Abstract
The invention discloses a vibrating screen below the groove, belonging to the screening technology, comprising a screen box. An air induced duct which is communicated with an air duct above the screen plate inside the screen box is arranged above the feed inlet of the screen box. The other end of the air induced duct is connected with the air outlet of a fan. The air inlet of the fan is connected with the exhaust gas outlet of a wind iron furnace. Radial holes opposite to the screen plate are arranged on the lower end of the air duct above the screen plate. The other end of the air duct is closed. An air draft duct is arranged on the casing top of the discharge outlet of the screen box. The other end of the air draft duct is connected with the air inlet of the exhaust fan. At least two air ducts are arranged above the screen plate. The air induced duct and the air draft duct which are respectively connected with the screen box and the casing of the discharge outlet are corrugated ducts. The vibrating screen has the advantages that the screen hold is difficult to block, and the screening efficiency is high, applicable for screening materials.
Description
Technical field:
The present invention relates to a kind of material sieving technology, particularly a kind of vibrating screen under groove.
Background technology:
The blast furnace vibrating screen under groove screens materials such as the coke of going into the stokehold, pelletizing, assorted ore deposits in the metallurgy industry, because that some raw materials contain moisture is bigger, bonds on sieve plate, and sieve aperture stops up, and the screen(ing) machine screening efficiency is declined to become the chronic disease of sieving under the blast furnace groove.
Summary of the invention:
The purpose of this invention is to provide a kind of sieve aperture and be difficult for stopping up the high vibrating screen under groove of screening efficiency.Technical scheme of the present invention is, a kind of vibrating screen under groove, comprise screen box, it is characterized in that: be provided with above screen box feeding mouth end that the airduct above the sieve plate is communicated with in induced duct and the screen box, the induced duct other end is connected with the air outlet of blower fan, the air inlet of this blower fan is connected with the outlet of iron winds furnace exhaust, it is relative with sieve plate that the bottom of the airduct of sieve plate top is evenly equipped with radial hole, the other end sealing of this airduct, top at screen box discharging opening housing is provided with exhaust column, and the other end of this exhaust column is connected with the air inlet of air exhauster.The airduct of sieve plate top has 2 at least.Induced duct and the exhaust column that is connected with the discharging opening housing with screen box is bellows respectively.The present invention has the remarkable advantage that sieve aperture be difficult for to stop up, screening efficiency is high compared with the prior art.
Description of drawings:
Fig. 1 is the structural representation of vibrating screen under groove of the present invention, and Fig. 2 is the partial enlarged drawing of Fig. 1.
The specific embodiment:
In conjunction with above accompanying drawing the present invention is described in detail, groove sieve sieve pore blockade down causes greatly owing to material contains moisture, if the moisture removal blockage problem of material can be able to be resolved, yet because the inventory of required screening is very big, the heat energy that is consumed is huge, and is very uneconomical.And the temperature of the waste gas that the iron winds fire grate goes out is discharged into about 200 ℃ in the air and slatterns, and has increased the fuel factor of atmosphere.The present invention utilizes high-temp waste gas that the iron winds fire grate goes out to remove moisture in the material.For this reason, on the top of the feeding mouth end of screen box 1 induced duct 3 being set is connected with the air outlet of blower fan, the air inlet of this blower fan is connected with iron winds furnace exhaust exhaust outlet, in screen box sieve plate 2 above be provided with a plurality of airducts parallel 4 with sieve plate, the one end is connected with induced duct 3, other end sealing is provided with exhaust column 6 on the top of the discharging opening 5 of screen box and is connected with air exhauster.The bottom of the airduct 4 of sieve plate top is evenly equipped with that radial hole (referring to Fig. 2) is relative with sieve plate, and the quantity of airduct 4 can be definite according to the width of sieve plate, is purpose can make material on the sieve plate be subjected to evenly that hot blast blows.Induced duct 3 and exhaust column 6 flexibly connect with screen box and being connected to of discharging opening housing, as bellows.It is fine that this scheme is removed the material moisture effect through test.
Claims (3)
1, a kind of vibrating screen under groove, comprise screen box, it is characterized in that: be provided with above screen box feeding mouth end that the airduct above the sieve plate is communicated with in induced duct and the screen box, the induced duct other end is connected with the air outlet of blower fan, the outlet of the air inlet of this blower fan and iron winds furnace exhaust is connected, and it is relative with sieve plate that the bottom of the airduct of sieve plate top is evenly equipped with radial hole, and the other end of this airduct seals, top at screen box discharging opening housing is provided with exhaust column, and the other end of this exhaust column is connected with the air inlet of air exhauster.
2, a kind of vibrating screen under groove as claimed in claim 1 is characterized in that: the airduct of sieve plate top has 2 at least.
3, a kind of vibrating screen under groove as claimed in claim 1 or 2 is characterized in that: induced duct and the exhaust column that is connected with the discharging opening housing with screen box is bellows respectively.
