Abstract
The invention relates to a rotary-type auger delivery electrode for adding powder in the center of an electric furnace. The rotary-type auger delivery electrode for adding powder in the center of the electric furnace is characterized by comprising a powder bin and a powder delivery pipe installed at a discharge port of the powder bin, wherein the powder delivery pipe is internally provided with an auger delivery shaft which is connected with a delivery motor through a powder bin drive shaft in the powder bin; the powder bin is externally provided with a rotary fixed frame fixedly; and the rotary fixed frame is installed on the rotary fixed shaft and is driven to rotate around a shaft by the rotary fixed shaft. According to the invention, powder is directly delivered to a fusion tank through an auger extrusion delivery mode, because during the delivery process of the powder, the powder is extruded into a delivery pipe about 15m long above, thus a central electrode is sealed, carbon monoxide is prevented from leaking outside, guarantee is provided for the safety of working personnel, meanwhile the halt treatment when the electrode is abnormal is reduced greatly, and the guarantee is provided for continuous production and production efficiency; according to the invention, the moving of the electrode is realized through the arranged rotary device, and thus powder is delivered according to the production requirement; and the rotary-type auger delivery electrode for adding powder in the center of the electric furnace is simple in structure, is safe and reliable, is convenient and flexible in application, implements the effective utilization of the powder, implements the resource recycling, reduces energy source waste and energy consumption, and reduces the environment pollution.
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 powder rotary spiral delivery electrodes.
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 safe and reliable electric furnace center powder rotary spiral delivery electrodes.
For realizing that the technical scheme that the foregoing invention purpose is taked is:
A kind of electric furnace center adds powder rotary spiral delivery electrodes; 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 fixedly mounted on the rotary fixing frame, and this rotary fixing frame is installed on the rotational fixation axle and by its drive and sways.
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.Simultaneously, the present invention also is provided with the rotatable rotary fixed mount and realizes moving of electrode, thereby has realized according to production needs convey materials.Electric furnace of the present invention center adds that powder rotary spiral delivery electrodes is simple in structure, safe and reliable, 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 powder rotary spiral delivery electrodes 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 powder rotary spiral delivery electrodes; 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 fixedly mounted on the rotary fixing frame 6, and this rotary fixing frame 6 is installed on the rotational fixation axle 7.Rotation through rotational fixation axle 7 drives rotary fixing frame 6 rotations and moves, thereby it is mobile to drive the rotation of whole conveyings 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.
