Description

The invention relates to the dispensing of poorly flowing lumpy materials and can be used by 3 foundries to deliver the charge, as well as in the metallurgical, mining and construction pro- cesses NBHmineHHocTH. A device for dispensing materials containing a hopper and a device for displacing the material are known. However, this the device is unreliable in operation, since it is possible that the uniek is clogged with material A device for dispensing poor lumpy materials is known, comprising a frame and a bunker and feeder t23 mounted thereon. However, the known device is not reliable in operation, since it is possible for the material to hang. The aim of the invention is to improve the reliability of operation by eliminating material sticking. The goal is achieved by the fact that in a device for dispensing poorly Lumpy materials containing a frame and a bunker and a feeder fixed on it, the bunker case has the shape of a truncated cone mounted with a large base downwards and equipped with an auger strengthened on its inner surface. moving material tag. In addition, the feeder is a rotatably mounted drum, on the inner surface of which the spiral guides are reinforced with yoseyichivayuyuschim in the course of the material moving in pitch, Ya the drawing shows a device for issuing poorly flowing bulk materials, longitudinal section. The device includes a frame 1, on which is fixed a bunker 2, made in the form of a truncated cone, mounted with a large base 5 downwards, inside which the conical auger 3 is fixed with a vertical downward pitch, the screw 4 of which forms a spiral channel with the wall of the hopper, the geometric dimensions of which are uniform increase on exit. The bunker has a feed funnel 5 in the upper part, for example, for unloading the container), and in the lower part is the outlet 6. -Patel is sewed in the form of an inclined rotating state drum 7 with spiral-shaped lines 8 and drive (not P Cossack). The spiral-shaped directions are made, for example, from a U-shaped profile and are fixed on the inner surface of the drum with an increasing step towards the exit. The outlet bin is installed on the side of the raised end of the drum. In the middle part of the drum surface, there are holes for sifting out fine coke, lime, and sludge of metal charge. The rotating drum is inclined at an angle smaller than the angle of repose of the material. The auger blade is inclined to its vertical axis so that the angles at the base in any section of the channel are equal to each other, this is the main condition for ensuring reliability of the material to the drum 7, as centrifugal forces occur during material movement, pressing the material to bunker wall and friction increase. And the inclination angle of the helical latch 4 in the loading zone is no less than the friction angle of sliding of the material being loaded on the material of the bunker. The device works as follows. Poorly flowing lumpy material is fed into the hopper hopper 5, from where it falls on the screw blade 4, into a spiral channel through which gravity slides down to the outlet 6. in this case, they are evenly distributed throughout the channel, since its geometrical dimensions gradually increase to the output. Then the material enters the inclined rotary drum 7 with spiral-shaped guides 8. Due to the force of friction and the presence of Kideh 8 in the drum, pieces of material that fall into the inlet of the inclined drum remain in it and block the outlet of the bunker b. When the drum rotates in the direction opposite to the winding of the spiral-shaped guide 8, the material rises up along the drum's surface until its adhesion to the surface disappears and slides down along the guides, while pieces of material op are oriented along the guides, aligning the flow, since the pitch of the helix is increased at the exit from the drum, then the material is dispersed as it progresses over an increasingly large surface, while the translational speed increases and thus the layer of the material decreases. The thickness of the layer at the outlet of the drum is governed by its slope, which is selected during adjustment. The intensity of the flow at a constant slope is determined by the rotational speed of Barab I11239544
