Furnace top hydraulic water pumping device

Abstract

The invention discloses a furnace top hydraulic water pumping device. The furnace top hydraulic water pumping device comprises a spray pipe, wherein the spray pipe is arranged in an outer sleeve; one end of the outer sleeve is connected with a short pipe through a flange; the short pipe is connected with a shaft seal; one end of the spray pipe is connected with a spray head, and the other end of the spray pipe is communicated with the cavity of the short pipe; an ejector rod is arranged in the spray pipe; one end of the ejector rod is connected with an ejection head, and the other end of the ejector rod penetrates through the shaft seal to be connected with a driving device through a coupling; the ejection head is connected with the spray head in a matching manner; and the spray head is fixedly arranged at one end of the spray pipe through the outer sleeve. According to the furnace top hydraulic water pumping device, the tests show that the cooling area of the furnace top is increased from the 50 percent of the original water column cooling to 100 percent, meanwhile, the water consumption required for atomization cooling is also greatly reduced, and the amount of saved water is about 50 percent of the prior art; and an electro-hydraulic driver or a linear reciprocating motor is adopted as a driving device, so that the work is reliable and the efficiency is greatly improved compared with the prior art, and remote control can be further realized and timed control can be performed after the remote controller is additionally arranged.

Description

technical field [0001] The invention relates to a furnace top cooling device on a steelmaking or smelting furnace, in particular to a furnace top hydraulic water pumping device. Background technique [0002] Steelmaking (iron) furnace is the most important smelting equipment in iron and steel enterprises. Its working temperature is quite high, and the maximum internal temperature exceeds 1540°C. In order to keep warm, the shell of the furnace is covered with heat-resistant materials. temperature, to prolong its service life, it is very necessary to install a top cooling device. [0003] The existing furnace roof cooling device is relatively simple. It directly leads the water pipe to the furnace roof for water column cooling. The water outlet of the water pipe is placed in the middle of the furnace roof, and a water valve is connected to the water pipe to open and close and control the cooling water. After the water flow falls, it flows down the furnace wall and takes away ...

Problems solved by technology

However, the new effect of this kind of furnace roof cooling device is not good. The water flows directly in a small area of ​​the furnace roof, and then flows along the furnace wall. The range is small and the cooling of the entire furnace wall is uneven, and even local deformation of the furnace wall may be caused in severe cases; in order to improve the cooling effect, the most common way is to increase the flow of cooling water, but this method wastes a lot of water resources and is actually harmful to The cooling boost doesn't help much
