Description

Technical Field

[0001] This utility model relates to the technical field of carbon dust collection, and in particular to a dust collection device for a carbon production line. Background Technology

[0002] Carbon production lines generate a large amount of dust, which, when released into the atmosphere, causes pollution. Chinese utility model patent CN220495958U discloses a carbon dust collection and purification device. This device includes a support frame, a purification tank fixedly mounted on the top of the support frame, a support plate fixedly mounted on one side of the support frame, a fume extractor fixedly mounted on the top of the support plate, a smoke inlet pipe fixedly mounted on one side of the fume extractor, and a smoke delivery pipe fixedly mounted on the other side of the fume extractor. One end of the smoke delivery pipe is located inside the lower part of the purification tank. This carbon dust collection and purification device, through the arrangement of spray pipes and spray heads, can cool down asphalt fumes and remove easily water-soluble impurities from the fumes, thus achieving a cooling effect.

[0003] However, the dust collection equipment mentioned above cools the dust by spraying cooling water mist. Since the dust rises with the flue gas and the cooling water mist falls for a short time, the contact time between the dust and the cooling water mist is short, resulting in poor cooling effect and poor adsorption effect on water-soluble impurities. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a dust collection device for a carbon production line that employs two cooling cycles, extends the cooling path and time of flue gas, and improves the cooling effect and the adsorption effect of impurities.

[0005] This utility model discloses a dust collection device for a carbon production line, comprising a frame, a fume extractor, and a collection box. The fume extractor and collection box are mounted on the frame, with the fume extractor located below the collection box. The collection box has an internal collection chamber. It also includes a smoke delivery pipe, a smoke distribution box, a lower sealing plate, and two sealing rings. The lower end of the smoke delivery pipe is connected to the smoke outlet of the fume extractor, and the upper end of the smoke delivery pipe extends into the lower part of the collection chamber of the collection box. The smoke distribution box has an internal distribution chamber, an insertion hole in the center of its bottom, and multiple air outlets at its bottom. The upper end of the smoke delivery pipe is movably inserted... The cigarette delivery pipe is inserted into the socket of the cigarette box. A wear-resistant sealing ring is installed between the outer wall of the cigarette delivery pipe and the socket of the cigarette box. The upper end of the cigarette delivery pipe is located in the middle of the distribution chamber of the cigarette box. The lower sealing plate is fitted onto the outer wall of the cigarette delivery pipe and is located below the cigarette box. Two matching sealing rings are installed on the upper edge of the lower sealing plate and the lower edge of the cigarette box. Matching magnetic blocks are installed on the bottom of the lower sealing plate and the cigarette box. Cooling water is added to the collection chamber of the collection box, submerging the cigarette box. When dust collection is not in operation, the weight of the cigarette box is greater than the buoyancy, and the dust flows out from the collection chamber. The cloth cigarette box descends along the smoke delivery pipe, causing its bottom to magnetically attach to the lower sealing plate. The two sealing rings seal the multiple vents of the cloth cigarette box. During operation, the exhaust fan draws in the flue gas generated by the carbon production line and delivers it through the smoke delivery pipe into the distribution chamber of the cloth cigarette box. This gradually increases the flue gas pressure within the distribution chamber. When the thrust exerted by the flue gas pressure on the cloth cigarette box exceeds the combined force of gravity and magnetic attraction, the cloth cigarette box moves upward along the smoke delivery pipe, causing its bottom to connect with the lower sealing plate. The process involves separating the smoke from the cooling water in the lower part of the collection chamber of the collection box, thereby opening multiple vents in the smoke box. This allows the smoke to be evenly distributed through the vents into the cooling water. The smoke forms tiny bubbles that float to the surface of the cooling water. During this process, the smoke in the distribution chamber of the smoke box exchanges heat with the cooling water through the outer wall of the smoke box, thus cooling it down. The smoke bubbles come into full contact with the cooling water, resulting in a cooling effect. Compared to existing technologies that use two cooling cycles, this process extends the cooling path and time of the smoke, improves the cooling effect, and enhances the adsorption of water-soluble impurities.

[0006] Preferably, it also includes a partition plate, which is installed on the upper port of the smoke supply pipe and located inside the distribution chamber of the cigarette pack. The partition plate divides the distribution chamber of the cigarette pack into upper and lower parts, so that after the smoke is discharged from the upper port of the smoke supply pipe, it first flows on the upper part of the partition plate, then enters the lower part of the partition plate and is discharged through multiple air outlets of the cigarette pack. This doubles the movement path of the smoke in the distribution chamber of the cigarette pack and improves the cooling effect.

[0007] Preferably, it also includes a one-way valve, which is installed on the upper port of the smoke supply pipe; by installing the one-way valve, the smoke in the distribution chamber of the smoke box is prevented from flowing back through the smoke supply pipe, and the cooling water is also prevented from flowing back through the smoke supply pipe, thereby improving the reliability of the smoke extractor.

[0008] Preferably, the system also includes a water tank, a water pump, a spray pipe, and a drain pipe. The water tank is mounted on a frame and has a water storage chamber inside. The water pump's suction pipe is located in the water storage chamber of the water tank. The input end of the spray pipe is connected to the water pump's outlet, and the output end of the spray pipe extends into the middle of the collection chamber of the collection tank. Multiple spray nozzles are installed at the output end of the spray pipe, and these nozzles are located above the cigarette pack. The drain pipe is installed on the outer wall of the collection tank, and its input end extends into the bottom of the collection chamber of the collection tank. The water storage chamber of the water tank stores cooling water. When the water pump operates, it draws out the cooling water and inputs it into the middle of the collection chamber of the collection tank through the spray pipe. The water sprays downward through the multiple spray nozzles, and the water mist gathers in the collection chamber of the collection tank to form a cooling water layer that submerges the cigarette pack. The water mist above the cooling water layer further cools and de-cools the smoke bubbles that float to the surface of the cooling water layer and adsorbs soluble impurities. The cooling water in the collection chamber of the collection tank is discharged through the drain pipe to maintain the depth of the cooling water layer.

[0009] Preferably, the system also includes a filter cartridge, a lid, and a filter cloth. The filter cartridge is installed on the upper surface of the collection box and is connected to the top of the collection chamber of the collection box. The lid is detachably installed on the upper port of the filter cartridge, and the filter cloth is detachably installed in the lower port of the filter cartridge. An exhaust pipe is provided on the side wall of the filter cartridge, and the exhaust pipe is located above the filter cloth. The filter cloth is installed on the lower port of the filter cartridge and filters the cooled flue gas, so that the dust in the flue gas is intercepted and adsorbed on the outer surface of the filter cloth. After being filtered and purified, the flue gas enters the filter cartridge and is discharged through the exhaust pipe, thereby achieving efficient dust collection.

[0010] Preferably, it also includes a push rod, a surrounding plate, elastic hooks, a dust collection hopper, a hook plate, and a shaped groove. The upper end of the push rod is slidably inserted into the middle of the bucket lid, and the upper end of the push rod extends above the bucket lid. The lower part of the push rod passes through the bottom center of the filter cloth, and the push rod is fixedly connected to the filter cloth. The lower end of the push rod is located below the filter cloth. The upper end face of the surrounding plate is connected to the top wall of the collection chamber of the collection box. The surrounding plate and the filter cloth are arranged concentrically. Elastic hooks are provided on the outer wall of the surrounding plate. The dust collection hopper is slidably fitted onto the outer wall of the surrounding plate. A smoke inlet is provided at the upper part of the dust collection hopper, and the upper edge of the dust collection hopper is provided with a groove that matches the elastic hook. The dust collection hopper is located below the filter cloth, and a hook plate is installed on the upper bottom surface of the hopper. A horizontal plate is installed on the hook plate, and a shaped groove is provided at the lower end of the push rod to match the hook plate. This groove includes an annular groove around the outer wall of the push rod for engaging the horizontal plate of the hook plate and a vertical groove for avoiding the horizontal plate of the hook plate; the annular groove and the vertical groove are connected. During operation, the upper edge of the dust collection hopper connects to the lower edge of the surrounding plate, opening the inlet of the dust collection hopper. The flue gas in the collection chamber of the collection box enters between the dust collection hopper and the filter cloth through the inlet, where the dust is filtered and intercepted by the filter cloth. The dust falls into the dust collection hopper. When the filter cloth needs to be replaced, lower the push rod so that the horizontal plate of the hook plate moves along the vertical groove of the irregular groove to the annular groove. Rotate the push rod so that the horizontal plate of the hook plate engages in the annular groove of the irregular groove, temporarily connecting the push rod to the dust collection hopper. Raise the push rod upward, pushing the dust collection hopper upward, so that the elastic hook hooks into the groove of the dust collection hopper. At this time, the flue gas inlet of the dust collection hopper is sealed by the surrounding plate, preventing flue gas from entering between the dust collection hopper and the filter cloth, thus avoiding the spread of flue gas and pollution of the atmosphere when replacing the filter cloth. Reverse the push rod so that the horizontal plate of the hook plate re-enters the irregular groove. In the vertical groove of the hopper, the push rod is disengaged from the dust collection hopper. The lid is opened, and the push rod is pulled out of the filter cartridge, allowing the push rod to remove the filter cloth from the filter cartridge. After replacing or cleaning the filter cloth, the lid is put back on the filter cartridge, and the push rod and filter cloth are put back into the filter cartridge. The push rod is pushed downwards, so that it presses against the bottom of the dust collection hopper and pushes the dust collection hopper downwards. When the pressure received by the dust collection hopper is greater than the hooking force of the elastic hook, the elastic hook disengages from the groove of the dust collection hopper, causing the dust collection hopper to descend and reset, and the smoke inlet of the dust collection hopper to reopen, completing the replacement of the filter cloth. It is highly practical.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: Cooling water is added to the collection chamber of the collection box, submerging the smoke box. When dust collection is not in progress, the weight of the smoke box is greater than its buoyancy, causing it to descend along the smoke delivery pipe. The bottom of the smoke box is then magnetically attached to the lower sealing plate. The sealing effect of the two sealing rings closes the multiple air vents of the smoke box. During operation, the exhaust fan draws in the flue gas generated by the carbon production line and inputs it into the distribution chamber of the smoke box through the smoke delivery pipe. This causes the flue gas pressure in the distribution chamber to gradually increase, and the thrust exerted by the flue gas pressure on the smoke box is greater than the force received by the smoke box. Under the influence of gravity and magnetic attraction, the cigarette pack moves upward along the cigarette delivery pipe, causing the bottom of the cigarette pack to detach from the lower sealing plate. This opens multiple vents in the cigarette pack, allowing the smoke to be evenly distributed into the cooling water at the bottom of the collection chamber of the collection box. The smoke forms tiny bubbles that float to the surface from the cooling water. During this process, the smoke in the distribution chamber of the cigarette pack is cooled by heat exchange with the cooling water through the outer wall of the cigarette pack. The smoke bubbles are fully in contact with the cooling water, resulting in cooling. Compared to existing technologies that use two cooling cycles, this method extends the cooling path and time of the smoke, improves the cooling effect, and enhances the adsorption of water-soluble impurities.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0020] Example 1

[0021] like Figures 1 to 5 As shown, a dust collection device for a carbon production line includes a frame 1, a fume extractor 2, and a collection box 3. The fume extractor 2 and the collection box 3 are mounted on the frame 1, with the fume extractor 2 located below the collection box 3. The collection box 3 has a collection chamber inside. It also includes a smoke delivery pipe 4, a smoke distribution box 5, a lower sealing plate 6, and two sealing rings 7. The lower end of the smoke delivery pipe 4 is connected to the smoke outlet of the fume extractor 2, and the upper end of the smoke delivery pipe 4 extends into the lower part of the collection chamber of the collection box 3. The smoke distribution box 5 has a distribution chamber inside, an insertion hole in the center of its bottom, and multiple air outlets at its bottom. The upper end of the smoke delivery pipe 4 is movably inserted into the smoke distribution box 5. In the insertion hole, a wear-resistant sealing ring is provided between the outer wall of the cigarette delivery pipe 4 and the insertion hole of the cigarette box 5. The upper port of the cigarette delivery pipe 4 is located in the middle of the distribution chamber of the cigarette box 5. The lower sealing plate 6 is fitted on the outer wall of the cigarette delivery pipe 4 and is located below the cigarette box 5. Two matching sealing rings 7 are provided on the upper end edge of the lower sealing plate 6 and the lower end edge of the cigarette box 5. Matching magnetic blocks are provided on the bottom of the lower sealing plate 6 and the cigarette box 5. It also includes a partition 8, which is installed on the upper port of the cigarette delivery pipe 4 and is located inside the distribution chamber of the cigarette box 5. It also includes a one-way valve 9, which is installed on the upper port of the cigarette delivery pipe 4.

[0022] Cooling water is added to the collection chamber of collection box 3, submerging the smoke box 5. When dust collection is not in progress, the weight of the smoke box 5 is greater than its buoyancy, causing it to descend along the smoke delivery pipe 4. The bottom of the smoke box 5 is then magnetically attached to the lower sealing plate 6. The two sealing rings 7 seal the multiple vents of the smoke box 5. During operation, the smoke extractor 2 draws in the flue gas generated by the carbon production line and inputs it into the distribution chamber of the smoke box 5 through the smoke delivery pipe 4. This gradually increases the flue gas pressure in the distribution chamber. When the thrust exerted by the flue gas pressure on the smoke box 5 exceeds the weight and magnetic force, the smoke box 5 moves upward along the smoke delivery pipe 4, causing its bottom to detach from the lower sealing plate 6. This opens the multiple vents of the smoke box 5, and the partition 8 separates the smoke box from the lower sealing plate 6. The distribution chamber of the smoke box 5 is divided into upper and lower parts, so that after the flue gas is discharged from the upper end of the smoke supply pipe 4, it first flows above the partition 8, and then enters the lower part of the partition 8. After entering the lower part of the partition 8, it is evenly distributed into the cooling water in the lower part of the collection chamber of the collection box 3 through multiple air outlets of the smoke box 5. This allows the flue gas to form small bubbles through the multiple air outlets of the smoke box 5 and float out of the cooling water. During this process, the flue gas in the distribution chamber of the smoke box 5 is cooled down by heat exchange with the cooling water through the outer wall of the smoke box 5. The flue gas bubbles are fully in contact with the cooling water for cooling. By installing a one-way valve 9, the flue gas in the distribution chamber of the smoke box 5 is prevented from flowing back through the smoke supply pipe 4, and the cooling water is also prevented from flowing back through the smoke supply pipe 4, which improves the reliability of the smoke extractor 2. Compared with the existing technology that uses two cooling stages, this technology extends the flue gas cooling path and time, and improves the cooling effect.

[0023] Example 2

[0024] like Figures 1 to 3 As shown, based on Embodiment 1, it also includes a water tank 10, a water pump 11, a spray pipe 12, and a drain pipe 13. The water tank 10 is installed on the frame 1, and a water storage chamber is provided inside the water tank 10. The water pump 11's pump pipe is located in the water storage chamber of the water tank 10. The input end of the spray pipe 12 is connected to the outlet of the water pump 11, and the output end of the spray pipe 12 extends into the middle of the collection chamber of the collection box 3. Multiple spray heads are installed at the output end of the spray pipe 12, and the multiple spray heads are located above the cloth cigarette box 5. The drain pipe 13 is installed on the outer wall of the collection box 3, and the input end of the drain pipe 13 extends into the bottom of the collection chamber of the collection box 3.

[0025] Cooling water is stored in the water storage chamber of water tank 10. After the water pump 11 operates, the cooling water is drawn out and input into the middle of the collection chamber of collection box 3 through water spray pipe 12. It is sprayed downward through multiple spray nozzles. The water mist gathers in the collection chamber of collection box 3 to form a cooling water layer that submerges the smoke box 5. The water mist above the cooling water layer further cools and lowers the smoke bubbles that float to the surface of the cooling water layer and adsorbs soluble impurities. The cooling water in the collection chamber of collection box 3 is discharged through drain pipe 13 to maintain the depth of the cooling water layer.

[0026] Example 3

[0027] like Figure 1 , Figure 2 and Figure 6 As shown, based on Embodiment 1, it also includes a filter cartridge 14, a lid 15, and a filter cloth 16. The filter cartridge 14 is installed on the upper end face of the collection box 3, and the filter cartridge 14 is connected to the top of the collection chamber of the collection box 3. The lid 15 is detachably installed on the upper port of the filter cartridge 14, and the filter cloth 16 is detachably installed in the lower port of the filter cartridge 14. An exhaust pipe is provided on the side wall of the filter cartridge 14, and the exhaust pipe is located above the filter cloth 16. It also includes a push rod 17, a surrounding plate 18, an elastic hook 19, a dust collection hopper 20, a hook plate 21, and a shaped groove 22. The upper end of the push rod 17 is slidably inserted into the middle of the lid 15, and the upper end of the push rod 17 extends above the lid 15. The lower part of the push rod 17 passes through the bottom center of the filter cloth 16, and the push rod 17 is fixedly connected to the filter cloth 16. The lower end of the push rod 17 is located at... Below the filter cloth 16, the upper end face of the surrounding plate 18 is connected to the top wall of the collection chamber of the collection box 3. The surrounding plate 18 and the filter cloth 16 are arranged concentrically. An elastic hook 19 is provided on the outer wall of the surrounding plate 18. The dust collection hopper 20 is slidably fitted on the outer wall of the surrounding plate 18. The upper part of the dust collection hopper 20 is provided with a smoke inlet. The upper edge of the dust collection hopper 20 is provided with a groove that matches the elastic hook 19. The dust collection hopper 20 is located below the filter cloth 16. A hook plate 21 is installed on the bottom upper surface of the dust collection hopper 20. A horizontal horizontal plate is provided on the hook plate 21. The lower end of the push rod 17 is provided with a special-shaped groove 22 that matches the hook plate 21. The special-shaped groove 22 includes an annular groove around the outer wall of the push rod 17 for engaging the horizontal plate of the hook plate 21 and a vertical groove for avoiding the horizontal plate of the hook plate 21. The annular groove and the vertical groove are connected.

[0028] The filter cloth 16 is installed on the lower end of the filter cartridge 14. The filter cloth 16 filters the cooled flue gas, causing the dust in the flue gas to be intercepted and adsorbed on the outer surface of the filter cloth 16. After being filtered and purified, the flue gas enters the filter cartridge 14 and is discharged through the exhaust pipe, achieving efficient dust collection. During operation, the upper edge of the dust collection hopper 20 is connected to the lower edge of the enclosure plate 18, so that the flue gas inlet of the dust collection hopper 20 is opened, and the flue gas in the collection chamber of the collection box 3 enters the dust collection hopper 20 through the flue gas inlet. Between the dust hopper 20 and the filter cloth 16, the dust filtered and intercepted by the filter cloth 16 falls into the dust hopper 20 for collection. When the filter cloth 16 needs to be replaced, the push rod 17 is lowered, so that the horizontal plate of the hook plate 21 reaches the annular groove along the vertical groove of the irregular groove 22. The push rod 17 is rotated, so that the horizontal plate of the hook plate 21 is engaged in the annular groove of the irregular groove 22, so that the push rod 17 is temporarily connected to the dust hopper 20. The push rod 17 is then raised, pushing the dust hopper 20 upward, so that the elastic hook 19 holds the dust hopper. The groove of dust collection hopper 20 is hooked, and the inlet of dust collection hopper 20 is sealed by the enclosure plate 18, preventing flue gas from entering between dust collection hopper 20 and filter cloth 16, thus avoiding the spread of flue gas and pollution of the atmosphere when replacing filter cloth 16. Reverse push rod 17, so that the horizontal plate of hook plate 21 enters the vertical groove of irregular groove 22 again, so that push rod 17 is disengaged from dust collection hopper 20. Open the bucket cover 15, and pull push rod 17 out of filter cylinder 14, so that push rod 17 drives filter cloth 16 out of filter cylinder 14 for replacement or cleaning. After removing the filter cloth 16, put the lid 15 back onto the filter cartridge 14, and put the push rod 17 and filter cloth 16 back into the filter cartridge 14. Push the push rod 17 downwards so that it presses against the bottom of the dust collection hopper 20 and pushes the dust collection hopper 20 downwards. When the pressure received by the dust collection hopper 20 is greater than the hooking force of the elastic hook 19, the elastic hook 19 disengages from the groove of the dust collection hopper 20, causing the dust collection hopper 20 to descend and reset, thus reopening the smoke inlet of the dust collection hopper 20 and completing the replacement of the filter cloth 16. This method is highly practical.

[0029] For example Figures 1 to 6As shown, this utility model discloses a dust collection device for a carbon production line. During operation, cooling water is first stored in the water storage chamber of the water tank 10. The water pump 11 draws out the cooling water and inputs it into the middle of the collection chamber of the collection box 3 through the spray pipe 12. Multiple spray nozzles then spray the water downwards, causing the water mist to accumulate in the collection chamber of the collection box 3, forming a cooling water layer that submerges the smoke box 5. When dust collection is not in progress, the weight of the smoke box 5 is greater than its buoyancy, causing it to descend along the smoke delivery pipe 4. The bottom of the smoke box 5 is then magnetically attached to the lower sealing plate 6. The sealing effect of the two sealing rings 7 seals the multiple air vents of the smoke box 5. During operation, the smoke extractor 2 draws in the flue gas generated by the carbon production line and inputs it into the distribution chamber of the smoke box 5 through the smoke delivery pipe 4. This causes the flue gas pressure in the distribution chamber of the smoke box 5 to gradually increase. The thrust exerted by the flue gas pressure on the smoke box 5 is greater than the weight and magnetic attraction of the smoke box 5. When the force is applied, the smoke box 5 moves upward along the smoke delivery pipe 4, causing the bottom of the smoke box 5 to separate from the lower sealing plate 6, thereby opening the multiple air outlets of the smoke box 5. This allows the smoke to flow along the partition plate 8 and then be evenly distributed into the cooling water at the bottom of the collection chamber of the collection box 3 through the multiple air outlets of the smoke box 5. The smoke forms tiny bubbles that float out of the cooling water. During this process, the smoke in the distribution chamber of the smoke box 5 is cooled down by heat exchange with the cooling water through the outer wall of the smoke box 5. The smoke bubbles are fully contacted with the cooling water for cooling down. The water mist above the cooling water layer further cools down the smoke bubbles that float out of the cooling water layer and adsorbs soluble impurities. The cooling water in the collection chamber of the collection box 3 is discharged through the drain pipe 13 to maintain the depth of the cooling water layer. Finally, the filter cloth 16 filters the cooled smoke, so that the dust in the smoke is intercepted and adsorbed on the outer surface of the filter cloth 16. The filtered and purified smoke enters the filter cartridge 14 and is discharged through the exhaust pipe.

[0030] The main functions achieved by this utility model are:

[0031] 1. The two-stage cooling process extends the cooling path and time of the flue gas, improving the cooling effect and the adsorption effect of impurities.

[0032] 2. Spray cooling is used to improve the cooling effect of dust.

[0033] 3. Convenient and quick filter cloth replacement 16.
