Description

Technical Field

[0001] The utility model relates to the technical field of asphalt mixing equipment, in particular to a modified asphalt mixing device with a cleaning function. Background Art

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is in liquid state, black on the surface, and soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosive organic gelling material, mainly used to make coatings, plastics and rubber, and paving roads. Asphalt mixer is a machine used to mix asphalt. Generally, due to the high viscosity of asphalt, frame-type mixing shaft is mainly used.

[0003] Asphalt has high viscosity and is easily adhered to the surface of the stirring rod or the stirring kettle, which is difficult to clean. The automatic asphalt mixing equipment in the prior art is generally an integrated equipment, in which the stirring rod, the motor driving the stirring rod and the reactor are fixed together by bolts. The process of removing the stirring rod to clean the stirring rod and the reactor separately is very troublesome.

[0004] For example, Chinese patent publication No. CN214438414U discloses an asphalt mixing device that is easy to clean. The asphalt mixing device is installed on a lifting platform through a stirring rod and a first motor for stirring, and is designed separately from a stirring kettle. Firstly, the stirring rod can be cleaned after the lifting platform rises, and further, the stirring kettle can be rotated in a vertical direction after the pin is removed, which is convenient for unloading on the one hand and for flushing the inside of the stirring kettle on the other hand.

[0005] The existing technology has the following problems:

[0006] However, asphalt has great viscosity, it is easy to stick to the inner wall of the mixing tank during the mixing process, and it is difficult to scrape it off by just flushing after it sticks. The scraping effect of linear scraping is also limited. Therefore, a scraping method with better scraping effect is needed to complete the scraping operation of the mixing tank during the mixing process. Utility Model Content

[0007] The utility model provides a modified asphalt stirring device with a cleaning function to solve the problems raised in the above background technology.

[0008] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0027] See also Figure 1-Figure 4 , the utility model provides a technical solution:
