Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
as shown in fig. 1, the cooling system of a blast furnace gearbox of the present invention includes a main cooling system and a backup cooling system; the main cooling system is formed by sequentially connecting a water cooling station water pump 1, a gear box cooling pipeline 2 and a receiving tank 3; the standby cooling system is formed by sequentially connecting a lifting pump station water pump 4, a water cooling station plate heat exchanger 5 and a water tank 6; the outlet pipeline of the water pump 4 of the lifting pump station is connected with the outlet pipeline of the water pump 1 of the water cooling station through a connecting pipeline, and a valve 7 is arranged on the connecting pipeline.
And an automatic drain valve 8 is arranged at the bottom of the receiving tank 3.
The valve 7 is an electric gate valve.
The cooling system of the blast furnace gear box also comprises a control system; and the electric gate valve is interlocked with the water cooling station water pump 1 and the lifting pump station water pump 4 through a control system.
The receiving tank 3 is provided with a liquid level meter, and the liquid level meter and the automatic blowdown valve 8 are controlled in an interlocking mode through a control system.
The principle of a cooling system of a blast furnace gear box is as follows: the surplus capacity of a secondary cooling water source of a plate type heat exchanger of a water cooling station at the top of the blast furnace is utilized as a standby cooling water source of the gear box when a water pump of the water cooling station fails.
The utility model relates to a cooling system of blast furnace gear box's implementation process as follows:
firstly, determining the position of the connection between the outlet pipeline of the water pump of the water cooling station and the outlet pipeline of the water pump of the lifting pump station.
And a connecting pipeline and a valve are installed at the joint, and the valve adopts an electric control gate valve and is interlocked and controlled with a water pump of a lifting pump station and a water pump of a water cooling station.
When the system normally operates, the pressure of an inlet of the plate type heat exchanger of the water cooling station is about 0.45MPa, the pressure of a circulating pump of the water cooling station is about 0.3MPa, when a water pump of the water cooling station stops pumping and water is cut off, the system automatically switches to supply water for a cooling pipeline of a gear box by the plate type heat exchanger of the water cooling station, after cooled return water enters a receiving tank through a return water tank, the liquid level of the receiving tank rises, and the liquid level is controlled by an automatic drain valve at the bottom of the receiving tank.
And after the water pump of the water cooling station is maintained and treated, the system is switched to the original operation mode again.
The above description is only the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the concept of the present invention within the technical scope disclosed in the present invention.
