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.

Embodiment 1

[0047] see Figure 1-5 , a flushing mud circulation and slag discharge system for a shaft boring machine, comprising a slurry inlet pipeline, a slurry discharge pipeline, a backwash pipeline and a mud treatment device, one end of the slurry inlet pipeline is connected to the mud treatment device, and the other end is arranged on the In the excavation chamber of the roadheader, it is used to transport the slurry treated by the mud treatment device to the excavation chamber. The slurry in the excavation bin is transported to the mud treatment device, and the circulation of the slurry between the excavation bin and the mud treatment device is realized through the cooperation of the slurry inlet pipeline and the slurry discharge pipeline;

[0048] The backwash pipeline includes a backwash slurry inlet branch and a backwash slurry discharge branch, and the backwash slurry inlet branch is connected to the slurry outlet 33 in the excavation bin and the slurry inlet pipeline, The slu...

Abstract

The invention provides a scouring mud circulation slag discharge system for a shaft boring machine, comprising a slurry inlet pipeline, a slurry discharge pipeline, a backwash pipeline and a mud treatment device, one end of the slurry inlet pipeline is connected to the mud treatment device, and the other is One end is set in the excavation bin of the roadheader to transport the slurry treated by the mud treatment device to the excavation bin. The slurry pipeline transports the slurry in the excavation chamber to the mud treatment device; the backwash pipeline includes a backwash slurry inlet branch and a backwash slurry discharge branch, and the backwash slurry inlet branch is connected to the slurry inlet pipeline and the slurry discharge pipeline are located at the slurry discharge port in the excavation bin, one end of the backwash slurry discharge branch is connected to the slurry discharge pipeline, and the other end is arranged in the excavation bin. By scouring the specific position of the cutter head, it is possible to prevent undesirable phenomena such as slag sticking to the cutter head and mud cake on the cutter head during the excavation process.

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...
