Abstract
Description
Technical Field
[0001] This utility model relates to the field of degassing device technology, specifically to an epoxy resin degassing device. Background Technology
[0002] During the production, compounding, and modification of epoxy resins, air bubbles can easily be introduced due to the mixing and stirring of raw materials. At the same time, low-boiling-point volatile substances may remain. If these are not effectively removed, they will seriously affect the mechanical properties, insulation, and appearance quality of the product.
[0003] Existing degassing technologies include vacuum degassing, which relies on sealed containers and vacuum equipment, resulting in high costs and limited efficiency for high-viscosity systems; simple stirring degassing is prone to secondary air introduction due to turbulence, leading to incomplete degassing; while nitrogen purging can assist in bubble removal, traditional purging devices are mostly single-pipe direct injection, resulting in uneven gas distribution and difficulty in coordinating with the stirring process, leading to significant microbubble residue problems. Furthermore, in existing equipment, stirring and degassing components are often independently installed, resulting in low integration and complex operation, which is not conducive to efficient bubble removal in continuous production. Therefore, there is an urgent need for a device that can achieve synergistic effects of stirring and nitrogen purging, with a compact structure and superior degassing performance. Utility Model Content
[0004] Technical problems to be solved In view of the above-mentioned shortcomings of the existing technology, the present invention provides an epoxy resin degassing device, which can effectively solve the problems in the existing technology.
[0005] Technical solution
[0006] This utility model provides an epoxy resin degassing device, including a mounting platform. A ring-shaped limiting plate is fixed to the top of the mounting platform, and a stirring tank is placed in the middle of the limiting plate. A power unit and a purging assembly are provided at the bottom of the mounting platform. The output end of the power unit is connected to the drive wheel via a belt. The top of the drive wheel is fixedly connected to the power head. The top of the power head is sleeved and fixed to the bottom of the stirring blade. The purging assembly includes a collecting frame fixed to the bottom of the mounting platform and a thin tube provided at the top of the collecting frame. The thin tube is inserted into the mounting platform.
[0007] Furthermore, the top of the mixing tank is covered with a cover plate, the top of the mixing blade is fixed to the cover plate by a bearing seat, and the bearing seat structure is fixed to the bottom of the cover plate by a base.
[0008] Furthermore, the middle part of the power head is secured in the mounting platform by a bearing structure, and the bottom end of the stirring blade is fixed with a paddle.
[0009] Furthermore, the collection frame consists of two interconnected hollow annular frame structures, and a through hole is opened at the top of the collection frame, into which the thin tube is inserted.
[0010] Furthermore, one end of the collection frame is connected to an external high-pressure nitrogen source via a pipe.
[0011] Furthermore, the bottom end of the power unit is fixed to the base plate, and the base plate is fixed to the bottom of the mounting platform.
[0012] Beneficial effects
[0013] In this invention, the device drives the stirring blades to stir the epoxy resin through a power unit, while high-pressure nitrogen is introduced into the stirring tank through the thin tube of the purging component. The flow generated by stirring promotes the aggregation of bubbles, and the nitrogen carries the bubbles out together during the rising process, realizing the synergistic effect of stirring and nitrogen purging, which significantly improves the degassing efficiency, especially for the removal of micro bubbles.
[0014] In this device, the purging assembly adopts two sets of interconnected hollow annular frame structures for collecting frames, and with multiple sets of thin tubes at the top, it can evenly disperse high-pressure nitrogen gas and introduce it into the resin system, solving the problem of uneven gas distribution during traditional single-pipe purging and ensuring that there are no local dead corners in the degassing process.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0020] Example: An epoxy resin degassing device, as shown in the attached document. Figure 1 -Appendix Figure 5 The system includes a mounting platform 1, with an annular limiting plate 11 fixed at the top of the mounting platform 1. A mixing tank 2 is placed in the middle of the limiting plate 11. A power unit 4 and a purging assembly 3 are provided at the bottom of the mounting platform 1. The output end of the power unit 4 is connected to the drive wheel 41 via a belt. The top of the drive wheel 41 is fixedly connected to the power head 42. The top of the power head 42 is sleeved and fixed to the bottom of the mixing blade 22. The purging assembly 3 includes a collection frame 31 fixed at the bottom of the mounting platform 1 and a thin tube 32 provided at the top of the collection frame 31. The thin tube 32 is inserted into the mounting platform 1. The top of the mixing tank 2 is covered with a cover plate 21. The top of the stirring blade 22 is fixed to the cover plate 21 by a bearing seat, and the bearing seat structure is fixed to the bottom of the cover plate 21 by a base 24. The device drives the stirring blade 22 to stir the epoxy resin through the power device 4. At the same time, high-pressure nitrogen is introduced into the mixing tank 2 through the thin tube 32 of the purging component 3. The flow generated by stirring causes the bubbles to aggregate. The nitrogen carries the bubbles out together during the rising process, realizing the synergistic effect of stirring and nitrogen purging, which significantly improves the degassing efficiency, especially the removal effect of micro bubbles.
[0021] The middle part of the power head 42 is fixed in the mounting platform 1 through a bearing structure, and the bottom end of the stirring blade 22 is fixed with a paddle 23; the collecting frame 31 is a two-set interconnected hollow annular frame structure, and a through hole 13 is opened at the top of the collecting frame 31, and the thin tube 32 is inserted into the through hole 13; one end of the collecting frame 31 is connected to an external high-pressure nitrogen source through a pipe; the purging assembly 3 adopts a two-set interconnected hollow annular frame structure collecting frame 31, which, together with multiple sets of thin tubes 32 at the top, can evenly disperse high-pressure nitrogen and introduce it into the resin system, solving the problem of uneven gas distribution during traditional single-pipe purging, and ensuring that there are no local dead corners in the degassing process; the power unit 4, the purging assembly 3, the stirring blade 22 and the stirring tank 2 are integrated into one unit through the mounting platform 1, the base plate 12 and other structures, the top end of the stirring blade 22 is fixed on the cover plate 21 through a bearing seat, and the bottom end is linked with the power head 42, the overall structure is stable, the equipment space is reduced, and it is easy to operate and maintain, making it suitable for small-scale continuous production scenarios.
[0022] The bottom of the power unit 4 is fixed to the base plate 12, which is fixed to the bottom of the mounting platform 1. The stirring speed of the stirring blade 22 can be precisely controlled by the power unit 4. Combined with the sealing effect of the cover plate 21 on the stirring tank 2, the risk of secondary air mixing during the stirring process is reduced. At the same time, nitrogen, as an inert gas, can isolate air and prevent the resin from oxidizing due to contact with oxygen, thus taking into account both degassing and protection functions. The device can be adapted to epoxy resin systems of different viscosities (such as high-viscosity resins with added fillers) by adjusting the nitrogen pressure, stirring speed, and degassing time. The detachable design of the thin tube 32 and the collection frame 31 facilitates cleaning and replacement, improving the practicality of the equipment.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
