Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a multi-component rectification tower for isopropanol production. Background Technique

[0002] Isopropanol, also known as 2-propanol, is an organic compound, an isomer of n-propanol. It is a colorless and transparent liquid with an odor similar to a mixture of ethanol and acetone. It is soluble in water and can also be dissolved in most organic solvents such as alcohols, ethers, benzene, and chloroform. Isopropanol is an important chemical product and raw material, commonly used in fields such as pharmaceuticals, cosmetics, plastics, and coatings. Due to the relatively complex structure of isopropanol during the extraction process, a rectification tower is required to carry out multi-component reactions on the materials to achieve the separation effect.

[0003] During the use of the existing isopropanol rectification tower, usually the liquid phase material and the material are added into the rectification tower, and a heating device is used to heat the tower body to promote the reaction. However, after the material enters the rectification tower, the liquid phase material is in a static state, its chemical components are not active enough, and the reaction with the material is small. Therefore, the extraction efficiency is low. Moreover, the material is easily adhered to the inner wall of the rectification tower after heating. This leads to the difficulty in cleaning the material adhering to the inner wall of the tower during the second use, and it is very easy to occur the situation of corruption and deterioration, and its chemical molecules change, which is likely to affect the entire process of the secondary reaction, and there is a certain room for improvement. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a multi-component rectification tower for isopropanol production.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

Four support legs are fixedly connected to the lower surface of the positioning ring. A liquid inlet pipe is communicated with the surface of the tower body. A heater is fixedly connected to the bottom end of the tower body. A drain pipe is communicated with the bottom end of the tower body. A first solenoid valve is installed on the surface of the drain pipe. A feeding assembly is communicated with the surface of the tower body. The top end of the tower body is fixedly connected with a top cover through mounting bolts. A servo motor is fixedly connected to the upper surface of the top cover. The output end of the servo motor is fixedly connected with a stirring assembly. The stirring assembly includes a round rod. A circular block is fixedly connected to the bottom end of the round rod.

[0007] The feeding assembly includes an inclined pipe. One end of the inclined pipe far from the tower body is fixedly connected with a feeding cylinder. A vertical pipe is communicated with the surface of the feeding cylinder. A second solenoid valve is fixedly connected to the surface of the vertical pipe. The top end of the vertical pipe is communicated with a storage bin. An electric push rod is fixedly connected to the left end of the feeding cylinder. A circular push plate is slidably connected to the inner wall of the feeding cylinder.

[0008] Preferably, a circular clamping groove adapted to the circular block is formed on the inner bottom wall of the tower body. The circular clamping groove can position the round rod to ensure that it will not shift.

[0009] Preferably, the side of the cleaning blade away from the strip plate abuts against the inner wall of the tower body, and the cleaning blade can contact the inner wall of the tower body.

[0010] Preferably, the thickness of the cleaning blade is less than the inner diameters of the liquid inlet pipe and the inclined pipe. When the cleaning blade is located at the positions of the liquid inlet pipe and the inclined pipe, it will not affect the feeding.

[0011] Preferably, a through hole is formed at the top end of the storage bin. A feeding hopper is fixedly connected to the inner wall of the through hole. The material is poured into the storage bin through the feeding hopper to achieve quantitative feeding.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. By setting the servo motor and the round rod, while driving the stirring arm to rotate and improving the reaction efficiency of the material and the liquid phase, the cleaning blade is driven to rotate on the inner wall of the tower body through the collar, the connecting rod and the strip plate, so as to scrape off the material adhering to the inner wall of the tower body, ensuring that the material will not adhere to the inner wall of the tower body and cannot be cleaned, resulting in corruption and deterioration, and affecting the reaction effect during secondary use, thereby providing a certain guarantee for the production environment of isopropanol;

[0015] 2. The material enters the feeding cylinder through the vertical pipe. Quantitative feeding is achieved through the second solenoid valve.
