Description

Technical Field

[0001] The utility model relates to the technical field of graphite screening, in particular to a classification device for expandable graphite. Background Technique

[0002] The graphite crystal has a hexagonal network planar layered structure composed of carbon elements. The carbon atoms on the layer plane are combined by strong covalent bonds, while the layers are combined by van der Waals forces, the combination is very weak, and the distance between layers is relatively large. Therefore, under appropriate conditions, various chemical substances such as acids, alkali metals, and salts can be inserted between the graphite layers and combined with carbon atoms to form a new chemical phase - graphite intercalation compound. When this intercalation compound is heated to an appropriate temperature, it can decompose instantaneously and rapidly, generating a large amount of gas, causing the graphite to expand axially into a worm-like new substance, that is, expandable graphite. This unexpanded graphite intercalation compound is expandable graphite.

[0003] In the Chinese utility model patent with the publication number of CN220716644U, a classification and screening machine for graphite powder is disclosed. By setting telescopic rods, the screen can swing, facilitating subsequent cleaning; the screen can swing, and the angle of the screen can be adjusted according to actual needs, improving the screening accuracy and efficiency.

At the same time, the process of taking out the graphite is very troublesome. Moreover, during continuous multi-batch screening, taking out the graphite multiple times will increase the time cost and affect the screening efficiency of the device. Content of the Utility Model

The bottom of the limiting rod 13 is fixedly connected to the top of the bottom plate 1. A spring 14 sleeved on the outer side of the limiting rod 13 is connected between the bottom of the support plate 4 and the top of the bottom plate 1. One end of the rotating rod 2 is fixedly connected to a gear 5, and the adjacent gears 5 mesh with each other. The other end of the middle rotating rod 2 is fixedly connected to a motor 6, and the motor 6 is installed on the top of the bottom plate 1.

[0027] The classification screening assembly is used to classify and screen the expandable graphite. The classification screening assembly includes two fixed plates 7 and a screening box 8 fixedly connected to the top of the support plate 4. Two bearings are installed on the surface of the fixed plate 7. A rotating rod 9 is installed inside the bearings. One end of the rotating rod 9 is fixedly connected to a handwheel to facilitate the rotation of the rotating rod 9. The right end of the left rotating rod 9 is connected to a screening box A10. Two screening boxes B11 are installed inside the screening box 8. Square rods are fixedly connected to the left side of the screening box A10 and the right side of the screening box B11. A square groove adapted to the square rod is opened at one end of the rotating rod 9 to facilitate the rotating rod 9 to drive the screening box A10 or the screening box B11 to rotate. Both the screening box A10 and the screening box B11 are composed of a connecting frame, a filter screen and four L-shaped rods. Card slots are opened on both sides of the top of the connecting frame. The L-shaped rods abut against the inside of the card slots. A bolt is connected between the bottom of the L-shaped rod and the top of the filter screen. Sockets are opened on the front and back of the connecting frame and the surface of the L-shaped rod. Plug rods are installed in the sockets to facilitate the replacement and repair of the filter screen on the screening box A10 or the screening box B11. The screening box A10 and the screening box B11 are connected by a connecting rod. The two ends of the connecting rod are respectively rotatably connected to the left side of the screening box A10 and the right side of the screening box B11. Through grooves for the movement of the screening box A10 and the screening box B11 are opened on the surface of the screening box 8 to facilitate the movement of the screening box A10 and the screening box B11.

[0028] In the embodiment of the present application, the implementation principle of a grading device for expandable graphite is as follows: When screening the expandable graphite in the device, first start the motor 6, and then introduce the expandable graphite into the screening box 8 through the feeding trough. The motor 6 drives the cam 3 to rotate through the rotating rod 2, causing the cam 3 to continuously strike the support plate 4. Under the action of the limiting rod 13 and the spring 14, the support plate 4 continuously vibrates, thereby driving the expandable graphite in the screening box 8 to vibrate, causing the expandable graphite to be lifted, facilitating the grading and screening of the expandable graphite, and improving the screening effect of the device.

[0029] After the expandable graphite is poured into the screening box 8 through the feeding trough, under the action of the vibration assembly, the expandable graphite passes through the two screening boxes A10 or the two screening boxes B11, enabling the expandable graphite to be screened out according to different specifications. At the same time, the two screening boxes A10 or the two screening boxes B11 are subjected to the abutting action of the through slots, so that the two screening boxes A10 or the two screening boxes B11 are arranged on the screening box 8. After the screening is completed, switch the screening boxes A10 and B11, and then replace the collection box at the bottom, and then the screening of the next batch of expandable graphite can be carried out. At the same time, after the square rod on the screening box A10 or the screening box B11 is inserted into the rotating rod 9, rotate the rotating rod 9, so that expandable graphite of different grades respectively falls into the two receiving boxes 12, completing the grading, screening and collection, making the device have better continuity during continuous multi-batch screening, reducing the time cost, and improving the working efficiency of the device.

[0030] When the filter screen on the screening box A10 or the screening box B11 is damaged, take out the inserting rod, and then rotate the bolt to separate the filter screen and the L-shaped rod from the connecting frame on the screening box A10 or the screening box B11. Then install the new filter screen on the L-shaped rod through the bolt. Finally, clamp the L-shaped rod in the card slot on the connecting frame, and re-insert the inserting rod into the socket to complete the limit fixation of the L-shaped rod, thereby realizing the replacement of the filter screen, which is convenient and fast.
