  As described above, conventionally, production of recycled aggregates has been carried out in a plant that is centralized in one place, but the primary treatment plant that performs the primary treatment of the raw material containing aggregates and the raw material subjected to the primary treatment are processed. There is a demand to provide a secondary processing station that performs the primary processing and the secondary processing in different places. In addition, in this case, it is conceivable that a large number of primary treatment plants are provided and the primary treatment is performed at any of the primary treatment plants, but the production efficiency of recycled aggregates varies greatly depending on which primary treatment plant is selected. It will be. Therefore, the provision of a system capable of appropriately determining which primary processing place to perform the primary processing of the aggregate has been demanded.

  In addition, when the primary treatment plant and the secondary treatment plant are separated, the raw materials are carried into the secondary treatment plant in the state of the primary treatment, so what kind of raw material has been carried into the secondary treatment plant. Confusing. For this reason, there is a problem that it is difficult to appropriately determine to which sales destination the recycled aggregate produced by the treatment at the secondary treatment plant is sold.

  Therefore, in order to solve such a problem, the present invention appropriately selects a primary treatment site suitable for primary treatment of aggregate from a plurality of primary treatment plants, or a reproduction manufactured by treatment in a secondary treatment plant. The purpose of the present invention was to provide a production management system for recycled aggregates that can appropriately select an aggregate sales destination.

  Therefore, the production management system for recycled aggregate of the present invention provided to solve such a problem includes a primary processing step for primary processing of a raw material containing aggregate, and a secondary processing of the raw material processed in the primary processing step. A recycle aggregate production management system for producing a recycle aggregate through a process including a secondary process step, and having an information processing means, where the information processing means performs the primary process step. A primary treatment plant suitable for performing the primary treatment is selected based on the primary treatment plant location data relating to the raw material and the raw material location data relating to the location of the raw material to be recycled.

  With the configuration as described above, it is possible to appropriately select a primary treatment site suitable for the primary treatment of aggregate from a plurality of primary treatment plants, and perform the primary treatment and the secondary treatment in separate treatment plants. This makes it possible to smoothly produce recycled aggregates.

  In the above-described recycled aggregate production management system, it is desirable that the sales destination can be selected based on the purchase request data regarding the recycled aggregate desired to be purchased by the sales destination and the raw material data regarding the state of the raw material.

  With the configuration as described above, it is possible to select an optimal sales destination for recycled aggregates manufactured by processing at the secondary treatment plant based on the purchase request data regarding recycled aggregates desired to be purchased at the sales destination. A series of flows from the production of recycled aggregates to sales can be smoothly advanced.

  According to the present invention, it is possible to appropriately select a primary processing plant suitable for primary processing of aggregates from a plurality of primary processing plants and a sales destination of recycled aggregates manufactured by processing in the secondary processing plant. It is possible to provide a production management system for possible recycled aggregates.

Next, a recycled aggregate production management system 1 (hereinafter also simply referred to as a management system 1) according to an embodiment of the present invention will be described in detail with reference to a method for producing a recycled aggregate.
First, a method for producing a recycled aggregate will be described. A recycled aggregate is roughly manufactured according to a manufacturing flow composed of a primary processing step and a secondary processing step as shown in FIG. 1 and FIG. The primary treatment process is performed at the primary treatment plant, and the secondary treatment process is performed at the secondary treatment plant.

  In the method for producing a recycled fine aggregate carried out in the present embodiment, a lump of concrete waste material (hereinafter referred to as a concrete lump B as required) first generated at a building demolition site or the like is disposed of the concrete lump B. From the requester Ap (p = natural number) to one of a large number of primary processing fields Fq (q = natural number).

  Specifically, the concrete block B transported to one of the numerous primary treatment plants Fq is put into a hopper 10 provided in the plant. After that, the concrete block B put into the hopper 10 is transferred by the reciprocating feeder 11 which is reciprocating and is put into the jaw crusher 12 (crusher). When the concrete block B is thrown in, the jaw crusher 12 has a fixed plate 13 and a movable plate 16 that reciprocates in a direction approaching and separating from the fixed plate 13 as the rotating body 15 rotates. The jaw crusher 12 crushes the concrete block B introduced between the fixed plate 13 and the movable plate 16 to obtain a concrete crushed material V. Thereby, the primary processing is completed.

  When the primary treatment is completed as described above, the concrete crushed material V is transported from the primary treatment plant Fq to the secondary treatment plant S by a ship or a truck. In the secondary treatment plant S, the concrete crushed material V is secondarily treated to produce recycled aggregates (recycled coarse aggregate, recycled fine aggregate). If it demonstrates in detail, a secondary process will be implemented through each process of a selection process, a grinding process, a specific gravity selection process, and a separation process.

  The sorting step is a step of classifying the concrete crushed material V according to the particle size. The sorting step is performed by putting the concrete crushed material V into the vibrating sieve 20. When the concrete crushed material V is classified by the vibration sieve 20, the treatment process proceeds to the grinding process.

  In the grinding process, those having a large particle size and those having a small particle size among the crushed concrete V classified in the sorting process are separately ground in the grinding machines 21 and 22. The concrete crushed material V having a large particle size ground by the grinding machine 21 is in a state where the mortar component adhering to the crushed material V is peeled off and discharged as a mixture with the mortar component.

  In the grinding process as described above, the concrete crushed material V having a large particle size ground by the grinding machine 21 corresponds to the coarse aggregate (recycled coarse aggregate) in the specific gravity sorting process and the mortar content. And sorted. Specifically, in the specific gravity sorting step, a mixture of the mortar content discharged from the grinding machine 21 and the concrete crushed material V is input to the specific gravity sorting device 23. In the specific gravity sorter 23, both are sorted using the specific gravity difference between the concrete crushed material V and the mortar content.

  More specifically, the specific gravity sorting device 23 used in the present embodiment stores treated water therein, and the water level of the treated water is corrugated in the vertical direction by supplying and exhausting air. It is possible to put it on. When the mixture of the mortar and the concrete crushed material V is put into such a specific gravity sorting device 23, the concrete crushed material V having a large specific gravity will eventually sink in the water, and the mortar will float on the water surface side. The concrete crushed material V thus selected has a coarse aggregate as a main component and can be used as a recycled aggregate. Therefore, the crushed concrete V to which the mortar portion sorted by the specific gravity sorter 23 is hardly attached is recovered as a usable recycled aggregate. Further, the mortar portion selected by the specific gravity separator 23 is collected separately from the recycled aggregate, separated from the water in the thickener 25 and discarded.

  On the other hand, the crushed concrete V having a small particle size ground by the grinding machine 22 in the above-described grinding process is separated into a fine aggregate (recycled fine aggregate) and other things in the separation process. The Specifically, in the separation process, the concrete crushed material ground by the grinding machine 22 is input to the spiral classifier 26 and can be used as recycled fine aggregate, and waste such as mortar and impurities. And separated. Waste such as mortar is separated from water by the thickener 25 and discarded.

Are also input based on data transmitted from the client Ap. Based on the raw material location data and raw material data, the management system 1 selects a primary treatment site Fq suitable for primary treatment of the concrete block B to be disposed from a plurality of registered primary treatment plants Fq. Specifically, the management system 1 is used to process the concrete lump B to be processed on the basis of data on the location of the primary treatment plant Fq registered in plural (hereinafter also referred to as primary treatment plant location data). Narrow down the suitable primary treatment plant Fq. Then, the management system 1 selects the primary processing site Fq closest to the location of the client Ap or the concrete block B from the primary processing sites Fq thus narrowed down.

  When the primary treatment plant Fq is selected as described above, the data (primary data) that instructs the primary treatment of the concrete block B toward the corresponding primary treatment plant Fq or a terminal (not shown) provided to the client Ap. Processing instruction data) is transmitted. Based on the primary processing instruction data, the concrete block B is transported from the client Ap toward the selected primary processing site Fq.

  The management system 1 also provides raw material data relating to the state of the concrete block B carried into the primary treatment plant Fq, and recycled aggregates (recycled coarse aggregate, recycled) that are desired to be purchased at the customer Cr (r = natural number). Recycled aggregates (recycled coarse aggregate, recycled fine aggregate) manufactured by processing at the secondary treatment plant S based on data (hereinafter also referred to as purchase request data) on the amount and type of fine aggregate) Select a sales partner Cr suitable as a sales destination. Then, the management system 1 transmits data indicating the selected sales destination Cr (hereinafter also referred to as sales destination instruction data) to a terminal (not shown) provided in the secondary processing site S. The recycled aggregate manufactured at the secondary treatment plant S is transported to the selected sales partner Cr based on the sales destination instruction data.

  The management system 1 described above can select a primary treatment site Fq suitable for performing the primary treatment of the concrete block B based on the raw material data, the raw material location data, and the primary treatment site location data. Therefore, according to the management system 1, even if the primary processing and secondary processing of the production of the regenerated aggregate are performed in separate processing plants, the production of the regenerated aggregate can be performed smoothly.

  The management system 1 described above is based on purchase request data relating to recycled aggregates desired to be purchased by the customer Cr and raw material data relating to the raw material state of the recycled aggregates. It can be selected. Therefore, according to the management system 1 described above, it is possible to smoothly perform a series of processes from production to sale of recycled aggregate.
