[0025] Embodiment 1:

[0026] The present embodiment provides a pigment storage device, as shown in Figures 1-2 which mainly comprises a tank body 1, a plurality of sets of stirring sets 2, a feeding part 3, a discharging part 4 and a drying part 5.

[0027] The tank body 1 is the main container for storing pigment powder, and the plurality of sets of stirring sets 2 and the drying part 5 are arranged in the inner cavity 101 of the tank body 1, which cooperate to carry out the drying work of the pigment powder; the feeding part 3 is arranged at the top of the tank body 1, for inputting newly added pigment powder into the inner cavity 101, and the discharging part 4 is arranged at the bottom of the tank body 1, for outputting the pigment powder in the inner cavity 101 to the outside.

[0028] Each of the plurality of sets of stirring sets 2 comprises a driving shaft 201 vertically arranged in the inner cavity 101 of the tank body 1 and a stirring blade 202 arranged on the driving shaft 201, wherein the stirring blade 202 can drive the pigment powder in its vicinity which is in contact with the stirring blade 202 to move along the vertical material conveying driving direction, and the material conveying driving directions of the adjacent two sets of stirring sets 2 are opposite. Preferably, in the present embodiment, as shown in Figure 1 three sets of stirring sets 2 are arranged inside the tank body 1, one of which is a first stirring set 2-1 vertically arranged at the center point, and the other two are second stirring sets 2-2 arranged on both sides of the first stirring set 2-1. Taking the above arrangement as an example, the first stirring set 2-1 will drive the pigment powder around it to flow upwards, while the second stirring set 2-2 around it will drive the pigment powder around it to flow downwards, and so on Figure 1As shown, a vertical circulation of pigment is formed between two adjacent sets of agitator kits 2. When new pigment is added from the top through the feeding section 3, it will first be placed on the top layer of pigment powder, and then directly participate in the circulation and quickly enter the middle or even bottom layer of pigment powder. At the same time, since the new pigment powder participating in the circulation can move quickly in the inner cavity 101 along the circulation path L1, the probability of the newly added pigment powder passing by or approaching the drying section 5 set in the inner cavity 101 during the movement is greatly increased. This makes the drying section 5 more likely to dry the newly added pigment powder as quickly as possible, ensuring that all pigment powder stored in the tank 1 can be dried quickly and meet the requirements of indicators such as moisture content required for long-term storage.

[0029] Preferably, such as Figure 1 As shown, a first driving device 203 is provided on the top of the tank 1. This first driving device 203 is simultaneously driven and connected to three sets of stirring components 2. In this embodiment, the first driving device 203 is directly connected to the first stirring component 2-1, and simultaneously connected to two sets of second stirring components 2-2 via rotating components. Meanwhile, as... Figure 1 As shown, the rotation direction of the stirring blade 202 in the first stirring kit 2-1 is opposite to that of the stirring blade 202 in the second stirring kit 2-2. Therefore, taking the existing arrangement as an example, the first driving device 203 can simultaneously drive the drive shafts 201 in all three stirring kits 2 to rotate clockwise. However, since the rotation directions of the stirring blades 202 are set in opposite directions, the first stirring kit 2-1 can still drive the surrounding pigment powder to flow upwards, while the surrounding second stirring kits 2-2 will drive the surrounding pigment powder to flow downwards, so that the circulation of pigment powder can continue. This structure saves the total number of driving devices required, facilitates the output control of driving force, and reduces the manufacturing cost of pigment storage equipment. On the other hand, the first driving device 203 ensures that the stirring and conveying efficiency of multiple stirring kits 2 is consistent, that is, the total amount of pigment transported upwards and downwards per unit time is consistent, avoiding the accumulation of pigment due to excessive transport in either direction, and ensuring the normal operation of the circulation.

[0030] Preferably, the drying section 5 is located at the bottom of the inner cavity 101. For example... Figure 1 As shown, the pigment entering this pigment storage device can circulate vertically. Therefore, the drying section 5 at the bottom increases the probability that the pigment in circulation will come into contact with or be close to the drying section 5, thereby enabling the pigment to dry quickly.

[0031] Preferably, such as Figure 1As shown, the heat transfer surface 501 of the drying part 5 covers the bottom surface of the inner cavity 101, which ensures that the drying part 5 has sufficient working area and further increases the probability of the pigment coming into contact with or close to the drying part 5 during the flow process.

[0032] Preferably, the feeding opening 301 in the feeding part 3 is arranged between the two adjacent groups of stirring sets 2, as shown in Figure 1 As shown, the main area of the pigment circulating in the vertical direction is concentrated between the two groups of stirring sets 2, so when the feeding opening 301 is arranged at the top between the two groups of stirring sets 2, the newly added pigment can quickly participate in the circulation of the pigment and be quickly dried.

[0033] Preferably, as shown in Figure 2 As shown, the side wall of the tank 1 is provided with an observation window 7. This structure facilitates the user to observe the total amount of pigment in the tank 1, so as to estimate whether new pigment needs to be added, etc.

[0034] Preferably, as shown in Figures 1-2 As shown, the feeding part 3 comprises a feeding opening 301 arranged at the top of the tank 1, a feeding pipe 302 arranged at the top of the tank 1, and a sealing cover 303 covering the feeding pipe 302; the discharging part 4 comprises a discharging opening 401 arranged at the side of the tank 1, a discharging pipe 402 arranged at the side of the tank 1, and a quantity control valve 403 arranged in the discharging pipe 402, and the discharging opening 401 and the discharging pipe 402 are close to the bottom of the tank 1. This structure ensures the sealing of the tank 1 as a whole, and makes it difficult for external air to enter the tank 1 during feeding and discharging, thereby reducing the possibility of the pigment being dampened and condensed.

[0035] Embodiment 2:

[0036] The difference between this embodiment and Embodiment 1 is that in this embodiment, the inner cavity 101 is further provided with a scraper set 6, which comprises a scraper 601 and a second driving device 602, so that the scraper 601 slides along the inner wall 102 of the tank 1. During the circulation of the pigment, it may be adhered to the inner wall 102 in the inner cavity 101, so that the second driving device 602 drives the scraper 601 to scrape off the pigment powder on the inner wall 102, so as to re-enter the circulation. The scraper set 6 can adopt a structure that drives the scraper 601 to slide in the vertical direction relative to the inner wall 102 to scrape off the pigment, or a structure that drives the scraper 601 to rotate around the center of the inner cavity 101 to scrape off the pigment, etc.

[0037] Preferably, as shown in Figure 1 and Figure 3As shown, the scraper set 6 contains a driving ring block 603, which is movably installed on the top of the inner cavity 101, and in the embodiment, a driving ring block 603 is arranged on the top of the inner cavity 101. Figure 1 and Figure 3 As shown, a supporting member 103 is arranged on the top of the inner cavity 101, which extends downward from the inner ring of the driving ring block 603 and supports the driving ring block 603; the bottom of the driving ring block 603 is connected with the scraper 601. Meanwhile, the second driving device 602 is arranged on the top of the tank 1 and is drivingly connected with the driving ring block 603, and in the embodiment, a driving slot 603-1 is arranged on the top of the driving ring block 603, a gear rack 603-2 is arranged in the slot, and the bottom of the second driving device 602 is provided with a gear 602-1, which is engaged with the gear rack 603-2 in the driving slot 603-1, so that the driving ring block 603 rotates around the center point of the tank 1 and drives the scraper 601 arranged on the bottom to slide relative to the inner wall 102, thereby achieving the effect of scraping the paint.
