[0031] The working principle and use process of this utility model:

[0032] When in use, first place the weighing basket 2 on the electronic scale 3, then inject aluminum hydroxide into the weighing basket 2, use the electronic scale 3 to weigh the injected aluminum hydroxide, until the weight of the aluminum hydroxide reaches a predetermined value, stop the continued injection of aluminum hydroxide, control the two first hydraulic cylinders 5 to extend, so that the two first hydraulic cylinders 5 push the electromagnet 9 to fit with the weighing basket 2, and the electromagnet 9 attracts the weighing basket 2 with the help of magnetic force after being energized, control the second motor 20 to drive the screw rod 18 to rotate forward, so that the screw rod 18 drives the weighing basket 2 to move upward in the form of a screw rod transmission, and when the weighing basket 2 leaves the electronic scale 3, control the two first hydraulic cylinders 5 to shrink to the starting length, and when the height of the weighing basket 2 exceeds the hopper 22, stop the operation of the second motor 20, control the first motor 15 to drive the support 16 to pull the weighing basket 2 to rotate forward 180°, so that the weighing basket 2 moves to above the hopper 22;
