AI Technical Summary
Traditional reactors suffer from uneven mixing, long reaction induction periods, and the formation of mixing blind zones when mixing materials with high viscosity or large density differences. This is especially true in the synthesis of nanoparticles and the reaction of high-viscosity polymers, where it is difficult to suppress particle agglomeration and material residue.
A multifunctional glass reactor was designed, employing a multi-directional stirring mechanism, including a motor-driven transmission sleeve, slide bar, limiting bar, sphere, and inclined annular rail, to achieve the helical three-dimensional motion of the stirring frame. Combined with a real-time monitoring system using a micro pump and an industrial camera, it realizes convection, shearing, and diffusion effects, ensuring uniform mixing of materials and dynamic monitoring of the reaction process.
It enables rapid mixing of materials with high viscosity and large density differences, shortens mixing time, avoids mixing blind spots, and improves reaction efficiency and product quality, making it suitable for rapid reactions and parameter-sensitive experiments.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, specifically a multifunctional glass reaction vessel. Background Technology
[0002] In experiments and production in fields such as chemistry, biology, and materials, glass reactors, due to their high light transmittance, corrosion resistance, and good chemical stability, have become core equipment for realizing visualized reactions, material mixing, and process development. Traditional reactors often employ a single rotary stirring mechanism (such as paddle or anchor stirrers), which can only provide planar shear force. For high-viscosity materials, liquid-solid suspensions, or multiphase materials with large density differences, "mixing blind zones" are easily formed at the bottom or surface of the vessel, leading to insufficient material dispersion, long reaction induction periods, and even side reactions caused by excessively high local concentrations. For example, in nanoparticle synthesis, traditional stirring is insufficient to suppress particle agglomeration, resulting in uneven particle size distribution; in high-viscosity polymer reactions, material remains at the bottom of the vessel due to ineffective agitation, causing raw material waste and product quality fluctuations. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides a multi-functional glass reactor, which has the advantage of stirring materials from multiple directions, thus solving the problem of uneven mixing of materials caused by a single rotary stirring mechanism.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0005] A multifunctional glass reactor includes a body containing a tank with a glass cover. The body has a mixing mechanism and a monitoring mechanism for detecting reactants. The mixing mechanism includes a motor with a transmission sleeve fixed to its output end. A slide rod is slidably connected inside the transmission sleeve. A groove is formed on the outside of the transmission sleeve. A limit strip is fixed to the slide rod, extending to the outside of the groove and fixed to a ball. An inclined annular rail is provided outside the transmission sleeve, and the ball is slidably connected to the annular rail. A stirring rack is fixed to the bottom of the slide rod, located inside the tank.
[0006] Preferably, the monitoring mechanism includes a micro pump fixed to the outside of the machine body, the port of the micro pump is connected to a connecting pipe, the end of the connecting pipe is inserted into the inside of the tank, a material box is fixed to the outside of the machine body, the micro pump introduces the reactants in the tank into the material box, and an industrial camera for detecting the reactants in the material box is fixed to the machine body.
[0007] Preferably, a discharge pipe is fixedly connected to the bottom of the material box, an electric valve is installed on the discharge pipe, and a waste bin is placed below the discharge pipe.
[0008] Preferably, an electric heating tube is fixed to the outside of the tank, and the electric heating tube is spiral-shaped.
[0009] Preferably, the transmission sleeve is connected to the glass cover via a bearing, and an electric telescopic rod is also fixedly mounted on the machine body. The free end of the electric telescopic rod is fixedly connected to a bracket, and the motor is fixedly mounted on the bracket.
[0010] Preferably, a solution tank is placed on the outside of the machine body, a pump body is installed on the solution tank, a guide pipe is fixedly connected to the port of the pump body, the other end of the pump body is connected to the inside of the solution tank through a pipe, and the end of the guide pipe extends into the tank body.
[0011] By employing the above technical solution, this utility model provides a multifunctional glass reactor, which has at least the following beneficial effects:
[0012] 1. This multi-functional glass reactor can agitate materials from different directions when mixing them, so that the stirring rack forms a spiral trajectory inside the tank (with both circular motion and up-and-down reciprocating motion). This three-dimensional motion can simultaneously apply shearing, convection and diffusion effects to the materials in the radial, axial and circumferential directions, which can greatly shorten the mixing time. It is especially suitable for materials with high viscosity and large density differences.
[0013] 2. This multifunctional glass reactor can draw reaction liquid into the material box at regular intervals or continuously to realize real-time dynamic monitoring of the reaction process. It is especially suitable for scenarios that require high-frequency observation (such as rapid reaction or parameter-sensitive experiments). Compared with direct observation of the inside of the tank, sampling and detection is more convenient for capturing subtle changes (such as initial precipitation or the generation of trace bubbles).

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] The following describes some embodiments of the multifunctional glass reactor provided by this utility model with reference to the accompanying drawings.
[0025] Example 1:
[0026] Unidirectional stirring, when used with materials containing particles, powders, or easily sedimenting substances, makes it difficult for bottom sediments to rise to the upper layer to participate in the reaction. This can easily lead to material accumulation, excessively high local concentrations, and even side reactions or impaired heat transfer efficiency. To address these issues, a combination of... Figures 1-3 As shown, the multifunctional glass reactor provided by this utility model includes a body 100, a tank 101 placed inside the body 100, and a glass cover 102 installed on the tank 101. The glass cover 102 has high light transmittance, allowing experimenters to observe the liquid state inside the tank in real time (such as color changes, bubble generation, and sediment formation). It is especially suitable for scenarios that require dynamic monitoring of the reaction process. The body 100 is equipped with a mixing mechanism 200, which is conducive to the mixing of various materials. Through the mechanical stirring of the stirring paddle, the liquid is circulated and flowed, so that materials of different densities and viscosities are quickly dispersed, shortening the time of "layering → uniform mixing". The body 100 is also equipped with a monitoring mechanism 300 for detecting reactants. The stirring speed, heating / cooling rate, and feeding sequence are adjusted according to real-time data to keep the reaction always within the optimal parameter range, reduce the generation of by-products, and improve the yield and purity.
[0027] The mixing mechanism 200 includes a motor 201. A transmission sleeve 202 is fixedly connected to the output end of the motor 201. A slide rod 203 is slidably connected inside the transmission sleeve 202. A groove 209 is formed on the outer side of the transmission sleeve 202. A limiting strip 204 is fixedly connected to the slide rod 203. The limiting strip 204 extends to the outside of the groove 209 and is fixedly connected to a ball 205. An inclined annular rail 206 is provided outside the transmission sleeve 202. The ball 205 is slidably connected to the annular rail 206. A stirring rack 207 is fixedly connected to the bottom of the slide rod 203. The stirring rack 207 is located inside the tank 101. When the motor 201 is started, it drives the transmission sleeve 202 to rotate. The transmission sleeve 202 drives the slide rod 203 to rotate. The stirring rack 207 rotates with the slide rod 203, thereby enabling the mixing mechanism to... The material inside the tank 101 is stirred, and the ball 205 on the slide bar 203 moves along the inclined annular rail 206. Due to the inclined annular rail 206, the ball 205 moves from top to bottom and then from bottom to top. Subsequently, the slide bar 203 also moves up and down with the ball 205, causing the stirring rack 207 to move up and down. Thus, when mixing materials, the materials are stirred in different directions, and the stirring rack 207 forms a spiral trajectory inside the tank 101 (with both circular motion and up-and-down reciprocating motion). This three-dimensional motion can simultaneously apply shearing, convection and diffusion effects to the materials in the radial, axial and circumferential directions, greatly shortening the mixing time. It is especially suitable for materials with high viscosity and large density differences.
[0028] Specifically, an electric heating tube 208 is fixed to the outside of the tank 101. The electric heating tube 208 is spiral-shaped and can heat the material inside the tank 101.
[0029] Furthermore, the transmission sleeve 202 is connected to the glass cover 102 via a bearing. An electric telescopic rod 103 is also fixedly mounted on the machine body 100. A bracket is fixedly connected to the free end of the electric telescopic rod 103. The motor 201 is fixedly mounted on the bracket. When the electric telescopic rod 103 extends and retracts, it can drive the bracket to move up and down. The glass cover 102 below also moves with the bracket. After the reaction is completed, it is convenient to clean the inside of the tank 101.
[0030] A solution tank 104 is placed on the outside of the body 100. A pump body is installed on the solution tank 104. A guide pipe is fixed to the port of the pump body. The other end of the pump body is connected to the inside of the solution tank 104 through a pipe. The end of the guide pipe extends into the tank body 101. When the pump body is started, the liquid inside the solution tank 104 can be injected into the tank body 101 for reaction.
[0031] As can be seen from the embodiments, the up-and-down movement of the stirring rack 207 can cover the entire height range of the tank 101 (from the liquid surface to the bottom of the tank), avoiding the formation of a mixing blind zone near the bottom or liquid surface by the traditional fixed-height stirring paddle. Especially for sedimentary materials (such as systems containing particles and powders), it can continuously lift the bottom sediments to the upper layer to participate in mixing and prevent material accumulation.
[0032] Example 2:
[0033] Visual inspection can only capture surface features such as color and bubbles, and cannot quantitatively analyze key parameters such as turbidity and particle size distribution. Furthermore, it is easily affected by fluid movement in a dynamically stirred environment, leading to judgment errors. To address these issues, a new approach is developed that combines... Figure 2 and Figure 4 As shown, based on Embodiment 1, the monitoring mechanism 300 includes a micro pump 301 fixed to the outside of the body 100. A connecting pipe 302 is installed at the port of the micro pump 301, and the end of the connecting pipe 302 is inserted into the tank 101. A material box 303 is fixed to the outside of the body 100. The micro pump 301 introduces the reactants from the tank 101 into the material box 303. An industrial camera 304 for detecting the reactants in the material box 303 is fixed to the body 100. The micro pump 301 injects the reacted material from the tank 101 into the material box 303 through the connecting pipe 302. Subsequently, the industrial camera 304 detects the material, and the camera transmits the image to an industrial control computer with a built-in high-performance GPU via a GigE / USB 3.0 interface. It runs color space conversion algorithms (such as RGB to HSV to extract hue features), edge detection algorithms (Canny operator to identify bubble outlines), and particle analysis algorithms (based on watershed algorithm to count the number and size distribution of sediment particles). The system pre-calibrates lens distortion using a checkerboard calibration plate and establishes color concentration mapping relationships using a standard colorimetric card to ensure the geometric accuracy and physical quantity accuracy of the detection data. When a sudden change in material turbidity is detected (such as exceeding a preset threshold to trigger a sedimentation warning) or an abnormal bubble generation frequency (such as a sudden increase in the number of bubbles per unit time indicating a violent reaction), the industrial control computer sends a signal to the PLC via the Modbus protocol to adjust the sampling frequency of the micro pump 301 or trigger the adaptive adjustment of the stirring rate of the tank 101.
[0034] Specifically, a discharge pipe is fixed to the bottom of the material box 303, an electric valve 305 is installed on the discharge pipe, and a waste bin 306 is placed below the discharge pipe. After a single test is completed, the electric valve 305 opens and the material in the material box 303 is introduced into the waste bin 306 below.
[0035] As can be seen from the above embodiments: In the pre-reaction preparation stage, the required liquid for the reaction is injected into the tank 101 via a guide pipe through the pump on the solution tank 104, and the material is added through the opening of the glass cover 102. The electric telescopic rod 103 is activated to adjust the height of the support, ensuring a sealed connection between the glass cover 102 and the tank 101, and confirming that the stirring rack 207 is in the initial position in the middle of the tank 101. The spiral electric heating tube 208 is activated as needed to preheat the tank 101 to uniformly heat the material. In the reaction stage, the motor 201 is activated to drive the transmission sleeve 202 to rotate. The upper limit bar 204 of the slide rod 203 moves along the outer sliding groove 209 of the transmission sleeve 202. The ball 205 slides spirally within the inclined annular rail 206, driving the slide rod 203 and the stirring rack 207 to perform a three-dimensional motion of "rotation + up-and-down reciprocating motion," applying radial shear and axial shear to the material throughout the entire height range of the tank 101 in a spiral trajectory. The reaction proceeds rapidly through convection and circumferential diffusion to disperse multiphase materials and prevent sedimentation. Subsequently, the micro pump 301 is activated, drawing the reactants from the tank through the connecting pipe 302 and injecting them into the material box 303 on the outside of the machine body 100. The industrial camera 304 captures images of the materials in the material box 303, identifying features such as color changes, turbidity, sedimentation state, and bubble formation. Combined with a preset algorithm model, the system judges the reaction progress or abnormal state. If parameters need to be adjusted, the system controls the speed of the motor 201, the power of the heating element 208, or the pump feeding rate to maintain the reaction in an optimal state. After the reaction is completed, the motor 201 and the heating element 208 are stopped, and the electric telescopic rod 103 is activated to raise the support. The glass cover 102 moves with the support and detaches from the tank body 101, exposing the tank body 101 for manual or automatic cleaning.
