Description

Technical Field

[0001] The invention relates to the technical field of asphalt emulsifier preparation, and in particular to waste gas treatment equipment of an asphalt emulsifier processing line. Background Art

[0002] Asphalt emulsifier is a surfactant used for asphalt emulsification. During its processing, a large amount of waste gas is generated, which needs to be treated by a waste gas treatment device. However, during the use of existing waste gas treatment devices, the activated carbon adsorption block is inconvenient to replace, resulting in a decrease in adsorption capacity, which affects the subsequent waste gas treatment effect.

[0003] Chinese patent CN221471431 U discloses a waste gas treatment device for preparing asphalt emulsifier. The device includes a tank body, an air inlet pipe is provided on the left side of the tank body, a water outlet is provided at the lower end, and a connecting pipe is provided on the right side of the top. The device also includes a spraying mechanism, a reflux mechanism and an adsorption mechanism. The spraying mechanism is installed inside the tank body for cooling the waste gas; the reflux mechanism is arranged on one side of the tank body for recovering and recycling the liquid; the adsorption mechanism is connected to the tank body through a connecting pipe for adsorbing harmful substances in the waste gas. This patent sets a spraying mechanism and drives the rotating tube to rotate by a motor so that the liquid is evenly sprayed inside the tank body, thereby cooling the waste gas and improving the adsorption effect of the activated carbon adsorption block. However, in the prior art, after the filter assembly is used for a long time, a large amount of impurities will be adsorbed on the surface, affecting the filtration efficiency. If it is not cleaned in time, the effect of the filter assembly will gradually decrease, and it may even block the waste gas channel, resulting in the inability to effectively treat the waste gas. The traditional spray tower design usually relies on regular shutdown maintenance and manual cleaning of impurities on the filter assembly. This maintenance method is not only inefficient, but also causes the equipment to shut down for a long time, affecting production efficiency. In addition, since the filter components often use porous structures or filling materials, impurities easily accumulate on the surface of the filler, and it is impossible to ensure that the filter components can still maintain an efficient working state after a long period of use.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides a rotatable filter component and a spray component in the spray tower, and can achieve online cleaning of the filter component by switching the reactant and the detergent and coordinating the rotating action of the filter component, thereby avoiding the disadvantages of low cleaning efficiency or the need to shut down the equipment for cleaning in traditional technologies. The diaphragm is transformed in shape by the movement of the drive shaft, so that it is transformed from an inverted funnel shape in the initial state to a funnel shape. During the cleaning process, the residual impurities and detergents from the cleaning can be more effectively introduced into the collection tank, thereby improving the collection efficiency of impurities during the cleaning process and avoiding contamination of other components. The automatic rotation and cleaning of the filter component are achieved by setting the drive shaft and the transmission component of the filter component in combination with the automatic spraying and collecting mechanism, thereby reducing manual intervention, improving the intelligence level of the equipment, and reducing the difficulty of manual operation.

[0017] 2. In the present invention, through the setting of the transmission component, the second toothed disc on the driving shaft is meshed with the first toothed disc on the filtering component, and the driving shaft can effectively control the rotation of the filtering component. When the driving shaft moves along the axis of the spray tower and meshes with the toothed disc, the driving shaft transmits power to the filtering component through rotation, thereby realizing the rotation of the filtering component. By cooperating with the spray component to switch the reactant and the cleaning agent, it is ensured that the impurities adsorbed on the surface of the filtering component are efficiently cleaned.

[0018] 3. The present invention avoids contamination or corrosion of the toothed disc by the spray liquid or cleaning liquid during the cleaning process by setting a retractable protective cover. This method prolongs the service life of the toothed disc and greatly reduces unexpected shutdowns and maintenance due to equipment wear, corrosion and other problems. In addition, the design of the stirring rod at the bottom of the spray tower also fully considers the cleaning effect. Through the coordinated work of the stirring rod and the filter assembly, the filling material can be stirred and cleaned more thoroughly, ensuring the long-term stability of the filtering effect.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figures 1 to 4 , Fig. 9 and Fig.10 As shown: an exhaust gas treatment device for an asphalt emulsifier processing line, comprising a spray tower 1 and a spray assembly 11 and a filter assembly 12 arranged in the spray tower 1, the spray assembly 11 is respectively provided with a first pipe 111 connected to an external reactant and a second pipe 112 connected to an external cleaning agent; the filter assembly 12 is rotatably arranged below the spray assembly 11; a diaphragm 21, a collecting tank 13 and a drive shaft 2 that can slide along the axial direction of the spray tower 1 are arranged below the filter assembly 12 The driving shaft 2 is rotatably arranged in the center of the spray tower 1 and is coaxially arranged therewith. A transmission assembly 22 for driving the filter assembly 12 to rotate is arranged on the top of the driving shaft 2. The collecting tank 13 is arranged on the inner wall of the spray tower 1. The diaphragm 21 is a retractable circular structure. The diaphragm 21 is arranged between the collecting tank 13 and the driving shaft 2, and a channel 23 for the exhaust gas to pass through is left between the diaphragm 21 and the driving shaft 2. The diaphragm 21 can change from a funnel shape in the initial state to an inverted funnel shape as the driving shaft 2 moves.

[0032] When the equipment is treating the exhaust gas, the diaphragm 21 is in a funnel-shaped structure in the initial state, and the exhaust gas will enter the filter component 12 along the bottom of the diaphragm 21 from the channel 23 between the diaphragm 21 and the drive shaft 2, and be filtered through the filter component 12 in the spray tower 1. At this time, the spray component 11 is connected to the reactant through the first pipe 111, and the reactant can purify the exhaust gas. Since the surface of the filter component 12 will gradually absorb impurities during the filtering process, long-term operation may affect the filtering effect. When too many impurities accumulate in the filter component 12, the equipment enters the online cleaning stage of the filter component 12. At this time, the drive shaft 2 slides toward the filter component 12 along the axial direction of the spray tower 1, and abuts against the filter component 12 through the transmission component 22 on the drive shaft 2, and drives the filter component 12 to rotate through the transmission component 22. At the same time, the spray component 11 Switch to the second pipe 112. At this time, the spray component 11 will spray the cleaning agent connected to the outside, and the filter component 12 will be cleaned by the cleaning agent. Due to the movement of the driving shaft 2, the diaphragm 21 changes from the funnel shape in the initial state to an inverted funnel shape. At this time, the cleaning agent will fall on the diaphragm 21 after cleaning the filter component 12. Through the structure of the diaphragm 21, the impurities flushed down will move along the inner wall of the diaphragm 21 to the collecting tank 13 on the inner wall of the spray tower 1, and the impurities and excess cleaning agent fallen off the filter component 12 will be guided to the collecting tank 13 on the inner wall of the spray tower 1, thereby effectively preventing the diffusion and pollution of impurities. The cleaning process of this equipment does not require shutdown, and can be started at any time according to the use of the filter component 12, ensuring the continuous and efficient operation of the equipment, and can conveniently collect and treat impurities and waste liquid after cleaning.

[0033] By providing a rotatable filter assembly 12 and a spray assembly 11 in the spray tower 1, the filter assembly 12 can be cleaned online by switching the reactant and the cleaning agent in coordination with the rotation of the filter assembly 12, thereby avoiding the disadvantages of low cleaning efficiency or the need to shut down the equipment for cleaning in traditional technologies; online cleaning of the filter assembly 12 can effectively reduce the accumulation of impurities in the exhaust gas, improve the filtration efficiency, and reduce the risk of equipment damage or blockage due to impurity accumulation, extend the service life of the equipment, and reduce maintenance costs; the diaphragm 21 is transformed in shape by the movement of the drive shaft 2, so that it changes from the funnel shape in the initial state to an inverted funnel shape, and during the cleaning process, the residual impurities and cleaning agents can be more effectively introduced into the collection tank 13, thereby improving the impurity collection efficiency during the cleaning process and avoiding contamination of other components.

[0034] like Figures 2 to 10As shown: a support frame 211 for supporting the diaphragm 21 is arranged on the driving shaft 2, and the support frame 211 is composed of a plurality of retractable connecting rods 212, and the plurality of connecting rods 212 are equidistantly arranged around the axis of the driving shaft 2, and the two ends of the connecting rods 212 are respectively hinged to the driving shaft 2 and the collecting tank 13, and the collecting tank 13 and the driving shaft 2 are both provided with mounting grooves 213 for fixing the two ends of the diaphragm 21.

[0035] By arranging a support frame 211 on the driving shaft 2, and the support frame 211 is composed of a plurality of retractable connecting rods 212, the diaphragm 21 can remain stable during movement. The plurality of connecting rods 212 are evenly distributed around the driving shaft 2, which can effectively prevent the diaphragm 21 from deflecting or deforming when sliding up and down on the driving shaft 2, thereby ensuring its normal operation. The retractability of the support frame 211 allows the diaphragm 21 to flexibly adjust its shape in different states. When the diaphragm 21 changes from a funnel shape to an inverted funnel shape, the connecting rods 212 can automatically adapt to the changes of the diaphragm 21, so that the diaphragm 21 can be moved smoothly. The shape adjustment of 21 is smoother. The two ends of the connecting rod 212 are respectively hinged to the drive shaft 2 and the collecting tank 13, so that the diaphragm 21 can be more accurately adjusted to the predetermined collection position under the action of the support frame 211. The shape change of the diaphragm 21 helps to improve the collection efficiency of impurities and cleaning agents and prevent impurities from leaking to other parts of the equipment. Multiple telescopic connecting rods 212 are evenly distributed, which can disperse the stress on the diaphragm 21 during movement and avoid local damage or premature wear of the diaphragm 21, thereby extending the service life of the diaphragm 21 and the supporting mechanism.

[0036] like Figures 2 to 7 As shown: the collecting tank 13 is an annular structure, and a plurality of recovery holes 131 for collecting the cleaning liquid are arranged on one side of the collecting tank 13 close to the driving shaft 2 , and the plurality of recovery holes 131 are arranged equidistantly around the axis of the spray tower 1 .

[0037] By setting the collecting tank 13 as an annular structure, it can better fit the inner wall of the spray tower 1, ensuring that when the diaphragm 21 is transformed into an inverted funnel, the cleaning liquid and impurities left by the filter component 12 can leave the collecting tank 13 along the diaphragm 21; the equidistant setting of the recovery holes 131 ensures that the cleaning liquid can be quickly collected after spraying and will not be retained in the tank, reducing the waste of cleaning liquid, and preventing it from falling directly into the recovery liquid at the bottom of the spray tower 1, which can reduce the need for the recovery liquid to be filtered and recovered after mixing with the cleaning liquid. Since the recovery holes 131 are evenly distributed on one side close to the drive shaft 2, the flow of the cleaning liquid in the recovery tank is more orderly, which can effectively prevent liquid accumulation and overflow, especially the large amount of liquid generated during the cleaning process can be discharged in time through the recovery holes 131, preventing the overflow in the tank from affecting the operation of the equipment, and quickly collecting the cleaning liquid with impurities to prevent the impurities from being deposited in the filter component 12 or the tower body, which can greatly improve the cleaning efficiency and ensure that the filter component 12 can resume working condition in a shorter time.

[0038] like Figures 2 to 10 As shown: the transmission assembly 22 includes a first toothed disc 221 and a second toothed disc 222. The first toothed disc 221 is fixedly connected to the bottom center of the filter assembly 12, and the second toothed disc 222 is fixedly connected to the top of the drive shaft 2. When the drive shaft 2 slides toward the filter assembly 12 along the axial direction of the spray tower 1, it can drive the second toothed disc 222 to dock with the first toothed disc 221. At this time, the first toothed disc 221 and the second toothed disc 222 are meshed and connected.

[0039] The filter assembly 12 is generally provided with a spherical granular adsorption filler 123, which can drive the filler 123 to move when rotating, thereby playing a certain cleaning role for the filler 123. When the drive shaft 2 moves to the side of the filter assembly 12 along the axial direction of the spray tower 1, through the meshing connection between the first toothed disc 221 and the second toothed disc 222, the transmission assembly 22 can automatically transmit the power of the drive shaft 2 to the filter assembly 12, so that the filter assembly 12 rotates, and the filter material on the filter assembly 12 can rotate, thereby facilitating the online cleaning of the filter assembly 12, reducing manual intervention, and improving the degree of automation of the equipment; the meshing transmission of the first toothed disc 221 and the second toothed disc 222 has efficient power transmission capability, which can ensure that the filter assembly 12 responds quickly when it needs to rotate, effectively improving the working efficiency of the equipment, and shortening the time for cleaning and maintenance.

[0040] like Figures 2 to 8 and Fig.10 As shown: a proximity sensor 214 is arranged on the top of the driving shaft 2, and a mounting box 121 for fixing the first toothed disc 221 is arranged on the filter assembly 12.

[0041] When the drive shaft 2 moves along the axial direction of the spray tower 1, the proximity sensor 214 on the top of the drive shaft 2 will be driven to approach the mounting box 121 of the filter assembly 12. At this time, the proximity sensor 214 provides real-time feedback to ensure that the first toothed disc 221 and the second toothed disc 222 are docked smoothly, avoiding the problem that the first toothed disc 221 and the second toothed disc 222 cannot be engaged or misaligned, reducing human intervention, realizing intelligent automatic control and operation, and improving the automation level of the equipment. When the docking is completed, the proximity sensor 214 sends a signal to the rear-end controller, and the controller drives the drive shaft 2 to rotate, thereby enabling the second toothed disc 222 on the drive shaft 2 to transmit power to the first toothed disc 221 on the filter assembly 12 by rotation. The role of the proximity sensor 214 is not only to provide positioning, but also to ensure that the transmission system is started under appropriate conditions, reduce mechanical damage caused by poor gear meshing or impact force, thereby improving the safety and reliability of equipment operation, preventing the drive shaft 2 and the toothed disc from rotating by mistake when not docked, avoiding damage to the transmission assembly 22, and extending the service life of the equipment.

[0042] like Figures 2 to 10 As shown: the second toothed disc 222 is provided with a sleeve 2222 extending toward the drive shaft 2 along its axial direction, the bottom of the sleeve 2222 is provided with a plug 2221 capable of blocking the channel 23, the plug 2221 is provided with an axial hole 2223 matching the drive shaft 2, the sleeve 2222 and the plug 2221 are both sleeved on the drive shaft 2, a limit plate 24 is provided on the top of the drive shaft 2, and an elastic member 241 is provided between the limit plate 24 and the second toothed disc 222.

[0043] In the initial state, due to the setting of the elastic member 241, the second toothed disc 222 can be located beside the limit plate 24 under the action of the elastic member 241. At this time, a gap is left between the plug 2221 and the channel 23, so that the exhaust gas can enter between the diaphragm 21 and the filter assembly 12 through the channel 23. When the filter assembly 12 needs to be cleaned online, the drive shaft 2 moves along the axial direction of the spray tower 1. At this time, the drive shaft 2 will drive the second toothed disc 222 to mesh with the first toothed disc 221. Since the second toothed disc 222 is sleeved on the drive shaft 2, when the second toothed disc 222 is behind the first toothed disc 221, the second toothed disc 222 cannot continue to move with the drive shaft 2, and the drive shaft 2 will continue to move upward, so that the channel 2 on the drive shaft 2 3 is moved closer to the plug 2221 until the plug 2221 blocks the channel 23. At this time, the drive shaft 2 stops moving, and the elastic member 241 is stretched. Through the arrangement of the sleeve 2222 and the plug 2221, when the drive shaft 2 moves up to a specific position, the plug 2221 can accurately block the channel 23, ensuring that the blocking operation is performed at an appropriate time. At this time, it is helpful to control the exhaust gas, so that the exhaust gas cannot enter the filter component 12 during the self-cleaning period, thereby improving the cleaning effect of the filter component 12. At the same time, the blockage of the channel 23 makes it possible for the cleaning liquid to not flow into the bottom of the spray tower 1 along the channel 23 during the self-cleaning period, thereby reducing the need for filtering and recycling the recovery liquid after it is mixed with the cleaning liquid.

[0044] The setting of the elastic member 241 enables the second toothed disc 222 to be pulled to the vicinity of the limit plate 24 in the initial state, leaving a certain gap. This automatic adjustment function enables the device to flexibly block or release when needed, providing an automated blocking control method. The elastic member 241 can absorb part of the impact force in the mechanical movement, reduce the wear on the toothed disc, drive shaft 2 and other transmission components, extend the service life of the equipment, and maintain stable operation of the equipment even under frequent operation.

[0045] It should be noted that the inner walls of the sleeve 2222 and the second toothed disc 222 are both provided with keyways which are not shown in the figure, and the drive shaft 2 is provided with protrusions which match the keyways which are not shown in the figure. The setting of the keyways and protrusions ensures that power can be transmitted between the two while sliding.

[0046] like Figure 2 , Figure 3 and Fig.10 As shown, a retractable protective cover 122 is provided between the first toothed disc 221 of the filter assembly 12 and the second toothed disc 222 of the drive shaft 2 , and both the first toothed disc 221 and the second toothed disc 222 are located inside the protective cover 122 .

[0047] By wrapping the first toothed disc 221 and the second toothed disc 222 with the protective cover 122, it is possible to effectively prevent spray liquid or cleaning liquid from entering the transmission component 22, and prevent the liquid from contaminating or corroding the surface of the toothed disc, thereby ensuring the smoothness and accuracy of the gear meshing and extending the service life of the equipment. Due to the presence of the protective cover 122, the possibility of the toothed disc surface being contaminated by liquid is reduced, the frequency of cleaning and maintenance is reduced, the equipment downtime is reduced, and the overall working efficiency of the equipment is improved. The protective cover 122 is retractable and can adapt to the change in the spacing between the first toothed disc 221 and the second toothed disc 222, thereby ensuring the normal operation of the transmission component 22 and maintaining good sealing. It will not affect the rotation and meshing of the toothed disc, and effectively improves the overall reliability and performance of the equipment.

[0048] like Figures 2 to 6 As shown, the spray assembly 11 is provided with a plurality of stirring rods 113 extending along the axis direction of the spray tower 1 , and the stirring rods 113 are arranged around the axis of the spray tower 1 at equal intervals.

[0049] The stirring rods 113 are equidistantly arranged around the axis of the spray tower 1, so that when the filter assembly 12 rotates, the filler 123 on the filter assembly 12 can be evenly stirred and cleaned during the rotation process, avoiding the cleaning blind spot that causes the local cleaning of the filler 123 to be inadequate, ensuring the consistent cleaning effect of the entire filter assembly 12, and the stirring rod 113 stirs the filler 123 to prevent the filler 123 from piling up due to sedimentation or pressure during the filtration process, maintain the looseness of the filler 123, and avoid agglomeration or physical damage of the filler 123 due to long-term immobility, thereby improving the filtration efficiency and the operating stability of the equipment, helping to ensure the activity and service life of the filler 123, reducing the maintenance cost and the replacement frequency of the filler 123, the stirring rod 113 enables the filler 123 to move continuously during the filtration and cleaning process, increasing the contact area between the filler 123 and the detergent and reactant, thereby improving the efficiency and reaction effect of the exhaust gas treatment, and further improving the processing capacity of the equipment.

[0050] like Figures 1 to 8 As shown: a hexagonal prism 25 extending along the axial direction of the driving shaft 2 is provided at the bottom, a driving ring 251 slidingly matched therewith is provided on the hexagonal prism 25, a rotating shaft 26 for driving the driving ring 251 is provided on the side of the driving ring 251, a first rotating driving motor 262 transmission-connected therewith is provided on the rotating shaft 26, and a synchronous belt 261 is sleeved on the rotating shaft 26 and the driving ring 251.

[0051] Through the setting of the sliding fit between the hexagonal prism 25 and the drive ring 251, the shape of the hexagonal prism 25 can increase the transmission contact surface and closely fit with the drive ring 251, thereby enhancing the efficiency of torque transmission, reducing energy loss, and making power transmission more efficient, ensuring that the drive shaft 2 maintains stability during the up and down movement, preventing shaking or deviation during rotation, and ensuring the smoothness and accuracy of the transmission process. By starting the first rotary drive motor 262, the output shaft of the first rotary drive motor 262 can drive the rotation of the rotating shaft 26, and the rotation of the rotating shaft 26 drives the rotation of the synchronous belt 261, and the rotation of the drive ring 251 is driven by the synchronous belt 261, thereby ensuring that the hexagonal prism 25 can control the rotation of the drive shaft 2, ensuring the accurate movement of the filter component 12 or other rotating parts, and improving the operating accuracy of the equipment.

[0052] like Figures 1 to 8 As shown: the bottom of the spray tower 1 is also provided with a mounting frame 14, and the driving ring 251 is rotatably arranged on the mounting frame 14. A lifting plate 141, a screw rod 142 and a guide rod 143 are arranged between the mounting frame 14 and the bottom of the spray tower 1. The axes of the screw rod 142 and the guide rod 143 are parallel to the axis of the spray tower 1. The lifting plate 141 is sleeved on the screw rod 142 and threadedly matched with it. The lifting plate 141 is sleeved on the guide rod 143 and slidably matched with it. The driving shaft 2 is sleeved on the lifting plate 141 and can be driven by it.

[0053] Through the threaded cooperation between the screw rod 142 and the lifting plate 141, the precise lifting and lowering adjustment of the drive shaft 2 can be achieved, ensuring the accuracy of the equipment when running at different heights, which helps to better match the working requirements inside the spray tower 1. The sliding cooperation design of the guide rod 143 of the lifting plate 141 can provide additional support and guidance during the lifting process, preventing the drive shaft 2 or the lifting plate 141 from tilting or swinging during lifting, thereby increasing the stability and reliability of the equipment operation. The movement of the lifting plate 141 drives the drive shaft 2 to move along the axial direction of the spray tower 1, thereby realizing the state change of the diaphragm 21 and the transmission of the filter component 12.

[0054] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
