[0042] As described in the background technology, in the related art, open roasting furnaces are widely used in the roasting process of cathodes in aluminum electrolysis cells. Its design and structure are intended to ensure the uniformity and efficiency of the roasting process, thereby improving the quality and service life of the cathodes. However, this open roasting furnace also has some significant disadvantages in actual operation.

[0043] First, the open design makes the loading and unloading process relatively convenient, and the operator can directly observe and adjust the temperature during the roasting process. However, this open structure also causes heat to be easily lost, and the energy utilization efficiency is low. In addition, heat loss may cause uneven temperature during the roasting process, affecting the roasting quality of the cathode. Secondly, although the open design is easy to operate, it also increases the complexity of the operating environment. The smoke and high-temperature gases generated during the roasting process are easy to diffuse into the working environment, posing a potential threat to the personal safety of the operator.

[0044] In general, open roasting furnaces have the advantages of easy loading, unloading and temperature adjustment during the roasting process. However, its open structure also brings problems such as heat loss, low energy efficiency, environmental pollution and complex maintenance. In addition, it increases the risk of operators being exposed to high temperatures and harmful gases, and there are certain safety hazards, which affect the walking and operation of personnel. Personnel may be at risk of heat stroke, and the safety of the working environment cannot be effectively guaranteed. Additional safety measures need to be taken to protect operators.

[0045] In view of this, the embodiment of the present application provides a furnace loading and unloading platform, which includes a support frame and a plurality of cover plate nets. The support frame is movably supported on the top of the furnace chamber group. The support frame is surrounded by a plurality of windows arranged in sequence, so that each window corresponds to each furnace chamber in the furnace chamber group. A plurality of cover plate nets are detachably mounted on the support frame, and each cover plate net is covered in the window. In this way, the support frame provides a stable platform to ensure that the platform will not tilt or move during the furnace loading and unloading process, thereby ensuring the safety and stability of the operation. Each cover plate net is detachably mounted on the support frame, and each cover plate net is covered in each window of the support frame, so that the cover plate net can be disassembled and replaced as needed, which is convenient for cleaning and maintenance. At the same time, the cover plate net can also be moved and adjusted according to different operation requirements. Since the windows of the support frame correspond to the furnace chambers one by one, the operator can directly perform the furnace loading and unloading operation through the windows of the support frame, which is convenient for the operator to observe the situation in the furnace chamber through the holes of the cover plate net, reducing unnecessary movement and operation steps, and can also play a protective role to prevent materials or tools from falling into the furnace chamber during operation, thereby improving work efficiency. Prevent the high-temperature gas in the furnace room from directly contacting the operator, ensure safe operation, and allow personnel to carry out work safely on the platform at the top of the furnace room.

[0046] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0047] The present application provides a furnace loading and unloading platform, which is suitable for an open roasting furnace. The open roasting furnace is, for example, an aluminum cathode roasting furnace, that is, a roasting furnace used to roast the cathode of an aluminum electrolytic cell. The open roasting furnace is usually arranged with multiple furnace chambers on a large site, and the multiple furnace chambers can be arranged in an array in the form of a furnace chamber group. A furnace chamber group can include multiple furnace chambers arranged in sequence, and adjacent furnace chambers are separated by a fire channel wall.

[0048] Figure 1This is a schematic diagram of the layout of the roasting furnace provided in the embodiment of the present application. Figure 1 As shown in the figure, a schematic diagram of the plan layout of an open roasting furnace 2 is illustrated. The open roasting furnace 2 has a total of 36 furnace chamber groups, 18 of which are arranged along the X direction shown in the figure, and each furnace chamber includes 2 furnace chamber groups arranged along the Y direction in the figure. In each furnace chamber group, adjacent furnace chambers are separated by a fire channel wall.

[0049] Figure 2 This is a cross-sectional structural diagram of the fire channel wall 22 provided in the embodiment of the present application. Figure 2 As shown, the cross-sectional structure of the fire channel wall 22 between adjacent furnace chambers is shown in the figure. The interior of the fire channel wall 22 is a hollow structure, and a plurality of partitions can be arranged inside the fire channel wall 22, and each partition can be arranged in sequence along the length direction of the fire channel wall 22. In addition, along the arrangement direction of the partitions, the partitions can be arranged alternately up and down. In other words, of two adjacent partitions, one partition is connected to the top of the fire channel wall 22, and there is a gap between the partition and the bottom of the fire channel wall 22. The other partition is connected to the bottom of the fire channel wall 22, and there is a gap between the partition and the top of the fire channel wall 22.

[0050] Figure 2 The direction of the middle arrow indicates the inflow direction of the high-temperature natural gas. By setting the partitions in the fire channel wall 22 in an alternating manner, the high-temperature natural gas flows along a curved route in the fire channel wall 22, thereby ensuring the flow of the high-temperature natural gas in the lower space of the fire channel wall 22. In this way, the high-temperature natural gas is prevented from being densely distributed and gathered in the upper part of the fire channel wall, and the heat is evenly and fully distributed in various parts of the fire channel wall 22, which can ensure that the furnace chamber is heated evenly and ensure the roasting effect of the furnace chamber on the internal materials.

[0051] Continue to refer to Figure 2 The open roasting furnace 2 may further include a connecting fire channel 23, and both ends of each fire channel wall 22 may be connected to the connecting fire channel 23. High-temperature natural gas is transported from the connecting fire channel 23 at one end of the fire channel wall 22 into the fire channel wall 22, and then flows out from the connecting fire channel 23 at the other end of the fire channel wall 22. The principle of the connecting fire channel is to design and control the airflow and pressure difference between the fire channels so that fresh air can effectively enter the roasting area to ensure that heat is transferred to the roasting furnace, thereby ensuring the efficiency and safety of the roasting process.

[0052] Figure 3 This is a schematic diagram of the structure of the main platform in the furnace loading and unloading platform provided in the embodiment of the present application. Figure 3As shown, the embodiment of the present application provides a furnace loading and unloading platform 1, which can be used in an open type roasting furnace. For example, the furnace loading and unloading platform 1 can be used in an open type roasting furnace for aluminum cathodes. The furnace loading and unloading platform 1 is placed on the top of the furnace chamber group in a movable manner. By moving the furnace loading and unloading platform 1 between different furnace chamber groups, the furnace loading and unloading platform 1 can help operators complete operations on all furnace chamber groups.

[0053] Combination Figure 1 and Figure 3 As shown, taking the application of the furnace loading and unloading platform 1 in the aforementioned 36-chamber open roasting furnace as an example, one furnace loading and unloading platform 1 corresponds to one furnace chamber group, and the furnace loading and unloading platform 1 starts from the position of the furnace chamber group No. 1 and goes along Figure 1 Move in the opposite direction of the x direction shown in the figure to the position of the No. 2 furnace group, and then move to the position of the No. 18 furnace group in this direction. Figure 1 Move to the position of furnace chamber group No. 19 in the y direction as shown in Figure 1 The furnace loading platform 1 moves in the X direction shown in the figure to the position of the furnace chamber group No. 20, until it moves in the X direction to the position of the furnace chamber group No. 36, so that the furnace loading platform 1 can go around the 36-chamber open roasting furnace.

[0054] Specifically, the furnace loading and unloading platform 1 includes a main platform, which can be supported on the top of the furnace chamber group 20, and the main platform completely overlaps with the contour of the furnace chamber group 20. The main platform provides a base for operators to stand and walk, so that the operators can stand and walk above the furnace chamber group 20.

[0055] The main platform includes a support frame 11 and a cover plate net 12. The support frame 11 is the basic support structure of the furnace loading platform 1, and the support frame 11 is movably supported on the top of the furnace chamber group 20. A plurality of cover plate nets 12 are detachably installed on the support frame 11. The support frame 11 and the cover plate net 12 constitute the main platform of the furnace loading platform 1.

[0056] The support frame 11 is the main support structure of the main platform. The support frame 11 is surrounded by a plurality of windows 110 arranged in sequence to realize a stable support structure, and presents a plurality of rectangular structures, so that the furnace loading and unloading platform 1 can carry different components and materials. Each window 110 corresponds to each furnace chamber in the furnace chamber group 20. The support frame 11 provides a supporting force to the cover plate net 12, and the cover plate net 12 covers the window 110 to prevent materials from falling or foreign debris from entering the furnace chamber. At the same time, it can be easily disassembled when necessary to load or remove materials.

[0057] Figure 4 This is a schematic diagram of the structure of the support frame in the main platform provided in the embodiment of the present application. Figure 4As shown, the support frame 11 includes an outer frame 111 and a plurality of support beams 112. The outer frame 111 is arranged around the outer periphery of the furnace chamber group 20, and each of the support beams 112 is sequentially connected to the outer frame 111 at intervals. The support beams 112 are arranged in parallel in the outer frame 111, thereby ensuring that the overall structure of the support frame 11 is stable and the force is uniform. In addition, the support frame 11 is made of 45 steel material as a whole, which has high strength and toughness. The overall frame is rectangular and stable, thereby ensuring the safety of personnel operations.

[0058] Figure 5 This is a diagram of the decomposition structure of the main platform provided in the embodiment of the present application. Figure 5 As shown, in order to show the internal structure of the furnace loading platform 1, the arrows in the figure are used to illustrate that a supporting frame 11 of the furnace loading platform 1 needs to be installed with multiple cover nets 12. The outer frame 111 and the supporting beams 112 together enclose the windows 110, and the supporting beams 112 are correspondingly arranged at the top of the fire channel wall between the adjacent furnace chambers. The cover net 12 is supported by the outer frame 111 and the three supporting beams 112 as the main body to ensure the stability and reliability of the furnace loading platform 1.

[0059] Figure 6 A schematic diagram of the structure of the first lifting ear / second lifting ear provided in an embodiment of the present application. Figure 6 Figure A refers to the front view of the first lifting ear / the second lifting ear, Figure B refers to the cross-sectional view of the first lifting ear / the second lifting ear along the AA axis, and Figure C refers to the top view of the first lifting ear / the second lifting ear.

[0060] Reference Figure 6 As shown, the outer frame 111 is provided with a first lifting lug 11a, and the first lifting lug 11a is used for a lifting device to lift the support frame 11 for installation and disassembly, thereby improving work efficiency. The first lifting lug 11a is integrated with the outer frame 111 by welding. Exemplarily, the main body of the first lifting lug 11a is usually annular to provide a stable connection point. The annular design can evenly distribute the load. Similarly, a second lifting lug 12a is also provided at the edge of the cover net 12, and the second lifting lug is used for a lifting device to lift the cover net 12 for installation and disassembly, thereby improving work efficiency. The structural form of the second lifting lug 12a can be similar to that of the first lifting lug 11a, which will not be repeated here.

[0061] Figure 7 The structural diagram of the cover plate net in the furnace loading and unloading platform provided in the embodiment of the present application. Figure 7 As shown, in some embodiments, a receiving groove 120 is opened at the edge of the cover mesh 12, and the second ear 12a is movably connected in the receiving groove 120. The second ear 12a can move flexibly and can rotate 90° in the vertical direction.

[0062] When the main platform is placed on the top of the furnace chamber group 20 and the operator is working on the main platform, the second lifting ear 12a can be hidden in the accommodating groove 120. At this time, the second lifting ear 12a is embedded in the cover plate net 12, and the surface of the cover plate net 12 remains flat, so that the operator will not be bumped or tripped due to the protrusion of the second lifting ear 12a on the surface of the cover plate net 12, thereby improving the safety of operation.

[0063] When the cover net 12 needs to be moved, the second lifting lug 12 can be turned upward so that the second lifting lug 12a passes through the receiving groove 120 and extends above the cover net 12. At this time, the operator can use the second lifting lug 12 to freely lift and place the cover net 12.

[0064] Figure 8 This is a schematic diagram of the structure of the safety column provided in the embodiment of the present application. Figure 8 As shown, the support frame 11 is equipped with a protective device 13. The protective device is detachably mounted on the support frame, and when the operator stands or walks on the main platform, the operator can connect a part of the body of the operator to the protective device. The protective device limits the operator's moving area to a certain range to prevent the operator from falling from the main platform and ensure the operator's personal safety.

[0065] The protective device 13 includes a safety column 131 and a fall arrester (not shown in the figure). The bottom of the safety column 131 is slightly narrow, and the bottom end is inserted into the mounting hole set on the support frame 11. The top of the safety column 131 is connected to a mounting ring 132. One end of the connector is connected to the mounting ring 132, and the connector, such as the lock of the safety hook, is opened and inserted into the opening of the mounting ring 132. Make sure that the connector fully enters the mounting ring 132 and there are no obstacles blocking the connection. Close the connector and make sure it is firmly locked on the mounting ring 132. At this point, the connection between the mounting ring 132 and the connector has been completed, and then the other end of the connector is connected to the fall arrester. Open the other end of the connector, and then insert the connection point of the fall arrester (such as a self-locking hook or the end of the connecting rope) into the connector. Make sure that the connection point of the fall arrester fully enters the connector and there are no obstacles blocking the connection. Close the connector and make sure it is firmly locked on the fall arrester. At this point, the connection between the mounting ring 132, the connector and the fall arrester has been completed, but in order to ensure the safety and reliability of the connection, a series of safety checks are required. The operator wears the fall arrester and hangs the fall arrester into the mounting ring to perform the operation safely.

[0066] The support frame 11 is provided with a plurality of mounting holes, each of which is arranged at intervals along the circumference of the support frame 11, so as to facilitate the removal of the safety column 131. Specifically, the mounting holes can be provided on the outer frame 111 of the support frame 11. The mounting holes are arranged at intervals along the circumference of the outer frame 111, so as to facilitate the insertion of the safety column 131 at different positions, so that the operator can stand at different positions.

[0067] Fig. 9 This is a schematic diagram of the structure of the edge platform of the furnace loading and unloading platform provided in the embodiment of the present application. Fig. 9 As shown, the furnace loading platform 1 also includes an adjacent platform 14, which is movably arranged on one side of the main platform. The adjacent platform 14 is arranged side by side and close to the main platform. The furnace chamber group 20 corresponding to the main platform is the furnace chamber group 20 in operation, and the adjacent platform 14 can be supported on the top of the furnace chamber group 20 adjacent to the furnace chamber group 20 in operation. Exemplarily, the adjacent furnace chamber group 20 can be an empty furnace chamber that is not in operation.

[0068] The side platform 14 can be used as a passage for operators to go up and down the main platform, ensuring the safety of operators during the process of loading and unloading the furnace. In addition, the side platform 14 is used for operators to stand or rest, or can also be used to place working tools, etc. The side platform 14 provides a flat and spacious working area, so that operators can conveniently perform maintenance, inspection and operation of the roasting furnace without having to worry about working in a narrow or unstable environment.

[0069] Exemplarily, a safety guardrail is installed on the side of the side platform 14 away from the main platform. Such a setting can effectively prevent operators from falling in high temperature and high altitude environments and ensure their personal safety. As mentioned above, the furnace loading and unloading platform can be moved to place the furnace loading and unloading platform on the top of different furnace chamber groups 20. The following is an explanation of the hoisting process of the furnace loading and unloading platform.

[0070] In order to ensure the safety and efficiency of the operation of the open roasting furnace during loading, unloading and maintenance, a hoist can be used to lift and move the loading and unloading platform to place it on the top of the corresponding furnace chamber group 20.

[0071] First, use a crane (e.g., a double-beam bridge crane) and an iron chain to lift the support frame 11 to the top of the corresponding furnace chamber group 20 through the first lifting lug 11a on the support frame. The operator should carefully check the state of the lifting lug and the iron chain to ensure that there is no damage or wear, and then firmly connect the iron chain to the first lifting lug 11a, start the crane, and slowly lift the support frame to ensure that the support frame is smoothly lifted and moved to the designated position.

[0072] Next, the cover net 12 needs to be lifted to cover the upper part of the roasting furnace to ensure the sealing of the furnace chamber 21 and the safety of operation. The cover net 12 is usually made of high temperature resistant material and has good heat resistance and corrosion resistance. Use a double-beam bridge crane and an iron chain to lift the cover net 12 to the inside of the platform hole through the lifting lugs, leaving a gap for subsequent operations. The operator should ensure that the cover net 12 is not damaged and the structure is intact, then connect the iron chain to the lifting lug of the cover net 12, start the crane, and slowly lift the cover net 12 to ensure that it is lifted smoothly and moved to the designated position, and ensure that the four material boxes on the upper part of the furnace chamber are fully covered.

[0073] After the cover mesh 12 is laid, the safety column 131 needs to be installed to ensure the safety of the operator. The safety column is inserted into the hole of the furnace platform, and the operator hangs the fall arrester into the mounting ring 132 to ensure safety when working at height. The safety column 131 is usually made of high-strength steel and has good load-bearing capacity and stability. The operator should ensure that the safety column 131 is not damaged and the structure is intact, and then insert the safety column 131 into the hole of the furnace platform 1 in turn to ensure that the column is stable. Then, the operator hangs the fall arrester into the mounting ring 132 to ensure that the connection is firm, and conducts a safety check to ensure that all safety devices are correctly installed before working at height.

[0074] The side platform 14 is lifted to one side of the furnace loading platform by the first lifting lug 11a, and a safety guardrail is installed. The safety guardrail is placed at the edge perpendicular to the furnace loading platform 1 to prevent personnel from falling due to the lifting lug being too high. The side platform 14 is usually made of high-strength steel, has good load-bearing capacity and stability, and can carry heavy objects. The operator should ensure that the side platform 14 is not damaged and the structure is intact during the operation. Then connect the iron chain to the lifting lug of the side platform 14, start the crane, slowly lift the side platform, ensure that it is smoothly raised and moved to the designated position, ensure that the platform is firmly placed and install the safety guardrail, and ensure the safety of the operator's up and down passages.

[0075] After the loading or unloading operation is completed, the platform needs to be hoisted to the location of the next operation. Use a double-beam bridge crane to lift the platform by the lifting lugs to ensure the continuity and safety of the operation. The operator should ensure that the platform is not damaged and the structure is intact, then connect the iron chain to the lifting lug of the platform, start the crane, slowly lift the platform, ensure it is smoothly raised and moved to the location of the next operation, and ensure that the platform is firmly placed. During the loading, unloading and maintenance of the roasting furnace, repeat the above steps to operate all the furnace chambers of the roasting furnace, solve the problem of personnel falling from heights, and ensure the safety of personnel.

[0076] By hoisting the loading and unloading platform according to the hoisting process, the operating efficiency and safety of the operators can be ensured during the loading, unloading and maintenance of the open roasting furnace. The correct use and operation of the main platform, the side platform and the protective device not only improves the production efficiency, but also effectively prevents the occurrence of safety accidents such as the operator falling from a height. By strictly following the above steps and processes, the safe and efficient operation of the open roasting furnace can be ensured.
