For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0022] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] The embodiment of the present invention provides a modified catalyst blending device, such as Figures 1 to 10 As shown, the blending device includes a blending kettle 101, on top of which a head 102 is installed and sealed by a plurality of bolts, a mounting frame 107 is coaxially fixed to the top of the head 102, and a driving motor 103 is fixedly installed on the top of the mounting frame 107.

[0024] A solid feed port 104 is fixedly installed on the side of the blending kettle 101, and the solid feed port 104 is used to transport solid materials or catalysts into the blending kettle 101. An exhaust port 105 is fixedly installed on the head 102, and the exhaust port 105 is used to discharge the gas in the reaction process from the blending kettle 101. A discharge ball valve 110 is fixedly installed on the bottom of the blending kettle 101, and the discharge ball valve 110 is used to discharge the modified catalyst after blending.

[0025] A liquid feed port 106 is fixedly installed on the top of the mounting frame 107, and a distribution trough 108 is annularly provided inside the mounting frame 107. The liquid feed port 106 is connected with the distribution trough 108. The bottom of the distribution trough 108 is fixed and connected with the first ends of a plurality of feed pipes 109 along the circumferential direction. A liquid delivery mechanism 300 is fixedly installed on the second end of the feed pipe 109. The liquid delivery mechanism 300 will fully mix the liquid transported to the inside of the blending kettle 101 through the liquid feed port 106, the distribution trough 108 and the feed pipe 109 with the solid material in the blending kettle 101.

[0026] The output end of the driving motor 103 is equipped with a stirring mechanism 200 via a driving shaft. The stirring mechanism 200 is arranged inside the blending kettle 101 to complete solid-liquid mixing and material discharge.

[0027] A driving shaft coaxially fixed with the output end of the driving motor 103 sealably passes through the mounting frame 107 and the top of the head 102, and is coaxially fixedly connected to the mounting box 201. A stirring blade 202 is rotatably mounted on the side of the mounting box 201. An inner cavity 203 is provided inside the stirring blade 202. A limit slider 204 that reciprocates along its length is sealed inside the inner cavity 203. The limit slider 204 is fixedly connected to the telescopic plate 205. The side of the telescopic plate 205 fits tightly with the inner side of the through hole opened at the top of the stirring blade 202 to prevent the material or catalyst in the blending kettle 101 from entering the inner cavity 203.

[0028] The two sides of the limit slider 204 are respectively fixed to the output ends of the two electric cylinders 206. The two electric cylinders 206 are arranged along the length direction of the inner cavity 203, and the two electric cylinders 206 are installed inside the inner cavity 203 to drive the limit slider 204 and the telescopic plate 205 to reciprocate along the length direction of the inner cavity 203.

[0029] The structure consisting of the stirring blades 202 , the inner cavity 203 , the limit slider 204 , the telescopic plate 205 , and the electric cylinder 206 is evenly installed in multiple groups along the circumference of the installation box 201 , preferably 2 groups.

[0030] The drive motor 103 and the electric cylinder 206 are respectively connected to the user terminal signal, so that the user can directly control the drive motor 103 and the electric cylinder 206, thereby facilitating the realization of the above functions.

[0031] Through the above structure, when the driving motor 103 drives the installation box 201 to rotate through the driving shaft, the installation box 201 will synchronously drive the stirring blades 202 to rotate in the same direction. Figure 4 When the structure shown in the figure rotates in the clockwise direction, the stirring blade 202 and the telescopic plate 205 can push the mixture in the blending kettle 101 to a high place along the upper surface of the stirring blade 202, and then slide down along the side and high place of the stirring blade 202 and the telescopic plate 205, so that the materials can be fully contacted during the sliding process, thereby improving the mixing effect; when Figure 4 When the structure shown in the figure rotates counterclockwise, the lower surface of the stirring blade 202 contacts the mixture in the blending kettle 101 and presses downward, thereby facilitating the discharge of the mixture.

[0032] The bottom of the installation box 201 is coaxially fixed with a slurry pusher 111, which is arranged in the slope groove 112 and rotates along it. The slope groove 112 is coaxially opened at the bottom of the blending kettle 101, and the blades of the slurry pusher 111 are arc-shaped structures, which can cooperate with the stirring mechanism 200 to facilitate the mixing or discharge of materials. When the stirring blades 202 revolve around the installation box 201 along the Figure 4 When the stirring blade 202 rotates clockwise in the mounting box 201, the pushing slurry 111 is synchronously driven to rotate in the slope groove 112. At this time, the pushing slurry 111 pushes the material in the blending kettle 101 from the outside of the intermediate phase to facilitate the mixing of the material. Figure 4 When the mixing kettle 101 rotates counterclockwise, the slurry pusher 111 pushes the material in the mixing kettle 101 from the outside to the center, thereby facilitating the discharge of the material.

[0033] For further explanation of the present invention, see Figure 7 , 89. The bottom of the material delivery pipe 109 is fixed and connected to the material distribution ring 301. The bottom of the material distribution ring 301 is sealed and rotatably installed with a sealing ring 302. The sealing ring 302 can completely block the bottom of the material distribution ring 301. The sealing ring 302 is fixed to the first ends of a plurality of first pipes 303. The first pipes 303 are connected to the inside of the material distribution ring 301. The first pipes 303 pass through the top of the installation box 201 and are arranged in the installation box 201. A pump body 304 is installed on the first pipe 303 for pumping the liquid in the material distribution ring 301 downward. The second end of the first pipe 303 is rotatably installed. There is a first end of a rotating tube 305, which is rotatably mounted on the side wall of the mounting box 201. The side and second end of the rotating tube 305 are respectively fixedly mounted and connected with a nozzle 306, and the nozzle 306 faces the upper side and outer side of the stirring blade 202, and is used to spray liquid into the mixture that slides down from the stirring blade 202 and the upper side and outer side of the telescopic plate 205. In this way, the mixture and the liquid can be contacted and mixed in equal proportions, ensuring that the mixture and the liquid in the blending kettle 101 can fully contact in a certain proportion, thereby greatly improving the mixing effect of the solid-liquid mixture.

[0034] The structure consisting of the first pipeline 303 , the pump body 304 , the rotating tube 305 , and the nozzle 306 is evenly distributed and installed around the sealing ring 302 in multiple groups, preferably 2 groups.

[0035] Among them, Figure 3 As shown, the nozzle 306 is located below the stirring blade 202, and a guard plate 307 is installed below the nozzle 306. The guard plate 307 is fixedly connected to the lower surface of the stirring blade 202. The guard plate 307 protects the nozzle 306 and prevents the stirring blade 202 from moving along the stirring blade 202. Figure 4 When rotating counterclockwise as shown, the mixture at the bottom of the blending kettle 101 directly contacts the nozzle 306 , thereby blocking the nozzle hole of the nozzle 306 or causing damage to the nozzle 306 .

[0036] For further explanation of the present invention, see Figure 7 , 8 , 10. An adjusting mechanism 400 is also installed inside the installation box 201 for adjusting the inclination angle of the stirring blade 202 and the nozzle 306. The adjusting mechanism 400 includes a servo motor 401, a screw 402, a driving slider 403, a first pin 404, a second pin 405, a first slot 406, a second slot 407, a guide rail 408 and a rotating shaft 409. The bottom of the installation box 201 is fixed to the servo motor 401, and the output end of the servo motor 401 is coaxially fixed to the screw 402. The screw 402 is threadedly connected to a threaded hole provided on the driving slider 403. The driving slider 403 is arranged in the guide rail 408 and slides back and forth along it. The guide rail 408 is fixed to the inner surface of the installation box 201.

[0037] The bottom of the side surface of the driving slider 403 is fixed to the first pin shaft 404 . The first pin shaft 404 is disposed in the first slot 406 and moves along the first slot 406 . The first slot 406 is fixed to the outer surface of the rotating tube 305 .

[0038] The top of the side of the driving slider 403 is fixed to the second pin shaft 405, the second pin shaft 405 is arranged in the second slot 407 and moves along it, the second slot 407 is fixed to the first end of the rotating shaft 409, the rotating shaft 409 passes through the side wall of the installation box 201 and is rotatably installed on the installation box 201, and the second end of the rotating shaft 409 is fixed to the side of the stirring fan blade 202.

[0039] Through the above structure, when the servo motor 401 drives the screw rod 402 to rotate forward, the driving slider 403 slides upward along the guide rail 408. At this time, through the configuration relationship between the first pin shaft 404 and the second slot 407 and the configuration relationship between the second pin shaft 405 and the second slot 407, the first slot 406 drives the rotating tube 305 to press Fig.10 The second slot 407 drives the shaft 409 to rotate counterclockwise around its axis. Fig.10 The counterclockwise rotation in the mixing kettle 101 drives the stirring blade 202 and the nozzle 306 to rotate synchronously in the same direction, so that the angle between the stirring blade 202 and the bottom of the blending kettle 101 becomes larger. Conversely, when the driving slider 403 slides downward along the guide rail 408, the angle between the stirring blade 202 and the bottom of the blending kettle 101 becomes smaller, thereby enabling the stirring blade 202 to stir and mix the materials in the blending kettle 101 at various angles, and by adjusting the inclination angle, it is more convenient to discharge the materials during reverse rotation.

[0040] According to the embodiments of the present invention as described above, these embodiments do not describe all the details in detail, nor do they limit the invention to specific embodiments. Obviously, many modifications and changes can be made based on the above description. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and the modified use based on the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
