Description

Technical Field

[0001] This utility model belongs to the field of flue gas treatment technology, specifically, it relates to an asphalt flue gas treatment device. Background Technology

[0002] Asphalt is used in highway paving. Asphalt needs to be heated in a storage tank before paving, which produces pungent asphalt fumes.

[0003] Patent CN206881414U discloses an asphalt fume treatment device for highway construction. It mainly connects to a traction device via a hook and pulley, driving the entire unit to move. The sliding block and dust collection hood are manually moved up and down to achieve the appropriate height and position, ensuring the dust collection hood faces the asphalt fume. After the compressor is turned on, the asphalt fume enters the combustion chamber through the compressor, and the igniter is used for ignition. The combusted gas enters the cyclone separator under the pressure of the combustion chamber. Dust falls into the drawer inside the dust collection box, and the gas is discharged after passing through a filter. However, adjusting the sliding block and dust collection hood causes the connecting pipe to twist. Although the connecting pipe may be a flexible hose, continuous twisting will cause wrinkles in the connecting pipe, reducing the efficiency of asphalt fume adsorption. Furthermore, manually adjusting the height and position of the sliding block and dust collection hood is time-consuming and labor-intensive. Since it removes dust and other particles through the cyclone separator, it cannot cool the combusted fume. High-temperature fume can damage the cyclone separator, and the discharged high-temperature fume can be harmful to human health. Therefore, we propose an asphalt fume treatment device.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] This utility model discloses an asphalt fume treatment device, such as... Figure 1-5 As shown, the system includes a cooling and dust removal tower, a combustion chamber 2, and a compressor 3, which are fixedly installed on a base plate 1 from left to right. Four wheels 4 are installed at the four corners of the bottom of the base plate 1. Hooks 5 are fixedly connected to the front and rear sides of the left end of the base plate 1. The air outlet of the compressor 3 is connected to the air inlet of the combustion chamber 2 via a pipe, and the air outlet of the combustion chamber 2 is connected to the air inlet of the cooling and dust removal tower via a pipe. The air inlet of the compressor 3 is located at the top of the compressor 3 housing. A rotating pipe 6 is rotatably connected to the air inlet of the compressor 3. A sliding tube 7 is slidably connected vertically within the rotating pipe 6. The top of the sliding tube 7 is bent outwards at 90° to form a horizontal tube 8. A movable tube is slidably fitted onto the outside of the horizontal tube 8. 9. The outer end of the moving tube 9 is bent downward at 90° to form a vertical tube 10. The bottom end of the vertical tube 10 is sealed and rotatably connected to the outside of the connecting tube 11. The connecting tube 11 is fixedly installed at the top of the dust collection hood 12. The connecting tube 11 and the dust collection hood 12 are connected internally. A sliding rod 13 is fixedly installed on the left end of the dust collection hood 12. The sliding rod 13 is slidably connected in the sliding sleeve 14. The sliding sleeve 14 is slidably connected to the base plate 1. A first driving mechanism for driving the sliding sleeve 14 to move back and forth is fixedly installed on the front right end of the base plate 1. A second driving mechanism for driving the sliding rod 13 to move up and down is fixedly installed on the side wall of the sliding sleeve 14. The rotating tube 6, the sliding tube 7, the horizontal tube 8, the moving tube 9, and the vertical tube 10 are all rigid tubes.

[0023] The working principle and advantages of this utility model are as follows: The hook 5 is connected to the traction device, driving the entire structure to move. The first drive mechanism is activated, causing the sliding sleeve 14 to move back and forth. The sliding sleeve 14 then moves the sliding rod 13 back and forth, which in turn moves the dust collection hood 12 back and forth. Simultaneously, the second drive mechanism is activated, causing the sliding rod 13 to move up and down, thus moving the dust collection hood 12 up and down. This ensures the dust collection hood 12 reaches a suitable height and position, directly facing the asphalt fumes. After the compressor 3 is turned on, the asphalt fumes enter the combustion chamber 2 through the compressor 3. Ignition is achieved by operating the igniter inside the combustion chamber 2. The combusted gas, under the pressure of the combustion chamber 2, enters the cooling and dust removal tower. The cooling and dust removal tower then purifies the high-temperature combusted gas. This invention achieves cooling and dust removal, allowing the treated gas to be discharged from the cooling and dust removal tower. A first driving mechanism moves the dust collection hood 12 back and forth, while a second driving mechanism moves it up and down, facilitating easy adjustment of the hood's position without manual intervention, saving time and effort. Furthermore, the coordinated operation of the rotating pipe 6, sliding pipe 7, horizontal pipe 8, moving pipe 9, and vertical pipe 10 forms a connected assembly, facilitating the intake of asphalt fumes into the combustion chamber 2. This avoids the need for continuous height and position adjustments using flexible hoses, which can cause wrinkles and improves the efficiency of asphalt fumes extraction. The cooling and dust removal tower further cools and removes dust from the high-temperature fumes, preventing harm to human health from the exhaust.

The transmission screw 18 passes through the slider 17 and is threadedly connected to it. The output shaft of the drive motor 15 is coaxially fixedly connected to the front end of the transmission screw 18. In this embodiment, by starting the drive motor 15, the transmission screw 18 is driven to rotate, thereby driving the slider 17 to move back and forth. The slider 17 drives the slide sleeve 14, the slide rod 13 and the dust collection hood 12 to move back and forth. During the back and forth movement of the dust collection hood 12, the connecting pipe 11 and the vertical pipe 10 rotate relative to each other, the moving pipe 9 and the horizontal pipe 8 slide relative to each other, and the slide pipe 7 drives the rotating pipe 6 to rotate, thereby causing the rotating pipe 6 and the air inlet of the compressor 3 to rotate relative to each other.
