DETAILED DESCRIPTION OF THE INVENTION
Next will be described more specifically with reference to the flow sheet of FIG. 1 with the above configuration requirements of the present invention. When a building such as a building or a house is demolished, a large amount of waste, that is, concrete such as outer walls, rock wool such as sound absorbing and heat insulating materials, rock chips, wood chips, plastic, glass, steel frames・ Metals such as aluminum are generated. Therefore, concrete, rock wool, wood chips and the like are selected from the wastes collected in the step (a) in the step (b), and these wastes are used as raw materials for building material products. Next, the raw material selected in step (c) is finely pulverized and mixed uniformly, and in step (d), the raw material powder is adjusted to a desired particle size range. Next, in order to facilitate the bonding of the raw material powders in the subsequent pressure molding step, in the step (e), corresponding to the material of the raw material powder, that is, when the material of the raw material powder is wood, a binder (for example, an organic binder) In the case where the raw material powder is concrete or rock wool, cement milk is added to each raw material powder, and the material to be molded as each building material product is prepared by mixing and stirring. The molding material thus prepared is pressure-molded while being heated as necessary in step (f) to obtain a molded product. The shape of the molded product is arbitrary, but a shape such as a square that is usually easy to use as a building material is preferable. Finally, the molded product produced in step (g) is collected and reused as a building material product.
[0007]
Details of this invention are described as an example of a recycling device of the present invention will be described below.
[0008]
FIG. 2 is an explanatory view showing an outline of an apparatus for recycling demolished building waste. This device basically binding agent (binder) solution or cement milk preparation unit 2, a body 5, a systematized device consisting move the casing 6.
[0009]
The main body 5 has a waste input port (hopper) 11 provided at the top thereof, a vertical cylindrical pulverization / mixing unit 51 formed in a lower portion of the hopper and containing a helical stirring blade 12, and the pulverization -It comprises a horizontal cylindrical pressure molding part 52 in which a part of the top part communicates with the bottom part of the mixing part.
Concrete, rock wool, wood chips and the like selected from the waste recovered from the demolished building are put into the pulverizing / mixing unit 51 through the hopper 11. The crushing / mixing unit 51 has a stirring blade 12 having a spiral shape, for example, and the waste that has been charged is finely pulverized by the stirring blade 12 and is uniformly stirred and mixed. The particle size is adjusted, and a raw material powder for molding is prepared.
[0010]
The binder (binder) solution or cement milk preparation unit 2 includes a mixer 21 and a pressure feed pump 22. The binder (binder) solution or cement milk is supplied into the crushing and mixing unit 51 to the pressure feed pump 22. Hose 23 for connecting is connected. Then, corresponding to the material of the raw material powder, that is, when the raw material powder is made of wood, a binder (such as an organic binder) is prepared, and when the raw material powder is made of concrete or rock wool, cement milk is prepared. Is done.
[ 0011 ]
The pressure molding unit 52 is provided with a molded product discharge port 54 that is configured to be opened and closed by a gate valve 53 at one end, and the other end is opened to face a move casing 6 described later.

The move casing 6 is provided concentrically with the horizontal cylindrical pressure molding portion 52, and is capable of sliding along the inner surface of the pressure molding portion 52 on the other released side. The outer diameter is smaller than the inner diameter of the portion 52. A cylinder 7 is provided concentrically and in communication with the move casing 6 adjacent to the outside of the move casing 6 (that is, the side opposite to the pressure molding portion side of the move casing 6).
[ 0013 ]
The move casing 6 and the cylinder 7 have built-in pistons that reciprocate along the respective inner surfaces. The piston 8 in the move casing 6 and the piston 81 in the cylinder 7 are integrally formed via a piston rod 82. ing.
[ 0014 ]
A cylinder 9 located below the move casing 6 is for moving the move casing 6 toward the gate valve 53 while sliding along the inner surface of the pressure mold portion 52 on the other released side. The hydraulic unit 10 installed below the cylinder 7 is for driving the cylinders 7 and 9.
[ 0015 ]
Systematized device this is, as can be moved easily and quickly to the site where a building is demolished, a binder (binder) solution or cement milk preparation unit 2 and body 5 and move the casing 6 and the hydraulic unit 10 is installed on one carriage 4 with wheels attached to the front and rear of the underframe .
[ 0016 ]
In FIG. 2, the portion indicated by a two-dot chain line indicates the position of the piston 8 built in the move casing 6 when the powder material is pressure-molded. The powder material is pressure-molded by the piston 8 and molded. Objects are taken out by opening the gate valve 53 . When the molded product is taken out, the move casing 6 and the built-in piston 8 are retracted to their original positions, and the powder raw material is again filled in the pressure molding unit 52 . Incidentally molded product is cut into appropriate suitable Chi was extracted as building materials size.
