Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of graphite processing, and particularly relates to a dust collecting device for graphite carbon material production and processing. BACKGROUND

[0002] In the graphite purification process, metal impurities need to be removed by adding acid reaction. After the acid reacts with the metal in the graphite, it is dried by a centrifugal machine and a drying machine, and then is discharged outward by a negative pressure conveying system connected to the drying machine. However, the negative pressure conveying system produces a large amount of graphite dust. At present, a bag dust collector is generally used in the industry to treat such dust. Although a bag dust collector is provided for dust removal, the traditional pulse bag dust collector has the problem of unstable collection efficiency, and the filter bag needs to be frequently replaced, which makes the dust filtration not thorough enough. In addition, the dust contains a large amount of acidic substances, which will pollute the environment if directly discharged into the air.

[0003] Through retrieval, in the patent with the authorization announcement number CN115970427B, a spherical graphite dust collecting system is disclosed. In the system, the alkaline gas sprayed by the atomizing nozzle can be adsorbed by the mesh plate. At the same time, the acidic substances in the gas flow can react with the alkaline substances on the mesh plate during the downward flow of the gas, thereby increasing the contact area of the gas and the alkaline solution and making the reaction of the acidic substances in the gas flow and the alkaline solution more thorough. However, in actual use, in a wet dust removal environment, the alkaline spray is easy to form a viscous mixture with the graphite dust, which can easily block the pores of the activated carbon mesh plate. Especially when the dust concentration is high, the solid matter attached to the mesh plate can quickly fail, resulting in a sharp decrease in adsorption efficiency. In addition, manual cleaning of the blocked mesh plate is not only tedious, but also requires frequent shutdown, which seriously affects the production continuity and overall dust removal efficiency. Based on this, a dust collecting device for graphite carbon material production and processing is proposed. SUMMARY

[0064] Secondly, a fan blade assembly can also be arranged at the lower end of the dust removal box 2, the fan blade assembly comprises a driving motor and fan blades, the fan blades rotate to make the airflow enter the flow guide cylinder 4.

[0066] Referring to Figures 5-6 and Figures 8-9 As shown, the blowing mechanism 8 includes a blowing main pipe 81 which extends coaxially with the honeycomb ceramic filter cartridge 5 into the cavity 52, and a rotatable sealing ring is arranged at the position where the blowing main pipe 81 penetrates the honeycomb ceramic filter cartridge 5, the section of the blowing main pipe 81 located in the dust removal tank 2 is a hard pipe, a plurality of downward nozzles 83 are arranged on the inner section of the blowing main pipe 81, the input end of the blowing main pipe 81 is connected with an alkaline solution tank through a pipeline, and the blowing main pipe 81 is connected with a blowing branch pipe 82, and the blowing main pipe 81 and the blowing branch pipe 82 are both provided with electric control valves, the blowing branch pipe 82 is connected with a blower for conveying air to be blown, a PH sensor is arranged at the lower end of the dust removal tank 2, when the monitored pH value is lower than the set threshold value (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 alkaline solution is sprayed out through the nozzles 83 of the blowing main pipe 81 to be blown, and the residual acidic substances are neutralized at the same time, and the neutralization process continues until the pH value rises to the interval of 7.0-8.0; when the pH value is in the normal range, the PLC controller controls the switching to air blowing, and high-pressure air is sprayed out at high speed through the nozzles 83 to form a flushing airflow in the honeycomb ceramic filter cartridge 5 to blow off the dust attached to the surface of the filter material, which not only realizes the effective cleaning of the honeycomb ceramic filter cartridge 5, but also further reduces the content of acidic substances in the exhaust gas through the secondary neutralization process, so that the emission index reaches more stringent environmental protection standards.

[0067] In addition, a corrosion-resistant pressure monitoring sensor is arranged inside the blowing pipe 81. When the pressure inside the blowing pipe 81 is abnormal and exceeds a set threshold range, the device can be automatically stopped and an alarm is given to ensure the safety of the device operation.

[0068] Referring to Figures 8-12 As shown in the drawings, the first impact part 91 comprises an annular frame 911, a fixed block 912 and a movable strip 913. The annular frame 911 is fixed to the inner wall of the honeycomb ceramic filter cartridge 5 and is rotatably installed outside the blowing pipe 81. The fixed block 912 is fixed on the annular frame 911 and has a mounting groove at the bottom end. A movable block 914 is slidably fitted in the mounting groove. A first spring 915 is connected between the top end of the movable block 914 and the top end of the mounting groove. The movable strip 913 is fixed at the bottom end of the movable block 914 and has a liquid receiving groove. When the honeycomb ceramic filter cartridge 5 rotates, the annular frame 911 drives the fixed block 912 to rotate, and in turn drives the movable strip 913 at the bottom end of the movable block 914 to rotate. The rotation of the movable strip 913 can cross the alkali solution sprayed by the nozzle 83. Through continuous and regular impact action, the original spraying path and flow rhythm of the alkali solution are broken, and more vortex and turbulence are formed in the cavity 52. The alkali solution can more fully contact the inner wall of the cavity 52 and the filter 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 more sufficient action time for the neutralization reaction and the cleaning process. Secondly, under the action of centrifugal force, the movable strip 913 will be subjected to an outward stretching force. The movable strip 913 can stretch and contract under the action of the first spring 915 to dynamically change the outward extension distance of the movable strip 913 in one rotation period, so that the alkali solution in the liquid receiving groove on the movable strip 913 is thrown out. This dynamic stretching and liquid throwing action, on the one hand, increases the secondary neutralization range, and on the other hand, the thrown-out alkali solution has a certain kinetic energy and can form a stronger scouring force on the inner wall of the cavity 52, thereby improving the cleaning effect and reducing the possibility of residual acidic impurities.

[0069] Referring to Figures 8-12As shown, the second impact part 92 includes a column body 921 and a movable rod 922, the column body 921 is fixed at the upper end surface of the movable strip 913, the bottom end of the column body 921 is provided with a groove 924, the movable rod 922 is arranged in the groove 924 in a lifting manner, wherein the bottom end of the column body 921 is provided with the groove 924, the top end of the movable rod 922 and the top end of the groove 924 are connected with the second spring 925, the bottom end of the movable rod 922 is fixed with the pressure ball 923, when the movable strip 913 rotates, the second impact part 92 rotates with the movable strip 913, under the action of centrifugal force, the movable rod 922 provided 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 dynamically changes with the rotating position, when it rotates to the downward position, the downward component force of gravity on the movable rod 922 reaches the maximum value, the component force and the centrifugal force form a superposition effect, so that the outward extension length of the pressure ball 923 at this time reaches the longest state, the pressure ball 923 in the longest extension state can form the maximum knocking force on the inner lower end of the honeycomb ceramic filter cartridge 5, through mechanical vibration, the adhering objects adhered to the inner wall of the filter cartridge are quickly separated, the dust removal efficiency is significantly improved, wherein when the speed increases, the centrifugal force increases, the outward extension amplitude of the movable rod 922 increases, 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, under the reset action of the second spring 925, the movable rod 922 contracts, and the knocking force decreases, dynamic adjustment enables the pressure ball 923 to knock the inner wall of the filter cartridge with periodically changing force, while ensuring the cleaning effect, the mechanical damage to the honeycomb ceramic filter cartridge 5 body is minimized, and the service life of the filter cartridge is prolonged.

[0070] Through the above, in actual use, the cloth bag dust collector 1 filters the airflow into the dust removal box 2, the atomizing nozzle 32 sprays alkaline mist into the flow guide cylinder 4, the acidic substances and the alkaline mist react, thereby reducing the emission of acidic gas into the air, the airflow moves downward through the flow guide cylinder 4 and is dynamically purified by the honeycomb ceramic filter cartridge 5, wherein the honeycomb ceramic filter cartridge 5 is in a continuous rotating process, cooperates with the follow-up impact part 9 composed of the sweeping mechanism 8 and the first impact part 91 and the second impact part 92, and cooperates with the follow-up impact part 9, through multi-dimensional cooperative cleaning, the solid objects continuously adhered to the honeycomb ceramic filter cartridge 5 can be removed in real time, the pores of the honeycomb ceramic filter cartridge 5 are always kept unobstructed, not only the honeycomb ceramic filter cartridge 5 can maintain good purification efficiency for a long time, avoid the decrease of filtration area and the decrease of purification effect caused by the accumulation of solid objects, but also the stable passability can be ensured, the increase of system resistance caused by blockage is reduced, and the energy consumption of the equipment is reduced.

[0071] In addition, the dynamic blockage removal is completely automatic, does not need to be periodically disassembled and cleaned manually, greatly reduces the labor cost investment and equipment downtime, even in the working condition of continuous production, it can also play a stable role, effectively meets the needs of continuous operation of equipment in industrial production.

[0072] Embodiment Two:

[0073] Referring to Figures 1-7 As shown in the figure, this embodiment is an extension based on Embodiment One. The dust collecting device for graphite carbon material production and processing further comprises a follow-up backslap mechanism 7 connected to the rotating mechanism 6 and extending to the inside upper end of the dust removal box 2. When the rotating mechanism 6 is in action, the follow-up backslap mechanism 7 periodically floats up and down to impact the downwardly sprayed alkaline solution to prolong the residence time.

[0074] Referring to Figures 3-7 As shown in the figure, the follow-up backslap mechanism 7 comprises a slapping strip 71, a first gear 73 and a third gear 76. The slapping strip 71 penetrates the inside upper end of the dust removal box 2 along the length direction of the dust removal box 2. The first gear 73 is meshingly connected to the driving gear 62. The end of the honeycomb ceramic filter cartridge 5 away from the connecting ring 51 is connected to a second gear 75 through a connecting shaft. The third gear 76 is meshingly connected to the second gear 75. The first gear 73 and the third gear 76 are both eccentrically connected to a hinged strip 72. The top end of the hinged strip 72 is fixed with a sleeve strip 74. The sleeve strip 74 is provided with a movable slot 741. The end of the slapping strip 71 penetrates the corresponding movable slot 741. When the motor 61 drives the driving gear 62 to rotate, the first gear 73 meshingly connected to the driving gear 62 rotates synchronously with the driving gear 62 when the honeycomb ceramic filter cartridge 5 rotates. At the same time, the second gear 75 and the third gear 76 on the other side also rotate synchronously, which can drive the eccentrically connected hinged strip 72 to orderly ascend and descend. In this way, the slapping strip 71 can be orderly lifted and lowered through the sleeve strip 74 provided with the movable slot 741. When the slapping strip 71 moves upward, it will form a repulsion effect on the downwardly sprayed alkaline solution, so that part of the originally downward flowing alkaline solution changes its movement direction and moves upward. The upward movement of the alkaline solution prolongs its residence time at the inside upper end of the dust removal box 2, so that the alkaline solution has more sufficient contact time with the acidic substances in the dust removal box 2, which can more effectively play the roles of neutralization, adsorption and the like, and improve the overall dust removal effect. At the same time, the prolonged residence time is also helpful for the alkaline solution to be more evenly distributed in the dust removal space, avoiding the alkaline solution deficiency in local areas and affecting the dust removal efficiency.

[0075] Referring to Figures 3-4As shown, the vertical through hole is provided at the position where the beating bar 71 penetrates the dust removal box 2, and the corrugated sealing strip 10 is arranged between the top end of the through hole and the upper end surface of the beating bar 71 and between the bottom end of the through hole and the lower end surface of the beating bar 71. The corrugated sealing strip 10 is flexible, and when the beating bar 71 moves upward, the corrugated sealing strip 10 between the top end of the through hole and the upper end surface of the beating bar 71 is compressed and shrinks, and at the same time, the corrugated sealing strip 10 between the bottom end of the through hole and the lower end surface of the beating bar 71 is stretched and elongated. When the beating bar 71 moves downward, the situation is opposite, the upper corrugated sealing strip 10 is elongated, and the lower corrugated sealing strip 10 is shrunk. The flexible deformation with the lifting of the beating bar 71 ensures that the corrugated sealing strip 10 is in close contact with the corresponding surfaces of the beating bar 71 and the through hole during the lifting movement of the beating bar 71, which can effectively ensure the sealing performance of the through hole, prevent the leakage of lye and the like, and avoid the waste of resources and the pollution to the external environment of the dust removal box 2.
