Description
Technical Field
The utility model relates to the technical field of blast furnaces, in particular to a blast furnace taphole mud cover cleaning drill bit.
Background
The blast furnace taphole is provided with the mud cover, and the tapping can erode the mud cover in the production, erodes for a long time and will lead to the bore grow, consequently need do the mud cover again, can satisfy normal production. However, in a production period, mud sleeves are usually required to be manufactured on line for 2-3 times, 4 workers are required to clean the old tap hole mud sleeves to form holes with the diameter of 250mm and the thickness of 100mm by using a large hammer drill rod when the mud sleeves are manufactured each time, the operation time is 2 hours, the construction complexity is high, and the efficiency is low. Meanwhile, manual operation causes non-uniform standards, which causes unstable quality of mud hole rework and affects service life.
SUMMERY OF THE UTILITY MODEL
The utility model provides a blast furnace taphole mud cover clearance drill bit solves the technical problem that the blast furnace taphole mud cover clearance operation is complicated, and is inefficient in the prior art.
In order to solve the technical problem, the utility model provides a blast furnace taphole mud cover clearance drill bit, include: the grinding disc, and a drilling tool connecting part and a purging window which are arranged on the grinding disc;
the drilling tool connecting part is arranged on the first disc surface of the grinding disc, and the second disc surface of the grinding disc is provided with a grinding structure;
and teeth for grinding are arranged on the side wall of the grinding disc.
Further, the drilling tool connecting part is a regular polygon groove formed in the second disc surface.
Further, the purge window is disposed on a center of the abrasive disc.
Furthermore, a reinforcing rib is arranged on the second disc surface.
Further, the reinforcing ribs are arranged on the teeth and the second disk face.
One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:
the blast furnace tap hole mud cover clearance drill bit that provides in this application embodiment realizes the synchronous grinding of large tracts of land respectively through mill face and tooth, under the condition of cooperation rig, can reduce work complexity and intensity of labour by a wide margin, promotes work efficiency. Meanwhile, a unified operation specification can be formed, and the service life is prolonged.

FIG. 2 is a sectional view of a blast furnace taphole mud sleeve cleaning drill provided by the embodiment of the utility model.
Detailed Description
The embodiment of the application provides a blast furnace taphole mud cover clearance drill bit, solves the technical problems of complex taphole mud cover clearance operation and low efficiency in the prior art.
In order to better understand the technical solutions, the technical solutions will be described in detail below with reference to the drawings and the specific embodiments of the present disclosure, and it should be understood that the specific features in the embodiments and examples of the present disclosure are detailed descriptions of the technical solutions of the present disclosure, but not limitations of the technical solutions of the present disclosure, and the technical features in the embodiments and examples of the present disclosure may be combined with each other without conflict.
Referring to fig. 1 and 2, a blast furnace taphole mud jacket clearing bit comprises: the grinding disc 1, and a drilling tool connecting part 3 and a purging window 4 which are arranged on the grinding disc 1.
The drilling tool connecting part 3 is arranged on a first disc surface of the grinding disc, and a grinding structure is arranged on a second disc surface of the grinding disc 1; generally, the grinding structure can be an undulating raised line or raised teeth.
In order to increase the destructive force, the side walls of the grinding disc 1 are provided with teeth for grinding, i.e. in the radial direction.
In this embodiment, the drilling tool connecting part 3 is a regular polygon groove formed on the second disc surface; the quick-dismounting connector is used for quick dismounting and can be other connectors of other adaptive drilling machines.
Further, the blowing window 4 is arranged in the center of the grinding disc 1, and chips are blown by an external air source.
In order to strengthen the function of the grinding disc, the second disc surface is provided with reinforcing ribs 2, and a high-strength alloy steel structural member with high temperature resistance is generally adopted.
Further, the reinforcing ribs 2 are arranged on the teeth and the second disk surface, and reliability of the teeth is guaranteed.
One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:
the blast furnace tap hole mud cover clearance drill bit that provides in this application embodiment realizes the synchronous grinding of large tracts of land respectively through mill face and tooth, under the condition of cooperation rig, can reduce work complexity and intensity of labour by a wide margin, promotes work efficiency. Meanwhile, a unified operation specification can be formed, and the service life is prolonged.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
