Description

Technical Field

[0001] This utility model relates to the field of heat exchange technology, and in particular to a backup testing mechanism for an acrylic resin water-based dispersion system. Background Technology

[0002] A water-based acrylic resin dispersion testing facility is used for testing purposes. Water-based acrylic resin is a class of acrylic resin organic compounds that use water as the dispersion medium. It is a core material of water-based coatings and is mainly used in architectural, industrial, and civil coatings. Its forms include emulsions, aqueous dispersions, and aqueous solutions, with emulsions and aqueous dispersions being the most common applications. Emulsions have larger particle sizes and are mostly used in latex paint bases; aqueous dispersions have smaller particle sizes and are suitable for high-performance coatings. In testing facilities for water-based acrylic resin dispersions, manual dispensing is often used, resulting in poor precision, easy contamination, high volatility, and easy material adhesion to the reactor walls, leading to uneven mixing, difficult cleaning, and the need to interrupt the reaction for sampling. This is unsafe, interferes with the reaction, and affects the preparation and testing of water-based acrylic resin dispersions. Utility Model Content

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] In view of the problems existing in the above and / or existing backup testing institutions for water-based dispersion systems of acrylic resins, this utility model is proposed.

[0020] 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. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Example 1 Reference Figures 1-5This is the first embodiment of the present invention. This embodiment provides a backup testing mechanism for an aqueous dispersion of acrylic resin. The backup testing mechanism for an aqueous dispersion of acrylic resin includes a reaction vessel 1. A sealing cover 2 is provided on the top of the reaction vessel 1. Several feeding components 3 are provided on the surface of the sealing cover 2. A positioning ring 4 is fixedly installed inside the reaction vessel 1. A mixing component 5 is provided inside the positioning ring 4. An embedding groove is opened on the surface of the reaction vessel 1. A heating component 6 for maintaining a constant temperature is provided inside the embedding groove.

[0023] The mixing component 5 is driven by a servo motor 52, providing stable power and precise speed control. The scraper 54 at the end of the stirring rod 53 scrapes away material adhering to the inner wall of the reactor while stirring. The mixing component 5 is located inside the positioning ring 4 and includes a horizontal plate 51 fixedly installed inside the positioning ring 4. A servo motor 52 is fixedly installed in the middle of the surface of the horizontal plate 51. A stirring rod 53 is fixedly installed at the output end of the servo motor 52. A scraper 54 is fixedly installed at one end of the stirring rod 53.

[0024] After the liquid dosage is poured into the reactor 1, the operator will connect the servo motor 52 to the power supply through the horizontal plate 51. Its output end will drive the stirring rod 53 to rotate. When the stirring rod 53 rotates, it will drive the scraping plate 54 to rotate, scraping off the adsorbed material on the inner wall of the reactor 1, ensuring the uniformity and consistency of the reaction.

[0025] Example 2 Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0026] Specifically, the feeding assembly 3 includes several feeding cylinders 31 fixedly installed on the surface of the closed cover 2.

[0027] Personnel introduce the liquid dosage into the feed cylinder 31, and then close the sealing cover 32. After closing the sealing cover 32, personnel will start the electric push rod 34 through the mounting plate 33. After the electric push rod 34 is started, it will drive the extrusion plate 35 to move downward. When the extrusion plate 35 moves downward, it will extrude the liquid dosage inside the feed cylinder 31, and the liquid dosage will enter the interior of the reactor 1. The step-by-step, quantitative, and controllable addition of multiple raw materials avoids the inaccuracy of manual feeding and the possible introduction of contamination. The top of the feed cylinder is equipped with a sealing cover 32, which together with the sealing cover 2 of the reactor body forms a double sealing structure, effectively preventing the escape of volatile components and the entry of external pollutants.

[0028] Specifically, through grooves are fixedly installed at the four corners of the surface of the mounting plate 33 to facilitate liquid flow.

[0032] The integrated heating element 6, heating ring 61, combined with temperature controller 62 and display screen, enables real-time monitoring, display and precise control of the internal temperature of the reactor.

[0033] Specifically, the size of the embedding groove is adapted to the size of the heating ring 61, and the heating ring 61 heats the interior of the reactor 1 through the embedding groove.

[0034] The heating ring 61 is embedded in the groove of the vessel wall, which realizes uniform circumferential heating, avoids local overheating, and ensures that the reaction system is in the optimal constant temperature state.

[0037] Operators can obtain samples through the guide tube 12 without opening the sealed lid of the reactor, avoiding the dangers that may be caused by open sampling, such as high temperature, high pressure, harmful gases and interference with the reaction process. The filter plate 11 can filter the sample in time, making it convenient to directly observe or detect the particle size of the dispersion, etc., realizing the simultaneous preparation and detection, and improving efficiency.
