Urban eco-plant that could produce various type of ready-mixed concrete}

The present invention relates to an eco-friendly urban ready-mixed concrete plant capable of producing a variety of products, and more particularly, having a plurality of storage parts for producing various types of ready-mixed concrete, and having a distribution part for facilitating the distribution of raw materials, The present invention relates to an eco-friendly urban ready-mixed concrete plant capable of producing a variety of materials that can be constructed in an eco-friendly city.

In general, ready-mixed concrete is a building material that mixes cement and aggregate in a plant and transports it to the site using a vehicle with a stirrer.

A vehicle having a stirrer can prevent the ready-mixed concrete from hardening due to agitation by rotation during movement, but it is generally known that the quality of the ready-mixed concrete is degraded when the traveling time is about 1 hour 30 minutes or more. For this reason, the plant producing the ready-mixed concrete is required to be installed very close to the site where the ready-mixed concrete can be used.

However, the construction sites are mainly apartments or buildings, such as in the city center or adjacent to the waiting time for the ready-mixed concrete after the arrival of the site, it is very difficult for the ready-mixed concrete plant to meet these needs.

The obstacles can be divided into economic and environmental factors.

Economic factors are due to the large area of land required for ready-mixed concrete plants. In general, ready-mixed concrete plant is present in a widely dispersed form, such as a storage space for the accumulation of raw materials, a conveying conveyor formed to be inclined long to raise the raw material upwards, and a mixing unit for mixing cement and raw materials. However, this type requires a large area, and the urban area or the surrounding area has a relatively high land price, so the cost of constructing the plant exceeds its profit. If the plant is installed in an area away from the city center to avoid such a high land price, as described above, a vicious cycle in which the quality of the ready-mixed concrete is deteriorated due to the long travel time inevitably leads to the production of the high land price inevitably. none.

Environmental factors are due to dust, which can occur due to the loading of raw materials, dust or falling on long conveying conveyors. In recent years, interest in the air environment such as ultra-fine dust is very high, and the general public has a great feeling about the ready-mixed concrete plant which may adversely affect the air environment, and also due to the deterioration of the aesthetics of the city due to the fixed working environment from the past. It is regarded as a kind of hate facility.

In order to solve this problem, the same design as the urban plant was made, but the plant site was reduced and the effect of suppressing dust generation was obtained, but there was a problem in that it was not practically used because it could not produce various kinds of ready-mixed concrete.

The ready-mixed concrete is required to produce various types of ready-mixed concrete according to its use by mixing various raw materials and cement, but there is a problem that cannot be achieved by the conventional invention.

In general, the transportation of raw materials is carried out by a dump truck that can load cargo. The dump truck tilts the loading tray about 70 to 80 ° to make a slope, and the raw materials are automatically unloaded at the rear bottom of the dump truck. It is taking a way to be.

Raw materials to be unloaded from the dump truck should be transported to the first storage unit 500, which will be described later. The raw material accommodating unit 100 allows the raw materials to be directly unloaded, so that the loss of the process of moving the unloaded raw materials to the transfer means ( There can be no loss.

If the raw material receiving unit 100 is located at a lower position than the dump box height of the dump truck, considering that the present invention is an eco-friendly plant 10 to minimize dust generation, the raw material receiving unit 100 is ground It is desirable to be installed in a closed space formed in a lower place. In addition, since the upper surface should be opened even in the closed space, the upper portion of the closed space may be configured to have a shelter 20 type in order to prevent dust flowing out therefrom.

Preferably, since the dump truck approaches the raw material receiving part 100 by reversing, there is a risk of rear collision, and the eco-friendly plant 10 may be a steel frame structure based on the H beam, so when the dump truck impacts the dump truck. The shelter 20 may be spaced apart from the eco-friendly plant 10, and the raw material accommodating part 100 may extend to a lower portion of the shelter 20. .

The raw material accommodating part 100 is installed horizontally, and thus the received raw material may move horizontally. The moving method may be any method such as a method using a bogie, but is preferably formed as a horizontal conveyor to enable continuous movement of raw materials.

A funnel-shaped hopper 110 may be installed between the ground and the raw material accommodating part 100 to allow the raw material to be removed from the stacker of the dump truck to be efficiently accommodated in the raw material accommodating part 100. In addition, the hopper 110 serves as a primary storage, it can be adjusted to accommodate the appropriate amount of raw material in the raw material receiving portion (100).

Next, look at the vertical transfer unit 200.
