Description

sintering machine tail guide chute

Technical Field

The invention relates to a guide chute at the tail of sintering machines, belonging to the technical field of sintering production equipment in the metallurgical industry.

Background

The guide chute at the tail of the sintering machine is positioned between the tail of the sintering machine and a single-roll crusher and is which is a very important link on a sintering production line, and the reliability of the guide chute is very important for the stability of the whole sintering production, generally, the relative height difference between the table top of the sintering machine and the trolley top of the single-roll crusher is more than four meters, when the trolley of the sintering machine discharges materials, the temperature of hot sintering ores is between 750 and 850 ℃, the weight of the sintering ores discharged by each trolley can reach seven tons, the fall reaches three meters, the impact force is quite large, the discharge end of the guide chute is washed by the high-temperature sintering ores for a long time, the abrasion is serious, and the guide chute is uninterrupted in twenty-four hours at high temperature, so the abrasion of the equipment is accelerated, the service life of the guide chute is short, particularly, the square steel at the upper part and the square steel at the lower part of the guide chute are easily directly impacted by the hot sintering ores, the abrasion is the most serious, the adjustment treatment needs to be carried out every three months, the replacement needs to be carried out every half year, the repair from the maintenance, the cleaning of the welding.

Disclosure of Invention

The invention aims to provide sintering machine tail guide chutes, which can prolong the service life, reduce the maintenance times, improve the operation rate of a sintering machine, save the cost and solve the problems in the background technology.

The technical scheme of the invention is as follows:

sintering machine tail guide chutes comprise chutes and bases, wherein the chutes are fixed on the bases and are formed by combining a back plate, two side plates and a bottom plate, a plurality of blanking pockets are sequentially arranged in the chutes from top to bottom and form a multi-stage trapezoid, the back plate inside the chutes is provided with a back plate buffering pocket, the side plates inside the chutes are provided with side plate buffering pockets, and the back plate outside the chutes is provided with a receiving chute.

The inclination angle between a multi-stage trapezoid formed by a plurality of blanking pockets in the trough and the bottom plate is 40-45 degrees.

And whole bodies are formed by pouring a plurality of blanking pockets, a back plate buffering pocket and a side plate buffering pocket in the trough through pouring materials.

And a reinforcing rib is arranged between the material receiving groove and the back plate.

The invention has the beneficial effects that: the production process requirement is met, the abrasion resistance and the impact resistance are realized, the service life is as long as more than two years, the sintered ore can smoothly fall to a single-roll crusher, and the operation rate of a sintering machine is improved.

in the figure: 1. sintering machine tail star wheel; 2. a discharge trolley; 3. a material guide chute; 4. a crusher; 5. a trough; 6. a base; 7. a material receiving groove; 8. pouring a material; 9. a blanking pocket; 10. a back plate buffer pocket; 11. a side plate buffer pocket; 12. a back plate; 13. a side plate; 14. a base plate.

Detailed Description

The invention is further illustrated by way of example at in the following description taken in conjunction with the accompanying drawings.

Referring to the attached drawings 1-5, sintering machine tail guide chutes comprise a chute 5 and a base 6, wherein the chute 5 is fixed on the base 6, the chute 5 is formed by combining a back plate 12, two side plates 13 and a bottom plate 14, a plurality of blanking pockets 9 are sequentially arranged in the chute 5 from top to bottom, the plurality of blanking pockets 9 form a multi-stage trapezoid, a back plate buffer pocket 10 is arranged on the back plate 12 in the chute 5, a side plate buffer pocket 11 is arranged on the side plate 13 in the chute 5, and a material receiving groove 7 is arranged on the back plate 12 outside the chute 5.

Referring to fig. 1-4, the tail guide chute 3 of the sintering machine is composed of a chute 5, a base 6 and a castable 8, wherein the chute 5 is composed of a back plate 12, two side plates 13 and a bottom plate 14, and the base 6 is fixed by a hilt-shaped steel plate to prevent the chute 5 from shifting in the process of sinter blanking impact.

A plurality of unloading pockets 9 have been made to silo 5 inside, a plurality of unloading pockets 9 constitute multistage trapezoidal, inclination between multistage trapezoidal and the bottom plate 14 is 40-45 degrees, unloading pocket 9 adopts GY-3 high-strength ceramic wear-resistant material, carry out the integral casting, this material is rapid hardening wear-resistant material, the adhesion is strong, the wholeness can be good, after using sections time, when local need be mended, only need demolish this position, then carry out the local casting again, later the short time toast can put into production and use, convenient construction, easy maintenance.

And buffer material pockets are respectively welded on the back plate 12 and the two side plates 13 in the trough 5, and are also poured by using pouring materials, so that the impact abrasion of the sinter to the side surface and the back surface in the discharging process is avoided.

The material receiving groove 7 on the back plate 12 outside the material groove 5 is fixed through the inclined triangular tie bars and has the function of preventing the sinter from extruding and impacting the base to cause the base to be completely broken.

Fig. 5 is a schematic view of the using state of the invention, and the discharging trolley 2 pours the sintering ore onto the material guiding groove 3 along with the rotation of the tail star wheel 1 of the sintering machine, and finally rebounds to the crusher 4 to crush the sintering ore.
