Abstract
The utility model discloses a sintering furnace air-exhausting structure which comprises a furnace body (30) of a sintering furnace, an air-exhausting pipe and an air-exhausting pipe outlet (12). The sintering furnace air-exhausting structure is characterized in that an air outlet pipe (20) of the sintering furnace is arranged on the furnace body (30), the air-exhausting pipe (10) which has a horn-cover shape structure is arranged above the air outlet pipe (20), the air outlet pipe (20) and the air-exhausting pipe (10) are independent, the caliber of an air-exhausting pipe port (11) of the air-exhausting pipe (10) is larger than that of an air outlet pipe port (21) of the air outlet pipe (20), and the height of the distance between the air-exhausting pipe port (11) and the furnace body (30) is larger than that of the distance between the air outlet pipe port (21) and the furnace body (30). The sintering furnace air-exhausting structure can better avoid the unstable state of internal thermal field as pipelines are directly connected to take a part of heat in the sintering furnace away when the wind strength of air exhaustion is bigger, thereby achieving the aims of increasing the stability in a cavity body of the sintering furnace and improving the sintering qualification rate of products.
Description
Technical field
The utility model relates to a kind of sintering furnace exhausting structure, especially a kind of exhausting structure of using at the solar silicon wafers sintering furnace.
Background technology
In the production process of silicon solar cell, needing to enter last sintering circuit through printing back electrode, oven dry back electrode, printing back of the body electric field, oven dry back of the body electric field, after making serial operations such as grid; And the quality of sintering circuit quality control directly has influence on the final quality of product, whole sintering circuit is finished in sintering furnace, temperature in the body of heater is controlled to an important step of operation for this reason, wherein also directly have influence on the stability of thermal field in the sintering furnace cavity for the exhaust column design quality of sintering furnace, the exhaust column structure employing mode of existing sintering furnace is exhaust column and the direct-connected mode of sintering furnace, though can effectively carry out exhausting like this, but when exhausting wind-force strong partially situation bigger than normal occurring, direct-connected mode is taken away the major part heat in the sintering furnace cavity easily, cause sintering furnace inside cavity thermal field instability, influence sintering quality.
The utility model content
The utility model for the exhaust column that solves existing sintering furnace when exhausting wind-force strong partially situation bigger than normal occurring, exhaust column is taken away the part heat in the sintering furnace cavity easily, a kind of exhausting actual effect that can better handle exhaust column that causes the unsettled present situation of sintering furnace inside cavity thermal field and provide can better guarantee the sintering furnace exhaust column structure of the stability of sintering furnace inside cavity thermal field.
The utility model is to solve the problems of the technologies described above the concrete technical scheme that is adopted to be: the shaft of sintering furnace, exhaust column, exhaust column outlet, shaft is provided with the escape pipe of sintering furnace, directly over escape pipe, be provided with exhaust column, escape pipe and the independent structure of exhaust column for separating, the exhausting mouth of pipe bore of exhaust column is greater than the mouth of pipe bore of giving vent to anger of escape pipe, the exhausting mouth of pipe apart from the height of shaft greater than the height of the mouth of pipe of giving vent to anger apart from shaft.The structure that adopts this escape pipe and exhaust column to separate, can better avoid when being used when the wind-force of exhausting is bigger than normal, the inner heat that divides of sintering furnace chamber being taken away the labile state that causes inner thermal field because of pipeline directly is connected, thereby reach the stabilizing effect that increases in the sintering furnace cavity, the qualification rate of improving the quality of products.
As preferably, exhaust column is the hood-like structures of loudspeaker.
As preferably, the exhausting mouth of pipe that separates is about 9～11cm with the vertical range of the mouth of pipe of giving vent to anger.
As preferably, the bore sectional area of the exhausting mouth of pipe of exhaust column is about 3 times of the mouth of pipe of giving vent to anger.
The beneficial effects of the utility model are: change the escape pipe that is set to the sintering furnace shaft by the exhaust column structure of sintering furnace and be adopted as the independent frame mode that separates with exhaust column, can better avoid when the wind-force of exhausting is bigger than normal, the inner heat that divides of sintering furnace chamber being taken away the labile state that causes inner thermal field, thereby reach the effect of the stability that increases in the sintering furnace cavity, the qualification rate of improving the quality of products because of pipeline directly is connected.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model sintering furnace exhausting structure
The specific embodiment
Among the embodiment shown in Figure 1, the exhausting structure of sintering furnace, comprise shaft (30), exhaust column, the exhaust column outlet (12) of sintering furnace, shaft (30) is provided with the escape pipe (20) of sintering furnace, directly over escape pipe (20), be provided with exhaust column (10), both structures of escape pipe (20) and exhaust column (10) for separating, the exhausting mouth of pipe (11) bore of exhaust column (10) is greater than the mouth of pipe of giving vent to anger (21) bore of escape pipe (20), the exhausting mouth of pipe (11) apart from the height of shaft (30) greater than the height of the mouth of pipe of giving vent to anger (21) apart from shaft (30); Exhaust column (10) is the hood-like structures of loudspeaker, and escape pipe (20) is used in the extractor fan of sintering furnace (30) with exhaust column (10); The exhausting mouth of pipe (11) is about 9～11CM with the vertical range that the mouth of pipe of giving vent to anger (21) separates, and the sectional area of the exhausting mouth of pipe (11) of exhaust column is about 3 times of the mouth of pipe of giving vent to anger (21).Obtain the stability of thermal field in better exhausting effect and the sintering furnace cavity.
In the sintering course of work of sintering furnace, when the exhausting wind-force on the exhaust column is bigger than normal, because the function influence of negative pressure, the air of taking away exhausting mouth of pipe below flows to and has avoided the most of heat of the religion in the sintering furnace cavity is taken away, increased the thermal field stability in the sintering furnace cavity, the qualification rate of improving the quality of products.
