Background
The blast furnace taphole is often impacted by external forces such as a taphole drilling machine, a clay gun machine and the like in the production process, the temperature change is severe, and the slag iron is seriously scoured and eroded on refractory materials, so that the blast furnace taphole is a weak link in the production process of the blast furnace. The working state of the taphole directly influences the working state of the blast furnace hearth, so the quality of the working condition of the taphole has great influence on the normal production of the iron works. The iron tap hole of the iron-making blast furnace is affected by factors such as construction quality, production operation and material performance after being used for a period of time, and linings with different degrees are peeled off at the iron tap hole part, so that the iron tap hole is in a bell mouth shape, thereby causing the operation environment of the blast furnace to deteriorate in front of the blast furnace, the iron tap hole is difficult to block up the mouth, the amount of stemming is increased, and the normal production and the service life of the blast furnace are directly affected. Therefore, the service life of the taphole of the blast furnace is effectively prolonged by applying the taphole mud sleeve, and the part of the taphole used by the blast furnace, which is matched with the mud gun, is the mud sleeve, so that the taphole needs to be repaired in time when the taphole is damaged in the use process.
At present, the repair of a blast furnace taphole mud sleeve is generally repaired by manpower, 2 workers are required to repair one taphole mud sleeve by 1 iron plate and 1 sledgehammer, the time is 1 hour, the mud jacking is compacted, and the time and the labor are wasted. And the iron notch area has danger factors such as narrow space, high temperature scald, gas poisoning, etc., which increases the difficulty of repair, is easy to have safety accidents after long-time operation, and the repair effect is difficult to ensure.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a repairing device for a blast furnace taphole mud sleeve. The labor intensity of the operation of repairing the blast furnace taphole mud sleeve is reduced, the efficiency is improved, and the personal safety of operating personnel is ensured.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a blast furnace taphole mud sleeve repairing device comprises a blast furnace mud gun, a connecting sleeve and a flat plate; a circular truncated cone-shaped hole and a mud outlet hole are formed in the connecting sleeve, the circular truncated cone-shaped hole is matched with the front end of the blast furnace mud gun, and the circular truncated cone-shaped hole is communicated with the mud outlet hole; the side wall of the connecting sleeve is provided with an L-shaped hanging hole matched with the front end of the blast furnace gun, the L-shaped hanging hole consists of a transverse arched door-shaped hole and a vertical strip-shaped hole, and the arched door-shaped hole is communicated with the strip-shaped hole; more than 4 cylindrical loading and unloading grooves are uniformly distributed on the outer wall of the connecting sleeve; the flat plate is fixedly connected with the end surface of the connecting sleeve, and the front end of the blast furnace gun is inserted into the circular truncated cone-shaped hole of the connecting sleeve and is fixedly connected with the connecting sleeve through the L-shaped hanging hole.
The mud outlet hole is a circular through hole.
The center of the flat plate is provided with a through hole.
Compared with the prior art, the utility model has the beneficial effects that:
the method is convenient to operate, when the method is used, the blast furnace gun is started firstly, the position of the taphole mud sleeve is aligned, the blast furnace gun is operated to be pushed to the taphole mud sleeve repairing surface, and the repair can be completed by grasping the rhythm by pushing forwards. The repair of the taphole mud sleeve can be completed by only 1 person in half an hour by using the utility model, thereby reducing the labor intensity, ensuring the personal safety of operating personnel and greatly improving the operating efficiency.

Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings:
as shown in fig. 1, 2 and 3, a repairing device for a blast furnace taphole mud sleeve comprises a blast furnace mud gun 1, a connecting sleeve 2 and a flat plate 3. The blast furnace mud gun 1 is an existing product, and the blast furnace mud gun 1 is also called a hydraulic mud gun, belongs to necessary stokehold equipment in the smelting industry, and has the function of rapidly and accurately blocking an iron outlet after iron discharge so that a blast furnace can rapidly enter the next cycle of operation.
The connecting sleeve 2 is internally provided with a circular truncated cone-shaped hole 21 and a mud outlet hole 22 in the center, the circular truncated cone-shaped hole 21 is matched with the front end of the blast furnace mud gun 1, the circular truncated cone-shaped hole 21 is communicated with the mud outlet hole 22, and the mud outlet hole 22 is a circular through hole.
The side wall of the connecting sleeve 2 is provided with an L-shaped hanging hole matched with the front end of the blast furnace gun, the L-shaped hanging hole is composed of a transverse arched door-shaped hole 23 and a vertical strip-shaped hole 24, and the arched door-shaped hole 23 is communicated with the strip-shaped hole 24. 4 cylindrical loading and unloading grooves 25 are uniformly distributed on the outer wall of the connecting sleeve, and the loading and unloading grooves 25 are knocked during loading and unloading so as to be convenient for loading and unloading.
The flat plate 3 is a circular iron plate, a through hole 31 is formed in the center of the flat plate 3, and the through hole 31 is circular. The flat plate 3 is vertically welded on the end surface of the mud outlet 22 of the connecting sleeve 2.
