Description

Technical Field

[0001] The utility model relates to the technical field of automatic cleaning of reactors, in particular to a built-in cleaning component of a reactor. Background Art

[0002] Reactors are containers for physical or chemical reactions. After use, residues usually remain on the inner wall of the reactor. Therefore, the interior of the reactor needs to be cleaned to prevent the residues from contaminating the reactants and products in the next operation.

[0003] Traditional cleaning methods are mostly manual. After each operation, the manhole cover or kettle lid is opened, and a cleaning technician, armed with a spray gun or injector, reaches into or drills into the reactor to clean the interior. Once cleaning is complete, the technician is removed and the manhole cover or kettle lid is resealed. This cleaning method is labor-intensive and complex, reducing cleaning efficiency. Furthermore, there is a risk of the reactor accidentally initiating agitation after the technician reaches into or drills into the reactor, potentially causing injury and posing a significant safety risk.

[0004] Chinese utility model patent number CN217962557U discloses a rotary cleaning device for a reactor, comprising a spray assembly, the spray assembly comprising a filling pipe fixedly mounted on the upper end of the tank body and a spray pipe internally mounted on the upper end of the tank body, the spray pipe being fixedly connected to the filling pipe, and a spray nozzle distributed at the lower end of the spray pipe for spray cleaning the interior of the tank body. This type of spray nozzle typically uses a high-pressure cleaning nozzle, which consists of a nozzle body, a nozzle tip, and a liquid inlet. The spray body has a threaded fixing portion at one end and a nozzle tip at the other end. The liquid inlet is located on the threaded fixing portion. High-pressure liquid enters through the liquid inlet and forms a high-speed jet through the tiny holes in the nozzle tip, spraying the liquid into fine droplets or mist. However, the interior of the reactor is mostly flocculent solid material, which easily clogs the tiny holes in the nozzle tip, thereby affecting the cleaning effect. Utility Model Content

[0005] In order to solve the technical problem of poor cleaning effect in existing devices, the utility model provides a built-in cleaning component for a reactor with automatic cleaning and good cleaning effect.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] The reactor has a built-in cleaning component, which includes a main body, a fixed part, a water inlet and a spray port. The fixed part is provided with a through hole as a water inlet. The first end of the main body is fixedly connected to the fixed part and communicates with the through hole. The spray port is located at the second end of the main body. The fixed part is installed on the inner wall of the reactor. The main body is a nozzle, and there is at least one nozzle. The cross-section of the internal flow channel of the nozzle gradually decreases from the first end to the second end. The spray port at the second end is flat to form a fan-shaped jet flow.

[0008] Furthermore, the number of nozzles is three.

[0009] Furthermore, the nozzle is arranged in an annular shape on the fixing portion.

[0010] Furthermore, the spraying directions of the spray ports of the nozzles are all different.

[0011] Furthermore, the fixing portion is a disc, and the first end of the nozzle is fixed on a plane on one side of the disc.

[0012] Furthermore, the angle between the central axis of the first end of the nozzle and the plane of one side of the disk is 30° to 90°.

[0013] Furthermore, the angle between the central axis of the first end of the nozzle and the plane of one side of the disk is 90°.

[0014] The beneficial effects of the utility model are:

[0015] 1. The cleaning assembly installed on the inner wall of the reactor can complete the cleaning work without opening the reactor cover, thereby improving the cleaning efficiency and reducing the pollution that may be introduced during the operation. At the same time, it can also avoid the risk of injury to personnel when the cleaning personnel reach into or drill into the reactor to clean and the reactor accidentally starts the stirring program.

[0016] The nozzle is designed to be flat, which can produce a fan-shaped jet flow. Compared with the single-point jet flow, the flat nozzle can effectively avoid material blockage. At the same time, the fan-shaped jet flow helps to cover a wider cleaning area and ensure that the cleaning water flow can be evenly distributed on the entire inner wall of the reactor.

[0017] The design of the internal flow channel cross-section gradually decreasing from the first end to the second end helps to increase the injection pressure, enhance the cleaning ability, and can effectively disperse the flocs formed by high-concentration materials.

[0018] 2. Setting three nozzles can increase the number of injection points, making the cleaning process more comprehensive and reducing the existence of dead corners.

[0019] 3. The annular arrangement of the nozzles ensures a relatively concentrated spray range. Not only does the jet flow create a certain coverage area within the reactor, but it also enhances local cleaning efforts, especially in areas requiring focused cleaning. The annular arrangement of the nozzles provides excellent structural balance. Due to the even distribution of the nozzles, the overall device maintains good stability, avoiding deflection or rotational imbalance caused by unilateral spraying.

[0020] 4. Different spray directions can further improve the coverage of the cleaning liquid, ensuring that all areas on the inner wall of the reactor can be effectively cleaned, and preventing incomplete cleaning caused by a single spray angle.

[0021] 5. The disc shape of the fixing part is convenient for installation and disassembly, and it is easy to install on the reactor through the flange.

[0022] 6. The angle between the nozzle and the disc is designed to be between 30° and 90°. The spray angle can be adjusted according to actual needs to meet the cleaning requirements of different positions of the reactor and improve cleaning efficiency.

[0023] 7. Vertical jetting can directly impact the inner wall of the reactor, which means that the jet flow can reach the inner wall surface in the shortest distance, increasing the instantaneous impact force of the jet flow in contact with the inner wall, which helps to remove stubborn residues.

For example, "fixation" can mean fixed connection, detachable connection, or integration; it can be mechanical connection or electrical connection; it can be direct connection or indirect connection through an intermediate medium; it can mean internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0031] Reference Figures 1 to 2 , the utility model provides a built-in cleaning component for a reactor.

[0032] In some embodiments, the reactor has a built-in cleaning component, including a main body, a fixed part 1, a water inlet 2 and a spray port 4. A through hole is opened on the fixed part 1 as the water inlet 2. The first end of the main body is fixedly connected to the fixed part 1 and communicated with the through hole. The spray port 4 is located at the second end of the main body. The fixed part 1 is installed on the inner wall of the reactor. The main body is a nozzle 3. There are at least one nozzle 3. The cross-section of the internal flow channel of the nozzle 3 gradually decreases from the first end to the second end. The spray port 4 at the second end is flat to form a fan-shaped jet flow.

[0033] This solution achieves all-round cleaning by installing multiple cleaning components on the top inner wall and side inner wall of the reactor. The water inlet 2 of the cleaning component is connected to the water inlet pipe, and the water inlet pipe is provided with a component electrically connected to the automatic control system. The existing automatic control system controls the input of the cleaning water flow to the cleaning component, and utilizes the powerful water flow impact of the jet port 4 to clean the materials inside the reactor. At the same time, it can also effectively disperse the flocs formed by high-concentration materials, further facilitating the discharge of materials. The jet port 4 is designed to be flat-mouthed and can produce a fan-shaped jet flow. Compared with a single-point jet flow, the flat-mouthed jet port 4 can effectively avoid material blockage. This cleaning component that combines cleaning and material dispersion significantly improves the cleanliness and discharge efficiency of the reactor.

[0034] The fixing part 1 is preferably a disc, which can be fixed between two flanges, so that it can be easily and conveniently installed on the reactor. The disc can be rotated and adjusted 360 degrees to meet the cleaning requirements of different parts of the reactor. The fixing part 1 can also adopt a tubular structure, which is directly fixed on the top inner wall or side inner wall of the reactor by welding or other means. The tubular structure can be a straight tube or a curved tube, so that it can be adjusted according to the requirements of the injection angle. The fixing part 1 can also adopt a threaded fixing part, which is directly screwed into the matching threaded interface on the top inner wall or side inner wall of the reactor. This method is easy to install and is suitable for occasions that require frequent disassembly and assembly. The fixing part 1 can also adopt a bracket structure, which is fixed on the top inner wall or side inner wall of the reactor by welding, bolts or other means. The bracket can provide multiple fixing points to enhance the overall stability.

[0035] The injection port 4 is designed to be flat-mouthed, which can produce a fan-shaped jet flow. Compared with the single-point jet flow, the flat-mouthed injection port 4 can effectively avoid material blockage. The fan-shaped jet flow also helps to cover a wider cleaning area, ensuring that the cleaning water flow can be evenly distributed on the entire inner wall of the reactor.

[0036] In some embodiments, there are three nozzles 3. The three nozzles 3 can be arranged in parallel and spaced apart, or in a ring, or in other scattered arrangements, and the arrangement is not particularly limited here.

[0037] In some embodiments, the nozzles 3 are arranged in a ring on the fixed portion 1. This circular arrangement of the nozzles 3 ensures a relatively concentrated spray range, not only ensuring that the jet streams have a certain coverage area within the reactor, but also enhancing localized cleaning efforts, particularly in areas requiring focused cleaning. The circular arrangement of the nozzles 3 provides good structural balance. Due to the even distribution of the nozzles 3, the overall device maintains good stability, avoiding deflection or rotational imbalance caused by unilateral spraying.

[0038] In some embodiments, the spraying directions of the nozzles 4 of the nozzles 3 are all different. Different spraying directions can further improve the coverage of the cleaning liquid, ensuring that all areas on the inner wall of the reactor are effectively cleaned, and preventing incomplete cleaning caused by a single spray angle.

[0039] In some embodiments, the fixing portion 1 is a disc, and the first end of the nozzle 3 is fixed to a flat surface on one side of the disc. The disc is simple in structure and can be fixed to the top or side inner wall of the reactor with a flange. The disc can be rotated 360 degrees to meet the cleaning requirements of different parts of the reactor. It also provides a stable structure and good sealing performance.

[0040] In some embodiments, the angle between the central axis of the first end of the nozzle 3 and the plane of one side of the disk is 30° to 90°. The angle between the nozzle 3 and the disk is designed to be between 30° and 90°, and the spray angle can be adjusted according to actual needs to meet the cleaning requirements of different positions in the reactor and improve cleaning efficiency.

[0041] In some embodiments, the central axis of the first end of the nozzle 3 forms an angle of 90° with the plane of one side of the disk. Vertical jetting can directly impact the inner wall of the reactor, meaning the jet reaches the inner wall surface with the shortest distance possible, increasing the instantaneous impact force of the jet upon contact with the inner wall and helping to remove stubborn residues.
