Abstract

This design manufactures artificial aggregates by mixing industrial wastes such as coal ash from thermal power plants, steel dust from steel mills, sewage sludge from paper mills, and manufacturing artificial aggregates to prevent environmental pollution, reuse waste resources, and save clay resources at the same time. It relates to a manufacturing apparatus.

Until now, there have been a number of proposals for patents and literature on artificial aggregate manufacturing method using the waste, but it was not easy to carry out. In other words, aggregates have various uses, such as construction, civil engineering, or soundproof panel production.They must maintain a certain mechanical strength after their size is mixed with other mixtures such as cement and cured like natural gravel. It should be possible because it is difficult to maintain not only the proper size, shape and mechanical strength, but also the requirement of continuous mass production.

Artificial aggregate manufacturing process consists of raw material supply-mixing-maturing-primary molding-cutting-spherical body manufacturing-molding drying-firing-cooling-roughly nine processes, the present invention is finely divided-spheroidization-drying and cooling The facilities required for the process have been improved.

In order to maintain the mechanical strength of artificial aggregates, the present invention draws a mixture of clay and the waste by forging a solid fillet as a potter's machine (molding machine) to maintain the mechanical strength of artificial aggregates. It is continuously cut into three slicers, and the sliced slices are put into a centrifugal globule maker to make a ring. It is a device to send the annular aggregate molded body to the steel mesh bucket conveyor dryer, and then to dry it and then to the kiln for high temperature baking at 1100 ~ 1200 degrees Celsius and finally to the steel mesh bucket conveyor cooler to cool the plastic body.

As described above, the present invention is to enable the continuous mass production of artificial aggregate having the size and shape of the aggregate and the appropriate mechanical strength, which was impossible in the past.

      In the process of manufacturing artificial aggregate by mixing waste with clay. As shown in Fig. 1 and Fig. 8, raw material supply-mixing-maturation-primary molding-fine cutting (square cutting)-spherical manufacturing-drying-firing-cooling-it consists of approximately nine processes, in particular In the artificial aggregate manufacturing equipment of the waste mixture, although the above-mentioned three steps-spherical body manufacturing-drying 3 process are important processes for manufacturing aggregate moldings, the conventional manufacturing equipment has a lot of defects, such as not easy cutting of aggregate moldings, so that continuous mass production There was a problem. Herein, the aggregate molded body is obtained by cutting the primary molded fillet drawn from the molding machine into a size having an apparent diameter of about 15 to 20 mm and having the strength of the primary molded body.

 Referring to the process-specific problems in the conventional artificial aggregate manufacturing equipment is as follows. First, as shown in Patent Application No. 10-0530089 for making aggregate molding, as shown in FIG. 2, the porous disk at the outlet of the primary molding machine for the purpose of making the aggregate molding at the same time as the primary molding. There are many problems such as the draw load is large and holes are easily clogged by attaching a plurality of thin melodies at a time, and as another example, it is proposed that the first molding machine has a relatively large number of layers from the outlet. After drawing a thin plate and cutting it with so-called 'rotating roller' which rotates with a lot of cutting blades, this also has the frictional resistance that is produced at the draw hole of narrow and long hole. Since several units are required, there are problems such as complicated lines. Therefore, in order to make drawing easier, there are cases in which water is mixed and drilled, which has good fluidity of the primary molded body, but there is a problem of increasing moisture content of the product after firing as well as long drying time of aggregate molded body.

   Next, when the spherical body manufacturing process of the section is seen, conventionally, as shown in Fig. 2, "A", the molded body of the long cylindrical body (50 'with the outlet side inclined is installed inclined and the rectangular molded body in the body 51'). Put 88 to roll at a suitable speed to make a rounded shape.88) Put the surface of the square aggregate molding 88 evenly on the inner surface of the cylinder in the manner of putting the cylindrical surface in the rotating cylinder to roll the circumferential surface. The longer you make contact, the closer you are to the garden. However, the problem with the conventional horizontal positioning type rotary molding machine 51 'is that since the aggregate molding 88 is driven only downward, the circumferential surface to which the molding 88 touches at the time of rotation is the lower edge and the other side and the upper surface are idling. . Therefore, the diameter of the fuselage 51 'becomes larger in proportion to the mass production facility, and the idling surface becomes wider, which is inefficient. When the aggregate aggregate 88 is filled in at least 15% of the diameter of the fuselage 51 ′, some aggregate aggregates 88 form a layer, so that the spheroidizing efficiency is lowered.

  In the method of drying the annular molded body 88 'in the spherical body drying process, the exit body is inclined to rotate and elongate like the horizontally mounted rotary type molding machine 50' of FIG. In the '), the molded body 88' is put in a manner of rolling and sending hot air at the same time as the rolling, and this also uses a method of drying the molded body 88 'because it flows to the bottom so that the heat is passed upward and the heat transfer efficiency is not good. There is also a problem in that it does not discharge moisture evaporated from '). More importantly, the less rigid molded body 88 'must be rolled for axial transfer, which may be undesirable as it may promote internal cracking of the molded body 88' while rolling.

The present invention is a method of supplying and mixing the raw materials and hardly drilled and molded according to the conventional method, in order to improve the problems in the conventional cutting method described above, the present invention is first [FIG. 2] Incline the outlet 2 side of the main body 1 of the molding machine as shown in " B " and attach the fillet inlet 3 to naturally draw the primary molded fillet 8, and then the 3-stage washing machine 40 composed of piano wires. In this order, the fillet (8) is continuously split into square shaped bodies in the order of terminating in one step, transversing in two steps, and disconnecting into a cylinder in three steps. The tilting of the molding machine outlet 2 is to obtain the weight by gravity as the fillet 8 is drawn out.

The subject innovation is to make the aggregate aggregate 88 round, without using the conventional horizontally mounted rotary type molding machine, the subject innovation is to put the molded body 88 in the vertical installation centrifugal sphere spherical body maker 50 to rotate at high speed.

In the method of drying the aggregate molded body 88, the present invention is to install a steel wire bucket conveyor in the chamber 61 to trap the heat and exhaust as shown in [FIG. 1] and [FIG. 5] without using a conventional horizontally mounted rotary dryer. The molded article 88 'is loaded thereon and dried by the heat entering the lower portion of the bucket 66A. That is, the hot air enters under the bucket 66A in the chamber 61 and passes between the molded articles 88 'contained in the steel mesh bucket, and heats the molded articles 88', and the waste heat is discharged upward with the moisture. The drying temperature and time are made possible by adjusting the speed of the conveyor 66 and the air volume of the blower 67.

The kiln according to the present invention adopts a conventional rotary kiln 70, and operates at about 1100 degrees C to 1200 degrees C by connecting the dryer outlet side and the inlet side of the cooler as shown in [FIG. 1] and [FIG. 6].

In the subsequent process of the cooling device, the present invention installs a steel mesh bucket conveyor passing through the chamber 81 as shown in FIGS. 1 and 7, and loads a molded object 88 ′ thereon to load the chamber 81 into the chamber 81. Cold air is blown into the lower portion of the conveyor bucket (86A), and the heat passes through the granules (88 ') to receive heat, and the waste heat is sent through the duct to the dryer 60 to save energy.

      The present invention is a process for mixing and tightly molding the supply of raw materials as shown in [Fig. 1] to produce an artificial aggregate is configured by a conventional method, but the molding machine outlet (2) is [Fig. 1] and [Fig. 40 degrees downward and attach the draw opening 3 to the inclined surface, so that the primary molded fillet 8 is inclined and drawn.

  The cutting process of the present invention is first performed in order to split the primary molded fillet 8 drawn out from the drawing outlet 3 attached to the molding machine outlet 2, such as "a" and "b" of FIG. The roller conveyor 31 is inclined to the molding machine outlet 2 in the same direction as the molding machine outlet 2 so that the self-weight of the fillet 8 is pushed to generate a pushing force, and then the fillet 8 is connected to the piano wire without applying external force. It feeds to the three-step cutter 40 consisting of (441, 442, 443).

 The three-stage shredder 40 is composed of a breaker 43 which is operated by the longitudinal section 41, the transverse section 42 and the cylinder 45 and the rail 46 as shown in the "I" of FIG. The bolts 47B are assembled and set in sequence, and the piano wires 441, 442, and 443 use high tensile steel or stainless steel having a diameter of about 0.5 mm. Since the three-stage cutting machine has to change the mesh according to the size of the product to be produced, it is easy to attach and detach by making a cartridge standardizing each frame (41, 42, 43). The distance between the longitudinal end 41 and the transverse absolute 42 and the breaker 43 is preferably spaced at least 5 cm in order to reduce the frictional resistance by the piano wire. In order to further reduce the frictional resistance of the piano wire, the device will be more complicated, but the cylinder 45 and the guide 46 are attached to the frame of the longitudinal end 41 and the transverse absolute 42 one by one, that is, the piano wire 441 (442) There is also a way to make the linear movement.

And the square three pieces, that is, the aggregate molded body 88 of each phase that passed through the shredder 40 is still in the state of viscous force so that the powder storage tank (B1) as shown in FIG. The pipe P1 is installed and connected to the upper portion of the hopper 22 so that the dehumidifying powder is sprayed. The powder storage tank B1 stores fine and dry stone powder or a dehumidifying agent or a fastener.

   Centrifugal force spherical body maker 50 of the present invention is installed in the outer cylinder 51 having the inlet 58 and the outlet 59, the inner cylinder 52 and the outer cylinder 51 and the inner cylinder 52 as shown in FIG. The guide vanes 53 and 53 'on which the aggregate formed body 88 is to be rolled in the space between the walls are attached several times to make a cylindrical rotor, and then the body 51 is installed perpendicular to the swivel, and then driven. The pulley 54, the driven pulley 56, and the motor 55 are attached so that centrifugal force is generated during rotation. This centrifugal force pushes the aggregate molded body 88 to the circumference and rolls it further.

In order to dry the spherical annular shaped body 88 ', the dryer of the present invention has a flat wire mesh bucket 66, an RF type conveyor chain 64, and an attachment, as illustrated in FIG. A conveyor consisting of a conduit 63, a chain sprocket 65, and the like, installed in a chamber 61 receiving hot air, connected to a track, and then driven such as a reducer motor 62 and a sprocket 65, 65 '.

Complete manufacturing equipment

        The present invention configured as described above uses a conventional molding machine to obtain the pressing force to the three-stage cutting machine 40 by gravity by drawing the primary molded body 8 to the inlet 3 inclined downward by about 40 degrees. The three-stage cutting machine 40 of the fillet (8) and the self-feeding the sum of the ejection force of the molding machine (1) is automatically fed, a set of longitudinal section 41, transverse section 42 and breaker (43) Since it is assembled in series in the furnace, it is possible to continuously divide into the square-shaped molded body 88 at the same time of feeding and the equipment itself is compact. When the rectangular molded object 88 falls into the hopper 22, by spraying the powder B2, the rectangular molded object 88 having a viscous force does not break up and get stuck together.
