Description

Technical Field

[0001] The utility model relates to the technical field of stirring and drying devices, in particular to a stirring and drying device for pearlescent pigments. Background Technique

[0002] Pearlescent pigment is an optical effect pigment. Because it can present a certain metallic luster, it is also called a non-metallic pigment with metallic luster. Pearlescent pigment has the flash effect of metallic pigments and can also produce the soft color of natural pearls. When irradiated by sunlight, it can produce multi-level reflections, and the reflected lights interact with each other to present a soft and eye-catching or colorful luster and color. During the production process of pearlescent pigments, drying is required.

[0003] After retrieval, the Chinese patent number CN paddle (213) 578532U discloses an efficient stirring and drying device for pearlescent pigments, belonging to the technical field of pearlescent pigment production, including a shell. The bottom of the shell is uniformly fixed with support rods, and the top of the support rods is fixed with a conveying cylinder. A spiral conveyor rod is rotatably installed inside the conveying cylinder, and a motor is installed at the middle position of the bottom of the shell. The setting of the conveying cylinder inside the shell of the utility model, used in cooperation with the spiral conveyor rod at the output end of the motor, enables the raw materials to be continuously conveyed through the spiral conveyor rod during the drying process, stirs the raw materials, uniformly dries the raw materials, improves the drying effect, and during the conveying process, used in cooperation with the two funnel covers inside the shell and the two umbrella-shaped covers outside the conveying cylinder, can slow down the dropping rate of the raw materials during the stirring process, increase the contact area with the air inside the shell, and improve the use effect of the device.

[0004] In the above technology, the material only flows to the surface of the static umbrella-shaped cover by gravity. The material flow driven by gravity is slow and unevenly distributed, and it is easy to accumulate into blocks on the surface of the umbrella-shaped cover and cannot be fully spread out, resulting in a significant reduction in the contact area between the material and the heating environment, low drying efficiency, and the situation of "dry outside and wet inside" is likely to occur at the accumulation point, with poor drying uniformity, affecting the color and particle stability of pearlescent pigments; secondly, the static umbrella-shaped cover cannot disperse the material, and the accumulated material is easy to stick and agglomerate, which not only requires additional subsequent processing, but may also block the material flow path and interrupt the processing process, making it difficult to meet the refined requirements of efficient and uniform drying in the production of pearlescent pigments. Content of the Utility Model

[0005] The purpose of this invention is to provide a stirring and drying device for pearlescent pigments, which solves the problems in the above-mentioned technologies. In these technologies, the material relies solely on gravity to flow to the surface of a stationary umbrella-shaped cover. The gravity-driven material flow is slow and unevenly distributed, easily accumulating into clumps on the surface of the umbrella-shaped cover, failing to spread out fully. This results in a significant reduction in the contact area between the material and the heating environment, leading to low drying efficiency. Furthermore, the accumulated material is prone to a "dry outside, wet inside" situation, resulting in poor drying uniformity and affecting the color and particle stability of the pearlescent pigments. Secondly, the stationary umbrella-shaped cover cannot disperse the material, and the accumulated material easily sticks together and clumps, requiring additional subsequent processing and potentially blocking the material flow path, interrupting the processing flow. This makes it difficult to meet the refined requirements of pearlescent pigment production for efficient and uniform drying.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a stirring and drying device for pearlescent pigments, comprising a processing cylinder, and further comprising:

[0024] In a preferred embodiment, the second bevel gear is rotatably disposed on one side of the connecting frame;

[0025] The motor is mounted on one side of the connecting frame, and the outer side of the motor's main shaft is connected to the inner side of the middle part of the second bevel gear.

[0026] The effect is that the second bevel gear is rotatably mounted on one side of the connecting frame and rotates under the drive of the motor, thereby driving the first bevel gear and the third bevel gear to rotate, thus realizing the distribution of power; the motor is mounted on one side of the connecting frame to provide a power source for the entire drive system and ensure that all components can operate normally.

[0027] In a preferred embodiment, a third bevel gear is rotatably disposed on the inner side of the bottom end of the connecting frame, the outer side of the end of the third bevel gear is connected to the outer side of the top end of the connecting cylinder, and the second bevel gear is meshed with the first bevel gear and the third bevel gear respectively.

[0030] The effect is that the baffle plate is fixedly arranged in a ring on the outer side of the first baffle and the second baffle, which can increase the contact area with the pigment, enhance the stirring force, and make the pigment more fully and evenly stirred.

This effectively prevents pigment quality degradation caused by uneven drying. It not only meets the refined stirring and drying requirements of pearlescent pigments but also improves overall processing efficiency, providing stable pigment raw materials for subsequent production.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Example 1:

[0043] Please see Figure 1 - Figure 5 This embodiment provides a stirring drying device for pearlescent pigments that can be dried efficiently. The specific idea is as follows:

[0044] A stirring and drying apparatus for pearlescent pigments includes a processing cylinder 1, a heating plate 101, and a valve 102. The stirring and drying apparatus for pearlescent pigments also includes a first baffle 2 and a connecting member.

[0045] The inner wall of the processing cylinder 1 is equipped with a heating plate 101 for heating. The heat released by the heating plate 101 can heat and dry the pearl pigment material inside the processing cylinder 1. A valve 102 for discharging is installed on the outer side of the bottom of the processing cylinder 1. After the material is stirred and dried, the valve 102 can be opened to facilitate the discharge of the processed material.

[0046] In addition, the interior of the processing cylinder 1 is provided with a first baffle 2 for distributing materials. By blocking and limiting the materials with the first baffle 2, the accumulated materials can be spread out, increasing the contact area between the materials and the heating plate 101 to release heat and improving the drying efficiency.

[0047] In addition, a connector is provided on the inner side of the processing cylinder 1. This connector can serve as a transmission structure and provide installation support for the first baffle 2, ensuring that the first baffle 2 can stably achieve the material spreading function inside the processing cylinder 1.

[0048] As examples, in this embodiment, the connector includes a bottom cylinder 201 and a connecting cylinder 202.

[0049] The bottom inner side of the processing cylinder 1 is fixedly connected to a bottom cylinder 201 that provides support, providing a stable installation base for the subsequent feeding components; the top inner side of the bottom cylinder 201 is rotatably connected to a connecting cylinder 202 that provides feeding, and the middle outer side of the connecting cylinder 202 is fixedly connected to a second baffle 203 that provides shielding. Through the shielding of the second baffle 203, the outflowing material can be spread out, increasing the contact area.

[0050] The inner side of the connecting cylinder 202 is provided with a spiral fan blade 206 for transporting the material vertically upward. The spiral fan blade 206 can transport the pearlescent pigment material in the processing cylinder 1 upward. Combined with the material distribution effect of the first baffle 2, it further improves the uniformity of material contact with heat.

[0051] In addition, the top inner side of the connecting cylinder 202 is provided with a first slot 204 for discharging material, and the middle inner side is provided with a second slot 205 for discharging material. When the spiral fan blade 206 conveys the material upward to the corresponding slot position, the material can be scattered back into the processing cylinder 1 through the first slot 204 and the second slot 205 to form a circulating conveying and extend the material drying time.

[0052] Meanwhile, the bottom cylinder 201 has a sieve hole 214 on the inner side of the end, which serves as a sieve. During the material circulation process, materials that meet the particle size requirements can be preliminarily screened through the sieve hole 214, which not only ensures the quality of the final product, but also avoids the accumulation of unqualified materials that affect the drying efficiency.

[0053] Example 2:

[0054] Please see Figure 1 - Figure 5 This embodiment provides a stirring drying device for pearlescent pigments that can be dried efficiently. The specific idea is as follows:

[0055] A stirring and drying apparatus for pearlescent pigments includes a processing cylinder 1, a heating plate 101, and a valve 102. The stirring and drying apparatus for pearlescent pigments also includes a driving component.

[0056] Among them, a driving component is provided on the inner side of the bottom end of the processing cylinder 1. The driving component is directly connected to the first baffle 2 and is used to drive the first baffle 2 to rotate.

[0057] As examples, in this embodiment, the drive element includes a connecting frame 207 and a first bevel gear 208.

[0058] Among them, the top inner side of the processing cylinder 1 is fixedly connected to the mounting bracket 217 for connecting, the top inner side of the mounting bracket 217 is fixedly connected to the connecting bracket 207 for supporting, the top inner side of the connecting bracket 207 is rotatably connected to the first bevel gear 208 for transmission, one side of the first bevel gear 208 is fixedly connected to the connecting rod shaft 209 for connecting, and the bottom outer side of the connecting rod shaft 209 is fixedly connected to the outer side of one end of the spiral fan blade 206.

[0059] A second bevel gear 210, which serves as a transmission mechanism, is rotatably connected to one side of the connecting frame 207, and a motor 211, which serves as a drive mechanism, is installed thereon. The outer side of the main shaft of the motor 211 is fixedly connected to the inner side of the middle part of the second bevel gear 210. A third bevel gear 212, which serves as a transmission mechanism, is rotatably connected to the inner side of the bottom end of the connecting frame 207, and the outer side of its end is fixedly connected to the outer side of the top end of the connecting cylinder 202. The second bevel gear 210 is meshed with the first bevel gear 208 and the third bevel gear 212 respectively.

[0060] The motor 211 drives the second bevel gear 210 to rotate, which in turn drives the first bevel gear 208 and the third bevel gear 212 to rotate. This causes the connecting rod shaft 209 to drive the spiral fan blade 206 and the third bevel gear 212 to drive the connecting cylinder 202 to rotate synchronously, thus achieving the coordinated action of "spiral conveying + connecting cylinder rotation" and ensuring stable material conveying.

[0061] In addition, a plate-shaped deflector 213 is fixedly connected to the outer side of the first baffle 2 and the second baffle 203. By rotating the first baffle 2 and the second baffle 203 rotating with the connecting cylinder 202, the deflector 213 can actively deflect the material, further breaking up the material agglomeration and expanding the material spreading range.

[0062] The inner side of the mounting frame 217 is fixedly connected with a baffle ring 215 that acts as a blocking device. The baffle ring 215 is located below the first baffle 2 and the second baffle 203. The material falls through the surface of the first baffle 2 and the second baffle 203 to the inner side of the two baffle rings 215. The baffle rings 215 act as a blocking buffer, prolonging the falling time of the material and increasing the contact area with the heating plate 101.

[0063] It should be noted that the motor 211 is covered with a waterproof cover 216, which serves to prevent water vapor from entering the motor 211 during the processing, thus ensuring the stable operation of the motor 211.

[0064] Working principle:

[0065] When using this device, the user can inject the material into the inner side of the processing cylinder 1. At this time, the motor 211 is started, and the motor 211 drives the second bevel gear 210 to rotate. While the second bevel gear 210 rotates, it also drives the first bevel gear 208 and the third bevel gear 212, which are meshed with it, to rotate relative to each other. While the first bevel gear 208 rotates, it drives the connecting rod shaft 209 to rotate, which in turn drives the spiral fan blade 206 to rotate. While the spiral fan blade 206 rotates, it draws the material into the inner side of the connecting cylinder 202 through the bottom cylinder 201 and transports it vertically. The material then flows to the outer side through the first slot 204 and the second slot 205. While the third bevel gear 212 rotates, it drives the connecting cylinder 202 to rotate relative to each other. When the material flows to the surface of the first baffle 2 and the second baffle 203, its rotation can throw the material out, increasing the contact area of ​​the material. The material will also flow to the surface of the baffle ring 215, further increasing the contact area and increasing the heating efficiency.

[0066] This pearlescent pigment stirring and drying device significantly improves the uniformity of pigment stirring and drying efficiency, offering prominent advantages. Firstly, the motor 211 drives multiple components to rotate in tandem, achieving automatic material intake, vertical transport, and orderly conveying. No manual feeding is required, greatly reducing manpower. Simultaneously, the rotating structure keeps the material dynamically stirred during transport, preventing localized clumping and ensuring uniform pigment mixing. Secondly, during transport, the material is thrown onto the surfaces of the first baffle 2, the second baffle 203, and the retaining ring 215 by the rotating components, significantly increasing the contact area between the material and the heating environment. Combined with the synergistic effect of multiple components, this rapidly improves heat transfer efficiency, shortens drying time, and ensures thorough and uniform drying of the pearlescent pigment. This effectively prevents pigment quality degradation caused by uneven drying. It not only meets the refined stirring and drying requirements of pearlescent pigments but also improves overall processing efficiency, providing stable pigment raw materials for subsequent production.

[0067] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
