Description

Technical Field

[0001] The present invention relates to the technical field of chemical paint production, and specifically to an acrylic aqueous emulsion homogenization device. Background Art

[0002] Acrylic aqueous emulsions are widely used in fields such as coatings, adhesives, textiles, and papermaking, and their performance depends on the uniformity and stability of the emulsion. During the emulsion preparation process, it is usually necessary to go through processes such as mixing, homogenization, and cooling to ensure that the final product has good dispersibility and storage stability. However, the existing homogenization equipment still has the following technical problems in practical applications: Insufficient cooling efficiency: After searching, CN110075675A proposed an emulsion cooling tank, which uses a single water cooling cycle structure. Although it can achieve basic cooling, it lacks active stirring and auxiliary air cooling, resulting in a slow cooling speed and uneven temperature distribution. CN111569595B uses spiral guide vanes to enhance heat exchange, but still relies on a single cooling method and cannot meet the rapid cooling requirements of high-viscosity emulsions. Traditional emulsion cooling usually uses a single cooling method (such as air cooling or water cooling), with a slow cooling speed and prone to uneven temperature distribution, affecting the stability of the emulsion. In addition, there is a lack of effective stirring during the cooling process, resulting in low heat transfer efficiency and difficulty in achieving rapid and uniform cooling.

[0003] Unsatisfactory homogenization effect: The shearing force of the homogenization mechanism is single. After searching, CN112657432A uses multi-layer paddle stirring, but the size of the stirring parts is fixed and cannot form a gradient shearing force, resulting in uneven dispersion of large-particle emulsions. CN113731280B improves the dispersibility through a high-shear homogenization head, but has high energy consumption and is prone to local overheating.

[0004] Most of the existing stirring mechanisms use stirring paddles with fixed sizes, making it difficult to form a gradient shearing force, resulting in uneven distribution of emulsion particles and affecting the performance of the final product. At the same time, some equipment lacks a diversion design, with low mixing efficiency and prone to local agglomeration or precipitation. Low quantitative filling accuracy: During the emulsion transfer process, traditional equipment usually uses simple pumping or gravity drainage methods, making it difficult to accurately control the filling volume, resulting in quality fluctuations between batches and affecting product consistency. Insufficient automation: Existing equipment relies mostly on manual operations in the emulsion collection and filling processes, such as manually switching collection containers or adjusting stirring parameters, which not only has low efficiency but may also introduce human errors, affecting process stability.

[0005] Although existing patented technologies have made improvements in single functions (such as cooling or homogenization), they have not systematically solved the problem of collaborative optimization of the entire process of cooling - homogenization - filling - collection. In response to the above problems, there is an urgent need to develop a new type of acrylic water - based emulsion homogenization equipment that can achieve efficient cooling, gradient homogenization, precise filling, and automated collection to improve the stability of emulsion production and product quality.

DETAILED DESCRIPTION OF THE INVENTION

[0021] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1 As Figures 1-5 , this embodiment provides an acrylic aqueous emulsion homogenizing device, including a "[-]" shaped mounting frame 2, a cooling tank 1, a homogenizing and stirring tank 3, a homogenizing mechanism 4, and a collecting graduated cylinder 6. The cooling tank 1 is installed on the top of the "[-]" shaped mounting frame 2, and the collecting graduated cylinder 6 is placed at the bottom of the "[-]" shaped mounting frame 2. A cooling chamber is provided inside the cooling tank 1, and an addition port and a liquid outlet are provided on the cooling chamber. A stirring device is also provided inside the cooling chamber. An air-cooling chamber 12 is provided on the side of the cooling tank 1. There are two air-cooling chambers, and a fan 121 is provided inside each air-cooling chamber; a gate for opening and closing the air-cooling chamber is also provided on the air-cooling chamber; a quantitative filling mechanism is provided below the top plate 20 of the "[-]" shaped mounting frame 2, and the quantitative filling mechanism horizontally moves to fill the emulsion in the cooling tank 1 into the homogenizing and stirring tank 3; emulsion feeding hoppers 30 and accelerator feeding hoppers 31 are respectively provided on both sides of the top of the homogenizing and stirring tank 3. A guide plate 32 is provided on the inner wall of the homogenizing and stirring tank 3. A homogenizing mechanism 4 is provided inside the homogenizing and stirring tank 3 below the guide plate 32. The homogenizing mechanism 4 includes a motor I 42 installed through a sealing box 41; the output shaft of the motor I 42 passes through the sealing box 41 and is connected to a rotating shaft 43, and a plurality of stirring members 44 are installed around the rotating shaft 43. A plurality of liquid outlets 45 controlled by valves are provided at the bottom of the homogenizing and stirring tank 3; the collecting graduated cylinder 6 is placed directly below the liquid outlet 45 through a rotating base 5.

[0023] The stirring member 44 includes an "┓"-shaped connecting rod 441 and at least one spherical stirrer 442; one end of the connecting rod 441 is fixed on the rotating shaft 43, and the other end of the connecting rod 441 is connected to the corresponding spherical stirrer 442. The length of the horizontal end of the "┓" shape of the connecting rod 441 installed on the rotating shaft 43 decreases sequentially from top to bottom.

[0024] During the specific operation of homogenization, in the emulsion cooling stage, the emulsion raw material enters the cooling chamber of the cooling tank 1. The coolant is injected through the addition port and evenly flows under the action of the stirring device (the motor II 11, the stirring shaft II 13, the stirring paddle 14, and the stirring hammer 15 cooperate with each other), improving the heat exchange efficiency. At the same time, the fans 121 in the two air-cooling chambers 12 are started, and the air volume is adjusted through the gate to enhance the heat dissipation effect, quickly cooling the emulsion to a temperature suitable for homogenization. The high-efficiency composite cooling system improves the stability of the emulsion. The dual-mode collaborative cooling: adopts the combined design of the cooling chamber (water cooling) + the dual air-cooling chambers (forced convection). The air-cooling chambers are equipped with switchable gates and dual fans, and the cooling rate can be flexibly adjusted according to the emulsion viscosity. Compared with the traditional single cooling method, the cooling speed is increased, avoiding local overheating. A composite stirring structure of the stirring paddle + the stirring hammer is set in the cooling chamber to enhance the heat exchange efficiency and ensure the uniform distribution of the emulsion temperature.

[0025] In the quantitative filling stage, the cooled emulsion enters the quantitative filling mechanism through the liquid outlet. The driving member 24 (the forward and reverse motor 241, the threaded lead screw 242, and the slider 244) pushes the piston 222 to move in the diversion cylinder 221, precisely controlling the extraction and discharge amount of the emulsion. The lifting member 21 (the electric push rod) adjusts the height of the mounting plate 22 to align the discharge conduit 25 with the feeding port of the homogenizing and stirring tank 3, realizing automatic filling. The piston is driven by the threaded lead screw, and the flow rate is managed by combining the dual control valves. The filling error is ≤±0.5 mL, which is much higher than the ±5 mL accuracy of the traditional peristaltic pump. The piston stroke is precisely controlled by the forward and reverse motor to achieve quantitative transfer without manual intervention. The lifting design is adapted to multiple workstations. The filling mechanism adjusts the height through the electric push rod, flexibly docking the cooling tank and the homogenizing tank. Ensure that the filling amount of each batch is consistent, reduce raw material waste, and improve the product qualification rate.

[0026] In the homogenizing and stirring stage, the emulsion enters the homogenizing and stirring tank 3 through the emulsion feeding hopper 30, and the promoter is added through the promoter feeding hopper 31. The motor I 42 drives the rotating shaft 43 to rotate, driving the "┓"-shaped connecting rod 441 and the spherical stirrer 442 to stir at high speed. Since the length of the connecting rod 441 decreases from top to bottom, a gradient shear force is formed, enabling the emulsion and the promoter to be fully mixed. The inner wall guide plate 32 guides the material to form a vortex, further enhancing the homogenization effect and avoiding local precipitation or caking. The gradient shear homogenization mechanism is adopted to optimize the emulsion particle size distribution. The variable-diameter stirring design: the homogenization mechanism adopts a "┓"-shaped connecting rod, and the horizontal length decreases from top to bottom, forming a gradient shear force field to avoid excessive shear damage to the emulsion structure. The spherical stirrer enhances the turbulence. Compared with the traditional blade, the spherical stirrer can generate a more uniform vortex, making the emulsion particles more finely dispersed. The guide plate optimizes the flow path: a guide plate is arranged in the homogenizing and stirring tank to prevent the emulsion from short-circuiting and flowing, ensuring full mixing. The emulsion particle size distribution is more uniform, the stability is improved, it is applicable to high-solid or high-viscosity systems, and the precipitation and stratification phenomena are reduced.

[0027] In the collection stage, after homogenization is completed, the emulsion is discharged through the outlet 45. The motor III 51 of the rotating base 5 drives the worm 52 to mesh with the worm gear disk 54, driving the rotating table 53 to rotate, so that different collection measuring cylinders 6 sequentially receive the emulsion, realizing continuous production.

The stirring fan blades are connected with the stirring shaft II 13. The stirring fan blades are composed of a stirring paddle 14 and a stirring hammer 15. During operation, the motor II 11 drives the stirring shaft II 13 to rotate, and the stirring shaft II 13 drives the stirring paddle 14 and the stirring hammer 15 to move. Under the combined action of the stirring paddle 14 and the stirring hammer 15, the fluid flows evenly, improving the heat exchange efficiency.

The difference is that on the basis of Example 1, it further discloses that the quantitative filling mechanism includes a lifting member 21, a mounting plate 22, a diversion cylinder 221, a driving member 24, a discharge conduit 23 and a discharge conduit 25. The diversion cylinder 221 and the driving member are both arranged on the mounting plate 22, and the driving member 24 is connected with a piston 222 slidably arranged in the diversion cylinder 221. The feed port at one end of the diversion cylinder 221 is connected with the liquid outlet on the cooling chamber through the discharge conduit 23. The discharge port at one end of the diversion cylinder 221 is communicated with the discharge conduit 25 fixed on the mounting plate 22. Control valves are respectively arranged on the feed port and the discharge port of the diversion cylinder 221.

[0030] The lifting member 21 adjusts the height of the mounting plate 22 to align the discharge conduit 23 with the liquid outlet of the cooling tank body 1. The control valve at the feed port is opened, and the control valve at the discharge port is closed. The driving member 24 pulls the piston 222 to slide towards the rear end of the diversion cylinder 221 through the connecting rod 243, forming a negative pressure. The emulsion is sucked from the cooling tank body 1 into the diversion cylinder 221 through the discharge conduit 23, completing quantitative extraction. When filling the emulsion, the control valve at the feed port is closed, and the control valve at the discharge port is opened. The lifting member 21 adjusts the height of the mounting plate 22 to align the discharge conduit 25 with the feeding port of the homogenizing stirring tank 3. The driving member 24 pushes the slider 244 forward, and pushes the piston 222 to slide towards the front end of the diversion cylinder 221 through the connecting rod 243, pressing the emulsion into the homogenizing stirring tank 3 through the discharge conduit 25. After filling is completed, the piston 222 resets, preparing for the next cycle.

The lifting member 21 is two electric push rods, which are respectively arranged on opposite sides of the mounting plate 22. During the stage of extracting the emulsion, the forward and reverse motor 241 of the driving member 24 is started, driving the threaded lead screw 242 to rotate, making the slider 244 move backward, pulling the piston 222 to slide backward in the drainage cylinder 221 through the connecting rod 243 to form a negative pressure.
