Description
Technical field
This utility model relates to rotary hearth furnace device for discharging, belongs to mechanical equipment technical field.
Background technology
In field of steel metallurgy, for being reduced directly the rotary hearth furnace of technique mainly by will be by reducing material and iron oxides structure
The raw material become manufactured reduced iron the most originally, and due to the particular/special requirement of this kind of technique so that described rotary hearth furnace is long-term
Carry out operation in high temperature environments, wherein, be provided with for the reduced iron of rotary furnace bottom is given off institute at described rotary hearth furnace
State the screw unloading device of rotary hearth furnace, and the durability of this screw unloading device produces the life of reduced iron for improving rotary hearth furnace
Productivity plays vital effect, plays restrictive link particularly with improving rotary hearth furnace maximization.
For this, the commonly used helical axis discharging of helical axis of existing rotary hearth furnace, inventor finds in research process,
Using a helical axis discharging, not only the cooling-down effect of helical structure is poor, and along with the maximization of rotary hearth furnace, burner hearth width
The increasing of degree, the length of a helical axis has reached the limit, is difficult to improve the length of helical axis again.
Utility model content
Utility model purpose: in order to overcome the deficiencies in the prior art, this utility model provides a kind of rotary hearth furnace discharging
Device, invests low, good cooling effect, and operation and maintenance cost is low, can meet the maximization requirement of rotary hearth furnace.
Technical scheme: for solving above-mentioned technical problem, a kind of rotary hearth furnace device for discharging of the present utility model, including position respectively
In rotary hearth furnace furnace wall and a screw of furnace roof and No. two screws, a described screw and No. two spirals dresses
Putting and all include cylinder, scraper and motor, described cylinder is arranged on rotary hearth furnace by support, and cylinder passes through driven by motor
Rotate, cylinder is provided with scraper.
As preferably, in described cylinder, it is provided with water-cooling channel, in water-cooling channel, is connected with cooling water.
As preferably, a described screw and No. two are equipped with distance adjusting system between screw and rotary hearth furnace,
Ensure that the material on siege all draws off and ensures that scraper does not contacts with siege.
As preferably, described scraper is bolted with cylinder, facilitates the replacing of scraper.
As preferably, the scraper direction of rotation on a described screw and No. two screws is consistent.
Beneficial effect: rotary hearth furnace device for discharging of the present utility model, simple in construction, use water-cooling apparatus, cooling is reliable,
Scraper can be individually replaced, and operation and maintenance cost is low, uses two ends screw discharging, shortens helical axis length,
Good cooling effect, can meet the maximization of rotary hearth furnace.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of a screw.
Detailed description of the invention
A kind of rotary hearth furnace device for discharging of the present utility model, including the spiral dress laying respectively at rotary hearth furnace furnace wall and furnace roof
Put 1 and No. two screws 2, a described screw 1 and No. two screws 2 all include cylinder 4, scraper 3
With motor 6, described cylinder 4 is arranged on rotary hearth furnace by support, and cylinder 4 is driven by motor 6 and rotates, at cylinder
Being provided with scraper 3 on 4, described scraper 3 is bolted with cylinder 4, facilitates the replacing of scraper 3, described scraper 3
Direction of rotation can be shifted material onto outside siege inside siege, on a screw 1 and No. two screws 2
Scraper 3 direction of rotation is consistent.
In this utility model, it is provided with water-cooling channel in described cylinder 4, in water-cooling channel, is connected with cooling water, water-cooling channel
By water pipe 5 conveying cooling water.Be equipped with between a described screw 1 and No. two screws 2 and rotary hearth furnace away from
From adjusting apparatus, described distance adjusting system is to drive Worm gear feed screw elevator to regulate the support of cylinder by motor
Highly, it is ensured that the material on siege all draws off and ensures that scraper 3 does not contacts with siege.
This utility model in use, inside 1 siege of a screw on material shift onto on outside siege, No. two
Screw 2 is released siege the material on outside siege again and is completed discharging.
The above is only preferred implementation of the present utility model, it should be pointed out that: for the ordinary skill of the art
For personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve
Also protection domain of the present utility model is should be regarded as with retouching.
