Abstract
The utility model discloses a waste copper regeneration vertical open-hearth furnace which is composed of a shaft furnace and two open-hearth furnaces. The smelting unit consumption can be reduced through the shaft furnace. By the two open-hearth furnaces, the continuous operation problem of smelting of the shaft furnace is solved, heating waste caused by stopping working of the shaft furnace is avoided, and gas consumption is saved. Nozzles are utilized to heat, so that flame rigidity is improved, metal is smelted in accelerating mode, time that the metal is exposed in strong heat is shortened, refining effect of the open-hearth furnaces is good, and the method obviously plays a role of saving energy and emission reduction.
Description
Technical field
The utility model relates to the perpendicular open hearth of a kind of copper scrap regeneration.
Background technology
Reclaim the used smelting furnace type of Metal Melting technique and roughly be divided into three phases:
What first stage used is open hearth.Extensively used because it is simple to operate, production efficiency is high, production capacity is large.But periodical operation causes the thermal efficiency low and seriously polluted, does not meet the industrial development direction of current low-carbon environment-friendly, therefore will move towards superseded.
What second stage used is shaft furnace.Tall and big body of heater makes material and flue gas that more fully heat transfer be arranged, and makes the thermal efficiency of melting that obvious lifting arranged.But its operation is difficulty relatively, and is difficult to control oxygen content in the copper fusion process, causes unstable product quality.
What three phases used is perpendicular open hearth.This type of furnace has been brought into play open hearth and shaft furnace some advantages separately, economizes than open hearth heat dissipation, be easy to control oxygen content than shaft furnace, and floor space is little.But use single cascaded structure to wait for that this process still can be brought the limited of thermal waste and output because the intermittently operated of open hearth makes shaft furnace also have to stop work.
In order to take into account economic benefit and ambient influnence, need to advance to improve the type of furnace, make operation continuously, further improve heat utilization efficiency.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of copper scrap regeneration perpendicular open hearth, can Effective Raise continuous production, and be beneficial to energy-saving and emission-reduction.
For achieving the above object, the technical solution of the utility model is as follows:
The perpendicular open hearth of a kind of copper scrap regeneration is characterized in that described perpendicular open hearth is comprised of a shaft furnace and two open hearths.
Preferably, described shaft furnace bottom is ramped shaped, and gradient is 13-15 °.
Preferably, top, described shaft furnace slope is provided with burner.
Preferably, described shaft furnace slope end is provided with the conversion mouth, automatically controls shaft furnace periodically in turn to two open hearth dischargings.
Preferably, the model of described two open hearths is identical.
Preferably, the material flow of described shaft furnace is the twice of each open hearth material flow.
The perpendicular open hearth of a kind of copper scrap regeneration that the utility model provides has three large advantages:
The one, the effect of saving the energy is arranged.Because the high-temperature flue gas that produces in the perpendicular open hearth all must partly discharge by shaft furnace, so the copper-containing raw material in energy and the body of heater carries out sufficient heat exchange, make copper-containing raw material before fusing, also be subject to preheating, also just reduced the melting heat dissipation.
The 2nd, the effect that reduces discharging is arranged.Owing to reduced the melting heat dissipation, used gas quantity also reduces, and has reduced direct fuel waste gas.And burning residual air and flue gas all discharge by shaft furnace and have reclaimed heat, so temperature of exhaust gas is lower, if use the cooling of air cooling method can reduce the amount of mixing air, have indirectly reduced again post processing waste gas.
The 3rd, improved the quality of product.The burner flame rigidity is large, and metal molten is fast, has shortened the time of staying of copper in high temperature.Since airtight in the middle of the perpendicular open hearth integrative-structure, therefore can not contact extraneous oxygen, and oxygen content is effectively controlled, so product quality is guaranteed.

The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
According to Fig. 1, the perpendicular open hearth of copper scrap regeneration is comprised of the open hearth (open hearth 112 and open hearth II13) of a shaft furnace 11 and two same models.The bottom of shaft furnace 11 is ramped shaped, and top, slope is provided with burner 14,, the slope end is provided with conversion 15, and control wheel flows to open hearth I and open hearth II discharging.
Operation principle of the present utility model is:
Copper-containing raw material is carried out filler in shaft furnace 11, conversion mouthful 15 furnishings are to open hearth I 12 chargings, burner 14 heating make the copper-containing raw material melting of shaft furnace 11 bottoms, and along the slope by conversion mouthfuls 15 to open hearth I 12 dischargings, add continuously copper-containing raw material from shaft furnace 11 tops in the constantly reduction process of shaft furnace 11 packing layers.After open hearth I12 fills it up with, close between conversion mouthful 15 automatic control shaft furnaces 11 and the open hearth I12, open between shaft furnace 11 and the open hearth II13, molten copper changed course open hearth II13 charging.Shaft furnace 11 keeps laser heating, and the copper liquid that while open hearth I12 finishes refining carries out discharging.Open hearth I12 discharging is complete, and after open hearth II13 filled it up with, conversion mouth 15 was adjusted back original state.Repeat aforesaid operations and can realize serialization production.When the melting flow velocity of shaft furnace 11 during just in time for the twice of each open hearth speed of production reach maximum.Whole process shaft furnace can continuous operation, and operating temperature is basicly stable, and heat utilization rate can be up to 60%, and control has obvious effect to energy-saving and emission-reduction easily.Copper open-assembly time in heat-flash is short, has prevented over oxidation, and the copper after melting can pull into the copper bar for 8 millimeters of the diameters of cable.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
