Description

Technical Field

[0001] The utility model relates to the technical field of graphite feeding, in particular to a negative pressure feeding device for graphite processing. Background Art

[0002] Graphite is an allotrope of carbon, a gray-black, opaque solid with stable chemical properties, corrosion resistance, and low reactivity with acids and alkalis. Natural graphite comes from graphite deposits, but it can also be made from petroleum coke, asphalt coke, and other raw materials through a series of processing steps to produce artificial graphite. Graphite burns in oxygen to produce carbon dioxide, which can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate. It is used as an anti-wear agent and lubricant. High-purity graphite is used as a neutron moderator in nuclear reactors. It is also used in the manufacture of crucibles, electrodes, brushes, dry cell batteries, graphite fibers, heat exchangers, coolers, arc furnaces, arc lamps, and pencil refills.

[0003] Patent specification CN212238558U discloses a device for collecting dust from graphite materials used in the negative electrode of lithium batteries. The device comprises a dust box, a movable assembly disposed at the bottom of the dust box, a motorized lifting column fixedly mounted to the bottom of the movable assembly, a support plate fixedly mounted at the bottom end of the motorized lifting column, and a positioning slot formed at the bottom of the support plate. The device can be moved to a processing location for the negative electrode material, a dust hood and a dust collection tube rotated above the processing equipment via a rotating shaft, and a dust collection fan activated to create a negative pressure state between the interior and exterior of the dust box. The generated suction draws floating dust and pollutants during processing into the dust box, where they are then collected and adsorbed by a dust sticking plate and an activated carbon adsorption membrane, preventing the random spread of dust particles and pollutants from affecting the processing environment and harming the health of processing personnel.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: the above device is not convenient for discharging the residual graphite inside the device during use, and it is difficult to carry out complete collection work. At the same time, during use, a large amount of graphite will enter the device, causing toner to fly, which directly affects the on-site working environment. Therefore, further improvement is needed.

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figures 1 to 4As shown, this embodiment proposes a negative pressure feeding device for graphite processing, including a fixed seat 1, a fixed plate 2 is fixedly connected to the top of the fixed seat 1, a sliding shell 3 is slidably connected to the outer side of the fixed plate 2, a negative pressure machine 5 is fixedly connected to the outer side of the sliding shell 3, a tube body 4 is fixedly connected to the inside of the negative pressure machine 5, a connecting pipe 6 is connected to the bottom of the sliding shell 3 through a bearing, a rotating plate 7 is fixedly connected to the outside of the connecting pipe 6, a connecting plate 8 is fixedly connected to the inside of the connecting pipe 6, and a scraper 9 is fixedly connected to the top side of the connecting plate 8.

[0027] In this embodiment, the scraper 9 is fitted and in contact with the interior of the sliding shell 3, and a guide rod 10 is fixedly connected to one side of the bottom of the connecting plate 8, which can facilitate the connecting plate 8 to drive the guide rod 10 to rotate.

[0028] In this embodiment, the guide rod 10 is L-shaped, a cylinder 11 is provided outside the connecting tube 6 , and a rotating plate 12 is connected to the bottom of the inner cavity of the cylinder 11 through a bearing, so that the cylinder 11 can collect toner.

[0029] In this embodiment, a second scraper 13 is fixedly connected to one side of the outer portion of the rotating plate 12 . One side of the second scraper 13 contacts the outer surface of the guide rod 10 , which facilitates the rotation of the second scraper 13 .

[0030] When using, when it is necessary to carry out negative pressure feeding of graphite, first the staff needs to insert the tube body 4 into the external graphite, and then turn on the negative pressure machine 5. The negative pressure machine 5 will work at this time and suck the external graphite into the interior of the sliding shell 3 through the tube body 4. When the graphite enters the interior of the sliding shell 3, it will fall into the interior of the cylinder 11 through the connecting tube 6 for collection. In order to ensure that the toner does not overflow and affect the working environment during the graphite collection process, the baffle 14 will block the toner. When the graphite feeding is completed, the staff needs to hold the rotating plate 7 and rotate it. The rotating plate 7 will synchronously drive the connecting tube 6 and the connecting plate 8 to rotate during the rotation. The connecting plate 8 will synchronously drive the scraper 9 to rotate during the rotation. The scraper 9 will synchronously clean the toner adhered to the inner wall of the sliding shell 3 during the rotation, so that the toner falls completely into the interior of the cylinder 11 through the connecting tube 6.

[0031] In the process of driving the connecting plate 8 to rotate, the connecting tube 6 will also synchronously drive the guide rod 10 to rotate. In the process of rotation, the guide rod 10 will contact the scraper 2 13 and drive the scraper 2 13 to rotate. In the process of rotation, the scraper 2 13 will synchronously scrape off the toner on the bottom of the baffle 14 and the inner wall of the cylinder 11, thereby achieving a complete collection effect.

[0032] Example 2

[0033] like Figure 2 and Figure 3As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a baffle 14 is provided on the top of the cylinder 11, and the outer surface of the scraper 13 is in contact with the bottom of the baffle 14 and the inside of the cylinder 11 respectively, and a plurality of perspective windows are embedded in the baffle 14, which can facilitate the baffle 14 to block the toner.

[0034] In this embodiment, the inside of the baffle 14 is connected to the connecting pipe 6 via a bearing, and a plurality of positioning rods 15 are fixedly connected to the outside of the baffle 14 , which can facilitate the connection between the baffle 14 and the positioning rods 15 .

[0035] In this embodiment, the plurality of positioning rods 15 are all configured to be L-shaped, and a plurality of positioning shells 16 are fixedly connected to the outside of the cylinder 11 , which can facilitate the fixed connection work of the positioning shells 16 .

[0036] In this embodiment, the plurality of positioning rods 15 extend into the interior of the plurality of positioning shells 16 respectively, and the plurality of positioning rods 15 are in contact with the interior of the plurality of positioning shells 16 respectively, which can facilitate the connection and limiting work of the positioning rods 15 .

[0037] During use, if it is necessary to separate the cylinder 11, the staff will move the sliding shell 3 upwards. The sliding shell 3 will move relative to the fixed plate 2 during the movement, that is, the sliding shell 3 slides on one side of the fixed plate 2. At the same time, the sliding shell 3 will synchronously drive the connecting tube 6 and the baffle 14 to move during the movement. At this time, the staff needs to lift the baffle 14 upwards. The baffle 14 will synchronously drive the positioning rod 15 to leave the inside of the positioning shell 16 during the lifting process, thereby achieving the separation effect of the cylinder 11 and facilitating subsequent work on the toner.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
