Automatic slurry jetting machine and slurry jetting method

Abstract

The invention discloses an automatic slurry jetting machine and a slurry jetting method. The automatic slurry jetting machine comprises a car body, a central control system, a slurry jetting system, adynamic system and a power supply; the central control system comprises a PLC controller and a control panel, the control panel is used for inputting control parameters of the automatic slurry jetting machine; the slurry jetting system comprises a slurry storage tank, a slurry jetting pressure pump, a slurry jetting pressure pump driving motor and a slurry jetting device; a pumping inlet end of the slurry jetting pressure pump is connected to the slurry storage tank, a pumping outlet end of the slurry jetting pressure pump is connected to the slurry jetting device; the slurry jetting pressurepump is used for pumping slurry in the slurry storage tank into the slurry jetting device; the slurry jetting device jets the slurry out, the dynamic system is used for driving the car body; the power supply is used for supplying power for the central control system, the slurry jetting system and the dynamic system. By adopting the automatic slurry jetting machine and the slurry jetting method, moving parameters and slurry jetting control parameters of the automatic slurry jetting machine are only needed to be entered, automatic control of slurry jetting process can be realized, a worker to manipulate in real time is not needed, therefore the labor intensity of labor is greatly reduced.

Description

Technical field [0001] The invention relates to the technical field of mine safety and fire prevention, in particular to an automatic shotcrete machine and a shotcrete method. Background technique [0002] Mine fire is one of the major disasters in coal mines. At present, one of the important measures to prevent coal spontaneous combustion is to spray slurry and inhibitor to prevent spontaneous combustion of coal. Spraying slurry and inhibitor can prevent spontaneous combustion of coal from three aspects: one is to block air leakage The channel reduces air leakage and reduces the contact between coal and air; the second is to adhere to the surface of the coal body to isolate the coal from oxygen and prevent the oxidation of the coal; the third is to reduce the temperature of the coal body to prevent the coal from reaching the ignition point. Therefore, improving the spraying equipment of the inhibitor slurry and improving the spraying efficiency are of great significance for prev...

AI Technical Summary

Problems solved by technology

For example, a mine shotcrete machine in the prior art is composed of a lifting unit and a rotating unit. The lifting unit is composed of upper and lower brackets. The mechanical structure of the system is complicated, the spray gun cannot cover the roadway at 360°, and there is no motorized device. , It is difficult to move, and the shotcrete machine cannot realize automatic control, and real-time control is still required by the operator

Another example is a mobile continuous mixing and spraying system for mining in the prior art, which is composed of a shuttle car system, a mixing system and a spraying system; although the system can be moved, it cannot fully control the entire spraying process. The spray gun still needs to be operated manually, and the demand for labor intensity of workers is still relatively high
