Abstract
The utility model relates to an electric furnace center powder-feeding rotating spiral conveying electrode characterized by comprising a powder bin and a powder conveying pipe arranged on a blanking mouth of the powder bin. A spiral conveying shaft is arranged in the powder conveying pipe, and connected with a conveying motor through a bin transmission shaft in the powder bin. A rotating fixing frame is fixedly arranged outside the powder bin, installed on a rotating fixing shaft, and driven to rotate around the shaft through the rotating fixing shaft. During conveying, the power is extruded in the conveying pipe about 15 meters, so central electrode is sealed, leakage of carbon monoxide is avoided, safety of workers is ensured, halt treatment is greatly reduced when the electrode is abnormal, and continuous production and improvement of production efficiency are ensured. A rotating device is arranged to achieve movement of the electrode, so materials can be conveyed according to production requirements. The electric furnace center powder-feeding rotating spiral conveying electrode is simple in structure, safe and reliable, and convenient and flexible to apply, achieves efficient use of the powder, achieves recycle of resources, lowers waste and consumption of energy, and reduces environment pollution.
Description
Technical field
The utility model relates to the mine heat furnace smelting equipment technical field, particularly relates to a kind of electric furnace center and adds powder rotary spiral delivery electrodes.
Background technology
In the calcium carbide production process, a large amount of powders enter mineral hot furnace and can cause the charge level gas permeability poor, and the working of a furnace worsens, and thorn fire and the material splash of collapsing increase, and charge level is rubescent, the problem such as lift on the electrode, and are therefore very high for 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 by the coreless armature technology, and powder is directly inputted bath by coreless armature, and the 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 large.
Summary of the invention
The purpose of this utility model is to overcome the defective of above-mentioned prior art, and a kind of effective utilization that realizes powder is provided, thus energy savings, environmental contamination reduction, and safe and reliable electric furnace center powder rotary spiral delivery electrodes.
For realizing that the technical scheme that above-mentioned utility model 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 described powder delivering pipe, this screw conveyor shaft is connected with carrying motor by the feed bin power transmission shaft in the filler bin; Described filler bin is fixedly mounted on the rotary fixing frame, and this rotary fixing frame is installed on the rotation fixed axis and by its drive and sways.
On the described feed bin power transmission shaft feed bin capstan bar is installed.
On the described feed bin power transmission shaft self-aligning ball bearing is installed.
The utility model utilizes the screw extrusion mode of movement that powder directly is delivered to the molten bath; because powder is in course of conveying; be 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 greatly reduced simultaneously when electrode is undesired is processed, for the raising of serialization production and production efficiency provides guarantee.Simultaneously, the utility model also arranges the movement that rotatable rotary fixing frame is realized electrode, thereby has realized according to the need of production convey materials.It is simple in structure, safe and reliable that electric furnace of the present utility model center adds powder rotary spiral delivery electrodes, uses convenient, flexiblely, realized effective utilization of powder, realized the recycling of resource, reduced the energy waste energy consumption, reduced environmental pollution.
Description of drawings
Fig. 1 is the structural representation sketch that the utility model electric furnace center adds powder rotary spiral delivery electrodes;
Fig. 2 is the schematic diagram that electrode rotary moves in the utility model.
The specific embodiment
Electric furnace of the present utility model center adds powder rotary spiral delivery electrodes, comprise filler bin 1, described 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 described 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 rotation fixed axis 7.By rotation driven rotary fixed mount 6 rotary movings of rotation fixed axis 7, thereby drive whole conveying electricity level rotary moving.Also be provided with level-sensing device 12 in the filler bin 1, have simultaneously material level peep hole 13 and lower material level peep hole 14 on its sidewall, be used for powder is monitored.
