Abstract

The utility model provides equipment used for melting steel slag heating stuffiness process, comprising a concrete tank and a device cover, characterized in that the concrete tank (2) is provided with an inner wall (3); the inner wall (3) and the concrete tank (2) are separated by a heat insulation layer (3-4); the inner wall (3) is fixed to the concrete tank (2) by a fixed part (3-1); the inner wall (3) and the concrete tank are provided with a gas discharge port (3-2) and a water discharge port (3-3). The equipment is used in the steel slag below 1600 DEG C discharged from the converter. The steel slag is directly put into the device and the f-CaO, f-MgO in the steel slag of steam produced by the automatic water-spray carries out the hydration reaction to cause the volume expansion and to be powdered, thus realizing the 100 percent source utilization of the steel slag. The equipment of high temperature resistance, which does not need to put the steel slag on the ground for cooling to 800 DEG C and then move to the heating stuffiness device, has the advantages of saving the land, reducing the intermediate link, reducing construction and construction investment, having good powdering effect of the steel slag, low maintenance cost, safety and reliability.

Description

The vexed processing equipment of a kind of molten steel slag heat

Technical field

The utility model relates to used for steel slag treatment equipment, the vexed processing equipment of particularly a kind of 1600 ℃ of molten steel slags heat.

Background technology

At steel industry, the utilization ratio of slag has only 10%, and a large amount of smelting slag heaps are abandoned, land occupation, contaminate environment, waste resource.Therefore need clear up into Ca (OH) to f-CaO, f-MgO in the slag ₂, Mg (OH) ₂, eliminate the unstable of slag, realize slag " zero release " recycling, realize energy-conservation, reduction of discharging, recycling economy, Sustainable development.

The applicant once obtained the vexed processing of a kind of hot steel slag heat novel patent of equipment ZL200420058581.6, the hot disintegrating device that this patent adopts is applicable to the used for steel slag treatment below 800 ℃, play and clear up f-CaO in the slag, f-MgO unstable, its slag iron separation property is good, easy to maintenance.But it is rack-mount that the weak point of finding this appliance arrangement in practice is a wallboard, and wallboard adopts cast iron plate, and easy impact damage and coming off when excavator is slagged tap is changed frequent.

Need when using this equipment high temperature is reached 1600 ℃ the slag ground on the scene of tumbling, be cooled to below 800 ℃, just can advance hot disintegrating device and handle, if 1600 ℃ slag is directly packed into, this backplate support temperature distortion can make backplate come off naturally, and concrete wall destroys.Original patented technology need take and turn over slag cooling place in a large number, and shovel fortune process produces dust polluting environment, and shovel fortune equipment is fragile, and the production upkeep cost increases, and construction investment increases.

The utility model content

It is that 1600 ℃ of slags are directly packed in the hot vexed equipment that the purpose of this utility model provides a kind of temperature, land the refrigerative process procedure to remove slag, to improve the performance of the vexed equipment non-refractory of original heat, cause molten steel slag to pour the equipment deformed damaged into, backplate breaks during collision, the concrete foundation shortcake splits, out of use shortcoming.Compare with the vexed equipment of original heat, the utlity model has durable 1600 ℃ high temperature, equipment does not damage, and is not afraid of the excavator collision, and the production maintenance cost is low, and the good advantage of security.

The purpose of this utility model realizes by following technical scheme.

The utility model is the vexed processing equipment of a kind of molten steel slag heat, comprises concrete sump and appliance cover, it is characterized in that: in described concrete sump inwall is housed; Separate through thermofin between described inwall and the concrete sump, inwall is fixed in the described concrete sump with fixation kit; On inwall and concrete sump, have venting hole and water vent.

Described fixation kit comprises bolt, nut, sleeve, and described sleeve is positioned at the wall of concrete sump, with the described telescopic screw bolt and nut that passes inwall is fixed in the concrete sump.

Described inwall is made up of some backplates.

On described concrete sump, have water sealed tank, on described water sealed tank, be stamped appliance cover.

On described equipment, automatic control system is housed.

In sum, the utility model is high temperature resistant, durability is higher, the slag of 1600 ℃ of high temperature directly can be poured into, carries out hot vexed processing.Can improve hot vexed processing efficiency and quality; Equipment is not fragile, and maintenance cost greatly reduces, and security is good.
