[0002] Graphite felt is a carbon fiber graphite soft felt. Its main use is as insulation for single crystal silicon smelting furnaces. During the production process of graphite felt, a high-temperature furnace is required to heat the raw material graphite felt at high temperature.

[0003] The existing equipment for heating the graphite felt only places the graphite felt raw material flat in the furnace for heating treatment. During the treatment process, the graphite felt is stacked on each other, resulting in uneven heating, which in turn causes a long overall heating treatment time. It also causes inconsistent treatment effects on the graphite felt and requires returning to the furnace for reheating. In addition, after the graphite felt is heated, it is necessary to wait for the furnace to cool down naturally before opening the furnace to take out the material. The graphite felts stacked on each other not only heat slowly, but also cool poorly, and it takes a long time to cool down, which is inconvenient to use.

[0004] The utility model proposes a new solution to the above problems. Utility Model Content

[0005] The main purpose of the utility model is to solve the problems that the graphite felts in the existing high-temperature furnace for graphite felt production are stacked on each other, resulting in uneven heating and too long heating time, and the existing high-temperature furnace for graphite felt production has a long natural cooling time after heating is completed, and to provide a high-temperature furnace for graphite felt production.

DETAILED DESCRIPTION

[0025] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0026] like Figure 1-Figure 6 As shown, the high-temperature furnace for producing graphite felt provided in this embodiment includes a furnace body 1, and a cover plate 2 fixedly connected to the top of the furnace body 1 by bolts, an electric heating plate 11 is fixedly installed on the inner wall of the furnace body 1, a motor 3 is fixedly installed on the bottom of the furnace body 1, and the output end of the motor 3 is fixedly connected to a connecting shaft 4 located on the inner side of the furnace body 1, and a placing mechanism 5 is threadedly installed on the outer side of the connecting shaft 4, and the placing mechanism 5 includes a threaded sleeve 6 threadedly connected to the outer side of the connecting shaft 4, a support plate 7 is fixedly connected to the top outer wall of the threaded sleeve 6, a hanging rod 8 is installed on the top of the support plate 7, a limiting rod 9 is rotatably installed on the bottom outer wall of the threaded sleeve 6, an electric telescopic rod 10 is installed between the limiting rod 9 and the threaded sleeve 6, and a limiting groove 12 cooperating with the limiting rod 9 is opened on the inner wall of the furnace body 1.

[0027] By setting the connecting shaft 4, the placing mechanism 5 and the limiting rod 9, the motor 3 can rotate forward and backward to drive the placing mechanism 5 to move up and down as a whole. When it is moved up out of the furnace body 1, it is convenient to install the graphite felt without being restricted by the smaller space inside the furnace body 1. At the same time, after heating is completed, the heated graphite felt is moved up out of the furnace body 1, which can accelerate cooling and improve work efficiency; when the placing mechanism 5 is completely moved down into the furnace body 1, the electric telescopic rod 10 is started to drive the limiting rod 9 to disengage from the limiting groove 12. At this time, the placing mechanism 5 can rotate with the rotation of the connecting shaft 4 to improve the heating efficiency; by setting the hanging rod 8, the hanging rod 8 and the support plate 7 are detachable, and the hanging rod 8 can be removed, and the graphite felt can be hung on the outside first and then placed on the support plate 7, which is convenient for installation. At the same time, by setting the hanging rod 8, the graphite felt can be arranged neatly, the heating is uniform, and the heating efficiency is improved.

[0028] In this embodiment, if Figure 1 , Figure 3 and Figure 4 As shown, a mounting hole 101 matched with a bolt is fixedly connected on the top outer wall of the furnace body 1, a matching hole 201 matched with a bolt is fixedly connected on the outer wall of the cover plate 2, and a lifting ear 202 is fixedly connected on the top of the cover plate 2. The arrangement of the mounting hole 101 and the matching hole 201 facilitates the installation of the cover plate 2, and the arrangement of the lifting ear 202 facilitates the opening and closing of the cover plate 2.

[0029] In this embodiment, if Figure 1 , Figure 5 and Figure 6 As shown, a slot 701 is provided in the middle of the support plate 7, a clip 801 matching the slot 701 is fixedly connected to the middle of the hanging rod 8, baffles 802 are fixedly connected to both ends of the hanging rod 8, and a hanging slot 702 matching the hanging rod 8 is provided on the top of the support plate 7. The arrangement of the clip 801 and the slot 701 prevents the graphite felt on both sides of the hanging rod 8 from sliding toward the heavier end due to different weights, and the arrangement of the baffle 802 prevents the graphite felt from slipping off.

[0030] In this embodiment, if Figure 1 , Figure 5 and Figure 6 As shown, a first hinge seat 601 that is rotatably matched with the limit rod 9 is fixedly connected to the side wall of the threaded sleeve 6, a rotating column 901 is fixedly connected to one end of the limit rod 9, and a second hinge seat 14 that is rotatably matched with the electric telescopic rod 10 is fixedly connected to the top of the limit rod 9 and the side wall of the threaded sleeve 6. Through the arrangement of the second hinge seat 14, both ends of the electric telescopic rod 10 are rotatably connected to the limit rod 9 and the threaded sleeve 6, thereby being able to drive the limit rod 9 to rotate.

[0031] In this embodiment, if Figure 1 , Figure 2 and Figure 5As shown, the outer wall of the connecting shaft 4 is fixedly connected with a bottom plate 401 located inside the furnace body 1, and the outer wall of the connecting shaft 4 is provided with an external thread 402 located above the bottom plate 401. The furnace body 1 is a heat-insulating furnace body, and the bottom of the cover plate 2 is fixedly connected with a heat-insulating cotton 13 located inside the furnace body 1. The setting of the bottom plate 401 is used to limit the start of the threaded sleeve 6, so as to prevent the threaded sleeve 6 from moving down too low and causing wear on the inner wall of the furnace body 1, and the setting of the heat-insulating cotton 13 is used to achieve a heat-insulating effect.

[0032] In this embodiment, if Figure 1-Figure 6 As shown, the working process of a high temperature furnace for producing graphite felt provided in this embodiment is as follows:

[0033] Step 1: Open the cover plate 2, reverse the motor 3, move the placement mechanism 5 out of the furnace body 1 as a whole, remove the hanging rod 8, install the graphite felt, and then hang the hanging rod back on the support plate 7;

[0034] Step 2: The motor 3 is rotated forward to move the placement mechanism 5 downward as a whole until the threaded sleeve 6 contacts the bottom plate 401. At this time, the electric telescopic rod 10 is started to make the limit rod 9 disengage from the limit groove 12. At this time, the placement mechanism 5 rotates with the connecting shaft 4, the cover plate 2 is closed, and the electric heating plate 11 is started for heating;

[0035] Step 3: After heating is completed, the cover plate 2 is opened, and the electric telescopic rod 10 is started so that the limiting rod 9 enters the limiting groove 12, and the motor 3 is reversed so that the placement mechanism 5 is moved out of the furnace body 1 as a whole for cooling.

[0036] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
