Description
Technical field
The utility model relates to a kind of device cleaning seed crystal.
Background technology
In photovoltaic industry, square seed crystal, in cutting, fluting process, can produce certain mechanical stress on its surface, and these stress damages easily side's of making seed crystal exist fracture hidden danger in crystal pulling use procedure.Another aspect side's seed crystal is after pulling monocrystalline, and surface has oxidative phenomena in various degree, if unclear the washing away of these remaining impurity is removed, when next cycle uses, can bring in silicon liquid, and then introduces impurity, increase the probability of crystal pulling failure.So need the side's of carrying out seed crystal cleaning; current cleaning; each only cleaning square seed crystal; owing to cleaning at normal temperatures, chemical reaction slowly, the cleaning if many square seed crystals are put together; have contact surface less cleaning position between part side's seed crystal on the one hand; on the other hand in order to make reaction even, need constantly stir, certainly will the side's of increase seed crystal because of the possibility causing mechanical damage of mutually colliding with.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of device cleaning seed crystal, the features such as cost of manufacture is low, handling safety, cleaning efficiency are high, cleaning performance is good that it has.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Clean a device for seed crystal, comprise workbench, at the left end of workbench, pure water groove is installed, its right-hand member installs acid dip pickle, and acid dip pickle comprises installation water-bath on the table, and water-bath is provided with electric heater unit, descaling bath is set in water-bath, above descaling bath, is provided with gas skirt; The also side's of comprising seed crystal fixture, side's seed crystal fixture comprises the rectangular frame be made up of two Chang Liang and two short beams, two long beams are arranged with multipair side's seed crystal fixing hole, side seed crystal fixing hole and square seed crystal cross section suitable, the center line of every the other side's seed crystal fixing hole is parallel with short beam.
The utility model improves further and is:
Two long beams are arranged with eight the other side's seed crystal fixing holes.
The beneficial effect adopting technique scheme to produce is:
The utility model comprises workbench, at the left end of workbench, pure water groove is installed, its right-hand member installs acid dip pickle, acid dip pickle comprises installation water-bath on the table, water-bath is provided with electric heater unit, in water-bath, descaling bath is set, by the water-bath being provided with electric heater unit, the pickle in descaling bath is heated, homogeneous heating, because specific heat of water value is larger, pickle temperature is in cleaning process, larger fluctuation can not be produced because of the temperature difference of itself and environment and square seed crystal, keep cleaning temperature balanced to a certain extent, thus ensured cleaning quality, clean under normal temperature state, pickle concentration is low, solution is uneven with the reaction of silicon material, need to stir and extend scavenging period, stir and just easily cause colliding with of seed crystal, pickle (mixed acid of hydrofluoric acid and nitric acid) is more abundant with the reaction of silicon material in 50 degrees Celsius, more easily carry out, impurity and the damage layer on silicon material surface can be removed, need not stir by the other side's seed crystal in cleaning process, avoid the damage because mechanical collision causes, gas skirt is provided with above descaling bath, pernicious gas is siphoned away by gas skirt, avoids the health of its harm operating personnel, the also side's of comprising seed crystal fixture, side's seed crystal fixture comprises the rectangular frame be made up of two Chang Liang and two short beams, two long beams are arranged with multipair side's seed crystal fixing hole, side seed crystal fixing hole and square seed crystal cross section suitable, the center line of every the other side's seed crystal fixing hole is parallel with short beam when cleaning, by in multiple side's seed crystal sides of being arranged on seed crystal fixing hole, make its position relatively fixing, can once clean multiple side's seed crystal, improve operating efficiency, it also avoid the generation of collision simultaneously, it is low that the utility model has cost of manufacture, handling safety, cleaning efficiency is high, the features such as cleaning performance is good.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
From the embodiment shown in Fig. 1-4, the present embodiment comprises workbench 1, at the left end of workbench 1, pure water groove 2 is installed, its right-hand member installs acid dip pickle, acid dip pickle comprises the water-bath 3 be arranged on workbench 1, water-bath 3 is provided with electric heater unit, arranges descaling bath 4 in water-bath 3, is provided with gas skirt 5 above descaling bath 4; The also side's of comprising seed crystal fixture, side's seed crystal fixture comprises the rectangular frame be made up of two long beams 6 and two short beams 7, two long beams 6 are arranged with eight the other side's seed crystal fixing holes 8, side's seed crystal fixing hole 8 is suitable with square seed crystal 9 cross section, and the center line of every the other side's seed crystal fixing hole 8 is parallel with short beam 7.
Method of operating:
By in the square seed crystal side of being arranged on seed crystal fixture, and be placed in descaling bath 4 by lifting rope, by the water-bath being provided with electric heater unit, the pickle in descaling bath is heated, temperature controls between 40 degree of-50 degree, pickle can clean by the other side's seed crystal, after cleaning, square seed crystal fixture is taken out and puts into the cleaning of pure water groove again, can the cleaning of the side's of completing seed crystal.
