Description

Technical Field

[0001] The utility model relates to the field of organic pigment storage equipment, in particular to an organic pigment storage device. Background Art

[0002] Organic pigments refer to insoluble organic pigments, which are usually added to the substrate in a highly dispersed state to color the substrate. The fundamental difference between organic pigments and dyes is that dyes can be dissolved in the dyeing medium used, while pigments are insoluble in neither the medium in which they are used nor the substrate to be colored.

[0003] Organic pigments have the advantages of bright colors, strong tinting power, and non-toxicity. They are widely used in the original pulp coloring of inks, paints, coatings, synthetic fibers, as well as fabric coating printing, plastics, rubber, leather coloring and other industries, and the application scenarios are extremely wide. However, some varieties of organic pigments are often not as light-resistant, heat-resistant, solvent-resistant and migration-resistant as inorganic pigments, which is also its shortcoming. Therefore, in order to ensure the quality of organic pigments, special storage equipment is required during storage, such as the Chinese patent with application number: CN202321853282.0, which specifically states: An organic pigment storage device, including a device housing, a drive motor and a desiccant, a drive motor is installed inside the upper end of the sealing cover, the output end of the drive motor passes through the motor support plate, the output end of the drive motor is connected to a transmission shaft through a coupling, and the lower end of the transmission shaft is connected to a desiccant filling device, the desiccant filling device is filled with desiccant, and the side of the desiccant filling device is installed with a stirring blade, and the stirring blade is a threaded stirring blade. The above-mentioned device is a storage device for organic pigments, which can prevent the organic pigments from condensing by stirring. However, when stirring in the above-mentioned patent, the organic pigments are easily oxidized by oxygen in the air, resulting in discoloration and hardening. At the same time, the above-mentioned patent cannot provide a stable, low-temperature storage environment for the organic pigments. Utility Model Content

[0006] The sealing cover includes an arc-shaped cover at the top and a sealing blind plate at the bottom. A power box electrically connected to an external control device is arranged in the cavity inside the arc-shaped cover and the sealing blind plate. The power box is connected to a miniature vacuum pump. One end of the miniature vacuum pump is connected to the interior of the storage tank through an inner connecting pipe of the tank, and the other end of the miniature vacuum pump is connected to the air through an outer connecting pipe of the tank.

[0022] See also Figure 2 A plurality of heat exchange fins 11 are arranged on the heat exchange tube 8. Such an arrangement can increase the contact area between the heat exchange tube 8 and the organic pigment through the heat exchange fins 11, thereby improving the heat exchange efficiency.

[0023] See also Figure 1 and Figure 2 A flow rate valve 5 is installed on the liquid inlet pipe 4, and the flow rate valve 5 is a solenoid valve. This arrangement makes it easy to adjust and control the input flow rate of the coolant through the flow rate valve 5 at any time, thereby maintaining a constant low-temperature storage environment in the storage tank 1.

[0024] See also Figure 3 A drying box 707 is provided below the sealing blind plate 702, and color-changing silica gel is contained inside the drying box 707. This arrangement facilitates the use of the drying box 707 to absorb the residual water vapor in the storage tank 1 to prevent moisture from causing hardening of the organic pigment.

[0025] See also Figure 3 A barometer 708 is provided below the sealing blind plate 702, and the barometer 708 is electrically connected to the power box 703.
