Description

Technical Field

[0001] The utility model relates to the technical field of antioxidant processing, in particular to a stirring mechanism and a reaction kettle thereof. Background Art

[0002] Antioxidants are a class of chemical substances. When only a small amount of them exists in a polymer system, they can delay or inhibit the oxidation process of the polymer, thus preventing the aging of the polymer and extending its service life. They are also known as "anti-aging agents". Antioxidant BHT is an additive widely used in the ink, adhesive, leather, foundry, printing and dyeing, coating and electronics industries. When it is processed, a reaction kettle is required to heat the materials.

[0003] When the existing reaction kettle is used to stir raw materials, most of them only have a set of stirring structures to stir the raw materials. When this stirring equipment is used, the stirring area is limited, which affects the stirring efficiency of the raw materials. And when this stirring equipment is used, since it stirs in one direction, the raw materials will be stratified due to the influence of inertia, affecting the stirring effect.

[0004] Therefore, we propose a stirring mechanism and a reaction kettle thereof. Content of the Utility Model

The convex surface is a convex structure, and the groove extends to the outer walls on both the upper and lower sides of the auxiliary stirring blades.

[0011] A plurality of pressure relief holes arranged in a matrix are formed in the auxiliary stirring fan blades. The pressure relief holes completely penetrate the pressure relief holes, and the pressure relief holes can be cylindrical grooves.

[0012] Furthermore, the servo motor is fixedly connected to the axial position at the top of the reaction kettle body through a motor bracket. A through hole is formed in the top of the reaction kettle body. The stirring shaft is rotatably connected in the through hole and is arranged at the output end of the servo motor. The main stirring fan blades are linearly arranged on the outer walls on both sides of the stirring shaft, and the main stirring fan blades are of a rectangular structure.

[0031] As Figure 2 and Figure 3 shown, the second transmission shaft 30 is rotatably connected to the position of the main stirring fan blade 22 away from the stirring shaft 21, the auxiliary stirring fan blade 31 is fixedly connected to the axial position at one end of the second transmission shaft 30, and the auxiliary stirring fan blade 31 is in a rectangular structure.

[0032] On the upper and lower ends of the secondary stirring fan blade 31, a groove 32 is provided on one side with a staggered arrangement. The groove 32 is arranged at the end face, and the groove 32 is of a concave structure.

[0033] On the upper and lower ends of the secondary stirring fan blade 31, a convex surface 33 is provided on one side with a staggered arrangement. The convex surface 33 is located on the outer wall of the other side of the groove 32. The convex surface 33 is of a convex structure, and the groove 32 extends to the outer walls on the upper and lower sides of the secondary stirring fan blade 31.

[0034] In summary, through the main stirring mechanism and the secondary stirring mechanism provided, the design of the secondary stirring fan blade 31 can expand the stirring area of the raw materials, improve the stirring efficiency, and stir through the rotation of the main stirring fan blade 22 and the secondary stirring fan blade 31 in the horizontal and vertical directions, avoiding stratification of the raw materials under the inertia of rotation in one direction and affecting the stirring effect.

[0035] Example 2: On the basis of Example 1, referring to Figure 4 , a plurality of pressure relief holes 34 arranged in a matrix are provided in the secondary stirring fan blade 31. The pressure relief holes 34 completely penetrate the pressure relief holes 34, and the pressure relief holes 34 can be cylindrical grooves.

[0036] Through the provided pressure relief holes 34, when stirring the raw materials, at this time, a part of the raw materials can pass through the pressure relief holes 34 to reduce the impact stress on the middle part of the secondary stirring fan blade 31, avoiding the influence of this part of the stress on the rotation of the secondary stirring fan blade 31 and affecting the stirring effect.

[0037] Example 3: On the basis of Example 1, referring to Figure 5 , a plurality of first transmission shafts 23 arranged linearly are rotatably connected to the top and bottom of the main stirring fan blade 22. A dispersion block 24 is fixedly connected to the end of the first transmission shaft 23 far from the main stirring fan blade 22.

[0039] Working principle of the utility model: When stirring is required, raw materials are added into the reaction kettle body 10 through the feed inlet 11. At this time, the servo motor 20 is started, and the servo motor 20 can drive the main stirring fan blade 22 thereon to rotate through the stirring shaft 21 to stir the raw materials. At this time, the second transmission shaft 30 and the auxiliary stirring fan blade 31 rotate synchronously with the main stirring fan blade 22 around the stirring shaft 21. When the raw materials impact the convex surface 33, the raw materials impacting thereon can be guided out of the auxiliary stirring fan blade 31 through its convex surface, reducing the stress of the impact on the convex surface 33. Away from the impact to the groove 32, it can impact along its concave surface to the concave bottom of the groove 32, increasing the stress received on the groove 32. Then, a stress difference is generated with the convex surface 33 to drive the auxiliary stirring fan blade 31 and the second transmission shaft 30 to rotate, stirring the raw materials in the vertical direction. After stirring is completed, the solenoid valve can be opened and the materials can be discharged through the discharge outlet 12.
