Description

Technical Field

[0001] The invention relates to the technical field of gas treatment for cold asphalt regeneration paving, and in particular to a gas treatment device for cold asphalt regeneration paving of road surface. Background Art

[0002] Through the cold recycling technology of asphalt pavement, the old asphalt pavement can be processed and re-paved on the road for reuse. This not only allows the old asphalt pavement to be reused, but also saves resources. Since some volatile organic compounds may be released from the asphalt material during the paving process, a gas treatment device is required during the paving process of asphalt pavement.

[0003] The patent name disclosed in the application number "CN202123365903.4" in the prior art is "A smoke collection and treatment device for an asphalt pavement paver". When in use, there is a trapezoidal air suction port under the induced draft hood, and a number of wind tunnels are opened at the bottom. The tops of the two induced draft hoods are connected to each other through pipes, and the tops of the induced draft hoods are connected to the collecting chamber inside the installation box through pipes. Then the collecting chamber of the columnar container temporarily stores the smoke and plays a certain buffering role. The molecular sieve performs preliminary filtration on the smoke, and the high-temperature asphalt smoke treated by the collecting chamber flows into the condenser. When the high-temperature asphalt smoke flows through the condenser, the gas temperature decreases and the molecular movement rate slows down, which is conducive to the full adsorption of harmful substances in the subsequent gas. Then the smoke enters the filter chamber, and the adsorption plates are arranged in an "S" shape in the filter chamber, which can ensure that the harmful substances in the asphalt smoke can be adsorbed to the greatest extent when the asphalt smoke enters the filter chamber. At this time, the smoke enters the fuel chamber through the connected pipe, and is finally discharged into the atmosphere through the exhaust channel;

[0004] The patent name disclosed in the application number "CN202010274626.7" in the prior art is "A toxic gas treatment device for asphalt paving equipment". Toxic gas will be stored between two adjacent blades of the rotating fan during rotation. During the continuous rotation of the rotating fan, the upper end of the shell is made of a good thermal conductor material, the upper end of the shell is in a low temperature state, and the lower part of the shell is in a high temperature state. The high-pressure gas in the high-temperature environment rises, and the low-pressure gas in the low-temperature environment falls, then an airflow will be formed. After the gas in the circulation cavity rises, it passes through the upper opening and the upper end of the shell and falls from the outside of the shell. The toxic gas continues to rise, and a filter layer is provided in the upper part of the circulation cavity. The filter layer can effectively absorb harmful substances in the rising toxic gas, and the pores in the structure of the activated carbon are used to effectively absorb the toxic gas, so that the gas finally discharged from the upper end of the shell is treated gas, which creates a relatively safe working environment for the surrounding staff and protects the safety of the staff. Moreover, since the device directs the toxic gas emitted by the asphalt to flow, the directional airflow can effectively prevent the gas from scattering in the air and affecting the environment.

[0005] The position and size of the flow chamber of the gas treatment device are fixed when in use, so the area of ​​the gas treatment device to treat the gas generated during the cold regeneration and paving of the road asphalt is limited. It takes a long time to treat the gas generated during the cold regeneration and paving of the road asphalt over a large area, resulting in a low treatment efficiency.

[0006] Therefore, we propose a gas treatment device for cold recycling and paving of road asphalt in order to solve the above-mentioned problems. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] See also Figure 1-Figure 10 , the present invention provides the following technical solutions:

[0053] Embodiment 1: The gas treatment device for cold regeneration and paving of asphalt pavement in this embodiment can increase the area of ​​gas treatment when in use, thereby improving the efficiency of gas treatment. Figure 1-Figure 7 And attached Fig. 9 As shown, it includes an outer shell 1 and a row of filter element bodies 9 installed in the outer shell 1; the front and rear side surfaces of the outer shell 1 are grooved and slidably installed with sliding components 2, and the bottom surface of the sliding component 2 is installed with a movable frame 3 in a "U" shape structure; the inner wall of the movable frame 3 is installed with multiple rows of rotatable air suction frames 12, and an air inlet pipe 121 is installed above the air suction frame 12; the bottom surface of the outer shell 1 is grooved and embedded with a connecting cloth 101; the top of the air inlet pipe 121 passes through the inside of the connecting cloth 101; a partition 17 is installed inside the outer shell 1, and the partition 17 is arranged above the filter element body 9, and the front end of the filter element body 9 passes through the front side of the outer shell 1 and is inserted into the air collecting frame 7 installed on the front side of the outer shell 1; a suction fan 8 is installed above the air collecting frame 7 through a pipeline, and the pipeline above the suction fan 8 is inserted into the outer shell 1; an activated carbon adsorption plate 16 is installed above the partition 17. The highest point of the moving frame 3 is lower than the lowest point of the outer shell 1. An electric push rod 4 is installed in the groove on the front side of the outer shell 1. The output end of the electric push rod 4 is connected to the sliding assembly 2 on the front side of the outer shell 1. The moving frame 3 forms a left-right sliding structure with the outer shell 1 through the sliding assembly 2. The upper right side of the suction frame 12 is connected to the moving frame 3 through the main rotating rod 10, and the upper left side of the suction frame 12 is connected to the moving frame 3 through the secondary rotating rod 21;

[0054] First, the mounting frame 6 is installed on the external road asphalt cold regeneration paver, and then the external road asphalt cold regeneration paver will drive the gas treatment device to move together during the asphalt paving process, and the suction fan 8 is started at this time. At this time, the gas generated during the road asphalt cold regeneration paving is sucked into the outer shell 1 through the multiple rows of suction frames 12 and the air inlet pipe 121 for filtering treatment, and at the same time, the electric push rod 4 in the front side groove of the outer shell 1 is started, and the output end of the electric push rod 4 drives the sliding assembly 2 to move back and forth, so that the sliding assembly 2 can slide stably in the grooves on the front and rear sides of the outer shell 1, and the sliding assembly 2 drives the lower "U"-shaped moving frame 3 to move back and forth, and the moving frame 3 drives the internal multiple rows of suction frames 12 to move back and forth, so that the suction frame 12 can suck gas from other areas, which can increase the suction treatment area of ​​the suction frame 12;

[0055] When the movable frame 3 drives the air suction frame 12 to move left or right, at this time, since the movable frame 3 moves and the outer shell 1 is fixed, one end of the rotation control rope 11 installed on the surface of the outer shell 1 will be pulled, so that the pulled rotation control rope 11 drives the main rotation rod 10 to rotate, and the main rotation rod 10 drives the air suction frame 12 to rotate. At this time, the vortex spring 20 accumulates force. When the movable frame 3 drives the air suction frame 12 to move in the opposite direction and reset, the main rotation rod 10 can be automatically driven to rotate in the opposite direction through the stored force of the vortex spring 20, thereby making the main rotation rod 10 drive the air suction frame 12 to rotate in the opposite direction and reset. Therefore, while the air suction frame 12 reciprocates left and right, it will also reciprocate at a certain angle with the main rotation rod 10 as the center of the circle. Therefore, the air suction position and air suction angle of the air suction frame 12 can be adjusted, thereby increasing the air suction area of ​​the gas treatment device, which is convenient for improving the efficiency of the gas treatment device for the later stage;

[0056] When the air intake frame 12 moves left and right or rotates, the air intake pipe 121 is driven to move left and right and rotate together. At this time, the connecting cloth 101 at the bottom of the outer shell 1 will be pulled. Therefore, through the setting of the connecting cloth 101, the position of the air intake pipe 121 can be adjusted at will, and the air intake pipe 121 will not be bent to affect the subsequent air intake operation.

[0057] Then the gas in the outer shell 1 is first filtered through a row of filter core bodies 9 that are fitted together, so that the filtered gas enters the interior of the filter core body 9, and the filtered gas enters the gas collecting frame 7 through the pipeline at the front end of the filter core body 9, and then the gas in the gas collecting frame 7 is transported to the outer shell 1 above the partition 17 through the suction fan 8, and then the harmful substances in the gas are adsorbed again by the activated carbon adsorption plate 16, and then the treated gas can be discharged through the exhaust port at the top of the outer shell 1;

[0058] Embodiment 2: The gas treatment device for cold regeneration and paving of asphalt pavement in this embodiment can first filter the gas to prevent more impurities from remaining in the air intake frame 12. Figure 5-Figure 8 As shown, on the basis of the first embodiment, the right end of the main rotating rod 10 penetrates the right side of the moving frame 3, the suction frame 12 rotates with the center of the main rotating rod 10 as the center, and a rotation control mechanism is installed on the right end of the main rotating rod 10. The rotation control mechanism includes a rotation control rope 11 wound and installed on the outside of the right end of the main rotating rod 10, the upper end of the rotation control rope 11 is connected to the right side of the outer shell 1 through a guide wheel, and the main rotating rod 10 forms a rotating structure through the rotation control rope 11; a vortex spring 20 is installed on the outside of the main rotating rod 10. Two adjacent filter core bodies 9 are arranged in close contact, and the filter core body 9 on the far left and the filter core body 9 on the far right are both arranged in close contact with the inner wall of the outer shell 1, and the front end of the filter core body 9 is arranged in close contact with the inner wall of the outer shell 1. The left and right sides of the outer shell 1 are both equipped with mounting frames 6, and the mounting frame 6 is connected to the external paver.

[0059] A filter screen 5 is installed below the moving frame 3, and a counterweight frame 14 in the shape of a "U" is installed on the inner wall of the bottom surface of the filter screen 5; the upper surfaces of the front and rear sides of the counterweight frame 14 are connected to the bottom surface of the moving frame 3 through spring telescopic rods 13, and the spring telescopic rods 13 are composed of a manual telescopic rod and a connecting spring, and a connecting spring is sleeved on the lower outer side of the manual telescopic rod. The main rotating rod 10 and the slave rotating rod 21 are both wound and connected with a pulling control rope 15, and the bottom end of the pulling control rope 15 is connected to the upper surfaces of the left and right sides of the counterweight frame 14, and the bottom surface of the counterweight frame 14 and the filter screen 5 can be moved upward by pulling the pulling control rope 15;

[0060] When the suction fan 8 is started, the gas generated during the cold regeneration and paving of the road asphalt is first filtered through the filter screen cover 5 and then enters the suction frame 12, and then the gas is transported to the outer shell 1 for processing through the cooperation of the suction frame 12 and the air inlet pipe 121. When the main rotating rod 10 drives the suction frame 12 to rotate, the suction frame 12 will drive the upper left slave rotating rod 21 to rotate together, so that the main rotating rod 10 and the slave rotating rod 21 rotate together to pull and reel the pulling control rope 15 installed on the outside. At this time, the pulling control rope 15 pulls the bottom surface of the counterweight frame 14 and the filter screen cover 5 upward. When the counterweight frame 14 is pulled, the spring telescopic rod 13 is squeezed when the counterweight frame 14 moves upward, so that the connecting spring on the outer side of the spring telescopic rod 13 accumulates force. When the main rotating rod 10 and the slave rotating rod 21 rotate in the opposite direction to reset, the pulling control rope 15 is released. Then, the bottom surface of the filter screen cover 5 is automatically driven downward by the gravity of the counterweight frame 14 and the accumulated force of the connecting spring on the outer side of the spring telescopic rod 13. This operation is repeated, so that the bottom surface of the filter screen cover 5 is reciprocatedly lifted and lowered, so that impurities on the surface of the filter screen cover 5 can be shaken off to avoid affecting the filtering use of the filter screen cover 5 in the later stage.

[0061] Embodiment 3: The gas treatment device for cold regeneration and paving of asphalt pavement in this embodiment can collect and discharge the impurities cleaned off the surface of the filter element body 9. Figure 9-10 As shown, the rear end of the filter element body 9 penetrates the rear side of the outer shell 1, and the rear end of the filter element body 9 is connected through a sprocket assembly; a cleaning brush mechanism 19 with an arc-shaped structure is provided above the front end of the filter element body 9, and the cleaning brush mechanism 19 is provided in a one-to-one correspondence with the filter element body 9;

[0062] A connecting plate 191 is installed above the cleaning brush mechanism 19, and a threaded rod 192 is threadedly connected inside the connecting plate 191. The cleaning brush mechanism 19 forms a front-to-back sliding structure with the filter element body 9 through the threaded rod 192. The front and rear ends of the threaded rod 192 are connected to the inner wall of the outer shell 1, and the rear end of the threaded rod 192 penetrates the rear side of the outer shell 1. A slag discharge port 102 is provided on the rear side of the outer shell 1, and a sealing plate is installed on the outside of the slag discharge port 102; a collecting frame 18 is installed inside the rear side of the outer shell 1, and a filter element body 9 is provided on the front side of the collecting frame 18. The rear end of the filter element body 9 penetrates the interior of the collecting frame 18, and the highest point of the collecting frame 18 is lower than the center height position of the filter element body 9; the space inside the slag discharge port 102 is connected to the space inside the collecting frame 18; the bottom surface of the collecting frame 18 is arranged in an inclined shape, and a through opening is provided below the rear side of the collecting frame 18, and the through opening coincides with the slag discharge port 102;

[0063] After the filter element body 9 has been used for a period of time, when it is necessary to process the impurities on the surface of the filter element body 9, the rear end of the threaded rod 192 is connected to an external servo motor, and then the servo motor drives the threaded rod 192 to rotate. At this time, the threaded rod 192 drives the connecting plate 191 connected to the outer thread to move backward when it rotates. At this time, the connecting plate 191 drives the multiple cleaning brush mechanisms 19 below to move backward. At this time, the cleaning brush mechanism 19 brushes some impurities on the upper surface of the filter element body 9 into the collection frame 18, and then the servo motor drives the threaded rod 192 to rotate in the opposite direction, so that the threaded rod 192 drives the cleaning brush mechanism 19 to move forward and reset, and then the rear end of one of the filter element bodies 9 is connected to an external motor, and the motor drives the filter element body 9 to rotate 60°. At this time, since the rear sides of a row of multiple filter element bodies 9 are connected by a sprocket assembly, one of the filter element bodies 9 can be driven when it rotates. The other filter element bodies 9 are driven to rotate and can be adjusted synchronously. Then, as shown above, the threaded rod 192 is rotated again to make the cleaning brush mechanism 19 move backward to scrape the impurities on the surface of the filter element body 9 and put them into the collection frame 18. In this way, the arc-shaped cleaning brush mechanism 19 can scrape the impurities at various positions on the outer side of the filter element body 9, so that the impurities can enter the collection frame 18 well. At a later time, the sealing plate outside the slag discharge port 102 is opened, so that the impurities in the collection frame 18 with an inclined bottom can enter the slag discharge port 102 and be discharged, so as to facilitate the collection of impurities cleaned off the surface of the filter element body 9. Since the multiple filter element bodies 9 are fitted together, and the leftmost filter element body 9 and the rightmost filter element body 9 are also fitted with the inner wall of the outer shell 1, impurities are prevented from falling into the outer shell 1, thereby completing a series of tasks.
