[0029] It should be understood that the embodiments of the present application shown in the example embodiments are only illustrative. Although only a few embodiments are described in detail in the present application, those skilled in the art can easily appreciate that various modifications are possible without departing from the teachings of the subject matter of the present application. Accordingly, all such modifications should be included within the scope of the present application. Other substitutions, modifications, changes and omissions can be made to the design, operating conditions and parameters of the following example embodiments without departing from the spirit of the present application.
[0030] The present application provides a novel electrode conductive cross arm system suitable for carbonization furnace, please refer to Figure 1 、 Figure 2 and Figure 3 , comprising: cross arm 1, lifting column 2, water-cooled cable 3, furnace cover 4 and secondary short net 5;
[0031] The cross arm 1 and the lifting column 2 are connected vertically, and the lifting column 2 is located at the edge of the furnace cover 4;
[0032] The secondary short net 5 connects the front end of the cross arm 1 through the water-cooled cable 3;
[0033] The rear end of the cross arm 1 is connected to cooling water.
[0034] The novel cross arm 1 of the present application effectively solves the problem of overlong design of the cross arm 1, and at the same time, the water-cooled cable 3 is separated from the cross arm 1, which directly supplies power to the conductive copper tile of the electrode holder, shortens the power supply path length, reduces the power loss, improves the smelting strength, and the effect is very obvious.
[0035] Through scientific calculation and reasonable design, the length of the cross arm 1 is effectively shortened, thereby reducing the complexity and manufacturing cost of the equipment. The design of separating the water-cooled cable 3 from the cross arm 1 is innovatively adopted, which avoids the safety hazards and maintenance difficulties that may be caused by the direct connection of the water-cooled cable 3 and the cross arm 1 in the traditional way. The present application adopts the mode of directly supplying power to the conductive copper tile of the electrode holder, which significantly shortens the power supply path length, thereby effectively reducing the power loss.
[0036] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the transformer is star-connected.
[0037] In star connection, the three windings of a transformer are connected to a common junction, forming a structure similar to a star. This common junction is usually referred to as the neutral point. The first end of each winding is then brought out separately for connection to external circuits. In step-down transformers, the primary winding is usually star-connected to reduce the input voltage and current. This allows the transformer to operate more efficiently and reduces energy loss.
[0038] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the cross arm 1 corresponds to the star connection of the transformer.
[0039] As a support structure for the transformer or its components, the cross arm 1 ensures that the transformer can be stably fixed and installed when star-connected. By providing the necessary structural support, the cross arm 1 helps reduce vibration and displacement of the transformer during operation, thereby improving its stability and reliability.
[0040] The cross arm 1 assumes the function of electrical connection, such as connecting the star-connected windings of the transformer to external circuits. By optimizing the design and layout of the cross arm 1, energy loss and signal interference in electrical connections can be reduced, improving the efficiency and quality of power transmission.
[0041] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the secondary short net 5 is insulated and arranged above the carbonization furnace.
[0042] After being hung with insulation, the secondary short net 5 maintains good electrical isolation from the surrounding environment or other components. This isolation helps reduce electrical interference and noise, improving the electrical performance of the system. At the same time, insulation hanging can prevent current leakage, ensuring stable operation of the system.
[0043] This makes the secondary short net 5 more easily maintained and repaired. Due to the relatively simple and easy-to-operate hanging structure, workers can more easily access and inspect the status of the short net, promptly identify and handle potential problems, reducing downtime and maintenance costs caused by failures.
[0044] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the material of the cross arm 1 is Q235B.
[0045] Q235B steel has high yield strength and tensile strength, can withstand larger working load, while maintaining good impact resistance. This high strength characteristic makes the cross arm 1 in the bearing gravity and other external forces can remain stable, not easy to deformation or fracture. In addition, Q235B steel also has good toughness, can absorb energy when impacted, thereby protecting equipment and personnel safety.
[0046] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the front end of the cross arm 1 is provided with an electrode hole and a conductive copper tile;
[0047] The secondary short net 5 connects the conductive copper tile at the front end of the cross arm 1 through the water-cooled cable 3;
[0048] The electrode hole is provided with an electrode.
[0049] The conductive copper tile is directly provided at the front end of the cross arm 1 and connected with the secondary short net 5 through the water-cooled cable 3, greatly shortening the transmission path of the current. Reduce the loss of current in the transmission process, improve the efficiency of electric energy utilization. The conductive copper tile as an excellent conductor has a lower resistivity, which can further reduce the resistance and power loss in the process of current transmission.
[0050] The electrode is connected with the conductive copper tile through the electrode hole, which can quickly respond to current input and realize efficient heating. Improve the heating efficiency and intensity in the smelting process, and speed up the smelting speed. The combination design of the water-cooled cable 3 and the conductive copper tile ensures the stable supply of current. Stable current supply helps to maintain the temperature stability in the smelting process, improve the smelting quality and efficiency. When the current is too large or the equipment is overheated, the water-cooled cable 3 can quickly dissipate heat to prevent equipment damage or safety accidents such as fire.
[0051] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the weight of the electrode ranges from 4.5 to 5.5 tons.
[0052] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the offset of the electrode ranges from 100 to 200 mm.
[0053] The offset of the electrode in the electrode hole can adjust the discharge gap, so that the discharge is more uniform and stable, reducing the occurrence of adverse discharge phenomena such as side secondary discharge and short circuit.
[0054] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3The lifting column 2 supports the furnace cover 4 through a vertical plunger oil cylinder.
[0055] The lifting column 2 is arranged at the edge of the furnace cover 4 and is supported by an upper vertical plunger oil cylinder to realize the lifting action.
[0056] The vertical plunger oil cylinder serves as the lifting power source, with compact structure and small footprint, suitable for limited space. The plunger oil cylinder is a single-acting oil cylinder, mainly relying on hydraulic pressure to realize one-way motion, and its return action usually relies on gravity or other external force. In this design, the vertical plunger oil cylinder can realize the return action through the gravity of the furnace cover 4 or other return mechanisms.
[0057] The lifting column 2 is arranged at the edge of the furnace cover 4, which can maximize the use of the space around the furnace cover 4 and reduce the occupation of the space above the furnace cover 4. The connection point of the column and the furnace cover 4 is usually designed to be strong to ensure the stability and safety during lifting.
[0058] Powered by a hydraulic system, the vertical plunger oil cylinder receives hydraulic pressure and generates thrust to drive the lifting column 2 to rise or fall. The pressure and flow of the hydraulic system can be adjusted by control valves to realize precise control of the lifting speed.
[0059] The lifting column 2 is arranged at the edge of the furnace cover 4, effectively reducing the occupation of the space above the furnace cover 4 and providing more space for the arrangement of other equipment. The solid design of the vertical plunger oil cylinder and the lifting column 2, as well as the use of synchronous control mechanisms, ensures the stability and safety of the furnace cover 4 during lifting. The vertical plunger oil cylinder and the lifting column 2 are usually designed to be easily disassembled and replaced, facilitating the maintenance and repair of the equipment.
[0060] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3 , the maximum cooling water volume is 30-40 cubic meters.
[0061] The specific implementation steps of the utility model are as follows.
[0062] The secondary short net 5 and the water-cooled cable 3 structure form suitable current density are selected; the electrode, the cross arm 1 and other condition parameters are determined, the maximum cooling water volume, the load volume and the like are calculated; the water pipe diameter is calculated and determined, the pipeline path is optimized, the flow velocity and the flow volume are ensured; the material selection is analyzed, the optimal material is determined; the structure drawing is designed, the machining and the pipeline blanking and welding are carried out, the forming is assembled, the pressure test is carried out; the lifting and water passing test is carried out. The structure improvement of the new type conductive cross arm 1, the material reselection, the cooling water flow volume checking calculation and the adoption of the reasonable use and maintenance method have been implemented on the carbonization furnace of Pangang Polytitan Technology Company. At present, the new type conductive lifting cross arm 1 meets the actual furnace condition requirements on site, not only guarantees the continuous and stable operation of the carbonization furnace, but also provides effective support for various technical and economic indexes required by the industrialization construction, is favorable for the steady promotion of the industrialization construction work.
[0063] The utility model discloses a new type conductive cross arm 1, which can effectively solve the problems of electrode cross arm 1 arrangement and power loss, and the solution is divided into two stages.
[0064] The first stage: the traditional cross arm 1 condition is explained, please refer to Figure 1 And Figure 2 Figure 3 Figure 4 Figure 5 .
[0065] Generally, large-scale electric furnaces and electric furnaces generally adopt the electrode holding form, and part of the electric heating furnace adopts the structure form of short net plus cross arm 1. The structure form of short net plus cross arm 1 is usually arranged on the same side horizontally due to the restriction of the installation space of the transformer, the outgoing line end of the transformer is connected by the secondary short net 5, the middle part is connected by the water-cooled cable 3, and the lifting requirement of the cross arm 1 is met. After the water-cooled cable 3 is connected to the conductive cross arm 1, the cross arm 1 is connected to the electrode holder, the electrode is clamped and powered to heat.
[0066] The cross arm system of this structure form is usually long in manufacturing, and the core diameter is required to be small during arrangement, which is not suitable for large-scale electric furnaces. At the same time, the traditional conductive cross arm 1 needs to meet the large current passing, and the material requirement is generally selected as T2, the copper content is > 99.90%, and the manufacturing process requirement and the insulation performance are required to be high. In the actual operation process, because the cross arm 1 is too long, the power loss is also large, and the actual operation cost is increased.
[0067] The second stage: the material selection and manufacturing of the new type cross arm 1.
[0068] The new type of cross arm 1 is improved from the overall arrangement, considering that the three-phase transformer is arranged in star type, the secondary short net 5 can be extended and hung by insulation to the upper part of the carbonization furnace, so that the length of the water-cooled cable 3 can be effectively shortened. The lifting column 2 is arranged at the edge of the furnace cover 4 and is supported by the upper vertical plunger oil cylinder to realize the lifting action. The cross arm 1 is connected with the lifting column 2 and is designed with reliable insulation, because no large current passes through, the material Q235B can be selected, the inside is cooled by water, and the cross arm 1 only plays a clamping and lifting role. The secondary short net 5 is directly connected with the conductive copper tile at the front end of the cross arm 1 through the water-cooled cable 3, the current does not pass through the cross arm 1, the power supply path is shortened, and the electrode is directly acted on.
[0069] The production of the new type of cross arm system needs to calculate the weight of the electrode and the offset in the electrode hole, determine the cooling condition parameters, mainly the water quantity, the pipe diameter, the pipe route and the like, and finally the professional manufacturing plant is used for customization.
