[0002] Catalysts are core raw materials in industries such as chemical engineering, petroleum refining, nitrogen fertilizer, and environmental protection, and the drying process is crucial in their production. Catalyst drying equipment uses specific technologies to convert liquid or moist catalysts into dry powder or granular products to meet the needs of different industrial applications.
[0003] However, existing catalyst drying equipment uses external heating plates for heating and drying during actual use, which leads to uneven drying of the catalyst. The catalyst further away from the inner wall has a higher moisture content than the catalyst closer to the inner wall of the drying cylinder. To address this problem, a drying device for catalyst production is provided. Utility Model Content
[0004] The purpose of this utility model is to provide a drying device for catalyst production to solve the problems mentioned in the background art.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. By incorporating a vibration assembly, the moving plate drives the drying cylinder to vibrate at high speed under the limiting action of two fixed rods. This improves the uniformity of the catalyst within the drying cylinder, achieving catalyst agitation and further enhancing catalyst temperature uniformity. The reciprocating assembly allows the fixed frame to drive the fixed rods, moving plate, and drying cylinder to slide back and forth horizontally, causing the catalyst to swirl within the drying cylinder.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1 to 5 This utility model provides a technical solution: a drying device for catalyst production, including a base 1, a frame 2 at the top of the base 1, a reciprocating assembly inside the frame 2, a support 3 at the top of the reciprocating assembly, two fixed rods 4 at the top of the inner cavity of the support 3, a movable plate 5 slidably sleeved on the outer wall of the two fixed rods 4, a drying cylinder 6 at the top of the movable plate 5, and a fixed frame 7 at the bottom of the movable plate 5. A vibration assembly is installed inside the fixed frame 7. Through the vibration assembly, the movable plate 5 drives the drying cylinder 6 to vibrate at high speed under the limiting action of the two fixed rods 4, thereby improving the drying efficiency. The uniformity of the catalyst inside the drying cylinder 6 is improved by stirring the catalyst, which in turn improves the uniformity of the catalyst temperature. The reciprocating assembly allows the fixed frame 7 to drive the fixed rod 4, the moving plate 5, and the drying cylinder 6 to slide back and forth horizontally, which in turn agitates the catalyst inside the drying cylinder 6, further improving the uniformity of the catalyst temperature distribution. This solves the problem in existing catalyst drying equipment where external heating plates are used for heating and drying, resulting in uneven drying of the catalyst, with higher humidity of the catalyst further away from the inner wall than the catalyst closer to the inner wall of the drying cylinder 6.
[0021] In this embodiment, an anti-slip pad is provided at the bottom of the base 1, which can increase the friction between the device and the ground, prevent the device from moving during use, and improve the stability of the device during use.
[0022] In this embodiment, the vibration assembly includes a first motor 8, a rotating rod 9, and a rotating roller 10. The first motor 8 is located at the front end of the fixed frame 7, and its output end extends into the inner cavity of the fixed frame 7. One end of the rotating rod 9 is rotatably connected to the rear side of the inner cavity of the fixed frame 7 via a bearing, and the other end of the rotating rod 9 is fixedly connected to the output end of the first motor 8. The rotating roller 10 is fixedly sleeved on the outer wall of the rotating rod 9. When the first motor 8 is started, it drives the rotating roller 10 to rotate via the rotating rod 9. Since the rotating roller 10 is eccentrically located on the outer wall of the rotating rod 9, a corresponding centrifugal force is generated when the rotating roller 10 rotates. This causes the moving plate 5 to drive the drying cylinder 6 to vibrate under the limiting action of the fixed rod 4, which can improve the uniformity of the catalyst in the inner cavity of the drying cylinder 6, achieve stirring of the catalyst, and thus improve the uniformity of the catalyst temperature.
[0023] In this embodiment, the rotating roller 10 and the rotating rod 9 are eccentrically arranged, which can generate a corresponding eccentric force when the rotating rod 9 drives the rotating roller 10 to rotate. This causes the moving plate 5 to drive the drying cylinder 6 to vibrate under the limiting action of the fixed rod 4, which can improve the uniformity of the catalyst in the inner cavity of the drying cylinder 6, realize the stirring of the catalyst, and thus improve the uniformity of the catalyst temperature.
[0024] In this embodiment, springs 11 are provided on both the left and right sides of the outer walls of the two fixed rods 4, which can absorb some of the vibration energy and improve the stability of the equipment operation.
[0025] In this embodiment, the reciprocating assembly includes a second motor 12, a rotating column 13, a roller 14, a slide groove 15, guide rods 16, a sliding plate 17, and a slider 18. The second motor 12 is located at the right end of the frame 2, and its output end extends into the inner cavity of the frame 2. One end of the rotating column 13 is rotatably connected to the left side of the inner cavity of the frame 2 via a bearing, and the other end of the rotating column 13 is fixedly connected to the output end of the second motor 12. The roller 14 is fixedly sleeved on the outer wall of the rotating column 13, and the slide groove 15 is formed on the circumference of the outer wall of the roller 14. Both guide rods 16 are located in the inner cavity of the frame 2. The sliding plate 17 is slidably sleeved on the outer wall of the two guide rods 16 and fixedly connected to the bracket 3. The slider 18 is slidably embedded in the slide groove 15. The inner cavity is fixedly connected to the bottom end of the slide plate 17. The second motor 12 is started, which drives the slide groove 15 to rotate through the rotating column 13 and the roller 14. Since the slide groove 15 is spiral and connected end to end, when the slide groove 15 rotates, the slider 18 can drive the slide plate 17 to slide back and forth horizontally under the limiting action of the two guide rods 16, thereby agitating the catalyst in the inner cavity of the drying cylinder 6. This can further improve the uniformity of the catalyst temperature distribution and solve the problem that the existing catalyst drying equipment uses external heating plates for heating and drying in actual use, resulting in uneven drying of the catalyst, with the catalyst far from the inner wall having higher humidity than the catalyst near the inner wall of the drying cylinder 6.
[0026] In this embodiment, the slide 15 is spiral-shaped and connected end to end. When the slide 15 rotates, the slider 18 can drive the slide plate 17 to slide back and forth horizontally under the limiting action of the two guide rods 16.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
