Description

Technical Field

[0001] This utility model relates to the field of coating processing equipment technology, specifically a vacuum degassing device for polyurethane two-component coatings. Background Technology

[0002] Two-component polyurethane coatings are made by mixing a base agent and a curing agent in a certain proportion. During the mixing process, air is easily entangled and air bubbles are formed. If the air bubbles are not removed and the coating is used directly, defects such as pinholes and shrinkage cavities will appear in the coating, which will seriously affect the appearance quality and performance of the coating.

[0003] However, existing degassing equipment cannot filter the coatings added to the vacuum tank. Impurities in the coatings easily adhere to the vacuum tank, thus affecting the applicability of the equipment.

[0004] To address this issue, we propose a vacuum degassing device for two-component polyurethane coatings. Utility Model Content

[0025] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-4As shown, this utility model provides a technical solution: a vacuum degassing device for a two-component polyurethane coating, including a workbench 1, a vacuum tank 2 installed inside the workbench 1, a discharge pipe 4 connected to the bottom of the vacuum tank 2, a vacuum pump 5 fixedly installed on the upper part of the vacuum tank 2, and a connecting assembly 3 installed inside the vacuum tank 2. The connecting assembly 3 includes a filter mechanism 31 installed on the upper part of the vacuum tank 2. A stirring mechanism 32 is installed inside the vacuum tank 2. A valve is installed at one end of the discharge pipe 4 near the vacuum tank 2. The input end of the vacuum pump 5 is connected to the top of the vacuum tank 2 through an absorption pipe. The filter mechanism 31 includes a feed pipe 31 connected to the upper part of the vacuum tank 2. 1. A valve is provided at one end of the feed pipe 311 near the vacuum tank 2. An installation groove 312 is provided inside the feed pipe 311. An installation frame 313 is inserted into the installation groove 312. A filter plate 314 is fixedly installed inside the installation frame 313. A slot 315 is provided at the top of the installation frame 313. A movable groove 317 is provided inside the feed pipe 311. A movable block 318 is slidably connected to the inner wall of the movable groove 317. An inclined block 319 is fixedly connected to the bottom of the movable block 318. A connecting rod 3110 is fixedly connected to the top of the movable block 318. A spring 3111 is fixedly connected to the inner wall of the movable groove 317. A pull rod is fixedly connected to the outer end of the connecting rod 3110 through the connecting block.

[0028] In this embodiment, the inclined plate block 319 is movably connected to the movable groove 317 and the slot 315. One end of the spring 3111 is fixedly connected to the movable block 318. The outer end of the connecting rod 3110 is movably connected to the movable groove 317. Through the cooperation of the feed pipe 311, the mounting groove 312, the mounting frame 313, the filter plate 314, the slot 315, the sealing ring 316, the movable groove 317, the movable block 318, the inclined plate block 319, the connecting rod 3110, and the spring 3111, the coating added to the vacuum tank 2 can be filtered to prevent impurities from adhering to the vacuum tank 2 and affecting subsequent use. In addition, the mounting frame 313 is easy to disassemble manually, which facilitates manual cleaning of the filter plate 314 and facilitates subsequent use.

[0029] Furthermore, a sealing ring 316 is fixedly connected to the inner wall of the feed pipe 311, and the sealing ring 316 is set in the gap between the mounting groove 312 and the mounting frame 313.

[0030] When material needs to be added, the paint is manually added into the feed pipe 311 and the valve is opened. Then, under the action of the filter plate 314, the paint can be filtered to remove impurities. Furthermore, when the mounting frame 313 needs to be disassembled, simply hold the pull rod and pull the connecting rod 3110 outward. This will cause the movable block 318, which is fixedly connected to the inner end of the connecting rod 3110, to move the inclined plate block 319 upward, allowing the inclined plate block 319 to separate from the slot 315. Then, the mounting frame 313 can be removed outward, making it easier for manual cleaning of the filter plate 314. This prevents the filter holes of the filter plate 314 from becoming clogged, affecting subsequent use, and thus increasing the applicability of the device.

[0031] Example 2

[0032] Based on Example 1, a preferred embodiment of the polyurethane two-component coating vacuum degassing device provided by this utility model is as follows: Figures 1 to 4 As shown: The stirring mechanism 32 includes a motor 321 fixedly mounted on the upper part of the vacuum tank 2 via a bracket. A rotating shaft 322 is fixedly connected to the output end of the motor 321. A conveying blade 323 is fixedly connected to the outer wall of the rotating shaft 322. A mounting rod 324 and a mounting rod 329 are fixedly connected to the outer wall of the rotating shaft 322 respectively. A scraper 326 is fixedly connected to the end of the mounting rod 324 away from the rotating shaft 322. A bubble-piercing needle 325 is fixedly connected to the outer wall of the mounting rod 324. A stirring rod 327 is fixedly connected to one side of the scraper 326. A conveying cylinder 328 is fixedly connected to the end of the stirring rod 327 away from the scraper 326.

[0033] In this embodiment, the rotating shaft 322 is rotatably connected to the vacuum tank 2 via a bearing. Through the cooperation of the motor 321, rotating shaft 322, conveying blade 323, mounting rod 1 324, bubble-piercing needle 325, scraper 326, stirring rod 327, conveying cylinder 328, and mounting rod 2 329, the coating in the vacuum tank 2 can be stirred, and the floating bubbles can be pierced, thereby improving the defoaming effect.

[0034] Furthermore, the end of the mounting rod 329 furthest from the rotating shaft 322 is fixedly connected to the scraper rod 326.

[0035] When the coating is added to the vacuum tank 2, the air inside the vacuum tank 2 is extracted by the vacuum pump 5. At the same time, the motor 321 drives the rotating shaft 322 to rotate. With the cooperation of the first mounting rod 324 and the second mounting rod 329, the scraper 326 fixedly connected to the outer end of the first mounting rod 324 and the second mounting rod 329 can rotate synchronously. This causes the stirring rod 327 fixedly connected to one side of the scraper 326 to drive the conveying cylinder 328 to rotate synchronously, thus stirring the material in the vacuum tank 2. When the rotating shaft 322 rotates, the conveying blades 323 fixedly connected to the outer wall of the rotating shaft 322 can rotate synchronously. With the cooperation of the conveying cylinder 328, the coating at the bottom of the vacuum tank 2 can be conveyed upward to prevent the coating from settling. At the same time, when the first mounting rod 324 rotates, the bubble-piercing needle 325 fixedly connected to the outer wall of the first mounting rod 324 can pierce the upwardly discharged bubbles, thus improving the degassing effect.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
