Technical Field
[0001] This utility model relates to the field of baking soda processing, and in particular to a fluidized bed observation structure for baking soda drying. Background Technology
[0002] In existing technology, a sodium bicarbonate drying fluidized bed observation structure refers to a structural device installed on fluidized bed equipment during the sodium bicarbonate drying process to monitor the drying status and temperature changes of the sodium bicarbonate material inside the fluidized bed in real time. It typically consists of an observation window, temperature sensing elements, and related mounting and fixing components, and is an important auxiliary structure for ensuring the quality and efficiency of sodium bicarbonate drying.
[0003] In existing technologies, the process of using a sodium bicarbonate drying fluidized bed observation structure is roughly as follows: When sodium bicarbonate enters the fluidized bed for drying, the operator observes the fluidization state and degree of drying of the sodium bicarbonate material inside the fluidized bed through a transparent observation window on the observation structure. At the same time, the temperature detection element on the observation structure monitors the temperature inside the fluidized bed in real time and feeds the temperature data back to the relevant control system or display device. Based on the observed material state and temperature data, the operator adjusts the operating parameters of the fluidized bed, such as hot air temperature and wind speed, in a timely manner to ensure that the sodium bicarbonate achieves the expected drying effect.
[0004] In the use of existing technologies, after prolonged use, the inner wall of the observation window is prone to the accumulation of baking soda dust or other impurities, which leads to a decrease in observation clarity and affects the staff's accurate judgment of the internal material status. Therefore, based on the above-mentioned problems, a baking soda drying fluidized bed observation structure was developed. Utility Model Content

[0010] As a further description of the above technical solution: the outer wall of the inner rotating rod is fixedly connected to an inner slider, and the outer wall of the inner slider is slidably connected to the inner wall of the inner groove.

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 sodium bicarbonate drying fluidized bed observation structure, including a fluidized bed 1, which is the main drying site for sodium bicarbonate and provides space for the drying process. A cover plate 2 is provided on the top of the fluidized bed 1, covering the top of the fluidized bed 1 and providing a sealing function while also providing an installation position for a frame A3. The outer wall of the cover plate 2 is fixedly connected to the frame A3, which is used to install a cleaning mechanism 5, providing support and installation space for the cleaning mechanism 5. The cleaning mechanism 5 is installed inside the frame A3, used to clean the inner surface of the observation plate 512 to ensure observation effectiveness. The cleaning mechanism 5 includes an observation plate 512 slidably connected to the inner wall of a frame B511, which provides a track for the sliding of the observation plate 512 and also supports the support A5. 13. Components such as the circular frame 515, with a bracket A513 fixedly connected to the outer wall of the frame B511. The bracket A513 is used to fix the brush plate 514, keeping it in a suitable position for cleaning the observation plate 512. The brush plate 514 is fixedly connected to the outer wall of the bracket A513. When the observation plate 512 rotates, the brush plate 514 contacts the outer wall of the observation plate 512 to clean its inner wall and remove dust and impurities. A circular frame 515 is fixedly connected to the outer wall of the frame B511, providing an insertion channel for the magnetic insertion rod 5112 to fix the inner rotating rod 518. An outer rotating rod 516 is rotatably connected to the inner wall of the frame B511. The outer rotating rod 516 can rotate on the inner wall of the frame B511 to transmit the rotational force of the inner rotating rod 518 to the gears. A517, gear A517 is fixedly connected to the extended end of the outer rotating rod 516. When gear A517 meshes with the tooth groove on the outer wall of the observation plate 512, it drives the observation plate 512 to rotate. The observation plate 512 is equipped with a flipping mechanism 6. The observation plate 512 is transparent to facilitate observation of the drying status of sodium bicarbonate inside the fluidized bed 1. When rotating, it can cooperate with the brush plate 514 to complete cleaning and drive the flipping mechanism 6 to operate. The flipping mechanism 6 includes a rotating shaft 611, which is the rotation center of the flipping mechanism 6 and drives gear B612 and circular plate 619 to rotate. The outer wall of the rotating shaft 611 is rotatably connected to the inner wall of the observation plate 512. Gear B612 is fixedly connected to the inner extended end of the rotating shaft 611 near the observation plate 512. Gear B612 meshes with rack 618 when observing... When plate 512 rotates, it moves and rotates along rack 618, thereby driving shaft 611 to rotate. Temperature sensors A613 and B614 are fixedly connected to both sides of gear B612. Temperature sensor A613 is initially located on the inner side to detect the internal temperature of fluidized bed 1. After being flipped, it moves to the outer side for cleaning. Temperature sensor B614 is initially located on the outer side and, after being flipped, moves to the inner side to replace temperature sensor A613 in detecting temperature, preventing temperature sensor A613 from becoming clogged and affecting detection. A bracket B615 is fixedly connected to the outer wall of frame B511. Bracket B615 provides installation and sliding support for rack 618, bolts 617, and limit rod 616 to ensure the stability of rack 618. Rack 618 is slidably connected to the inner wall of frame B511.The rack 618 meshes with gear B612, providing power for the rotation of gear B612. Its position is adjustable via bolt 617 to ensure proper meshing with gear B612. Bolt 617 is fixedly connected to the outer wall of the rack 618, passing through bracket B615 to fix the position of the rack 618. The position of the rack 618 is adjusted by tightening or loosening the bolt. The outer wall of bolt 617 is threaded into the inner wall of bracket B615. A limit rod 616 is fixedly connected to the outer wall of the rack 618. The limit rod 616 slides within bracket B615, restricting the movement direction of the rack 618 and preventing it from deviating. The outer wall of the limit rod 616 is slidably connected to the inner wall of bracket B615.
[0020] Reference Figures 3-5 The inner wall of the outer rotating rod 516 has an inner groove 5111. The inner groove 5111 allows the inner slider 519 to slide, enabling the inner rotating rod 518 to drive the outer rotating rod 516 to rotate, while also allowing the inner rotating rod 518 to move axially. The inner rotating rod 518 is slidably connected to the inner wall of the outer rotating rod 516. When the inner rotating rod 518 rotates, it drives the outer rotating rod 516 to rotate through the inner slider 519 and the inner groove 5111. The magnetic insertion rod 5112 can be inserted into its through hole for fixation. The outer wall of the inner rotating rod 518 is fixedly connected to the inner slider 519. The inner slider 519 is embedded in the inner groove 5111, transmitting the rotational force of the inner rotating rod 518 to the outer rotating rod 516, and moving axially with the inner rotating rod 518. The outer wall of the inner slider 519 is slidably connected to the inner wall of the inner groove 5111. The outer wall of the circular frame 515 is inserted with the magnetic insertion rod 5112, which is inserted into the inner rotating rod 518. After the through hole, the inner rotating rod 518 is fixed and limited to prevent it from rotating arbitrarily. A magnetic insertion rod 5112 is inserted into the outer wall of the circular frame 515. The outer wall of the inner rotating rod 518 has a through hole for the magnetic insertion rod 5112 to be inserted and cooperate with the magnetic insertion rod 5112 to fix the inner rotating rod 518. The extension end of the magnetic insertion rod 5112 is inserted into the inner wall of the through hole. The outer wall of the observation plate 512 has a toothed groove, which meshes with the gear A517. When the gear A517 rotates, it drives the observation plate 512 to rotate. The outer wall of the gear A517 meshes with the toothed groove on the outer wall of the observation plate 512. The outer wall of the brush plate 514 contacts the outer wall of the observation plate 512. The circular plate 619 on the outer wall of the rotating shaft 611 rotates and flips, causing the temperature sensor A613 and the temperature sensor B614 to switch positions, realizing the alternating use and cleaning of the two.
[0021] Working principle: A cover plate 2 is installed on the top of the fluidized bed 1. A frame is installed on the outer wall of the cover plate 2, and a cleaning mechanism 5 is installed inside the frame. An observation plate 512 is slidably connected to the inner wall of the frame. The observation plate 512 is transparent to facilitate observation of the drying status of the baking soda inside. After prolonged use, the inner surface of the observation plate 512 will be obscured by dust and impurities. When the observation plate 512 needs to be cleaned, the operator first pulls out the magnetic insertion rod 5112 and then rotates the inner rotating rod. 518, the inner rotating rod 518 drives the outer rotating rod 516 to rotate, which in turn drives the gear A517 to rotate. When the gear A517 rotates, it drives the observation plate 512 to rotate. When the observation plate 512 rotates, it contacts the outer wall of the brush plate 514, so that the brush plate 514 brushes along the outer wall of the observation plate 512 to clean the inner surface of the observation plate 512. After cleaning, the magnetic insertion rod 5112 is inserted into the outer wall of the inner rotating rod 518 to fix and limit the inner rotating rod 518. Meanwhile, a flipping mechanism 6 is provided on the frame. A rack 618 is slidably connected to the inner wall of the frame, and the rack 618 is threaded to the outer wall of the frame. When the observation plate 512 rotates one revolution to clean the inner surface, it drives the gear B612 on the rotating shaft 611 inside the observation plate 512 to move along the rack 618. When the gear B612 meshes with the rack 618, it drives the gear B612 on the outer wall of the rotating shaft 611 to rotate. Thus, when the observation plate 512 rotates one revolution, it drives the circular plate 619 on the outer wall of the rotating shaft 611 to flip one revolution, thereby exchanging the positions of the temperature sensor B614 on the outer surface and the temperature sensor A613 on the inner surface. This allows the internal temperature sensor A613 to be flipped out for timed cleaning, preventing the temperature sensor A613 from being blocked during baking soda processing and affecting the drying 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.
