Description

Powder material static eliminating equipment for vibrating screen Technical Field The utility model relates to the technical field of sieving, in particular to powder material static eliminating equipment for a vibrating screen. Background The vibrating screen works on the principle that materials are separated by vibrating force. The method comprises the following steps of placing materials to be screened into a feed inlet of a vibrating screen, driving a vibrator to vibrate through a motor, and enabling the screen to start vibrating. The material receives the effect of vibration force on the screen cloth, and the material of different granularities can fall into different delivery outlet and reach the effect of screening material. The conventional vibrating screen has the following problems in sieving operation: 1. The vibration friction of the material on the screen can generate static electricity, so that the material powder generates discharge phenomenon after carrying the static electricity, and even the dust in the air can be ignited to generate flash explosion phenomenon, thereby influencing the production safety. 2. The vibration of the material on the screen mesh can generate static electricity, so that the material powder is accumulated after being charged with the static electricity, and small powder is accumulated into larger particles to block the screen mesh, so that the screening efficiency is reduced, and the screening efficiency is affected. 3. The vibration of the material on the screen can generate static electricity, so that the material powder is accumulated after being charged with the static electricity, and small powder is accumulated into larger particles to block the screen, thereby influencing the material yield of the material with a certain size. Therefore, the vibrating screen of the static eliminator is added, static generated when materials are rubbed during vibration can be reduced, the production safety is improved, the screening efficiency and the material yield of the materials are improved, and the novel powder static eliminator for the vibrating screen is provided to solve the problems.
