Description

Technical Field

[0001] This utility model relates to the field of centrifugal transfer reactors, and in particular to a crude centrifugal transfer reactor for the preparation of cytosine. Background Technology

[0002] Centrifugal transfer tanks are devices used in centrifugal separation processes to transfer, store, and pre-treat materials. They have functions such as stirring, temperature control, and liquid level regulation. They can pre-treat materials to provide a stable and uniform feed for centrifugal separation. Crude cytosine preparation uses crude cytosine transfer tanks because they can temporarily store crude products after the reaction vessel discharge, acting as a buffer to ensure production continuity. Even if the centrifuge malfunctions, it will not affect the upstream reaction. The stirring device inside the transfer tank can uniformly mix crude products with possible uneven concentrations and particle sizes, which is beneficial for efficient separation in subsequent centrifuges, improving product purity and quality. The temperature control device can also regulate the temperature to prevent the temperature-sensitive cytosine from deteriorating and degrading, thereby increasing the yield. Furthermore, according to the centrifuge feed requirements, the material flow rate and pressure can be precisely adjusted to optimize the centrifuge working conditions, reduce equipment wear, extend its service life, and improve overall production efficiency.

[0003] The existing crude cytosine preparation centrifugal transfer vessel consists of a vessel body, stirring, heating and cooling system, inlet and outlet ports, and control system. The crude product from the reactor enters the transfer vessel through the inlet for temporary storage and buffering, ensuring a stable production process and preventing downstream equipment problems from interfering with upstream processes. The stirring device uses a motor to drive the blades to rotate, ensuring uniform mixing of the crude product and providing a uniform feed for centrifugal separation. Depending on the process and material characteristics, the material temperature is precisely controlled by hot and cold media in the jacket or coil to prevent cytosine decomposition or crystallization. The liquid level sensor transmits the liquid level signal to the control system, which controls the inlet and outlet valves to maintain a reasonable liquid level. If necessary, the discharge flow rate is adjusted or inert gas is introduced to regulate the pressure inside the vessel, ensuring that each step operates under appropriate pressure.

[0004] In the cytosine preparation process, the crude product centrifuge transfer vessel plays a crucial role in material transfer and pretreatment. However, a significant problem has emerged in the current equipment: due to the characteristics of the inner wall material, some material adsorbs or undergoes subtle reactions with the crude cytosine material during prolonged contact. This not only leads to material loss but also causes deviations in material composition, resulting in errors that are difficult to ignore during production. For example, after multiple production cycles, the purity of the product deviates from the expected value. These errors seriously affect the efficient operation of the crude cytosine preparation centrifuge transfer vessel, hindering the improvement of overall production efficiency and product quality. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a crude cytosine preparation centrifuge transfer vessel, which aims to improve the problem that some material on the inner wall of the vessel may cause errors in the production process during equipment use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a centrifugal transfer vessel for preparing crude cytosine, comprising a tank body, an inlet pipe fixedly connected to the top of the tank body, a drive assembly provided at the top of the tank body, a rotating shaft rotatably connected inside the tank body, a support frame fixedly connected inside the tank body, multiple fixing blocks fixedly connected to the outer wall of the rotating shaft, multiple stirring blades fixedly connected to the outer wall of each fixing block, and multiple scraping assemblies provided on the outer wall of the rotating shaft;

[0007] Each of the scraping components includes a fixing strip one, a connecting strip, multiple plastic scrapers, and a fixing strip two. One end of each fixing strip one is fixedly connected to the outer wall of the rotating shaft. One side of each connecting strip is fixedly connected to one end of the fixing strip one. One side of each plastic scraper is fixedly connected to both sides of the fixing strip two. One end of each fixing strip two is fixedly connected to the outer wall of the rotating shaft.

[0008] As a further description of the above technical solution:

[0009] The drive assembly includes a protective box and a motor. The bottom of the protective box is fixedly connected to the top of the tank, the outer wall of the motor is fixedly connected to the inside of the protective box, and the output end of the motor is connected to the top of the rotating shaft.

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

[0011] A discharge pipe is fixedly connected to the bottom of the tank, and a transport pipe is fixedly connected to the bottom end of the discharge pipe.

[0012] As a further description of the above technical solution:

[0013] A diversion pipe is fixedly connected to the outer wall of the transport pipe, and a valve is fixedly connected inside the diversion pipe.

[0014] As a further description of the above technical solution:

[0015] A return pump is fixedly connected to one end of the shunt pipe. The input end of the return pump is connected to one end of the shunt pipe, and the output end of the return pump is fixedly connected to the return pipe.

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

[0017] One end of the reflux pipe is fixedly connected to the top of the tank, and the reflux pipe and the discharge pipe are arranged in a parallel array outside the connecting strip.

[0018] As a further description of the above technical solution:

[0019] The stirring blades are arranged in a ring array and fixedly connected to the outer wall of the fixed block, and the fixing strips are arranged in a ring array and fixedly connected to the outer wall of the rotating shaft.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the motor is first started to drive the stirring blade to rotate, which causes the fixing strip to rotate. Then, the plastic scrapers on both sides of the connecting strip begin to scrape the inner wall of the tank, so that all the material on the inner wall of the tube is scraped off. This achieves the effect of scraping off the material remaining on the inner wall while stirring during equipment use, avoiding the problem of some material remaining on the inner wall of the tank during equipment use, which may cause errors in the production process. This improves the efficiency of the centrifugal transfer vessel for crude cytosine preparation.

[0022] 2. In this utility model, when the centrifuge experiences uneven feeding or poor material separation, the valve is opened to allow the material to enter the diversion pipe. At the same time, the reflux pump is started to draw the material into the reflux pipe, and then it returns to the tank to wait for the centrifuge to be repaired. This achieves the effect of temporarily storing the material in the transfer vessel when the centrifuge malfunctions during equipment use, avoiding the problem of the material still being supplied when the centrifuge malfunctions, which would lead to maintenance difficulties. This improves the practicality of the crude cytosine preparation centrifuge transfer vessel. Attached Figure Description

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.

[0029] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a centrifugal transfer vessel for preparing crude cytosine, comprising a tank body 1, a feed pipe 2 fixedly connected to the top of the tank body 1 for introducing materials, a drive assembly provided at the top of the tank body 1 for driving stirring blades 8 to agitate, a rotating shaft 5 rotatably connected inside the tank body 1 for driving stirring blades 8 to agitate, a support frame 6 fixedly connected inside the tank body 1 for supporting the rotating shaft 5, multiple fixing blocks 7 fixedly connected to the outer wall of the rotating shaft 5 for fixing stirring blades 8, multiple stirring blades 8 fixedly connected to the outer wall of each fixing block 7 for agitating materials, and multiple scraping assemblies provided on the outer wall of the rotating shaft 5 for scraping off materials adhering to the inner wall;

[0030] Each scraping assembly includes a fixing strip 9, a connecting strip 10, multiple plastic scrapers 11, and a fixing strip 12. One end of each fixing strip 9 is fixedly connected to the outer wall of the rotating shaft 5 to fix the connecting strip 10. One side of each connecting strip 10 is fixedly connected to one end of the fixing strip 9 to connect the plastic scrapers 11. One side of each plastic scraper 11 is fixedly connected to both sides of the fixing strip 12 to scrape off the material remaining on the inner wall. One end of each fixing strip 12 is fixedly connected to the outer wall of the rotating shaft 5 to fix the connecting strip 10. The drive assembly includes a protective box 3 and a motor 4. The bottom of the protective box 3 is fixedly connected to the top of the tank 1 to protect the motor 4. The outer wall of the motor 4 is fixedly connected to the inside of the protective box 3 to drive the stirring blade 8 and the plastic scrapers 11. The output end of the motor 4 is connected to the top of the rotating shaft 5.

[0031] Specifically, when the equipment is put into use, the operator first starts the motor 4, which drives the rotating shaft 5 to start rotating, and then drives the stirring blade 8 connected to it to rotate together. At the same time, the fixing strip 9 connected to the rotating shaft 5 also starts to rotate. As the fixing strip 9 rotates, the plastic scrapers 11 installed on both sides of the connecting strip 10 are also driven to scrape the inner wall of the tank 1, leaving no corner with material attached, and ensuring that all the residual material on the inner wall of the tank 1 can be scraped off.

[0032] Reference Figure 3A discharge pipe 13 is fixedly connected to the bottom of the tank 1 for discharging materials. A transport pipe 14 is fixedly connected to the bottom of the discharge pipe 13 for transporting materials. A diversion pipe 15 is fixedly connected to the outer wall of the transport pipe 14 for diverting materials. A valve 16 is fixedly connected inside the diversion pipe 15 to control the opening and closing of the diversion pipe 15. A return pump 17 is fixedly connected to one end of the diversion pipe 15 to drive the material back. The input end of the return pump 17 is connected to one end of the diversion pipe 15. A return pipe 18 is fixedly connected to the output end of the return pump 17 for guiding the material back to the tank 1. One end of the return pipe 18 is fixedly connected to the top of the tank 1. The return pipe 18 and the discharge pipe 13 are arranged in a parallel array outside the connecting strip 10. The stirring blades 8 are arranged in a ring array and fixedly connected to the outer wall of the fixing block 7. The fixing strips 9 are arranged in a ring array and fixedly connected to the outer wall of the rotating shaft 5.

[0033] Specifically, during the operation of the crude cytosine preparation centrifuge transfer vessel, when the operator notices uneven feeding in the centrifuge, the operator opens valve 16. At this time, valve 16 allows the material that failed to enter the centrifuge for effective separation to flow smoothly into the diversion pipe 15. Simultaneously, the operator starts the reflux pump 17. Under the strong drive of the reflux pump 17, the material continuously enters the reflux pipe 18. Subsequently, this material returns to the tank 1 along the reflux pipe 18, quietly waiting for the centrifuge to complete its maintenance work. Once the centrifuge maintenance is completed and all performance indicators are adjusted to normal, the operator closes valve 16, and the entire equipment resumes normal operation, continuing to provide stable and efficient transfer support for the cytosine preparation process in an orderly manner.

[0034] Working principle: During the use of the crude cytosine preparation centrifuge transfer vessel, the motor 4 is first started to drive the stirring blade 8 to rotate, and at the same time, the fixing bar 9 starts to rotate. Then, the plastic scrapers 11 on both sides of the connecting bar 10 start to scrape the inner wall of the tank 1, so that all the material on the inner wall of the tank 1 is scraped off. Then, this material flows out from the discharge pipe 13 and enters the transport pipe 14 to be transported into the centrifuge to start the centrifugation. When the centrifuge has uneven feeding or poor material separation effect, the valve 16 is opened to let this part of the material enter the diversion pipe 15. At the same time, the return pump 17 is started to draw the material into the return pipe 18, and then it returns to the tank 1 to wait for the centrifuge to be repaired. Then, the valve 16 is closed and the equipment operation is restarted, so that the material re-enters the centrifuge for centrifugation.
