Description

Technical Field

[0001] This utility model relates to a reaction vessel, specifically to an interface agent emulsification reaction vessel, and belongs to the technical field. Background Technology

[0002] In the preparation of interface agents, polymers are typically mixed, dispersed, and subjected to appropriate heat treatment to cause their molecular chains to react and form the desired emulsion-type interface agent. The mixing, dispersion, and heating steps are usually carried out in an emulsification reactor, allowing the materials to circulate and mix within the reactor to form a relatively homogeneous emulsion. However, in actual production, insufficient mixing can easily occur in the bottom region of the emulsification reactor, creating localized flow dead zones. Therefore, a slanted motor-driven stirring component is usually installed at the bottom of the emulsification reactor. This slanted stirring component is generally a stirring disc structure with multiple short blades, which directly acts on the bottom of the reactor to provide additional shear force to the material, preventing sediment formation and promoting material circulation throughout the reactor. However, in the emulsification reaction of multi-component systems of high-viscosity interface agents, although slanted motor-driven bottom stirring enhances axial flow, radial flow of the material remains weak, and insufficient mixing may still occur in localized areas.

[0015] This invention relates to an interface agent emulsification reactor. Through the cooperation of stirring blades, turbine blades, and inclined stirring components, a uniform and efficient material mixing flow field is formed.

It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0022] In this invention, unless otherwise specified, all parts and percentages are by weight, and the equipment and raw materials used are commercially available or commonly used in the field. Unless otherwise specified, the methods in the following embodiments are conventional methods in the field. Unless otherwise specified, the components or equipment in the following embodiments are general standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0023] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0024] An embodiment of this utility model discloses an interface agent emulsification reactor, such as... Figure 1 As shown, the interface agent emulsification reactor includes a reactor body 1, an inclined motor 2, an inclined stirring component 3, a stirring drive motor 4, a stirring shaft 5, five stirring blades 6, and a turbine blade 7.

[0025] The vessel body 1 has a sealed inner cavity 101. A feed inlet 102 is located at the top of the vessel body 1, and a discharge outlet 103 is located at the bottom of the vessel body 1. An inclined motor 2 is located at the bottom of the vessel body 1. An inclined stirring component 3 is fixedly connected to the power output end of the inclined motor 2, and the inclined stirring component 3 is located at the bottom of the sealed inner cavity 101. A stirring drive motor 4 is located at the top of the vessel body 1. The power output end of the stirring drive motor 4 is fixedly connected to a stirring shaft 5, which is located within the sealed inner cavity 101. Five stirring blades 6 are fixedly spaced along the axial direction of the stirring shaft 5 on the surface of the stirring shaft 5. A turbine blade 7 is fixed to the bottom end of the stirring shaft 5, and there is a gap between the turbine blade 7 and the bottom of the sealed inner cavity 101.

[0026] The combination of stirring blades 6, turbine blades 7, and the inclined stirring component 3 creates a uniform and efficient material mixing flow field. The five stirring blades 6 on the stirring shaft 5 mainly generate axial flow, while the inclined stirring component 3 generates material flow in the inclined direction, which mainly strengthens the axial flow. The turbine blades 7 at the bottom of the stirring shaft 5 generate strong radial flow. The material at the bottom of the vessel generates strong radial flow, forming localized strong turbulence. In addition, the flow field disturbances generated by these three components produce a complex turbulent structure, which also enhances the mixing uniformity of the material inside the vessel.

[0027] Specifically, the stirring blades 6 are evenly spaced along the axial direction of the stirring shaft 5. Each stirring blade 6 includes a connecting part 601, two intermediate stirring parts 602, and two final stirring parts 603. The inner ends of one intermediate stirring part 602 are fixedly connected to each side of the connecting part 601, and the outer ends of each final stirring part 603 are fixedly connected to each of the intermediate stirring parts 602. Figure 2 As shown, both the intermediate stirring section 602 and the final stirring section 603 have inclined blade structures. The two intermediate stirring sections 602 have opposite inclination directions, the two final stirring sections 603 have opposite inclination directions, and the intermediate stirring section 602 and the final stirring section 603 fixedly connected to it also have opposite inclination directions. The combination of stirring blades 6 with different inclination directions makes the material flow direction change in the laminar flow where the stirring blade 6 is located more complex, thereby improving the degree of material mixing and dispersion.

[0028] Specifically, such as Figure 3 As shown, the turbine blade 7 includes an upper turbine disk 701, a swashplate 702, and a lower turbine disk 703 arranged sequentially from top to bottom. The upper turbine disk 701 has multiple upper disk plates 704 perpendicular to its surface, evenly spaced along the circumference of the upper turbine disk 701. The swashplate 702 has multiple downward-inclined swashplates 705, evenly spaced along the circumference of the swashplate 702. The lower turbine disk 703 has multiple lower disk plates 706 perpendicular to its surface, evenly spaced along the circumference of the lower turbine disk 703. The outer diameter of the upper turbine disk 701 is larger than the outer diameter of the lower turbine disk 703, and the outer diameter of the upper part of the swashplate 702 is larger than the outer diameter of the lower part of the swashplate 702. This three-layer structure design of the turbine blade 7 further enhances the radial thrust generated by its rotation, increasing the radial flow of materials. Furthermore, the downward-sloping blade 705 generates a portion of the flow directed toward the inclined stirring member 3, which is more likely to mix with the flow generated by the inclined stirring member 3 to form turbulence.

[0029] Specifically, to facilitate the heating treatment of the material inside the vessel, a jacket 104 is provided on the lower outer surface of the vessel body 1. The jacket 104 is a closed hollow structure, and a heating medium inlet 105 and a heating medium outlet 106 are respectively provided on both sides of the jacket 104. Hot water or steam can be introduced into the closed hollow structure inside the jacket 104, and the material inside the vessel is heated by heating the outer wall of the vessel body 1.

[0030] Specifically, a reducer 8 and a coupling 9 are provided between the stirring drive motor 4 and the stirring shaft 5. The power output end of the stirring drive motor 4 is fixedly connected to the stirring shaft 5 through the reducer 8 and the coupling 9 in sequence.

[0031] Specifically, in order to facilitate the control of the bottom discharge, the discharge port 103 is equipped with a discharge valve 107.

[0032] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
