[0002] O-aminophenol is a white needle-shaped crystal with a melting point of 171-176°C. It is soluble in water, ether or ethanol, etc. It is an important chemical intermediate and is widely used in dyes, medicine, printing industry and biological fields. At present, my country's dyes, medicines and other industries have reached a considerable scale, and the corresponding synthetic dyes and pharmaceutical intermediates industries have also developed rapidly. The rational use of these raw materials and intermediates is of great significance for the development and application of various special and high-end products. In the production process of o-aminophenol, the raw materials need to be hydrolyzed. However, in the prior art, precipitation is easily generated in the metering tank during the production of o-aminophenol raw materials, and it is inconvenient to clean, which delays the production efficiency of o-aminophenol.

[0040] The utility model is further described in conjunction with the following embodiments.

[0041] Example 1.

[0042] like Figure 1-3 As shown, a metering tank for producing o-nitrophenol which is easy to clean comprises a metering tank body 1, a tank cover 2 is installed on the top of the metering tank body 1, a rotating mechanism 3 is installed through the tank cover 2, and water supply mechanisms 4 are installed at both ends of the top of the tank cover 2, and a rotating cleaning mechanism 5 is arranged at the inner end of the rotating mechanism 3 extending into the metering tank body 1.

[0043] The water supply mechanism 4 arranged on the tank cover 2 of the metering tank body 1 can transport external cleaning water to the inside of the metering tank body 1. At the same time, the rotating mechanism 3 drives the rotating cleaning mechanism 5 arranged inside the metering tank body 1. The rotating cleaning mechanism 5 rotates and cooperates with the cleaning water to clean the inside of the metering tank body 1.
