Description

Technical Field

[0001] The utility model relates to the technical field of asphalt recovery, in particular to an asphalt recovery device in waste asphalt mixture. Background Art

[0002] Asphalt is a high-viscosity organic liquid, mainly used in industries such as coatings, plastics, rubber, and road paving. Asphalt will become damaged after long-term use. Since asphalt contains a large amount of other products that are harmful to the human body and the environment, it will cause environmental pollution. Therefore, the damaged waste asphalt needs to be recycled for reuse.

[0003] The currently published patent: CN218532298U discloses a waste asphalt recycling machine. The top of the bottom plate can be sealed by a guide air bag, which is helpful to reduce the situation when the waste asphalt is recycled. Due to the stirring and high temperature inside the asphalt recycling barrel, a large amount of gas and dust is discharged from the top of the asphalt recycling barrel to the outside, thereby causing discomfort to the staff. It will not affect the asphalt entering the interior of the asphalt recycling barrel during use. It is relatively simple and flexible to use.

[0004] Based on the above search, it is found that the above patent has the following problems when in use: the waste asphalt recycling machine can seal the top of the bottom plate through the guide airbag when in use, thereby preventing harmful gases and dust from being discharged to the outside. However, the asphalt recycling machine directly heats and melts the waste asphalt for recycling. Since asphalt contains a large amount of impurities after long-term use, if the waste asphalt is directly melted, the impurities will be melted inside the asphalt, seriously reducing the quality of asphalt recovery. Utility Model Content

[0005] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide an asphalt recovery device in waste asphalt mixture, which can solve the problem that the asphalt recovery machine directly heats and melts the waste asphalt for recovery. Since the asphalt contains a large amount of impurities after long-term use, if the waste asphalt is directly melted, the impurities will be melted inside the asphalt, seriously reducing the quality of asphalt recovery.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an asphalt recovery device in waste asphalt mixture, comprising a melting tank and an asphalt screening device, the asphalt screening device comprising six vibration springs, a screening tank, a conical bulk material plate and a conical screening plate, the six vibration springs are all welded to the top of the melting tank, the screening tank is arranged on the top of the six vibration springs, a feed port is opened on the top of the screening tank, the conical bulk material plate is welded to the inside of the melting tank, the conical screening plate is welded to the bottom of the melting tank, the conical screening plate is welded to the top of the six vibration springs, and a discharge port is opened at the center of the conical screening plate.

[0007] Preferably, a connecting hose is fixedly connected to the bottom of the conical screening disc, and the lower end of the connecting hose extends to the interior of the melting tank.

[0008] Preferably, two motor mounting bases are welded to the surface of the screening tank, and vibration motors are fixedly mounted on the surfaces of the two motor mounting bases.

[0009] Preferably, a sealing round cover is rotatably mounted on the surface of the melting tank, and a heating pipe is fixedly mounted on the bottom of the melting tank.

[0010] Preferably, a waste gas emission pipe is welded on the surface of the melting tank, and a waste gas purifier is fixedly installed on one end of the waste gas emission pipe away from the melting tank.

[0011] Preferably, a circular ring for collecting waste is welded on the surface of the melting tank, and a storage groove is provided on the surface of the circular ring.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) In the asphalt recovery device from waste asphalt mixture, two vibration motors drive the screening tank and the conical screening plate to vibrate and screen on the top of six vibration springs, thereby screening the impurities inside the waste asphalt through the conical screening plate to the outside and falling on the top of the melting tank. The screened asphalt is discharged into the melting tank through the discharge port and the connecting hose for melting treatment, thereby preventing impurities from melting inside the asphalt, ensuring the purity of the waste asphalt recovery, and thus improving the quality of asphalt recovery.

[0014] (2) In the asphalt recovery device in the waste asphalt mixture, the screened asphalt falls to the bottom wall of the melting tank. At this time, the asphalt can be heated and melted through the heating pipe. The exhaust gas purifier absorbs the exhaust gas inside the melting tank through the exhaust gas discharge pipe, thereby preventing the harmful gas generated inside the melting tank from diffusing into the air and causing pollution, thereby improving the working environment of the staff.

[0015] (3) In the asphalt recovery device for waste asphalt mixture, since the top of the melting tank is a conical slope, the impurities fall onto the slope of the top of the melting tank and automatically slide into the interior of the storage tank. The screened impurities are collected through the storage tank, which is convenient for the staff to centrally process the impurities. BRIEF DESCRIPTION OF THE DRAWINGS
