Abstract
A corundum arc furnace closed dust removal system comprises a motor lifting system and an electric furnace, a chimney is communicated with a dust removal device through a fan, and the dust removal device is communicated with a dust removal mouth on an electric furnace jacket through a pipeline. Air can be directly pumped from the interior of the furnace, the amount of smoke is small, needed dust removal equipment is small, and costs of investment and daily operation are relatively low. The corundum arc furnace closed dust removal system can effectively collect a large amount of dust generated in a production cycle, greatly improves environment conditions of an electric furnace operating platform and an electric furnace production workshop; dust removal effects are stable, average dust removal efficiency reaches above 95%, and the amount of smoke discharge is within the national standard control scope; and the corundum arc furnace closed dust removal system receives good economic benefits.
Description
Technical field
The utility model belongs to the equipment in the refractory material production process, relates in particular to the closed dust pelletizing system of founding diamond spar series refractory material productive power arc stove.
Background technology
Along with the continuous lifting of domestic castable refractory enterprise equipment, electric arc furnaces has progressively been realized comprehensive production domesticization.For various reasons, dust pelletizing system smoke evacuation dust removing effects as the electric arc furnaces vitals is not good, cause in the fusion process a large amount of electric furnace dusts to fill the air to be diffused into around the inside and outside and plant area in workshop, so not only cause environmental pollution, and caused scattering and disappearing of large content of starting materials.The dust pelletizing system that present domestic founding corundum refractory manufacturer generally adopts is furnace roof umbrella hood dust collecting system, as shown in Figure 1, and 1, chimney, 2, blower fan, 3, deduster, 4, pipeline, 5, electric furnace, 6, the motor upgrade-system, 7, the umbrella shape dust collection.This dust excluding hood is higher apart from electric furnace dirt source, and the umbrella hood structure of umbrella shape dust collection is larger, and dust removing effects is subjected to cross-flowly to affect greatlyr, and enterprise practical result of use reflection does not obtain good dust removing effects.In a sense, the key of electric stove dust success be that dedusting method selects appropriately whether.
The utility model content
Technical problem to be solved in the utility model is the shortcoming that overcomes traditional umbellate form dust pelletizing system dust removing effects effect deficiency, for castable refractory manufacturing enterprise provides a kind of novel closed dust pelletizing system.
In order to solve the problems of the technologies described above by the following technical solutions: the closed dust pelletizing system of a kind of corundum arc furnace, comprise motor jacking system and electric furnace, chimney is communicated with deduster by blower fan, and deduster is communicated with by the dedusting mouth that pipeline and electric furnace put.
Described dedusting mouth is on the boiler clothing between electric furnace molten bath and the upper strata bell.
Described pipeline external is provided with water cooling plant.
Described deduster is JY41-32C type pulse type filter drum dust collector.
The utility model is directly bled in stove, and exhaust gas volumn is little, and required cleaner is minimum, and investment and daily running expense are also lower.The a large amount of dust that produce in production cycle effectively can be collected, greatly improved the environmental condition of furnace operation platform and electric furnace workshop; Dust removing effects is stable, and average dust removal efficiency reaches more than 95%, and smoke discharge amount is up to state standards within the control range; And won good economic benefit.
Description of drawings
Fig. 1 is background technology accompanying drawing of the present utility model.
Fig. 2 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 2, the closed dust pelletizing system of a kind of corundum arc furnace, comprise motor jacking system 6 and electric furnace 5, chimney 1 is communicated with JY41-32C type pulse type filter drum dust collector 3 by blower fan 2, deduster 3 is communicated with by the dedusting mouth that the middle boiler clothing position between pipeline 4 and electric furnace molten bath and the upper strata bell arranges, and pipeline 4 outsides are provided with water cooling plant.
The dedusting mouth reaches the purpose of dedusting by the pipeline communication blower fan.That the raw material of founding diamond spar series refractory material is the powdery siccative but use procedure pays particular attention to, when the exhausting amount was large, particularly in reinforced melting stage, a large amount of lightweight materials were pumped, can cause like this dust pelletizing system to stop up easily, having changed simultaneously the raw material proportioning affects product quality.Therefore, the methods of operating that adopt little exhausting amount and reinforced process blowing-out machine in actual motion more.
Through the produced on-site experiment statistics, electric furnace recyclable dust 220kg every day, it is aluminium oxide and volatile carbon that chemical analysis reality reclaims the powder main component, advances simple process and can melt down recycling.My company has 5 corundum arc furnaces, and nearly 400 tons of year recyclable dust can save material and drop into 1,000,000 yuan, for company has won good economic benefit.
