Description

Technical Field

[0001] The present invention relates to the technical field of asphalt processing, in particular to an exhaust gas absorption device for asphalt processing. Background Art

[0002] The exhaust gas generated during asphalt processing is usually discharged directly. The exhaust gas generated during asphalt processing contains harmful substances, which will pollute the surrounding environment and affect the physical and mental health of surrounding residents. In addition, the exhaust gas will produce particulate matter during the treatment and discharge. If it is not cleaned in time, it is easy to cause internal blockage of the emission device, thereby reducing the air permeability of the device and reducing the working efficiency of the device.

[0003] To this end, Chinese patent publication number "CN221906235U" discloses an "Asphalt Processing Exhaust Gas Exhaust Device." Its main structure includes a purification box with a condenser box installed on one side, which is interconnected with the condenser box. An intake pipe is installed on the side of the purification box away from the condenser box. The intake pipe is connected to the asphalt processing exhaust pipe, and the amount of exhaust gas entering the purification box is controlled by a control valve. After entering the purification box, the exhaust gas is first filtered by two filter plates, which adsorb nicotine particles in the asphalt exhaust gas onto the filter plates, thereby providing initial purification. The preliminarily purified exhaust gas then passes through a holding box with multiple through-holes on its outer surface to facilitate exhaust gas circulation. The interior of the holding box is filled with activated carbon, which absorbs harmful substances in the exhaust gas. The exhaust gas enters the condenser box, and multiple condensation rods are installed at the upper end of the condenser box, which is beneficial for purifying the asphalt exhaust gas in ultra-low temperature environments.

[0004] When the exhaust emission device is used to clean the particulate matter attached to and blocked in the filter screen plate, the following steps need to be performed: the two filter screen plates can be taken out from the inside of the card slot by using handle 1 for cleaning. The upper ends of the two filter screen plates are provided with sealing rings, which can better improve the sealing and prevent the exhaust gas from leaking from the card slot. Then the sealing cover is removed. T-shaped plates are installed on both sides of the sealing cover through rectangular blocks. The T-shaped plates are embedded in the inside of the T-shaped groove opened on the outer surface of the limit plate, which can play the role of sealing the rectangular groove. The placement box can be taken out from the inside of the rectangular groove by using handle 2 to replace the activated carbon. The electric telescopic rod is turned on to drive the cleaning plate to push the particulate matter remaining in the purification box and the condensation box to the rectangular groove, and then clean it out. The whole process is relatively cumbersome, and the entire activated carbon needs to be replaced, which makes the activated carbon a disposable item and cannot be recycled, and the environmental protection level is low.

[0027] See also Figure 1 and Figure 2 , an exhaust gas absorption device for asphalt processing. Before work, the annular structure of the docking channel structure 14 is connected to the exhaust port of an exhaust device through a bearing and a sealing ring, and then the device is moved to a confined space where the exhaust gas is discharged.

[0028] To achieve effective filtering of the flowing exhaust gas, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , it is necessary to set up a rotating exhaust gas filtering mechanism 1, which is provided with a polyhedron shell 11 that can rotate and is hollow inside, a filter screen 19 installed on the vertical surface of the polyhedron shell 11 through a bearing and capable of filtering the flowing exhaust gas, and a rubber driven ring 110 installed on the periphery of the filter screen 19 and capable of driving the filter screen 19 to rotate. When the exhaust equipment is turned on, the exhaust gas in the external environment will be filtered through the filter screen 19 and enter the filter cavity 13, and then pass through the No. 1 gas flow cavity 15 into the exhaust equipment, and be discharged outward through the exhaust equipment, and the filtered particulate matter will adhere to the outer surface of the filter screen 19, thereby achieving the filtering effect of the flowing exhaust gas.

[0029] For the specific structure of the rotary exhaust gas filtering mechanism 1, please refer to Figure 3 and Figure 4, including a No. 1 docking plate 12 arranged at the center of the upper end surface of the polyhedron shell 11, a docking channel structure 14 with an integral structure therewith is provided at the bottom of the polyhedron shell 11, a filter cavity 13 is provided inside the polyhedron shell 11, a No. 1 gas flow cavity 15 with an open bottom end and a top end connected to the bottom port of the filter cavity 13 is provided inside the docking channel structure 14, a plurality of annular hollow bodies 16 with an integral structure therewith are provided on the vertical surface of the polyhedron shell 11, a No. 2 gas flow cavity 17 with one outer end being open and the other end connected to the filter cavity 13 is provided inside the annular hollow body 16, and the outer periphery of the port of the annular hollow body 16 is mounted on a hollow roller 18 through a bearing. Inside, a filter screen 19 is fixedly installed inside the hollow roller 18, and a rubber follower ring 110 is fixedly embedded in the middle of the outer circumference of the hollow roller 18. The top of the docking channel structure 14 and the bottom end of the polyhedron shell 11 are transitionally connected by a conical structure, and the filter cavity 13 and the No. 1 gas flow cavity 15 are transitionally connected by a conical structure. The docking channel structure 14 is provided with an annular structure on the periphery near its bottom port. When working, the annular structure of the docking channel structure 14 is connected to the exhaust port of an exhaust device through a bearing and a sealing ring. The rubber follower ring 110 is made of hard rubber material, and the outer circumference of the rubber follower ring 110 protrudes outward relative to the outer circumference of the hollow roller 18.

[0030] In order to make the filter 19 produce a stronger centrifugal effect under the dual rotation effect of revolution and rotation, thereby improving the cleaning effect and efficiency of particulate matter, please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 , it is necessary to set up a resistance support mechanism 2, which is provided with a resistance ring body 28 fixedly installed at the bottom of the rubber driven ring 110 and capable of rotating the rubber driven ring 110 when rotating, a driving motor 26 located just above the polyhedron shell 11 and capable of driving the polyhedron shell 11 to rotate, and an upper longitudinal support rod 24 capable of fixedly supporting the driving motor 26. When the driving motor 26 is started, its rotor will drive the polyhedron shell 11 to rotate rapidly. At this time, the filter screen 19 will produce an orbital phenomenon around the rotor axis. At the same time, relative friction will occur between the bottom of the rubber driven ring 110 at the revolution end and the upper surface of the resistance ring body 28. Since the static friction between the resistance ring body 28 and the rubber driven ring 110 is sufficient to make the rubber driven ring 110 produce a self-rotation effect while revolving, under the dual rotation of self-rotation and revolution, the particles attached to the surface of the filter screen 19 will produce a strong centrifugal effect, so that the particles attached to and blocked in the filter screen 19 are thrown out, thereby improving the cleaning effect and efficiency of the particles.

[0031] For the specific structure of the contact support mechanism 2, please refer to Figure 5 and Figure 6 , including a lower support leg 21 fixedly mounted on the bottom of the resistance ring body 28 and having a ground support effect, the resistance ring body 28 resists the bottom area of the rubber driven ring 110, and the static friction between the resistance ring body 28 and the rubber driven ring 110 is sufficient to make the rubber driven ring 110 produce a rotation effect while revolving, and a lower horizontal support plate 22 in a horizontal state is fixedly mounted on the middle part of the lower support leg 21, and an upper horizontal support plate 23 is fixedly mounted on the upper surface of the lower horizontal support plate 22 through an upper longitudinal support rod 24, and a motor fixing sleeve 25 is fixedly mounted at the center of the upper horizontal support plate 23, and the drive motor 26 is fixedly mounted inside the motor fixing sleeve 25, and a second docking plate 27 is fixedly mounted on the rotor end of the drive motor 26.

[0032] In order to achieve the linkage effect of the polyhedron shell 11 and generate downward elastic pressure, so that the filter 19 can produce a self-rotation effect under the action of sufficient friction, please refer to Figure 1 、 Figure 2 、 Figure 7 and Figure 8 , it is necessary to set up a telescopic linkage mechanism 3, which is provided with a longitudinal hollow shell 31 which can rotate with the second docking plate 27 and is in a hollow state inside, a built-in movable plate 35 located inside the longitudinal hollow shell 31 and can rotate with the longitudinal hollow shell 31, a longitudinal telescopic rod 37 which can rotate with the built-in movable plate 35 and drive the built-in movable plate 35 to produce a longitudinal movement effect, and a fourth docking plate 38 which can rotate with the longitudinal telescopic rod 37 and drive the first docking plate 12 to rotate. The rotor of the driving motor 26 will drive the longitudinal hollow shell 31 to rotate rapidly. At the same time, the longitudinal The hollow shell 31 can drive the polyhedron shell 11 to rotate through the built-in movable plate 35 and the longitudinal telescopic rod 37, thereby achieving the necessary linkage effect. At the same time, the compressed coil spring 36 will generate a downward force on the built-in movable plate 35, and the force will be gradually transmitted until it is transmitted between the resistance ring body 28 and the rubber driven ring 110, so as to increase the maximum static friction between the resistance ring body 28 and the rubber driven ring 110, so as to ensure that when relative motion occurs between the two, the rubber driven ring 110 drives the filter screen 19 to produce a self-rotation effect.

[0033] For the specific structure of the telescopic linkage mechanism 3, please refer to Figure 7 and Figure 8, including a third docking plate 32 integrally arranged on the top of the longitudinal hollow shell 31 and fixedly connected to the second docking plate 27, a longitudinal component movable cavity 33 is provided inside the longitudinal hollow shell 31, and a rod body through-hole 34 is provided at the bottom end of the longitudinal hollow shell 31 to connect the bottom end of the longitudinal component movable cavity 33 and the space below it, and the longitudinal hollow shell 31 is provided with a built-in movable plate 35 capable of axial movement along the longitudinal component movable cavity 33 inside the longitudinal component movable cavity 33, and a longitudinal telescopic rod 37 penetrating the rod body through-hole 34 is fixedly installed at the bottom end of the built-in movable plate 35. A No. 4 docking plate 38 is fixedly installed at the bottom end of 37, and the No. 4 docking plate 38 is fixedly connected to the No. 1 docking plate 12. A coil spring 36 in a compressed state is fixedly installed above the built-in movable plate 35. The top end of the coil spring 36 abuts against the top end of the longitudinal component movable cavity 33, and the bottom end abuts against the upper surface of the built-in movable plate 35. The structural shape of the cross section of the longitudinal component movable cavity 33 is consistent with the structural shape of the cross section of the built-in movable plate 35, both of which are polygonal structures, and the structural dimensions of the cross section of the longitudinal component movable cavity 33 match the structural dimensions of the cross section of the built-in movable plate 35.

[0034] When in use, the annular structure of the docking channel structure 14 is connected to the exhaust port of an exhaust device through a bearing and a sealing ring, and then the device is moved to a closed space for exhaust gas discharge, and the exhaust device is turned on. The exhaust gas in the external environment will be filtered through the filter 19 and enter the filter cavity 13, and then enter the exhaust device through the No. 1 gas flow cavity 15, and be discharged outward through the exhaust device, and the filtered particulate matter will adhere to the outer surface of the filter 19. At the same time, the drive motor is started, and the rotor of the drive motor 26 will drive the longitudinal hollow shell 31 to rotate rapidly, and the longitudinal hollow shell 31 can be rotated rapidly through the built-in movable plate 35 and the longitudinal telescopic The rod 37 drives the polyhedron shell 11 to rotate, and the filter screen 19 will revolve around the axis of the rotor. At the same time, relative friction will be generated between the bottom of the rubber follower ring 110 at the orbiting end and the upper surface of the resistance ring body 28. Since the static friction between the resistance ring body 28 and the rubber follower ring 110 is sufficient to make the rubber follower ring 110 produce a self-rotation effect while revolving, under the dual rotation of self-rotation and revolution, the particulate matter attached to the surface of the filter screen 19 will produce a strong centrifugal effect, so that the particulate matter attached to and blocked in the filter screen 19 will be thrown out, thereby improving the cleaning effect and efficiency of the particulate matter.
