Detailed Description
The present utility model will be described in further detail below in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the detailed description and specific examples, while indicating the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs, and the terms used herein in this description of the utility model are for the purpose of describing particular embodiments only and are not intended to be limiting of the utility model.
In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of description and simplification of the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the protection of the present utility model.
As shown in fig. 1 and 2, the ventilation device for the asphalt stirrer comprises a first pipeline 1, a second pipeline 3 and a third pipeline 6 which are connected in sequence;
the upper end of the first pipeline 1 is connected with the hot aggregate bin 12, the lower end of the first pipeline is connected with the upper end of the second pipeline 3 through the double-flange butterfly valve 2, the lower end of the second pipeline 3 is connected with the upper end of the third pipeline 6 through the first hose 1, and the lower end of the third pipeline 6 is connected with the asphalt stirrer 14;
the first pipeline 1 is connected with a branch pipe 8, the branch pipe 8 is connected with a connecting pipe 10 through a second hose 9, and the connecting pipe 10 is connected with a powder weighing hopper 11 and is used for discharging gas in the powder weighing hopper 11 together.
As an improvement of the embodiment, as shown in FIG. 1, the first pipeline 1 and the third pipeline 6 are respectively provided with an access hole and a sealing plate 7, the access holes facilitate cleaning dust in the pipeline in the later period, and further, the sealing plates 7 are installed on the first pipeline 1 and the third pipeline 6 by bolts, so that the disassembly and assembly are more convenient.
As an improvement of the embodiment, as shown in fig. 1, the first hose 1 is connected with the second pipeline 3 and the third pipeline 6 through the flange 5, the second hose 9 is connected with the branch pipe 8 and the connecting pipe 10 through the flange, and the whole structure is more convenient to assemble. The first hose and the second hose are convenient for connecting the pipelines, and meanwhile, when the pipelines work, the vibration of the pipelines can be relieved.
As an improvement of the embodiment, the pipe diameter of the branch pipe 8 is smaller than that of the first pipeline 1 because of less gas in the powder weighing hopper 11, and the pipe diameters of the first pipeline 1, the second pipeline 3 and the third pipeline 6 are the same, so that the gas can smoothly circulate.
When the device is used, as shown in fig. 2, when the hot aggregate bin 12 is discharged into the asphalt stirrer 14 through the aggregate weighing hopper 13 to stir, gas in the asphalt stirrer 14 can be rapidly discharged after sequentially passing through the pipeline III 6, the pipeline II 3 and the pipeline I1, the accuracy of metering is prevented from being influenced by the aggregate weighing hopper 13, and a small amount of gas in the powder weighing hopper 11 can be discharged through the ventilation device.
According to the ventilation device for the asphalt stirrer, the pipeline is independently added to the upper part of the asphalt stirrer, so that the asphalt stirrer is connected with the hot aggregate bin, the problem that the accuracy of a metering scale is affected because gas cannot be rapidly discharged is solved, and meanwhile, the gas flow in the pipeline can be regulated, so that the gas in the asphalt stirrer can be rapidly discharged without passing through an aggregate weighing hopper when the hot aggregate bin is fed, the stability and the accuracy of metering are ensured, and the service life of the sealing device is prolonged.
