Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to an acrylic resin polymerization reactor. Background Technology

[0002] Acrylic resin, used in the formulation of coatings for leather and certain high-end products, and in the production of acrylic resin paints, is a chemical intermediate. The polymerization reaction of acrylic resin requires extremely high precision in temperature uniformity, material mixing efficiency, and reaction rate. Existing reactors have the following drawbacks: the stirring mechanism is mostly a single blade, making it difficult to simultaneously mix materials at the bottom and top of the reactor, easily leading to incomplete local reactions. Furthermore, it cannot premix newly added materials to improve subsequent reaction efficiency. To address these problems, this invention provides a solution. Utility Model Content

[0003] The purpose of this invention is to provide an acrylic resin polymerization reactor.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An acrylic resin polymerization reactor includes a reactor body, a base, an inlet, an outlet, a motor, a stirring shaft, stirring blades, and a jacket. The base and outlet are located at the bottom of the reactor body, while the inlet and motor are installed at the top. The motor is fixedly connected to the stirring shaft inside the reactor body. The bottom end of the stirring shaft is equipped with stirring blades. A circulating mixing disc is provided inside the reactor body, dividing the reactor body into an upper mixing chamber and a lower reaction chamber. The circulating mixing disc has an annular structure, with its outer side integrated with the reactor body. The middle of the circulating mixing disc is fixedly connected to the upper end of a circulating cylinder, and the lower end of the circulating cylinder extends into the lower reaction chamber. The stirring shaft passes through the middle of the circulating cylinder, and an auger is provided on the portion of the stirring shaft located in the circulating cylinder. An annular mixing trough is provided on the circulating mixing disc, with a through-hole at the bottom. A mixing pressure plate is installed on the stirring shaft in the upper mixing chamber, with the bottom of the mixing pressure plate fitting against the bottom of the mixing trough.

[0005] Furthermore, the mixing plate is at an angle of 30°-45° to the horizontal plane. While the mixing plate rotates with the stirring shaft to mix the material, it exerts a downward pressure on the material in the upper mixing chamber, forcing the material from the leakage hole into the lower reaction chamber to form a circulating mixing process.

[0006] Furthermore, the material leakage hole is a funnel-shaped hole, with its upper end size smaller than its lower end size. The funnel shape of the material leakage hole can effectively prevent the material leakage hole from becoming blocked.

[0007] Furthermore, the bottom of the vessel is configured as a conical structure, and the stirring blade is configured as a triangular structure.

[0008] Furthermore, the liquid inlet of the jacket is located on the upper side wall, and the liquid outlet of the jacket is located on its lower side wall.

[0009] In summary, this utility model has the following beneficial effects: by setting up a circulating cylinder, auger and circulating mixing plate structure, this utility model can effectively circulate and mix the materials in the upper and lower parts of the reactor, avoid material stratification which would affect the reaction, and improve reaction efficiency.

Detailed Implementation

[0011] The present invention will be further described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0012] like Figure 1 and 2 As shown, an acrylic resin polymerization reactor includes a reactor body 1, a base 5, a feed inlet 6, a discharge outlet 7, a motor 8, a stirring shaft 9, stirring blades 12, and a jacket 15. The base 5 and the discharge outlet 7 are located at the bottom of the reactor body 1, with the outlet 7 located at the center of the bottom. The feed inlet 6 and the motor 8 are installed at the top of the reactor body 1, with the motor 8 located at the center of the top of the reactor body 1. The motor 8 is fixedly connected to the stirring shaft 9 inside the reactor body 1. The bottom end of the stirring shaft 9 is provided with stirring blades 12. A circulating mixing disc 4 is provided inside the reactor body 1. The specific structure of the circulating mixing disc 4 is described in [reference needed]. Figure 1The circulating mixing plate 4 divides the inner cavity of the vessel body 1 into an upper mixing chamber 2 and a lower reaction chamber 3. The circulating mixing plate 4 has an annular structure. The outer side of the circulating mixing plate 4 is integrated with the vessel body 1. The middle of the circulating mixing plate 4 is fixedly connected to the upper end of the circulating cylinder 10. The lower end of the circulating cylinder 10 extends into the lower reaction chamber 3. The stirring shaft 9 passes through the middle of the circulating cylinder 10. The part of the stirring shaft 9 located in the circulating cylinder 10 is equipped with an auger 11. When the auger 11 rotates with the stirring shaft 9, the material will move upward with the auger 11 and rise from the bottom of the lower reaction chamber 3 into the upper mixing chamber 2 for mixing. The circulating mixing plate 4 is equipped with an annular mixing trough. The bottom of the mixing trough is equipped with a through leakage hole 13. A mixing pressure plate 14 is installed on the stirring shaft 9 in the upper mixing chamber 2. The bottom of the mixing pressure plate 14 is in contact with the bottom of the mixing trough.

[0013] Furthermore, the mixing plate 14 is at an angle of 30°-45° to the horizontal plane. While the mixing plate 14 rotates with the stirring shaft 9 to mix the material, the mixing plate 14 will exert a downward pressure on the material in the upper mixing chamber 12, forcing the material from the discharge hole 13 into the lower reaction chamber 3 to form a circulating mixing.

[0014] Furthermore, the material leakage hole 13 is a funnel-shaped hole, with its upper end size being smaller than its lower end size. The funnel shape of the material leakage hole 13 can effectively prevent the material leakage hole 13 from becoming blocked.

[0015] Furthermore, the bottom of the vessel body 1 is set in a conical structure, and the stirring blade 12 is set in a triangular structure. This structure facilitates the discharge of the reacted material and accelerates the mixing again before discharge to ensure complete reaction and effectively prevent material settling.

[0016] Furthermore, the liquid inlet 16 of the jacket 15 is located on the upper side wall, and the liquid outlet 17 of the jacket 15 is located on its lower side wall.

[0017] Working principle: The material is added into the vessel body 1 through the feed port 6 and enters the upper mixing chamber 2. The motor 8 rotates and drives the mixing plate 14 to mix the material, while simultaneously pressing the material through the discharge hole 13 into the lower reaction chamber 3 for reaction. At the same time, the stirring blade 12 stirs and mixes the material at the bottom of the lower reaction chamber 3. When the auger 11 rotates with the stirring shaft 9, it lifts the material from the lower reaction chamber 3 to the upper mixing chamber 2, forming an up-and-down circulation to avoid material stratification and improve reaction efficiency and the degree of material reaction.

[0018] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
