Technical Field

[0001] This utility model belongs to the field of chemical reaction equipment, and in particular relates to a reaction vessel with a self-cleaning function. Background Technology

[0002] With the rapid development of chemical industry, pharmaceutical engineering, new material research and development and biotechnology, the reactor, as the core equipment for realizing various chemical reactions, synthesis processes and material preparation processes, has seen its application scope continuously expand and its usage frequency significantly increase. This has also placed increasingly stringent requirements on the performance, safety and intelligence level of the equipment.

[0003] However, most reactors currently only have basic heating, stirring and reaction control functions. After the reaction is completed, the inner wall of the reactor and the stirring components are prone to residual reactants, forming scale. In order to avoid these residues affecting the purity and quality of subsequent products, a lot of time is required for manual cleaning, which increases the labor intensity of personnel and leads to a longer production cycle.

[0004] Therefore, a reaction vessel with self-cleaning function is particularly needed to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing reaction vessels that lack self-cleaning ability, rely on manual cleaning, have high labor intensity and easily prolong the production cycle, this utility model provides a reaction vessel with self-cleaning function.

The support is a load-bearing structure with multiple rollers rotatably mounted on its upper part. The reaction vessel body is placed on the upper part of the support, and its outer wall is in contact with the wheel surfaces of the multiple rollers. The controller is installed on the left side of the reaction vessel body, and the stirring and scraping assembly is set on the reaction vessel body.

The connecting ring is installed at one end of the stirring paddle, and two symmetrically distributed scrapers are fixed to its outer periphery. The scraping surfaces of the scrapers are in contact with the inner wall of the reactor body.

[0008] Furthermore, the water spray assembly includes a bidirectional nozzle, an electric rotary disc, a vision monitoring module, and a protective shell.

[0020] Example: A reaction vessel with self-cleaning function, such as Figures 1-6 As shown, the reactor includes a support 1, rollers 2, a reactor body 3, a controller 5, and a stirring and scraping assembly. The support 1 is a load-bearing structure with eight rollers 2 rotatably mounted on its upper part. The reactor body 3 is placed on the upper part of the support 1, and its outer wall contacts the wheel surfaces of the eight rollers 2. The reactor body 3 has two annular plates at both the front and rear, and a limiting groove is formed between adjacent annular plates. The four rollers 2 on the same side are embedded in the limiting grooves on the corresponding sides, which can effectively prevent the reactor body 3 from axially slipping off when rotating on the support 1. The controller 5 is fixed to the left front position of the reactor body 3 by bolts and adopts a programmable logic controller, model Siemens S7-1215CDC / DC / DC, which has multi-output control function and can centrally control multiple electrical components, including stirring and scraping. The components are mounted on the reactor body 3 and include a drain pipe 4, a mounting plate 11, a connecting pump 12, a water supply pipe 13, a rotating pipe 14, a water spray assembly, and a transmission assembly. The drain pipe 4 is fixed to the rear left side of the reactor body 3 by bolts. The mounting plate 11 is fixed to the front of the reactor body 3 by bolts. The connecting pump 12 is fixed to the mounting plate 11 by bolts. The water outlet of the connecting pump 12 passes through the mounting plate 11 and extends into the reactor body 3. The connecting pump 12 is electrically connected to the controller 5. The water supply pipe 13 is fixedly connected to the water outlet of the connecting pump 12. The rear end of the water supply pipe 13 is rotatably mounted on the rotating pipe 14 through a limiting structure formed by an annular block and an annular groove. The water spray assembly is mounted on the rotating pipe 14. The transmission assembly is located between the water supply pipe 13 and the rotating pipe 14.

[0021] like Figure 3 and Figure 4 As shown, the stirring and scraping assembly includes a connecting plate 6, a servo motor 7, a stirring paddle 8, a connecting ring 9, and scraper rods 10. The connecting plate 6 is fixed to the center of the front part of the reactor body 3 by bolts. The servo motor 7 is fixed to the front part of the connecting plate 6 by bolts, and its output shaft extends horizontally backward and passes through the connecting plate 6 to the inside of the reactor body 3. The servo motor 7 is electrically connected to the controller 5. The stirring paddle 8 is fixedly connected to the output shaft of the servo motor 7 by a coupling. The connecting ring 9 is fixed to the rear end of the stirring paddle 8 by bolts. Two symmetrically distributed scraper rods 10 are fixedly connected to the outer periphery of the connecting ring 9. The scraping surface of the scraper rods 10 is in contact with the inner wall of the reactor body 3.

[0022] like Figure 5 and Figure 6 As shown, the water spray assembly includes a bidirectional nozzle 15, an electric turntable 16, a vision monitoring module 17, and a protective shell 18. The electric turntable 16 is fixed to the rotating tube 14 by bolts and has a circular opening. The bidirectional nozzle 15 is fixed to the rotating end of the electric turntable 16 by bolts. The water outlet end of the rotating tube 14 passes through the circular opening of the electric turntable 16 and is connected to the bidirectional nozzle 15 by a rotary joint. The vision monitoring module 17 is fixed to the top of the bidirectional nozzle 15 by bolts and can collect images of the cleanliness status inside the reactor body 3 in real time. Both the electric turntable 16 and the vision monitoring module 17 are electrically connected to the controller 5. The protective shell 18 is fixedly connected to the top of the bidirectional nozzle 15 and covers the outside of the vision monitoring module 17 to provide sealing and protection. The protective shell 18 is made of a transparent material, such as an acrylic sheet.

[0023] like Figure 5 and Figure 6 As shown, the transmission assembly includes a mounting bracket 19, a motor 20, a gear ring 21, and a gear 22. The mounting bracket 19 is fixed to the rear end of the water supply pipe 13 by bolts. The rotating pipe 14 is located behind the mounting bracket 19. The motor 20 is fixed to the top of the mounting bracket 19 by bolts, and its output shaft extends horizontally backward. The motor 20 is electrically connected to the controller 5. The gear ring 21 is fixedly connected to the outer periphery of the front end of the rotating pipe 14. The gear 22 is fixedly connected to the output shaft of the motor 20 and is located above the gear ring 21, meshing with it. The gear 22 and the gear ring 21 have the same axial thickness. The size of the gear ring 21 is larger than that of the gear 22. The number of teeth of the gear ring 21 is twice the number of teeth of the gear 22. Based on this tooth ratio, when the gear 22 rotates one revolution, the gear ring 21 drives the rotating pipe 14 to rotate half a revolution. When the gear 22 rotates two revolutions, the rotating pipe 14 completes one revolution, realizing speed reduction transmission and ensuring that the rotating pipe 14 rotates smoothly.

[0024] After the chemical reaction is completed and the material inside the reactor body 3 is emptied, the external clean water source is connected to the water inlet at the front of the connecting pump 12. The operator starts the self-cleaning mode through the controller 5. The controller 5 then turns on the connecting pump 12. The clean water is transported to the rotating pipe 14 through the water pipe 13 under the action of the connecting pump 12, and then sprayed at high pressure onto the inner wall of the reactor body 3 by the bidirectional nozzle 15 to start the water flushing process of the residual material. At the same time, the controller 5 drives the electric turntable 16 to start running. The electric turntable 16 drives the bidirectional nozzle 15 to rotate in its original position, so that the spray direction can be dynamically changed, effectively enhancing the coverage of the rinsing. While the bidirectional nozzle 15 is rotating and spraying, the motor 20 is started under the command of the controller 5. The output shaft of the motor 20 drives the gear 22 to rotate, so that the gear 22 meshes with the gear ring 21, driving the gear ring 21 to drive the rotating tube 14 to rotate smoothly, thereby driving the bidirectional nozzle 15 to perform a spiral motion along the axial direction. Through this spiral motion, the bidirectional nozzle 15 can achieve a comprehensive rinsing of the inner wall of the reactor body 3, and can also effectively rinse the surface of the stirring paddle 8. In addition, the servo motor 7 starts at low speed under the control of the controller 5. The output shaft of the servo motor 7 drives the stirring paddle 8 to rotate. The connecting ring 9 at the rear end of the stirring paddle 8 rotates synchronously, driving the scraper 10 to run along the trajectory that fits the inner wall of the reactor body 3. During operation, the scraper 10 can mechanically scrape off the scale adhering to the inner wall of the reactor body 3, which works synergistically with the high-pressure water rinsing of the bidirectional nozzle 15 to further improve the cleaning effect. During the rinsing process, the visual monitoring module 17 collects images of the cleanliness status inside the reactor body 3 in real time and transmits them to the controller 5 in real time. By observing the images collected on the controller 5, the degree of removal of residues on the inner wall of the reactor body 3 can be determined. Once the removal of residue from the inner wall of the reactor body 3 is deemed satisfactory, the controller 5 shuts off the connecting pump 12, electric turntable 16, motor 20, and servo motor 7, and enters the drainage stage. By adjusting the angle of the reactor body 3, it is rotated to a suitable position where the drain outlet of the drain pipe 4 faces downwards. The drain pipe 4 is then opened, and the wastewater is discharged through the drain pipe 4 of the reactor body 3, thus completing the entire self-cleaning process.
