[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Refer to the instruction manual Figure 1-7 The utility model provides an external fluidized bed of a fluidized bed drying tower for cooling materials, comprising a bracket 1, a fluidized bed lower portion 2 is provided on the top of the bracket 1, the fluidized bed lower portion 2 is connected to the bracket 1 via a plurality of springs 3, a fluidized bed upper portion 4 is fixedly provided on the top of the fluidized bed lower portion 2, a perforated plate 5 is provided between the fluidized bed upper portion 4 and the fluidized bed lower portion 2, the perforated plate 5 is connected to the inner wall of the fluidized bed lower portion 2, and two motors 6 are fixedly provided at the bottom of one end of the fluidized bed lower portion 2;

[0028] The upper part 4 and the lower part 2 of the fluidized bed are both fixedly penetrated with a manhole 13 for inspection and maintenance. The staff can open the manhole 13 to inspect and clean the inside of the fluidized bed. The bottom side of the lower part 2 of the fluidized bed is connected to an air inlet pipe 14. The upper part 4 of the fluidized bed is fixedly penetrated with a plurality of cleaning balls 15 for connecting to a fan to transport gas to the inside of the fluidized bed.

[0029] During use, the material is conveyed between the upper fluidized bed 4 and the lower fluidized bed 2 through the feed port of the upper fluidized bed 4. At the same time, the air inlet pipe 14 is connected to the fan, and the fan is used to convey gas into the lower fluidized bed 2. The gas passes through the orifice plate 5 and evenly enters between the upper fluidized bed 4 and the lower fluidized bed 2, and flows upward at a certain speed. When the gas speed reaches the critical speed for suspending the material, the material between the upper fluidized bed 4 and the lower fluidized bed 2 begins to be fluidized, forming a state similar to that of a fluid.

[0030] In the fluidized state, the material moves violently under the action of the gas, showing a complex flow behavior. The material is constantly tumbling, colliding, and mixing. This movement makes the contact between the materials more frequent, which is conducive to heat transfer. In addition, depending on the size, density and other characteristics of the materials, the materials in the upper part 4 of the fluidized bed and the lower part 2 of the fluidized bed may be stratified to a certain extent. At the same time, due to the disturbance of the gas and the movement of the materials, the materials in different layers are also constantly mixed, thereby maintaining the uniformity of the entire fluidized bed.

[0031] In addition, heat transfer in the upper part 4 of the fluidized bed and the lower part 2 of the fluidized bed is mainly achieved through convection heat exchange between the material and the gas and heat conduction between the materials. Due to the movement of the material and good gas-solid contact, the heat transfer coefficient is high, which can achieve rapid heat transfer.

[0032] Refer to the instruction manual Figure 1-7 The upper portion 4 of the fluidized bed is fixed with a plurality of observation components 7, and the observation components 7 include two ring plates 701 fixedly passing through the upper portion 4 of the fluidized bed, and the outer walls of the two ring plates 701 are fixed with detachable ring plates 702, and the inner portion of the ring plates 702 is fixed with tempered glass 703;

[0033] Furthermore, a cleaning assembly 8 is provided on the tempered glass 703. The cleaning assembly 8 includes an arc-shaped plate 1 801 and an arc-shaped plate 2 802 distributed on the top and bottom of the tempered glass 703. Two embedded grooves 803 are provided on the sides of the arc-shaped plate 1 801 and the arc-shaped plate 2 802. Electromagnets 804 are fixedly provided inside the two embedded grooves 803 on the arc-shaped plate 1 801. Iron blocks 805 are fixedly provided inside the two embedded grooves 803 on the arc-shaped plate 2 802. The iron blocks 805 are magnetically attracted to the electromagnets 804 to facilitate adjustment of the position of the arc-shaped plate 2 802.

[0034] Furthermore, a mounting groove 806 is provided at the top of the second curved plate 802. A cleaning cloth 807 is fixed inside the mounting groove 806. The cleaning cloth 807 is placed between the two iron blocks 805. The cleaning cloth 807 is used to wipe the inner wall of the tempered glass 703 to prevent the material from contaminating the tempered glass 703.

[0035] The inner walls of the ring plate 1 701 and the ring plate 2 702 are both provided with an annular slide groove 9, and the outer walls of the arc plate 1 801 and the arc plate 2 802 are both fixed with a detachable arc slider 10, and the arc slider 10 is slidably set in the annular slide groove 9. The arc slider 10 cooperates with the annular slide groove 9 to improve the stability of the arc plate 1 801 and the arc plate 2 802. The top of the arc plate 1 801 is provided with a storage groove 11, and a shift rod 12 is fixed in the storage groove 11 to facilitate the staff to adjust the position of the arc plate 1 801 and the arc plate 2 802.

[0036] By setting two observation components 7 on the upper part 4 of the fluidized bed, the staff can observe the fluidization state of the material inside the fluidized bed through the tempered glass 703 to ensure the normal operation of the fluidized bed, and an arc plate 1 801 and an arc plate 2 802 are set on the tempered glass 703. The arc plate 1 801 and the arc plate 2 802 are magnetically attracted to each other through the electromagnet 804 and the iron block 805. When the staff grasps the lever 12 to move the arc plate 1 801, the arc plate 2 802 is also moved. The cleaning cloth 807 on the arc plate 2 802 can remove the material attached to the inner wall of the tempered glass 703 to prevent the material from obstructing the observation line of sight. When the fluidized bed is not in use, the ring plate 2 702, the arc plate 1 801 and the arc plate 2 802 are removed, and the cleaning cloth 807 is replaced.

[0037] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
