Description

Technical Field

[0001] The utility model relates to the technical field of asphalt production, in particular to an asphalt production emulsification tank. Background Art

[0002] Emulsified asphalt is a liquid asphalt that is generated by the action of asphalt and emulsifier under certain processes, which is oil-in-water or water-in-oil (which one depends on the type of emulsifier). Emulsified asphalt is road asphalt that is usually used at high temperatures. It is diffused into water and liquefied through mechanical stirring and chemical stabilization (emulsification) to become a road construction material with very low viscosity and good fluidity at room temperature. It can be used at room temperature and can also be used with cold and wet stones.

[0003] For example, the patent publication number CN213610767U that has been made public is an emulsified asphalt batching tank for asphalt production. The first rotating wheel is driven to rotate by the rotation of the rotating shaft. The rotating belt and the second rotating wheel can drive the rotating rod to rotate. The rotation of the rotating rod drives the fan-shaped extrusion block to rotate. When the fan-shaped extrusion block rotates, it will squeeze the extrusion plate. Under the action of the push-pull rod, the fixed ring can be driven to move up and down, thereby driving the stirring shaft to move up and down. The stirring shaft can also move up and down while rotating, thereby driving multiple stirring claws to move up and down while rotating, so that the asphalt in the emulsified batching tank can be fully stirred, which greatly saves the stirring time.

[0004] However, the above patent still has the following technical problems: when the emulsification tank is in use, the stirred asphalt will stick to the inner wall of the tank, which is not only difficult to clean but also causes insufficient stirring of the asphalt at the side wall of the tank, resulting in low emulsification efficiency and uneven mixing, which ultimately affects the quality of asphalt production and wastes raw materials. Utility Model Content

[0005] In order to solve the above technical problems, the utility model specifically adopts the following technical solutions.

[0006] An asphalt production emulsification tank is designed, comprising a tank body, a stirring device is arranged in the tank body, a scraping device is arranged in the tank body, the stirring device comprises a stirring shaft rotatably connected to the top of the tank body and a plurality of stirring rods evenly distributed on the stirring shaft, a stirring motor is arranged on the top of the tank body, and the output shaft of the stirring motor is coaxially arranged with the stirring shaft;

[0007] The scraper device comprises a plurality of scrapers slidably arranged with the inner wall of the tank body and a lifting rod connected to the other end of the scraper, a moving block is slidably arranged at the bottom of the tank body, a return spring is connected between one end of the moving block and the inner wall of the tank body, a connecting rod is connected between the lifting rod and the moving block, the two ends of the connecting rod are respectively hinged to the lifting rod and the moving block, and an eccentric wheel in contact with the moving block is connected to the bottom of the stirring rod;

[0008] A feed inlet is arranged at the top of the tank body, and a discharge outlet is arranged at the bottom of the tank body.

[0009] Preferably, a guide rod is provided between the lifting rod and the inner wall of the tank body, and two ends of the guide rod are movably passed through a plurality of scrapers and are respectively connected to the top and bottom of the tank body.

[0010] Preferably, a plurality of turning plates are connected to the other side of the lifting rod.

[0011] Preferably, a plurality of through holes are provided on the turning plate.

[0012] Preferably, the stirring rod is snake-shaped and has different lengths.

[0013] The beneficial effects of the utility model are:

[0014] The utility model can realize uniform stirring of materials at different positions in the tank body by using stirring rods of different lengths. When the stirring shaft drives the stirring rod to stir, the eccentric wheel is driven to rotate along with the stirring shaft, so that the eccentric wheel pushes the moving block to move, squeezes the reset spring, and causes the connecting rod to drive the scraper on the lifting rod to move up and down, thereby scraping off the materials adhered to the inner wall of the tank body, avoiding affecting the stirring and mixing effect, affecting the emulsification quality, and avoiding material waste.
