Description

Technical Field

[0001] This utility model relates to the technical field of chlorosulfonic acid, and in particular to a chlorosulfonic acid metering tank. Background Technology

[0002] Chlorosulfonic acid is an important inorganic compound with the chemical formula HSO3Cl. At room temperature, it is typically a colorless or pale yellow liquid with a strong, pungent odor. A strong acid, even stronger than sulfuric acid, chlorosulfonic acid is highly corrosive and reacts violently with many metals and organic compounds. Industrially, chlorosulfonic acid has wide applications. It is a key raw material for manufacturing sulfonamide drugs, saccharin, and other fine chemicals, playing an indispensable role in the pharmaceutical and food additive fields. Furthermore, it is used in dye synthesis, participating in the construction of various dye molecules and imparting specific colors and properties to dyes. In organic synthesis reactions, chlorosulfonic acid is often used as a sulfonating agent. Through sulfonation, sulfonic acid groups can be introduced, thereby altering the properties of organic compounds, such as improving their water solubility and stability. The chlorosulfonic acid metering tank, equipped with a heating and stirring mechanism, lays the foundation for subsequent chemical transformations and product development, playing a vital role in the development of the chemical industry. Heating effectively prevents chlorosulfonic acid from solidifying or increasing in viscosity due to low temperatures, ensuring its smooth flow within the metering tank. This guarantees the accuracy and continuity of metering, allowing for precise control of the dosage and facilitating stable operation of subsequent production processes. Stirring ensures a uniform concentration of the chlorosulfonic acid solution, preventing instability in the reaction or fluctuations in product quality due to localized concentration differences. Simultaneously, stirring promotes uniform heat distribution, further enhancing the heating effect, reducing energy consumption and heating time. This mechanism also prevents impurities from accumulating in the tank, reducing the risk of pipe blockage and equipment damage, extending the service life of the metering tank, and reducing maintenance costs. Therefore, chlorosulfonic acid metering tanks are particularly necessary.

[0003] However, when existing chlorosulfonic acid metering tanks are in use, chlorosulfonic acid is prone to solidification at low temperatures. Without a heating mechanism, it will cause it to clump inside the metering tank, block the pipes, hinder the normal transport of materials, and lead to inaccurate metering. Utility Model Content

[0004] The purpose of this invention is to provide a chlorosulfonic acid metering tank to solve the problem mentioned in the background art: when using existing chlorosulfonic acid metering tanks, chlorosulfonic acid is prone to solidification at low temperatures. Without a heating mechanism, it will cause clumps to form in the metering tank, block the pipes, hinder the normal transport of materials, and lead to inaccurate metering.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chlorosulfonic acid metering tank, including a metering tank, a discharge pipe and a placement rack, wherein the discharge pipe is connected to the lower surface of the metering tank, the placement rack is installed on the outer side of the metering tank, a stirring mechanism is provided on the inner side of the metering tank, and a connecting mechanism is provided on the upper surface of the metering tank.

[0006] The stirring mechanism includes a fixed frame, a motor, a connecting rod, a stirring blade, and a heating tube. The fixed frame is installed on the upper surface of the metering tank, the motor is connected to the upper surface of the fixed frame, the connecting rod is connected to one side surface of the motor, the stirring blade is connected to the outer surface of the connecting rod, and the heating tube is installed on the inner surface of the stirring blade.

[0007] Preferably, the connecting rod passes through the metering tank and the fixing frame for connection.

[0008] Preferably, the stirring blades are provided in three sets and are symmetrically distributed.

[0009] Preferably, the connecting mechanism includes a first connecting pipe, a fixing ring, a rubber ring, a connecting ring, a second connecting pipe, and a sealing pipe. The first connecting pipe is threaded onto the upper surface of the metering tank. The fixing ring is fixedly connected to the inner surface of the first connecting pipe. The rubber ring is attached to one side surface of the fixing ring. The connecting ring is installed on the outer surface of the first connecting pipe. The second connecting pipe is provided on one side surface of the first connecting pipe. The sealing pipe is provided on the inner surface of the second connecting pipe.

[0010] Preferably, both the first connecting pipe and the second connecting pipe are fixedly connected to the outer side with a connecting ring, and both the first connecting pipe and the second connecting pipe are installed with a fixing ring and a rubber ring on the inner side.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This chlorosulfonic acid metering tank achieves a good seal by aligning the second connecting pipe with the first connecting pipe and utilizing the cooperation of the sealing pipe, rubber ring, and fixing ring under the action of compression. Then, the connecting ring is fixed with bolts, and the pipeline connection can be easily completed. This connection method is simple to operate, has a good sealing effect, and can effectively prevent chlorosulfonic acid leakage, ensuring the safety of the working environment. When chlorosulfonic acid enters the metering tank, the motor drives the connecting rod to rotate, which in turn causes the stirring blade to stir it. At the same time, the heating tube is activated to heat it. Stirring can make the chlorosulfonic acid mixed evenly, avoiding local concentration differences or precipitation, ensuring the accuracy of metering, and keeping the composition and concentration of chlorosulfonic acid used each time stable and consistent. This is beneficial for the precise control of subsequent chemical reactions or production processes. The heating function can adjust the temperature of chlorosulfonic acid according to process requirements to keep it in a suitable reaction state. Attached Figure Description
