AI Technical Summary

Technical Problem

In the cleaning process of the bag used in the prior art for collecting zinc ash, the dust that has been shaken off is easily attached to the adjacent bags, affecting the cleaning effect, and it is difficult to effectively extend the service life of the bag.

Method used

A zinc ash filter device inside the furnace nose cavity is designed, adopting a retractable bag structure and a mobile partition mechanism. Through the cooperation of the gas chamber and the air blow hole, the bag can be switched between the outer filtration and the inner filtration state, and the bag can be used to The matching of elastic parts and drawstrings enables the bag to be effectively utilized in different positions, increasing the chance of impurities falling, and promoting the cleaning of zinc ash through blowback and compression and extension of elastic parts.

Benefits of technology

It improves the collection efficiency and cleaning effect of zinc ash, extends the service life of the cloth bag, avoids zinc ash adhering to other cloth bags or shells during cleaning, and improves dust removal efficiency.

Abstract

The invention relates to the technical field of dust removal, in particular to a furnace nose cavity interior zinc ash filtering device which comprises a shell, a partition plate and a cloth bag. The partition plate is horizontally arranged in the shell and can move up and down in the shell; a fixing frame is arranged in the cloth bag, is fixed on the partition plate, and is telescopic in the vertical direction; one end of the cloth bag is opened, and the other end of the cloth bag is blocked; a supporting ring is arranged in one end of the cloth bag plug and connected with the fixing frame, and an air blowing hole is formed in the bottom of the supporting ring. The blocked end of the cloth bag is turned inwards and moved upwards from the interior of the cloth bag, the working form of the cloth bag is changed, the utilization rate of the cloth bag is improved, air is blown downwards in the cloth bag in the form changing process of the cloth bag, zinc ash is promoted to fall off, the zinc ash falls off from the interior of the cloth bag after the cloth bag is turned inwards, and the amount of the zinc ash falling into other cloth bags in the cleaning process is reduced. And the zinc ash collection efficiency and the dust removal efficiency of the cloth bag are improved.
