Description

INSTALLING METHOD OF A PREFABRICATED BATCHER PLANT}

The present invention relates to a method for installing a prefabricated batcher plant, and more particularly, to modularize each component of the batcher plant into a first unit and a second unit so that the batcher plant can be prefabricated and also separated and transported. A prefabricated batcher plant facility.

The batcher plant refers to a facility for manufacturing ready-mixed concrete by combining functions such as a material storage device, a metering device, a mixer, and a discharge device of mixed concrete. The ready-mixed concrete is then supplied to the construction site in a mixer truck. 1 shows the structure of a conventional general batcher plant.

As shown in FIG. 1, aggregate such as sand and gravel is input to the aggregate hopper 110, and weighed in an appropriate amount by the aggregate meter 120, and is introduced into the mixing mixer 140 through the belt conveyor 130. In addition, the cement is stored in the cement silo 150 and introduced into the mixing mixer 140 through the cement meter 160. Admixtures and water are added to the mixing mixer 140 through the admixture and the water meter 170. In this way, the cement, aggregate, admixture, water, and the like introduced into the mixing mixer 140 are mixed with each other and are contained in the Racon truck 180 waiting at the bottom and transported to the construction site.

Batcher plants come in a variety of forms, from large to relatively small, especially for smaller constructions. After the tunnel construction, the batcher plant has to be moved to and installed near the work site for use in another tunnel construction. In the conventional batcher plant 100, each component is not modularized, which makes dismantling work very inconvenient. In particular, there are various inconveniences such as the use of the oxygen cutter during the dismantling operation, it takes a lot of work time even when re-installation, and adjustment work is required. In addition, electrical wiring should be reconnected when re-installed after disassembly and disassembly. In most cases, the ready-mixed concrete ready to be used cannot be reused, and in this case, a new wire must be purchased and wired. In particular, problems with transport due to various parts of irregular volume. Therefore, there has been a demand for a prefabricated batcher plant that is easy to install and disassemble in a prefabricated manner, and has a module type of an appropriate size.

In addition, the prefabricated batcher plant arranges and fixes the mixer and the meter in the proper position in the upper and lower two-sided frame structures, and when the frame structure is correctly positioned, the mixer and the meter should be configured to automatically fit. . However, in such a prefabricated batcher plant, the belt conveyor is formed to a considerable length, and such a belt is a problem in constructing a prefabricated batcher plant module because it is difficult to separate or fold and transport the middle part.

In addition, as shown in Figure 2, the belt conveyor 130 of the conventional batcher plant is composed of a belt conveyor for transporting sand and gravel, respectively, and thus has a configuration that requires at least two long belt structure. Using a belt conveyor of such a structure is impossible to modularize the overall batcher plant equipment, there is a problem that difficult to transport and reinstall. Therefore, the batcher plant using the new belt conveyor which improved the structure of the belt conveyor was studied.

The present invention is to solve the problems as described above, by modularizing the various components used in the batcher plant into a first unit and a second unit prefabricated batcher that can be easily disassembled, transported and reassembled the batcher plant equipment It is an object to provide a method for installing plant equipment.

In addition, the present invention includes a terminal box for driving each component or applying a stop and control signal to the first unit, the prefabricated batcher plant installation method for simplifying the electrical wiring when disassembly and reassembly of the batcher plant The purpose is to provide.

In addition, the present invention is a prefabricated batcher using a belt conveyor to facilitate the disassembly, transportation and reassembly of the batcher plant equipment by using and arranging the belt conveyor used in the prefabricated batcher plant as the first and second belt conveyor. The purpose is to provide a plant installation method.
