Description

Technical Field

[0001] The present invention relates to the field of molecular sieve production, in particular to a high-temperature activation system for molecular sieve production. Background Art

[0002] Molecular sieve is a synthetic hydrated aluminosilicate (zeolite) with the function of screening molecules. After the molecular sieve loses water through high-temperature activation, many micropores with uniform pore size are formed inside the crystal, which has a strong adsorption capacity. The preparation process of molecular sieve includes: molecular sieve mixing, granulation, screening, drying, roasting, and packaging. In actual production, after the molecular sieve is produced, it needs to be activated at high temperature before it can be put into use.

[0003] The Chinese patent with announcement number CN111397329 B provides a high-temperature activation system for molecular sieve production. By providing a feeding device on one side of the bracket, the molecular sieve to be dried can be transported to the inside of the drying cylinder. An evacuation piece is provided on the inner wall of the drying cylinder. The evacuation piece includes several dispersion plates and a lifting plate arranged in an inclined state. The dispersion plates and the lifting plate can be used to lift the molecular sieve in the drying cylinder. At the same time, the molecular sieve rolls down along the slope of the inner wall of the drying cylinder. Several dispersion plates enclose a dispersion space, which realizes the dispersion and separation of the molecular sieve while pushing the molecular sieve toward the discharge port for spiral conveying, which is convenient for discharge.

[0004] In summary, during the operation of the above-mentioned granular molecular sieve activation system, the molecular sieve stays in the drying cylinder for a short time. When faced with molecular sieves that require a longer drying time, it is difficult to ensure that the entire sieve is dried at high temperature, thereby reducing the overall activation effect. Moreover, after high-temperature activation, the interior of the molecular sieve crystal is in a state of thermal expansion, and the atomic spacing of the pore skeleton increases due to the high temperature. If it is directly discharged and cooled at this time, thermal stress concentration will result, which will easily cause the crystal to crack and break, thereby affecting its subsequent adsorption and catalytic stability. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a high-temperature activation system for molecular sieve production to solve the technical problem that when facing molecular sieves that require a long drying time, it is difficult to ensure that the entire sieve is fully dried at high temperature, and directly discharging it for cooling will lead to thermal stress concentration, which is easy to cause crystal cracking and breakage, thereby affecting its subsequent adsorption and catalytic stability.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a high-temperature activation system for molecular sieve production, comprising a base, a drying mechanism disposed on the top of the base, a feeding mechanism disposed on one side of the base, a preheating mechanism disposed on the base between the drying mechanism and the feeding mechanism, and a cooling mechanism disposed on the other side of the drying mechanism, a drying cylinder disposed on one side of the feeding mechanism, the drying cylinder extending through one side of the cooling mechanism, the drying cylinder being disposed on one side of the feeding mechanism and being rotatable; A rotating rod is provided for rotation inside the drying cylinder, wherein an adjusting assembly cooperating with the rotating rod is provided inside the drying cylinder, and the adjusting assembly is used to drive the drying cylinder to rotate in opposite directions to the rotating rod, and a pull rod is provided for axial sliding in the rotating rod, and a paddle is elastically hinged on the outer wall of the pull rod, wherein one end of the paddle passes through the rotating rod.

[0007] By adopting the above technical solution, its preheating mechanism facilitates the slow heating of the molecular sieve to avoid thermal stress damage, assists in the step-by-step desorption of impurities, and cooperates with the inert atmosphere to reduce side reactions. The cooling mechanism allows the molecular sieve to be slowly cooled after high-temperature drying, allowing the molecular sieve crystals to gradually shrink from the inside to the outside, and the thermal stress is evenly released. Under normal conditions, the paddle and the rotating rod are arranged radially and perpendicularly, so that the axial components of force on the molecular sieve offset each other, effectively reducing the sliding of the molecular sieve to one side of the drying cylinder. During the sliding of the pull rod to one side, the paddle is located on the outer wall of the rotating rod and is inclined. The inclined paddle will generate an axial component of force on the molecular sieve, and will also push the particles to slide axially to one side through the inclined surface of the paddle.

The cooling gas flows in a circular manner in the spiral flow channel to adsorb the heat source in the drying cylinder, and the exhaust port facilitates the discharge of the gas discharged into the preheating mechanism to the outside, so that the preheating gas always flows in the preheating mechanism. At the same time, the burner on the top of the drying mechanism will accelerate the increase in temperature in the drying mechanism, further improving the drying effect of the granular molecular sieve.

[0013] Preferably, the stepper motor is started to drive the transmission mechanism at the output end to rotate, thereby causing the driving gear to rotate, and the driving gear is engaged with the driven gear on one side to drive the drying cylinder to rotate, so that the drying cylinder rotates during the drying process, further improving the drying effect of the granular molecular sieve.

[0014] The present invention is further configured such that an inner toothed ring is provided on the inner wall of one end of the drying cylinder, and a set of fixed wheels are meshed in the inner toothed ring, an adjusting wheel is rotatably provided in the middle of the fixed wheel, and one end of the adjusting wheel is connected to the rotating rod.

[0015] Preferably, during the rotation of the drying cylinder, the inner gear ring will cause the fixed wheel meshing with it on the inner side to rotate, and the fixed wheel will cause the adjusting wheel at the center position to reverse, thereby achieving that during the rotation of the drying cylinder, the adjusting wheel will drive the rotating rod to rotate in the opposite direction, thereby increasing the disturbance area inside the drying cylinder.

[0016] The present invention is further configured such that one end of the pull rod passes through an adjusting wheel, a driving cylinder is provided on one side of the cooling mechanism, the output end of the driving cylinder is connected to a baffle, the baffle and the pull rod are rotatably arranged, and the baffle is used to drive the pull rod to slide to one side.

[0017] Preferably, the driving cylinder will drive the baffle to squeeze the pull rod, causing the pull rod to slide to one side, and the rotation setting between the baffle and the pull rod facilitates the rotation of the adjusting wheel. One end of the pull rod will rotate stably on one side of the baffle, reducing the friction between the two.

[0018] The present invention is further configured such that the overall width of the adjusting wheel is greater than that of the fixing wheel, and one end of the fixing wheel is connected to a fixing frame, and the fixing frame is connected to the outer wall of the cooling mechanism.

[0019] Preferably, since the overall width of the adjusting wheel is greater than that of the fixed wheel, the transmission stability between the adjusting wheel and the fixed wheel is ensured during the rotation adjustment process, and the stability of the fixed wheel in the drying cylinder is ensured by the fixing frame, thereby achieving stable rotation between the drying cylinder and the rotating rod.

[0020] The present invention is further configured such that a blanking ring is sleeved on one end of the drying cylinder, the blanking ring is connected to the fixing frame, an array of through holes is opened on the drying cylinder at the blanking ring, and a blanking port is opened at the bottom of the blanking ring to cooperate with the through holes.

[0021] Preferably, the discharge ring itself is fixed, so that during the rotation of the drying cylinder, the cooled molecular sieve itself will be discharged from the through hole on the drying cylinder, and under the action of its own gravity, the molecular sieve will be discharged uniformly through the discharge port, making it convenient for the staff to collect it uniformly.

[0022] The present invention is further configured such that the feeding mechanism includes a frame and a feeding bin, wherein the feeding bin is located on the inner wall of the frame, and the feeding bin itself is configured in an oblique cone shape.

[0023] Preferably, the oblique conical feeding bin prevents the granular molecular sieve from being piled up and adhering during the discharge process, and discharges the granular molecular sieve into the drying drum in a unified manner.

When the granular molecular sieve is subsequently transported, the electrically controlled valve is in an open state, and the molecular sieve is slid to one side by the paddle.

[0026] In summary, the present invention mainly has the following beneficial effects: The present invention provides a preheating mechanism between the feeding mechanism and the drying mechanism. The preheating mechanism facilitates preheating of the molecular sieve before it enters the drying mechanism. Its function is to slowly heat up the molecular sieve to avoid thermal stress damage, assist in step-by-step desorption of impurities, and cooperate with an inert atmosphere to reduce side reactions, ultimately ensuring that the molecular sieve structure is intact and the pores are thoroughly activated. In addition, a cooling mechanism is provided on the other side of the drying mechanism. The cooling mechanism allows the molecular sieve to slowly cool down after high-temperature drying, allowing the molecular sieve crystals to gradually shrink from the inside to the outside, uniformly releasing thermal stress, and avoiding particle agglomeration or metal ion migration caused by drastic temperature differences. The present invention provides a rotating rod for the rotation of the drying cylinder. During the drying process, the drying cylinder rotates forward, while the rotating rod rotates reversely under the action of gear meshing, thereby increasing the disturbance area in the drying cylinder and further improving the drying and dehydration effect of the molecular sieve. In this state, the paddle and the rotating rod are arranged radially and perpendicularly, so that the axial forces acting on the molecular sieve offset each other, effectively reducing the molecular sieve from sliding toward one side of the drying cylinder. At the same time, an array of electrically controlled valves is also provided in the drying cylinder, which prevents the molecular sieve from shifting relative to each other between the cooling mechanism, the preheating mechanism, and the drying mechanism during the drying process. The present invention provides a driving cylinder on one side of the cooling mechanism. After the molecular sieve in the drying cylinder is dried, the driving cylinder drives the baffle to slide to one side, so that the pull rod drives the paddle to move. Since the paddle and the pull rod are hinged and connected to the pull rod by a torsion spring, the paddle is located on the outer wall of the rotating rod and is inclined during the sliding of the pull rod. When the drying cylinder rotates, the inclined paddle generates an axial component force on the molecular sieve and pushes the granular molecular sieve to slide axially to one side through the inclined surface of the paddle, thereby transporting the molecular sieve to one side and facilitating the subsequent discharge of the molecular sieve. The present invention provides a fan assembly in the base, and a spiral flow channel is provided around the outer wall of the drying barrel in the cooling mechanism. Cooling gas is drawn in through the air inlet and surrounds the outer wall of the drying barrel, thereby gradually cooling the molecular sieve to be cooled inside. The preheated gas is discharged into the preheating mechanism under the action of the fan assembly. In this process, efficient heat recovery can be achieved and overall energy consumption can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0030] The following describes an embodiment of the present invention based on its overall structure.

[0031] Example 1: Please refer to Figures 1-14 A high-temperature activation system for molecular sieve production is shown, comprising a base 1, a feeding mechanism 2, a preheating mechanism 3, a drying mechanism 4, a cooling mechanism 5, a conveying mechanism and an adjusting mechanism, wherein the feeding mechanism 2 comprises a frame and a feeding bin, wherein the feeding bin is located on the inner wall of the frame, and the feeding bin itself is arranged in an oblique cone shape. The staff introduces the granular molecular sieve into the feeding bin to prevent accumulation and adhesion during the discharge process, and discharges them uniformly into the drying cylinder 7. Under the action of the preheating mechanism 3, the molecular sieve in the drying cylinder 7 can be preheated, so that the molecular sieve is slowly heated to avoid thermal stress damage, assists in step-by-step desorption of impurities, cooperates with an inert atmosphere to reduce side reactions, and is discharged into the drying mechanism 4 on one side after preheating. At the same time, the feeding mechanism 2 continues to convey the granular molecular sieve into the preheating mechanism 3; The drying cylinder 7 is located on one side of the feeding mechanism 2 and is rotatable, and a rotating rod 25 is rotatably arranged in the drying cylinder 7, wherein an adjusting component cooperating with the rotating rod 25 is provided in the drying cylinder 7, and the adjusting component is used to drive the drying cylinder 7 to rotate in the opposite direction of the rotating rod 25, and at the same time, a paddle 17 is provided on the outer wall of the rotating rod 25. In the drying state, the paddle 17 is radially and perpendicularly arranged to the rotating rod 25. The reverse rotation of the drying cylinder 7 and the paddle 17 increases the disturbance area in the drying cylinder 7, further improving the drying and dehydration effect of the molecular sieve, and the paddle 17 is radially and perpendicularly arranged to the rotating rod 25, so that the axial component of force on the molecular sieve offsets each other, effectively reducing the sliding of the molecular sieve to one side of the drying cylinder 7, realizing that the molecular sieve can be dried for a long time in the drying mechanism 4, and improving the overall high-temperature activation effect of different types of molecular sieves; When the drying cylinder 7 is rotated, the inclined paddle 17 will generate an axial component force on the molecular sieve, and will also push the granular molecular sieve to slide axially to one side through the inclined surface of the paddle 17, thereby transporting the molecular sieve to one side and facilitating the subsequent discharge of the molecular sieve into the cooling mechanism 5. At the same time, a sealing ring is provided at the connection between the rotating rod 25 and the paddle 17, and the sealing ring is made of flexible material, which is convenient for the paddle 17 to adjust the angle of the outer wall of the rotating rod 25, which effectively prevents the molecular sieve from entering the interior of the rotating rod 25 during the rotation of the rotating rod 25, thereby further improving the stability of the overall adjustment. An array of electrically controlled valves is provided in the drying cylinder 7, wherein a controller cooperating with the electrically controlled valves is provided on the base 1. The electrically controlled valves are respectively located at the inlet and outlet of the feeding mechanism 2, the preheating mechanism 3, the drying mechanism 4 and the cooling mechanism 5. During the drying, preheating and cooling processes, the electrically controlled valves are in a closed state to prevent the molecular sieve from shifting between the cooling mechanism 5, the preheating mechanism 3 and the drying mechanism 4, thereby improving the overall processing effect. When the granular molecular sieve is subsequently transported, the electrically controlled valves are in an open state, and the molecular sieve is slid to one side for transport through the paddle 17. The cooling mechanism 5 allows the molecular sieve to be slowly cooled after high-temperature drying, allowing the molecular sieve crystals to gradually shrink from the inside to the outside, and the thermal stress to be evenly released, thereby avoiding particle agglomeration or metal ion migration caused by drastic temperature differences. A discharge ring 18 is sleeved on one end of the drying cylinder 7, and the discharge ring 18 is connected to the fixed frame 9. An array of through holes is provided on the drying cylinder 7 at the discharge ring 18, and a discharge port 19 is provided at the bottom of the discharge ring 18 to cooperate with the through holes. The discharge ring 18 itself is fixed, so during the rotation of the drying cylinder 7, the cooled molecular sieve itself will be discharged from the through holes on the drying cylinder 7, and under the action of its own gravity, the molecular sieve will be uniformly discharged through the discharge port 19, making it convenient for the staff to collect it uniformly.

[0032] In the above embodiment, please refer to Figure 4 and Figure 5 A stepping motor 10 is provided on the base 1, and a transmission mechanism 12 is connected to the output end of the stepping motor 10. The transmission mechanism 12 is connected to the driving gear 11, and a driven gear 8 is meshed on one side of the driving gear 11, and the driven gear 8 is sleeved on the outer wall of the drying cylinder 7. By starting the stepping motor 10, the transmission mechanism 12 at the output end is driven to rotate, thereby rotating the driving gear 11. Through the meshing of the driving gear 11 and the driven gear 8 on one side, the drying cylinder 7 is driven to rotate, and the drying cylinder 7 is rotated during the drying process, thereby further improving the drying effect of the granular molecular sieve.

[0033] In the above embodiment, please refer to Figure 7 An inner gear ring 14 is provided on the inner wall of one end of the drying cylinder 7, and a set of fixed wheels 16 are meshed in the inner gear ring 14. An adjusting wheel 15 is rotatably provided in the middle of the fixed wheel 16. One end of the adjusting wheel 15 is connected to the rotating rod 25. During the rotation of the drying cylinder 7, the inner gear ring 14 will cause the fixed wheel 16 meshed with it on the inner side to rotate. Under the action of the fixed wheel 16, the adjusting wheel 15 at the center position is reversed. In this way, during the rotation of the drying cylinder 7, the adjusting wheel 15 will drive the rotating rod 25 to rotate in the opposite direction, so as to increase the disturbance area in the drying cylinder.

[0034] In the above embodiment, please refer to Figure 8One end of the pull rod 13 passes through the adjusting wheel 15, and a driving cylinder 6 is provided on one side of the cooling mechanism 5. The output end of the driving cylinder 6 is connected to a baffle 24, and a rotation setting is provided between the baffle 24 and the pull rod 13, and the baffle 24 is used to drive the pull rod 13 to slide to one side. Under the action of the driving cylinder 6, the baffle 24 will be driven to squeeze the pull rod 13, so that the pull rod 13 slides to one side, and the rotation setting between the baffle 24 and the pull rod 13 facilitates the rotation of the adjusting wheel 15. One end of the pull rod 13 will rotate stably on one side of the baffle 24, reducing the friction between the two.

[0035] Example 2: Please refer to Figure 2 、 Figure 12 and Figure 13 A high-temperature activation system for molecular sieve production is shown, and its overall structure is similar to that of Example 1, wherein the outer wall of the drying cylinder 7 is located in the cooling mechanism 5 and is surrounded by a spiral flow channel 23, and a fan assembly 21 is provided at the bottom of the base 1, and an exhaust pipe 20 is provided at one end of the fan assembly 21, and an exhaust pipe 22 is provided at the other end. One end of the exhaust pipe 20 is connected to the spiral flow channel 23, and one end of the exhaust pipe 22 is connected to the preheating mechanism 3. The cooling gas is drawn in through the air inlet 501 and surrounds the outer wall of the drying cylinder 7, so as to gradually cool down the molecular sieve to be cooled inside, and the preheated gas will be discharged into the preheating mechanism 3 under the action of the fan assembly 21. In this process, efficient heat recovery can be achieved and overall energy consumption can be reduced.

[0036] In the above embodiment, please refer to Figure 2 An exhaust port 301 and an air inlet 501 are respectively provided on one side of the preheating mechanism 3 and the cooling mechanism 5. One end of the air inlet 501 is connected to the spiral flow channel 23. An array of burners 401 is provided on the top of the drying mechanism 4, which is connected to the external air pipe through the air inlet 501, so that the cooling gas is discharged into the spiral flow channel 23. The cooling gas flows around in the spiral flow channel 23 to adsorb the heat source in the drying cylinder 7, and the exhaust port 301 facilitates the discharge of the gas discharged into the preheating mechanism 3 to the outside, so that the preheating gas always flows in the preheating mechanism 3. At the same time, the burner 401 on the top of the drying mechanism 4 will accelerate the increase in temperature in the drying mechanism 4, further improving the drying effect of the granular molecular sieve.

[0037] The present invention is specifically working as follows: when in use, the molecular sieve to be activated at high temperature is discharged into the drying cylinder 7 through the feeding mechanism 2, and then the molecular sieve in the drying cylinder 7 is preheated under the action of the preheating mechanism 3, so that the molecular sieve is slowly heated to avoid thermal stress damage, assists in step-by-step desorption of impurities, and cooperates with the inert atmosphere to reduce side reactions, and then discharged into the drying mechanism 4 on one side. The drying cylinder 7 itself can be rotated by the cooperation of the stepping motor 10 and the transmission mechanism 12. Since a rotating rod 25 is provided for reverse rotation in the drying cylinder 7, the outer wall of the rotating rod 25 is adjustable and provided with a paddle 17. In the drying state, the paddle 17 is radially and perpendicularly arranged to the rotating rod 25. In the process of forward and reverse rotation of the rotating rod 25 and the drying cylinder 7, the disturbance area in the drying cylinder is increased, thereby further improving the drying and dehydration effect of the molecular sieve. After the drying is completed, the baffle 24 at the output end is driven to slide to one side by the driving cylinder 6, so that the pull rod 13 is displaced to one side. Since the paddle 17 and the pull rod 13 are hinged, the paddle 17 is located on the outer wall of the rotating rod 25 and is tilted during the sliding of the pull rod 13 to one side. When the drying cylinder 7 rotates, the inclined paddle 17 will produce an axial component of force on the molecular sieve, and will also push the granular molecular sieve to slide axially to one side through the inclined surface of the paddle 17, so that the dried molecular sieve is discharged into the cooling mechanism 5 on one side. At the same time, the paddle 17 and the pull rod 13 are connected by a torsion spring. When the pull rod 13 is reset by the driving cylinder 6, the paddle 17 is reset under the action of the torsion spring and is radially perpendicular to the rotating rod 25. The cooling mechanism 5 slowly cools down the molecular sieve after high-temperature drying, allowing the molecular sieve crystals to gradually shrink from the inside to the outside, and the thermal stress is evenly released to avoid particle agglomeration or metal ion migration caused by drastic temperature difference.

[0038] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
