Dedusting purifying device for energy-saving environment-friendly melting casting furnace

Abstract

The invention relates to the field of smelting equipment, in particular to a dedusting purifying device for an energy-saving environment-friendly melting casting furnace; the dedusting purifying device comprises a dedusting tank, a purifying tank and a filtering device; the dedusting tank is communicated with the purifying tank through a connection pipeline, the inner upper segment of the dedusting tank is provided with a spiral panel that spirals up along the its axis, the top of the spiral panel is provided with a plurality of support strips that are spiraled up and arranged, the top of the purifying tank is provided with a plurality of nozzles, the filtering device includes primary filter meshes, a secondary filter mesh, and a cleaning mechanism for cleaning the primary and secondary filter meshes, the primary filter meshes are arranged parallelly at intervals right above the secondary filter mesh, the cleaning mechanism includes a first retaining plate in sliding fit with the primary filter meshes, a second retaining plate in sliding fit with the secondary filter mesh, a linkage, and a driving motor, and both the first retaining plate and the second retaining plate are hinged to the linkage. The dedusting purifying device has better effect in purifying waste gas, environmental pollution by waste gas is avoided, and environment protection is achieved.

Description

technical field [0001] The invention relates to the field of smelting equipment, in particular to an energy-saving and environment-friendly dust removal and purification equipment for melting and casting furnaces. Background technique [0002] The traditional cupola directly discharges dust and unburned carbon monoxide into the air, which seriously pollutes the environment. Although there are heating pipes, the temperature rise is limited, the furnace is narrow and cannot be fully burned, the temperature of the furnace is low, and the melting materials are exquisite, so energy consumption Large, high cost, and can only be used as a casting furnace. [0003] Dust removal purifier is a kind of equipment that separates dust and sulfur dioxide from the air flow. It is a relatively common industrial equipment in industrial production such as boilers and polishing. A common dust collector uses a fan to pump out the air inside the dust collector, and a pressure difference is gener...

AI Technical Summary

Problems solved by technology

A common dust collector uses a fan to pump out the air inside the dust collector, and a pressure difference is generated inside and outside the dust collector. It is discharged through the air outlet. However, the above-mentioned dust collectors usually only pass through one filter, so the filter effect is poor, and the effect of deep filter cannot be achieved.
