Description

Technical Field

[0001] This utility model relates to the field of catalyst production technology, specifically a drying device for catalyst production. Background Technology

[0002] Catalysts often contain moisture or solvents during their preparation, which need to be removed through drying to ensure their activity, stability, and subsequent performance. Catalysts are widely used in chemical, energy, and environmental protection fields and play an important role. By reducing the activation energy required for a reaction, catalysts enable reactions that are originally slow or difficult to occur to proceed efficiently. This ability makes catalysts one of the core components of modern industry.

[0003] However, when existing drying devices dry catalysts, the hot air inside the device usually rises automatically, causing excessive high temperature to accumulate in the upper part of the device. This prevents the hot air from increasing its contact time with the catalyst. At the same time, the moisture on the outer surface of the agglomerated catalyst evaporates, but the moisture inside does not evaporate easily, resulting in poor catalyst drying effect. Utility Model Content

[0004] This invention provides a drying device for catalyst production, which solves the problem mentioned in the background art that the hot air inside the drying device generally rises automatically, causing excessive high temperature to accumulate in the upper part of the device, which prevents the hot air from increasing the contact time with the catalyst. At the same time, the moisture on the outer surface of the agglomerated catalyst evaporates, but the internal moisture does not evaporate easily, resulting in poor catalyst drying effect.

[0005] This utility model provides the following technical solution: a drying device for catalyst production, including a drying cylinder and a vent at the top, a discharge pipe is provided below the drying cylinder, a threaded discharge cover is movably provided on the discharge pipe, a driving mechanism is provided above the drying cylinder, a drying component is provided on the driving mechanism, a stirring component is provided on the drying component, a partition is fixed inside the drying cylinder, a connecting shaft is fixed on the partition, and a feed cover is hinged to the drying cylinder.

[0006] Preferably, the drive mechanism includes a motor base fixed on the drying cylinder, a dual-shaft motor fixed on the motor base, a first rotating shaft fixed to the output shaft of the dual-shaft motor via a coupling, a gear fixed on the first rotating shaft, a rotating disk movably mounted on the gear, the rotating disk having tooth grooves that mesh with the gear, a second rotating shaft fixed to the output shaft of the dual-shaft motor via a coupling, a fan blade fixed on the second rotating shaft, a protective net provided at the fan blade, and the protective net being fixedly connected to the drying cylinder, with anti-collision pads fixed on the protective net.

[0007] Preferably, the drying assembly includes a heat-conducting cylinder fixed to the rotating disk, and a heating tube and a hot water coil are fixed on the heat-conducting cylinder respectively. The hot water coil includes a water inlet end and a water outlet end, and threaded sealing plugs are movably provided on both the water inlet end and the water outlet end.

[0008] Preferably, the stirring component includes a stirring plate fixed to the outer ring of the heat-conducting cylinder, a crossbar fixed below the stirring plate, a limit spring and a movable block respectively movable on the crossbar, and a movable plate fixed on the movable block.

[0009] Preferably, the drying cylinder has a pre-reserved through groove to accommodate the movement of the heat-conducting cylinder, the outer ring of the heat-conducting cylinder is provided with an annular limiting part, and a bearing is provided on the side of the heat-conducting cylinder away from the annular limiting part, and the inner ring of the bearing is fixedly connected to the connecting shaft.

[0010] Preferably, both the inner ring of the water inlet end and the inner ring of the water outlet end are provided with threaded grooves that are adapted to the threaded sealing plug, and both the water inlet end and the water outlet end are threadedly connected to the threaded sealing plug.

[0011] Preferably, a concave groove is reserved below the mixing plate to accommodate the movement of the movable plate, and a crossbar and a limiting spring are fixed in the concave groove.

[0012] This utility model has the following beneficial effects:

[0013] 1. The rotating shaft at one end is driven by a dual-shaft motor, which in turn drives the fan blades to rotate. When the hot air inside the drying cylinder rises, the rotating fan blades blow the rising hot air downwards, preventing excessive high temperature from accumulating in the upper part of the device. This keeps the hot air at the bottom of the drying cylinder, increasing the contact time between the catalyst and the hot air, and ensuring that both the surface and interior of the catalyst are thoroughly dried.

[0014] 2. By using a dual-shaft motor to drive the other end of the shaft to rotate, the gear can be driven to rotate and mesh with the tooth groove. At the same time, the rotating disk rotates and the heat-conducting cylinder rotates synchronously. This allows the stirring plate to stir the catalyst while the heat-conducting cylinder is rotating, increasing the heating surface and further increasing the contact time between the catalyst and the hot air. At the same time, it can prevent the desiccant from accumulating and clumping.

[0015] 3. The drying method can be switched through the drying component. When the heating tube cannot be used normally, hot water is injected through the water inlet to fill the hot water coil. The heat energy generated by the hot water heats the heat conduction cylinder, thereby increasing the temperature inside the drying cylinder. This allows the heating method to be switched when the heating tube cannot work normally, without affecting the normal production of the catalyst. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 As shown, a drying device for catalyst production includes a drying cylinder 1 and a vent 2 at the top. A discharge pipe 3 is provided below the drying cylinder 1, and a threaded discharge cover 4 is movably mounted on the discharge pipe 3. A drive mechanism 5 is provided above the drying cylinder 1, and a drying component 6 is provided on the drive mechanism 5. A stirring component 7 is provided on the drying component 6. A partition 8 is fixed inside the drying cylinder 1, and a connecting shaft 9 is fixed on the partition 8. A feed cover 10 is hinged to the drying cylinder 1.

[0025] Please see Figures 1-6As shown, in this embodiment: the drive mechanism 5 includes a motor base 51 fixed on the drying cylinder 1, a dual-shaft motor 52 fixed on the motor base 51, and a rotating shaft 53 fixed to the output shaft of the dual-shaft motor 52 via a coupling. When one end of the dual-shaft motor 52 is turned on, the rotating shaft 53 rotates to synchronize the gear 54. The gear 54 meshes with the tooth grooves 56 on the rotating disk 55, causing the rotating disk 55 to be driven to rotate, thereby allowing the heat-conducting cylinder 61 to rotate inside the drying cylinder 1. A gear 54 is fixed on the rotating shaft 53, and a rotating disk 55 is movably mounted on the gear 54. The rotating disk 55 is provided with tooth grooves 56 that mesh with the gear 54. A second rotating shaft 57 is fixed to the output shaft of the dual-shaft motor 52 via a coupling. A fan blade 58 is fixed on the second rotating shaft 57. When the other end of the dual-shaft motor 52 is turned on, the second rotating shaft 57 rotates, causing the fan blade 58 to rotate and blow the rising hot air downwards, preventing excessive high temperature from accumulating in the upper part of the device and keeping the hot air at the bottom of the drying cylinder 1. A protective net 59 is provided at the fan blade 58, and the protective net 59 is fixedly connected to the drying cylinder 1. An anti-collision pad 510 is fixed on the protective net 59. When the stirring plate 71 rotates, it will come into contact with the protective net 59. The protective net 59 can protect the fan blade 58 and prevent the fan blade 58 from colliding and being damaged by the stirring plate 71. The protective net 59 is provided with an anti-collision pad 510 to avoid collisions that could cause the protective net 59 to be dented.

[0026] Please see Figures 2-4 As shown, in this embodiment: the drying assembly 6 includes a heat-conducting cylinder 61 fixed to the rotating disk 55. A heating tube 62 and a hot water coil 63 are fixed on the heat-conducting cylinder 61. When the heating tube 62 cannot be used normally, hot water can be sent into the hot water coil 63 through the inlet end 64. The heat energy generated by the hot water can increase the temperature inside the heat-conducting cylinder 61, thereby increasing the temperature inside the drying cylinder 1. This ensures that the normal production of the catalyst is not affected when the heating tube 62 cannot be used. The hot water coil 63 includes an inlet end 64 and an outlet end 65. Threaded sealing plugs 66 are movable on both the inlet end 64 and the outlet end 65. When the hot water coil 63 is not in use or is filled with water, it can be sealed to prevent water from leaking out. At the same time, it is convenient to replace the hot water in the hot water coil 63 at regular intervals.

[0027] Please see Figures 2-5As shown, in this embodiment: the stirring component 7 includes a stirring plate 71 fixed to the outer ring of the heat-conducting cylinder 61. When the heat-conducting cylinder 61 rotates, the stirring plate 71 rotates synchronously, which can stir the catalyst accumulated at the bottom of the drying cylinder 1, so that it can fully contact the hot air and avoid accumulation leading to agglomeration. A crossbar 72 is fixed below the stirring plate 71. A limit spring 73 and a movable block 74 are respectively movable on the crossbar 72. When the stirring plate 71 contacts the protective net 59, the movable plate 75 is subjected to force and rotates under the cooperation of the movable block 74 and the crossbar 72. The limit spring 73 is also subjected to force and deforms. When the stirring plate 71 rotates away from the protective net 59, the movable plate 75 is reset back into the stirring plate 71 by the rebound force of the limit spring 73. The movable plate 75 is fixed on the movable block 74 to avoid restricting the rotation of the stirring plate 71 with the protective net 59.

[0028] Please see Figures 1-6 As shown, in this embodiment: the drying cylinder 1 has a pre-reserved through groove to accommodate the movement of the heat-conducting cylinder 61. The outer ring of the heat-conducting cylinder 61 is provided with an annular limiting part. By connecting the heat-conducting cylinder 61 and the drying cylinder 1 in a sleeve installation manner, the cooperation of the annular limiting part prevents the structure from separating, and allows the heat-conducting cylinder 61 to rotate stably inside the drying cylinder 1. A bearing is provided on the side of the heat-conducting cylinder 61 away from the annular limiting part, and the inner ring of the bearing is fixedly connected to the connecting shaft 9. When the heat-conducting cylinder 61 rotates, it is connected to the connecting shaft 9 through the bearing, so that the heat-conducting cylinder 61 can be movably installed with the partition plate 8, and the heat-conducting cylinder 61 remains stable when rotating.

[0029] Please see Figures 1-2 As shown in this embodiment: the inner ring of the water inlet end 64 and the inner ring of the water outlet end 65 are both provided with threaded grooves that are compatible with the threaded sealing plug 66, and the water inlet end 64 and the water outlet end 65 are both threadedly connected to the threaded sealing plug 66. When the hot water coil 63 is not in use or when it is filled with water, it can be sealed to prevent water from leaking out, and at the same time, it is convenient to replace the hot water in the hot water coil 63 at regular intervals.

[0030] Please see Figures 2-5 As shown in this embodiment: a concave groove is reserved below the stirring plate 71 to accommodate the movement of the movable plate 75. The crossbar 72 and the limiting spring 73 can be installed in the concave groove, so that the movable plate 75 has a movable space. The crossbar 72 and the limiting spring 73 are fixed in the concave groove, so that the movable plate 75 can move under the cooperation of the crossbar 72 and the limiting spring 73 and has a reset function.
