AI Technical Summary

Technical Problem

Existing dust collection devices are ineffective at collecting dust containing oil and gas molecules, leading to inconvenience in removal, increased manual cleaning burden, and high costs.

Method used

A vertical waste ash hopper is connected to a regenerable dust collector, a shot blasting dust collector, and a sand removal dust collector. Dust collection bags are built into the casting dust collector and the hot-fired dust collector. Combined with a pneumatic conveying tank and waste ash humidification and stirring, a closed loop is formed to treat dust containing oil and gas molecules.

Benefits of technology

It achieves effective collection of oil, gas and dust, reduces the stickiness of mixed particles, facilitates cleaning of dust collector bags, reduces the burden of manual cleaning, and lowers costs.

Abstract

This utility model relates to a recycling system for foundry waste dust, comprising a regeneration dust collector, a shot blasting dust collector, a sand removal dust collector, or multiple dust collectors, which respectively connect to a vertical waste ash hopper via a first fan, a second fan, a third fan, or multiple fans. The vertical waste ash hopper then discharges the waste ash through a humidified and stirred process. The vertical waste ash hopper is further connected to a casting dust collector and a hot work room dust collector via fans, each with a first and a second dust collector bag. The casting dust collector and the hot work room dust collector then connect to the vertical waste ash hopper via a pneumatic conveying tank, and finally discharge the waste ash through a humidified and stirred process. The first and second soot blowing trolleys are designed to facilitate the rapid separation of floating matter such as oil, gas, and dust. Larger particles naturally fall into the first or second dust collector bag, while the mixed smaller particles, oil, gas, and dust return to the vertical waste ash hopper via the pneumatic conveying tank, and are finally discharged through a humidified and stirred process.
