Description

Technical Field

[0001] The invention relates to the technical field of waste plastic recycling, in particular to a sorting device for recycling and regenerating waste ground film. Background Art

[0002] Agricultural mulch film is a plastic film widely used in the agricultural field. It is mainly used to cover farmland to increase ground temperature, maintain soil moisture, promote seed germination and rapid growth of seedlings, and inhibit weed growth. At present, my country ranks first in the world in the development of mulch film technology and the use of mulch film for covering. With the continuous promotion and application of agricultural mulch film over the years, more and more mulch films remain in farmland. Under natural conditions, they cannot be degraded for hundreds of years, seriously polluting the environment. And because agricultural mulch film is an important material for achieving "reduction, reuse, and resource utilization" in modern economic development, its production and processing are pollution-free, low-consumption, and high-efficiency processes. Most agricultural mulch films mixed with impurities such as sediment and straw can be reused after being shredded and sorted and recycled. They are typical resource-saving materials. Therefore, the shredding, sorting, recycling, and reuse of agricultural mulch film are of great practical significance.

[0003] The existing sorting equipment for recycling and regenerating waste mulch generally adopts the form of wind sorting, and sorts the mulch according to the different specific gravity of the mulch and sand. Therefore, external cyclone separators and other equipment are required, which leads to a large footprint of the equipment, a complex structure and high production cost. Secondly, during the sorting process, some dust will be mixed in the mulch, resulting in the mulch after sorting still containing debris, affecting subsequent recycling and utilization. The mulch is discharged to the equipment. In addition, when the mulch after sorting is collected, due to its light weight, the mulch will float in the environment with the wind, making it inconvenient to collect the mulch.

DETAILED DESCRIPTION

[0035] In order to more clearly illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the present invention. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the present invention.

[0036] according to Figure 1-14 As shown, a sorting equipment for recycling and regenerating waste mulch film comprises a frame 1, on which a sorting device is arranged, the sorting device comprises a scattering barrel 2, in which a roller 4 is movably installed, on which a plurality of groups of blades 41 are distributed in a spiral array, the blades 41 are used to transport and scatter the material, and at the same time generate wind force to push the mulch film, the discharge end of the scattering barrel 2 is connected with a secondary screening device, the secondary screening device comprises a discharge pipe 10, the side of the discharge pipe 10 is connected with a discharge pipe 11, a mulch film collecting mechanism is arranged at the connection between the discharge pipe 11 and the discharge pipe 10, the mulch film collecting mechanism is used to transport the mulch film in the discharge pipe 10 to the discharge pipe 11, and a blade roller 115 is movably installed at the discharge end of the discharge pipe 11.

[0037] In the above specific embodiment, the ground film to be sorted is put into the breaking up drum 2, and the ground film is mixed with soil and straw. During sorting, the blades 41 are driven to rotate by the rotating rod 4, and the materials are scattered by the blades 41 to separate the ground film. The blades 41 will also generate wind force when rotating, so as to blow the scattered and separated ground film to the discharge end of the breaking up drum 2, and then the ground film enters the discharge pipe 10, and is transported to the discharge pipe 11 by the ground film collecting mechanism. The ground film collecting mechanism separates the dust from the ground film when transporting the ground film, and further reduces the debris mixed in the ground film, which is useful for subsequent recycling. After entering the discharge pipe 11, the ground film falls between the blades of the blade roller 115, and is discharged from the discharge pipe 11 by the rotation of the blade roller 115, wherein the blade roller 115 has a wind-blocking effect, thereby preventing the ground film from floating in the environment with the wind, thereby facilitating the work of collecting the ground film.

[0038] The present embodiment provides a sorting device for recycling and regenerating waste mulch film. The material to be sorted is fed into the scattering drum 2 via the feed port 21 through a conveying device such as an elevator. The first motor 5 is started, and the first motor 5 drives the second pulley 51 to rotate. The power of the second pulley 51 is transmitted to the first pulley 43 through the first belt 52, thereby driving the rotating rod 4 to rotate. The rotating rod 4 rotates about 1000 times under the drive of the first motor 5. The material at the feed port 21 is pushed to the discharge end of the scattering drum 2 through the spiral feeding sheet 42. The material contacts the blade 41 during the conveying process. The material is quickly scattered and separated at the high speed of the blade 41. Since the weight of the mulch film is relatively light, the separated mulch film is blown to the discharge port 22 by the wind force generated by the blade 41. The specific technical scheme is as follows:

[0039] like Figure 1-6 As shown, a feed port 21 is provided at the left end of the scattering cylinder 2, a discharge port 22 is provided at the end of the scattering cylinder 2 away from the feed port 21, the roller 4 is rotatably installed in the scattering cylinder 2 through a bearing seat, the axis of the roller 4 is the same as the axis of the scattering cylinder 2, a spiral feeding sheet 42 is provided at the end of the roller 4 close to the feed port 21, a first pulley 43 is fixedly installed at the left end of the roller 4, a first motor 5 for driving the roller 4 to rotate is fixedly installed on the frame 1, a second pulley 51 is fixedly installed on the power output shaft of the first motor 5, and the second pulley 51 and the first pulley 43 are connected to each other through a first belt 52.

[0040] The present embodiment provides a sorting device for recycling and regenerating waste mulch film. The soil and straw separated from the mulch film in the scattering barrel 2 fall onto the soil filter plate 3 at the bottom of the scattering barrel 2 and enter the feed box 6 through the mesh 31. The soil and straw slide along the side wall of the feed box 6 to the bottom end of the feed box 6. The feeder 7 is driven to rotate by the second motor 8, and the material at the bottom end is pushed to the middle of the feed box 6 by the feeder 7, and discharged from the slag discharge port 61 to the outside of the equipment for collection. After that, the collected soil and straw are re-landfilled into the field for reuse to avoid waste of resources. The specific technical solution is as follows.

[0041] like Figure 1-5 As shown, a soil filter plate 3 is fixedly installed at the bottom of the scattering barrel 2 by bolts. The soil filter plate 3 is a semicircular ring structure. The inner diameter of the soil filter plate 3 is equal to the inner diameter of the scattering barrel 2. A plurality of groups of mesh holes 31 are opened on the soil filter plate 3. The mesh holes 31 are evenly distributed in an array on the soil filter plate 3. The mesh holes 31 are elongated waist-shaped hole structures. The ground film is a sheet structure with a large area, and its width is greater than the width of the mesh holes 31. Therefore, the mesh holes 31 on the soil filter plate 3 are only for soil and straw to pass through, and the ground film will be isolated in the scattering barrel 2.

[0042] A feed box 6 is fixedly mounted on the top of the frame 1, and the cross-section of the feed box 6 is a bucket-shaped structure that is wide at the top and narrow at the bottom. A breaking barrel 2 is fixedly mounted on the top of the feed box 6 by bolts, and the soil filter plate 3 is located inside the feed box 6. A feeder 7 is rotatably mounted on the lower end of the feed box 6 through a bearing seat. The feeder 7 preferably adopts an auger with coaxial reverse blades, and a third pulley 71 is fixedly mounted on the left end of the feeder 7. A second motor 8 is fixedly mounted on the frame 1, and a fourth pulley 81 is fixedly mounted on the power output shaft of the second motor 8. The third pulley 71 and the fourth pulley 81 are connected to each other by a second belt 82. The bottom end of the feed box 6 is an arc structure, and a slag discharge port 61 is opened in the middle of the bottom end of the feed box 6.

[0043] This embodiment provides a sorting device for recycling and regenerating waste mulch film. In order to prevent the wind in the scattering cylinder 2 from being blown out from the slag discharge port 61, a wind shield 9 is installed above the slag discharge port 61, so that the wind cannot directly act on the slag discharge port 61, thereby preventing the wind from blowing out from the slag discharge port 61 and causing dust to fly. The specific technical solution is as follows:

[0044] like Figure 5 As shown, a wind shield 9 is arranged between the feeder 7 and the soil filter plate 3. The wind shield 9 is an arc-shaped structure. The wind shield 9 is fixedly installed in the middle of the front and rear side walls of the feed box 6. The width of the wind shield 9 is slightly larger than the width of the slag discharge port 61.

[0045] The present embodiment provides a sorting device for recycling and regenerating waste mulch film. The sorted mulch film enters the discharge pipe 10 through the discharge port 22 of the scattering barrel 2. An air guide slope 101 is provided at the corner of the discharge pipe 10. The air flow in the discharge pipe 10 is guided by the air guide slope 101 to avoid backflow or eddy current in the discharge pipe 10, thereby ensuring smooth air circulation in the discharge pipe 10. The mulch film enters the interior of the discharge pipe 10 from the air inlet 102 under the push of wind. When the mulch film moves to the discharge port 104, it is transported to the discharge pipe 11 under the action of the mulch film collecting mechanism, and the collecting cavity 1 The blade roller 115 inside 14 makes the inside of the discharge pipe 11 in a negative pressure state, so that the dust is discharged from the air outlet 103 along with the air. The air outlet 103 is connected to the dust removal equipment to prevent dust from polluting the environment. After entering the discharge pipe 11, the ground film falls between the blade rollers 115 under the action of gravity. The blade roller 115 is driven to rotate by the third motor 116. The blade roller 115 transfers the ground film to the drop port 117. The ground film falls from the drop port 117 to the outside of the equipment. A collection box and other collection equipment are provided below the drop port 117 to collect the ground film. The specific technical scheme is as follows:

[0047] The present embodiment provides a sorting device for recycling and regenerating waste mulch film. The first implementation method of the mulch film collection mechanism is that the push plate 13 and the baffle plate 14 cooperate with the feed port 113 to isolate the internal space of the discharge pipe 10 and the discharge pipe 11. The mulch film in the discharge pipe 10 is blocked at the feed port 113 by the partition 171, and the dust passes through the gap between the partitions 171 and is discharged from the air outlet 103, thereby separating the mulch film and the dust. The hydraulic rod 15 is periodically started, and the connecting rod 12 is pushed to move by the driving plate 16, so that the mulch film on the partition 171 is pushed into the discharge pipe 11 through the push plate 13. The specific technical scheme is as follows:

[0048] like Figure 9-11 As shown, the ground film collecting mechanism includes a connecting rod 12, which is slidably installed on the left and right side walls of the discharge pipe 11, and a pushing plate 13 is fixedly installed in the middle of the connecting rod 12, and baffle plates 14 are arranged on the left and right sides of the pushing plate 13, and the baffle plates 14 are fixedly installed on the connecting rod 12, and the distance between the pushing plate 13 and the baffle plate 14 is equal to the width of the discharge pipe 10, and the pushing plate 13 is installed in the discharge port 104, and the sizes of the pushing plate 13 and the baffle plate 14 are the same as the size of the discharge port 104.

[0049] A hydraulic rod 15 is fixedly installed on the front side wall of the discharge pipe 11, and the output end of the hydraulic rod 15 is fixedly connected to a driving plate 16. The driving plate 16 is a "C"-shaped structure, and both ends of the driving plate 16 are fixedly connected to both ends of the connecting rod 12. The power of the hydraulic rod 15 is transmitted to the connecting rod 12 through the driving plate 16, and the connecting rod 12 is limited by the driving plate 16 at the same time.

[0050] A fixed frame 17 is fixedly installed at the bottom end of the discharge port 104, and a plurality of groups of partitions 171 are arranged in the fixed frame 17. The plurality of groups of partitions 171 are arranged in an array perpendicular to the moving direction of the push plate 13.

[0051] The present embodiment provides a sorting device for recycling and regenerating waste mulch film. The second implementation method of the mulch film collection mechanism is that the feed roller 18 crosses the discharge pipe 10. When the mulch film hits the feed roller 18, it will slide onto the mulch film filter 19 at the bottom of the feed roller 18. The dust in the air passes through the mulch film filter 19 and enters the air outlet 103. The mulch film is retained on the mulch film filter 19. The feed roller 18 is driven to rotate by the fourth motor 182. The mulch film on the mulch film filter 19 is pushed into the first discharge box 111 and the second discharge box 112 under the action of the spiral conveying sheet 181. The specific technical scheme is as follows:
