A plurality of air inlets 5 are provided on the side wall of the drying tower 1, and a feed port 6 is provided on the drying tower 1. The wet material to be dried can be introduced into the drying tower 1 through the feed port 6. The cyclone separator 2 is an existing product on the market. Its main structure comprises an air inlet pipe, a cylinder, a cone, a dust outlet, and an exhaust pipe. An air outlet pipe 7 is connected between the drying tower 1 and the cyclone separator 2. One end of the air outlet pipe 7 is connected to the drying tower 1. 1 is connected to the inner cavity of the filter bin 3, and the other end of the pipe opening is connected to the air inlet pipe of the cylinder of the cyclone separator 2. The hot air containing solid particles can be introduced into the cylinder of the cyclone separator 2 through the air outlet pipe 7. An air guide pipe 8 is connected between the filter bin 3 and the cyclone separator 2. One end of the pipe opening of the air guide pipe 8 is connected to the top exhaust pipe of the cyclone separator 2, and the other end of the pipe opening is connected to the inner cavity of the filter bin 3. The waste gas after separation and drying can be introduced into the filter bin 3 through the air guide pipe 8. The top and one side of the filter bin 3 are respectively provided with a plurality of card slots 9 and exhaust ports 10. The slot length of the card slot 9 is equal to the inner wall width of the filter bin 3. A filter assembly is arranged on the top of the filter bin 3.

[0037] The heating assembly includes a blower 11 and a heating bin 12. A blast pipe 13 is installed on the blower 11. The other end of the blast pipe 13 is fixedly connected to the bottom of the heating bin 12 and communicated with the inner cavity of the heating bin 12. By driving the blower 11, air can be blown into the heating bin 12 through the blast pipe 13. Power supply sockets 14 are installed on both sides of the inner cavity of the heating bin 12. Electric heating wires 15 are electrically connected between the power supply sockets 14. A plurality of hot air pipes 16 are fixedly connected to the top of the heating bin 12. The electric heating wires 15 can be powered by the power supply sockets 14. The electric heating wires 15 can generate heat after being energized, so as to heat the air blown out by the blower 11. The hot air can be introduced into the drying tower 1 along the air inlet 5 through the hot air pipe 16. When the hot air contacts the wet material, the moisture on the surface of the wet material can be quickly evaporated. Due to the high-speed flow of the hot air, the moisture of the material can be quickly taken away, thereby achieving instant drying.

[0038] The dispersion assembly includes a motor 17, which is installed in the drying tower 1 and is located below the partition 4. A dispersion shaft 18 is installed at the output end of the motor 17. The dispersion shaft 18 passes through the partition 4, and a plurality of dispersion sheets 19 are fixedly connected to the shaft body. The dispersion shaft 18 can be driven to rotate together with each dispersion sheet 19 by driving the motor 17. When the dispersion sheet 19 rotates, the wet material in the drying tower 1 can be dispersed to form fine particles.

[0039] The filter assembly includes a cover plate 20, a handle 21 is fixedly connected to the top of the cover plate 20, and a plurality of filter screens 22 are installed at the bottom of the cover plate 20. The filter screen 22 can be a HEAP filter screen. When the exhaust gas enters the filter bin 3, each filter screen 22 can effectively absorb and filter a small amount of dust and other impurities remaining in the exhaust gas, thereby avoiding the exhaust gas from being directly discharged into the atmosphere and causing pollution to the environment.

[0040] Among them, the hot air pipes 16 are distributed in an equidistant ring shape along the circumferential direction of the heating chamber 12, and one end of each hot air pipe 16 is connected to the inner cavity of the heating chamber 12. The hot air in the heating chamber 12 can be diverted through multiple hot air pipes 16 so as to be introduced into each air inlet 5.

[0041] Among them, the number of air inlets 5 is the same as that of hot air pipes 16, and the center of each air inlet 5 corresponds to the center of each hot air pipe 16 one by one. Each hot air pipe 16 can be aligned with and inserted into the corresponding air inlet 5. After the hot air is diverted by each hot air pipe 16, it can enter the drying tower 1 from multiple angles through each air inlet 5, so that the hot air can be fully and evenly diffused to the entire drying tower 1, thereby effectively avoiding the generation of drying dead corners in the drying tower 1 and causing the material to be dried incompletely.

[0042] Among them, an anti-blocking cover 23 is installed on each air inlet 5, the end diameter of the anti-blocking cover 23 is equal to the inner diameter of the air inlet 5, and a blocking net 24 is installed at the end of the anti-blocking cover 23. The anti-blocking cover 23 can be inserted into the air inlet 5 and fit against the inner wall of the air inlet 5. When the hot air pipe 16 is inserted into the air inlet 5, it can fit against the inner wall of the anti-blocking cover 23. At this time, the material particles can be blocked by the blocking net 24 to avoid the material particles entering the hot air pipe 16 during the dispersion process and causing blockage.

[0043] Among them, the dispersion pieces 19 are equidistantly linearly distributed along the axial direction of the dispersion axis 18, and each group of dispersion pieces 19 is equidistantly annularly distributed along the circumferential direction of the dispersion axis 18. A plurality of blades 25 are arranged on both sides of each dispersion piece 19, and the blades 25 are equidistantly linearly distributed along the length direction of the dispersion piece 19. The contact range between the agglomerated material and the dispersion component can be effectively increased by multiple groups of dispersion pieces 19, and the extrusion force applied by the dispersion piece 19 to the agglomerated material can be further increased by each blade 25, so as to completely decompose the easily agglomerated material so that it can fully contact with the hot air, thereby effectively improving the drying effect of the flash dryer.

[0044] Among them, the end of each dispersion piece 19 is fixedly connected to a cleaning block 26, the side of the cleaning block 26 is arc-shaped, and a layer of cleaning brush 27 is arranged on the arc-shaped end surface of the cleaning block 26. When each dispersion piece 19 rotates with the dispersion shaft 18, the cleaning block 26 can drive the cleaning brush 27 to scrape back and forth along the inner wall surface of the drying tower 1. At this time, the cleaning brush 27 can be used to clean the inner wall of the drying tower 1, thereby effectively avoiding the particulate impurities adhering to the inner wall of the drying tower 1 and being difficult to clean in time.

[0045] Among them, the number of filter screens 22 is the same as the slots 9, and their width and thickness are respectively equal to the slot length and slot width of the slots 9, and the center of each filter screen 22 corresponds to the center of each slot 9. When the cover plate 20 is covered on the top of the filter bin 3, each filter screen 22 can be aligned and inserted into the corresponding slot 9. At this time, each filter screen 22 is attached to the inner wall of the filter bin 3. When the exhaust gas enters the filter bin 3, multiple filter screens 22 can be used to filter the exhaust gas for multiple times, thereby further improving the filtering effect of the exhaust gas.

[0046] The circuits, electronic components and chip modules involved in the utility model are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to software and methods.

[0047] The standard parts used in the application documents can all be purchased from the market. All the components in this application document can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt mature conventional means such as bolts, rivets, welding, etc. in the prior art. Machinery, parts and equipment all adopt conventional models in the prior art. The electrical components appearing in this article are all electrically connected to the external main controller and 220V AC power, and the main controller can be a conventional known device that controls the LED lamp body, etc.

[0048] The working principle of the utility model is:

[0049] When the utility model is used, firstly, the electrical components in the flash dryer are connected to the control switch and the power supply through the wires, and then the wet material to be dried is introduced into the drying tower 1 through the feed port 6. At the same time, the driving motor 17 drives the dispersion shaft 18 to rotate together with each dispersion sheet 19. When the dispersion sheet 19 rotates, the wet material in the drying tower 1 can be dispersed to form fine particles. Then, the electric heating wire 15 is powered by the power supply seat 14, and the blower 11 is driven to blow air into the heating bin 12 through the blast pipe 13. After the electric heating wire 15 is energized, heat can be generated to heat the air blown by the blower 11. Then, the hot air can be introduced into the drying tower 1 along the air inlet 5 through the hot air pipe 16. When the hot air contacts the dispersed fine wet material particles, the moisture on the surface of the wet material can be quickly evaporated. Due to the high-speed flow of the hot air, the moisture of the material can be quickly taken away. Instant drying is thereby achieved, and the dried material is introduced into the cylinder of the cyclone separator 2 along the air flow generated by the hot air along the air outlet pipe 7, and the air flow forms a high-speed rotating vortex in the cylinder of the cyclone separator 2. Due to the rotation of the air flow, the material particles are thrown to the inner wall of the cylinder under the action of centrifugal force, and move downward along the inner wall of the cylinder under the action of centrifugal force, and finally enter the cone of the cyclone separator 2 and are discharged from the dust exhaust port at the bottom of the cone, while the rotating air flow gradually moves toward the center of the cylinder of the cyclone separator 2, and after forming an ascending air flow, it is introduced into the filter bin 3 through the top air guide pipe 8. When the exhaust gas enters the filter bin 3, it will contact each filter screen 22. At this time, each filter screen 22 can effectively adsorb and filter a small amount of impurities such as dust remaining in the exhaust gas, thereby avoiding the exhaust gas being directly discharged into the atmosphere and causing pollution to the environment, and then the filtered exhaust gas can be discharged through the exhaust port 10.
