Problems solved by technology

[0002] Most domestic asphalt mixing plant aggregate raw material specifications are not standardized, the raw material supply grading in the production process of asphalt mixing plant and the gradation sieved by the thermal vibrating screen have errors, and some production operators lack experience, etc. The amount of material used in production is not consistent with the corresponding grading feed amount, and some hot silos overflow and some hot silos are short of material, resulting in waste of resources and serious dust pollution. The content of the diameter aggregate makes it difficult for the control system to avoid the overflow phenomenon of the hot silo by controlling the feed volume of the cold silo. How to adjust the feed volume of the cold silo accurately, timely and reliably through the existing technical means, To meet the normal production, while avoiding the overflow phenomenon has become an urgent problem to be solved

Embodiment Construction

[0023] The present invention will be further described below through specific embodiments.

[0024] refer to Figure 1 to Figure 2 As shown in the figure, an asphalt mixing plant that can prevent overflow of hot material silo includes aggregate feeding device 1, aggregate conveying device 2, visual inspection device 3, drying device 4, control device, hot material silo 7, lifting Machine 5, vibration screening device 6.

[0025] The aggregate feeding device 1 includes a plurality of aggregate bins 11, and the plurality of aggregate bins 11 respectively store aggregates of different grades.

[0026] The aggregate conveying device 2 is arranged below the aggregate feeding device 1, and is used to receive and convey aggregates of different grades to the drying device 4 for heating, including a first collecting belt 21 and a second collecting belt 22, The first collection belt 21 is arranged under a plurality of aggregate bins 11 to receive aggregates of different grades and con...

Abstract

The invention discloses an asphalt stirring tower and a method which are capable of preventing hot material bin material overflow. The asphalt stirring tower capable of preventing hot material bin material overflow comprises an aggregate feeding device, an aggregate conveying device, a visual inspection device, a drying device, a hot material bin, and a control device; the aggregate feeding deviceis used for storing aggregates of different grades; the aggregate conveying device comprises a first aggregate belt and a second aggregate belt; an input end of the second aggregate belt is arrangedbelow an output end of the first aggregate belt; the visual inspection device is used for collecting of real-time image information of aggregate falling from the first aggregate belt onto the second aggregate belt, and feedback to the control device; the control device is connected with the aggregate feeding device; preset consuming values of aggregates of different grades are recorded in the control device; the control device is used for analysis the feedback image information from the visual inspection device so as to obtain the real-time discharge amounts of aggregates of different grades,and the discharge amounts of a plurality of aggregate bins are controlled through combination with the preset consumption values of the aggregates of different grades, so that hot material bin material overflow is prevented.
