Abstract
The utility model relates to a kind of overflow combined type slags, lead chute, belong to technical field of metallurgical equipment, the overflow combined type slag, lead chute include leading portion slot, back segment slot, middle overflow device, leading portion slot, back segment slot, middle overflow crust of the device are formed by fire resisting brick masonry, middle overflow device is internally provided with the groove that can accommodate lead liquid, and it is whole that leading portion slot, middle overflow device and back segment slot are sequentially connected composition chute.The utility model structure is simple, and installation builds simple, and effective solution is because the chute gradient is excessive, the too fast damage to lead chute of flow velocity, long service life.
Description
Technical field
The utility model relates to technical field of metallurgical equipment, and in particular to a kind of overflow combined type slag, lead chute.
Background technique
Modern pyrometallurgical smelting process, yield is big, and melting cycle is short, high to the frequency of use of slag, lead chute, in high-temperature slag
High temperature is easy to produce when flowing through chute to wash away to corroding chute, it is excessively high and refractory brick uses unreasonable feelings in frequency of use
Condition greatly shortens the service life of chute, to increase maintenance cost, influences the whole production time, reduces metallurgical furnace kiln
Production efficiency.
Summary of the invention
The problem of for background technique, the utility model proposes a kind of overflow combined type slags, lead chute, effectively
Solve because the chute gradient is excessive, the too fast damage to lead chute of flow velocity, effectively prolong the service life.
To achieve the above objectives, the present invention adopts the following technical solutions: the overflow combined type slag, lead chute include
Leading portion slot, back segment slot, middle overflow device, leading portion slot, back segment slot, middle overflow crust of the device are formed by fire resisting brick masonry,
Middle overflow device is internally provided with the groove that can accommodate lead liquid, and leading portion slot, middle overflow device and back segment slot are sequentially connected
It is whole to form chute.
Preferably, leading portion slot setting angle is 9-15 degree.
Preferably, back segment slot setting angle is angle 3-7 degree.
Preferably, middle overflow device adjusts height according to the length and flow velocity of leading portion slot and back segment slot.
The utility model has the beneficial effects that
The utility model structure is simple, and installation builds simple, and effective solution is because the chute gradient is excessive, flow velocity is too fast right
The damage of lead chute, long service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 3- leading portion slot, 4- back segment slot, 5- middle overflow device.
Specific embodiment
In order to keep the purpose of this utility model, technical scheme and beneficial effects clearer, below in conjunction with attached drawing, to this
The preferred embodiment of utility model is described in detail, to facilitate the technical staff to understand.
As shown in Figure 1, the overflow combined type slag, lead chute include leading portion slot 3, back segment slot 4, middle overflow device 5, it is preceding
Section slot 3, back segment slot 4,5 shell of middle overflow device are formed by fire resisting brick masonry, leading portion slot 3, middle overflow device 5 and back segment
It is whole that slot 4 is sequentially connected composition chute.Wherein, leading portion slot 3 is drained to middle overflow device 5, and setting angle is 9-15 degree, subtracts
The gradient of few chute, reaches the flow velocity for slowing down slag, lead, reduces damage of the melt to chute.Middle overflow device 5 connects leading portion slot
3 and back segment slot 4, middle overflow device be internally provided with the groove that can accommodate lead liquid, by overflow adjustable way, slow down
The flow velocity of slag, lead reduces the damage of slag, lead to chute；Also, middle overflow device 5 can be according to the length of leading portion slot and back segment slot
Degree and flow velocity adjust height, rationally control the gradient of slot up and down, play the role of forming a connecting link, and extend entire chute uses the longevity
Life.Back segment slot 4 can be drained to active region from intermediate overflow mechanism 5, and setting angle is angle 3-7 degree, can be produced according to scene
Product operation area space, rationally control height and the gradient, reduce slag to the damage of refractory brick, avoid making slag, lead because flow velocity is too fast
It flow to outside active region.
The course of work of the utility model: lead liquid flows into leading portion slot 3 by lead outlet position, and draining by leading portion slot 3 will
Lead liquid imports middle overflow device 5, flow to back segment slot after then lead liquid is filled in middle overflow device 5 by way of overflow
4, active region is finally drained to by back segment slot 4.
Finally, it is stated that preferred embodiment above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, to the greatest extent
Pipe has been described in detail the utility model by above preferred embodiment, but those skilled in the art should manage
Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details
The range of restriction.
