Description

TECHNICAL FIELD

[0001] The utility model relates to the field of chemical safety technology, especially to a static electricity elimination equipment. BACKGROUND

[0002] Static discharge can produce thousands of volts or even tens of thousands of volts of voltage in an instant, and this energy is enough to ignite or detonate the combustible gas or dust mixture existing in the chemical laboratory, causing fire or explosion. Therefore, the chemical experiment table will be equipped with relevant static electricity elimination equipment, such as ion fan, which is composed of high-voltage power generator and discharge electrode. The ion fan ionizes air into a large number of positive and negative ions through high-voltage corona discharge at the tip, and then blows a large number of positive and negative ions to the surface of the object to neutralize static electricity, or directly puts the static electricity eliminator close to the surface of the object to neutralize static electricity.

[0003] For example, Chinese utility model patent (CN222381842U) discloses a chemical safety static electricity elimination equipment, which records: "by aligning the three protrusions on the mesh cover and pressing them into the grooves of the mounting ring, the locking assembly extrudes the protrusions of the mesh cover to fix the mesh cover on the mounting ring. The mesh cover can be installed on the ion fan body at one time. Turn the rotating ring to drive the locking assembly away from the protrusions of the mesh cover to release the locking of the mesh cover and the mounting ring. Take out the three protrusions on the mesh cover from the grooves of the mounting ring. The mesh cover can be disassembled from the ion fan body at one time. Compared with the existing technology, the mesh cover needs to be tightened with multiple screws during maintenance, which improves the work efficiency of installing or disassembling the mesh cover.", and also records: "because the high-voltage electrode needle of the ion fan is exposed to the air, it will generate a high-voltage electric field, so dust will be attracted to the electrode needle and the mesh cover of the ion fan, which needs to be cleaned and maintained regularly to restore the electricity elimination performance. The traditional ion fan mesh cover is generally fixed and connected to the fan shell with multiple screws. When disassembling the mesh cover for maintenance, multiple screws need to be unscrewed, which is relatively cumbersome and inconvenient to maintain."

[0004] In summary, the existing technology uses ion fan body for static electricity elimination in chemical safety, but this method has the following technical problems: the above-mentioned device can only eliminate static electricity in one direction, the area of static electricity elimination is limited, and the practicability of the device is low. Therefore, the present application proposes a static electricity elimination equipment to solve the technical problems mentioned in the above-mentioned patent and provides a new technical solution.
