Description

Technical Field

[0001] The utility model relates to the technical field of cryogenic pressure vessels, and particularly relates to a cleaning device for the inner and outer walls of semi-finished cryogenic pressure vessels. Background Technique

[0002] A cryogenic pressure vessel (low-temperature adiabatic tank) is a storage container for storing cryogenic liquid gases. Its structure includes an inner container and an outer container sleeved outside the inner container. A number of support columns are arranged between the inner container and the outer container, so as to form an interlayer space between the inner container and the outer container. Due to good safety and heat insulation performance, cryogenic pressure vessels are widely used in the industrial field. In a typical double-layer cryogenic pressure vessel, its inner tank is a stainless-steel inner tank, and the outer tank is a carbon steel or alloy steel inner tank. During the manufacturing process of the double-layer cryogenic pressure vessel, it is necessary to clean the inner and outer walls of the semi-finished cryogenic pressure vessel, especially the long pipe parts at the left and right connectable ends in the middle part. After retrieval, the patent with the publication number CN216323984U discloses a cleaning device for the inner and outer walls of semi-finished cryogenic pressure vessels. Its grid-type cleaning platform is provided with vibration energy plates, and the vibration energy plates can transmit vibration energy to the cryogenic pressure vessel. When water jet cleaning is carried out, the water flow remaining on the tank wall of the cryogenic pressure vessel is subjected to the action of vibration energy to generate cavitation, forming a vibration cleaning effect, thereby improving the cleaning efficiency and quality. However, this kind of cleaning is prone to water splash, which is likely to cause pollution to the cleaning environment and waste of water. At the same time, due to the long and heavy long pipe part of the semi-finished cryogenic pressure vessel, by causing its vibration and forming a vibration cleaning method with the water jetting on its surface, the energy consumption is relatively high. If it is directly immersed in an ultrasonic cleaning tank for cleaning, a relatively large ultrasonic cleaning tank needs to be customized, and at the same time, its operating energy consumption is also relatively large, and the economic effect is relatively poor. Therefore, a cleaning device for the inner and outer walls of semi-finished cryogenic pressure vessels is designed, which can use a relatively shallow ultrasonic cleaning tank to complete the cleaning of the long pipe part in the semi-finished cryogenic pressure vessel, ensure clean cleaning while reducing energy consumption, and there is no water splash, that is, it does not pollute the surrounding environment and reduces the waste of water resources.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a device for cleaning the inner and outer walls of a semi-finished cryogenic pressure vessel, which has the following beneficial effects:

[0015] The semi-finished product inner and outer wall cleaning device for cryogenic pressure vessels is equipped with a rotating conveying screw, which facilitates horizontally picking up the long tube part of the semi-finished cryogenic pressure vessel. Through the lifting drive structure, the rotating conveying screw and the long tube part of the semi-finished cryogenic pressure vessel picked up horizontally on the rotating conveying screw can be driven to lift as a whole, thus conveniently immersing the outer and inner sides of the bottom of the long tube part of the semi-finished cryogenic pressure vessel into the cleaning liquid in the ultrasonic cleaning tank. Then, through the rotation drive structure, it is convenient to drive the rotating conveying screw to rotate. Due to the frictional force between the long tube part of the semi-finished cryogenic pressure vessel and the rotating conveying screw and the self-gravity part of the long tube part of the semi-finished cryogenic pressure vessel, while the long tube part of the semi-finished cryogenic pressure vessel is being conveyed outward, it is driven to rotate, so that the entire long tube part of the semi-finished cryogenic pressure vessel can be slowly and evenly immersed into the cleaning liquid in the ultrasonic cleaning tank. Therefore, a relatively deep and large ultrasonic cleaning tank is not required to ensure the cleaning of the long tube part of the semi-finished cryogenic pressure vessel, and during the cleaning process, no water stains splash out. By setting the loading and unloading structure on the other side, it is convenient to load materials onto the rotating conveying screw and unload them after cleaning. The semi-finished product inner and outer wall cleaning device for cryogenic pressure vessels can use a relatively shallow ultrasonic cleaning tank to complete the cleaning of the long tube part of the semi-finished cryogenic pressure vessel, ensuring clean cleaning while reducing energy consumption and without water stains splashing out, that is, it does not pollute the surrounding environment and reduces the waste of water resources.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment:

[0023] Please refer to Figures 1-4 , a cleaning device for the inner and outer walls of a semi-finished cryogenic pressure vessel, including an ultrasonic cleaning tank 1. Above the ultrasonic cleaning tank 1, there is a rotary conveying screw 2. On one side of the ultrasonic cleaning tank 1, there is a rotary driving structure that can drive the rotary conveying screw 2 to rotate and a lifting driving structure for overall lifting adjustment of the rotary conveying screw 2 and the rotary driving structure. On the other side of the ultrasonic cleaning tank 1, there is a loading and unloading structure that can rotate itself. Further, a spiral conveying surface is provided on the rotary conveying screw 2, which is convenient for increasing the friction force with the long tube part in the semi-finished cryogenic pressure vessel and ensuring that it drives the spiral rotation.

[0024] Specifically, the rotary driving structure includes a lifting slide base 7. One end of the rotary conveying screw 2 is rotatably connected to the lifting slide base 7. A rotary motor 8 for driving the rotary conveying screw 2 to rotate is fixedly installed on the lifting slide base 7. Starting the rotary motor 8 facilitates driving the rotary conveying screw 2 to rotate. Due to the setting of the rotary conveying screw 2, when the long tube part in the semi-finished cryogenic pressure vessel is sleeved on it, when the rotary conveying screw 2 rotates, it drives the long tube part in the semi-finished cryogenic pressure vessel to be conveyed to the side away from the rotary driving structure.

[0025] Specifically, the lifting driving structure includes a support column 6. The lifting slide base 7 slides vertically on the top of the support column 6. A lifting driving cylinder 9 for driving the lifting slide base 7 to lift is fixedly installed on the support column 6. Starting the lifting driving cylinder 9 facilitates driving the lifting slide base 7 to perform lifting adjustment on the support column 6, and further drives the rotary conveying screw 2 and the rotary driving structure to perform overall lifting adjustment.

[0026] Specifically, the loading and unloading structure includes a turning table 3, and a vertical plate 10 is rotatably connected to the top of the turning table 3. Two horizontally distributed support rods 4 with adjustable spacing are arranged on one side of the vertical plate 10. The support rods 4 are also provided with a horizontal feed drive mechanism that drives the two support rods 4 to feed horizontally. The two support rods 4 are convenient for supporting the long tube part of the semi-finished product of the cryogenic pressure vessel from the inside. Through the horizontal feed drive mechanism, it is convenient to send the two support rods 4 and the long tube part of the semi-finished product of the cryogenic pressure vessel supported from the inside to the rotating conveying screw 2, so that the long tube part of the semi-finished product of the cryogenic pressure vessel is sleeved on the side of the rotating conveying screw 2 close to the rotating drive structure, and then Finally, the two support rods 4 are moved toward the middle so that the long tube portion of the semi-finished cryogenic pressure vessel is horizontally placed on the rotating conveying screw 2, and then the two support rods 4 are pulled out from the inside of the long tube portion of the semi-finished cryogenic pressure vessel through the horizontal feed drive mechanism, thus completing the loading. During unloading, as it moves from the rotating conveying screw 2 to the side away from the rotating drive structure, the long tube portion of the semi-finished cryogenic pressure vessel is re-sent onto the two support rods 4. When it is completely separated from the rotating conveying screw 2, the vertical plate 10 can be rotated so that the two support rods 4 can be rotated out from the side aligned with the rotating conveying screw 2, and then the long tube portion of the semi-finished cryogenic pressure vessel can be removed.

[0027] Specifically, it also includes an adjustment frame 11 supporting the two support rods 4, the adjustment frame 11 is threadedly connected with a bidirectional screw 12, and the two sides of the bidirectional screw 12 are symmetrically threadedly connected with adjustment sliders 13 that slide and cooperate with the adjustment frame 11 for guiding. The two support rods 4 are rotatably connected to the two bidirectional screws 12 respectively. The adjustment frame 11 also includes a pitch-adjusting motor 14 that drives the bidirectional screws 12 to rotate. When the pitch-adjusting motor 14 is started, the output shaft of the pitch-adjusting motor 14 rotates clockwise or counterclockwise, which is convenient for driving the bidirectional screw 12 to rotate clockwise or counterclockwise, thereby driving the two adjusting sliders 13 to move to both sides or to the middle, thereby adjusting the distance between the two support rods 4.

[0028] Specifically, the horizontal feed drive mechanism includes a screw sleeve 15 that rotates and penetrates the vertical plate 10, and a feed screw 5 is threadedly connected to the screw sleeve 15. One end of the feed screw 5 is rotatably connected to the adjusting frame 11, and also includes a guide rod 16 that horizontally slides with the vertical plate 10 and is fixedly connected to the adjusting frame 11. A feed drive motor 17 is also provided on the vertical plate 10. The feed drive motor 17 is connected to the screw sleeve 15 through a transmission assembly 18. When the feed drive motor 17 is started, the output shaft of the feed drive motor 17 rotates clockwise or counterclockwise. Through the transmission cooperation of the transmission assembly 18, it is convenient to drive the screw sleeve 15 to rotate clockwise or counterclockwise, thereby driving the feed screw 5 to move left or right, and then conveniently driving the two support rods 4 to perform feeding movement. Furthermore, the transmission assembly 18 can be set to a transmission method of a belt pulley or a sprocket chain.

[0029] Specifically, a steering motor 19 for driving the vertical plate 10 to rotate is fixedly installed at the bottom of the turntable 3. Starting the steering motor 19 causes the output shaft of the steering motor 19 to rotate clockwise or counterclockwise, facilitating the driving of the vertical plate 10 to rotate clockwise or counterclockwise, thereby facilitating the steering operation for loading and unloading.
