[0048] Example 1

[0049] Please refer to the following: Figure 1 and Figure 2 This embodiment is applicable to the stirring and mixing of liquids and materials. Specifically, this embodiment provides a stirring device, which includes a stirring tank 100, a stirring shaft 200 and stirring blades 300.

[0050] The mixing tank 100 is provided with a receiving cavity for containing liquid.

[0051] In this embodiment, the mixing tank 100 can be set to be an inverted cone shape, that is, the mixing tank 100 includes a first tank body 110 and a second tank body 120. The first tank body 110 is cylindrical, the second tank body 120 is an inverted cone shape, and the second tank body 120 is located below the first tank body 110. The wall thickness of the first tank body 110 and the second tank body 120 is equal.

[0052] The first tank 110 and the second tank 120 are provided with the aforementioned receiving cavity. The inner wall of the receiving cavity has a smooth transition, which reduces the restriction of resistance, facilitates the stirring of the liquid, and improves the stirring effect and stirring efficiency. In addition, the end of the first tank 110 away from the second tank 120 is an open end with a large area, which facilitates the filling of the liquid. The end of the second tank 120 away from the first tank 110 is a discharge end, which is equipped with a switch valve to control the output of the liquid.

[0053] In some other embodiments, the liquid can be output from an open end and transferred by a power pump.

[0054] It is understood that in some other embodiments, the mixing tank 100 may also be configured as a cylindrical, prismatic or other shape, and this is not limited here.

[0055] Please refer to the following: Figure 3 and Figure 4 The stirring shaft 200 extends at least partially into the receiving cavity, and the stirring shaft 200 includes a first end and a second end. The first end is provided with a feed inlet 210. Specifically, the feed inlet 210 includes a first feed inlet 211 and a second feed inlet 212.

[0056] The first feed port 211 is used to input materials. In this embodiment, the material is liquid. The first feed port 211 can input different materials one after another. The first feed port 211 can also directly input mixed materials. The input means include, but are not limited to, the principle of communicating vessels or power conveying.

[0057] The method of power transmission is described in detail here. The material is carried in a material bucket. The material bucket is connected to the first feed port 211 through a first pipeline. The first feed port 211 and the first pipeline are sealed together by a dynamic load seal. A power pump is installed on the first pipeline. When the power pump is started, the material in the material bucket can be drawn to the first feed port 211. When the power pump is stopped, the drawing stops.

[0058] The second feed port 212 is used to input compressed gas. Specifically, the second feed port 212 is connected to the external air compressor gas circuit, and can input air, nitrogen or oxygen according to different production needs.

[0059] In practical applications, the pressure inside the stirring shaft 200 should be greater than 0.1 MPa, and the flow rate of compressed gas should be 3 to 4 times the flow rate of the material to obtain the product with the best stirring effect.

[0060] The axis of the stirring shaft 200 is defined as the first axis a. Specifically, the stirring shaft 200 has a cylindrical outer shell.

[0061] Please continue reading. Figure 1 In this embodiment, the stirring shaft 200 can be set to not move horizontally relative to the first tank 110. The stirring shaft 200 is then positioned at the center of the first tank 110, with the center of the first tank 110 located on the first axis a. This ensures that the stirring shaft 200 can uniformly agitate the surrounding liquid. At this time, the size of the stirring shaft 200 and its single-stirring capacity should be subject to minimum restrictions to ensure the stirring effect of the liquid.

[0062] In some other embodiments, the stirring shaft 200 can be set to move horizontally relative to the first tank 110. The stirring shaft 200 can then be moved flexibly according to the stirring situation. When the liquid at a certain position is not stirred sufficiently, the position of the stirring shaft 200 can be adjusted in a timely manner. In this case, the size requirements for the stirring shaft 200 are relatively low.

[0063] In some embodiments, the stirring shaft 200 may be set to move vertically relative to the first tank 110 to avoid liquid stratification caused by uneven stirring.

[0064] Please refer to further information. Figure 3 The stirring blade 300 is installed at the second end of the stirring shaft 200, and each stirring blade 300 is provided with an outlet 310 communicating with the feed inlet 210. There are multiple outlets 310.

[0065] The first feed inlet 211 and the second feed inlet 212 are respectively connected to the discharge outlet 310. Therefore, a connection port 220 is also provided in the stirring shaft 200. The connection port 220 is connected to the first feed inlet 211 through the second pipe 230, the connection port 220 is connected to the second feed inlet 212 through the third pipe 240, and the connection port 220 is connected to the discharge outlet 310 through the fourth pipe 250.

[0066] Compressed gas and material begin to mix at connection port 220 to form a gas-liquid mixture. The compressed gas can dilute the material to a certain extent and initially disperse it. After the dispersed gas-liquid mixture is output from outlet 310, it can mix with the surrounding liquid more quickly, improving dispersion efficiency. In addition, the addition of compressed gas can create downward pressure inside the stirring shaft 200, effectively offsetting some of the pressure inside the stirring shaft 200 caused by the rise of the liquid level, and preventing liquid outside the stirring shaft 200 from entering the stirring shaft 200, thus avoiding material blockage at outlet 310 and maintaining the unobstructed flow of outlet 310.

[0067] In addition, since the density of gas is less than that of liquid, the compressed gas will automatically rise in the containment cavity, forming a bottom-up mixing effect inside the liquid, which better improves the uniformity of liquid mixing.

[0068] To improve the stirring speed, this embodiment has multiple stirring blades 300, which are arranged in a circular array around the stirring shaft 200. Each stirring blade 300 is provided with multiple discharge ports 310. In this embodiment, the total opening area of ​​each discharge port 310 is equal to 1-1.5 times the area of ​​the stirring shaft 200.

[0069] In some embodiments, each stirring blade 300 is further provided with a liquid guiding channel 320. The liquid guiding channel 320 is formed on the surface of the corresponding stirring blade 300, and one end of the liquid guiding channel 320 is connected to the discharge port 310, and the other end extends to the edge of the stirring blade 300. Specifically, the liquid guiding channel 320 is arranged in a parabolic shape, and the liquid guiding channel 320 extends from the discharge port 310 in a direction away from the rotation of the stirring blade 300, so that the material is thrown out along the trajectory of the liquid guiding channel 320 to achieve instantaneous uniform distribution.

[0070] Please see Figure 5 There are four stirring blades 300. The four stirring blades 300 are integrated on a bushing 400 and are mounted on the stirring shaft 200 through the bushing 400. The center line of the bushing 400 coincides with the first axis a of the stirring shaft 200, thereby reducing the shaking of the bushing 400 and improving the smoothness of the rotation of the stirring blades 300.

[0071] Each stirring blade 300 is arranged at a first angle α with the first axis a, and at least a portion of each stirring blade 300 is located on one side of the first axis a, while the remaining portion is located on the other side of the first axis a. It can be understood that each stirring blade 300 is inclined relative to the first axis a.

[0072] In this embodiment, the shape of the stirring blade 300 can be set to a flat plate, an arc, or other shapes. Here, a flat plate shape is used as an example.

[0073] Please see Figure 6 The stirring blade 300 includes a first edge 301, a second edge 302, a third edge 303, and a fourth edge 304. The first edge 301 is connected to the bushing 400. Therefore, the shape of the first edge 301 is adapted to the cylindrical outer periphery of the bushing 400, that is, the first edge 301 is arc-shaped. The second edge 302 is adjacent to the first edge 301 and is elongated. The third edge 303 is adjacent to the first edge 301 and is parallel to the second edge 302, and is also elongated. The fourth edge 304 is adjacent to the second edge 302 and the third edge 303 respectively, and is parallel to the first edge 301 and is arc-shaped.

[0074] The first axis a is set in the vertical direction, the second edge 302 is higher than the third edge 303, the discharge port 310 is located at the center of the stirring blade 300, and the guide channel extends from the discharge port 310 to the third edge 303 and opens at the third edge 303.

[0075] When the stirring shaft 200 rotates, the side of each stirring blade 300 that stirs the liquid is defined as the first side, and the side that faces away from the liquid is defined as the second side. The second side is provided with a discharge port 310. The first side bears greater pressure because it faces the liquid, while the second side has a certain suction force. This is why the discharge port 310 is set on the second side in this embodiment.

[0076] In this embodiment, when the stirring shaft 200 rotates clockwise, the second edge 302 contacts the liquid first. At this time, the lower surface of the stirring blade 300 is the first surface mentioned above, the upper surface of the stirring blade 300 is the second surface mentioned above, and the discharge port 310 is located on the upper surface.

[0077] In some other embodiments, the stirring shaft 200 rotates counterclockwise, and the fourth edge 304 contacts the liquid first. At this time, the upper surface of the stirring blade 300 is the first surface mentioned above, the lower surface of the stirring blade 300 is the second surface mentioned above, and the discharge port 310 is located on the lower surface.

[0078] In this embodiment, the material is directly output from the stirring blade 300 through the cooperation of the inlet 210 and the outlet 310. Therefore, the stirring blade 300 can stir and mix the material and liquid in the shortest time, improve the dispersion, and ensure product quality.

[0079] Example 2

[0080] Please refer to the following: Figure 7 and Figure 8 Based on Embodiment 1, this embodiment is improved.

[0081] The mixing tank 100 is also provided with a plurality of flow-blocking components 130, which are all located on the cavity wall of the receiving cavity. Specifically, each flow-blocking component 130 is located inside the first tank body 110, and the length of each flow-blocking component 130 is consistent with the height of the first tank body 110.

[0082] Each flow-blocking member 130 includes a first flow-blocking portion 131 and a second flow-blocking portion 132. The first flow-blocking portion 131 and the second flow-blocking portion 132 are arranged at a second included angle β and form an inner cavity. The second included angle β is 30° to 50°. For example, the second included angle β can be set to 45°. The first flow-blocking portion 131 and the second flow-blocking plate are two thin plates of the same size, that is, the length of the first flow-blocking portion 131 is equal to the length of the second flow-blocking portion 132, and the width of the first flow-blocking portion 131 is equal to the width of the second flow-blocking portion 132.

[0083] The first baffle 131, the second baffle 132, and the inner wall of the first tank 110 approximately form an equilateral triangle structure. According to the principle of triangle stability, the baffle 130 has good stability.

[0084] In this embodiment, the first flow-blocking part 131 is located on the left side and is provided with a plurality of first holes 1311, and the second flow-blocking part 132 is located on the right side and is provided with a plurality of second holes 1321. The second holes 1321, the first holes 1311 and the inner cavity are connected.

[0085] Multiple first holes 1311 are arranged at intervals in the vertical direction, and multiple second holes 1321 are arranged at intervals in the vertical direction. The first hole 1311 located at the top is the first first hole 1311, and so on. Similarly, the second hole 1321 located at the top is the first second hole 1321. The first holes 1311 and the second holes 1321 are staggered in the vertical direction. For example, on the projection plane in the vertical direction, the first second hole 1321 is located between the first first hole 1311 and the third first hole 1311.

[0086] When the stirring shaft 200 rotates clockwise, the liquid is slowly stirred clockwise. At this time, the liquid enters the inner cavity from the first hole 1311 and flows out from the second hole 1321, forming a cross-flow effect and improving the mixing effect.

[0087] For example, some liquid enters from the first hole 1311 and flows out from the fifth hole 1321, while some liquid enters from the fifth hole 1311 and flows out from the first hole 1321. That is, the liquid forms a cross-flow and mixed flow effect in the inner cavity.

[0088] According to the principle of triangular stability, even if the liquid has a certain flow velocity in the inner cavity, the first and second baffles can maintain a good fixed state and are not easily dispersed by the liquid.

[0089] In some other embodiments, when the stirring shaft 200 rotates counterclockwise, the liquid is slowly stirred counterclockwise. At this time, the liquid enters the inner cavity from the second hole 1321 and flows out from the first hole 1311.

[0090] Example 3

[0091] Please base on Figure 9 See Figure 4 , Figure 6 and Figure 7 Based on Embodiment 1 and Embodiment 2, this embodiment provides a stirring method, which includes:

[0092] S100. Place the liquid into the receiving cavity of the mixing tank 100;

[0093] Place 0.6 kg of the main ingredient into the receiving cavity.

[0094] S200. Start the stirring shaft 200, which drives the stirring blades 300 to start stirring the liquid;

[0095] Start the stirring shaft 200. The stirring shaft 200 drives the stirring blade 300 to stir at a speed of 300 r / min and raises the temperature of the stirring tank 100 to 80℃.

[0096] S300. Material is fed into the feed inlet 210. After the material is discharged from the discharge outlet 310, it is thrown out along a parabola and mixed with the liquid under the action of the stirring shaft 200.

[0097] Multiple auxiliary materials are added to the material tank in a certain proportion and in a certain order to form a material. Then, a power pump is used to draw the material into the first feed port 211 at a flow rate of 50ml / min. At the same time, compressed gas is delivered through the second feed port 212. The material and compressed gas are mixed in the stirring shaft 200 to form a gas-liquid mixture, which is output from the discharge port 310.

[0098] Under the rotation of the stirring liquid, the gas-liquid mixture is thrown out along the trajectory of the liquid guide channel 320, and can quickly mix with the surrounding liquid under the stirring of the stirring blade 300. At the same time, during the stirring process, the liquid forms a cross-flow effect through the action of the flow baffle 130, which further improves the dispersion.

[0099] In some other embodiments, the order in which steps S200 and S300 are performed can be interchanged.

[0100] After the reaction is complete, keep the stirred tank at 100°C for 8 hours.

[0101] Furthermore, the stirring method also includes a testing step: S400. Take out a portion of the product and use a laser particle size analyzer to determine the particle dispersion of the product.

[0102] The stirring method in this embodiment is achieved using the stirring devices of Embodiment 1 and Embodiment 2.

[0103] Compared with other types of stirring devices, the stirring device provided in this embodiment has a good dispersion index. To this end, according to the variable control method, this embodiment provides six other types of stirring devices and tests them with the stirring device provided in this embodiment. The test results are shown in Table 1 below.

[0104]

[0105]

[0106] Table 1

[0107] Note: In the indicators, D10 refers to the particle size at which the cumulative distribution is 10%, meaning that particles smaller than this size account for 10% of the total particle volume. D50 refers to the particle size at which the cumulative distribution is 50%. Also called the median diameter or median particle size, this is a typical value representing particle size. This value accurately divides the population into two equal parts, meaning that 50% of the particles are larger than this value and 50% are smaller than this value. If a sample's D50 = 5 μm, it means that among all the particle sizes that make up the sample, particles larger than 5 μm account for 50%, and particles smaller than 5 μm also account for 50%. D90 refers to the particle size at which the cumulative distribution is 90%, meaning that particles smaller than this size account for 90% of the total particle volume.

[0108] The lower the dispersion index, the more significant the dispersion effect. The formula for calculating the dispersion index is as follows:

[0109]

[0110] As shown in Table 1, the D90 of the stirring device in this embodiment is 0.1738, indicating that among all the particles of the sample, particles smaller than 0.1738 μm account for 90%, and the dispersion index is 0.51. This shows that compared with other types of stirring devices, the stirring device provided in this embodiment has a good dispersion index and can meet the production requirements of the product.

[0111] In addition, this embodiment also includes a particle size report chart of the experimental product obtained from the test. Figures 10 to 16 The product particle size reports for the high-speed mixing type, the four-blade inline type, the three-blade paddle type, the anchor plate type, the pitch scraper type, the six-blade disc type, and the mixing device of this embodiment are shown in turn. It can be seen from the various figures that, under the same conditions, the product dispersion index of the mixing structure of this embodiment is very small and the dispersion effect is very obvious.
