Description

Technical Field

[0001] This utility model relates to the field of aluminum powder paste storage technology, and in particular to an aluminum powder paste storage bin. Background Technology

[0002] Aluminum powder paste, also known as aerated aluminum powder, is mainly used in the production process. During production, the aluminum powder in the paste reacts chemically with silica and quicklime to release gas, creating a porous structure within the resulting concrete blocks. Aluminum powder paste should be stored in a dry environment to avoid contact with water, acids, and alkalis, thus reducing the oxidation and degradation of the aluminum powder. For example, utility model patent CN216784311U describes a water-based aluminum powder paste production and storage device that uses hygroscopic asbestos to prevent moisture intrusion. However, when storing aluminum powder paste in a silo, the paste arches during discharge, hindering smooth discharge. Utility model patent CN211197294U describes an aluminum powder storage tank that increases air pressure inside the tank to assist discharge and ensure smooth discharge; however, directly introducing external air can easily introduce moisture into the aluminum powder paste, which is detrimental to its storage. Utility Model Content

[0003] The purpose of this invention is to provide an aluminum powder paste storage bin in order to solve the problem of moisture introduction during pressurized discharge of storage devices.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An aluminum powder paste storage silo includes a silo body, an air pump, and an air guide pipe. The silo body stores aluminum powder paste. The upper and lower ends of the silo body are respectively connected to an inlet pipe and a outlet pipe, and a first valve is installed on both the inlet pipe and the outlet pipe. The air pump delivers air to the upper part of the silo body through the air guide pipe, thereby increasing the air pressure inside the silo body. An oxygen adsorption cylinder and a drying cylinder are installed on the air guide pipe. The oxygen adsorption cylinder contains an oxygen adsorbent to adsorb oxygen from the air. The drying cylinder contains a desiccant to adsorb moisture from the air.

[0005] Furthermore, both the oxygen adsorption cylinder and the drying cylinder include a mesh cylinder connected in series with the gas guide tube, and the outer side of the mesh cylinder is provided with an outer shell, with a gap between the outer shell and the mesh cylinder for storing oxygen adsorbent or desiccant.

[0006] Furthermore, a safety valve is installed at the upper end of the chamber.

[0007] Furthermore, a dust collection hood is provided on the outer side of the lower end of the discharge pipe, and two air inlet pipes are connected to the air pump input end, one of which is connected to the dust collection hood.

[0008] Furthermore, each of the intake pipes is equipped with a second valve.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses an oxygen adsorption cylinder and a drying cylinder to adsorb oxygen and moisture from the air. During pressurized discharge, it reduces the entry of harmful gases into the silo, ensures a dry storage environment for aluminum powder paste, and prevents aluminum powder paste from becoming ineffective. The air pump of this invention can absorb air at the discharge pipe through the air inlet pipe and the dust collection hood located at the discharge pipe, thereby collecting the powder generated during the discharge process, preventing the aluminum powder paste from being released into the air, and ensuring the safety of the storage environment.

[0019] The present invention will be further described in detail below with reference to the embodiments.

[0020] Specific embodiments of the aluminum powder paste storage bin provided by this utility model: Please see Figure 1-3 The aluminum powder paste storage silo includes a silo body 1, an air pump 5, an air guide pipe 6, an oxygen adsorption cylinder 7, and a drying cylinder 8. The silo body 1 stores the aluminum powder paste. The lower end of the silo body 1 is conical, and support legs are installed on its underside. The upper and lower ends of the silo body 1 are respectively connected to an inlet pipe 2 and a outlet pipe 3. Both the inlet pipe 2 and the outlet pipe 3 are equipped with a first valve 4. Opening the first valve 4 facilitates the feeding and discharging of the aluminum powder paste into the silo body 1, while closing the first valve 4 ensures that the aluminum powder paste inside the silo body 1 is sealed and not exposed to the outside environment.

[0021] A dust collection hood 10 is installed on the outer side of the lower end of the discharge pipe 3. The input end of the air pump 5 is connected to two air inlet pipes 11. One air inlet pipe 11 is connected to the dust collection hood 10, and the outlet of the other air inlet pipe 11 is in the air. Each air inlet pipe 11 is equipped with a second valve 12. The two second valves 12 can be opened one at a time or both at the same time. When the discharge pipe 3 discharges material, the generated aluminum powder paste is sucked into the dust collection hood 10 and guided into the air guide pipe 6 through the air inlet pipe 11 and the air pump 5; this prevents the powder from dispersing into the air and ensures the safety of the storage environment.

[0022] The output end of the air pump 5 is connected to the upper part of the chamber 1 through the air guide pipe 6. The air pump 5 delivers air to the upper part of the chamber 1 through the air guide pipe 6, thereby increasing the air pressure inside the chamber 1. This applies pressure to the aluminum powder paste from the top during material discharge, assisting in material discharge.

[0023] A safety valve 9 is installed at the upper end of the chamber 1. When the pressure is too high and exceeds the threshold of the safety valve 9, the safety valve 9 will release pressure to ensure the safety of the chamber 1.

[0024] An oxygen adsorption cylinder 7 and a drying cylinder 8 are installed on the air delivery pipe 6. The oxygen adsorption cylinder 7 contains an oxygen adsorbent to adsorb oxygen from the air; the drying cylinder 8 contains a desiccant to adsorb moisture from the air. Both the oxygen adsorption cylinder 7 and the drying cylinder 8 include a mesh cylinder 102 connected in series with the air delivery pipe 6. The mesh cylinder 102 has an outer shell 101 on its outer side. There is a gap between the outer shell 101 and the mesh cylinder 102 for storing the oxygen adsorbent or desiccant. The side wall of the mesh cylinder 102 has holes to allow air to come into contact with the desiccant or oxygen adsorbent.

[0025] In this embodiment, molecular sieves are used as oxygen adsorbents and silica gel particles are used as desiccants. Outside air enters the chamber 1 through the drying cylinder 8 and the oxygen adsorption cylinder 7 in sequence, effectively drying the air and reducing the oxygen content, thus preventing the aluminum powder in the internal aluminum powder paste from oxidizing and failing due to the introduction of moisture-laden air.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
