Description

Technical Field

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

[0002] Aluminum powder, as an important industrial raw material, is widely used in metallic pigments, refractory materials, rocket propellants, and 3D printing. Due to its large specific surface area and high reactivity, aluminum powder is highly susceptible to moisture absorption and oxidation, leading to decreased purity, deterioration of combustion performance, and even dust explosions. Therefore, aluminum powder must be thoroughly dried before preparation, storage, and use. Existing aluminum powder drying and storage equipment relies on ordinary stirring and heating, but the hot air cannot completely penetrate the aluminum powder pile, or requires a significant amount of time for complete heating, thus reducing efficiency and drying effectiveness.

[0003] Therefore, to address the aforementioned problems, a targeted aluminum powder drying and collection device is proposed. Utility Model Content

[0004] This invention addresses the problems mentioned above by designing an aluminum powder drying and collecting device. This device can turn the aluminum powder inside the container back and forth, so that the aluminum powder at the bottom can also be turned to the top, and the aluminum powder in all positions can be turned back and forth, thereby improving the heating effect of the aluminum powder and improving the drying efficiency.

[0005] To achieve the above objectives, this utility model provides an aluminum powder drying and collecting device, comprising: an outer tank, a conveying device, an electric heating plate, and a hot air device. The outer tank has a perforated plate and a conical plate arranged from bottom to top inside. The perforated plate is connected to the conical plate via a powder control valve. The outer tank consists of a drying zone, a ventilation zone, and a storage zone from top to bottom. The conveying device, used to circulate and transport material from the bottom to the upper part, is vertically arranged within the drying zone. The electric heating plate is fixedly arranged at the bottom of the conical plate. The hot air device is arranged at the top of the drying zone. The top and bottom of the outer tank are respectively provided with an inlet and an outlet.

[0006] In this manner, aluminum powder enters the drying zone through the feed inlet. Inside the drying zone, the heating plate at the bottom of the conical plate heats and dries the aluminum powder. The conveying device transports the aluminum powder from the bottom to the top, where it sinks and is further dried by the hot air device as it falls, ensuring that all the aluminum powder is evenly heated and dried. After drying, the powder falls into the storage area below via an electronically controlled powder valve.

[0007] Furthermore, the conveying device includes: a screw conveyor, a sleeve, a fixing rod, and a motor. The motor is located at the top of the outer tank, the screw conveyor is placed inside the outer tank and connected to the motor, the sleeve is sleeved outside the screw conveyor, and the sleeve is fixedly connected to the inner wall of the outer tank through the fixing rod.

[0008] Using the above method, aluminum powder can be transported from the bottom to the top via a screw conveyor and sleeve.

[0009] Furthermore, the hot air device includes: a hot air duct, a ventilation hole, and a hot air blower. The hot air duct is fixedly connected to the inner wall of the top of the outer tank. The interior of the hot air duct has a hollow structure, and the ventilation hole is provided on the inner surface. The hot air blower is located on the top of the outer tank and connected to the hot air duct.

[0010] Furthermore, the sleeve is also provided with a skirt, which is fixedly connected to the top of the sleeve.

[0011] Furthermore, the conveying device also includes a stirring section, which is a plate-shaped structure. The stirring section is fixedly connected to the lower part of the screw conveyor and is parallel to the inner surface of the conical plate.

[0012] In this way, the stirring section can stir the aluminum powder at the bottom, so that the aluminum powder can be evenly distributed at the bottom.

[0013] Furthermore, it also includes a scraping device, which is located at the bottom of the storage area and below the powder control valve.

[0014] Furthermore, the scraping device includes: a driver, a scraper, a cone, and a support platform. The driver is disposed at the bottom of the outer tank. The scraper is fixedly connected to both sides of the support platform. The support platform is connected to the output end of the driver. The cone is fixedly disposed on the upper part of the support platform.

[0015] Furthermore, it also includes a sealing device, wherein a filter screen is provided on the ventilation area of ​​the outer tank, and the sealing device is located on the side of the outer tank.

[0016] Furthermore, the sealing device includes a push-pull plate and a limiting baffle. The limiting baffle has a right-angle structure. The limiting baffle is fixedly connected to the outer tank on both sides of the filter screen. The push-pull plate is slidably connected between the limiting baffle and the outer tank.
