1. A cylindrical ore washer for hydrometallurgical smelting of laterite nickel ore, comprising:
a mounting bracket;
a screening component, wherein the screening component comprises a frame, a cylinder body, a screening cylinder, and a driving component; the cylinder body is rotatably installed on the frame along the axis in a first direction; the screening cylinder is fitted inside the cylinder body and is coaxially arranged with the cylinder body; the screening cylinder has a feed inlet and a discharge outlet at its opposite ends along the first direction, respectively; the screening cylinder is inclined downwards gradually from the feed inlet to the discharge outlet; a cylindrical wall of the screening cylinder is provided with multiple screen holes, the multiple screen holes connect the cylinder body and the screening cylinder; a baffle plate protrudes from an inner sidewall of the screening cylinder; the baffle plate is inclined relative to a radial direction of the screening cylinder, and is located at the discharge outlet, the cylinder body is also equipped with a liquid outlet, the liquid outlet is located at the end of the cylinder body near the discharge outlet; the driving component is installed on the frame and connected to the cylinder body to drive a rotation of the screening cylinder; wherein the frame is movably mounted on the mounting bracket, allowing an inclination angle of the screening cylinder to be adjustable;
a regulator, wherein the regulator is installed on the mounting bracket and connected to the frame; when the frame is moved to a preset position, the regulator fixes the frame in place;
a collection pool, wherein the collection pool is positioned corresponding to the liquid outlet and is used to collect mud and smaller diameter ores discharged from the liquid outlet;
a concentration detection device, wherein the concentration detection device is installed within the collection pool and is used to detect a concentration of the material within the collection pool;
an ore washing component, wherein the ore washing component is installed on the frame and is used to inject high-pressure water into the screening cylinder through the feed inlet to wash the ores; and,
a control device, wherein the control device is electrically connected to the regulator, the ore washing component, and the concentration detection device, allowing the control device to control the operation of the regulator and the ore washing component based on the detected concentration;
wherein the driving component comprises two rotating shafts and a driving motor; the two rotating shafts are located on opposite sides of the cylinder body along a second direction; each rotating shaft is rotatably installed on the frame along the axis in the first direction, and each rotating shaft abuts against an outer side surface of the cylinder body; the driving motor is connected to one of the rotating shafts to drive its rotation, the first direction and the second direction are perpendicular to each other.
