Abstract
The invention relates to a moveable spiral conveying electrode for adding powder to the center of an electric furnace. The moveable spiral conveying electrode comprises a powder cabin and a powder conveying pipe which is mounted at a blanking port of the powder cabin, wherein a spiral conveying shaft is arranged in the powder conveying pipe; the spiral conveying shaft is connected with a conveying motor through a powder cabin transmission shaft in the powder cabin; the powder cabin is moveably mounted on a moveable bracket; and a moveable screw rod which is driven to move in a parallel form by a moveable speed reducer is fixedly mounted on the powder cabin. The moveable spiral conveying electrode for adding the powder to the center of the electric furnace provided by the invention has a simple structure, is safe and reliable and is convenient and flexible to apply; the effective utilization of the powder is realized; the reutilization of the resource is realized; the energy waste and the energy consumption are reduced; and the environmental pollution is reduced.
Description
Technical field
The present invention relates to the mine heat furnace smelting equipment technical field, particularly relate to a kind of electric furnace center and add the portable helical feed electrode of powder.
Background technology
In the calcium carbide production process, a large amount of powders get into the hot stove in ore deposit and can cause the charge level gas permeability poor, and the working of a furnace worsens, and the thorn fire increases with the material splash of collapsing, and charge level is rubescent, problem such as lift on the electrode, and are therefore very high for the composition and the granularity requirements of furnace charge.Therefore, common way is: powder is sieved, so cause the waste of ample resources, and environmental pollution is serious.At present, up-to-date technology is that powder is directly imported bath through coreless armature through the coreless armature technology, and this method has successfully solved powder and polluted and the waste problem.But because this process employing is that gas is carried the powder mode, be easy to cause carbon monoxide to leak, potential safety hazard is big.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned prior art, a kind of effective utilization that realizes powder is provided, thereby energy savings reduces environmental pollution, and the portable helical feed electrode of safe and reliable electric furnace center powder.
For realizing that the technical scheme that the foregoing invention purpose is taked is:
A kind of electric furnace center adds the portable helical feed electrode of powder; It is characterized in that: comprise the powder delivering pipe that install at material powder storehouse and feed opening place thereof; Be provided with screw conveyor shaft in the said powder delivering pipe, this screw conveyor shaft is connected with carrying motor through the feed bin power transmission shaft in the filler bin; Said filler bin is movably arranged on the traversing carriage, on filler bin, is installed with by mobile reductor and drives parallel mobile mobile screw.
On the said feed bin power transmission shaft feed bin capstan bar is installed.
On the said feed bin power transmission shaft self-aligning ball bearing is installed.
The present invention utilizes the screw extrusion mode of movement that powder directly is delivered to the molten bath; Because powder in course of conveying, is compressed in about carrier pipe more than 15 meters, thereby central electrode is sealed; Prevented leaking outside of carbon monoxide; For staff's safety provides guarantee, the shutdown that has significantly reduced simultaneously when electrode is undesired is handled, for the raising of serialization production and production efficiency provides guarantee.The present invention also utilizes set mobile screw and traversing carriage to realize moving of electrode, thereby has realized according to production needs convey materials.It is simple, safe and reliable that electric furnace of the present invention center adds the portable helical feed electrode structure of powder, and convenient in application is flexible, has realized effective utilization of powder, has realized the utilization again of resource, has reduced the energy waste energy consumption, has reduced environmental pollution.
Description of drawings
Fig. 1 adds the structural representation sketch of the portable helical feed electrode of powder for electric furnace of the present invention center;
The sketch map that Fig. 2 moves for electrode rotation among the present invention.
The specific embodiment
Electric furnace of the present invention center adds the portable helical feed electrode of powder; Comprise filler bin 1, said filler bin conveniently is designed to conical bottom for blanking, and the top of filler bin 1 has powder import 10; The bottom has discharging opening, and the discharging opening place is installed with powder delivering pipe 2.Be provided with screw conveyor shaft 3 in the said powder delivering pipe 2, this screw conveyor shaft 3 is fixed on the feed bin power transmission shaft 4 in the filler bin 1, and feed bin power transmission shaft 4 is by conveying motor 5, reductor 11 driven rotary of filler bin 1 outside.In order to adjust the position of feed bin power transmission shaft 4 and screw conveyor shaft 3, guarantee the normal conveying of powder, in feed bin power transmission shaft 4 upper ends self-aligning ball bearing 9 is set.Feed bin capstan bar 8 also is installed on the feed bin power transmission shaft 4, and purpose is to preventing the powder caking, guaranteeing the powder smooth delivery of power.Filler bin 1 is movably arranged on and moves on the fixed mount 6; Also be fixed with mobile screw 7 on the filler bin 1; Mobile screw 7 drives translation ((specifically: installation and moving track 620 on the output shaft that moves reductor 615 by moving reductor 18; Mobile screw 67b moves around on moving track 620, and moving track 620 is installed in and moves on the wheel 619), thus drive the translation of whole conveying electricity level.Also be provided with level-sensing device 12 in the filler bin 1, have material level peep hole 13 and following material level peep hole 14 on its sidewall simultaneously, be used for powder is monitored.
Powder delivering pipe 2 can be several connections according to the height adjustment that is provided with of filler bin 1 usually, and connecting portion installs powder delivering pipe cover 16 additional, and powder delivering pipe cover 16 is clamped by the tight sleeve pipe 17 of material pipe clamp and installs, and loose gland 15 seals connecting portion.
