Description

Technical Field

[0001] This utility model belongs to the field of asphalt processing technology, and relates to dust removal in asphalt processing, specifically a dust removal device for asphalt processing. Background Technology

[0002] Dust and impurities adhere to the surface of asphalt, which can negatively affect the quality of the final product. Therefore, it needs to be cleaned. Cleaning can ensure the purity of the asphalt, thereby improving its performance and durability. Cleaning to remove dust is a very important part of the asphalt processing, which helps to ensure the high quality of the product and the smooth progress of processing. Dust removal devices are generally used.

[0003] A search revealed a Chinese patent document disclosing a dust removal device for asphalt processing [Application No.: CN202420424470.X; Publication No.: CN221869527U]. This device includes a cleaning tank and a drain pipe. The drain pipe is fixedly connected to the lower right side of the cleaning tank, and a cap is attached to the right end of the drain pipe. Dust removal mechanisms are connected to both the inner and outer ends of the cleaning tank. These mechanisms include a cleaning unit and a drying unit, with the cleaning unit located at the top of the cleaning tank. In use, the modified asphalt concrete recycled material to be dusted is first poured into the cleaning frame. Then, the telescopic component is activated, causing its output shaft to move downwards, which in turn moves the slider down along the limiting rod. This causes the connecting plate at the outer end of the slider to move downwards as well, thereby moving the sleeve plate and the cleaning frame downwards together until the cleaning frame is lowered into the cleaning tank and cleaned by the cleaning water. Then, the telescopic component is activated again to move the cleaning frame upwards out of the cleaning tank.

[0004] Although the dust removal device disclosed in this patent can clean asphalt by moving the cleaning tank up and down, the asphalt accumulates inside the cleaning tank. The up-and-down movement of the cleaning tank alone results in limited contact between the cleaning liquid and the asphalt. The cleaning liquid cannot penetrate deep enough, making it difficult for the asphalt to fully contact the cleaning liquid. The cleaning effect is not ideal and cannot effectively remove dust and impurities. Therefore, it is necessary to design a dust removal device for asphalt processing to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a dust removal device for asphalt processing. The technical problem to be solved by this utility model is: how to improve the effect of cleaning and removing dust from asphalt.

[0006] The objective of this utility model can be achieved through the following technical solutions: A dust removal device for asphalt processing includes a cleaning box. Mounting frames are fixedly connected to both sides of the cleaning box. Lifting platforms are slidably connected to the inner walls of both mounting frames. Two positioning slots are formed at one end of each lifting platform. Positioning rods are installed within the positioning slots. The tops of the two positioning rods at the same end are fixedly connected to the same L-shaped plate. The two L-shaped plates are fixedly connected to the same frame on their adjacent sides. Fixed rods are fixedly connected to both ends of the frame. Moving blocks are fitted onto both fixed rods. The moving blocks slidably connect the fixed rods and the frame. A cleaning frame is fixedly connected to the bottom of the two moving blocks. Springs are provided on both sides of each moving block, and fixed rods are fitted onto the springs. Fixed shafts are fixedly connected to both sides of the bottom end of the cleaning frame. First rollers are fitted onto the fixed shafts. The first rollers are rotatably connected to the fixed shafts. A wavy guide plate is provided on one side of the first roller, and one side of the wavy guide plate is wavy.

[0007] The working principle of this utility model is as follows: Asphalt is placed into the cleaning frame, and a positioning rod is inserted into the positioning groove to position the cleaning frame. The positioning rod is stably positioned in the positioning groove by the weight of the cleaning frame. Then, the lifting platform is lowered, and the L-shaped plate also lowers as the lifting platform lowers. The L-shaped plate drives the frame to lower, the frame drives the fixed rod to lower, the fixed rod drives the moving block to lower, the moving block drives the cleaning frame to lower, the cleaning frame drives the fixed shaft to lower, and the fixed shaft drives the first roller to lower. If the first roller continues to descend after contacting the corrugated guide plate, the first roller can move laterally back and forth during the descent. The first roller drives the fixed shaft to move, and the fixed shaft drives the cleaning frame to move. The cleaning frame moves laterally back and forth during the descent or ascent, causing the asphalt in the cleaning frame to spread out and fully contact the water, thereby thoroughly cleaning the asphalt and removing the dust attached to the surface. When the cleaning frame moves laterally, it drives the moving block to move, and the moving block compresses the spring. As the first roller moves along the corrugated guide plate, the spring will continuously contract and expand, ensuring that the cleaning frame can continuously move laterally.

[0008] As a further embodiment of this utility model, a pin is provided on the lifting platform, the pin is slidably connected to the lifting platform, slots are provided at both ends of the L-shaped plate, the pin is adapted to the slots, and the same fixed seat is fixedly connected to the same side of the two pins at the same end. A second roller is rotatably connected to the fixed seat, and an L-shaped guide plate is provided on one side of the second roller. One side of the L-shaped guide plate is inclined, and the L-shaped guide plate is fixedly connected to the mounting bracket.

[0009] With the above structure, when the lifting platform descends, the lifting platform also drives the pin to descend, the pin drives the fixed seat to descend, the fixed seat drives the second roller to descend, and the second roller moves along the inclined surface of the L-shaped guide plate. This allows the second roller to move closer to the lifting platform, which in turn allows the pin to move closer to the L-shaped plate. When the second roller moves past the inclined surface of the L-shaped guide plate and reaches the vertical surface of the inner wall of the L-shaped guide plate, the pin will insert into the slot, thus restricting and fixing the L-shaped plate, which in turn fixes the cleaning frame. This also ensures the stability of the cleaning frame when it moves laterally.

[0010] As a further embodiment of this utility model, the inner walls on both sides of the mounting frame are provided with sliding grooves, and sliders are provided in the sliding grooves. The sliders are slidably connected to the mounting frame and fixedly connected to the lifting platform.

[0011] With the above structure, when the lifting platform moves up and down, it will drive the slider to move along the slide groove, ensuring the stability of the lifting platform when moving up and down.

[0012] As a further embodiment of this utility model, a cylinder is fixedly connected to the top of each of the two mounting brackets, and the output end of the cylinder is fixedly connected to a lifting platform. The two cylinders are connected to the same air supply system.

[0013] As a further embodiment of this utility model, a water outlet pipe is provided on one side of the bottom of the cleaning tank, and the water outlet pipe is connected to the cleaning tank.

[0014] As a further embodiment of this utility model, a valve is provided on the water outlet pipe.

[0015] Compared with the prior art, the dust removal device for asphalt processing of this utility model has the following advantages: In this invention, the technical means of allowing the cleaning frame to move laterally back and forth during the rising and falling process is adopted. This lateral back and forth movement allows the asphalt inside the cleaning frame to disperse, avoiding cleaning blind spots caused by accumulation. This enables the asphalt to fully contact the cleaning liquid to remove dust and impurities, effectively solving the problem in the background technology where the contact between the cleaning liquid and the asphalt is limited due to the cleaning box only moving up and down. The cleaning liquid cannot penetrate deep, resulting in insufficient contact between the asphalt and the cleaning liquid, and the cleaning effect is not ideal, failing to effectively remove dust and impurities. Thus, this invention achieves the technical effect of enabling the asphalt to fully contact the cleaning liquid, more effectively removing surface dust and impurities, improving the cleaning effect, reducing the cleaning time required, and improving the overall work efficiency.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figures 1-4As shown, a dust removal device for asphalt processing includes a cleaning box 1. Mounting frames 2 are fixedly connected to both sides of the cleaning box 1. Lifting platforms 3 are slidably connected to the inner walls of both mounting frames 2. Two positioning grooves 4 are opened at one end of each lifting platform 3. Positioning rods 5 are installed in the positioning grooves 4. The tops of the two positioning rods 5 at the same end are fixedly connected to the same L-shaped plate 6. The two L-shaped plates 6 are fixedly connected to the same frame 7 on their adjacent sides. Fixing rods 8 are fixedly connected to both ends of the frame 7. Moving blocks 9 are fitted onto both fixing rods 8, and the moving blocks 9 slidably connect the fixing rods 8 and the frame 7. A cleaning frame 10 is fixedly connected to the bottom of the two moving blocks 9. Springs 11 are installed on both sides of each moving block 9, and the springs 11 are fitted onto the fixing rods 8. Fixed shafts 12 are fixedly connected to both sides of the bottom end of the cleaning frame 10. First rollers 13 are fitted onto the fixed shafts 12, and the first rollers 13 are rotatably connected to the fixed shafts 12. A wave-shaped guide plate 14 is installed on one side of the first rollers 13. One side of the wavy guide plate 14 is wavy. A pin 15 passes through the lifting platform 3 and slides on it. Both ends of the L-shaped plate 6 have slots 16, which are matched with the pins 15. The same side of the two pins 15 at the same end is fixedly connected to the same fixing seat 17. A second roller 18 is rotatably connected to the fixing seat 17. An L-shaped guide plate 19 is provided on one side of the second roller 18. One side of the L-shaped guide plate 19 is inclined. The mounting bracket 2 is fixedly connected. The inner walls of both sides of the mounting bracket 2 are provided with sliding grooves 20. The sliding grooves 20 are provided with sliders 21. The sliders 21 are slidably connected to the mounting bracket 2 and fixedly connected to the lifting platform 3. The top of the two mounting brackets 2 are fixedly connected with cylinders 22. The output end of the cylinders 22 is fixedly connected to the lifting platform 3. The two cylinders 22 are connected to the same air supply system. A water outlet pipe 23 is provided on one side of the bottom of the cleaning box 1. The water outlet pipe 23 is connected to the cleaning box 1 and a valve is provided on the water outlet pipe 23.

[0020] The working principle of this utility model is as follows: Asphalt is placed into the cleaning frame 10, and the positioning rod 5 is inserted into the positioning groove 4 to position the cleaning frame 10. The weight of the cleaning frame 10 ensures that the positioning rod 5 is stably positioned within the positioning groove 4, causing the output end of the cylinder 22 to extend. The output end of the cylinder 22 then moves the lifting platform 3, causing it to descend. As the lifting platform 3 descends, the L-shaped plate 6 also descends, which in turn moves the frame 7. The frame 7 then moves the fixing rod 8, which in turn moves the moving block 9, which in turn moves the cleaning frame 10. The cleaning frame 10 then moves the fixed shaft 12, which in turn moves the first roller 13. If the first roller 13 continues to descend after contacting the corrugated guide plate 14, it will move laterally back and forth during the descent. The first roller 13 will then drive the fixed shaft 12 to move, which in turn will drive the cleaning frame 10 to move. The cleaning frame 10 will then move laterally back and forth during the descent or ascent, causing the asphalt inside the cleaning frame 10 to disperse and fully contact the water, thus thoroughly cleaning the asphalt and removing surface dust. The lateral movement of the cleaning frame 10 will also drive the moving block 9 to move, which will compress the spring 11. As the first roller 13 moves along the corrugated guide plate 14, the spring 11 will continuously contract and expand, ensuring thorough cleaning. The washing frame 10 can move horizontally continuously. When the lifting platform 3 descends, the lifting platform 3 also drives the pin 15 to descend. The pin 15 drives the fixing seat 17 to descend, and the fixing seat 17 drives the second roller 18 to descend. The second roller 18 moves along the inclined surface of the L-shaped guide plate 19, allowing the second roller 18 to move closer to the lifting platform 3, which in turn allows the pin 15 to move closer to the L-shaped plate 6. When the second roller 18 moves past the inclined surface of the L-shaped guide plate 19 and reaches the vertical surface of the inner wall of the L-shaped guide plate 19, the pin 15 will insert into the slot 16, thus restricting and fixing the L-shaped plate 6, and thus fixing the washing frame 10. During the horizontal movement of the washing frame 10... The stability of the cleaning frame 10 can be ensured during movement. When the lifting platform 3 moves up and down, it will drive the slider 21 to move along the slide groove 20, ensuring the stability of the lifting platform 3 when moving up and down. After cleaning is completed, the output end of the cylinder 22 is retracted, which allows the lifting platform 3 to move to the top. The staff moves the fixed seat 17 to move the two fixed seats 17 away from each other, which allows the pin 15 to be removed from the slot 16, thereby releasing the restriction on the L-shaped plate 6. The positioning rod 5 can be taken out from the positioning slot 4, and the L-shaped plate 6 can be removed. The cleaning frame 10 can then be removed, and the asphalt inside the cleaning frame 10 that has been cleaned and dusted can be treated. Then, the valve on the water outlet pipe 23 is opened to discharge the wastewater in the cleaning tank 1.

[0021] In summary, this invention enables asphalt to fully contact with the cleaning fluid, more effectively removing surface dust and impurities, improving cleaning results, reducing cleaning time, and increasing overall work efficiency.
