[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0024] The blast hole drill lubricating oil mist collector for blast furnace opening is aimed at reducing environmental pollution, and the condensed lubricating oil is collected and reused, specifically as follows:

[0025] Please refer to Figure 1 , the blast hole drill lubricating oil mist collector for blast furnace opening, comprising a collecting pipe body 1 installed at the bottom side of the blast hole drill 7, an air inlet 2 at the tail end of the collecting pipe body 1 is connected with the lubricating oil mist discharge port on the blast hole drill 7, responsible for introducing the generated oil mist into the collecting pipe body 1, the oil mist is separated after entering the collecting pipe body 1, the oil therein is precipitated, and the gas rises;

[0026] The collecting pipe body 1 is a seamless steel pipe with a length of 1100mm, an outer diameter of 60mm, and a wall thickness of 3mm. The seamless steel pipe can quickly dissipate heat, which helps the quick condensation and separation of oil mist.

[0027] An exhaust nozzle 4 is threadedly installed in the exhaust port formed on the upper side of the front part of the collecting pipe body 1, and a filter layer 3 is arranged on the exhaust nozzle 4. The exhaust nozzle 4 and the filter layer 4 cooperate to discharge clean air remaining after filtration and condensation, and preliminarily filter out large-particle impurities in the oil mist, so as to avoid pollution to the external environment.

[0028] An oil drain valve 5 is also installed at the bottom-side outlet of the front end of the collecting pipe body 1. The oil drain valve 5 is preferably a ball valve and is threadedly installed at the bottom-side outlet of the front end of the collecting pipe body 1. The oil drain valve 5 is opened at regular intervals to discharge oil into a prepared container for safe or recycling treatment.

[0029] The arrangement of the oil drain valve 5 at the front end can provide sufficient cooling time and space for the oil mist, so that the discharged oil mist is condensed lubricating oil.

[0030] Please refer to Figure 1 , the blast furnace taphole drill lubricating oil mist collector. A pipe clamp 6 is welded and fixed at the bottom side of the blast furnace drill 7. The pipe clamp 6 is composed of a top clamp plate fixed at the bottom side of the blast furnace drill 7 and a bottom clamp plate located below the top clamp plate. The two are connected by bolts. The bolts are used to control the size of the pipe clamp 6. After the collecting pipe body 1 is placed between the top clamp plate and the bottom clamp plate, the collecting pipe body 1 is fixed by tightening the bolts on the pipe clamp 6.

[0031] Please refer to Figure 1 , the blast furnace taphole drill lubricating oil mist collector. The filter layer 3 is detachably replaced in the exhaust nozzle 4, and the exhaust nozzle 4 is threadedly connected with the exhaust port formed on the upper side of the collecting pipe body 1.

[0032] Please refer to Figure 1 , the blast furnace taphole drill lubricating oil mist collector. The air inlet 2 at the tail end of the collecting end is connected with the lubricating oil mist discharge port on the blast furnace drill 7 through a conveying pipe 8, and the conveying pipe 8 is threadedly connected with the air inlet 2 at the tail end of the collecting end.

[0033] The conveying pipe is preferably a DN13 heat-resistant rubber pipe with a length of 800mm.

[0034] Before the improvement, it is difficult to collect oil mist. After the high-speed operation of the oil mist lubricated mechanical parts, the remaining lubricating oil mist is discharged from the tail of the blast furnace drill 7. These oil mists not only pollute the working environment, but also may pose a potential threat to the equipment itself and the health of the operators. After the installation and use of the taphole drill lubricating oil mist collector, the use effect is good, and the expected target requirement is achieved.

[0035] The specific structure and working principle of the non-disclosed part in the utility model are not described again.

[0036] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
