[0002] Kaolin (mainly composed of aluminosilicate) usually contains high moisture (20% - 40%) after mining, and has fine particles and high viscosity. Therefore, a flash drying device is required to quickly dehydrate and dry the soil material.

[0003] The prior art (Chinese patent with publication number: CN210197868U, publication date: March 27, 2020) discloses a new type of special rotary flash dryer for kaolin, including a drying outer shell, a guiding feeding frame structure, a drying box, a feeding hopper, a guiding material frame, a feeding hopper, a heating and blowing frame structure, a shock-absorbing and reinforcing base structure, a driving motor, an opening, a rotating pipe, a spiral feeding blade, a discharging frame and a storage hopper. The guiding feeding frame structure is installed on the upper part of the drying outer shell; the feeding hopper is inserted into the upper part of the drying box; the guiding material frame is inserted into the upper left part of the drying outer shell; the feeding hopper is inserted into the upper left part of the guiding material frame. The setting of the positioning rod and the buffer spring on the transverse bottom plate of the present utility model is beneficial to buffering and shock-absorbing the bottom of the dryer during use; the annular heating pipe specifically uses a copper electric heating pipe, and two annular heating pipes are provided, which is beneficial to heating the gas blown out by the blower during use.

The top and bottom of the fixed column are movably connected to the inner wall of the main body of the machine through bearings; by setting the fixed box in the present utility model, it plays a role in protecting the internal components. By setting the main body of the machine, it is used to provide a drying space for the material. By setting the fixed column, it plays a role in fixing the stirring blade, the fixed sleeve and the fixing plate. By setting the turning plate, it is used to lift the material piled up at the bottom of the main body of the machine, thereby preventing the material from piling up at the bottom of the main body of the machine, and solving the problem that when the air draft of the dryer is small, larger particle size materials will deposit at the bottom of the main body of the machine, causing the stirring current of the main body of the dryer to overload and stop. After the deposited materials at the bottom of the dryer need to be cleaned, the rotary flash dryer can operate normally, reducing the production capacity of the dryer.

[0005] When the existing flash drying equipment is in use, the structure at the bottom of the tank is fixed, which reduces the contact probability between larger particle materials and the crushing parts when they fall to the bottom of the tank, resulting in a reduction in the crushing efficiency of the materials and affecting the dehydration and drying effect, and there are certain defects in use.

[0012] Preferably, a second spring is fixedly connected between the rotating seat and the hot air distribution seat evenly. The elastic film is in a stretched and wrinkled state under the rotation and torsion of the rotating seat, and when the elastic film undergoes tensile deformation under the action of air pressure, it drives the rotating seat to perform elastic rotation.

[0013] Preferably, a second blade is installed above the rotating seat, and the first blade and the second blade are in clearance fit.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1: During the use of the existing flash drying equipment for kaolin processing, large particles cannot fully contact the blades after falling to the bottom, resulting in limited crushing effect. To solve this technical problem, the following technical content is disclosed in this embodiment. Please refer to Figures 1 - 7 and Figure 10 as shown; A flash drying device for kaolin processing that can quickly dehydrate, comprising a vertically placed flash drying tank 1. A hot air distribution base 2 is fixedly installed on the outer side of the lower part of the flash drying tank 1, and an air inlet pipe 3 is fixedly connected to the outer side of the hot air distribution base 2. A discharge air pipe 4 is fixedly connected to the outer side of the upper part of the flash drying tank 1. A feeding assembly is also fixedly installed on the outer side of the flash drying tank 1. A crushing motor 8 is fixedly installed at the lower end of the hot air distribution base 2, and a rotating shaft 9 is fixedly installed at the output end of the crushing motor 8. A first blade 10 for crushing kaolin is fixedly installed on the outer side of the rotating shaft 9. A turning and throwing assembly for throwing kaolin is installed inside the hot air distribution base 2, and an air conveying assembly for driving the turning and throwing assembly is also arranged inside the hot air distribution base 2. The feeding assembly includes a feeding cylinder 5 fixedly installed through the side wall of the flash drying tank 1. A hopper 6 is fixedly communicated above the feeding cylinder 5, and a auger 7 for conveying materials is installed inside the feeding cylinder 5. The air conveying assembly includes a piston cylinder 12 fixedly installed inside the hot air distribution base 2. A piston piece 13 is installed in the piston cylinder 12 with interference fit. A pull rod 14 is fixedly installed at the upper end of the piston piece 13. The upper end of the pull rod 14 penetrates through the piston cylinder 12 and forms a lifting structure with the piston cylinder 12. A first spring 15 is fixedly connected between the inner wall of the piston cylinder 12 and the piston piece 13. The upper end of the pull rod 14 is arranged in a spherical structure. Helical guide rods 11 are symmetrically arranged on the outer side of the rotating shaft 9. During the rotation of the rotating shaft 9, the guide rods 11 rotate synchronously. As the guide rods 11 rotate, the top of the pull rod 14 is pushed to slide along the guide rods 11, so that the pull rod 14 is adjusted up and down. The lower end of the piston cylinder 12 is fixedly connected to an air pipe 16. The turning and throwing assembly includes a rotating seat 17 rotatably installed on the inner wall of the hot air distribution base 2. An elastic film 18 is fixedly connected between the rotating seat 17 and the hot air distribution base 2. The lower end of the air pipe 16 is fixedly connected to the lower part of the hot air distribution base 2. The air pipe 16 communicates the piston cylinder 12 with the closed space formed between the hot air distribution base 2 and the elastic film 18.Meanwhile, the air pipe 16 extracts the air between the hot air distribution seat 2 and the elastic film 18. The elastic film 18 is initially in a wrinkled state. When the air pipe 16 extracts the air inside both of them, the air pressure between them decreases, causing the elastic film 18 to become flat from the wrinkled state under the negative pressure, so as to realize the stretching of the elastic film 18. When the air pipe 16 conveys air between the hot air distribution seat 2 and the elastic film 18, the state of the elastic film 18 is restored. During the restoration process of the elastic film 18, the material is turned over and tossed. A second spring 19 is fixedly connected evenly between the rotating seat 17 and the hot air distribution seat 2, and the elastic film 18 is in a stretched and wrinkled state under the rotation and torsion of the rotating seat 17 (a second spring 19 is connected between the rotating seat 17 and the hot air distribution seat 2, and the rotating seat 17 rotates elastically under the elastic force of the second spring 19, so as to drive the outer ring of the elastic film 18 to rotate synchronously, and then cause the inner and outer rings of the elastic film 18 to rotate axially relative to each other, making the elastic film 18 twist and wrinkle). And when the elastic film 18 undergoes tensile deformation under the air pressure, it drives the rotating seat 17 to rotate elastically. A second blade 20 is installed above the rotating seat 17, and the first blade 10 and the second blade 20 are in clearance fit, and the rotation directions of the first blade 10 and the second blade 20 are opposite. At the same time, the first blade 10 and the second blade 20 cut the falling large-particle materials in opposite directions. The flow disturbing component includes a fixed cover 22 fixedly installed outside the rotating shaft 9, and third blades 23 are symmetrically installed on the fixed cover 22, and the lower ends of the third blades 23 are attached to the elastic film 18.

[0023] The hot air supply device connected to the outside of the air inlet pipe 3 is turned on, so that the hot air enters the inside of the flash drying tank 1 through the hot air distribution seat 2, and the auger 7 is started at the same time, so that the auger 7 can convey the kaolin raw material in the hopper 6 to the inside of the flash drying tank 1 through the feeding tube 5, and the crushing motor 8 is started at the same time, so that the crushing motor 8 drives the first blade 10 to crush the material through the rotating shaft 9, and as the rotating shaft 9 rotates, it will drive the guide rod 11 connected to the outside to rotate synchronously, so that the guide rod 11 will contact the ball on the top of the pull rod 14, As a result, the top of the pull rod 14 slides along the guide rod 11, and then the pull rod 14 drives the piston plate 13 to move up and down on the inner side of the piston cylinder 12. At this time, the piston cylinder 12 will extract the gas between the hot air distribution seat 2 and the elastic film 18 through the air pipe 16, so that there is a negative pressure between the two. At this time, the elastic film 18 will stretch downward under the action of the negative pressure (the elastic film 18 is initially wrinkled, and the elastic film 18 is made of composite rubber with good sealing and elasticity), and at the same time, the wrinkles of the elastic film 18 can be The elastic film 18 is annular in structure and wrinkled in the initial state, so there is an axial angle deviation between the inner and outer circles of the elastic film 18. When the elastic film 18 is stretched, the wrinkles of the elastic film 18 are gradually flattened, so that the outer circle rotates, thereby driving the rotating seat 17 to rotate. When the top of the pull rod 14 is separated from the highest end of the guide rod 11, the piston plate 13 will be reset, so that the air supply pipe 16 is between the hot air distribution seat 2 and the elastic film 18. The air is transmitted between the two to restore the air pressure between the two. At this time, the elastic film 18 will eject the material above it under the elastic force of its own material to realize the flipping of the material. The thrown material will move to the movement trajectory of the first blade 10, thereby realizing further crushing. At the same time, when the elastic film 18 recovers, the rotating seat 17 will elastically rotate and reset, thereby driving the second blade 20 outside it to rotate at the same time, so that the first blade 10 and the second blade 20 can cut the material in opposite directions, thereby further improving the crushing effect. Figure 11 and attached Figure 12 The letter a in the figure is located at two points where the hot air distribution seat 2 and the rotating seat 17 are relatively close to each other. The position change of the letter a can indicate the rotation change of the position of the rotating seat 17.

[0024] Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the above embodiment 1. When the existing flash drying equipment for kaolin processing is in use, the airflow is always directed upward, so that the floating time of small particles is short, and there is often a situation where they cannot be fully dried. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figures 7 - 9As shown in the figure; a spoiler assembly for realizing gas spoiler is further provided on the outer side of the rotating shaft 9. The fixed cover 22 is symmetrically ball-connected with movable spoiler plates 24. A third spring 25 is fixedly connected between the inner end of the movable spoiler plate 24 located inside the fixed cover 22 and the inner wall of the upper end of the fixed cover 22. An annular fixed ring member 21 is fixedly installed on the outer sides of the upper ends of the two pull rods 14. When the fixed ring member 21 moves upward, the inner end of the movable spoiler plate 24 located inside the fixed cover 22 is pushed to perform elastic rotation.

[0025] With the reciprocating lifting adjustment of the pull rod 14, the fixed ring member 21 provided at the top of the pull rod 14 will move upward to contact and push the inner end of the movable spoiler plate 24 located inside the fixed cover 22, so that the movable spoiler plate 24 can perform elastic rotation. During the rotation of the movable spoiler plate 24, a cyclone different from the air outlet direction of the hot air distribution seat 2 can be generated, thereby realizing the disturbance of the hot air flow, and further prolonging the floating time of the granular raw material inside the flash drying tank 1, and further improving the rapid and sufficient drying of kaolin.
