Abstract
The utility model provides a lining graphite prevention plate for a polycrystal ingot furnace carbon felt. The lining graphite prevention plate is characterized in that a graphite prevention plate is attached to the upper part of the inner surface of a cavity of the polycrystal ingot furnace carbon felt. The graphite prevention plate is additionally arranged on the inner surface of the polycrystal ingot furnace carbon felt, so that the impact of airflow and heat to the carbon felt can be reduced, the service life of the carbon felt can be prolonged, and the influence of the dust on the carbon felt on an ingot can be reduced.
Description
Technical field
The utility model relates to the graphite applied technical field, particularly relates to a kind of polycrystalline ingot furnace carbon felt liner graphite protective shield.
Background technology
The carbon felt is widely used in polycrystalline ingot furnace thermal field owing to have excellent heat retaining property, processibility, purity, advantage such as heat-resisting.
Existing polycrystalline silicon ingot or purifying furnace carbon felt structure as shown in Figure 1; carbon felt surface does not all have sfgd.; in the ingot casting process, be subjected to air-flow and thermal shocking effect aging serious; because air-flow is mainly discharged from upper side in the crucible; upper part carbon felt of body of heater is subjected to airflow scouring particularly serious, has reduced the work-ing life of carbon felt to heavens.
The utility model content
The purpose of this utility model is to propose a kind of polycrystalline ingot furnace carbon felt liner graphite protective shield, reduce the suffered gas shock at high temperature of carbon felt, cover with graphite cake in side heat-insulation cage medial region, intercept air-flow directly to the impact of carbon felt, thereby increase the work-ing life of carbon felt, and reduce reason such as carbon felt dry linting to the influence of ingot casting.
The utility model proposes a kind of polycrystalline ingot furnace carbon felt liner graphite protective shield, it is characterized in that the internal surface top dress of described polycrystalline ingot furnace carbon felt cavity posts the graphite protective shield.
More preferably, described graphite protective shield uses fastening piece to be connected with the internal surface of polycrystalline ingot furnace carbon felt.
More preferably, described graphite protective shield thickness is greater than 0-10mm.
More preferably, described graphite protective shield is at least 4.
More preferably, the described graphite protective shield position that mutually combines arranges bridging.
The utility model reduces air-flow and heat to the impact of carbon felt, thereby prolongs its work-ing life by adding one deck graphite protective shield at polycrystalline ingot furnace carbon felt internal surface, and reduces carbon felt dust to the influence of ingot casting.
Description of drawings
Can describe in detail and appended graphic being further understood by following utility model about advantage of the present utility model and spirit.
Fig. 1 is the packaging assembly synoptic diagram of existing polycrystalline ingot furnace carbon felt;
Fig. 2 is the packaging assembly synoptic diagram of the utility model polycrystalline ingot furnace carbon felt.
Embodiment
Describe specific embodiment of the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 2, in a preferred embodiment of the present utility model, polycrystalline silicon ingot or purifying furnace carbon felt is surrounded the square furnace chamber of hollow on four sides by some dull and stereotyped carbon felts, dress posts four big graphite protective shields 1 and four little graphite protective shields 2 on the internal surface top of carbon felt cavity, the thickness of graphite protective shield is 3mm, highly account for 1/4 of carbon felt height overall, with bolt the graphite protective shield is fixed on the carbon felt, make it be close to the internal surface of carbon felt.Every graphite protective shield arranges bridging in the position that their edge mutually combines, to guarantee that not having the surface omits.Usually, the graphite protective shield uses bolt or other fastening pieces to be connected with the internal surface of polycrystalline ingot furnace carbon felt, and graphite protective shield thickness is greater than 0-10mm, and the graphite protective shield is at least 4.Present embodiment preferably resolves the polycrystalline ingot casting carbon felt that runs in the reality and shifts to an earlier date problem of aging, has improved the polycrystalline ingot quality.
Described in this specification sheets is preferred embodiment of the present utility model, and above embodiment is only in order to the technical solution of the utility model to be described but not to restriction of the present utility model.All those skilled in the art comply with design of the present utility model by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be within scope of the present utility model.
