[0018] As Figure 1 and Figure 2 shown, a low-pressure reactor proposed by the present utility model includes a reactor body 1, a partition plate 2, and a cleaning unit; a stirring mechanism 101 is arranged inside the reactor body 1, and the stirring mechanism 101 is driven to rotate by a first motor installed at the top end of the reactor body 1; the partition plate 2 is installed at the upper end of the inner wall of the reactor body 1, a channel 201 is opened on the partition plate 2, a sealing plate 202 is adjustably installed on the partition plate 2, the sealing plate 202 is slidably connected to the partition plate 2, and the diameter of the sealing plate 202 is larger than the diameter of the channel 201; the cleaning unit is composed of a spraying mechanism and a driving mechanism, the driving mechanism is arranged at the top end of the reactor body 1, and the spraying mechanism is driven by the driving mechanism to move and adjust along the height direction inside the reactor body 1 to perform a comprehensive flushing of the inside of the reactor body 1.

[0019] Furthermore, a second motor is arranged at the top end of the partition plate 2, the output end of the second motor extends to the bottom end of the partition plate 2 and is in transmission connection with the sealing plate 202, and a heat dissipation port is arranged at the top end of the reactor body 1 to facilitate heat dissipation during the operation of the second motor.

[0020] Furthermore, the driving mechanism includes a threaded rod 3 and a moving frame 301; the threaded rod 3 is driven to rotate by a third motor installed at the top end of the reactor body 1; the moving frame 301 is threadedly connected to the threaded rod 3, and the moving frame 301 is T-shaped; the input end of the spraying mechanism is installed on the moving frame 301.

[0021] Furthermore, the spraying mechanism includes a water inlet pipe 302, a driving component, and a diversion plate 502; the water inlet pipe 302 is installed on the moving frame 301, and the connection valve at the top end of the water inlet pipe 302 is connected to an external water supply mechanism; the bottom end of the water inlet pipe 302 extends into the reactor body 1, and the water inlet pipe 302 is slidably connected to the top end of the reactor body 1; the driving component is arranged at the bottom end inside the water inlet pipe 302; a plurality of diversion plates 502 are arranged, the diversion plates 502 are hingedly connected to the bottom end of the driving component, the plurality of diversion plates 502 are evenly distributed on the driving component, the plurality of diversion plates 502 are driven by the driving component to rotate and adjust along the water inlet pipe 302, and the driving component can drive the diversion plates 502 to adjust the angle relative to the water inlet pipe 302. An annular rail 504 is arranged on the outer peripheral surface of the water inlet pipe 302, and an annular seat 505 is rotatably connected to the annular rail 504. The cross-sectional view of the annular seat 505 is T-shaped to prevent the annular seat 505 from falling off the annular rail 504.

[0022] Further, the driving assembly and the deflector 502 are located between the inside of the kettle body 1 and the top end of the partition plate 2. The channel 201 corresponds to the driving member. When the stirring mechanism 101 stirs the materials inside the kettle body 1, the driving assembly can be received at the top end of the partition plate 2 to avoid interfering with the stirring. When cleaning is required after stirring, the second motor is used to drive the sealing plate 202 to rotate along the bottom end surface of the partition plate 2, so that the sealing plate 202 no longer blocks the channel 201. At this time, the spraying mechanism can be driven by the driving mechanism to pass through the channel 201 to wash the inside of the kettle body 1.

[0023] In this embodiment, the first motor is used to drive the stirring mechanism 101 to rotate, so as to stir the materials inside the kettle body 1. After the reaction is completed, the materials are discharged through the discharge valve at the bottom end of the kettle body 1. Then, the second motor is used to drive the sealing plate 202 to rotate along the bottom end surface of the partition plate 2, so that the sealing plate 202 no longer blocks the channel 201.

The high-pressure water is adjusted by the driving assembly and sprayed outwards from the bottom end of the water inlet pipe 302. As the third motor drives the threaded rod 3 to rotate clockwise and counterclockwise alternately, the water inlet pipe 302 is driven to move up and down reciprocally along the height direction of the kettle body 1, so as to wash the inner wall of the kettle body 1 and the stirring mechanism 101, and the waste water is discharged through the discharge valve at the bottom end of the kettle body 1.

[0024] Embodiment 2

[0025] As Figure 1 and Figure 3 shown, a low-pressure reaction kettle proposed by the present utility model, compared with Embodiment 1, the driving assembly includes a mounting plate 303, an electric push rod 503 and an annular seat 505; the mounting plate 303 is installed on the inner wall of the water inlet pipe 302, a driving rod 4 is rotatably connected to the mounting plate 303, an impeller 401 is installed at the top end of the driving rod 4, the bottom end of the driving rod 4 extends to the outside of the bottom end of the water inlet pipe 302 and a connecting seat 5 is installed, a plurality of groups of adjusting rods 501 are evenly hinged to the connecting seat 5; the deflector 502 is installed on the corresponding adjusting rods 501; one end of the electric push rod 503 is hinged to the adjusting rod 501; the annular seat 505 is rotatably connected to the water inlet pipe 302, and the end of the electric push rod 503 far from the adjusting rod 501 is hinged to the annular seat 505.

[0026] In this embodiment, high-pressure water impacts the impeller 401, causing the impeller 401 to drive the drive rod 4 to rotate along the mounting plate 303. Then, through the connecting seat 5, the adjusting rod 501, and the electric push rod 503, the annular seat 505 is driven to rotate along the annular rail 504. As the deflector 502 rotates, the high-pressure water can be sprayed outwards in a divergent manner, thereby flushing the inner wall of the kettle body 1 and the stirring mechanism 101. At the same time, by extending or retracting the output end of the electric push rod 503, the adjusting rod 501 can be driven to rotate downwards or upwards along the connecting seat 5, thereby adjusting the angle of the deflector 502 relative to the drive rod 4, and thus adjusting the spraying angle of the high-pressure water, making the flushing angle more perfect and improving the flushing efficiency.
