Description

Technical Field

[0001] This utility model relates to the field of reaction vessels, and in particular to a stirring reaction vessel for rubber chemicals. Background Technology

[0002] Reactors are core equipment used in many industries such as chemical engineering, pharmaceuticals, food processing, and biotechnology for conducting chemical reactions. They provide a controlled environment within which various physical and chemical processes can be carried out efficiently and safely. Reactors provide a closed space for chemical reactions, allowing reactants to come into full contact and undergo chemical changes. Through built-in or external heating systems, reactors can precisely control the reaction temperature, ensuring the reaction proceeds under optimal conditions. Most reactors are equipped with stirring devices to ensure uniform distribution of reactants, promote mass and heat transfer efficiency, and prevent side reactions caused by localized overheating or uneven concentration. Reactors are equipped with efficient stirring devices that can thoroughly mix different rubber raw materials and various additives, ensuring uniform distribution of components. Rubber has high viscosity and requires high shear force stirring for mixing.

[0003] However, when stirring rubber chemicals, there is a problem of insufficient stirring due to the high viscosity of the rubber chemicals. In view of this, a stirring reactor for rubber chemicals is provided. Utility Model Content

[0004] The main purpose of this invention is to provide a rubber chemical stirring reactor to solve the problem of insufficient stirring of rubber chemicals with high viscosity when stirring them, as mentioned in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a rubber chemical stirring reactor is provided, comprising an insulated outer shell, a heating groove inside the insulated outer shell, an inner shell fixedly installed inside the heating groove, and a reaction chamber inside the inner shell. The reactor further comprises a stirring mechanism rotatably installed inside the reaction chamber, the stirring mechanism including a stirring shaft, a plurality of stirring rods fixedly installed on the side wall of the stirring shaft near its lower edge, and mixing blades fixedly installed between the stirring rods and the stirring shaft. The mixing blades cut the rubber chemicals to increase the stirring effect.

[0006] Furthermore, a pipe installation groove is provided on the side wall of the heating tank.

[0007] Furthermore, the pipe mounting groove has a spiral structure, and a heating pipe is fixedly installed inside the pipe mounting groove.

[0008] Furthermore, a mounting bracket is fixedly installed on the upper surface of the heat-insulating outer shell, and one end of the stirring shaft passes through the inner shell and is located inside the mounting bracket.

[0009] Furthermore, a stirring blade is fixedly installed in the middle of the side wall of the stirring shaft, and the stirring blade has a spiral structure.

[0010] Furthermore, the stirring rod has a C-shaped structure, and the side wall of the stirring rod has an oblique angle that slopes from the middle of the side wall to both ends.

[0011] Furthermore, the two ends of the mixing blade are symmetrically provided with oblique angles that slope from the middle of the sidewall of the mixing blade towards both ends.

[0012] Furthermore, the inner shell sidewall is provided with a feed inlet that communicates with the reaction chamber.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the spiral stirring blades on the stirring mechanism perform preliminary stirring and shearing on the rubber chemicals entering the reaction chamber, initially breaking up rubber lumps. When the stirring blades rotate, they generate axial and radial bidirectional shearing forces, propelling the material to circulate up and down. Several C-shaped stirring rods are fixedly installed at the lower end of the stirring shaft, and mixing blades are fixedly installed between the stirring rods and the stirring shaft. Both the stirring rods and the mixing blades have oblique angles on their sidewalls, which slope from the middle of the sidewalls to both ends. The stirring rods increase the contact area with the material, forming local vortices, while the mixing blades enhance the longitudinal shearing force, making it suitable for high-viscosity rubber. The oblique angles of the stirring rods and the mixing blades improve the shearing effect, achieving more thorough stirring. Attached Figure Description

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] This embodiment provides a rubber chemical mixing reactor, including an insulated outer shell 1, a heating groove 11 inside the insulated outer shell 1, and an inner shell 2 fixedly installed inside the heating groove 11. The double shell configuration reduces heat loss and improves temperature stability. A reaction chamber 21 is opened inside the inner shell 2. It also includes a stirring mechanism 3, which is rotatably installed in the reaction chamber 21. The stirring mechanism 3 includes a stirring shaft 31, and a plurality of stirring rods 33 are fixedly installed on the side wall of the stirring shaft 31 near the lower edge. A mixing blade 331 is fixedly installed between the stirring rods 33 and the stirring shaft 31. The mixing blade 331 cuts the rubber chemical to increase the stirring effect.

[0025] like Figure 3 As shown, a pipe installation groove 12 is provided on the side wall of the heating tank 11;

[0026] like Figure 2 , Figure 3 As shown, the pipe mounting groove 12 has a spiral structure, and a heating tube 121 is fixedly installed inside the pipe mounting groove 12. The heating tube 121 is spirally arranged along the pipe mounting groove 12, which increases the heating contact area, makes the inner shell 2 heat more evenly, and avoids local overheating and heating dead corners.

[0027] like Figure 2 As shown, a mounting bracket 22 is fixedly installed on the upper surface of the heat-insulating outer shell 1. One end of the stirring shaft 31 passes through the inner shell 2 and is located inside the mounting bracket 22. A motor is fixedly installed inside the mounting bracket 22. The motor output shaft is fixedly connected to the stirring shaft 31. The motor provides power for the rotation of the stirring shaft 31.

[0028] like Figure 4 As shown, a stirring blade 32 is fixedly installed in the middle of the side wall of the stirring shaft 31. The stirring blade 32 has a spiral structure. The spiral stirring blade 32 performs preliminary stirring and shearing on the rubber chemicals entering the reaction chamber 21, and initially breaks up the rubber lumps. When the stirring blade 32 rotates, it generates axial and radial bidirectional shearing forces, which promote the material to circulate up and down.

[0029] like Figure 2 , Figure 4 As shown, the stirring rod 33 has a C-shaped structure. The side wall of the stirring rod 33 has an oblique angle that slopes from the middle of the side wall to both ends. The stirring rod 33 increases the contact area with the material, forming a local vortex and further improving the stirring and shearing effect.

[0030] like Figure 4As shown, the mixing blade 331 has symmetrically opened oblique angles at both ends, which are inclined from the middle of the side wall of the mixing blade 331 to both ends, which can enhance the longitudinal shear force of the mixing blade 331 to make it suitable for high viscosity rubber.

[0031] like Figure 1 , Figure 2 As shown, the inner shell 2 has a feed inlet 211 on its side wall that connects to the reaction chamber 21, and rubber chemicals are added from the feed inlet 211.

[0032] In practical use, the rubber chemicals are added into the reaction chamber 21 through the feed inlet 211. The inner shell 2 is fixedly installed in the heating tank 11 of the heat-insulating outer shell 1 to reduce heat loss and improve temperature stability. The side wall of the heating tank 11 is provided with a spiral pipe installation groove 12. A heating pipe 121 is fixedly installed in the pipe installation groove 12. The inner shell 2 is heated by the heating pipe 121. The heating pipe 121 is spirally arranged along the pipe installation groove 12, which increases the heating contact area and makes the inner shell 2 more evenly heated, avoiding local overheating and heating dead zones. A stirring mechanism 3 is rotatably installed inside the reaction chamber 21. The stirring mechanism 3 includes a stirring shaft 31, and stirring blades 32 are fixedly installed on the middle of the side wall of the stirring shaft 31. The spiral stirring blades 32 perform preliminary stirring and shearing on the rubber chemicals entering the reaction chamber 21, and initially break up the rubber lumps. When the stirring blades 32 rotate, they generate axial and radial bidirectional shearing forces, which push the material to circulate up and down. Several C-shaped stirring rods 33 are fixedly installed at the lower end of the stirring shaft 31. Mixing blades 331 are fixedly installed between the stirring rods 33 and the stirring shaft 31. The side walls of the stirring rods 33 and the mixing blades 331 are all provided with an angle that slopes from the middle of the side wall to both ends. The stirring rods 33 increase the contact area with the material and form local vortices. The mixing blades 331 enhance the lateral shearing force to be suitable for high viscosity rubber. The angle between the stirring rods 33 and the mixing blades 331 improves the shearing effect and achieves more thorough stirring.
