Technical Field

[0001] This utility model belongs to the field of anti-corrosion barrel technology, specifically an anti-corrosion inner-coated barrel. Background Technology

[0002] Corrosion-resistant inner-coated buckets are containers with an anti-corrosion coating applied to the inside. This coating provides multiple protective functions, such as corrosion prevention, fire prevention, antibacterial properties, heat insulation, and moisture retention. The anti-corrosion inner-coated buckets use a special anti-corrosion coating that can effectively prevent the corrosion of the bucket by pharmaceuticals, chemicals, etc., thereby extending the service life of the bucket.

[0003] Traditional methods of sealing barrels include mechanical compression to seal the lid and barrel, threaded sealing with a gasket, and welding. However, these methods are either inconvenient to open or pose a risk of leakage. Therefore, a corrosion-resistant inner-coated barrel is proposed. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4 As shown, this utility model provides an anti-corrosion inner coating bucket, including a bucket body 1. A bucket lid 2 and a fixing ring 3 are installed on the top of the bucket body 1. A pair of mounting slots 4 are provided in the middle of the fixing ring 3. A ventilation pipe 5 is fixedly connected to the bottom of the pair of mounting slots 4. Air holes 6 are opened at equal intervals in the middle of the ventilation pipe 5. An air extraction port 7 and an air inlet valve 9 are respectively installed inside the pair of mounting slots 4. A blocking fixing cover 10 is provided on the top of the air inlet valve 9. A sealing gasket 11 is fixedly connected to the lower side of the fixing ring 3.

[0021] The above scheme is adopted: the suction machine draws air outward through the air intake 7, so that the air in the gaps inside the barrel 1 is drawn to the outside of the barrel 1 through the ventilation pipe 5 and the air hole 6, so that the pressure difference between the inside and outside of the barrel 1 is formed. Through the pressure, the barrel 1 and the barrel lid 2 are pressed together to seal them.

[0022] When needed, open the blocking cover 10 and turn the air inlet valve 9. At this time, the air inlet valve 9 will connect the inside of the barrel 1 with the outside through the air pipe 5 and the air hole 6, so that the internal and external air pressure is balanced. Then, remove the fixing ring 3 to remove the barrel cover 2.

[0023] like Figure 2 and Figure 4 As shown, the mounting slots 4 are distributed in a mirror image on the top of the lid 2. The mounting slots 4 penetrate the lid 2 and extend into the interior of the body 1. All mounting slots 4 are connected to the ventilation pipe 5. The suction port 7 can be connected to an external suction machine. A one-way valve 8 is installed inside the suction port 7.

[0024] The above solution is adopted as follows: After the barrel body 1 is filled and the barrel cover 2 and fixing ring 3 are installed, the air is drawn out through the air extraction port 7 and the air is drawn out through the air pipe 5 and air hole 6, so that the barrel body 1 is in a negative pressure state. The air pressure is used to press the barrel cover 2 to ensure the seal between the barrel body 1 and the barrel cover 2.

[0025] like Figures 2 to 4 As shown, the bottom of the blocking and fixing cover 10 is provided with a limiting groove corresponding to the air intake valve 9 and is engaged with the air intake valve 9. An indicator is provided inside the mounting slot 4 at the bottom of the blocking and fixing cover 10.

[0026] Using the above solution: By setting an air inlet valve 9, when the lid 2 needs to be opened, first open the blocking and fixing cover 10, and then turn the air inlet valve 9 so that the handle of the air inlet valve 9 is rotated to the indicator inside the mounting slot 4, so that the ventilation slot at the bottom of the air inlet valve 9 is connected to the ventilation pipe 5, so that the air inside the barrel 1 is connected to the outside air, allowing air to enter the inside of the barrel 1, so that the atmospheric pressure on both sides of the lid 2 is equal, and then the fixing ring 3 can be removed, and then the lid 2 can be removed.

[0027] like Figures 1 to 4 As shown, the inside of the barrel body 1 and the side of the barrel lid 2 located inside the barrel body 1 are coated with an anti-corrosion coating. At the same time, the mounting slot 4, the ventilation pipe 5, the air extraction port 7 and the air inlet valve 9 are all treated with anti-corrosion.

[0028] The above solution involves applying an anti-corrosion coating to the barrel body 1 and the barrel lid 2, ensuring that the interior can contain corrosive materials when the barrel body 1 and the barrel lid 2 are closed. The installation slot 4, ventilation pipe 5, air extraction port 7, and air inlet valve 9 are treated to prevent corrosion by materials, which could damage the seal inside the barrel body 1 and cause leakage.

[0029] like Figure 2 and Figure 4 As shown, the lid 2 abuts against the body 1, and the sealing gasket 11 is located in the middle of the connection between the body 1 and the lid 2. The fixing ring 3 is fitted at the connection between the body 1 and the lid 2. After the suction machine is connected to the air extraction port 7, the air inside the body 1 is extracted through the air pipe 5 and the air hole 6, so that the inside of the body 2 and the lid 2 are in a negative pressure state after they are closed. The body 1 and the lid 2 are sealed by atmospheric pressure.

[0030] The above solution is adopted: by setting a sealing gasket 11, when atmospheric pressure squeezes the lid 2, the lid 2 and the sealing gasket 11 fill the gap between the lid 2 and the body 1, thereby ensuring the sealing between the body 1 and the lid 2.

[0031] The working principle and usage process of this utility model are as follows: When sealing is required, after the barrel body 1 is filled and the barrel lid 2 is closed, the fixing ring 3 is first installed and fixed. Then, the air extraction port 7 is connected to the suction machine. The suction machine draws air outward, so that the air in the gaps inside the barrel body 1 is drawn to the outside of the barrel body 1 through the ventilation pipe 5 and the air hole 6, so that a pressure difference is formed inside and outside the barrel body 1. Through the pressure, the barrel body 1 and the barrel lid 2 are pressed together to achieve sealing.

[0032] When needed, open the blocking cover 10 and turn the air inlet valve 9. At this time, the air inlet valve 9 will connect the inside of the barrel 1 with the outside through the air pipe 5 and the air hole 6, so that the internal and external air pressure is balanced. Then, remove the fixing ring 3 to remove the barrel cover 2.
