Description

Technical Field

[0001] This utility model relates to the field of aluminum powder drying technology, specifically to an aluminum hydroxide powder drying device. Background Technology

[0002] In the production and processing chain of aluminum hydroxide powder, the drying process undoubtedly plays a core and crucial role. It not only directly affects the final quality of the product but also has a profound impact on production efficiency and cost control. Traditional hot air dryers, with their simple structure and convenient operation, once dominated the market. However, with the continuous increase in production demands and technological advancements, their limitations in practical applications have gradually become apparent.

[0003] First, low drying efficiency is a major drawback of traditional hot air dryers. Because the hot air is not evenly distributed in the drying chamber, some materials are damaged due to over-drying, while others fail to reach the ideal quality due to insufficient drying. This uneven drying effect not only affects the overall quality of the product, but also leads to low production efficiency.

[0004] Secondly, uneven drying of materials is also a major challenge faced by traditional hot air dryers. When processing large quantities of granular or agglomerated aluminum hydroxide powder, the gaps and accumulation between materials make it difficult for hot air to effectively penetrate the material layer, resulting in inconsistent drying effects. This not only increases the difficulty of subsequent processing but also reduces the market competitiveness of the product.

[0005] Furthermore, high energy consumption is an unavoidable problem for traditional hot air dryers. To compensate for low drying efficiency, traditional hot air dryers often need to increase the hot air temperature and extend the drying time, which undoubtedly greatly increases energy consumption and production costs. In today's context of advocating energy conservation, emission reduction, and green production, this problem is becoming increasingly prominent.

[0006] To overcome the shortcomings of traditional hot air dryers, a series of improved dryers have emerged in the market, such as rotary dryers and vibrating dryers. These dryers have improved drying efficiency and uniformity to some extent, but they also have some problems that urgently need to be solved. Although rotary dryers achieve a more uniform drying effect by constantly tumbling and mixing materials through rotation, they also bring problems such as high energy consumption and complex equipment maintenance. The increase in rotating parts and the increased load lead to a corresponding increase in equipment maintenance costs, putting considerable pressure on the production and operation of enterprises. Vibrating dryers achieve uniform material distribution through vibration, improving drying efficiency. However, the noise and equipment wear generated during vibration cannot be ignored. Long-term vibration not only affects the operating environment and operators, but also leads to loosening and wear of equipment parts, thereby affecting the stability and durability of the equipment.

[0007] Based on this, the present invention designs an aluminum hydroxide powder drying device to solve the above problems. Utility Model Content

[0008] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an aluminum hydroxide powder drying device.

[0011] The drying drum is rotatably mounted; a feed inlet is located on the drying drum for feeding aluminum hydroxide powder; an inner drying drum is located inside the drying drum to hold the aluminum hydroxide powder to be dried; multiple sets of drying mesh plates are installed inside the inner drying drum to allow aluminum hydroxide powder to pass through and evenly disperse the material; multiple sets of scrapers are hinged to the drying mesh plates, and the number of scrapers is equal to that of the drying mesh plates, for scraping away aluminum hydroxide powder that adheres during drying; a steel brush plate is installed on the scraper plate, with steel bristles installed on one side to sweep the mesh of the drying mesh plate; a limiting groove is formed on the inner wall of the inner drying drum, and one side of the scraper slides along the inside of the limiting groove; wherein, the circumference of the limiting groove is half the circumference of the inner drying drum.

[0012] Preferably, the device further includes a fixing frame, which is symmetrically arranged on both sides of the drying cylinder. A motor base is slidably installed between the two fixing frames, and a drive motor is fixed on the motor base. A connecting frame is installed on one side of the drive motor, and one side of the connecting frame is installed on any set of fixing frames.

[0013] Preferably, a first mounting plate is sleeved on one side of the drive motor, a drive plate is rotatably mounted on one side of the first mounting plate, and a fixing plate is fixed on one side of the drying cylinder. The drive plate and the fixing plate are fixedly installed to drive the rotation of the drying cylinder.

[0014] Preferably, one side of the fixing frame on both sides is fixed with multiple sets of limiting wheels, and one side of the multiple sets of limiting wheels abuts against the outer side of the drying cylinder.

[0015] Preferably, a second mounting plate is installed at one end of the fixed frame on both sides, a rotating plate is rotatably installed on one side of the second mounting plate, one side of the drying cylinder and one side of the rotating plate are fixedly installed, and a discharge port is installed on the bottom side of the second mounting plate.

[0016] Preferably, a jacket is provided between the drying cylinder and the inner drying cylinder, and multiple sets of heating wires are fixed inside the jacket along the outer side of the inner drying cylinder to provide the heat required for drying.

[0017] Preferably, the scraper is made of a wear-resistant alloy.

[0018] Compared with the prior art, the advantages of this utility model are as follows:

[0019] 1. This utility model features multiple sets of drying mesh plates, with the mesh size of these plates decreasing progressively. This design allows the aluminum hydroxide powder to be dispersed step by step during the drying process, thereby improving drying efficiency. Simultaneously, because the material is evenly distributed on the drying mesh plates, the uniformity of the drying effect is also ensured.

[0020] 2. This utility model utilizes a combination design of a scraper and a steel brush. The scraper rotates together with the drying mesh to scrape away the adhered aluminum hydroxide powder, effectively preventing powder accumulation and clogging. Meanwhile, the steel bristles on the steel brush further agitate the mesh of the drying mesh, ensuring unobstructed flow and further reducing the possibility of powder agglomeration.

[0021] 3. By designing a limiting groove, this invention restricts the movement trajectory of the scraper, allowing it to scrape evenly along the inner wall of the drying cylinder. This not only improves the scraping effect but also ensures that the scraper will not damage the drying mesh or cause other unnecessary damage during the scraping process.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0033] In some embodiments, please refer to the accompanying drawings. Figures 1-6 A drying device for aluminum hydroxide powder includes: a drying cylinder 1, which is rotatably mounted; a feed inlet 2, which is mounted on the drying cylinder 1 for feeding aluminum hydroxide powder; an inner drying cylinder 6, which is mounted inside the drying cylinder 1 for holding the aluminum hydroxide powder to be dried; multiple sets of drying mesh plates 3, which are installed inside the inner drying cylinder 6 to allow aluminum hydroxide powder to pass through and be evenly dispersed, and whose mesh size gradually decreases to improve drying efficiency; and multiple sets of scrapers 4, which are hinged to the drying mesh plates 3, with the number of scrapers 4 equal to the number of drying mesh plates 3, for scraping aluminum hydroxide powder that adheres during drying. The material is not scraped to prevent powder from clumping and clogging the mesh. A steel brush plate 401 is installed on the scraper plate 4, and steel bristles 402 are installed on one side of it. The steel bristles 402 sweep the mesh of the drying screen plate 3. A limiting groove 5 is opened on the inner wall of the drying inner cylinder 6. One side of the scraper plate 4 slides along the inside of the limiting groove 5. The design of the limiting groove 5 allows the scraper plate 4 to move along the inner wall of the drying inner cylinder 6, thereby achieving uniform scraping of the material on the scraper plate 4. Furthermore, the circumference of the limiting groove 5 is half the circumference of the drying inner cylinder 6. This can reduce the movement distance and energy consumption of the scraper plate 4 while ensuring the scraping effect.

[0034] Fixed frame 9 is symmetrically arranged on both sides of the drying cylinder 1. Motor base 11 is slidably installed between the two fixed frames 9. Drive motor 12 is fixed on the motor base 11. Connecting frame 15 is installed on one side of the drive motor 12. One side of the connecting frame 15 is installed on any set of fixed frames 9.

[0035] A first mounting plate 13 is sleeved on one side of the drive motor 12, and a drive plate 14 is rotatably mounted on one side of the first mounting plate 13. A fixing plate 7 is fixed on one side of the drying cylinder 1. The drive plate 14 and the fixing plate 7 are fixedly installed to drive the rotation of the drying cylinder 1.

[0036] Multiple sets of limiting wheels 10 are fixed on one side of the two fixed frames 9, and one side of the multiple sets of limiting wheels 10 abuts against the outer side of the drying cylinder 1.

[0037] A second mounting plate 18 is installed at one end of the two side mounting brackets 9. A rotating plate 16 is rotatably installed on one side of the second mounting plate 18. One side of the drying cylinder 1 and one side of the rotating plate 16 are fixedly installed. A discharge port 17 is installed on the bottom side of the second mounting plate 18. The discharge port 17 is connected to the inside of the drying inner cylinder 6 for the discharge of aluminum hydroxide powder after drying.

[0038] A jacket is provided between the drying cylinder 1 and the inner drying cylinder 6. Multiple sets of heating wires 8 are fixed along the outer side of the inner drying cylinder 6 inside the jacket to provide the heat required for drying.

[0039] In the above process, the worker places the aluminum hydroxide powder to be dried into the drying inner cylinder 6 through the feed inlet 2. After the aluminum hydroxide powder is filled, the drive motor 12 is started. The output end of the drive motor 12 rotates, driving the drive plate 14 to rotate. Due to the installation between the drive plate 14 and the fixed plate 7, the fixed plate 7 is installed on the drying cylinder 1, thereby driving the drying cylinder 1 to rotate. At this time, the aluminum hydroxide powder placed in the drying inner cylinder 6 rotates. The heat generated by the multiple sets of heating wires 8 dries the aluminum hydroxide powder in the drying inner cylinder 6. Then, during the drying process, the aluminum hydroxide powder falls onto the multiple sets of drying mesh plates 3 in stages for drying. As the mesh size of the drying mesh plate 3 gradually decreases, the dried aluminum hydroxide powder passes through the mesh holes of the drying mesh plate 3 step by step. At this time, due to the phenomenon of aluminum hydroxide powder clumping during the drying process, when the drying mesh plate 3 rotates, it drives the scraper 4 to swing. Due to the limitation of the limiting groove 5, the swing angle of the scraper 4 is less than 90 degrees. At this time, the scraper 4 falls back, and the side of the scraper 4 flattens the clumped aluminum hydroxide powder. Furthermore, one side of the scraper 4 is swept by the steel bristles 402 installed on the steel brush plate 401, which sweeps the flattened aluminum hydroxide powder and makes it pass through the mesh holes of the drying mesh plate 3, thereby avoiding the phenomenon of aluminum hydroxide powder clumping.

[0040] Among them, the diameter of the steel brush bristles 402 gradually decreases with the mesh size of the drying screen plate 3, which avoids the phenomenon of aluminum hydroxide powder clumping at different positions. Finally, the material is discharged from the discharge port 17.

[0041] The scraper 4 is made of wear-resistant alloy, which improves its service life.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
