Description

Technical Field

[0001] The utility model belongs to the technical field of chlorine buffer tanks, and particularly relates to a filtering device for a chlorine buffer tank. Background Art

[0002] The chlorine buffer tank is a very common container in chemical production. The chlorine buffer tank contains chlorine with great toxicity. It is generally located between the chlorine storage tank and the reactor. In order to prevent impurities in the chlorine from entering the reactor and causing adverse effects, a filtering structure is usually provided inside the chlorine buffer tank, and the chlorine entering the chlorine buffer tank is filtered through the chlorine filtering structure. Although the existing filtering device of the chlorine buffer tank can meet the basic needs of filtering chlorine, the chlorine filtering structure is arranged on the only chlorine entry path, and after a period of work, the filtering structure needs to be disassembled, cleaned and reinstalled because it has intercepted a lot of impurities. Therefore, the chlorine buffer tank cannot continue to store and filter the chlorine normally, which will affect the smooth progress of the entire processing process and bring great inconvenience to people's use.

[0003] For example, the utility model with announcement number CN 220436201 U discloses a chlorine buffer tank with a filtering function. In the technical solution of this patent, the first filter screen and the second filter screen are both arranged on the only entry path of the chlorine. Therefore, after a period of use, when the first filter screen and the second filter screen need to be disassembled and cleaned, the device needs to be suspended. The device can continue to work only after the cleaning is completed and reinstalled, which affects the normal use of the user. Utility Model Content
