[0002] A pressure vessel is a closed container that can withstand pressure. It has a wide range of uses and plays an important role in many sectors such as industry, civil, and military, as well as many fields of scientific research. It is most widely used in the chemical industry and petrochemical industry. The pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels. It is mainly used in processes such as heat transfer, mass transfer, and reaction, as well as the storage and transportation of pressurized gas or liquefied gas. The preparation of pressure vessels generally includes the following steps: steel plate cutting, component welding, flaw detection, assembly welding, pressure testing, surface treatment, etc., among which surface treatment is the last step of production work. This step often uses a sandblasting machine to perform surface sandblasting on the processed pressure vessel, which removes rust and improves the surface finish. Sandblasting rust removal is to use a sandblasting device to remove rust, use the jet force and the friction of the sand to clean and rust the surface of the object, and use the high-speed sand to hit, rub, and cut to remove rust.

A screw is set in the rust removal chamber 1. The screw passes through the scraper plate 14 and is connected to the scraper plate 14 through a thread. A motor connected to the screw is installed outside the rust removal chamber 1. The screw can be driven to rotate by the motor, and then the scraper plate 14 is driven to move by the thread. Other forms of driving structures can also be selected according to actual conditions.

[0019] The utility model is used for sandblasting and rust removal on the surface of a container. When in use, the side door 2 is first opened to move the mobile trolley 4 out of the rust removal chamber 1, the container to be sandblasted and rust removed is placed on the bracket 5 of the mobile trolley 4 and fixed, the mobile trolley 4 moves along the track 3 until it brings the container into the rust removal chamber 1, the side door 2 is closed, the upper sliding trolley 7 drives the upper arc tube 8 to move horizontally, the sand and gravel enter the upper arc tube 8, and then are sprayed out from the upper sandblasting gun 9 to sandblast and rust remove the upper part and both sides of the container, and at the same time At the same time, the side sliding trolley 11 drives the side arc tube 12 to move up and down along the side slide 10, and the gravel enters the side arc tube 12, and is then sprayed out from the side sandblasting gun 13 to perform sandblasting and rust removal on both ends of the container. After the sandblasting and rust removal of the container is completed, the container is moved out of the rust removal chamber 1, and the driving mechanism is started. The driving mechanism drives the scraper plate 14 to translate. During the translation process, the scraper plate 14 drives the gravel that falls on the bottom of the rust removal chamber 1 to move until the gravel is pushed to the sand storage tank 15, thereby completing the collection of the gravel. In the utility model, the sandblasting and rust removal process of the container is automatically performed by the upper sandblasting mechanism and the side sandblasting mechanism, wherein the upper sandblasting mechanism performs sandblasting and rust removal on the upper part and both sides of the container, and the side sandblasting mechanism performs sandblasting and rust removal on both ends of the container, and no manual operation is required. On the one hand, it can greatly improve work efficiency, shorten the time for sandblasting and rust removal, and thus shorten the production period of the container and improve economic benefits. On the other hand, the entire sandblasting and rust removal work is performed by the corresponding sandblasting mechanism, avoiding human factors such as proficiency problems, technical problems, and emotional changes that may occur during manual operation, and the rust removal effect is better. The rust removal effect is relatively stable; secondly, when the container is rust-removed by the utility model, it is placed in a closed rust removal chamber 1, and the sprayed sand and gravel will not spread to the surrounding environment, so there will be no waste of sand and gravel, and no pollution to the environment. The corresponding sandblasting mechanism is used for automatic sandblasting, which will not cause harm to the health of the workers. At the same time, after completing a sandblasting process, the sand scraper 14 can push the sand and gravel that falls into the rust removal chamber 1 to the sand storage tank 15, so as to realize automatic collection of the sand and gravel, which is convenient and fast, avoids the manual cleaning of the sand and gravel, improves the work efficiency of the sandblasting operation, and reduces the labor cost.

[0020] The movable trolleys 4 on both sides of the bracket 5 are provided with lower sandblasting mechanisms, which include a lower slide 16 and a lower sliding carriage 17 installed on the lower slide 16, and a lower sandblasting gun 18 is provided on the lower sliding carriage 17 tilted upward. This system uses an upper sandblasting mechanism and a side sandblasting mechanism to achieve rust removal on the surface of the container, wherein the upper sandblasting mechanism is used to sandblast the upper part and both sides of the container, and the side sandblasting mechanism is used to sandblast the flat covers or heads at both ends of the container. Although the sandblasting range of the upper sandblasting mechanism can also cover a certain range of the lower part of the container, it is not comprehensive, resulting in poor rust removal effect on the lower part and bottom of the container, and local rust removal is often required later. In order to solve this problem, a lower sandblasting mechanism is provided. When in use, the sand and gravel are tilted from the lower sandblasting gun 18 to the lower part and bottom of the container, and combined with the upper sandblasting mechanism and the side sandblasting mechanism, the sandblasting range of the container surface is fully covered, and the effect and efficiency of sandblasting and rust removal on the container surface are improved.

[0021] The side slide 10 is arc-shaped, and the middle of the side slide 10 and the side arc-shaped tube 12 protrude toward the outside of the rust removal chamber 1. Considering that the two ends of the container are mostly convex head structures such as elliptical heads and spherical heads, and the outer surface has a certain curvature, the side slide 10 and the side arc-shaped tube 12 are both set to be arc-shaped, so that the distance between each side sandblasting gun 13 and the outer surface of the convex head is equivalent, thereby ensuring that each part of the convex head can obtain a good sandblasting and rust removal effect.

[0022] In order to meet the sandblasting and rust removal needs of containers of various diameters, a cylinder 19 is installed on the top of the rust removal chamber 1, and the piston rod end of the cylinder 19 is extended into the rust removal chamber 1 and connected to the upper slide 6. When the diameter of the container is small, the upper slide 6 is driven downward by the cylinder 19, and vice versa, when the diameter of the container is large, the upper slide 6 is driven upward by the cylinder 19, so that the distance between the upper sandblasting gun 9 and the container surface is moderate, which can achieve a better sandblasting and rust removal effect.

[0023] A sand storage box 20 is provided outside the rust removal chamber 1. The sand storage box 20 is connected to the sand storage tank 15 through a sand delivery pipeline, and a pressure pump is provided on the sand delivery pipeline. The system scrapes the sand and gravel falling on the bottom of the rust removal chamber 1 to the sand storage tank 15 through a sand scraper 14. After a period of use, the sand and gravel in the sand storage tank 15 need to be cleaned. In order to improve the cleaning efficiency of the sand and gravel, the sand and gravel are sent to the sand storage box 20 for storage through a sand delivery pipeline provided with a pressure pump, which is convenient for subsequent unified processing.

[0024] An exhaust pipe is provided at the top of the rust removal chamber 1, and an exhaust fan 21 and a dust removal device 22 are provided on the exhaust pipe in sequence. The dust exhaust port of the dust removal device 22 is connected with the sand storage box 20 through a pipeline. During the sandblasting process of the container, this system will generate a large amount of dust. In order to prevent the dust from polluting the surrounding environment, the dust is sucked into the dust removal device 22 through the exhaust pipe under the action of the exhaust fan 21. The dust removal device 22 is a prior art, which can separate the sand and gravel entrained in the air to purify the air. At the same time, the separated sand and gravel are transported to the sand storage box 20 for recycling and reducing the waste of sand and gravel.

[0025] In order to adapt to the sandblasting and rust removal of containers of various diameters, a vertical slide 23 is provided on the side door 2 and the side wall of the rust removal chamber 1 opposite to the side door 2, and a shift trolley 24 is provided on the side slide 10 of the side sandblasting mechanism. The shift trolley 24 is slidably installed on the vertical slide 23. The shift trolley 24 is a prior art with its own drive and can move on the vertical slide 23. When it is necessary to perform sandblasting and rust removal on a container with a larger diameter, the center of the container moves upward, and the shift trolley 24 is controlled to move upward along the vertical slide 23. Conversely, when it is necessary to perform sandblasting and rust removal on a container with a smaller diameter, the center of the container moves downward, and the shift trolley 24 is controlled to move downward along the vertical slide 23. Generally, the center of the side slide 10 needs to be concentric with the container to be sandblasted to ensure that the sandblasting range of the side sandblasting gun 13 can completely cover the surfaces of both ends of the container, thereby ensuring that both ends of the container can obtain better sandblasting and rust removal effects.
