DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0029] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0030] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0031] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0032] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0033] The lithium battery graphitization furnace is mainly used for the graphitization of crucibles. The furnace body of the lithium battery graphitization furnace is mostly a rectangular furnace with an open top, and the furnace body is relatively large. During operation, the multiple crucibles that need to be graphitized are first placed in the middle part of the furnace body, and then the resistor material is placed around the crucible, that is, in the center of the furnace body, and the insulation material is placed between the inner wall of the furnace body and the crucible. The resistor material and the insulation material are both powder materials that are easy to raise dust. The current operation method is to first use a crane to lift the ton bag filled with powder (resistance material and / or insulation material), and the on-site staff will operate to transport the ton bag to the corresponding position in the furnace body. Specifically, it is necessary to set up a ladder in the furnace body, and the staff climb into the furnace body along the ladder from the edge of the furnace body, and then another group of staff will lift the ton bag filled with powder onto the crane, and then the staff in the furnace body will control the crane to transport the ton bag to the designated location, and then the staff in the furnace body will open the ton bag to lay the powder in the furnace body. The whole process is laborious and dusty. The material collection process is even more tiring. Specifically, the staff enters the furnace body, stands on the material powder, collects the powder little by little into the transfer container and transports it out of the furnace body. The process is also time-consuming and laborious, and serious dust is generated.

After receiving the finished materials, the feeding device 3 moves to the graphitization furnace 1 for feeding, and then the feeding device 3 leaves the graphitization furnace 1. The graphitization furnace 1 graphitizes the workpiece in the furnace. After the graphitization is completed and fully cooled, the suction device 4 moves to the graphitization furnace 1.

After the suction device 4 is fully absorbed, it moves to the discharge transfer bin 51 and puts the waste materials into the discharge transfer bin 51, and the discharge fan 52 is turned on to suck the waste materials in the discharge transfer bin 51 into the discharge bin 53. The discharge fan 52 is closed, and the discharge port of the discharge bin 53 is opened.
