Description

Graphitization system

Technical Field

The invention relates to the technical field of graphitization, in particular to a graphitization system.

Background

Graphite materials are irreplaceable conductive materials which can be used at high temperature, a graphitization process is an essential process in the production of artificial graphite, and high temperature (above 2500 ℃) is the only way for manufacturing the artificial graphite. Common graphitization processes include Acheson furnace, inner series furnace, and box furnace. The Acheson furnace is filled with resistance materials to heat the crucible by electrifying, and then the temperature of the negative electrode powder in the crucible is raised to be more than 2800 ℃, and the Acheson furnace has the advantages of wide application range, high yield, high flexibility and the like, but has the defects of long production period, high energy consumption, uneven temperature of each point in the furnace and the like.

Four core processes which need to be carried out on a graphitization furnace in Acheson graphitization production are charging, power transmission, cooling and discharging. In the traditional process, a graphitization furnace is fixed, and the furnace is a station for charging, power transmission, cooling, discharging and other processes. In order to solve the problem that the time consumption of the cooling process is too large compared with that of other processes, a plurality of furnaces are required to be arranged for alternate operation. Therefore, each process of charging, power transmission and discharging must be switched back and forth between a plurality of stations, when the stations are more, on one hand, the consumption of copper and aluminum rows for power transmission is very large, and the construction cost is increased, on the other hand, when mechanical equipment (such as charging equipment, material suction equipment or hoisting equipment and the like) needs to be arranged on each station or the mechanical equipment is shared by the stations, the construction cost of the production line is further increased and a large safety risk exists due to frequent transportation of the equipment between the stations and the like, and when any station breaks down or breaks down, the normal production of other stations and the personal safety of nearby operators are easily affected, and the stability and fault tolerance are low. And has higher environmental protection cost due to more stations needing heating. In view of the above problems, although a patent with application number CN202110176780.5 (published as 2021, 5/18) discloses a mobile graphitization furnace system and a power supply device thereof in the prior art, the construction cost and the use cost of a graphitization operation system are reduced to some extent by designing a rail mobile graphitization furnace so that a furnace body is transferred between each process station.

However, due to the limitation of the moving mode of the graphitization furnace, the unreasonable design and arrangement of the working stations of each process still causes the low graphitization production efficiency, and the invention aims to provide the graphitization system with low construction cost and high working efficiency.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments; the technical features designed in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other; all other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be noted that all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs, and are not to be construed as limiting the present invention; it will be further understood that terms used herein should be interpreted as having a meaning that is consistent with their meaning in the context of this specification and the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

The following description will be made by specific examples.

In traditional Acheson furnace graphitizing production, a plurality of graphitizing furnaces are arranged, and each graphitizing furnace is used as an integrated station of four core processes of graphitizing production, namely furnace charging, power transmission, cooling, furnace discharging and the like. In the conventional graphitization process shown in fig. 1, the graphitization system increases the number of graphitization furnace stations to increase the throughput. But because integrated more processes on every station, when the station quantity is more, in order to reduce cost, generally can adopt the mode of the special device of peak shifting sharing process, need not every station and all be equipped with complete equipment, saved the cost but also lead to having a large amount of problems simultaneously:

for example, the transformer and each graphitizing furnace are connected through the copper-aluminum row to supply power, and as the occupation of land of a plurality of furnaces is large, as shown in the schematic power supply structure diagram of fig. 2, the length of the copper-aluminum row depends on the furnace farthest from the transformer, so that the consumption of the copper-aluminum row is very large, the construction cost is high, and meanwhile, the loss of electric energy lines is high.

In the core processes such as charging, power transmission, cooling, discharging and the like, as shown in fig. 3, the relationship between the processes and the stations is 4 to n, that is, each process needs to be switched among n stations, and each station needs to perform 4 processes. The mode requires that equipment, materials and personnel related to each process (particularly charging and discharging processes) need to frequently move in a long distance, and n stations are concentrated in the same space, so that the process independence is poor, mutual avoidance and waiting (for example, when a travelling crane is lifting materials, another travelling crane cannot pass through) must be considered when public facilities (such as travelling cranes, material stacking sites and the like) are used, and the production efficiency is limited; heavy objects (such as a crucible, a template, a grab bucket, a flue gas collecting cover and the like) lifted by a public travelling crane frequently pass above a station which is transmitting power, and the device is unsafe; the energy, time and labor consumed in the transportation operation without increasing the value are more, and the operation cost is high; when any station breaks down or has accidents, such as furnace spraying and the like, the normal production of other stations and the personal safety of nearby operators are easily influenced; smoke and dust are discharged seriously without structures, and the working environment is severe; the difficulty of realizing mechanization and automation is high, and the construction cost of multi-station and multi-process general equipment (such as a loading and material-sucking multifunctional travelling crane) and a matched workshop is high.

In addition, the conventional graphitization system has a problem that a fixed flue gas collecting cover cannot be built on the top of the furnace in order not to affect the operation of other processes, and only a movable flue gas collecting cover can be used for switching among stations. The smoke collecting pipe of the environmental protection system is provided with a plurality of interfaces connected with the smoke collecting cover. The flue gas collecting pipe of this kind of configuration is long, and fan power is big, and the energy consumption is high, and the pipeline valve is big again and many and leak easily. The mechanization and automation degree of auxiliary procedures such as crucible loading and crucible unloading is low, the labor intensity is high, and the labor consumption is high.

In order to solve the above problems, the present invention provides a graphitization system including

The furnace charging area 20 is provided with at least one furnace charging station 21, and the furnace charging station 21 is provided with a furnace charging device for filling furnace charge and a crucible into the graphitizing furnace 10;

the number of the cooling stations 41 is greater than or equal to the number of the charging stations 21, the number of the power transmission stations 31 or the number of the tapping stations 51.

In specific implementation, as shown in fig. 4, the graphitization system provided by the present invention is mainly divided into a charging area 20, a power transmission area 30, a cooling area 40, and a discharging area 5, and further provided with a plurality of graphitization furnaces 10, wherein the graphitization furnaces 10 are movable, and a transfer drive unit 11 is provided at the bottom of each graphitization furnace 10 to drive each graphitization furnace 10 to move, so that each graphitization furnace 10 can sequentially pass through a charging station 21 provided in the charging area 20, a power transmission station 31 provided in the power transmission area 30, a cooling station 41 provided in the cooling area 40, and a discharging station provided in the discharging area 50, thereby realizing graphitization full core process operation for each graphitization furnace 10. Each station only executes the exclusive process of the area, and each process area can be provided with a plurality of corresponding stations according to the actual situation, and particularly, the number of the cooling stations 41 is not less than the number of the charging stations 21, not less than the number of the power transmission stations 31 and not less than the number of the discharging stations 51, considering that the cooling process executed by the cooling station 41 takes longer time than other processes (generally, the time taken by the charging process, the power transmission process and the discharging process is 1-5 days, and the time taken by the cooling process is 10-40 days).

Preferably, in some embodiments, the selection of the number of stations is as set forth in the following table one:

Preferably, the number of graphitization furnaces 10 should be greater than the number of core processes to avoid complete idling of the stations for some processes.

It should be understood that the above is a preferred embodiment of the adjusting device, but not limited thereto, and the adjusting device further employs a five-axis control platform or a combination of a three-axis control platform and a rotation motor, etc. for controlling the elevation, horizontal translation and rotation of the graphitization furnace 10 and leveling control of the graphitization furnace 10.

Preferably, in some embodiments, the power transmission station 31 of the power transmission area 30 is arranged in an independent compartment different from other stations, the independent compartment is surrounded by fire-resistant partition walls, and a safe distance should be arranged between the independent compartment and other stations to isolate the power transmission station 31 from other stations, and in addition, a flue gas collection device is arranged at the top of the independent compartment, and flue gas generated during electric heating is guided into an environmental protection system including a flue gas purifier and other equipment through the flue gas collection device.

Second embodiment: the graphitization system is provided with two rectifier transformers 32, six power transmission stations 31, three tapping stations 51, three charging stations 21, fifteen cooling stations 41, one maintenance station 60, two crucible loading stations 81, two crushing and screening stations 92, two crucible tapping stations 91, one environment-friendly station and twenty graphitization furnaces 10, and the transfer driving part 11 is carried by 1 matched power transport vehicle.

The third embodiment: the graphitization system is provided with three rectifier transformers 32, six power transmission stations 31, five furnace discharging stations 41, three furnace charging stations 21, twenty-four cooling stations 41, two maintenance stations 60, two crucible charging stations 81, two crushing and screening stations 92, three crucible discharging stations 91, an environment-friendly station and thirty-six graphitization furnaces 10 in total, and the transfer driving part 11 is carried by 2 matched power transport vehicles.

In actual use, as shown in fig. 4 and 6, after raw materials are loaded into the crucible by the automatic crucible loading device, the loaded crucible is transported to the furnace loading station 21 through special logistics equipment and is stacked in order. The charging station 21 uses a special lifting appliance to lift the crucibles into the graphitization furnace 10 in batches, and uses a discharging device with a telescopic pipe to load fresh furnace burden and recycled furnace burden into the gaps between the crucibles in the graphitization furnace 10. After charging, the furnace moves to the power transmission station 31 and is butted with a rectifier transformer 32 through a copper-aluminum row 33. The power transmission station 31 is isolated from all other stations and is provided with a fixed flue gas collection system. After the power transmission starts, the flue gas collecting system collects the flue gas discharged by the graphitization furnace 10 and then sends the collected flue gas to the environmental protection system. After the end of power transmission, the graphitization furnace 10 moves from the power transmission station 31 to the cooling station 41. The cooling station 41 uses a water cooling device and an air cooling device to cool one or more of the furnace end, the furnace wall, the furnace bottom and the furnace charge surface. After the cooling is completed, the graphitization furnace 10 is moved to the tapping station 51. The discharging station 51 adopts a material sucking device with a telescopic pipe to cool the sucked furnace charge and then convey the furnace charge to a crushing and screening station 92, and adopts a special lifting appliance to lift the crucibles out of the graphitization furnace 10 in batches and stack the crucibles in order.

After the crucible discharging is finished, the finished empty crucible is transported to a crucible loading station 90 through special logistics equipment to be continuously used, and the damaged crucible is transported to a crushing and screening station 92. The crushing and screening station 92 crushes and screens the furnace charge and the damaged crucible, and then one part of the furnace charge is recycled as the furnace charge, and the other part of the furnace charge is bagged as a graphitization byproduct.

Because only a plurality of power transmission stations of the power transmission area need to carry out the power transmission process, the length of the copper-aluminum bar during construction can be greatly reduced, and the construction cost is saved. The stations of all the processes operate independently, the required equipment only needs to be provided with the special equipment of the same type, and compared with the prior art that equipment with different processes is arranged on each station or equipment with different processes operates alternately, the method has the advantages of lower construction cost and higher operation efficiency. Meanwhile, the number of stations consuming long time, such as cooling stations, is relatively more, so that the working efficiency of each process is balanced, certain processes are prevented from being blocked, and the production efficiency is improved.

In addition, it will be appreciated by those skilled in the art that, although there may be many problems with the prior art, each embodiment or aspect of the present invention may be improved only in one or several respects, without necessarily simultaneously solving all the technical problems listed in the prior art or in the background. It will be understood by those skilled in the art that nothing in a claim should be taken as a limitation on that claim.
