Description

Technical Field

[0001] The invention relates to the technical field of pigment dehumidification equipment, in particular to a dehumidification device for preparing organic pigments. Background Art

[0002] Organic pigments are a type of colored organic compounds that are insoluble in water and organic solvents. They have the characteristics of bright colors and strong tinting power, and are widely used in many fields. The crude pigments after synthesis need to undergo a series of post-processing steps, such as filtration, washing, drying, crushing, etc., to improve the purity, particle size distribution and application performance of the pigments. In addition, organic pigments may be affected by humidity during production, storage and use, so appropriate dehumidification methods are needed to ensure their quality and performance. Although the existing heating dehumidification method has a certain dehumidification effect when processing organic pigments, it also has some disadvantages. Organic pigments are usually composed of complex organic molecules. 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 decomposing the pigment or affecting its performance. In particular, uneven heating causes some pigments to overheat. Summary of the invention

[0033] Working principle: 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; 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; Step (3): Then, by driving the fan 32 and the heating box 31 in the air supply structure 3, the fan 32 supplies air into the heating box 31, and the air is heated by the heating box 31, and then the air is heated up and enters the dehumidification box 22 from the air supply pipe 33, and the hot air is effectively blown downward by the wind shield 34; Step (4): The motor 42 is driven to rotate the shaft tube 41 through the pulley 43 and the rotating belt, thereby driving the first stirring plate 45, the first stirring grid 46, the second stirring grid 48, the second stirring plate 47 and the third stirring plate 49. As the stirring plate 46 rotates, the pigment blocks are driven to rotate by the second stirring plate 47 and the third stirring plate 49, and the pigment passing through the first stirring grid 46 is driven to rotate by the first stirring plate 45, thereby driving the pigment to be stirred and to be lifted and lowered by force, so as to be fully in contact with the hot air. Step (5): With the rotation and stirring, the pigment clumps are broken up by force, and the second hydraulic cylinder 53 in the breaking component 5 can be driven to extend and retract at the same time. The reciprocating extension and retraction of the second hydraulic cylinder 53 drives the telescopic rod 52 to move left and right in the shaft tube 41 under the limiting action of the bearing round seat 51, and then, with the help of the movably arranged connecting rod, the support arm 54 is driven to flip and swing back and forth under force, so as to drive the push plate 55 to move back and forth relative to the side wall of the first stirring grid 46, so as to push and force the pigment to break up. The maximum flip angle of the support arm 54 can also be controlled to cause the push plate 55 to contact with the first stirring grid 46 to generate clamping force and vibration to prevent blockage. Step (6): After the hot air blows the pigment to heat up and dehumidify it, the wind will drive the moisture to pass through the filter 35, shielding the pigment through the filter 35, and the moisture is discharged from the exhaust port; after the dehumidification process, the first hydraulic cylinder 27 can be driven to contract, driving the lower seat 24 located on the dehumidification box 22 to flip downward, one end of the lower seat 24 opens the lower wall of the dehumidification box 22, and the other end of the lower seat 24 opens the left side wall of the dehumidification box 22, that is, the left side of the second stirring grid 48, which can be effectively cleaned and discharged.
