[0001] This utility model relates to the field of water-based coating technology, and in particular to a negative pressure dehydration device for fast-drying water-based coatings on ABS substrates. Background Technology
[0002] ABS-based fast-drying water-based coatings are coatings specifically designed for coating ABS plastic surfaces. Using water as the dispersion medium, they feature rapid drying and offer numerous advantages such as environmental friendliness and strong adhesion. They are widely used in automotive parts, home appliances, and 3C products. During the production of ABS-based fast-drying water-based coatings, a dehydration process is necessary. Dehydration is a crucial step, aiming to remove moisture from the raw materials to ensure the coating's performance, stability, and the smooth operation of the production process. Dehydration equipment is required for this process.
[0003] However, traditional dehydration devices still have some problems when in use. Traditional extrusion dehydration relies on mechanical pressure (such as filter press), which can easily lead to uneven local pressure and uneven distribution of pigments and fillers in the coating. Therefore, a negative pressure dehydration device for ABS substrate fast-drying water-based coatings is needed to solve the above problems. Utility Model Content

[0025] This utility model embodiment provides a negative pressure dehydration device for fast-drying water-based coatings on ABS substrates, such as... Figures 1-6 As shown, it includes a base 1 and a sealing cover 4;
[0026] A dehydration tank 3 is provided on one side of the top of the base 1. A sealing cover 4 is installed on the top of the dehydration tank 3. An auxiliary structure 5 is provided inside the dehydration tank 3. A negative pressure dehydration structure 2 is provided on the other side of the top of the base 1.
[0027] The auxiliary structure 5 includes a holding tank 502, which is installed inside the dehydration tank 3. A limiting block 504 is installed on the outside of the holding tank 502, and a limiting groove 507 is opened on the inside of the dehydration tank 3. A water outlet 508 is opened at the bottom of the holding tank 502. A handle 506 is installed at the top inside the holding tank 502. A filter layer 501 is installed at the bottom inside the holding tank 502. A water outlet 503 is opened at the bottom inside the holding tank 502. Multiple sets of limiting blocks 504 are provided, and multiple sets of limiting blocks 504 and limiting groove 507 form an insertion structure. Both ends of the handle 506 are inserted into the inside of the holding tank 502 and are hinged to the inside of the holding tank 502. Multiple sets of water outlets 508 are provided, and multiple sets of water outlets 508 are distributed in a ring at the bottom of the holding tank 502.
[0028] In a further preferred embodiment of this utility model, such as Figures 4-6As shown: When dehydrating the quick-drying water-based coating on ABS substrate, the filter layer 501 is placed at the bottom of the container 502. After placement, the coating is poured into the container 502. After pouring, the container 502 is installed into the dehydration tank 3. During installation, the container 502 is positioned by the cooperation of the limiting block 504 and the limiting groove 507, making installation easier and preventing the container 502 from moving around. Furthermore, the handle 506 allows the container 502 to be quickly lifted out after the coating dehydration is complete, making removal more convenient.
[0029] The negative pressure dehydration structure 2 includes a drain tank 201, which is installed on one side of the top of the base 1. A water outlet pipe 202 is installed on one side of the drain tank 201. A first valve 203 is installed at one end of the water outlet pipe 202. A vacuum pump 205 is installed at the rear end of the drain tank 201. A connecting air pipe 206 is installed at one end of the vacuum pump 205.
