Description

Technical Field

[0001] The invention relates to the technical field of chemical drying equipment, in particular to an internal heating type drying fluidized bed. Background Art

[0002] Fluidized bed drying technology is one of the most widely used drying methods in industry. It uses airflow to suspend solid particles, creating a fluidized state and achieving efficient heat and mass transfer. In recent years, with the increasing demands for drying efficiency and energy consumption in industries such as chemical, pharmaceutical, and food, traditional fluidized beds have faced challenges in terms of thermal efficiency and temperature uniformity.

[0003] The bed surface of a traditional drying fluidized bed is generally provided with holes for air circulation. When materials are placed on the bed surface, the airflow through the holes can blow the materials upward, thereby making the materials float and increasing the drying effect. However, in actual use, there is a certain distance between the holes on the bed surface, and the bed surface is usually fixedly installed inside the cavity. This makes it difficult for the materials placed between the holes to come into contact with the airflow, and thus difficult to blow them up, which in turn affects the drying effect of the materials.

[0016] Working principle: The material is introduced into the feed chamber through the feed port, and the second motor is turned on at the same time. The second motor drives the driving gear to rotate, and the driving gear drives the driven gear to rotate, thereby driving the first crushing roller and the second crushing roller to rotate relative to each other, thereby crushing the material entering the feed chamber. The crushed material can fall onto the surface of the screen plate, and the vibration motor is turned on. The vibration motor drives the screen plate to vibrate, thereby screening the material, and the screened material enters the interior of the guide port; When the driven gear rotates, it can drive the first worm to rotate through the transmission of the connecting belt, the first worm drives the first worm wheel to rotate, the first worm wheel drives the auger to rotate, and the auger can transport the material in the guide port to the inside of the drying chamber. The material entering the drying chamber can be placed on the top of the bed surface; Turn on the hot air blower, which blows hot air into the drying chamber through the pipe group, and then blows the material upwards through the holes on the bed surface. The hot air flow blowing the material can make the material float inside the drying chamber. Simultaneously turn on the microwave heating tube to circulate and heat the floating material, thereby enhancing the drying efficiency of the material. When the first motor is turned on, the first motor drives the third worm to rotate, and the third worm drives the second worm on both sides to rotate through the third worm gear. The second worm drives the telescopic rod to rotate through the second worm gear, and the telescopic rod drives the transmission rod to rotate. The transmission rod drives the undulating rod to rotate around the slot on the surface of the undulating seat, thereby driving the transmission rod to extend and retract at the center of the undulating seat, and the transmission rod pushes and pulls the bed surface to move back and forth, thereby driving the bed surface to screen the material on its top, thereby increasing the probability of the material on the top of the bed surface overlapping with the holes, thereby enhancing the effect of blowing the material, and indirectly enhancing the efficiency of drying the material. When the third worm rotates, it can drive the second bevel gear to rotate, and the second bevel gear drives the first bevel gear to rotate, and the first bevel gear drives the rotating rod to rotate, and the rotating rod drives the striking rod to rotate. The striking rod contacts with the material, which can break up the condensed material, thereby further increasing the effect of contact between the material and the heat medium, thereby enhancing the efficiency of drying it. After the material is dried, the second suction machine can be turned on to absorb the dried material on the bed surface and then discharge it, thereby completing the discharging operation.

[0017] The present invention provides an internally heated drying fluidized bed having the following beneficial effects: 1. The present invention is provided with a screening assembly. When in use, the telescopic rod is rotated, the telescopic rod drives the transmission rod to rotate, and the transmission rod drives the undulating rod to rotate on the wavy groove on the surface of the undulating seat, thereby driving the transmission rod to extend and retract back and forth in the undulating seat. When the transmission rod is extended and retracted, the bed surface can be pushed and pulled back and forth inside the drying chamber, thereby screening the material on the bed surface, increasing the contact probability between the material and the holes, and facilitating the blowing of the material by the airflow in the holes, thereby enhancing the drying effect of the material.

[0018] 2. In the present invention, a rotating rod and a striking rod are arranged inside the drying chamber. When the airflow blows up the material, the rotating rod can drive the striking rod to rotate through the rotation of the rotating rod. The striking rod can hit the blown material, thereby breaking up the condensed particulate material, increasing the contact effect between the material and the heat medium, and enhancing the efficiency of material drying.

[0019] 3. In the present invention, a feed chamber is provided at the top of the drying chamber, and a first crushing roller and a second crushing roller are provided inside the feed chamber. Through the relative rotation of the first crushing roller and the second crushing roller, materials with larger particle sizes can be crushed, thereby pre-treating the materials before drying, thereby enhancing the functionality of the equipment.

[0020] 4. The present invention sets a sieve plate inside the feed chamber and installs a vibration motor at the bottom of the sieve plate. The sieve plate can be vibrated by the vibration motor, and the crushed material can be screened. By setting a first suction machine and turning on the first suction machine, the incompletely crushed material can be adsorbed into the feed pipe, and then transferred to the feed port by the feed pipe, and then it can be subjected to secondary circulation crushing, thereby increasing the uniformity of the material particles and enhancing the quality of subsequent drying and discharge.

[0021] 5. The present invention is provided with a linkage component, which can drive the auger to rotate while crushing the material.

[0024] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] Please see the attached Figure 1 , Attachment Figure 3 and attached Figure 8The embodiment of the present invention provides an internal heating drying fluidized bed, comprising a drying chamber 1, wherein a bed surface 17 is movably installed inside the drying chamber 1, an arc-shaped cover 4 is installed on the top of the drying chamber 1, a microwave heating tube 52 is installed inside the arc-shaped cover 4, a connecting pipe 5 is connected to the top surface of the arc-shaped cover 4, one end of the connecting pipe 5 is connected to a collecting device 6, the bottom of the drying chamber 1 is connected to a pipe group 3, one end of the pipe group 3 is connected to a hot air blower 2, the top surface of the drying chamber 1 is connected to a feeding chamber 7, and the feeding chamber 7 and the drying chamber 1 are connected through a material guide port 22, an auger 31 is provided inside the material guide port 22, a first crushing roller 20 and a second crushing roller 21 are sequentially provided inside the drying chamber 1, one end of the auger 31 is connected to a linkage assembly, a sieve plate 19 is provided inside the feeding chamber 7, a rotating rod 14 is provided inside the drying chamber 1, a plurality of striking rods 15 are fixedly connected to the outer surface of the rotating rod 14, a cavity 23 is opened inside the drying chamber 1, and a screening assembly is installed inside the cavity 23.

[0026] Specifically, the equipment can be combined into the basic functions of the drying fluidized bed equipment body through the coordinated functions among the drying chamber 1, the arc-shaped cover 4, the pipe group 3, the hot air blower 2, the connecting pipe 5 and the collecting device 6. When in use, the granular material can be introduced into the interior of the drying chamber 1. At this time, the material will be placed on the top surface of the bed surface 17. When the hot air blower 2 is turned on, the hot air blower 2 can blow the hot air into the interior of the pipe group 3. The pipe group 3 is connected to the bottom of the drying chamber 1, and the hot air can be blown upward. The hot air passes through the holes on the surface of the bed surface 17 and continues to blow upward, thereby blowing the material on the bed surface 17. Through the action of the hot air flow, the material can be moved on the bed surface 17. The capture forms a fluid-like motion state, thereby increasing the contact area between the material and the heat medium, thereby enhancing the efficiency of drying the material. When water vapor is generated when drying the material, the water vapor can enter the interior of the collecting device 6 through the arc cover 4, and then the water vapor can be collected and processed. The basic operating process of this equipment is similar to that of a traditional drying fluidized bed, so the structure and model of the main components are not described in detail here. A microwave heating tube 52 is provided inside the arc cover 4. When the material floats and the heat is released, the microwave heating tube 52 can be turned on to achieve composite multi-stage heating of hot air and microwaves, thereby further enhancing the efficiency of drying the material.

[0027] Please see the attached Figure 5 The screening assembly includes a telescopic rod 39, an ups and downs seat 50, a transmission rod 40 and an ups and downs rod 51. The two transmission rods 40 are rotatably mounted on one side of the bed surface 17 through bearings. The telescopic rod 39 is fixedly mounted on one end of the transmission rod 40. The ups and downs rod 51 is fixedly mounted on both sides of the transmission rod 40. The ups and downs seat 50 is arranged inside the cavity 23, and a wavy notch is opened on one side of the ups and downs seat 50, and the ups and downs rod 51 extends into the inner side of the notch.

[0028] Specifically, a wave-shaped notch is provided on the surface of the undulating seat 50, one end of the undulating rod 51 extends into the wave-shaped slide 47, and the undulating rod 51 is slidably connected to the surface of the undulating seat 50. Therefore, when the telescopic rod 39 drives the transmission rod 40 to rotate, the transmission rod 40 can drive the undulating rod 51 to rotate along the wave-shaped notch provided on the surface of the undulating seat 50, thereby driving the undulating rod 51 to rotate in a wave-shaped manner. The transmission rod 40 is movably installed at the center of the undulating seat 50. Therefore, when the undulating rod 51 rotates, it can drive the transmission rod 40 to extend and retract back and forth at the center of the undulating seat 50. Since one end of the transmission rod 40 is rotatably connected to one side of the bed surface 17 through a bearing, and the shaft The bearing is fixed on one side of the bed surface 17, so when the transmission rod 40 rotates, it can rotate on one side of the bed surface 17 through the bearing. When the undulating rod 51 is extended and retracted, the bed surface 17 can be pulled back and forth to move back and forth inside the drying chamber 1. When the bed surface 17 moves back and forth, the material on the top can be screened. The material on the top changes its position on the bed surface 17 after screening, thereby preventing the material from being stationary on the bed surface 17, causing the airflow to not contact the material between the holes on the surface of the bed surface 17. Screening the material back and forth can increase the probability of the material and the holes overlapping, thereby facilitating the airflow through the holes to blow the material upward, thereby enhancing the effect of drying the material.

[0029] Please see the attached Figure 5 and attached Figure 6 Two fixed plates 38 are fixedly installed inside the cavity 23, and the undulating seat 50 is fixedly installed on the inner side of the fixed plate 38. A sliding groove 47 is opened on the inner wall of the telescopic rod 39, and a slider 48 is slidably installed inside the sliding groove 47. A second spring 49 is installed inside the telescopic rod 39.

[0030] Specifically, the ups and downs seat 50 is fixedly mounted on one side of the fixed plate 38, thereby ensuring the stability of the ups and downs seat 50. The telescopic rod 39 is divided into an inner rod and an outer rod, and the two ends of the second spring 49 are connected to the inner rod and the outer rod respectively. Therefore, when the telescopic rod 39 drives the transmission rod 40 to rotate and drives the ups and downs rod 51 to rotate along the wavy notch on the surface of the ups and downs seat 50, the transmission rod 40 is extended and retracted to drive the telescopic rod 39 to extend and retract. When the telescopic rod 39 is extended and retracted, the inner rod of the telescopic rod 39 can squeeze the second spring 49 inward, and at the same time, the second spring 49 is elastically engaged. The potential energy can push the inner rod to move outward, thereby the transmission rod 40 applies a reset force, ensuring the normal screening movement of the bed surface 17, and the inner wall of the outer rod of the telescopic rod 39 is provided with a slide groove 47, and the sliders 48 are fixedly arranged on both sides of the inner rod of the telescopic rod 39. Therefore, when the telescopic rod 39 is extended or retracted, the slider 48 can slide inside the slide groove 47, thereby increasing the stability and directionality of the extension and retraction of the telescopic rod 39. At the same time, the slide groove 47 can limit the slider 48, and when the outer rod of the telescopic rod 39 rotates, the inner rod of the telescopic rod 39 can be driven to rotate synchronously.

[0031] Please see the attached Figure 4One end of the two telescopic rods 39 is fixedly connected to the second worm gear 41, the top of the two second worm gears 41 is meshed with the second worm 42, a third worm gear 43 is fixedly connected between the two second worm gears 42, one side of the third worm gear 43 is meshed with the third worm 44, the top of the third worm gear 44 is fixedly connected to the second bevel gear 46, one side of the second bevel gear 46 is meshed with the first bevel gear 45, and one end of the rotating rod 14 is fixedly mounted on one side of the first bevel gear 45.

[0032] Specifically, when the third worm gear 43 rotates, it can drive the second bevel gear 46 at the top to rotate, and the second bevel gear 46 can drive the first bevel gear 45 to rotate. The first bevel gear 45 can drive the rotating rod 14 to rotate, and the rotating rod 14 can drive the striking rod 15 to rotate inside the drying chamber 1. The striking rod 15 rotates to strike the floating material, and then break up the condensed material. The broken material can increase its contact area with the heat medium, thereby enhancing the drying efficiency. At the same time, when the third worm 44 rotates, it can drive the third worm gear 43 to rotate, and the third worm gear 43 drives the second worm gears 42 on both sides to rotate, and the second worm gear 42 drives the second worm gear 41 to rotate, and the second worm gear 41 drives the two telescopic rods 39 to rotate, thereby screening the bed surface 17, thereby enhancing the linkage of the equipment when used, and the linkage effect is tight, thereby enhancing the functionality.

[0033] Please see the attached Figure 2 A drive seat 12 is fixedly installed on one side of the drying chamber 1, and a first motor 13 is fixedly installed on the outer surface of the drying chamber 1 through a fixing frame, and the output end of the first motor 13 extends into the interior of the drive seat 12 and is connected to the third worm 44.

[0034] Specifically, the third worm 44 can be driven to rotate by the first motor 13, and the second bevel gear 46, the second worm 42 and the second worm wheel 41 are all rotatably mounted inside the driving seat 12 via the rotating shaft, thereby ensuring the stability of the transmission.

[0035] Please see the attached Figure 8 The linkage assembly includes a driving gear 26, a driven gear 27, a connecting belt 28, a first worm 30 and a first worm wheel 29. The first worm wheel 29 is fixedly mounted on one end of the auger 31. The first worm 30 is arranged on the top of the first worm wheel 29, and the first worm wheel 29 is meshed with the first worm 30. The driving gear 26 and the driven gear 27 are respectively fixedly mounted on one side of the first crushing roller 20 and the second crushing roller 21. The ends of the connecting belt 28 are respectively connected to the first worm 30 and the driven gear 27 through pulleys.

[0036] Specifically, when the driving gear 26 rotates, the driven gear 27 can be driven to rotate. The synchronous rotation of the driving gear 26 and the driven gear 27 can drive the first crushing roller and the second crushing roller 21 to rotate relative to each other, so that the material to be dried can be crushed. When the material is crushed to a specified particle size, it can be blown up by the air flow to prevent the material from settling due to excessive particle size, which leads to uneven drying. When the driven gear 27 rotates, the first worm 30 can be driven to rotate through the transmission of the connecting belt 28. The first worm 30 can drive the first worm wheel 29 to rotate, and the first worm wheel 29 can drive the auger 31 to rotate. The auger 31 is installed inside the material guide port 22. When the auger 31 rotates, the material entering the material guide port 22 can be transported to the inside of the drying chamber 1, so as to prevent the material from accumulating inside the material guide port 22 and clogging the material guide port 22, while further enhancing the linkage performance of the equipment when in use.

[0037] Please see the attached Figure 3 and attached Figure 8 A second motor 32 is fixedly mounted on the outer surface of the feed cavity 7 through a fixing frame, and the output end of the second motor 32 is connected to the driving gear 26 , and a guide plate 18 is symmetrically mounted inside the feed cavity 7 .

[0038] Specifically, the driving gear 26 can be driven to rotate by the second motor 32. The surfaces of the two guide plates 18 have a slope, and a gap is left between the two guide plates 18. The guide port 22 is placed below the gap. Therefore, after the material is crushed, the material can enter the interior of the guide port 22 through the guidance of the guide plates 18, which facilitates the transportation of the material.

[0039] Please see the attached Figure 2 , Attachment Figure 3 and attached Figure 9 A discharge port 16 is provided on one side of the drying chamber 1. A second suction machine 11 is fixedly installed on the outer surface of the drying chamber 1 through a fixed frame, and the second suction machine 11 is communicated with the end of the discharge port 16. An electric push rod 33 is installed inside the drying chamber 1, and the telescopic end of the electric push rod 33 is connected to a sealing plate 35, and the sealing plate 35 extends into the interior of the discharge port 16. A guide rod 34 is symmetrically installed inside the sealing plate 35, and the bottom end of the guide rod 34 is connected to the sealing plate 35.

[0040] Specifically, the suction machine used in this device is a vacuum suction machine, which is equipped with a vacuum pump inside. Turning on the internal vacuum pump can create a negative pressure environment inside the suction machine, thereby adsorbing the material and transmitting it through the pipeline. It is widely used in various fields, so its specific structure and principle are not described in detail here. The suction port of the second suction machine 11 is opposite to the discharge port 16. Therefore, when the second suction machine 11 is turned on, the material placed on the bed surface 17 can be adsorbed, and the material adsorbed in the second suction machine 11 can be transported to the external environment, thereby completing the discharge work of this equipment. When drying the material, the electric push rod 33 can be turned on, and the electric push rod 33 can push the sealing plate 35 to move inside the discharge port 16. By moving the sealing plate 35, the discharge port 16 can be blocked, thereby preventing the material from entering the inside of the discharge port 16 during the drying operation, and the guide rod 34 is retractable. Therefore, when the sealing plate 35 moves, it can drive the guide rod 34 to retract and retract accordingly, thereby increasing the stability and directionality of the sealing plate 35 when moving.

[0041] Please see the attached Figure 4 and attached Figure 9 The inner wall of the drying chamber 1 is symmetrically provided with guide blocks 36 , and guide grooves 37 are opened on both sides of the bed surface 17 .

[0042] Specifically, the guide block 36 is placed inside the guide groove 37, and the guide block 36 is slidably connected to the guide groove 37. Therefore, when the bed surface 17 is sifted left and right, the guide block 36 can slide inside the guide groove 37, thereby increasing the stability and directionality of the bed surface 17 when sifting.

[0043] Please see the attached Figure 1 and attached Figure 7 A feed port 8 is provided at the top of the feed chamber 7, a vibration motor 24 is symmetrically installed at the bottom of the sieve plate 19, and a first spring 25 is fixedly connected to the four corners of the bottom surface of the sieve plate 19. A first suction machine 9 is fixedly installed on the outer surface of the feed chamber 7 through a fixed frame, and a feed pipe 10 is connected to the top of the first suction machine 9, and one end of the feed pipe 10 extends into the interior of the feed port 8.

[0044] Specifically, materials can be added to the inside of the feed chamber 7 through the feed port 8. After the crushing roller crushes the materials, the materials can fall to the top of the screen plate 19. At this time, the vibration motor 24 can be turned on. The vibration motor 24 can drive the screen plate 19 to vibrate. The vibration of the screen plate 19 can increase the screening effect of the materials on its top. The screened materials can fall to the inside of the guide port 22, and the incompletely crushed materials can remain on the top of the screen plate 19. At this time, the first suction machine 9 can be turned on. The first suction machine 9 can absorb the materials remaining on the screen plate 19 to the inside of the feed pipe 10, and then transfer them to the inside of the feed port 8 through the feed pipe 10, so that the materials can be recycled and crushed for the second time, thereby enhancing the functionality of this equipment when in use.

[0045] An internal heating drying fluidized bed in this embodiment can be placed in a designated position when in use, and the material can be introduced into the interior of the feed chamber 7 through the feed port 8. At the same time, the second motor 32 is turned on, and the second motor 32 drives the driving gear 26 to rotate, and the driving gear 26 drives the driven gear 27 to rotate, thereby driving the first crushing roller and the second crushing roller to rotate relative to each other, thereby crushing the material entering the feed chamber 7, and the crushed material can fall onto the surface of the screen plate 19, and the vibration motor 24 is turned on, and the vibration motor 24 drives the screen plate 19 to vibrate, thereby screening the material, and the screened material enters the interior of the guide port 22. The material remaining on the screen plate 19 can be sucked into the interior of the feed port 8 by the first suction machine 9, and subjected to secondary crushing; When the driven gear 27 rotates, it can drive the first worm 30 to rotate through the transmission of the connecting belt 28, the first worm 30 drives the first worm wheel 29 to rotate, and the first worm wheel 29 drives the auger 31 to rotate. The auger 31 can transport the material in the material guide port 22 to the interior of the drying chamber 1.
