Description

Technical Field

[0001] This utility model relates to the field of chemical machinery technology, and more specifically, to an epoxy resin waterproof composite material reactor. Background Technology

[0002] Epoxy resin waterproof composite material is a high-performance waterproof material made by adding specific curing agents and hydrophobic fillers to epoxy resin as the matrix. Its production process requires the uniform mixing and pre-curing reaction of each component to be completed in a closed reactor with temperature control and stirring functions.

[0003] During the mixing reaction of this type of material, due to the high viscosity of the resin system and the surface characteristics of the filler, the material is very easy to adhere to the inner wall of the reactor and accumulate to form a wall-mounted layer. This phenomenon not only significantly reduces the effective reaction volume, leading to a decrease in mixing uniformity and a decrease in heat transfer efficiency, but also puts a burden on the subsequent cleaning work of the reactor.

[0004] In view of this, we propose an epoxy resin waterproof composite material reactor. Utility Model Content

[0005] 1. Technical problems to be solved

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. This utility model uses a scraper ring driven by a first electric push rod to move axially along the inner wall of the reactor. This enables dynamic removal of materials adhering to the inner wall during the stirring operation, eliminating the volume loss and uneven heat transfer problems caused by raw materials adhering to the wall in traditional equipment, and making subsequent reactor cleaning operations more convenient.

[0019] 3.

[0030] Please see Figure 1-6 This utility model provides a technical solution:

[0031] An epoxy resin waterproof composite material reactor includes a base 1 and a reactor body 11 fixedly connected to the base 1. The reactor body 11 has an inlet 13 and an outlet 14 at its top and bottom, respectively. The top of the reactor body 11 is provided with a cover plate 12 that can be lifted and moved. A rotating rod 18 is rotatably connected to the cover plate 12. Multiple stirring rods 19 are fixedly connected to the rotating rod 18. A first electric push rod 26 is fixedly connected to the top of the rotating rod 18. A scraper ring 20 is fixedly connected to the extended end of the first electric push rod 26. This configuration provides equipment stability by fixing the reactor body 11 to the base 1. The inlet 13 and outlet 14 at the top and bottom achieve closed material flow. The liftable cover plate 12 provides operating space for internal maintenance. The scraper ring 20 can move axially independently of the stirring rods 19 through the first electric push rod 26, so that the internal wall cleaning can be carried out without stopping the machine. At the same time, the lifting function of the cover plate 12 not only facilitates the feeding but also facilitates subsequent disassembly and maintenance.

[0032] Secondly, a motor 15 is fixedly connected to the top of the cover plate 12, and a drive gear 16 is fixedly connected to the output end of the motor 15. A driven gear 17 is fixedly connected to the rotating rod 18. The drive gear 16 and the driven gear 17 are meshed together. With this arrangement, power is transmitted through the meshing of the drive gear 16 and the driven gear 17 on the rotating rod 18, isolating the power source outside the reaction chamber, making the power device easier to maintain.

[0033] Furthermore, two second electric push rods 27 are fixedly connected to the side of the reactor body 11. The extended ends of the two second electric push rods 27 are fixedly connected to the cover plate 12. This arrangement allows the reactor to quickly switch between a closed reaction state and an open maintenance or feeding state. The arrangement of the two second electric push rods 27 can also prevent deformation caused by unilateral overload and provide a stable operating environment for the scraper ring 20.

[0034] Specifically, a connecting rod 22 is fixedly connected to the extended end of the first electric push rod 26. The connecting rod 22 is fixedly connected to the scraper ring 20. The cross-section of the connecting rod 22 is rectangular, and a groove 23 adapted to the size of the connecting rod 22 is provided on the rotating rod 18. With this arrangement, the movement of the scraper ring 20 can be strictly limited to the axial direction through the cooperation design of the rectangular connecting rod 22 and the groove 23. The rectangular cross-section arrangement can further ensure the stability of the scraper ring 20 during operation.

[0035] In addition, the outer wall of the scraper ring 20 is in contact with the inner wall of the reactor body 11. The scraper ring 20 is used to clean the inner wall of the reactor body 11 when it moves up and down with the first electric push rod 26. The close contact between the outer wall of the scraper ring 20 and the inner wall of the reactor ensures the cleaning effect of the scraper ring 20 on the inner wall of the reactor body 11.

[0036] Furthermore, the top and bottom of the scraper ring 20 are provided with inclined cleaning slopes 21. The cleaning slopes 21 ensure that the scraper ring 20 can guide the scraped material back to the center of the reaction zone, prevent the material from adhering again, and prevent the scraped material from re-accumulating.

[0037] In addition, multiple stirring rods 24 are fixedly connected to the scraper ring 20, and a channel 25 is provided between the two scraper rings 20 closest to the rotating rod 18 in the vertical projection direction. The width of the channel 25 in the vertical projection direction is the same as the thickness of the stirring rod 19. This arrangement allows the stirring rods 24 on the scraper ring 20 to form a supplementary shear flow in the radial direction, improving the mixing effect. On the other hand, it also allows the two stirring rods 24 in the middle to clean the surface of the stirring rod 19 during the up-and-down movement.

[0038] Working principle:

[0039] When using the device, the second electric push rod 27 extends and drives the cover plate 12 to rise. Then, epoxy resin base material, curing agent and hydrophobic filler are injected into the reactor body 11 through the feed port 13. In the closed state, the motor 15 drives the gear 16 set to rotate the rotating rod 18, so that the stirring rod 19 fixed on it can achieve the main mixing. At the same time, the first electric push rod 26 pushes the rectangular connecting rod 22 to move axially along the slide 23, driving the scraper ring 20 to move up and down along the inner wall of the reactor. The top and bottom cleaning slopes 21 of the scraper ring 20 continuously scrape off the material adhering to the wall and guide it to the center. The stirring rod 24 on the scraper ring 20 simultaneously enhances the mixing effect during the up and down movement. During this process, the channel 25 between the scraper rings 20 closest to the rotating rod 18 in the vertical projection direction allows the rotating stirring rod 19 to be periodically scraped, and also realizes the self-cleaning of the stirring rod 19.
