Description

Technical Field

[0001] The utility model relates to an asphalt stirring device, in particular to an asphalt stirring device for producing modified asphalt waterproofing coiled material, belonging to the technical field of asphalt waterproofing coiled material production. Background Art

[0002] The asphalt used in the production of modified asphalt waterproofing membranes is a modified asphalt material, which is usually modified by mixing original asphalt with specific polymers. In the production process of modified asphalt waterproofing membranes, the original asphalt used is mainly petroleum asphalt, which is a substance obtained by processing and distillation of natural asphalt rock. Petroleum asphalt is a hydrophobic organic matter with colloidal viscosity and good adhesion and waterproof properties. However, original asphalt becomes brittle at low temperatures and becomes soft and fluid at high temperatures, which limits its application in waterproofing membranes. Therefore, in the production of modified asphalt waterproofing membranes, in order to enhance the performance of asphalt, improve its high and low temperature resistance, and improve bonding strength and flexibility, specific polymers are often mixed and modified with original asphalt. At this time, an asphalt mixing device for the production of modified asphalt waterproofing membranes is needed.

[0003] Among them, an asphalt stirring device for the production of modified asphalt waterproofing membrane with application number "CN202322107101.6" comprises: a stirring tank and a motor, the motor is fixedly connected to the top surface of the stirring tank, and the output end of the motor passes through the top surface of the stirring tank and extends into the stirring tank, a rotating shaft is fixedly connected to the output end of the motor, a first rotating groove is provided on the circumference of the upper half of the rotating shaft, a first stirring roller is rotatably connected to the first rotating groove, a fixed plate is fixedly connected to the top surface of the first stirring roller, and the fixed plate is sleeved on the first rotating groove; a transmission assembly, the transmission assembly is located in the stirring tank. The utility model solves the problem that the stirring mode of the stirring device is too single, which causes the stirring device to consume a lot of time when stirring the modified asphalt for the production of waterproofing membrane, thereby reducing the work efficiency, and solves the problem that part of the asphalt sticks to the inner wall and the bottom surface of the inner cavity of the stirring device and cannot be taken out, resulting in a waste of resources.

[0004] However, the above-mentioned type of asphalt mixing device for the production of modified asphalt waterproofing membranes still has certain deficiencies when in use. Since the modified asphalt material used in the production of waterproofing membranes has a certain viscosity, when the inner wall of the device is cleaned by two scrapers for a long time, material residues will also adhere to the scrapers. Since the one-piece closed mixing tank is not provided with any inspection port or inspection door, it is impossible to clean its internal components after long-term use, and it is also impossible to repair or replace its internal components separately. When a single or partial component inside is damaged and the entire device cannot work, the device can only be replaced as a whole, which is very wasteful and inconvenient to clean, repair or replace the various components inside the device more conveniently.
