Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a rapid batch change reactor. Background Technology

[0002] A reaction vessel is a container used for physical or chemical reactions. Through structural design and parameter configuration, it achieves functions such as heating, evaporation, cooling, and mixing. It is widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries, and serves as a pressure vessel for completing processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation.

[0003] The function of a reaction vessel is to provide a specific environment (such as temperature, pressure, etc.) for a chemical reaction, to promote the full mixing of reactants, control the reaction process, and thus realize various physical or chemical processes (such as polymerization, condensation, etc.).

[0004] In existing technologies, most mainstream reactors are fixed structures. During batch changeovers, the traditional method of complete disassembly and cleaning requires the reactor to be completely disassembled for manual cleaning. This process is not only cumbersome but also results in extremely long downtime, typically 4-8 hours. Such long downtime significantly reduces production efficiency and increases production costs. Therefore, a rapid batch changeover reactor is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rapid batch change reactor, which aims to improve the problem of low batch change efficiency in existing reactors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rapid batch change reactor includes a reactor body, an inner liner detachably connected to the interior of the reactor body, a disassembly and assembly mechanism fixedly connected to the top of the reactor body, a top cover fixedly connected to the top of the inner liner, and a sealing mechanism provided inside the top cover.

[0008] The disassembly and assembly mechanism includes a flange, the bottom of which is fixedly connected to the top of the vessel body. Multiple hydraulic cylinders are fixedly connected to the bottom inner wall of the flange. A circular block is fixedly connected to the drive end of each hydraulic cylinder. A convex plate is fixedly connected to the far side of each of the multiple circular blocks. A transmission plate is rotatably connected inside the convex plate. A transmission plate is rotatably connected to the top of the transmission plate. A rotating block is rotatably connected to the top of the transmission plate. A pressure plate is fixedly connected to the near side of each of the multiple rotating blocks. A buffer assembly is fixedly connected to the bottom of the inner liner.

[0009] Through the above technical solutions: the vessel body and the inner liner are detachably connected, and with the top disassembly and assembly mechanism, the inner liner can be quickly replaced, greatly shortening the batch changeover time; the top cover and sealing mechanism are combined to form a double seal to prevent material leakage; the buffer component avoids impact during the loading and unloading of the inner liner, ensuring stable operation of the equipment and improving overall production efficiency and safety.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the flange one is fixedly connected to multiple support plates, and the middle part of the transmission plate two is rotatably connected to the inside of the support plates;

[0012] Through the above technical solution: the support plate provides a rotation fulcrum for the transmission plate two, ensuring that the transmission plate two remains stable during movement, making the transmission of each component in the disassembly and assembly mechanism more precise and reliable, ensuring that the pressure plate smoothly presses or releases the inner liner, and ensuring the smooth disassembly and assembly process of the inner liner.

[0013] As a further description of the above technical solution:

[0014] The buffer assembly includes a positioning post, the top end of which is fixedly connected to the bottom end of the inner liner. A guide seat is fixedly connected to the bottom inner wall of the vessel body, and a buffer washer is fixedly connected to the top end of the guide seat.

[0015] The above technical solution involves a positioning post, a guide seat, and a buffer washer forming a buffer assembly. The positioning post slides along the guide seat to achieve precise positioning of the inner liner, while the buffer washer absorbs the impact force of the inner liner falling, protecting it from damage, extending its service life, and improving equipment reliability.

[0016] As a further description of the above technical solution:

[0017] The positioning column has an outlet inside, and the top of the top cover has an inlet.

[0018] The above technical solution facilitates the discharge of materials after reaction through the outlet in the positioning column, and the inlet in the top cover facilitates the input of materials, optimizes the material input and output process, reduces material residue, improves reaction efficiency, and makes operation more convenient and efficient.

[0019] As a further description of the above technical solution:

[0020] The top side of the buffer washer contacts the bottom side of the inner liner, the outer wall of the positioning post is slidably connected to the inner wall of the guide seat and the buffer washer, and the outer wall of the positioning post is slidably connected to the bottom inner wall of the vessel body.

[0021] The above technical solution clarifies the fit between the buffer gasket and the inner liner, the positioning column and the guide seat and the vessel body, ensuring accurate positioning and effective buffering during the installation of the inner liner, enhancing the stability of the inner liner within the vessel body, and preventing shaking during operation from affecting the reaction effect.

[0022] As a further description of the above technical solution:

[0023] A heating jacket is fixedly connected to the inner wall of the vessel body, and a support base is fixedly connected to the bottom of the vessel body. Support columns are fixedly connected to the four corners of the bottom end of the support base.

[0024] Through the above technical solutions: the heating jacket can accurately control the reaction temperature to meet the needs of different chemical reactions; the support base and support column provide stable support for the reactor, ensuring that the equipment remains stable during operation and preventing safety accidents caused by shaking or tilting.

[0025] As a further description of the above technical solution:

[0026] The sealing mechanism includes a second flange, the top of which is fixedly connected to the bottom of the top cover. An inner annular groove is formed inside the second flange, and an inner sealing ring is fixedly connected to the inner wall of the inner annular groove. An outer annular groove is formed on the outer side of the second flange, and an outer sealing ring is fixedly connected to the inner wall of the outer annular groove.

[0027] The above technical solution involves installing double sealing rings through the inner and outer annular grooves on flange two, forming a double sealing structure. Even if a single sealing ring malfunctions, it can still effectively prevent material leakage and the entry of external impurities, ensuring a stable reaction environment.

[0028] As a further description of the above technical solution:

[0029] The inner walls of the plurality of pressure plates are in contact with the outer wall of the second flange, the bottom side of the second flange is in contact with the top side of the first flange, and the bottom sides of the inner sealing ring and the outer sealing ring are in contact with the top side of the first flange.

[0030] The above technical solution clarifies the position and contact relationship between the pressure plate, flange one, flange two, and sealing ring, ensuring that the sealing ring can fit tightly when the pressure plate is tightened, achieving a reliable seal. At the same time, it ensures a stable connection between the inner liner and the reactor body, providing a safe and reliable environment for the reaction.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the flange one in the disassembly and assembly mechanism provides a stable installation position for multiple hydraulic cylinders. The multiple hydraulic cylinders serve as a power source and can precisely control the up and down movement of the circular block. During batch change, the hydraulic cylinders contract synchronously, driving the convex plate to rise. Through the coordinated movement of a series of transmission components such as transmission plate one and transmission plate two, the pressure plate opens outward, releasing the pressure on flange two, allowing the inner liner to be quickly lifted out. When installing a new inner liner, the operation is reversed. Compared with the traditional batch change method, the batch change time is greatly shortened from the traditional hour to within minutes, significantly improving production efficiency, reducing equipment downtime, and bringing higher production capacity to chemical production.

[0033] 2. In this utility model, the flange two of the sealing mechanism is provided with an inner annular groove and an outer annular groove, and an inner sealing ring and an outer sealing ring are respectively installed. Both are made of fluororubber O-rings, forming a double sealing structure. Under the pressure of the pressure plate, they are tightly attached to the top side of the flange one, effectively preventing material leakage and the entry of external impurities. Even if one O-ring has a problem, the other can still maintain the seal, ensuring a stable reaction environment and guaranteeing product quality. The buffer gasket of the buffer assembly is located at the top of the guide seat and contacts the bottom of the inner tank. When the inner tank falls, it can effectively reduce the impact and avoid damage to the inner tank. At the same time, the positioning column slides on the inner wall of the guide seat and the buffer gasket, further enhancing the stability of the inner tank, reducing the shaking of the inner tank during equipment operation, and extending the service life of the equipment.

[0040] 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.

[0041] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a rapid batch change reactor, including a reactor body 1, which is the outer shell structure of the entire reactor, providing a closed space for the reaction. The reactor body 1 is detachably connected to an inner liner 2, which is made of 316L stainless steel. 316L stainless steel has good corrosion resistance and can resist the erosion of chemical materials, ensuring that the inner liner 2 will not be corroded or damaged during long-term use, thus ensuring the service life of the reactor and the purity of the materials. The top of the reactor body 1 is fixedly connected to a disassembly and assembly mechanism 4, and the top of the inner liner 2 is fixedly connected to a top cover 3. The top cover 3 is provided with a sealing mechanism 5. The connection between the top cover 3 and the inner liner 2 ensures the sealing of the reactor interior, preventing material leakage and the entry of external impurities during the reaction, and providing a relatively closed environment for the reaction. The inner wall of the reactor body 1 is fixedly connected to a heating jacket 6, which adopts a semi-tube structure with a wall thickness of 8mm. Its main function is to heat the materials in the reactor. The bottom of the reactor body 1 is fixedly connected to a support base 8, and the four corners of the bottom of the support base 8 are fixedly connected to support columns 9.

[0042] Specifically, the vessel body 1 serves as the outer shell, providing a closed space to ensure a stable reaction environment. The inner liner 2 is made of 316L stainless steel, which is highly corrosion-resistant, extends the service life of the reactor, and ensures the purity of the materials. The top cover 3 is connected to the inner liner 2 to enhance the sealing performance and reduce material leakage and impurity intrusion. The semi-tubular structure of the heating jacket 6 effectively heats the materials to meet the reaction temperature requirements. The support base 8 and support column 9 provide stable support for the reactor and ensure the safe operation of the equipment.

[0043] The disassembly and assembly mechanism 4 includes a flange 401, the bottom of which is fixedly connected to the top of the vessel body 1. Multiple hydraulic cylinders 402 are fixedly connected to the inner bottom wall of the flange 401. The flange 401 provides installation positions for the hydraulic cylinders 402. A circular block 403 is fixedly connected to the drive end of each hydraulic cylinder 402. The hydraulic cylinder 402 is the power source of the disassembly and assembly mechanism 4. Through hydraulic drive, the up-and-down movement of the circular block 403 can be precisely controlled. A protruding plate 404 is fixedly connected to the opposite side of each of the multiple circular blocks 403. The internal rotation of the protruding plate 404... A transmission plate 405 is connected. When the circular block 403 moves up and down, the convex plate 404 moves up and down accordingly, thereby driving the transmission plate 405 to rotate, converting the vertical motion into an angular change of the transmission plate 405. A transmission plate 406 is rotatably connected to the top of the transmission plate 405. Multiple support plates 407 are fixedly connected to the outer wall of the flange 401. The middle part of the transmission plate 406 is rotatably connected to the inside of the support plate 407. A rotating block 408 is rotatably connected to the top of the transmission plate 406. The support plates 407 provide support and positioning for the transmission. The function of plate 406 is to provide a rotational support point for transmission plate 406, ensuring its stability during movement. Transmission plate 406 further converts the motion transmitted from transmission plate 405 and transmits it to rotating blocks 408. Multiple rotating blocks 408 have pressure plates 409 fixedly connected to adjacent sides. Driven by transmission plate 406, the rotating blocks 408 rotate, converting the motion of transmission plate 406 into radial motion of pressure plates 409, thereby enabling the pressure plates 409 to press and release the inner liner 2. The sealing mechanism 5 includes flanges. Flange 2 501 is fixedly connected to the bottom of the top cover 3. The inner walls of multiple pressure plates 409 are in contact with the outer walls of flange 2 501. When the inner liner 2 is disassembled and assembled, the pressure plates 409 move inward or outward through the rotation block 408. During installation, they press flange 2 501 inward to ensure the fixation of the inner liner 2. During disassembly, they open outward to release the fixation of the inner liner 2. They are the direct execution parts in the disassembly and assembly process of the inner liner 2. The bottom end of the inner liner 2 is fixedly connected to the buffer assembly 7.

[0044] Specifically, flange 401 of the disassembly and assembly mechanism 4 provides an installation base for hydraulic cylinder 402, ensuring structural stability. Hydraulic cylinder 402 precisely controls the movement of circular block 403, and through a series of transmission components, enables the pressure plate 409 to quickly press and release the inner liner 2, making the inner liner 2 easy to install and remove, significantly shortening batch changeover time and improving production efficiency. Flange 501 of the sealing mechanism 5 cooperates with pressure plate 409 to ensure that the inner liner 2 is firmly fixed, facilitating the replacement of the inner liner 2.

[0045] The buffer assembly 7 includes a positioning post 701, the top of which is fixedly connected to the bottom of the inner liner 2. A guide seat 702 is fixedly connected to the bottom inner wall of the vessel body 1, and a buffer washer 703 is fixedly connected to the top of the guide seat 702. The top side of the buffer washer 703 contacts the bottom side of the inner liner 2. When the inner liner 2 falls, the buffer washer 703 can absorb the impact force when the inner liner 2 contacts the bottom of the vessel body 1, preventing the inner liner 2 from being damaged by the impact. It can also support and stabilize the inner liner 2 to a certain extent. The outer wall of the positioning column 701 is slidably connected to the inner wall of the guide seat 702 and the buffer washer 703. The outer wall of the positioning column 701 is slidably connected to the bottom inner wall of the vessel body 1. The positioning column 701 has a discharge port inside. When installing the inner liner 2, the positioning column 701 slides along the inner wall of the guide seat 702 and the buffer washer 703 and the bottom inner wall of the vessel body 1, which plays a guiding and positioning role, ensuring that the inner liner 2 falls accurately into the bottom of the vessel body 1. At the same time, the discharge port facilitates the discharge of the material after the reaction. The top of the top cover 3 has a feed port 10 to facilitate the input of materials.

[0046] Specifically, the buffer gasket 703 of the buffer assembly 7 effectively absorbs the impact force when the inner liner 2 falls, protecting the inner liner 2 from damage, and also supports and stabilizes the inner liner 2. The positioning column 701 slides along the inner wall of the guide seat 702 and the buffer gasket 703 to achieve precise guidance and positioning, ensuring accurate installation of the inner liner 2. The outlet of the positioning column 701 facilitates material discharge, and the inlet of the top cover 3 facilitates material input, thus optimizing the process of reactant material input and output.

[0047] Reference Figure 1 , Figure 2 and Figure 4 The bottom side of flange 2 501 contacts the top side of flange 1 401. An inner annular groove 502 is formed inside flange 2 501, and an inner sealing ring 503 is fixedly connected to the inner wall of the inner annular groove 502. An outer annular groove 504 is formed on the outer side of flange 2 501, and an outer sealing ring 505 is fixedly connected to the inner wall of the outer annular groove 504. Flange 2 501 provides installation positions for the inner sealing ring 503 and the outer sealing ring 505, and also cooperates with pressure plate 409. During installation, the clamping force of pressure plate 409 achieves the connection with the flange. The flange 401 is tightly connected, with the bottom sides of the inner sealing ring 503 and the outer sealing ring 505 in contact with the top side of the flange 401. Both the inner sealing ring 503 and the outer sealing ring 505 are made of fluororubber O-rings. The double O-ring groove design forms a double sealing structure, which greatly improves the sealing performance. During the operation of the reactor, even if one O-ring is slightly worn or not sealing properly, the other O-ring can still play a sealing role, effectively preventing material leakage and the entry of external impurities, and ensuring the stability of the reaction environment and product quality.

[0048] Specifically, flange 2 501 provides installation positions for the inner and outer sealing rings and is tightly connected to flange 1 401. The inner sealing ring 503 and the outer sealing ring 505 are made of fluororubber O-rings. The double O-ring grooves form a double sealing structure. Even if one O-ring has a problem, the other can still seal, which greatly improves the sealing performance, effectively prevents material leakage and impurities from entering, and ensures the stability of the reaction environment and product quality.

[0049] Working principle: When the inner liner 2 needs to be replaced, the disassembly and assembly mechanism 4 is activated. Multiple hydraulic cylinders 402 retract synchronously, driving the round block 403 to move upward, thereby causing the convex plate 404 to rise. Since the first transmission plate 405 is rotatably connected to the convex plate 404, and the second transmission plate 406 is rotatably connected to the first transmission plate 405 and the rotating block 408 respectively, and the middle of the second transmission plate 406 is rotatably connected to the support plate 407, when the hydraulic cylinders 402 are activated, these transmission components move in concert, causing multiple pressure plates to rise. 409 opens outward, releasing the clamping state of flange 2 501. At this time, the inner liner 2 can be lifted vertically upward by external hoisting equipment. When installing the new inner liner 2, the inner liner 2 is hoisted to the top of the vessel body 1 and slowly lowered. The positioning column 701 at the bottom of the inner liner 2 is accurately lowered into the bottom of the vessel body 1 under the guidance of the guide seat 702. Then, the hydraulic cylinder 402 extends, driving the round block 403 to descend, causing the pressure plate 409 to move inward, clamping flange 2 501, and completing the installation of the inner liner 2.

[0050] After the inner liner 2 is installed, the sealing mechanism 5 comes into play. Under the pressure of the pressure plate 409, the inner sealing ring 503 and the outer sealing ring 505 on the flange 2 501 are tightly fitted to the top side of the flange 1 401, forming a double sealing structure, which effectively prevents material leakage and the entry of external impurities. The buffer assembly 7 also comes into play at this time. The buffer gasket 703 is located at the top of the guide seat 702 and contacts the bottom of the inner liner 2. When the inner liner 2 falls, the buffer gasket 703 can reduce the impact between the inner liner 2 and the bottom of the reactor body 1, avoiding damage to the inner liner 2. At the same time, the positioning column 701 slides on the inner wall of the guide seat 702 and the buffer gasket 703, which further enhances the stability of the inner liner 2 and ensures that the inner liner 2 will not shake during the operation of the reactor, ensuring the smooth progress of the reaction.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
