[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-4This utility model provides an emulsification device for producing water-based pigment pastes, including an emulsification tank 1. A cone 2 is fixedly connected to the bottom of the emulsification tank 1, and a stirring assembly 3 is provided at the top of the cone 2. The stirring assembly 3 includes a drive shaft 301 rotatably connected to the top of the cone 2. Several connecting blocks 302 are fixedly connected to the side surface of the drive shaft 301 in a linear array. Stirring strips 303 are fixedly connected to both sides of the connecting blocks 302. A scraper frame 304 is rotatably sleeved between the bottom and top of the side surface of the drive shaft 301. A gear groove 305 is opened inside the scraper frame 304, and the bottom of the drive shaft 301 passes through the gear groove 305. Furthermore, a gear 306 is fixedly connected, and several gears 307 are meshed on the side surface of the gear 306. All gears 307 are meshed with gear grooves 305. The gears 307 are rotatably connected to the top of the cone 2. A stirring bar 308 is fixedly connected inside the scraper frame 304. A rotary motor 309 is fixedly installed on the top of the emulsifying tank 1, and the transmission end of the rotary motor 309 is fixedly connected to the stirring bar 303. The scraper frame 304 is a hollow rectangle, and the side surface and bottom of the scraper frame 304 are in contact with the inner wall of the emulsifying tank 1 and the top of the cone 2, respectively. The stirring bar 303 is inclined. The stirring assembly 3 is configured such that by starting the rotary motor 309, its transmission end drives the transmission shaft 301 to rotate. The connecting blocks 302, which are linearly arrayed on the transmission shaft 301, rotate together with it, causing the stirring bars 303 on both sides of the connecting blocks 302 to stir the material in the emulsion tank 1. At the same time, the gear 306 at the bottom of the transmission shaft 301 rotates synchronously. Since the gear 306 meshes with the gear 307 in the gear groove 305 inside the scraper frame 304, and the gear 307 meshes with the gear groove 305, the scraper frame 304 is driven to rotate. The side surface and bottom of the scraper frame 304 scrape the material from the inner wall of the emulsion tank 1 and the top of the cone 2, respectively. At the same time, the stirring bars 308 inside the scraper frame 304 also stir the material.

[0023] The inclined stirring bar 303 of this invention increases the contact area with the material and improves the stirring efficiency; the scraper frame 304 can effectively remove the material adhering to the inner wall of the emulsification tank 1 and the top of the cone 2, avoiding material waste, while ensuring the uniformity of material mixing and reducing stirring dead corners; the stirring bar 308 further enhances the stirring effect, which is conducive to improving the emulsification quality of water-based pigment paste.

[0024] Specifically, such as Figure 2 and Figure 3As shown, a heating assembly 4 is provided on the inner wall of the emulsification tank 1. The heating assembly 4 includes a heating groove 401 formed on the inner wall of the emulsification tank 1. Insulation material 402 is installed inside the heating groove 401, and a heating copper pipe 403 is fixedly installed inside the insulation material 402. When the heating copper pipe 403 is energized, it generates heat, which is transferred to the material inside the emulsification tank 1 through the inner wall, thus heating the material. The insulation material 402, filling the heating groove 401, reduces the heat loss from the heating copper pipe 403 to the outside. The heating copper pipe 403 can precisely control the heating temperature of the material, meeting the temperature requirements during the emulsification of water-based pigment pastes and promoting the emulsification reaction. The insulation material 402 provides good insulation, reducing energy loss, saving energy, and maintaining the stability of the heating environment, ensuring the smooth progress of the emulsification process.

[0025] Specifically, such as Figure 2 As shown, a feed pipe 5 is fixedly connected to the top of the emulsification tank 1. A vacuum pipe 6 is fixedly connected to the outside of the feed pipe 5 and located at the top of the emulsification tank 1. A discharge port 7 is opened at the top of the cone 2, and a discharge pipe 8 is fixedly connected to the bottom of the cone 2. The material enters the emulsification tank 1 through the feed pipe 5; the vacuum pipe 6 can be connected to an external vacuum device to perform a vacuuming operation inside the emulsification tank 1; the emulsified pigment paste enters the discharge pipe 8 through the discharge port 7 at the top of the cone 2 and is discharged through the discharge pipe 8. The feed pipe 5 provides a convenient channel for the material to enter; the vacuuming by the vacuum pipe 6 can remove air from the emulsification tank 1, avoiding the influence of air on the emulsification quality of the water-based pigment paste, such as preventing the formation of bubbles; the structure of the cone 2 facilitates the accumulation of material towards the discharge port 7, and the discharge pipe 8 facilitates the discharge of the emulsified pigment paste, improving production efficiency.

[0026] Specifically, such as Figure 4 As shown, a support assembly 9 is provided at the bottom of the emulsifying tank 1. The support assembly 9 includes a support ring 901 fixedly connected to the lower part of the side surface of the emulsifying tank 1; several support legs 902 are fixedly connected in a circular array at the bottom of the support ring 901, and anti-slip platforms 903 are fixedly connected to the bottom of each support leg 902. The support ring 901 is fixed to the lower part of the side surface of the emulsifying tank 1, providing support for the emulsifying tank 1; the several support legs 902 at the bottom of the support ring 901 support the entire device, lifting the device off the ground; the anti-slip platforms 903 at the bottom of the support legs 902 increase the friction with the ground.

[0027] Working principle and usage process of this utility model:

[0028] When this utility model is in operation, the material enters the emulsification tank 1 through the feed pipe 5, and the vacuum pipe 6 is connected to an external vacuum device to evacuate the inside of the emulsification tank 1 to remove air.

[0029] Then, the rotary motor 309 is started, and its transmission end drives the transmission shaft 301 to rotate. The connecting block 302 on the transmission shaft 301 rotates with it, causing the inclined stirring strips 303 on both sides of the connecting block 302 to stir the material. At the same time, the gear 306 at the bottom of the transmission shaft 301 rotates synchronously. Because the gear 306 meshes with the gear 307 in the gear groove 305 inside the scraper frame 304, and the gear 307 is rotatably connected to the gear groove 305 and the top of the cone 2, the scraper frame 304 is driven to rotate. Its side surface and bottom scrape off the material from the inner wall of the emulsification tank 1 and the top of the cone 2, respectively. The stirring strips 308 inside also participate in the stirring.

[0030] The heating copper pipe 403 in the heating component 4 generates heat when energized, which heats the material through the inner wall of the emulsification tank 1. The heat insulation material 402 in the heating tank 401 reduces heat loss. Finally, the emulsified pigment paste is discharged through the discharge port 7 at the top of the cone 2 into the discharge pipe 8. The support ring 901, support leg 902 and anti-slip table 903 in the support component 9 provide stable support for the entire device.

[0031] 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.
