Description
Technical field
The utility model relates to a kind of drier, relates in particular to a kind of centrifugal force that utilizes and is used for the drier that solar silicon wafers is dried.
Background technology
Solar energy is widely used as a kind of clean energy resource just day by day.Silicon chip is an of paramount importance element in the solar energy industry, and silicon chip needs through the multiple tracks treatment process in production procedure, so that guarantee the photoelectric conversion result and the light utilization efficiency of silicon chip.Making herbs into wool to silicon chip surface is exactly a kind of effective measures that improve the silicon chip light utilization efficiency, and the making herbs into wool operation of silicon chip surface is to utilize the mixed solution of nitric acid and hydrofluoric acid that silicon chip surface is carried out etching, to increase the area of silicon chip surface.Silicon chip through after the etching also need be immersed in tank, alkali groove, the tank successively.After silicon chip making herbs into wool finishes, need make silicon chip surface dry, so that silicon chip is carried out the next procedure operation.Realize the drying of silicon chip surface, current way is to utilize centrifugal drier that silicon chip is dried.Because drier and etching device spatially need have certain interval; Transporting silicon chip to the drier position from etching device, and needing certain time interval after being placed in the drier, if the work of drier joint gathers the work joint that does not catch up with etching device and gathers to silicon chip; Cause leaving the silicon chip of waiting for drying in the drier outside; The described time interval can be longer, and in this time interval, some silicon chip surfaces are local can natural air drying.Though in carrying out the making herbs into wool process; Silicon chip need enter into tank twice and soak; But silicon chip surface still can residual number acid or alkali impurity, if under the air-dry situation of silicon chip surface, formed current were taken away when these impurity can not be dried; Still can remain on the silicon chip surface, thereby have influence on the photoelectric transformation efficiency of silicon chip.Therefore, existing common drier can bring some influences to the quality of silicon chip.
The utility model content
For overcoming above-mentioned defective, the purpose of the utility model is: a kind of solar silicon wafers drier is provided, and it can effectively improve the cleannes of silicon chip surface, thereby improves the photoelectric transformation efficiency of solar energy.
In order to solve the technical problem the technical scheme of the utility model: the solar silicon wafers drier comprises housing and loam cake; Have cavity in the housing, be provided with rotating disk, have the gap between rotating disk and the cavity inner wall in the bottom of cavity; Rotating disk is provided with the plurality of fixed frame, and movable connection the between loam cake and the housing, loam cake can cover the oral area of cavity; On upper interior surface, be provided with standpipe towards said cavity; Standpipe links to each other with water pump, and the length that standpipe is projected into the upper interior surface Outboard Sections is slightly less than the degree of depth of cavity, and standpipe is provided with some spouts that communicate with its inside.Standpipe is used for communicating with water pump, carrying out the drying initial stage, through water pump to standpipe pump water, thereby make silicon chip surface drenched.
On standpipe, be provided with the nozzle consistent with the spout number, each nozzle is located at a nozzle exit area place.
Inside at loam cake is provided with heater.
Said loam cake and housing are hinged, and between loam cake and housing, are provided with elevating mechanism, and elevating mechanism and upper interior surface are hinged.
Said fixed mount comprises support that is the dustpan shape and the fixed bar that takes the shape of the letter U, and support is a loose structure, and the edge that the openend of fixed bar passes support is fixed on the rotating disk.
The beneficial effect of the utility model: owing on upper interior surface, be provided with standpipe, and standpipe is provided with some spouts that communicate with its inside, and to standpipe pump water, water sprays in spout through water pump, thereby silicon chip surface is drenched.When drier dries operation, can form current everywhere at silicon chip surface, current can sweep along silicon chip surface everywhere most impurity and be thrown out of, thereby can imitate the cleannes that improve silicon chip surface, improve the photoelectric transformation efficiency of silicon chip.
Description of drawings
Fig. 1 is the structural representation of this solar silicon wafers drier under the loam cake open mode.
The specific embodiment
The structure of this solar silicon wafers drier comprises housing 7 and loam cake 1, is provided with cylindrical cavity 4 in the housing 7, and loam cake 1 can cover the oral area of cavity 4.Be hinged together through loose-leaf 9 between loam cake 1 and the housing 7, on loam cake 1 inner surface, be provided with Gask-O-Seal 2, after loam cake 1 overlayed on the housing 7, this Gask-O-Seal 2 snapped onto the mouth position place of cavity 4.
Be provided with rotating disk 6 in the bottom of cavity 4, have the gap between rotating disk 6 and cavity 4 inwalls, rotating disk 6 is connected with motor, under the drive of motor, rotating disk 6 can be in cavity 4 high speed rotating.
Rotating disk 6 is provided with a plurality of fixed mounts, and fixed mount is used to place the loading frame that is mounted with the multi-disc silicon chip, and the footpath that the center line of fixed mount is positioned at rotating disk 6 makes progress.Fixed mount comprises support 8 and fixed bar 5; Support 8 is the dustpan shape, and support 8 is a loose structure, and each fixed mount is corresponding to two fixed bars 5; Fixed bar 5 takes the shape of the letter U; The openend of fixed bar 5 passes the edge of support 8, and is fixed on the rotating disk 6, and two fixed bars 5 are positioned at the position, relative both sides of support 8.After loading frame was placed on the fixed mount, loading frame can have good stability.
Center position at loam cake 1 inner surface is provided with a standpipe 11, and standpipe 11 links to each other with water pump.Standpipe 11 is towards described cavity 4, and standpipe 11 is projected into the degree of depth of the length outline of loam cake 1 inner surface Outboard Sections less than cavity 4.When loam cake 1 covered cavity 4 oral areas, standpipe 11 was plugged in the cavity 4.On standpipe 11, be provided with some spouts, spout communicates with the inside of standpipe 11.The position of each spout is provided with a nozzle 10 on standpipe 11, and these nozzles 10 are arranged in the certain length range of standpipe 11, so that from the differing heights direction silicon chip is sprayed.
For quickening the rate of drying of silicon chip, in loam cake 1 set inside the electrothermal tube heater is arranged, so that drier is carrying out being used for the heating to silicon chip in the drying process to silicon chip, improve the dry speed of silicon chip surface.
Owing in loam cake 1, be provided with heater, the thickness of loam cake 1 is also thicker relatively, and this makes loam cake 1 have certain weight.For ease of raising loam cake 1, between housing 7 and loam cake 1, be provided with elevating mechanism 3, this elevating mechanism 3 can hydraulic cylinder or cylinder, and this elevating mechanism 3 is hinged together with loam cake 1 inner surface.
After having placed loading frame on the fixed mount and having covered loam cake 1, water pump starts in advance, makes nozzle 10 be the silicon chip water spray; And then rotating disk 6 is started, nozzle 10 stops the operation of spraying water after spraying certain hour for silicon chip; Before rotating disk 6 starts or meanwhile, heater is started working, under action of centrifugal force; And under the effect of heating of heater, silicon chip surface can be realized drying very soon.
