Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric heating equipment technology, specifically to an ultra-high temperature graphite heating device. Background Technology
[0002] Graphite has excellent thermal conductivity, allowing graphite heaters to evenly transfer heat to the object being heated, preventing localized overheating. It also exhibits strong corrosion resistance, making it suitable for use in high-temperature and high-pressure environments. However, graphite is a rare material, resulting in a higher cost for graphite heaters. Furthermore, graphite is brittle, so care should be taken to avoid impacts during use. Overall, graphite heaters offer excellent heating performance and corrosion resistance, leading to their wide application in metallurgy, chemistry, and analytical fields.
[0003] In the field of industrial heating, most heating methods cannot achieve ultra-high temperature heating, but graphite heaters can heat up to 2600 degrees Celsius, and their excellent performance meets this requirement. Utility Model Content
[0004] The purpose of this utility model is to provide an ultra-high temperature graphite heating device with a simple structure, convenient operation, and the ability to heat objects of various irregular shapes. Its features include: a furnace shell, an ultra-high temperature insulation layer around the inner wall of the furnace shell, a furnace door on the front of the furnace shell, flanges on the left and right sides of the furnace shell connected to the exhaust pipe, a graphite heating plate installed inside the furnace, a tooling fixture installed inside the ultra-high temperature insulation layer, and water-cooled electrode connection ports on both sides of the shell for powering the graphite heating plate.
[0005] Furthermore, there are two flanges, which are symmetrically arranged on the upper part of both sides of the furnace shell.
[0006] Furthermore, the water-cooled electrode connection port is provided with two ports, which are arranged symmetrically.
[0007] Furthermore, the water-cooled electrode connection port is located below the flanges on both sides of the furnace body shell.
[0008] Compared with existing technologies, this invention has a simple structure and is easy to operate. It can heat objects of various irregular shapes at ultra-high temperatures, effectively solving the preheating and heating problems of components during production and maintenance. The graphite heating plate of this invention is connected to a water-cooled cable via a water-cooled connector. The furnace body is insulated with multiple layers of heat insulation. The exterior is equipped with flange holes for installing exhaust pipes. Heat-resistant fixtures are installed inside the furnace body to meet the fixing requirements of heated parts of different sizes and shapes. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0012] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0013] An ultra-high temperature graphite heating device includes a furnace shell 1, an ultra-high temperature insulation layer 3 surrounding the inner wall of the furnace shell 1, a furnace door on the front of the furnace shell 1, flanges 2 on the left and right sides of the furnace shell for connection to a vacuum pipe, a graphite heating plate 5 installed inside the furnace, and a tooling fixture 6 installed inside the ultra-high temperature insulation layer 3. The tooling fixture 6 can be adjusted in position as needed. Water-cooled electrode connection ports 4 for powering the graphite heating plate are also provided on both sides of the shell. The furnace shell 1 is connected to the vacuum pipe through the flange holes 2 to perform vacuum treatment inside. The ultra-high temperature insulation layer 3 is made of multi-layer insulation material to meet the insulation requirements.
[0014] Two flanges 2 are provided, symmetrically arranged on the upper sides of the furnace shell. Two water-cooled electrode connection ports 4 are provided, symmetrically arranged. The water-cooled electrode connection ports are located below the flanges on both sides of the furnace shell. The graphite heating equipment uses tungsten plates and boron nitride materials for insulation. The power supply cable for the graphite heating equipment is a water-cooled cable connected to a water-cooled connector. A sealed oven is used, and heating is performed after the interior is evacuated, thereby avoiding the safety hazards caused by gas expansion under high temperature conditions.
[0015] When operating, first place the object to be heated into the furnace body, fix it with tooling fixtures, close the furnace door to ensure a seal, turn on the vacuum pump to evacuate the inside of the furnace body, set the required power and time to start the machine, do not open the furnace door immediately after heating is completed, wait for the temperature to cool down before opening the furnace door to complete the experiment.
[0016] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
