Cyclic type mechanical conveying device for steel balls

Abstract

The invention relates to a cyclic type mechanical conveying device for steel balls. The cyclic type mechanical conveying device comprises a supporting frame, a steel ball conveying hopper, a driving wheel, a driven wheel, two rows of chains, a fine adjustment correcting plate, a rough adjustment correcting rod and a mechanical discharge blocking wheel, wherein the driving wheel, the driven wheel, the two rows of chains, the fine adjustment correcting plate, the rough adjustment correcting rod and the mechanical discharge blocking wheel are fixed to the supporting frame. The fine adjustment correcting plate, the coarse adjustment correcting rod and the mechanical discharge blocking wheel are fixed to an upper transverse bearing frame. The fine adjustment correcting plate and the coarse adjustment correcting rod are arranged in parallel. The fine adjustment correcting plate is located below the coarse adjustment correcting rod. The distance between the fine adjustment correcting plate and the coarse adjustment correcting rod corresponds to the overall height of the steel ball conveying hopper. The steel ball conveying hopper containing steel balls makes contact with the fine adjustment correcting plate and the coarse adjustment correcting rod at first for horizontal correction and then makes contact with the mechanical discharge blocking wheel so as to provide overturning driving force through the mechanical discharge blocking wheel.

Description

technical field [0001] The invention relates to the technical field of waste heat boilers, in particular to a circulating steel ball mechanical transport device suitable for use in steel ball dust removal type submerged arc furnace waste heat boilers. Background technique [0002] Submerged arc furnaces are generally divided into three types of furnaces, the first is a fully enclosed type, the second is a semi-closed type with a low fume hood, and the third is an open type with a high fume hood. Because the semi-closed furnace contains very little combustible gas, the temperature is as high as 400 ° C, and more air is mixed in from the furnace door, and the amount of smoke is relatively large. It is suitable to use waste heat boilers for heat exchange and power generation, and the thermal efficiency can reach about 26% and 28%, but the difficulty is that most of the dust in the flue gas has a diameter of 0.1-0. Containing nano-sized particles, these particles show different...

It is suitable to use waste heat boilers for heat exchange and power generation, and the thermal efficiency can reach about 26% and 28%, but the difficulty is that most of the dust in the flue gas has a diameter of 0.1-0. Contains nano-sized particles, these particles show different cohesive properties under different temperature zones and humidity, and are very easy to adhere to the surface of chimneys, flues, and metal pipes, resulting in a sharp decrease in the heat transfer efficiency of the heat transfer surface

[0003] At present, there is a cleaning solution to solve the above technical problems in the prior art. However, due to the steel ball jumping between the heating surfaces from top to bottom, the steel ball separation and collection device output steel balls in an uncertain amount, and the steel balls fall into the steel ball transport bucket. Finally, the shape of the accumulation of steel balls stained with furnace ash deviates, resulting in the steel ball transport bucket cannot maintain a horizontal state, and the steel ball transport bucket with a certain inclination angle cannot pour all the steel balls into the steel ball spreading device when it passes through the mechanical discharge retaining wheel , reducing the amount of steel balls entering the boiler, thereby reducing the cleaning effect and wasting electric energy
