Description
The technical field is as follows:
the utility model relates to a single crystal growing furnace tears clear technical field open especially relates to an oxide cleaning device for draft tube lifting bar ring channel.
Background art:
monocrystalline silicon is a good semiconductor material, the purity requirement of the monocrystalline silicon reaches 99.9999 percent, even more than 99.9999999 percent, and the monocrystalline silicon is generally formed by drawing high-purity polycrystalline silicon in a monocrystalline furnace, because the purity requirement of the monocrystalline silicon is extremely high, after the monocrystalline furnace draws a furnace monocrystal, the success of drawing the next furnace monocrystal can be ensured without completely cleaning the furnace, in the process of cleaning the furnace, the yellowish oxidized powder of each thermal field component in the furnace must be cleaned (because the temperature in the monocrystalline furnace is over 1000 ℃ in the process of drawing the monocrystal, a layer of thin oxidized powder can be generated on the surface of the thermal field component, and the oxidized powder is generally removed by wiping the surface of the thermal field component by dipping alcohol by using fiber paper), and the oxide in a guide cylinder lifting system is difficult to clean, as shown in fig. 4: the oxidized powder generated in the annular groove 9 formed between the spherical cover 8 and the guide cylinder lifting rod 10 is difficult to remove, due to the limitation of the operation space and the special shape of the annular groove 9, in the prior art, the disassembling operator is generally wiped by winding the fiber paper absorbing alcohol at the tail end of the thin rod, during wiping, the operator needs to rotate around the guide cylinder lifting rod 10 for wiping, the wiping is extremely difficult, the working efficiency is low, the phenomenon that the oxidized powder is not wiped completely can occur, and the normal drawing of the monocrystalline silicon is influenced.
The utility model has the following contents:
an object of the utility model is to provide an oxide cleaning device for draft tube lifting bar ring channel.
The content of the utility model is as follows: an oxide cleaning device for an annular groove of a guide cylinder lifting rod comprises two semi-cylindrical cylinders which are hinged with each other, when the two cylinder bodies rotate around the hinge point, the two cylinder bodies can be completely buckled together to form a cylinder shape, the cylinder bodies sequentially comprise a lower half cylinder body and an upper half cylinder body which are concentrically arranged from bottom to top, the outer diameter of the lower semi-cylinder body is larger than that of the upper semi-cylinder body, the inner diameter of the lower semi-cylinder body is the same as that of the upper semi-cylinder body, the outer circumference of the upper semi-cylinder is provided with a plurality of threaded blind holes, the outer circumference of the upper semi-cylinder is covered with a plurality of layers of cleaning fiber paper or cleaning sponge, the cleaning fiber paper or the cleaning sponge is screwed with the threaded blind hole, and a handle is fixedly mounted on the outer circumferential surface of the lower semi-cylinder.
Furthermore, a guide angle is arranged on the outer edge of the top end of the upper semi-cylinder body.
The utility model has the advantages that: the utility model discloses simple structure, design two semi-cylindrical barrels of mutual articulated, during the use single hand hold down semi-cylindrical body and insert the finger in the handle control the barrel open and close, when cleaning the annular groove, only need open semi-cylindrical body then with draft tube lifting bar lock in the barrel, hold the fiber paper position that the barrel will dip in the alcohol and insert the annular groove in clean from top to bottom can, not only clean thoroughly, clean convenient and fast moreover, time saving and labor saving, work efficiency is high.
Description of the drawings:
fig. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a perspective view of the barrel of the present invention;
fig. 3 is a top view of the present invention;
FIG. 4 is a schematic structural view of the part of the utility model needing to be cleaned;
in the figure, a cylinder body 1, a lower semi-cylinder body 1-2, an upper semi-cylinder body 1-3, a threaded blind hole 3, cleaning fiber paper or cleaning sponge 4, a locking screw 5, a handle 6, a guide angle 7, a spherical cover 8, an annular groove 9 and a guide cylinder lifting rod 10.
The specific implementation mode is as follows:
as shown in fig. 1 to 3, an oxide cleaning device for an annular groove of a guide cylinder lifting rod comprises two semi-cylindrical barrels 1 hinged to each other, wherein the two barrels 1 can be completely buckled together to form a cylinder when rotating around a hinge point, the barrels 1 sequentially comprise a lower semi-cylindrical body 1-2 and an upper semi-cylindrical body 1-3 concentrically arranged from bottom to top, the outer diameter of the lower semi-cylindrical body 1-2 is larger than the outer diameter of the upper semi-cylindrical body 1-3, the inner diameter of the lower semi-cylindrical body 1-2 is the same as the inner diameter of the upper semi-cylindrical body 1-3, a plurality of threaded blind holes 3 are formed in the outer circumferential surface of the upper semi-cylindrical body 1-3, a plurality of layers of cleaning fiber paper or cleaning sponge 4 are covered on the outer circumferential surface of the upper semi-cylindrical body 1-3, and a locking screw 5 is further included, the locking screw 5 penetrates through the cleaning fiber paper or the cleaning sponge 4 to be in threaded connection with the threaded blind hole 3, and a handle 6 is fixedly arranged on the outer circumferential surface of the lower semi-cylinder body 1-2; and a guide angle 7 is arranged at the outer edge of the top end of the upper semi-cylinder body 1-3.
The working principle is as follows: during operation, lower semicircular cylinder 1-2 and first semicircular cylinder 1-3 are opened, make its lock on draft tube lifting bar 10, then handheld handle 6 rises the utility model discloses make first semicircular cylinder 1-3 clean fiber paper or clean sponge 4 position enter into annular groove 9, rotatory clean can.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
