Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of producing mullite sand, especially to a mullite sand production vibrating screen. BACKGROUND
[0002] Mullite sand is a kind of refractory material with aluminum silicate as the main component, which is made of hard clay with high aluminum and low iron through high-temperature calcination, crushing and screening processes; the main component is aluminum silicate, the higher the aluminum content, the better the quality, and it has the characteristics of low expansion coefficient and high refractoriness.
[0003] In the process of mullite sand production, screening is a relatively important process. The mullite sand after firing needs to be screened several times to separate the mullite sand according to the mesh number. The mullite sand that is not qualified is ground and then screened again. At this time, since the screening machine is open, dust is large during screening, and particles are easy to fly out. Although the vibrating screen for mullite sand production disclosed in the publication No. CN212093134U can effectively prevent dust overflow by increasing the upper cover to make the screening in a relatively sealed state, the unqualified mullite sand is not convenient to discharge and needs to be stopped for centralized treatment. At the same time, the inlet is not sealed, and a small part of dust will still escape from the inlet. At the same time, the vibration motor is directly installed on the screening mesh, and the long-term vibration and the dust-filled working environment will reduce the service life of the vibration motor.
