Bag-type dust collector for secondary lead process

By driving the support rings at both ends of the dust collector bag to move synchronously through the dust shaking mechanism, the problem of the cleaning force being difficult to be evenly transmitted to the middle and lower parts is solved, achieving efficient dust cleaning effect and stable filtration performance, and extending the service life of the filter bag.

AI Technical Summary

Technical Problem

The existing dust collectors used in lead recycling processes have dust removal mechanisms that only drive the entire dust collector bag up and down through a single top drive point. This makes it difficult to evenly distribute the dust removal force to the middle and lower areas, resulting in dust accumulation in the middle and lower parts of the dust collector bag and a decrease in filtration efficiency.

Method used

The dust-shaking mechanism synchronously drives the upper and lower support rings at both ends of the dust collector bag to reciprocate in opposite directions. Combined with the reliable meshing transmission between the toothed plate and the tooth groove and the rapid return mechanism provided by the reset spring, a powerful shaking wave is formed to ensure that the dust-cleaning force is evenly transmitted to the entire length of the filter bag.

Benefits of technology

It effectively shakes off highly adhesive fine lead dust, improving cleaning efficiency and thoroughness, enhancing the cleaning effect in the middle and lower parts, extending the service life of the dust collector bags, maintaining stable filtration efficiency, and reducing system operating resistance.

Abstract

The invention relates to the technical field of bag-type dust collectors, and discloses a bag-type dust collector for a lead regeneration process, which comprises a dust collection bag, an upper support ring, a lower support ring, a collection hopper and an ash shaking mechanism, the upper supporting ring and the lower supporting ring are fixedly arranged at the two ends of the dust collecting bag respectively; the upper supporting ring is fixedly communicated with a flexible connecting port, and the lower supporting ring is fixedly communicated with the collecting hopper; and the dust shaking mechanism is arranged at the side part of the dust removal cloth bag. According to the bag-type dust collector for the lead regeneration process, the dust shaking mechanism synchronously drives the upper supporting ring and the lower supporting ring at the two ends of the dust collecting bag to do opposite and back-to-back reciprocating motion, so that dust cleaning force can be uniformly transmitted to the whole length of the filter bag, and particularly, the dust cleaning effect of the middle lower part is improved; and the technical problems of non-uniform ash removal force transmission and easy hardening of the middle lower part of the filter bag caused by traditional single top driving are thoroughly solved.
