Description

Technical Field

[0001] This utility model relates to the field of resin processing equipment technology, and more specifically, to a degassing device for high-viscosity resin. Background Technology

[0002] In modern industry, high-viscosity resins are widely used in high-end manufacturing sectors such as aerospace, electronics, and automobile manufacturing due to their excellent physicochemical properties. However, high-viscosity resins are prone to trapping a large number of air bubbles during production. If these bubbles are not effectively removed, they will form defects such as pores and voids after the resin cures, severely reducing the mechanical properties, insulation properties, and appearance quality of the products, thereby affecting the reliability and service life of the final products. Therefore, the degassing process has become a key step in determining the quality of high-viscosity resin products.

[0003] Currently, common degassing devices for high-viscosity resins on the market mainly employ single stirring or simple vacuum-assisted degassing methods. However, due to the poor fluidity and low uniformity of bubble dispersion of high-viscosity resins, traditional stirring units struggle to penetrate deep into the material, resulting in insufficient bubble breakage and difficulty in removing numerous tiny bubbles. In actual production, even after prolonged stirring, a significant number of bubbles remain inside the resin, causing the strength, toughness, and other properties of subsequent products to fail to meet expected standards, thus hindering the improvement of product qualification rates.

[0004] Furthermore, the existing multi-stage degassing section design has significant flaws. Most devices use traditional bottom end caps with a gentle angle, making it difficult to drain the material. After each production run, residual material not only wastes raw materials and increases production costs but also requires substantial manpower and time for cleaning. During cleaning, residual resin easily solidifies and hardens, further increasing the difficulty of cleaning. Simultaneously, cleaning operations may damage the internal structure of the tank, shortening the equipment's lifespan. Frequent cleaning and equipment maintenance severely impact production efficiency, becoming a bottleneck restricting the development of high-viscosity resin production enterprises. Therefore, it is necessary to propose a high-viscosity resin degassing device to at least partially solve the problems existing in the current technology. Utility Model Content

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0028] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0029] like Figures 1-8 As shown, this utility model provides a high-viscosity resin degassing device, including: a device body 100, the device body 100 including a lid 1, a body 2, a stirring section 3, and a multi-stage degassing section 4, wherein the lid 1 is mounted on the upper end of the body 2 and is fixedly connected to the upper flange 204 of the body 2, the stirring section 3 is mounted on the lid 1 and extends partially into the body 2, and the multi-stage degassing section 4 is mounted on the stirring section 3 and located inside the body 2. During use, resin is added to the body 2, and the resin enters... After entering the barrel 2, the resin first undergoes degassing treatment in the multi-stage degassing section 4, and then flows to the lower middle part of the barrel 2. The stirring section 3 can stir the resin in the lower middle part of the barrel 2, which can improve the degassing effect. Furthermore, the bottom of the barrel 2 has a conical cylinder seat 21, which makes the entire barrel 2 present a frustum-shaped structure that is wider at the top and narrower at the bottom. The conical design of the conical cylinder seat 21 makes it easier for the resin to be discharged by gravity, greatly reducing resin residue, facilitating subsequent cleaning, and effectively reducing production costs.

[0030] Furthermore, in some embodiments of this utility model, an observation sight glass 101, a light source sight glass 102, and a feeding bucket 103 are configured and installed on the bucket lid 1, wherein the observation sight glass 101 and the light source sight glass 102 are respectively located on both sides of the feeding bucket 103. The light source sight glass 102 can provide a light source into the bucket body 2, and the observation sight glass 101 can provide a clear view of the working conditions inside the bucket body 2, which is convenient for the operator to observe; while the operator can open the feeding bucket 103 and manually add resin through the feeding bucket 103.

[0031] Furthermore, some embodiments of this utility model provide a specific structure for the aforementioned barrel body 2. Here, the barrel body 2 of this structure includes an inner barrel 201 and an outer barrel 202. The upper middle part of the inner barrel 201 is installed inside the outer barrel 202, so that the inner barrel 201 can be partially configured and installed inside the outer barrel 202. In this way, there is a space between the inner barrel 201 and the outer barrel 202. The space contains a temperature-controlled medium (water). A heater and a temperature sensor are installed at the bottom of the outer barrel 202. In this way, the heater can heat the temperature-controlled medium, and the temperature sensor can detect the temperature, so that the resin in the inner barrel 201 is heated within a suitable temperature to improve its fluidity.

[0032] The aforementioned barrel lid 1 is installed at the upper end of the inner barrel 201, while the conical cylindrical seat 21 is installed at the lower end of the inner barrel 201 and located inside the outer barrel 202. The discharge pipe 211 of the conical cylindrical seat 21 passes through the bottom cover 2021 of the outer barrel 202, thereby realizing the installation of the components between the inner barrel 201 and the outer barrel 202, which facilitates the degassing of the resin. Furthermore, the aforementioned discharge pipe 211 is connected to the inner barrel 201 through a circulation mechanism 5. Specifically, the circulation mechanism 5 includes a circulation pump 51, a first circulation pipe 52, and a second circulation pipe 53. The circulation pump 51 is connected to the inner barrel 201 through the first circulation pipe 52. The feed pipe 211 is connected to the lid 1 of the inner barrel 201 via the second circulation pipe 53. Here, there is a guide pipe 11 on the inner side of the lid 1, which is located above the multi-stage degassing section 4. The second circulation pipe 53 is connected to the guide pipe 11. So when the circulation pump 51 is started, the resin in the inner barrel 201 is circulated back into the inner barrel 201 through the discharge pipe 211, the first circulation pipe 52, the second circulation pipe 53, and the guide pipe 11, and then back to the multi-stage degassing section 4. After the action of the multi-stage degassing section 4 and the stirring section 3, the degassing process is carried out, thereby realizing the removal of air bubbles from the resin.

[0033] Furthermore, some embodiments of this utility model provide a specific structure of the above-mentioned stirring part 3. Here, the stirring part 3 of this structure includes a power source 301, a stirring shaft 303, a frame stirrer 304, and an anchor stirrer 305. The power source 301 is configured and installed on the bucket cover 1, while the stirring shaft 303 is configured and installed inside the bucket body 2 and connected to the power source 301 through a coupling 302. The frame stirrer 304 and the anchor stirrer 305 are configured and installed on the stirring shaft 303. The power source 301 can be a motor. So when the power source 301 is started, it drives the stirring shaft 303 to rotate. Then, the stirring shaft 303 drives the frame stirrer 304 and the anchor stirrer 305 to rotate synchronously, thereby realizing the function of stirring the resin and causing the air bubbles inside the resin to detach.

[0034] Furthermore, some embodiments of this utility model provide a specific structure for the multi-stage degassing section 4 described above. This multi-stage degassing section 4 includes a first-stage degassing disc 401, a second-stage degassing disc 402, a third-stage degassing disc 403, a fourth-stage degassing disc 404, and a degassing disc fixing cylinder 405. The degassing disc fixing cylinder 405 is mounted on the bottom of the lid 1 and sleeved around the outside of the stirring section 3. Specifically, it is sleeved on the stirring shaft 303, and the diameter of the degassing disc fixing cylinder 405 is larger than the diameter of the stirring shaft 303, so that the rotation of the stirring shaft 303 will not affect the use of the degassing disc fixing cylinder 405. The first-stage degassing disc 401, the second-stage degassing disc 402, the third-stage degassing disc 403, and the fourth-stage degassing disc 404 are sequentially mounted on the degassing disc fixing cylinder 405 from top to bottom.

[0035] Furthermore, the first-stage debubbling disc 401 is mounted flat on the debubbling disc fixing cylinder 405, and multiple drip holes 4011 are provided on the first-stage debubbling disc 401. The upper end of the second-stage debubbling disc 402 is connected to the debubbling disc fixing cylinder 405, and the second-stage debubbling disc 402 is funnel-shaped, with the upper diameter smaller than the lower diameter. The lower end of the third-stage debubbling disc 403 is connected to the debubbling disc fixing cylinder 405, and the third-stage debubbling disc 403 is inverted funnel-shaped, with the lower diameter smaller than the upper diameter. Multiple side holes 4031 are provided between the lower end of the third-stage debubbling disc 403 and the outer wall of the debubbling disc fixing cylinder 405. The fourth-stage debubbling disc 404 is similar to the second-stage debubbling disc 402 and is also funnel-shaped. In use, the resin leaks in droplets through the dripping hole 4011 onto the second-stage degassing disc 402 below. It then spreads downwards on the surface of the second-stage degassing disc 402, flowing as a thin film. During this process, bubbles are detached due to the extension and flow of the resin. Similarly, the resin passes sequentially through the third-stage degassing disc 403 and the fourth-stage degassing disc 404. Through layer-by-layer degassing, the bubbles rupture from the inside due to pressure differences, thus achieving the removal of bubbles from the material.

[0036] Furthermore, in some embodiments of this utility model, a negative pressure mechanism 6 is connected to the bucket lid 1. Here, the negative pressure mechanism 6 includes a vacuum negative pressure pump 61 and a negative pressure pipe 62. The vacuum negative pressure pump 61 is connected to the bucket lid 1 through the negative pressure pipe 62. When the vacuum negative pressure pump 61 is working, it draws air outward to provide a negative pressure environment for the inner bucket 201. Therefore, when the resin undergoes degassing through the multi-stage degassing section 4 and is combined with the negative pressure environment provided by the negative pressure mechanism 6, the bubbles break from the inside due to the pressure difference, thereby achieving the removal of bubbles from the material.
