1 is a side view of the sorting machine, in which the mixing trash inflow hopper 10 and the rotary rotating device assembly 20-the vertical rotary blades 22 of the rotary couple to the rotary shaft 21 are applied to the rotational force of the rotary drive motor 23. By means of rotational force of the motor 32 driving the rotating plate formed in the center of the rotating plate is formed by rotating the rotating plate assembly (30-flying plate) and the rotating plate assembly (30-scattering action on the friction plate) To the combination of the 40-cover, motor, friction plate, groove and friction plate (the friction surface material of the friction plate is selected from steel plate or rubber plate, and the number of friction grooves varies depending on the shock). Configured combination) and the motor 42 for vibrating the friction plate and the taped partition 52 configured to prevent the mixing of the sorting material and the sorting material to be loaded on the conveyor, a blower 50 for sorting by the difference in flying distance, and a separator plate 51. ), And a conveyor (60-pattern as required), an electromagnet assembly (70), a stepped diaphragm assembly (80), and a permanent compression roller assembly (90).

The rotary waste assembly (20-assembler subassembly) is rotated to supply the mixture to the rotating plate assembly 30 while the mixed waste loaded in the input hopper 10 is rotated. The difference in the friction coefficient by the feeding distance is caused by the frictional resistance of the friction plate, the resistance of the friction groove 41, the resistance of the vibration motor 42, and the mass, density and volume resistance difference of the mixture components. When collected down into the sphere 43, the wind power and the separator of the wind blower 50 of different size (the play and distance of the 51-division plate is adjusted according to the position of the wind and collection port and the amount of the mixture falling) It is sorted by scattering distance due to weight difference. Lighter materials compared to volume receive wind power, are transported over long distances, and metals, nonmetals, stones, wet paper, plastics, PVC chunks, etc. The separation plate 51 is less affected by the wind, and the sorting by the wind is not mixed because there is a taped partition 52, the shape of the partition 52 is taped down on the conveyor 60 The selection will be loaded.

The sorted material is selected by ferrous metal while passing through the electromagnet assembly 70 by conveying the conveyor 60, and then transferred to the stepped vibrating plate assembly 80, the non-flammables of the wet paper and heavy plastics due to the vibration coefficient difference Select from. The mixture not exceeding the separation plate 51 is combined with the conveyor 60, and the magnetic force selection of the electromagnet, the vibration coefficient selection process by the stepped diaphragm, and the water removal process of the permanent magnet compression roller 91 are repeated. The cover is necessary to prevent the garbage from flying out of the sorter due to the scattering caused by vibration or rotational operation, and the wind power of the blower 50 adjusts the strength of the proper wind power in consideration of the weight of the size.

FIG. 2 is a selection example of the friction plate assembly, in which the rotary rotator assembly 20 which rotates vertically when the mixture is introduced into the input hopper 10 supplies the mixture onto the rotating plate, and the rotating plate assembly 30 that rotates horizontally is , The mixture is sprayed on the friction plate assembly 40 in which the friction grooves 41 are formed and vibrated, and fall into the collecting port 43 while showing a difference in the frictional distance and the conveying distance according to the components of the mixture. Stone, metal, wood, glass, etc. have a long transfer distance due to the friction coefficient, and wet paper (large friction coefficient) or vinyl (high air resistance) have a small influence on the rotational force of the rotating plate, so the transfer distance is short. However, small wood, small metal, stone, glass, etc. have a medium transfer distance. When sorting the sorted product passing through the collection port 43 by the wind power, it is important to select the size of the wind power and the position of the separator 51 due to the scattering distance difference according to the characteristics of the material.

FIG. 3 is an overall explanatory view of a sorter, including a friction plate assembly 40, a blower 50, a conveying conveyor 60, an electromagnet assembly 70, a stepped diaphragm assembly 80, and a conveyor 60 for reselection. It consists of an electromagnet assembly 70, a stepped diaphragm assembly 80 and a permanent magnet compression roller assembly 90. Screening by friction coefficient, screening by scattering distance difference, magnetic screening and vibration coefficient screening process is followed by drying. Then, the mixture that does not exceed the separator plate 51 by the wind power of the blower 50 is loaded on the collection conveyor 60 and subjected to magnetic force selection, vibration coefficient selection process, water compression process, and back to the hopper 10 for friction selection. It is the device that went.

Fig. 5 is an explanatory diagram of a stepped vibrating sorter, where a material having a large conveying distance by vibrating falls over the inclined casing guide line 81 to the collection bin 85, and a wet paper or a bundle of vinyl having a low vibration conveying distance is While vibrating along the stepped guide line 81, the structure is moved to the next process. Stepped diaphragm assembly 80 is composed of a sorting plate consisting of a stepping sorting guide line 81 having a vibration motor 82 and a slope. The principle of the vibrator consists of a diaphragm support, a power motor 82, a rotor 83, and a spring 84 connecting the lower support and the upper and lower supports, as shown in the figure. For this reason, vibration is supplied to the sorter by the action of the rotor 83 and the spring 84. When the stepped tilt diaphragm assembly 80 is horizontal, it is difficult to sort by the vibration coefficient, but because of the inclination, a material having a high vibration coefficient may cross the stepped guide line 81, and a non-combustible hard material is collected in the collection.

FIG. 6 is a diagram showing the permanent magnet compression roller assembly. When the permanent magnet compression roller 91 is installed with the transfer conveyor 60 interposed therebetween at the position where the conveyor 60 inclines before the input hopper 10, the conveyor 60 The permanent magnet pressing roller 91 removes the moisture of the selective water having a high moisture content by the force of) and the upper magnetic roller 91 and the lower magnetic roller 91 rotate while pulling each other. The space between the magnet compression roller spaced groove 92 in consideration of the volume of the compressed material in the support spacer spaced portion of the upper roller rotation shaft has a margin as much as the volume of the selected material to be rotated and compressed. And the shaft of the roller is easily supported by the bearing 93 to rotate.

That is, in order to remove the moisture of the mixture (garbage) having a high moisture content in the repetitive screening process, a roller support is formed at an inclined position of the conveyor 60, the transfer unit of the conveyor 60 is positioned in the middle, Install the rotary bearing 93 so that the magnet pressing roller 91 can be easily rotated in the fixed part, and the magnet pressing roller having a separation groove 92 which prevents damage to the device by giving a separation space when the magnet pressing roller 91 is pressed. Description of the roller assembly 90 is

7 is an explanatory view of the rotary assembly, which serves to move the mixture (garbage) to the rotary plate assembly 30 by the power of the drive motor 23 by constructing a vane 22 that performs a vertical rotation operation on the rotary shaft 21. Do it.

FIG. 8 illustrates a rotating vane plate 31 which rotates horizontally in an explanatory view of the rotating plate assembly, and operates to spray mixed rubbish transferred from the rotary assembly 20 by the power motor 32 onto the friction plate assembly 40. Since the direction of rotation is toward the friction plate assembly 40, the mixed waste does not go toward the rotary assembly 20, but there is no problem in the operation of the device even if the rotary assembly 20 goes toward the rotary assembly 20.
