Description

Technical Field

[0001] This invention belongs to the field of catalyst support drying technology, and particularly relates to a spherical catalyst support drying device. Background Technology

[0002] Currently, the industry commonly uses mesh belt furnace drying systems for drying spherical catalyst supports. The core working logic is as follows: the spherical catalyst support to be dried is laid on the surface of the mesh belt, and the support is smoothly fed into the pre-set drying area inside the furnace through the continuous conveying function of the mesh belt; hot air at a constant temperature is generated and transported inside the furnace through a hot air circulation system. The hot air makes full contact with the support on the mesh belt, and the moisture in the support evaporates through heat conduction and convection, completing the drying process. To avoid problems such as poor hot air penetration and uneven drying caused by excessively thick support layers on the mesh belt, existing technologies typically add a vibrating feeder and a uniform material plate to the mesh belt conveyor path: the vibrating feeder uses high-frequency vibration to initially disperse the support, while the uniform material plate pushes the accumulated support to the sides or flattens it through relative movement with the mesh belt surface, ensuring that the support forms a uniformly thick layer on the mesh belt.

[0003] Although existing mesh belt furnace drying systems have addressed the issue of uneven carrier thickness to some extent through the combination of vibrating feeders and uniform distribution plates, significant shortcomings remain in practical applications, leading to a series of negative consequences. Firstly, because the particle size of the spherical catalyst carrier is often similar to the mesh size of the mesh belt, some carrier material easily becomes embedded in the mesh openings during conveying and vibration dispersion, causing clogging. Secondly, in the early and middle stages of drying, a large amount of free water remains on the carrier surface. The clogged mesh directly hinders the water vapor formed after the free water evaporates from the bottom of the mesh belt, prolonging the residence time of free water on the carrier surface and significantly reducing the overall drying rate, making it difficult to meet the demands of high-efficiency production. Secondly, during the process of the material leveling plate being pushed, the carrier embedded in the mesh will make hard contact with the bottom of the material leveling plate. On the one hand, this hard contact is prone to causing damage and cracking of the carrier surface, reducing the yield. On the other hand, the force generated by the contact will further squeeze the carrier into the depth of the mesh, aggravating the degree of mesh blockage, resulting in the need for frequent shutdowns for cleaning and maintenance of the conveyor belt, shortening the actual service life of the conveyor belt, and increasing equipment maintenance costs and the risk of production interruption.

[0004] Therefore, there is an urgent need for a spherical catalyst support drying device that can avoid the problems of catalyst support easily getting embedded in the mesh belt holes, making it difficult for free water to drain from the mesh belt and the catalyst support being easily damaged. Summary of the Invention

[0005] To address the aforementioned problems, the present invention provides a spherical catalyst support drying device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: The present invention provides a spherical catalyst carrier drying device, including a shell, a conveyor frame fixedly arranged inside the shell, a mesh belt arranged within the conveyor frame, and the outer surface of the mesh belt divided into multiple material spreading areas by multiple transverse isolation strips and two longitudinal isolation strips. Multiple air supply components are arranged on both the upper and lower sides of the material-carrying section of the mesh belt, and lifting mechanisms are arranged on both the left and right sides of the mesh belt. Two connecting beams capable of sliding along the height direction of the conveyor frame are arranged on the lifting mechanisms. The upper air supply components are arranged between the upper left and right connecting beams, and multiple sets of variable-pitch guide components are arranged between the lower left and right connecting beams and the conveyor frame. The lower air supply components are respectively connected to the corresponding variable-pitch guide components. A sealing component connected to the upper two connecting beams is arranged above the mesh belt, and the sealing component is used to periodically seal the ports of the material spreading areas. By cooperating with the lifting mechanism and the variable pitch guide assembly, multiple air supply components below are controlled to move upward and closer to the material-carrying section of the mesh belt. At the same time, multiple adjacent air supply components can be driven to move closer to each other, increasing the upward air supply intensity of the lower air supply components to the material-carrying section of the mesh belt. With the cooperation of the sealing component, the spherical catalyst carrier on the mesh belt is driven to tumble and change position.

[0007] According to an advantageous embodiment, the conveyor frame is provided with a drive assembly for driving the mesh belt to move.

[0008] According to an advantageous embodiment, two longitudinal isolation strips are fixedly disposed on the left and right edges of the mesh belt and extend along its length, respectively, and multiple transverse isolation strips are fixedly disposed on the surface of the mesh belt and evenly distributed along its length.

[0009] According to an advantageous embodiment, the air supply assembly includes a mounting base, on which multiple air supply nozzles are fixedly mounted, and the multiple air supply nozzles on the same mounting base are connected together by an air supply pipe. Connecting shafts are fixedly connected to both the left and right sides of the mounting base. The upper mounting base is fixedly connected to the upper left and right connecting beams respectively through the connecting shafts on the left and right sides, and the lower mounting base is connected to the corresponding pitch guide assembly through the connecting shaft.

[0010] According to an advantageous embodiment, the lifting mechanism includes two double-ended screws rotatably mounted on the conveying frame and distributed front to back. The same end of the upper and lower connecting beams on the same side is threadedly connected to the corresponding double-ended screws in opposite directions. A motor is fixedly mounted on the conveying frame near the upper end of the double-ended screws, and the output shaft of the motor is fixedly connected to the upper end of the corresponding double-ended screw.

[0011] According to an advantageous embodiment, the variable pitch guide assembly includes a sliding sleeve that is slidably sleeved on the lower connecting beam. The sliding sleeve is fixedly connected to the connecting shaft in the corresponding lower air supply assembly. Multiple sets of guide plate assemblies are fixedly arranged on both the left and right sides of the conveying frame. Each set of guide plate assemblies consists of multiple guide plates with different inclination angles. The guide plates are provided with strip-shaped guide holes, and the connecting shaft in the lower air supply assembly is movably disposed in the corresponding strip-shaped guide hole.

[0012] According to an advantageous embodiment, an I-shaped guide wheel is coaxially rotatably mounted on the surface of the connecting shaft, and the I-shaped guide wheel is rotatably disposed within a strip-shaped guide hole.

[0013] According to an advantageous embodiment, the enclosure component includes an outer frame that is fixedly connected to the corresponding upper connecting beam via a connecting plate. Multiple enclosure baffles are rotatably disposed inside the outer frame via a rotating shaft. Drive components two for driving the enclosure baffles to rotate are disposed on both the front and rear sides of the outer frame.

[0014] According to an advantageous embodiment, the second drive assembly includes a transmission gear fixedly connected to one end of a rotating shaft. A slide rail is provided on the upper side of the outer frame near the transmission gear. A drive gear plate that can slide left and right is slidably connected on the slide rail. The drive gear plate meshes with the corresponding transmission gear. An electric push rod is fixedly provided on the outer frame near the drive gear plate. The telescopic end of the electric push rod is fixedly connected to the corresponding drive gear plate.

[0015] Compared with the prior art, the spherical catalyst carrier drying device provided in this embodiment of the invention has the following beneficial effects: First, by driving the lower air supply component to move upward through the lifting mechanism and bringing it closer with the help of the variable pitch guide component, the local air supply intensity is increased without increasing the air source pressure. This can blow the carrier that is stuck at the mesh belt hole port upward to avoid mesh blockage, and can also accelerate the evaporation of free water on the carrier surface and the discharge of water vapor. At the same time, combined with strong wind rolling and breaking up the locally accumulated carrier, the material layer is always uniform, ensuring that the hot air can fully penetrate and greatly improving the drying rate.

[0016] Secondly, it abandons the traditional mechanical extrusion method of material distribution plates, and uses strong wind to drive the carrier to roll in a small range within the material distribution area. There is also a closed component above to prevent the carrier from colliding hard with the external structure, which effectively reduces carrier damage and improves the yield.

[0017] Thirdly, since there is no need for the material leveling plate to rub against the mesh belt, and the mesh clogging can be reduced from the source, it not only reduces the need for frequent cleaning and maintenance of the mesh belt, reducing equipment maintenance costs and the risk of production interruption, but also extends the service life of the mesh belt.

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will now be described in further detail.

[0026] Please refer to the following: Figure 1 and Figure 2 A spherical catalyst carrier drying device includes a shell 1, a conveyor frame 2 fixedly disposed inside the shell 1, a mesh belt 3 disposed within the conveyor frame 2, and a drive assembly (not shown in the figure) for moving the mesh belt 3 mounted on the conveyor frame 2. The drive assembly in this design includes four conveyor rollers rotatably mounted on the conveyor frame 2 and arranged in a rectangular pattern. The mesh belt 3 is fitted onto the four conveyor rollers, and one of the conveyor rollers is driven by an external drive motor. The drive motor drives the conveyor rollers to rotate, thereby moving the mesh belt 3.

[0027] See Figure 2 , Figure 4 and Figure 5To prevent the spherical catalyst carrier material from rolling and detaching from the mesh belt 3 after being laid, the outer surface of the mesh belt 3 is divided into multiple spreading zones 6 by multiple transverse isolation strips 4 and two longitudinal isolation strips 5. The two longitudinal isolation strips 5 are fixedly installed on the left and right edges of the mesh belt 3 and extend along its length, while the multiple transverse isolation strips 4 are fixedly installed on the surface of the mesh belt 3 and evenly distributed along its length. During the movement of the mesh belt 3, a certain amount of material is poured into each spreading zone 6 on the mesh belt 3 by an external quantitative feeding mechanism, ensuring that the material poured into the spreading zone 6 does not overflow and can cover the outermost layer of the mesh belt 3. The quantitative feeding mechanism in this scheme can be an electromagnetic vibrating feeder. Utilizing the principle of electromagnetic vibration, the feeding trough vibrates, and the granular material moves forward along the feeding trough under the action of vibration. By controlling the amplitude and frequency of the electromagnetic vibration, quantitative feeding is achieved.

[0028] See Figures 2-5 Multiple air supply components 7 are provided on both the upper and lower sides of the material-carrying section of the mesh belt 3. Lifting mechanisms 8 are provided on both the left and right sides of the mesh belt 3. Two connecting beams 9 that can slide along the height direction of the conveying frame 2 are provided on the lifting mechanism 8. The multiple air supply components 7 above are all located between the two upper left and right connecting beams 9. Multiple sets of variable pitch guide components 10 are provided between the two lower left and right connecting beams 9 and the conveying frame 2. The multiple lower air supply components 7 are respectively connected to the corresponding variable pitch guide components 10. A closing component 11 connected to the two upper connecting beams 9 is provided on the upper part of the mesh belt 3.

[0029] In actual operation, under normal conditions, the closed component 11 is in an open state, and the multiple air supply components 7 above and below blow air towards the upper and lower sides of the material carrying section of the mesh belt 3 to dry the spherical catalyst carrier on the mesh belt 3.

[0030] The mesh belt 3 slowly conveys material from front to back. After conveying a certain distance, the mesh belt 3 is driven by two lifting mechanisms 8 to bring the upper and lower connecting beams 9 closer to each other. When the two upper connecting beams 9 move downward, they simultaneously drive the closing component 11 to move closer to the upper side of the material-carrying section of the mesh belt 3. At this time, the closing component 11 changes from the original open state to the closed state and finally descends to the upper port of the material-laying area 6 on the mesh belt 3, blocking the upper port of the material-laying area 6. Simultaneously, the two connecting beams 9 below move upward, causing multiple air supply components 7 below to move closer to the lower side of the material-carrying section of the mesh belt 3. As the multiple air supply components 7 below move upward, they gradually converge through the variable pitch guide component 10, causing multiple adjacent air supply components 7 below to move upward and merge into a small area to jointly supply air to the lower side of the material-carrying section of the mesh belt 3. Without adjusting the external air source pressure, the air supply intensity of the air supply components 7 to the lower side of the material-carrying section of the mesh belt 3 is increased, thereby blowing the spherical catalyst carriers in the spreading area 6 from bottom to top, allowing them to roll and adjust their positions. The upper port of the spreading area 6 is blocked by the sealing component 11, allowing them to adjust their positions only within a small range within the spreading area 6. At the same time, it will cause the spherical catalyst carriers that may remain at the hole port of the mesh belt 3 to be blown upward. In the early and middle stages of drying, this helps the spherical catalyst carriers that have been piled up to disperse, and at the same time, it facilitates the discharge of free water on the surface of the spherical catalyst carriers along the holes of the mesh belt 3.

[0031] After the lower air supply component 7 briefly blows air onto the spherical catalyst carrier, causing it to flip, the lifting mechanism 8 resets both the upper and lower air supply components 7, while the sealing component 11 switches from the closed state back to the open state. This cycle repeats.

[0032] It should be noted that each time the lower air supply component 7 moves upward and closes, its air supply range can cover more than the width of two material spreading areas 6. Moreover, the interval between each upward movement of the lower air supply component 7 blowing the spherical catalyst on the mesh belt 3 is less than the time required for the mesh belt 3 to move horizontally to two material spreading areas 6, thereby ensuring that each set of lower air supply components 7 can turn over all the spherical catalyst carriers on the mesh belt 3.

[0033] See Figure 2 and Figure 5 The air supply assembly 7 includes a mounting base 71, on which multiple air supply nozzles 72 are fixedly mounted. A common air supply pipe is connected between the multiple air supply nozzles 72 on the same mounting base 71. Connecting shafts 73 are fixedly connected to both the left and right sides of the mounting base 71. The upper mounting base 71 is fixedly connected to two upper left and right connecting beams 9 via the connecting shafts 73 on both sides, while the lower mounting base 71 is connected to the corresponding variable-pitch guide assembly 10 via the connecting shaft 73. The air supply pipe is connected to an external hot air source to provide hot air; the specific selection can be based on the moisture content and particle size of the spherical catalyst carrier.

[0034] See Figure 2 and Figure 5 The lifting mechanism 8 includes two double-headed screws 81 rotatably mounted on the conveying frame 2 and distributed front to back. The same end of the upper and lower connecting beams 9 on the same side is threadedly connected to the corresponding double-headed screws 81 in opposite directions. A motor 82 is fixedly mounted on the conveying frame 2 near the upper end of the double-headed screws 81, and the output shaft of the motor 82 is fixedly connected to the upper end of the corresponding double-headed screw 81. The motor 82 drives the double-headed screws 81 to rotate, causing the upper and lower connecting beams 9 on the same side to move towards each other. This controls the upper sealing assembly 11 to move closer to the upper side of the material-carrying section of the mesh belt 3, while simultaneously controlling the lower air supply assembly 7 to move closer to the lower side of the material-carrying section of the mesh belt 3.

[0035] See Figure 2 and Figure 5 The variable-pitch guide assembly 10 includes a sliding sleeve 101 slidably fitted onto the lower connecting beam 9. The sliding sleeve 101 is fixedly connected to the connecting shaft 73 in the corresponding lower air supply assembly 7. Multiple sets of guide plate assemblies 102 are fixedly installed on both the left and right sides of the conveying frame 2. Each set of guide plate assemblies 102 consists of multiple guide plates with different inclination angles. The guide plate in the middle is vertical, and the multiple guide plates on both sides are symmetrically arranged with respect to the center line of the middle guide plate. The guide plates on both sides are inclined from top to bottom away from the middle guide plate. Strip-shaped guide holes are opened on the guide plates, and the connecting shaft 73 in the lower air supply assembly 7 is movably installed in the corresponding strip-shaped guide holes. An I-shaped guide wheel 103 is coaxially rotatably mounted on the surface of the connecting shaft 73, and the I-shaped guide wheel 103 is rolled in the strip-shaped guide hole. When the connecting beam 9 below moves upward under the drive of the double-headed screw 81, the air supply nozzle 72 on the mounting base 71 below moves upward through the sliding sleeve 101. At the same time, when the I-shaped guide wheel 103 moves upward, it abuts against the strip guide hole on the corresponding guide plate and rolls. The strip guide holes with different inclination angles abut against the corresponding I-shaped guide wheel 103, thereby causing the adjacent sliding sleeves 101 to move closer to each other and reduce the blowing range of the air supply nozzle 72. This ensures that the air supply nozzle 72 can generate enough wind power to drive the spherical catalyst carrier on the mesh belt 3 to roll without increasing the power of the external air source.

[0036] See Figure 5 and Figure 6The enclosed assembly 11 includes an outer frame 111 fixedly connected to the corresponding connecting beam 9 above via a connecting plate. Multiple enclosed baffles 112 are rotatably mounted inside the outer frame 111 via a rotating shaft. Drive assemblies 113 for driving the enclosed baffles 112 to rotate are mounted on both the front and rear sides of the outer frame 111. Each drive assembly 113 includes a transmission gear 1131 fixedly connected to one end of the rotating shaft. A slide rail is located on the upper side of the outer frame 111 near the transmission gear 1131. A drive toothed plate 1132, capable of sliding left and right, is slidably connected to the slide rail and meshes with the corresponding transmission gear 1131. An electric push rod 1133 is fixedly mounted on the outer frame 111 near the drive toothed plate 1132, with its telescopic end fixedly connected to the corresponding drive toothed plate 1132. The enclosed baffles 112 are in a vertical position, forming an air duct that guides hot air downwards towards the material. The enclosed baffle 112 is rotated to a horizontal position and spliced ​​into a nearly enclosed plane to prevent materials from jumping out.

[0037] Under normal conditions, the closed baffle 112 is in a vertical position and guides the hot air blown out by the upper air nozzle 72. When it is necessary to turn the spherical catalyst carrier on the mesh belt 3, the electric actuator 1133 controls the drive tooth plate 1132 to slide, thereby controlling the transmission gear 1131 to rotate, so that the originally vertical closed baffle 112 switches to a horizontal position. After all the closed baffles 112 in the outer shell 1 switch to a horizontal position, the lower side of all the closed baffles 112 and the lower side of the outer frame 111 together form a closed plane. The closed plane moves down and hangs at the upper end of the material laying area 6 on the mesh belt 3, preventing the spherical catalyst carrier from moving excessively during the tumbling process.

[0038] In this scheme, the conveyor belt 3 slowly conveys materials from front to back. After moving for a period of time, the two lifting mechanisms 8 operate synchronously, driving the upper and lower connecting beams 9 to move towards each other. The upper connecting beam 9 moves downward, causing the sealing component 11 to switch from an open state (at which time the sealing baffle 112 is vertical, acting as a guide) to a closed state (the sealing baffle 112 is horizontal, forming a closed plane), and finally descends to the upper end close to the material laying area 6 of the conveyor belt 3. At the same time, the lower connecting beam 9 moves upward, causing the lower air supply component 7 to move closer to the lower side of the material carrying section of the conveyor belt 3. During this process, the variable pitch guide component 10 causes the adjacent air supply components 7 to gradually move closer together, concentrating the air supply in a smaller area. This significantly improves the local air supply intensity without increasing the air source pressure.

[0039] A strong wind blows upwards, causing the spherical catalyst carriers in the spreading area 6 to tumble and adjust their positions. Due to the obstruction of the closed plane above, the spherical catalyst carriers can only move within a small range within the spreading area 6. This process helps to break up the accumulated spherical catalyst carriers and blows away those trapped in the mesh, facilitating the drainage of free moisture from the surface of the spherical catalyst carriers. After a brief period of strong wind tumbling, the lifting mechanism 8 drives the upper and lower components to reset, and the closed component 11 also returns to the open state. This cycle repeats continuously.
