Automatic production device for foaming agent of tunnel boring machine

Abstract

The invention relates to an automatic production device for a foaming agent of a tunnel boring machine. The automatic production device comprises a bracket, a kettle, a feed port, a discharge port, a stirrer, a temperature detector, a split packing machine and a central control console, wherein production raw materials of the foaming agent of the tunnel boring machine are directly fed into the kettle through the feed port, produced foaming agent of the tunnel boring machine is conveyed to the split packing machine through the discharge port, the kettle is supported by the bracket for stabilization, the stirrer is used for uniformly stirring the raw materials in the kettle, the temperature detector is located on the inner wall of the kettle and used for monitoring the temperature in the kettle in real time, and the stirrer, the temperature detector and the split packing machine are all connected with the central control console, so that working parameters are controlled. The automatic production device for the foaming agent of the tunnel boring machine is scientific and reasonable in structure and high in safety, the added temperature detector can detect the temperature of the materials in the kettle in real time, heat accumulation caused by over-stirring and a liquid mixed reaction is prevented, the safety of foaming agent production is improved effectively, an artificial transfer process for the foaming agent is omitted due to connection of the split packing machine and the kettle, and the production efficiency is increased substantially.

Description

technical field [0001] The invention relates to the field of foam agent production equipment, in particular to an automatic production device for shield machine foam agent used in shield tunneling operations. Background technique [0002] The shield machine works in the soil with high friction. When excavating in the earth pressure balance mode, the cutter is prone to wear, the cutter head and the screw conveyor are worn, which increases the torque of the cutter head, and then the machine consumes too much energy and heats up. In addition, due to changes in the stratum, it is usually difficult for the untreated soil to enter the soil bin to obtain the expected fluidity. At this time, problems such as "mud cake" and "blockage" are prone to occur in the soil bin. When the excavation surface is too high, the water pressure at the excavation surface will cause a large amount of groundwater loss at the exit of the screw conveyor of the shield machine. In severe cases, foaming age...
