Description

Technical Field

[0001] This utility model relates to the field of epoxy resin processing technology, specifically to a desolventizing device for glycidyl ester type epoxy resin. Background Technology

[0002] Glycidyl ester type epoxy resin is an epoxy resin with glycidyl ester as the active group. It has the characteristics of low viscosity, high bond strength and excellent weather resistance, and is widely used in electronic packaging, composite materials and other fields. An epoxy resin solvent removal device is a device specifically used to process and separate solvents from epoxy resins.

[0003] Existing solvent removal methods for glycidyl ester type epoxy resins typically involve evaporating the solvent through a single heating process. However, this method is relatively slow and does not facilitate continuous stirring during the solvent removal process to cut the solvent and improve the solvent removal effect. Utility Model Content

[0004] The purpose of this invention is to provide a solvent removal device for glycidyl ester type epoxy resin to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a desolventizing device for glycidyl ester type epoxy resin, comprising a desolventizing vessel, a heating layer, and a desolventizing stirring assembly. The heating layer is provided inside the desolventizing vessel, and an inner vessel body is provided inside the heating layer. The desolventizing stirring assembly is installed inside the inner vessel body, and the desolventizing stirring assembly includes a rotating shaft, connecting rods, a secondary motor, a stirring shaft, a spiral blade, and stirring blades. Four connecting rods are fixed on the outer side of the upper part of the rotating shaft, and a secondary motor is installed at the end of the connecting rods. A stirring shaft is provided on the lower side of the secondary motor, and a spiral blade is fixed on the outer side of the stirring shaft. Stirring blades are also fixed at equal intervals on the outer side of the rotating shaft. A turbulence ring is fixed on the inner wall of the inner vessel body.

[0006] Furthermore, the vertical center lines of the desolvation vessel and the inner vessel body coincide, and the heating layer is arranged in a ring shape.

[0007] Furthermore, a discharge pipe is connected to the lower middle part of the desolventizing vessel, and a feed hopper is installed on the upper side of the desolventizing vessel.

[0008] Furthermore, an evaporation recovery pipe is connected to the other side above the desolventizing vessel, and a main drive motor is installed on the upper middle part of the desolventizing vessel.

[0009] Furthermore, the output shaft of the main drive motor passes through the desolventizing vessel and is fixedly connected to the rotating shaft, with the rotating shaft located in the middle of the interior of the desolventizing vessel.

[0010] Furthermore, the four connecting rods are arranged in a cross shape, while the stirring blades are arranged in an X shape.

[0011] Furthermore, the turbulence rings are evenly distributed, and the inner wall of the turbulence rings has a serrated structure.

[0012] This invention provides a solvent removal device for glycidyl ester type epoxy resin, which has the following beneficial effects:

[0013] This invention features a heating layer and a feeding hopper for easy feeding of glycidyl ester-type epoxy resin solvent into the inner vessel. The heating layer contains a heating rod that can be electrically heated to evaporate the solvent in the epoxy resin inside the inner vessel, thereby achieving the separation of the resin from the substrate. The top evaporation recovery pipe of the desolventizing vessel is connected to a solvent vapor condensation and recovery device for condensing and recovering the solvent vapor.

[0014] This invention features a solvent extraction and stirring assembly. The main drive motor facilitates the rotation of the shaft and stirring blades, ensuring continuous stirring of the glycidyl ester epoxy resin solvent during the solvent extraction process. The shaft drives the connecting rod and secondary motor to revolve, while four sets of secondary motors and the stirring shaft drive the rotation of the spiral blades. This allows the solvent to be cut by turbulence rings evenly distributed on the inner wall of the vessel, which have a serrated structure, forming a dynamic mixing field of compression, dispersion, and polymerization. This improves mass transfer efficiency, increases the gas-liquid contact area, and thus enhances the solvent extraction effect. Attached Figure Description

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 and Figure 2 As shown, a solvent extraction device for glycidyl ester type epoxy resin includes a solvent extraction vessel 1, a heating layer 2, and a solvent extraction stirring assembly 7. The heating layer 2 is disposed inside the solvent extraction vessel 1, and an inner vessel body 3 is disposed inside the heating layer 2. The vertical center lines of the solvent extraction vessel 1 and the inner vessel body 3 coincide. The heating layer 2 is annular in shape. A discharge pipe 4 is connected to the lower middle part of the solvent extraction vessel 1, and a feed hopper 5 is installed on one side of the upper part of the solvent extraction vessel 1. An evaporation recovery pipe 6 is connected to the other side of the upper part of the solvent extraction vessel 1. A stirring assembly 7 is installed on the upper middle part of the solvent extraction vessel 1. The inner vessel 3 is equipped with a main drive motor 8 and a turbulence ring 9 fixed on its inner wall. The turbulence rings 9 are evenly distributed and have a serrated inner wall structure. The feed hopper 5 facilitates the feeding of glycidyl ester type epoxy resin solvent into the inner vessel 3. The heating layer 2 has a built-in heating rod that can be electrically heated. By heating the inner vessel 3, the solvent in the epoxy resin inside evaporates, thereby achieving the separation of the resin from the substrate. The top evaporation recovery pipe 6 of the desolventizing vessel 1 is connected to a solvent vapor condensation recovery device, which can condense and recover the solvent vapor.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, a solvent extraction stirring assembly 7 is installed inside the inner vessel body 3. The solvent extraction stirring assembly 7 includes a rotating shaft 701, connecting rods 702, a secondary motor 703, a stirring shaft 704, a spiral blade 705, and stirring blades 706. Four connecting rods 702 are fixed to the upper outer side of the rotating shaft 701, and the secondary motor 703 is installed at the end of the connecting rods 702. The stirring shaft 704 is arranged below the secondary motor 703, and the spiral blades 705 are fixed to the outer side of the stirring shaft 704. Stirring blades 706 are also fixed at equal intervals to the outer side of the rotating shaft 701. The output shaft of the main drive motor 8 passes through the solvent extraction vessel 1 and is fixedly connected to the rotating shaft 701. The rotating shaft 701 is located in the middle of the interior of the solvent extraction vessel 1. The rod 702 has a "+" shaped structure, while the stirring blade 706 has an "X" shaped structure. The main drive motor 8 facilitates the rotation of the rotating shaft 701 and the stirring blade 706, so that the glycidyl ester type epoxy resin solvent is continuously stirred during the desolvation process. The rotating shaft 701 can drive the connecting rod 702 and the secondary motor 703 to revolve. At the same time, the four sets of secondary motors 703 and the stirring shaft 704 can drive the rotation of the spiral blade 705. This allows the solvent to be cut by the turbulence rings 9, which are evenly distributed on the inner wall of the inner vessel body 3 and have a serrated inner wall structure, forming a dynamic mixing field of extrusion, dispersion and polymerization, improving mass transfer efficiency, increasing the gas-liquid contact area, and thus improving the desolvation effect.

[0023] In summary, as Figures 1-4 As shown, the desolventizing device for glycidyl ester type epoxy resin, in use, firstly feeds the glycidyl ester type epoxy resin solvent through the feed hopper 5, while the heating layer 2 has a built-in heating rod that can be electrically heated. Then, the solvent in the epoxy resin inside the inner vessel 3 is evaporated by heating, thereby achieving the separation of the resin from the substrate. The top evaporation recovery pipe 6 of the desolventizing vessel 1 is externally connected to a solvent vapor condensation recovery device, which can condense and recover the solvent vapor. In this process, the rotation of the rotating shaft 701 and the stirring blade 706 can be driven by the main drive motor 8, so that the glycidyl ester type epoxy resin solvent is removed. During the solvent removal process, the glyceryl ester type epoxy resin solvent is continuously stirred, and the rotating shaft 701 can drive the connecting rod 702 and the secondary motor 703 to revolve. At the same time, the four sets of secondary motors 703 and the stirring shaft 704 can drive the spiral blades 705 to rotate. This allows the solvent to be cut by the turbulence rings 9, which are evenly distributed on the inner wall of the inner vessel body 3 and have a serrated inner wall structure, forming a dynamic mixing field of extrusion, dispersion and polymerization, improving mass transfer efficiency, increasing the gas-liquid contact area, and thus improving the solvent removal effect. This completes the use process of the solvent removal device for the glyceryl ester type epoxy resin.
