Description
Technical field
The present invention relates to the cutting waste mortar that the silicon chip cutting produces in the solar energy industry and reclaim the field again, relate in particular to a kind of employed waste material acid dip pickle of technological process that from silicon chip dicing waste mortar, reclaims silicon carbide micro-powder.
Background technology
" waste mortar recycling project " results from the manufacture process of solar cell.Especially in recent years the develop rapidly of silicon solar cell makes " waste mortar recycling project " also obtain very big expanding space.In silicon solar cell was produced, silicon chip manufacturing (silicon rod cutting) operation can produce a large amount of " waste mortars ", " useless cutting liquid " and part " waste silicon powder ", and we can be referred to as them and be " waste mortar ".These " waste mortars " are handled through processing, can will wherein there be " silicon carbide micro-powder ", " the cutting liquid " and " silica flour " of high using value to extract, can produce very high economic benefit and social benefit, the service field of this project that Here it is and generation origin.
Current, the multifibres cutting machine (abbreviating " scroll saw " or " wire cutting machine " as) of free abrasive particle is all adopted in the silicon rod cutting, it is cutting silk (steel wire) fast moving on silicon rod by many diameter 0.12 millimeter of sheave traction, and by the grinding of " diamond dust " and " cutting liquid ", carry, acting in conjunction such as cooling, it is hundreds of sheet even several thousand equidimension silicon chips of 0.12～0.20 millimeter that 6～12 inches polycrystalline silicon rods of diameter are once cut into thickness.In the cutting process of " wire cutting machine ", can use a large amount of " cutting liquid " and " carborundum ", and mixed in together with the silicon rod fine powder (silica flour) that cuts, formed a large amount of " waste mortar "." waste mortar " that all silicon chip cutting producers of the annual whole nation produce has the hundreds of thousands ton, and the disposal ability of " waste mortar " recycling producer is limited, make quite a few " waste mortar " can not get dealing carefully with, cause the wasting of resources and environmental pollution, be much to be regretted." waste mortar recycling project " is a project that development prospect is very good." the low carbonization " of world environments and the anxiety of the energy promote the development rapidly of solar cell (photovoltaic) industry, thereby have opened up the vast market space for this project that the annual value of production in this space has hundred million yuans of hundreds ofs.Worldwide " low-carbon (LC) " reduces discharging the anxiety of motion and the energy, impels people to develop clean new forms of energy, and solar cell (photovoltaic) is undoubtedly our best choice.Catching this good market opportunity, all will be a quite significant thing to individual economy and social environment.It is with Separation of Solid and Liquid that present waste mortar reclaims common treatment again, solid waste is and reclaims the raw material that comprises silicon carbide micro-powder again, then solid waste is carried out slurrying, alkali cleaning, pickling, rinsing, oven dry etc. step and obtain the higher silicon carbide micro-powder of purity, but often can not effectively be removed owing to the insufficient impurity that causes of pickling at acid cleaning process, thereby be reduced the carborundum purity that obtains.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of silicon carbide micro-powder that can realize abundant pickling recovered acid cleaning device again, can effectively improve the recovery purity of carborundum in the silicon chip dicing waste mortar, improve organic efficiency.
For achieving the above object, the present invention proposes following technical scheme:
A kind ofly reclaim the agitating device of technology again for silicon carbide micro-powder, this acid dip pickle comprises agitator, acid wash drum; Described agitator comprises stirring rod, and described stirring rod one end is fixedlyed connected with runner, and the other end extends to described acid wash drum bottom; Described runner is installed on the panel, and links to each other with motor by belt, on the described motor installation panel; The described stirring rod other end also is provided with the paddle of two groups of horizontal positioned; Described panel is fixed on the acid wash drum, and described stirring rod is positioned at the central shaft position.
Further, the projection of two groups of paddle horizontal planes is vertical mutually, and one group of paddle position is higher than another group paddle.
Further, paddle is dull and stereotyped blade, and the number of every group of paddle is two, and two paddles, 45 degree of turning back on the contrary.
Further, the acid wash drum bottom is polygon, and such as hexagon, when paddle stirred the drive liquid in rotation, acid wash drum bottom polygonized structure can be anti-with bigger obstruction power, thereby make stirring more even.
Beneficial effect: (1) agitator provided by the invention, stir at acid wash drum automatically, effectively reduce manually-operated, the inhomogeneous alkali cleaning that causes of the stirring of avoiding manually-operated to bring is insufficient, increases work efficiency; (2) stirring rod of the present invention is provided with two groups of paddles so that in fully stir; (3) acid wash drum bottom interior wall of the present invention is hexagon, so that stir.
Description of drawings
Fig. 1 is agitator structure schematic diagram of the present invention.
Fig. 2 is the structural representation of the stirring rod of the present invention's employing.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
The present invention proposes a kind ofly reclaims the agitating device of technology again for silicon carbide micro-powder, comprises agitator, acid wash drum; As shown in Figure 1, agitator comprises stirring rod (1), and stirring rod (1) one end is fixedlyed connected with runner (2), and the other end extends to described acid wash drum bottom; Runner (2) is installed on the panel (3), and links to each other with motor (5) by belt (4), on motor (5) installation panel (3); Stirring rod (1) other end also is provided with the paddle of two groups of horizontal positioned.
Panel (3) is fixed on the acid wash drum, and described stirring rod (5) is positioned at the central shaft position.In addition, the acid wash drum bottom is polygon, and such as hexagon, when paddle stirred the drive liquid in rotation, acid wash drum bottom polygonized structure can be anti-with bigger obstruction power, thereby make stirring more even.
As shown in Figure 2, stirring rod is provided with two groups of paddles.The projection of two groups of paddle horizontal planes is vertical mutually, and one group of paddle position is higher than another group paddle.Paddle is dull and stereotyped blade, and the number of every group of paddle is two, and two paddles, 45 degree of turning back on the contrary.
Silicon carbide micro-powder reclaims in the process treatment process, slurry after the alkali cleaning is got to acid wash drum, agitator motor (5) drives runner (2) rotation, stirs thereby drive stirring rod (1), and stir speed (S.S.) is controlled by motor (5) fully, stirring fully, adding sulfuric acid in back carries out pickling, thereby finish the processing step of pickling, whole process is simply efficient, effectively raises operating efficiency, also make alkali cleaning more abundant, the silicon carbide micro-powder purity that obtains is higher.
The above only is preferred embodiment of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
