A kind of asphalt stone mixing and stirring heating kettle

Abstract

The invention relates to an asphalt stone mixing stirring heating kettle. The asphalt stone mixing stirring heating kettle comprises a housing; a stirring chamber, wherein the top of the housing is provided with a feed inlet communicated with the stirring chamber; a heating chamber; a heat supplying chamber; a conduction oil circulating system comprising an oil storage tank and a conduction oil pipeline, wherein the conduction oil pipeline and the oil storage tank are communicated; a feed outlet which is arranged at the tail end of the housing, is communicated with the stirring chamber, and is provided with a door cover device; a stirring mechanism comprising a rotatable stirring shaft and a plurality of stirring blades arranged on the stirring shaft; a mechanical chamber, wherein a power device used for driving the stirring shaft to rotate is arranged in the mechanical chamber; and a heating device which is arranged between the mechanical chamber and the heat supplying chamber, and is used for providing heat for the heat supplying chamber. The asphalt stone mixing stirring heating kettle is capable of simplifying traditional preparation technology of asphalt concrete, and heating asphalt concrete, frying stone to be hot, and mixing and stirring at the same time so as to mix materials uniformly; mixing proportion is accurate; quality of obtained mixed material is high; labor consumption is reduced; production efficiency is increased, and production cost is reduced.

Description

technical field [0001] The invention relates to an asphalt stone material mixing and stirring heating kettle. 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. In such a preparation process, heating and melting the asphalt glue and drying and heating the crushed stone are divided into two separate processes, and then mixed and stirred. The heated and melted asphalt and the dried and heated stone are very fast Cooling down quickly makes it difficult to bond the asphalt and stone, making...

AI Technical Summary

Problems solved by technology

In such a preparation process, heating and melting the asphalt glue and drying and heating the crushed stone are divided into two separate processes, and then mixed and stirred. The heated and melted asphalt and the dried and heated stone are very fast Cooling down quickly makes it difficult to bond the asphalt and stone, making the mixture uneven, the mixing ratio inaccurate, and the quality of the mixture not meeting the requirements

In addition, due to the traditional asphalt concrete preparation process with many and cumbersome procedures, it is necessary to manually adjust the ratio of asphalt and stone, which makes it difficult to accurately control the proportion, and consumes a lot of labor. The production efficiency is limited and the cost is very high.
