Description

Technical Field

[0001] The present invention relates to the field of graphite processing, and more specifically to an isostatic graphite crushing and processing device. Background Art

[0002] Isostatic graphite processing refers to a graphite forming method. After isostatic pressing, graphite materials with anisotropic microstructures can exhibit isotropic macroscopic properties. Before isostatic pressing of graphite, high-temperature graphitization treatment is first performed on the graphite. During the high-temperature graphitization treatment, the graphite needs to be in a pulverized state.

[0003] During the process of graphite crushing and grinding, one method is to directly use a crusher or grinding device to crush the graphite and directly output the crushed graphite. Another method is to use air flow sorting after crushing the graphite. The particle size of the graphite powder produced by this method is often much finer and often exhibits better performance during isostatic graphite processing. However, during production, air often brings larger particles into the collection device. These particles need to be classified and collected in the sorting device, and then these particles need to be put back into the grinding device. The existing method for processing these particles in the machine is to rotate a cylindrical sorting workpiece with a grid on its side to block these particles. However, due to the diameter problem of the discharge port, in order to ensure the smooth flow of air, the side of the workpiece cannot be processed too thick. Therefore, most larger particles still have a high probability of passing through the above workpiece. Summary of the Invention

[0024] Advantages of the present invention:

[0025] 1. By winding the filter screen roller and the filter screen tightening roller, the length of the filter screen is greatly increased in the present invention. Only by driving the rotation of the filter screen roller with a driving device such as a motor, the rapid conversion of the filter screen in the filtering state can be realized, thereby greatly increasing the service life of the filter screen.

[0027] 3. In the present invention, when there are many particles deposited on the filter screen, which causes the filter screen to be blocked, the gas will be compressed inside the shell, thereby pushing the air inlet disk. When the air inlet disk contacts the air blocking pipe, it will push the air blocking pipe. When the ventilation groove enters the middle position of the air inlet pipe, the compressed air accumulated in the compressed air cavity will enter the discharge pipe and the inside of the filter screen device, and the impurities accumulated on the filter screen will be effectively cleaned under the impact of the compressed air.

[0028] 4. When compressed air enters the discharge pipe, due to the violent expansion of the gas, it will impact the recoil plate. A block is installed on the discharge pipe corresponding to the recoil plate. When the recoil plate contacts the block, the recoil plate will unfold, and when the recoil plate is fully unfolded, the block will resist the upper end of the recoil plate. In this way, the recoil plates in the two recoil gas mechanisms will block most of the space in the discharge pipe, so that the remaining compressed air will blow the filter with greater force, thereby better removing impurities on the filter.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] To solve the technical problems proposed in the present invention;

[0044] As Figure 1 、 Figure 2 and Figure 3 shown, the present invention provides an isostatic graphite crushing and processing device, which is characterized by including:

[0045] Base 1, the upper end of the base 1 is fixedly installed with an outer shell 2, and the lower end of the base 1 is provided with an air inlet 11;

[0046] Ring roller 3, the ring roller 3 is rotatably connected to the upper end of the base 1, and the lower end of the ring roller 3 is fixedly installed with an annular first baffle 31;

[0047] The grinding plate 4 is fixedly installed on the housing 2. A plurality of grinding cavities 41 are successively formed in the grinding plate 4 from top to bottom. A plurality of grinding wheels 32 are circumferentially and evenly rotatably connected to the annular roller 3 corresponding to each grinding cavity 41. The distance between the grinding wheel 32 and the cavity wall of the grinding cavity 41 is very small but they do not contact each other.

[0048] The air duct plate 5 is in the shape of a hollow cylinder and is fixedly installed at the upper end of the grinding plate 4;

[0049] The first separation device 6 is rotatably connected to the middle position at the upper end of the inner cavity of the housing 2;

[0050] The second separation device 7 is arranged at the middle position at the upper end of the inner cavity of the housing 2;

[0051] The feed pipe 21 passes through the housing 2 and the air duct plate 5 and extends into the upper end of the grinding plate 4. The feed pipe 21 is fixedly installed on the housing 2;

[0052] The upper end of the housing 2 is fixedly connected with a discharge pipe 8.

[0053] It should be noted that during the process of crushing graphite, first, the graphite to be processed is placed at the position of the feed pipe 21. At this time, the annular roller 3 is rotated by the motor. The graphite material will rotate along with the upper end surface of the annular roller 3 and slide into the position between the annular roller 3 and the grinding plate 4 under the action of centrifugal force. When the graphite enters the position of the grinding cavity 41, under the extrusion of the grinding wheel 32, the graphite will be crushed and fall into the next grinding cavity 41 and be extruded by the grinding wheel 32 again. After multi-stage extrusion, the graphite will be crushed and fall on the first baffle 31 and enter the position between the grinding plate 4 and the housing 2 under the action of centrifugal force. At this time, the high-speed air flow blown out from the air inlet 11 will drive the ground graphite powder into the position between the air duct plate 5 and the housing 2 and enter the feed pipe 21 from the upper end of the air duct plate 5. During this process, the first separation device 6 will rotate to knock the larger particles onto the upper end of the annular roller 3 and grind them again. The sufficiently refined particles will flow through the first separation device 6 and the second separation device 7 along with the air flow and finally enter the feed pipe 21. If there are larger particles passing through the first separation device 6, the second separation device 7 will filter the particles to further remove the non-conforming particles, and finally discharge the screened graphite particles through the discharge pipe 8.

[0054] Such as Figures 4 to 7As shown, the second separation device 7 includes a separation platen 71. The separation platen 71 is fixedly installed at the upper end of the housing 2. The separation platen 71 is designed as a regular polygon and there are two separation platens 71, one above the other. Connecting plates 72 are fixedly connected to the separation platens 71 at diagonal positions. The connecting plates 72 fixedly connect the two separation platens 71. A filter device 73 is installed between adjacent connecting plates 72. The discharge pipe 8 is connected to the upper separation platen 71 and communicates with the position between the two separation platens 71.

[0055] It should be noted that during use, when the gas passes through the second separation device 7, it mainly enters the second separation device 7 through the filter device 73. During this process, designing the separation platen 71 in a polygonal shape can accommodate multiple filter devices 73, which can improve the air intake efficiency, and thus further remove graphite particles.

[0056] As Figures 4 to 7 shown, the filter device 73 includes a filter reel 731, a filter tightening wheel 732, a filter net 733, and a tightening spring 734. The filter reel 731 is rotatably connected to the upper separation platen 71, and the filter tightening wheel 732 is rotatably connected to the lower separation platen 71. The upper and lower ends of the filter net 733 are respectively wound by the filter reel 731 and the filter tightening wheel 732. Tightening springs 734 are fixedly installed between both ends of the filter tightening wheel 732 and the lower separation platen 71.

[0057] It should be noted that during use, particles will gradually accumulate and deposit on the surface of the filter net. By winding the filter reel 731 and the filter tightening wheel 732, the length of the filter net 733 is greatly increased. Only by driving the rotation of the filter reel 731 with a driving device such as a motor can the rapid conversion of the filter net in the filtering state be achieved. Moreover, the upper and lower separation platens 71 will press against the outside of the filter net 733, so that the particles on the filter net 733 will be removed during the relative sliding process between the filter net 733 and the separation platens 71.

[0058] The filter net 733 can be divided into several different section segments, and the diameters of the particles that can pass through each section segment are different.

[0059] During use, by the above technical means, by putting different section segments of the filter net 733 in contact with the outside air, graphite powder in different particle size states can be screened according to actual screening needs.

[0060] As Figure 2 、 Figure 5 and Figure 10As shown in the figure, an air inlet platform 9 is fixedly connected to the discharge pipe 8 inside the outer shell 2. The edge of the air inlet platform 9 is fixedly connected to the upper end of the outer shell 2. A through cavity 91 is vertically formed at a position near the edge of the air inlet platform 9. An air inlet disc 92 is slidably connected in the through cavity 91 in the vertical direction. A compressed air cavity 22 is fixedly installed on the outer side of the upper end surface of the outer shell 2. An air inlet pipe 221 is connected through the air inlet platform 9 between the compressed air cavity 22 and the discharge pipe 8. A gas blocking groove 2211 is vertically formed in the air inlet pipe 221. A gas blocking pipe 222 is slidably connected in the gas blocking groove 2211 in the vertical direction. An air vent groove 2221 is formed at the position of the lower end of the gas blocking pipe 222 in the air inlet pipe 221. A gas blocking spring 223 is sleeved on the gas blocking pipe 222. The upper and lower ends of the gas blocking spring 223 are respectively fixedly installed on the air inlet pipe 221 and the lower end of the gas blocking pipe 222.

[0061] During the use process, when a large amount of particles are deposited on the filter screen, causing the filter screen to become blocked, at this time, the gas will accumulate inside the outer shell 2, thereby exerting a pushing force on the air inlet disc 92. When the air inlet disc 92 comes into contact with the gas blocking pipe 222, a pushing force will be exerted on the gas blocking pipe 222. When the air vent groove 2221 enters the middle position of the air inlet pipe 221, the compressed air accumulated in the compressed air cavity 22 will enter the discharge pipe 8 and the inside of the filter screen device 73. Under the impact of the compressed air, the impurities accumulated on the filter screen 733 will be effectively cleaned. When the compressed air in the compressed air cavity 22 is used up, under the rebounding action of the gas blocking spring 223, the gas blocking pipe 222 will block the air inlet pipe 221 again. The compressed air cavity 22 is connected to an external air pump, and the external air pump will inject air into the compressed air cavity 22 again.

[0062] As Figure 5 、 Figure 8 and Figure 9 As shown in the figure, a backwashing air mechanism 81 is installed in the discharge pipe 8. A pair of backwashing air mechanisms 81 are symmetrically designed at the position of the discharge pipe 8. The backwashing air mechanism 81 includes a backwashing plate 82, a hinge rod 83, a linkage rod 84, and a vertical slider 85. The hinge rod 83 is hinged to the edge of the discharge pipe 8. Two quarter-circle backwashing plates 82 are symmetrically hinged on the hinge rod 83. The other end of the hinge rod 83 is hinged to a linkage rod 84. A vertical slider 85 is slidably connected in the discharge pipe 8 in the vertical direction. The vertical slider 85 is hinged to the linkage rod 84.

[0063] When the compressed air does not enter the discharge pipe 8, the recoil gas mechanism 81 is in a folded state. When the compressed air enters the discharge pipe 8, due to the violent expansion of the gas, it will have an impact on the recoil plate 82. A block is installed on the discharge pipe 8 corresponding to the recoil plate 82. When the recoil plate 82 contacts the block, the recoil plate 82 will unfold, and when the recoil plate 82 is fully unfolded, the block will resist the upper end of the recoil plate 82. In this way, the recoil plates 82 in the two recoil gas mechanisms 81 will block most of the space in the discharge pipe 8, so that the remaining compressed air will blow the filter screen 733 with greater force, thereby better removing impurities on the filter screen 733.

[0064] like Figure 5 and Figure 6 As shown, first interlocking bevel gears 735 are fixedly installed at both ends of all the filter reels 731, and the first interlocking bevel gears 735 fixedly connected at adjacent positions of the filter reels 731 are commonly meshed with second interlocking bevel gears 736, and the second interlocking bevel gears 736 are rotatably connected to the separation table 71 located above.

[0065] During use, the above-mentioned mechanism can adjust all the filter screens 733 at the same time and only requires one driving source. For example, only one driving motor is needed to drive one of the second interlocking bevel gears 736 that is rotationally connected to the upper separation plate 71, so that all the filter screen reels 731 can rotate synchronously at the same time.

[0066] like Figure 11 As shown, the upper end of the grinding plate 4 is processed with a plurality of arc-shaped pushing strips 42 .

[0067] When the graphite falls into the upper end of the annular roller 3 , with the auxiliary pushing action of the pushing bar 42 , the graphite can fall into the position between the annular roller 3 and the grinding plate 4 more efficiently.

[0068] like Figure 2 As shown, the housing 2 is fixedly provided with a second baffle 23 at the lower end of the first baffle 31 , and the first baffle 31 and the second baffle 23 partially overlap in the vertical direction.

[0069] When the ground graphite falls onto the first baffle 31, the graphite particles will scatter due to the collision and may fall under the baffle and accumulate. By setting the second baffle 23, the graphite particles can be further blocked and a reverse air duct effect can be generated with the edge of the first baffle 31, thereby blowing the graphite particles back to the upper end of the first baffle 31.

[0070] like Figure 2As shown, the first separation device 6 includes a blocking ring 61, the blocking ring 61 is rotatably mounted at the upper end of the inner cavity of the housing 2, a through groove is machined on the side surface of the blocking ring 61, and a plurality of through grooves on the blocking ring 61 are evenly distributed in the circumferential direction.

[0071] During the rotation of the blocking ring 61, the through grooves formed on the blocking ring 61 will not block the entry of air carrying sufficiently refined dust, but will block larger particles that have not been sufficiently milled.

[0072] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", etc. indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation and specific orientation structure and operation. Therefore, it cannot be understood as a limitation to the present invention. In addition, "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0073] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0074] The above has described a detailed description of an embodiment of the present invention, but the content described above is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
