Description

TECHNICAL FIELD

[0002] Resin stirring processing is an important link in the production and application process of resin. Stirring can ensure that all components in the resin are fully mixed, avoid local concentration unevenness, and thus improve the overall performance of the resin. In the production process of some resins, stirring helps to accelerate the progress of chemical reactions, such as curing reactions, thereby improving production efficiency. Through stirring, the viscosity, flowability and other properties of the resin can be adjusted to meet the needs of different application scenarios.

[0003] However, during stirring, a certain amount of heat is generated due to friction and collision between resin molecules. If the stirring speed is too fast, too much heat is generated, which may cause the temperature of the resin to rise sharply, thereby causing the resin to cure or degrade prematurely. This not only reduces the performance and service life of the resin, but also may adversely affect the production equipment and process.

[0004] Therefore, the application provides a stirring device for unsaturated polyester resin processing to solve the above problems. CONTENT OF THE INVENTION

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] Example 1

[0023] This embodiment provides a stirring device for processing unsaturated polyester resin, such as... Figures 1-4 As shown, the stirring device includes a stirring tank 1 and a stirring inner liner 11 inserted into the stirring tank 1. An arch frame 12 is fixedly installed on the stirring tank 1, and a first motor 13 is fixedly installed on the arch frame 12. The output end of the first motor 13 extends through the arch frame 12 toward the stirring inner liner 11, and a rotating rod 14 is fixedly installed at its end. Several evenly distributed stirring rods 15 are fixedly installed on the rotating rod 14, and a cooling mechanism 2 is provided on the stirring rods 15.

[0024] The cooling mechanism 2 includes a U-shaped mounting bracket 21 sleeved on the stirring rod 15. Several evenly distributed hoops 22 are fixedly installed on the mounting bracket 21. A metal heat-conducting pipe 23 filled with liquid nitrogen refrigerant is inserted into the hoop 22.

[0025] In use, start the first motor 13, rotate the stirring rod 15 to a position offset from the arch frame 12 and then close it to expose the stirring rod 15. Then, put the mounting bracket 21 on the stirring rod 15, and then insert the metal heat-conducting pipe 23 into the hoop 22 and fix it together with the mounting bracket 21. Then, fill the metal heat-conducting pipe 23 with refrigerant, and then pour the required mixture of unsaturated polyester resin into the mixing tank 11. Start the first motor 13, and the first motor 13 drives the stirring rod 15 to stir the material through the rotating rod 14. At the same time, the stirring drives the metal heat-conducting pipe 23 to rotate. The refrigerant in the metal heat-conducting pipe 23 absorbs the heat generated during resin processing and stirring through the outer wall of the metal heat-conducting pipe 23 and evaporates to dissipate heat, thereby avoiding overheating that could cause premature curing or thermal degradation of the resin and ensuring processing quality.

[0026] Specifically, the top of the metal heat-conducting pipe 23 is higher than the opening height of the stirring inner liner 11, and a funnel opening 24 is fixedly installed at the top of the metal heat-conducting pipe 23. During use, liquid nitrogen refrigerant is poured into the metal heat-conducting pipe 23 through the funnel opening 24, making it less likely to spill and more convenient.

[0027] More specifically, the mounting bracket 21 is slidably mounted on the stirring rod 15, and a screw 25 is screwed onto the mounting bracket 21, passing through the mounting bracket 21 and contacting the outer wall of the stirring rod 15. In use, after the mounting bracket 21 is slipped onto the top of the stirring rod 15, the mounting bracket 21 is slid left and right to adjust its position. Then, the screw 25 is inserted into the side of the mounting bracket 21 to abut against the outer wall of the stirring rod 15, thereby fixing the mounting bracket 21 and preventing it from moving during mixing, thus ensuring greater stability.

[0028] Further, the mounting frame 21 is fixedly installed with a support plate 26 which is adapted to the metal heat conducting pipe 23 at the bottom end position on the side coplanar with the hoop 22. In use, the metal heat conducting pipe 23 is inserted into the hoop 22, and the bottom of the metal heat conducting pipe 23 contacts the support plate 26, and the support plate 26 supports the metal heat conducting pipe 23, which is more stable.
