AI Technical Summary

Technical Problem

The existing three-chamber furnace has poor backflow prevention effect when exhausting waste gas during waste aluminum processing, poor waste gas filtration effect, and poor fit between the filter box and the exhaust pipe, resulting in air pollution problems.

Method used

The design incorporates an anti-backflow cylinder and a filter box structure. The anti-backflow cylinder prevents the backflow of exhaust gas through the cooperation of a sealing plate and a spring, while the filter box facilitates filtration through the engagement of clamping blocks and bolts, ensuring smooth discharge and filtration of exhaust gas.

Benefits of technology

It effectively prevents backflow of exhaust gas, improves the filtration effect of exhaust gas, reduces air pollution, and increases the efficiency of waste aluminum recycling and processing.

Abstract

This application provides a three-chamber furnace for waste aluminum recycling, relating to the technical field of waste aluminum recycling equipment. The three-chamber furnace includes a three-chamber furnace body. In this application, an anti-backflow cylinder is installed inside the first exhaust pipe. When waste gas is continuously discharged from the first exhaust pipe, it drives the sealing plate to slide along the inner wall of the slide groove, causing the connecting plug to be discharged from the inner wall of the conveying port. This, in turn, compresses the telescopic rod and the first spring, allowing the waste gas to continuously discharge from the first exhaust pipe. When the waste gas pressure is lower than the external air pressure, the reaction force of the compressed first spring causes the sealing plate to promptly block the conveying port, preventing external gas from flowing back into the three-chamber furnace and affecting the efficiency of the three-chamber furnace in recycling waste aluminum. Simultaneously, when it is necessary to filter and discharge the waste gas, rotating the bolt causes the clamping block to contact the second exhaust pipe. Under the action of the fixing block, the exhaust pipe and the filter box are engaged, facilitating the convenient filtration and conveying of the waste gas.
