[0002] In modern industrial production, powder feeding operations play a crucial role in many industries, including chemicals, food, and pharmaceuticals. Taking the chemical industry as an example, the precise and efficient delivery of powders to reaction vessels and other equipment is essential for producing various chemical products, ensuring a stable supply of materials for subsequent chemical reactions. Similarly, the food industry relies on powder feeding devices to accurately deliver raw materials into processing equipment during the production of biscuits, milk powder, and other products.

[0003] Due to the inherent characteristics of powders, such as particle size, moisture content, and viscosity, they easily adhere to the inner wall of the conveying pipe during transport. As the turntable rotates, this powder falls onto the equipment or the ground, causing material waste, polluting the working environment, and potentially leading to equipment malfunctions. Traditional methods for addressing this issue primarily rely on periodic manual cleaning, which increases labor costs and makes it difficult to guarantee the timeliness of manual cleaning.

[0004] Therefore, it is necessary to redesign a rotary powder feeding device to address the above-mentioned problems. Utility Model Content

[0022] 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.

[0023] Reference Figure 1-6 A rotary powder feeding device includes a fixed base 1, a drive shaft 6 fixedly mounted on the upper surface of the fixed base 1, a turntable 7 fixedly mounted on the outer wall of the drive shaft 6, and an mounting plate 3 fixedly mounted on one end of the drive shaft 6. The inner bottom wall of the mounting plate 3 has multiple circumferentially oriented fixing holes 9, each of which is fitted with a conveying pipe 14. These circumferentially oriented fixing holes 9 on the inner bottom wall of the mounting plate 3 are used to fix and install the conveying pipe 14, achieving a multi-channel feeding layout. Driven by the turntable 7, the conveying pipe 14 can be precisely aligned with the feeding tank positions sequentially, realizing automated and continuous feeding of multiple storage tanks.

[0024] Each conveying pipe 14 has a fixed ring 13 fixedly installed at its top end. Each fixed ring 13 has a toothed ring 10 rotatably installed on its outer wall. Each toothed ring 10 has a connecting plate 11 fixedly installed on its upper end face. Each connecting plate 11 has an mounting plate 12 fixedly installed at its bottom end. Each mounting plate 12 has a mounting groove 15 on one side. Each mounting groove 15 has a cleaning device installed inside it.

[0025] Each cleaning device includes two springs 16, which are symmetrically fixedly connected to the inner wall of the mounting groove 15. One end of each spring 16 is fixedly connected to a fixing plate 17, which is slidably connected in the mounting groove 15. A scraper 18 is fixedly connected to one side of the fixing plate 17, and the scraper 18 is in contact with the inner wall of the conveying pipe 14. The scraper 18 is always in close contact with the inner wall of the conveying pipe 14 under the elastic force of the springs 16.

[0026] A mounting bracket 4 is fixedly installed on the inner bottom wall of the mounting plate 3. A motor 5 is fixedly installed on the mounting bracket 4. A gear 8 is fixedly installed on the output shaft of the motor 5, and the gear 8 meshes with multiple gear rings 10 respectively.

[0027] The upper surface of the fixed base 1 is provided with a collection trough 2, which can promptly receive the powder scraped off by the cleaning device and prevent the powder from scattering on the equipment surface or the ground.

[0028] Multiple placement slots are provided on the outer wall of the turntable 7, and the positions of the multiple placement slots correspond to the positions of multiple gears 8.

[0029] A drive motor is fixedly mounted on the upper surface of the fixed base 1, and the output shaft of the drive motor is fixedly connected to the bottom end of the drive shaft 6. After the drive motor is started, it can drive the drive shaft 6 to rotate stably. The turntable 7 fixed on the outer wall of the drive shaft 6 and the mounting plate 3 installed at one end rotate synchronously to realize the circulating feeding of the multi-channel conveying pipe 14.

[0030] When this utility model is in use, when the drive motor starts, the output shaft drives the drive shaft 6 to rotate. Since the turntable 7 is fixedly installed on the outer wall of the drive shaft 6 and the mounting plate 3 is fixedly connected to the top of the drive shaft 6, the turntable 7 and the mounting plate 3 will rotate synchronously with the drive shaft 6 to realize the basic circumferential motion of the entire device. At the same time, the gear 8 of the output shaft of the motor 5 on the mounting bracket 4 inside the mounting plate 3 meshes with multiple gear rings 10. When the motor 5 starts, the gear 8 rotates, driving all the gear rings 10 to rotate synchronously.

[0031] When the gear ring 10 rotates under the drive of the gear 8, the mounting plate 12 rotates accordingly. The spring 16 pushes the scraper 18 to always stick to the inner wall of the conveying pipe 14. The scraper 18 scrapes off the attached powder along the circumference of the inner wall of the conveying pipe 14. The cleaned-up powder is collected through the collection groove 2 of the fixed base 1.

[0032] Multiple fixing holes 9 are formed circumferentially on the inner bottom wall of the mounting plate 3. Each fixing hole 9 is used to fix and install a conveying pipe 14. The top of the conveying pipe 14 is rotatably mounted with a toothed ring 10 via a fixing ring 13. When the turntable 7 drives the mounting plate 3 to rotate, the conveying pipe 14 rotates synchronously with the mounting plate 3, aligning itself with the feeding tank position in sequence. The powder is conveyed from top to bottom to the storage tank through the conveying pipe 14, realizing quantitative or continuous feeding. At the same time, the cleaning device operates synchronously to ensure that the inside of the conveying pipe 14 is unobstructed, ensuring the smooth operation of the feeding tank and the quality of feeding.
