Description

Technical Field

[0001] The utility model belongs to the technical field of glass heating, and particularly relates to a device for removing SiC sleeves of a cover glass muffle furnace. Background Art

[0002] The SiC sleeve is an extremely important protection device in the heating of the threaded rod of the muffle furnace. It has excellent thermal shock resistance, high thermal conductivity, and corrosion resistance, and can effectively protect the threaded rod. Volatiles will be generated during the production of glass in the muffle furnace. During the process of replacing the SiC sleeve in the muffle furnace, the local temperature in the muffle furnace will decrease, resulting in an increase in the viscosity of the volatiles deposited between the surface of the SiC sleeve and the furnace body. In addition, due to the high temperature of the muffle furnace in glass production, operators need to wear thick fireproof and high-temperature-resistant clothes and gloves to pull out the SiC sleeve. It is difficult to exert force, there is a certain danger, the operation time is long, and it affects the process recovery time. Content of the Utility Model

[0037] The embodiments of the present utility model provide a device for removing the SiC sleeve of a cover glass muffle furnace, including a connecting piece 3. The connecting piece 3 is a tubular structure, and its outer diameter is smaller than the inner diameter of the SiC sleeve 8. A support piece 6 is provided at the end of the connecting piece 3, and the connecting piece 3 is internally connected with the support piece 6; a stretching assembly is installed inside the connecting piece 3, one end of which extends into the inside of the connecting piece 3 and extends out from the end of the support piece 6 to be connected with the top block 7, and the other end is located outside the connecting piece 3 away from the end of the support piece 6; a pulling piece 4 and a clamping piece 5 are installed outside the connecting piece 3, and the clamping piece 5 is used to abut against the top of the SiC sleeve 8 so that the pulling piece 4 can remove the SiC sleeve 8. As Figure 1 and Figure 4 shown, before removing the SiC sleeve 8, first manually insert the connecting piece 3 into the SiC sleeve 8, manually rotate the clamping piece 5 so that the clamping piece 5 abuts against the top of the SiC sleeve 8, then manually rotate the stretching assembly, and the top block 7 will move towards the end close to the support piece 6 and push into the support piece 6. The support piece 6 will expand towards the side close to the SiC sleeve 8, and the end of the support piece 6 will abut against the inner wall of the SiC sleeve 8. Finally, the SiC sleeve 8 can be pulled out by the pulling piece 4.

[0038] In this embodiment, asFigure 1 As shown, expansion openings are provided on two opposite sides of the end of the connecting member 3. In order to be used in cooperation with the connecting member 3, two support members 6 are provided. The two support members 6 are symmetrically arranged at one end of the connecting member 3 where the expansion openings are provided, and there is a gap between the opposite sides of the two support members 6. The expansion openings are communicated with the gap and are on the same horizontal line. After the top block 7 props up the two support members 6 from between the two support members 6 to cause them to expand, if the SiC sleeve 8 cannot be effectively pulled out by the pulling member 4, the top block 7 is further driven to displace through the stretching assembly, so that the end of the connecting member 3 is jacked up and expanded through the gap and the expansion openings, further enhancing the supporting force on the inner wall of the SiC sleeve 8, and the SiC sleeve 8 can be smoothly taken out.

[0039] In this embodiment, as Figure 2 and, Figure 3 and Figure 4 shown, the stretching assembly includes a lead screw 2. One end of the lead screw 2 extends into the connecting member 3 and the two support members 6, and extends outwards from between the two support members 6 to be connected to the top block 7. The other end of the lead screw 2 is screwed to the top of the connecting member 3 and a handle 1 is provided extending outwards.

[0040] In this embodiment, the circumferential diameter formed by the two support members 6 at one end close to the top block 7 is smaller than the circumferential diameter formed by the two support members 6 at one end close to the connecting member 3, and is larger than the circumferential diameter of the top block 7 at one end close to the two support members 6. During the process of the lead screw 2 displacing the top block 7, the top block 7 can effectively be jacked into the space between the two support members 6 to expand them outwards.

[0041] In this embodiment, the support member 6 is a expanding claw, and the expanding claw is made of high-elastic steel.

[0042] In this embodiment, the outer side of the support member 6 is provided with pointed teeth, and the setting of the pointed teeth can increase the frictional force between the support member 6 and the inner wall of the SiC sleeve 8.

[0043] In this embodiment, the periphery of the top block 7 has inclined surfaces, and the setting of the inclined surfaces can provide a certain supporting force for the inner wall of the support member 6.

[0044] In this embodiment, the pulling member 4 and the clamping member 5 are arranged at intervals, and the pulling member 4 is located above the clamping member 5. A plurality of clamping members 5 are provided, and the angles formed between the plurality of clamping members 5 and the connecting member 3 are equal. The clamping member 5 includes a first clamping arm 501 and a second clamping arm 502, and the first clamping arm 501 and the second clamping arm 502 are rotatably connected; the pulling member 4 is a pulling rod, and the pulling rods are symmetrically arranged outside the connecting member 3.

[0045] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
