(54) КОЛСХ:НИКОВАЯ РЕШЕТКА КОНВЕЙЕРНЫХ MAIUHH(54) KOLSKH: NICK GRID CONVEYOR MAIUHH

Изобретение относитс к оборудованию аглсмераЦионг ых и обжиговых конвейерных машин и может быть использовано в черной и цветной металлургии,The invention relates to the equipment of the aggcromera Ziongy and roasting conveyor machines and can be used in ferrous and nonferrous metallurgy,

Известно устройство дл ксации колосников тележек обжиговых машин, в котором дл стабилизации рассто ни между колосниками используетс попарно соединенные подпружиненные толкатели l .A device for grating the grates of kiln carts is known, in which pairwise connected spring tappets l are used to stabilize the distance between the grate bars.

К недостаткам указанного устройства относитс то/ что при мощных пружинах колосники, особенно близко расположенные к пружинам,тер ют подвижность относительно друг- друга, а при слабых пружинах не достигаетс стабилизаци величины щелей между колосниками. KjpoMe того, нельз установить оптимальную -характеристику пружин, так как услови , в которых экJйплyaTиpyeтc колосникова решетка, нестационарны, измен ютс липкость и влажность шихты, температура шнхты и агромерата на колосниковой решетке , а также температура самих пружин и т.п.The disadvantages of this device include the fact that, with powerful springs, the grate bars, especially close to the springs, lose mobility relative to each other, and with weak springs, stabilization of the size of the gaps between the grate bars is not achieved. Moreover, it is not possible to establish an optimal characteristic of the springs, since the conditions in which the grate is uneven, the stickiness and humidity of the charge, the temperature of the graft and agromerate on the grate, and the springs themselves change, etc.

Известен механизм дл т подбивгки колосников, т.е. дл стабилизации рассто ни между ними, включающий самосто тельный привод, ротор, рабочие органы и множество вход щих деталей 2. A mechanism is known for tilling grates, i.e. to stabilize the distance between them, including an independent drive, a rotor, working bodies, and many incoming parts 2.

К недостаткам этого механизма сл-едует отнести ее сложность, ненадежность и необходимость обслуживани . .The disadvantages of this mechanism include its complexity, unreliability and the need for service. .

Известна также колосникова решетка , содержаща колосниковые балки и размещенные на них колосники с захватами , выполненные с клиновыми опор10 ными поверхност ми, причем контакт колосника с подколосниковыми балками происходит цо линии PJ. .The grate grate is also known, containing grate beams and grate placed on them with grippers, made with wedge bearing surfaces, and the grate contact with the beams occurs with a PJ line. .

Однако така конструкци коласниковой решетки не позвол ет обеспечить However, such a grab structure does not allow

15 самосто тельного стремлени к перемещению Б одну сторону всех колосников каждого р да на опорных балках при переходе последних с нижней ветки направл ющих конвейерной машины 15 of the individual striving to move B one side of all the grates of each row on the support beams when the latter passes from the lower branch of the guides of the conveyor machine

Цель изобретени - стабилизаци рассто ни между колосниками.The purpose of the invention is to stabilize the distance between the grate bars.

Claims

This goal is achieved by the fact that, in the lattice containing the undercutting rollers and grates with grips placed on them, the grate supporting surfaces arranged inside the grips are made on one of the half grips relative to the vertical longitudinal plane of the symmetrical grid of the grate. Grate bars are positioned on one side with supporting surfaces. Figure 1 shows the proposed grate, General view; Ya figure 2 - section aa in figure 1 nor fir.Z - grate; figure 4 - section bb In fig.Zg figure 5 - section bb In fig.Z; Fig.6 - 11 is a diagram of the crossfire grate when turning spec. trolleys; in fig. 12 and 13 are versions of the support surfaces. The grate consists of spikes 1, beams 2, sides 3 and castles 4. The supporting surfaces of the grate grippers are displaced in one direction from the vertical plane passing along the grate body through its center of gravity, the grate bars are arranged in rows with the arrangement displacement of support surfaces in one direction. Lattice works in the following way. When the support beams with the grate move from the upper branch of the yoftoftx to the lower one and vice versa, the grate hangs on the supporting beam on the supporting surface of the hook. Due to the fact that the supporting surface of the grip is offset from the center plane, the grate of the grate warps to such a position that the supporting surface of the grip and the center of gravity are located in the same vertical plane. When a pair of support beams are out of radius onto the lower branch of the guide bars, the grate bars are already resting on another side of the sheds on the base, while remaining skewed relative to them. When moving from the lower branch to the next radius, the grate bars hang on the beams by different hooks, and the center of gravity is once again shifted to the vertical plane passing through the supporting surface of the hook. Thus, when moving from one rack to one of the guides for the support beams and the other radius, the grate moves along the support beams due to the fact that the support surfaces D and C (Fig. 3) of the chains are made according to the invention. The diagrams in FIGS. 6-11 are explained in terms of how the grates move along the support heads in the case of surfaces C and D (fig. 3) of the grates in accordance with the invention, provided the support beams move along the guides from top to bottom and again on the top line. In the case of burnout, thinning or falling out of individual grates in rows, the presence of grips with one-sided arrangement from their supporting surfaces relative to the vertical plane, passing along the body of the grate through its center of gravity, and the orientation of the grate in one row allows one way offset quick ejection of the formed gap between the grate, i.e. stabilizing the distance between the grate bars. Thus, a slot is formed near the bead, where it can be closed in a known manner, for example, a bead, a bar, etc. The bead structure (Fig. 1) closes the gap above, formed because the whole grid of bars towards the sides of the board. The application of the proposed lattice provides a significant reduction in spillage of materials sintered or baked on conveyor machines and reduces harmful drifts. Claim 1. Kolosnikova ratenka of conveyor machines, containing under-beam beams and grate placed on them with grippers, characterized in that, in order to stabilize the spacing between the grates, the grate supporting surfaces. located inside the grippers, are made on one of the halves. cotton wool relative to the vertical pro-longitudinal plane of symmetry of the grate passing through its center of gravity. 2. Lattice pop.1, which is related to the fact that the grate bars are arranged with supporting surfaces in one direction. Sources of information taken into account when examining 1.
