Description

Technical Field

[0001] This utility model relates to the field of dust suppression technology in asphalt concrete mixing, and in particular to a dust suppression device for the asphalt concrete mixing process. Background Technology

[0002] Dust suppression technologies in asphalt concrete mixing processes mainly include the following: Baghouse dust collectors: Baghouse dust collectors are one of the most widely used dry dust collection devices, using filter bags made of woven fabric to capture solid particles in the air. For asphalt mixing plants, it is recommended to use high-efficiency filter bags with waterproof and oil-proof coatings and equip them with an automatic pulse cleaning system to ensure continuous and stable filtration effects. Sintered plastic plate dust collectors: For applications requiring the handling of high-humidity, highly viscous dust, sintered plastic plate dust collectors are a better choice. They have better hydrophobicity and corrosion resistance, effectively preventing the adhesion of moisture and oil while maintaining high collection efficiency. Wet scrubbers: In certain specific situations, such as when there is a risk of flammability and explosion or when the dust contains chemicals, wet scrubbers can be selected. These devices absorb fine particles in the airflow through spray towers or other forms of water films and dissolve them in water before discharging.

[0003] An existing dust suppression device for asphalt concrete mixing processes uses fixed filters to adsorb and filter most of the dust generated during concrete mixing. However, after the device has been working for a long time, dust tends to adhere to the filters, affecting the device's adsorption and filtration efficiency. This also makes it inconvenient for workers to easily install, disassemble, and clean the filters after prolonged use. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a dust suppression device for the asphalt concrete mixing process.

[0005] This utility model is achieved by the following technical solution: a dust suppression device for asphalt concrete mixing process, including a flange, an air inlet pipe fixedly connected to the inner wall of the flange, a support frame fixedly connected to the bottom of the air inlet pipe, a purification box threadedly connected to the rear end of the support frame, and an exhaust pipe threadedly connected to the rear end of the purification box.

[0006] A support plate is fixedly connected to the right end of the exhaust pipe, a drive motor is fixedly connected to the top of the support plate, and an exhaust fan blade is fixedly connected to the output end of the drive motor. A filter screen is inserted inside the purification box, and a limit bar is snapped onto the top of the filter screen. An installation frame is fixedly connected to the front and rear ends of the purification box, and a rotating frame is fixedly connected to the left and right ends of the purification box. A limit block is rotatably connected to the surface of the rotating frame.

[0007] Through the above technical solution, the right end of the exhaust pipe is connected to a support plate. The drive motor on the support plate drives the exhaust fan blades to rotate. During the dust suppression process, the rotation of the exhaust fan blades provides power for the flow of dust-laden gas within the equipment. Compared to natural exhaust, this motor-driven exhaust method can increase the gas flow velocity, allowing the dust-laden gas to pass through the purification chamber for purification more quickly, thereby improving the efficiency of dust suppression.

[0008] As a further improvement to the above solution, the number of the bearing support plates is set to two, and the two bearing support plates are symmetrically distributed front and back with the exhaust pipe as the center, and the exhaust fan blades are located inside the exhaust pipe.

[0009] Through the above technical solution, the dust-laden gas generated by asphalt concrete mixing first enters the air inlet pipe, then enters the purification box for purification treatment, and finally is discharged through the exhaust pipe, making the dust treatment process continuous, effectively avoiding problems such as dust leakage, and ensuring the dust suppression effect.

[0010] As a further improvement to the above solution, the number of filter screens is set to several, and the several filter screens are equidistantly distributed around the purification box, with the filter screens located at the rear end of the air inlet pipe.

[0011] As a further improvement to the above solution, the filter screen is located on the front of the exhaust pipe, and the number of the limiting crossbars is set to two, with the two limiting crossbars symmetrically distributed on the left and right sides with the filter screen as the center.

[0012] As a further improvement to the above solution, the limiting crossbar is located at the top of the purification box, and the number of the mounting frames is set to four, with each pair forming a group, and the four mounting frames are symmetrically distributed front and back around the purification box.

[0013] As a further improvement to the above solution, a limit crossbar is inserted inside the mounting frame, and the number of rotating frames is set to two.

[0014] As a further improvement to the above solution, the bottom of the limiting support block contacts the top surface of the limiting crossbar, and the number of the limiting support blocks is set to four, with each pair forming a group, and the four limiting support blocks are symmetrically distributed front and back around the purification box.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention allows the limiting block to be removed from the surface of the limiting crossbar when it rotates on the surface of the rotating frame. The limiting crossbar can then be pulled to disassemble the frame and the top of the filter screen. This allows for convenient installation and removal of the filter screen, which has been working for a long time and has accumulated dust, from inside the purification chamber. This also makes it easier for staff to clean the filter screen and improves the efficiency of dust suppression in the equipment.

[0017] This invention features two symmetrically distributed limiting crossbars that are snapped onto the top of the filter screen, with the limiting crossbars located at the top of the purification chamber. Simultaneously, the limiting crossbars are inserted into the mounting frame, and the bottom of the limiting support block rotatably connected to the surface of the rotating frame contacts the top surface of the limiting crossbars. This complex limiting and fixing structure ensures the stability of the filter screen within the purification chamber. During equipment operation, especially under the impact force generated by gas flow, the stable filter screen maintains its filtering function without shifting or shaking, thus guaranteeing the normal operation of the purification chamber.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-5The dust suppression device for asphalt concrete mixing process in this embodiment includes a flange 1, an air inlet pipe 2 fixedly connected to the inner wall of the flange 1, a support frame 3 fixedly connected to the bottom of the air inlet pipe 2, a purification box 4 threadedly connected to the rear end of the support frame 3, and an exhaust pipe 5 threadedly connected to the rear end of the purification box 4.

[0028] A support plate 6 is fixedly connected to the right end of the exhaust pipe 5. A drive motor 7 is fixedly connected to the top of the support plate 6. An exhaust fan blade 8 is fixedly connected to the output end of the drive motor 7. A filter screen 9 is inserted inside the purification box 4. A limiting crossbar 10 is snapped onto the top of the filter screen 9. An installation frame 11 is fixedly connected to the front and rear ends of the purification box 4. A rotating frame 12 is fixedly connected to the left and right ends of the purification box 4. A limiting block 13 is rotatably connected to the surface of the rotating frame 12. When the limiting block 13 is rotated on the surface of the rotating frame 12, the limiting block 13 can be removed from the surface of the limiting crossbar 10. Then, the limiting crossbar 10 can be pulled to disassemble from the top of the installation frame 11 and the filter screen 9. The filter screen 9, which has been working for a long time and has absorbed dust, can be easily installed and removed from the inside of the purification box 4, making it easy for staff to clean the filter screen 9 and improving the efficiency of the equipment in suppressing dust.

[0029] The right end of the exhaust pipe 5 is connected to the support plate 6. The drive motor 7 on the support plate 6 drives the exhaust fan blades 8 to rotate. During the dust suppression process, the rotation of the exhaust fan blades 8 provides power for the flow of dust-laden gas within the equipment. Compared to natural exhaust, this motor-driven exhaust method can increase the gas flow speed, allowing the dust-laden gas to pass through the purification box 4 for purification more quickly, thereby improving the efficiency of dust suppression.

[0030] The number of support plates 6 is set to two, and the two support plates 6 are symmetrically distributed front and back with the exhaust pipe 5 as the center. The exhaust fan blades 8 are located inside the exhaust pipe 5.

[0031] The dust-laden gas generated during asphalt concrete mixing first enters the air inlet pipe 2, then enters the purification box 4 for purification treatment, and finally is discharged through the exhaust pipe 5. This ensures the continuity of the dust treatment process, effectively avoids dust leakage and other problems, and guarantees the dust suppression effect.

[0032] The number of filter screens 9 is set to several, and the filter screens 9 are distributed at equal intervals around the purification box 4. The filter screens 9 are located at the rear end of the air inlet pipe 2.

[0033] The filter screen 9 is located on the front of the exhaust pipe 5. There are two limiting crossbars 10, which are symmetrically distributed on the left and right sides with the filter screen 9 as the center. The top of the filter screen 9 is clamped with two symmetrically distributed limiting crossbars 10, and the limiting crossbars 10 are located on the top of the purification box 4. At the same time, the limiting crossbars 10 are inserted into the mounting frame 11. The bottom of the limiting support block 13 rotatably connected to the surface of the rotating frame 12 contacts the top surface of the limiting crossbars 10. This complex limiting and fixing structure ensures the stability of the filter screen 9 in the purification box 4. During the operation of the equipment, especially under the impact force generated by the gas flow, the stable filter screen 9 can always maintain its filtering function without displacement or shaking, thus ensuring the normal operation of the purification box 4.

[0034] The limiting crossbar 10 is located at the top of the purification box 4. The number of mounting frames 11 is set to four, and each pair is a group of four. The four mounting frames 11 are symmetrically distributed front and back with the purification box 4 as the center.

[0035] The mounting frame 11 has internally inserted limit crossbars 10, and the number of rotating frames 12 is set to two.

[0036] The bottom of the limiting support block 13 contacts the top surface of the limiting crossbar 10. The number of limiting support blocks 13 is set to four, and each pair is a group. The four limiting support blocks 13 are symmetrically distributed back and forth with the purification box 4 as the center.

[0037] The implementation principle of the dust suppression device for asphalt concrete mixing process in this embodiment is as follows: When the limiting support block 13 rotates on the surface of the rotating frame 12, the limiting support block 13 can be removed from the surface of the limiting crossbar 10. Then, the limiting crossbar 10 can be pulled to disassemble from the top of the mounting frame 11 and the filter screen 9. This allows for convenient installation and removal of the filter screen 9, which has been working for a long time and adsorbing dust, from inside the purification box 4. This facilitates easy cleaning of the filter screen 9 by the staff, improving the efficiency of dust suppression. Two symmetrically distributed limiting crossbars 10 are snapped onto the top of the plate 9, and the limiting crossbars 10 are located at the top of the purification box 4. At the same time, the limiting crossbars 10 are inserted into the mounting frame 11. The bottom of the limiting support block 13, which is rotatably connected to the surface of the rotating frame 12, contacts the top surface of the limiting crossbars 10. This complex limiting and fixing structure ensures the stability of the filter plate 9 in the purification box 4. During the operation of the equipment, especially under the impact force generated by the gas flow, the stable filter plate 9 can always maintain its filtering function without displacement or shaking, thus ensuring the normal operation of the purification box 4.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
