Technical Field

[0001] The invention relates to the technical field of crushed stone asphalt waste sorting, in particular to a crushed stone asphalt mixed waste sorting device. Background Art

[0002] Crushed asphalt is widely used for paving roads, squares, parking lots, etc. During repair or reconstruction, the taken out waste crushed asphalt needs to be crushed and sorted, and then used as part of the raw materials and then produced into crushed asphalt for paving together with other raw materials. Since the weights of different materials in the crushed waste crushed asphalt are different, wet separation is often used for sorting. Since the crushed waste crushed asphalt is mixed with a lot of dust or other lighter impurities (leaves, dead grass, etc.), it is not conducive to ensuring the effect of wet separation. Once the crushed waste crushed asphalt is accumulated during the sorting process, the lighter part is accumulated inside, which is not conducive to wet separation and reduces the efficiency of wet separation.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0017] See also Figure 1-13 , the present invention provides a technical solution: A crushed stone asphalt mixed waste sorting device comprises a support assembly, wherein the front and rear parts of the upper end of the support assembly are respectively provided with a conveying trough 11 and a washing trough 19; The support assembly includes a base 1, a stand 3 provided at the rear of the upper end of the base 1, a stand plate 2 provided at the middle of the upper end of the base 1, and four groups of columns 28 provided at the front of the upper end of the base 1; The rear of the conveying trough 11 extends and is fixed in the stand 3, and a feeding funnel box 4 is provided on the top of the stand 3. The upper part of the vertical plate 2 is fixed to the side of the conveying trough 11, and the tops of the four groups of columns 28 are connected to the four corners of the bottom of the washing tank 19.

[0018] A discharge pipe is provided at the bottom of the feeding hopper box 4, the bottom of the discharge pipe extends into the vertical frame 3, and the bottom of the discharge pipe is located above the rear part of the conveyor belt 9. In this way, after the crushed asphalt mixed waste is fed into the feeding hopper box 4, under the action of gravity, the crushed asphalt mixed waste falls through the discharge pipe to the upper end of the rear part of the conveyor belt 9. The crushed asphalt mixed waste is transported forward by the rotation of the conveyor belt 9 and the conveyor belt 9.

[0019] A waste discharge trough 20 is provided at the top of the front end of the washing tank 19; A conveyor belt assembly driven by a motor 10 is provided inside the conveyor trough 11, so that the conveyor belt assembly conveys the crushed stone asphalt mixed waste to a uniform distribution assembly 15 provided inside the front end of the conveyor trough 11; The conveyor belt assembly includes a driving roller 12 and a driven roller 47 movably connected at the front and rear ends of the conveyor trough 11, and a conveyor belt 9 connected between the driving roller 12 and the driven roller 47; The conveying trough 11 is also movably connected with a plurality of groups of intermediate support rollers 48 distributed at equal intervals. The intermediate support rollers 48 are located inside the conveying belt 9. Such a setting can support the conveying belt 9 through the intermediate support rollers 48, prevent the conveying belt 9 from fluctuating when rotating, and extend the service life of the conveying belt 9. Several groups of limiting protrusion plates 5 are evenly spaced on the outer surface of the conveyor belt 9, so that the crushed stone asphalt mixed waste can fall between adjacent limiting protrusion plates 5 through the discharge pipe at the bottom of the feeding funnel box 4, and when the rotation speed of the conveyor belt 9 is constant, the crushed stone asphalt mixed waste can be evenly distributed between adjacent limiting protrusion plates 5.

[0020] The motor 10 is fixed on a mounting frame 25 on the front right side of the conveying trough 11 , and the motor shaft at the output end of the motor 10 passes through the mounting frame 25 and the right side wall of the conveying trough 11 and is connected to the right end of the active roller 12 .

[0021] The motor 10 is controlled by PLC, and the model of the motor 10 is Mitsubishi HC-SF202B motor, Mitsubishi HG-SR702B motor, Mitsubishi HK-KT7M3UWBJ or other models that meet the use requirements.

[0022] The motor 10 works, so that the motor shaft drives the conveyor belt 9 to rotate through the active roller 12, so as to transport the crushed stone asphalt mixed waste material on the upper end of the conveyor belt 9 forward, so that the crushed stone asphalt mixed waste material falls into the material receiving chute 152 on the top of the material distribution seat 151.

[0023] The motor 10 drives the air blowing assembly to blow air toward the crushed stone asphalt mixed waste material on the conveyor belt assembly, and blows the impurities mixed in the crushed stone asphalt mixed waste material into the impurity collecting assembly on the conveying trough 11; The air blowing assembly includes a circular air collecting box 6 fixed on the right side wall of the conveying trough 11, a fan 50 fixed by a fan shaft inside the circular air collecting box 6, a first pulley 30 fixed after the right end of the fan shaft extends out of the circular air collecting box 6, a second pulley 33 fixed on the motor shaft, a hollow air guide box 7 connected to the left side wall of the upper part of the circular air collecting box 6, and a plurality of groups of air blowing pipes 49 connected to the bottom of the hollow air guide box 7 and distributed at equal intervals; A belt 31 is connected between the first pulley 30 and the second pulley 33 , and an air intake slot 32 is provided on the right end surface of the circular air collecting box 6 .

[0024] The diameter of the second pulley 33 is greater than that of the first pulley 30, so that when the motor shaft rotates, the belt 31 and the first pulley 30 can drive the fan shaft and the fan blades 50 on the fan shaft to rotate at high speed, and the high-speed rotation of the fan blades 50 forms a negative pressure in the circular air collecting box 6, thereby sucking the outside air into the circular air collecting box 6 through the air inlet slots 32, and pressing the air in the circular air collecting box 6 into the hollow air guide box 7, and finally making the air in the hollow air guide box 7 blown out to the upper end surface of the conveyor belt 9 through the blowing pipe 49; At this time, the air blown out through the air blowing pipe 49 blows up the dust or other light impurities mixed in the crushed stone asphalt mixed waste, so that the dust or other light impurities fall into the box body 81.

[0025] like Fig.11 As shown, the impurity collection assembly includes a reinforced top plate 24 connected to the upper end of the middle portion of the conveying trough 11 and a collection box 8 connected to the bottom of the front and rear ends of the reinforced top plate 24; The hollow air guide box 7 is fixed on the top of the reinforced top plate 24, and the bottom of the air blowing pipe 49 passes through the reinforced top plate 24 and is located between the front and rear groups of collecting boxes 8; The collecting box 8 includes a box body 81, a U-shaped card seat 83 provided on the top of the box body 81, and an inclined baffle 82 provided inside the box body 81. The U-shaped card seat 83 is used to be clamped on the reinforcing top plate 24, so that the box body 81 can be detachably installed. When the box body 81 is filled with dust or other light impurities, the box body 81 can be quickly disassembled and replaced with a new box body 81. Several groups of inclined baffles 82 arranged at equal intervals inside the box body 81 can be used to block dust or other light impurities, preventing dust or other light impurities from accumulating at the bottom of the box body 81 and then overflowing.

[0026] The motor 10 drives the uniform distribution assembly 15 to move back and forth through the gear connecting rod assembly, so that the uniform distribution assembly 15 conveys the crushed stone asphalt mixed waste to the screen 23 in the water washing tank 19 through the guide trough 17 at the front end of the conveying trough 11; like Figure 5 , 7 As shown in Figure 8, the gear connecting rod assembly includes a first bevel gear 34 fixed on the motor shaft, a second bevel gear 35 connected to the mounting frame 25 by a vertical shaft 44, a turntable 36 connected after the bottom of the vertical shaft 44 passes through the mounting frame 25, a connecting rod 37 connected to the bottom of the turntable 36 by a first connecting pin 46, an L-shaped seat 39 connected to the other end of the connecting rod 37 by a second connecting pin 38, a light rod 41 fixed on the L-shaped seat 39, and a vertical limit column 42 fixed to the other end of the light rod 41; The first bevel gear 34 is meshed with the second bevel gear 35; the size of the first bevel gear 34 is larger than the size of the second bevel gear 35; A limiting slot 43 is provided at the front lower end of the conveying slot 11 , the bottom of the vertical limiting column 42 extends out of the limiting slot 43 , and a limiting seat 40 is further provided on the right side of the limiting slot 43 , and the polished rod 41 passes through the limiting seat 40 .

[0027] The motor shaft drives the second bevel gear 35, the vertical shaft 44 and the rotating disk 36 to rotate through the first bevel gear 34; The rotating disk 36 drives the polished rod 41 to reciprocate left and right through the connecting rod 37 and the L-shaped seat 39, so that the polished rod 41 drives the vertical limiting column 42 to reciprocate left and right in the limiting through groove 43; Thus, the vertical limiting column 42 drives the cloth seat 151 to move back and forth left and right through the connecting plate 155.

[0028] A water inlet assembly is also provided on the top of the guide trough 17 . Clean water introduced by the water inlet assembly is mixed with the crushed stone asphalt mixed waste material and then enters the washing trough 19 . The water inlet assembly is located above the front of the uniform distribution assembly 15 .

[0029] The water inlet assembly includes a water inlet pipe 16 fixed on the top of the material guide trough 17 and a plurality of groups of water spray pipes 29 connected at equal intervals at the bottom of the water inlet pipe 16 .

[0030] The water outlet pipe of the water pump is connected to one end of the water inlet pipe 16. The water pump is controlled by PLC. The water pump adopts IS series clean water pump, ISG series vertical clean water pump, SG type clean water pipeline pump or other models that meet the use requirements; The water pump works to introduce clean water in the water tank into the water inlet pipe 16, and sprays it into the guide trough 17 through the water spray pipe 29, and mixes with the crushed stone asphalt mixed waste material that slides into the guide trough 17 through the material receiving chute 152; The muddy water mixed with the dust in the crushed asphalt mixed waste material falls through the liquid leakage channel (not shown in the figure) on the guide trough 17, and then the crushed asphalt mixed waste material falls onto the screen 23 through the guide trough 17.

[0031] The uniform material distribution component 15 includes a material distribution seat 151 disposed inside the front end of the conveying trough 11, a connecting plate 155 disposed in the center of the rear end of the bottom of the material distribution seat 151, and a plurality of groups of equally spaced material receiving chute 152 disposed on the top of the material distribution seat 151; Both ends of the cloth seat 151 extend out through the limiting slots 51 on the side wall of the conveying trough 11; The top of the vertical limit column 42 is fixed to the bottom of the rear end of the connecting plate 155; A triangular slope 153 is provided at the top between adjacent material receiving chutes 152 , and a material blocking plate 154 is connected between the triangular slope 153 and the rear end of the material receiving chutes 152 .

[0032] When the material distributing seat 151 reciprocates left and right, the crushed asphalt mixed waste material transported and dropped by the front end of the conveyor belt 9 can be uniformly introduced into the material receiving chute 152, and when the crushed asphalt mixed waste material slides down through the material receiving chute 152, the crushed asphalt mixed waste material can be uniformly introduced into the material guide trough 17, and then uniformly dropped onto the screen 23; It can prevent the crushed asphalt mixed waste from piling up, and prevent the lighter parts of the crushed asphalt mixed waste from piling up inside, so that the lighter parts of the crushed asphalt mixed waste can quickly float on the surface of the clean water in the washing tank 19.

[0033] A rubber telescopic box 27 is provided in the center of the bottom of the washing tank 19. When the uniform distribution assembly 15 reciprocates left and right, the rubber telescopic box 27 is contracted up and down through the piston air intake lifting assembly, so that the rubber telescopic box 27 reciprocates to adjust the height of the clean water in the washing tank 19, so that the waste floating on the surface of the clean water is discharged from the washing tank 19.

[0034] The piston air intake lifting assembly includes a lifting plate 18 fixed at the bottom of a rubber telescopic box 27, a rubber bellows 26 fixed at the bottom of the lifting plate 18, a piston 156 fixed at the left end of a cloth seat 151 by a piston rod 157, a cylinder body 13 fixed at the left side of a conveying trough 11, and an air guide pipe 14 connected between the left end of the cylinder body 13 and the bottom side of the rubber bellows 26; The piston 156 is slidably connected in the cylinder 13; The four hanging corners of the lifting plate 18 are provided with sleeve tubes 21 sleeved on the pillars 28, so that when the lifting plate 18 moves up and down, it can ensure that the lifting plate 18 moves up and down smoothly and stably, so that the lifting plate 18 is always in a vertical state; The column 28 is also sleeved with a buffer spring 22, and the buffer spring 22 is located between the base 1 and the sleeve 21. Such a setting can achieve buffering of the lifting plate 18 when the lifting plate 18 moves downward; After the piston 156 moves to the left in the cylinder 13, the air in the cylinder 13 is pressed into the rubber bellows 26 through the air guide pipe 14. After the rubber bellows 26 expands, the lifting plate 18 moves upward. At this time, the rubber telescopic box 27 is gradually compressed, and the clean water inside the rubber telescopic box 27 gradually enters the water washing tank 19, so that the height of the clean water above the screen 23 is raised until the clean water overflows the connection between the water washing tank 19 and the waste discharge tank 20, thereby discharging the waste floating on the surface of the clean water from the water washing tank 19; After the piston 156 moves rightward in the cylinder body 13, the air in the rubber bellows 26 is sucked back into the cylinder body 13 through the air guide pipe 14. At this time, the rubber bellows 26 retracts and the lifting plate 18 moves downward. At this time, part of the clean water in the water washing tank 19 enters the rubber telescopic box 27 again, and the water level in the water washing tank 19 drops. Then, when the cloth seat 151 moves back and forth left and right, the piston rod 157 thereon drives the piston 156 to move back and forth left and right in the cylinder body 13, so that the height of the clean water surface in the washing tank 19 continues to rise and fall, so that the waste floating on the clean water surface can be quickly discharged from the washing tank 19 through the waste discharge tank 20.

[0035] The heavier part of the crushed stone asphalt mixed waste material remains on the screen 23, thereby achieving the separation of the crushed stone asphalt mixed waste material.
