Abstract

The utility model relates to a calcium carbide furnace hollow electrode system power conveyor, consisting of a delivery pipe, a spirochete of motor drive, and two ends transmission supports. The delivery pipe is provided with a feed interface and a discharging interface. The device is characterized in that the delivery pipe inner surface of the conveyor and a rotator blade surface are coated with a layer of cemented carbide, or the delivery pipe is made by cemented carbide casting method to enhance abrasion resistance. The conveyor uses two layers seal structure at the two ends support seats of the delivery pipe. A gas channel is arranged between the two layers seal structure. The channel is filled with nitrogen whose pressure is a little higher that the pressure in the conveyor, with the carbon monoxide in the conveyor being prevented from permeating outside. The conveyor uses calcium carbide furnace hollow electrode system, with simple structure, long service life, good seal performance, which creates good condition for ensuring normal production of the calcium carbide furnace.

Description

Furnace of calcium carbide coreless armature system powder conveyer
[technical field] the utility model relates to a kind of furnace of calcium carbide coreless armature system powder conveyer, and this conveyer belongs to a kind of furnace charge conveying device.
[background technology] is present, and domestic iron and steel metallurgical industry and furnace of calcium carbide generally adopt powder conveyor delivery coke and lime powder in producing.In carrying the powder process, because coke to conveyer shell and conveyor screw serious wear, makes that existing conveyer is shorter service life; In addition, existing powder conveyer is carried powder with nitrogen as carrier, and the CO gas in the stove is sneaked in the conveyer by the hollow tube of coreless armature easily, causes the interior CO gas of stove excessive, has influenced furnace of calcium carbide and has normally kept the safety in production.
[summary of the invention] the purpose of this utility model is to provide a kind of furnace of calcium carbide coreless armature system powder conveyer, and this conveyer has characteristics such as anti-wear performance height, good seal performance.
The utility model above-mentioned purpose realizes by following technological means.
A kind of furnace of calcium carbide coreless armature system powder conveyer, the driving support seat that comprises carrier pipe, motor-driven conveyor screw and two ends, carrier pipe is provided with charging interface and discharging interface, it is characterized in that the carrier pipe inner surface of said conveyer and the blade surface of rotary body are coated with hard alloy layer, to increase its wearability.Less when the carrier pipe inner surface diameter, when being difficult to the coated with hard alloy-layer, can directly adopt the carbide alloy forging type, solve the carrier pipe wearability.
In addition, on two end bearings of carrier pipe, this conveyer has adopted air seal structure.Air seal structure adopts double-layer sealing structure, is arranged on the conveyor screw two end supports axle.Be provided with gas passage between the above-mentioned double-layer sealing structure, be connected with nitrogen in the passage, a little higher than powder conveyer of nitrogen gas pressure internal pressure is revealed the outside to stop CO gas in the conveyer to ooze.
The conveyer that the utility model provides is used for furnace of calcium carbide coreless armature system, has advantages such as simple in structure, long service life, good airproof performance, is to guarantee the furnace of calcium carbide ordinary production, has created good condition.Above-mentioned powder conveyer is also applicable to other coreless armature system.
[description of drawings] introduces the utility model specific embodiment in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model conveyor construction schematic diagram.
Fig. 2 is the utility model conveyer driving support seat profile
[specific embodiment] conveyer that present embodiment provided, its structure as shown in Figure 1.This conveyer comprises carrier pipe 3, is assemblied in the driving support seat 2 and the bearing block 1 at conveyor screw 4 two ends, motor 7 drives conveyor screw 4 by shaft coupling 6, carrier pipe 3 is provided with charging interface 5 and discharging interface 8, and carrier pipe 3 inner surfaces of conveyer and the blade surface of rotary body 4 are coated with one deck carbide alloy.Less when carrier pipe 3 inner surface diameter, when being difficult to the coated with hard alloy-layer, can directly adopt the carbide alloy forging type to make carrier pipe.The driving support seat 2 at this conveyer conveyor screw 4 two ends is provided with Double layer packing hermetically-sealed construction 10, and packing is arranged in the housing 12 of hermetically-sealed construction 10, and housing 12 1 ends of hermetically-sealed construction 10 are equipped with gland 9.Be provided with gas passage 11 between the above-mentioned double-layer sealing structure 10, be connected with nitrogen in the passage, a little higher than powder conveyer of nitrogen gas pressure internal pressure is revealed the outside to stop CO gas in the conveyer to ooze.
