Device and method for monitoring aggregate metering process of forced intermittent asphalt stirring equipment

Abstract

The invention discloses a device and a method for monitoring an aggregate metering process of forced intermittent asphalt stirring equipment, and belongs to the technical field of traffic and building industries. The device comprises at least four thermal aggregate storehouses, an aggregate balance, an asphalt balance, a stirrer, a powder balance, a terminal computer, an acquisition cabinet and a stirring equipment burdening process intelligent metering monitoring device. The method comprises the following steps of: 1, respectively putting screened thermal aggregates into the thermal aggregate storehouses; 2, recording a set amount; 3, recording an open state and a closed state of a discharging door; 4, judging and monitoring material supplementation operation; 5, discharging materials; 6, uploading; 7, putting the weighed aggregates, asphalt and powder into the stirrer for stirring; and 8, judging whether the prepared material is qualified. The device and the method have the advantages that a phenomenon that unqualified commodities are sold at a best price is avoided; a worker can timely acquire material supplementation information and data without going to the site, so that the working time is greatly shortened, and the stability of the quality of a product is improved; the benefit of an enterprise is maintained; and the waste of resources of the nation is reduced.

Description

Technical field [0001] The invention belongs to the technical field of the transportation and construction industry, and particularly relates to a monitoring device and method for the aggregate metering process of a forced intermittent asphalt mixing equipment. Background technique [0002] The main process characteristics of the forced batch asphalt mixing equipment for mixing the mixture are: the asphalt mixture is mixed with hot aggregate, powder, asphalt, etc. in a preset proportion, and its various components are measured in batches (hot bone The material adopts the cumulative weighing mode), the mixer is forcedly mixed according to the pre-set sequence, and the mixed finished material is discharged, and then the next cycle is carried out to form a cycle operation process. Among them, the hot aggregate is classified and sieved by the vibrating screen to form a variety of specifications of hot aggregate, and transport them to their respective storage bins.

Problems solved by technology

[0003] According to the above-mentioned batch measurement method, the current forced batch asphalt mixing station often has no material waiting warehouse or material jam / shortage during the measurement process of various specifications of hot aggregates. In this case, it is necessary to make up Material operation, but now the amount of feeding is calculated in the amount of feeding, that is, the unloading amount of hot aggregate is: M1', M2', M3',...Mn', and the feeding cannot be displayed The amount of the supplementary material is covered up, so that the supplementary material cannot be verified and measured, resulting in an error in the ratio of the mixture, which cannot be detected and has no evidence, which directly affects the quality of the product.

[0004] In the process of modern engineering construction, the requirements for the ratio and quality of asphalt mixture are getting higher and higher, but it is still necessary for supervisory engineers or quality inspection personnel to supervise and inspect the construction site, and conduct sampling in the form of testing to evaluate whether the asphalt mixture meets the standard , this primitive operation not only wastes more manpower and material resources, but also makes the construction work out of touch with the quality inspection work, making it difficult to realize real-time monitoring
