[0002] A fluidized bed dryer, also known as a boiling dryer, operates based on the principles of fluid dynamics. It allows hot air to pass through the material layer to be dried from the bottom of the device. When the air flow velocity reaches a certain value, the material particles will be in a suspended state similar to liquid boiling in the hot air flow, which greatly increases the contact area between the material and the hot air. The hot air transfers heat to the material, causing the moisture in the material to evaporate rapidly, thus achieving the purpose of drying; Among them, there is a large amount of waste heat in the air flow discharged from the fluidized bed dryer. However, due to the lack of effective waste heat recovery measures in traditional fluidized bed dryers, the waste heat in the air flow is difficult to be effectively utilized, resulting in relatively high overall energy consumption.

[0027] As Figures 1 to 8 shown, it shows an electric heating boiling dryer in an embodiment of the present invention. In some examples, it includes: An air supply box 1, the top end of the air supply box 1 is fixedly connected to a boiling dryer main body 2, and the air flow outlet of the boiling dryer main body 2 is fixedly connected to an exhaust pipe 3; A support frame 4, the support frame 4 is fixedly connected to one end of the air supply box 1, a waste heat recovery component 5 is assembled on the support frame 4, and the waste heat recovery component 5 is used to cooperate with the exhaust pipe 3 to recover the heat in the exported air flow; A transmission fan 6, the transmission fan 6 is fixedly connected to one end of the support frame 4, the output end of the transmission fan 6 is fixedly connected to an air supply pipe 7, an electric heating wire 8 is fixedly connected inside the air supply pipe 7 at the end far from the transmission fan 6, the input end of the transmission fan 6 is fixedly connected to a transmission pipe 9, and a filtering component 10 is assembled at the end of the transmission pipe 9 far from the transmission fan 6; An air distribution component 11, the air distribution component 11 is fixedly connected inside the air supply box 1 and is used to apply the air flow transmitted by the air supply pipe 7 at the boiling bed of the boiling dryer main body 2; In this embodiment, the boiling dryer main body 2 includes: A box body, made of corrosion-resistant materials such as stainless steel, which is the main place for material boiling drying; The fluidized bed is installed at the bottom of the box body and is provided with many evenly distributed small holes on it. Its function is to evenly distribute hot air across the entire cross-section of the bed layer, enabling the material to come into full contact with the hot air and achieve a good fluidized state; Cyclone separator: used to recover most of the fine powder materials carried away by the airflow during the drying process, improving the material recovery rate; Discharge device, located at one end of the box body, for discharging the dried material; Among them, the working principle of the main body 2 of the fluidized bed dryer is as follows: The wet material to be dried is added to the distribution plate inside the fluidized bed through the feeding device. Hot air evenly enters the bed layer through the small holes on the distribution plate. When the flow rate of the hot air reaches a certain value, the material particles begin to suspend in the airflow, forming a state similar to liquid boiling, that is, the fluidized state.

[0028] In the fluidized state, the material comes into full contact with the hot air, and the hot air transfers heat to the material, causing the moisture in the material to evaporate rapidly. At the same time, the material continuously tumbles and mixes within the bed layer, ensuring the uniformity of drying; The dried material and the waste gas carrying moisture rise together and enter the cyclone separator. In the cyclone separator, most of the larger particle materials are separated from the airflow under the action of centrifugal force and are finally collected through the discharge device; In summary, the main body 2 of the fluidized bed dryer is a mature existing technology and will not be elaborated here; For example, as Figure 4 shown, the waste heat recovery component 5 includes: Waste heat recovery tank 12, the waste heat recovery tank 12 is fixedly connected to the top end of one side of the support frame 4. Through holes 13 are provided at both ends of the waste heat recovery tank 12, and the air supply pipe 7 also passes through the two through holes 13; Gas guide pipe 14, the gas guide pipe 14 is fixedly connected inside the waste heat recovery tank 12. An intake pipe 15 and an outlet pipe 16 are respectively fixedly connected to both ends of the gas guide pipe 14. The end of the exhaust pipe 3 far from the main body 2 of the fluidized bed dryer is fixedly connected to the intake pipe 15, and a transfer pipe 17 is fixedly connected at the outlet pipe 16; For example, as Figure 4 shown, a liquid adding pipe is fixedly connected to the top end of the waste heat recovery tank 12, and a liquid discharge pipe is fixedly connected to the bottom of one end of the waste heat recovery tank 12. Through the setting of the liquid adding pipe, when the heat exchange liquid inside the waste heat recovery tank 12 is insufficient, the heat exchange liquid can be supplemented into the waste heat recovery tank 12 through the liquid adding pipe. And in this embodiment, a sealing plug is provided above the liquid adding pipe to block the liquid adding pipe when it is not in use, avoiding the leakage of heat from the waste heat recovery tank 12 through the liquid adding pipe. And through the setting of the liquid discharge pipe, when the heat exchange liquid inside the waste heat recovery tank 12 is turbid, it can be conveniently discharged from the waste heat recovery tank 12. At the same time, a manual valve is provided at the liquid discharge pipe for controlling the on / off of the liquid discharge pipe; More specifically, a feedback window is provided on one side of the waste heat recovery tank 12, and a transparent sealing plate is fixedly connected inside the feedback window. Through the setting of the feedback window, personnel can directly view the state of the heat exchange liquid inside the waste heat recovery tank 12 through the feedback window; For example, as Figure 4 shown, the air guide pipe 14 is spiral, and the material of the air guide pipe 14 is copper. Through the structural characteristics of the air guide pipe 14, after the air flow enters the inside of the air guide pipe 14, it can flow along its path, greatly increasing the heat exchange time of the air flow, making the waste heat recovery in the air flow more complete, and through the material characteristics of the air guide pipe 14, the heat in the air flow can be more fully exchanged with the liquid inside the waste heat recovery tank 12; For example, as Figure 5 shown, the filtering assembly 10 includes: A carrying cylinder 18, the carrying cylinder 18 is fixedly connected to the top of the support frame 4, the middle of the top of the carrying cylinder 18 is fixedly connected with an assembly pipe 19, and one end of the transfer pipe 17 far from the air outlet pipe 16 is fixedly connected with the assembly pipe 19. A limiting through groove 20 and a clamping groove 21 are provided on the outer side of the carrying cylinder 18, and the clamping groove 21 is located at the end of the limiting through groove 20. The clamping groove 21 has an opening, and the opening is communicated with the limiting through groove 20; A positioning cylinder 22, a clamping rod 23 is fixedly connected to the outer side of the positioning cylinder 22, and the clamping rod 23 is clamped and connected with the clamping groove 21. An avoidance hole 24 is provided in the middle of the top of the positioning cylinder 22. A filter screen 25 is fixedly connected to one end inside the positioning cylinder 22, and a plurality of adsorption plates 26 are fixedly connected to the other end inside the positioning cylinder 22; For example, as Figure 5 shown, a rubber sleeve is fixedly connected to the outer side of the clamping rod 23, and the width of the opening of the clamping groove 21 is smaller than the diameter of the clamping rod 23. Through the setting of the rubber sleeve, the wear resistance of the clamping rod 23 can be improved, and the loss of the clamping rod 23 during displacement inside the limiting through groove 20 can be reduced. And through the change of the opening of the clamping groove 21 and the diameter of the clamping rod 23, when the clamping rod 23 rotates towards the opening of the clamping groove 21, the clamping rod 23 will directly contact the opening. As the clamping rod 23 continues to rotate, the clamping rod 23 will squeeze the opening and expand the opening until the opening can be passed by the clamping rod 23. When the clamping rod 23 reaches the inside of the clamping groove 21, due to the loss of extrusion of the opening, the clamping rod 23 can be clamped inside the clamping groove 21 through the restoration of the opening. In order to make the opening of the clamping groove 21 deform, in this embodiment, the carrying cylinder 18 is made of a deformable material; More specifically, the material of the adsorption plate 26 is activated carbon; As Figures 5 to 8 shown, it shows the air distribution assembly 11 in another embodiment of the present invention.

[0029] In some examples, the air distribution assembly 11 includes: The main air distribution pipe 27 is fixedly connected inside the air supply box 1. One end of the air supply pipe 7 far from the transmission fan 6 is communicated with the main air distribution pipe 27. A plurality of transmission branch pipes 28 are fixedly connected to the top end of the main air distribution pipe 27. A positioning seat 29 is fixedly connected to the outer side of the transmission branch pipe 28. A cloth air pipe 30 is fixedly connected to the top end of the positioning seat 29. The top end of the transmission branch pipe 28 is communicated with the cloth air pipe 30. A flow dividing pipe 31 is fixedly connected to the middle of one side of the cloth air pipe 30. A cloth air branch pipe 32 is rotatably connected to one end of the flow dividing pipe 31 far from the cloth air pipe 30. One end of each positioning seat 29 is fixedly connected with an extension seat 33; The support shaft rod 34 is rotatably connected to one end of the extension seat 33. One end of the support shaft rod 34 is fixedly connected with a linkage plate A 35. A linkage through groove A 36 is formed in the middle of the linkage plate A 35. An eccentric plate 37 is fixedly connected to the outer side of the cloth air branch pipe 32. One end of the eccentric plate 37 far from the cloth air branch pipe 32 is also movably connected inside the linkage through groove A 36; The linkage plate B 38 is fixedly connected to one end of the linkage plate A 35 close to the support shaft rod 34. A linkage through groove B 39 is formed in the middle of the linkage plate B 38. A linkage rod 40 is movably connected between a plurality of the linkage through grooves B 39; The mounting seat 41 is fixedly connected to one end of the top of the main air distribution pipe 27. A driving motor 42 is fixedly connected to the top end of the mounting seat 41. The output end of the driving motor 42 is fixedly connected with a driving spur gear 43. A reduction spur gear 44 is fixedly connected to the outer side of the cloth air branch pipe 32 corresponding to the driving spur gear 43. The reduction spur gear 44 is meshed and connected with the driving spur gear 43; For example, as Figure 7 shown, a rotary joint is arranged between the cloth air branch pipe 32 and the flow dividing pipe 31. The cloth air branch pipe 32 and the flow dividing pipe 31 are connected through the rotary joint. Through the arrangement of the rotary joint, while not affecting the airflow inside the cloth air pipe 30 from entering the cloth air branch pipe 32, it also enables the cloth air branch pipe 32 to smoothly rotate under the support of the flow dividing pipe 31, reducing the interference during the rotation of the cloth air branch pipe 32; For example, as Figure 8 shown, one end of the eccentric plate 37 far from the cloth air branch pipe 32 is fixedly connected with a transmission rod. The eccentric plate 37 is movably connected inside the linkage through groove A 36 through the transmission rod. Through the arrangement of the transmission rod, during the rotation of the eccentric plate 37, the linkage plate A 35 can be pressed by means of the adaptive movement of the transmission rod inside the linkage through groove A 36, prompting the linkage plate A 35 to rotate under the support of the support shaft rod 34; For example, as Figure 8As shown, one end of each positioning seat 29 is fixedly connected to a linear guide rod, and the linkage rod 40 is also slidably connected to the outside of the linear guide rod. Through the setting of the linear guide rod, the displacement of the linkage rod 40 can be limited to avoid uncontrollable displacement of the linkage rod 40, and one end of each linear guide rod is fixedly connected to a limiting plate. Through the setting of the limiting plate, the linkage rod 40 can be prevented from detaching from the linear guide rod, thereby ensuring the stability of the linkage rod 40 during application.

[0030] Working principle: First, the material is introduced into the boiling dryer body 2, and the transmission fan 6 and the electric heating wire 8 are started. Through the operation of the transmission fan 6, the airflow at the carrying cylinder 18 can be sent to the air distribution main pipe 27 through the transmission pipe 9 and the air supply pipe 7. Before the airflow enters the transmission pipe 9, the airflow will pass through the filter 25 and the adsorption plate 26 in sequence to filter impurities and particles in the airflow with the help of the filter 25 and the adsorption plate 26. When the airflow is transmitted inside the air supply pipe 7, the heat generated by the operation of the electric heating wire 8 can heat the airflow and finally reach the inside of the air distribution main pipe 27; The airflow reaching the interior of the air distribution main pipe 27 will be divided into multiple air distribution pipes 30 and air distribution branch pipes 32 through the transmission branch pipe 28, so that the high-temperature airflow will be sprayed onto the distribution plate in the boiling bed of the boiling dryer body 2 through the air distribution pipes 30 and the air distribution branch pipes 32, blowing the material up and boiling it to dry it. The transmission motor 42 can be started to cause the transmission spur gear 43 to shift the reduction spur gear 44, thereby driving the air distribution branch pipe 32 connected to the reduction spur gear 44 to rotate, and by rotating the eccentric plate 37 at the air distribution branch pipe 32, the eccentric plate 37 is adaptively displaced in the linkage groove A36, pressing the linkage plate A35. The linkage plate A35 rotates with the support of the support shaft 34, and the linkage plate B38 is connected to the linkage plate A35, so that the linkage plate B38 can rotate synchronously with the linkage plate A35 to promote the linear displacement of the linkage rod 40. Since the linkage rod 40 is connected between multiple linkage slots B39, when the linkage rod 40 moves, it can synchronously push the remaining linkage plates B38, prompting the remaining linkage plates A35 to press the remaining eccentric plates 37, prompting the multiple air distribution branch pipes 32 to rotate synchronously, and finally changing the airflow derivation direction of the air distribution branch pipes 32, thereby reducing dead corners and agglomeration of materials, so that the materials can be fully dried. The air flow entering the interior of the main body 2 of the flash dryer will ultimately be injected into the interior of the intake pipe 15 through the exhaust pipe 3 and flow along the guide pipe 14. Since the guide pipe 14 is located inside the waste heat recovery tank 12, the temperature in the air flow will exchange heat with the liquid inside the waste heat recovery tank 12 through the guide pipe 14, thereby recovering the waste heat in the air flow. Subsequently, when the air flow inside the air supply pipe 7 passes through the waste heat recovery tank 12, it can preheat the air flow by means of the liquid heated at the waste heat recovery tank 12. When the gas flows out of the guide pipe 14, it will be injected into the interior of the positioning cylinder 22 through the transfer pipe 17 and the assembly pipe 19 to filter the particles in the air flow through the adsorption plate 26; When the application effects of the filter net 25 and the adsorption plate 26 are not good, first push the latch 23 to rotate towards the opening direction of the clamping groove 21, so that the latch 23 squeezes the opening of the clamping groove 21 until the opening of the clamping groove 21 can be passed by the latch 23. When the latch 23 reaches inside the limit through groove 20, pull the latch 23 to slide the positioning cylinder 22 along the limit through groove 20 to extract the positioning cylinder 22 from the carrier cylinder 18 for replacement.
