Description

Technical Field

[0001] This utility model relates to the field of asphalt recycling technology, and in particular to a device for recycling asphalt waste in asphalt production. Background Technology

[0002] Asphalt is a dark brown, complex mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid, often existing in liquid or semi-solid petroleum form, with a black surface, and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementing material. Asphalt can be mainly classified into three types: coal tar pitch, petroleum asphalt, and natural asphalt. Coal tar pitch is a byproduct of coking. Petroleum asphalt is the residue after crude oil distillation. Natural asphalt is stored underground, sometimes forming mineral layers or accumulating on the earth's surface. Asphalt is mainly used in the coatings, plastics, and rubber industries, as well as in road paving.

[0003] Existing asphalt waste recycling devices lack dust removal equipment, causing the large amount of dust mixed in with the asphalt waste to easily spread and impact the external environment. Furthermore, these devices lack screening equipment, making it impossible to effectively remove the large amount of dust mixed in with the asphalt waste. For example, Chinese patent disclosure "An Asphalt Road Waste Recycling Device" (application number: CN202220471619.0) includes: a device body, a crushing motor fixed to the surface of the device body, a feed inlet fixed to the upper end of the device body, and an anti-splash structure installed inside the feed inlet. Although this device can crush and recycle asphalt, it lacks dust removal equipment, causing the large amount of dust mixed in with the asphalt waste to easily spread and impact the external environment. Moreover, the lack of screening equipment further limits its applicability. Utility Model Content

The upper surface of the base frame 1 is fixedly connected to a dust suppression mechanism, which includes: a fixed frame 8, a water tank 9 fixedly connected to the upper surface of the fixed frame 8, a water pump 10 fixedly connected to the upper surface of the fixed frame 8, a water pipe 11 fixedly connected to the output end of the water pump 10, and an atomizing nozzle 12 fixedly connected to one end of the water pipe 11. This allows the dust on the asphalt waste to be absorbed by the atomized water, preventing the dust mixed in with the asphalt waste from being blown out of the shell, thus achieving a better dust removal effect. The atomizing nozzle 12 is fixedly connected to the lower surface of the fixed frame 8. Multiple sets of atomizing nozzles 12 are provided and symmetrically arranged to facilitate the atomization and dust suppression of dust on the asphalt waste.

[0026] A vibrating screening mechanism is fixedly connected to the upper surface of the base frame 1. The vibrating screening mechanism includes a vibrating device 13, a vibrating plate 15 fixedly connected to the inner side of the vibrating device 13, and the inner surface of the vibrating plate 15 is inclined. A vibrating motor 14 is fixedly connected to the lower surface of the vibrating plate 15 by screws to facilitate the screening of asphalt waste.

[0027] Working principle: When asphalt waste needs to be recycled and reused, workers bring a large amount of asphalt waste to the work site where the asphalt waste recycling device is located. The workers then pour the waste into the crushing box 2. The servo motor 3 is activated, causing the first gear 4 to mesh with the second gear 5, which in turn drives the crushing roller 6 to crush the asphalt waste. During crushing, a large amount of dust is generated. The water pump 10 is then activated, drawing water from the water tank 9 through the water pipe 11. This water is then used to suppress the dust on the asphalt waste through the atomizing nozzle 12. Dust is adsorbed by atomized water, preventing dust mixed in with asphalt waste from being blown out of the shell, thus achieving a better dust removal effect. Secondly, the crushed asphalt waste enters the vibrating screening mechanism through the funnel 7. The vibration motor 14 is started, causing the asphalt waste on the vibrating plate 15 to vibrate. The crushed asphalt waste is screened through the first screen plate 16, the second screen plate 17 and the third screen plate 18. The dust residue remaining on the asphalt waste that falls onto the screen can be removed by vibration, and large pieces of asphalt that have not been crushed into finer asphalt slag can be screened out for secondary crushing, achieving a better screening effect.
