Description

Technical Field

[0001] This utility model relates to a high-temperature resistant treatment device for silicon carbide burner sleeves, belonging to the technical field of silicon carbide burner sleeves. Background Technology

[0002] Silicon carbide burner sleeves are ceramic products made primarily of silicon carbide through high-temperature sintering. They are made from recrystallized silicon carbide and reaction-sintered silicon carbide, and feature high strength, high hardness, high wear resistance, and high thermal shock resistance. They maintain stable performance under extremely harsh working conditions, have a low coefficient of thermal expansion, effectively resist thermal stress at high temperatures, and extend service life. They also exhibit excellent thermal shock resistance, maintaining structural integrity even under drastic temperature changes.

[0003] Chinese Patent Publication No. (CN 209853740 U) discloses a high-temperature silicon carbide oxidation device, including a high-temperature furnace with a furnace cover on top. The furnace has a high-temperature chamber inside, and four equally spaced protrusions are arranged in a ring on the outer circumference of the furnace near the top. Threaded holes are provided on the protrusions. This high-temperature silicon carbide oxidation device uses heating elements to easily increase the furnace temperature and perform high-temperature oxidation on silicon carbide. It also includes a shelf mechanism for placing silicon carbide, and a water-cooling mechanism to quickly remove heat from the high-temperature chamber after use, achieving rapid cooling and improving work efficiency. This solves the problem of existing high-temperature silicon carbide oxidation equipment being difficult to cool down quickly after use.

[0004] When performing high-temperature oxidation treatment on silicon carbide burner sleeves, a high-temperature oxidation furnace is used. The furnace cover still needs to be opened and closed manually by the operator, which is cumbersome and inconvenient. At the same time, the internal temperature of the oxidation furnace is high, and when the operator opens the furnace cover manually, the oxidation furnace is prone to causing heat radiation burns or workpiece burns, thereby threatening the safety of the operator and making it inconvenient for the operator to use.

[0005] To address this, a high-temperature resistant treatment device for silicon carbide burner sleeves is proposed. Utility Model Content

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1-6 As shown, this utility model embodiment provides a high-temperature resistant treatment device for silicon carbide burner sleeves, comprising:

[0033] The high-temperature oxidation assembly 1 includes an oxidation furnace 101, a furnace cover 102 on the top of the oxidation furnace 101, an mounting plate 103 fixedly installed on the surface of the oxidation furnace 101, a heating tube 104 fixedly installed at the bottom of the inner cavity of the oxidation furnace 101, an electric heating wire 105 fixedly installed in the inner cavity of the heating tube 104, a bracket 106 fixedly installed at the bottom of the furnace cover 102, and an air inlet valve 107 fixedly installed at the top of the furnace cover 102.

[0034] The lifting assembly 2 includes a servo motor 201 and an external gear ring 203. The servo motor 201 is fixedly mounted on the top of the mounting plate 103, and the external gear ring 203 is located at the bottom of the mounting plate 103. Driven gears 204 are movably connected to all three sides of the bottom of the mounting plate 103. The surfaces of the three driven gears 204 mesh with the surfaces of the external gear ring 203. Lead screws 205 are fixedly mounted on the top of each of the three driven gears 204. Screw blocks 206 are threadedly connected to the surfaces of the three lead screws 205, and screw blocks 206 are fixedly mounted on the inner sides of the three screw blocks 206. Mounting rods 207, the other ends of which are fixedly mounted on the top of the furnace cover 102. The output end of the servo motor 201 is fixedly connected to the transmission gear 202. The surface of the transmission gear 202 meshes with the surface of the external gear ring 203. The thread directions of the three lead screws 205 are consistent with each other, and the thread pitch of the three lead screws 205 is the same. The control panel 3 is fixedly mounted on the surface of the oxidation furnace 101. The input ends of the electric heating wire 105, the servo motor 201 and the air inlet valve 107 are all electrically connected to the output end of the control panel 3.

[0035] By setting up the lifting component 2, the output of the servo motor 201 causes the lead screw 205 to drive the mounting rod 207 and the furnace cover 102 to rise and fall. By adjusting the height of the furnace cover 102, the furnace cover 102 can easily move the bracket 106 out of the inner cavity of the oxidation furnace 101, which is convenient for the operator to pick up and put down materials. At the same time, it also avoids the situation where the operator is burned when opening the furnace cover 102 by himself due to the high temperature inside the oxidation furnace 101, thus ensuring the safety of the operator and making it convenient for the operator to use.

[0036] Example 2

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in one embodiment, limit rods 208 are fixedly installed around the top of the mounting plate 103, and three screw blocks 206 are slidably connected to the surfaces of the three limit rods 208. An annular groove 209 is provided at the bottom of the mounting plate 103, and the top of the external toothed ring 203 is movably connected to the top of the inner cavity of the annular groove 209 through a bearing. A base plate 108 is fixedly installed at the bottom of the oxidation furnace 101, and anchor bolts 109 are threaded around the top of the base plate 108. A temperature sensor 110 is fixedly installed on the top of the furnace cover 102, and the detection end of the temperature sensor 110 extends into the inner cavity of the oxidation furnace 101.

[0038] By setting the limit rod 208, the movement of the screw block 206 can be limited to prevent it from rotating synchronously with the lead screw 205. By setting the annular groove 209, the outer toothed ring 203 can be limited to prevent it from deviating during rotation, thus affecting the lifting and lowering of the furnace cover 102 and the bracket 106. By setting the anchor bolts 109, the overall equipment can be stabilized to prevent the equipment from shaking due to accidental collisions. By setting the temperature sensor 110, the temperature in the inner cavity of the oxidation furnace 101 can be detected to facilitate understanding the temperature in the inner cavity of the oxidation furnace 101.

[0039] In operation, this invention works as follows: The silicon carbide burner sleeve is placed inside the bracket 106. Then, the servo motor 201 outputs power, causing the transmission gear 202 to rotate the external gear ring 203. The external gear ring 203 simultaneously rotates the driven gear 204, causing the lead screw 205 to move the screw block 206 downwards. At this time, the screw block 206 simultaneously moves the furnace cover 102, bracket 106, and silicon carbide burner sleeve downwards. Once the bracket 106 and silicon carbide burner sleeve are inside the oxidation furnace 101, the electric heating wire 105 begins heating, and the air inlet valve 107 directs air into the oxidation furnace 101. Air is injected into the cavity to begin the high-temperature oxidation of the silicon carbide burner sleeve. After oxidation is completed, the reverse output of the servo motor 201 causes the transmission gear 202 to drive the external gear ring 203 to rotate in the opposite direction. The external gear ring 203 synchronously drives the driven gear 204 to rotate, which in turn causes the driven gear 204 to drive the lead screw 205 to rotate in the opposite direction. The screw block 206 drives the mounting rod 207, the furnace cover 102, and the bracket 106 to move upward. At this time, the bracket 106 moves the silicon carbide burner sleeve out of the inner cavity of the oxidation furnace 101, thus completing the lifting and lowering of the furnace cover 102 and the bracket 106.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
