Description

Technical Field

[0001] This utility model relates to the field of filter technology for carbon black production, and more specifically, it relates to a filter for carbon black production. Background Technology

[0002] In existing technologies, carbon black is typically filtered and collected using bag filters. However, this traditional filtration method has several problems in practical applications. First, carbon black, as a nanoscale particulate material with special physicochemical properties, has a large number of active groups and unsaturated bonds on its surface. These characteristics cause strong van der Waals forces and chemical bonds between the carbon black particles and the filter bag fibers. During the filtration process, carbon black particles gradually accumulate on the outer surface of the filter bag, forming a dense adhesion layer. Over time, this adhesion layer thickens, eventually forming a filter cake that is difficult to remove. This adhesion not only requires strong methods such as high-pressure water washing and mechanical knocking to partially remove it, but also leads to a continuous decrease in the air permeability of the filter bag and a significant increase in system operating resistance. More seriously, the residual carbon black that is not completely removed will mix with newly generated carbon black, causing cross-contamination of the product and seriously affecting the purity and quality stability of the final product.

[0003] Secondly, some existing equipment uses pulse airflow cleaning systems, which clean the filter bags by injecting compressed gas into them. While this system improves the cleaning effect to some extent, it still has significant drawbacks. Most current pulse control systems use fixed injection pressures, i.e., fixed gas delivery speeds. This rigid design cannot adapt to changes in operating parameters such as flue gas concentration and particulate load during production. In actual operation, when dealing with high-concentration flue gas, fixed-parameter pulse cleaning often lacks sufficient force, resulting in incomplete cleaning. Under low-load conditions, the same parameter settings can lead to over-cleaning, causing not only a serious waste of compressed air but also accelerating fatigue damage to the filter bags due to frequent impacts, greatly shortening their service life.

[0004] Furthermore, although some improved equipment has achieved airflow speed adjustment by adding simple devices, due to fundamental flaws in the system design, the adjustment mechanism of these devices generally lacks an effective locking and stabilizing device. When high-speed airflow passes through, it will produce obvious vibration. This vibration will be transmitted to the conveying pipe and then to the adjustment device, causing the structure after the flow rate adjustment to shift. This will cause the carefully adjusted airflow parameters to drift, forcing the equipment to be frequently stopped for maintenance and readjustment of parameters, which will seriously affect the continuous and stable operation of the production line.

Multiple shift blocks are movably arranged on one side of the shift sleeve. The control sleeve is rotatably installed on the outside of the intake pipe. Multiple positioning blocks are fixedly installed on the outside of the intake pipe. The large gear is fixedly installed on one side of the control sleeve.

[0010] The present invention is further configured such that a partition is detachably provided in the processing chamber, and a plurality of filter bags are provided in the processing chamber, the filter bags being detachably installed below the partition.

[0015] The present invention is further configured such that both the shifting rail and the shifting groove are T-shaped structures, and the special structure design ensures the precise movement of the shifting block.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a filter for carbon black production, which has the following characteristics:

[0018] Beneficial effects:

[0019] 1. The cleaning device achieves uniform distribution and precise injection of compressed gas through the coordinated operation of the distribution chamber, fixed pipe, and distribution pipe. The distribution chamber, as the transfer hub of the airflow, can stably deliver high-pressure gas to each distribution pipe, ensuring the pressure consistency of the cleaning airflow. The fixed pipe adopts a high-strength pressure-resistant design to effectively avoid pressure loss during airflow transportation. The distribution pipe is rationally arranged along the filter bag arrangement direction, and the multiple spray holes on its side wall form a dense pulse airflow network, making the injection precise. This cleaning structure breaks through the limitations of traditional equipment, making it easier for the carbon black filter adhering to the filter bag surface to fall off. Compared with traditional cleaning methods, this device significantly improves cleaning efficiency, while greatly reducing the filter bag damage rate and effectively extending the service life of the filter bags.

[0020] 2. The speed control device achieves dynamic adjustment of the airflow channel cross-sectional area through the linkage mechanism between the control sleeve and the rotating plate. The angle changes of the rotating plate and multiple sets of flow holes can precisely control the gas flow area. The gear transmission system composed of the driving gear and the driven wheel accurately converts the rotational motion of the control sleeve into changes in the opening and closing angle of the rotating plate. This adjustment mechanism can be adjusted to the optimal cleaning intensity according to the usage requirements: when dealing with high-concentration flue gas, the flow cross-sectional area is increased to increase the airflow speed and ensure effective removal of stubborn carbon black; under low-load conditions, the cross-sectional area is reduced to avoid energy waste caused by excessive cleaning. This device significantly reduces compressed air consumption, while reducing filter bag fatigue damage and improving the flexibility of equipment use.

[0021] 3. The locking mechanism, through its innovative mechanical interlock design, perfectly solves the displacement problem caused by vibration in traditional regulating devices. The precision threaded pair formed by the shift sleeve and the screw, combined with the small gear set driven by the large gear, forms a transmission system with self-locking characteristics. The shift wheel and the positioning block adopt a V-groove fit structure, forming a double locking mechanism under the preload of the shift spring. The shift wheel is ultimately stably limited by the inner wall of the shift sleeve, which can withstand the vibration impact generated by the airflow. The T-shaped shift rail and shift groove form a three-dimensional limiting system, which effectively controls the displacement of the regulating mechanism. This locking structure ensures that the airflow parameters remain stable during long-term operation, completely avoiding the parameter inaccuracies caused by vibration in traditional equipment. At the same time, this mechanism is easy to operate, has high maintenance efficiency, and significantly reduces equipment maintenance costs. Attached Figure Description

Multiple positioning blocks 19 are fixedly installed on the outside of the intake pipe 7. The large gear 20 is fixedly installed on one side of the control sleeve 18. The two ends of the shift spring 21 are respectively connected to two adjacent shift blocks 17. The large gear 20 meshes with multiple pinions 15.

[0032] The processing chamber 1 is detachably provided with an input chamber 22 on one side, and an input pipe 23 is connected to the input end of the input chamber 22. The processing chamber 1 is connected with an output pipe 24 on the other side, and a chamber cover 25 is detachably provided at the top of the processing chamber 1.

[0033] The treatment chamber 1 is provided with a detachable partition 26, and the treatment chamber 1 is provided with multiple filter bags 27, which are detachably installed below the partition 26.

[0034] In this embodiment, when the device is needed, the combusted gas is first delivered to the input pipe 23, and then enters the processing chamber 1 through the input chamber 22. The carbon black adheres to the outside of the filter bag 27, and the filtered gas enters the inside of the filter bag 27. It then flows to the top of the partition 26 and is delivered to the subsequent processing equipment through the output pipe 24 on one side. The external conveying device is then turned on, so that the conveying device delivers the compressed gas to the inlet pipe 7. The compressed gas is then delivered to the distribution chamber 2 through the inlet pipe 7 and the fixed pipe 3. The compressed gas is then distributed to the various distribution pipes 4 through the distribution chamber 2. The pulsed airflow is then delivered to the filter bag 27 through multiple nozzles 5 opened at the bottom of the side wall of the distribution pipe 4, impacting the filter bag 27 and causing the carbon black adhering to the outside of the filter bag 27 to fall off. The carbon black then falls into the collection device connected to the outside of the processing chamber 1.

[0035] Please see Figures 3-5 As a further implementation of the overall equipment: the rotating plate 8 is provided with multiple flow holes 28.

[0036] A shifting wheel 29 is provided on one side of the shifting block 17, and the shifting wheel 29 is engaged between the two positioning blocks 19.

[0037] Multiple shift rails 30 are fixedly provided on one side of the control sleeve 6, and a shift groove 31 is provided in the shift block 17. The shift rails 30 and the shift groove 31 are adapted to each other.

[0038] An mounting plate 32 is fixedly provided on the outside of the air intake pipe 7, and multiple screw sleeves 16 and pinions 15 are rotatably mounted on the mounting plate 32.

[0039] Both the shift rail 30 and the shift groove 31 are designed with a T-shaped structure.

[0040] More specifically, when the delivery speed of the compressed airflow needs to be adjusted according to usage requirements, firstly, the control sleeve 18 is rotated forward. The control sleeve 18 will drive the large gear 20 on one side to rotate forward. Then, the large gear 20 will drive multiple driven wheels 9 meshing with it to rotate in the opposite direction. Then, the driven wheels 9 will drive each screw sleeve 16 to rotate in the opposite direction on the mounting plate 32. Since the screw sleeve 16 and the screw 14 are connected by threads, the screw 14 will drive the shift sleeve 13 to slide, so that the shift sleeve 13 no longer limits the outer side of the shift wheel 29. Then, the control sleeve 6 is rotated, and the control sleeve 6 drives multiple shift rails 30 on one side to rotate. Then, the shift rail 30, in conjunction with the shift groove 31, drives multiple shift blocks 17 to rotate synchronously. The shift blocks 17 then drive the shift wheel 29, which is rotatably mounted on one side, to move out from between the two positioning blocks 19. Simultaneously, the shift wheel 29 drives the shift blocks 17 to slide outward along the shift rail 30 and the shift groove 31, and the shift blocks 17 drive the shift spring 21 to stretch outward. At the same time, the control sleeve 18 drives the inner rotating tube 11 to rotate, causing the rotating tube 11 to drive the active gear 10 at one end to rotate. The active gear 10 then drives each meshing driven wheel 9 to rotate, causing the driven wheels 9 to drive the rotating shaft 12 to rotate. Wheel 9 drives the rotating plate 8 on one side to rotate, changing the angle of the rotating plate 8. Simultaneously, the rotating plate 8 changes the angle of the flow hole 28. The changes in the angles of the flow hole 28 and the rotating plate 8 alter the flow area inside the intake pipe 7, thereby regulating the gas flow rate. Once the gas flow rate is adjusted appropriately, the rotation of the control sleeve 6 stops, and the shift rail 30 and shift groove 31 work together to rotate the shift block 17 between the two corresponding positioning blocks 19. Then, the shift spring 21 resets, pulling the shift block 17 inward along the shift rail 30 and shift groove 31, causing the shift block 17 to engage with the shift wheel 29. The control sleeve 18 is rotated in the opposite direction between the two corresponding positioning blocks 19. This causes the control sleeve 18 to drive the large gear 20 on one side to rotate in the opposite direction. The large gear 20 then drives the small gear 15 meshing with it to rotate synchronously in the forward direction. The small gear 15 then drives the screw sleeve 16 to rotate in the forward direction on the mounting plate 32. The screw 14 then drives the shift sleeve 13 to slide in the opposite direction. This causes the inner wall of the shift sleeve 13 to re-limit the outer wall of the shift wheel 29, preventing the shift wheel 29 and the shift block 17 from sliding outward. This achieves the rotation limit of the control sleeve 6, preventing the control sleeve 6 from rotating and ensuring the structural stability after the flow rate adjustment, thus ensuring the stable use of the equipment.

[0041] In summary, when the equipment is in use or operation: When the equipment is needed, the combusted gas is first delivered to the input pipe 23, and then enters the processing chamber 1 through the input chamber 22. The carbon black will then adhere to the outside of the filter bag 27. The filtered gas will enter the inside of the filter bag 27 and then flow to the top of the partition 26. It will then be delivered to the subsequent processing equipment through the output pipe 24 on one side. Then, the external conveying device is turned on, so that the conveying device delivers the compressed gas to the inlet pipe 7. Then, it is delivered to the distribution chamber 2 through the inlet pipe 7 and the fixed pipe 3. Then, it is distributed to each distribution pipe 4 through the distribution chamber 2. Then, a pulse airflow is formed by multiple nozzles 5 opened at the bottom of the side wall of the distribution pipe 4 and delivered to the filter bag 27 to impact the filter bag 27, causing the carbon black attached to the outside of the filter bag 27 to fall off. Then, the carbon black falls into the collection device connected to the outside below the processing chamber 1.

[0042] When the delivery speed of the compressed airflow needs to be adjusted according to usage requirements, firstly, the control sleeve 18 is rotated forward. The control sleeve 18 will drive the large gear 20 on one side to rotate forward. Then, the large gear 20 will drive multiple driven wheels 9 meshing with it to rotate in the opposite direction. Then, the driven wheels 9 will drive each screw sleeve 16 to rotate in the opposite direction on the mounting plate 32. Since the screw sleeve 16 and the screw 14 are connected by threads, the screw 14 will drive the shift sleeve 13 to slide, so that the shift sleeve 13 no longer limits the outer side of the shift wheel 29. Then, the control sleeve 6 is rotated, and the control sleeve 6 drives multiple shift rails 30 on one side to rotate. The positioning rail 30, in conjunction with the shifting groove 31, drives multiple shifting blocks 17 to rotate synchronously. Then, the shifting blocks 17 drive the shifting wheels 29, which are rotatably mounted on one side, to move outwards from between the two positioning blocks 19. Simultaneously, the shifting wheels 29 drive the shifting blocks 17 to slide outwards along the positioning rail 30 and the shifting groove 31, and the shifting blocks 17 drive the shifting spring 21 to stretch outwards. At the same time, the control sleeve 18 drives the inner rotating tube 11 to rotate, causing the rotating tube 11 to drive the active gear 10 at one end to rotate. The active gear 10 then drives each meshing driven wheel 9 to rotate, causing the driven wheels 9 to drive the rotating shaft 12 to rotate. The driven wheels 9... The rotating plate 8 on one side will rotate, changing its angle. Simultaneously, the rotating plate 8 will change the angle of the flow hole 28. These changes alter the flow area inside the intake pipe 7, thus regulating the gas flow rate. Once the gas flow rate is adjusted appropriately, the control sleeve 6 stops rotating, and the shift rail 30 and shift groove 31 work together to rotate the shift block 17 between the corresponding two positioning blocks 19. Then, the shift spring 21 resets, pulling the shift block 17 inward along the shift rail 30 and shift groove 31, causing the shift block 17 to engage with the shift wheel 29. Between the two positioning blocks 19, the control sleeve 18 is rotated in the opposite direction, causing the control sleeve 18 to drive the large gear 20 on one side to rotate in the opposite direction. Then the large gear 20 will drive the small gear 15 meshing with it to rotate synchronously in the forward direction. Then the small gear 15 will drive the screw sleeve 16 to rotate in the forward direction on the mounting plate 32. Then the screw 14 will drive the shift sleeve 13 to slide in the opposite direction, so that the inner wall of the shift sleeve 13 will limit the outer wall of the shift wheel 29 again, so that the shift wheel 29 and the shift block 17 cannot slide outward, thereby realizing the rotation limit of the control sleeve 6, so that the control sleeve 6 will not rotate, ensuring the structural stability after the flow rate adjustment, and ensuring the stable use of the equipment.
