Automatic switching equipment for filling pipeline

Abstract

The invention discloses automatic switching equipment for a filling pipeline. During filling, a first connection pipe orifice is connected with a filling pump; a second connection pipe orifice is connected with a main pipe; a third connection pipe orifice is connected with an assistant pipe; at the moment, the pipe orifice I of a first connection pipeline is hermetically communicated with the first connection pipe orifice; the pipe orifice II of the first connection pipeline is hermetically communicated with the second connection pipe orifice; the main pipe is taken as a filling pipeline; a signal is immediately transmitted to a controller when a pressure detection component positioned inside the first connection pipe orifice detects that the filling pressure of the main pipe serving as the filling pipeline exceeds a pressure threshold value; the controller is used for controlling a direct moving component to act in order to drive a sliding body to move after receiving an accident signal indicating that the main pipe is blocked, so that the pipe orifice I of a second connection pipeline is hermetically communicated with the first connection pipe orifice, and the pipe orifice II of the second connection pipeline is hermetically communicated with the third connection pipe orifice; at the moment, the assistant pipe is taken as the filling pipeline in order to continually finish filling operation. By adopting the automatic switching equipment, automatic switching between the main pipe and the assistant pipe can be realized rapidly, and the filling operation is not influenced.

Description

Technical field [0001] The invention relates to an automatic switching device for filling pipelines. Background technique [0002] In the process of mine paste filling, in order to prevent the pipeline from being blocked and stop filling, which affects the filling efficiency, two filling pipelines are generally used, the main pipe and the auxiliary pipe. Under normal circumstances, the main pipe is used as the filling pipe and the auxiliary pipe is used as the spare pipe. road. When a pipe blockage accident occurs in the supervisor, it is necessary to switch to the auxiliary pipe in time to avoid affecting the normal filling operation. Most of the filling pumps in the prior art are flanged to the main pipe or the auxiliary pipe through a connecting pipe. When the main pipe is blocked, the disassembly and assembly of the flange is troublesome, time-consuming and laborious, which makes it difficult for the staff to change the pipe and the filling operation. Aborted. Summary of t...

Problems solved by technology

Most of the filling pumps in the prior art are flange-connected with the main pipe or the auxiliary pipe through the connecting pipe. When the main pipe is blocked, the disassembly and assembly of the flange is troublesome, time-consuming and labor-intensive, which makes it difficult for the staff to change the pipe and the filling operation is difficult. suspend
