Description

Technical Field

[0001] This invention belongs to the field of kiln facilities technology, and specifically relates to a device for uniformly distributing material in a sagger. Background Technology

[0002] The aforementioned feeding device can also be called a loading device or a filling device. As is known in the art, a sagger conveyor mechanism, which serves as a production line, is usually installed between the furnace inlet and furnace outlet of a tunnel kiln used for calcining various electronic materials, lithium battery anode materials, etc. On the path of the sagger conveyor frame of this sagger conveyor mechanism, i.e., on the channel, according to process requirements, there are, but are not limited to, the following examples, such as a sagger calcining material crushing mechanism, a sagger unloading mechanism, a sagger cleaning mechanism, a sagger crushing and un-crushing inspection mechanism, and a sagger loading mechanism. The saggers containing calcined materials are transported from the furnace to the sagger calcination material crushing mechanism by the sagger conveyor. The calcined material is crushed (because many materials will form stubborn lumps after calcination). After crushing at the sagger calcination material crushing station, the sagger conveyor sends it to the sagger unloading mechanism to unload the material from the sagger (or the material can be sucked out directly by the suction pipe at the crushing station). Then, the sagger conveyor transports the unloaded saggers to the sagger cleaning station, where the aforementioned sagger cleaning mechanism cleans them. After that, the saggers are inspected at the sagger inspection station to remove broken and / or cracked saggers. The sagger conveyor then transports the saggers to the loading station, where the sagger loading mechanism loads them. Finally, the sagger conveyor sends the saggers into the furnace from the furnace inlet, thus forming a cyclical, highly efficient production line process.

[0003] As is known in the field, some materials, such as graphene (often called "graphite material") in the category of lithium-ion battery anode materials, are modified and removed by high-temperature calcination to change and remove the microstructure and impurities in graphite, thereby improving the conductivity, oxidation resistance, density, and mechanical strength of the raw material, etc. Currently, graphite powder is loaded into the sagger by a single-point center feeding method (i.e., feeding the material into the center of the sagger). Specifically, the material is fed into the sagger in a quantitative manner (the material in each sagger is the same) through a feeding port connected to the material cylinder. This feeding method often results in the material in the sagger forming a pagoda shape. The so-called pagoda shape means that the material in the middle or center of the sagger cavity is significantly higher than the upper plane of the sagger, while the surrounding area of ​​the sagger cavity is severely lacking in material. Therefore, the usual practice is to assign a worker to the workstation where the aforementioned sagger loading mechanism is located, and the worker scrapes the material with a square pyramid effect evenly using appropriate tools. However, the aforementioned handling method has at least the following technical problems: First, it wastes valuable labor resources because it requires additional workers to level the material in the sagger. Second, during the manual leveling process, even slight carelessness can cause relatively expensive material to be scraped out of the sagger, resulting in waste. Third, some materials, such as the aforementioned graphene material, are relatively loose due to their high air content. Therefore, the dust generated during manual leveling not only severely damages the working environment but also poses a significant health risk to workers, such as those who work in this field for extended periods and are at risk of developing pneumoconiosis. Based on the above, exploring how to avoid the tower effect (i.e., a high filling point with significantly lower surrounding areas) of material fed into the sagger through the feeding pipe is of positive significance. The technical solution described below arose in this context. Summary of the Invention

[0004] The objective of this invention is to provide a uniform material distribution device for a sagger that can make the material fed into the sagger by the feeding pipe present a uniform distribution at multiple points and make the material surface more consistent, thereby eliminating the need for workers to level the material surface, preventing the material from overflowing out of the sagger, and ensuring both the working environment and the health of the on-site operators.

[0029] The aforementioned crucible feed tube fixing plate opening and closing drive motor 21, crucible left feed tube sliding plate front slider position signal acquisition device 1211, and crucible right feed tube sliding plate front slider position signal acquisition device 1221 are electrically connected to the electrical controller in use.

[0030] When the crucible arrival signal collector, located on the frame of the crucible conveyor mechanism (which serves as the production line), detects a signal of a crucible (empty crucible) being conveyed by the crucible conveyor rollers of the frame (the crucible has reached the station where the crucible loading device of this invention is located), the crucible arrival signal collector feeds the signal back to the electrical controller. The electrical controller then sends a working command to the crucible feeding tube fixing plate opening and closing drive motor 21, which then drives the crucible feeding tube fixing plate opening and closing. Motor 21 operates clockwise, driving the crucible feed tube fixing plate opening and closing drive reduction gearbox 27. The final stage power output shaft 272 of the crucible feed tube fixing plate opening and closing drive reduction gearbox drives the crucible feed tube fixing plate opening and closing drive drive wheel 22. The crucible feed tube fixing plate opening and closing drive drive wheel 22, via the crucible feed tube fixing plate opening and closing screw drive wheel transmission belt 24, drives the crucible feed tube fixing plate opening and closing screw drive wheel 23. The crucible feed tube fixing plate opening and closing screw drive wheel 23 then drives the crucible feed tube... The rotation of the feed pipe fixing plate opening and closing screw 25 causes the left thread 251 of the opening and closing screw at the left end of the feed pipe fixing plate 25 to drive the left nut block 26b of the opening and closing screw, while the right thread 252 of the opening and closing screw at the right end of the feed pipe fixing plate 25 drives the right nut block 26c of the opening and closing screw. Since the helical directions of the left and right threads 251 and 252 of the opening and closing screw are opposite, during the aforementioned process, the rotation of the feed pipe fixing plate opening and closing screw 25... The movement causes the left and right nut blocks 26b and 26c of the opening and closing screw to move towards each other. This movement, in turn, causes the left and right feed tube sliding plates 31 and 32 of the crucible to move towards each other, until the signal from the aforementioned right feed tube sliding plate front slider position acquisition device 1221 is detected, indicating that the left and right feed tube sliding plates 31 and 32 have moved towards each other and are now closed. Simultaneously, the right feed tube sliding plate front slider position acquisition device 1221 feeds back the collected signal to the electrical controller, which then sends a stop command to the crucible feed tube fixing plate opening and closing drive motor 21. In this state, the closing of the left and right feed tube sliding plates 31 and 32 causes the pair of left feed tubes 33 and the pair of right feed tubes 34 to also move towards each other and are in a closed position. Figure 2 , Figure 3 The shown approaching state is essentially a state of feeding material into the saggers located simultaneously below a pair of left feed pipes 33 and a pair of right feed pipes 34.

The sliding plates 31 and 32 of the left and right feed pipes are pushed apart to form a closed contact. Figure 1The state shown is determined by the reverse operation of the sagger feed tube fixing plate opening and closing drive motor 21 until the left feed tube sliding plate front slider 311 of the sagger moves to the left to the extent that the signal is acquired by the sagger left feed tube sliding plate front slider position signal acquisition device 1211. Figure 1 In the indicated state, the left and right feed tubes 33 and 34 of the crucible move away from the area corresponding to the crucible cavity due to their displacement in opposite directions. At this time, the position signal acquisition device 1211 of the slider in front of the left feed tube of the crucible collects the signal and feeds it back to the electrical controller. The electrical controller then sends a stop signal to the opening and closing drive motor 21 of the crucible feed tube fixing plate. In this embodiment, the aforementioned position signal acquisition devices 1211 and 1221 of the slider in front of the left and right feed tubes of the crucible use microswitches, but limit switches, proximity switches, reed switches, or Hall effect sensors can also be used.

[0037] The applicant describes a system consisting of a pair of left feed tubes 33 and a pair of right feed tubes 34 for feeding the saggars, corresponding to the feed tubes 34 for feeding the saggars. Figures 3 to 5 The feeding process in the sagger (not shown in the figure) below the sagger compaction sleeve 102, as shown, firstly involves the operation of the aforementioned sagger feeding tube fixing plate opening and closing drive mechanism 2, which causes the aforementioned left and right feeding tube sliding plates 31 and 32 of the sagger to be in a state of... Figure 2The closed state is shown. Since the operation process of the crucible feed tube fixing plate opening and closing drive mechanism 2 has been described above, it will not be repeated. When the electrical controller receives the signal from the slider position signal acquisition device 1221 of the right feed tube sliding plate of the crucible, it sends a stop signal to the aforementioned crucible feed tube fixing plate opening and closing drive motor 21 and a working command to the gas generating device, causing a set of feed opening and closing valve plate actuation mechanisms 5 to work simultaneously and synchronously. Specifically, the feed opening and closing valve plate actuation cylinder 52 works, causing the feed opening and closing valve plate actuation cylinder column 522 to move upwards into the cylinder body. The feed opening and closing valve plate actuation cylinder column 522 drives the cylinder column length adjusting rod hinge joint 54 through the cylinder column length adjusting rod 53. Since the cylinder column length adjusting rod hinge joint 54 is hinged to a pair of cylinder column length adjusting rod hinge joint pins 59 on a pair of cylinder column length adjusting rod hinge joint pin hinge ears 55, and the pair of cylinder column length... The hinge lug 55 of the length adjustment rod hinge joint is fixed to the edge or edge of the feeding valve plate 4. Therefore, the cylinder length adjustment rod hinge joint 54, through the cylinder length adjustment rod hinge joint pin 59, drives a pair of cylinder length adjustment rod hinge joint pin hinge lugs 55. These lugs 55 then lift the aforementioned edge of the feeding valve plate 4. Since the central part of the feeding valve plate 4 corresponds to the bottom of the aforementioned lower degassing screw chamber 621 and is in a free state, as the edge of the feeding valve plate 4 is lifted by the cylinder length adjustment rod hinge joint pin hinge lug 55, the previously blocked state of the bottom of the aforementioned lower degassing screw chamber 621 changes to a downward opening state. Figure 5 The state shown, more specifically, is such that a set of feed on / off valve plates 4 are in the previous state as described above. Figure 7 The lower part of the blanking cavity 62413 shown in the figure is changed from a closed state to an open state and is in the form of... Figure 5 The diagram shows a near-vertical open state. Under the rotation of the aforementioned agitator screw 20, its agitator blades 201 sequentially feed material from the material cylinder cavity 72 of the material cylinder 7 into the lower sagger via the upper degassing screw filter sleeve cavity 631, the lower degassing screw filter sleeve cavity 641, the material discharge hollow cavity 62413, the feeding valve plate cavity 1021, and the left and right feeding pipes 33 and 34 of each pair of saggers. During this process, the degassing interfaces 616 and 625 of the upper and lower degassing screw cylinder cavities are in a state of negative pressure extraction of air from the material in the upper and lower degassing screw filter sleeve cavities 631 and 641. The air in the material cylinder 7 is introduced by a degassing actuator (not shown in the diagram).

[0038] After feeding the crucible is completed, the aforementioned feeding opening and closing valve plate actuating cylinder 52 reverses its operation, causing the aforementioned feeding opening and closing valve plate 4 to return to its original position according to the reverse process. Figure 3 and Figure 4The lower part of the degassing screw cylinder cavity 621 shown is in a closed state relative to the feeding hollow cavity 62413. This state means that the feeding valve plate 4 is in a closed state in conjunction with the feeding valve plate cavity 1021. At the same time, under the reverse operation of the crucible feeding pipe fixing plate opening and closing drive motor 21, the aforementioned crucible left and right feeding pipe sliding plates 31 and 32 are pushed apart and form a closed state. Figure 1 The state shown.

[0039] The control of the material quantity in the aforementioned feeding state, i.e., the control of the fullness of the sagger, can be achieved in any of the following forms, not limited to: Firstly, it is achieved through the pressure sensed by a pressure sensor (i.e., a pressure sensor) on the sagger lifting mechanism (also called a "sagger lifting mechanism") on the sagger conveyor frame, which is part of the aforementioned production line. Specifically, a pressure sensor is installed at the bottom of the sagger lifting mechanism corresponding to the station where the sagger uniform distribution device of this invention is located. When the pressure sensor senses the required material quantity (pressure value) in the sagger, it feeds a signal back to the electrical controller. The electrical controller then sends commands to the aforementioned feeding opening / closing valve plate actuation cylinder 52 and the sagger feeding pipe fixing plate opening / closing drive motor 21, thereby achieving the aforementioned stopping of the feeding process, i.e., realizing a set of feeding... The four scenarios are as follows: 1) Closing the material opening / closing valve plate 4 on the material feeding cavity 62413; 2) When the material level in the sagger reaches full capacity, the material level sensor on the outer wall of the pair of left feeding pipes 33 and / or the pair of right feeding pipes 34 can detect the material level and feed the signal back to the electrical controller, the rest being the same as described in the first scenario; 3) The weighing sensor 834 of the aforementioned weighing device 83 can detect the decrease in weight of the material cylinder 7 and feed the signal back to the electrical controller, because the weight reduction of the material cylinder 7 each time is exactly the amount fed into the sagger each time, the rest being the same as described in the first scenario; 4) A sagger material level detection sensor is installed at a reasonable position on the sagger conveyor frame of the sagger conveyor mechanism to detect the material level in the sagger, the rest being the same as described in the first scenario. In this embodiment, the first of the above four scenarios is selected.

[0040] After the feeding of the saggers is completed, the sagger lifting mechanism (not shown in the figure), i.e., the sagger top lifting mechanism, pushes the saggers upward. A set of feeding opening and closing valve plates 4, which are in the closed state and correspond to the feeding opening and closing valve plate cavity 1021, cooperate with the aforementioned sagger material compaction sleeve 102 to compact the material inside the saggers. After the compaction time set by the electrical controller, the aforementioned sagger lifting mechanism descends and places the saggers onto the sagger conveying rollers of the sagger conveying mechanism frame, and conveys them to the next station, such as entering the furnace from the furnace inlet. The next sagger pair waiting to be loaded is led from the previous station to the station where the sagger uniform material distribution device of the present invention is located.

[0041] In summary, since the sagger feeding mechanism assembly 3 of the present invention uses a pair of left sagger feeding pipes 33 and a pair of right sagger feeding pipes 34, it innovatively embodies the uniform distribution of material to four points in the sagger cavity, abandons the single-point center feeding method that has been followed in the industry for a long time, eliminates the root cause of the four-sided pyramid shape, and fully realizes the technical effects recorded by the applicant in the above technical effects column.
