Abstract

The utility model provides a sinter pre-processing device, comprising a material hopper and a chute arranged below the material hopper. The utility model is characterized in that the upper part of the material hopper is provided with a grate plate with grids at a certain angle along the horizontal direction; the grate plate is provided with a vibration block which is connected with a motor. The utility model can effectively crush and cool the sinter at high temperature and high viscidity, and large solid articles in the sinters are avoided entering the chute and the roller, thus prolonging the service life of the equipment and leading the production to be continuously carried out.

Description

The slag pretreatment unit

Technical field

The utility model relates to a kind of slag pretreatment unit, specifically, is a kind ofly can carry out pretreated device to high temperature, full-bodied slag.

Background technology

Drum process metallurgical slag treating processes flows to molten state, slag with certain flowability the feeding unit that hopper and chute form from slag ladle, enters cylinder by it then.Because the Chemical Composition of slag and temperature is different, the flowing property of slag is also different.When handling mobile poor, easy agglutinating slag, the bonded gradually slag of original replacing formula feeding unit (hopper and chute) meeting stops up even is blocked, and, often be mingled with unfused large-sized solid thing such as cold bloom in the high viscosity slag, the large-sized solid thing easily blocks chute, cause slag treatment production to be forced to interrupt, advance the slag device and then change frequently, influence the charging and the processing of follow-up slag; Solids such as cold bloom that part is mingled with also enter in the cylinder easily, and because of its out-of-shape, the wedge angle position can produce heavy wear to internal unit, influences the life-span of cylindrical shell.Above-mentioned high viscosity slag carries out closed processing because of can't directly entering in the cylinder, for prolonging the work-ing life of equipment, common way is that it is tumbled in the slag field, wait to sprinkle water the cooling after reinstall the container that has grid, by grid the large-sized solid inclusion is separated, at last slag is poured in the drum process slag processing apparatus from container and handled, but in loading process, produce a large amount of airborne dusts, the severe contamination surrounding enviroment.

Summary of the invention

The purpose of this utility model is to provide a kind of slag pretreatment unit, it can effectively be pulverized, cool off high temperature, full-bodied slag, large-sized solid thing in the isolated slag enters chute and cylinder, thereby can prolong the work-ing life of equipment, production can be continued carry out.

For achieving the above object, the technical solution of the utility model is: a kind of slag pretreatment unit is provided, it comprises hopper and is positioned at the chute of its below, characteristics are, above hopper, settle one and horizontal direction have angle and have the grate plate of grid, this grate plate is provided with vibrating mass, and this vibrating mass is connected with a motor.

Said vibrating mass is connected by a versatile spindle with motor;

Between described hopper and chute, also be provided with one and carry the e Foerderanlage of slag to chute;

The utility model also comprises an infrared inductor that is arranged on the slag pan feeding passage, and this infrared inductor is connected with described motor, e Foerderanlage circuit;

Than low side, a guide plate that tilts is set also in the grate plate that tilts, the beveled end of this guide plate also is provided with a container;

On e Foerderanlage, a refrigerating unit is set also.

Effect of the present utility model is: pass through oscillating plate, make slag when dropping to grate plate, be broken, loose, the little slag of volume after the preliminary fragmentation falls from the gap of grate plate and is lowered the temperature by vibration, flow in the cylinder and handle, prolonged the work-ing life of cylinder, and motor drives the vibrating mass vibration by versatile spindle, makes motor to reduce the damage of high-temperature slag to motor away from high-temperature slag; The grate plate that is adopted can be held back the large-sized solid inclusion again, the grate plate that tilts adds that vibration helps the large-sized solid inclusion and produces and jump and along the surperficial landing of grate plate, easily it is separated from slag, reclaims, avoided the large-sized solid inclusion to enter in the cylinder again the cylinder internal structure is caused damage.Be provided with cooling system in the e Foerderanlage, coolconveyer makes it at high temperature guarantee good lubricating status effectively.Adopt this utility model, can reduce the problem of environmental pollution that former high viscosity slag treatment produces greatly, also have and invest advantages such as little, effective.And energy assurance equipment is at the medium-term and long-term trouble-free service of hot environment.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

Following according to Fig. 1, specify a better embodiment of the present utility model.

As shown in Figure 1, the utility model comprises hopper 7, on hopper 7, be provided with one and horizontal direction have angle, the grate plate 4 that has grid, vibrating mass 5 is set on the grate plate 4, and vibrating mass 5 is connected with motor 6 by versatile spindle N, and has an infrared inductor 1 to be connected with these motor 6 circuit; Below hopper 7, also have an e Foerderanlage 8, this e Foerderanlage 8 is connected with infrared inductor 1 circuit; Below this e Foerderanlage 8, chute 2 is set, chute 2 and cylinder 3 communicate; At the low side of the grate plate 4 that tilts, hopper 7 an other guide plate 10 and the containers 11 of also being provided with.

When toppling over slag, infrared inductor 1 is sensed the charging signal, starter motor 6 and e Foerderanlage 8, motor 6 drives vibrating mass 5 by universal shaft coupling device N and rotates, make the grate plate 4 of inclination produce vibration, slag is at first fallen on the grate plate of vibrating 4 and is crashed to pieces because of vibration, slag 13 after the being crashed to pieces hopper 7 of flowing through from the gap of grate plate 4 falls on the e Foerderanlage 8 that is rotating, the temperature of slag reduces a little in transportation, the viscosity of slag 13 also progressively reduces, and waltzs through charging chute 2 and enter in the cylinder 3 and be further processed; And be trapped within on the grate plate 4 large-sized solid thing 12 the vibration grate plate 4 effect under, generation is beated and to the lower end landing of grate plate 4, be slipped on the guide plate 10, and be slipped in the container 11 by deadweight again, finish the sepn process of large-sized solid thing 12 and slag 13 along guide plate 10.At the whole preprocessing process of slag 13, e Foerderanlage 8 is in cycle rotation, and top touches high-temperature slag 13 and the temperature rising, and when turning to the bottom, the cooling system 9 ejection water coolants that are arranged on e Foerderanlage 8 inside cool off it.

The utility model utilization vibration reaches auxiliary slag input and the isolating purpose of solid simultaneously.Grate plate 4 can be fixed, also can be designed to portablely, can move as required or rotate.
