Steel ball dedusting-type submerged arc furnace waste heat boiler capable of preventing steel ball from losing

Abstract

A steel ball dedusting-type submerged arc furnace waste heat boiler capable of preventing a steel ball from losing comprises a circulating-type steel ball mechanical dedusting device. A discharging port of a conical funnel of a steel ball air locking and feeding device of the circulating-type steel ball mechanical dedusting device is connected with a lead passage, an angle A from the conical funnel to the lead passage ranges from 90 degrees to 120 degrees, a rocker arm is fixed oppositely to the conical funnel through a pin shaft, one end, at which a rotating wheel is arranged, of a steel ball discharge triggering member is close to the lead passage, one end of a dust-flying-proof flexible sleeve is connected at a free end of the lead passage in a sleeved manner, and an opening is formed in the other end of the dust-flying-proof flexible sleeve to convey the steel ball to a steel ball transporting bucket. Moving speed of the steel ball is reduced through the lead passage and the dust-flying-proof flexible sleeve, so that the steel ball is ensured not to be bounced out after falling into the steel ball conveying bucket.

Description

technical field [0001] The invention relates to the technical field of waste heat boilers, in particular to a steel ball dust removal type submerged arc furnace waste heat boiler which prevents steel balls from being lost. Background technique [0002] The utilization of waste heat in the boiler industry is an important topic in energy conservation at present, and it has high economic and social benefits. For example, the waste heat utilization of smelting furnaces in the boiler industry converts the waste heat discharged from the smelting furnaces into other energy sources, such as electric energy, steam energy, or as power to directly drive other mechanical equipment and heat supply. [0003] Submerged arc furnaces are generally divided into three types of furnaces. The first type is fully enclosed type, the second type is semi-closed type with low fume hood, and the third type is open type with high fume hood. Because the semi-closed furnace contains very little combusti...

Problems solved by technology

However, this invention has the following disadvantages: since the steel balls jump between the heating surfaces from top to bottom, under the action of the gravity of the steel balls themselves, the steel balls output by the steel ball lock wind charging device move at a relatively high speed, causing the steel balls to flow from the steel ball transport bucket. Popping out, scattered on the ground and lost, causing maintenance personnel to buy new steel balls to supplement the amount of steel balls, increasing costs and wasting materials
