Technical Field

[0002] As a lightweight metal material, aluminum pellets are widely used in modern industry due to their good fluidity and compressibility. Traditional methods of preparing aluminum pellets often have problems such as low production efficiency and unstable product quality. In order to meet the market's large demand for aluminum pellets and ensure the consistency of product quality, continuous automated aluminum pellet preparation technology has emerged.

[0003] The prior art discloses a high-purity aluminum granule preparation device (CN219130774U), wherein the upper end of the shell is provided with a top cover; a rotary granulating cylinder is installed in a cooling chamber; a plurality of threshing nozzles are arranged on the outer periphery of the rotary granulating cylinder; a cooling gas inlet connected to the cooling chamber is provided on the shell; a feed hopper is installed on the upper end surface of the cylinder cover and is connected to the interior of the rotary granulating cylinder; a heating component is installed on the cylinder cover and the heating end is located inside the rotary granulating cylinder; the circumferential edge of the top end surface of the cooling plate is recessed downward to form an inclined collecting chute, and a discharge hopper connected to the collecting chute is installed on the outer wall of the shell; a driving component is installed in the installation cavity, and penetrates upward through the cooling plate and is transmission-connected to the bottom of the rotary granulating cylinder.

[0004] After searching, it was found that the prior art lacks stirring measures for the aluminum liquid during use, which results in uneven heating of the aluminum liquid during heating, resulting in part of the aluminum liquid being unable to be liquefied, thereby being retained in the granulation barrel, thereby affecting the continuous granulation of the device. Furthermore, the device lacks grinding and refining measures in the preparation of aluminum particles, which results in the prepared aluminum particles being too rough and requiring manual grinding at a later stage, which not only slows down work efficiency but also increases the labor burden of the staff, and is not conducive to the implementation of automation.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0029] Specifically, the outer ring of the conical grinding plate of the grinding disc is an annular filter plate, and the conical grinding plate corresponds to the shape of the conical protrusion. The aluminum particle outlet 17 is located between the circular ring plate and the cylinder 11. The collecting box 12 is located directly below the aluminum particle outlet 17 and is used to receive the aluminum particles after grinding and refinement. When in use, low-temperature nitrogen is introduced into the low-temperature nitrogen channel 13 to keep the cylinder 11 at a low temperature, thereby quickly cooling the aluminum liquid into aluminum particles. When in use, the rotating motor 24 is started to control the rotation of the cylinder. The scraper frame 23 continuously scrapes off the aluminum liquid flowing out from the bottom of the granulation cylinder 15 when rotating. The aluminum liquid is solidified into aluminum particles by low-temperature nitrogen. The cylinder drives the grinding disc 22 to grind the aluminum particles.

The outer wall surface of the granulation cylinder 15 is made of heat-insulating material to prevent low-temperature nitrogen from entering the granulation cylinder 15 and to prevent the heat of the spiral heating tube from reaching the outside of the granulation cylinder 15. Before use, the aluminum powder is poured into the granulation cylinder 15 through the feed pipe 14, and the heater 21 is started for heating. When the aluminum powder is initially melted, the heating tube 21 is heated to a temperature of 100 °C.
