Description

Technical Field

[0001] This utility model relates to the field of reaction vessels, and in particular to an automatic temperature-controlled reaction vessel for the production of chemical products. Background Technology

[0002] A reaction vessel is a comprehensive reaction container widely used in petroleum, chemical, rubber, pesticide, dye, and pharmaceutical industries. It can be used to complete various chemical reactions such as polymerization, condensation, sulfidation, alkylation, and hydrogenation. In the production of chemical products, different chemical reactions have strict requirements on conditions such as temperature, pressure, and time, and the reaction vessel needs to have corresponding performance and control functions to meet these requirements.

[0003] In chemical production, operators need to periodically check thermometer readings and manually adjust the power of heating or cooling equipment, valve openings, etc., to regulate the temperature inside the reactor. This method has several drawbacks. Firstly, manual monitoring is time-sensitive, making it difficult to accurately control temperature changes in real time, which can easily lead to excessive temperature fluctuations, affecting the quality and yield of chemical products. For example, in some temperature-sensitive polymerization reactions, temperature deviations can cause quality problems such as uneven polymer molecular weight distribution. Therefore, an automatic temperature-controlled reactor for chemical product production is proposed to solve these problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an automatic temperature-controlled reactor for chemical product production, aiming to improve the problem of internal temperature regulation in the reactor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic temperature-controlled reaction vessel for chemical product production, comprising a fixed plate, four support columns fixedly connected to the bottom of the fixed plate, a housing fixedly connected to the inner side of the fixed plate, a round cover slidably connected to the top of the housing, a water pump fixedly connected to the top of the fixed plate, an input pipe fixedly connected to the input end of the water pump, an output pipe fixedly connected to the output end of the water pump, a curved pipe fixedly connected to the end of the output pipe away from the water pump, both ends of the curved pipe penetrating the interior of the housing, a sealing plate slidably connected to the output end of the curved pipe, a cable fixedly connected to the side of the water pump away from the input pipe, a controller fixedly connected to the end of the cable away from the water pump, a conveying pipe provided on the side of the housing away from the water pump, a jacket fixedly connected to the interior of the housing, a discharge port opened at the bottom of the housing, and a valve fixedly connected to the bottom of the housing.

[0006] As a further description of the above technical solution: a bracket is fixedly connected to the top of the round cover, a motor is fixedly connected to the top of the bracket, a coupling is fixedly connected to the output end of the motor, a stirring shaft is fixedly connected to the bottom of the coupling, a shaft seal is fixedly connected to the top of the round cover, four agitators are fixedly connected to the middle of the stirring shaft, five scrapers are fixedly connected to the outer side of each of the four agitators, and an anti-clogging spiral is fixedly connected to the bottom of the stirring shaft.

[0007] As a further description of the above technical solution: the top of the box body is provided with a groove, and the bottom of the round cover is provided with a protrusion.

[0008] As a further description of the above technical solution: the conveying pipe penetrates the interior of the box body and the conveying pipe penetrates the interior of the jacket.

[0009] As a further description of the above technical solution: two handles are fixedly connected to the outer side of the round cover, and a handle is fixedly connected to the top of the sealing plate.

[0010] As a further description of the above technical solution: the end of the controller away from the cable is fixedly connected to the inside of the housing.

[0011] As a further description of the above technical solution: the stirring shaft penetrates the interior of the round cover, and the stirring shaft penetrates the interior of the shaft seal.

[0012] As a further description of the above technical solution: the side of the scraper away from the agitator is in contact with the inner side of the jacket.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the controller senses the temperature inside the chamber. When the temperature needs to be adjusted, the controller controls the water pump via a cable. The water pump draws the temperature control medium through the input pipe. The temperature control medium enters the curved pipe through the output pipe. The main body of the curved pipe is located inside the chamber. The temperature inside the reactor is changed through heat exchange. The medium inside the curved pipe can be adjusted by sliding the sealing plate, thus realizing the control of the temperature inside the reactor.

[0014] 2. In this utility model, during the material processing, the scraper fixed on the outside of the agitator will contact the inside of the jacket when it rotates.

Detailed Implementation

[0017] 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.

[0018] Reference Figures 1-4This utility model provides an embodiment of an automatic temperature-controlled reactor for chemical product production, comprising a fixed plate 1. Four support columns 2 are fixedly connected to the bottom of the fixed plate 1. The support columns 2 ensure the stability of the overall structure of the reactor and various internal production operations, laying the foundation for the safe and orderly conduct of the chemical product production process. A housing 3 is fixedly connected to the inner side of the fixed plate 1 to prevent the housing 3 from shaking or shifting, ensuring the integrity of the overall reactor structure and the reliability of the connections between components, creating conditions for the smooth operation of the chemical product production process. A round cover 4 is slidably connected to the top of the housing 3. This sliding connection facilitates the opening and closing of the round cover 4 relative to the housing 3. The round cover 4 can be easily slidable using a handle 5 on the outside, facilitating the feeding, maintenance, and cleaning of the reactor interior. A water pump 8 is fixedly connected to the top of the fixed plate 1. An input pipe 9 is fixedly connected to the input end of the water pump 8, and an output pipe 10 is fixedly connected to the output end of the water pump 8. A bent pipe 11 is fixedly connected to the end of the output pipe 10 away from the water pump 8. Both ends of the bent pipe 11 penetrate the interior of the chamber 3. A sealing plate 12 is slidably connected to the output end of the bent pipe 11. A cable 15 is fixedly connected to the side of the water pump 8 away from the input pipe 9. A controller 14 is fixedly connected to the end of the cable 15 away from the water pump 8. The controller 14 senses the temperature inside the chamber 3. When the temperature needs to be adjusted, the controller 14 controls the water pump 8 through the cable 15. The water pump 8 draws the temperature control medium through the input pipe 9. The temperature control medium enters the bent pipe 11 through the output pipe 10. The main body of the bent pipe 11 is coiled inside the chamber 3. The temperature inside the reactor is changed through heat exchange. The medium inside the bent pipe 11 can be adjusted by sliding the sealing plate 12, thus realizing the control of the temperature inside the reactor. A material conveying pipe 6 is installed on the side of the tank 3 away from the water pump 8. The material conveying pipe 6 runs through the interior of the tank 3 and the jacket 16, ensuring that the material can be accurately delivered to the reaction area inside the tank 3. This avoids leakage or failure to reach the predetermined reaction position during material conveying, allowing for precise and orderly material feeding in chemical production and laying the foundation for the smooth progress of subsequent reactions. The jacket 16 is fixedly connected inside the tank 3. It works in conjunction with the temperature control system consisting of the water pump 8 and the curved pipe 11. When the temperature control medium (such as hot or cold water) delivered by the water pump 8 circulates in the jacket 16, the jacket 16 acts as a heat transfer medium, evenly transferring heat to the material inside the tank 3 or removing heat from the material inside the tank 3. This achieves precise and stable control of the reaction temperature, meeting the strict requirements for reaction temperature in the production of different chemical products, helping to improve product quality and ensure that the reaction proceeds at the expected rate and effect. The bottom of the box 3 is provided with a discharge port, and a valve 24 is fixedly connected to the bottom of the box 3. The discharge port is located at the bottom of the box 3, which conforms to the physical characteristics of the material flowing out naturally by gravity, so that the material can be smoothly discharged from the reactor after the reaction is completed.Valve 24 is fixedly connected to the discharge port. Operators can flexibly adjust the discharge speed and flow rate by controlling the opening and closing degree of valve 24. For example, the discharge situation can be precisely controlled according to factors such as the feeding speed requirements of subsequent process links and the load-bearing capacity of material conveying pipelines, so as to ensure the continuity and coordination of the entire chemical production process.

[0019] Reference Figure 2 , Figure 4 A bracket 7 is fixedly connected to the top of the round cover 4. The bracket 7 provides a stable mounting base for the motor 17. During operation, the motor 17 will generate vibration and a certain force. By fixing it to the round cover 4 through the bracket 7, the motor 17 can be ensured to be in a suitable position and operate stably. This avoids the motor 17 shaking during operation from affecting the reliability of the connection between it and the stirring shaft 19 via the coupling 18. This ensures that the entire stirring system can smoothly and continuously stir the materials in the reactor. A shaft seal 20 is fixedly connected to the top of the round cover 4. The shaft seal 20 can play a good sealing role when the stirring shaft 19 rotates, preventing the materials in the reactor from leaking into the external environment. This avoids material waste and potential safety hazards and environmental pollution caused by material leakage. At the same time, it can also prevent external impurities from entering the reactor and affecting the quality of chemical products. A motor 17 is fixedly connected to the top of the support 7. A coupling 18 is fixedly connected to the output end of the motor 17. A stirring shaft 19 is fixedly connected to the bottom of the coupling 18. Four agitators 21 are fixedly connected to the middle of the stirring shaft 19. The motor 17 serves as the power source, stably driving the stirring shaft 19 to rotate through the coupling 18. This ensures that the stirring shaft 19 can rotate continuously and stably, providing reliable power support for subsequent material stirring. This allows the materials in the reactor to be fully stirred, facilitating thorough mixing and improving the uniformity and efficiency of the reaction. The four agitators 21 fixed in the middle of the stirring shaft 19 can stir the materials from different positions when the stirring shaft 19 rotates, expanding the stirring range and further enhancing the overall stirring effect. This avoids dead zones in the stirring process, ensuring that the materials are mixed relatively evenly throughout the reactor and that the chemical reaction proceeds uniformly in all parts of the material. Five scrapers 22 are fixedly connected to the outer side of each of the four agitators 21, and an anti-clogging spiral 23 is fixedly connected to the bottom of the stirring shaft 19.

[0020] Reference Figure 2 , Figure 4The top of the housing 3 has a groove, and the bottom of the round cover 4 has a protrusion. When the round cover 4 is installed in place, the protrusion is embedded in the groove, so that the connection between the round cover 4 and the housing 3 also has a certain limiting effect in the horizontal direction. During the operation of the reactor, even if it is affected by external forces such as the impact of materials during stirring and equipment vibration, the round cover 4 is not easy to shift or shake, ensuring the stability of the entire reactor structure. This is conducive to the stable operation of various functions such as stirring and temperature control, extending the service life of the equipment. At the same time, it forms a relatively tight connection structure, effectively filling any gaps that may exist between the two, preventing materials from leaking out from the top of the reactor, ensuring the safety of the production environment, and preventing material waste and environmental pollution problems that may be caused by leakage.

[0021] Reference Figure 2 The conveying pipe 6 penetrates the interior of the housing 3 and the jacket 16, ensuring that the material is accurately conveyed to the core reaction area of ​​the reactor, avoiding leakage or incomplete delivery during the conveying process, and ensuring that the material enters the predetermined reaction environment, which helps the subsequent reaction to proceed smoothly according to the predetermined process and conditions.

[0022] Reference Figure 1 , Figure 3 Two handles 5 are fixedly connected to the outer side of the round cover 4. During the chemical production process, it is necessary to regularly inspect, clean, maintain, or add materials to the reactor. By holding handles 5, the round cover 4 can be slid open along the top of the box 3 with relatively little effort. After the operation is completed, the round cover 4 can be easily closed with the help of handles 5, ensuring the sealing of the reactor and allowing the reaction to proceed normally in a relatively closed environment. A handle 13 is fixedly connected to the top of the sealing plate 12. The curved tube 11 plays an important role in conveying the temperature control medium in the temperature control system. The sealing plate 12 at its output end may wear out due to long-term use and need to be cleaned or replaced. Handle 13 facilitates the operation of the operator to perform corresponding maintenance and repair work on the end of the curved tube 11, ensuring the normal operation of the temperature control medium conveying link, and thus ensuring the temperature control effect of the entire reactor.

[0023] Reference Figures 1-3 The end of the controller 14 away from the cable 15 is fixedly connected inside the housing 3. It accurately controls the operation of the water pump 8 based on the real-time temperature of the material inside the reactor, including adjusting parameters such as the start / stop and flow rate of the water pump 8. This ensures the rationality of the circulation of the temperature control medium in the jacket 16, thereby achieving precise control of the reaction temperature and enabling the entire temperature control system to operate efficiently and accurately in coordination with the reaction process.

[0024] Reference Figure 2 , Figure 4The stirring shaft 19 penetrates the interior of the round cover 4 and the shaft seal 20. The shaft seal 20 can fit tightly against the stirring shaft 19, effectively filling the gap between the stirring shaft 19 and the round cover 4, preventing the materials and gases inside the reactor from leaking into the external environment. At the same time, it can also prevent external impurities and air from entering the reactor, ensuring a relatively independent and stable reaction environment inside the reactor, and ensuring that the reaction can proceed smoothly as expected.

[0025] Reference Figure 4 The side of scraper 22 furthest from agitator 21 contacts the inner side of jacket 16. During chemical production, materials may adhere to the inner wall of jacket 16 for various reasons (such as viscosity or flowability during agitation). With scraper 22 in contact with the inner side of jacket 16, as agitator shaft 19 drives agitator 21 and scraper 22 to rotate together, scraper 22 can scrape off the material adhering to the inner wall of jacket 16, allowing it to return to the main material in the reactor to participate in the reaction. This prevents material from accumulating on the inner wall of jacket 16 for a long time, thus ensuring the accuracy of the material quantity in the reactor and the normal progress of the reaction.

[0026] Working Principle: Materials are conveyed into the tank 3 through the conveying pipe 6, which penetrates both the tank 3 and the jacket 16, ensuring accurate entry of materials into the core reaction area of ​​the reactor. The reactor's round cover 4, with its bottom protrusion engaging with a groove on the top of the tank 3, achieves good sealing and positioning. The handle 5 on the outside of the round cover 4 facilitates opening and closing. After the motor 17 starts, its output drives the stirring shaft 19 to rotate via the coupling 18. The stirring shaft 19 penetrates both the round cover 4 and the shaft seal 20, ensuring a tight seal during rotation. Four agitators 21 fixed in the middle of the stirring shaft 19 rotate with it, mixing the materials inside the tank 3 to ensure thorough contact and reaction. Simultaneously, scrapers 22 fixed to the outside of the agitators 21 contact the inside of the jacket 16 during rotation, preventing material accumulation on the inner wall of the jacket 16 and ensuring cleanliness and uniform mixing inside the reactor. Water pump 8 draws a temperature-controlled medium, such as hot or cold water, through input pipe 9, and then delivers it to jacket 16 via output pipe 10 and curved pipe 11. Jacket 16 surrounds the interior of chamber 3. As the temperature-controlled medium flows within jacket 16, it regulates the temperature of the materials inside chamber 3 through heat transfer, thus controlling the reaction temperature. The sealing plate 12 at the output end of curved pipe 11 can be opened as needed via handle 13, for example, during maintenance or replacement, to release the temperature-controlled medium inside curved pipe 11. Furthermore, controller 14, connected by cable 15, is installed inside chamber 3 and can control water pump 8 and related equipment. For example, it can control the start and stop of water pump 8 based on set temperature parameters, thereby precisely regulating the flow rate and temperature of the temperature-controlled medium in jacket 16 to achieve accurate temperature control. Once the reaction is complete, open the valve 24 at the discharge port at the bottom of the tank 3, and the material can be discharged from the discharge port. The anti-clogging spiral 23 at the bottom of the stirring shaft 19 can prevent the material from clogging at the discharge port and other parts, thus completing the entire chemical product production process in the reactor.
