[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] Combined with Figure 1-3 A long-term storage device for a leveling agent comprises a sealed storage tank body 1, wherein the top and bottom of the sealed storage tank body 1 are respectively connected with a feeding pipe port 2 and a discharging pipe port 4, wherein the ends of the feeding pipe port 2 and the discharging pipe port 4 are respectively connected with a first sealing cover 3 and a second sealing cover 5, wherein the feeding pipe port 2 and the discharging pipe port 4 can be used for feeding and discharging operations, and the first sealing cover 3 and the second sealing cover 5 can ensure the sealing operation inside the sealed storage tank body 1, wherein the top of the sealed storage tank body 1 is connected with an air pump 6, wherein the air pump 6 is connected with an air pump 7 extending into the sealed storage tank body 1 and an air pump 7 extending to the sealed storage tank body 1. The external exhaust pipe 8, the top of the sealed storage tank body 1 is connected to a filter box 26 that wraps the exhaust pipe 7, the bottom of the filter box 26 is connected to a second filter mesh 27, and the exhaust pipe 8 is connected to a first electric control valve 9. The inside of the sealed storage tank body 1 can be vacuumed by the vacuum pump 6. In daily operations, sealing operations can be performed through the first electric control valve 9. During the extraction process, the second filter mesh 27 can prevent the leveling agent from being extracted when exhausting. The mesh size of the second filter mesh 27 needs to be smaller than the size of the leveling agent. When the effect is not good, a cloth cover can be added to prevent the leveling agent from being extracted.

[0020] In specific implementation: when the leveling agent needs to be stored, the leveling agent is placed in the sealed storage tank body 1, and the internal air can be extracted by starting the vacuum pump 6 to ensure the internal vacuum state, thereby ensuring long-term storage operations.

[0021] The outer side of the sealed storage tank body 1 is connected to a dry adsorption box 15, one side of the dry adsorption box 15 is provided with an air inlet 20, the outer side of the dry adsorption box 15 is connected to an air collecting hood 21 that matches the air inlet 20, the air collecting hood 21 is connected to a third electric control valve 23, the inside of the dry adsorption box 15 is connected to a desiccant adsorption layer 24 between the air inlet 20 and the air delivery pipe 16, the dry adsorption box 15 is connected to a supporting mesh plate 25 that clamps the desiccant adsorption layer 24, and the other side is connected to the air delivery pipe 16, the dry adsorption box 15 is connected to a supporting mesh plate 25 that clamps the desiccant adsorption layer 24, and the other side is connected to the air delivery pipe 16. The auxiliary box 15 can supply dry gas to multiple sealed storage tank bodies 1 in one box, so that multiple corresponding gas pipes 16 can also be set. The end of the gas pipe 16 is connected with an air dividing ring 17, and the top of the gas dividing ring 17 is connected with multiple air guide pipes 18 connected to the sealed storage tank body 1. The bottom of the sealed storage tank body 1 is connected with a first filter mesh 19 that cooperates with the air guide pipe 18. The first filter mesh 19 is consistent with the second filter mesh 27 to prevent the leveling agent from leaking out. The gas pipe 16 is connected with a second electric control valve 22.

[0022] During specific implementation: because the leveling agent itself will bring in humid gas when it is added, dry gas can be input from the bottom when the vacuum is drawn, so as to prevent humid gas from accumulating inside the sealed storage tank body 1. At the same time, multiple electric control valves are arranged in this device, and an external controller is required to control the start and stop of the electric control valve. At the same time, the controller can be provided with a sensor to sense the temperature, humidity and pressure inside the sealed storage tank body 1. This is a common existing technology, so it will not be elaborated.

[0023] A motor 10 is connected to the middle of the top of the sealed storage tank body 1, and a rotating shaft 11 extending into the sealed storage tank body 1 is connected to the bottom power end of the motor 10. An auger blade 12 is welded to the outside of the rotating shaft 11. A first supporting bearing frame 13 matching the rotating shaft 11 is connected to the top of the sealed storage tank body 1, and a second supporting bearing frame 14 matching the rotating shaft 11 is connected to the bottom of the sealed storage tank body 1.

[0024] In specific implementation: because the leveling agent is in a piled state, when the dry gas is input at the bottom, it cannot be input upward evenly and completely, so the motor 10 is set to drive the auger blade 12 to turn the material, thereby cooperating with the input operation of the dry gas.

[0025] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
