Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid reactors, in particular to a reactor system for solid-liquid mixing. Background Art

[0002] In today's chemical production, solid-liquid mixing reactions are a critical step in many chemical processes. Traditional reactor systems for solid-liquid mixing often utilize a single inlet to introduce both solid and liquid reactants. While this design simplifies the equipment structure, it presents numerous drawbacks in practical applications.

[0003] First, due to the distinct physical properties of solid and liquid reactants, mixing them at the same delivery port can easily lead to blockage. The accumulation and precipitation of solid particles can clog the delivery pipes, preventing the reactants from flowing smoothly into the reactor, thus affecting the continuity and stability of the entire production process. Furthermore, blockages increase equipment maintenance complexity and downtime, reducing production efficiency.

[0004] Secondly, sharing the same delivery port for both solid and liquid reactants also introduces operational complexity. During the dosing process, operators need to precisely control the ratio and rate of dosing of the two reactants to ensure uniform mixing within the reactor. However, due to the limitations of the delivery port, this precise control becomes particularly difficult, often requiring repeated adjustments based on manual experience. This not only increases labor intensity but also makes it difficult to ensure stability and consistency in each reaction. Utility Model Content

[0020] Preferably, the stirring mechanism includes a paddle stirring assembly and a frame stirring assembly;

[0021] The paddle stirring assembly is located at the center of the stirring cavity, and the paddle stirring assembly includes a reduction motor and a central rotating shaft. The motor shaft of the reduction motor passes through the stirring port, and the motor shaft of the reduction motor is in driving connection with the central rotating shaft. At least one paddle stirring blade is provided on the central rotating shaft.

[0022] The frame-type stirring assembly is located around the stirring cavity. The frame-type stirring assembly includes a frame body arranged along the inner cavity wall of the stirring cavity. A bottom scraper is provided on one side of the frame body close to the inner cavity wall of the stirring cavity.

[0023] Preferably, an upwardly concave groove is provided at the bottom of the frame near the discharge port, and the groove is connected to the lower end of the central rotating shaft through a bearing;

[0031] When liquid reactants and solid reactants are mixed and stirred, the stirring mechanism extends into the stirring cavity through the stirring port.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means two or more.

[0040] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0041] A reactor system for solid-liquid mixing includes a reactor body 1, wherein a stirring cavity 10 is formed inside the reactor body 1; a top cover 5 is installed at the upper end of the reactor body 1, and the top cover 5 is provided with a powder inlet 51, a stirring port 52, and a liquid inlet 54; a discharge port 11 is provided at the lower end of the reactor body 1, and the powder inlet 51, the stirring port 52, the liquid inlet 54, and the discharge port 11 are all connected to the stirring cavity 10;

[0042] The powder inlet 51 is connected to a powder feeding mechanism via a powder feeding conveying pipe 60, the discharge port 11 is connected to a discharge mechanism via a discharge conveying pipe 70, and the liquid inlet 54 is connected to an external liquid conveying mechanism;

[0043] A stirring mechanism 8 is installed above the top cover 5 via a crossbeam 80 , and the stirring mechanism 8 extends into the stirring cavity 10 of the reactor body 1 through the stirring port 52 .

[0044] like Figure 1-3 As shown, when liquid reactants are fed, they are transported by the discharge mechanism to the stirring cavity 10 of the reactor body 1 through the discharge port 11 and the discharge delivery pipe 70 connected thereto.

[0045] When solid reactants are fed, the powder feeding mechanism connected to the powder feeding port 51 and the powder feeding conveying pipe 60 can accurately feed the solid reactants into the stirring cavity 10 of the reactor body 1 .

[0046] When liquid reactants are fed, the liquid reactants can be accurately fed into the stirring cavity 10 of the reactor body 1 by connecting the liquid inlet 54 to an external liquid delivery mechanism.

[0047] These two processes ensure that solid materials and liquid materials can be added to the reaction system evenly and quantitatively, preparing for subsequent chemical reactions.

[0048] When the liquid reactants and solid reactants are mixed and stirred, the stirring mechanism 8 extends into the stirring cavity 10 through the stirring port 52. After activation, the stirring mechanism 8 rotates within the stirring cavity, vigorously stirring the solid-liquid mixture. This stirring action not only promotes the dispersion and dissolution of the solid reactants in the liquid, but also strengthens the contact and mixing between the reactants, thereby improving the rate and uniformity of the chemical reaction.

[0049] After the reaction is completed, the reaction product is discharged from the reactor body 1 by the discharge mechanism through the discharge port 11 and the discharge conveying pipe 70 connected thereto.

[0050] In summary, the utility model designs the conveying systems of solid reactants and liquid reactants separately, which not only makes the addition of solids and liquids and the discharge of reaction products more convenient and efficient, reducing the labor intensity of operators, but also effectively avoids the blockage problem caused by the mixed conveying of the two, thereby improving the continuity and stability of the production process.

[0051] To further illustrate, the powder feeding mechanism includes a powder feeding mounting frame 61, an electric hoist 62, a powder loading hopper 63 and a powder throwing hopper 64;

[0052] The electric hoist 62 is installed at the upper end of the powder feeding mounting frame 61, and the electric hoist 62 is used to lift and move the upper powder hopper 63 to a preset position;

[0053] The powder feeding hopper 64 is installed at the lower end of the powder feeding mounting frame 61, and the powder feeding hopper 64 is used to receive the powder to be mixed fed by the upper powder hopper 63;

[0054] A powder feeding port is provided at the lower end of the powder feeding hopper 64 , and the powder feeding port is equipped with a horizontal dragon 65 , an oblique dragon 66 and the powder feeding conveying pipe 60 which are connected in sequence. The horizontal dragon 65 is driven by a horizontal dragon motor 67 , and the oblique dragon 66 is driven by an oblique dragon motor 68 .

[0055] Specifically, the powder feeding mounting frame 61 serves as the supporting structure of the entire powder feeding mechanism, and the electric hoist 62 installed on its upper end plays a key role. When powder needs to be delivered, the electric hoist 62 is started, and through its lifting and moving functions, the upper powder hopper 63 containing the powder to be mixed is hoisted to the preset position. This step ensures that the powder can be accurately and stably placed above the powder feeding hopper 64. After reaching the preset position, the powder in the upper powder hopper 63 is delivered to the powder feeding hopper 64 below. The powder feeding hopper 64 serves as a transition container, receiving and temporarily storing these powders in preparation for subsequent transportation. The powder feeding port at the lower end of the powder feeding hopper 64 is connected to a sophisticated conveying system, including a horizontal dragon 65, an oblique dragon 66 and a powder feeding conveying pipe 60. This system is driven by two independent motors - the horizontal dragon motor 67 and the oblique dragon motor 68. When the delivery signal is received, the horizontal dragon motor 67 starts first, driving the horizontal dragon 65 to rotate, conveying the powder in the powder hopper 64 in the horizontal direction to the entrance of the oblique dragon 66. Subsequently, the oblique dragon motor 68 starts, driving the oblique dragon 66 to rotate, continuing to convey the powder in the oblique direction, and finally delivering it into the stirring cavity 10 of the reactor body 1 through the powder inlet conveying pipe 60.

[0056] In summary, the powder feeding mechanism utilizes the lifting and moving functions of the electric hoist 62 and the continuous conveying function of the horizontal dragon 65 and the oblique dragon 66 to achieve efficient and accurate delivery of the powder to be mixed, thereby improving production efficiency.

[0057] To further illustrate, the angle A of the oblique dragon 66 is between 30° and 60°. Specifically, the angle A of the oblique dragon 66 is selected based on a comprehensive consideration of material flowability and conveying efficiency. Within this angle range, the powder can move more smoothly along the spiral blades of the oblique dragon 66, reducing the possibility of blockage and stagnation, thereby improving conveying efficiency.

[0058] To further explain, the discharging mechanism includes a filter 71 and a liquid pump 72 which are connected in sequence, and the filter 71 is connected to the discharge port 11 through the discharging conveying pipe 70.

[0059] When the solid-liquid reactor needs to discharge material, the solid-liquid mixture first enters filter 71 through discharge pipe 70. Filter 71 removes impurities from the raw materials, ensuring their purity and preventing adverse effects on the reaction process and product quality. The filtered material then enters liquid pump 72, which provides power.

[0060] To further illustrate, the discharging mechanism further includes a three-way valve 73;

[0061] One end of the three-way valve 73 is connected to the liquid material pump 72, and the other two ends of the three-way valve 73 are respectively connected to the circulation pipe 74 and the second discharge conveying pipe 75;

[0062] The top cover 5 is further provided with a circulation port 53 , which is connected to the stirring cavity 10 , and is also connected to the circulation pipe 74 , which is provided with a circulation solenoid valve 76 ;

[0063] The discharge conveying pipe 70 and the second discharge conveying pipe 75 are used for discharging materials.

[0064] During the reaction process, in order to enhance the mixing effect or control the reaction temperature, it is sometimes necessary to circulate the material. In this case, the three-way valve 73 is adjusted so that the output end of the liquid pump 72 is connected to the circulation pipe 74, so that the feeding and discharging of materials and the material circulation can be flexibly switched, meeting the needs of different reaction processes and improving the versatility and operational flexibility of the equipment. The material can enter the circulation port 53 of the stirring cavity 10 through the circulation pipe 74 and participate in the stirring and reaction again. In addition, the circulation solenoid valve 76 on the circulation pipe 74 is used to control the opening and closing of the circulation process.

[0065] To further illustrate, the stirring mechanism 8 includes a paddle stirring assembly and a frame stirring assembly;

[0066] The paddle stirring assembly is located at the center of the stirring cavity 10 and includes a reduction motor 811 and a central rotating shaft 812. The motor shaft of the reduction motor 811 passes through the stirring port 52 and is in transmission connection with the central rotating shaft 812. The central rotating shaft 812 is provided with at least one paddle stirring blade 813.

[0067] The frame-type stirring assembly is located around the stirring cavity 10 and includes a frame body 821 arranged along the inner wall of the stirring cavity 10 . A bottom scraper 822 is provided on one side of the frame body 821 close to the inner wall of the stirring cavity 10 .

[0068] Specifically, the paddle stirring assembly operates as follows: a reduction motor 811 passes through the stirring port 52 on its motor shaft and enters the stirring cavity 10, where it is connected to the central rotating shaft 812. When the reduction motor 811 is started, it drives the central rotating shaft 812 to rotate. The paddle stirring blades 813 mounted on the central rotating shaft 812 rotate with the shaft, vigorously stirring and mixing the material in the center of the stirring cavity 10. The design of the paddle stirring blades 813 can generate a large stirring force, promoting the uniform dispersion of the material and the progress of the chemical reaction.

[0069] The frame-type stirring assembly operates as follows: The frame 821 of the frame-type stirring assembly is positioned along the inner wall of the stirring cavity 10, forming a stirring frame surrounding the central rotating shaft 812. A bottom scraper 822 is mounted on the side of the frame 821 near the inner wall to scrape away material adhering to the cavity wall and prevent material deposition and agglomeration.

[0070] To further illustrate, an upwardly concave groove 823 is provided at the bottom of the frame 821 near the discharge port 11, and the groove 823 is connected to the lower end of the central rotating shaft 812 through a bearing 824;

[0071] A connecting sleeve 825 is sleeved on the shaft of the central rotating shaft 812 . One end of a triangular support frame 826 is fixedly mounted on the outer surface of the connecting sleeve 825 . The other end of the triangular support frame 826 is fixedly connected to the frame 821 .

[0072] Furthermore, a groove 823 at the bottom of the frame 821, near the discharge port 11, is connected to the lower end of the central rotating shaft 812 via a bearing 824. This connection allows the frame 821 to rotate driven by the central rotating shaft 812 while maintaining a certain degree of freedom to accommodate minor deformations during the stirring process. Simultaneously, a connecting sleeve 825 is sleeved onto the shaft of the central rotating shaft 812 and fixedly connected to the frame 821 via a triangular support frame 826. This structural design enhances the stability of the frame 821, enabling it to more effectively stir and mix the materials surrounding the stirring cavity 10.

[0073] In summary, the design of the stirring mechanism 8 combines a paddle-type stirring component and a frame-type stirring component to achieve comprehensive and uniform mixing of the materials in the stirring cavity 10 .

[0074] To further illustrate, the stirring mechanism 8 further includes two sets of dispersing stirring components, both of which are located between the paddle stirring component and the frame stirring component;

[0075] The dispersion stirring assembly includes a dispersion motor 831 and a dispersion rotating shaft 832. The motor shaft of the dispersion motor 831 passes through the stirring port 52 and is transmission-connected to the dispersion rotating shaft 832. At least one dispersion stirring disk 833 is provided on the dispersion rotating shaft 832.

[0076] Specifically, the motor shaft of the dispersion motor 831 passes through the stirring port 52 and enters the stirring cavity 10, where it is in transmission connection with the dispersion rotating shaft 832. When the dispersion motor 831 is activated, it drives the dispersion rotating shaft 832 to rotate. Furthermore, at least one dispersion stirring disk 833 is mounted on the dispersion rotating shaft 832. These dispersion stirring disks 833 rotate with the dispersion rotating shaft 832, shearing, dispersing, and mixing the materials passing therethrough.

[0077] In summary, the dispersing and stirring component is located between the two, and further shears, disperses and mixes the materials through its rotating dispersing and stirring disk 833, ensuring that the materials can fully contact and react during the stirring process.

[0078] To further explain, the outer sleeve of the reactor body 1 is provided with an insulation jacket 2, and an insulation cavity 20 is provided between the insulation jacket 2 and the reactor body 1. The insulation cavity 20 is provided with an electric heating tube 3 attached to the outer wall of the reactor body 1, and a jacket temperature measuring port 21 is opened on the insulation jacket 2. The jacket temperature measuring port 21 is connected to the insulation cavity 20, and the jacket temperature measuring port 21 is used to install a thermometer.

[0079] When the reaction temperature of the stirring cavity 10 within the reactor body 1 needs to be increased, the electric heating tube 3 is energized within the insulation cavity 20 to generate heat. Heat is transferred to the solid-liquid mixture within the stirring cavity 10 through the wall of the reactor body 1, thereby heating the mixture. Furthermore, the design of the insulation jacket 2 reduces heat loss and improves heating efficiency. Simultaneously, a thermometer installed through the jacket temperature measuring port 21 monitors the temperature within the insulation cavity 20 in real time, ensuring that the heating process is carried out within the preset temperature range.

[0080] To further explain, the top cover 5 is further provided with an observation port 55 .

[0081] Specifically, observation port 55 is provided on top cover 5 so that it does not directly participate in the physical and chemical changes during the reaction process. However, its presence is crucial for the operation, monitoring, and maintenance of the solid-liquid reactor system. The primary function of observation port 55 is to allow the operator to directly observe key parameters such as the reaction state, material mixing, and liquid level within stirring cavity 10 without opening the reactor.

[0082] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific embodiments of the present invention without inventive effort, and such equivalent variations or substitutions are encompassed within the scope of the claims of this application.
