Description

Technical Field

[0001] This utility model relates to the field of high-temperature furnace technology for silicon molybdenum rods, specifically an energy-saving high-temperature furnace for silicon molybdenum rods. Background Technology

[0002] The high-temperature furnace for silicon molybdenum rods mainly consists of high-purity silicon molybdenum rods, heat-resistant sintered quartz plates, and polycarbonate shells. Before use, the silicon molybdenum rods should be preheated to an appropriate temperature, and then the voltage should be gradually increased to prevent damage to the components due to excessive voltage difference. During use, rapid temperature changes should be avoided to prevent the silicon molybdenum rods from cracking. The surface condition and connection parts of the silicon molybdenum rods should be checked regularly to identify and deal with problems in a timely manner to ensure the normal operation of the furnace.

[0003] In some existing high-temperature furnaces for silicon molybdenum rods, when the silicon molybdenum rods are energized, the silicon molybdenum rods generate resistance heat. The heat is transferred to the inside of the furnace through thermal radiation and thermal convection, causing the temperature inside the furnace to gradually rise, thereby heating the workpieces placed in the furnace.

[0004] Existing high-temperature furnaces for silicon molybdenum rods have the following problems: When using a high-temperature furnace for silicon molybdenum rods, the furnace generates a large amount of heat during operation, and the heat is dissipated to the surrounding environment through the furnace surface. This not only leads to energy waste and increases production costs, but also reduces the heating efficiency of the furnace. Therefore, we propose an energy-saving high-temperature furnace for silicon molybdenum rods. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This embodiment provides a technical solution: an energy-saving high-temperature furnace for melting silicon molybdenum rods, including an outer shell 1. Silicon molybdenum rods 3 are evenly distributed at both ends of the top wall of the outer shell 1. Quartz plates 5 are arranged on the four inner walls of the outer shell 1, and ceramic fiber plates 4 are arranged on the inner sides of the quartz plates 5. It also includes a heat insulation component 6. A microcontroller 8 is installed outside the outer shell 1. The input terminal of the microcontroller 8 is electrically connected to an external power supply, and the input terminals of the silicon molybdenum rods 3 are all electrically connected to the output terminals of the microcontroller 8. It also includes a fixing component 7, which includes an L-shaped bracket 71 and a fixing block 73 for installation. L-shaped brackets 71 are provided on the left and right sides of the rear end of frame 61, and fixing blocks 73 are provided on the rear sides of the left and right ends of the outer shell 1. The front ends of the L-shaped brackets 71 are respectively installed with the insertion holes on the inner side of the longitudinally adjacent fixing blocks 73. The fixing assembly 7 also includes insertion strips 72, sliding plates 74 and pull rods 77. The sliding plates 74 are slidably connected inside the fixing blocks 73, and the insertion strips 72 are fixedly connected to the inner side of the sliding plates 74. The outer side of the L-shaped brackets 71 is provided with evenly distributed insertion slots, and the inner ends of the insertion strips 72 are respectively connected with the transversely adjacent insertion slots. The slide plate 74 is installed in a groove. Pull rods 77 are fixedly connected to the outer ends of the slide plate 74. The fixing assembly 7 also includes springs 75 and telescopic rods 76. Symmetrical telescopic rods 76 are fixedly connected between the outer side of the slide plate 74 and the inner side of the laterally adjacent fixing block 73. Springs 75 are fitted onto the outside of each telescopic rod 76. A door 2 is hinged to the front end of the outer casing 1. When the mounting frame 61 enters the interior of the slide groove 65, pulling the pull rods 77 at both ends will pull the connector strip 72 into the interior of the fixing block 73 via the slide plate 74. The L-shaped bracket 71 will be inserted into the inside of the fixing block 73. Then the pull rod 77 will be released, and the insertion strip 72 will be inserted into the insertion slot under the rebound of the spring 75 and the telescopic rod 76. The workpiece to be processed will be placed into the inside of the outer shell 1. Then the box door 2 will be closed. Then the silicon molybdenum rod 3 will be operated by controlling the single-chip microcomputer 8. When the silicon molybdenum rod 3 is energized, due to its own resistance, the electrical energy is converted into heat energy, and the temperature of the silicon molybdenum rod rises rapidly. The heat generated is transferred to the ceramic fiber plate 4 and the quartz plate 5 through thermal radiation and thermal convection, so that the workpiece inside the outer shell 1 is heated.

[0024] Insulation component 6: It includes a mounting frame 61, an asbestos board 62, a fiberglass board 63, a rock wool board 64, and a sliding groove 65. The inner wall of the outer shell 1 is provided with a sliding groove 65, and the mounting frame 61 is slidably connected inside the sliding groove 65. The inner wall of the mounting frame 61 is provided with an asbestos board 62, the outer wall of the asbestos board 62 is provided with a fiberglass board 63, and the outer wall of the fiberglass board 63 is provided with a rock wool board 64. The mounting frame 61 is a rock wool frame. When using a silicon molybdenum rod high-temperature furnace, the mounting frame 61 containing the asbestos board 62, fiberglass board 63, and rock wool board 64 is first inserted into the sliding groove 65. Then, the mounting frame 61 and the asbestos board 62, fiberglass board 63, and rock wool board 64 inside the mounting frame 61 provide insulation, which greatly reduces heat loss and improves energy utilization.

[0025] The working principle of the energy-saving high-temperature furnace for silicon molybdenum rods provided by this utility model is as follows: When using the high-temperature furnace for silicon molybdenum rods, first insert the mounting frame 61 containing asbestos board 62, fiberglass board 63, and rock wool board 64 into the slide groove 65. Then, when the mounting frame 61 enters the slide groove 65, by pulling the pull rods 77 at both ends, the pull rods 77 will pull the insertion strip 72 into the fixing block 73 through the sliding plate 74. The L-shaped bracket 71 will be inserted into the fixing block 73. Then, the pull rods 77 will be released, and the insertion strip 72 will be inserted under the rebound of the spring 75 and the telescopic rod 76. The slot is inserted, and the workpiece to be processed is placed inside the outer shell 1. Then, the door 2 is closed. Then, the silicon molybdenum rod 3 is operated by controlling the single-chip microcomputer 8. When the silicon molybdenum rod 3 is energized, due to its own resistance, electrical energy is converted into heat energy, and the temperature of the silicon molybdenum rod rises rapidly. The heat generated is transferred to the ceramic fiber board 4 and the quartz board 5 through thermal radiation and thermal convection, so that the workpiece inside the outer shell 1 is heated. Then, the heat is insulated by the mounting frame 61 and the asbestos board 62, glass fiber board 63 and rock wool board 64 inside the mounting frame 61, which greatly reduces heat loss and improves energy utilization.

[0026] It is worth noting that the silicon molybdenum rod 3 disclosed in the above embodiments can all be selected from STA-MS17, and the single-chip microcomputer 8 controls the operation of the silicon molybdenum rod 3 using methods commonly used in the prior art.
