Description

Technical Field

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

[0002] Catalysts are generally substances that can increase the rate of a chemical reaction without changing the chemical equilibrium, and whose mass and chemical properties remain unchanged before and after the chemical reaction. Based on their form, they are mainly divided into liquid catalysts and solid catalysts.

[0003] In order to increase the contact area between the reactants and the catalyst and improve the catalytic effect, solid catalysts are usually made into granules during use. During the production process, solid catalysts are made into the required granules after a molding process. Then, these granular catalysts need to be thoroughly dried to remove the moisture attached to their surface. In order to improve the drying efficiency, a drying device is generally used for drying.

[0004] For example, CN222165515U discloses a catalyst material dryer, relating to the technical field of drying equipment for catalyst production. It includes a base plate, with a hot air device and a vertical plate fixedly mounted on the top of the base plate. A geared motor is fixedly connected to the front of the vertical plate, and the output shaft of the geared motor passes through the vertical plate and is fixedly connected to a rotating shaft. A rotating box is fixedly connected to the rear end of the rotating shaft. The left and right sides of the rotating box are hollowed out. The air outlet of the hot air device is aligned with the right side of the rotating box. Several partitions, which are also hollowed out, are fixedly connected from left to right between the front and rear inner walls of the rotating box. The technical problem solved by this invention is to improve the drying process efficiency.

[0005] However, in actual use, the above technology requires uniform feeding during drying and the machine needs to be stopped before the dried catalyst is unloaded. It is not convenient to automatically feed and unload the catalyst, and cannot achieve automatic continuous drying. Utility Model Content

[0007] Drying equipment for catalyst production includes:

[0008] A drying oven, wherein a fixing frame is fixedly provided on the inner wall of the drying oven;

[0009] A feeding assembly is set at the top of the fixed frame. The feeding assembly includes a guide rail fixedly connected to the top of the fixed frame. A connecting rod that moves along the direction of the guide rail is provided on the guide rail. A toothed column is rotatably connected to the bottom of the connecting rod through a bearing. A holding box for holding catalyst is fixedly connected to the bottom of the toothed column, so that the connecting rod drives the holding box to move in and out of the drying box along the direction of the guide rail through the toothed column.

[0010] A drive assembly is provided at the bottom of the guide rail. The drive assembly includes a drive column rotatably connected to the middle of the drying chamber via a bearing. A drive wheel is rotatably connected to the surface of the drive column corresponding to the toothed column position via a bearing. A transmission belt is provided at the bottom of the guide rail. The toothed column is located between the transmission belt and the drive wheel, and the surface of the drive wheel is provided with teeth, so that the drive wheel and the transmission belt can move relative to each other and drive the container to rotate through the toothed column, thereby achieving uniform drying.

[0011] An electric heating tube is fixedly installed in the middle of the fixed frame corresponding to the position of the drive column.

[0012] Preferably, the guide rail has a hollow structure in the middle, and a guide wheel is fixedly connected to the top of the connecting rod. The guide wheel is rotatably connected to the inner wall of the guide rail so that the guide wheel cooperates with the guide rail to guide the movement of the connecting rod. One end of the guide rail has a semi-circular structure and is located inside the drying oven, and the guide rail can move through and extend to the outside of the drying oven.

[0013] Preferably, a chain is fixedly connected to the bottom of the connecting rod, a sprocket is fixedly connected to the surface of the drive column corresponding to the drive column position, and the sprocket is connected to the chain drive. The drive column is driven by a drive motor.

[0014] Preferably, the bottom of the guide rail is fixedly connected to an outer protective frame for protecting and guiding the connecting rod, both ends of the transmission belt are respectively connected to drive rollers, the top of the drive rollers is fixedly connected to a drive shaft, and the drive shaft is rotatably connected to the middle of the outer protective frame through a bearing, and the transmission belt has an arc-shaped structure.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model uses a connecting rod that moves along the guide rail to drive the container into the drying box via a toothed column. When the container enters the drying box, the electric heating tube generates heat and dries the catalyst inside the container. By controlling the time when the container enters the drying box, the container can be moved out of the drying box after drying, thus achieving automatic material discharge and enabling automatic continuous loading and unloading.

[0019] This invention also features a mechanism where, when the toothed column moves the container to the position between the transmission belt and the drive wheel, the rotation of the sprocket causes the first toothed ring to rotate, which in turn drives the second toothed ring to rotate in the opposite direction via the transmission gear. This causes the second toothed ring to drive the drive wheel to rotate in the opposite direction to the sprocket. Simultaneously, because the toothed column is located between the transmission belt and the drive wheel and is tightly fitted between them, when the drive wheel rotates, it drives the toothed column to rotate, causing the transmission belt to rotate in the opposite direction to the drive wheel. This ensures that all the toothed columns fitted between the transmission belt and the drive wheel are driven to rotate, thereby causing the toothed column to rotate the container. This ensures that the catalyst inside the container is evenly dried by the electric heating element, preventing uneven drying. Attached Figure Description

[0029] 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.

[0030] Please see Figure 1-8 This utility model provides a technical solution: a drying device for catalyst production, comprising:

[0031] Drying oven 1, with a fixed frame 2 fixedly installed on the inner wall of drying oven 1;

[0032] A feeding assembly is installed at the top of the fixed frame 2. The feeding assembly includes a guide rail 3 fixedly installed at the top of the fixed frame 2. A connecting rod 5 is provided on the guide rail 3 and moves along the direction of the guide rail 3. The bottom of the connecting rod 5 is rotatably connected to a toothed column 7 through a bearing. A container 8 for holding catalyst is fixedly installed at the bottom of the toothed column 7 so that the connecting rod 5 drives the container 8 to move in and out of the drying chamber 1 along the direction of the guide rail 3 through the toothed column 7. The guide rail 3 has a hollow structure in the middle. A guide wheel 4 is fixedly installed at the top of the connecting rod 5 and is rotatably connected to the inner wall of the guide rail 3 so that the guide wheel 4 cooperates with the guide rail 3 to guide the movement of the connecting rod 5. One end of the guide rail 3 has a semi-circular structure and is located inside the drying chamber 1. The guide rail 3 can move through and extend to the outside of the drying chamber 1.

[0033] A chain 6 is fixedly installed at the bottom of the connecting rod 5, and a sprocket 10 is fixedly installed on the surface of the drive column 9 corresponding to the position of the drive column 9. The sprocket 10 is connected to the chain 6 for transmission, and the drive column 9 is driven by a drive motor.

[0034] When the above structure is in use, the drive motor drives the drive column 9 to rotate, which in turn drives the sprocket 10 to rotate. When the sprocket 10 rotates, it drives the chain 6 to transmit power.

[0035] A drive assembly is located at the bottom of the guide rail 3. The drive assembly includes a drive column 9 rotatably connected to the middle of the drying chamber 1 via bearings. An electric heating tube 20 is fixedly installed at the middle of the fixed frame 2 corresponding to the position of the drive column 9. A drive wheel 16 is rotatably connected to the surface of the drive column 9 corresponding to the position of the toothed column 7 via bearings. A transmission belt 14 is provided at the bottom of the guide rail 3. The toothed column 7 is located between the transmission belt 14 and the drive wheel 16, and the surface of the drive wheel 16 is provided with teeth so that the drive wheel 16 and the transmission belt 14 can move relative to each other and drive the holding chamber 8 through the toothed column 7. The rotation achieves uniform drying. The bottom of the guide rail 3 is fixedly installed with an outer protective frame 11 for protecting and guiding the connecting rod 5. Both ends of the transmission belt 14 are respectively connected to drive rollers 13. The top of the drive roller 13 is fixedly installed with a drive shaft 12, and the drive shaft 12 is rotatably connected to the middle of the outer protective frame 11 through bearings. The transmission belt 14 has an arc-shaped structure. The bottom of the outer protective frame 11 is fixedly installed with two support frames 15, and the two support frames 15 are respectively located at both ends of the inner wall of the transmission belt 14 to shape the support frames 15.

[0036] In use, the toothed column 7 is positioned between the transmission belt 14 and the drive wheel 16, and the toothed column 7 is tightly fitted between the transmission belt 14 and the drive wheel 16. When the drive wheel 16 rotates, it will drive the toothed column 7 to rotate, and the toothed column 7 will drive the transmission belt 14 to rotate in the opposite direction to the rotation of the drive wheel 16. This ensures that all the toothed columns 7 fitted between the transmission belt 14 and the drive wheel 16 will be driven to rotate, thereby causing the toothed column 7 to drive the container 8 to rotate. This allows the catalyst in the container 8 to be dried evenly by the electric heating tube 20, avoiding uneven drying.

[0037] A first toothed ring 17 is fixedly installed at the center of the bottom of the sprocket 10. A transmission gear 18 meshes with the surface of the first toothed ring 17. The transmission gear 18 is rotatably connected to the surface of the fixed frame 2 through a bearing bracket. A second toothed ring 19 meshes with the surface of the transmission gear 18. The second toothed ring 19 is fixedly installed on the top of the drive wheel 16.

[0038] When the above structure is in use, the sprocket 10 rotates, which drives the first toothed ring 17 to rotate, and the first toothed ring 17 drives the second toothed ring 19 to rotate in the opposite direction through the transmission gear 18, thereby causing the second toothed ring 19 to drive the drive wheel 16 to rotate in the opposite direction to the sprocket 10.

[0039] The working principle of this utility model is as follows: In use, the toothed column 7 is fixed to the holding box 8, and then the drive motor drives the drive column 9 to rotate, which in turn drives the sprocket 10 to rotate. When the sprocket 10 rotates, it drives the chain 6 to transmit power, and the chain 6 drives the connecting rod 5 to move. The guide wheel 4, in conjunction with the guide rail 3, limits the movement of the connecting rod 5. When the chain 6 drives the connecting rod 5, the connecting rod 5 moves along the direction of the guide rail 3, and the connecting rod 5 drives the holding box 8 into the drying box 1 through the toothed column 7. When the holding box 8 enters the drying box 1, the electric heating tube 20 generates heat and dries the catalyst in the holding box 8. By controlling the time when the holding box 8 enters the drying box 1, the holding box 8 can be removed from the drying box 1 after drying, thus achieving automatic unloading. This realizes automatic and continuous loading and unloading. The purpose is to ensure that when the toothed column 7 moves the container 8 to the position between the transmission belt 14 and the drive wheel 16, the rotation of the sprocket 10 will cause the first toothed ring 17 to rotate, which in turn causes the second toothed ring 19 to rotate in the opposite direction via the transmission gear 18. This, in turn, causes the second toothed ring 19 to cause the drive wheel 16 to rotate in the opposite direction to the sprocket 10. Since the toothed column 7 is located between the transmission belt 14 and the drive wheel 16, and is tightly fitted between them, when the drive wheel 16 rotates, it will cause the toothed column 7 to rotate, causing the transmission belt 14 and the drive wheel 16 to rotate in opposite directions. This ensures that all the toothed columns 7 fitted between the transmission belt 14 and the drive wheel 16 are driven to rotate, thereby causing the container 8 to rotate. This allows the catalyst inside the container 8 to be evenly dried by the electric heating tube 20, preventing uneven drying.
