[0032] The embodiments of the utility model will be described in detail below with reference to the drawings. Embodiment

[0033] As Figures 1-3 shown, the embodiment provides a carbon rod plug for blocking the eye of an industrial silicon furnace, comprising:

[0034] The first plug 1 is provided with external threads on the outer wall thereof;

[0035] The second plug 2 is provided with a threaded groove at the end thereof along the central axis direction of the second plug 2, and the first plug 1 and the second plug 2 are connected through threads;

[0036] The support rod 3 is arranged at the other end of the first plug 1 and is used for lifting the second plug 2 to block the eye.

[0037] In use, the cast iron plug is used as the first plug 1, the carbon rod is reprocessed to form the second plug 2, the external threads are arranged on the outer wall of the first plug 1, the threaded groove is arranged in the second plug 2, so that the first plug 1 can be connected to the second plug 2 through threads, then the support rod 3 is arranged at the other end of the first plug 1, the support rod 3 is convenient for the staff to hold and push back and forth, so that the second plug 2 impacts the eye material located at the eye, and because the second plug 2 is made of graphite material, it is not affected by high temperature and does not melt, so as to not affect the quality of the final product.

[0038] In one of the embodiments, as Figure 2 shown, the outer wall of the support rod 3 is paved with the fixing belt 71, both ends of the fixing belt 71 are provided with the fixing plate 7, and the outer walls of the two fixing plates 7 are provided with the support plate 6.

[0039] In use, by setting the support plate 6 at the first roller 5 in the screen 4, and then passing the support rod 3 through the gap between the first roller 5 and the fixing belt 71 between the two fixing plates 7, the support plate 6 can be limited left and right, preventing the support rod 3 from deviating left and right when the worker impacts the furnace eye material, so that the impact position is not accurate, thereby increasing the operation time.

[0040] In one embodiment, as shown in Figure 2 The horizontal distance between the two fixing plates 7 is equal to the outer diameter of the support rod 3.

[0041] In use, the horizontal distance between the two fixing plates 7 is equal to the outer diameter of the support rod 3, which can limit the support rod 3 in the horizontal direction, avoiding the support rod 3 from deviating left and right during plugging, which affects the plugging operation of the furnace eye.

[0042] In one embodiment, as shown in Figure 2 and Figure 3 Each fixing plate 7 is rotationally connected with the adjacent support plate 6.

[0043] In use, the fixing plate 7 is rotationally connected with the support plate 6, so that the support rod 3 can rotate on the first roller 5 with the center axis of the first roller 5 as the rotation axis, which is generally used when starting the plugging preparation operation or when the impact position of the support plate 6 needs to be adjusted, avoiding the influence of the fixing belt 71 on the support rod 3.

[0044] In one embodiment, as shown in Figure 2 and Figure 3 The inside of one of the fixing plates 7 is provided with a first through hole 70 for the fixing belt 71 to pass through, and the side wall of the fixing plate 7 facing the support rod 3 is provided with a second through hole 72 communicating with the first through hole 70; the inside of the fixing plate 7 is provided with a support rod 73 located in the second through hole 72, and a torsion spring 74 is sleeved on the support rod 73, one end of the torsion spring 74 is provided with a clamping block, and the outer wall of the fixing belt 71 is provided with a plurality of clamping grooves 76 clamped with the clamping block; the top of the clamping block is provided with a push block 75 passing through the second through hole 72.

[0045] In use, the fixing band 71 can pass through the first through hole 70 to adjust the length, thereby limiting the support rod 3 of different sizes. Specifically, one end of the fixing band 71 is fixedly connected to the top of one of the fixing plates 7, and the other end passes through the first through hole 70. The first through hole 70 is opened from the top of the fixing plate 7 to the bottom of the fixing plate 7, so that the fixing band 71 can enter from the top of the fixing plate 7 and pass out from the bottom of the fixing plate 7. A second through hole 72 is opened on the side wall of the fixing plate 7, and the second through hole 72 is located on the side wall of the fixing plate 7 facing the support rod 3. A support rod 73 is arranged in the second through hole 72. A torsional spring 74 is sleeved on the support rod 73. One end of the torsional spring 74 is provided with a clamping block, and the other end is abutted against the inner wall of the fixing plate 7 located in the second through hole 72. A clamping groove 76 is opened on the fixing band 71 at the position passing through the first through hole 70. The clamping block can limit the fixing band 71 through the clamping groove 76. When the length of the fixing band 71 needs to be limited, the fixing band 71 can be pulled down. When the length of the fixing band 71 needs to be limited, the fixing band 71 needs to be pulled up to achieve the adjustment effect.

[0046] In the above embodiment, since the temperature around the furnace hole is very high during the process of plugging the furnace hole, the material of the fixing band 71 needs to be selected as a flexible material resistant to high temperature and having a certain strength, which can limit the support plate 6 in the case of resisting high temperature.

[0047] In one of the embodiments, as shown in Figure 5 Each fixing plate 7 is provided with a second groove 77 at one end facing the support plate 6. A second roller 78 is rotatably connected in the second groove 77.

[0048] In use, the support rod 3 moves back and forth in the screen 4 to plug the furnace hole. During the plugging process, the support rod 3 is limited to slide left and right by the two fixing plates on the support plate 6. The second groove 77 is opened on the fixing plate, and the second roller 78 is rotatably connected in the second groove 77. The second roller 78 is in rolling contact with the support rod 3, so that the support rod 3 moves more smoothly between the two fixing plates.

[0049] In one of the embodiments, as shown in Figure 1 A pull ring 8 is hinged to the outer wall near the other end of the support rod 3.

[0050] In use, the pull ring 8 is hinged to the outer wall of the other end of the support rod 3, so that after the staff completes the plugging operation of the furnace hole, the pull ring 8 is opened from the support rod 3. After being opened, the staff holds the pull ring 8 and pulls the support rod 3 away from the industrial silicon furnace, so that the support rod 3 can be more labor-savingly taken off the screen 4, saving the physical consumption of the staff.

[0051] In one embodiment, as shown in Figure 4 each support plate 6 comprises a first support plate body 60 and a second support plate body 61, the first support plate body 60 and the second support plate body 61 are hinged, and a first recess 62 is formed on the opposite side of the first support plate body 60 and the second support plate body 61, and the two first recesses 62 form a complete third through hole; a buckle 601 is arranged on the side wall of the first support plate body 60, and a clasp 611 matched with the buckle 601 is arranged on the side wall of the second support plate body 61.

[0052] In use, each support plate 6 is divided into a first support plate body 60 and a second support plate body 61, and adjacent first support plate bodies 60 and second support plate bodies 61 are hinged to each other, and the hinge point is located at the top of the first support plate body 60 and the second support plate body 61, so that the support plate 6 can be detachably installed on the first roller 5 of the screen 4. A first recess 62 is formed on the opposite side walls of the first support plate body 60 and the second support plate body 61, and when the first support plate body 60 and the second support plate body 61 are rotated to contact each other, the first recesses 62 formed on the two support plate bodies 6 form a complete third through hole, which is used for the first roller 5 of the screen 4 to pass through, and the first roller 5 is rotatably connected with the first support plate body 60 and the second support plate body 61 at this time. The buckle 601 is arranged on the outer wall of the first support plate body 60, and the clasp 611 is arranged on the outer wall of the second support plate body 61, and the buckle 601 and the clasp 611 are matched with each other, and after the first support plate body 60 and the second support plate body 61 are close to each other, the buckle 601 and the clasp 611 are buckled, and at this time, the support plate 6 is rotatably connected with the first roller 5.

[0053] In the above embodiment, when the first support plate body 60 and the second support plate body 61 are locked by the buckle 601 and the clasp 611, the bottom of the support plate 6 should be in contact with the inner bottom of the screen 4, and it is worth noting that the inner bottom of the screen 4 mentioned here is the window of the screen 4 where the first roller 5 is arranged, and the inner bottom position of the window is used to limit the displacement of the support plate 6, so as to avoid the displacement of the support plate 6 during the process of plugging the furnace eye.

[0054] In one embodiment, as shown in Figure 3 the end of the fixed band 71 passing through the first through hole 70 is provided with a spherical blocking part 79.

[0055] When in use, the spherical blocking part 79 can avoid the fixed band 71 from falling off from the first through hole 70 on the fixed plate. Specifically, the spherical blocking part 79 is arranged at the end of the fixed band 71 passing through the first through hole 70, and the outer diameter of the spherical blocking part 79 is larger than the inner diameter of the first through hole 70, so that the fixed band 71 cannot slide out of the first through hole 70 to cause falling off by adjusting the support rod 3 when the knob 75 is pushed away to make the torsion spring 74 disengage from the clamping groove 76 on the fixed band 71.

[0056] In one of the embodiments, the fixed band 71, the fixed plate, the support plate 6, the second roller 78, the support rod 73, the torsion spring 74, the knob 75, the clamping ring 611, the buckle 601 and the pull ring 8 are made of high-temperature-resistant material.

[0057] When in use, since the operation of plugging the furnace hole is close to the industrial silicon furnace, and the working temperature of the industrial silicon furnace is relatively high, the fixed band 71, the fixed plate, the support plate 6, the second roller 78, the support rod 73, the torsion spring 74, the knob 75, the clamping ring 611, the buckle 601 and the pull ring 8 are made of high-temperature-resistant material to improve the service life of the whole device.

[0058] Finally, it should be noted that: the above is only the preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations, and in the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other at will.
