[0066] Hot air component, the hot air component is fixed on the tower body 1, and the hot air component is connected to the drying component;

[0067] Among them, the drying component includes:

[0068] The drying seat 15 is fixed in the drying tank 3. The top and bottom of the drying seat 15 are provided with through holes, and the drying seat 15 is connected to the drying assembly;

[0069] The sealing component is fixed in the drying tank 3 and is used to control the opening and closing of the two through holes.

[0070] Through the operation of the sealing assembly, the drying tank 3 can be connected with the storage tank 2 and the granulation tank 4, thereby realizing the synchronization of granulation and drying. In this process, the drying tank 3 and the granulation tank 4 are in a sealed state, thereby avoiding the powder that has just been granulated from being mixed with the powder in the drying process, thereby ensuring the quality of the powder after drying.

[0071] Furthermore, the sealing assembly includes:

[0072] A second retaining ring 23 is provided on the top inner wall of the drying seat 15;

[0073] A first retaining ring 24 is fixed to the bottom inner wall of the drying seat 15;

[0075] A first baffle 21, the first baffle 21 is arranged below the first baffle ring 24;

[0076] A connecting assembly is connected to the first baffle 21 and the second baffle 22 .

[0077] Furthermore, the connection component includes:

[0078] The sleeve 20 is provided through the top of the first baffle 21;

[0079] a sleeve rod 26 slidably disposed within the sleeve 20;

[0080] Spring 25 is fixed on the inner wall of sleeve 20, and spring 25 and sleeve rod 26 are fixed.

[0081] Furthermore, it also includes:

[0082] Bracket 27, bracket 27 is fixed on the inner wall of the drying tank 3;

[0083] The electric push rod 19 is fixed to the top of the bracket 27, and the telescopic end of the electric push rod 19 is fixed to the sleeve 20.

[0084] When the electric push rod 19 is in operation, it drives the sleeve 20 upward. During the upward movement of the sleeve 20, the first baffle 21 is driven to contact the first retaining ring 24, thereby sealing the bottom of the drying seat 15. At the same time, the second baffle 22 is driven away from the second retaining ring 23 by the action of the spring 25 and the sleeve rod 26, thereby allowing the powder at the bottom of the granulation tank 4 to enter the drying seat 15 through the guide bucket 17. Since the hot air is injected into the drying seat 15 through the air inlet pipe 28, the powder is dried in the drying seat 15. When the powder in the drying seat 15 is dried, the switch of the electric push rod 19 is turned on again. When the electric push rod 19 is in operation, it drives the sleeve 20 downward. When the sleeve 20 descends, the second baffle 22 first contacts the second retaining ring 23, sealing the granulation tank 4 and the drying tank 3 to prevent the powder from entering the drying seat 15. Then, the sleeve 20 descends and stretches the spring 25, which can move the first baffle 21 away from the first retaining ring 24, thereby allowing the powder in the drying seat 15 to fall into the storage tank 2 for storage.

[0085] Furthermore, it also includes:

[0086] A second annular filter 30 is fixed on the inner wall of the drying seat 15;

[0087] Multiple connecting pipes 16 are provided on the top of the drying seat 15, and the connecting pipes 16 and the second baffle 22 are located on both sides of the second annular filter 30. Each connecting pipe 16 passes through the inner wall of the granulation tank 4, and a nozzle 18 is fixed at the end of each connecting pipe 16;

[0088] The guide bucket 17 is fixed on the top of the drying seat 15, and the guide bucket 17 and the bottom inner wall of the drying tank 3 are fixed.

[0089] Furthermore, the hot air component includes:

[0090] An air pump box 8 is fixed to the tower body 1 and contains an air pump;

[0091] The air delivery pipe 9 is arranged on the output port of the air pump;

[0092] The connecting seat 29 is fixed in the drying tank 3, the connecting seat 29 is connected to the gas pipe 9, and a heating wire is provided in the connecting seat 29;

[0093] Multiple air inlet pipes 28 are arranged through the top of the connecting seat 29, and each air inlet pipe 28 passes through the bottom inner wall of the drying seat 15.

[0094] Furthermore, the granulation assembly includes:

[0095] The input pipe 7 is provided through the top of the granulation tank 4, and a dispersion mechanism is provided at the bottom of the input pipe 7.

[0096] Turn on the switches of the air pump and the heating wire, and the slurry is sprayed into the granulation tank 4 through the dispersion mechanism at the bottom of the input pipe 7. When the air pump is working, the gas is injected into the connecting seat 29 through the air pipe 9. Through the heating of the heating wire in the connecting seat 29, it is then injected into the drying seat 15 through the air inlet pipe 28, and then passes through the second annular filter 30, and is input into the granulation tank 4 through the connecting pipe 16 and the nozzle 18. The gas output through the nozzle 18 convects with the dispersed slurry, quickly evaporating the moisture in the slurry, thereby realizing the granulation work.

[0097] Furthermore, the filtering component includes:

[0098] The separation seat 5 is fixed on the top of the granulation tank 4;

[0099] A first annular filter screen 11, the first annular filter screen 11 is fixed in the separation seat 5;

[0100] Multiple guide pipes 12 are arranged on the inner wall of the separation seat 5, and each guide pipe 12 passes through the first annular filter 11. Each guide pipe 12 is connected to the tower body 1. Multiple through holes 6 are opened on the top of the separation seat 5, and each through hole 6 is in the first annular filter 11.

[0101] Furthermore, a valve 10 is fixed at the bottom of the storage tank 2, a plurality of solenoid valves 13 are provided through the bottom of the separation seat 5, a plurality of reflux pipes 14 are provided through the top of the granulation tank 4, and the plurality of reflux pipes 14 are connected to the plurality of solenoid valves 13 one to one.

[0102] The gas in the granulation tank 4 enters the space on the side of the first annular filter 11 in the separation seat 5 through the guide pipe 12, and is filtered by the first annular filter 11 and output through the through hole 6. When the amount of powder in the separation seat 5 reaches a certain level, the switch of the solenoid valve 13 is turned on, and the powder in the separation seat 5 flows back to the granulation tank 4 through the solenoid valve 13 and the reflux pipe 14 to realize the reflux of the powder.

[0103] The specific working method is as follows: when in use, the input pipe 7 is connected to the feeding device, and the switches of the air pump and the electric heating wire are turned on. The slurry is sprayed into the granulation tank 4 through the dispersion mechanism at the bottom of the input pipe 7. When the air pump is working, the gas is injected into the connecting seat 29 through the air delivery pipe 9. After being heated by the electric heating wire in the connecting seat 29, the gas is then injected into the drying seat 15 through the air inlet pipe 28, passes through the second annular filter 30, and is input into the granulation tank 4 through the connecting pipe 16 and the nozzle 18. The gas output by the nozzle 18 convects with the dispersed slurry, quickly evaporating the moisture in the slurry, thereby achieving granulation.

[0104] The powder generated during the granulation process accumulates at the bottom of the granulation tank 4. As the working time increases, the switch of the electric push rod 19 is turned on. When the electric push rod 19 works, it drives the sleeve 20 to rise. During the rising process of the sleeve 20, the first baffle 21 is driven to contact the first baffle ring 24, thereby sealing the bottom of the drying seat 15. At the same time, the second baffle 22 is driven away from the second baffle ring 23 by the action of the spring 25 and the sleeve rod 26, so that the powder at the bottom of the granulation tank 4 enters the drying seat 15 through the guide bucket 17. Since the hot air is injected into the drying seat 15 through the air inlet pipe 28, the powder is dried in the drying seat 15. After the powder in the drying seat 15 is dried, the switch of the electric push rod 19 is turned on. When the electric push rod 19 works, it drives the sleeve 20 to descend. When the sleeve 20 descends, the second baffle 22 first conflicts with the second retaining ring 23, sealing the granulation tank 4 and the drying tank 3 to prevent the powder from entering the drying seat 15. Then, the sleeve 20 descends and stretches the spring 25, which can make the first baffle 21 move away from the first retaining ring 24, thereby allowing the powder in the drying seat 15 to fall into the storage tank 2 for storage.

[0105] Open valve 10 to achieve the output of powder;

[0106] The gas in the granulation tank 4 enters the space on the side of the first annular filter 11 in the separation seat 5 through the guide pipe 12, and is filtered by the first annular filter 11 and output through the through hole 6. When the amount of powder in the separation seat 5 reaches a certain level, the switch of the solenoid valve 13 is turned on, and the powder in the separation seat 5 flows back to the granulation tank 4 through the solenoid valve 13 and the reflux pipe 14 to realize the reflux of the powder.
