Technical Field

[0001] This utility model relates to the field of fluidized bed dryer technology, and more specifically, to a feeding device for a high-efficiency fluidized bed dryer. Background Technology

[0002] A high-efficiency fluidized bed dryer is a tool that uses heated and purified air to form a fluidized state through stirring and negative pressure, thereby rapidly drying materials. It can be used for drying work in multiple industries such as pharmaceuticals and food. When using a high-efficiency fluidized bed dryer, raw materials need to be added to the machine, which requires the use of a feeding device.

[0003] When feeding materials that are prone to caking, if the materials are not properly treated, the caking material will be directly added to the dryer. At this time, the feeding speed will be too fast, exceeding the conveying capacity of the feeding device, which can easily cause blockage. In addition, adding caking material to the dryer will affect the drying effect of the material. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0026] Please see Figures 1-4 In this utility model: a feeding device for a high-efficiency fluidized bed dryer includes a cylinder 1, a feeding pipe 2 connected to the top of the cylinder 1, a feeding pipe 3 connected to the feed inlet of the high-efficiency fluidized bed dryer connected to the bottom of the cylinder 1, a screen plate 4 installed on the inner wall of the cylinder 1, a motor 5 fixedly connected to the bottom of the cylinder 1, a square rod 6 fixedly connected to the output shaft of the motor 5, the top end of the square rod 6 penetrating and extending into the interior of the cylinder 1, a sliding sleeve 7 slidably connected to the square rod 6, the inner wall of the sliding sleeve 7 being square, the outer side of the sliding sleeve 7 being rotatably connected to the screen plate 4, four crushing rods 8 fixedly connected to the outer side of the sliding sleeve 7, and an electric push rod 9 fixedly connected to the top of the cylinder 1, the telescopic end of the electric push rod 9 being rotatably connected to the sliding sleeve 7.

[0027] In this invention, when drying materials, the material is first added into the cylinder 1 through the feed pipe 2. The material falls onto the top of the sieve plate 4, which then sieves the material. Materials that meet the size requirements pass through the sieve plate 4 and enter the high-efficiency fluidized bed dryer through the feed pipe 3. Unqualified materials fall onto the top of the sieve plate 4. At this point, the user starts the motor 5, which drives the square rod 6 to rotate. The square rod 6 then drives the sliding sleeve 7 to rotate. During the rotation of the sliding sleeve 7, the crushing rod 8 rotates. The crushing rod 8 crushes materials with large clumps until they are broken down to the acceptable size. Small pieces of material are fed into the high-efficiency fluidized bed dryer for drying. The crushed material is of a suitable size, thus preventing clumping of the feed pipe 3 and avoiding the direct entry of large pieces of material into the high-efficiency fluidized bed dryer. This improves the drying effect and efficiency of the high-efficiency fluidized bed dryer. During the crushing process, the user can raise and lower the sliding sleeve 7 by activating the electric push rod 9. The raising and lowering of the sliding sleeve 7 changes the height of the crushing rod 8, which can crush materials of different heights, improving the crushing efficiency and thus enhancing the drying efficiency of the high-efficiency fluidized bed dryer.

[0028] Please see Figures 1-3The cylinder 1 has a cavity 10, which is annular in shape. The inner wall of the cavity 10 is connected to two conduits 11. The opposite ends of the two conduits 11 are respectively connected to the exhaust pipe of the high-efficiency boiling dryer and the air treatment device.

[0029] In this invention, the high-efficiency fluidized bed dryer generates a certain amount of waste gas during the drying process. The waste gas is introduced into the cavity 10 through the conduit 11, and the residual heat in the waste gas can be used to heat the cavity 10, thereby heating the cylinder 1. The heated cylinder 1 can preheat the material, further improving the drying efficiency of the high-efficiency fluidized bed dryer, and reducing the occurrence of material agglomeration, thus improving the practicality of the device.

[0030] Please see Figure 3 Among them, two crossbars 12 are fixedly connected to the sliding sleeve 7, and scrapers 13 are fixedly connected to the opposite ends of the two crossbars 12. The outer sides of the two scrapers 13 are in contact with the inner wall of the cylinder 1.

[0031] In this invention, the cooperation between the crossbar 12 and the scraper 13 can clean the inner wall of the cylinder 1 during the rotation of the sliding sleeve 7. The scraper 13 will scrape off the material adhering to the inner wall of the cylinder 1, thereby improving the practicality of the device.

[0032] Please see Figure 3 and 4 The screen plate 4 has two sliders 14 fixedly connected to its outer side. The inner wall of the cylinder 1 has two sliding grooves 15 that are slidably connected to the sliders 14. The top of each slider 14 is fixedly connected to a spring 16. The other end of each spring 16 is fixedly connected to the inner wall of the two sliding grooves 15. The sliding sleeve 7 has two connecting rods 17 fixedly connected to its top. The top of each connecting rod 17 is fixedly connected to a sliding rod 18. The bottom of the screen plate 4 has two trapezoidal blocks 19 fixedly connected to its bottom.

[0033] In this invention, after the material is crushed, the sliding sleeve 7 is raised to its highest point. At this time, the sliding rod 18 on the connecting rod 17 will contact the bottom of the screen plate 4. The rotation of the sliding sleeve 7 will drive the sliding rod 18 to slide along the bottom of the screen plate 4. During the sliding process, the sliding rod 18 will continuously slide past the bottom of the trapezoidal block 19. Whenever the sliding rod 18 slides past the bottom of the trapezoidal block 19, the screen plate 4 will rise and the spring 16 will be compressed until the sliding rod 18 slides past the trapezoidal block 19. At this time, the elastic force of the spring 16 is released, and the screen plate 4 will descend. As the sliding rod 18 continuously slides past the bottom of the trapezoidal block 19, the screen plate 4 will move up and down repeatedly, which can drive the material to tumble, thereby improving the efficiency of material screening and further improving the drying efficiency of the high-efficiency fluidized bed dryer.

[0034] Please see Figure 3The top of the slide bar 18 is provided with an installation groove, and the inner wall of the installation groove is rotatably connected to a roller 20.

[0035] In this invention, the roller 20 can reduce friction, improve the smoothness of device operation, reduce wear, and extend the service life of the device.

[0036] Please see Figure 3 The inner bottom wall of the cylinder 1 is inclined toward the feeding pipe 3.

[0037] In this invention, the bottom wall of the inner wall of the cylinder 1 is inclined towards the feeding pipe 3, which facilitates the rapid entry of materials from the feeding pipe 3 into the dryer, thereby improving the practicality of the device.

[0038] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
