Description

Technical Field

[0001] The utility model belongs to the technical field of graphite powder packaging, and particularly relates to a dust removal device for graphite powder packaging. Background Art

[0002] Graphite powder is made by mechanically crushing graphite. According to the degree of crushing, it can be divided into ultrafine graphite powder, nano graphite powder, etc. Graphite powder particles can be used to make thermal conductive paste, high thermal conductivity plastics, electrodes and refractory materials. The mesh number of graphite powder indicates the size of graphite powder particles. The larger the mesh number, the finer the particles. Graphite powders of different mesh numbers are suitable for different applications. The mesh number of graphite powder is generally between 60 mesh and 20,000 mesh. For example, the particle size of 200 mesh is about 74um or 0.074 mm, and the particle size of 10,000 mesh ultrafine graphite powder is about 1.3um. The dried graphite powder is generally packaged by a packaging machine. The graphite powder is black and gray. Graphite dust is easy to float out during the packaging process. After long-term use, it is easy to form a black ground around the packaging ground, which is poor in appearance and dusty.

[0037] In the embodiments of the present invention, referring to Figure 4 and Fig.11 As shown, Fig.11 is a schematic diagram of an embodiment of the airflow direction, Fig.11The solid black arrow in the figure is an example of the direction of air flow. The air flow in the room frame 1 of the schematic diagram of the embodiment of the utility model flows from top to bottom. The air outside the room frame 1 enters the room frame 1 from the air inlet valve 3 at its upper part. The air flow in the room frame 1 passes through the ground grate 21 and enters the ground cavity 2. The dust in the room frame 1 can fall into the dust absorbing liquid 22, so that the dust in the room frame 1 can be quickly dropped and the dust content in the room frame 1 can be quickly reduced. The air flow entering the ground cavity 2 will be blocked by the plug-in sealing plate 7 at the lower end of the plug-in sealing plate 7. The dust collecting liquid 22 flows through and comes into full contact with the dust collecting liquid 22, and the dust collecting liquid 22 will purify the dust carried in the airflow again. The purified airflow will flow out from the flow-through square hole 61 of the plug-in plate 6 to the cleaning trough 5; when the airflow in the cleaning trough 5 flows through the exhaust chamber 8, it will pass through the plug-in plate 6 and the plug-in sealing plate 7 arranged therein and the dust collecting liquid 22 in the exhaust chamber 8 for purification again, so as to ensure that the dust content in the gas discharged from the exhaust chamber 8 and the exhaust fan 9 is effectively reduced, and the exhaust pipe 91 outside the exhaust fan 9 can be connected to the exhaust pipe of the workshop. During the entire circulation process of the airflow, the dust in the chamber frame 1 will be accumulated in the dust absorbing liquid 22, and the dust in the chamber frame 1 will not be raised, so that the rapid dust reduction effect in the chamber frame 1 can be achieved, and the dust absorbing liquid 22 in the ground cavity 2 at the bottom of the chamber frame 1 can filter the airflow, so that the dust carried in the airflow is adsorbed, and the dust collection is convenient, which effectively ensures that the dust generated when the packaging machine encapsulates graphite powder can be quickly eliminated. The external ground 14 of the chamber frame 1 is clean and tidy, and the ground 14 formed by the ground grate 21 on the surface of the interior of the chamber frame 1 is dust-free and tidy, avoiding a large area of ​​dark ground, and the visual aesthetics is better.

[0038] Example 2

[0039] Reference Figures 1 to 11As shown, the top of the inner side of the room frame 1 can be evenly installed with spray heads 13. When the dust in the room frame 1 is large, the water mist sprayed by the spray head 13 can be used to quickly reduce dust, thereby enhancing the effect of rapid dust reduction. The bottom of the ground cavity 2 and the bottom of the dust filter cavity 4 can be inclined to the upper edge of the cleaning trough 5. When cleaning dust, after the hole-inserting plate 6 and the plug-in sealing plate 7 are pulled out, the dust-carrying dust-absorbing liquid 22 can flow into the cleaning trough 5, and after the ground grate 21 is picked up, the sludge at the bottom of the ground cavity 2 can be easily pushed and scraped into the cleaning trough 5 with tools such as shovels in the room frame 1, and the cleaning is extremely convenient and quick; the sludge in the exhaust cavity 8 on the right side of the cleaning trough 5 is cleaned in the same way as in the ground cavity 2. When the hole-inserting plate 6 and the plug-in sealing plate 7 are pulled out, the sludge can be quickly scraped into the cleaning trough 5 using tools. The cleaning trough 5 can be quickly lifted out by the crane in the workshop through the lifting arms 52 on both sides.

[0040] Reference Figure 4 , Figure 6 and Figure 7 As shown, a flap 53 is provided at the bottom of the cleaning trough 5, one end of the flap 53 is connected to the cleaning trough 5 in a hinged rotational manner, and the other end of the flap 53 can be locked and connected to the cleaning trough 5 by bolts. When the bolts are removed, the flap 53 can be opened in a hinged rotational manner, so that the materials in the cleaning trough 5 can be quickly unloaded, which is convenient for the quick unloading operation of the cleaning trough 5. When the flap 53 closes the bottom of the cleaning trough 5, it can be sealed by a sealing strip. Each sealing point can be sealed in the form of a sealing strip.

[0041] Specifically, when the cleaning trough 5 is put back into the dust filter chamber 4 after cleaning, a liquid replenishing hole 531 may be provided on the flap 53 at the bottom of the cleaning trough 5, and the liquid replenishing hole 531 is in the shape of a through hole on the flap 53, but a soft cover rubber plate 532 may be provided at the upper end of the liquid replenishing hole 531 on the inner side of the flap 53, and the soft cover rubber plate 532 may be a rubber plate with a thickness of 2mm to 8mm, and one end of the soft cover rubber plate 532 is connected to the flap 53 by bolts. When the cleaning trough 5 is lowered into the dust filter chamber 4, if there is liquid in the dust filter chamber 4, it can enter the cleaning trough 5 through the liquid replenishing hole 531. At this time, the soft cover rubber plate 532 is in a spiral shape; when the cleaning trough 5 is placed at the bottom of the dust filter chamber 4, the soft cover rubber plate 532 is attached to the flap 53 due to gravity and blocks the liquid replenishing hole 531, ensuring that no leakage will occur at the liquid replenishing hole 531 when the cleaning trough 5 is lifted up after being filled with sludge materials again.

[0042] Example 3

[0043] As an example, Figure 1 , Figure 4 and Fig.10 As shown, a splash-proof grate plate 81, a cone mesh core 82 and a filter screen 83 may be sequentially arranged between the exhaust chamber 8 and the exhaust fan 9. The number of the splash-proof grate plates 81 may be multiple, and the splash-proof grate plates 81 may be in the shape of a grate, and the multiple splash-proof grate plates 81 may be distributed on both sides of the pipe above the liquid surface of the exhaust chamber 8. When the airflow passes through the exhaust chamber 8, the splashing water can be blocked by the multiple inclined splash-proof grate plates 81. The cone mesh core 82 is in the shape of a cone formed by multiple layers of fine white steel mesh. The cone mesh core 82 can block the water droplets in the airflow again, and the airflow can also be filtered again through the air filter of the filter screen 83 above the cone mesh core 82, to ensure the reduction of the moisture content of the water liquid in the airflow, and to ensure the long-term stable operation of the exhaust fan 9.

[0044] Example 4

[0045] Reference Figures 1 to 5 As shown, the air inlet valve 3 may include a top cap 31, an air inlet pipe port 32, an elastic ash support cylinder 33, a middle support body 34 and a turbulent impeller 35. The top cap 31 can be placed above the air inlet pipe port 32 in the form of a support rod for shielding, and the top cap 31 can prevent water and objects from falling into the air inlet pipe port 32; the elastic ash support cylinder 33 is arranged below the air inlet pipe port 32, and the elastic ash support cylinder 33 is in the shape of a main body with an opening on the top, and the diameter of the elastic ash support cylinder 33 is larger than the outer diameter of the air inlet pipe port 32, and the elastic ash support cylinder 33 is sleeved on the outside of the air inlet pipe port 32; the lower end of the elastic ash support cylinder 33 is provided with an integral center rod 331, and the middle support body 34 is a rod-shaped body divided into three equal parts and welded to the inside of the air inlet valve 3. The center rod 331 at the lower end of the ash support cylinder 33 is slidably connected with the center hole of the middle support body 34. A column spring 332 is arranged on the outside of the center rod 331 of the elastic ash support cylinder 33. The elastic ash support cylinder 33 is placed on the middle support body 34 through the column spring 332. The elastic ash support cylinder 33 does not touch the air inlet pipe port 32, thereby ensuring that the airflow passes through the air inlet pipe port 32 and smoothly enters the interior of the air inlet valve 3; the turbulent impeller 35 is in the shape of a small impeller, and the turbulent impeller 35 is rotatably connected with the middle support body 34. When the airflow passing through the interior of the air inlet valve 3 passes through the turbulent impeller 35, the turbulent impeller 35 will be driven by the airflow to rotate, thereby ensuring that the airflow entering the chamber frame 1 from the air inlet valve 3 becomes more dispersed. At the same time, the number of the air inlet valves 3 can be multiple, and the multiple air inlet valves 3 are evenly arranged on the top of the chamber frame 1, ensuring that the airflow entering the chamber frame 1 through the multiple air inlet valves 3 covers the top of the chamber frame 1 more evenly, thereby improving the dust reduction effect in the chamber frame 1.
