[0024] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.
[0025] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0026] like Figure 1 As shown, at least one embodiment provides a dust collection device for a graphitization furnace, including: an annular tubular chain conveyor 1, a storage silo 2, a discharge mechanism 3, a bag filter 4, and a negative pressure generator 5.
[0027] Specifically, the annular tubular chain conveyor 1 is used to receive and transport materials.
[0028] Specifically, the storage bin 2 is used to receive materials conveyed under positive pressure, and its bottom is connected to the lower pipeline of the annular tubular chain conveyor 1 to transport the materials received in the bin to the annular tubular chain conveyor 1.
[0029] Specifically, such as Figure 1 , Figure 2 As shown, the discharge mechanism 3 is connected to the upper pipeline of the annular tubular chain conveyor 1, and includes: a plurality of discharge pipes 31 connected to the upper pipeline of the annular tubular chain conveyor 1, used to transport the material in the annular tubular chain conveyor 1 to the graphitization furnace.
[0030] Specifically, the bag filter 4 includes a dust collection bin 41 and several suction pipes 42. The lower part of the dust collection bin 41 is connected to the annular tubular chain conveyor 1. One end of the suction pipe 42 extends to the opening of the corresponding discharge pipe 31, and the other end is connected to the middle of the dust collection bin 41.
[0031] Specifically, the negative pressure generator 5 is connected to the upper part of the dust collection bin 41 to absorb dust under negative pressure, and the negative pressure generator 5 is connected to the upper part of the storage bin 2 to depressurize the storage bin 2.
[0032] In this embodiment, a bag filter 4 is used, with the suction pipe 42 of the bag filter 4 extending to the outlet pipe 31. This allows for negative pressure absorption of the dust generated by the material discharged from the outlet pipe 31 into the dust collection bin 41, and the dust in the dust collection bin 41 is directly sent to the annular tubular chain conveyor 1. This not only avoids material loss caused by dust, but also directly sends the collected dust into the annular tubular chain conveyor 1.
[0033] like Figure 1 As shown, in some embodiments, a first rotary valve 410 is provided on the connecting pipeline between the dust collection bin 41 and the annular tubular conveyor 1; a second rotary valve 21 is provided on the connecting pipeline between the storage bin 2 and the annular tubular conveyor 1.
[0034] In this embodiment, a rotary valve is used to avoid the material from being difficult to fall due to negative pressure in the dust collection bin 41 and the storage bin 2.
[0035] like Figure 2 As shown, in some embodiments, the annular tubular chain conveyor 1 is inclined.
[0036] In this embodiment, the inclined annular tubular chain conveyor 1 allows the storage bin 2 and the discharge mechanism to be misaligned, thereby saving installation space.
[0037] In some embodiments, the negative pressure generator 5 is a high-pressure centrifugal fan.
[0038] In this embodiment, the negative pressure generator 5 is connected to the storage bin 2 and the dust collection bin 41 respectively, thereby generating negative pressure in the dust collection bin 41 to absorb dust and depressurizing the storage bin 2.
[0039] like Figure 2 As shown, in some embodiments, the suction pipe 42 is disposed on the side wall of the corresponding discharge pipe 31; the upper end of each suction pipe 42 is connected to a guide pipe 43, and the guide pipe 43 is connected to the middle of the dust collection chamber 41.
[0040] In this embodiment, the suction pipe 42 moves along with the discharge pipe 31, that is, the suction pipe 42 is fixedly installed on the side wall of the discharge pipe 31, and the upper end of the suction pipe 42 is connected through the flexible guide pipe 43.
[0041] like Figure 3 As shown, in some embodiments, the side wall of the dust collection chamber 41 is provided with a plurality of blow pipes 411; each blow pipe 411 is connected to the air manifold 412, and each blow pipe 411 is provided with a pulse solenoid valve 413.
[0042] In this embodiment, a filter bag is provided in the dust collection chamber 41. The filter bag is used to filter the absorbed dust and prevent the dust from being discharged from the negative pressure generator 5. After the filter bag has been used for a period of time, the resistance of the negative pressure generator 5 will increase due to the excessive dust adsorbed on the filter bag. When the resistance reaches a certain value, the pulse solenoid valve 413 opens and the air bag 412 blows air into the filter bag, causing the dust adhering to the outer wall of the filter bag to fall off.
[0043] like Figure 2 As shown, in some embodiments, the discharge mechanism 3 further includes: a plurality of transverse adjustment platforms 32; wherein the discharge pipe 31 is disposed on the corresponding transverse adjustment platform 32; the transverse adjustment platform 32 is adapted to adjust the spacing of the discharge pipe 31.
[0044] Specifically, the lower surface of the transverse adjustment table 32 is provided with a slider, a motor and a gear, and the moving platform 6 is provided with a guide rail and a rack; wherein, the gear and rack mesh, that is, the transverse adjustment table 32 is driven by the motor to rotate the gear, thereby causing the transverse adjustment table 32 to slide on the guide rail.
[0045] In this embodiment, in order to adapt to different needs, the number and spacing of the baffles in the furnace cavity 71 will be adjusted. Therefore, a transverse adjustment platform 32 is set for each discharge pipe 31 to drive the discharge pipe 31 to move horizontally, so that the discharge pipe 31 can be aligned with the feeding position.
[0046] like Figure 4 As shown, at least one embodiment also provides a mobile feeding trolley for a graphitization furnace, including: a mobile platform 6 on which a dust collection device for a graphitization furnace is provided; wherein a pair of roller sets 61 are provided on the lower surface of the mobile platform 6; a pair of drive motors 62 are provided on the mobile platform 6, and a spur gear 63 is provided at the end of the drive motors 62.
[0047] For the specific structure and implementation process of the dust collection device for the graphitization furnace, please refer to the relevant discussion in the above embodiments, which will not be repeated here.
[0048] In this embodiment, the dust collection device for the graphitization furnace is set on the mobile platform 6, so that the mobile platform 6 can carry the annular tubular chain conveyor 1, the storage silo 2, the discharge mechanism 3, the bag filter 4 and the negative pressure generator 5 to move to the required location for feeding and dust removal.
[0049] like Figure 4 As shown, at least one embodiment also provides a graphitization furnace system, including: a graphitization furnace body 7, on which a plurality of furnace cavities 71 are disposed; and a plurality of graphitization furnace mobile feeding trolleys, respectively disposed above the corresponding furnace cavities 71.
[0050] For the specific structure and implementation process of the mobile feeding trolley for the graphitization furnace, please refer to the relevant discussion in the above embodiments, which will not be repeated here.
[0051] In some embodiments, the upper surface of the graphitization furnace body 7 is provided with a track 72 adapted to the roller assembly 61; the upper surface of the graphitization furnace body 7 is provided with a spur gear 73 adapted to the spur gear 63.
[0052] In this embodiment, the spur gear 63 meshes with the spur rack 73 so that when the spur gear 63 rotates, the moving platform 6 moves along the arrangement direction of the track 72.
[0053] In summary, the dust collection device, mobile feeding trolley, and graphitization furnace system of this graphitization furnace adopt a bag filter 4, which extends the suction pipe 42 of the bag filter 4 to the outlet pipe 31. This allows the negative pressure to absorb the dust generated by the material discharged from the outlet pipe 31 into the dust collection bin 41, and the dust in the dust collection bin 41 is directly sent to the annular tubular chain conveyor 1. This not only avoids material loss caused by dust, but also directly sends the collected dust into the annular tubular chain conveyor 1.
[0054] In this document, when it is said that the first component is located on the second component, this can mean that the first component can be directly formed on the second component, or that the third component can be inserted between the first component and the second component.
[0055] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.
[0056] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as “at least one of…” modify the entire list of elements when following a list of elements, rather than individual elements in the list. For example, the expression “at least one of a, b, and c” should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.
[0057] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0058] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
