Shakeout machine facilitating recycling treatment of old sand and scrap iron and shakeout

Abstract

The invention discloses a shakeout machine facilitating recycling treatment of old sand and scrap iron and shakeout. The shakeout machine comprises crushing devices and a screening device, wherein thecrushing devices comprise first rotary motors and crushing rollers arranged at one output ends of the rotary motors. The screening device comprises a screening plate which is formed by two electromagnetic suction plates, baffles are arranged on the two sides of the screening plate, second rotating motors are arranged on the baffles, sand guide rollers are arranged at the output ends of the secondrotary motors, and sand collecting boxes are arranged at the bottom ends of the two electromagnetic suction plates of the screening plate. The device can be used for carrying out crushing treatment on the old sand generated in the shakeout process of casting, so that the falling of the old sand is facilitated, and the old sand is prevented from being pasted on the inner wall of a sand collectinghopper or blocking a sand outlet, and meanwhile, the scrap iron in the old sand can be screened and separated, so that the old sand and the scrap iron can be conveniently recycled and used, and the utilization of casting material resources is optimized.

Description

technical field [0001] The invention relates to a sand shakeout machine, in particular to a sand shakeout machine which is convenient for the recovery and treatment of old sand and iron filings and sand shakeout. Background technique [0002] The shakeout machine is a casting equipment used for the separation of molding sand and castings. Vibration and impact promote the separation of the sand box from the molding sand, the separation of castings and molding sand, and the crushing of sand clusters. When more castings are shaken out, more old sand may cause sand sticking and clogging in the sand collection bucket, and the old sand cannot fall out quickly, and it cannot be completely recovered. The crushing of sand clusters is not very sufficient, there will often be a large accumulation of sand clusters that will block the sand collection bucket, and there will often be more iron filings in the old sand. If the old sand is discarded directly, more iron filings that can be re...

[0002] The shakeout machine is a casting equipment used for the separation of molding sand and castings. Vibration and impact promote the separation of the sand box from the molding sand, the separation of castings and molding sand, and the crushing of sand clusters. When more castings are shaken out, more old sand may cause sand sticking and clogging in the sand collection bucket, and the old sand cannot fall out quickly, and it cannot be completely recovered. The crushing of sand clusters is not very sufficient, there will often be a large accumulation of sand clusters that will block the sand collection bucket, and there will often be more iron filings in the old sand. If the old sand is discarded directly, more iron filings that can be recycled will be wasted, resulting in a waste of foundry resources
