DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Example 1

[0025] like Figure 1-Figure 4 As shown, the utility model provides a reactor with a self-cleaning function, comprising a reactor barrel 1 and a water spray assembly 2. A gas inlet 11 is installed on one side of the side wall of the reactor barrel 1, a liquid inlet 12 is installed on the side wall of the reactor barrel 1 and above the gas inlet 11, and an explosion-proof motor 13 is installed on the top of the reactor barrel 1 through a motor seat. The explosion-proof motor 13 is electrically connected through an external terminal, and the output end of the explosion-proof motor 13 is transmission-connected to a stirring cavity rod 14, which is rotatably connected inside the reactor barrel 1, and three groups of stirrers 15 are installed below the stirring cavity rod 14. The water spray assembly 2 is arranged on the stirring cavity rod 14, and is used to spray water on the surface of the stirring cavity rod 14 and the stirrer 15. The water spray assembly 2 includes a moving ring 21 slidably connected to the top of the stirring cavity rod 14, and a limiting groove 22 is provided at the front and rear ends of the middle part of the stirring cavity rod 14. An electric push rod 23 is installed inside the limiting groove 22. The electric push rod 23 is electrically connected through an external terminal, and the moving end of the electric push rod 23 is fixedly connected to the moving ring 21. A first connecting plate 24 in a ring array is installed on the outside of the moving ring 21, and a water spray ring 25 is installed on the side of the first connecting plate 24 away from the moving ring 21. A water tank connected to an external water pipe is provided inside the water spray ring 25, and a water pump is installed inside the water tank. Three groups of water spray connecting rods 26 are arranged below the water spray ring 25, and a rotator is provided on the top of the water spray connecting rod 26, and the rotator is connected to the water tank. Three groups of first nozzles 27 are installed on the front and rear ends of the outer side of the water spray connecting rod 26, and the first nozzle 27 is a square structure.

[0026] When it is necessary to clean the scale inside the reactor barrel 1, the movable ring 21 is driven to move downward by starting the electric push rod 23. At the same time, the stirring cavity rod 14 can be driven to rotate by the explosion-proof motor 13. The water pump inside the water tank is turned on, so that the water inside the water spray ring 25 enters through the water spray connecting rod 26, and then the water is sprayed through the first nozzle 27. The first nozzle 27 on the water spray connecting rod 26 can simultaneously spray the stirring cavity rod 14 and the outer surface of the agitator 15, and can also spray the inner wall of the reactor barrel 1. This design can ensure that the scale cleaning water flow covers a wider area, increase the cleaning area, and improve the overall spraying efficiency of the present invention.

[0027] like Figure 3 and Figure 4As shown, a driving assembly 210 for driving the water spraying connecting rod 26 to rotate is provided on the stirring cavity rod 14, and the driving assembly 210 includes a driving ring 211 that is rotatably connected to the top of the moving ring 21, and a driving limit rod 212 is installed on the outside of the stirring cavity rod 14, and the driving limit rod 212 is in a spiral structure on the outside of the stirring cavity rod 14. A notch that matches the driving limit rod 212 is provided on the inside of the driving ring 211, and a second connecting plate 213 in an annular array is installed on the outside of the driving ring 211, and a first gear 214 is installed on the side of the second connecting plate 213 away from the driving ring 211. The top of the water spraying connecting rod 26 slides through the water spraying ring 25 and is installed with a second gear 215, and the first gear 214 and the second gear 215 are meshed.

[0028] When the moving ring 21 moves downward, the notch inside the driving ring 211 is matched with the driving limit rod 212, so that the driving ring 211 rotates on the moving ring 21. This rotational movement is transmitted to the first gear 214 through the second connecting plate 213, thereby driving the first gear 214 to rotate. Then, the meshing action between the first gear 214 and the second gear 215 will cause the water spray connecting rod 26 to rotate accordingly. The rotational movement of the water spray connecting rod 26 will cause the first nozzle 27 to rotate inside the reactor barrel 1, thereby expanding the spraying area. This design can improve the cleaning effect by increasing the spraying area, because the rotational movement of the water spray connecting rod 26 makes the water spray cover a wider range, and can more comprehensively clean the surface of the stirring cavity rod 14 and the reactor barrel 1.

[0029] like Figure 3 As shown, a second nozzle 271 is installed at the bottom of the first connecting plate 24, the first connecting plate 24 is connected to the water tank inside the water spray ring 25, the outlet end of the second nozzle 271 is at a corresponding position along the surface of the stirring cavity rod 14, the second nozzle 271 is connected to the water tank, and the second nozzle 271 is a pointed structure.

[0030] The function of the second nozzle 271 is to provide additional spray force during the cleaning process. By aiming the outlet end of the nozzle at the surface of the mixing cavity rod, the water spray can directly impact the dirt or sediment on the mixing cavity rod to enhance the cleaning effect. This can ensure that the surface of the mixing cavity rod is thoroughly cleaned and improve the cleaning quality and efficiency of the equipment.

[0031] like Figure 3 and Figure 5 As shown, the diameter of the outlet end of the first nozzle 27 is larger than the diameter of the agitator 15 .

[0032] Since the diameter of the outlet end of the first nozzle 27 is larger than the diameter of the agitator 15, this means that during the cleaning process, the water flow sprayed by the first nozzle 27 can cover the area around the agitator 15 more widely, thereby further improving the cleaning effect. Example 2

[0033] like Figure 3 , Figure 5 and Figure 6 As shown, the top of the internal outlet end of the first nozzle 27 located at the bottom is rotatably connected to an adjusting baffle 221, the outer side of the first nozzle 27 is rotatably connected to a telescopic block 222 fixedly connected to the adjusting baffle 221, a fixed seat 223 is installed on the outer side of the first nozzle 27, the telescopic block 222 is rotatably connected to the side close to the water spray connecting rod 26 with a moving block 224, a spring rod 225 that slides through the inside of the fixed seat 223 is installed below the moving block 224, and a pressure block seat 226 is installed below the spring rod 225.

[0034] When the water spray connecting rod 26 moves downward, the pressure block seat 226 will contact the bottom wall of the reactor tube 1, and the contact force will be transmitted to the spring rod 225. At this time, the spring inside the spring rod 225 enters a compressed state, so that the moving block 224 drives the telescopic block 222 to rotate, and the telescopic block 222 will extend. The telescopic block 222 can drive the adjusting baffle 221 inside the first nozzle 27 to rotate a certain angle, so that the adjusting baffle 221 changes the injection angle of the outlet end of the first nozzle 27, so that the first nozzle 27 can spray along the bottom wall of the reactor tube 1 when discharging water, which is convenient for cleaning the scaling of the reactor tube 1.

[0035] The working principle is as follows: when the reactor with self-cleaning function is used, when it is necessary to clean the scale inside the reactor barrel 1, the moving ring 21 is driven to move downward by starting the electric push rod 23, and the stirring cavity rod 14 can also be driven to rotate by the explosion-proof motor 13, and the water pump inside the water tank is turned on, so that the water inside the water spray ring 25 enters through the water spray connecting rod 26, and then the water is sprayed through the first nozzle 27. The first nozzle 27 on the water spray connecting rod 26 can simultaneously spray the stirring cavity rod 14 and the outer surface of the agitator 15, and can also spray the inner wall of the reactor barrel 1. When the moving ring 21 moves downward, the notch inside the driving ring 211 is adapted to the driving limit rod 212, so that the driving ring 211 rotates on the moving ring 21. This rotational movement is transmitted to the first gear 214 through the second connecting plate 213, thereby driving the first gear 214 to rotate, and then, the meshing action between the first gear 214 and the second gear 215 will cause the water spray connecting rod 26 to rotate. The rotational movement of the water spray connecting rod 26 will cause the first nozzle 27 to rotate inside the reactor tube 1. When the water spray connecting rod 26 moves downward, the pressure block seat 226 will contact the bottom wall of the reactor tube 1, and the contact force will be transmitted to the spring rod 225. At this time, the spring inside the spring rod 225 enters a compressed state, so that the moving block 224 drives the telescopic block 222 to rotate, and the telescopic block 222 will extend. The telescopic block 222 can drive the adjusting baffle 221 inside the first nozzle 27 to rotate a certain angle, so that the adjusting baffle 221 changes the injection angle of the outlet end of the first nozzle 27, so that the first nozzle 27 can spray along the bottom wall of the reactor tube 1 when discharging water.
