Wherein, stirring container 1, pivot 2, paddle 3, interior baffle 4, interior platform 5, air flue 6, air inlet duct 7, heating element 8, fan 9.
Detailed Description
The present invention will be further described in detail with reference to the drawings and examples, which are only for the purpose of illustrating the invention and are not to be construed as limiting the scope of the invention.
Examples
As shown in fig. 1, an asphalt concrete heating and stirring device comprises a stirring container 1 and stirring paddles arranged in the stirring container 1; the inner partition plate 4 is detachably arranged on the inner side of the side wall of the stirring container 1, an air cavity is reserved between the inner walls of the stirring container 1 by the inner partition plate 4, the air cavity is communicated with an air inlet pipeline 7, the air inlet pipeline 7 is provided with a heating piece 8 and a fan 9, and a plurality of first air outlet holes are distributed in the inner partition plate 4.
This scheme sets up interior baffle 4 at the lateral wall of stirring container 1, the air cavity of formation is used for carrying steam to stirring container 1 inside, steam is produced through heating element 8 and fan 9, at aggregate and pitch stirring's in-process, continue heating or keep temperature to aggregate and pitch through steam, so that more abundant stirring aggregate and pitch, set up the mode of first venthole through interior baffle 4, can make the better interlude of steam between the aggregate, interior baffle 4 detachable fixed mode can dismantle the raw materials that enters into the air cavity and take out, avoid the accumulation to influence the circulation of air current, steam and aggregate contact more abundant, improve thermal utilization ratio.
