A stirring blade of a stirring mechanism for asphalt stone mixing and stirring heating tank

Abstract

The invention relates to a stirring blade of a stirring mechanism of an asphalt stone mixing stirring heating kettle. The stirring blade comprises a pedestal, a stirring arm, and a blade part. The stirring blade is provided with a rotating axis; the stirring arm is provided with a center line; the center line is vertical to the rotating axis; an included angle alpha is formed between a projection of the blade part on a plane vertical to the center line and the rotating axis, and 0 DEG<alpha<90 DEG; and the stirring arm and / or the blade part is provided with a plurality of stirring protruding teeth. The stirring blade is simple in structure, and is reasonable in design; a three-dimensional spiral structure is formed by a plurality of the stirring blades; the stirring blade is convenient for uniform stirring, and is capable of cutting, smashing and delivering materials; when mixed materials are stirred, the mixed materials are pressed and extruded by the stirring blade, so that stirring is more uniform; the stirring protruding teeth are capable of rotating, and realizing fine stirring, cutting and smashing of mixed materials, so that stirring is more uniform; in addition, the design of the stirring protruding teeth is beneficial for local stirring, and is capable of avoiding local hardening or nonuniformity.

Description

technical field [0001] The invention relates to a stirring blade of a stirring mechanism of an asphalt stone material mixing and stirring heating tank. Background technique [0002] Asphalt concrete is artificially selected with a certain grade of mineral materials (crushed stone or crushed gravel, stone chips or sand, mineral powder, etc.) and a certain proportion of road asphalt materials, and mixed under strictly controlled conditions. of the mixture. The traditional preparation process of asphalt concrete generally first heats and melts the asphalt glue and dries and heats the crushed stone, and then puts the hot asphalt and the dried and heated crushed stone into the mixer for mixing. [0003] In the prior art, the mixer generally includes a mixing mechanism and a mixing chamber for accommodating hot asphalt and dried heated crushed stones. The mixing mechanism includes a stirring shaft extending into the mixing chamber and a number of stirring blades installed on the ...

Problems solved by technology

[0003] In the prior art, the mixer generally includes a mixing mechanism and a mixing chamber for accommodating hot asphalt and dried heated crushed stones. The mixing mechanism includes a stirring shaft extending into the mixing chamber and a number of stirring blades installed on the stirring shaft. Generally, several stirring blades are arranged on the same circumference and form a group. Several groups of such blades are arranged at intervals along the axis of the stirring shaft. This arrangement of the stirring blades, on the one hand, has poor stirring uniformity and poor stirring effect. And the efficiency is low; on the other hand, the mixing mechanism only has a single mixing function, and cannot realize the cutting, crushing and conveying functions of the mixed material after mixing asphalt and stone. If the mixed material is to be transported, an additional screw feeding mechanism must be configured

In addition, the existing mixing blades have a single function and do not have the function of cutting and breaking the mixture
