Description

Technical Field

[0001] This utility model relates to the field of sealed reaction vessels, and in particular to a leak-proof sealed reaction vessel for the production of rosin-based solvents. Background Technology

[0002] In the production process of rosin-based solvents, the reactor is a core piece of equipment, and its sealing performance directly affects the solvent recovery rate and production safety. Existing reactors used for rosin-based solvent production typically have sealing components installed at the joint between the reactor body and the lid, secured by multiple sets of fastening structures. Additionally, sealing components are used at the penetration point between the stirring component and the lid to reduce leakage and loss of the solvent due to its volatile nature, ensuring the airtightness of the reaction process.

[0003] However, some small and medium-sized reaction vessels used for the production of rosin-based solvents have some shortcomings: First, the fastening structure between the vessel body and the lid is not only cumbersome to disassemble and assemble when frequently opened and closed, but also prone to reduced sealing performance due to uneven stress. In addition, the connection between the stirring components and the drive components is mostly an integrated design or fixed with bolts. When it is necessary to clean, maintain or replace the stirring components, the disassembly and assembly process is time-consuming, and repeated disassembly and assembly can easily cause wear at the sealing points, indirectly increasing the risk of solvent leakage and reducing the practicality of the equipment.

[0004] Therefore, those skilled in the art have provided leak-proof sealed reactors for the production of rosin-based solvents to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a leak-proof sealed reactor for the production of rosin-based solvents. The device utilizes the elasticity of the spring and the limiting effect of the retaining ring in a convenient fixing mechanism, which eliminates the need for complex tools when fixing the reactor lid to the reactor body. Furthermore, the sealing ring always maintains a stable fit, reducing the risk of rosin-based solvent leakage and improving the practicality of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A leak-proof sealed reactor for the production of rosin-based solvents includes a base, reactor body, controller, reactor cover, sealing ring, feed inlet, servo motor, stirring rod, sealing bearing, and discharge valve. The reactor body is fixedly connected to a convenient fixing mechanism on all four sides of the upper part of the outer wall, and the output end of the servo motor is fixedly connected to a quick disassembly mechanism. The convenient fixing mechanism includes multiple first threaded rods. A connecting plate is fixedly connected to the middle of the outer wall of each first threaded rod. Guide rods are fixedly connected to both sides of the outer wall of the connecting plate. A clamping nut is threaded to one end of each first threaded rod. One end of a spring is fixedly connected to one side of the connecting plate. The other end of the spring is fixedly connected to one side of a pressure plate. Pins are fixedly connected to both ends of one side of the pressure plate. A rotating cylinder is rotatably connected to one end of the outer wall of each first threaded rod. Connecting blocks are fixedly connected to both sides of the outer wall of the rotating cylinder. A retaining ring is fixedly connected to one end of the connecting block. One end of the retaining ring is fixedly connected to one end of the outer wall of a limiting post. Fixing blocks are fixedly connected to all four sides of the lower end of the lid. An arc-shaped limiting groove is opened on one end of one side of each fixing block. Through the above technical solution, the device utilizes the elastic cooperation of the spring and the limiting effect of the retaining ring in the convenient fixing mechanism, so that the fixing operation of the vessel lid and the reactor body does not require complicated tools, and the sealing ring always maintains a stable fit, reducing the risk of rosin-based solvent leakage and improving the practicality of the device.

[0007] Furthermore, the quick-assembly and disassembly mechanism includes a mounting base. Two second threaded rods are fixedly connected to both sides of one end of the outer wall of the mounting base. A positioning nut is threaded to one end of each second threaded rod. Insertion sleeves are fixedly connected to both sides of the other end of the outer wall of the mounting base. A slip ring is rotatably connected to the middle of the outer wall of the mounting base. An extension rod is fixedly connected to both ends of one side of the slip ring. An arc-shaped insert rod is fixedly connected to one side of the upper end of the outer wall of the extension rod. A collar is fixedly connected to both ends of the other side of the slip ring. A positioning groove is provided in the middle of one side of the collar. One end of the mounting base is engaged with one end of a stirring rod. L-shaped insert rods are fixedly connected to both sides of one end of the outer wall of the stirring rod. The inner wall of a sealing bearing is fixedly connected to one side of the outer wall of the mounting base. Through the above technical solution, the device uses the arc-shaped plug and L-shaped plug engagement design of the quick disassembly mechanism to make the connection and disassembly of the stirring rod and the servo motor efficient and convenient, while not affecting the sealing performance of the sealed bearing, reducing equipment maintenance time and improving the practicality of the device.

[0008] Furthermore, the upper end of the base is fixedly connected to the reactor body, a controller is provided on one side of the middle of the outer wall of the reactor body, a lid is provided at the upper end of the reactor body, a sealing ring is fixedly connected to the edge of the lower end face of the lid, a feed inlet is opened at one end of the upper end face of the lid, a servo motor is provided in the middle of the upper end face of the lid, a stirring rod is engaged at one end of the quick disassembly mechanism, the inner wall of a sealing bearing is fixedly connected to one side of the outer wall of the opening in the middle of the upper end face of the lid, a discharge valve is provided at the lower end of the reactor body, and the controller and the servo motor are electrically connected. Through the above technical solution, the sealing ring and the sealing bearing form a double sealing foundation, and the controller realizes accurate control of the servo motor, ensuring the stability and sealing of the equipment operation.

[0009] Furthermore, one end of the pin is engaged with one side of the connecting block, one end of the guide rod passes through one side of the pin and is slidably connected thereto, and one end of the limiting post is slidably connected to one side of the outer wall of the arc-shaped limiting groove. Through the above technical solution, the guide rod provides sliding guidance for the pin, and the cooperation between the limiting post and the arc-shaped limiting groove achieves initial positioning, ensuring that the various components of the convenient fixing mechanism work together in an orderly manner.

[0010] Furthermore, when one end of the limiting post abuts against one end of the outer wall of the arc-shaped limiting groove, the clamping nut is tightened, the pressure plate slides towards the direction of the connecting plate, the spring is passively compressed, and one end of the pin forms a locking connection with one side end face of the connecting block. When the clamping nut is loosened, the spring naturally rebounds, one end of the pin disengages from one side end face of the connecting block, and one end of the limiting post disengages from one end of the outer wall of the arc-shaped limiting groove. The above technical solution enables rapid fixing and unlocking of the vessel lid and the reactor body. The elasticity of the spring can compensate for the sealing gap and improve the sealing performance of the vessel.

[0011] Furthermore, the width of the opening on one side of the outer wall of the collar is consistent with the diameter of the second threaded bar, and the diameter of the positioning nut is consistent with the bottom diameter of the positioning groove; The above technical solution ensures that the collar can be accurately fitted onto the second threaded bar, and the positioning nut can be stably embedded in the positioning groove, providing a reliable positioning basis for the quick assembly and disassembly mechanism.

[0012] Furthermore, one end of the arc-shaped plug penetrates one side end face of the plug-in cylinder and forms a snap-fit ​​connection with one end of the L-shaped plug, and the snap-fit ​​directions of the two arc-shaped plugs and the L-shaped plug are opposite; The above technical solution enhances the stability of the connection between the stirring rod and the mounting base, preventing the connection from loosening due to stress during the stirring process.

[0013] Furthermore, after the slip ring rotates at a certain angle, one end of the arc-shaped insert rod and one end of the L-shaped insert rod form a locking connection. The collar is sleeved on the middle of the outer wall of the second threaded rod. The positioning nut is tightened and abuts against the bottom surface of the positioning groove. When the positioning nut is loosened, the collar disengages from the second threaded rod, and one end of the arc-shaped insert rod disengages from one end of the L-shaped insert rod. With the above technical solution, the stirring rod can be disassembled and assembled simply by rotating the slip ring and loosening the positioning nut. The operation is convenient and does not damage the sealing structure, thus improving the maintenance efficiency of the equipment.

[0014] This utility model has the following beneficial effects: 1. The leak-proof sealed reactor for the production of rosin-based solvents proposed in this utility model uses the elastic cooperation of springs and the limiting effect of retaining rings in the convenient fixing mechanism to make the fixing operation of the reactor lid and the reactor body without complicated tools, and the sealing ring always maintains a stable fit, reducing the risk of rosin-based solvent leakage and improving the practicality of the device.

[0015] 2. The leak-proof sealed reactor for producing rosin-based solvents proposed in this utility model features a quick-disassembly mechanism with an arc-shaped plug and an L-shaped plug engaging design. This design makes the connection and disassembly of the stirring rod and the servo motor efficient and convenient, without affecting the sealing performance of the sealing bearing. This reduces equipment maintenance time and improves the practicality of the device. Attached Figure Description

[0020] Reference Figure 3-7The quick-assembly / disassembly mechanism 9 includes a mounting base 91. Two second threaded rods 92 are fixedly connected to both sides of one end of the outer wall of the mounting base 91. A positioning nut 93 is threaded to one end of each second threaded rod 92. Insertion sleeves 94 are fixedly connected to both sides of the other end of the outer wall of the mounting base 91. A slip ring 95 is rotatably connected to the middle of the outer wall of the mounting base 91. An extension rod 96 is fixedly connected to both ends of one side of the slip ring 95. An arc-shaped insertion rod 97 is fixedly connected to one side of the upper end of the outer wall of the extension rod 96. A collar 98 is fixedly connected to both ends of the other side of the slip ring 95. A positioning groove 99 is provided in the middle of one side end face of 98. One end of the mounting base 91 is engaged with one end of the stirring rod 10. Both sides of one end of the outer wall of the stirring rod 10 are fixedly connected with L-shaped inserts 910. One side of the outer wall of the mounting base 91 is fixedly connected to the inner wall of the sealing bearing 11. The device uses the arc-shaped insert 97 of the quick disassembly mechanism 9 to engage with the L-shaped insert 910, which makes the connection and disassembly of the stirring rod 10 and the servo motor 8 efficient and convenient, while not affecting the sealing performance of the sealing bearing 11, reducing equipment maintenance time and improving the practicality of the device. The upper end of the base 1 is fixedly connected to the reactor body 2. A controller 3 is set on one side of the middle of the outer wall of the reactor body 2. The upper end of the reactor body 2 is set with a lid 5. A sealing ring 6 is fixedly connected to the edge of the lower end face of the lid 5.

A stirring rod 10 is engaged at one end of the quick disassembly mechanism 9. The inner wall of the sealing bearing 11 is fixedly connected to one side of the outer wall of the opening in the middle of the upper end face of the lid 5. A discharge valve 12 is set at the lower end of the reactor body 2. The controller 3 and the servo motor 8 are electrically connected. The sealing ring 6 and the sealing bearing 11 form a double sealing base. The controller 3 realizes accurate control of the servo motor 8, ensuring the stability and sealing of the equipment operation. One end of the pin 47 is engaged with one side of the connecting block 49. One end of the guide rod 43 passes through one side of the pin 47 and is slidably connected to it. One end of the limiting post 411 is slidably connected to one side of the outer wall of the arc-shaped limiting groove 413. The guide rod 43 provides sliding guidance for the pin 47. The cooperation between the limiting post 411 and the arc-shaped limiting groove 413 achieves initial positioning, ensuring that the components of the convenient fixing mechanism 4 work together in an orderly manner. When one end of the limiting post 411 abuts against one end of the outer wall of the arc-shaped limiting groove 413, the clamping nut 44 is tightened, the pressure plate 46 slides in the direction of the connecting plate 42, the spring 45 is passively compressed, and one end of the pin 47 forms a locking connection with one side end face of the connecting block 49. When the clamping nut 44 is loosened, the spring 45 naturally rebounds, one end of the pin 47 disengages from one side end face of the connecting block 49, and one end of the limiting post 411 disengages from one end of the outer wall of the arc-shaped limiting groove 413, thereby realizing the rapid fixing and unlocking of the vessel cover 5 and the reactor body 2. The elastic effect of the spring 45 can compensate for the sealing gap and improve the sealing performance of the vessel body. The width of the opening on one side of the outer wall of the collar 98 is consistent with the diameter of the second threaded bar 92, and the diameter of the positioning nut 93 is consistent with the bottom diameter of the positioning groove 99, ensuring that the collar 98 can be accurately fitted onto the second threaded bar 92 and the positioning nut 93 can be stably embedded into the positioning groove 99, providing a reliable positioning basis for the quick disassembly and assembly mechanism 9. One end of the arc-shaped plug 97 passes through one side end face of the plug-in cylinder 94 and forms a snap-fit ​​connection with one end of the L-shaped plug 910. The two arc-shaped plugs 97 and the L-shaped plug 910 snap-fit ​​in opposite directions, which enhances the connection stability between the stirring rod 10 and the mounting base 91 and avoids loosening of the connection due to force during the stirring process. After the slip ring 95 rotates to a certain angle, one end of the arc-shaped insert rod 97 and one end of the L-shaped insert rod 910 are engaged. The collar 98 is fitted onto the middle of the outer wall of the second threaded rod 92. The positioning nut 93 is tightened and abuts against the bottom surface of the positioning groove 99. When the positioning nut 93 is loosened, the collar 98 is disengaged from the second threaded rod 92, and one end of the arc-shaped insert rod 97 is disengaged from one end of the L-shaped insert rod 910. The disassembly and assembly of the stirring rod 10 can be completed simply by rotating the slip ring 95 and loosening the positioning nut 93. The operation is convenient and does not damage the sealing structure, thus improving the maintenance efficiency of the equipment.

[0021] Working principle: Before use, place the lid 5 on the upper end of the reactor body 2. Rotate the rotating cylinder 48 of the convenient fixing mechanism 4 to make the retaining ring 410 drive the limiting post 411 to slide into the arc-shaped limiting groove 413 of the fixing block 412. Tighten the clamping nut 44 to push the pressure plate 46 to compress the spring 45. The pin 47 slides along the guide rod 43 and engages with the connecting block 49 to complete the fixing of the lid 5. The sealing ring 6 then fits tightly against the port of the reactor body 2. The rosin-based solvent and auxiliary materials are injected into the reactor body 2 through the feed inlet 7. The controller 3 controls the servo motor 8 to drive the mounting base 91 of the quick disassembly mechanism 9 to rotate. The mounting base 91 drives the stirring rod 10 through the engaging structure formed by the arc-shaped insert 97 and the L-shaped insert 910 fixed at one end of the stirring rod 10. The synchronous rotation stirs and mixes the materials in the reactor. The sealed bearing 11 blocks the solvent leakage path when the stirring rod 10 rotates. During the reaction, the controller 3 adjusts the speed of the servo motor 8 in real time to adapt to the process requirements. After the reaction is completed, the controller 3 controls the servo motor 8 to stop. Loosening the clamping nut 44 causes the spring 45 to rebound and drive the pin 47 to disengage from the connecting block 49. Rotating the rotating drum 48 in the opposite direction causes the limiting post 411 to exit the arc-shaped limiting groove 413. The reactor cover 5 can then be opened to clean the inside of the reactor body 2. When the stirring rod 10 needs maintenance, loosening the positioning nut 93 and rotating the slip ring 95 causes the arc-shaped insert 97 to disengage from the L-shaped insert 910. At the same time, the collar 98 separates from the second threaded rod 92, and the stirring rod 10 can then be removed for cleaning or replacement.
