Description

Technical Field

[0001] The present invention relates to the technical field of drying, and specifically to a sodium perborate drying device. Background Art

[0002] Sodium perborate is a white crystalline powder that is easily soluble in water and is commonly used in detergents, bleaching agents, and disinfectants. In industrial production, drying is a key step in its preparation process, and temperature, humidity, and stability need to be strictly controlled. In order to improve the drying effect of sodium perborate, a fluidized bed dryer is mostly used to dry sodium perborate.

[0003] However, the main component of the fluidized bed dryer is the gas distribution plate, which directly affects the fluidization effect, drying uniformity, and energy consumption. Since a large number of holes are provided on the surface of the gas distribution plate, although the diameter of these holes is smaller than the diameter of the material particles to prevent material blockage, the material is in a wet state before entering the dryer and has a certain viscosity, making it easy to stick to the surface of the gas distribution plate. Over time, a large amount of material will stick to the surface of the gas distribution plate, covering the holes and thus affecting the normal flow of air.

[0004] Therefore, we propose a sodium perborate drying device. Summary of the Invention

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0033] Embodiment 1

[0034] Please refer to Figure 1-11 , the present invention provides a technical solution: a sodium perborate drying device, including a machine body 1, the inner surface of the machine body 1 is fixedly connected with a gas distribution plate 10, the outer surface of the machine body 1 is fixedly connected with a vibrator 13, the outer surfaces on both sides of the machine body 1 are fixedly connected with air inlet pipes 11 below the gas distribution plate 10, and the upper outer surface of the machine body 1 is fixedly connected with an air outlet pipe 12;

[0035] A cleaning plate 20, the cleaning plate 20 is attached to the upper outer surface of the gas distribution plate 10, and the width and length of the cleaning plate 20 are the same as those of the gas distribution plate 10. The cleaning plate 20 slides along the gas distribution plate 10 to clean the materials adhered to the surface of the cleaning plate 20, preventing the gas distribution plate 10 from being covered by materials and causing air circulation blockage;

[0036] A driving assembly 2, the driving assembly 2 is located above the cleaning plate 20 and can convert the vertical vibration of the vibrator 13 into the horizontal movement of the cleaning plate 20, so that the cleaning plate 20 moves and scrapes along the gas distribution plate 10, making full use of the vibration generated by the vibrator 13, so that this anti-blocking method can be started when the equipment dries the materials, improving the anti-blocking efficiency.

[0037] The driving assembly 2 includes an upper tooth plate 26, which is arranged on one side of the inner surface of the body 1. The lower end of the upper tooth plate 26 is meshed with a gear set 3, and one side of the gear set 3 is meshed with a counterweight block 24, and the surface of the counterweight block 24 is fixedly connected with teeth 25. The angle between the counterweight block 24 and the upper tooth plate 26 is 90 degrees, which divides the vertical movement of the counterweight block 24 and the lateral movement of the cleaning plate 20. One side of the gear set 3 is connected to a connecting plate 21 through a rotating shaft, and the connecting plate 21 is fixedly connected to the cleaning plate 20. A connecting groove is provided on the upper end of the connecting plate 21. 211, a bending rod 23 is slidably connected inside the connecting groove 211 to limit the direction of movement of the counterweight 24 so that it can only move up and down. A locking piece can be added to the bending rod 23 and the connecting groove 211 to prevent the counterweight 24 and the bending rod 23 from being separated from the limit of the connecting groove 211. The bending rod 23 is fixedly connected to the counterweight 24. When the vibrator 13 is started, the body 1 will vibrate up and down to shake the material on the surface of the gas distribution plate 10 away from the gas distribution plate 10. At this time, dry high-temperature air is introduced through the air inlet pipe 11 to dry the suspended material.

[0038] The bending rod 23 is bent at 90 degrees, and the end of the bending rod 23 away from the connecting groove 211 is fixedly connected to the counterweight block 24 near the upper end, so that it can be better connected to the counterweight block 24. The side surface of the connecting plate 21 fits the inner surface of the body 1, and the connecting plate 21 is located between the upper tooth plate 26 and the body 1 to prevent the counterweight block 24 from interfering with the upper tooth plate 26.

[0039] The gear set 3 includes a first gear 30 and a second gear 31. The first gear 30 meshes with the upper toothed plate 26, and the second gear 31 meshes with the counterweight 24. One side of the first gear 30 is rotatably connected to the connecting plate 21 through a rotating shaft. On the other side of the first gear 30, a ratchet groove 34 is formed. Inside the ratchet groove 34, a rotating rod 32 is rotatably connected through a rotating shaft. One end of the rotating rod 32 away from the ratchet groove 34 is fixedly connected to the second gear 31. On the surface of the rotating rod 32, an elastic plate 33 with an arc-shaped structure is fixedly connected. The elastic plate 33 is engaged with the ratchet groove 34 through elastic deformation. The thickness of the first gear 30 is the same as that of the upper toothed plate 26, and the thickness of the second gear 31 is the same as that of the counterweight 24. The diameters of the first gear 30 and the second gear 31 can be changed according to different usage situations. The length of the auxiliary plate 28 needs to be adjusted synchronously to achieve different transmission ratios to meet different usage situations. When the counterweight 24 moves upward, the second gear 31, the rotating rod 32, and the flap rotate forward. At this time, the elastic plate 33 contacts the ratchet groove 34, and the ratchet groove 34 does not hinder the rotation of the elastic plate 33. At this time, the first gear 30 is in a static state. When the counterweight 24 moves downward, the second gear 31 rotates in the reverse direction. At this time, the elastic plate 33 will snap into the inner surface of the ratchet groove 34, thereby driving the first gear 30 to rotate in the reverse direction as well. The reverse rotation of the first gear 30 cooperates with the upper toothed plate 26, forcing the first gear 30 and the connecting plate 21 to move along the gas distribution plate 10. At this time, the cleaning plate 20 will move along the gas distribution plate 10 to scrape the surface of the gas distribution plate 10 to prevent materials from accumulating on the surface of the gas distribution plate 10;

[0040] Both ends of the upper toothed plate 26 are fixedly connected with auxiliary plates 28. On the side of the auxiliary plate 28 away from the upper toothed plate 26, a lower toothed plate 27 is fixedly connected. The lower toothed plate 27 corresponds to the gear. A rectangular frame is formed by the upper toothed plate 26, the lower toothed plate 27, and the auxiliary plates 28. At the corresponding position of the surface of the machine body 1 and the auxiliary plate 28, a telescopic groove 41 is formed. Inside the telescopic groove 41, a stopper 40 is slidably connected. The stopper 40 is fixedly connected to the auxiliary plate 28. The stopper 40 is fixedly connected to the auxiliary plate 28. At the upper and lower ends of the inner surface of the telescopic groove 41, electromagnets 42 are fixedly connected. The stopper 40 is made of a magnetic material. The electromagnet 42 can adsorb the stopper 40 through magnetic force, forcing the entire rectangular frame to move upward, increasing the stability of the entire structure. At this time, it forces the lower toothed plate 27 to mesh with the first gear 30. When the counterweight 24 moves up and down, it will control the connecting plate 21 and the cleaning plate 20 to move in the opposite direction. Through the above structure, the reciprocating movement of the cleaning plate 20 can be realized, and the cleaning efficiency can be improved compared with manual cleaning.

[0041] Embodiment 2

[0042] On one side of the auxiliary plate 28 close to the connecting plate 21, a wedge block 29 is fixedly connected. At the position of the connecting plate 21 corresponding to the inclined surface of the wedge block 29, a push rod 22 is fixedly connected. On the side of the auxiliary plate 28 away from the wedge block 29, a slider 45 is fixedly connected. At the position of the machine body 1 corresponding to the slider 45, a chute 44 is provided. The slider 45 is located inside the chute 44. On the upper and lower sides of the inner surface of the chute 44, magnetic attraction blocks 46 are fixedly connected. The magnetic attraction blocks 46 and the slider 45 can be magnetically attracted. Different from Embodiment 1, when the connecting plate 21 and the cleaning plate 20 move a certain distance, the push rod 22 will contact the inclined surface of the wedge block 29. As the connecting plate 21 and the first gear 30 continue to move, the push rod 22 jacks up the wedge block 29. The distance between the upper toothed plate 26 and the lower toothed plate 27 is slightly larger than the diameter of the first gear 30, reducing the vacuum period when the first gear 30 switches between the upper toothed plate 26 and the lower toothed plate 27. The magnetic attraction blocks 46 and the slider 45 are magnetically attracted. The slider 45 is made of magnetically attracted metal, which can increase the stability of the upper toothed plate 26 and the lower toothed plate 27. The auxiliary plate 28, the upper toothed plate 26 and the lower toothed plate 27 can be made of carbon fiber material to reduce the weight. At the same time, sufficient friction is maintained between the auxiliary plate 28 and the machine body 1 to prevent the vibrator 13 from changing the position of the auxiliary plate 28.

[0043] The push rod 22 includes a main rod 221 and a sub-rod 222. One end of the main rod 221 is fixedly connected to the connecting plate 21, and the auxiliary plate 28 can slide along the main rod 221. One end of the sub-rod 222 close to the main rod 221 is fixedly connected to a displacement rod 52. A displacement groove 50 for the displacement rod 52 to slide is provided inside the main rod 221. A spring 51 is fixedly connected between the displacement rod 52 and the displacement groove 50. A triangular prism rod 55 is embedded in the connection gap between the main rod 221 and the sub-rod 222. At the position of the machine body 1 corresponding to the triangular prism, a baffle 43 is fixedly connected. In order to further reduce the existence of the vacuum period, when the push plate moves to the moving distance, the triangular prism will contact the baffle 43, thereby forcing the triangular prism rod 55 to squeeze the sub-rod 222. The actual moving speed of the sub-rod 222 will be greater than the moving speed of the main rod 221. When the end of the sub-rod 222 contacts the wedge block 29, it will push the upper toothed plate 26 and the lower toothed plate 27 to move faster, improving the operating efficiency of the equipment.

[0044] One side of the triangular prism is fixedly connected with a limit block 54. A limit groove 53 is provided at the position of the main rod 221 corresponding to the limit block 54. The limit groove 53 and the limit block 54 are designed with a T-shaped structure to limit the movement of the triangular prism rod 55. The limit block 54 is located inside the limit groove 53. The position of the sub-rod 222 corresponding to the triangular prism rod 55 is designed with an inclined structure. One side of the triangular prism rod 55 contacts the baffle 43, one side contacts the inclined surface of the sub-rod 222, and one side contacts the end of the main rod 221.

[0045] The downward bending of the midpoint of the cleaning plate 20 can increase the friction force between the cleaning plate 20 and the gas distribution plate 10. The upper end surfaces of the cleaning plate 20 are all designed with an arc-shaped structure. The surfaces of the lower toothed plate 27 meshing with the first gear 30 are also designed with an arc-shaped structure, avoiding the accumulation of materials on the surfaces of the cleaning plate 20 and the lower toothed plate 27.

Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0047] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
