Novel bentonite stirring system of full-section tunnel boring machine

Abstract

The invention provides a novel bentonite stirring system of a full-section tunnel boring machine. The novel bentonite stirring system comprises a bentonite pump, a bentonite box, a first stirring pipe, a second stirring pipe, a water inlet pipe, an air inlet pipe and a spraying pipe, wherein the first stirring pipe and the second stirring pipe are arranged in the bentonite box; the bentonite pumpis communicated with the first stirring pipe and the second stirring pipe through pipelines; one-way valves are arranged at the starting end of the first stirring pipe and the starting end of the second stirring pipe at the positions extending out of the bentonite box; the spraying pipe is mounted above the bentonite box; the water inlet pipe is communicated with the spraying pipe, the first stirring pipe and the second stirring pipe; the upper end of the bentonite box is communicated with an exhausting pipe; the bottom end of the bentonite box is communicated with a discharging pipe; and a plurality of pipe connectors are arranged on the first stirring pipe and the second stirring pipe. According to the novel bentonite stirring system of the full-section tunnel boring machine, bentonite stirring of the full-section tunnel boring machine is more economical and effective; an original mechanical stirring manner can be completely replaced, so that the cost is reduced, resources are saved,manpower is saved and the stirring effect is improved.

Description

technical field [0001] The invention belongs to the technical field of roadheaders, and in particular relates to a novel bentonite mixing system of a full-section tunnel boring machine. Background technique [0002] At present, the bentonite of the full-section tunnel boring machine is mechanically stirred, which is uneven and prone to dead angles. Manual control of the stirring is required, and the mixing effect is not good for large-capacity bentonite boxes. Contents of the invention [0003] In view of this, the present invention aims to provide a novel bentonite mixing system for a full-face tunnel boring machine, which can solve the problems in the prior art. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005] A new bentonite mixing system for a full-face tunnel boring machine, including a bentonite pump, a bentonite box, a first stirring pipe, a second stirring pipe, a water inlet pipe, an air ...
