Description

Technical Field

[0001] This utility model relates to the field of resin production technology, and more specifically, to a polyester resin production apparatus. Background Technology

[0002] Polyester resin is a polymer compound made from polybasic acids and polyols through a polycondensation reaction. It has a wide range of applications in the industrial field. Polyester resin has high strength and hardness, especially after the addition of reinforcing materials such as glass fiber, its mechanical properties can be greatly improved. It can be used to manufacture various products that withstand large external forces, such as automotive parts and aerospace structural components. Cured polyester resin has good resistance to many chemicals and can resist the corrosion of chemical media such as acids, alkalis, and salts. It can be used to manufacture chemical equipment, pipelines, storage containers, etc. In the processing of polyester resin, a mixing device is used to directly stir and mix polyester resin powder with other materials. Because polyester resin powder may clump after being transported and stored under pressure, it is necessary to perform mixing and dispersion operations on polyester resin.

[0003] In related technologies, during the use of a mixing device, a motor typically drives a mixing frame to mix the polyester resin powder and other materials added to the mixing drum for use.

[0004] However, during the current use of the mixing device, it is difficult to disperse the agglomerated polyester resin powder during the mixing process, resulting in insufficient mixing of the agglomerated polyester resin powder, which affects the mixing and dispersion effect and the mixing effect of the polyester resin.

[0030] Reference Figures 1-4This utility model provides a technical solution: a polyester resin production device, including a tank 1 and a feeding and dispersing mechanism. A motor 2 is installed on the top of the tank 1, and a stirring shaft 3 connected to the motor 2 is installed inside the tank 1. This allows the polyester resin powder to enter the tank 1 while simultaneously filtering and dispersing the polyester resin powder inside the tank 1, so that the polyester resin powder can be stirred and mixed inside the tank 1. This improves the mixing and dispersing effect and the mixing effect of the tank 1.

[0031] Reference Figures 1-4 In a preferred embodiment, the feeding and dispersing mechanism includes a feed inlet 4, which is located on both sides of the top of the tank 1. A feed head 5 is movably connected to the top of the feed inlet 4, a dispersing frame 6 is movably connected to the bottom of the feed head 5, and a dispersing cylinder 7 is movably connected to the bottom of the dispersing frame 6. A dispersing connection mechanism is fixedly connected to the top of the surface of the stirring shaft 3. External polyester resin powder is added into the dispersing cylinder 7 through the feed head 5 and the feed inlet 4. At this time, the dispersing cylinder 7 rotates under the influence of the stirring force of the stirring shaft 3, thus dispersing the incoming polyester resin powder. The filtration and dispersion process promotes the dispersion of agglomerates in the polyester resin powder. The dispersion connection mechanism includes a connecting frame 8, a connecting ring 9, and a connecting frame 10. The connecting frame 8 is fixedly connected to the top of the surface of the stirring shaft 3, the connecting ring 9 is fixedly connected to the outside of the connecting frame 8, and the connecting frame 10 is fixedly connected to the outside of the dispersion cylinder 7. This allows for the dispersion connection between the stirring shaft 3 and the dispersion cylinder 7. With the stirring force of the rotating stirring shaft 3, the dispersion cylinder 7 is driven to rotate, thus performing filtration and dispersion of the incoming polyester resin powder. This improves the dispersion effect of the dispersion cylinder 7 and the dispersion frame 6.

[0032] Reference Figures 2-3 In a preferred embodiment, contact grooves 11 are provided on the outer sides of both the connecting ring 9 and the connecting frame 10. A contact ring 12 is fixedly connected inside the contact groove 11, which can prevent slippage between the connecting ring 9 and the connecting frame 10 during operation, thus improving the connection effect between the connecting ring 9 and the connecting frame 10. A movable groove 13 is provided on the top of the connecting frame 10, and a movable bead 14 that contacts the feed head 5 is movably connected inside the movable groove 13, which can make movable contact between the connecting frame 10 and the feed head 5, thus improving the smoothness of the operation of the connecting frame 10.

[0033] Reference Figures 2-4In a preferred embodiment, by providing stabilizing ports 15 at the bottom of both the dispersing cylinder 7 and the connecting frame 10, and movably connecting a stabilizing plate 16 to the bottom of the stabilizing port 15, and having the top of the stabilizing plate 16 in contact with the bottom of the dispersing frame 6, a through-support and stabilizing operation can be provided between the dispersing cylinder 7 and the dispersing frame 6, thus improving the working stability of the dispersing cylinder 7 and the dispersing frame 6. A threaded groove 17 is provided at the bottom of the dispersing frame 6, and a stud 18 is threadedly connected inside the threaded groove 17. The bottom of the stud 18 is fixedly connected to the top of the stabilizing plate 16, which can provide a medium for the stabilizing plate 16 to connect with the dispersing frame 6 and support and stabilize the dispersing cylinder 7, thus improving the connection, support and stabilization effect of the stabilizing plate 16.

[0034] Reference Figures 2-4 In a preferred embodiment, a fixing frame 19 located inside the dispersing cylinder 7 is fixedly connected to the bottom of the feed head 5. The bottom of the fixing frame 19 is fixedly connected to the top of the dispersing frame 6, which can connect and fix the dispersing frame 6 and the feed head 5, thus improving the connection effect between the dispersing frame 6 and the feed head 5. Sealing rings 20 located outside the feed inlet 4 are movably connected to both sides of the top of the tank body 1. The top of the sealing ring 20 is fixedly connected to the bottom of the feed head 5, which can connect and seal the feed inlet 4 and the feed head 5, thus improving the sealing effect between the feed inlet 4 and the feed head 5.

[0035] Specifically, the working process or working principle of this polyester resin production device is as follows: During use, when the motor 2 is connected to an external power controller, the motor 2 drives the stirring shaft 3 to rotate inside the tank 1. Through the feed head 5 and feed inlet 4, external polyester resin powder is added to the dispersion cylinder 7. At this time, the sealing ring 20, in conjunction with the bolts threaded between the feed head 5 and the tank 1, seals the connection between the feed head 5 and the feed inlet 4. Simultaneously, the connecting frame 8 drives the connecting ring 9 to rotate with the stirring shaft 3, causing the connecting ring 9 to drive the dispersion cylinder 7 to rotate at the bottom of the feed head 5 via the connecting frame 10. At the same time, the contact groove 11, in conjunction with the contact ring 12, provides contact and anti-slip protection between the connecting frame 10 and the connecting ring 9, causing the dispersion cylinder 7 to rotate and filter and disperse the incoming polyester resin powder. During this process, because the dispersion cylinder 7 is a perforated mesh cylinder, the incoming polyester resin powder, after being filtered by the dispersion cylinder 7, moves downwards under the influence of gravity. The feed head 5 is moved into the tank 1 so that the stirring shaft 3 can stir and mix the polyester resin powder. The lumps in the polyester resin powder are filtered by the dispersion cylinder 7 and remain inside the dispersion cylinder 7. Under the influence of the rotation force of the dispersion cylinder 7 and its own gravity, it moves irregularly inside the dispersion cylinder 7, contacting and colliding with the dispersion frame 6 and the inner wall of the dispersion cylinder 7, so that the dispersion cylinder 7 and the dispersion frame 6 can work together to filter and disperse the polyester resin powder. At this time, the fixed frame 19 connects and fixes the dispersion frame 6 and the feed head 5 to ensure the working stability of the dispersion frame 6. At the same time, the movable groove 13 drives the movable ball 14 to rotate with the connecting frame 10, and the connecting frame 10 and the bottom of the feed head 5 can make rolling contact. Meanwhile, the stabilizing port 15 works with the stabilizing plate 16, and the screw groove 17 works with the screw stud 18 to support and stabilize the connecting frame 10, the dispersion cylinder 7 and the dispersion frame 6, so as to ensure that the dispersion cylinder 7 can stably stir, feed and disperse the polyester resin powder.

[0036] It should be noted that the tank body 1, the motor 2 and the stirring shaft 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
