[0002] Electronic chemical storage tanks are widely used in industrial production to store a variety of electronic chemicals, such as acids, bases, and solvents. These chemicals are often corrosive, flammable, and explosive, making the safety of these tanks crucial. Purity is another key characteristic of electronic chemicals, and storage must prevent contamination from external impurities. During storage and transportation, tanks may experience internal pressure fluctuations, necessitating pressure relief through pressure relief vents to prevent rupture, deformation, and product contamination.

[0003] However, existing electronic chemical storage tank designs often overlook the issue of protecting the pressure relief vent. Directly exposed to the external environment, the vent is susceptible to blockage, corrosion, or mechanical damage. This not only affects the proper function of the pressure relief function but can also lead to chemical leakage, causing environmental pollution and safety hazards, and contaminating the product within the tank. In light of this, the present utility model proposes a pressure relief vent protection device for electronic chemical storage tanks to address these issues. Utility Model Content

The outer wall thread of the connecting screw 41 is sleeved with a connecting nut 21, and the connecting nut 21 descends axially along the connecting screw 41 and contacts the protective cover 20, pressing the protective cover 20 against the surface of the storage tank 10.

[0036] In this embodiment, when protecting the pressure relief pipe 11, the cover plate 40 is connected to the pressure relief pipe 11 to block the pressure relief pipe 11, and then the protective cover 20 is sleeved on the outside of the pressure relief pipe 11, and the connecting nut 21 is sleeved on the outer wall of the connecting screw 41, and the connecting nut 21 is continuously rotated so that the connecting nut 21 descends along the axial direction of the connecting screw 41 until the connecting nut 21 contacts the protective cover 20, and the protective cover 20 is pressed against the storage tank 10 so that the protective cover 20 is in close contact with the storage tank 10, thereby isolating the pressure relief pipe 11 from the outside;

[0037] By arranging the cover plate 40 and the protective cover 20 on the storage tank 10, the pressure relief pipe 11 can be effectively blocked to prevent the external environment from affecting the pressure relief pipe 11. Through the matching design of the connecting screw 41 and the connecting nut 21, the protective cover 20 can be tightly pressed against the surface of the storage tank 10, thereby achieving effective protection of the pressure relief pipe 11 and preventing chemical leakage or other safety hazards caused by damage to the pressure relief pipe 11. The structural design of the device is simple and the installation is convenient. It can improve the safety and reliability of the storage tank 10 and has significant practical value.

[0038] By providing a cover 40 and a protective cover 20 on the storage tank 10, the pressure relief pipe 11 can be effectively isolated from the outside. When the pressure relief pipe 11 is undergoing pressure relief treatment, impurities in the external environment can be effectively prevented from entering the pressure relief pipe 11, thereby effectively preventing impurities in the external environment from entering the storage tank 10 and causing pollution to electronic chemicals.

[0040] The pressure relief flange 14 is evenly provided with a plurality of pressure relief mounting holes 13, and the cover plate 40 is evenly provided with a plurality of cover plate mounting holes 44. The positions of the plurality of pressure relief mounting holes 13 and the plurality of cover plate mounting holes 44 are matched, and the pressure relief mounting holes 13 and the cover plate mounting holes 44 are connected by bolts.

[0041] In this embodiment, the cooperation between the pressure relief mounting hole 13 and the cover plate mounting hole 44 can facilitate the connection of the cover plate 40 to the pressure relief pipe 11 so as to seal the pressure relief pipe 11 .

[0044] In this embodiment, when the protective cover 20 is brought into close contact with the storage tank 10, the connecting nut 21 and the connecting washer 22 are sleeved on the outer wall of the connecting screw 41, and then the connecting nut 21 is rotated. Through the threaded engagement of the connecting nut 21 and the connecting screw 41, the connecting washer 22 is lowered and contacts the protective cover 20 until the protective cover 20 contacts the surface of the storage tank 10 after being lowered.

[0045] Specifically, the protective cover 20 is made of transparent PVC material, and a plurality of exhaust holes 23 are opened on the surface of the protective cover 20. The exhaust holes 23 are evenly arranged on the protective cover 20.

[0046] A rubber ring 24 is provided at the bottom end of the protective cover 20 . The rubber ring 24 is fixedly connected to the protective cover 20 and contacts the surface of the storage tank 10 .

[0048] When the pressure relief pipe 11 is subjected to pressure relief processing, the mounting bolts 12 are loosened to create a gap between the cover plate 40 and the pressure relief flange 14 , and then the pressure relief processing is performed through the exhaust hole 23 .

[0049] Specifically, the clamping assembly 50 includes multiple groups of counterweight clamping plates 51, each of which is provided with a clamping hole 54, in which the connecting screw 41 is disposed.

Since the exhaust hole 23 is opened on the protective cover 20, the inert gas is continuously introduced into the protective cover 20, thereby forming a gas shielding layer at the pressure relief pipe 11. When the pressure relief pipe 11 is subjected to pressure relief treatment, impurities can be effectively prevented from entering the interior of the pressure relief pipe 11.

[0055] Specifically, the cover plate 40 is provided with multiple groups of support blocks 45 , which are arranged in a ring array on the cover plate 40 . The support blocks 45 match the positions of the air supply holes 43 , and the counterweight pressing plates 51 are provided on the multiple groups of support blocks 45 .

[0056] In this embodiment, the supporting block 45 can be provided to elevate the counterweight pressing plate 51 , so that the air supply hole 43 can facilitate the inert gas to be introduced into the interior of the protective cover 20 .
