Abstract
The utility model relates to a hollow electrode powder conveying device of a calcium carbide furnace. The hollow electrode powder conveying device comprises a hollow electrode, wherein a central electrode tube is mounted in the hollow electrode; the upper end of the central electrode tube is communicated with a powder storage bin through a work power bin and a powder conveying pipe; and a central push rod capable of doing reciprocating motion is mounted in the central electrode tube. According to the hollow electrode powder conveying device provide by the utility model, the mechanical push rod continuously squeezes powder down into a high-temperature region of the calcium carbide furnace, thus avoiding accidents of carbon monoxide leakage caused by nitrogen conveyance. The hollow electrode powder conveying device of the calcium carbide furnace can effectively deal with a large amount of powder generated in calcium carbide production, so that industrial waste is comprehensively utilized inside a factory; and the hollow electrode powder conveying device has the characteristics of energy conservation, environment pollution reduction, safety and reliability.
Description
Technical field
The utility model relates to furnace of calcium carbide smelting equipment technical field, particularly relates to a kind of furnace of calcium carbide hollow electrode powder transport.
Background technology
In the calcium carbide production process, a large amount of powders are gone into stove and can be caused 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.Usually the way of taking is that 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 nitrogen is carried the powder mode, be easy to cause carbon monoxide to leak, potential safety hazard is big.
Summary of the invention
The purpose of the utility model is to overcome the defective of above-mentioned prior art, and a kind of powder of effectively utilizing in the calcium carbide production is provided, and energy savings reduces environmental pollution, and safe and reliable furnace of calcium carbide hollow electrode powder transport.
For realizing that the technical scheme that the foregoing invention purpose is taked is:
A kind of furnace of calcium carbide hollow electrode powder transport; Comprise coreless armature; It is characterized in that: the electrode centers pipe is installed in the said coreless armature; This electrode centers pipe upper end is communicated with powder storage bin through work filler bin, powder conveying pipe, and reciprocating center push rod is installed in the electrode centers pipe;
Center-pole umbrella shape lobe is installed on the said center push rod;
The upper end of said center push rod is equipped with reciprocating oil cylinder or reciprocating air cylinder;
The upper end of said center push rod is provided with steel pipe spreading servicing unit.
The utility model utilizes the mechanical type push rod that powder constantly is squeezed in the furnace of calcium carbide high-temperature region downwards, thereby has stopped to adopt nitrogen to carry the generation of the carbon monoxide leakage accident that brings.
The furnace of calcium carbide hollow electrode powder transport of the utility model can effectively solve a large amount of powders that produce in the production of power down stone, makes trade waste obtain comprehensive utilization in inside plants, has energy savings, reduces environmental pollution, safe and reliable characteristics.
The device of the utility model can consume the 15-20% powder every day, presses the 30000KVA furnace of calcium carbide and calculates 180 tons of calcium carbides of daily output, can consume 32 tons of powders every day, and powder per ton on average can be practiced thrift nearly 40,000 yuan by 1200 yuan of every days.
Description of drawings
Fig. 1 is the structural representation sketch of the utility model furnace of calcium carbide hollow electrode powder transport;
Fig. 2 is the enlarged drawing at A position among Fig. 1.
The specific embodiment
The furnace of calcium carbide hollow electrode powder transport of the utility model comprises hollow electrode 1, and this hollow electrode 1 is inserted in the furnace of calcium carbide 9.One electrode centers pipe 2 is installed in the center cavity of hollow electrode 1, and the top of electrode centers pipe 2 is equipped with work filler bin 3, and work filler bin 3 is communicated with powder storage bin 5 through the set powder conveying pipe 4 of sidepiece.In electrode centers pipe 2, be provided with center push rod 6, this center push rod 6 is reciprocating through its end set reciprocating oil cylinder or reciprocating air cylinder 8.On center push rod 6, also be provided with simultaneously several center-pole umbrella shape lobes 7.
During use, powder 4 is sent into work filler bin 3 from powder warehouse 5 along powder delivering pipe, and meanwhile, center push rod 6 is reciprocating under the powered of reciprocating oil cylinder or reciprocating air cylinder 8, thereby powder is sent constantly in the furnace of calcium carbide 9.The interval of center push rod reciprocating action, cloth length can be adjusted according to the process conditions of furnace of calcium carbide and the condition of powder in the utility model.For this reason, be provided with steel pipe spreading servicing unit 10 in the end of center push rod 6.
