Description

Cooling water system of emulsion pump station

Technical Field

The utility model relates to an emulsion pump station, in particular to a cooling water system of the emulsion pump station.

Background

The emulsion pump station is important equipment in coal mining, and it provides power liquid for strutting equipment in the pit, includes three emulsion pumps and an antifreeze liquid pump at present in the pump station, and the long-time work of emulsion pump leads to the lubricating oil temperature of gear box and crankcase to rise easily, and lubricated effect reduces, needs the cooling water to cool down it. The existing cooling water system of the emulsion pump station mainly has the following defects: (1) with the intelligent development of underground equipment, the emulsion pump station is remotely operated, but a cooling water system still needs to be switched on and off in a pump room, so that the equipment is inconvenient; (2) the condition that cooling water is forgotten to be switched on and off is easily caused by manual switching; (3) the direct discharge of cooling water results in serious waste of water resources, and the water consumption is about 20 tons per week; (4) once the water supply is cut off, the water supply company cannot use the cooling water.

In order to solve the above problems, people are always seeking an ideal technical solution.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art, and provides the cooling water system of the emulsion pump station, which has the advantages of scientific design, convenient control, water resource saving and no influence of water cut-off.

In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides an emulsion pump station cooling water system, includes four cooling water collecting boxes, circulating water pump, inlet manifold, return water house steward and electric cabinet, the inlet manifold intercommunication circulating water pump's delivery port, inlet manifold passes through inlet branch pipe and every the water inlet intercommunication of cooling water collecting box, return water house steward passes through return water branch pipe and every the delivery port intercommunication of cooling water collecting box, return water house steward intercommunication circulating water pump's water inlet, every all be provided with the solenoid valve on the inlet branch pipe, the electric cabinet control is four the switch of solenoid valve.

Based on the above, the return water main pipe is provided with the cooling water settling tank.

Based on the above, the water return main pipe is a galvanized pipe.

Based on the above, the water inlet main pipe is a hot melting pipe.

Compared with the prior art, the utility model has substantial characteristics and progress, and particularly, the utility model utilizes four cooling water collecting boxes to respectively collect cooling water for cooling three emulsion pumps and one antifreezing liquid pump, utilizes the circulating water pump, the water inlet header pipe, the water return header pipe, the water inlet branch pipe and the water return branch pipe to form a circulating loop, thereby saving water resources and getting rid of the limitation of tap water cut-off, realizes the remote control of the cooling water by controlling the switch through the four electromagnetic valves by the electric control cabinet, and has the advantages of scientific design, convenient control, water resource saving and no influence of water cut-off.

Furthermore, the cooling water sedimentation tank is arranged, so that the recovered cooling water can be sedimentated, and the risk of blockage of the circulating pipeline is reduced.
