Abstract
The utility model, which belongs to the mechanical equipment field, discloses an electrode guiding device of an ore-smelting electric furnace. The guiding device comprises a furnace cover, electrode guide wheels arranged on the furnace cover, an electrode holder, and a guide rail arranged at the electrode holder. According to the scheme, the electrode guide wheels and the guide rail are arranged to carry out positioning and guiding on the electrode, so that the overlap ratio of the compression platform center line and the electrode holder center line is improved. The electrode oscillation amplitude is controlled and the electrode inclination generated by nonuniform material placing can be reduced, so that the electrode oscillation amplitude and inclination are effective reduced. The collision between the electrode and the furnace cover is prevented; the fault rates of the electrode system and the furnace cover are reduced and the service lives of the electrode system and the furnace cover are prolonged; the labor intensity and the repairing cost of the equipment maintenance staff are also reduced.
Description
Technical field
The utility model relates to plant equipment field, particularly a kind of ore-smelting electric furnace electrode guide.
Background technology
Electrode system is the core component of 33MVA ore-smelting electric furnace.Electrode system mainly comprises electrode, electrode holde, Electrode Fluctuation Device, electrode lifting device.33MVA ore-smelting electric furnace electrode system is only provided with guider at 19.5m platform, downward from 19.5m platform, and electrode holde adds the about 13m of paste column length that inserts mineral aggregate, after putting into production, has following shortcoming:
1. the amplitude of oscillation is large, makes to press platform center line and does not overlap with holder center line, presses not in place.
2. the amplitude of oscillation is large, and brasses and pressure rings are easily beaten arc; Electrode column easily and after bell collision makes bell produce the voltage that exceedes safe voltage, bell failure of insulation.
3., when cloth is inhomogeneous, be subject to after furnace charge extruding, electrode incline, the skew of utmost point heart circle is large, and electric energy loss increases; While pressing with lifting and the sealing collision of the electrode of bell, cause bell to cave in.
Summary of the invention
In order to solve the problem of prior art, the utility model embodiment provides a kind of failure rate that has reduced electrode system and bell, extend the useful life of electrode system and bell simultaneously, reduce plant maintenance personnel's labour intensity, the ore-smelting electric furnace electrode guide of the cost of overhaul.Described technical scheme is as follows:
The utility model embodiment provides a kind of ore-smelting electric furnace electrode guide, and described ore-smelting electric furnace electrode guide comprises bell, be arranged on electrode directive wheel, electrode holde on described bell, be arranged on the guide rail on described electrode holde.
Particularly, described directive wheel is installed on described bell, between described directive wheel and described bell, is provided with the micarex that 10mm is thick.
Particularly, described guide rails assembling is on described electrode holde, and one end is fixed in pressure rings, and the other end is fixed on carrying cylinder.
Particularly, between described guide rail and described pressure rings, described guide rail and described carrying cylinder, be equipped with the mica insulation plate that 10mm is thick.
Particularly, the I-steel that described guide rail is stainless steel is made.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
By electrode directive wheel and guide rail are set, electrode is positioned and led, to improve the registration that presses platform center line and electrode holde center line, the control electrode amplitude of oscillation, the gradient producing while reducing electrode due to cloth inequality, reduces the electrode amplitude of oscillation and gradient effectively, prevent electrode and bell collision, reduce the failure rate of electrode system and bell, extended the useful life of electrode system and bell simultaneously, reduced plant maintenance personnel's labour intensity, the cost of overhaul.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the ore-smelting electric furnace electrode guide that provides of the utility model embodiment.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model execution mode is described in further detail.
Embodiment
The utility model embodiment provides a kind of ore-smelting electric furnace electrode guide, and referring to Fig. 1, described ore-smelting electric furnace electrode guide comprises bell, be arranged on electrode directive wheel 1, electrode holde on bell, be arranged on the guide rail 2 on electrode holde.
Particularly, directive wheel 1 is installed on bell crossbeam, between directive wheel and bell crossbeam, is provided with the micarex that 10mm is thick, guarantees that between directive wheel and bell crossbeam, insulation is reliable.
Particularly, guide rail 2 is installed on electrode holde, and one end is fixed in pressure rings, and the other end is fixed on carrying cylinder; Between guide rail and pressure rings, guide rail and carrying cylinder, be equipped with the mica insulation plate that 10mm is thick, guarantee mutually insulated between each member.
Preferably, the I-steel that guide rail 2 is stainless steel is made, with high temperature resistant.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
By electrode directive wheel and guide rail are set, electrode is positioned and led, to improve the registration that presses platform center line and electrode holde center line, the control electrode amplitude of oscillation, the gradient producing while reducing electrode due to cloth inequality, reduces the electrode amplitude of oscillation and gradient effectively, prevent electrode and bell collision, reduce the failure rate of electrode system and bell, extended the useful life of electrode system and bell simultaneously, reduced plant maintenance personnel's labour intensity, the cost of overhaul.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
