Description

Technical Field

[0001] The invention relates to the technical field of methane preparation devices, and in particular to a preparation device and a preparation method of a methane aromatization catalyst. Background Art

[0002] Methane is the main component of natural gas and plays an important role in the global energy structure. With the continuous increase in natural gas production and the gradual reduction of oil resources, the efficient conversion of methane into high-value-added chemicals is of great strategic significance. Methane aromatization reaction is one of the important ways to convert methane, which can convert methane into aromatic compounds such as benzene, toluene, and naphthalene. These aromatics are the basic raw materials for the synthesis of many chemical products such as plastics, fibers, and rubber;

[0003] Generally, before preparing a catalyst, it is necessary to fully stir a variety of raw materials to allow them to fully react. Generally, existing devices basically use a stirring paddle to stir the raw materials. Since the catalyst raw materials contain more solid particles when stirring, traditional devices are difficult to fully disperse the particles in the raw materials when mixing the particle-containing raw materials through a stirring paddle, and local agglomeration is likely to occur during stirring, resulting in the raw materials being easily over- or under-concentrated locally during stirring, affecting the reaction efficiency of the raw materials.

[0017] S2: When the middle roller rotates, the rotation of the middle roller will drive the vertical plate and the connecting plate to rotate synchronously. When the connecting plate rotates, it will stir the materials inside the main body to make them mixed and react;

[0018] S3: After sufficient stirring, the motor is stopped and the discharge pipe is opened, so that the mixture inside the main body enters the next process.

[0019] The present invention has the following beneficial effects:

[0020] 1. In the present invention, when the middle roller drives the vertical plate and the connecting plate to rotate, the rotation of the connecting plate will drive multiple rotating rods to rotate synchronously. When the middle roller drives the rotating rod to rotate through the vertical plate, the gear shaft at the top of one of the rotating rods will rotate in the annular groove at the bottom of the fixed cylinder and drive the gear shaft to rotate back and forth through the staggered gear plates. When the gear shaft reciprocates, it will drive other rotating rods to rotate back and forth synchronously through two gear shafts. Then, when the middle roller drives the vertical plate and the rotating rod to stir the raw materials inside the main body, the fast-rotating middle roller will make the raw materials inside the main body flow rapidly between the multiple rotating rods and the rectangular grooves opened on the side walls of the rotating rods. Then, the fast-flowing mixed raw materials will pass between the rectangular grooves and the two flexible plates. The raw materials flow rapidly, and when the raw materials pass through the two flexible plates, the flexible plates will shake in a wave-like manner under the flow and resistance of the raw materials. When the two flexible plates shake, the two flexible plates will form a kneading motion on the materials passing through the flexible plates. At this time, the materials can be mixed when they are stirred. At the same time, the kneading of the flexible plates can also gradually disperse the different raw materials, break the possible agglomeration between the materials, and make the materials subject to forces in different directions, thereby greatly increasing the adequacy of material mixing. At the same time, while achieving fully distributed mixing, it can also prevent the raw material concentration from being too high or too low locally inside the main body, thereby enabling the raw materials to be more fully mixed and improving the uniformity of catalyst preparation and reaction efficiency.

[0021] 2. In the present invention, when the rotation of the middle roller drives the connecting plate to quickly stir the raw materials inside the main body, the raw materials inside the main body will quickly pass through the two fixed cylinders and flow quickly. When the raw materials are flowing quickly, the flow of the raw materials will impact the fan sleeve. When the fan sleeve is impacted by the raw materials, the fan sleeve will rotate under the flow of the raw materials and slide on the fixed rod. When the fan sleeve rotates, the rotation of the fan sleeve will drive the limit ring to rotate through the telescopic sleeve. When the limit ring rotates, the rotation of the limit ring will drive the spherical plate to rotate. After that, when the fan sleeve is impacted by the raw materials and slides forward on the surface of the fixed rod, the sliding of the fan sleeve will drive the sliding cylinder to slide synchronously. When the fan sleeve drives the sliding cylinder to slide, the sliding of the sliding cylinder will squeeze the elastic shaft so that the elastic shaft expands outward. When the elastic shaft expands outward, the expansion of the elastic shaft will push the arc frame to fit against the side wall of the flexible plate and play a certain supporting role. At the same time, when the fan sleeve is When the surface of the fixed rod slides forward, the sliding of the fan sleeve will push the spherical plate through the middle plate, causing the spherical plate to expand, and push the telescopic ring to expand through the flexible ring and the limit material. When the telescopic ring expands, it will drive the arc frame through the elastic shaft and combine with the expansion of the elastic shaft to make the flexible surface of the arc frame fit against the side wall of the flexible plate. Then, when the fan sleeve rotates, the rotation of the fan sleeve will drive the spherical plate to rotate. When the spherical plate rotates, it will periodically knock on the fixed rod. When the fixed rod is knocked, the vibration force generated will be transmitted to the arc frame, causing the multiple elastic plates 2 inside the arc frame to shake. When the elastic plate 2 shakes, it will knock on the side wall of the flexible plate and transmit the vibration force, so that the raw materials remain dispersed before entering the two flexible plates to prevent blockage caused by agglomeration. At the same time, when the arc frame expands and fits on the surface of the flexible plate, it can provide a support point for the flexible plate, which can reduce the degree of local deformation of the flexible plate when it is subjected to a large material flow impact or stirring force. Reducing the possibility of excessive depression or stretching of the flexible plate can keep it in a relatively stable shape and avoid excessive local deformation, thereby ensuring the regularity and stability of the flexible plate's kneading of the material and helping to maintain a stable stirring effect.

[0022] 3. In the present invention, when the rotation of the middle roller stirs the raw materials, the rotation of the middle roller will drive the limiting ring 2 and multiple cleaning boxes to rotate synchronously. When the limiting ring 2 and the cleaning box are rotating, the rapid flow of the raw materials will impact the spherical chain. After being impacted, the spherical chain will shake up and down. When shaking, the spherical chain will drive the connecting plate to rotate up and down. When the connecting plate rotates, it will slide up and down inside the semicircular frame. At the same time, when the connecting plate rotates up and down, the rotation of the connecting plate will drive the intermediate shaft through the connecting plate 2 so that the intermediate shaft slides back and forth inside the circular frame. When the intermediate shaft slides back and forth, the sliding of the intermediate shaft will drive the diaphragm to shake back and forth inside the circular frame. At the same time, when the cleaning box rotates, the rotation of the cleaning box will wipe the inside of the main body to clean the raw materials attached to the inner wall of the main body. At the same time, when the cleaning box stirs the raw materials, the rapid flow of the raw materials will enter the inside of the cleaning box through the round hole on the cleaning box. At the same time, when the diaphragm shakes in the direction of the intermediate shaft, the diaphragm The spherical valve is pushed open and the raw materials are pushed into the connecting plate by the reciprocating shaking of the diaphragm. Then, the raw materials in the cleaning box can be pressurized into the connecting plate through the shaking of the diaphragm and enter the spherical chain through the connecting plate. At this time, the raw materials in the cleaning box can be quickly sprayed from the liquid outlet on the side wall of the spherical chain to the rectangular groove on the rotating rod under the continuous pressurization of the diaphragm on the raw materials in the cleaning box. Then, when the cleaning box rotates on the inner wall of the main body for cleaning, the solids in the raw materials can be reduced from adhering to the inner wall of the main body and local sedimentation in the main body. Then, when the spherical chain sprays out the raw materials, the extracted mixed liquid can be sprayed to the rectangular groove on the rotating rod, so that the flexible plate can further mix the sprayed raw materials evenly, thereby maintaining the suspended state of the raw materials in the main body, effectively preventing the raw materials from excessively gathering and settling in a certain area inside the main body, thereby improving the reaction efficiency and enhancing the stirring effect.

When the connecting plate 203 rotates, it will stir the materials inside the main body 1 to make them mix and react. After sufficient stirring, stop the motor 105 and open the discharge pipe 101, so that the mixture inside the main body 1 enters the next process.

[0052] When the middle roller 201 drives the vertical plate 202 and the connecting plate 203 to rotate, the rotation of the connecting plate 203 will drive the multiple rotating rods 204 to rotate synchronously. When the middle roller 201 drives the rotating rods 204 to rotate through the vertical plate 202, the gear shaft 303 on the top of one of the rotating rods 204 will rotate in the annular groove at the bottom of the fixed cylinder 104 and drive the gear shaft 303 to reciprocate through the staggered gear plates. When the gear shaft 303 reciprocates, it will drive the other rotating rods 204 to reciprocate synchronously through the two gear shafts 303. Then, when the middle roller 201 drives the vertical plate 202 and the rotating rod 204 to stir the raw materials inside the main body 1, the rapidly rotating middle roller 201 will make the raw materials inside the main body 1 flow rapidly between the multiple rotating rods 204 and the rectangular grooves opened on the side walls of the rotating rods 204. Then, the rapidly flowing The mixed raw materials will flow rapidly between the rectangular groove and the two flexible plates 301. When the raw materials pass through the two flexible plates 301 again, the flexible plates 301 will shake in a wave-like manner under the flow and resistance of the raw materials. When the two flexible plates 301 shake, the two flexible plates 301 will form a kneading motion on the materials passing through the flexible plates 301. At this time, the materials can be mixed when the raw materials are stirred. At the same time, the kneading of the flexible plates 301 can also gradually disperse different raw materials, break up possible agglomerations between the materials, and make the materials act on in different directions, thereby greatly increasing the adequacy of material mixing. At the same time, while achieving fully distributed mixing, it can also prevent the raw material concentration from being too high or too low locally inside the main body 1, so that the raw materials can be more fully mixed, thereby improving the uniformity of catalyst preparation and reaction efficiency.

[0053] When the rotation of the middle roller 201 drives the connecting plate 203 to quickly stir the raw materials inside the main body 1, the raw materials inside the main body 1 will quickly pass through the two fixed cylinders 104 and flow quickly. When the raw materials are flowing quickly, the flow of the raw materials will impact the fan sleeve 403. When the fan sleeve 403 is impacted by the raw materials, the fan sleeve 403 will rotate under the flow of the raw materials and slide on the fixed rod 402. When the fan sleeve 403 is rotating, the rotation of the fan sleeve 403 will drive the limiting ring 405 to rotate through the telescopic cylinder 404. When the limiting ring 405 rotates The rotation of the limiting ring 405 will drive the spherical plate 406 to rotate. After that, when the fan sleeve 403 is impacted by the raw material and slides forward on the surface of the fixed rod 402, the sliding of the fan sleeve 403 will drive the sliding cylinder 501 to slide synchronously. When the fan sleeve 403 drives the sliding cylinder 501 to slide, the sliding of the sliding cylinder 501 will squeeze the elastic shaft 502 so that the elastic shaft 502 expands outward. When the elastic shaft 502 expands outward, the expansion of the elastic shaft 502 will push the arc frame 505 to fit the side wall of the flexible plate 301 and play a certain supporting role. At the same time, when the fan sleeve 403 is fixed When the surface of the rod 402 slides forward, the sliding of the fan sleeve 403 pushes the spherical plate 406 through the middle plate 407, so that the spherical plate 406 expands, and pushes the telescopic ring 503 to expand through the flexible ring and the limit material. When the telescopic ring 503 expands, it drives the arc frame 505 through the elastic shaft 502. Combined with the expansion of the elastic shaft 502, the flexible surface of the arc frame 505 fits the side wall of the flexible plate 301. Then, when the fan sleeve 403 rotates, the rotation of the fan sleeve 403 drives the spherical plate 406 to rotate, and the spherical plate 406 periodically knocks the fixed rod 402 when rotating. When the fixed rod 402 is struck, the vibration force generated will be transmitted to the arc frame 505, causing the multiple elastic plates 506 inside the arc frame 505 to shake. When the elastic plates 506 shake, they will knock the side wall of the flexible plate 301 and transmit the vibration force, so that the raw materials remain dispersed before entering the two flexible plates 301, preventing blockage caused by agglomeration. At the same time, when the arc frame 505 expands and fits on the surface of the flexible plate 301, it can provide a support point for the flexible plate 301, which can reduce the local deformation of the flexible plate 301 when it is subjected to a large material flow impact or stirring force. Reduce the possibility of excessive depression or stretching of the flexible plate 301, so that it can maintain a relatively stable shape and avoid excessive local deformation, thereby ensuring the regularity and stability of the flexible plate 301 kneading the material, which helps to maintain a stable stirring effect.

[0054] When the intermediate roller 201 rotates to stir the raw materials, the rotation of the intermediate roller 201 will drive the limiting ring 2 602 and the multiple cleaning boxes 601 to rotate synchronously. When the limiting ring 2 602 and the cleaning boxes 601 are rotating, the rapid flow of the raw materials will impact the ball chain 706. After being impacted, the ball chain 706 will shake up and down. When shaking, the ball chain 706 will drive the connecting plate 705 to rotate up and down. When the connecting plate 705 rotates, it will slide up and down inside the semicircular frame 701. At the same time, when the connecting plate 705 rotates up and down, the rotation of the connecting plate 705 will pass through the connecting plate 2 704 The intermediate shaft 703 is driven to slide back and forth inside the circular frame 603. When the intermediate shaft 703 slides back and forth, the sliding of the intermediate shaft 703 drives the diaphragm 702 to swing back and forth inside the circular frame 603. At the same time, when the cleaning box 601 rotates, the rotation of the cleaning box 601 wipes the inside of the main body 1 to clean the raw materials attached to the inner wall of the main body 1. At the same time, when the cleaning box 601 stirs the raw materials, the rapid flow of the raw materials will enter the inside of the cleaning box 601 through the circular hole on the cleaning box 601. At the same time, the square of the intermediate shaft 703 on the diaphragm 702 When the diaphragm 702 is shaken in the direction of the circular hole, the diaphragm 702 will also absorb the external raw materials into the cleaning box 601. At the same time, when the diaphragm 702 shakes in the direction of the circular hole, it will squeeze the raw materials inside the cleaning box 601, so that the raw materials will push open the ball valve 604 and enter the interior of the connecting plate 705. After that, under the reciprocating shaking of the diaphragm 702, the raw materials inside the cleaning box 601 can be pressurized into the interior of the connecting plate 705 through the connecting plate 705 and enter the ball chain 706 through the connecting plate 705. At this time, under the continuous pressure of the diaphragm 702 on the raw materials inside the cleaning box 601, the raw materials can be quickly discharged from the outlet on the side wall of the ball chain 706. The liquid hole sprays toward the rectangular groove on the rotating rod 204, and then when the cleaning box 601 rotates and cleans the inner wall of the main body 1, the solids in the raw materials can be reduced from adhering to the inner wall of the main body 1 and locally settling in the main body 1. Then, when the spherical chain 706 sprays the raw material, the extracted mixed liquid can be sprayed toward the rectangular groove on the rotating rod 204, so that the flexible plate 301 can further evenly mix the sprayed raw materials, thereby maintaining the suspended state of the raw materials in the main body 1, and effectively preventing the raw materials from excessively gathering and settling in a certain area inside the main body 1, thereby improving the reaction efficiency and enhancing the stirring effect.
