The utility model relates to laser cladding processing technical field, concretely is a kind of laser cladding metal additive manufacturing equipment, including the connecting assembly for being connected in the wall of extension long tube spray head, multiple rollers are equipped in the circumferential direction on connecting assembly, the fan blade of coaxial setting is respectively fixedly installed on each roller, and the outer periphery of multiple rollers is used to contact the inner wall of workpiece simultaneously, and with the rotation of workpiece homodirectional rotation, to realize that fan blade rotates under the driving of roller and generates airflow.The utility model can inhibit the elastic deformation of the extension long tube spray head far end by the rotation of roller set, ensure light path transmission and spot size stability, improve cladding layer precision, quality and efficiency.Meanwhile, fan blade rotation can efficiently discharge cladding heat, slow down component aging, prolong service life, protect high-quality cladding layer formation;And fan blade rotation can also discharge excess powder and smoke, improve processing visibility and efficiency, reduce cladding layer surface roughness, improve surface quality.

This invention relates to the field of compound fertilizer production technology and provides a high-tower granulation device for compound fertilizer production. The device includes a first high-tower body, and a second high-tower body slidably disposed above the inner cavity of the first high-tower body. Lifting components are provided on the surfaces of both the first and second high-tower bodies. The lifting components include a first annular fixing plate and a second annular fixing plate. The first annular fixing plate is fixedly disposed on the outer surface of the first high-tower body, and the second annular fixing plate is fixedly disposed on the outer surface of the second high-tower body. By using the lifting components, a hydraulic push rod drives the second annular fixing plate to rise and fall. The second annular fixing plate, in turn, drives the second high-tower body to slide and rise and fall along the inner wall of the first high-tower body, thereby adjusting the material drop height. By adjusting the drop height, the impact speed of the granules is controlled, preventing granule breakage or unevenness, ensuring that the material is formed under optimal conditions, and improving the practicality and granulation uniformity of the device.
