[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Example 1:

[0028] Based on the existing problem of harm caused by the inability to regulate pressure, please refer to Figures 1-4 This utility model provides a technical solution: a reaction device for producing paclobutrazol, a plant growth regulator with adjustable pressure, including a reaction vessel 1, a feed inlet connected to the top surface of the reaction vessel 1, a controller body 2 provided on the front surface of the reaction vessel 1, a pressure detector body 3 penetrating through the top surface of the reaction vessel 1, a pressure regulating mechanism 4 provided on the right end surface of the reaction vessel 1, and a stirring mechanism 5 provided on the inner side of the reaction vessel 1.

[0029] The pressure regulating mechanism 4 includes a pressure regulating section 41 and a purification section 42;

[0030] Purification section 42 is located on the bottom surface of pressure regulating section 41;

[0031] The stirring mechanism 5 includes a drive unit 51 and a stirring unit 52;

[0032] The stirring part 52 is located on the outer side of the drive part 51.

[0033] The pressure regulating unit 41 includes a support plate 411, which is fixedly connected to the reactor 1. A connecting pipe 412 is provided on the top surface of the support plate 411. A through hole is opened on the right end face of the connecting pipe 412. A sealing ring is provided on the inner side of the through hole. The connecting pipe 412 is connected to the reactor 1. An exhaust pipe 413 is provided on the outer end face of the connecting pipe 412. The exhaust pipe 413 extends through to the bottom of the support plate 411.

[0034] A piston 414 is installed above the exhaust pipe 413. The piston 414 is slidably connected to the connecting pipe 412. A slide rod 415 is installed on the right end face of the piston 414. The slide rod 415 is fixedly connected to the piston 414. The slide rod 415 extends through to the right side of the connecting pipe 412. The slide rod 415 is slidably connected to the through hole. A baffle 416 is installed on the right end face of the slide rod 415. The baffle 416 is fixedly connected to the slide rod 415.

[0035] The purification unit 42 includes a cylinder 421. The output end face of the cylinder 421 is fixedly connected to the right end face of the baffle 416. A fixed seat 422 is provided on the bottom surface of the cylinder 421. The fixed seat 422 is fixedly connected to the cylinder 421. The bottom surface of the fixed seat 422 is fixedly connected to the top surface of the support plate 411. A conveying pipe 423 is provided below the fixed seat 422. The top end of the conveying pipe 423 is connected to the bottom end face of the first exhaust pipe 413. A purification box 424 is connected to the bottom end face of the conveying pipe 423. A sealing door is hinged to the front side of the purification box 424. An exhaust pipe 425 is connected to the right end face of the purification box 424.

[0036] A sliding groove 426 is provided on the left side of the exhaust pipe 425. The sliding groove 426 is located on the inner side of the purification box 424 and is fixedly connected to the purification box 424. A purification plate 427 is provided on the inner side of the sliding groove 426 and is slidably connected to the sliding groove 426.

[0037] Furthermore, in this embodiment, through the pressure regulating mechanism 4 and the cylinder 421 in the purification unit 42, when the pressure inside the reactor 1 is too high, the pressure detector body 3 will promptly detect this abnormality. After detecting the abnormality, the pressure detector body 3 will immediately transmit this signal to the controller body 2. Upon receiving the signal, the controller body 2 will quickly respond and drive the cylinder 421 in the purification unit 42 to operate. After the cylinder 421 is driven, it will drive the baffle 416 and the slide rod 415 to move. The movement of the slide rod 415 further drives... The piston 414 extends and retracts, causing the exhaust pipe 413 to open, thus releasing the compressed gas in the reactor 1. The released compressed gas enters the purification box 424 through the delivery pipe 423. In the purification box 424, the compressed gas is purified by the purification plate 427. The purified gas is finally discharged from the exhaust pipe 425. When the purification plate 427 becomes blocked due to long-term use, the purification box 424 can be opened, and the purification plate 427 can be pulled out by sliding it in the slide groove 426, which facilitates cleaning and maintenance.

[0038] Furthermore, in this embodiment, through the pressure regulating mechanism 4, the cylinder 421 in the purification unit 42 is used. When the pressure detector body 3 detects that the pressure in the reactor 1 is too high, the pressure detector body 3 transmits the signal to the controller body 2. The controller body 2 drives the cylinder 421, which drives the baffle 416 and the slide rod 415. As a result, the slide rod 415 drives the piston 414 to extend and retract, thereby opening the exhaust pipe 1 413. After the exhaust pipe 1 413 is opened, the compressed gas enters the purification box 424 through the conveying pipe 423. After being purified by the purification plate 427, it is discharged from the exhaust pipe 2 425. When the purification plate 427 is blocked, the purification box 424 is opened, and the purification plate 427 is pulled to slide away from the slide groove 426, thereby cleaning. This solves the problem that the gas generated during the mixing and reaction of materials in the reactor 1 causes the pressure inside the reactor 1 to increase, making it impossible to discharge the material immediately, and the problem that the discharged material cannot be purified, which may cause harm to the human body.

[0039] Example 2:

[0040] Please see Figure 1 , Figure 2 , Figure 5 Furthermore, based on Embodiment 1, the following is obtained: the drive unit 51 includes an L-shaped plate 511, which is fixedly connected to the reactor 1. A motor 512 is provided on the inner side of the L-shaped plate 511, which is fixedly connected to the L-shaped plate 511. A rotating rod 513 is provided on the output end face of the motor 512, which is fixedly connected to the motor 512. The rotating rod 513 extends through to the inner side of the reactor 1 and is rotatably connected to the inner wall of the reactor 1 through a bearing seat.

[0041] The stirring unit 52 includes a stirring rod 521, which is fixedly connected to the rotating rod 513. A stirring rod 522 is provided below the stirring rod 521 and is fixedly connected to the rotating rod 513. A scraper 523 is provided on the outer end face of the stirring rod 522 and is fixedly connected to the outer end face of the stirring rod 521.

[0042] Furthermore, in this embodiment, the stirring mechanism 5 utilizes the motor 512 in the drive unit 51. When it is necessary to stir the material in the reactor, the motor 512 is started. After the motor 512 is started, its rotational power is transmitted to the rotating rod 513. After receiving the power, the rotating rod 513 starts to rotate. The rotating rod 513 further drives the stirring rod 1 521 and the stirring rod 2 522 to perform stirring action. At the same time, the rotating rod 513 also drives the scraper 523 to perform scraping action along the inner wall of the reactor. The design of the scraper 523 ensures that it can closely fit the inner wall of the reactor 1 and effectively scrape off the material attached to the wall.

[0043] Furthermore, in this embodiment, the stirring mechanism 5 utilizes the motor 512 in the drive unit 51 to drive the rotating rod 513, which in turn drives the stirring rod 521, the stirring rod 522, and the scraper 523, thereby achieving uniform stirring while scraping the inner wall with the scraper 523, thus avoiding the problems of inconvenient cleaning and uneven stirring.

[0044] In use, the raw materials are fed into the reactor through the inlet. The stirring mechanism 5, driven by the motor 512 in the drive unit 51, activates the motor 512 when stirring is required. The motor 512 transmits its rotational power to the rotating rod 513, which then rotates. This rotation further drives the stirring rods 521 and 522 to perform stirring. Simultaneously, the rotating rod 513 drives the scraper 523 to scrape along the inner wall of the reactor. The scraper 523 is designed to fit tightly against the inner wall of the reactor 1, effectively removing material adhering to the wall. The pressure regulating mechanism 4, using the cylinder 421 in the purification unit 42, detects excessive pressure inside the reactor 1 when the pressure is too high. The pressure detector 3 then detects this abnormality. Afterwards, this signal will be immediately transmitted to the controller body 2. Upon receiving the signal, the controller body 2 will respond quickly and drive the cylinder 421 in the purification unit 42 to operate. After the cylinder 421 is driven, it will drive the baffle 416 and the slide rod 415 to move. The movement of the slide rod 415 will further drive the piston 414 to extend and retract. The extension and retraction of the piston 414 will cause the exhaust pipe 1 413 to be opened, thereby releasing the compressed gas in the reactor 1. The released compressed gas enters the purification box 424 through the delivery pipe 423. In the purification box 424, the compressed gas is purified by the purification plate 427. The purified gas is finally discharged from the exhaust pipe 2 425. When the purification plate 427 is blocked due to long-term use, the purification box 424 can be opened, and the purification plate 427 can be pulled out by sliding in the slide groove 426, thereby facilitating cleaning and maintenance.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
