Abstract
The utility model discloses an intermediate frequency furnace smoke collection device which comprises a smoke collection cover capable of rotating with a furnace body, a rotatable branch smoke pipe and a fixed branch smoke pipe, wherein the smoke collection cover capable of rotating with the furnace body is of a flat cylindrical structure with a big end and a small end; the big end is arranged above the furnace mouth of the intermediate frequency furnace; a charging port of which the diameter is slightly less than that of the furnace mouth of the intermediate frequency furnace is formed on one side of the big end; the side wall of the charging port is communicated with a ventilation duct; the small end is connected with a right-angle rotatable branch smoke pipe; the other end of the right-angle rotatable branch smoke pipe is connected with the fixed branch smoke pipe and can rotate on the fixed branch smoke pipe; and the fixed branch smoke pipe is connected with dust collection equipment. The smoke collection cover has small volume, light weight, simple structure and little negative pressure loss and is convenient to mount and operate; since the smoke collection cover can rotate with the furnace body, continuous dust collection can be realized during the iron adding of a traveling crane and the slag beating of workers without moving the smoke collection cover, the dust collection effect is over 99%, and the working efficiency is high; and moreover, the working environment is effectively improved, and the working sight is obviously improved during the charging of the traveling crane.
Description
Technical field
The utility model relates to the flue dust collecting device in a kind of intermediate frequency furnace cast iron melting process.
Background technology
Intermediate frequency furnace is the capital equipment of cast iron melting, and current electrolysis aluminium industry intermediate frequency furnace commonly used has series such as 1t, 2t, 3t, and every suit intermediate frequency furnace power cabinet in the series is through 2 body of heater work of the switch of falling stove control.Gradually popularize at aluminum electrolysis industry with intermediate frequency furnace melting molten iron, but the flue dust collecting that melting produces never has good solution.
An exhaust fume collecting hood hangs in some enterprise directly over fire door, but when driving adds iron, workman's slag hitting, must intermediate frequency furnace petticoat pipe suitable for reading be removed.Especially intermediate frequency furnace goes out during the molten iron, and body of heater is through 2 supporting cylinders in its underpart, intermediate frequency furnace is revolved around its rotating shaft pour out molten iron after turning 90 degrees, and still needs this moment petticoat pipe is removed.According to the molten 8 stove molten iron of per tour, only reinforced, slag hitting, go out molten iron and just need to move petticoat pipe 24 times, very loaded down with trivial details, and belong to discontinuous and gather dust, dust-collecting efficiency is low.
Summary of the invention
The technical problem that the utility model will solve is: design the device that can collect the intermediate frequency furnace flue dust continuously; Guarantee, slag hitting reinforced, need not move the fire door petticoat pipe during going out molten iron at intermediate frequency furnace; The difficult problem of continuous collection intermediate frequency fire door upper smoke dirt be can solve again, working environment environmental protection more, safety made.
The technical scheme that solution the utility model technical problem is taked is: this device comprises can be with exhaust fume collecting hood, rotatable smoking pipe, the fixing branch smoke pipe of body of heater rotation; Can be a flat tube structure with the exhaust fume collecting hood of body of heater rotation, the big end of an end be little, and a big end is located at the fire door top of intermediate frequency furnace; A big end end is circular; Diameter is identical with the intermediate frequency furnace furnace port diameter, has the feeding port that a diameter is slightly less than the intermediate frequency furnace fire door in the one of which side, and the sidewall of feeding port is communicated with ventilating duct; A little end connects the rotatable smoking pipe of a square; The rotatable smoking pipe other end of square connects a fixing branch smoke pipe, and the rotatable smoking pipe of square is sleeved on the fixing branch smoke pipe, and can on the fixing branch smoke pipe, rotate; The rotatable smoking pipe horizontal ends of square and the axle center of fixing branch smoke pipe and the intermediate frequency furnace rotating shaft core straight line that coexists, the fixing branch smoke pipe connects dust collection equipment; Can be fixed on the working plate of intermediate frequency furnace through support with the exhaust fume collecting hood of body of heater rotation.
Dust collection equipment and control system are the same with conventional deduster control circuit, do not do narration at this.
The good effect of the utility model is: the exhaust fume collecting hood volume is little, in light weight, simple in structure, the loss of convenient installation and operation, negative pressure is few; Because exhaust fume collecting hood can rotate with body of heater, driving adds iron, workman's slag hitting can be gathered dust continuously, does not need the mobile set petticoat pipe to operate, and dust collection effect is more than 99%, and high efficiency; Working environment is effectively improved, and the work sight line had also had remarkable improvement when driving was reinforced.
Description of drawings
Accompanying drawing 1 is the scheme of installation of the utility model on intermediate frequency furnace; Accompanying drawing 2 is vertical views of accompanying drawing 1; Accompanying drawing 3 is the intermediate frequency furnace gas collection system working state schematic representation of the utility model.
The specific embodiment
Like accompanying drawing 1, shown in 2; This device comprises can be with exhaust fume collecting hood 2, rotatable smoking pipe 7, the fixing branch smoke pipe 8 of body of heater rotation; Can be a flat tube structure with the exhaust fume collecting hood 2 of body of heater rotation, the big end of an end be little, and a big end is located at fire door 9 tops of intermediate frequency furnace 1; A big end end is circular; Diameter is identical with intermediate frequency furnace fire door 9 diameters; Have the feeding port 10 that a diameter is slightly less than intermediate frequency furnace fire door 9 in the one of which side, the sidewall of feeding port 9 is communicated with ventilating duct 6, and a little end connects the rotatable smoking pipe 7 of a square; Rotatable smoking pipe 7 other ends of square connect a fixing branch smoke pipe 8; The rotatable smoking pipe 7 of square is sleeved on fixing branch smoke pipe 8, and can on fixing branch smoke pipe 8, rotate, and rotatable smoking pipe 7 horizontal ends of square and the axle center of fixing branch smoke pipe 8 and intermediate frequency furnace rotating shaft 3 axle center coexist on the straight line; Fixing branch smoke pipe 8 connects dust collection equipment 12, and flue dust is discharged (shown in accompanying drawing 3) through air-introduced machine 13 through chimney 11; Can be fixed on the working plate 4 of intermediate frequency furnace 1 through support 5 with the exhaust fume collecting hood 2 of body of heater rotation.
The course of work of the utility model is: before intermediate frequency furnace 1 blow-on, at first start the frequency conversion fan and the electric-control system of deduster 12,1 petticoat pipe valve open of the intermediate frequency furnace that will start again; In stove, add iron then, start the intermediate frequency furnace system, treat intermediate frequency furnace system operation about 90 minutes; After the intermediate frequency furnace molten iron is melting is good; Beginning slag hitting, batching, after the fully dissolving of treating to prepare burden in the stove, rotation intermediate frequency furnace 1 body is poured out molten iron.Because of being fixed on intermediate frequency furnace 1 working plate 4, so whole process can all be collected flue dust continuously with the exhaust fume collecting hood 2 of body of heater rotation, and can not influenced any operation of intermediate frequency furnace 1 above the fire door 9 of intermediate frequency furnace 1 always with the exhaust fume collecting hood 2 of body of heater rotation.
