Technical Field

[0001] The utility model relates to the technical field of silicone glue processing equipment, in particular to a silicone glue stirring reaction kettle. Background Art

[0002] Silicone glue is a paste made by mixing polydimethylsiloxane as the main raw material with various processing aids. It cures at room temperature by reacting with water in the air to form an elastic rubber, which is very convenient to use. In addition to the excellent properties of general silicone materials such as high and low temperature resistance, weather aging resistance, and high electrical insulation, silicone glue also has good adhesion to various substrates and strong anti-displacement ability, and has developed into an important sealing material for modern building decoration.

[0003] In the processing of silicone glue, stirring equipment is often used for stirring. The stirring equipment is a machine with a shaft with blades rotating in the kettle body, stirring and mixing various raw materials to make them into a mixture or a paste with appropriate consistency.

[0004] When the existing stirring equipment stirs silicone glue, since the stirring shaft is located at the center of the kettle body, and the blades on the stirring shaft generally only stir the raw materials in the central part of the kettle body, it is difficult to stir the raw materials near the edge of the kettle body, resulting in incomplete stirring and uneven mixing of the raw materials, thus affecting the quality of silicone glue.

Detailed implementation mode

[0030] The following is a further detailed description of this application in conjunction with the attached Figures 1-3 drawings.

[0031] Example:

[0032] A silicone glue stirring reactor, as Figures 1-2 shown, includes a kettle body 1, a kettle cover 2 is arranged at the top of the kettle body 1, and the kettle cover 2 is connected to the kettle body 1 by bolts. A stirring assembly 3 is arranged in the kettle body 1, and the stirring assembly 3 includes a first rotating part 31 and a second rotating part 32. Among them, the first rotating part 31 is located outside the second rotating part 32, and the rotating directions of the first rotating part 31 and the second rotating part 32 are opposite to achieve a more comprehensive and thorough stirring effect. In addition, a driving motor 4 is arranged at the top of the kettle cover 2, and its output end is connected to the stirring assembly 3 to drive the stirring assembly 3 to rotate, thereby realizing the stirring action.

[0033] As Figure 2 shown, in this embodiment, a fixed plate 21 is arranged in the kettle cover 2, and a central shaft 22 is fixed at the center of the bottom of the fixed plate 21 by welding. Both the first rotating part 31 and the second rotating part 32 are sleeved on the outer wall of the central shaft 22 and can rotate freely on the central shaft 22. The central shaft 22 provides a stable support point for the first rotating part 31 and the second rotating part 32 to ensure the stability of the stirring process.

[0034] As Figures 2-3As shown in the figure, in this embodiment, the output end of the driving motor 4 is connected with a driving gear 41 through a coupling, and the driving gear 41 is connected to the bottom of the fixed plate 21. The first rotating member 31 includes a driven gear 313, a first rotating shaft 311 and a first bevel gear 312. Among them, the driven gear 313 and the first bevel gear 312 are respectively fixedly connected to both ends of the first rotating shaft 311, and the driven gear 313 meshes with the driving gear 41. The driving motor 4 drives the driving gear 41 to rotate. Since the driven gear 313 meshes with the driving gear 41, the rotation of the first rotating member 31 is realized through the driving motor 4. Three first connecting rods 314 are fixedly arranged on the first rotating shaft 311 by welding, and an outer blade 315 is arranged at the end of each first connecting rod 314. The outer blade 315 is close to the inner wall edge of the kettle body 1 and is used for stirring the materials at the edge of the kettle body 1.

[0035] As Figures 2-3 shown in the figure, in this embodiment, the first rotating member 31 and the second rotating member 32 are connected by a transmission member 33. The transmission member 33 includes a second bevel gear 332, a third bevel gear 333 and a connecting shaft 331. Among them, the connecting shaft 331 penetrates through the central shaft 22. The second bevel gear 332 and the third bevel gear 333 are respectively sleeved on both ends of the connecting shaft 331, and both the second bevel gear 332 and the third bevel gear 333 mesh with the first bevel gear 312. When the first bevel gear 312 rotates, the second bevel gear 332 and the third bevel gear 333 rotate synchronously, and the rotation directions of the second bevel gear 332 and the third bevel gear 333 are opposite.

[0036] As Figures 2-3 shown in the figure, in this embodiment, the second rotating member 32 includes a second rotating shaft 321 and a fourth bevel gear 322. Among them, the fourth bevel gear 322 meshes with both the second bevel gear 332 and the third bevel gear 333 at the same time. Three second connecting rods 323 are fixedly arranged on the second rotating shaft 321 by welding, and an inner blade 324 is connected to the end of each second connecting rod 323. The inner blade 324 is located at the center of the kettle body 1 and is used for stirring the materials in the central part of the kettle body 1.

[0037] As Figure 2 shown in the figure, in order to ensure the sealing performance at the connection between the kettle cover 2 and the kettle body 1 during stirring, a sealing ring 7 is installed between the kettle cover 2 and the kettle body 1. During stirring, the kettle cover 2 is closely attached to the kettle body 1 to ensure that the sealing ring is effectively compressed, so as to achieve a good sealing effect. Among them, in this embodiment, the sealing ring is a rubber ring.

[0038] In addition, as Figure 1As shown in the figure, a feed inlet 5 is provided on the side wall of the kettle body 1, and a first valve 51 is installed in the feed inlet 5 to control the addition of raw materials. A discharge outlet 6 is provided at the bottom of the kettle body 1, and a second valve 61 is installed in the discharge outlet 6 to control the discharge of products. Before use, open the first valve 51, add the silicone rubber raw materials into the kettle body 1 from the feed inlet 5, then close the first valve 51, and start the stirring process. After the stirring is completed, open the second valve 61, and discharge the stirred silicone rubber from the discharge outlet 6.

[0039] Working principle: Driven by the driving motor 4, the driving gear 41 drives the driven gear 313 and the first bevel gear 312 to rotate synchronously, realizing the rotation of the outer blade 315, so as to stir the materials at the edge of the kettle body 1. At the same time, through the transmission member 33, the inner blade 324 rotates in the opposite direction to the outer blade 315 to stir the materials in the central part of the kettle body 1. By adopting the stirring method of the first rotating member 31 and the second rotating member 32 rotating in opposite directions, the raw materials in the kettle body 1 can be stirred comprehensively and thoroughly, reducing the occurrence of uneven mixing, thereby improving the uniformity and quality of the silicone rubber.
