[0002] Chemical storage tanks, also known as chemical storage vessels or chemical storage containers, are tanks used in the chemical industry to store chemical raw materials, such as acids, alkalis, alcohols, gases, and liquids. The sealing cap at the top of the chemical storage tank is a key component used to prevent leakage of fluids or solid particles from the top of the tank, and to prevent external impurities (such as dust and moisture) from entering the tank's interior. This device plays a vital role in the chemical industry because it directly affects the safety of the stored media, environmental protection, and production efficiency.

[0003] Existing chemical storage tank sealing cover devices are usually complex to install, increasing the time required for manual and mechanical work and increasing installation costs. In addition, the sealing cover uses sealing rings for sealing, but the sealing effect of the sealing rings is poor and cannot effectively prevent the leakage of chemicals from the tank.

[0017] The technical solution of this utility model will be clearly and thoroughly described below with reference to specific embodiments: like Figures 1-3 The device shown is a sealing cover for quick opening of the top of a chemical storage tank, comprising a tank body 1, with multiple fixed plates 12 uniformly and fixedly connected in a ring on the top surface of the tank body 1, a rotating plate 13 movably disposed on the top of the fixed plates 12, and a top cover 2 rotatably disposed on the top of the tank body 1. Multiple screw rods 3 are arranged in a ring on the top surface of the top cover 2, and a snap-fit ​​plate 31 is fixedly connected to the top of the screw rods 3, snapping the rotating plate 13. The tank body 1 is usually used to store various chemicals. In order to prevent chemical leakage and cause safety accidents, the top cover 2 is required to seal the tank body 1 for storage.

[0018] A fixing block 11 is fixedly connected to one side of the top surface of the tank body 1, and a connecting plate 21 is fixedly connected to the outer periphery of the top cover 2. The connecting plate 21 is rotatably connected to the fixing block 11. When the top cover 2 rotates, it drives the connecting plate 21 to rotate on the fixing block 11, which facilitates the installation of the tank body 1 and the top cover 2.

[0019] A rotating rod 34 is rotatably mounted in the middle of the top cover 2. The end of the rotating rod 34 passes through the top cover 2 and is fixedly connected to the second gear 33. A handle 36 is fixedly connected to the top of the rotating rod 34. Rotating the handle 36 causes the rotating rod 34 to rotate.

[0020] It should be noted that the top cover 2 is provided with multiple first gears 32 and a second gear 33, and the second gear 33 is meshed with the first gear 32; the rotating rod 34 rotates to drive the multiple first gears 32 to rotate.

[0021] It should also be noted that the top cover 2 has multiple threaded sleeves 35 connected in a ring shape inside. The threaded sleeves 35 are fixedly connected to the first gear 32. The lead screw 3 passes through the top cover 2 and is threadedly connected to the threaded sleeves 35. The rotation of the first gear 32 drives the threaded sleeves 35 to rotate. The rotation of the threaded sleeves 35 drives the lead screw 3 to move up and down. The up and down movement of the lead screw 3 completes the subsequent snap-fit ​​work.

[0022] Furthermore, an annular plate 42 is slidably connected inside the annular groove 4. The bottom surface of the annular plate 42 is fixedly connected to the top surface of the suction cup 41.

The movement of the annular plate 42 drives the suction cup 41 to move, thereby completing the subsequent bonding work between the top cover 2 and the edge ring plate 14.

[0023] When the chemicals are placed inside the tank body 1, rotate the top cover 2 to cover the top surface of the tank body 1. Then rotate the rotating plate 13 until it contacts the top surface of the top cover 2. The opening of the rotating plate 13 engages with the screw 3. Adjust the screw 3 by coordinating the components. The screw 3 moves downward, which in turn moves the locking plate 31. The locking plate 31 engages with the top surface of the top cover 2, thus completing the installation of the tank body 1 and the top cover 2. The installation of the top cover 2 is convenient and quick, reducing the time spent on manual labor and machinery, lowering installation costs, and reducing the potential risk of chemical exposure inside the tank body 1, thus reducing the risk of accidents.

[0024] It should be noted that the rotating plate 13 has an opening that can be inserted into the lead screw 3, which facilitates the subsequent engagement of the snap-fit ​​plate 31 with the rotating plate 13.

[0025] Furthermore, an edge ring plate 14 is fixedly connected to the middle of the tank body 1, and an annular groove 4 is opened on the bottom surface of the top cover 2. A suction cup 41 is slidably arranged inside the annular groove 4, and the bottom surface of the suction cup 41 is in contact with the top surface of the edge ring plate 14. When the top cover 2 is installed, the screw 3 moves downward, which drives the suction cup 41 to move downward at the same time. The suction cup 41 contacts the top surface of the edge ring plate 14, and the suction cup 41 can tightly fit the edge ring plate 14 to form a reliable sealing layer, effectively preventing the leakage of chemicals inside the tank body 1. Thus, the sealing between the tank body 1 and the top cover 2 is completed during the installation of the top cover 2, which simplifies the operation process, reduces the difficulty of operation, and improves work efficiency.

[0026] Furthermore, the suction cup 41 is an annular suction cup; the annular design of the suction cup 41 allows it to adapt to edge ring plates 14 of different shapes and sizes, ensuring a good sealing effect under various conditions. At the same time, the tight fit between the suction cup 41 and the edge ring plate 14 can disperse the pressure on the top of the tank body 1 and enhance the structural stability of the tank body 1.
