Description
Technical field
The utility model relates to single crystal furnace device technical field, a kind of secondary charging for single crystal growing furnace
Funnel device.
Background technology
Metallurgy industry single crystal growing furnace is the necessary equipment that polysilicon is converted in monocrystalline silicon technical process, and monocrystalline silicon
Being again the basic material in photovoltaic generation and semicon industry, monocrystalline silicon props up as the key of advanced information society
Timbering material, is one of the most most important current monocrystal material, and it is not only development computer and integrated electricity
The major function material on road, is also the photovoltaic generation major function material that utilizes solar energy；Single crystal growing furnace is at silicon list
After crystalline substance has drawn, secondary charging device is used can again to put into particulate Si material in silica crucible, it is achieved
The recycling of silica crucible, reduces the drawing time of second silicon rod；General secondary charging device for single crystal furnace,
All be use fastening mode realize, crystal bar pulling process feeds less, crucible utilization rate low, its knot
Structure is dumb, does not has regulatory function, easily causes the phenomenons such as pull bar when feeding intake blocks.
Summary of the invention
The utility model technical issues that need to address are to make material by circular platform type baffle plate and rotary lifting mechanism
More scattered drop in crucible, improve the utilization rate of crucible inner space；There is provided one for monocrystalline
The secondary charging funnel device of stove.
For solving above-mentioned technical problem, structure of the present utility model include single crystal furnace body, end cap, funnel,
Crucible, pull bar, baffle plate and rotary lifting mechanism, described funnel and crucible be positioned at single crystal furnace body, institute
The end cap stated is connected to the top of single crystal furnace body, and described pull bar passes vertically through funnel, under described pull bar
End is connected with baffle plate, and the upper end of described pull bar is connected with rotary lifting mechanism, and described funnel is solid by flange
Surely it is connected in single crystal furnace body, the end that described crucible is fixedly connected in single crystal furnace body by electronic thick stick
Portion.
Further: described rotary lifting mechanism includes that motor, cylinder and shaft coupling, described motor pass through
Shaft coupling is connected with pull bar, and described cylinder is connected to the top of motor.
Further: described baffle plate is circular platform type baffle plate, the size of described circular platform type baffle plate upper end and funnel
The size of discharging opening matches.
After using said structure, the utility model makes material more by circular platform type baffle plate and rotary lifting mechanism
Scattered drop in crucible, improve the utilization rate of crucible inner space；And the design also has structure
Simply, the easily fabricated and advantage of practicality and high efficiency.
Accompanying drawing explanation
With detailed description of the invention, the utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of secondary charging funnel device for single crystal growing furnace as shown in Figure 1, including single crystal furnace body 1, end
Lid 2, funnel 3, crucible 5, pull bar 6, baffle plate 7 and rotary lifting mechanism, described funnel 3 and crucible 5
Being positioned at single crystal furnace body 1, described end cap 2 is connected to the top of single crystal furnace body 1, described pull bar 6
Passing vertically through funnel 3, the lower end of described pull bar 6 is connected with baffle plate 7, and the upper end of described pull bar 6 rises with rotating
Descending mechanism is connected, and described funnel 3 is fixedly connected in single crystal furnace body 1 by flange 4, described earthenware
Crucible 5 is fixedly connected on the bottom in single crystal furnace body 1 by electronic thick stick 8.During work, first raw material is poured into
In funnel 3, then start rotary lifting mechanism and make pull bar 6 move downward, make baffle plate 7 at the work of pull bar 6
Being separated with the lower discharging opening with funnel 3, the raw material in funnel 3 can be automatically from funnel 3 in the effect of gravity
The discharging opening of bottom drops out, and drops after crucible 5, and the raw material of a portion can drop on baffle plate 7,
Now rotary lifting mechanism is rotated with baffle plate 7 by pull bar 6, and the raw material of this part is at baffle plate 7
Effect is lower can be diffused to surrounding, thus more scattered drops in crucible, serves in raising crucible
The effect of portion's space availability ratio.During raw material drops, start electronic thick stick 8, make electronic thick stick 8 with crucible
5 progressively move downward, so that raw material can fill up whole crucible 5 more quickly, the design has structure
Simply, the easily fabricated and advantage of practicality and high efficiency.
Rotary lifting mechanism as shown in Figure 1 includes motor 10, cylinder 9 and shaft coupling 11, described motor
10 are connected with pull bar 6 by shaft coupling 11, and described cylinder 9 is connected to the top of motor 10.During work
When needs make raw material automatically drop, startup cylinder 9 is passed to pull bar 6 and transports downwards with baffle plate 7
Dynamic, make baffle plate 7 be separated with the discharging opening of funnel 3.When raw material is diffused by needs, start motor
10 are passed to pull bar 6 rotates with baffle plate 7, so that the material dropped on baffle plate 7 is centrifugal
Carry out dispersion from trend surrounding under the effect of power to drop.
Baffle plate 7 as shown in Figure 1 is circular platform type baffle plate, the size of described circular platform type baffle plate upper end and funnel 3
The size of discharging opening matches.The utility model design by circular platform type baffle plate, makes raw material keep off at circular platform type
Disperse from trend surrounding under the effect of plate, improve the utilization rate of crucible inner space.
