[0002] Sulfuric acid is an important chemical raw material. It is highly corrosive and oxidizing. Therefore, sulfuric acid plants are equipped with sulfuric acid storage tanks to store the produced sulfuric acid.

[0003] For example, the utility model patent with patent application number 202220893192.3 and name of a corrosion-resistant sulfuric acid storage tank discloses a corrosion-resistant sulfuric acid storage tank, including a tank body and an upper cover. The upper cover is installed on the upper end of the tank body, and the upper cover and the tank body are fixedly installed by multiple locking parts. There are multiple protective structures evenly distributed on the outside of the tank body. The tank body includes a shell, a corrosion-resistant layer one and an anti-corrosion coating layer. The shell is arranged at the outermost side of the tank body, and the inner side of the shell is provided with a corrosion-resistant layer one. The inner wall of the corrosion-resistant layer one is coated with an anti-corrosion coating layer; the upper cover includes a top cover, and a corrosion-resistant layer two is provided at the bottom of the top cover, and a sealing plug is provided in the middle of the lower end of the corrosion-resistant layer. The corrosion-resistant layer two and the corrosion-resistant layer one are both made of high-silicon cast iron or high-alloy stainless steel, and the outer side of the sealing plug is coated with an anti-corrosion coating. In the utility model, by providing a corrosion-resistant layer one and an anti-corrosion coating layer in the tank body and a corrosion-resistant layer two in the upper cover, the corrosion resistance of the storage tank can be improved and its service life can be increased.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0022] Embodiment 1:

[0023] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 A sulfuric acid storage tank comprises a storage box 1 and a box cover 104 detachably connected to the storage box 1, and also comprises: a connecting block 3, symmetrically fixedly connected to both sides of the storage box 1, wherein a connecting groove 301 is provided on the connecting block 3, a plug-in block 302 used in conjunction with the connecting groove 301 is fixedly connected to the box cover 104, and a groove 303 is provided on the side wall of the plug-in block 302; a clamping block 304, slidably connected in the groove 303; a spring 305, arranged in the groove 303, and one end of the spring 305 is fixedly connected to the clamping block 304, and the other end is fixedly connected to the inner wall of the groove 303, wherein the plug-in block 302 is plugged into the connecting groove 301, and the clamping block 304 is clamped on the lower surface of the connecting block 3; a pulling and retracting assembly, arranged on the box cover 104, and used by the staff to retract the clamping block 304 into the groove 303 by pulling and retracting the assembly.

[0024] The connection mode between the box cover 104 and the storage box 1 is as follows:

[0025] When in use, the box cover 104 is closed on the storage box 1, so as to achieve a closed and sealed storage box 1. At the same time, during the closing process, the box cover 104 is plugged into the connecting groove 301 through the plug-in block 302, so that the clamping block 304 is squeezed by the groove wall of the connecting groove 301 and retracts into the groove 303, and compresses the spring 305. Then, when the box cover 104 is in contact with the storage box 1, the groove 303 on the side wall of the plug-in block 302 moves out of the connecting groove 301, and the compressed spring 305 generates a thrust, pushing the clamping block 304 to move out of the groove 303 and clamped on the lower surface of the connecting block 3, thereby achieving the limit fixation of the box cover 104, so that the box cover 104 and the storage box 1 can be connected more conveniently.

[0026] Embodiment 2:

[0027] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 , a sulfuric acid storage tank, is basically the same as Example 1, and further, the pulling and retracting assembly includes a guide component and a lifting block 402 slidably connected to the guide component; it also includes a guide sleeve 403 fixedly connected to the box cover 104, wherein a pull rope 404 is provided in the guide sleeve 403, one end of the pull rope 404 is fixedly connected to the lifting block 402, and the other end passes through the box cover 104, the plug-in block 302 and the clamping block 304 are fixedly connected.

[0028] The guide component includes a guide rod 4 symmetrically fixedly connected to the box cover 104 , the upper end of the guide rod 4 is fixedly connected to a limit block 401 , and the lifting block 402 is slidably connected to the guide rod 4 .

[0029] When it is necessary to disassemble the box cover 104, the staff can push the lifting block 402 to move upward under the limit guidance of the guide rod 4. At the same time, when the lifting block 402 moves upward, the pull rope 404 can pull the clamping block 304 back into the groove 303 and compress the spring 305 until the clamping block 304 is completely retracted into the groove 303, thereby releasing the limit fixation of the box cover 104, and then the box cover 104 can be removed from the storage box 1 through the lifting block 402, so that the box cover 104 can be disassembled more conveniently to facilitate the storage and access of sulfuric acid.

[0030] Embodiment 3:

[0031] Reference Figure 2 , a sulfuric acid storage tank, which is basically the same as Example 1, and further, an anti-corrosion layer 102 is fixedly installed on the inner wall of the storage tank 1, and an anti-corrosion coating 103 is applied on the anti-corrosion layer 102.

[0032] When sulfuric acid is stored in the sulfuric acid storage tank, the anti-corrosion layer 102 and the anti-corrosion coating 103 are provided, so that the storage box 1 can be well protected from corrosion, thereby extending the service life of the storage box 1 and preventing impurities generated by corrosion of the storage box 1 from affecting the chemical properties of sulfuric acid.

[0033] A vacuum chamber 101 is provided between the inner and outer walls of the storage box 1; the vacuum chamber 101 can be well insulated from external heat to prevent external heat from being conducted into the storage box 1 and causing sulfuric acid to volatilize due to heat, thereby improving the preservation effect of sulfuric acid.

[0034] Embodiment 4:
