Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel cleaning technology, and specifically relates to a reaction vessel heating and cleaning system. Background Technology

[0002] Pharmaceutical intermediates are actually chemical raw materials or products used in the process of drug synthesis. These chemical products do not require a drug production license and can be produced in ordinary chemical plants. As long as they meet certain standards, they can be used in drug synthesis.

[0003] Chinese utility model patent CN221733350U discloses a low-temperature reaction vessel for the production of pharmaceutical intermediates, including a reaction vessel body and a lid. The lid is located on top of the reaction vessel body, and a stirring device is installed inside the reaction vessel body. The stirring device includes a motor, which passes through the top of the lid, and the output shaft of the motor is fixedly connected to a rotating shaft. This utility model uses the driving force of the motor to drive the rotating shaft, sleeve, connecting rod, stirring block one, spring telescopic rod, and stirring block two, etc., to cooperate with each other. This achieves the rotation of the rotating shaft fixed to the output shaft of the motor, thereby causing the sleeve fixed to the circumference of the rotating shaft to rotate. When the sleeve rotates, the connecting rod fixed to the circumference of the sleeve rotates, thereby causing the stirring block one fixed to one end of the connecting rod to rotate. During use, this avoids the material adhering to the inner wall of the reaction vessel body, which would prevent incomplete mixing.

[0004] In order to clean the inside of the reactor, the reactor is equipped with a cleaning device consisting of a water tank, a pressing block, a pressing rod, a baffle plate, a blocking block, a spring telescopic rod, a water pipe, and a nozzle. However, the reactor does not have the function of heating the cleaning solution in the water tank. If the cleaning solution is at a low temperature, the decomposition force of the cleaning solution will be affected, thus affecting the cleaning effect. Utility Model Content

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.

[0024] Please see Figures 1 to 3 As shown, this utility model embodiment provides a reactor heating and cleaning system, including a reactor body 1, a water tank 2 on one side of the reactor body 1, a first conveying pipe 201 fixedly installed on one side of the water tank 2, a motor 3 on the top of the water tank 2, a rotating rod 301 fixedly connected to the output shaft of the motor 3, one end of the rotating rod 301 penetrating through the top of the water tank 2 and extending into the interior of the water tank 2. Stirring blades 302 are fixedly installed on both sides of the rotating rod 301, heating plates 4 are fixedly installed on both sides of the inner wall of the water tank 2, an inlet 7 is fixedly installed on one side of the top of the water tank 2, a temperature sensor 5 is fixedly installed on one side of the water tank 2, one end of the temperature sensor 5 penetrating through one side of the water tank 2 and extending into the interior of the water tank 2. An installation box 6 is fixedly installed on one side of the top of the water tank 2, a PLC controller 601 is installed inside the installation box 6, an inspection door 8 is connected to the front hinge of the installation box 6, a fixing plate 801 is fixedly installed on the outside of the inspection door 8, and a side plate 9 is fixedly installed on the outside of the installation box 6.

[0025] In this embodiment, by setting up a heating plate 4, a temperature sensor 5, and a PLC controller 601, the heating plate 4 can heat the cleaning solution in the water tank 2, and the temperature sensor 5 can monitor the temperature of the cleaning solution in the water tank 2. When the temperature reaches a preset value (in this embodiment, the preset temperature of the cleaning solution is 65±0.5℃), the PLC controller 601 will control the heating plate 4 to stop heating the cleaning solution. The heated cleaning solution can better decompose and remove residues on the inner wall of the reactor, thereby enhancing the cleaning effect. By setting up a motor 3, a rotating rod 301, and a stirring blade 302, the motor 3 can drive the rotating rod 301 and the stirring blade 302 to rotate. The rotating stirring blade 302 can agitate the cleaning solution, keeping it in motion and ensuring that the cleaning solution is heated evenly. By setting up an installation box 6 and an inspection door 8, the installation box 6 and the inspection door 8 can protect the PLC controller 601, making it less susceptible to damage from external contaminants and thus extending its service life.

[0026] Please see Figures 1 to 3 As shown, a water pump 202 is fixedly installed at one end of the first delivery pipe 201, and a second delivery pipe 203 is fixedly installed at the top of the water pump 202. One end of the second delivery pipe 203 passes through the top of the reactor body 1 and extends into the interior of the reactor body 1. A nozzle 204 is fixedly installed at one end of the second delivery pipe 203. By installing the water pump 202, the water pump 202 can deliver the cleaning solution in the water tank 2 to the interior of the reactor body 1, thereby cleaning the interior of the reactor body 1.

[0027] Please refer to Figure 3 As shown, a sealing cap 701 is threadedly connected to the top of the injection port 7. The inner wall of the sealing cap 701 has an internal thread, and the outer wall of the injection port 7 has an external thread. By setting the injection port 7, water and cleaning agent can be injected into the water tank 2. Then, the stirring blade 302 in the water tank 2 is used to stir the water and cleaning agent, so that the water and cleaning agent are mixed into a cleaning solution.

[0028] Please refer to Figure 1 and Figure 4As shown, the side plate 9 has a threaded hole inside, and a bolt 901 is threaded onto the inner wall of the threaded hole. One end of the bolt 901 is located in a locking groove on one side of the fixing plate 801. By setting the bolt 901, the bolt 901 can be moved laterally by turning it. When one end of the bolt 901 moves out of the locking groove on the fixing plate 801, the lock on the inspection door 8 can be released, and the inspection door 8 can be opened, thus facilitating the operation or maintenance of the PLC controller 601 inside the mounting box 6. The bolt 901 is engaged with the fixing plate 801. By setting the bolt 901, the bolt 901 can be moved laterally by turning it. When one end of the bolt 901 is inserted into the locking groove on the fixing plate 801, the inspection door 8 can be locked. An observation window 205 is fixedly provided on the front of the water tank 2, which allows for easy viewing of the remaining amount of cleaning fluid in the water tank 2.

[0029] In use, the heating plate 4 is activated to heat the cleaning solution in the water tank 2. The temperature sensor 5 monitors the temperature of the cleaning solution in the water tank 2. When the temperature reaches the preset value, the PLC controller 601 controls the heating plate 4 to stop heating the cleaning solution. Then, the motor 3 is activated, which drives the rotating rod 301 and the stirring blade 302 to rotate. The rotating stirring blade 302 agitates the cleaning solution, keeping it in motion and ensuring that the cleaning solution is heated evenly. When cleaning the reactor body 1, the water pump 202 is activated, which delivers the cleaning solution from the water tank 2 to the interior of the reactor body 1, thereby cleaning the interior of the reactor body 1.

[0030] When operating or maintaining the PLC controller 601, the bolt 901 is moved laterally by turning it. When one end of the bolt 901 moves out of the locking groove on the fixing plate 801, the lock on the maintenance door 8 can be released, and then the maintenance door 8 can be opened.
