Description

The parts with recycling value include a base, a tower, a generator part and a fan blade. When the fan blade is recycled, the fan blade needs to be broken due to its large size. The fan blade is usually cut into blocks or pieces first, and then a pulverizer is used to break the fan blade. However, it is difficult to break the fan blade into small particles, which brings difficulties to the subsequent separation of light material and heavy material. Even if the breaking time is prolonged, the pulverizer is easily damaged, and the working efficiency is not high.

The light material separated is basically blocky, fibrous and the like with small size, but the light material is mixed with metal. The light material needs to be further separated.

[0050] In some embodiments, as shown in Figure 2 The belt conveyor includes a support, a rack 103, a belt 104, an upper roller set 102 and a lower roller set 106. The rack 103 is inclinedly arranged.

Three belt conveyors are provided, which are a first-stage belt conveyor 1, a second-stage belt conveyor 3 and a third-stage belt conveyor 5. The first-stage belt conveyor 1, the second-stage belt conveyor 3 and the third-stage belt conveyor 5 have the same structure.

[0051] The embodiment of the present application can prevent the material from sliding down during the upward transmission by arranging the partitions on the belt 104 of the belt conveyor. The material can be prevented from falling from the side of the belt 104 by arranging the guard plates 101 on the two sides of the rack 103.

[0052] Further, the height of the guard plate 101 is higher than that of the partition.

[0053] In some embodiments, as shown in Figure 2As shown, the support of each belt conveyor respectively comprises a front support 108, a middle support 107 and a rear support 105, the front support 108 is supported at the front of the frame 103, the middle support 107 is supported at the middle of the frame 103, and the rear support 105 is supported at the rear of the frame, the height of the front support 108, the middle support 107 and the rear support 105 decreases in turn, and the bottom of the front support 108, the middle support 107 and the rear support 105 is respectively connected with a lifting mechanism to adjust the inclination angle of the frame 103.

[0055] The feeding hopper 201 is located above the feeding port of the shredding chamber 204, and the discharging hopper 203 is located below the discharging port of the shredding chamber 204, and the shredder is provided with two, which are a first shredder 2 and a second shredder 4, the first shredder 2 is arranged between the first belt conveyor 1 and the second belt conveyor 3, the discharging end of the first belt conveyor 1 is located above the feeding hopper 201 of the first shredder 2, and the feeding end of the second belt conveyor 3 is located below the discharging hopper 203 of the first shredder 2; the second shredder 4 is located between the second belt conveyor 3 and the third belt conveyor 5, the discharging end of the second belt conveyor 3 is located above the feeding hopper 201 of the second shredder 4, and the feeding end of the third belt conveyor 5 is located below the discharging hopper 203 of the second shredder 4, and the width of the cutting teeth of the first shredder 2 is greater than that of the second shredder 4, so that the discharging particle size of the second shredder 4 is smaller than that of the first shredder 2.

[0056] It can be understood that the smaller the width of the cutting teeth is, the smaller the particle size of the obtained particles is.

[0057] Further, the bottom end of the discharging hopper 203 of the shredder is close to the position of the partition plate, which can reduce the dust generated during discharging of the discharging hopper 203.

[0058] In some embodiments, the pulverizer 6 and the shredder are respectively connected with a dust removal device. Dust pollution of the external air can be prevented.

[0059] In some embodiments, as shown in the drawings, Figure 5 , 6As shown, the water separator 10 comprises a water separation tank 1001, a screw conveyor 1003, a light material conveying device 1005 and a poking roller. The water separation tank 1001 has an inlet end and an outlet end in the horizontal direction. The inlet end of the water separation tank 1001 has an inlet opening. The inlet opening of the water separation tank 1001 is connected to the feed hopper 201. The outlet end of the water separation tank 1001 has a heavy material outlet and a light material outlet. The heavy material outlet of the water separation tank 1001 is located at the bottom of the water separation tank 1001. The light material outlet of the water separation tank 1001 is located at the upper portion of the water separation tank 1001. The bottom of the water separation tank 1001 is in a conical structure.

[0060] The screw conveyor 1003 is arranged in the conical structure of the water separation tank 1001. The screw conveyor 1003 has an inlet end and an outlet end in the horizontal direction. The inlet end of the screw conveyor 1003 is located at the inlet end of the water separation tank 1001. The outlet end of the screw conveyor 1003 is located at the heavy material outlet of the water separation tank 1001.

[0061] The light material conveying device 1005 is arranged above the outlet end of the water separation tank 1001 to convey the light material floating on the water surface out of the water separation tank 1001.

[0062] The poking roller comprises a first poking roller 1002 and a second poking roller 1004. The first poking roller 1002 is connected to the water separation tank 1001 near the inlet opening. The outer side of the first poking roller 1002 is uniformly connected with a plurality of poking teeth 10021. The lower portion of the first poking roller 1002 is immersed in the liquid surface of the water separation tank 1001. The bottom of the first poking roller 1002 is close to the bottom of the water separation tank 1001 and leaves a space for the material to pass through. The second poking roller 1004 is arranged between the first poking roller 1002 and the light material conveying device 1005. The outer side of the second poking roller 1004 is uniformly connected with a plurality of poking teeth 10021. The outer diameter of the second poking roller 1004 is smaller than that of the first poking roller 1002.

[0063] The crushed material is fed into the water separation tank 1001 through the inlet opening of the water separation tank 1001. The first poking roller 1002 with a large outer diameter is used to press the crushed material into the bottom of the tank for sufficient soaking. The heavy material sinks into the screw conveyor 1003. The screw conveyor 1003 conveys the heavy material to the heavy material outlet of the water separation tank 1001 and discharges it. The light material floats on the water surface due to its own buoyancy. The light material is poked by the second poking roller 1004 to the light material conveying device 1005, and then discharged out of the light material outlet of the water separation tank 1001. In this way, the heavy material and the light material are separated.

[0064] By setting the water selection pool 1001, screw conveyor 1003, light material conveying device 1005 and the material stirring roller, the heavy material and the light material of the fan blade broken material after air selection can be further separated, and the separation efficiency is improved. By designing the bottom of the water washing pool into a conical bottom structure, the heavy material can be sunk into the conical bottom structure, and can be accurately dropped into the position of the screw conveyor 1003, so as to facilitate the transmission of the heavy material by the screw conveyor 1003, and prevent the heavy material from scattering on the pool bottom and being unable to be timely transmitted.

[0065] Further, the second material stirring roller 1004 is arranged in the horizontal direction with 2.

[0066] Further, the first material stirring roller 1002 and the second material stirring roller 1004 are both driven to rotate counterclockwise by the motor.

[0067] In some embodiments, as shown in Figure 5 、 7 The teeth 10021 are uniformly distributed in several rows along the circumference of the material stirring roller, and each row of teeth 10021 includes a plurality of interconnected teeth 10021, forming a sawtooth structure.

[0068] By designing the teeth 10021 into a sawtooth structure, on the one hand, the sawtooth structure will drive more violent water flow disturbance when stirring the material, which can push the light material to move quickly towards the direction of the light material outlet of the water selection pool 1001, and the sawtooth structure can effectively "bite" the material and drive the material to effectively advance. On the other hand, the sawtooth structure helps to break up the material of the adhered block, prevents the light material from adhering to the heavy material and sinking to the bottom, and improves the separation purity. Thirdly, the sawtooth structure can also prevent long fibers mixed in the material from winding around the material stirring roller. Even if a small amount of fiber is hung on the sawtooth, when the material stirring roller rotates, it will be shaken off due to the "grasping-releasing" action of the sawtooth and the washing action of the water, thereby greatly reducing the occurrence of the shaft wrapping phenomenon, and ensuring the continuous and stable operation of the water selection machine 10.

[0069] In some embodiments, as shown in Figure 8As shown, the light material conveying device 1005 comprises a conveyor belt and a speed reducer 10052, the conveyor belt is arranged obliquely, the conveyor belt has an inlet end and an outlet end, the outlet end of the conveyor belt is higher than the inlet end of the conveyor belt, the inlet end of the conveyor belt is located inside the water tank 1001 and is attached to the liquid surface, the outlet end of the conveyor belt is located outside the water tank 1001, the outlet end of the conveyor belt is connected to a driving wheel, the speed reducer 10052 is located above the water tank 1001, the driving wheel and the speed reducer 10052 are drivingly connected through a first belt 10053, the inlet end of the conveyor belt is connected to a driven wheel, the driving wheel and the driven wheel are drivingly connected through a second belt 10051, a plurality of push plates 10054 are uniformly connected to the second belt 10051, the push plates 10054 located below the second belt 10051 are immersed below the liquid surface of the water tank 1001, so as to discharge the light material floating on the water surface to the outside of the water tank 1001 through the light material outlet of the water tank 1001.

[0070] The embodiment of the present application can push the light material to the light material outlet of the water tank 1001 and discharge it outward by the push plate 10054 of the conveyor belt through the arrangement of the conveyor belt and the speed reducer 10052.

[0071] Further, the speed reducer 10052 drives the second belt 10051 to rotate counterclockwise.

[0072] Further, the angle between the second belt 10051 and the horizontal plane is 10-15°.

[0073] Further, the installation mode of the conveyor belt on the water washing tank is fixedly connected through a mounting piece, which can be various conventional installation modes, which will not be repeated here.

[0074] Further, the push plate 10054 is a rectangular plate, and the length of the push plate 10054 is equal to the width of the second belt 10051. More light material can be discharged outward from the light material outlet of the water tank 1001, avoiding excessive accumulation of light material in the water tank 1001.

[0075] In some embodiments, as shown, Figure 8 As shown, the inner side of the light material outlet of the water tank 1001 is connected to an inner guide plate 1008, the inner guide plate 1008 is inclined downward in the direction away from the light material outlet of the water tank 1001, the inclination angle of the inner guide plate 1008 is equal to the inclination angle of the second belt 10051, the width of the inner guide plate 1008 is equal to the width of the water tank 1001, the outer side of the light material outlet of the water tank 1001 is connected to an outer guide plate 1009, the outer end of the outer guide plate 1009 is inclined downward, and the inlet end of the outer guide plate 1009 and the outlet end of the inner guide plate 1008 are connected at the light material outlet of the water tank 1001.

[0076] By setting the outer guide plate 1009, the light material can be accurately dropped on the designated position, preventing the light material from flowing down along the outer wall of the water-eliminating tank 1001, thereby causing the light material to adhere to the outer wall of the water-eliminating tank 1001.

[0077] Further, the push plate 10054 is in sliding cooperation with the upper surface of the inner guide plate 1008 when pushing the light material, so as to improve the efficiency of discharging the light material.
