Rubber asphalt mixing device

Abstract

The invention relates to the field of asphalt gravel mixing, in particular to a rubber asphalt mixing device, which includes a mixing box and two mixing units, each mixing unit includes a rotating tube, a heat exchange tube and a number of mixing parts, and each mixing part includes a stirring unit Frame, baffle, slide plate and push plate, one end of the stirring frame is connected with the rotating pipe, the other end of the stirring frame is hinged with the baffle plate, the sliding plate is set on the stirring frame and runs through the rotating pipe, one end of the sliding plate is hinged with the baffle plate, the sliding plate The other end of the push plate can be in contact with the heat exchange tube, and the push plate is fixedly connected with the slide plate. When the technical scheme is adopted, it is beneficial to improve the mixing effect of gravel and asphalt.

Description

Rubber-asphalt mixing device technical field [0001] The present invention relates to the field of asphalt and gravel mixing, in particular to a rubber-asphalt mixing device. Background technique When the crushed stone is lifted to the mixing device by the lifting mechanism to be mixed with the molten asphalt, due to the relatively high viscosity of the asphalt. At the same time, the raw materials between the stirring blades are prone to accumulation during the stirring process, resulting in the mixing of crushed stone and asphalt. The effect is poor, and when the crushed stone at room temperature is mixed with asphalt, it is easy to cause accelerated solidification of the asphalt, thereby affecting the crushed stone and asphalt. Green blend effect. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a device that is conducive to improving the mixing effect of crushed stone and asphalt. In order to achieve the above object, technical ...
