AI Technical Summary

Technical Problem

In the cleaning process of existing asphalt raw material mixing devices, it is difficult to automatically clean the asphalt raw material residue on the outer wall of the mixing rod, resulting in tedious and inefficient manual cleaning.

Method used

Design a mixing device including a rotating shaft, scraper, mixing rod and sliding assembly. The rotating shaft drives the scraper to slide along the inner wall of the tank. Combined with the lifting cylinder, the scraper is driven to approach the mixing rod. The outer wall of the mixing rod is automatically cleaned with cleaning fluid, and the asphalt raw material in the gaps is rinsed through the water spray nozzle.

Benefits of technology

It achieves automatic cleaning of the outer wall of the stirring rod, reducing the trouble and time of manual cleaning, improving cleaning efficiency, and ensuring high-efficiency cleaning quality inside the tank.

Abstract

The utility model discloses a raw material proportioning and mixing device for asphalt processing. Comprising a cylindrical raw material mixing tank, a rotating shaft vertically and rotatably arranged at the center position in the raw material mixing tank, a worm and gear speed reducing motor for driving the rotating shaft to rotate, and three scraping plates vertically and uniformly surrounding the rotating shaft, wherein one side of each scraping plate can be in parallel contact with the inner wall of the raw material mixing tank; the stirring rods horizontally penetrate through the scraping plate, one ends of the stirring rods are vertically and fixedly connected with the side wall of the rotating shaft, the sliding assembly drives the scraping plate to slide along the stirring rods penetrating through the scraping plate and is close to or far away from the rotating shaft in parallel, and the worm and gear speed reducing motor is fixed to the top of the raw material mixing tank; and the output end of a worm and gear speed reducing motor is fixedly inserted. The stirring tank has the advantage of automatically cleaning the inner wall of the tank body and the outer wall of the stirring rod.
