Description

Technical Field

[0001] The invention relates to the technical field of pickling and degreasing of pressure vessels, in particular to a device for pickling and degreasing the surface of a finished pressure vessel. Background Art

[0002] Pressure vessels are widely used in numerous industries, including petroleum, chemical, power, and pharmaceuticals, making their safety paramount. During the manufacturing process, the cleanliness of the finished pressure vessel surface directly impacts its corrosion resistance, service life, and overall performance. Impurities such as oil, grease, rust, and scale may remain on the surface. If not thoroughly removed, these impurities can cause corrosion and other problems during subsequent use, reducing the safety and reliability of the vessel. Therefore, an acid-washing and degreasing device is required to clean the surface dirt of pressure vessels.

[0003] When using the existing pressure vessel finished surface pickling and degreasing device, the pressure vessel is usually immersed in the pickling liquid and degreasing liquid for cleaning, thereby removing the dirt on the surface of the pressure vessel cost, thereby ensuring the safety and reliability of the pressure vessel in subsequent use.

[0004] However, the existing surface pickling and degreasing device for finished pressure vessels has the following shortcomings:

[0005] 1) The existing device for pickling and degreasing the surface of finished pressure vessels cannot clamp pressure vessels of different sizes. It is necessary to manually carry the pressure vessels and place them in the pickling solution or degreasing solution. The overall operation is relatively cumbersome and easily causes harm to the workers' health, making it difficult to meet actual use needs.

[0006] 2) The existing device for pickling and degreasing the surface of finished pressure vessels cannot ensure that the pressure vessels are fully cleaned. The container needs to be moved during the cleaning process to ensure that it is fully in contact with the pickling liquid and degreasing liquid.

Through the setting of the stirring and toggling mechanism 15, when cleaning the surface of the finished pressure vessel, the clean water, pickling liquid and degreasing liquid can always be in a flowing state, thereby making them fully contact with the finished pressure vessel, further improving the cleaning effect and reducing the difficulty of cleaning. Among them, the stirring shaft 1501 passes through the position of the water washing tank 7 and adopts a sealing design to effectively prevent the clean water, pickling liquid and degreasing liquid from flowing out.

[0041] according to Figure 1 and Figure 2As shown, the adjustable telescopic mechanism 4 includes a U-shaped frame 401, which is fixedly mounted on the top of the top plate 3, and a first servo motor 402 is installed at one end of the U-shaped frame 401, and the output end of the first servo motor 402 is movable through the U-shaped frame 401 and is connected to a first screw rod 403, and a first sliding frame 404 is provided on the outside of the first screw rod 403, and a servo cylinder 405 is installed on the inside of the first sliding frame 404, and the output end of the servo cylinder 405 is connected to the connecting plate 501.

[0042] according to Figure 1 、 Figure 2 and Figure 7 As shown, the air-drying mechanism 16 includes a fan 1601, which is fixedly installed on the top of the top plate 3. A dustproof net 1602 is installed at the input end of the fan 1601, and an air collecting hood 1603 is installed at the output end of the fan 1601.

A plurality of nozzles 1606 are evenly distributed on the outer wall of the diversion pipe 1605, and the diversion pipe 1605 is installed between the two brackets 2. Through the setting of the air-drying mechanism 16, the finished pressure vessel can be quickly dried after the finished pressure vessel is cleaned, thereby improving the overall work efficiency.

[0043] according to Figure 1 、 Figure 2 and Figure 8 As shown, the limiting support mechanism 17 includes a fixed seat 1701, which is fixedly installed on the top of the workbench 1 by bolts, and a fixing rod 1702 is installed on the inner side of the fixed seat 1701. Two sliding blocks 1703 are slidably installed on the outer side of the fixing rod 1702, and two springs 1704 are sleeved on the outer side of the fixing rod 1702.

Through the setting of the mounting bracket 10 and the electric heating plate 11, the clean water, pickling liquid and degreasing liquid can be heated, thereby improving the cleaning effect.

[0045] according to Figure 1 、 Figure 2 and Figure 3 As shown, solenoid valves 12 are installed at the bottom of the water washing tank 7, the degreasing tank 8 and the pickling tank 9. The bottom of each solenoid valve 12 is connected to a drain pipe 13.

[0046] according to Figure 3 As shown, a partition net 14 is installed inside the water washing tank 7, the degreasing tank 8 and the pickling tank 9. Each partition net 14 is arranged above a corresponding stirring and toggling mechanism 15. Through the arrangement of the partition net 14, the finished pressure vessel can be blocked during the cleaning process to prevent it from coming into contact with the stirring and toggling mechanism 15, thereby improving the safety of the device during use.

[0047] according to Figure 1 and Figure 2 As shown, tripods 18 are installed at the four corners of the bottom of the workbench 1, and an anti-slip pad 19 is fixedly installed at the bottom of each tripod 18. Through the setting of the tripod 18, it is possible to provide more stable support for the workbench 1. At the same time, in conjunction with the anti-slip pad 19, the friction with the ground is increased, thereby improving the stability of the device during use.

[0048] Working principle: First, move the device to the designated location, and connect the circuit to the electrical equipment in the device in sequence to ensure that the device can operate normally.

[0049] During the preparation stage, clean water is added to the water washing tank 7, degreasing liquid is added to the degreasing tank 8, and acid is added to the pickling tank 9, and the corresponding electric heating plates 11 are started to heat the three. Then, the finished pressure vessel to be cleaned is placed on the corresponding two limit support mechanisms 17. At this time, under the action of gravity, the sliding block 1703 slides on the fixed rod 1702, and the spring 1704 contracts under the extrusion force. At this time, the two anti-slip frames 1705 clamp the outside of the finished pressure vessel to be cleaned to fix it.

[0050] During the clamping and conveying stage, first, the first servo motor 402 is started to drive the first screw rod 403 to rotate, prompting the first sliding frame 404 to slide, driving the multi-directional clamping mechanism 5 to move above the finished pressure vessel to be cleaned, and then the servo cylinder 405 pushes the multi-directional clamping mechanism 5 down to the top of the finished pressure vessel to be cleaned, and then the second servo motor 508 is started to drive the corresponding second screw rod 503 to rotate, so that the first pulley 504 and the first transmission belt 505 cooperate to drive the other second screw rod 503 to rotate, prompting the two sliding plates 506 to slide close to drive the clamping claws 507 to clamp the outer side of the finished pressure vessel to be cleaned. While the second screw rod 503 rotates, the first bevel gear 509 drives the second bevel gear 512 and the third screw rod 511 to rotate, prompting the second sliding frame 513 to drive the adsorption rotation mechanism 6 to clamp the two ends of the finished pressure vessel to be cleaned.

[0051] During the container cleaning stage, the adjusting telescopic mechanism 4 is started again to move the finished pressure vessel clamped by the multi-directional clamping mechanism 5 into the water washing tank 7, and then the servo cylinder 405 pushes it down to immerse it in clean water for preliminary cleaning. Then, when the preliminary cleaning is completed, the adjusting telescopic mechanism 4 drives it to move to the degreasing tank 8, and then the servo cylinder 405 pushes it down to immerse it in the degreasing liquid for degreasing. After the degreasing is completed, the adjusting telescopic mechanism 4 drives it to move to the pickling tank 9, and then the servo cylinder 405 pushes it down to immerse it in the pickling liquid for pickling. During the entire cleaning process, The corresponding fourth servo motor 1505 is started in sequence to drive the corresponding stirring shaft 1501 to rotate, and then the third pulley 1503 and the third transmission belt 1504 cooperate with each other to drive the other stirring shaft 1501 to rotate, so that the stirring blade 1502 stirs the clean water, degreasing liquid or pickling liquid so that it can fully contact the finished pressure vessel. At the same time, the third servo motor 603 is started to drive the second pulley 604 to cooperate with the second transmission belt 605 and the rotating shaft to drive the rotating suction cup 606 to rotate, so that the finished pressure vessel rotates during the cleaning process, thereby improving the cleaning effect.

[0052] During the air-drying and discharging stage, after cleaning is completed, the adjusting telescopic mechanism 4 drives it to move to the two limit supporting mechanisms 17 at the discharging position, and then the servo cylinder 405 pushes it down. At the same time, the multi-directional clamping mechanism 5 releases the clamping, and the cleaned pressure vessel product is placed on the two limit supporting mechanisms 17. Then the fan 1601 is started, and the air flow is transported to the diversion pipe 1605 through the conveying pipe 1604. After it is sprayed out by the nozzle 1606, the pressure vessel product is quickly air-dried.

[0053] By operating according to the above-mentioned contents, the use of the pickling and degreasing device for the surface of the finished pressure vessel can be completed.
