Description

Technical Field

[0001] This utility model relates to the field of asphalt concrete processing technology, specifically to a dust treatment device for processing asphalt concrete. Background Technology

[0002] Asphalt concrete is a commonly used type of concrete. It is a mixture made by artificially selecting mineral materials with a certain gradation, such as crushed stone or crushed gravel, stone chips or sand, and mineral powder, and mixing them with a certain proportion of road asphalt materials under strict control conditions. When asphalt concrete is fed, a large amount of dust is generated. The dust emitted from the feed port into the air can easily pollute the air and cause environmental pollution. Therefore, dust control equipment is required.

[0003] Existing dust control equipment is usually directly connected to the mixing tank, using suction to extract dust from inside the mixing tank and collecting it through a collection box. However, the mixing tank continuously generates dust while mixing the materials. Before water is added, the dust needs to be continuously collected by the dust control equipment to prevent dust from being discharged from the inlet, resulting in significant energy loss. However, when treating the dust, the water supply pipe replenishes water to the treatment tank while simultaneously treating the dust inside, and then drains the water through the outlet pipe. This repeated replenishment and drainage for dust suppression wastes a large amount of clean water, leading to water resource waste.

[0004] To address the aforementioned technical problems, this application proposes a dust treatment device for processing asphalt concrete. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] As attached Figure 1Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, a dust treatment device for processing asphalt concrete includes a feeding dust collector 1 and a mixing tank 2. The feeding dust collector 1 is installed on the upper side of the mixing tank 2. A feeding trough 3 is installed on the top of the feeding dust collector 1. A discharge port 26 communicating with the mixing tank 2 is provided at the bottom of the feeding dust collector 1. An inclined feeding screen 4 and a collecting inclined plate 5 are installed inside the feeding dust collector 1. The inclined feeding screen 4 and the collecting inclined plate 5 are located on both sides of the feeding trough 3 and the discharge port 26, respectively. The mixture enters the inner side of the feeding dust collector 1 through the feeding trough 3 and is fed towards the discharge port 26 along the inclined feeding screen 4 and the collecting inclined plate 5. The mixture is then sent into the mixing tank 2 through the discharge port 26.

[0029] The bottom of the feeding dust collector 1 is slidably fitted with a baffle 23 to close the discharge port 26. A moving assembly is installed at the bottom of the feeding dust collector 1 to drive the baffle 23 to move laterally. The moving assembly includes an electric telescopic rod 22. A mounting groove 21 is provided at the bottom of the feeding dust collector 1, located below the collecting inclined plate 5. The electric telescopic rod 22 is fixedly installed inside the mounting groove 21. A connecting frame 24 is installed at the extended end of the electric telescopic rod 22. The bottom of the mounting groove 21 is provided with a slide rail 25 through which the connecting frame 24 slides. The lower side of baffle 24 is connected to baffle 23. The electric telescopic rod 22 is controlled by an external control switch. The electric telescopic rod 22 extends and retracts, causing baffle 23 to move laterally at the bottom of the feeding dust collector 1, thereby closing and opening the discharge port 26. The upper side of baffle 23 is in contact with the bottom of the feeding dust collector 1, and a rubber pad is provided on the upper side of baffle 23. When closing the discharge port 26, it prevents dust from entering the interior of the feeding dust collector 1. The width of baffle 23 can simultaneously close the slide 25 and the discharge port 26. Therefore, dust will not enter the interior of the mounting groove 21.

[0030] As attached Figure 1 Appendix Figure 3 and attached Figure 5 As shown, a blower 7 is installed on the side wall of the feeding dust collection box 1. The blower 7 is located on the lower side of the middle part of the inclined feeding screen plate 4. When the mixture is fed on the upper side of the inclined feeding screen plate 4, the blower 7 blows the dust in the mixture out.

[0031] A dust-suppressing water tank 9 is installed on the top of the feeding dust collector 1. A dust guiding component is connected between the upper side of the collecting inclined plate 5 and the dust-suppressing water tank 9. The dust guiding component includes a dust collection frame 6, which is installed on the upper side of the collecting inclined plate 5. The side of the dust collection frame 6 near the inclined feeding screen 4 is a perforated plate. A dust discharge pipe 8 is connected to the dust collection frame 6. The other end of the dust discharge pipe 8 is connected to the dust-suppressing water tank 9. An exhaust fan 20 is installed on the upper side of the dust-suppressing water tank 9. The exhaust fan 20 draws out the air from the dust-suppressing water tank 9, creating suction in the dust-suppressing water tank 9 and the dust discharge pipe 8. The dust floating in the feeding dust collector 1 is sucked into the dust collection frame 6 and collected by the dust discharge pipe 8 and sent to the interior of the dust-suppressing water tank 9.

[0032] As attached Figure 5 and attached Figure 6 As shown, a partition 17 is installed inside the dust suppression water tank 9. A dust suppression assembly is installed on the top of the dust suppression water tank 9, between the partition 17 and the port of the dust discharge pipe 8. The dust suppression assembly includes a connecting pipe 10 and multiple sets of dust suppression pipes 11. One end of the connecting pipe 10 is connected to a water supply pipe 16. Water is supplied to the connecting pipe 10 through an external water supply device connected to the water supply pipe 16. The multiple sets of dust suppression pipes 11 are respectively connected to the connecting pipe 10. The water in the connecting pipe 10 is delivered to the inside of the multiple sets of dust suppression pipes 11. Multiple sets of dust-collecting pipes 11 are fixedly installed on the top of the dust-collecting water tank 9. Multiple sets of spray heads 12 and 23 are respectively installed on the lower side of the connecting pipe 10 and the multiple sets of dust-collecting pipes 11. Water mist is sprayed out through the multiple sets of spray heads 12 and 23 to form a multi-faceted water mist wall, which surrounds the dust discharge end of the dust discharge pipe 8 to achieve a better dust-collecting effect. A dust filter plate 18 is installed on the upper part of the partition 17. The dust filter plate 18 prevents the dust that is missed from being discharged from the dust-collecting water tank 9 with the exhaust fan 20.

[0033] A filter screen 19 is installed at the lower part of the partition 17 to block large particulate impurities in the water at the bottom of the dust settling water tank 9. One end of the connecting pipe 10 is connected to a water guide pipe 15. The bottom of the dust settling water tank 9 is connected to a pump body 14. The water inlet of the pump body 14 is located on the side of the partition 17 away from the dust discharge pipe 8. The water guide pipe 15 is connected to the drain end of the pump body 14. Water without large particulate impurities is sent to the connecting pipe 10 for reuse through the pump body 14 and the water guide pipe 15, thereby improving the utilization rate of water resources. When there is a lot of impurities accumulated at the bottom of the dust settling water tank 9, the baffle on the outside of the cleaning port on the side wall of the dust settling water tank 9 is opened to clean the impurities through the cleaning port.
