Technical Field
The utility model belongs to the field of swirling ponds of continuous casting machines, and particularly relates to a filtering device for collecting scale of a swirling well of a continuous casting machine.
Background
In the process of forming molten steel by a continuous casting machine, the surface of a steel billet can be oxidized to generate a large amount of oxidized iron scales. At the same time, a considerable amount of mold flux residue (about 0.5kg/t of steel for slab mold flux) was mixed into the iron scale, and this mixture was called iron scale residue. When the billet in the existing process is subjected to the steps of secondary cooling spraying, equipment cooling flushing, residue flushing and the like, the iron slag and the casting powder residues on the outer surface of the billet are flushed away from the slag flushing ditch together and enter a terminal slag basin.
In the mixture of the iron slag and the protecting slag, the protecting slag usually only accounts for 20-40% of the residue, the content of the total iron TFe accounts for about 40-60%, although substances with low melting point such as Na 2O、K2O、CaF2、B2O3 and the like exist in the residue, the iron slag in the residue cannot be directly used as an iron-making raw material according to related standard requirements, but the separated iron slag still has a certain economic value through separating the protecting slag from the iron slag.
However, in the current molten steel continuous casting system, the iron slag is directly flushed into the slag basin. And sedimentation effect of the cyclone pool for sediment is poor, the water flow rotating in the cyclone pool enables iron slag to be precipitated effectively, the grab bucket for fishing the slag above the cyclone pool is used for fishing the slag, the quantity of the fished iron slag is still not large although the slag is fished frequently, and due to poor sedimentation effect, part of iron slag can be directly brought into a circulating water system pipeline and a sewage treatment facility device, the burden of a filtering device is aggravated, the service life of the device is shortened, meanwhile, the water quality is seriously exceeded, the water quantity for sewage disposal can only be increased, and the waste of water resources is caused.
Therefore, a new design is needed that can effectively delay and collect the iron slag without changing the basic structure of the cyclone tank.

Detailed Description
The utility model is further described below in connection with specific embodiments.
Example 1
As shown in fig. 1 and 2, the main body of the utility model is a filtering iron cage 3, and the filtering iron cage 3 is a circular net cage with the size slightly smaller than that of a wellhead 1, and can be directly put into a well from the inner side of the wellhead 1.
In a cyclone well system, a well head 1 is usually preset at the central part of the cyclone well, so that a grab bucket can conveniently penetrate into the bottom of the cyclone well from the well head 1, the position of the well head 1 is just aligned with the position of the bottom for sediment accumulation, and the grab bucket can directly grab waste residues from the sediment accumulation.
The upper part of the filtering iron cage 3 is of an opening structure, the bottom of the filtering iron cage is of a closed structure, and normal grabbing work of the filtering iron cage is not hindered when the grab bucket grabs waste materials. And to piling up the waste residue at the corner and can directly hang the filtration iron cage 3 when overhauing and clear up, to the lowering and lifting of filtration iron cage 3, be provided with a plurality of lifting hooks 2 in the top of filtration iron cage 3, be convenient for hoist and mount filtration iron cage 3.
The height of the filtering iron cage 3 is higher than the distance between the bottom of the wellhead 1 and the bottom of the cyclone well, so that the phenomenon that iron slag with smaller mass cannot be precipitated is avoided, the iron slag floats up to the water surface under the drive of water flow and flows into the water outlet 5 of the cyclone well, the iron slag enters the circulating water system, and the work load of the filtering device of the circulating water system is increased.
The slag inlet 6 of the filtering iron cage 3 in this embodiment is set to be a whole larger slag inlet, the width of the slag inlet 6 is about one fourth of the whole filtering iron cage 3, and the height is the same as that of the filtering iron cage 3.
The filtering iron cage 3 with the structure is suitable for a cyclone well structure that the cyclone well water inlet 4 can directly impact the filtering iron cage 3, so that the slag inlet 6 of the filtering iron cage 3 is required to be installed towards the cyclone well water inlet 4 during installation, water flow entering a cyclone tank can be firstly flushed into the filtering iron cage 3, and the filtering iron cage 3 filters and precipitates iron slag.
Example 2
