Abstract

An energy-saving environmental-friendly cupola furnace comprises a furnace body, a metal liquid outlet, a slag outlet, a waste gas exhaust port, a waste gas treatment device and an energy recovery device. At least two material bells which are connected in series are arranged above a feeding port of the furnace body in a connected mode in sequence, wherein each material bell comprises a hopper, a bell vale and a bell valve rod of the bell valve. Each bell valve is in a column-shaped structure, wherein the diameter of the upper end of the structure is smaller than that of the lower end of the structure. The side face of each bell valve is a valve surface. Each bell valve rod is fixedly connected with the upper portion of each bell valve. Under the working condition of blanking of each material bell, each bell valve rod is driven by a driving mechanism to jack each bell valve away from a discharge port of each hopper. Under the working condition of feeding of each material bell, each bell valve rod is driven by the driving mechanism to draw each bell valve away downwards to the discharge port of each hopper. When the energy-saving environmental-friendly cupola furnace is in working, the material bells are closed at first, raw materials are added to the hoppers sequentially, the material bells are opened for feeding in sequence through the driving mechanism from the top to the bottom, and a previous material bell is closed when a next material bell is opened. Operation is simple. After flowing through the waste gas exhaust port and a pipeline of the waste gas exhaust port, entering the waste gas treatment device and being dedusted, waste gas can be only used as a hot source and fuel to preheat inlet air. The energy-saving environmental-friendly cupola furnace has the advantages of being simpler in structure, lower in cost, easy to machine and operate and safe and reliable in usage.

Description

A kind of furnace cupola of energy-conserving and environment-protective
Technical field
The utility model relates to the metallurgical casting equipment technical field of smelting metal, particularly relates to a kind of furnace cupola of energy-conserving and environment-protective.
Background technology
Casting is one of important foundation industry of machine building industry, occupies considerable status in the national economic development.Having more than 28000 foundry enterprise in China's casting industry, is the first big country of world production cast article.And the most of foundry enterprise of China is all to use traditional cold blast cupola to carry out melting.
In prior art, furnace cupola is one of visual plant of deposite metal in the metallurgical casting production technology, after by furnace cupola, metal derby or ingot being fused into molten metal, in order to the casting metal foundry goods.Furnace cupola is a kind of smelting furnace of vertical cylinder-like structure, includes body of heater, molten metal outlet, slag notch, exhaust vent etc.Furnace cupola is main multiplex in the production of the metal castings such as cast iron, also can be in order to coordinate pneumatic steelmaking.Furnace cupola claims furnace cupola because of its furnace roof opening upwards.
Since 20th century, the structure of furnace cupola and smelting technology thereof have had very great development, mainly contain: 1. many exhaust outlets blast cupola furnace, this is the little Cupola of the two or more rows that occurs for the burning of strengthening the lean coke that ash content is high, lumpiness is little, intensity is low, the air port gross area only accounts for 5% left and right of sectional area in stove, tuyere area stove footpath dwindles, and enlarges gradually to fusion zone.2. two outlet opening wide pitch blast cupola furnace, its tuyere pitch are than normal large 2~3 times, and between 500~900 millimeters, every row's air intake can be supplied with by independent bellows, also can be provided by total bellows.3. Duplex melting of cupola and induction furnace melting can be given full play to melting capacity and the good overheated ability of electric furnace of furnace cupola excellence.4. improve wind pushing temperature, or increase the oxygen content in air-supply.
Yet, the equal ubiquity of this class furnace cupola of the prior art following problem: the high-temp waste gas of fusion process makes progress outside the furnace roof opening flows out body of heater along the inner chamber of body of heater, wherein some is that directly discharging passes into atmosphere, and some is that requirement according to environmental protection is disposed to atmosphere again after the dust pelletizing system dedusting.Thereby make casting place surrounding enviroment be in the misty state of ash throughout the year.And its coke ratio is high, it is large to pollute, and is the rich and influential family of power consumption and blowdown, this environmental requirement more and more high now, seriously restricted development and the growth of foundry industry.And high-temp waste gas also contains CO except not processing fully clean dust 2, SO 2, N 2, and the pernicious gases such as a large amount of CO that produce because of the coke incomplete combustion, this is not only to environment, and cause CO poisoning and damage healthy to the operating personnel in casting place, even therefore death occur, and this has become the hard nut to crack that casting industry needs to be resolved hurrily for a long time.Simultaneously, the discharging of high-temp waste gas has also caused the loss of a large amount of heat energy, and combustible a large amount of CO, a small amount of H 2And CH 4Energy loss Deng combustible.
(number of patent application is: 201110359709.7) disclose a kind of " charging system of furnace cupola ", the charging system of the furnace cupola of this patent application comprises feeding device and material guide device to Chinese invention patent application.Material guide device has two, is separately positioned on the front side of corresponding furnace cupola, and two material guide devices are divided into Guide materials device and right side material guide device by the difference of its position, residing left and right.Two material guide devices include support machine member and material guide structure spare, and two material guide devices are with respect to one between them sagittal vertical guide almost symmetry.Above-mentioned material guide structure spare comprises deflector chute, and the opening of deflector chute is towards upper rear, and the front end position of deflector chute is fixedly connected on support, and after making deflector chute integral body according to front height, low inclination mode arranges.The guide rail of feeding device is the top to the front and back that are horizontally set on two material guide devices to the middle part along the left and right, thus make that hopper can be in two material guide devices any one above carry out blanking, can satisfy two furnace cupolas and use.By its material guide device, outside material being imported to reach in furnace cupola thus avoids high-temp waste gas to make progress outside the furnace roof opening flows out body of heater along the inner chamber of body of heater.
But the charging system structure of this furnace cupola is more complicated, and its control and operation are also more complicated, and the loss of still failing to solve a large amount of heat energy, and combustible a large amount of CO, a small amount of H 2And CH 4Energy loss problem Deng combustible.
