[0002] Organic pigments are a class of colored organic compounds that are insoluble in water and organic solvents, and have characteristics such as bright colors and strong coloring power, and are widely used in many fields; the crude pigments after synthesis need to go through a series of post-treatment processes, such as filtration, washing, drying, pulverization, etc., to improve the purity, particle size distribution and application performance of the pigments; and during the production, storage and use of organic pigments, they may be affected by humidity, so appropriate dehumidification methods need to be adopted to ensure their quality and performance; the existing heating dehumidification method has certain dehumidification effects when treating organic pigments, but there are also some disadvantages; organic pigments are usually composed of complex organic molecules, and different organic pigments have different thermal stabilities. When the heating temperature exceeds their tolerance range, the chemical bonds inside the organic pigment molecules may break, resulting in changes in the molecular structure, thereby causing the pigment to decompose or affecting its performance; especially uneven heating leads to overheating of some pigments.

As the grid rotates, with the help of the first stirring plate and the second stirring plate, the pigments are driven to stir and filter quickly, effectively breaking up the agglomerated pigments, fully making the pigments flow and being evenly heated, and the hot air drives the moisture to evaporate and be discharged; moreover, the arranged dispersing component can push the pigments during rotation, promote the flow and heating of the pigments, and at the same time can apply force to the pigments to break them up or impact the stirring grid to prevent blockage. To sum up, the present invention has the following effects:

[0013] 1. The first stirring plate and the second stirring plate are respectively arranged on the inner and outer sides of the first stirring grid correspondingly. As the grid rotates, they can continuously stir the pigments, so that the agglomerated pigments are subjected to a driving force and are thus more easily broken up.

[0014] 2. By driving the pigments to stir quickly by the first stirring plate and the second stirring plate and filtering through the first stirring grid, the pigments can flow fully; in a hot air environment, the flowing pigments can contact the hot air more evenly, avoiding local overheating or insufficient heating, so as to ensure that the pigments are evenly heated as a whole.

[0015] 3. During the process of pushing the rotating pigments, the dispersing component can not only promote the flow and heating of the pigments, but also apply force to break up the pigments, avoiding the accumulation and caking of pigments at the stirring grid, thus preventing the occurrence of blockage. Since the pigments can flow fully and be evenly heated, and the stirring grid is not easily blocked, the whole device can process the pigments more smoothly during operation, reducing the time for shutdown cleaning or adjustment caused by blockage or uneven heating, thereby improving the operation efficiency of the device.

[0016] 4. Through the full flow and even heating of the pigments, the hot air can better contact the pigments, accelerating the evaporation and discharge of moisture; the pushing and breaking-up effects of the dispersing component on the pigments also further increase the contact area and contact frequency between the pigments and the hot air, thereby improving the dehumidification effect.

[0034] Working principle:

[0035] Step (1): First, the base 1 is stably supported, and after the device is powered on, the pigment is put into the dehumidification box 22 through the feed slot 25 in the main structure 2, and after the pigment is put into the dehumidification box 22, the feed slot 25 is closed by the sealing plate 26; after the pigment enters the dehumidification box 22, it falls to the bottom and is located on the first stirring frame and the second stirring frame in the stirring assembly 4;

[0036] Step (2): If there is no agglomerated pigment, the pigment will pass through the first stirring grid 46 and be located between the first stirring plates 45 or pass through the first stirring grid 46 and fall onto the lower row seat 24;

[0037] Step (3): Further, by driving the fan 32 and the heating box 31 in the air supply structure 3, the air is supplied into the heating box 31 by the fan 32, and the air is heated by the internal temperature rise of the heating box 31 and then enters the dehumidification box 22 from the air supply pipe 33, and the hot air is effectively blown downward by means of the wind deflector seat 34;

[0038] Step (4): At the same time, the driving motor 42 drives the shaft tube 41 to rotate through the belt pulley 43 and the rotating belt, so as to drive the first stirring plate 45, the first stirring wire mesh frame 46, the second stirring wire mesh frame 48, the second stirring plate 47 and the third stirring plate 49. Along with the rotation, the lumped pigments are driven to rotate by the second stirring plate 47 and the third stirring plate 49, and the pigments passing through the first stirring wire mesh frame 46 are driven to rotate by the first stirring plate 45, thereby driving the pigments to be stirred and to rise and fall under force, and fully contacting with the hot air;

[0039] Step (5): Along with the rotation, the stirring will apply force to break up the lumped pigments. At the same time, the second hydraulic cylinder 53 in the dispersion assembly 5 can be driven to expand and contract. The telescopic rod 52 is driven to move left and right in the shaft tube 41 under the limiting action of the bearing circular seat 51 by the reciprocating expansion and contraction of the second hydraulic cylinder 53. Then, by means of the movably arranged connecting rod, the supporting arm 54 is driven to reciprocally turn and swing under force, so as to drive the push plate 55 to reciprocally move relative to the side wall of the first stirring wire mesh frame 46, push and apply force to break up the pigments. The maximum turning angle of the supporting arm 54 can also be controlled, so that the push plate 55 contacts the first stirring wire mesh frame 46 to generate clamping force and vibration to prevent blockage;

[0040] Step (6): After the hot air blows the pigments to rise in temperature and dehumidify, the air will drive the moisture to pass through the filter screen 35. The filter screen 35 blocks the pigments, and the moisture is discharged from the air outlet. After the dehumidification process, the first hydraulic cylinder 27 can be driven to contract, driving the lower discharge seat 24 to turn downward on the dehumidification box 22. One end of the lower discharge seat 24 opens the lower wall of the dehumidification box 22, and the other end of the lower discharge seat 24 opens the left side wall of the dehumidification box 22, that is, the left side of the second stirring wire mesh frame 48, so as to effectively clean and discharge.
