Abstract
The invention discloses a discharging structure of a cupola. The discharging structure of the cupola comprises a stream opening formed in a hearth of the cupola and an overflowing pool defined by carbon bricks. The overflowing pool is provided with an overflowing cavity. The stream opening is communicated with the overflowing cavity and is located in the upper portion of the overflowing cavity. An overflowing opening is formed in the lower portion of the overflowing pool and is located above a fixed chute of the cupola, and the overflowing opening is communicated with the overflowing cavity. By the adoption of the discharging structure of the cupola, the flowing speed of a stream is low, large impact on a centrifugal machine is avoided, and damage to the stream opening is reduced.
Description
Technical field
The present invention relates to a kind of discharging structure of furnace cupola, belong to furnace cupola technical field.
Background technology
At present, the direct head piece of the general employing of furnace cupola head piece that existing rock wool produces flows out through fixed chute, again by movable chute to centrifuge, the head piece shortcoming of this pattern is that heat insulation effect is not good, while putting molten iron, stream strand solidifies at every turn, need to dredge with oxygen airduct, time-consuming length and the infringement of convection current thigh mouth are larger.
Summary of the invention
Technical problem to be solved by this invention is the defect that overcomes prior art, and a kind of discharging structure of furnace cupola is provided, and its stream plume speed is slower, has avoided centrifuge to cause greater impact, has reduced the infringement of convection current thigh mouth simultaneously.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of discharging structure of furnace cupola, it comprises out the stream thigh mouth on cupola crucible and the run-off that adopts carbon brick to surround, run-off has spill cavity, a stream strand mouth is communicated with spill cavity, and be positioned at the top of spill cavity, have the overfall being positioned at above furnace cupola fixed chute in the bottom of run-off, this overfall is communicated with spill cavity.
Further, described overfall becomes up big and down small " V " type structure.
Adopt after technique scheme, a stream strand mouth stream thigh out need to be full of after run-off, flow into fixed chute, the setting of run-off, just makes to flow plume speed slower again, avoid the greater impact to centrifuge, meanwhile, after putting molten iron, stream strand can be slowly by the slag fusing of solidifying in run-off, again flow, reduced the infringement of oxygen airduct convection current thigh mouth.
Accompanying drawing explanation
Fig. 1 is the structural representation of the discharging structure of furnace cupola of the present invention.
The specific embodiment
For content of the present invention is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation below,
As shown in Figure 1, a kind of discharging structure of furnace cupola, it is characterized in that: it comprises out the stream thigh mouth 1-1 on cupola crucible 1 and the run-off 2 that adopts carbon brick 2-1 to surround, run-off 2 has spill cavity 2-2, a stream gang mouthful 1-1 is communicated with spill cavity 2-2, and be positioned at the top of spill cavity 2-2, have the overfall 4 being positioned at above furnace cupola fixed chute 3 in the bottom of run-off 2, this overfall 4 is communicated with spill cavity 2-2.
4 one-tenth up big and down small " V " type structures of overfall.
Operation principle of the present invention is as follows:
In the time that in stove, material temperature reaches 1450-1500 ℃, raw material is fused into liquid state and drips gradually, slowly long-pending high in the interior liquid level of cupola well 1, when liquid level reaches stream thigh mouth 1-1, be full of gradually run-off 2, then flow out fibroblast through run-off 2 " V " type mouth, when letting slip after molten iron, a stream burst liquid level raises again, by the recrement fusing in run-off, fibroblast again, even if can not directly melt gradually, as long as oxygen blast a little, can go out stream strand again.
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
Claims (2)
