Technical field:
the utility model relates to the technical field of industrial silicon production equipment, in particular to an open-hearth eye protection device for an ore furnace.
The background technology is as follows:
In the process of smelting and producing silicon by using a submerged arc furnace, raw materials added into the furnace are melted into liquid state at high temperature, and after smelting, furnace eyes of the submerged arc furnace are required to be opened (namely, the furnace eyes are opened) so that molten silicon liquid flows out of the furnace eyes into a ladle for subsequent ingot casting treatment; after the silicon liquid is discharged, the furnace hole is plugged by stemming, so that the hole plugging operation of the submerged arc furnace is completed.
At present, when an ore-smelting furnace is opened, steel bars are usually adopted for operation manually, but sparks can be splashed from the furnace eyes in the operation process, namely high-temperature slag particles can be splashed from the furnace eyes, and serious potential safety hazards exist.
The utility model comprises the following steps:
The utility model aims to provide an ore-smelting furnace open-eye protection device which can effectively shield splashed sparks so as to reduce potential safety hazards.
The utility model is implemented by the following technical scheme: a protection device for an open hearth of an ore-smelting furnace comprises a tapping baffle plate movably arranged right in front of the hearth of the ore-smelting furnace; the furnace discharging baffle is provided with an opening corresponding to the furnace hole, a cross beam is detachably connected to the upper edge of the opening through bolts, and a blocking curtain for blocking the opening is fixed on the cross beam.
Further, the curtain is composed of a plurality of chains which are arranged side by side and made of transparent high-temperature resistant materials.
Further, guide rails are respectively fixed on the ground above and below the tapping baffle, a plurality of pulleys are installed on each guide rail at equal intervals, and the tapping baffle is arranged between the upper group of pulleys and the lower group of pulleys.
Further, hooks are respectively fixed on the tapping baffles at the two sides of the opening.
The utility model has the advantages that: when the furnace hole is opened, the discharging baffle is moved to the position right in front of the furnace hole, a worker passes through the baffle through the furnace hole, sparks are splashed out in the process, but the sparks cannot splash on the body of the worker under the shielding of the discharging baffle and the baffle, so that an effective protective effect is achieved, and potential safety hazards are reduced; after the furnace eyes are opened, silicon liquid flows into the platform bag along the chute; and after the silicon liquid is discharged, the furnace hole is blocked.
Description of the drawings:
Fig. 1 is a schematic structural view of the present utility model.
FIG. 2 is a schematic view of the present utility model in use.
The components in the drawings are marked as follows: the ore-smelting furnace comprises an ore-smelting furnace 1, furnace eyes 2, a furnace outlet baffle 3, an opening 4, a cross beam 5, a baffle 6, a guide rail 7, pulleys 8, hooks 9 and a table bag 10.
The specific embodiment is as follows:
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
