DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] See also Figure 1-12The present invention provides a technical solution: a water-in-water coating modification method and a modification device thereof. The present solution makes corresponding improvements to the technical problems raised by the background technology, including an equipment support frame 1 and a stirring mechanism 2 fixedly installed on the equipment support frame 1, wherein a control panel is installed on the equipment support frame 1, and a staff member can control the stirring mechanism 2 by touching the buttons on the control panel, wherein the stirring mechanism 2 includes a tank body 21, an end cover 22 arranged above the tank body 21, and a stirring member 23 arranged inside the tank body 21. It is further explained that the tank body 21 and the end cover 22 are connected by bolts, the end of the stirring member 23 is located inside the end cover 22, and a motor body 3 is fixedly installed above the end cover 22. The specification mentions: Nanocellulose crystals have poor dispersibility and are easy to agglomerate. The characteristics of the nanocellulose crystals are such that in the actual preparation process, agglomeration may easily occur due to uneven stirring. Therefore, the present invention makes corresponding improvements to the above-mentioned problems. A power component 4 for driving a stirring member 23 to uniformly stir the material containing nanocellulose crystals is provided on the end cover 22, so that the nanocellulose crystals can be effectively stirred uniformly by the power component 4 to avoid agglomeration of the nanocellulose crystals. At the same time, in the process of preparing the protective colloid, hydroxymethyl ethyl cellulose needs to be added continuously in small amounts. If an operational error occurs during the addition process, the protective colloid may easily cause flocculent complex precipitation. Therefore, the present invention provides a control component 8 for controlling the continuous addition of small amounts of hydroxymethyl ethyl cellulose on the stirring member 23.

[0037] Specifically, in the process of adding nanocellulose crystals, the motor body 3 uses the power component 4 to stir the nanocellulose crystals in the mixture evenly to achieve the purpose of modification. At the same time, in the process of preparing the protective colloid, water, aluminum sulfate, ferric chloride, hydroxymethyl ethyl cellulose and sodium pyrophosphate need to be added in sequence according to the raw material ratio, and stirred for 10 minutes to allow each component to be fully dissolved. During the addition process, hydroxymethyl ethyl cellulose needs to be added continuously in small amounts, and in order to avoid the formation of flocculent complexes, the hydroxymethyl ethyl cellulose is added evenly through the control component 8.

[0038] In this solution, the power assembly 4 includes an arc track 41 fixedly mounted on the end cover 22, and a plurality of electromagnet bodies 42 are mounted inside the arc track 41, wherein the output end of the motor body 3 passes through the top of the end cover 22 and extends into the inside thereof, and the output end of the motor body 3 is connected to a rotating shaft 43, and a through column 44 is fixedly mounted on the rotating shaft 43, wherein a driving member 45 is symmetrically arranged inside the through column 44, and the driving member 45 in this solution includes a hydraulic sleeve symmetrically mounted inside the through column 44 and used to store hydraulic oil. 451, wherein a push column 452 is installed on the hydraulic sleeve 451 (one end of the push column 452 is inside the hydraulic sleeve 451), and the other end is located outside the through column 44, a magnet 453 for generating a repulsive force with the electromagnet body 42 is installed at the end of the push column 452, and a disc body 454 is fixedly installed on the push column 452, a return spring 455 is connected between the disc body 454 and the hydraulic sleeve 451, and a hydraulic pipe 456 is connected to the end of the hydraulic sleeve 451.

[0039] Specifically, the motor body 3 is started, and the rotating shaft 43 is driven to rotate through the output end, so that the through column 44 on the rotating shaft 43 moves synchronously. During the rotation process, when the through column 44 rotates to the arc track 41, the electromagnet body 42 on the inner wall of the arc track 41 acts on the magnet at the end of the pushing column 452 (giving it a repulsive force), and the pushing column 452 squeezes the hydraulic oil inside the hydraulic sleeve 451. At this time, the reset spring 455 is in a compressed state, and the hydraulic oil is transported through the hydraulic pipeline 456.

[0040] A hydraulic storage box 46 is fixedly installed inside the rotating shaft 43, wherein the end of a hydraulic pipeline 1 456 is connected to the top of the hydraulic storage box 46, and a delivery pipeline 47 is connected to the bottom of the hydraulic storage box 46, and an annular placement member 48 is installed on the stirring member 23, and a T-shaped box body 49 is installed inside the annular placement member 48, and the end of the delivery pipeline 47 is connected to the inside of the T-shaped box body 49, and an action column 40 is installed inside the T-shaped box body 49, and the end of the action column 40 is located outside the T-shaped box body 49, and a connecting panel 401 is fixedly installed on the action column 40, and a reset spring 2 402 is connected between the connecting panel 401 and the inner wall of the rotating shaft 43, and a strip plate 6 is connected to the end of the action column 40, wherein the strip plate 6 is composed of an electromagnet. To further illustrate, the electromagnet body 42 and the strip plate 6 in this scheme The electromagnets on the plate 6 can be controlled by a program, and the amount of electricity can be set on the control panel. A transmission column 61 is fixedly installed at the end of the strip plate 6, and a hydraulic sleeve 62 is fixedly installed inside the stirring member 23, wherein the bottom of the hydraulic sleeve 62 is parallelly connected to a hydraulic pipeline 63, wherein a stirring action rod 7 is symmetrically fixedly installed on the stirring member 23, and a force sleeve 71 is fixedly installed inside the stirring action rod 7, wherein a force column 72 for directional movement through the force of hydraulic oil is installed inside the force sleeve 71; it should be noted that hydraulic oil is stored inside the hydraulic sleeve 1 451, the hydraulic pipeline 1 456, the T-shaped box 49, the conveying pipeline 47, the hydraulic sleeve 2 62, the hydraulic pipeline 2 63 and the force sleeve 71 in this scheme, and they are in a sealed state;

[0041] Further, when the through-column 44 rotates to the arc track 41, the electromagnet body 42 acts on the magnet 1 453, so that the push column 452 acts on the hydraulic oil inside the hydraulic sleeve 1 451. Since the hydraulic oil cannot be squeezed, it acts on the hydraulic oil inside the T-shaped box 49 through the delivery pipe 47, so that the action column 40 is subjected to the force to perform a directional action, and the return spring 2 402 is stretched under the action of the connecting panel 401, so that the strip plate 6 is driven to perform a directional synchronous action, and the strip plate 6 squeezes the hydraulic oil inside the hydraulic sleeve 2 62 through the transmission column 61. The hydraulic oil inside the hydraulic sleeve 2 62 is subjected to the force to transport the hydraulic oil inside the hydraulic pipe 2 63 to the inside of the force-bearing sleeve 71, and the hydraulic oil inside the force-bearing sleeve 71 transmits the force to the surface of the force-applying column 72.

[0042] The end of the force column 72 is connected to an action rack 73, and a gear body 74 for meshing with the action rack 73 is arranged inside the stirring action rod 7, wherein a transmission gear 75 and a meshing gear 76 for meshing with the transmission gear 75 are installed in parallel inside the stirring action rod 7, and a rotating column 77 for rotationally connecting with the inner wall of the stirring action rod 7 is installed on the gear body 74, the transmission gear 75 and the meshing gear 76, a baffle 79 is fixedly installed inside the stirring member 23, and a spring body 70 is connected between the action rack 73 and the baffle 79, and the transmission gear 75 is installed in parallel inside the stirring action rod 7. The radius of the wheel 75 and the meshing gear 76 are smaller than the gear body 74, and the transmission gear 75 is the same size as the meshing gear 76. The rotating column 77 on the gear body 74 and the meshing gear 76 penetrates the inner wall of the stirring action rod 7 and extends to the outside, and the rotating column 77 penetrating the inner wall of the stirring action rod 7 is installed with a stirring blade 78. Since the size of the gear body 74 is larger than the meshing gear 76, the corresponding rotation speed of the stirring blade 78 is also different. Therefore, during the stirring process, the flow rate of the stirring force inside the tank body 21 is also different, so as to facilitate the uniform stirring of the nanocellulose crystals.

[0043] Embodiment 1: During the process of adding nanocellulose crystals into the mixed liquid, the motor body 3 is started, and the stirring member 23 is driven to rotate synchronously through the rotating shaft 43, and the through-column 44 moves synchronously therewith. When the through-column 44 moves to the arc track 41, the end of the pushing column 452 inside the through-column 44 (the end containing the magnet 1 453) is subjected to the repulsive force of the electromagnet body 42, and the pushing column 452 squeezes the hydraulic oil inside the hydraulic sleeve 1 451. Since the hydraulic sleeve 1 451, the hydraulic pipeline 1 456, the T-shaped box 49, the delivery pipeline 47, the hydraulic sleeve 2 62, the hydraulic pipeline 2 63 and the force-bearing sleeve 71 mentioned above all contain hydraulic oil, and then when the hydraulic oil is incompressible, the hydraulic oil is forced into the hydraulic sleeve 1 451. Under the characteristics of contraction, the action column 40, the strip plate 6, the transmission column 61 and the force column 72 are driven in turn to perform directional actions, and the force column 72 drives the action rack 73 to mesh with the gear 76 body 74, so that the gear body 74 rotates. At the same time, the spring body 70 is in a compressed state, and the rotation of the gear body 74 drives the meshing gear 76 to rotate through the meshing transmission gear 75. Due to the different sizes between the meshing gear 76 and the gear body 74, the rotation rate of the rotating column 77 is also different accordingly, so that the rotation speed of the stirring blade 78 is different. Since the distance between the stirring blades 78 is relatively close and the stirring member 23 is in a rotating state, the nanocellulose crystals are uniformly stirred.

[0044] The control assembly 8 in this scheme includes a circular cylinder 81 fixedly mounted on the stirring member 23, and a feeding sleeve 82 is installed on the circular cylinder 81, wherein a connecting column 83 is installed inside the circular cylinder 81, and a second magnet 84 is installed at the end of the connecting column 83 close to the strip plate 6 (the strip plate 6 always generates a repulsive force on the second magnet 84 during the movement), a supporting panel 85 is installed inside the circular cylinder 81, a second spring body 86 is connected between the end of the connecting column 83 and the supporting panel 85, and a control board 87 is fixedly mounted at the other end of the connecting column 83, and a through hole 88 is provided on the control board 87. Further explanation: a feeding sleeve 82 is installed on the circular cylinder 81 , and the control board 87 is between the unloading sleeve and the feeding sleeve 82. The staff can control the power-on time of the electromagnet on the strip plate 6 through program design. When the electromagnet on the strip plate 6 is powered on to generate a repulsive force on the second magnet 84, the second magnet 84 drives the support panel 85 to perform a directional action through the connecting column 83, so that the hole is between the unloading sleeve and the feeding sleeve 82. At this time, hydroxymethyl ethyl cellulose can be added to the tank body 21. When the hole is between the unloading sleeve and the feeding sleeve 82, the repulsive force of the electromagnet on the strip plate 6 on the second magnet 84 is equal to the compressive elastic force of the second spring body 86, so that the amount of hydroxymethyl ethyl cellulose added can be controlled.
