Description

Technical Field

[0001] The present invention relates to the technical field of graphite processing, in particular to a dust collecting device for producing and processing graphite carbon materials. Background Art

[0002] In the graphite purification process, it is necessary to remove metal impurities through acid reaction. After the acid reacts with the metal in the graphite, it is dried by a centrifuge and a dryer, and then discharged to the outside by a negative pressure conveying system connected to the dryer. However, the negative pressure conveying system will generate a large amount of graphite dust. At present, bag dust collectors are generally used in the industry to deal with this type of dust. Although bag dust collectors are equipped for dust removal, traditional pulse bag dust collectors have the problem of unstable collection efficiency, and the filter bags need to be replaced frequently, which makes the dust filtration not thorough enough. Secondly, these dusts contain a large amount of acidic substances. If they are directly discharged into the air, they will pollute the environment.

[0003] After searching, a patent with authorization announcement number CN115970427B discloses a spherical graphite dust collection system, in which the alkaline gas sprayed from the atomizing nozzle can be adsorbed through the mesh plate. At the same time, in the process of the gas flowing downward through the mesh plate, the acidic substances in the airflow can react with the alkaline substances on the mesh plate, thereby increasing the contact area between the gas and the alkaline solution, making the acidic substances in the airflow and the alkaline solution react more thoroughly. However, in actual use, in a wet dust removal environment, the alkaline spray and graphite dust combine to form a viscous mixture, which can easily clog the pores of the activated carbon mesh plate; especially when the dust concentration is high, the solid matter attached to the mesh plate will quickly fail, resulting in a sharp drop in adsorption efficiency. In addition, manual cleaning of the clogged mesh plate is not only cumbersome, but also requires frequent shutdowns, which seriously affects production continuity and overall dust removal efficiency. Based on this, a dust collection device for the production and processing of graphite carbon materials is proposed. Summary of the Invention

[0023] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary persons in this field without making creative work are within the scope of protection of the present invention. The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described here. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to be able to fully convey the scope of the present invention to those skilled in the art.

[0024] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] Example 1: See Figures 1-6 as well as Figures 8-12As shown, the present invention proposes a dust collection device for the production and processing of graphite carbon materials, comprising a bag dust collector 1 and a dust box 2 connected by a pipeline. After the graphite is dusted by the bag dust collector 1, the air flow with dust enters the dust box 2, and the dust in the air flow is purified in the dust box 2 to reduce the emission of dust and acidic gas into the air, thereby reducing environmental pollution. The upper end of the dust box 2 is connected to an atomizing mechanism 3, wherein the atomizing mechanism 3 includes a water spray pipe 31 provided at the top of the dust box 2, and the water spray pipe 31 is connected to a plurality of atomizing nozzles 32 extending to the top of the dust box 2. The input end of the water pipe 31 is connected to a water tank (not shown) through a corrosion-resistant pipe. The water tank is filled with an alkaline solution. A corrosion-resistant pump body can be provided to suck and transport the alkaline solution. The water spray pipe 31 and the atomizing nozzle 32 are made of corrosion-resistant alloy materials and can withstand long-term corrosion from the alkaline solution. The alkaline solution in the water mist sprayed by the atomizing nozzle 32 reacts with the acidic dust in the dust removal box 2 to neutralize the acidic impurities in the dust. Secondly, the water mist contacts the dust in the air flow and condenses together to form a viscous substance, thereby achieving the dust removal effect. A slag discharge port and a water drain port are also provided at the bottom end of the dust removal box 2.

[0026] In addition, the dust collection device for the production and processing of graphite carbon materials also includes a guide tube 4, a rotating mechanism 6, a purge mechanism 8 and a follower impact piece 9. The guide tube 4 is fixedly arranged inside the dust removal box 2. The guide tube 4 is designed with large upper and lower openings and a small middle. A honeycomb ceramic filter cartridge 5 arranged and rotatable along its length is installed in the guide tube 4. The surface of the honeycomb ceramic filter cartridge 5 can be loaded with an alkaline catalyst (such as calcium hydroxide). The honeycomb ceramic filter cartridge 5 is arranged in the middle of the guide tube 4, and the guide tube 4 can be divided into two or more vertical flow channels. A honeycomb ceramic filter cartridge 5 is arranged in a flow channel, and the middle space of the flow channel just accommodates a rotatable honeycomb ceramic filter cartridge 5. The honeycomb ceramic filter cartridge 5 is cylindrical, and a cavity 52 is formed inside the honeycomb ceramic filter cartridge 5. The output end of the rotating mechanism 6 is transmission-connected to the honeycomb ceramic filter cartridge 5. It is also used to drive the honeycomb ceramic filter cartridge 5 to rotate around its own axis to continuously switch positions for dust removal. The purge end of the purge mechanism 8 extends axially into the cavity 52 and is used to synchronously spray alkali solution downward for purge during the rotation of the honeycomb ceramic filter cartridge 5 to separate the blocked mixture from the honeycomb ceramic filter cartridge 5, so that the honeycomb ceramic filter cartridge 5 can be rotated to an upward position with a better dust removal effect. The follower impact member 9 includes a first impact portion 91 and a second impact portion 92. The follower impact member 9 is arranged between the purge mechanism 8 and the inner wall of the honeycomb ceramic filter cartridge 5. When the rotating mechanism 6 drives the honeycomb ceramic filter cartridge 5 to rotate, the follower impact member 9 rotates synchronously to periodically impact the liquid flow blown out by the purge mechanism 8 through the first impact portion 91, and at the same time, the inner lower end of the honeycomb ceramic filter cartridge 5 is knocked through the second impact portion 92 under the combined action of centrifugal force and gravity.

[0027] Secondly, a fan blade assembly can also be provided at the lower end of the dust removal box 2 . The fan blade assembly includes a drive motor and fan blades. The fan blades rotate to allow the airflow to enter the guide tube 4 .

[0028] Among them, see Figure 3-Figure 6 As shown, the rotating mechanism 6 includes a motor 61, a driving gear 62 is installed at the output end of the motor 61, and a connecting ring 51 is fixed to one end of the honeycomb ceramic filter cartridge 5. The connecting ring 51 is made of corrosion-resistant metal material. The connecting ring 51 can rotatably penetrate the outer shell of the dust removal box 2. Two honeycomb ceramic filter cartridges 5 are provided in the figure. The two honeycomb ceramic filter cartridges 5 are connected by an annular strip so that they can rotate synchronously. A rotatable sealing ring is provided at the place where the connecting ring 51 penetrates the outer shell of the dust removal box 2. The sealing ring is made of wear-resistant and well-sealed rubber material, and its inner side is tightly fitted with the outer surface of the connecting ring 51. The outer side is fixedly connected to the outer shell of the dust removal box 2, which can effectively prevent the dust inside the dust removal box 2 from leaking out while ensuring the smooth rotation of the connecting ring 51. It also prevents the outside air from entering the box without being treated, ensuring the sealing of the dust removal system. A gear ring 63 is fixed to the outside of the connecting ring 51, and the gear ring 63 is meshed with the driving gear 62. By starting the motor 61, the output end of the motor 61 can be used to drive the driving gear 62 to rotate. The rotation of the driving gear 62 drives the meshing gear ring 63 to rotate, so that the two honeycomb ceramic filter cartridges 5 can achieve stable and synchronous rotation under the linkage action of the annular strips.

[0029] See Figure 5-Figure 6 as well as Figure 8-Figure 9As shown, the purge mechanism 8 includes a purge main pipe 81, which extends coaxially with the honeycomb ceramic filter cartridge 5 into the cavity 52, and a rotatable sealing ring is also provided at the part where the purge main pipe 81 passes through the honeycomb ceramic filter cartridge 5, and the section of the purge main pipe 81 located inside the dust removal box 2 is a hard pipe, and a plurality of downward nozzles 83 are installed on the internal section of the purge main pipe 81. The input end of the purge main pipe 81 can be connected to the alkaline solution tank through a pipeline, and a purge branch pipe 82 is connected to the purge main pipe 81, and the purge branch pipe 82 and the purge main pipe 81 are both equipped with electric control valves. The purge branch pipe 82 can be connected to a blower for conveying air for purge, wherein a pH sensor can be installed at the lower end of the dust removal box 2 to monitor the pH value below the set threshold. When the pH value is within the normal range (usually 6.5), the PLC controller (not shown) automatically closes the electric control valve of the branch pipe and opens the electric control valve of the main pipe. The alkali solution is sprayed out through the nozzle 83 of the purge main pipe 81 for purging. During the purging, it reacts with the residual acidic substances. The neutralization process continues until the pH value returns to the range of 7.0-8.0. When the pH value is within the normal range, the PLC controller controls the switch to air purging. High-pressure air is sprayed out at high speed through the nozzle 83, forming a flushing airflow inside the honeycomb ceramic filter cartridge 5, blowing off the dust attached to the surface of the filter material. This design not only achieves effective cleaning of the honeycomb ceramic filter cartridge 5, but also further reduces the acidic substance content in the exhaust gas through the secondary neutralization process, so that the emission indicators meet more stringent environmental protection standards.

[0030] In addition, a corrosion-resistant pressure monitoring sensor is provided inside the purge pipe 81. When the pressure inside the purge pipe 81 is abnormal and exceeds the set threshold range, the machine can automatically shut down and alarm to ensure the safe operation of the equipment.

[0031] See Figures 8-12As shown, the first impact part 91 includes an annular frame 911, a fixed block 912 and a movable bar 913. The annular frame 911 is fixed to the inner wall of the honeycomb ceramic filter cartridge 5, and the annular frame 911 is rotatably mounted on the outside of the purge main pipe 81. The fixed block 912 is fixed on the annular frame 911, and the bottom end of the fixed block 912 is provided with a mounting groove, and a movable block 914 is slidably fitted in the mounting groove. A first spring 915 is connected between the top of the movable block 914 and the top of the mounting groove. The movable bar 913 is fixed to the bottom end of the movable block 914, and a liquid receiving groove is provided on the movable bar 913. When the honeycomb ceramic filter cartridge 5 rotates, the fixed block 912 is driven to rotate by the annular frame 911, and then the movable bar 913 at the bottom end of the movable block 914 is driven to rotate. The rotation of the movable bar 913 can intersect with the alkali solution sprayed from the nozzle 83, and the original alkali solution is broken through continuous and regular impact action. The injection path and flow rhythm allow the alkali solution to form more eddies and turbulences in the cavity 52, which can make the alkali solution more fully contact the inner wall of the cavity 52 and the filtering structure of the honeycomb ceramic filter cartridge 5, thereby significantly increasing the residence time of the alkali solution in the cavity 52, and striving for a more sufficient action time for the neutralization reaction and cleaning process. Secondly, under the action of centrifugal force, the movable bar 913 will be subjected to an outward stretching force. Under the action of the first spring 915, the movable bar 913 can be expanded and contracted to dynamically change the outward extension distance of the movable bar 913 within a rotation cycle, so that the alkali solution in the liquid receiving tank on the movable bar 913 is thrown out. This dynamic expansion and contraction and liquid throwing action, on the one hand, increases the secondary neutralization range. On the other hand, the alkali solution thrown out has a certain kinetic energy, which can form a stronger flushing force on the inner wall of the cavity 52, thereby improving the cleaning effect and reducing the possibility of residual acidic impurities.

[0032] See Figures 8-12As shown, the second impact part 92 includes a column 921 and a movable rod 922, the column 921 is fixed to the upper end surface of the movable bar 913, and a groove 924 is provided at the bottom end of the column 921. The movable rod 922 can be lifted and lowered in the groove 924, wherein a groove 924 is provided at the bottom end of the column 921, and a second spring 925 is connected between the top end of the movable rod 922 and the top end of the groove 924. A pressure ball 923 is fixed to the bottom end of the movable rod 922. When the movable bar 913 rotates, the second impact part 92 rotates accordingly. Under the action of centrifugal force, the movable rod 922 equipped with the pressure ball 923 will extend outward. It is worth noting that the outward extension length of the pressure ball 923 is not a constant value, but changes dynamically with the rotation position. When it rotates to the downward position, the downward component force generated by gravity on the movable rod 922 reaches a maximum value. This component force The superimposed effect formed with the centrifugal force makes the extended length of the pressure ball 923 reach the longest state at this time. The pressure ball 923 in the longest extended state can form the maximum knocking force on the lower end of the inner part of the honeycomb ceramic filter cartridge 5, and promotes the attachments attached to the inner wall of the filter cartridge to quickly detach through mechanical vibration, thereby significantly improving the cleaning efficiency. Among them, when the speed increases, the centrifugal force increases accordingly, and the extended amplitude of the movable rod 922 increases accordingly, and the knocking force of the pressure ball 923 on the inner wall of the honeycomb ceramic filter cartridge 5 is enhanced; when the speed decreases, the centrifugal force decreases, and under the reset action of the second spring 925, the movable rod 922 contracts and the knocking force is weakened. The dynamic adjustment enables the pressure ball 923 to knock on the inner wall of the filter cartridge with a periodically changing force, while ensuring the cleaning effect, minimizing the mechanical loss to the honeycomb ceramic filter cartridge 5 body and extending the service life of the filter cartridge.

[0033] Through the above, in actual use, the airflow after filtering by the bag dust collector 1 enters the dust removal box 2, and the atomizing nozzle 32 sprays alkaline water mist into the guide tube 4, so that the acidic substance and the alkaline spray react, thereby reducing the emission of acidic gas into the air, and the airflow moves downward through the guide tube 4, and is dynamically purified by the honeycomb ceramic filter cartridge 5, wherein the honeycomb ceramic filter cartridge 5 is in a continuous rotation process, and cooperates with the follower impact member 9 composed of the purge mechanism 8 and the first impact part 91 and the second impact part 92. Through multi-dimensional coordinated cleaning, the solid matter constantly attached to the honeycomb ceramic filter cartridge 5 can be removed in real time, so that the pores of the honeycomb ceramic filter cartridge 5 are always kept unobstructed, which not only enables the honeycomb ceramic filter cartridge 5 to maintain good purification efficiency for a long time, avoids the reduction of the filtration area and the decline of the purification effect due to the accumulation of solid matter, but also ensures stable passability, reduces the increase in system resistance caused by blockage, and reduces equipment energy consumption.

[0034] In addition, the dynamic blockage clearing system is fully automated and does not require manual disassembly and cleaning on a regular basis, significantly reducing labor costs and equipment downtime. Even under continuous production conditions, it can function stably, effectively meeting the demand for continuous operation of equipment in industrial production.

[0035] Example 2: See Figure 1-Figure 7 As shown, this embodiment is extended on the basis of the first embodiment. The dust collection device for the production and processing of graphite carbon materials also includes a follow-up return mechanism 7, which is connected to the rotating mechanism 6 and extends to the inner upper end of the dust removal box 2. When the rotating mechanism 6 is in motion, the follow-up return mechanism 7 floats up and down periodically to impact the alkali solution sprayed downward to extend the residence time.

[0036] See Figure 3-Figure 7 As shown, the follow-up slapping mechanism 7 includes a slapping bar 71, a first gear 73 and a third gear 76. The slapping bar 71 passes through the upper end of the dust box 2 along the length direction of the dust box 2. The first gear 73 is meshed and connected to the driving gear 62. The end of the honeycomb ceramic filter cartridge 5 away from the connecting ring 51 is connected to the second gear 75 through the connecting shaft. The third gear 76 is meshed and connected to the second gear 75. The first gear 73 and the third gear 76 are eccentrically connected to the hinged bar 72. The top of the hinged bar 72 is fixed with a sleeve strip 74. The sleeve strip 74 is provided with a movable groove 741. The end of the slapping bar 71 passes through the corresponding movable groove 741, and the driving gear 62 is driven to rotate at the output end of the motor 61, so that when the honeycomb ceramic filter cartridge 5 rotates, it is synchronized with the first gear 73 meshed with the driving gear 62. The second gear 75 and the third gear 76 on the other side rotate synchronously, and the eccentrically connected hinged bar 72 can be driven to rise and fall in an orderly manner, that is, the sleeve bar 74 provided with a movable groove 741 can be used to drive the slapping bar 71 to rise and fall in an orderly manner. When the slapping bar 71 moves upward, it will form an exclusion effect on the alkali liquid sprayed downward, causing part of the alkali liquid that originally flowed downward to change its direction of movement and move upward. The upward movement of the alkali liquid prolongs its residence time at the upper end of the dust removal box 2, so that the alkali liquid has a more sufficient contact time with the acidic substance in the dust removal box 2, and can more effectively play the role of neutralization, adsorption, etc., thereby improving the overall dust removal effect. At the same time, the extended residence time also helps the alkali liquid to be more evenly distributed in the dust removal space, avoiding insufficient alkali liquid in local areas and affecting the dust removal efficiency.

[0037] See Figure 3-Figure 4As shown, a vertical through hole is provided at the place where the slapping bar 71 passes through the dust removal box 2, and a corrugated sealing strip 10 is provided between the top of the through hole and the upper end surface of the slapping bar 71 and between the bottom of the through hole and the lower end surface of the slapping bar 71. The corrugated sealing strip 10 is retractable. When the slapping bar 71 moves upward, the corrugated sealing strip 10 between the top of the through hole and the upper end surface of the slapping bar 71 will be squeezed and contracted. At the same time, the corrugated sealing strip 10 between the bottom of the through hole and the lower end surface of the slapping bar 71 will be stretched and extended. long; when the slapping bar 71 moves downward, the situation is the opposite, the corrugated sealing strip 10 at the upper end is extended, and the corrugated sealing strip 10 at the lower end is contracted. This flexible deformation caused by the lifting and lowering of the slapping bar 71 ensures that during the lifting and lowering movement of the slapping bar 71, the corrugated sealing strip 10 always maintains close contact with the corresponding surfaces of the slapping bar 71 and the through hole, which can effectively ensure the sealing of the through hole, prevent the leakage of alkali solution, etc., and avoid waste of resources and pollution to the external environment of the dust removal box 2.
