Description

Technical Field

[0001] This utility model relates to the field of baking oven technology, and in particular to a large baking oven for easy-to-maintain carbon electrode production. Background Technology

[0002] In modern industry, carbon electrodes have become an indispensable component. In the metallurgical industry, carbon electrodes are crucial for electric arc furnaces. In these furnaces, they conduct high-ampere currents, generating high heat for melting metals. Their application significantly improves the efficiency of metal smelting processes, enabling the production of high-quality steel and non-ferrous metals. In the chemical industry, carbon electrodes are widely used in electrolysis processes, such as in aluminum production, where they participate in electrochemical reactions at the anode. However, the production of carbon electrodes faces numerous challenges. The baking stage is a critical but complex process. During baking, the raw carbon electrode precursor requires precise temperature and atmosphere control. Traditional baking methods often struggle to ensure uniform heating, leading to inconsistent final product quality. Furthermore, the harsh operating conditions within the baking furnace, including high temperatures and corrosive gas environments, pose a significant threat to the lifespan of both the furnace and the electrode itself. Moreover, as industry demands for carbon electrode performance, such as better conductivity and mechanical strength, existing production technologies have reached their limits. The lack of advanced baking equipment and technology not only affects the quality of carbon electrodes but also restricts the overall development of related industries. This urgently requires innovation in carbon electrode production, particularly in the design and operation of baking ovens, to meet the growing market demand.

[0003] Existing large-scale baking ovens using gas heating suffer from insecure heating pipes that are prone to loosening under the continuous impact of high-temperature gas and vibrations from equipment operation. This not only increases the risk of gas leaks but also causes uneven heating, affecting the quality of carbon electrode baking. Furthermore, the combustion equipment is bulky and lacks convenient relocation mechanisms. Once installed, moving it for production layout adjustments is extremely difficult, severely limiting the flexibility and convenience of equipment use. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a large baking oven for easy-to-maintain carbon electrode production.

[0005] This utility model is achieved using the following technical solution: a large baking oven for easy-to-maintain carbon electrode production, comprising a fire wall furnace, wherein a heating fire wall is fixedly connected inside the fire wall furnace, a heating port is provided at the top of the heating fire wall, a fire well is provided at the top of the heating fire wall, a cover plate is inserted into the inner wall of the fire well, an insert plate is inserted into the inner wall of the heating port, a support frame is provided at the top of the fire wall furnace, a support base is fixedly connected inside the support frame, a gas pipe is fixedly connected to the inner wall of the support base, a heating pipe is fixedly connected to the surface of the gas pipe, a heating chamber is provided inside the heating fire wall, a melting tank is provided at the top of the fire wall furnace, and casters are fixedly connected to the bottom of the support frame.

[0006] Through the above technical solution, casters are installed at the bottom of the support frame, giving the entire baking oven flexibility to move. Whether adjusting the equipment position within the production workshop to adapt to different production layouts, or moving the equipment to a suitable maintenance area during maintenance, the casters can easily and quickly move the equipment, improving its ease of use and versatility.

[0007] As a further improvement to the above scheme, the heating port is connected to the heating chamber, and the fire well is connected to the heating chamber.

[0008] As a further improvement to the above solution, the number of omnidirectional wheels is set to several.

[0009] As a further improvement to the above solution, the top of the insert plate is provided with a slot, and the top of the insert plate is provided with a fixing groove.

[0010] As a further improvement to the above solution, the slot is inserted into a heating pipe, and the slot is located at the center of the fixing groove.

[0011] With the above technical solution, the slot is opened on the top of the plug plate. By plugging it into the heating pipe, the plug plate is connected to the heating pipe, ensuring that the plug plate is fixed in position. At the same time, it guides the gas from the heating pipe to flow smoothly into the heating port, ensuring the accuracy of the gas delivery path.

[0012] As a further improvement to the above solution, a valve is fixedly connected to the surface of the heating pipe, and a clamp is fixedly connected to the surface of the heating pipe.

[0013] Through the above technical solution, the heating pipe guides the gas delivered from the gas pipeline to the heating port, and controls the gas flow through the valve to regulate the amount of gas entering the heating chamber, thereby achieving the control of the heating intensity.

[0014] As a further improvement to the above solution, the card plate is inserted into the fixing slot.

[0015] Through the above technical solution, the clamping plate is fixed on the surface of the heating pipe and is inserted into the fixing groove of the insert plate to position and fasten the insert plate, preventing the insert plate from shifting during operation and ensuring the stability and sealing of the gas transmission channel at the heating port.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model features an insert plate that is tightly inserted into the heating pipe via a slot. The fixing groove and the locking plate precisely match, forming an extremely stable connection structure. This design not only effectively prevents the heating pipe from loosening under harsh conditions of high temperature and high pressure, ensuring stable gas delivery and continuous heat supply, and maintaining stable equipment operation, but also prevents parts from shifting or being damaged due to accidental contact during personnel inspection operations, even in complex environments. This greatly reduces operational risks and provides dual protection for the safe operation of the equipment and the safety of personnel.

[0017] This invention features casters; multiple casters at the bottom of the support frame give the baking oven excellent mobility. Whether adjusting its position within the production workshop or moving it to a specific area for equipment maintenance, it can be easily accomplished, improving the ease of use of the equipment.
