate 11 among the three plates 11 , or a through hole 11a is formed in all plates 11 as shown in FIG. 3 . This can be formed.

In addition, although not shown in the drawings, the through-hole 11a may be formed only in any two plates 11 .

The through hole 11a may be formed in a portion except for the upper end 111, the lower end 112, and the outer end 114 of the plate shape formed by the plate 11, and the material in the circumferential direction through the through hole 11a. is allowed to pass through.

In particular, when the through-holes 11a are formed in all of the three plates 11, the respective through-holes 11a communicate with each other, so that the first rotational shaft 10a may also be omitted in the region. In this case, the first rotation shaft 10a exists only in the upper part 111 and the lower end 112 part. An example of this is illustrated in Figure 4 above.

The existence of the through hole 11a allows the material to be stirred more uniformly instead of partially weakening the pressing force and shearing force by the plate surface 113 of the plate 11 .

Such a first stirring blade 10 can press and transfer the material even between the plate surfaces 113 of each plate 21 between the neighboring second stirring blades 20 to be described below, so that the powder material is stirred more suitable for

Meanwhile, the second stirring blade 20 may include a plate 21 that is formed to protrude from the second rotation shaft 20a and the second rotation shaft 20a and rotates together with the second rotation shaft 20a.

The plate 21 may be formed of at least one or more.

As an example, the plate 21 is applied in three as shown in FIGS. 1 to 3 and may be arranged at regular intervals along the circumference of the second rotation shaft 20a.

A stirring device including a blade according to an embodiment of the present invention rotates around a second rotational shaft 20a, and the second rotational shaft 20a is a ring gear 30, a first gear 40, and a second gear It rotates and orbits through (50).

The plate 21 may be formed in a plate shape attached to protrude radially from the second rotation shaft 20a, and serves to stir and stir the material.

All three plates 21 are radially disposed on the second rotation shaft 20a.

In addition, the plate 21 may be disposed at equal intervals on the second rotation shaft 20a.

In this case, the angle α formed between the positions of each plate 21 about the second rotation shaft 20a may be 120 degrees.

Each plate 21 may have a plate shape that is spirally twisted toward the lower end 212 starting from the upper end 211 in the drawing direction. In particular, the shape shown in FIG. 2 has a planar shape in which both the upper end 211 and the lower end 212 of one plate 21 are perpendicular to the second rotation axis 20a and extend between the upper end 211 and the lower end 212 . Although the plate surface 213 is exemplified as a twisted rectangular plate as forming a spiral curved surface, the shape of the plate 21 is not limited to a helical shape and may be a plate shape of another type. However, since the lower end 212 of the one plate 21 comes into contact with the bottom surface of a container (not shown) for accommodating the material to be stirred, at least the lower end 212 can form a plane perpendicular to the second rotation axis 20a. have

The radially outer end 214 extending between the upper end 211 and the lower end 212 of the plate 21 also forms a spiral like the plate surface 213 . The outer end 214 may have a cross section perpendicular to the second rotation axis 20a as shown in FIG. 9 to be sharply formed outward in the radial direction. In this case, the inner angle of the sharp part of the outer end 214 may be 120 degrees.

Meanwhile, although each plate 21 is illustrated as following a spiral such as a left-handed screw, it may follow a spiral such as a right-handed screw.

At this time, the spiral direction of the plate 11 of the first stirring blade 10 and the spiral direction of the plate 21 of the second stirring blade 20 may be different or the same as each other.

That is, if the plate 11 of the first stirring blade 10 is a right-handed screw, the plate 21 of the second stirring blade 20 is formed as a left-handed screw, and the plate 11 of the first stirring blade 10 is If is a left-handed screw, the plate 21 of the second stirring blade 20 is formed of a right-handed screw.

And, in Figs. 1 to 4, the plate 11 of the first stirring blade 10 is formed in the right-hand screw direction, and the plate 21 of the second stirring blade 20 is formed in the left-hand screw direction. .

Although not shown in the drawings, in the stirring device including a blade according to an embodiment of the present invention, all of the three plates 21 of the second stirring blade 20 may be formed in a plate shape.

As another example, a through hole 11a may be formed in at least one plate 21 among the three plates 21 .

That is, as shown in FIGS. 2 and 3 , through-holes 21a are formed in all plates 21 , or through-holes 21a are formed in only one plate 21 as shown in FIG. 1 . can

In addition, although not shown in the drawings, the through hole 21a may be formed only in any two plates 21 among the three plates 21 .

The through hole 21a may be formed in a portion except for the upper end 211, the lower end 212, and the outer end 214 of the plate shape formed by the plate 21, and the material in the circumferential direction through the through hole 21a. is allowed to pass through.

In particular, when the through-holes 21a are formed in all of the three plates 21 , the respective through-holes 21a communicate with each other, so that the second rotation shaft 20a may also be omitted in the region. In this case, the second rotation shaft 20a exists only in the upper part 211 and the lower end 212 part.

The existence of the through hole 21a allows the material to be stirred more uniformly instead of partially weakening the pressing force and shearing force by the plate surfaces 113 and 213 of the plates 11 and 21 .

On the other hand, Figure 4 shows another embodiment of the plate 21 of the second stirring blade 20, the plate 21 may be formed as one.

In this case, the plate 21 may have a twisted lip shape.

In addition, the plate 21 may be formed in a substantially semi-circular cross-sectional shape viewed from one side.

Accordingly, a space S performing the same function as the aforementioned through hole 21a is formed inside the plate 21 of FIG. 4 .

On the other hand, the first stirring blade 10 and the second stirring blade 20 have respective first and second rotational shafts 10a and 20a arranged parallel to each other, and one plate of the first stirring blade 10 ( The radially outer end 114 of 11) may be disposed to be positioned between a pair of adjacent plates 21 of the second stirring blade 20 .

The first stirring blade 10 and the second stirring blade 20 rotate (rotate) in opposite directions about the first rotation shaft 10a and the second rotation shaft 20a, and the distance between them is, for example, 3mm. This interval can be adjusted by changing the distance between the rotation axis of the first stirring blade 10 and the rotation axis of the second stirring blade 20 according to the characteristics of the stirring object and the desired stirring effect.

On the other hand, the first stirring blade 10 includes a plate 11 having one through hole 11a, and the second stirring blade 20 also includes one plate 21 having a through hole 21a formed therein. If included, the plate 11 in which the through hole 11a of the first stirring blade 10 is formed and the plate 21 in which the through hole 21a of the second stirring blade 20 is formed is another plate during mutual rotation. are arranged so that they can be directly adjacent to each other without intervening therebetween.

Then, in the process of rotating the plates 11 of the first stirring blade 10, the through-holes 11a and 21a may be adjacent to each other, and the material is stirred instead of reducing the pressing force and shearing force once per rotation of the stirring blade. increasing effect can be obtained.

And, as shown in FIG. 4 , the first stirring blade 10 includes a plate 11 having one through hole 11a among the three plates 11 , and the second stirring blade 20 is If only one plate 21 is included, the plate in which the through hole 11a of the first stirring blade 10 is formed and the plate in which the space S is formed are the plates of the other first stirring blade 10 during mutual rotation. are arranged so that they can be directly adjacent to each other without intervening therebetween. Then, in the process of rotating the plates of the first stirring blade 10, the through hole 11a and the space S may be adjacent to each other, and the material may reduce the pressing force and shear force at least once per rotation of the stirring blade. The effect of increasing agitation can be obtained.

9 is a schematic plan view showing the operating state of the embodiment of the first stirring blade 10 and the second stirring blade 20, when proceeding from the left side of the drawing to the right, the rotation of each stirring blade (10, 20) sequentially is shown as When the first stirring blade 10 rotates counterclockwise and the second stirring blade 20 rotates clockwise, in the state of (a), the material in area A is the plate of the second stirring blade 20 ( 21), and start to be compressed and stirred between the plates 11 of the first stirring blade 10 . The material in area A is compressed between the plates of each plate while going through the states of (b) and (c), and begins to come out through the states (d) and (e). In this process, each stirring blade (10, 20), the relative speed and direction of motion continuously change, so it can be stirred while receiving not only compressive force but also shear force.

And, when the first stirring blade 10 rotates clockwise and the second stirring blade 20 rotates counterclockwise, that is, the first stirring blade 10 and the second stirring blade 20 are opposite to each other. When rotating in the direction of rotation, the material is pushed from the inside to the outside of the plate to a large area, thereby maximizing the fibrosis phenomenon.

Furthermore, when the first stirring blade 10 and the second stirring blade 20 rotate in opposite directions, the material moves from the lower end of the plate to the upper end (upward arrow direction) as shown in FIG. It is sheared while riding the curve of

In addition, since the plate 11 of the first stirring blade 10 and the plate 21 of the second stirring blade 20 are arranged at regular intervals, the fiberization phenomenon of the material can be maximized.

10 is a perspective view showing the distribution of shear force acting on the stirring blade rotating in the clockwise direction along the arrow, for example, the second stirring blade 20, in sequence from the left, the stirring blade without the through hole, the plate having the through hole A single blade for stirring is illustrated, and a blade for stirring in which a through hole is formed in all plates and the axis of rotation is omitted in the corresponding area. Here, the closer to red, the greater the shear force (eg, plate surface), and the closer to blue, the less shear force. In short, it can be seen that the influence of each plate) is large. However, since the effect of compressive force or shear force needs to be applied differently depending on the characteristics of the material, it is possible to selectively apply the case where there is no through hole or there are 1 to 3, respectively.

On the other hand, the ring gear 30, the first gear 40, and the second gear 50, while simultaneously rotating the first stirring blade 10 and the second stirring blade 20, the second stirring blade 20 1 Performs a function of rotating at a faster speed than the stirring blade (10).

The ring gear 30 is disposed above the detachable rotary shaft of the first and detachable rotary shaft 10b and the second rotary shaft 20a of the first rotary shaft 10a, and gear teeth are formed at regular intervals along the inner periphery.

That is, the first rotary shaft 10a is to include a first removable rotary shaft 10b, the first removable rotary shaft 10b is detachably coupled to the hollow formed on the upper side of the first rotary shaft (10a).

And, the second rotary shaft (20a) is to include a second removable rotary shaft (20b), the second removable rotary shaft (20b) is detachably coupled to the hollow formed in the upper side of the second rotary shaft (20a).

At this time, a certain region of the portion located on the upper side of the first stirring blade 10 of the first detachable rotary shaft 10b is located in the inner space of the ring gear 30, and the second detachable rotary shaft 20b is a first detachable type It is formed to have a shorter length than the rotation shaft 10b and is located outside the ring gear 30 .

And, a portion of the first removable rotary shaft 10b and the second removable rotary shaft 20b is located inside the rotary guide tube 60, and the inside of the rotary guide tube 60 is a first removable rotary shaft (10b) and a second 2 A ball bearing (B) for smoothly rotating the removable rotary shaft (20b) is provided.

The first removable rotary shaft 10b and the second removable rotary shaft 20b rotate and revolve, and the rotary guide tube 60 rotates in place in conjunction with the rotation of the first removable rotary shaft 10b and the second removable rotary shaft 20b do.

The first gear 40 is mounted on the upper side of the first removable rotary shaft 10b. The first gear 40 may be formed as a pinion gear, and gear teeth meshed with the gear teeth of the ring gear 30 are formed at regular intervals on the outer periphery.

Accordingly, the first gear 40 moves while rotating along the inner periphery of the ring gear 30 .
