Description

Crucible raw material screening device Technical Field The utility model belongs to the field of raw material screening, and particularly relates to a crucible raw material screening device. Background The Crucible (Crucible) is a vessel for melting and refining a metal liquid and heating and reacting the solid and liquid, and is classified into a porcelain Crucible, an iron Crucible, an alumina Crucible, and the like. The crucible can resist high temperature, and is used for burning and precipitating, melting salts which do not react with the crucible, dehydrating crystal hydrate, and the like. The crucible is made of lime, carbon, other refractory clay and other materials. In order to ensure the production quality of the graphite crucible after film coating, the raw materials of the graphite crucible are required to be screened to prevent impurities from appearing on the surface of the crucible, and a vibrating screen is adopted for sorting in the traditional way, but a large amount of dust is generated during screening in the sorting mode, mainly the phenomenon that the raw materials are lifted when the screened raw materials fall into a screen below due to finer raw materials is caused, and particularly the vibration of a vibration screening machine is severe and the dust is generated in an open mode to be huge. Disclosure of Invention The utility model aims to solve the technical problem of providing a crucible raw material screening device which is simple in structure, convenient and practical, and can enable a screen plate to horizontally move through an eccentric shaking device, so that the raw material can not jump to generate dust during screening, and meanwhile, the raw material can be rapidly spread for screening. The utility model provides a crucible raw materials screening plant, including screening case, power motor, power pivot, power band pulley, play hopper, sieving mechanism and drive belt, screening case top and bottom are provided with feed inlet and discharge gate respectively, power pivot swing joint is in screening case and one end is connected with power motor power pole, power motor installs at screening case top, a plurality of power band pulley is connected in power pivot, a plurality of sieving mechanism installs in the screening case, power band pulley passes through the drive belt and is connected with corresponding sieving mechanism transmission, a plurality of the discharge hopper is connected at screening case lateral wall and with correspond the cooperation of sieving mechanism. Preferably, the screening device comprises a screen positioning ring, an L-shaped material guiding inclined ring, a screen plate, a centralized hopper, an eccentric shaking device and a fixed rod, wherein the screen plate is arranged on the screen positioning ring, one end of the L-shaped material guiding inclined ring is connected to the circumferential surface of the screen positioning ring, a discharging hole is formed in the L-shaped material guiding inclined ring, at least one eccentric shaking device is connected to the inner wall of the screening box through the fixed rod, the upper end and the lower end of the eccentric shaking device are respectively connected with the screen positioning ring and the centralized hopper, a secondary driving belt pulley is connected to the eccentric shaking device, and the secondary driving belt pulley is in driving connection with the power belt pulley through a driving belt. Preferably, the eccentric shaking device comprises a rotating shaft, eccentric bearings and bearings, wherein the rotating shaft is connected to the fixed rod through the bearings, the two ends of the rotating shaft are connected with the eccentric bearings, and the two eccentric bearings are respectively connected with the screen positioning ring and the centralized hopper.
