Description

Technical Field

[0001] This utility model relates to the field of reaction vessels, and more specifically, to a reaction vessel that is easy to clean. Background Technology

[0002] In industrial production processes such as chemical, pharmaceutical, and food processing, reaction vessels are key equipment for chemical reactions, material mixing, and other operations.

[0003] Chinese Patent Announcement No. CN215277342U provides a reaction vessel, which includes a vessel body, a flow-dispersing device disposed inside the vessel body, and a stirring device. The flow-dispersing device includes: a flow-dispersing cylinder, a few flow-dispersing rings horizontally disposed inside the flow-dispersing cylinder, and a number of mounting components located at the top and bottom of the flow-dispersing cylinder. The flow-dispersing rings have different diameters and are arranged in a regular sequence along the vertical direction of the flow-dispersing cylinder according to their diameters.

[0004] However, the aforementioned patents can only achieve simple stirring functions, making it difficult to ensure that the materials are fully mixed in the reactor. For some materials with high viscosity or that easily adhere to the reactor wall, they cannot be effectively scraped off to participate in the reaction, resulting in incomplete reaction, inconsistent product quality, material waste, and increased production costs. In addition, in the discharge filtration stage, existing reactor filtration devices usually use fixed-installed filter screens. Once the filter screen is clogged or damaged, the cleaning and replacement process is very cumbersome, often requiring the use of multiple tools and spending a lot of time disassembling related parts. This not only increases the labor intensity of operators but also leads to long-term equipment downtime.

[0005] Therefore, a reaction vessel that is easy to clean is proposed to address the above problems. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a reaction vessel that is easy to clean.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A reaction vessel that is easy to clean includes a reaction vessel body, an inlet at the top of the reaction vessel body, an outlet pipe fixedly connected to the bottom of the reaction vessel body, a mounting base fixedly connected to the outer wall of the outlet pipe, the mounting base being fixedly connected to the bottom of the reaction vessel body, and six sliding rods slidably connected inside the mounting base, the six sliding rods being arranged in an equidistant circular array inside the mounting base, with a limit block and a fixing block fixedly connected to both ends of each sliding rod, respectively.

[0009] Furthermore, a first spring is sleeved on the outside of the sliding rod, and the first spring is located between the fixed block and the mounting base. Both the limiting block and the fixed block are arc-shaped structures.

[0010] Furthermore, a sliding cover is slidably connected to the outside of the mounting base, and a second spring is sleeved on the outer wall of the mounting base. The second spring is located between the mounting base and the sliding cover, and its two ends are fixedly connected to the outside of the mounting base and the inner wall of the sliding cover, respectively.

[0011] Furthermore, a connecting pipe is slidably connected inside the mounting base, and an arc-shaped groove is formed on the outer wall of the connecting pipe, with the limiting block engaging inside the arc-shaped groove.

[0012] Furthermore, a filter screen is installed on one side of the connecting pipe, the filter screen is located between the discharge pipe and the connecting pipe, and four locking blocks are fixedly connected to the outer wall of the filter screen. A groove corresponding to the four locking blocks is opened on one side of the connecting pipe.

[0013] Furthermore, a rotating frame is rotatably connected inside the reactor body, scrapers are fixedly connected to both sides of the rotating frame, and a stirring shaft is rotatably connected to the middle of the rotating frame.

[0014] Furthermore, bevel gears are fixedly connected to one end of the stirring shaft and the rotating frame outside the reactor body and above the reactor body, respectively. A motor is fixedly connected to the top of the reactor body, and the output end of the motor is fixedly connected to the top of the stirring shaft.

[0015] Furthermore, a support leg is fixedly connected to the lower part of the outer wall of the reactor body.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this solution, when the filter screen needs to be cleaned or replaced, simply move the sliding cover to release its blockage on the fixed block, so that the limiting block can be disengaged from the arc groove and the connecting pipe and filter screen can be easily removed. The operation process does not require complicated tools, which greatly shortens the maintenance time and reduces labor costs. At the same time, the filter screen adopts the snap-fit ​​design of the snap-fit ​​block and the groove body, which facilitates quick disassembly and installation. Users can also flexibly replace different specifications of filter screens according to different material characteristics and production needs, thereby enhancing the applicability of the equipment.

[0018] (2) In this scheme, the motor drives the stirring shaft to rotate, and the rotating frame and scraper are driven to operate synchronously through the bevel gear transmission. The stirring shaft realizes strong stirring of the material, and the scraper scrapes off the material attached to the inner wall of the reactor, so as to promote the full mixing of the material and effectively avoid the accumulation of material. This not only improves the reaction rate, but also ensures that the reaction is fully carried out, and improves the product quality and yield.

[0019] (3) In this solution, during the operation and discharge of the reactor, the sealing effect of the sliding cover on the fixed block ensures the stability of the sliding rod and keeps the limit block locked in the arc groove, ensuring that the position of the connecting pipe and the filter screen is fixed. Even when faced with complex working conditions such as material impact and equipment vibration, the filter screen will not loosen or shift, and will continuously and stably filter the material, effectively intercept impurities, ensure the purity of the discharge, and avoid product quality decline and equipment failure due to filter screen problems.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In some embodiments, please refer to Figure 1-6 A convenient-to-clean reaction vessel includes a reaction vessel body 1. An inlet 11 is provided at the top of the reaction vessel body 1. A discharge pipe 18 is fixedly connected to the bottom of the reaction vessel body 1. A mounting base 19 is fixedly connected to the outer wall of the discharge pipe 18. The mounting base 19 is fixedly connected to the bottom of the reaction vessel body 1. Six sliding rods 2 are slidably connected inside the mounting base 19, arranged in an equidistant circular array. Limiting blocks 21 and fixing blocks 23 are fixedly connected to both ends of each sliding rod 2. A first spring 22 is sleeved on the outside of each sliding rod 2, located between the fixing block 23 and the mounting base 19. Both the limiting block 21 and the fixing block 23 are arc-shaped structures. A sliding cover 24 is slidably connected to the outside of the mounting base 19. A second spring 25 is sleeved on the outer wall of the mounting base 19, located between the mounting base 19 and the sliding cover 24. The two ends of the second spring 25 are fixedly connected to the outside of the mounting base 19 and the inner wall of the sliding cover 24, respectively. A connecting pipe 26 is slidably connected inside the mounting base 19. An arc-shaped groove 27 is formed on the outer wall of the connecting pipe 26, and a limiting block 21 is engaged inside the arc-shaped groove 27. A filter screen 28 is installed on one side of the connecting pipe 26, located between the discharge pipe 18 and the connecting pipe 26. Four locking blocks 29 are fixedly connected to the outer wall of the filter screen 28, and a groove corresponding to the four locking blocks 29 is formed on one side of the connecting pipe 26.

[0032] In this embodiment, the feed inlet 11 is used for material input. The sealing design of the sliding cover 24 on the fixed block 23 forms a physical barrier, firmly restricting the fixed block 23 inside the mounting base 19, preventing the sliding rod 2 from moving freely. This ensures that the limiting block 21 is continuously and securely engaged in the arc-shaped groove 27. Even if the reactor faces complex operating conditions such as strong vibration and material impact during operation, the connecting pipe 26 and the filter screen 28 will not loosen or shift, ensuring stable operation of the filtration system, effectively intercepting impurities in the material, ensuring the purity of the output, and improving product quality.

[0033] To avoid problems such as filter failure and material leakage caused by the limit block 21 disengaging from the arc groove 27 and the filter screen 28 becoming loose, the probability of sudden equipment failure is reduced, the time and economic losses caused by downtime for maintenance are minimized, and the continuity and stability of production are improved.

[0034] The sealing function of the sliding cover 24 fixes the relative positions of the components, reducing friction and wear caused by mutual displacement between components, extending the service life of key components such as the sliding rod 2 and connecting pipe 26. At the same time, the stable structure reduces abnormal wear during equipment operation, lowers the overall maintenance frequency and cost, and improves the economic benefits of the enterprise.

[0035] Because the sliding cover 24 blocks the fixing block 23, when the filter screen 28 needs cleaning or replacement, the operator only needs to observe the state of the sliding cover 24 to quickly determine the engagement status of the limit block 21 and the arc groove 27. This eliminates the need for complex testing procedures, simplifies the pre-maintenance inspection process, and improves maintenance efficiency.

[0036] During reactor operation, the sliding cover 24 eliminates the risk of material leakage due to loose components, prevents operators from coming into contact with high-temperature, corrosive, or toxic materials, and ensures personnel safety and health. Even in extreme situations such as sudden equipment vibration, it ensures the structural stability of the filtration system and prevents safety accidents.

[0037] The clear and stable structural design makes the maintenance of filter screen 28 more standardized and safer. When disassembling and installing filter screen 28, operators only need to follow the steps to slide the sliding cover 24 onto the surface of the mounting base 19 and release the blockage of the fixing block 23. This easily releases the engagement between the limiting block 21 and the arc-shaped groove 27, eliminating concerns about the operational risks caused by accidental detachment or displacement of parts. This reduces the skill requirements for operators, minimizes equipment damage and safety accidents caused by improper operation, and improves overall production safety. When cleaning or replacing filter screen 28, operators only need to simply slide the sliding cover 24 to quickly release the engagement between the limiting block 21 and the arc-shaped groove 27. Compared to traditional reactors that require complex tools or multiple steps to disassemble filter screen 28, this significantly shortens maintenance time and improves work efficiency. Especially in large-scale continuous production scenarios, it effectively reduces equipment downtime and improves the company's production efficiency.

[0038] Eliminating the need for laborious disassembly or installation of components reduces the workload for operators and minimizes potential damage to the equipment caused by frequent and forceful handling, thereby extending the equipment's lifespan and achieving efficient collaboration between equipment and human resources.

[0039] In some embodiments, please refer to Figure 1-6 A reaction vessel designed for easy cleaning includes a rotating frame 13 rotatably connected inside the reaction vessel body 1. Scrapers 14 are fixedly connected to both sides of the rotating frame 13. A stirring shaft 15 is rotatably connected to the center of the rotating frame 13. Bevel gears 16 are fixedly connected to the stirring shaft 15, the rotating frame 13 at one end outside the reaction vessel body 1, and above the reaction vessel body 1. The upper and lower bevel gears 16 mesh with the left and right bevel gears 16, respectively. A motor 17 is fixedly connected to the top of the reaction vessel body 1, and the output end of the motor 17 is fixedly connected to the top of the stirring shaft 15. Support legs 12 are fixedly connected to the lower part of the outer wall of the reaction vessel body 1.

[0040] In this embodiment, the motor 17 drives the stirring shaft 15 to rotate, which, through the transmission of the bevel gear 16, drives the rotating frame 13 to rotate synchronously. The stirring shaft 15 achieves thorough stirring of the materials in the reactor. During the rotation, the scrapers 14 on both sides of the rotating frame 13 scrape off the materials adhering to the inner wall of the reactor, allowing the materials to re-participate in the mixing, preventing the materials from accumulating on the reactor wall, ensuring uniform mixing, improving the reaction rate and completeness, and increasing product quality and yield.

[0041] After each reaction, scraper 14 can perform preliminary cleaning of the inner wall of the reactor, scraping away residual materials and reducing the difficulty and workload of manual cleaning. Combined with the convenient cleaning design of filter screen 28, it greatly reduces the overall maintenance cost of the equipment, improves the efficiency and turnover speed of the equipment, and allows the reactor to be put into the next round of production more quickly.

[0042] The support legs 12 located on the lower outer wall of the reactor body 1 provide stable support for the entire device, ensuring the reactor remains stable during operation. This effectively distributes the weight of the equipment and the forces generated during operation, reducing the impact of equipment shaking on internal stirring, filtration, and other systems, thus guaranteeing stable operation and extending the equipment's service life.

[0043] Working Principle: After the motor 17 starts, its output power drives the stirring shaft 15 to rotate. The bevel gear 16 located at one end of the stirring shaft 15 outside the reactor body 1 transmits power to the bevel gear 16 located at one end of the rotating frame 13 outside the reactor body 1 through gear transmission, thereby causing the rotating frame 13 to start rotating. The stirring shaft 15 stirs the materials inside the reactor body 1. At the same time, the scrapers 14 fixedly connected to both sides of the rotating frame 13 scrape the inner wall of the reactor body 1 as the rotating frame 13 rotates. The stirring of the stirring shaft 15 and the scraping of the scrapers 14 work together to ensure that the materials are fully mixed, improving the uniformity and efficiency of the reaction and allowing the chemical reaction to proceed more completely. On the other hand, it scrapes off the materials adhering to the inner wall of the reactor, preventing the materials from accumulating on the reactor wall, avoiding affecting the reaction effect and causing material waste.

[0044] After the reaction is complete, the material is discharged through the discharge pipe 18 below the reactor body 1. During the discharge process, the filter screen 28 on the connecting pipe 26 filters the material, intercepting impurities and particles to ensure that the purity of the discharged material meets production requirements. At this time, the sliding cover 24 seals the fixing block 23 inside the mounting base 19, stabilizing the sliding rod 2. The limiting block 21 is always engaged in the arc-shaped groove 27 on the outer wall of the connecting pipe 26, ensuring that the connecting pipe 26 and the filter screen 28 are fixed in position, maintaining the stable operation of the filtration system, preventing the filter screen 28 from loosening or shifting under the impact of the material, and ensuring the filtration effect.

[0045] When the filter screen 28 needs cleaning or replacement, the operator moves the sliding cover 24 to slide it on the surface of the mounting base 19, releasing the blockage of the fixing block 23. At this time, the sliding rod 2 is no longer restricted by the sliding cover 24. Under the action of external operating force, it overcomes the first spring 22 and drives the limiting block 21 to move upward, causing the limiting block 21 to disengage from the arc groove 27. Thus, the connecting pipe 26 can be removed from the mounting base 19. After the connecting pipe 26 is removed, the locking block 29 on the outer wall of the filter screen 28 is engaged with the groove on one side of the connecting pipe 26. With proper coordination, the filter screen 28 can be easily removed from the connecting pipe 26 for cleaning or replacement. After cleaning or replacement, the filter screen 28 is reattached to the connecting pipe 26, and the connecting pipe 26 is placed into the mounting base 19. The limiting block 21 is aligned with the arc groove 27. The sliding cover 24 is released, and under the action of the second spring 25, the sliding cover 24 is reset, and the fixing block 23 is resealed. The limiting block 21 is then inserted into the arc groove 27, completing the installation and fixing of the connecting pipe 26 and the filter screen 28, and restoring the reactor to normal operating condition.

[0046] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
