Description

Technical Field

[0001] The invention relates to the technical field of reboilers, and in particular to a reboiler with optimized protection and disassembly and assembly and a use method thereof. Background Art

[0002] In the prior art, the defect of reboilers is that many reboilers lack connection protection structures, and the connection points are directly exposed to the external environment. This makes the connection points vulnerable to erosion by fluids, chemicals or environmental factors (such as humid air, corrosive gases, etc.). The exposure of connection points increases the risk of accidents. For example, the connection may loosen due to external collisions, thereby causing fluid leakage. Once the leakage is flammable, explosive or toxic substances, it may cause serious accidents such as fire, explosion or poisoning under certain circumstances, posing a huge threat to the safety of personnel life and production facilities.

[0003] The horizontal reboiler disclosed in publication number CN203196367U has significant design defects. The equipment lacks a connection protection structure, which causes the connection point to be directly exposed to the external environment, increasing the risk of damage to the connection due to collision, corrosion or erosion by external chemicals. This not only shortens the service life of the equipment, but may also cause safety accidents due to leakage. The lack of a protective structure also causes significant heat loss, resulting in an increase in heating load and reducing the energy efficiency of the system. In addition, the design of the connection of the reboiler is not convenient for quick disassembly and assembly, and the repair and maintenance process requires a lot of time and manpower.

[0004] These problems seriously restrict the operational stability and economic benefits of the equipment and urgently need to be solved through optimized design. Summary of the invention

[0005] In order to overcome the defects of the above technologies, the purpose of the present invention is to provide a reboiler with optimized protection and disassembly and assembly and a method of use. The reboiler and the method of use have the characteristics of high-efficiency protection performance, excellent sealing, convenient disassembly and assembly mechanism, optimized fluid transmission performance and strong structural stability, which significantly improve the safety, energy efficiency and maintenance convenience of the equipment.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A reboiler with optimized protection and disassembly and assembly, comprising a reboiler body 17, wherein the reboiler body 17 is connected to a delivery pipe 14 through a connecting pipe 15, and a limiting groove 12 is respectively provided at the connection between the delivery pipe 14 and the connecting pipe 15;

[0008] A sealing strip 13 is provided between the limiting grooves 12 on both sides. The sealing strip 13 is an annular structure. A sealing disassembly mechanism is symmetrically provided along the outer side of the annular structure. The sealing disassembly mechanism is used to control the installation and disassembly of the sealing strip 13, the delivery pipe 14 and the connecting pipe 15.

[0009] The reboiler body 17 is used to form a stable heat exchange condition to ensure efficient heat transfer.

[0010] The seal disassembly mechanism includes a motor 3, which is arranged on the top of the fixed seat 2. The output shaft of the motor 3 passes through the inside of the shell 1 and is connected to a gear 4. The shell 1 is a square structure and is vertically arranged. Racks 5 are arranged on both sides of the inner side of the shell 1 in parallel. The racks 5 are respectively arranged on both sides of the gear 4, and the racks 5 are meshed with the gear 4. A connecting block 6 is arranged on the top of the rack 5 on one side, and a connecting block 6 is arranged on the bottom of the rack 5 on the other side. One side of the connecting block 6 extends to the outside of the shell 1 and is fixedly connected to a positioning plate 7. The upper positioning plate 7 and the opposite surface below are movably connected to two mounting blocks 18, and the mounting block 18 is installed at the end of the sealing strip 13.

[0011] The housing 1 is a rectangular parallelepiped structure, with through holes 10 respectively formed on the upper and lower sides. One side of the connecting block 6 extends to the outside of the through hole 10 , and the connecting block 6 is slidably connected to the inner wall of the through hole 10 .

[0012] The racks 5 are arranged one above and one below; the limiting plates 11 are fixedly connected to both sides of the housing 1, and the limiting plates 11 on both sides are arranged one above and one below, respectively, the bottom of the upper limiting plate 11 is connected to the lower rack 5, and the top of the lower limiting plate 11 is connected to the upper rack 5;

[0013] The surface of the limiting plate 11 is slidably connected to the rack 5 .

[0014] The surface of the motor 3 is sleeved with a mounting seat 9, the bottom of the mounting seat 9 is fixedly connected to the fixing seat 2, and the four corners of the bottom of the reboiler body 17 are fixedly connected with support plates 16, and the support plates 16 are symmetrically arranged.

[0015] The surfaces of the opposite sides of the positioning plate 7 are fixedly connected with anti-skid pads 8 , and the surfaces of the anti-skid pads 8 are provided with longitudinal stripe textures.

[0016] The connection between the connecting pipe 15 and the reboiler body 17 adopts a variable diameter structure, and the pipe diameter on the side close to the reboiler body 17 is larger, and its diameter is set to 100mm; to meet the flow and pressure requirements of the fluid flowing out of the reboiler body 17, provide a relatively spacious channel for the fluid, reduce the local resistance of the fluid when flowing out of the reboiler body 17, and enable the fluid to enter the connecting pipe 15 more smoothly. The pipe diameter on the side away from the reboiler body 17 is smaller, and the diameter is 80mm.

[0017] The variable diameter structure allows the fluid to gradually adjust the flow rate and pressure distribution in the process of flowing out of the reboiler body 17 and entering the connecting pipe 15, avoiding adverse flow phenomena such as eddy currents and turbulence caused by sudden changes in the pipe diameter. Eddy currents and turbulences will increase the energy loss of the fluid, reduce the fluid transportation efficiency, and may even cause damage such as erosion and corrosion to the pipeline. Through the transition of the variable diameter structure, the fluid can flow in the pipeline in a more stable and orderly state, reducing energy loss and improving the operating efficiency of the entire system.

[0018] The limiting groove 12 is annular and is arranged around the end of the connecting pipe 15 on one side opposite to the conveying pipe 14. This annular design can fully surround the circumference of the connecting part, ensuring that effective sealing and positioning functions can be provided in all directions.

[0019] The limiting groove 12 is tightly matched with the sealing strip 13, and the shape and size of the sealing strip 13 are adapted to the limiting groove 12, and can completely fill the space of the limiting groove 12 to form a reliable sealing interface. When the connecting pipe 15 is connected to the delivery pipe 14, the sealing strip 13 is squeezed in the limiting groove 12, so as to fit tightly to the surface of the connection part to prevent the passage of fluid or gas.

[0020] The delivery pipe 14 is a cylindrical pipe body, which has many advantages in fluid delivery. The cylindrical shape allows the fluid to be evenly distributed around the pipe wall when flowing in the pipe, reducing the local flow velocity difference and pressure change caused by the irregular shape.

[0021] The mounting block 18 is a rectangular parallelepiped structure, and is fixedly connected to both sides of the sealing strip 13 to form an integral component with the sealing strip 13. The connection method ensures that the mounting block 18 and the sealing strip 13 will not be relatively displaced during installation and use, thereby ensuring the integrity and stability of the sealing structure.

[0022] A method for using a reboiler with a connection protection structure comprises the following steps:

[0023] Step 1: Initial Sealing and Protection Stage

[0024] When the reboiler starts working, the connecting pipe 15 and the delivery pipe 14 are closely matched through the limiting groove 12 and the sealing strip 13 to form a reliable sealing connection; the limiting groove 12 is annular, with a depth of 5mm and a width of 10mm, and the sealing strip 13 is tightly embedded therein to effectively prevent fluid or gas leakage;

[0025] At this time, the fluid or gas is completely blocked by the sealing strip 13 at the connection between the connecting pipe 15 and the delivery pipe 14, ensuring the stability of the internal pressure of the system, maintaining the integrity and safety of the system, and reducing the risk of accidents caused by leakage; at the same time, the connection protection structure wraps the connection point to prevent the external environment from eroding the connection point, reducing the possibility of equipment failure and damage, and reducing the heat loss from the connection point to the surrounding environment, thereby improving energy efficiency;

[0026] Step 2: Disassembly preparation phase when repair or replacement of parts is required

[0027] The user starts the motor 3, and the output shaft of the motor 3 starts to rotate. The motor 3 can be a small and efficient motor with a power of [X] kilowatts, which is determined according to the actual equipment requirements. The output shaft speed can reach [Y] revolutions per minute, which is determined according to factors such as the gear ratio. The rotation of the output shaft of the motor 3 drives the gear 4 fixedly connected thereto to rotate. The gear 4 meshes with the racks 5 provided on both sides of the inner cavity of the housing 1. The module of the gear 4 is set to [M], which is determined according to the requirements of the transmitted torque, and the number of teeth is [Z], which is designed to cooperate with the rack 5. Through precise meshing transmission, the rotational motion of the motor 3 is converted into the linear motion of the rack 5.

[0028] Step 3: Connection and Release Phase

[0029] Driven by the gear 4, the rack 5 starts to move, and the connecting block 6 fixedly connected to one side of the rack 5 moves synchronously therewith. The connecting block 6 slides in the through hole 10 opened on one side of the shell 1. The through hole 10 has a diameter of 30 mm, which provides a stable sliding channel for the connecting block 6, ensuring that the moving direction of the connecting block 6 is accurate and stable; the movement of the connecting block 6 drives the positioning plates 7 to move toward each other, and the opposite sides of the positioning plates 7 are fixedly connected with anti-skid pads 8. The longitudinal striped texture provided on the surface of the anti-skid pads 8 increases the friction between the mounting block 18, ensuring accurate and stable positioning. As the positioning plates 7 move toward each other, the fixing effect of the positioning plates 7 on the mounting block 18 is gradually released, so that the connection between the connecting pipe 15 and the conveying pipe 14 is in a detachable state, which is convenient for the subsequent maintenance or replacement of components of the conveying pipe 14;

[0030] Step 4: Reinstallation phase after repair or replacement of parts is completed

[0031] When the repair or replacement of parts is completed, the delivery pipe 14 is reconnected with the connecting pipe 15, so that the sealing strip 13 is accurately embedded in the limiting groove 12, and the mounting block 18 is located at the initial action position of the positioning plate 7. Then the reverse control of the motor 3 can be realized by circuit design, the motor 3 drives the gear 4 to reverse, and then drives the rack 5 to move in the opposite direction, the connecting block 6 and the positioning plate 7 to move in the opposite direction, and the positioning plate 7 re-applies pressure to the mounting block 18, and the sealing strip 13 is pressed tightly into the limiting groove 12 again, so that the connecting pipe 15 and the delivery pipe 14 are reconnected tightly, ensuring that the equipment returns to normal operation. The whole process is easy to operate, effectively improving the maintenance efficiency and reducing the maintenance time.

[0032] Beneficial effects of the present invention:

[0033] The sealing strip of the present invention cooperates with the limiting groove: the annular limiting groove 12 arranged on the opposite side of the connecting pipe 15 and the conveying pipe 14 has a depth of 5mm and a width of 10mm, and two sealing strips 13 fit tightly inside. This structural design forms a reliable sealing interface at the connection point, effectively preventing fluid or gas leakage. In industrial scenarios such as chemical industry, if the reboiler processes toxic, flammable or corrosive fluids, leakage may cause serious safety accidents and environmental pollution, and the cooperation between the sealing strip 13 and the limiting groove 12 effectively avoids such risks, ensures the stability of the internal pressure of the system, and maintains the integrity and safety of the system.

[0034] Connection protection structure wraps the connection point: The entire connection protection structure wraps the connection point, providing an additional layer of protection for the connection part of the reboiler. It blocks the direct erosion of the connection point by dust, moisture, corrosive gases, etc. in the external environment. For example, in a humid or corrosive environment, the metal parts of the connection point without protection are prone to rust and corrosion, resulting in loose connection and reduced strength. The protection structure reduces the possibility of equipment failure and damage, thereby improving the safety of equipment operation.

[0035] The connection protection structure of the present invention is heat-insulated: the protection structure that wraps the connection point itself has certain heat-insulating properties, which reduces the heat loss from the connection point to the surrounding environment through conduction, convection and radiation. During the operation of the reboiler, heat loss not only reduces the energy utilization efficiency, but also may affect the vaporization effect and separation efficiency of the internal liquid mixture. Through the heat-insulating effect of the connection protection structure, the relative stability of the temperature field inside the equipment is maintained, so that more heat is used in the vaporization and separation process of the liquid mixture, thereby improving energy utilization efficiency and reducing the risk of performance degradation due to heat loss.

[0036] During actual use, the coordinated use of sealing strips and limit grooves can prevent problems such as leakage and corrosion and reduce the risk of accidents. The connection protection structure can wrap the connection point, prevent the direct impact of the external environment on the connection point, and provide an additional layer of protection to reduce the possibility of equipment failure and damage. It can reduce the loss of heat transmitted to the surrounding environment. Subsequently, through the coordinated use of the positioning mechanism, it can be easily disassembled and reinstalled, which makes the repair and maintenance of the reboiler easier, reduces maintenance time and cost, and solves the problem that the above-mentioned reboiler lacks a connection protection structure, which makes the connection point of the reboiler exposed to the external environment and increases the risk of accidents.

[0047] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0048] like Figure 1-Figure 8As shown, a reboiler with optimized protection and disassembly and assembly includes a reboiler body 17, the reboiler body 17 is connected to a delivery pipe 14 through a connecting pipe 15, and a limiting groove 12 is respectively provided at the connection between the delivery pipe 14 and the connecting pipe 15;

[0049] A sealing strip 13 is provided between the limiting grooves 12 on both sides. The sealing strip 13 is an annular structure. A sealing disassembly mechanism is symmetrically provided along the outer side of the annular structure. The sealing disassembly mechanism is used to control the installation and disassembly of the sealing strip 13, the delivery pipe 14 and the connecting pipe 15.

[0050] The reboiler body 17 is used to form a stable heat exchange condition to ensure efficient heat transfer.

[0051] The seal disassembly mechanism includes a motor 3, which is fixedly connected to the top of the fixing seat 2. The output shaft of the motor 3 passes through the housing 1 and is connected to a gear 4. Racks 5 are numerically arranged on both sides of the housing 1 in parallel. The racks 5 are respectively arranged on both sides of the gear 4, and the racks 5 are meshed with the gear 4. One side of the rack 5 is fixedly connected to a connecting block 6, one side of the connecting block 6 extends to the outside of the housing 1 and is fixedly connected to a positioning plate 7, and the opposite side of the positioning plate 7 is movably connected to two mounting blocks 18, and the mounting block 18 is installed at the end of the sealing strip 13.

[0052] The housing 1 is a rectangular parallelepiped structure, with through holes 10 respectively formed on the upper and lower sides. One side of the connecting block 6 extends to the outside of the through hole 10 , and the connecting block 6 is slidably connected to the inner wall of the through hole 10 .

[0053] The racks 5 are arranged one above and one below; the limiting plates 11 are fixedly connected to both sides of the housing 1, and the limiting plates 11 on both sides are arranged one above and one below, respectively, the bottom of the upper limiting plate 11 is connected to the lower rack 5, and the top of the lower limiting plate 11 is connected to the upper rack 5;

[0054] The surface of the limiting plate 11 is slidably connected to the rack 5 .

[0055] The surface of the motor 3 is sleeved with a mounting seat 9, the bottom of the mounting seat 9 is fixedly connected to the fixing seat 2, and the four corners of the bottom of the reboiler body 17 are fixedly connected with support plates 16, and the support plates 16 are symmetrically arranged.

[0056] The surfaces of the opposite sides of the positioning plate 7 are fixedly connected with anti-skid pads 8 , and the surfaces of the anti-skid pads 8 are provided with longitudinal stripe textures.

[0057] The connection between the connecting pipe 15 and the reboiler body 17 adopts a variable diameter structure, and the pipe diameter on the side close to the reboiler body 17 is larger, and its diameter is set to 100mm; to meet the flow and pressure requirements of the fluid flowing out of the reboiler body 17, provide a relatively spacious channel for the fluid, reduce the local resistance of the fluid when flowing out of the reboiler body 17, and enable the fluid to enter the connecting pipe 15 more smoothly. The pipe diameter on the side away from the reboiler body 17 is smaller, and the diameter is 80mm.

[0058] This design of gradually decreasing pipe diameter can accelerate the flow rate of the fluid to a certain extent. According to the principles of fluid mechanics, when the fluid flows from a large pipe diameter to a small pipe diameter, under the premise of conservation of mass, the flow rate will increase accordingly, which will help to increase the kinetic energy of the fluid in the subsequent transportation process, enabling it to better overcome factors such as pipeline resistance and gravity, and achieve more efficient transportation.

[0059] The variable diameter structure allows the fluid to gradually adjust the flow rate and pressure distribution in the process of flowing out of the reboiler body 17 and entering the connecting pipe 15, avoiding adverse flow phenomena such as eddy currents and turbulence caused by sudden changes in the pipe diameter. Eddy currents and turbulences will increase the energy loss of the fluid, reduce the fluid transportation efficiency, and may even cause damage such as erosion and corrosion to the pipeline. Through the transition of the variable diameter structure, the fluid can flow in the pipeline in a more stable and orderly state, reducing energy loss and improving the operating efficiency of the entire system.

[0060] The limiting groove 12 is annular and is arranged around the end of the connecting pipe 15 on one side opposite to the conveying pipe 14. This annular design can fully surround the circumference of the connecting part, ensuring that effective sealing and positioning functions can be provided in all directions.

[0061] The limiting groove 12 is tightly matched with the sealing strip 13, and the shape and size of the sealing strip 13 are adapted to the limiting groove 12, and can completely fill the space of the limiting groove 12 to form a reliable sealing interface. When the connecting pipe 15 is connected to the delivery pipe 14, the sealing strip 13 is squeezed in the limiting groove 12, so as to fit tightly to the surface of the connection part to prevent the passage of fluid or gas.

[0062] The shape and structure design of the limit groove 12 plays a key role in ensuring the connection sealing and positioning, and is an indispensable and important part of the reboiler connection protection structure. It works together with the sealing strip 13, the mounting block 18 and the positioning plate 7 to achieve a safe, stable and efficient connection between the connecting pipe 15 and the delivery pipe 14.

[0063] The delivery pipe 14 is a cylindrical pipe body, which has many advantages in fluid delivery. The cylindrical shape allows the fluid to be evenly distributed around the pipe wall when flowing in the pipe, reducing the local flow velocity difference and pressure change caused by the irregular shape. For example, compared with a square pipe, the fluid flow in a cylindrical pipe is more stable, and it is not easy to form dead zones and eddies, thereby reducing energy loss and improving delivery efficiency.

[0064] The shape and structure of the delivery pipe 14 are designed to meet the overall operating requirements of the reboiler system, play a key role in stable and efficient transmission during fluid delivery, and can cooperate well with other components such as the connecting pipe 15 to jointly realize the various functions of the reboiler.

[0065] The mounting block 18 is a rectangular parallelepiped structure. This rectangular parallelepiped design is convenient for coordination and installation with other components. It has a certain volume and a regular shape, and can be stably present at the connection portion between the connecting pipe 15 and the delivery pipe 14, providing a reliable structural basis for achieving the sealing and positioning functions.

[0066] The mounting block 18 is fixedly connected to both sides of the sealing strip 13 to form an integral component with the sealing strip 13. The connection method ensures that the mounting block 18 and the sealing strip 13 will not be relatively displaced during installation and use, thereby ensuring the integrity and stability of the sealing structure.

[0067] In the reboiler connection structure, the mounting block 18 plays a key auxiliary role. When the positioning plate 7 moves under the drive of the positioning mechanism, the positioning plate 7 interacts with the mounting block 18. Specifically, the opposite side of the positioning plate 7 is movably connected to the mounting block 18. By applying pressure to the mounting block 18, the sealing strip 13 is tightly pressed into the limiting groove 12, thereby achieving a reliable seal between the connecting pipe 15 and the delivery pipe 14. This sealing method can effectively prevent fluid or gas leakage at the connection point and ensure the safe and stable operation of the reboiler system.

[0068] The presence of the mounting block 18 at the connection position increases the overall stability of the connection structure. It and the sealing strip 13 together form a relatively strong component, which can better maintain the structural integrity of the connection position when affected by external factors such as fluid pressure and vibration, prevent the sealing strip 13 from shifting or falling off, and further ensure the reliability and sealing of the connection.

[0069] Reboiler connection protection structure

[0070] Overall protection layout and connection method

[0071] From the structural diagram, the connection protection structure of the reboiler is developed around the connection between the connecting pipe 15 and the delivery pipe 14. The connecting pipe 15 is connected to the reboiler body 17, and the delivery pipe 14 is connected to the connecting pipe 15. The two are sealed and protected through an innovative connection method. On the side opposite to the connecting pipe 15 and the delivery pipe 14, an annular limit groove 12 is provided. This annular design surrounds the connection part to form a continuous sealing and positioning area. The document does not specify the specific connection details by bolts or other fastening methods, but similar structures often use bolts to connect the connecting pipe 15 and the delivery pipe 14 together, so that the entire connection part is in a relatively closed space, thereby achieving wrapping protection for the connection point.

[0072] Sealing protection mechanism of limit groove and sealing strip

[0073] The limit groove 12 is 5 mm deep and 10 mm wide, and two sealing strips 13 fit tightly inside it. The material of the sealing strip 13 may be rubber or other polymer materials with good sealing performance and corrosion resistance. The document does not mention it, but it is speculated based on the function. When the connecting pipe 15 is connected to the delivery pipe 14, the sealing strip 13 is squeezed and filled in the limit groove 12, effectively preventing the fluid or gas from leaking from the connection point. This sealing structure is crucial to the safe operation of the reboiler, especially when dealing with toxic, flammable or corrosive fluids. Preventing leakage can avoid serious safety accidents and environmental pollution. For example, in chemical production, if the reboiler is used to distill a mixture containing harmful chemicals, a good seal can ensure a safe and reliable production process.

[0074] Co-location of mounting block and positioning plate

[0075] The sealing strip 13 is fixedly connected to two sides with a mounting block 18 of a rectangular structure, which is 30 mm long, 20 mm wide and 15 mm high. The positioning mechanism on one side of the shell 1 cooperates with the mounting block 18 to achieve precise positioning and further fixation of the connection point. The motor 3 in the positioning mechanism is installed on the shell 1 through the fixed seat 2. The output shaft of the motor 3 drives the gear 4 to rotate, and the gear 4 engages with the rack 5 to move the rack 5. The connecting block 6 on one side of the rack 5 passes through the through hole 10 on the shell 1, and the connecting block 6 drives the positioning plate 7 to move. The anti-slip pad 8 on the opposite side of the positioning plate 7 contacts the mounting block 18. When the equipment is running, the positioning plate 7 tightly fixes the mounting block 18 to ensure that the sealing strip 13 remains sealed in the limit groove 12, preventing the connection point from loosening due to vibration or other external forces, and further enhancing the stability and reliability of the connection protection structure.

[0076] The shell protects and supports the internal components

[0077] The shell 1 provides external protection and a support frame for the entire connection protection structure. The shell 1 is in the shape of a rectangular parallelepiped. Judging from the structural diagram and related descriptions, its internal space accommodates components such as the positioning mechanism to protect these components from external environmental factors such as dust and moisture. At the same time, the shell 1 provides a stable installation foundation for components such as the motor 3 through structures such as the fixing seat 2, ensuring that the positioning mechanism can work normally, and indirectly ensuring the effectiveness of the connection protection structure. For example, in an industrial production environment, the shell 1 can prevent debris from entering and affecting the meshing of the gear 4 and the rack 5, ensuring that the protection function of the connection point is continuous and stable.

[0078] In summary, the connection protection structure of the reboiler effectively wraps the connection points through the ingenious design and coordinated work of various components, realizes the sealing, positioning and protection functions, improves the safety, stability and service life of the equipment, and is of great significance in the application of reboilers in chemical and other industries.

[0079] A method for using a reboiler with a connection protection structure comprises the following steps:

[0080] Step 1: Initial Sealing and Protection Stage

[0081] When the reboiler starts working, the connecting pipe 15 and the delivery pipe 14 are closely matched through the limiting groove 12 and the sealing strip 13 to form a reliable sealing connection; the limiting groove 12 is annular, with a depth of 5mm and a width of 10mm, and the sealing strip 13 is tightly embedded therein to effectively prevent fluid or gas leakage;

[0082] At this time, the fluid or gas is completely blocked by the sealing strip 13 at the connection between the connecting pipe 15 and the delivery pipe 14, ensuring the stability of the internal pressure of the system, maintaining the integrity and safety of the system, and reducing the risk of accidents caused by leakage; at the same time, the connection protection structure wraps the connection point to prevent the external environment from eroding the connection point, reducing the possibility of equipment failure and damage, and reducing the heat loss from the connection point to the surrounding environment, thereby improving energy efficiency;

[0083] Step 2: Disassembly preparation phase when repair or replacement of parts is required

[0084] The user starts the motor 3, and the output shaft of the motor 3 starts to rotate. The motor 3 can be a small and efficient motor with a power of [X] kilowatts, which is determined according to the actual equipment requirements. The output shaft speed can reach [Y] revolutions per minute, which is determined according to factors such as the gear ratio. The rotation of the output shaft of the motor 3 drives the gear 4 fixedly connected thereto to rotate. The gear 4 meshes with the racks 5 provided on both sides of the inner cavity of the housing 1. The module of the gear 4 is set to [M], which is determined according to the requirements of the transmitted torque, and the number of teeth is [Z], which is designed to cooperate with the rack 5. Through precise meshing transmission, the rotational motion of the motor 3 is converted into the linear motion of the rack 5.

[0085] Step 3: Connection and Release Phase

[0086] Driven by the gear 4, the rack 5 starts to move, and the connecting block 6 fixedly connected to one side of the rack 5 moves synchronously therewith. The connecting block 6 slides in the through hole 10 opened on one side of the shell 1. The through hole 10 has a diameter of 30 mm, which provides a stable sliding channel for the connecting block 6, ensuring that the moving direction of the connecting block 6 is accurate and stable; the movement of the connecting block 6 drives the positioning plates 7 to move toward each other, and the opposite sides of the positioning plates 7 are fixedly connected with anti-skid pads 8. The longitudinal striped texture provided on the surface of the anti-skid pads 8 increases the friction between the mounting block 18, ensuring accurate and stable positioning. As the positioning plates 7 move toward each other, the fixing effect of the positioning plates 7 on the mounting block 18 is gradually released, so that the connection between the connecting pipe 15 and the conveying pipe 14 is in a detachable state, which is convenient for the subsequent maintenance or replacement of components of the conveying pipe 14;

[0087] Step 4: Reinstallation phase after repair or replacement of parts is completed

[0088] When the repair or replacement of parts is completed, the delivery pipe 14 is reconnected with the connecting pipe 15, so that the sealing strip 13 is accurately embedded in the limiting groove 12, and the mounting block 18 is located at the initial action position of the positioning plate 7. Then the reverse control of the motor 3 can be realized by circuit design, the motor 3 drives the gear 4 to reverse, and then drives the rack 5 to move in the opposite direction, the connecting block 6 and the positioning plate 7 to move in the opposite direction, and the positioning plate 7 re-applies pressure to the mounting block 18, and the sealing strip 13 is pressed tightly into the limiting groove 12 again, so that the connecting pipe 15 and the delivery pipe 14 are reconnected tightly, ensuring that the equipment returns to normal operation. The whole process is easy to operate, effectively improving the maintenance efficiency and reducing the maintenance time.

[0089] The working principle and use process of the present invention:

[0090] First, when protecting the connecting pipe 15 and the delivery pipe 14 of the reboiler body 17, the cooperation of the limit groove 12 and the sealing strip 13 provides good sealing performance, ensures that there is no leakage between the connection points, prevents fluid or gas leakage, and thus maintains the integrity and safety of the system. When the delivery pipe 14 needs to be disassembled, the user starts the motor 3, and the output shaft of the motor 3 rotates while driving the gear 4 to rotate. The gear 4 rotates while driving the racks 5 on both sides to engage and transmit. The rack 5 moves while driving the connecting block 6 to move. The connecting block 6 moves while driving the positioning plate 7 to move toward each other, so that the positioning plate 7 releases the fixing of the mounting block 18, making the repair and maintenance of the reboiler body 17 easier. When repairs or replacement of parts are required, the connection can be easily disassembled, which improves the repair efficiency and reduces the repair time.

[0091] The motor 3 drives the gear 4 to rotate through its output shaft. The gear 4 meshes with the racks 5 on both sides of the inner cavity of the housing 1. When the gear 4 rotates, its teeth mesh with the teeth of the rack 5, thereby converting the rotational motion into linear motion. A connecting block 6 is fixedly connected to one side of the rack 5. Therefore, when the rack 5 moves, the connecting block 6 moves linearly therewith, passes through the through hole 10 provided on the housing 1, and transmits the motion to the positioning plate 7.

[0092] The opposite side of the positioning plate 7 is in contact with the mounting block 18 through a movable connection; when the motor 3 drives the gear 4 to drive the rack 5 to move, the positioning plate 7 is pushed above the mounting block 18. The anti-skid pad 8 fixedly connected to the positioning plate 7 increases the friction force through the longitudinal stripe texture on its surface, exerting pressure on the mounting block 18. This pressure presses the sealing strip 13 tightly into the limiting groove 12, thereby ensuring reliable sealing and fixation of the connection part.

[0093] The limiting groove 12, the sealing strip 13, the mounting block 18 and other components cooperate with each other to ensure the sealing and connection between the delivery pipe 14 and the connecting pipe 15. The positioning mechanism in the housing 1 is composed of a motor 3, a gear 4, a rack 5, and a connecting block 6 to ensure the precise movement of the positioning plate 7.

[0094] The positioning mechanism drives the positioning plate 7 to apply pressure, so that the mounting block 18 presses the sealing strip 13; the motion conversion between the gear and the rack facilitates disassembly and reassembly. This structural design meets the requirements of efficient and stable connection and disassembly, while improving the safety and maintenance convenience of the reboiler.

[0095] The mounting blocks 18 are located on both sides of the sealing strip 13 and are fixedly connected to the sealing strip 13. The sealing strip 13 is embedded in the limiting grooves 12 of the delivery pipe 14 and the connecting pipe 15, and a reliable seal between the two pipes is achieved through the elastic deformation of the sealing strip. The presence of the mounting blocks 18 increases the stability of the sealing structure and prevents the sealing strip from shifting or falling off due to external force or vibration. The positioning plate 7 of the positioning mechanism stabilizes the connection point by applying pressure to the mounting blocks 18, thereby further achieving precise docking between the two pipes.
