Description

Technical Field

[0001] The utility model belongs to the technical field of reactors, and in particular relates to a reactor cooling structure. Background Art

[0002] During chemical reactions, the reactor's cooling system is crucial for ensuring temperature control. Traditional reactor designs often lack effective sealing technology between the lid and the reactor body.

However, existing technologies still have shortcomings in ensuring the tightness of the connection between the reactor cover and the reactor body. This is particularly true under high-temperature, high-pressure, and frequently vibrating operating conditions, where the stability of the reactor cover remains difficult to ensure.

DETAILED DESCRIPTION

[0050] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0051] In the description of this application, it should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship. Technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, technologies, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0052] Example 1:

[0053] like Figure 1 and Figure 2 As shown, this embodiment provides a reactor cooling structure, comprising:

[0054] A kettle body 1 is provided with a kettle cover 2;

[0055] The liquid inlet pipe 3 is arranged on the top of the kettle cover 2 and is connected to the kettle body 1;

[0056] The liquid outlet pipe 4 is arranged at the bottom of the kettle body 1;

[0057] Connecting legs 5 are provided on both sides of the kettle body 1;

[0058] The cooling mechanism 7 is provided outside the kettle body 1 and is used to cool the reactants in the kettle body 1;

[0059] The reinforcement mechanism 6 is provided between the kettle body 1 and the kettle cover 2 and is used to fix the kettle cover 2 on the kettle body 1 to prevent leakage of the reactants;

[0060] The reinforcement mechanism 6 includes:

[0061] The clamping plates 61 are arranged on the left and right sides of the kettle cover 2;

[0062] The card slot 62 is provided on the card plate 61;

[0063] The fixing blocks 63 are arranged at both ends of the outer side of the upper part of the kettle body 1;

[0064] A guide rod 64 is provided on the fixed block 63;

[0065] The locking plate 65 is slidably disposed on the guide rod 64 and is engaged with the card slot 62 of the card plate 61;

[0066] Push plate 66, provided on the lower side of locking plate 65;

[0067] The return spring 67 is sleeved on the guide rod 64 and disposed between the locking plate 65 and the kettle body 1 .

[0068] In the present technical solution, by means of a cooling mechanism 7 arranged on the outside of the kettle body 1, the cooling medium can effectively reduce the temperature of the reactants inside the reactor, ensure that the reaction is carried out at an appropriate temperature, and prevent safety problems caused by excessively high temperatures. The reinforcement mechanism 6 ensures a tight connection between the kettle cover 2 and the kettle body 1, and can effectively prevent leakage of reactants, especially in the presence of vibration or high pressure, thereby improving the safety of the reactor. The reinforcement mechanism 6 enables the kettle cover 2 to be quickly and firmly locked on the kettle body 1 through the coordinated action of the card plate 61, the card slot 62, the guide rod 64 and the locking plate 65, making it easy to install and disassemble and reducing the difficulty of operation. The design of the reset spring 67 enables the locking mechanism to automatically return to its position when released, which facilitates the re-fixation of the kettle cover 2 and increases the service life of the device.

[0069] Workflow: The operator places the kettle cover 2 on the top of the kettle body 1. The slot 62 on the card plate 61 docks with the locking plate 65 on the guide rod 64, allowing the locking plate 65 to slide along the guide rod 64 and squeeze the reset spring 67. When the card plate 61 stops moving, under the action of the reset spring 67, the locking plate 65 moves in the opposite direction along the guide rod 64, causing the locking plate 65 to move and engage with the slot 62, thereby fixing the kettle cover 2 and ensuring that the kettle cover 2 is firmly fixed to the kettle body 1. Then the reaction can be carried out. During the reaction, the reinforcement mechanism 6 always keeps the kettle cover 2 tightly connected to the kettle body 1 to prevent leakage of reactants. The kettle cover 2 and the kettle body 1 provide stable support. Then the cooling mechanism 7 is started. The cooling mechanism 7 takes away the heat inside the kettle body 1 through the flow of coolant, ensuring that the reactants are maintained within the required temperature range. When the reaction is complete or maintenance of the kettle body 1 is required, the operator only needs to release the push plate 66, and the locking plate 65 can slide upward along the guide rod 64 and disengage the locking groove 62 on the locking plate 61. At this time, due to the action of the return spring 67, the locking plate 65 will automatically reset, allowing the kettle cover 2 to be easily removed. After the kettle body 1 and the kettle cover 2 are separated, it is convenient to clean, maintain or replace the reactants in the kettle. When the locking plate 65 is released, the spring can quickly return to its original position, ensuring the flexibility and reusability of the device. This achieves a tight connection between the kettle cover 2 and the kettle body 1, avoiding leakage problems caused by vibration or internal pressure changes, making the installation and removal of the kettle cover 2 simpler and more efficient. At the same time, the cooling mechanism 7 effectively controls the temperature inside the reactor, providing a guarantee for the stable progress of the reaction.

[0070] Example 2:

[0071] This embodiment provides a reactor cooling structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0072] like Figure 1-Figure 3 As shown, in this embodiment, the cooling mechanism 7 is optimized to include:

[0073] The cooling medium channel 71 is provided on the outer wall of the kettle body 1;

[0074] a liquid storage tank 72 , located below the cooling medium channel 71 ;

[0075] The water inlet end of the water pump 73 is connected to the liquid storage tank 72 , and the water outlet end of the water pump 73 is connected to the cooling medium channel 71 .

[0076] In this technical solution, the design of the cooling medium channel 71 enables the cooling medium to flow evenly on the outer wall of the reactor, increases the heat exchange area, and thus efficiently takes away the heat generated in the reaction process. Through the circulation system of the water pump 73, the flow of the cooling medium can be flexibly adjusted to ensure that the temperature in the reactor remains within the required range. The setting of the liquid storage tank 72 provides a stable source of cooling medium for the cooling system, ensuring that under different reaction conditions, the supply of coolant is always sufficient. The use of the water pump 73 enables the cooling process to be automated, reduces the complexity of manual operation, and improves the safety and reliability of the system.

[0077] Workflow: The cooling medium (such as water or other coolant) is first stored in a liquid storage tank 72. The design of liquid storage tank 72 ensures that the amount of coolant is always sufficient during the operation of the cooling system. At the start of the reaction, the operator starts water pump 73. The water inlet of water pump 73 is connected to liquid storage tank 72. It is responsible for extracting the cooling medium from liquid storage tank 72 and sending it to cooling medium channel 71. The operation of water pump 73 enables the cooling medium to flow rapidly, providing continuous cooling for the reactor. Water pump 73 delivers the cooling medium to cooling medium channel 71 through the water outlet. Cooling medium channel 71 is set on the outer wall of the reactor, so that the coolant is in close contact with the reactor wall. Within the channel, the cooling medium flows along the designed path and is evenly distributed around the kettle body 1, forming a good heat exchange. During the chemical reaction, the heat generated by the reactants is absorbed by the cooling medium. The cooling medium removes the heat from the reactor through convection and conduction during flow, thereby preventing the reactants from overheating and ensuring a stable reaction temperature. The cooled medium flows out through the upper end of the cooling medium channel 71 and can flow back to the liquid storage tank 72, forming a closed cooling cycle system. This circulation process ensures that the cooling medium can be continuously recycled, thereby effectively reducing cooling costs and reducing the impact on the environment. The circulating flow of the cooling medium not only improves the safety of the reaction process, but also promotes the efficient conduct of the reaction. This can meet the cooling needs under various reaction conditions and provide a stable environment for chemical reactions.

[0078] like Figure 2 and Figure 3 As shown, in this embodiment, the cooling medium channel 71 is optimized to be spiral-shaped and extends along the outer wall of the kettle body 1 .

[0079] In this technical solution, the operator first ensures that there is sufficient cooling medium in the liquid storage tank 72. After starting the water pump 73, the cooling medium is pumped through the water outlet of the water pump 73 and transported to the inlet of the spiral cooling medium channel 71. After entering the spiral channel, the cooling medium begins to flow along the channel. Due to the spiral design of the channel, the cooling medium continuously contacts the outer wall of the kettle body 1 during the flow process, forming an effective heat exchange. During the reaction process, the reactants in the kettle body 1 release a large amount of heat. The design of the spiral channel ensures a large contact area between the cooling medium and the kettle body 1, allowing the cooling medium to effectively absorb this heat and reduce the temperature of the kettle body 1. The cooled medium flows out through the outlet of the spiral channel. Before flowing out, the cooling medium has already removed the heat from the kettle body 1, reducing the temperature of the kettle body 1. The cooled medium returns to the liquid storage tank 72 through the outlet pipe, forming a closed cooling circulation system. The channel design not only increases the flow path length but also promotes heat exchange. The number and compactness of the spiral channels can generally be optimized based on the diameter and height of the reactor to ensure fluid flow efficiency and cooling effect. The flow of fluid in the spiral channel is affected by centrifugal force and viscosity. The fluid can be better mixed and heat exchanged in the channel, reducing turbulence and dead zone phenomena, which is beneficial to improving the cooling effect. The design of the spiral cooling medium channel 71 significantly improves the cooling effect and heat exchange efficiency. The cooling medium flows evenly through the spiral channel, enhancing the absorption of heat in the reactor.

[0080] Example 3:

[0081] This embodiment provides a reactor cooling structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0082] like Figure 1 and Figure 3 As shown, in this embodiment, it is optimized that a heat-insulating shell 8 is provided on the outside of the kettle body 1 , and the cooling medium channel 71 is located inside the heat-insulating shell 8 .

[0083] In the present technical scheme, insulation shell 8 can effectively reduce the heat that reactor produces during operation and loses to external environment, keeps reactant within the required temperature range, and improves heat energy utilization efficiency. Cooling medium channel 71 is arranged inside insulation shell 8, and the heat insulation characteristics of insulation shell 8 can be utilized so that cooling medium keeps lower temperature during flow, strengthens its cooling effect on reactor. By reducing the temperature of reactor outer surface, avoid the potential safety hazard caused by high temperature, especially in the process of high temperature reaction or violent reaction, insulation shell 8 can effectively protect operating personnel and surrounding equipment. Insulation shell 8 can provide additional protection, prevents external environmental factors (such as wind, cold air etc.) from interfering with reaction process, ensures the stability of reaction conditions. By arranging insulation shell 8 outside kettle body 1, and cooling medium channel 71 is placed in insulation shell 8 inside, effectively improves cooling efficiency and heat energy utilization rate in reaction process, insulation shell 8 can reduce heat loss, improves safety, and the design of cooling medium channel 71 ensures the flow of cooling liquid and the efficient carrying out of heat exchange.

[0084] like Figure 1 、 Figure 3 and Figure 4 As shown, in this embodiment, it is optimized that air cooling mechanisms 9 are provided on both sides of the heat preservation shell 8, and the air cooling mechanisms 9 include:

[0085] The air guide tube 91 is provided on both sides of the heat-insulating shell 8 and passes through the heat-insulating shell 8;

[0086] The mounting shell 92 is disposed inside the air guide tube 91;

[0087] The electric fan 93 is provided in the mounting shell 92 and introduces air from the air duct 91 into the interior of the heat-insulating shell 8;

[0088] The filter screens 94 are disposed on both sides of the mounting housing 92 and are located at the air inlet and air outlet of the electric fan 93 .

[0089] In this technical solution, external air is introduced into the interior of the insulation shell 8 by the action of the electric fan 93, and the convection effect of the air is utilized to accelerate the dissipation of heat and enhance the cooling effect. The air cooling mechanism can effectively reduce the temperature of the outer wall of the reactor and prevent safety hazards caused by high temperature. The setting of the filter 94 can effectively filter dust and impurities in the air and prevent these substances from entering the interior of the insulation shell 8, thereby maintaining the cooling effect and avoiding damage to the reactor and the cooling system. The design of the air cooling mechanism 9 can be used in conjunction with the liquid cooling system, and the intensity of the air cooling can be flexibly adjusted according to the heat changes during the reaction process to achieve more precise temperature control.

[0090] Working process: Start the electric fan 93. The electric fan 93 rotates to draw the outside air into the air duct 91. The air duct 91 effectively introduces the outside air into the insulation shell 8. Before entering the electric fan 93, the outside air will pass through the filter 94 set on both sides of the mounting shell 92. The function of the filter 94 is to filter dust and impurities in the air to ensure that only clean air enters the insulation shell 8, thereby protecting the internal components and the reactor. Once the air is introduced into the insulation shell 8, it exchanges heat with the environment inside the insulation shell 8, accelerates the air flow, enhances the heat transfer between the air and the outer wall of the reactor, and helps to reduce the surface temperature of the reactor body 1. As the outside air continues to flow in, the temperature inside the insulation shell 8 will gradually decrease. After the heated air undergoes heat exchange, its temperature rises and it is then discharged from the air duct 91 by the electric fan 93 to form an air circulation system. This process can be carried out continuously to ensure that the temperature of the outer wall of the reactor remains within a safe range. This not only enhances the cooling capacity, but also effectively promotes air flow and enhances heat dissipation. The combination of liquid cooling and air cooling provides a strong guarantee for the stable operation of the reactor under high temperature conditions, adapts to the needs of various industrial environments, and ensures a safe and efficient reaction process.

[0091] Example 4:

[0092] This embodiment provides a reactor cooling structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0093] like Figure 1 and Figure 5 As shown, in this embodiment, the optimization further includes a stirring mechanism 10, and the stirring mechanism 10 includes:

[0094] The support base 101 is provided on the kettle cover 2, and the support base 101 passes through the kettle cover 2;

[0095] The motor 102 is disposed inside the support base 101;

[0096] Flange 103, provided on the output shaft of motor 102;

[0097] The mounting plate 104 is mounted on the bottom of the flange 103 by means of bolt connection;

[0098] A stirring rod 105 is connected to the mounting plate 104;

[0099] A stirring head 106 is provided on the stirring rod 105;

[0100] There are multiple stirring blades 107 , which are arranged on the stirring head 106 along the circumferential direction.

[0101] In this technical solution, the stirring mechanism 10, through the action of the stirring rod 105 and the stirring blade 107, enables the materials in the reactor to be fully mixed, avoiding uneven reactions caused by precipitation or stratification, which is particularly important for chemical reactions that require uniform distribution of catalysts or reactants. By increasing the contact area of ​​the materials through stirring, the reaction rate can be accelerated. Especially in liquid reactions or solid-liquid reactions, the stirring effect can effectively improve the progress of the reaction. In gas-liquid reactions, stirring can effectively promote the generation of bubbles and the contact of liquids, thereby improving the solubility of the gas and the reaction efficiency.

[0102] Working process: Start the motor 102, and the rotation of the motor 102 drives the flange 103 to rotate. The flange 103 transmits power to the mounting plate 104 through a bolt connection. The rotation of the flange 103 will directly cause the rotation of the stirring rod 105, and the stirring rod 105 drives the stirring head 106 and the stirring blades 107 thereon to move together. The multiple stirring blades 107 on the stirring head 106 are arranged along the circumferential direction. The purpose of this design is to generate a certain flow and shear force during rotation, stirring the material in the kettle from the bottom to the top, and also pushing the material above down to form an effective material circulation, thereby ensuring that all materials in the reactor can be fully stirred, thereby achieving material uniformity, providing a more efficient and safer operating environment, and being suitable for use under different chemical reaction conditions.
