Overflow pipe and asphalt stirring equipment

Abstract

The present invention provides an overflow pipe and asphalt stirring equipment, wherein the overflow pipe comprises a pipe body and a separation mesh structure arranged in the pipe body, and the separation mesh structure has a preset distance from the inner wall of the pipe body. According to the present invention, the separation mesh structure is arranged in the pipe body, and has the preset distance from the inner wall of the pipe body, such that the aggregate contacts the separation mesh structure and the aggregate positioned between the separation mesh structure and the inner wall of the pipe body, and cannot contact the inner wall of the pipe body, and the wear resistance of the overflow pipe can be increased while the vibration reduction and the noise reduction of the separation meshstructure and the aggregate are used.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an overflow pipe and an asphalt mixing device. Background technique [0002] At present, the overflow pipes of asphalt mixing equipment mostly adopt the following two methods: the first method is as follows: figure 1 As shown, the vertical pipe body 12' and the inclined pipe body 14' of the overflow pipe 1' do not have any noise reduction treatment, the overflow speed is fast, and the larger particle aggregate will repeatedly hit the pipe wall, and the smaller size aggregate It will rub against the pipe wall to cause noise and large vibration; the second way is as figure 2 As shown, a wedge-shaped block 16' is arranged in the inclined pipe body 14' of the overflow pipe 1', and the vertical pipe body 12' is not processed, but it can only play the role of local buffer overflow. Contents of the invention [0003] The present invention aims to solve at least one of...
