It is set in a vertical state, and then the negative pressure pipe 1 is used to connect with the external negative pressure equipment, so that the top cover 2 and the enclosure 3 are in a negative pressure state, and then the crushed lithium manganate powder is injected into the oil feed port 5 into the feeding trolley 4. During the process of using the feeding trolley 4 to receive the lithium manganate powder, the top cover 2 and the enclosure 3 are always in a negative pressure state, preventing the dust generated during the receiving process from escaping to the outside through the gap between the top cover 2 and the enclosure 3, preventing environmental pollution and avoiding harm to the health of workers.
