Abstract

PURPOSE:To efficiently and perfectly perform pulverization by together providing a hard material treatment plant and a mixture treatment plant such as a shredder or a rod mill and also providing a mixer in combination therewith. CONSTITUTION:When waste such as concrete is charged in a charging port 1, the waste is roughly crushed by a crusher 6 and finely ground by a hammer crusher 8. When mixed waste of wood, a plastic sheet or the like is charged in the charging port 2, the waste is roughly broken by a shredder g and sent into a rod mill 13 to be further finely ground. When the fine matter falling by a sorter 4 is placed on a bypass conveyor 10, the fine matter bypasses the shredder 9 and treatment quantity becomes the necessary min. The hard waste and soft mixed waste are mixed by a mixer 19. By this method, the treatment and reuse of industrial waste can be simultaneously performed.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention is applicable to so-called industrial waste, which does not deform even when exposed to wind and rain, among industrial waste (hereinafter simply referred to as waste) generated during the construction of buildings or structures. This relates to a treatment plant for five items.

(Prior Art) Concrete and construction material waste includes hard materials such as concrete, soft materials such as wood and plastic sheets, and mixtures thereof. Large amounts of waste are generated, and in its bulky state, it is difficult to use as a landfill, and it also looks bad, making it difficult to find a place to dispose of it. In addition, it was not possible to grind the materials well in the mixed state, and it took time and effort to sort them.

(Problem to be solved by the invention) To efficiently and completely pulverize all types of waste construction materials, such as hard materials, soft materials, or mixtures, to render them harmless and to enable them to be reused as resources. .

(Means for Solving the Problems) A specific example of the present invention will be explained with reference to the drawings. For example, first, a crusher (6) that mainly crushes hard waste such as concrete is connected to an input port (1), Further, a hammer crusher (8) for finely pulverizing the material is connected via a progressive conveyor (7) to form a hard material processing plant.

Secondly, plants for treating soft waste such as wood and plastic sheets will become more efficient.

Furthermore, if a magnetic separator (11) for removing iron and the like is provided at any position on the progressive conveyor (7), iron scraps can be automatically sorted and collected.

A sorter (12) is installed after the shredder (9), or a trommel (14) is installed in front of the mixer (19).
If a sorting machine such as the above is installed and a reflux conveyor (15) for returning bulky items to a shredder (9) or the like is provided in series, it is possible to prevent incompletely processed waste from being sent forward.

Furthermore, equipment for charging soil, transporting soil, removing solid matter, etc. may be installed in front of the mixer tank 19).

The soil feeder (17) uses, for example, a hopper and a packet conveyor so that the soil introduced into the superior entrance (16) is sent to the progressive conveyor (7) in approximately equal amounts. Further, the stone removing machine (18) may be constructed of opposing tapered rollers, and the return conveyor (15) may be extended to send the discharged stones to a shredder (9) or the like.

(Function) At the input port (1), a shredder (9) for breaking hard objects such as concrete lumps and stones and mixed waste of hard and soft materials is connected to the input port (2), Progressive conveyor (
7) to constitute a mixture processing plant.

In this case, it is preferable to provide a blade filter (5) or the like after the input port (2) so that the waste can be fed into the shredder 9) in approximately equal amounts.

Furthermore, a mixer (19) for mixing the processed materials that have been pulverized in both plants installed side by side is installed in series via a progressive conveyor (7) in the front and rear.

The installation site will take advantage of the terrace-like topography to create a step-like structure.
As processing progresses toward lower ground, the energy efficiency of each progressive conveyor improves due to the use of gravity, which is advantageous, but only each inlet may be made higher as shown in the drawing.

(Example) If a slide-shaped sorter (4) is installed in series with the input port (2) and a bypass conveyor (10) is installed to allow fine particles to bypass the shredder (9), etc., the waste of the mixed material will be reduced. When the material is introduced, it is first crushed into coarse particles by a crusher (6>), and sent to a hammer crusher (8) or the like by a progressive conveyor (7), where it is further crushed into fine particles.

When soft waste such as wood or plastic sheets and mixed hard and soft waste are fed into the input port (2), they are roughly shredded by the shredder (9) and transferred to the progressive conveyor (7).
) to feed it into a rot mill (13) or the like to further refine it.

In this case, a slide-like sorter (4) installed at the input port (2)
), the fallen fine objects are transferred to the bypass conveyor (10
>, the shredder (9) etc. are bypassed and the amount of processing becomes the necessary minimum. In addition, if a magnetic separator (11) is provided, iron scraps contained in the waste and decomposed can be adsorbed on the progressive conveyor (7) and automatically sorted and collected.

The fine-grained hard waste, soft waste and mixed waste are combined on a progressive conveyor (7), where coarse waste is sorted by 6- etc. and placed on a reflux conveyor (15), where it is automatically shredded ( You can return to step 9) and reprocess.

Furthermore, residual soil or various types of sludge generated during construction work is mixed with a mixer (19
), it adds appropriate moisture and adhesive strength to the treated waste, does not look ugly, does not scatter dust, is easy to transport, and when used in a landfill and is compressed, it tightens well. At the same time, water permeability and water retention can be adjusted by adjusting the proportion of soil mixed in. In this case, the input soil is sent to the stone remover (18) in approximately equal amounts by the soil feeder (17) and the progressive conveyor (7), from the high part to the low part of the opposing tapered rollers. On the way to the destination, the soil falls between the rollers and rides on the progressive conveyor (7).

Note that only solid materials such as stones are discharged from the lower part of the tapered roller, and the amount is generally small, but if the reflux conveyor (15) is extended, the discharged stones can be automatically shredded. (9) Reflux conveyor to send to etc., 16.
