Description

Technical Field

[0001] This utility model relates to the field of baking soda processing, and in particular to a porous gas distribution plate for drying baking soda in a fluidized bed. Background Technology

[0002] The porous gas distribution plate in a fluidized bed for baking soda drying is a key equipment component used in the baking soda drying process. Its main function is to achieve uniform distribution of drying gas within the fluidized bed, ensuring sufficient contact between the baking soda and the drying gas to achieve the desired drying effect.

[0003] In practical applications, baking soda is typically placed in a fluidized bed. Drying gas is introduced from below a distribution plate, dispersed through pores in the plate into the fluidized bed, and exchanges heat with the baking soda particles to remove moisture and achieve drying. Operators, based on experience or established procedures, start the relevant equipment to deliver the drying gas and use simple adjustment devices to initially set parameters such as the gas flow rate on the distribution plate to maintain the continuous drying process.

[0004] In practical applications, the adjustment structure of the porous gas distribution plate in the fluidized bed for baking soda drying is relatively simple, making it difficult to meet the needs of uniform drying parameter adjustment for baking soda in different areas during large-scale production, and preventing synchronous adjustment of multiple distribution plates. This results in inconsistent drying degrees of baking soda at different locations during actual operation, seriously affecting the overall product quality. Therefore, the porous gas distribution plate for the fluidized bed for baking soda drying was developed to address the aforementioned issues. Utility Model Content

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.

[0019] Reference Figures 1-3This utility model provides an embodiment of a porous gas distribution plate for a sodium bicarbonate drying fluidized bed, comprising a fluid bed 1. The fluid bed 1 provides a supporting foundation for the entire device and is the main structure for accommodating the sodium bicarbonate for drying. A distribution plate 2 is fixedly connected to the top of the fluid bed 1. The distribution plate 2 is used to control the gas distribution. The airflow size is adjusted through the pores of the distribution plate 2, thereby affecting the drying effect of the sodium bicarbonate. A transmission mechanism 3 is provided inside the distribution plate 2. The transmission mechanism 3 is a key structure for adjusting the size of the pores of the distribution plate 2. The transmission mechanism 3 includes an outer transmission shaft 311, which serves as a transmission component and is rotatably connected to the inner wall of the distribution plate 2, providing a rotational foundation for subsequent components. The outer wall of the outer transmission shaft 311 is rotatably connected to the inner wall of the distribution plate 2. A gear 312 is fixedly connected to the extended end of the transmission outer shaft 311. The gear 312 transmits power during transmission and meshes with the gear plate 314 to drive related components. A limit rod 313 is fixedly connected to the outer wall of the fluid bed 1. The limit rod 313 restricts the movement direction of the gear plate 314, ensuring the stability of its movement. The gear plate 314 is slidably connected to the outer wall of the limit rod 313. The gear plate 314 moves to drive the gear 312 to rotate, thereby adjusting the size of the air holes in the distribution plate 2. A rectangular insert rod 315 is slidably connected to the bottom of the gear plate 314. The rectangular insert rod 315 helps to fix the position of the gear plate 314, enabling synchronous operation of adjusting multiple sets of air holes in the distribution plate 2. The top of the gear plate 314 is flush with the outer wall of the gear 312. The transmission mechanism 3 is internally equipped with an opening and closing mechanism 4, which controls the opening and closing state of the airflow holes in the distribution plate 2. A cover plate A3111 is fixedly connected to the outer wall of the transmission outer shaft 311. The cover plate A3111 directly adjusts the size of the airflow holes in the distribution plate 2 to control the airflow. A wing bolt A317 is threadedly connected to the outer wall of the toothed plate 314 to fix the toothed plate 314 and prevent accidental movement. A connecting plate 318 is fixedly connected to the bottom of the toothed plate 314, providing an installation position for the wing bolt B319 and assisting in fixing the toothed plate 314. The wing bolt B319 is threadedly connected to the outer wall of the connecting plate 318. The wing bolt B319 and the wing bolt A317 work together to stabilize the toothed plate 314. Fixed to the outer wall of fluid bed 1, the extended ends of both wing bolts B319 and A317 abut against the outer wall of fluid bed 1. There are two sets of transmission mechanisms 3, symmetrically arranged at the left and right ends of the distribution plate 2, making the air hole adjustment operation of the distribution plate 2 more flexible and convenient. The inner wall of the second set of gears 312 is fixedly connected to the extended end of the transmission inner shaft 411, which can drive the connected components to rotate, realizing different opening and closing controls of the air holes of the distribution plate 2. There are three distribution plates 2, symmetrically installed at equal intervals on the top of fluid bed 1, expanding the gas distribution range and improving the drying efficiency of baking soda. The inner wall of the middle toothed plate 314 has a rectangular groove for accommodating the rectangular insert rod 315.To achieve synchronous adjustment of multiple distribution plates 2, the outer wall of the rectangular insertion rod 315 is rectangular, and a handle 316 is fixedly connected to the bottom of the rectangular insertion rod 315. The outer wall of the rectangular insertion rod 315 is adapted to the rectangular groove opened in the inner wall of the toothed plate 314, ensuring that the rectangular insertion rod 315 can be stably inserted into the rectangular groove, thus achieving synchronous adjustment of multiple distribution plates 2.

[0020] Reference Figures 1-3 The opening and closing mechanism 4 includes an inner drive shaft 411, which acts as a transmission component, driving the connected cover plate B412 to move. The outer wall of the inner drive shaft 411 is rotatably connected to the inner wall of the outer drive shaft 311. A rectangular block 413 is fixedly connected to the outer wall of the inner drive shaft 411, connecting the inner drive shaft 411 and the cover plate B412 and transmitting rotational power. The extended end of the rectangular block 413 is fixedly connected to the cover plate B412, which is used for complete closure. The airflow holes of plate 2, or in conjunction with cover plate A3111, control the airflow. The bottom of the transmission outer shaft 311 is provided with an annular through groove, which provides a sliding track for rectangular block 413, ensuring that cover plate B412 can move along a specific trajectory. The outer surface of rectangular block 413 is slidably connected to the outer wall of the through groove, and the outer wall of cover plate B412 is magnetically connected to the outer wall of cover plate A3111, which facilitates flexible adjustment of the opening and closing degree of the airflow holes according to actual drying needs. The outer wall of fluid bed 1 is fixedly connected with air inlet 5.

[0021] Working principle: A distribution plate 2 is installed on the top of the fluid bed 1. A transmission mechanism 3 is set on the outside of the distribution plate 2. A transmission outer shaft 311 is rotatably connected to the inner wall of the distribution plate 2. A gear 312 is installed at the extension end of the transmission outer shaft 311. When it is necessary to adjust the size of the air holes of the distribution plate 2, the operator moves the toothed plate 314. When the toothed plate 314 moves, it drives the gear 312 meshing at the top to rotate. When the toothed plate 314 rotates, it drives the opening and closing adjustment of the cover plate A3111. At the same time, a rectangular insert rod 315 is slidably connected to the bottom of the toothed plate 314. When the size of the air holes in the other distribution plates 2 needs to be adjusted synchronously, the rectangular insert rods 315 at the front and rear ends are inserted into the middle insert plate to fix the toothed plate 314 and realize the synchronous adjustment of the opening and closing plates in the three sets of distribution plates 2. Then, the adjusted toothed plate 314 and the rectangular insert rod 315 are fixed by the wing bolts A317 and B319. When the airflow holes in the distribution plate 2 need to be closed, the transmission mechanism 3 at the other end of the distribution plate 2 is rotated. The transmission mechanism 3 at the other end controls the inner transmission shaft 411 to rotate. When the inner transmission shaft 411 is rotated, the cover plate B412 moves along the annular groove at the bottom of the outer transmission shaft 311, thereby controlling the cover plate B412 to close the entire airflow hole. When it is not necessary to close it completely, the cover plate B412 is magnetically connected to the bottom of the cover plate A3111. The size of the airflow holes in the distribution plate 2 is mainly controlled by the cover plate A3111 to control the size of the drying airflow according to the drying requirements of baking soda.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
