It should be further understood that the term "and / or" as used in this disclosure and the claims refers to any and all possible combinations of one or more of the associated listed items, including and including these combinations.
[0027] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
[0028] See also Figure 1 and Figure 2 ,in Figure 1 A schematic diagram showing the structural principle of a material moving assembly according to some embodiments of the present disclosure is shown; Figure 2 A schematic top view of a drive mechanism according to some embodiments of the present disclosure is shown. In some embodiments of the present disclosure, a crane for a graphitization furnace is provided, which may include a frame 90, a drive mechanism 50, and a material transfer assembly 10. The drive mechanism 50 is disposed on the frame 90 and may include a first track 501 disposed along the length of the frame 90.
[0029] See also Figure 3In some embodiments, the material transfer assembly 10 may include a material receiving device 100, a first dust collector 200, a cooler 300, and a second dust collector 400. The two sides of the first dust collector 200 may be connected to the material receiving device 100 and the cooler 300, respectively, and the cooler 300 may be further connected to the second dust collector 400. Thus, the material receiving device 100, the first dust collector 200, the cooler 300, and the second dust collector 400 are connected in sequence, forming a dust removal and cooling path that can be used for gases such as high-temperature flue gas. The material transfer assembly 10 can be fixed to a drive mechanism 50 and driven by the drive mechanism 50 to move along a first track 501, so that the position of the material transfer assembly 10 can be changed by controlling the movement of the drive mechanism 50. The material transfer assembly 10 can move along the first track 501 of the frame 90 to align with, for example, the corresponding material receiving area of the graphitization furnace and the material storage assembly, collect the material in the graphitization furnace, or transfer the collected material to the material receiving area. While taking and placing materials with the help of the material transfer assembly 10, the first dust collector 200, the cooler 300, and the second dust collector 400 connected to the material receiving device 100 can simultaneously perform cooling and dust removal, thereby improving production efficiency.
[0030] The material receiving device 100 may include a material bin 101 and a material receiving pipe 102 connected to the material bin 101. The material receiving pipe 102 is disposed at the bottom of the material bin 101 and is used to discharge the material from the material bin 101 or to draw the material into the material bin 101. The material receiving pipe 102 has a telescopic function, thereby being able to adapt to the need to absorb material at different depths in the graphitization furnace. The cooler 300 may, for example, have a cooling chamber, and a cooling fan or other cooling medium circulation device may be disposed outside the cooling chamber to cool the flue gas and other gases flowing through the cooling chamber of the cooler 300.
[0031] In some embodiments, the first dust collector 200 can be a cyclone dust collector. When the material receiving device 100 draws material from the graphitization furnace, the influx of material may generate high-temperature smoke and dust inside the material bin 101. In this regard, driving the first dust collector 200 can suck smoke and other gases out of the material bin 101, thereby reducing environmental pollution and mitigating safety hazards caused by high temperatures. Furthermore, the air inlet pipe of the first dust collector 200 is connected to the material bin 101, and the exhaust pipe is connected to the cooling chamber; the first dust collector 200 may also have a first ash discharge pipe 201, the conduction of which is controlled by a first ash cleaning valve 202.
[0032] When the device is running, the material receiving device 100 sucks in the material and generates high-temperature flue gas and other gases inside the material bin 101. The high-temperature flue gas and other gases enter the first dust collector 200 through the air inlet of the first dust collector 200 and undergo preliminary dust removal there. The material filtered out during the process is retained in the first dust collector 200, and the flue gas and other gases after preliminary dust removal are guided to the cooler 300 through the exhaust port. Before and after the above work starts or when there is too much material accumulated inside the first dust collector 200, the first ash removal valve 202 can be opened to release the material inside the first dust collector 200; the material is discharged to the outside atmosphere or other parts of the device through the first ash discharge pipe 201.
[0033] In some embodiments, the cooler 300 has a cooling chamber, and the second dust collector 400 may be a bag filter, with its inlet connected to the cooling chamber of the cooler 300. The cooling chamber of the cooler 300 is connected to the inlet of the second dust collector 400 via a second connecting pipe 301, and the second connecting pipe 301 is also provided with a second valve 302 to control the flow of the second dust collector. After the flue gas and other gases are cooled by the cooler 300, they enter the interior of the second dust collector 400 through the inlet and undergo secondary dust removal. The filtered materials are retained in the second dust collector 400 during the process. The second dust collector 400 has a second ash discharge pipe 401, the flow of which is controlled by a second ash cleaning valve 402 provided therein. Before and after the second dust collector 400 is operated, or when excessive material accumulates within it, the second ash cleaning valve 402 can be opened to release the material inside, which is then discharged to the atmosphere through the second ash discharge pipe 401.
[0034] In some embodiments, the second dust collector 400 is connected to an air compressor 403, which can be used to provide positive pressure to the material transfer assembly 10, and can also be used to assist in cleaning the materials inside the second dust collector 400. Specifically, the air compressor 403 provides compressed air to the inside of the second dust collector 400, and when the airflow is blown to the second dust collector 400, the attached dust can be removed. In addition, the second dust collector 400 is connected to a centrifugal fan 404 to provide negative pressure to the material transfer assembly 10, and to form a suction airflow inside the second dust collector 400. The centrifugal fan 404 extracts air from the inside of the second dust collector 400, which can enhance the dust removal effect of the second dust collector 400 on gases such as flue gas.
[0035] In some embodiments, first ash discharge pipe 201 of first dust collector 200 can be connected to the inlet of second dust collector 400 via first connecting pipe 203, and first valve 204 for controlling its conduction is further provided on first connecting pipe 203. In some application scenarios, for high-temperature flue gas or other gas to be removed, first ash removal valve 202 and first valve 204 can be closed, allowing the flue gas or other gas to pass through first dust collector 200, cooler 300, and second dust collector 400 in sequence.
[0036] In some embodiments, the second dust collector 400 further includes a third ash discharge pipe 405 disposed on its side. The third ash discharge pipe 405 is connected to the material receiving pipe 102 and its communication with the material receiving pipe 102 is controlled by the third valve 103. The third ash discharge pipe 405 is also connected to the second ash discharge pipe 401 and its communication with the second ash discharge pipe 401 is controlled by the fourth valve 406.
[0037] In some embodiments, the receiving tube 102 can be telescopic in the vertical direction, so that it can be extended when receiving or discharging materials, and retracted when moving along the frame 90. The telescopic receiving tube 102 can also adapt to work requirements in different occasions. For example, for absorbing materials at a lower position in the graphitization furnace, the receiving tube 102 can be controlled to be appropriately extended; for scenarios where the material transfer assembly 10 and the graphitization furnace are relatively close, the length of the receiving tube 102 can be appropriately shortened. A discharge valve 104 can also be provided on the receiving tube 102 to control the conduction of the receiving tube 102, so that after closing the discharge valve 104, the receiving device 100 can store materials for a long time and open it again when it is needed to discharge materials to the outside world.
[0038] See also Figures 2 to 4 , Figure 3 A schematic side view of an overhead crane for a graphitization furnace according to some embodiments of the present disclosure is shown; Figure 4 A schematic front view of a overhead crane for a graphitizing furnace according to some embodiments of the present disclosure is shown. In some embodiments, the driving mechanism 50 may include a transverse moving mechanism 502, which moves along a first track 501. Furthermore, a second track 504 is provided on the transverse moving mechanism 502, and the driving mechanism 50 also includes a longitudinal moving mechanism 503, which is provided on the transverse moving mechanism 502 and moves along the second track 504. The material moving assembly 10 can be provided on the longitudinal moving mechanism 503, so as to achieve transverse and longitudinal movement relative to the frame 90. In some embodiments, the overhead crane may further include a lifting mechanism 60, which, for example, may be provided on the longitudinal moving mechanism 503, for connecting with the second ash discharge pipe 401 and the material receiving pipe 102, and driving them to move in the vertical direction.
[0039] In some embodiments, the overhead crane further includes a control assembly for controlling the operation of the material moving assembly 10. Furthermore, the control assembly can be mounted on the material moving assembly 10, allowing the user to adjust the operating state of the overhead crane in real time. The control assembly can also be mounted external to the overhead crane, allowing the user to control the operation of the overhead crane from a distance.
[0040] In summary, according to some embodiments of the present disclosure, a crane for a graphitization furnace is provided, which arranges a material assembly on a first rail 501 of a frame 90, and further arranges a material moving assembly 10 on a driving mechanism 50 having a transverse moving mechanism 502 and a longitudinal moving mechanism 503, so that the material moving assembly 10 can move freely to meet the needs of transferring materials to graphitization furnaces at different positions; in addition, a dust removal path is also formed which passes through a material bin 101, a first dust collector 200, a cooler 300, and a second dust collector 400 in sequence, so as to effectively remove dust from high-temperature flue gas and other gases generated during the operation of the crane, which is beneficial to the maintenance of the crane device.
[0041] See also Figure 5 , Figure 5 A schematic top view of a material transfer system for a graphitization furnace according to some embodiments of the present disclosure is shown. Some embodiments of the present disclosure also provide a material transfer system 2000 for a graphitization furnace. The system comprises at least one graphitization furnace 700 and an overhead crane 1000 for a graphitization furnace as described in any of the above embodiments.
