Foundry waste sand treatment device

Abstract

The embodiment of the invention provides a foundry waste sand treatment device. The foundry waste sand treatment device comprises a cover body, an iron frame is arranged in the cover body, four sliding grooves are fixedly formed in the bottoms of two opposite side faces of the iron frame, a screen is arranged in the iron frame, a transverse beam on the bottom of the screen penetrates the symmetricsliding grooves to be fixedly connected with the cover body, multiple shafts sleeved with casing pipes are arranged on the top of the screen, the casing pipes are provided with multiple swing platesannularly distributed, and the shafts are driven by belt wheels. The foundry waste sand treatment device is simple in structure, the shafts drive the swing plates to rotate left and right, waste sandon the screen can be evenly dispersed, uniform distribution of waste sand on the screen can be ensured, and the sand screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of waste sand treatment, and more specifically, to a casting waste sand treatment equipment. Background technique [0002] At present, the amount of waste sand used in the foundry industry is very large. When using traditional waste sand, sometimes there will be sand sticking and sand inclusions in the castings. When the mold is baked in a kiln and the box is combined, it will produce light and heat radiation and black soot. Flying, causing environmental pollution. The recycling rate of old sand is low, and the annual discharge of foundry waste sand in my country is more than 10 million tons. Due to improper treatment technology, it not only pollutes the environment, but also causes a lot of waste of resources. When the foundry waste sand is recycled and reused, it is necessary to screen and clean the ground sand, and now many of them are manually operated. Or simply mechanically screen out and clean the d...

[0002] At present, the amount of waste sand used in the foundry industry is very large. When using traditional waste sand, sometimes there will be sand sticking and sand inclusions in the castings. When the mold is baked in a kiln and the box is combined, it will produce light and heat radiation and black soot. Flying, causing environmental pollution

The reuse rate of old sand is low, and the annual discharge of foundry waste sand in my country is more than 10 million tons

Due to improper treatment technology, it not only pollutes the environment, but also causes a lot of waste of resources. When the foundry waste sand is recycled and reused, it is necessary to screen and clean the ground sand, and now many of them are manually operated. Or simply mechanically screen out and clean the dust in the waste sand, which is cumbersome and time-consuming, and in the end a lot of resources are wasted, and it still cannot meet the use requirements, so this leads to a lot of foundry waste sand, which is discharged without treatment and pollutes surroundings
