Description

Technical Field

[0002] Carboxylic acid polymerization is an important class of organic chemical reactions, often divided into condensation polymerization and addition polymerization. It involves the process of forming polymers by chemical bonds between carboxylic acid molecules or with other molecules. In carboxylic acid polymerization, the choice of feeding method has a significant impact on the reaction process and product quality. Common feeding methods include single-feed method, continuous dripping method and batch feeding method.

[0003] During the process of adding raw materials to the reactor, if the initial state of the added raw materials differs too much from the initial state of the reactor, it will affect the normal progress of the reaction. For example, if the temperature difference between the added raw materials and the reactor is large, it will cause large temperature fluctuations in the reaction system, thereby affecting the reaction rate and product quality. At the same time, if the raw materials are not mixed evenly, it will lead to uneven concentration distribution of each component in the reaction system, thereby affecting the reaction rate and product quality.

[0022] Example 1

[0023] like Figure 1-4 The image shown is the first embodiment of this utility model. This embodiment provides a feeding mechanism for a carboxylic acid polymerization reaction, comprising:

[0026] like Figure 1-4As shown, the mixing tank 101 serves as the main container for the reaction, used to hold and mix the raw materials required for the carboxylic acid polymerization reaction, and to provide space for mixing and heating, so as to better add them to the reactor and reduce the impact on the reaction of the materials in the reactor. The feeding structure 102 facilitates the addition of raw materials. The discharge pipe 103 is used to discharge the product from the mixing tank 101 to the reactor after the reaction is completed, thus serving as a feeding function. The gasket 104 enhances the stability of the discharge pipe 103.

[0027] Example 2

[0028] Reference Figure 1 and 4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0029] In this embodiment, the feeding structure 102 includes a feeding hopper 1021, which is located at the top of the mixing tank 101 and is fixedly connected to the mixing tank 101.

The fixing plate 2043 can enhance the stability of the stirring rod 2042 and ensure the uniformity of stirring.

[0037] When adding materials during use, first add the raw materials into the mixing tank 101 through the feeding hopper 1021. After adding, control the operation of the heating grid 201 through the temperature controller 202 to heat the raw materials inside the mixing tank 101 to the same temperature as the reactor. At the same time, the stirring rod 2042 can be rotated by starting the motor 2041 to stir the raw materials and mix them thoroughly. After the temperature and concentration are the same as the materials in the reactor, lift the mixing tank 101 through the handle on the top of the mixing tank 101 and take it out from the inside of the support base 106. Then, extend the discharge pipe 103 into the feed port of the reactor, and add the raw materials into the reactor by opening the control valve.
