Emulsified liquid supply device

Abstract

The invention discloses an emulsified liquid supply device. A liquid level sensor, a liquid temperature sensor and a stirring component are arranged in an emulsified liquid box; the emulsified liquid box, a liquid imbibition filter, an energy accumulator group and a working face bracket are sequentially communicated through a liquid delivery pipeline; a mechanical unloading valve and a pressure sensor are arranged on the liquid delivery pipeline; the mechanical unloading valve is further connected with a liquid return pipeline; a liquid outlet of the liquid return pipeline stretches into the emulsified liquid box; a buffer is arranged on the liquid return pipeline; a liquid return filter communicates with the working face bracket and the emulsified liquid box through a pipeline; a thermal insulation sleeve is connected onto the periphery of the emulsified liquid box in a sleeving manner and forms a backflow passage with the emulsified liquid box; and a cold and hot water supply device communicates with a water flow passage through a pipeline. The emulsified liquid supply device, disclosed by the invention, saves plenty of electric power resource and reduces the failure rate of an emulsified liquid pump and the overhaul cost; and stability of the emulsified liquid temperature ensures the usability of the emulsified liquid pump and the working stability of a hydraulic system.

Description

technical field [0001] The invention relates to the field of coal mines, in particular to an emulsion liquid supply device. Background technique [0002] The mining emulsion pumping station is one of the key equipments in the modern high-yield and efficient fully mechanized mining face of the coal mine. In order to ensure the safe and reliable operation of the fully mechanized mining face, it is necessary to transport the emulsion to the mining emulsion pumping station. Traditional emulsion pumping stations mostly use decentralized liquid supply. In this way, the emulsion pump runs at high speed for a long time, which consumes a lot of power resources; the pressure generated during the process of returning to the emulsion tank through the unloading valve can convert a large amount of heat energy. The sealing parts in the emulsion pump are aged, which seriously affects the performance of the emulsion pump and reduces the stability of the hydraulic system. Contents of the ...
