Mining explosion-proof type thin oil lubrication station

Abstract

The invention provides a mining explosion-proof type thin oil lubrication station. The station comprises an oil tank, an oil outlet pipeline, an oil return pipeline, an oil pump, a one-way valve, a safety valve, a double-barrel filter, a cooler and an electric control box, wherein the oil return position of the oil tank is provided with a magnetic filtering device, the oil outlet pipeline comprises a first pipeline, a second pipeline and a third pipeline, wherein one end of the first pipeline and one end of the second pipeline communicate with the oil tank, the other end of the first pipelineand the other end of the second pipeline communicate with the input end of the double-barrel filter, one end of the third pipeline communicates with the output end of the double-barrel filter, the other end of the third pipeline is branched into a fourth pipeline with a first oil outlet and a fifth pipeline with a second oil outlet, one end of the oil return pipeline communicates with the magneticfiltering device, the other end of the oil return pipeline is branched into a sixth pipeline with a first oil return port and a seventh pipeline with a second oil return port, the cooler is an air cooler, and a shell of the electric control box is a metal closed explosion-proof type panel.

Description

technical field [0001] The invention relates to the technical field of lubricating equipment, in particular to an explosion-proof thin oil lubricating station for mines. Background technique [0002] In the prior art, the cooler in the thin oil station usually adopts a water-cooled cooler, such as a shell-and-tube oil cooler. The cold water actually used for heat exchange in production is mostly sewage or clear water with high salinity, and this kind of water is easy to form scale on the inner wall of the cooler, which greatly reduces the thermal efficiency. In addition, the shell and tube oil cooler cannot be directly descaled , if it needs to be disassembled for cleaning, special equipment must be used to assemble it after cleaning. If there is no special assembly equipment on site, production can only be stopped and replaced as a whole. Frequent replacement will greatly increase the operating cost; on the other hand, underground coal mines The space is limited, and the m...

The cold water actually used for heat exchange in production is mostly sewage or clear water with high salinity, and this kind of water is easy to form scale on the inner wall of the cooler, which greatly reduces the thermal efficiency. In addition, the shell and tube oil cooler cannot be directly descaled , if it needs to be disassembled for cleaning, special equipment must be used to assemble it after cleaning. If there is no special assembly equipment on site, production can only be stopped and replaced as a whole. Frequent replacement will greatly increase the operating cost; on the other hand, underground coal mines The space is limited, and the mine explosion-proof thin oil lubrication station also needs to consider the space occupied by the actual production
