Description

Technical Field

[0001] The utility model belongs to the technical field of pigment production, and in particular relates to a pearlescent pigment drying device. Background Art

[0002] Pearlescent pigment is a kind of optical effect pigment. Because it can present a certain metallic luster, it is also called non-metallic pigment with metallic luster. Pearlescent pigment has the glittering effect of metallic pigment and can produce the soft color of natural pearl. When exposed to sunlight, it can produce multi-level reflection. The interaction of reflected light presents soft and dazzling or colorful luster and color.

[0003] The traditional pearlescent pigment drying production process is to place the filtered and washed filter cake on a drying tray and then dry it by air blast. Due to the high moisture content and thick filter cake, the drying efficiency is often low and the energy consumption is high, which leads to uneven drying and affects the next production process and product quality. Therefore, most of the current methods are to crush the filter cake before drying, and the crushed pearlescent pigment needs to be stirred during drying to ensure the drying effect and efficiency.

[0004] However, when the existing drying device is drying a batch of pearlescent pigments, the following problems are prone to occur: the loose pearlescent pigments that have been dried cannot be discharged, and will continue to be dried along with the undried agglomerated pearlescent pigments until all the pearlescent pigments are dried and can be discharged. This will cause some pearlescent pigments to waste energy due to too long drying time, thereby increasing the cost of the product. Utility Model Content

[0005] The purpose of the utility model is to provide a pearlescent pigment drying device, which is used to solve the problem that the existing drying device cannot discharge the pearlescent pigment that has been dried during the drying process.

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or in the specification, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "back", etc., are only referenced to the directions of the drawings and are not used to limit the scope of protection of the present invention.

[0032] like Figures 1 to 3 As shown, a pearlescent pigment drying device of the utility model comprises a baking cylinder 1, a baking assembly 2 and a filtering assembly 3 arranged in the baking cylinder 1. The baking cylinder 1 is provided with an inlet 11 and an outlet 12. Block pearlescent pigments to be baked enter from the inlet 11, are baked and loosened under the action of the filtering assembly 3 and the baking assembly 2, and are discharged from the outlet 12. The filtering assembly 3 comprises a rotating shaft 32 and a filter bucket 31, and the filter bucket 31 is provided with a filtering hole 311. The filter bucket 31 is fixed on the rotating shaft 32, and a driving member 13 for driving the rotating shaft 32 to move is provided at one end of the rotating shaft 32. The baking assembly 2 is used to bake the pearlescent pigment on the filter bucket 31. While the block-shaped pearlescent pigment in the filter bucket 31 is passing through the baking component 2, the driving member 13 can drive the filter bucket 31 and the rotating shaft 32 to move, thereby driving the block-shaped pearlescent pigment to vibrate. The powdered pearlescent pigment that has been baked can pass through the filter hole 311 and be discharged from the discharge port. The block-shaped pearlescent pigment that has not been baked continues to be baked in the filter bucket 31 until it is completely dried and powdered.

[0033] Preferably, there are multiple filter buckets 31, and multiple groups of baking components 2 are also provided. Each group of baking components 2 is used to heat the matching filter buckets 31 respectively. From top to bottom. The diameter of the filter hole 311 on each filter bucket 31 decreases step by step. The heat emitted from the baking component 2 to the filter bucket 31 also decreases step by step. In this way, according to the size of the pearlescent pigment agglomerate, it can be heated using baking components 2 with different heating capabilities, which is conducive to accelerating the drying and discharge of the pearlescent pigment.

[0034] The method for controlling the heat emitted from the baking assembly 2 to the filter bucket 31 from top to bottom to be gradually reduced may be: adjusting by changing the distance between the baking assembly 2 and the filter bucket 31. Specifically, from top to bottom, the distance between the baking assembly 2 and the corresponding filter bucket 31 increases step by step. For example, the distance between the top baking assembly 2 and the top filter bucket 31 is 10 cm, and the distance between the bottom baking assembly 2 and the bottom filter bucket 31 is 30 cm. In this way, when each group of baking assemblies 2 is the same, the baking efficiency is adjusted by adjusting the baking distance.

[0035] Of course, the method of controlling the heat emitted from the baking assembly 2 to the filter bucket 31 from top to bottom to gradually reduce can also be: each group of baking assemblies 2 includes a plurality of heating rods 21, and the number of heating rods 21 on each group of baking assemblies 2 decreases from top to bottom. For example, the number of heating rods 21 at the top for baking large-sized pearlescent pigment agglomerates is set to 8, and the number of heating rods 21 at the bottom for baking small-sized pearlescent pigment agglomerates is set to 4. In actual use, the baking efficiency of the heating assembly can also be adjusted by adjusting the heating power of each heating rod 21.

[0036] Preferably, each group of baking components 2 can be slidably arranged on the inner wall of the baking cylinder 1, so that the position of the baking components 2 can be selectively adjusted to adapt to various drying conditions in the actual production process.

[0037] The driving member 13 is used to drive the rotating shaft 32 and the filter bucket 31 to move. The movement here can be vibration or rotation. The pearlescent pigment agglomerates on the filter bucket 31 can continuously collide with each other and the filter bucket 31 during the vibration or rotation of the filter bucket 31, becoming loose, which helps to accelerate the drying process.

[0038] In this way, the driving member 13 may include a motor. One end of the rotating shaft 32 is connected to the output end of the motor, and the motor is used to drive the rotating shaft 32 and the filter bucket 31 to rotate. In the present application, the filter bucket 31 is provided to prevent the pearlescent pigment from being gathered around the filter bucket 31 due to the centrifugal force during the rotation process and being difficult to discharge. Of course, the driving member 13 may also include an exciter. The exciter is used to drive the rotating shaft 32 and the filter bucket 31 to vibrate.

[0039] In the present application, the device also includes a vibration component. The vibration component is used to drive the rotating shaft 32 to vibrate during the rotation process. Specifically, the rotating shaft 32 is splined to the output end, and the vibration component includes a mounting rod 41 and a vibration plate 42. The mounting rod 41 is fixed on the inner wall of the baking cylinder 1, and the vibration plate 42 is fixed below the rotating shaft 32 through the mounting rod 41. A first protrusion 43 is provided on the vibration plate 42, and a second protrusion 44 matching the first protrusion 43 is provided on the rotating shaft 32. When the first protrusion 43 rotates to contact the second protrusion 44, the first protrusion 43 can lift the second protrusion 44; when the first protrusion 43 rotates to not contact the second protrusion 44, the second protrusion 44 falls, and the rotating shaft 32 is driven to rotate and vibrate in the reciprocating process.

[0040] In the present application, the pearlescent pigment drying device further includes a bracket 4 for supporting the baking cylinder 1 .

[0041] The above is a detailed introduction to a pearlescent pigment drying device provided by the utility model. The description of the specific embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
