Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of stirring devices, in particular to a uniform stirring device for asphalt modification production. BACKGROUND

[0002] Asphalt is a black-brown complex mixture composed of hydrocarbons and non-metallic derivatives of different molecular weights, which is a high-viscosity organic liquid, mostly in the form of liquid or semi-solid petroleum, with a black surface, and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is an organic cementing material for waterproofing, moisture-proofing and corrosion-proofing, which can be mainly divided into coal tar pitch, petroleum asphalt and natural asphalt, and is mainly used in industries such as coatings, plastics and rubber, and for paving roads, etc.

[0003] In the prior art, the asphalt stirring device for modified asphalt waterproof coiled material production with publication number CN219631088U solves the problem that the stirring mode of the stirring device is too single, which leads to the consumption of a large amount of time when the stirring device is stirring the modified asphalt for waterproof coiled material production, and reduces the work efficiency, and solves the problem that part of the asphalt will stick to the inner wall and the bottom surface of the inner cavity of the stirring device and cannot be taken out, causing resource waste, but there are still the following problems: The above-mentioned stirring device, when in use, is stirred by two second stirring rollers and a first stirring roller. However, the device realizes stirring operation by cooperation of the two second stirring rollers and the first stirring roller, but smoke and dust will be generated during the stirring process of the modified asphalt (especially in a high-temperature environment), and the device does not have any smoke and dust purification or treatment structure, so that the smoke and dust is directly discharged to the external environment, polluting the surrounding ecology and air quality. The modified asphalt stirring needs to heat the tank body to ensure the fluidity and mixing effect of the material. The device adopts a traditional jacket type heat exchange heating method, which has a small heat transfer area and low heating efficiency, and it is difficult to quickly make the material in the tank reach a uniform temperature.
