Description

Technical Field

[0001] This utility model relates to the field of hindered amine light stabilizer technology, and in particular to a purification device for hindered amine light stabilizers. Background Technology

[0002] Amine light stabilizers, especially hindered amine light stabilizers, are a class of organic amine compounds with steric hindrance effects, mainly used for anti-aging of polymer materials such as plastics and rubber. They improve the light resistance of materials by capturing free radicals, quenching excited-state oxygen, and decomposing peroxides, thus delaying degradation and aging processes and extending the service life of polymer products. Hindered amine light stabilizers have the ability to decompose hydrogen peroxides, quench excited-state oxygen, and capture free radicals, and their effective groups are recyclable. Therefore, when processing and using hindered amine light stabilizers, purification equipment is required.

[0003] Most purification devices on the market currently produce a large amount of irritating odor during the purification process of hindered amine light stabilizers, making it impossible to purify and discharge them, thus affecting the purification effect of the device. At the same time, when stirring with the mixed solution and stabilizer, the mixed solution and stabilizer tend to adhere to the inner wall, thus affecting the purification effect of the device. Therefore, a purification device for hindered amine light stabilizers is needed to meet people's needs. Utility Model Content

[0022] The purification device for hindered amine light stabilizers of this invention has the following beneficial effects:

[0023] This invention firstly utilizes a design with two sets of activated carbon filters to filter and purify the large amount of irritating odor generated during the purification of amine light stabilizers, thus preventing direct discharge and environmental pollution. Simultaneously, a bolt rod is threaded into the first threaded hole, and through a through-hole and a second vertical rod, the bolt rod rotates to move the extrusion plate up and down on the outer wall of the bolt rod. This allows the extrusion plate to be positioned and fixed, facilitating disassembly and cleaning by operators.

[0024] This invention first starts by starting a drive motor to rotate a drive shaft, which in turn rotates a first mixing rod and a second mixing rod. This rotation of the first and second mixing rods ensures a more uniform mixing of the drug solution, stabilizer, and hindered amine light stabilizer. Simultaneously, the rotation of the first and second mixing rods causes a scraper to rotate, cleaning the drug solution and stabilizer adhering to the inner wall, thus preventing them from sticking to the inner walls of the first and second purification bottles.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein.

By starting the exhaust fan 407, the purified gas inside the purification chamber 402 is discharged, thereby making the gas meet the emission standards.

[0038] Combination Figure 2 , Figure 3 and Figure 4 In an embodiment of this utility model, the purification component 404 includes a first mounting bracket 4041, which is disposed above the baffle 403. A first vertical rod 4042 is fixedly mounted on the top of the first mounting bracket 4041, and a second mounting bracket 4043 is fixedly mounted on the outer wall of the first vertical rod 4042.

[0039] Combination Figure 2 , Figure 3 and Figure 4 In an embodiment of this utility model, the installation and disassembly assembly 4045 includes a bolt rod 40451. The bolt rod 40451 is rotatably mounted on the top of the second mounting bracket 4043 via a bearing. An extrusion plate 40452 is provided on the outer wall of the bolt rod 40451, and a first threaded hole 40453 is provided inside the extrusion plate 40452. The first threaded hole 40453 is threadedly connected to the bolt rod 40451.

The bottom end of the second vertical rod 40455 is fixedly connected to the top of the second mounting bracket 4043. Anti-slip teeth are installed on the bottom end of the extrusion plate 40452. The extrusion plate 40452 is threadedly connected to the bolt rod 40451 via the first threaded hole 40453, thereby causing the bolt rod 40451 to rotate and drive the extrusion plate 40452 to rise and fall on the outer wall of the bolt rod 40451.

[0040] The specific working principle is as follows: when it is necessary to purify the irritating odor generated during the purification of hindered amine light stabilizers, two sets of activated carbon filters 4044 are designed to filter and purify the large amount of irritating odor generated during the purification of the hindered amine light stabilizers, thereby avoiding direct discharge and environmental pollution. At the same time, the bolt rod 40451 is threadedly connected to the first threaded hole 40453, and the through hole 40454 and the second vertical rod 40455 cooperate with each other to make the bolt rod 40451 rotate, thereby driving the extrusion plate 40452 to rise and fall on the outer wall of the bolt rod 40451. This facilitates the positioning and fixing of the activated carbon filter 4044 by the extrusion plate 40452, making it easy for operators to disassemble and clean it.

[0041] Example 2: Refer to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a purification device for hindered amine light stabilizers. When the mixed drug solution and stabilizer are stirred at the same time, the mixed drug solution and stabilizer are easily caused to stick to the inner wall, thereby affecting the purification effect of the purification device. Therefore, a purification device for hindered amine light stabilizers is needed to meet people's needs. The input end of the water pump body 6 is equipped with a water inlet pipe 601, and one end of the water inlet pipe 601 is connected to the discharge pipe 204. The output end of the water pump body 6 is equipped with a water outlet pipe 602 connected to the second purification bottle 301.

[0042] Combination Figure 1 and Figure 5In an embodiment of this utility model, the stirring and mixing assembly 7 includes a drive motor 701, which is fixedly installed at the top of the first purification bottle 201 and the second purification bottle 301. The output end of the drive motor 701 is equipped with a drive shaft 702 that penetrates the interior of the first purification bottle 201 and the second purification bottle 301. The outer wall of the drive shaft 702 is respectively equipped with a first mixing rod 703 and a second mixing rod 704. The outer walls of the first mixing rod 703 and the second mixing rod 704 are both equipped with scrapers 705. By starting the drive motor 701, the drive shaft 702, the first mixing rod 703 and the second mixing rod 704 are driven to rotate simultaneously, thereby making the hindered amine light stabilizer more uniformly mixed by the rotation of the first mixing rod 703 and the second mixing rod 704.

[0043] The specific working principle is as follows: First, the drive motor 701 is started to drive the drive shaft 702 to rotate. The rotation of the drive shaft 702 simultaneously drives the first mixing rod 703 and the second mixing rod 704 to rotate. This rotation of the first mixing rod 703 and the second mixing rod 704 makes the mixed drug solution and stabilizer mixed with the hindered amine light stabilizer more evenly. At the same time, the rotation of the first mixing rod 703 and the second mixing rod 704 drives the scraper 705 to rotate to clean the drug solution and stabilizer adhering to the inner wall, thereby preventing them from adhering to the inner wall of the first purification bottle 201 and the second purification bottle 301.
