Description

Technical Field

[0001] This utility model relates to the field of asphalt aggregate processing technology, specifically a hot drying mixing barrel for mixed powders. Background Technology

[0002] In powder processing, uniform mixing is one of the key factors affecting product quality. Powder mixing equipment typically uses simple stirring methods, which are difficult to achieve efficient and uniform mixing, especially when processing powders with high moisture content or those prone to caking. This can easily lead to uneven mixing and clumping, resulting in a lot of residue adhering to the mixing blades during the mixing process, thus reducing the working efficiency and service life of the mixing blades. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a mixing barrel for hot drying of mixed powders, including a mixing barrel with an inner shell and an outer shell. The mixing barrel has a feed inlet and an air outlet at the top and a discharge outlet at the bottom. A drive motor and a drive fan are located at the center of the top. The drive motor is connected to a rotating shaft, and an air duct is installed inside the rotating shaft. Stirring blades and air nozzles are staggered on the left and right sides of the rotating shaft. The air nozzles are located above the stirring blades and are obliquely downward. The number of air nozzles corresponds to the number of stirring blades. Scrapers are provided at the upper and lower ends of the rotating shaft, and the scrapers abut against the inner wall of the inner shell.

[0004] An insulation layer is formed between the inner shell and the outer shell. A heating pipe is installed inside the insulation layer. The heating pipe is a spiral pipe and is connected to the heating oil tank.

[0005] The outer shell has a support foot at the bottom of its outer wall, and a support base at the lower end of the support foot.

[0006] The stirring blades are curved and are set at an angle to the rotation axis.

[0007] The scraper is equipped with scraping teeth.

[0008] Compared with the prior art, this utility model integrates a hot drying function with a high-efficiency mixing mechanism to achieve uniform mixing and rapid drying of powder, thereby improving production efficiency and product quality. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] like Figures 1 to 2 A mixing drum for hot drying of mixed powders includes a mixing drum with an inner shell 1 and an outer shell 2. The top of the mixing drum has a feed inlet 12 and an air outlet 3, which are connected to a flue gas filter. The bottom has a discharge outlet. The top center has a drive motor 4 and a drive fan 5. The drive motor 4 is connected to a rotating shaft 6. The rotating shaft 6 has an air duct. The left and right sides of the rotating shaft 6 are staggered with stirring blades 7 and air nozzles 8. The air nozzles 8 are located above the stirring blades 7 and are angled downwards. The number of air nozzles 8 corresponds to the number of stirring blades 7. The upper and lower ends of the rotating shaft are respectively provided with scrapers 9, which abut against the inner wall of the inner shell.

[0014] An insulation layer is formed between the inner shell 1 and the outer shell 2. A heating pipe 10 is installed inside the insulation layer. The heating pipe 10 is a spiral pipe and is connected to the heating oil tank to dry the mineral powder and reduce its moisture content.

[0015] The bottom of the outer wall of the outer shell 2 is provided with a support foot 11, and the lower end of the support foot 11 is provided with a support base to improve the stability of the mixing tank.

[0016] The stirring blades 7 are curved and set at an angle to the rotating shaft 6 to improve the mixing efficiency and reduce the adhesion of mineral powder to the blades.

[0017] The scraper 9 is equipped with scraping teeth to improve the efficiency of scraping off the mineral material adhering to the inner wall.

[0018] During use, the mineral powder enters the mixing tank through the top feed port 12. The drive motor 4 is started, which drives the rotating shaft 6 to rotate, thereby stirring the mixing blades 7 and scraping off the adhering substances on the inner wall with the scraper 9. The heating oil tank and drive fan 5 are started to heat the heating tube to dry the mineral powder. The air outlet nozzle 8 blows off the adhering substances on the mixing blades 7 and helps to distribute the heat evenly in the mixing tank, thus accelerating the drying rate. After the stirring and drying are completed, the mixture is output from the discharge port.
