Circulating aggregate cement paste using a rotating friction of the rotating trommel hammer and paddle according to the present invention to reduce the circulating aggregate cement paste foreign matter, the conventional building or civil works to demolish the concrete, re-generated concrete It is a device that can be produced and manufactured into recycled aggregate. Therefore, the configuration of the present invention and its operation will be described with reference to FIGS. 1 to 7.

As shown, the present invention has a conveying means 12 for transferring the aggregate falling from the hopper 13 installed on the top of the frame 11 to the belt rotated by the motor, the aggregate conveyed in front of the conveying means 12 There is an aggregate input portion 10 consisting of a guide panel 14 for guiding the inside of the trommel 15, the trommel 15, Trommel installed to be rotatable in the rear of the aggregate input portion 10 A pair of paste separators 20 for separating the paste by striking the aggregate with the rotational force on the inner left and right sides of the 15, and the main gear 17 fastened around the outer peripheral surface of one side of the trommel 15 and the outer peripheral surface thereof The main motor 16 which is connected to the shaft sprocket of the motor installed on the side of the chain 18 trommel 15 to rotate the trommel 15, the first end of the hollow trommel 15, is raised to a high level and rearwards. Is a support frame (31) for lowering to a low level There is a paste separation unit 30 consisting of. These are combined with each other to rotate and rotate the circulating aggregate inside the trommel (15) to separate the paste contained in the aggregate and reproduce the aggregate.

That is, the present invention is a production apparatus for collecting only aggregate from the crushed concrete pile of the concrete structure to be treated as waste for use in the construction of other buildings or civil construction.

First, before the construction waste is added to the present invention, it is common to go through a separate shredding process. After the first crushed by the jaw crusher (Jaw Crusher) by putting in a hopper (hopper), the first sorting to 150 ~ 200mm with a sorting machine or the lower portion of the jaw crusher (Jaw Crusher) is put into the present invention. In addition, through this process, that is, the second crushed with a double jaw crusher (Double Jaw Crusher), and then sorted 75 to 100mm with a sorting machine or the second may be put into the circulating aggregate production device of the present invention. Of course, the secondary sorted recycled aggregates are crushed with a cone crusher for the third time, and then sorted three times at 40 mm with a sorter or with a crusher, and the third sorted recycled aggregates are sand crushed with a sand crusher. After crushing the car, the screen is divided into 5mm or less with a vibrating screen, and then put into the peeling part of the present invention to improve the removal and shape of the paste, such as mortar, while washing with spraying water on the vibrating screen. It is also put into the hopper of the present invention. In fact, the start of the input is preferably set differently depending on the size and condition of the shredded construction waste.

In any case, the construction waste selected to a certain size through the above-described shredding operation is put into the aggregate input unit 10 and transported, and the paste is completely separated through the paste separation unit 30 and regenerated into aggregate. The method is as follows. As shown in Figure 1, when the construction waste is passed through the crusher, such as the crusher described above, and introduced into the hopper 13 of the aggregate input section 10, the illustrated conveying means formed at the bottom of the hopper 13 ( 12) is formed. The transfer means 12 is made through the motor and the belt, the motor rotates to move the construction waste inside the hopper 13 by interlocking the belt. The transfer means 12 used in the present invention was carried out using a motor and a belt, but is not limited thereto. Aggregate may be transferred using vibration, or a separate push bar may be formed to transfer aggregate. The method of transferring using the motor and the belt has the advantage that the conveying operation can be performed most conveniently because the amount of construction waste conveyed can be adjusted by varying the rotational speed of the motor. More specifically, the rotation speed of the motor is controlled through an inverter (not shown).

In any case, the conveyed construction waste moves to the front guide panel 14 of the belt. The guide panel 14 is located in the front of the trommel 15 in the configuration included in the conveying means 12 to move in the belt construction waste falling from the end can enter the inside of the trommel 15 accurately It serves as a guide.

The trommel 15, which is the paste separation unit 30, rotates in a cylindrical shape and separates the aggregate and the paste from the construction waste put into the inside. The guide panel 14 guides the building waste accurately to the inside of the trommel 15.

The present invention then separates the paste due to the overall action of the various configurations inside the trommel 15. That is, the paste separation device 30, the trommel 15 of the present invention forms a separate shaft (K) that rotates in the inside, the hammer (23) and paddle 24 on the shaft (K) To form the hammer 23 to hit the building waste, and the paddle 24 to hit to separate the paste. When the construction waste is introduced into the trommel 15, the cylindrical trommel 15 rotates. According to this rotation, the building waste generates friction with the inner circumferential surface of the trommel 15 inside the trommel 15, and the aggregate and the paste are separated. In addition to this, in the present invention, the hammer 23 and the paddle 24 described above are also rotated to separate the paste. Firstly, through the trommel 15, secondly through the hammer 23, thirdly through the paddle 24, it is possible to produce a more qualitative circulating aggregate for peeling and sorting the paste.

Then, the principle that the trommel 15 of the present invention rotates. Trommel 15 is in the form of a circular drum, as shown. The main gear 17 which is protruded and fastened is fastened to the outer peripheral surface of the trommel 15 of a drum shape. The main gear 17 may be formed at one side of the outer circumferential surface of the trommel 15, but is preferably formed at the first end of the trommel 15 inlet. The main gear 17 fastened to the outer circumferential surface of the trommel 15 is in a state in which the chain 18 is wound. In addition, the chain 18 is connected to the sprocket fixed to the shaft end of the coarse motor 16 fixed to the side. Therefore, when the main motor 16 rotates, the chain 18 is interlocked, and the main gear 17 is rotated in accordance with the interlocking force of the chain 18. Since the main gear 17 is formed on the outer circumferential surface of the trommel 15, the main gear 17 rotates the trommel 15. In addition, in order to compensate for the sagging of the chain 18 generated in the temperature difference between winter and summer, the present invention includes a separate tension adjusting means 44 as shown in FIG. It is to adjust the tension by engaging the interlockable sprocket 45 or the roll to be able to maintain a certain degree of interlocking by the elastic force of the spring and to press one side of the chain 18.

Eventually, the present invention inserts construction waste into the cylindrical trommel 15, and the aggregate and paste are separated through friction by rotating the trommel 15 and the paste separation device 30 inside the trommel 15. It's a device to pull off.

Then, more detailed embodiments of the present invention will be described with reference to the drawings. 1, 4, 6 and 7, the paste separator 30 has a shaft K which penetrates the inside of the cylindrical trommel 15 and is installed one by one in both the left and right sides of the lower side, and the shaft K There is a bearing 22 is fixed to both ends of the), there is a rotating motor 21 is fixed to one end of the shaft (K). In addition, there are a plurality of hammers 23 fixed to the outer peripheral surface of the inlet shaft K of the trommel 15 at regular intervals, and fixed to the outer peripheral surface of the rear shaft K of the trommel 15 at regular intervals. There are a number of paddles 24. Therefore, by combining them, the circulating aggregate flowing into the trommel 15 is blown to remove the paste component fixed to the outside.

That is, the paste separator 30 of the present invention is provided with a pair of shafts K penetrating the inside of the trommel 15. The shaft K is formed at both left and right sides of the inner lower portion of the trommel 15, and is connected to the shaft of the rotation motor 21 fixed to the rear of the trommel 15. When the rotation motor 21 rotates, the inner shaft K of the trommel 15 rotates. Importantly, the hammer 23 and the paddle 24 are fastened to the outer circumferential surface of the shaft K. Referring to the longitudinal direction of the trommel 15, the hammer 23 is fastened to the inlet side of the trommel 15, the paddle is fastened to the rear side of the trommel 15. Building waste introduced into the trommel 15 is rubbed with the inner circumferential surface of the trommel 15, and some paste is peeled off. The construction waste which was peeled off and flowed down into the inclined trommel 15 is broken by the hammer 23 rotating inside the trommel 15 and the paste is peeled off. It will be peeled off in a thicker form. Afterwards, the construction waste, which has entered further, is neatly peeled to the fine paste by friction with the paddle 24. Trommel (15), hammer (23), through the paddle (24) is peeled in multiple stages, in fact the circulation aggregate according to the present invention is excellent in quality.

The peeled paste is removed, and only the recycled aggregate is reproduced and used, and the manner in which it is removed is important. In the present invention, the following components are used for this purpose. That is, the body of the trommel (15) is formed of a porous mesh formed, coupled in a plurality of assembling form, peeled off by the hammer 23 to the lower end of the support frame 31 for supporting the trommel (15) The lower hopper 38 for receiving the pasted paste is formed to filter the paste falling from the net.

Trommel (15) is cylindrical in shape of the body, the outer portion of the cylindrical is made of a mesh. This is to enhance friction with construction waste and to allow the peeled paste to be released to the outside. In addition, if the assembly is simple and some of the mesh is broken, for the possibility of replacing the pieces to connect and tighten. Then, the support frame 31 supporting the trommel 15 is diagonally formed, and a lower hopper 38 is formed at the lower end of the trommel 15. As described above, since the trommel 15 is formed of a mesh, when the paste is peeled while the trommel 15 rotates, the trommel 15 falls to the bottom of the trommel 15 of the mesh. The coarse aggregate and paste remain inside the trommel 15 to rotate but peel off so that the paste smaller than the net size of the mesh falls to the bottom and falls into the lower hopper 38 shown. Of course, the paste dropped to the lower hopper 38 is separated from the aggregate by the transfer conveyor 33 thereunder.

By the way, the paste falling into the lower hopper 38 is likely to be a paste peeled off by the hammer 23 relatively. It is because it is installed in the front part of the trommel 15. The rear part of the trommel 15 has a configuration similar to the lower hopper 38 in the present invention, which is a guide hopper 37.

That is, at the lower end of the body of the trommel (15), the guide hopper (37) for releasing through the paddle (24) to the side of the lower hopper (38) and receiving thin paste falling from the net body to the lower conveying conveyor (34). ). Through the hammer 23, the larger construction waste is blown and the aggregate and the paste are swept down to the rear part of the trommel 15 in a state where the paste is peeled off. At this time, the paste exited from the mesh of the trommel 15 to the lower hopper 38 described above is discharged to ride the conveying conveyor (39). However, larger pastes or aggregates will fall to the deeper bottom of the trommel 15 compared to the net size of the net. At this time, as the paddle 24, which is the paste separator 30, rotates, friction with the construction waste is made, and the smaller paste is peeled off. The peeled paste falls into a separate guide hopper 38 installed at the rear side of the lower hopper 38, and is discharged through the transfer conveyor 39 installed at the lower end of the guide hopper 38. That is, the present invention is a circulating aggregate production device to separate the construction waste into aggregate and paste to reuse the aggregate.

In general, the construction waste, whose volume is significantly destroyed through the crusher or the like, is introduced into the hopper 13 of the aggregate input unit 10, and the injected construction waste passes through the guide panel 14 through the belt and paste separation device ( 30 is entered into the trommel (15). Entered construction waste causes friction with the inside of the trommel 15, and after the first stage separation operation in which the paste is peeled off, the paste is secondarily peeled through friction with the hammer 23 rotating inside the trommel 15. . At this time, the paste peeled off by the trommel 15 and the hammer 23 falls to the lower hopper 38 at the bottom, and is moved again by the transfer conveyor 39 to be separated from the aggregate. The construction waste coming into the rotating space of the paddle installed at the rear end of the hammer 23 is separated by the friction with the paddle 24 again, wherein the paste to be separated is finer than the paste separated by the hammer 23. It must be This paste is dropped into the guide hopper 37 at the bottom of the trommel 15 and moves to the transport conveyor 34 at the bottom. The paste moving on the conveying conveyor 34 may be separately managed to find disposal or reuse. As a result, the circulating aggregate production apparatus of the present invention is characterized in that it automatically performs all the steps of crushing and conveying construction waste, peeling paste from the aggregate, and separating and removing the peeled paste.

Then look at an embodiment that can effectively perform the function in this circulation aggregate production apparatus of the present invention.

One of them, the lower side of the trommel 15 of the present invention is installed inclined, the connection between the support frame 31 for supporting the trommel 15 and the main frame 35 at the lower end thereof. By combining with the screw (33) so that the level can be raised and lowered, by installing the transfer conveyor 39 to the lower end of the lower hopper 38 to remove the peeled paste.

In detail, the cylindrical trommel 15 is inclined to the support frame 31 so that the construction waste can be moved from the inlet side to the rear side while rotating. However, in doing this, there is a possibility that the amount of recycled aggregate produced varies depending on the nature of the construction waste and the size of the particles. In order to solve this problem, in the present invention, it is possible to control the belt interlocking speed of the conveying means 12 of the aggregate input part 10 described above with an inverter and adjust the inclination angle of the trommel 15 so as to keep pace with this. To help.

When the inclination of the trommel 15 is high, more circulating aggregate production can be obtained. In the present invention, by simply coupling the screw 33 between the main frame 35 and the support frame 31 so that one side of the trommel 15 can be raised and lowered. In the illustrated figure, when the jet screw 33 is rotated by installing the jet screw 33 on the rear side of the trommel 15, the trommel 15 using the principle of changing the level of the rear of the trommel 15 is different. Adjusting the tilt angle of). However, the trommel 15 of the present invention may be provided with both the front and rear jet screw 33, or may be provided only in the front.

Next, the second means for improving the function is to periodically remove the phenomenon of clogging of the trommel 15 by providing an air hammer 23 in the trommel 15 of the present invention. Trommel (15) is a form of a combination of a number of network. As the paste escapes, it may block the net and cause the paste to be discharged. In order to solve this problem, in the present invention, the air hammer is fixed to one side of the trommel 15 to periodically hit the network to block the phenomenon of clogging. It is always considered that the net can be discharged to the lower hopper 38 or the guide hopper 37 of the appropriate volume paste.

The third means for improving the function is interlocked by the hydraulic cylinder 41 on the outside of the trommel (15), the trommel cover to protect the trommel (15) and blocking the scattering of dust blocking The means 40 are installed. The inside of the trommel 15 always performs the action that the paste is peeled off. Dust may blow, and noise may spread around. In addition, the trommel (15) may be corroded by rain or snow because it is left in the open air. In order to eliminate this problem, the present invention forms a trommel cover 42 that is operated by the hydraulic cylinder 41 so that the trommel 15 can be wrapped when necessary. By wrapping the outer portion of the trommel 15 as shown in Figures 2 and 5, to achieve the above object.

As a means for improving the next fourth function, a plurality of rollers 32 are supported at the bottom of the trommel 15 for accurate and stable rotation of the trommel 15. Trommel 15, which must continuously rotate at a tapered angle, with strong strikes and long rotations, is supported by rollers 32 at the bottom. As shown in FIGS. 5 and 7, two rollers 32 each formed in the front-rear direction at the lower end of the outer circumferential surface of the roller 32 allow the rotation of the trommel 15 to be maintained evenly. It also acts as a means to enhance durability to prevent the trommel 15 from breaking even in a long rotation.
