Abstract
The utility model discloses a furnace cover with repair furnace doors of a sealed calcium carbide furnace and belongs to the field of metallurgical equipment. The furnace cover is distributed around three electrodes, and the surface near the outer side of the furnace cover is respectively provided with a repair furnace door corresponding to each electrode. One edge of each repair furnace door is hinged with the finance cover though a pin shaft, and the periphery of the repair furnace door is fixed to the surface of the furnace cover through a plurality of bolts. After the electrodes have a hard breakage incident, only the bolts on two sides of each repair furnace door are disassembled, the furnace door is opened, and a special tooling appliance is used to directly take out the broken electrode. The manpower and material resources needed by blowing out for repair due to the hard breakage incident of the electrodes are greatly reduced. The furnace cover can be applied to sealed calcium carbide furnaces and sealed furnaces for smelting other alloy varieties. When repair is needed, the repair doors can be opened only in more than 10 minutes. The repair doors can be closed in more than 10 minutes after repair is finished. The repair doors are quick and convenient to open, the closed repair doors are sealed, and the gas in the furnace cover cannot leak.
Description
Technical field
The utility model relates to field of metallurgy, relates in particular to a kind of closed calcium carbide furnace band maintenance fire door bell.
Background technology
At present, in the equipment of furnace of calcium carbide, electrode is exactly heart.In calcium carbide is produced, electric current is exactly to input in stove by electrode, produces electric arc, smelts calcium carbide, and electrode occupies extremely important status in whole electric furnace.And in whole furnace equipment, often can run into soft disconnected, the hard disconnected accident of electrode.Once electrode has an accident, affect electric furnace and normally produce, cause sometimes and stop production several hours or several days, waste a large amount of manpower and materials.
The shutdown maintenance of time, will cause the significant impact of production.As stop one hour, can affect 40% of production capacity, power consumption can increase by 30%, one 31500KVA electric furnace, if maintenance extends the time of 1 hour, can consume 150,000 degree electricity more, and economic loss reaches more than 150,000. moreThe numerous electric furnaces in the whole nation, as adopted technique, at least economize on electricity 1.2 hundred million, reduce economic loss more than 300,000,000.
Utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of bell that overhauls and guarantee the band maintenance fire door that in bell, gas is not revealed for closed calcium carbide furnace fast and easy.
Technical scheme: for achieving the above object, a kind of closed calcium carbide furnace band maintenance fire door bell of the present utility model, this bell is distributed in around 3 electrodes, and corresponding every electrode has 1 maintenance fire door on bell surface in the outer part.
For conveniently fast disassembling maintenance, guarantee the sealing property of fire door simultaneously, one side of described maintenance fire door is hinged by bearing pin and bell, and access door periphery is by some bell surfaces that are bolted to.
Described bell comprises that six are distributed in the fanning strip of described electrode periphery and are located at the star-like plate composition of 3 electrode centers, are flexibly connected between described star-like plate and fanning strip.
When electrode occurs after hard disconnected accident, only need, the Bolt dismantling of maintenance fire door both sides, open fire door, with special machine equipment directly the electrode taking-up of breaking.The manpower and materials required because of electrode hard broken accident shutdown maintenance are greatly reduced.
Beneficial effect:
1, furnace cover of closed type calcium carbide furnace height is lower, observes, safeguards and use when access cover, access door can only be as normal productions.If there is hard disconnected accident in electrode, must first blow electrode for taking out electrode, take out being broken into qualified fragment from inspection door, this maintenance process needs for a long time, and in the time blowing electrode, has a lot of potential safety hazards.Closed calcium carbide furnace band maintenance fire door bell of the present utility model only can be opened access door in more than ten minute in the time that needs overhaul, and overhauls and can close access door in complete more than ten minutes.Open access door rapidly, convenient, close access door airtight, the gas in bell is not revealed.
2, the utility model device structure is uncomplicated, simple to operate, maintenance is easy, cost is not high.The application of this utility model is very extensive, can be applied in closed calcium carbide furnace and smelt the sealed furnace bell of other alloy kinds.After this design application, shorten the repair time of electrode hard breakage fault, avoided the potential safety hazard in the time of explosion electrode.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of closed calcium carbide furnace band maintenance fire door bell of the present utility model, comprises bell body, and this bell is distributed in around 3 electrodes 1, and corresponding every electrode 1 has 1 maintenance fire door 2 on bell surface in the outer part.
For conveniently fast disassembling maintenance, guarantee the sealing property of fire door simultaneously, one side of maintenance fire door 2 is hinged by bearing pin 3 and bell, and access door periphery is by some bell surfaces that are bolted to.
Bell comprises that six star-like plates 5 that are distributed in the fanning strip 4 of electrode periphery and are located at 3 electrode 1 centers form, and are flexibly connected between star-like plate and fanning strip.
When electrode 1 occurs, after hard disconnected accident, only need, the Bolt dismantling of maintenance fire door 2 both sides, opening fire door, with special machine equipment directly the electrode taking-up of breaking.The manpower and materials required because of electrode hard broken accident shutdown maintenance are greatly reduced.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
