Embodiment 1

[0039] Such as figure 1 , figure 2 , image 3 As shown, the water cleaning and recycling system of a blast furnace pit area in this embodiment mainly includes a sewage pool 1, a clean water pool 2, a water collection pool 3, a drainage pump 4 and a sewage drainage ditch 5, and their mutual combination forms a closed cycle The water cleaning system cleans the ground dust particles in the mine tank area to ensure the bottom surface is clean.

[0040] from figure 1 The ore trough area observed from the top view angle, the ore trough is arranged along the left and right directions, with an unloading car on it, and a conveying device is installed at the left end of the ore trough to send the raw ore in the ore trough to the blast furnace. The conveying device has a transmission chamber , to control the operation of the conveying device; there are mineral powder bins and coke powder bins on both sides of the conveying device to supply mineral powder and coke powder for the ore t...

Embodiment 2

[0050] The water cleaning and recycling system in the blast furnace mine tank area of ​​this embodiment is optimized based on the layout characteristics of the mine tank area and the characteristics of the materials to be cleaned on the basis of embodiment 1, so as to achieve better cleaning effect. Because most of the mine tank blanking is concentrated on both sides of the mine tank, there is a certain distance from the sewage ditch 5, and the mineral material is heavy and difficult to dissolve in water. Therefore, the cleaning water pressure is very good, and high-power drainage is required. The pump 4 undoubtedly increases the burden of the drain pump 4, even so, the effect is also unsatisfactory.

[0051] For this, combine figure 1 , Figure 4 with Figure 5 As shown, in this embodiment, on the ground of the ore trough area, the height of the extension of the sewage ditch 5 on both sides of the upper and lower sides gradually decreases with the ore trough as the center, ...

Embodiment 3

[0056] The water cleaning and recycling system in the blast furnace pit area of ​​this embodiment is further optimized and designed on the basis of Embodiment 2 to treat suspended dust in the air.

[0057] Due to the unavoidable generation of dust during the operation of the mine tank area, the dust concentration in the air is high, and the operating environment is relatively harsh; even if the ground has been cleaned, as the dust in the air falls, the ground dust will continue to accumulate. It also affects the cleaning effect. Therefore, the present embodiment is provided with a plurality of spray nozzles 9 at intervals along one side of the drain ditch 5 in the three cleaning areas. Spraying water mist in the air can make the dust in the air settle quickly, which is conducive to improving the working environment of the mine tank, improving the air quality, and reducing the continuous dust falling to the ground. The purpose that the spray nozzle 9 is arranged along the drai...

Abstract

The invention discloses a cleaning and recycling system of blast furnace ore tank area water and a using method of the cleaning and recycling system and belongs to the technical field of blast furnaceore tank dust removing. The system comprises a sewage pond, a clean water pond and a water discharging pump; the two sides of an ore tank are each provided with a sewage discharging trench which is connected to a sewage inlet of the sewage pond; the sewage pond and the clean water pond are adjacently arranged, and are communicated through a clean water inlet formed in the upper side; a water inlet of the water discharging pump is connected into the clean water pond; and a water outlet of the water discharging pump is connected to cleaning water spraying heads of areas on the two sides of theore tank through water discharging pipes. According to the cleaning and recycling system of the blast furnace ore tank area water and the using method of the cleaning and recycling system, by means ofthe relatively closed type structural design, circulating water is utilized for cleaning the ore tank areas, flying dust and water pollution can be effectively avoided, and ore charge obtained through cleaning can be recycled.

Description

technical field [0001] The invention belongs to the technical field of dedusting in a blast furnace mine tank, and more specifically relates to a water cleaning and recycling system in a blast furnace mine tank area and a method for using the same. Background technique [0002] The blast furnace ore tank is used to store the raw ore fuel required for blast furnace production. It transports the raw materials such as sinter, pellets and lump ore required for blast furnace production through the feeding system to the blast furnace storage tank through a belt conveyor. The mobile unloading vehicle on the upper part of the trough makes bins to the ore trough, and the lower part of the ore trough has material conveying equipment, including vibrating screens for screening raw materials and fuels, feeders for transfer and weighing, and belts for raw and fuel transportation Conveyor etc. With this kind of structure, a large amount of raw fuel particles and dust will be generated in ...
