Abstract
The utility model discloses a kind of air curtain structure for solar cell sintered furnace, comprise upper cavity and the lower chamber of hollow, the upper surface of described upper cavity and the lower surface of described lower chamber are provided with blow vent, the lower surface of described upper cavity and the upper surface of described lower chamber are provided with corresponding aperture uniformly, wherein, the upper surface of described lower chamber is inclined-plane, and the upper surface inclined-plane low edge of described lower chamber is domaticly connected with waste material box by one.After the utility model compressed air passes into, distribute first again in upper and lower inside cavity, then enter uniformly in body of heater along aperture, ensure to enter the compressed-air actuated uniformity in body of heater; By the inclined-plane of lower chamber upper surface, can make foreign matter landing on inclined-plane of generation in body of heater, reduce the compressed air skewness causing due to foreign matters from being blocked aperture; And can be further by foreign matter collection in the waste material box being connected compared with low edge with inclined-plane, foreign matter is cleared up outward at body of heater, avoids safeguarding blow-on body at every turn, shortens maintenance time.
Description
Technical field
The utility model relates to a kind of sintering furnace, is specifically related to a kind of air curtain structure of sintering furnace.
Background technology
An important step in making as crystal silicon cell, the sintering circuit of solar cell is, by high temperature, the silver slurry, the aluminium paste that are printed onto silicon chip surface are carried out to sintering, make it with the electrode that forms Ohmic contact between silicon chip and then form solar cell, the electric weight that solar cell is produced can be derived.
In sintering circuit, sintering furnace generally heats by infrared lamp, passes into compressed air simultaneously, and the temperature in the single warm area of body of heater can be uniformly distributed, and therefore the control of air-flow has direct impact to the quality of solar cell sintering effect.General air-flow control adopts and directly the mode of blowing is passed into compressed air up and down, and compressed-air actuated skewness, easily causes the inhomogeneous of temperature.Simultaneously along with the increase of running time, lower outlet is because the wearing and tearing in fragment or sintering furnace furnace zone can cause part foreign matters from being blocked gas outlet, and then affects the atmosphere in whole body of heater.Because body of heater is airtight, in the time that compressed-air actuated lower outlet is blocked, cannot directly find from appearance, be easy to cause the bad phenomenon of property in batches, so original air curtain structure needs further to optimize and improve.
Utility model content
Utility model object: the purpose of this utility model is for the deficiencies in the prior art, and a kind of air curtain structure for solar cell sintered furnace of ventilating evenly and effectively preventing foreign matters from being blocked is provided.
Technical scheme: a kind of air curtain structure for solar cell sintered furnace, comprise upper cavity and the lower chamber of hollow, the upper surface of described upper cavity and the lower surface of described lower chamber are provided with blow vent, the lower surface of described upper cavity and the upper surface of described lower chamber are provided with corresponding aperture uniformly, wherein, the upper surface of described lower chamber is inclined-plane.The lower surface blow vent of the upper surface of upper cavity and lower chamber connects compressed air, after compressed air passes into, enters uniformly in the body of heater between upper and lower cavity along aperture, ensures to enter the compressed-air actuated uniformity in body of heater; By the ramp structure of lower chamber upper surface, can make the foreign matter producing in body of heater by inclined-plane landing, reduce the compressed air skewness causing due to foreign matters from being blocked aperture.
Further, the upper surface inclined-plane low edge of described lower chamber is domaticly connected with waste material box by one, can, by the domatic waste material box that enters, be easy to foreign matter to clear up at body of heater outward from the foreign matter of inclined-plane landing, avoids safeguarding blow-on body at every turn, shortening maintenance time.
Preferably, the distance between described upper cavity and lower chamber is 10cm, and this distance can either ensure that the furnace zone of carrying cell piece passes through smoothly, makes again whole space length little, and heat is more easily concentrated, the energy resource consumption when reducing heating and safeguarding temperature.
Preferably, the diameter of the aperture on described upper cavity and lower chamber is 0.2mm, and the spacing between adjacent aperture is 0.5mm, adopts this kind of aperture distribution mode can ensure gas evenly convection current between upper and lower cavity.
Further, described upper cavity and lower chamber are made up of stainless steel, can avoid it under hot environment, to be out of shape for a long time.
Beneficial effect: distribute first again in upper and lower inside cavity after the utility model compressed air passes into, then enter uniformly in body of heater along aperture, ensure to enter the compressed-air actuated uniformity in body of heater; By the inclined-plane of lower chamber upper surface, can make foreign matter landing on inclined-plane of generation in body of heater, reduce the compressed air skewness causing due to foreign matters from being blocked aperture; And can be further by foreign matter collection in the waste material box being connected compared with low edge with inclined-plane, foreign matter is cleared up outward at body of heater, avoids safeguarding blow-on body at every turn, shortens maintenance time.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
embodiment: a kind of air curtain structure for solar cell sintered furnace, as shown in Figure 1, comprise upper cavity 1, lower chamber 2 and the waste material box 3 of hollow, upper cavity 1 is cuboid, the lower surface of the upper surface of upper cavity 1 and lower chamber 2 is respectively equipped with blow vent 4 for passing into compressed air, and the upper surface of the lower surface of upper cavity 1 and lower chamber 2 is provided with corresponding aperture 5 uniformly, wherein, the upper surface of lower chamber 2 is inclined-plane, and inclined-plane low edge is domaticly connected with waste material box 3 by one.
In the time that cell piece passes through sintering furnace body, upper cavity 1 upper surface and lower chamber 2 lower surfaces in air curtain structure pass into compressed air by blow vent 4 simultaneously, entering in the furnace space between upper and lower cavity by aperture 5 even structure after compressed air distributes in upper and lower cavity again.In the time having fragment or foreign matter to drop, by the upper surface inclined-plane of lower chamber 2, foreign matter moves to the lower, and finally drops in the waste material box 3 being connected with lower chamber 2.Compared with prior art, by the design of upper and lower two cavitys, compressed air is carried out distributing again, and by uniform aperture 5 structures, can realize compressed air being uniformly distributed in body of heater.Meanwhile, in foreign matter drops body of heater time, foreign matter is easy to drop in waste material box 3, avoids foreign matters from being blocked aperture 5 to cause compressed air skewness.
As mentioned above, although represented and explained the utility model with reference to specific preferred embodiment, it shall not be construed as the restriction to the utility model self.Not departing under the spirit and scope prerequisite of the present utility model of claims definition, can make in the form and details various variations to it.
