Abstract
The utility model discloses a vibration sieve under a sink, which relates to a sieving technology. The utility model aims to provide a vibration sieve under a sink, which has high sieving efficiency and non-easy stopped sieve pores. The vibration sieve adopts the technical proposal that a straining box is included, the upper part of the feed opening end of the straining box is provided with an induced air pipe communicated with air pipes at the upper part of a sieve plate in the straining box, the other end of the air pipe is connected with the air outlet of a blower, the air inlet of the blower is connected with the waste gas outlet of an iron wind furnace, radial holes are evenly distributed on the lower parts of the air pipes at the upper part of the sieve plate to be opposite to the sieve plate, the other ends of the air pipes are closed, the top of the discharge hole shell of the straining box is provided with an exhaust pipe, and the other end of the exhaust pipe is connected with the air inlet of an exhaust fan. At least two air pipes are arranged at the upper part of the sieve plate. The induced air pipe and the exhaust pipe respectively connected with the straining box and the discharge hole shell are corrugated pipes. The vibration sieve under a sink is used for sieving materials.
Description
Technical field:
The utility model 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 utility model provides a kind of sieve aperture and is difficult for stopping up the high vibrating screen under groove of screening efficiency.The technical solution of the utility model 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 utility model 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 the utility model vibrating screen under groove, and Fig. 2 is the partial enlarged drawing of Fig. 1.
The specific embodiment:
In conjunction with above accompanying drawing the utility model 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 utility model is exactly to utilize 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.
