Description

Apparatus for Storing the Aggregate in the Eco? Friendly Batch Plant for Producing Remicon}

The present invention relates to a plant arrangement structure of a ready-mixed concrete factory to implement an eco-friendly low-carbon batch plant for manufacturing ready-mixed concrete, and is used as a raw material of ready-mixed concrete and is temporarily adjacent to the batch plant area. It relates to an aggregate storage device to be stored and a storage structure of water (water).

The present invention relates to a batch plant that produces Ready Mixed Concrete (abbreviated simply as "remicon" or "fresh concrete") and to a ready-mixed concrete plant where it is installed. After the externally open aggregate storage (aggregate stud) is installed in the batch plant area, the aggregates are temporarily stored in this aggregate storage (aggregate stud), and the aggregates stored in accordance with the ready-mixed concrete production process of the batch plant are payloaded. Aggregate conveying device equipped with an engine using oil such as Pay Loader or Shovel Loader is used to transport / inject the aggregate into the inlet of the conveying device (conveyor belt). During transport and feeding operation, foreign matters around the aggregates are scattered and scattered dust is generated. In addition to the environmental detrimental factors, the aggregates were exposed directly to the external environment, which made it difficult to manage the temperature of the aggregates, which made it difficult to maintain the quality of ready-mixed concrete, which is the final product.

In addition, the conventional ready-mixed concrete plant is equipped with a water storage tank on the ground or underground surface to operate the western facilities due to the increase in water temperature during the summer, and to operate the cold-sealed facilities due to the low water temperature in the winter. There was a lot of carbon dioxide emissions from the operation.

1 is a layout and layout of a ready-mixed concrete factory 1 including a batch plant for manufacturing ready-mixed concrete. Referring to FIG. 1 as described above, the conventional ready-mixed concrete factory 1 temporarily stores the aggregate brought in from the outside of the ready-mixed concrete factory 1 using a dump truck DT or the like in the aggregate storage 10. Afterwards, when the aggregate is introduced into the aggregate inlet 20 using the payloader PL, the injected aggregate is stored in the aggregate storage bin 41 of the batch plant 40 by an aggregate conveying device consisting of conveyor belts 30a and 30b. It is equipped with the aggregate conveying system which is conveyed.

Here, the batch plant 40 additionally has cement silos 42a, 42b, 42c, a mixture silo 43, and an admixture storage tank 44, and adjacent to the main material of the ready-mixed concrete The water storage tank 45 is installed.

Although shown in the drawings, a detailed description is omitted, it is composed of a cement transport equipment, mixed material transport equipment, admixture transport equipment, water transport equipment, and aggregate transport equipment.

Such a conventional ready-mixed concrete factory 1 uses the payloader PL to temporarily store the aggregate stored in the aggregate storage 10 inside the ready-mixed concrete factory 1 due to the separation of the aggregate inlet 20 and the aggregate storage 10. As it adopts a system for transporting and injecting the aggregate into the inlet 20, the increase in the use of diesel fuel for the operation of the payloader (PL) causes environmental pollution, and furthermore, the socio-economic due to the excessive emission of carbon dioxide due to the excessive use of diesel fuel. The burden is on the rise, and this is a bigger problem when considering the flow of carbon dioxide regulatory policies to prevent global warming.

In addition, in order to transport the aggregate using the payloader (PL) during the transport and input operation of the aggregate foreign substances scattered around the aggregates scattered by the scattering dust is generated, and also caused by the noise caused by environmental factors In addition, in order to secure a place for depositing aggregates on the ground, it is necessary to secure more than a certain area of the aggregate storage 10, which causes a problem that the area of the entire ready-mixed concrete plant must be expanded, and in the case of aggregates Since it is directly exposed to the external environment such as direct sunlight, it is difficult to manage the temperature of the aggregate, and thus, it is difficult to maintain the quality of the ready-mixed concrete, and to maintain the appropriate aggregate temperature for maintaining the concrete temperature in the summer and winter. And power and diesel (or Due to the increased use of gas, it has been treated as an environmental pollution-generating plant or an excessively carbon dioxide-emission factory, and an improvement plan for reducing the use of electric power and diesel (or gas) is urgently needed.

In addition, the conventional ready-mixed concrete factory 1 installs a water storage tank 50 for storing water (water) for producing ready-mixed concrete in the ground or underground adjacent to the ground surface. And, because the water temperature is lowered in winter to operate the Korea-China facilities, there is a problem that the emission of carbon dioxide is more due to the use of power or diesel for this purpose.

The present invention has been made to solve the above-described problems, suppresses the generation of air pollutants generated from transportation means such as fly dust and payloader generated during the aggregate transport in the ready-mixed concrete factory, and further emissions worldwide Batch structure of aggregate transport and storage devices linked to batch plants in ready-mixed concrete plants to realize eco-friendly low carbon batch plants that minimize the use of electricity and diesel, which are the main sources of carbon dioxide emissions, which are being tightened by lowering the level. And its purpose is to improve the arrangement of water storage devices.

In addition, the present invention is to maintain the temperature of the aggregate and water used in the batching plant of the ready-mixed concrete plant in summer and winter without the need for excessive operation of the western and winter facilities, such as power or diesel (or gas) energy / The improved batch structure of the aggregate transport and storage device and the water storage device in conjunction with the batch plant in the ready-mixed concrete plant, which can produce high quality ready-mixed concrete while minimizing the amount of fuel used to reduce carbon dioxide generation. The purpose is to provide.
