Description

Technical Field

[0001] The present invention relates to the technical field of soot removal mechanisms, and specifically to a soot removal mechanism for preventing air pollution in the processing of bio-based asphalt. Background Art

[0002] The air pollution generated during the production of asphalt mainly comes from the heating and combustion processes of asphalt. Under high-temperature conditions, asphalt releases substances harmful to the natural environment and human health. Therefore, the soot removal mechanism is mainly used to control and reduce the soot and harmful substances generated during the asphalt processing, ensuring environmental and operational safety. The soot removal mechanism in the bio-based asphalt processing and mixing device is an important link in achieving sustainable development. Through effective technical means, it can significantly reduce environmental pollution and operational risks.

[0003] The patent with the publication number CN214389438U discloses a soot removal mechanism for a bio-based asphalt processing and mixing device, including a heating cylinder and a coarse filter cylinder. The upper part of the coarse filter cylinder is communicated with a fine filter cylinder. The fine filter cylinder is sequentially provided with a negative electrode net, a positive electrode net, and a fan from the inlet to the outlet. And a booster is fixedly connected to the outer wall of the fine filter cylinder. The booster is electrically connected to both the positive electrode net and the negative electrode net. A nozzle is arranged above one side of the positive electrode net. In this patent, the flue gas first passes through the negative electrode net. The current is boosted by the booster, forming a strong electric field in the negative electrode net, so that the passing fine particles are charged negatively. The air mixed with fine particles continues to move forward along the air flow channel, encounters the positive electrode net, and is adsorbed by the positive electrode net. The water flow sprayed from the nozzle acts on the positive electrode net, flushing the impurities on the positive electrode net into the drain pipe, and then flowing into the water tank for subsequent circulation, saving resources.

[0004] However, during the use of the above device, dust will accumulate at the filter, which will affect its ventilation and subsequent dust filtration effect. Therefore, a soot removal mechanism for preventing air pollution in the processing of bio-based asphalt is proposed to solve the above problems. Summary of the Invention

The rotating column one 701 is fixedly connected to the output end of the motor 6, the filtering circular plate 702 is fixedly connected to the circumferential surface of the rotating column one 701, the triangular scraping plate 703 is fixedly connected to the inner wall of the primary filter cylinder 1, the pressing block 704 is fixedly connected to the surface of the filtering circular plate 702, the telescopic spring rod one 706 is fixedly connected to the inner wall of the primary filter cylinder 1, the pushing block 705 is fixedly connected to the side of the telescopic spring rod one 706 close to the rotating column one 701. When the device is started, the soot enters the primary filter cylinder 1 through the air inlet pipe two 14, and the motor 6 is started at the same time. The output end of the motor 6 drives the rotating column one 701 to start rotating. The rotating column one 701 drives the filtering circular plate 702 to rotate, so that a part of the soot particles stay on the surface of the filtering circular plate 702 under the rotation of the filtering circular plate 702, reducing a part of the particles and dust in the soot. Under the rotation of the filtering circular plate 702, the pressing block 704 is driven to rotate. When the pressing block 704 rotates, it will come into contact with and press the pushing block 705. The pressing of the pressing block 704 and the pushing block 705 will cause a certain vibration of the filtering circular plate 702, and the adhered dust and harmful particles on the surface of the filtering circular plate 702 will be vibrated and fall to the bottom of the primary filter cylinder 1, facilitating the later cleaning and collection of the dust and harmful particles in the soot, and improving the use efficiency of the device.

It makes the air inside the primary filter cylinder 1 move, and guides the soot gas in the primary filter cylinder 1 into the first intake pipe 5 through the fan blade 709, improving the smoothness of the device and accelerating the cleaning of impurities and particles in the soot gas.

[0016] Working principle: When the device is started, the soot in the asphalt processing enters the primary filter cylinder 1 through the second intake pipe 14. The motor 6 is started simultaneously. The output end of the motor 6 drives the rotating column I 701 to start rotating. The rotating column I 701 drives the filter circular plate 702 to rotate, so that some of the soot particles stay on the surface of the filter circular plate 702 under the rotation of the filter circular plate 702, reducing some of the particles and dust in the soot. Under the rotation of the filter circular plate 702, the extrusion block 704 is driven to rotate. The rotation of the extrusion block 704 will come into contact with and squeeze the pushing block 705. The extrusion between the extrusion block 704 and the pushing block 705 will cause the filter circular plate 702 to vibrate to a certain extent, and the adhered dust and harmful particles on the surface of the filter circular plate 702 will be vibrated and fall to the bottom of the primary filter cylinder 1, facilitating the later cleaning and collection of the dust and harmful particles in the soot, improving the use efficiency of the device, and preventing the filter from being blocked. When the soot enters the primary filter cylinder 1, the rotating column II 708 will rotate. The rotating column II 708 drives the fan blade 709 to rotate. The rotating column II 708 also drives the sleeve block 710 to rotate. The rotation of the sleeve block 710 drives the scraping rod 711 to rotate. The rotation of the scraping rod 711 drives the arc-shaped plate 712 to rotate. The arc-shaped plate 712 continuously scrapes the inner wall of the fan cylinder 707, preventing impurities and particles from blocking the fan cylinder 707 and weakening the fan effect. It makes the air inside the primary filter cylinder 1 move, and guides the soot gas in the primary filter cylinder 1 into the first intake pipe 5 through the fan blade 709, improving the smoothness of the device and accelerating the cleaning of impurities and particles in the soot gas.

[0017] Please refer to Figures 1 - 8, on the basis of the above embodiments, in another embodiment of the present invention, the stirring mechanism 8 includes a rotating column three 801, a connecting circular block 802, stirring blades 803, a stirring rod 804, a disc 813, and a telescopic elastic rod two 815. The telescopic elastic rod two 815 is fixedly connected to the inner bottom of the fine filter cylinder 3. The disc 813 is rotatably connected to the surface of the telescopic elastic rod two 815. The rotating column three 801 is rotatably connected to the inner wall of the fine filter cylinder 3. The connecting circular block 802 is fixedly connected to the circumferential surface of the rotating column three 801. The stirring blades 803 are fixedly connected to the circumferential surface of the connecting circular block 802. The stirring rod 804 is fixedly connected to the surface of the stirring blades 803. When the flue gas enters the fine filter cylinder 3 through the first intake pipe 5, the first intake pipe 5 will discharge the flue gas into the inner bottom area of the fine filter cylinder 3. The water pump 10 will mix water and chemical agents and enter them into the water inlet column 805. The mixed liquid will be discharged into the fine filter cylinder 3 through the circular nozzle 809, causing harmful substances such as sulfur dioxide in the flue gas to react. At the same time, the output end of the device will drive the rotation of the rotating column three 801. The rotating column three 801 drives the connecting circular block 802 to rotate. The connecting circular block 802 drives the stirring blades 803 to rotate. The stirring blades 803 drive the stirring rod 804 to rotate, continuously stirring the liquid, enabling the chemical liquid to fully blend and contact with the particulate matter in the flue gas, causing the impurities in the flue gas to precipitate and fuse, further improving the treatment effect of the flue gas and reducing environmental pollution caused by emissions. The stirring mechanism 8 further includes a water inlet column 805, a blocking cover 806, a pressing arc plate 807, a connecting plate 808, a circular nozzle 809, a supporting cylinder 810, a bottom cover 811, a downward pushing column 812, and a connecting groove block 814. The water inlet column 805 is connected through the inner wall of the fine cylinder cover 12. The blocking cover 806 is slidably connected to the circumferential surface of the water inlet column 805. The pressing arc plate 807 is fixedly connected to the circumferential surface of the blocking cover 806.

The water inlet column 805 is fixedly connected to the output end of the water pump 10. When the liquid reaches a certain amount, its gravity will squeeze the telescopic elastic rod two 815, causing the disc 813 to move downward. The movement of the disc 813 will expose the diversion pipe 4. The diversion pipe 4 enables the liquid and sediment to flow through the pipeline to the surface of the filter circular plate 702, further flushing the dust and particulate matter on the surface of the filter circular plate 702. At the same time, the downward movement of the disc 813 will drive the downward movement of the downward pushing column 812. The downward pushing column 812 drives the connecting plate 808 to move. The connecting plate 808 drives the pressing arc plate 807 to move. The pressing arc plate 807 drives the blocking cover 806 to move downward and cover the circular nozzle 809, preventing new mixed liquid from continuing to be discharged during the discharge of the liquid, reducing the waste of chemical liquid and the usage cost.

[0018] The cleaning mechanism 9 includes a fitting block 901, a fixing column 902, a long strip block 903, a cleaning arc plate 904, and an L-shaped block 909.

When the disc 813 moves downward, the fitting block 901 will move downward and fit with the connecting groove block 814, so that the connecting groove block 814 rotates to drive the disc 813 to rotate. The disc 813 rotates to drive the fixing column 902 to move, the fixing column 902 drives the long strip block 903 to move, and the long strip block 903 drives the cleaning arc plate 904 to move and rotate following the disc 813, so that the cleaning arc plate 904 scrapes off the reaction precipitates caused by the chemical liquid and the soot. The precipitates adhered to the inner wall of the fine filter cylinder 3 will flow out through the diversion pipe 4 along with the liquid, increasing the service life of the device, preventing the precipitates from adhering to the inner wall of the fine filter cylinder 3, and thus affecting the subsequent soot removal effect. The L-shaped block 909 is fixedly connected to the inner wall of the fixing column 902. The cleaning mechanism 9 further includes a roller 905, an inner connecting column 906, a collecting plate 907, and a baffle 908.

The baffle 908 is fixedly connected to the left and right sides of the collecting plate 907. The cleaning arc plate 904 is fixedly connected to the side of the L-shaped block 909 away from the fixing column 902. The roller 905 contacts the inner surface of the fine filter cylinder 3, and the cleaning arc plate 904 contacts the inner wall of the fine filter cylinder 3. At the same time, the movement of the fixing column 902 drives the inner connecting column 906 to move, the inner connecting column 906 drives the collecting plate 907 to move, and the collecting plate 907 drives the roller 905 to move. Since the roller 905 contacts the inner wall of the fine filter cylinder 3, the roller 905 will rotate and drive the collecting plate 907 to rotate, so that when the cleaning arc plate 904 scrapes, the collecting plate 907 can rotate and collect the precipitates on its own surface, improving the subsequent collection efficiency of the precipitates and the internal cleaning effect of the fine filter cylinder 3.

[0019] Working principle: When the fume gas enters the fine filter cartridge 3 through the first inlet pipe 5, the first inlet pipe 5 will discharge the fume gas in the inner bottom area of the fine filter cartridge 3. The water pump 10 will mix water and chemical agents and enter the water inlet column 805. After mixing, the liquid will pass through the circular nozzle 809 and be discharged into the fine filter cartridge 3, causing harmful substances such as sulfur dioxide in the fume to react. At the same time, the output end of the motor will drive the third rotating column 801 to rotate. The third rotating column 801 drives the connecting circular block 802 to rotate, the connecting circular block 802 drives the stirring blade 803 to rotate, and the stirring blade 803 drives the stirring rod 804 to rotate, continuously stirring the liquid, enabling the chemical liquid to fully blend and contact with the particulate matter in the fume, causing the impurities in the fume to precipitate and blend, further improving the treatment effect of the fume, reducing environmental pollution caused by emissions. When the liquid reaches a certain amount, its gravity will squeeze the second telescopic spring rod 815, causing the disc 813 to move downward. The movement of the disc 813 will expose the diversion pipe 4. The diversion pipe 4 enables the liquid and sediment to flow through the pipeline to the surface of the filter circular plate 702, further flushing the dust and particulate matter on the surface of the filter circular plate 702. At the same time, the downward movement of the disc 813 will drive the downward push column 812 to move, the downward push column 812 drives the connecting plate 808 to move, the connecting plate 808 drives the pressing arc plate 807 to move, and the pressing arc plate 807 drives the blocking cover 806 to move downward and cover the circular nozzle 809, preventing new mixed liquid from continuing to be discharged during the liquid discharge, reducing the waste of chemical liquid and the usage cost.

[0020] When the disc 813 moves downward, the mating block 901 will move downward and mate with the connecting groove block 814. Thus, the rotation of the connecting groove block 814 drives the disc 813 to rotate. The rotation of the disc 813 drives the fixed column 902 to move. The fixed column 902 will drive the long strip block 903 to move. The long strip block 903 drives the cleaning arc plate 904 to move and rotate following the disc 813, enabling the cleaning arc plate 904 to scrape off the reaction precipitates due to the chemical liquid and the fume. The precipitates adhered to the inner wall of the fine filter cartridge 3 will flow out through the diversion pipe 4 along with the liquid, increasing the service life of the device, preventing the precipitates from adhering to the inner wall of the fine filter cartridge 3 and affecting the subsequent fume removal effect. At the same time, the movement of the fixed column 902 will drive the inner connecting column 906 to move. The inner connecting column 906 drives the collecting plate 907 to move. The collecting plate 907 drives the roller 905 to move. Since the roller 905 contacts the inner wall of the fine filter cartridge 3, the roller 905 will rotate and drive the collecting plate 907 to rotate, enabling the collecting plate 907 to rotate when the cleaning arc plate 904 scrapes, and collecting the precipitates on its own surface, improving the subsequent collection efficiency of the precipitates and the internal cleaning effect of the fine filter cartridge 3.
