Abstract

The invention relates to a winnowing device capable of reducing mud content of foundry sand. The winnowing device includes a discharging device, a winnowing mainframe, a dust collector fan and a bag dust collector. The discharging device includes a discharging hopper and a conveying device. The sand material output end of the conveying device is placed on the upper portion of a feeding port of thewinnowing mainframe. A material-flinging disc and a baffle plate are arranged in the winnowing mainframe. The lower end of the winnowing mainframe is provided with a sand material output port. Meanwhile, one side of the winnowing mainframe is communicated with an air outlet of the dust collector fan, and sand dust in the winnowing mainframe is conveyed into the bag dust collector through a dedusting pipe. According to the winnowing device, quantitative discharging can be achieved, sand is flung into the winnowing mainframe through a centrifugal effect of the material-flinging disc, and the sand descending speed is reduced through the blockage by the baffle plate. Meanwhile, through the action of the dust collector fan, the sand is dedusted, and particles smaller than the standard range are collected into the bag dust collector, to achieve the goal of reducing the mud content.

Description

technical field [0001] The invention relates to the field of fan devices, in particular to a winnowing device for reducing the mud content of foundry sand. Background technique [0002] GBT9442-2010 "Silica Sand for Foundry" is the national standard for the detection and use of foundry sand in my country's foundry industry, which stipulates that the percentage of the mass of particles with a particle size of less than 0.020mm in the silica sand for foundry to the total mass of the sand sample is called the mud content. However, in the production process of foundry sand, due to the problem of screening efficiency, the mud content has been high, resulting in the use of too much binder in the precision resin casting process, causing casting defects and reducing the yield. Simultaneously, also increased the polluted environment. Contents of the invention [0003] In view of this, the object of the present invention is to provide a winnowing device for reducing the mud content...
