New description: [New technical field] This creation is about a bottom slag treatment equipment that can more effectively treat the incinerator bottom slag and maximize the benefits of recycling the incinerator bottom slag. [Prior Art] Garbage disposal is a major environmental issue faced by humans after their high industrialization and urbanization. Among the many waste treatment methods, it is widely used as a waste treatment method to burn and incinerate waste after incineration. The use of incinerators to treat waste has at least several advantages: (1) the volume of waste can be substantially reduced after burning incineration; (2) environmentally hazardous substances contained in waste can be used by Incineration and combustion to remove; (3) The combustion of the incinerator is carried out under controlled conditions, and the exhaust gas is also properly monitored and treated to reduce the harm to the human body; and (4) the bottom slag after combustion can be recycled. Use to improve the economic benefits of waste disposal. Traditionally, bottom slag treatment has been roughly implemented in two ways: direct screening and dry screening. When the bottom slag is collected from the incinerator, the bottom slag is usually sprinkled. On the one hand, the generation of soot during the bottom slag collection operation can be reduced, and on the other hand, the bottom slag can be appropriately cooled. However, this sprinkling operation may cause the water content of the bottom slag component to be indefinite. In the traditional direct screening process, the problem of uncertainty in the water content of the bottom slag is not treated, but the screening operation is directly carried out. Although the treatment method is -3- M382162 cost _ compared? 'but' will also produce some - shortcomings, for example, the bottom-slag odour is too heavy to cause the user to resent; the bottom slag water content is difficult to control and the screening is incomplete, the aggregate particle size can not be distinguished 'causing the sorting efficiency is low, This further limits the disadvantages of the use of the finished product for reuse after processing. In the dry screening treatment, in order to solve the problem of the water content of the bottom slag, the moisture of the bottom slag is completely removed by a fire roasting method. However, this type of treatment has the disadvantage of excessive energy consumption and high processing costs. In view of the above-mentioned problems of the conventional bottom slag treatment, there is a demand in the incinerator bottom slag treatment industry for a bottom slag treatment apparatus capable of solving the disadvantages of the above conventional bottom slag treatment equipment. [New content] One of the purposes of this creation is to provide an incinerator bottom slag treatment equipment, which comprises: a vibrating coarse screening device for preliminary screening of bottom slag into bottom slag larger than the first particle size and less than a bottom particle of a particle size; a drum screening machine for further screening the bottom slag smaller than the first particle size into a bottom slag larger than the second particle size and a bottom slag smaller than the second particle size by a rolling screening method; a screening machine for dividing the bottom slag smaller than the second particle size into a bottom slag larger than the third particle diameter and a bottom slag smaller than the third particle diameter by a water selection method: a sand washing device, which is used to be smaller than the third The sand component in the bottom slag of the particle size is removed; the sediment separating device is used to remove the residual sand component in the bottom slag after the sand washing treatment; the pressure filtering device is used to separate the sediment through the sediment The water in the bottom slag is filtered out to obtain a finished product of the engineering material having a particle diameter smaller than the third particle diameter; and the first electromagnetic sorting device is used for the iron-containing material from the bottom slag larger than the second particle diameter. • 4- M382162 sorted; second electromagnetic sorting device for ferrous materials Sorting from bottom slag larger than the third particle size; eddy current sorting device for separating non-ferrous metal from the bottom slag treated by the second electromagnetic sorting device to obtain a particle size larger than a three-grained engineering finished product; a crushing device for breaking bottom slag larger than the first particle size and larger than the second particle size into a bottom slag smaller than the second particle size for returning to the wet type The screening machine performs a wet selection process; and a transport device for transporting the bottom slag between the devices. According to an embodiment of the invention, the drum screening machine comprises a drum screen having a plurality of screen holes having a plurality of apertures equal to a second particle diameter, wherein a plurality of driving rollers are disposed at two ends of the drum screen for supporting And rotating the drum screen, and wherein the drum screen is disposed at an angle to the horizontal plane such that the remaining end of the drum is higher than the other end. The wet screening machine comprises a screen screen disposed at an angle to the horizontal plane, and a plurality of screen holes having a plurality of apertures equal to a third particle diameter are disposed on the peripheral wall thereof, and the plurality of driving rollers are disposed at the two ends of the drum screen. To support and rotate the drum screen, and a sprinkling unit comprising a water pump and a sprinkling pipe, the water pump extending into the drum screen through one end of the drum screen and having a plurality of sprinkling holes located in the drum screen The sprinkler pipe is on the wall. Other features and advantages of the present invention will become apparent from the following detailed description of the appended claims. [Embodiment] The incinerator bottom slag processing apparatus 1 of the present invention will now be described with reference to the embodiments shown in Figs. 1 to 4 . -5- M382162 Fig. 1 is a schematic view showing a % bottoming slag processing apparatus 1 according to an embodiment of the present invention. The device 1 mainly comprises a vibrating coarse screening machine 10, a drum screening machine 20, an electromagnetic sorting machine 30, a secondary electromagnetic sorting machine 30', a crusher 40, a wet screening machine 50, an eddy current sorting machine 60, The sand washing machine 70, the sediment separator 80, and the filter press 90 and the like. The vibrating coarse screening machine 10 mainly comprises a plane vibrating coarse screen 11 on which a plurality of screen holes are arranged, the diameter of which is approximately equal to the first particle diameter (for example, 75 mm), and is used for the incinerator bottom slag which has been aged. Conduct a preliminary screening. The bottom slag passing through the coarse screen is output from the first discharge port 12 and transported by the conveyor belt to the drum screening machine 20 for secondary screening treatment. However, the bottom slag which fails to pass through the coarse screen is discharged from the second discharge port 14 and sent by the conveyor belt to the crusher 40 for crushing. As shown in Figures 2a and 2b, the drum screening machine 20 mainly comprises a drum screen 21 having a plurality of screen holes 22 formed on its peripheral wall, the diameter of which is approximately equal to the second particle diameter (e.g., 19 mm), and the plurality of driving rollers 23 are disposed. At both ends of the drum screen 21, the drum screen 21 is supported and rotated, and a support frame 24 is used to support the drive roller 23. The drum 21 is disposed at an angle to the horizontal plane such that one end of the drum screen 21 is higher than the other end. The bottom slag from the vibrating coarse screen 1 is fed from the higher end of the drum screen 21 to the drum screen 21 for secondary screening operation. Generally, the size of the sieve holes used in the secondary screening treatment of the bottom slag is small. Therefore, in the conventional flat vibration screening machine, the sieve holes are often clogged, resulting in poor sorting efficiency and frequent shutdown and the like. However, the creative drum screening machine 20 screens the bottom slag in a rolling manner, increases the kinetic energy of the bottom slag treatment, and makes the bottom slag difficult to block the mesh hole, and the -6 - M382162 solves the above-mentioned shortcomings of the conventional vibration design. After screening through the trommel screen 21, the bottom slag of less than 19 m is dropped from the screen hole 2 2 and guided onto the conveyor belt by the collecting plate 26 to be transported to the wet screening machine 50 for fine screening treatment. However, the bottom slag larger than 19 mm falls from the lower end of the drum screen 21 to the other conveyor belt, and is transported to the electromagnetic sorting machine 30 for further processing. The electromagnetic sorting machine 3 is a magnetic force A device that separates a paramagnetic ferrous metal from a non-magnetic nonferrous metal. As shown in FIG. 3, the electromagnetic sorting machine 30 mainly comprises a magnetic force generating device 31 (for example, a permanent magnet or a magnet) for generating a magnetic force, and a transport belt 34 surrounding the magnetic force generating device. The pulleys 32, 33 are driven, wherein the magnetic force generating device 31 is disposed above the terminal end of the conveyor belt that transports the bottom slag to the electromagnetic separator 30, so that the ferrous metal material in the bottom slag is generated by the magnetic force. The magnetic force generated by the device 31 is attracted to the transport belt 34 and transported to the non-magnetic zone (e.g., at the pulley 32). At this point, the ferrous material on the transport belt 34 will fall into the set below the pulley 32. In the port 35, it is collected and transported to the iron-containing material recovery tank. However, the bottom slag after electromagnetic separation is naturally dropped from the end of the conveyor belt that transports the bottom slag to the electromagnetic separator 30 to another conveyor belt located below it, and sent to the crusher 40 for crushing treatment. . The rock crusher 40 performs a crushing operation on the bottom slag from the vibrating coarse screening machine 10 and the electromagnetic sorting machine 30 to disintegrate the bottom slag larger than 19 mm into a bottom slag of less than 19 mm. The bottom slag that has been crushed by the crusher is sent back to M382162 via the conveyor belt to the one-roll-cylinder-screening machine-2 0-IT line-sieving edge-factory the stone machine-40 can be one-to-one - He's two types of crushers available on the market. As shown in FIG. 4, the wet screening machine 50 for wet selection processing mainly comprises a trommel 51 disposed at an angle to the horizontal plane, and a plurality of sieve holes 52 are formed in the peripheral wall thereof, and the diameter thereof is approximately equal to the third. The particle diameter (for example, 4.75 mm), the driving roller 53 is disposed at both ends of the drum screen 51 for supporting and rotating the drum screen 51, and a sprinkling unit includes a water pump 54 and a sprinkling water pipe 55 from the water pump 54 is inserted into the trommel 51 through one end of the trommel 51, and a plurality of sprinkling holes are formed in a portion of the sprinkler 55 in the trommel 51 to uniformly sprinkle the bottom slag in the trommel 51. Perform a wet wash screening operation. After the wet selection treatment, the bottom slag of less than 4.75 mm is conveyed to the sand washing machine 70 and the sediment separator 80 via the conveyor belt to remove the sediment mixed in the bottom slag, and then sent to the filter press 90 for use in the bottom slag. The water is filtered out to obtain a finished product of fine aggregate having a particle size of less than 4.75 mm. The sand washing machine 70, the sediment separator 80, and the filter press 90 used herein may use a conventional conventional sand washing machine, a sediment separator, and a filter press. In addition, after the wet selection process, the bottom is larger than 4.75 mm. The slag is sent to the secondary electromagnetic separator 30' via a conveyor belt to sort the ferrous metal-containing materials. The secondary electromagnetic sorter 30' is similar to the electromagnetic sorter 30, and therefore its construction will not be described again. After sorting by the secondary electromagnetic sorter 30', the iron-free bottom slag is conveyed to the eddy current separator 60 via the conveyor belt for sorting operation of the non-ferrous metal. The eddy current separator 60 is a device that utilizes magnetic field changes to separate non-ferrous metals from other -8-M382162 materials. The eddy current flow path must be parallel to the winding direction of the coil, and the magnetic flux perpendicular to the direction of the alternating magnetic field changes in the opposite direction, so the electric frequency is the same. Objects that sense the excitation of eddy currents must be intrinsic. Using this principle, gold, including aluminum, copper, and stainless steel, can be sorted to increase the recovery price and reduce secondary pollution. The bottom slag after sorting by the eddy current sorter 60 is subjected to φ screening and manual picking of plastic components to obtain a finished product of 4-75 mrn of coarse aggregate. Next, the processing flow of the incineration apparatus of the present creation will be explained with reference to Fig. 1 . First, the slag of the incinerator subjected to the aging treatment is sieved into a bottom slag having a bottom particle diameter larger than the first particle diameter (e.g., 75 mm). Thereafter, the bottom slag smaller than the first particle diameter is subjected to the secondary screening treatment by the separator 20, and the B larger than the first particle diameter is subjected to the disintegration treatment by the crusher 40. a bottom slag that is sent to the drum screening machine 20 that is smaller than the first particle size and that is screened to be larger than the second particle size (e.g., 19 mm). Next, the bottom slag is smaller than the second particle size. Screening machine 50, and bottom slag larger than the second particle size is sent to 30 for magnetically absorbing the iron-containing metal in the bottom slag from the bottom and sent to the ferrous metal recovery tank for recycling and sorting. After the remaining bottom slag larger than the second particle size is sent to the manual sorting method, the plastic material and the non-ferrous metal wire in the bottom slag are flowed straight and communicate with the alternating current frequency and the alternating current conductive conduction from the bottom. The slag is selected and vibrated to have a larger particle size than the bottom slag treatment type coarse sifting machine 1 slag and less than the bottom slag sent to the slag bottom slag, and the bottom slag is sent to the wet electromagnetic sorting machine. The slag is screened. After electromagnetism S 1 0 8 , the material is picked up to -9- M382162 plastic recycling tank and - non-ferrous gold_genus material_recycling tank for recycling. The bottom slag remaining after a selection is sent to the rock crusher 40 for disintegration treatment. The machine 40 disintegrates the bottom slag into a post-feeding screening machine 50 that is smaller than the bottom slag of the second particle size and performs subsequent processing. The bottom slag which is sent to the wet screening machine 50 which is smaller than the second particle size is further screened with a bottom slag larger than the third particle diameter (e.g., 4.75 mm) to the bottom slag of the third particle size. Thereafter, the bottom slag larger than the third particle size is sent to the electromagnetic separator 30', and the bottom slag smaller than the third particle size is sent to the wash 70. The benefits of the wet screening of this creation not only use water to remove the bottom slag, but also remove the components of the bottom slag that are corrosive to the steel bars, chloride ions. At the secondary electromagnetic separator 30', the bottom slag containing more than the third particle size is separated from the bottom slag by magnetic attraction and sent to the containing material recovery tank for recycling. The bottom after electromagnetic sorting is sent to an eddy current sorter 60 where the non-ferrous metal material is sorted from the bottom slag and sent to the non-ferrous metal object by the principle that the object induces eddy currents. The recycling tank is recycled. After the eddy current, the bottom slag is subjected to wind selection, vibration screening and manual picking of waste plastics to obtain coarse aggregates with a particle size larger than three particle diameters (7.45 mm), which are less than the third after being processed by a wet screening machine. The bottom slag of the particle size is subjected to sand washing treatment by the sand washing machine 70, and then sent to the sediment separator 80 for sediment separation treatment, and finally sent to the filter press 90 for pressure filtration treatment, and after the water in the bottom slag is removed, It can be obtained by using the incinerator bottom slag processing equipment of less than three-grained fine aggregates, which is obtained by the incinerator bottom slag processing equipment, which is conductive, whether it is gravel to wet, and as small as the iron slag in the scent of the sand. And was sorted and combined. Delivered to remove the thick bones -10- M382162 finished products or fine aggregates have good carbon ash or natural grit (GP) material with large particle size, low density, high water permeability and high bearing capacity. Similar, suitable for materials such as materials and asphalt additives. The characteristics of the incinerator bottom slag treatment equipment of this creation, the cylinder screening machine to carry out the secondary screening operation of the bottom slag, to increase the kinetic energy of the bottom slag treatment, so that the bottom slag is not easy to block the downtime of the φ sieve hole, so as to greatly Another feature of improving the bottom slag screening is to use wet screening to treat the bottom slag, sprinkle water to remove the odor of the bottom slag, and dissolve the bottom slag medium (eg, chloride ions) to improve the quality of the finished product. Although the incinerator bottoms processing apparatus of the present invention has been illustrated in the preferred embodiment illustrated, this is not limited to the structures described above and illustrated in the drawings and the principles taught in the above disclosure and B different kinds of modifications and changes under the spirit. For example, the above-mentioned devices include the number of various implements in one embodiment, but in order to increase the processing energy or to increase the iron metal, the plurality of various implements can be used in parallel or in series. The specific pore size is exemplified by the addition of a particle size of 75 mm and a second particle size of 19 mm. The second particle g can also be used in order to accommodate various particle sizes. All such possible modifications and variations are within the true scope of the present invention as defined by the scope. Small uniformity, qualitative engineering properties, and coal as one of the road base materials is the use of rolling to use the rolling method to reduce the efficiency of cleaning. This creation corrodes the properties of the steel by uniformizing the bottom slag. In the above reference, the author indicates that the creation is only an operation. In fact, this creation can be illustrated in the example, this creation is illustrated as an example, non-ferrous metal removal rate. Further, although it is described above (for example, the first [4.75 mm), the other particle size, the following patent application -11 - M382162 [Fig. 1] is a schematic diagram of the incinerator bottom slag processing apparatus of the present invention. schematic diagram. 2a and 2b are respectively a schematic front view and a side view of a roller screening machine of the incinerator bottom slag processing apparatus of the present invention.
