Abstract
The utility model discloses a hoisting hook of a czochralski (CZ) method graphite heat shield. The hoisting hook comprises connecting column, wherein the lower end of the connecting column is fixedly connected with a Y-shaped support, front ends of the Y-shaped support are respectively hinged with a supporting rod, and the bottom of each supporting rod is provided with a frame-shaped hook. The hoisting hook is simple in structure. By means of the movable hook structure, during a heat shield descending process, the hoisting hook ensures that the hook can fall off automatically when the heat shield descends to a position meeting requirements, stability and security of installation of the heat shield are ensured, smooth production of single crystals is ensured, throwing amount of a single furnace can be increased by 20 kilograms to 40 kilograms, and unit energy consumption can be lowered by 30 percent or so.
Description
Technical field
The utility model relates to the suspender field of lifting graphite heat shielding, specifically a kind of suspending hook of CZ vertical pulling method graphite heat shielding.
Background technology
Careless photovoltaic application strengthens, and more and more people find how the photovoltaic generation cost becomes the large bottleneck that serious restriction photovoltaic generation is applied.For the workout cost problem, more and more new technology begins to be applied in the industry, improves each manufacturing process of solar cell, and raw materials cost is down to 20 U.S. dollars by 400 U.S. dollars in 2007; Technique for processing silicon chip is down to 180um by original 230um; Solar battery sheet manufacture craft photoelectric transformation efficiency is by 12%, is improved to present 18% etc.The utilization of a large amount of new technologies, effect are significant, and the photovoltaic generation cost is reduced to 0.88 yuan of kw.h in 2011 by the kw.h of RMB5.5 unit in 07 year, greatly reduces cost of electricity-generating, becomes possibility so that large-scale photovoltaic generation is used.
Original graphite field design feeds intake after the end, and the graphite heat shielding directly is placed on to heat on the heat shielding supporting disk carries out monocrystalline production.Because heat shielding is to the limited space of quartz crucible bottom, the charging capacity of general 20 cun thermal fields only is about 80-90kg, how to reduce product energy consumption in process of production, and reducing the unit tooling cost is to reduce the key of comprehensive electric generating cost.
The utility model content
The purpose of this utility model provides a kind of suspending hook of CZ vertical pulling method graphite heat shielding, is improved for the Lift-on/Lift-off System of graphite heat shielding, further reduces the power consumption of polymer processing of solar level silicon single crystal rod.
The technical solution of the utility model is as follows:
A kind of suspending hook of CZ vertical pulling method graphite heat shielding includes joint pin, it is characterized in that: the lower end of described joint pin is fixedly connected with Y type support, and the front end of described Y type support is hinged with respectively pole, and the bottom of described pole has the frame hook.
The suspending hook of described CZ vertical pulling method graphite heat shielding, it is characterized in that: hang on the seed crystal flexible axle upper end of described joint pin.
The suspending hook of described CZ vertical pulling method graphite heat shielding is characterized in that: the front end of described Y type support is hinged with pole by the molybdenum screw rod respectively.
The suspending hook of described CZ vertical pulling method graphite heat shielding is characterized in that: described frame hook connecting is connected on the bayonet socket place on the graphite heat shielding.
The beneficial effects of the utility model:
Of the present utility model simple in structure, adopt flexible hook structure, in reducing the heat shielding process, after guaranteeing that heat shielding is reduced to till the requirement, the hook Automatic-falling can guarantee stability and security that heat shielding is installed, can guarantee carrying out smoothly of monocrystalline production, the utility model can increase single stove charging capacity 20-40kg, and unit consumption of energy can reduce about 30%.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of suspending hook of CZ vertical pulling method graphite heat shielding includes joint pin 1, and the lower end of joint pin 1 is fixedly connected with Y type support 2, and the front end of Y type support 2 is hinged with respectively pole 3, and the bottom of pole 3 has frame hook 4.
In the utility model, joint pin 1, Y type support 2, pole 3 all adopt the 316L stainless steel to be processed into, and hang on the seed crystal flexible axle upper end of joint pin 1; The front end of Y type support 2 is hinged with pole 3 by metal screw 5 respectively, so that pole 3 can upper and lower activity on Y type support 2, its activity point of view is 0-90 °; The frame hook 4 bayonet socket places that are connected on the graphite heat shielding.
The utility model is by the seed crystal flexible axle on the single crystal growing furnace, the height between the 100mm-170mm so that the graphite heat shielding is upwards sling has increased the space that feeds intake, the maximum 110-120kg that can feed intake, reaching charging capacity increases by 30% purpose, correspondingly can directly reduce crystal bar unit consumption of energy about 30%.
