Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid reaction kettles, in particular to a solid-liquid reaction kettle system with cooling and heating functions. Background Technique

[0002] In the field of chemical industry, solid-liquid reaction kettles are one of the key equipment for various chemical reactions, and are widely used in many industries such as pharmaceuticals, chemicals, and new material synthesis. Traditional solid-liquid reaction kettles often only have a single heating function, and the temperature of the reaction system is increased by means of electric heating, steam heating, or heat transfer oil heating to promote the progress of chemical reactions. However, with the progress of science and technology and the increase in the complexity of chemical reactions, a single heating function is no longer sufficient to meet the needs of modern chemical production.

[0003] First of all, the chemical reaction process is often accompanied by significant temperature changes, and some reactions can achieve the best reaction efficiency only within a specific temperature range. Traditional reaction kettles lack precise temperature control capabilities and are difficult to quickly adjust and stably maintain the temperature during the reaction process, resulting in low reaction efficiency and unstable product quality.

[0004] Secondly, for some chemical reactions that require a low-temperature environment or need to control exothermic reactions, traditional reaction kettles lack an effective cooling mechanism. During the reaction process, if the excess heat cannot be removed in time, it may lead to too high a reaction temperature, triggering side reactions or safety hazards. In addition, some reactants may decompose or deteriorate at high temperatures, further affecting the purity and yield of the product. Content of the Utility Model

[0035] One of the above technical solutions has the following beneficial effects:

[0036] When it is necessary to increase the reaction temperature in the stirring cavity of the reactor body, the electric heating tubes are energized and heated in the heat preservation cavity, and the heat is transferred to the solid-liquid mixture in the stirring cavity through the wall surface of the reactor body to achieve heating. Moreover, the design of the heat preservation jacket reduces the heat loss and improves the heating efficiency. At the same time, the thermometer installed through the jacket temperature measuring port monitors the temperature in the heat preservation cavity in real time to ensure that the heating process is carried out within the preset temperature range.

[0037] When it is necessary to reduce the reaction temperature in the stirring cavity of the reactor body or maintain a low-temperature environment, the cooling water enters the heat preservation cavity through the cooling water inlet. After the circulating action of the cooling mechanism, it absorbs the heat transferred out of the stirring cavity and then discharges from the cooling water outlet. Similarly, the thermometer monitors the temperature during the cooling process through the jacket temperature measuring port to ensure that the cooling effect meets the process requirements. The specific cooling process is as follows: When it is necessary to cool the reactor body, the cooling water delivery pump is started, and the cooling water in the heat preservation cavity of the heat preservation jacket is pumped out through the first cooling water delivery pipe. After the flow rate is controlled by the cooling water delivery solenoid valve, it is sent into the cooling water tank at the starting end, and then enters the next series-connected cooling water tank to further enhance the cooling effect. For the cooling water tanks that are not at the starting end, the cooling water in them is transported to the cooling tower for cooling through the second cooling water delivery pipe after reaching a certain temperature. The cooling tower uses natural wind or mechanical ventilation to make the water exchange heat with the air, thereby reducing the temperature of the cooling water. The cooling tower then sends the cooling water back to the heat preservation cavity through the third cooling water delivery pipe through the cooling water inlet. After absorbing the heat generated by the reaction in the stirring cavity, the temperature rises, and then it flows out through the cooling water outlet, forming a closed-loop cycle, reducing the waste of cooling water.

[0038] In summary, through the combined use of the electric heating tubes and the cooling mechanism, an efficient heating and cooling mechanism is integrated for the solid-liquid reactor, realizing precise control and rapid adjustment of the reaction temperature. Whether it is the heating or cooling process, it can ensure that the reaction is carried out under the optimal temperature conditions, improving the reaction efficiency and product quality.

For example, it may be a fixed connection, a detachable connection or an integral connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0046] A solid-liquid reaction kettle system with cooling and heating functions, comprising a reaction kettle body 1. A stirring cavity 10 is formed inside the reaction kettle body 1. A heat preservation jacket 2 is sleeved outside the reaction kettle body 1. A heat preservation cavity 20 is provided between the heat preservation jacket 2 and the reaction kettle body 1. An electric heating tube 3 attached to the outer wall surface of the reaction kettle body 1 is provided in the heat preservation cavity 20. A cooling water inlet 21, a cooling water outlet 22 and a jacket temperature measuring port 23 are opened on the heat preservation jacket 2. The cooling water inlet 21, the cooling water outlet 22 and the jacket temperature measuring port 23 are all communicated with the heat preservation cavity 20. A cooling mechanism is provided between the cooling water inlet 21 and the cooling water outlet 22. The jacket temperature measuring port 23 is used for installing a thermometer;

[0047] The cooling mechanism includes a cooling water tower 41 and a plurality of cooling water tanks 42 that are connected in sequence;

[0048] At the lower end of the cooling water tank 42 located at the starting end, a first cooling water delivery pipe 43 connected to the cooling water outlet 22 is provided, and a cooling water delivery pump 44 and a cooling water delivery solenoid valve 45 are provided on the first cooling water delivery pipe 43;

[0049] At the upper end of one of the cooling water tanks 42 that is not located at the starting end, a second cooling water delivery pipe 46 connected to the cooling water tower 41 is provided;

[0050] A third cooling water delivery pipe 47 is provided between the cooling water tower 41 and the cooling water inlet 21.

[0051] As Figures 1-3 shown, when it is necessary to increase the reaction temperature in the stirring cavity 10 of the reactor body 1, the electric heating tube 3 is energized and heated in the heat preservation cavity 20, and the heat is transferred to the solid-liquid mixture in the stirring cavity 10 through the wall surface of the reactor body 1 to achieve heating. Moreover, the design of the heat preservation jacket 2 reduces the heat dissipation and improves the heating efficiency. At the same time, the temperature in the heat preservation cavity 20 is monitored in real time by the thermometer installed through the jacket temperature measuring port 23 to ensure that the heating process is carried out within the preset temperature range.

[0052] When it is necessary to lower the reaction temperature in the stirring cavity 10 of the reactor body 1 or maintain a low-temperature environment, the cooling water enters the heat preservation cavity 20 through the cooling water inlet 21, and after the cyclic action of the cooling mechanism, absorbs the heat transferred out of the stirring cavity 10 and then discharges from the cooling water outlet 22. Similarly, the thermometer monitors the temperature during the cooling process through the jacket temperature measuring port 23 to ensure that the cooling effect meets the process requirements. The specific cooling process is as follows: When it is necessary to cool the reactor body 1, the cooling water delivery pump 44 is started, and the cooling water in the heat preservation cavity 20 of the heat preservation jacket 2 is pumped out through the first cooling water delivery pipe 43, and after the flow rate is controlled by the cooling water delivery solenoid valve 45, it is sent into the cooling water tank 42 at the starting end, and then enters the next series-connected cooling water tank 42 to further enhance the cooling effect. For the cooling water tank 42 that is not located at the starting end, the cooling water in it is transported to the cooling water tower 41 for cooling after reaching a certain temperature. The cooling water tower 41 uses natural wind or mechanical ventilation to make the water exchange heat with the air, thereby reducing the temperature of the cooling water. The cooling water tower 41 then returns the cooling water through the third cooling water delivery pipe 47 to the heat preservation cavity 20 through the cooling water inlet 21, absorbs the heat generated by the reaction in the stirring cavity 10, the temperature rises, and then flows out through the cooling water outlet 22, forming a closed-loop cycle, reducing the waste of cooling water.

[0053] In summary, the utility model integrates an efficient heating and cooling mechanism for the solid-liquid reactor through the combined use of the electric heating tube and the cooling mechanism, and realizes the precise control and rapid adjustment of the reaction temperature. Whether it is the heating or cooling process, it can ensure that the reaction is carried out under the optimal temperature conditions, thereby improving the reaction efficiency and product quality.

[0054] Further explanation, 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 feed port 54, and 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 feed port 54 and the discharge port 11 are all connected to the stirring cavity 10;

[0055] The powder inlet 51 is connected to a powder inlet mechanism via a powder inlet conveying pipe 60, the discharge port 11 is connected to a discharge mechanism via a discharge conveying pipe 70, and the feed port 54 is connected to a vacuum feed mechanism via a vacuum conveying pipe 90;

[0056] 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 .

[0057] Specifically, when feeding materials, not only can the solid reactants be accurately fed into the stirring cavity 10 of the reactor body 1 through the powder feeding mechanism connected between the powder feeding port 51 and the powder feeding conveying pipe 60, but also the liquid reactants can be accurately fed into the stirring cavity 10 of the reactor body 1 through the vacuum feeding mechanism connected between the feeding port 54 and the vacuum conveying pipe 90. This process ensures that the solid materials and liquid materials can be uniformly and quantitatively added to the reaction system, respectively, to prepare for the subsequent chemical reaction.

[0058] When the material is stirred, the stirring mechanism 8 extends into the stirring cavity 10 through the stirring port 52. After starting, the stirring mechanism 8 rotates in the stirring cavity to vigorously stir the solid-liquid mixture. This stirring action not only promotes the dispersion and dissolution of the solid reactant in the liquid, but also strengthens the contact and mixing between the reactants, thereby improving the rate and uniformity of the chemical reaction.

[0059] When the material reaction is completed and the material is discharged, the reaction product needs to be discharged through the discharge port 11 and the discharge conveying pipe 70 and the discharge mechanism connected thereto. This design makes the discharge and subsequent treatment of the reaction product more convenient, and also facilitates the cleaning and maintenance of the reactor.

[0060] To further illustrate, the vacuum feeding mechanism includes a vacuum buffer tank 91 and a vacuum pump 92;

[0061] The feed inlet 54 is connected to the vacuum buffer tank 91 and the vacuum pump 92 through the evacuation and conveying pipe 90, and a vacuum extraction solenoid valve 93 is provided on the evacuation and conveying pipe 90.

[0062] When vacuum treatment is required, first close other feeding and discharging valves or channels related to the stirring cavity 10 to ensure that the system is in a closed state. Open the vacuum extraction solenoid valve 93 to connect the evacuation and conveying pipe 90 to the vacuum pump 92 and the vacuum buffer tank 91. Start the vacuum pump 92 to extract the air or volatile substances in the stirring cavity 10 through the feed inlet 54, and enter the vacuum buffer tank 91 through the evacuation and conveying pipe 90 for preliminary buffering and collection.

[0063] When the reactor body 1 needs to feed inward, adjust the conveying direction of the vacuum pump 92 to suck the liquid reactant from the outside and send it into the stirring cavity 10 through the evacuation and conveying pipe 90 for reaction.

[0064] The vacuum pump 92 works repeatedly and continuously until the required vacuum degree is reached in the stirring cavity 10 and all the liquid reactants are extracted into the stirring cavity 10. At this time, the vacuum extraction solenoid valve 93 and the vacuum pump 92 can be closed according to needs to complete the process of vacuum extraction and feeding.

[0065] In summary, through the vacuum treatment of adding a vacuum feeding mechanism, impurities such as air and moisture in the stirring cavity 10 can be removed, reducing their interference and influence on the reaction process, thereby improving the reaction efficiency and product quality.

[0066] For further illustration, the powder feeding mechanism includes a powder feeding mounting frame 61, an electric hoist 62, an upper powder hopper 63 and a powder feeding hopper 64;

[0067] 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;

[0068] 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 stirred delivered by the upper powder hopper 63;

[0069] A powder feeding port is opened at the lower end of the powder feeding hopper 64, and a transverse auger 65, an inclined auger 66 and the powder feeding and conveying pipe 60 are sequentially connected to the powder feeding port. The transverse auger 65 is driven by a transverse auger motor 67, and the inclined auger 66 is driven by an inclined auger motor 68.

[0070] Specifically, the powder feeding mounting frame 61 serves as the support structure of the entire powder feeding mechanism, and the electric hoist 62 installed at its upper end plays a crucial role. When powder needs to be delivered, the electric hoist 62 is activated. Through its lifting and moving functions, the upper powder hopper 63 filled with the powder to be stirred is hoisted to a 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 into the lower powder feeding hopper 64. The powder feeding hopper 64 serves as a transition container, receiving and temporarily storing this powder to prepare for subsequent transportation. The powder feeding port at the lower end of the powder feeding hopper 64 is connected to a set of precise transportation systems, including a horizontal auger 65, an inclined auger 66, and a powder feeding pipeline 60. This system is driven by two independent motors - the horizontal auger motor 67 and the inclined auger motor 68. When receiving the delivery signal, the horizontal auger motor 67 is first activated, driving the horizontal auger 65 to rotate, and transporting the powder in the powder feeding hopper 64 along the horizontal direction to the inlet of the inclined auger 66. Subsequently, the inclined auger motor 68 is activated, driving the inclined auger 66 to rotate, continuously transporting the powder along the inclined direction, and finally feeding it into the stirring cavity 10 of the reactor body 1 through the powder feeding pipeline 60.

[0071] In summary, the powder feeding mechanism utilizes the hoisting and moving functions of the electric hoist 62, as well as the continuous transportation effects of the horizontal auger 65 and the inclined auger 66, to jointly achieve the efficient and accurate delivery of the powder to be stirred, improving production efficiency.

[0072] Furthermore, the inclination angle A of the inclined auger 66 is 30° - 60°.

[0073] Specifically, the selection of the inclination angle A of the inclined auger 66 is based on a comprehensive consideration of the material fluidity and transportation efficiency. Within this angle range, the powder can move more smoothly along the spiral blades of the inclined auger 66, reducing the possibility of blockage and stagnation, thereby improving the transportation efficiency.

[0074] Furthermore, the stirring mechanism 8 includes a paddle - type stirring component and a frame - type stirring component;

[0075] The paddle - type stirring component is located at the center of the stirring cavity 10. The paddle - type stirring component 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 the motor shaft of the reduction motor 811 is in transmission connection with the central rotating shaft 812. At least one paddle - type stirring blade 813 is provided on the central rotating shaft 812;

[0076] The frame-type stirring assembly is located around the stirring cavity 10, and the frame-type stirring assembly includes a frame body 821 arranged along the inner cavity wall of the stirring cavity 10, and a bottom scraper 822 is arranged on one side of the frame body 821 close to the inner cavity wall of the stirring cavity 10;

[0077] A groove 823 concave upward 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 via a bearing 824;

[0078] A connecting sleeve 825 is sleeved on the shaft body of the central rotating shaft 812 , and one end of a triangular support frame 826 is fixedly mounted on the outer surface of the connecting sleeve 825 , and the other end of the triangular support frame 826 is fixedly connected to the frame body 821 .

[0079] Specifically, the working principle of the paddle stirring assembly is as follows: the reduction motor 811 enters the stirring cavity 10 through the stirring port 52 provided on its motor shaft, and is connected to the central rotating shaft 812 by transmission. When the reduction motor 811 is started, it drives the central rotating shaft 812 to rotate. The paddle stirring blade 813 installed on the central rotating shaft 812 rotates with the shaft, and strongly stirs and mixes the material in the center of the stirring cavity 10. The design of the paddle stirring blade 813 can generate a large stirring force, which promotes the uniform dispersion of the material and the progress of the chemical reaction.

[0080] The working principle of the frame-type stirring assembly is as follows: the frame 821 of the frame-type stirring assembly is arranged along the inner cavity wall of the stirring cavity 10 to form a stirring frame surrounding the central rotating shaft 812. The bottom scraper 822 is installed on the side of the frame 821 close to the inner cavity wall to scrape off the material attached to the cavity wall to prevent the material from depositing and agglomerating. Furthermore, the 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 through a bearing 824. This connection method allows the frame 821 to rotate under the drive of the central rotating shaft 812 while maintaining a certain degree of freedom to adapt to the slight deformation during the stirring process. At the same time, the connecting sleeve 825 is sleeved on the shaft body of the central rotating shaft 812 and is fixedly connected to the frame 821 through 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 around the stirring cavity 10.

[0081] 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 .

[0082] Further explanation, the stirring mechanism 8 also includes two groups of dispersing stirring components, and the two groups of dispersing stirring components are located between the paddle stirring component and the frame stirring component;

[0083] The dispersion stirring assembly includes a dispersion motor 831 and a dispersion rotating shaft 832. The motor shaft of the dispersion motor 831 penetrates through the stirring port 52, and the motor shaft of the dispersion motor 831 is in transmission connection with the dispersion rotating shaft 832. At least one dispersion stirring disk 833 is provided on the dispersion rotating shaft 832.

[0084] Specifically, the motor shaft of the dispersion motor 831 passes through the stirring port 52 and enters the stirring cavity 10, and is in transmission connection with the dispersion rotating shaft 832. When the dispersion motor 831 is started, it drives the dispersion rotating shaft 832 to rotate. Moreover, at least one dispersion stirring disk 833 is installed on the dispersion rotating shaft 832, and these dispersion stirring disks 833 rotate with the dispersion rotating shaft 832 to shear, disperse and mix the materials passing near them.

[0085] In summary, the dispersion stirring assembly is located between the two, and the rotating dispersion stirring disks 833 further shear, disperse and mix the materials to ensure that the materials can fully contact and react during the stirring process.

[0086] Further explanation, the discharging mechanism includes a filter 71 and a liquid material pump 72 that are connected in sequence, and the filter 71 is connected to the discharging port 11 through the discharging conveying pipe 70.

[0087] When the solid-liquid reaction kettle needs to discharge materials, the solid-liquid mixture first enters the filter 71 through the discharging conveying pipe 70. The function of the filter 71 is to remove impurities in the raw materials, ensure the purity of the materials, and avoid adverse effects on the reaction process and product quality. The filtered materials then enter the liquid material pump 72, and the liquid material pump 72 provides power.

[0088] Further explanation, the discharging mechanism further includes a three-way valve 73;

[0089] 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 a circulation pipe 74 and a second discharging conveying pipe 75;

[0090] A circulation port 53 is also opened on the top cover 5, the circulation port 53 communicates with the stirring cavity 10, and the circulation port 53 is connected to the circulation pipe 74, and a circulation solenoid valve 76 is provided on the circulation pipe 74;

[0091] The discharging conveying pipe 70 and the second discharging conveying pipe 75 are used for discharging materials.

[0092] In order to enhance the mixing effect or control the reaction temperature during the reaction, it is sometimes necessary to circulate the material. At this time, the three-way valve 73 is adjusted to connect the output end of the liquid feed pump 72 with 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 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.

[0093] To further explain, the top cover 5 is also provided with an observation port 55 .

[0094] Specifically, the observation port 55 is opened on the top cover 5 so that it does not directly participate in the physical and chemical changes of the reaction process, but its existence is crucial for the operation, monitoring and maintenance of the solid-liquid reactor system. The main function of the observation port 55 is to allow the operator to directly observe the key parameters such as the reaction state, material mixing, and liquid level in the stirring cavity 10 without opening the reactor.

[0095] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementations of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
