Description

Technical Field

[0001] This utility model relates to the technical field of chemical raw materials, and in particular to a drying device for a nickel-supported catalyst used in BDO production. Background Technology

[0002] As an important raw material for organic and fine chemicals, BDO is widely used in the production of polybutylene terephthalate (PBAT) engineering plastics, tetrahydrofuran (a basic raw material for high-elasticity spandex fibers), γ-butyrolactone (a high-value-added product) and its derivatives, polyurethane artificial leather, elastomers and shoe sole adhesives, etc. It is also a raw material for the synthesis of biodegradable plastic PBAT and has broad market prospects.

[0003] Chinese utility model patent CN212902515U discloses a device that includes a base, with support rods bolted to the top left and right sides of the base, a top seat bolted to the top of the support rods, a hydraulic telescopic rod bolted to the center of the bottom of the top seat, a connecting plate bolted to the bottom of the hydraulic telescopic rod, connecting rods on both the left and right sides of the bottom of the connecting plate, a round rod with a bearing on the inner side of the connecting rod, and a housing on the inner side of the round rod. While this device effectively facilitates the user's heating and drying of the catalyst, and allows for more uniform heating of single-particle catalysts during drying, improving the drying effect of solid catalysts and better meeting practical needs, the water vapor generated during the drying process is difficult to expel and tends to condense and drip from the top of the drying chamber. This phenomenon of condensed water dripping back into the catalyst not only reduces the drying effect but may also adversely affect the catalyst's performance. Furthermore, the catalyst particles are limited by the penetration ability of hot air when heated in a water bath, making it difficult for the hot air to fully act on each catalyst particle. This results in some catalysts being under-dried, while others may be damaged due to over-drying, further affecting the drying effect and performance stability of the catalyst.

[0004] Therefore, in order to address the shortcomings of the above-mentioned problems, a drying device for nickel-supported catalysts in BDO production is proposed. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a drying device for nickel-supported catalysts used in BDO production.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a drying device for nickel-supported catalysts for BDO production, comprising: a drying kettle and a cover plate, a shaking mechanism disposed in the drying kettle, and a draining assembly disposed between the cover plate and the drying kettle;

[0007] The shaking mechanism includes: a shaking frame, a plurality of guide balls disposed on the outer circumference of the shaking frame, a motor disposed at the bottom of the drying kettle, a sleeve disposed on the inner wall of the bottom of the shaking frame, a rotating rod disposed at one end of the output shaft of the motor, and a guide unit disposed on the outer circumference of the rotating rod.

[0008] The inner circumference of the shaking frame has two wavy grooves, and a number of guide balls are fixedly connected to the outer circumference of the shaking frame. The guide balls are respectively located in the two wavy grooves and are slidably connected.

[0009] In a preferred embodiment of this utility model, the motor is fixedly connected to the bottom of the drying kettle, and a rotating rod is fixedly connected to one end of the motor output shaft.

[0010] In a preferred embodiment of this utility model, the rotating rod passes through the drying kettle and is rotatably connected, and a sleeve is fixedly connected to the bottom inner wall of the shaking frame.

[0011] In a preferred embodiment of this invention, the outer circumferential wall of the rotating rod is slidably connected to the inner circumferential wall of the sleeve.

[0012] In a preferred embodiment of this utility model, the guiding unit consists of several guiding blocks, which are fixedly connected to the outer circumferential wall of the rotating rod. The inner circumferential wall of the sleeve is provided with several guiding grooves, and the several guiding blocks are respectively located in the several guiding grooves and slidably connected.

[0013] In a preferred embodiment of this utility model, a protective shell is fixedly connected to the bottom of the drying kettle, and the motor is located inside the protective shell.

[0014] In a preferred embodiment of the present invention, the outer circumferential wall of the protective shell is provided with a plurality of through-hole heat dissipation grooves.

[0015] In a preferred embodiment of this utility model, the draining component includes: a draining surface, the draining surface being disposed on the bottom inner wall of a cover plate, the draining surface being conical, and a draining pipe being connected to the outer circumferential wall of the drying kettle.

[0017] In a preferred embodiment of this invention, a support rod is fixedly connected to the bottom of the drying kettle.

[0018] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0019] (1) This utility model provides a drying device for nickel-supported catalysts used in BDO production. Through the installation of a shaking mechanism, the catalyst is uniformly shaken during the drying process. Driven by a motor, the shaking frame not only rotates in a circular motion but also moves up and down during rotation via the sliding of guide balls within a wave-shaped groove and the sliding connection between the rotating rod and the sleeve. This composite motion mode allows the catalyst to come into more comprehensive contact with the hot air, ensuring the uniformity and efficiency of the drying effect.

[0020] (2) This utility model provides a drying device for nickel-supported catalysts used in BDO production. By incorporating a conical drainage surface, drainage trough, and drainage pipe in the drainage assembly, the problem of liquid residue generated during catalyst drying is effectively solved. The conical drainage surface, with its unique shape, guides the liquid to flow outwards and concentrates it for discharge, subsequently draining it smoothly out of the drying vessel through the drainage trough. This not only prevents liquid accumulation in the drying vessel, ensuring a clean drying environment and stable drying effect, but also greatly improves the drying quality.

[0021] (3) This utility model provides a drying device for nickel-supported catalysts used in BDO production. The protective shell effectively prevents sparks or splashes that may be generated during motor operation from harming operators and the environment, thus enhancing equipment safety. At the same time, the heat dissipation grooves on the protective shell can effectively dissipate the heat generated by the generator during operation, preventing performance degradation or malfunction caused by motor overheating.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] like Figure 1 As shown, a drying device for a nickel-supported catalyst for BDO production includes: a drying kettle 1 and a cover plate 3, a shaking mechanism 5 disposed inside the drying kettle 1, and a draining assembly 4 disposed between the cover plate 3 and the drying kettle 1.

[0030] like Figures 2-3 As shown, the shaking mechanism 5 includes: a shaking frame 501, a plurality of guide balls 502 disposed on the outer circumference of the shaking frame 501, a motor 504 disposed at the bottom of the drying kettle 1, a sleeve 508 disposed on the inner wall of the bottom of the shaking frame 501, a rotating rod 507 disposed at one end of the output shaft of the motor 504, and a guide unit disposed on the outer circumference of the rotating rod 507.

[0031] Two wavy grooves 503 are provided on the inner circumference of the shaking frame 501. Several guide balls 502 are fixedly connected to the outer circumference of the shaking frame 501. The several guide balls 502 are respectively located in the two wavy grooves 503 and are slidably connected.

[0032] The motor 504 is fixedly connected to the bottom of the drying kettle 1. One end of the output shaft of the motor 504 is fixedly connected to a rotating rod 507. The rotating rod 507 passes through the drying kettle 1 and is rotatably connected. The bottom inner wall of the shaking frame 501 is fixedly connected to a sleeve 508. The outer circumference of the rotating rod 507 is slidably connected to the inner circumference of the sleeve 508.

[0033] It should be noted that the rotating rod 507 is driven to rotate by the motor 504, and the shaking frame 501 is slidably connected to the rotating rod 507 through the sleeve 508 fixed to its bottom inner wall, thus creating dynamic movement within the drying kettle 1. The guide ball 502 on the outer circumference of the shaking frame 501 slides within two wavy grooves 503, ensuring uniform and sufficient contact of the catalyst with the hot air, improving drying efficiency, and reducing mechanical wear by minimizing direct friction, thus extending the equipment's lifespan. Furthermore, this design optimizes the structure, simplifies the cleaning and maintenance process, and ensures the equipment's durability and stability, maintaining high performance during long-term operation.

[0034] like Figures 2-4 As shown, the guide unit consists of several guide blocks 510, which are fixedly connected to the outer circumference of the rotating rod 507. The inner circumference of the sleeve 508 is provided with several guide grooves 509, and the several guide blocks 510 are respectively located in the several guide grooves 509 and are slidably connected.

[0035] A protective shell 505 is fixedly connected to the bottom of the drying kettle 1. The motor 504 is located inside the protective shell 505. Several through heat dissipation grooves 506 are opened on the outer circumference of the protective shell 505.

[0036] It should be noted that several guide blocks 510 in the guide unit are fixed to the outer circumference of the rotating rod 507 and slide in cooperation with the guide groove 509 on the inner wall of the sleeve 508. This not only greatly enhances the stability and guiding accuracy of the shaking frame 501 during movement and ensures uniform drying of the catalyst, but also provides protection for the motor 504 with the protective shell 505 at the bottom of the drying tank 1, effectively resisting external interference. The heat dissipation groove 506 opened on it further optimizes the heat dissipation performance of the motor 504.

[0037] like Figures 2-4 As shown, the drain assembly 4 includes: a drain surface 401, which is located on the bottom inner wall of the cover plate 3. The drain surface 401 is conical. A drain pipe 403 is connected to the outer circumferential wall of the drying kettle 1. A drain groove 402 is opened on the upper surface of the drying kettle 1. The outer periphery of the drain surface 401 is located above the drain groove 402. One end of the drain pipe 403 is connected to the drain groove 402. A support rod 2 is fixedly connected to the bottom of the drying kettle 1.

[0038] It should be noted that the conical drainage surface 401, drainage trough 402, and drainage pipe 403 in the drainage assembly 4 effectively solve the problem of liquid residue generated during catalyst drying. The conical drainage surface 401, with its unique shape, guides the liquid to flow outwards and concentrates it for discharge, subsequently draining smoothly out of the drying vessel 1 through the drainage trough 402. This not only prevents liquid accumulation within the drying vessel 1 but also ensures a clean drying environment and stable drying effect.

[0039] In use, the nickel-loaded catalyst is placed inside the shaking frame 501, and then the cover plate 3 is closed and sealed to ensure the interior of the drying kettle 1 is sealed. The motor 504 is started, and its output shaft begins to rotate. The output shaft of the motor 504 directly drives the rotating rod 507 to rotate. The rotation of the rotating rod 507 causes the sleeve 508 to slide on it. The sleeve 508 is fixedly connected to the bottom inner wall of the shaking frame 501, so the shaking frame 501 moves as the sleeve 508 slides. Simultaneously, the guide ball 502 on the outer circumference of the shaking frame 501 slides within two wavy grooves 503. The shape and arrangement of the wavy grooves 503 cause the guide ball 502 to experience varying forces during sliding, thereby further enhancing the shaking effect of the shaking frame 501. Guided by the rotating rod 507 and the sleeve 508, the shaking frame 501 shakes in both circumferential and vertical directions. This shaking is achieved through the rotation of the rotating rod 507 and the sliding engagement of the sleeve 508. During the drying process, the moisture or other liquids contained in the catalyst are evaporated and flow along the conical drain surface 401 to the drain tank 402. The design of the conical drain surface 401 allows the liquid to flow smoothly into the drain tank 402, preventing liquid accumulation in the drying vessel 1. The drain tank 402 is connected to the drain pipe 403. When the liquid accumulates to a certain level, it is discharged from the drying vessel 1 through the drain pipe 403. After the drying process is completed, the motor 504 is turned off, stopping the shaking of the shaking frame 501. The cover plate 3 is opened to unload the dried catalyst from the shaking frame 501. The equipment is cleaned and maintained to prepare for the next use.

[0040] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
