Environment-friendly used casting sand dry recovery and treatment equipment

Abstract

The invention discloses environment-friendly used casting sand dry recovery and treatment equipment. The environment-friendly used casting sand dry recovery and treatment equipment comprises a bucket elevator, a used sand conveying and crushing device, a vibrating screen, a rotary sand rolling device and a dust collection device. The used sand conveying and crushing device, the vibrating screen and the rotary sand rolling device are mounted and fixed from top to bottom in sequence. The dust collection device communicates with the used sand conveying and crushing device, the vibrating screen and the rotary sand rolling device through dust collection pipelines correspondingly. The rotary sand rolling device comprises a sand cylinder, a sand rolling wheel, a sand turning shovel and a rotating motor II. The front end of a rotary shaft of the rotary motor II is provided with a horizontal connecting rod. The two ends of the horizontal connecting rod are provided with the sand rolling wheel and the sand turning shovel correspondingly. The environment-friendly used casting sand dry recovery and treatment equipment can effectively improve the recovery quality and efficiency of used sand by crushing, screening, turning and grinding used casting sand, and is high in continuous production capacity and capable of conducting dust collection in each step and guaranteeing reduction of environmental pollution.

Description

technical field

[0001] The invention relates to a recycling equipment for used foundry sand, in particular to an environment-friendly dry method recycling and processing device for used foundry sand. Background technique

[0002] A large amount of waste foundry sand will be produced in the casting production process. Manual screening and recycling is not only inefficient, but also cannot be fully recycled. The recycling quality and efficiency can be effectively improved through machinery, but the traditional mechanical dry method of recycling foundry sand The equipment structure of sand is relatively complicated, and the recovery effect is poor. Not only the energy consumption is high, but also the recovery efficiency is relatively low, and continuous production cannot be carried out, or the energy consumption is high, which increases the recovery cost of used sand and also produces Larger dust, thus causing serious pollution to the environment.
