Technical Field
[0001] This utility model relates to the field of asphalt dissolution technology, and in particular to an asphalt dissolution furnace. Background Technology
[0002] Asphalt is a product of crude oil processing. Traditional asphalt production equipment suffers from difficulties in asphalt separation due to the single dissolution step, which affects the asphalt separation rate and the subsequent processing of asphalt products. Therefore, there is a need for a more complete dissolution device for asphalt production. Current asphalt dissolution devices generally dissolve asphalt directly, with a large amount of asphalt being poured directly into the dissolution device for heating. The heating area is mainly the inner wall of the device, which may lead to uneven heating of the asphalt and may affect the dissolution efficiency of the asphalt.
[0003] To address the aforementioned problems, existing patent (CN219772045U) discloses a dissolving device for asphalt production. This device includes a housing, and further comprises: a first baffle symmetrically slidably disposed within the housing; a second baffle symmetrically slidably disposed within the housing, with the second baffle positioned below the first baffle; a cone fixedly disposed at the lower end of the housing; a heating cylinder equidistantly fixedly disposed within the housing, positioned between the first and second baffles; a rotating shaft rotatably disposed within the heating cylinder; a scraper fixedly connected to the rotating shaft; and a second motor fixedly disposed on the housing, with the output end of the second motor fixed to the rotating shaft. This invention effectively prevents harmful gases from entering the air, effectively increases the heating area of the asphalt, and thus effectively improves the asphalt dissolving rate.
[0004] However, the aforementioned existing technologies do not effectively treat the harmful gases generated, and secondary operations may lead to the leakage of harmful gases, causing environmental pollution. Utility Model Content

[0008] The cleaning component further includes a drive gear and a fixed base. One end of the drive gear is fixedly connected to the output end of the motor and is located inside the fixed frame. The fixed base is rotatably connected to the other end of the drive gear and is located on the side of the drive gear away from the motor.
[0009] The cleaning component further includes a gear ring, a limiting ring, and an inner ring layer. The gear ring meshes with the driving gear and is located outside the driving gear. The limiting ring is fixedly connected to the gear ring and is located inside the gear ring. The inner ring layer is fixedly connected to the limiting ring and is located inside the limiting ring.
[0010] The cleaning component further includes a scraper, a central rod, and a filter plate. The scraper is rotatably connected to the melting furnace body and is located below the inner ring layer.

The melting furnace body 101, as described in prior art CN219772045U, is used for dispersing, heating, dissolving, and filtering asphalt, and therefore will not be elaborated upon. After the asphalt enters the melting furnace body 101, it closes the closing cover 104. The sealing ring 105 enhances the sealing effect of the closing cover 104. When the asphalt is being dissolved, the generated harmful gases enter the discharge pipe 106. The purifier 107 purifies the harmful gases before discharging them. The purifier 107 is equipped with a primary activated carbon adsorption layer, a high-efficiency activated carbon fiber adsorption layer, and a molecular sieve adsorption layer, so that the harmful gases are adsorbed and purified sequentially through the primary activated carbon adsorption layer, the high-efficiency activated carbon fiber adsorption layer, and the molecular sieve adsorption layer. The dissolved asphalt is filtered and discharged from the discharge pipe 103. This method can effectively solve the problem of environmental pollution caused by the leakage of harmful gases.
[0022] The cleaning component includes a fixing frame 108 and a motor 109. The fixing frame 108 is fixedly connected to the melting furnace body 101 and is located on the outside of the melting furnace body 101.

The inner ring layer 114 drives the scraper 115 to rotate on the surface of the filter plate 117. The central rod 116 ensures the stable rotation of the scraper 115. The scraper 115 scrapes off the asphalt remaining inside the melting furnace body 101 and on the surface of the filter plate 117.
[0026] Using an asphalt melting furnace according to this embodiment, by setting the feed pipe 102, the discharge pipe 103, and the filter assembly, in specific use, asphalt enters the melting furnace body 101 through the feed pipe 102.
