Description

Technical Field

[0001] The utility model specifically relates to the technical field of asphalt unloading, in particular to a unloading device for asphalt processing. Background Art

[0002] A large amount of hot air is generated during the processing of asphalt, which makes the temperature of the asphalt higher and ensures the fluidity of the asphalt. However, when the asphalt is unloaded, a large amount of heat is separated from the asphalt. The components of the asphalt hot air mainly include tar, and also contain a variety of carcinogens that are harmful to the human body. Therefore, during the unloading of asphalt, a large amount of hot air mixes with the air, causing damage to the working environment. After the harmful substances in the air are inhaled by the human body, it will seriously affect human health.

[0003] At present, when traditional asphalt is unloaded, water fans or water curtains are generally used to achieve the effect of dust removal and cooling the heat generated by asphalt unloading. However, when processing in this way, only larger substances in the heat can be separated, and smaller substances cannot be effectively separated. In this way, effective substances will still spread through the air. In addition, the traditional processing method requires a large amount of water resources, and the processing effect is not ideal.

[0004] After searching, Chinese patent publication No. CN201920792974.6 discloses an asphalt fume and dust treatment device for an asphalt mixing station; the asphalt fume and dust treatment device for the asphalt mixing station includes a fume outlet of the drying drum connected to the air inlet of the dust collector; the exhaust gas collecting device is arranged at the discharge port of the mixing pot and the finished product silo, and the exhaust gas collecting device is connected to the asphalt fume output device; the asphalt fume output device is connected to a port of the burner air inlet tee pipe; after the asphalt fume is burned by the burner, the exhaust gas enters the dust collector, and after being purified by the dust collector, the exhaust gas is discharged after meeting the environmental protection requirements.

[0005] The device in the above patent discharges asphalt through the finished product silo into the receiving channel, which cannot effectively ensure the amount of smoke inside the receiving channel. When the finished product silo continues to discharge into the receiving channel, a large amount of smoke in the asphalt cannot be effectively and timely collected and processed by the second exhaust gas collection ring pipe, which will cause the smoke to leak from the inside of the receiving channel, causing pollution to the surrounding working environment.

[0006] In view of the above situation, we provide a unloading device for asphalt processing. In this device, the two driving gears are driven to rotate by a reducer to realize the opening or closing between the flap and the discharge port. In this way, the volume of the asphalt unloading can be effectively controlled during unloading, ensuring that the smoke generated during unloading can be adsorbed in time, and effectively preventing the smoke generated during unloading from leaking to positions outside the frame. When adsorbing the smoke, the negative pressure machine transmits the smoke to the suction duct through the adsorption shell, and the end of the suction duct is connected to the activated carbon adsorption box through a conveying pipe to achieve effective adsorption of harmful substances in the smoke. The gas adsorbed by the induced draft fan is extracted into the gas purification box, and the gas after passing through the gas purification box meets the emission requirements.
