Centralized liquid feeding system for mining area

Abstract

The invention discloses a centralized liquid feeding system for a mining area. A water purification device comprises a flocculation pretreatment device, a filtering device, a water softening device, a pH adjustment device and a water storage device; a liquid preparation device comprises a liquid preparation box, a mixer, a concentration sensor, a second electric control valve, a water gauge, a high-pressure pump, a gear oil pump and a frequency converter; a liquid feeding device comprises a plurality of emulsified liquid feeding components and working face liquid returning components. The centralized liquid feeding system for the mining area realizes automatic compounding of emulsified oil and clear water, the liquid feeding quality of an emulsified liquid is improved, the liquid compounding efficiency is improved, lots of power resources are saved, the breakdown frequency of an emulsified liquid pump is reduced, the maintenance cost is lowered, and the usability of the emulsified liquid pump and the operating steadiness of a hydraulic system are guaranteed.

Description

technical field [0001] The invention relates to the field of coal mines, in particular to a centralized liquid supply system for a mining area. 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. The traditional emulsion configuration is mostly done manually. This method is labor-intensive, and it cannot guarantee that the concentration of the emulsion configured each time can meet the requirements of use, and the efficiency and quality of the liquid preparation need to be improved; in addition, due to the The configuration has certain requirements on water quality. If there are a large amount of turbidity, suspended solids, particle size, acid-base and other harmful substances i...

The traditional emulsion configuration is mostly done manually. This method is labor-intensive, and it cannot guarantee that the concentration of the emulsion configured each time can meet the requirements of use, and the efficiency and quality of the liquid preparation need to be improved; in addition, due to the The configuration has certain requirements on water quality. If there are a large amount of turbidity, suspended solids, particle size, acid-base and other harmful substances in the actual mine water, it will wear and corrode the underground hydraulic equipment and cause the safety of the hydraulic support in use. Hidden dangers; moreover, the emulsion pump station mostly adopts decentralized liquid supply, and the emulsion pump in this way runs at high speed for a long time, consuming a lot of power resources; the pressure generated during the process of returning to the emulsion tank through the unloading valve can be transformed into A large amount of heat energy ages the sealing parts in the emulsion pump, seriously affects the performance of the emulsion pump, and reduces the stability of the hydraulic system
