The above-disclosed technology has the following problems: during the preparation of the suspension, operators need to observe the mixing state of the suspension, which not only wastes labor costs but also greatly reduces the production efficiency of suspension preparation. Existing technologies do not easily solve this problem. Therefore, there is an urgent need for a suspension preparation reaction device to solve the above problems. Summary of the Invention

[0010] Preferably, the stirring frame is provided with two symmetrical mixing chambers, a vertically arranged dispersing plate is fixed in the middle of the mixing chamber, and three arrayed flow divider plates are installed between the top and bottom of the mixing chamber. The three flow divider plates are deflected by a servo motor, which is installed inside the stirring frame.

[0011] Preferably, three vertically arrayed stirring blades are installed on one side of the mixing chamber, and a blade drive motor for driving the stirring blades is installed on the inner wall of the stirring frame. The blade drive motor and the three stirring blades are connected and powered by a bevel gear set.

[0012] Preferably, the mixing concentration detection module is used to detect the concentration of raw material mixture during the production and preparation of the suspension agent. The mixing concentration detection module also includes a motor speed detection sensor installed on the output shaft of the paddle drive motor, which is used to detect the rotation speed of the paddle drive motor and analyze the detection data of the motor speed detection sensor to generate a motor speed change coefficient F.

[0013] Preferably, a refractive index detection component is also provided at the middle position of the stirring frame. The refractive index detection component includes a detection cavity opened at the middle position of the stirring frame, and a sealing front cover is installed at both ends of the detection cavity.

[0020] Reference Figure 1 A suspension preparation reaction device includes a mixing component 100, which includes a preparation tank 101. The top of the preparation tank 101 is provided with a preparation hopper 102. The preparation tank 101 has an open structure design. During the preparation of a selected suspension, the proportioned suspension raw materials can be directly put into the preparation hopper 102 for mixing.

[0021] Reference Figure 1 , Figure 2 An adjustment assembly 200 is installed on the top of the mixing tank 101. The adjustment assembly 200 includes two fixed top brackets 201 installed on the top of the mixing tank 101. Both fixed top brackets 201 are installed vertically and are fixed in a symmetrical manner. The fixed top brackets 201 are fixed to the outer circumference of the mixing tank 101 by bolts. A horizontal crossbeam 202 is installed at the top of the two fixed top brackets 201. The height of the horizontal crossbeam 202 can be adjusted. A stirring assembly 300 for mixing the suspending agent is provided at the bottom of the horizontal crossbeam 202.

[0022] Reference Figure 2Both fixed top frames 201 have side sliding grooves 203 on their side walls. Slider blocks 204 are slidably installed in the side sliding grooves 203 of both fixed top frames 201. The sliders 204 can slide freely up and down within the side sliding grooves 203. The two ends of the horizontal crossbeam 202 are fixed to the sliders 204 at both ends. The sliders 204 are threadedly fixed to the horizontal crossbeam 202 by bolts. To adjust the height of the sliders 204, a vertically arranged lifting screw 207 is installed on the inner wall of the side sliding groove 203 via bearings. The lifting screw 207 is threadedly fitted to the slider 204. The forward and reverse rotation of the lifting screw 207 controls the lifting and lowering adjustment of the slider 204. An adjustment drive motor 205 is installed on the top of the fixed top frame 201. The output shaft of the adjustment drive motor 205 is connected and fixed to the top of the lifting screw 207. By controlling the rotation of the adjustment drive motor 205, the overall height of the slider 204 and the horizontal crossbeam 202 can be adjusted.

[0023] Reference Figures 1-3 A rotating stirring assembly 300 is provided at the bottom of the horizontal crossbeam 202. The stirring assembly 300 is used to mix and stir the raw materials during the production and preparation of the suspension agent, thereby improving the mixing efficiency of the suspension agent production. The stirring assembly 300 includes a vertically arranged stirring frame 301. The stirring frame 301 has two symmetrical mixing chambers. A vertically arranged dispersing plate 302 is fixed in the middle of the mixing chamber. Three arrayed flow divider plates 304 are installed between the top and bottom of the mixing chamber. The three flow divider plates 304 are deflected by a servo motor. The servo motor is installed inside the stirring frame 301. Three vertically arrayed stirring blades 303 are installed on one side of the mixing chamber. A blade drive motor for driving the stirring blades 303 is installed on the inner wall of the stirring frame 301. The blade drive motor and the three stirring blades 303 are connected and output through a bevel gear set.

[0024] Reference Figure 4 The dispersing plate 302 is in a vertical fixed state, and the dispersing plate 302 and the stirring frame 301 are designed as an integral structure. The side of the dispersing plate 302 away from the virtual axis is a beveled structure, and both sides of the dispersing plate 302 are beveled. When the stirring blade 303 conveys the suspending agent at the circumference of the mixing tank 101 into the virtual axis, the suspending agent can be dispersed to both sides, thereby improving the mixing efficiency of the suspending agent.

[0025] Reference Figure 2 , Figure 3 and Figure 4The flow divider plate 304 and the stirring frame 301 are connected by bearing matching. The deflection is controlled by the servo motor in the stirring frame 301. When the suspending agent is mixed, the servo motor controls the deflection of the flow divider plate 304, which can make the internal suspending agent more fully agitated and improve the efficiency of the suspending agent mixing reaction.

[0026] Reference Figures 1-4 A stirring drive motor 206 is fixed at the top center of the horizontal crossbeam 202. The output shaft of the stirring drive motor 206 extends to the bottom of the horizontal crossbeam 202. The top rotating shaft of the stirring frame 301 is rotatably installed between the horizontal crossbeam 202 and the top rotating shaft of the stirring drive motor 206 is fixedly connected to the top rotating shaft of the stirring frame 301. The rotation of the stirring drive motor 206 drives the rotation of the stirring frame 301, so that the suspension raw materials inside the mixing tank 101 are stirred, disturbed, and reacted.

[0027] The bottom of the mixing tank 101 is equipped with a control component, which includes a processor. The processor contains a refractive index detection module, a mixing concentration detection module, and a data processing module.

[0028] Furthermore, the mixing concentration detection module is used to detect the concentration of raw material mixture during the production and preparation of the suspension. The mixing concentration detection module also includes a motor speed detection sensor installed on the output shaft of the paddle drive motor, which is used to detect the rotational speed of the paddle drive motor and analyze the detection data of the motor speed detection sensor to generate the motor speed change coefficient F.

[0029] The control logic of the mixing concentration detection module is as follows: Since the production and preparation of the suspension requires the addition of raw materials and various mixtures, the final qualified suspension is generated through the reaction. At the beginning stage of suspension mixing, the concentration of raw materials is low, and the paddle drive motor outputs a constant output to make the stirring paddle 303 rotate stably. As the suspension preparation and reaction process progresses, the concentration of the suspension will change, causing the speed of the paddle drive motor to change. The speed of the paddle drive motor is detected in real time by the motor speed detection sensor.

[0030] In the early stage of suspension mixing, the concentration is low, and the speed of the paddle drive motor remains normal. Therefore, the motor speed variation coefficient F remains stable within a certain range. In the later stage of suspension mixing, the concentration increases, the speed of the paddle drive motor decreases, and the speed detection sensor detects the decrease in speed. As a result, the motor speed variation coefficient F gradually decreases. When the standard concentration of the suspension is reached, the motor speed variation coefficient F is maintained at a constant value.

[0031] Reference Figure 4A refractive index detection component 400 is also provided in the middle of the stirring frame 301. The refractive index detection component 400 includes a detection cavity 401 opened in the middle of the stirring frame 301. A sealing front cover 402 is installed at both ends of the detection cavity 401. A light refractive index detection sensor 403 is installed inside the sealing front cover 402. The sealing front cover 402 is made of transparent material, which allows the light beam of the light refractive index detection sensor 403 to pass through in parallel.

[0032] Refractive index detection module: used to acquire the detection data of optical refractive index detection sensor 403 in real time. Optical refractive index detection sensor 403 is used to detect the degree of solution mixing during the mixing process of the suspending agent, and analyzes the detection data of optical refractive index detection sensor 403 to generate the refractive index change coefficient T.

[0033] The control logic of the refractive index detection module is as follows: During the production of the suspending agent, the raw material and various mixing agents are added to form a final qualified suspending agent. At the beginning stage of suspending agent mixing, the concentration of the raw material is low, close to transparent, and the refractive index is high. As the mixing and formulation reaction process progresses, the concentration of the suspending agent increases and the refractive index decreases. The refractive index of the suspending agent is detected in real time by the optical refractive index detection sensor 403, and the refractive index change coefficient T is generated.

[0034] In the early stage of mixing the suspending agent, the concentration is low, the refractive index is high, and the coefficient of refractive index change T is relatively large. As the mixing and preparation reaction process progresses, the concentration increases, the refractive index decreases, and the coefficient of refractive index change T gradually decreases as the preparation reaction process progresses.

[0035] Data processing module: Used to collect the motor speed change coefficient F generated by the mixed concentration detection module and the refractive index change coefficient T generated by the refractive index detection module. The motor speed change coefficient F and the refractive index change coefficient T are weighted and summed to generate a decision coefficient S. The decision coefficient S is used to judge and analyze with the set threshold S1. Finally, the processor controls the status of the operation indicator light.

[0036] The weighted summation expression is:

[0037] in: F: represents the motor speed variation coefficient.

[0038] T: Represents the coefficient of refractive index variation.

[0039] : is the weight of the motor speed change coefficient.

[0040] : is the weight of the coefficient of refractive index change. The final processor compares and judges the obtained S and S1. If the indicator light turns red, it means the suspension preparation has not yet reached the standard. No further action is needed; continue preparing the suspension. This indicates that the mixing of the suspending agent has reached the preset standard, and the operation indicator light will turn green, indicating that the mixing reaction device can be shut down.

[0041] Operation indicator light = ; The above formulas are all dimensionless calculations. The formulas are derived from software simulations based on a large amount of collected data to obtain the most recent real-world results. The preset parameters in the formulas are set by those skilled in the art according to the actual situation.

[0042] In use of this invention: The operator puts the raw material for the suspension production and the mixture for the preparation reaction into the preparation tank 101, controls the preparation reaction device to start, and drives the stirring drive motor 206 to rotate the bottom stirring component 300 to carry out the mixing and preparation reaction of the suspension. By adjusting the rotation of the drive motor 205, the working position of the horizontal frame 202 and the bottom stirring component 300 is controlled. During the preparation reaction process, the processor's mixing concentration detection module and refractive index detection module detect the preparation reaction status of the suspension in real time through the motor speed detection sensor and the light refractive index detection sensor 403, respectively, and calculate the decision coefficient S through the data processing module. Finally, the processor compares the obtained S with S1 to make a judgment. If the indicator light turns red, it means the suspension preparation has not yet reached the standard. No further action is needed; continue preparing the suspension. This indicates that the mixing of the suspending agent has reached the preset standard, and the operation indicator light turns green, indicating that the mixing reaction device can be turned off. S1 is the set threshold, which is set according to the actual situation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
