[0002] In traditional tank management, cleaning work does face many challenges. It mainly relies on manual work or the use of simple cleaning tools, which is not only inefficient but also difficult to achieve a comprehensive and thorough cleaning effect. During manual cleaning, workers need to enter the tank to perform operations, which is not only labor-intensive but also poses safety risks, especially when handling harmful or corrosive chemicals. At the same time, simple cleaning tools often cannot reach every corner of the tank, resulting in residual dirt and sediment.

[0003] After storing chemicals for a long time, the dirt and sediment accumulated inside the tank will have a negative impact on the efficiency of the tank. These dirt not only occupy the effective volume of the tank and reduce the storage capacity, but may also affect the quality of the chemicals and even cause chemical reactions or pollution. In addition, the presence of dirt and sediment may also damage the structure and materials of the tank and accelerate its corrosion and aging process; this will not only cause waste of resources and environmental pollution, but may also pose a threat to personnel safety.

[0024] The utility model embodiment provides a corrosion-resistant chemical storage tank, such as Figure 1-6As shown, it includes a tank body 1; a first cleaning mechanism arranged in the tank body 1; and a second cleaning mechanism arranged below the first cleaning mechanism; wherein the first cleaning mechanism includes: a sealing seat 2 arranged on the top side of the tank body 1; a first electric push rod 3 arranged in the sealing seat 2; a connecting plate 4 arranged at the telescopic end of the first electric push rod 3; a cleaning nozzle 5 arranged on the other side of the connecting plate 4; a water inlet 6 arranged at the top of the tank body 1, and the water inlet 6 is connected to the cleaning nozzle 5 through a flexible tube 7; one side of the sealing seat 2 is open, and a group of sealing plates 8 are hingedly matched at the open part; a group of second electric push rods 9 are arranged on the inner side of the sealing seat 2, and the telescopic ends of the two electric push rods are connected to the inner walls of the corresponding sealing plates 8.

[0025] It should be noted that due to the cleaning difficulties in the existing tank body 1 management, manual cleaning is inefficient and difficult to be comprehensive and thorough; at the same time, the operation risk is high, especially when dealing with harmful chemicals. After long-term storage, the dirt in the tank affects the use efficiency and quality of the chemicals, and accelerates corrosion and aging. This solution achieves comprehensive and efficient cleaning of the inside of the tank body 1, and effectively seals the tank body 1 after cleaning to prevent leakage of cleaning liquid or chemicals. This not only avoids pollution from the external environment, but also protects the cleaning mechanism and the tank body 1 itself from damage. At the same time, the sealing property also helps to slow down the corrosion rate of the chemicals in the tank body 1, reduce the risk of chemical residues, and improve storage. and safety during use; in addition, the second cleaning mechanism of the device can cover every corner of the tank body 1 through the coordinated movement of the lateral plate 13 and the connecting rod 12, closely contact the inner wall and remove attached dirt or sediment. This cleaning method is not only comprehensive, but also can reach deep into hard-to-reach areas, ensuring thorough cleaning of the inside of the tank body 1. Finally, the device also adopts a multi-level structural design. From the inner lining layer 15 to the outer protective layer 18, each layer has specific functions and advantages, which together ensure the excellent corrosion resistance and physical protection performance of the tank body 1. This design enables the tank body 1 to operate stably in various harsh environments, reducing maintenance costs and usage risks.

[0026] Specifically, in this embodiment, the scheme mainly includes a tank body 1; a sealing seat 2 is installed on the inner top side of the tank body 1 to provide support for the first cleaning mechanism. When cleaning is required, the first electric push rod 3 extends to push the connecting plate 4 and the cleaning nozzle 5 thereon to move downward until the cleaning nozzle 5 can cover the area inside the tank body 1 that needs to be cleaned. The cleaning nozzle 5 is connected to the water inlet 6 on the top of the tank body 1 through the flexible tube 7. When the cleaning program is started, the cleaning liquid flows in from the water inlet 6, passes through the flexible tube 7, and finally sprays out from the cleaning nozzle 5. This design allows the cleaning liquid to evenly cover every corner inside the tank body 1, thereby effectively removing chemical residues and dirt;

[0027] One side of the sealing seat 2 is designed to be open and is equipped with a sealing plate 8. The sealing plate 8 can be opened and closed by hinged cooperation. During the cleaning process, the second electric push rod 9 is responsible for controlling the opening and closing of the sealing plate 8. When the cleaning nozzle 5 needs to work, the second electric push rod 9 drives the sealing plate 8 to open, allowing the cleaning nozzle 5 to extend into the tank body 1 for cleaning. When the cleaning is completed, the second electric push rod 9 drives the sealing plate 8 to close again to maintain the sealing of the tank body 1.

[0028] This sealing design is very important. It not only prevents cleaning liquid or chemicals from leaking to the outside of the tank body 1, but also avoids damage to the first cleaning mechanism during subsequent processing. In addition, maintaining the sealing of the tank body 1 also helps prevent oxygen and moisture in the external air from entering the tank body 1, further slowing down the corrosion rate of the chemicals.

[0029] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the second cleaning mechanism includes: a rotating shaft 11 rotating in the tank body 1 ; a connecting rod 12 arranged outside the rotating shaft 11 ; and a lateral plate 13 arranged outside the connecting rod 12 .

[0030] In this embodiment, when the rotating shaft 11 starts to rotate, it will drive the connecting rod 12 to move together. The side plate 13 on the outside of the connecting rod 12 will move in the tank body 1 along with the movement of the connecting rod 12. During the cleaning process, the side plate 13 will contact the inside of the tank body 1 to remove dirt or sediment on the inner wall of the tank body 1 during the movement.

[0031] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the second cleaning mechanism further includes: a servo motor 14 disposed on the top of the tank body 1 , and an output end of the servo motor 14 is fixedly connected to an end key of the rotating shaft 11 .

[0032] In this embodiment, by controlling the output of the servo motor 14 , the rotation speed and the rotation angle of the rotating shaft 11 can be precisely controlled, thereby precisely controlling the movement trajectory and speed of the connecting rod 12 and the side plate 13 .

[0033] In a further preferred embodiment of the present invention, Figure 5 As shown, the tank body 1 is provided with an inner lining layer 15, a secondary inner layer 16, a structural layer 17 and an outer protective layer 18 in sequence from the inside to the outside.

[0034] In this embodiment, the inner lining layer 15 is composed of glass fiber surface felt and lining resin, which mainly plays the role of anti-seepage and anti-corrosion, and has good air tightness and high smoothness. The sub-inner layer 16 is reinforced with lining resin and alkali-free glass fiber spray yarn. In addition to corrosion resistance, it also protects the inner lining layer 15 to prevent its crack extension. The structural layer 17 is formed by winding the alkali-free untwisted glass fiber winding yarn impregnated with structural resin and then wound in a combination of circumferential and cross directions. The outer protective layer 18 is the outermost protective structure to prevent the external environment from eroding the structure of the tank body 1 and resist physical damage.
