Mud flushing circulation taphole system for shaft heading machine

Abstract

The invention provides a mud flushing circulation taphole system for a shaft heading machine. The mud flushing circulation taphole system comprises a mud inlet pipeline, a mud discharging pipeline, ananti-flushing pipeline and a mud processing device, wherein one end of the mud inlet pipeline is connected with the mud processing device, and the other end of the mud inlet pipeline is arranged in an excavating bin of a heading machine, so that the mud processed by the mud processing device is transported to the excavating bin; one end of the mud discharging pipeline is arranged in the excavating bin, and the other end of the mud discharging pipeline is connected with the mud processing device; mud in the excavating bin is transported to the mud processing device by the mud discharging pipeline; the anti-flushing pipeline comprises an anti-flushing mud inlet branch and an anti-flushing mud discharging branch; the anti-flushing mud inlet branch is connected with mud discharging openings in the excavating bin, of the mud inlet pipeline and the mud discharging pipeline; and one end of the anti-flushing mud discharging branch is connected with the mud discharging branch, and the otherendof the anti-flushing mud discharging branch is arranged in the excavating bin. According to the mud flushing circulation taphole system disclosed by the invention, flushing is performed on specific positions of a cutter head, so that the generation of bad phenomena of pasting the cutter head with muck, forming a mud cake on the cutter head and the like in the heading process can be avoided.

Description

technical field [0001] The invention relates to the technical field of roadheaders, in particular to a flushing mud circulation and slag discharge system for a shaft roadheader. Background technique [0002] With the development of today's science and technology, people's development and utilization of underground space resources are becoming more and more extensive. In underground engineering, roadheaders are favored by various construction units because of their high construction efficiency, high safety and comfortable working environment. At present, shafts of different sizes need to be excavated in many fields such as underground engineering, mineral mining, municipal water conservancy, civil air defense and military affairs, so the development of shaft boring machine technology has attracted widespread attention. Shaft excavation is different from conventional horizontal excavation. It is impossible to use screw conveyors combined with belt conveyors for continuous sla...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, although there is a slag discharge method that uses mud to carry the slag, there is no flushing device for the cutter head and the slurry discharge port, so it is easy to cause mud cake and paste on the cutter head during the excavation process, and the slurry discharge The mouth is also easily blocked by slag, which affects the construction efficiency and reliability

Once this happens, construction personnel need to go down the well to dredge, which increases the labor intensity of construction personnel.
