Problems solved by technology

However, there are also some problems in screening lump ore powder in this way, because the feeder is generally used to transport the lump ore between the vibrating screen and the silo, and there is no control valve between the feeder and the mouth of the silo. After the feeder stops running, part of the lump ore will fall to the feeder by gravity. Under the aftershock of the feeder, part of the lump ore will fall to the vibrating screen bed. At this time, the vibrating screen has stopped running, resulting in every When the vibrating screen is running for the first time, there are residual materials on the sieve bed, which increases the difficulty of sieving powder on the sieve bed
In addition, in the prior art, some deflectors arranged inclinedly are added in front of the vibrating screen for flow diversion, but when the vibrating screen stops running, the lump ore on the deflectors arranged obliquely will also fall under the action of gravity to the vibrating screen, which will also increase the difficulty of sieving the powder in the sieve bed

Embodiment 1

[0084] This embodiment provides a screening system 10 for wet powder-containing lump ore. The screening system 10 includes a feeder 11 , a vibrating screen 12 , a diverting mechanism 13 , a material guide trough 14 and a receiving hopper 15 . Wherein, the support plate 1321 of the flow diversion mechanism 13 is arranged horizontally, the height difference between the end of the support plate 1321 and the input end 121 of the vibrating screen 12 is 180 mm, and the end of the feed channel 14 close to the output end 122 of the vibrating screen 12 is connected to the vibrating screen 12 The height difference of the output end 122 is 12mm, the horizontal distance between the first dead center and the output end 122 of the vibrating screen 12 is 20mm, the inclination angle of the vibrating screen 12 is 26 °, the top of the receiving hopper 15 and the output end 122 of the vibrating screen 12 The height difference is 500mm, and the horizontal distance between the edge of the output en...

Embodiment 2

[0087] This embodiment provides a screening system 10 for wet powder-containing lump ore. The screening system 10 includes a feeder 11 , a vibrating screen 12 , a diverting mechanism 13 , a material guide trough 14 and a receiving hopper 15 . Wherein, the support plate 1321 of the flow diversion mechanism 13 is arranged horizontally, the height difference between the end of the support plate 1321 and the input end 121 of the vibrating screen 12 is 180 mm, and the end of the feed channel 14 close to the output end 122 of the vibrating screen 12 is connected to the vibrating screen 12 The height difference of the output end 122 is 10mm, the horizontal distance between the first dead center and the output end 122 of the vibrating screen 12 is 15mm, the inclination angle of the vibrating screen 12 is 20°, the top of the receiving hopper 15 and the output end 122 of the vibrating screen 12 The height difference is 500mm, and the horizontal distance between the edge of the output end...

Embodiment 3

[0090] This embodiment provides a screening system 10 and a screening method for wet powder-containing lump ore. The screening system 10 is basically the same as the screening system 10 in Embodiment 1, except that the first dead point is the same as that of the vibrating screen. The horizontal distance of the output end 122 of 12 is 25mm.

Abstract

The invention discloses a screening system and screening method for wet powder-containing lump ore, and belongs to the field of lump ore screening. The screening system for wet powder-containing lumpore comprises a feeder, a vibrating screen and a flow dividing mechanism, wherein the input end of the vibrating screen is arranged below a discharge port of the feeder, the flow dividing mechanism comprises an elastic component and a flow dividing component, the elastic component is installed at the input end of the vibrating screen, and the flow dividing component is supported between the inputend of the vibrating screen and a discharge port of the feeder through the elastic component so that lump ore output from the feeder can enter the vibrating screen from the flow dividing component when the vibrating screen is started. According to the screening system and screening method, lump ore can be prevented from accumulating on the vibrating screen, and the powder screening difficulty of the vibrating screen is reduced.

Description

technical field [0001] The application relates to the field of lump ore screening, in particular to a screening system and screening method for wet powder-containing lump ore. Background technique [0002] During the rainy season, the lump ore contains high powder and is humid. Vibrating screens are usually used to screen the lump ore in the blast furnace field. The wet powder-containing lump ore is easily bonded to the screen, resulting in the powder cannot be effectively screened. In the prior art, the powder of lump ore is screened out by increasing the screen area or changing the inclination angle of the screen. However, there are also some problems in screening lump ore powder in this way, because the feeder is generally used to transport the lump ore between the vibrating screen and the silo, and there is no control valve between the feeder and the mouth of the silo. After the feeder stops running, part of the lump ore will fall to the feeder by gravity. Under the aft...
