Description

Technical Field

[0001] The invention relates to the field of environmentally friendly processing equipment for waste plastics, and in particular to a long-distance conveying mechanism for waste plastic particles. Background Art

[0002] The waste plastics are melted and granulated after cleaning, and then the plastic particles are bagged after drying. The bagged plastic particles are transported to each wire drawing workshop, and after the bag is cut open, the plastic particles are placed on the hopper, and are melted and drawn into shape in the wire drawing workshop to form new plastics. The above-mentioned waste plastic transportation requires bagging, and the bag is cut when unloading the plastic particles. At the same time, each granulation equipment requires a staff member to bag, and each wire drawing equipment requires a person to cut the bag and unload, which requires more staff, increases costs, and the efficiency of transportation is relatively low, and a large number of bags are wasted.

[0003] Since granulation and melt molding are carried out in different workshops, mechanical or pneumatic conveying can be used for long-distance transportation. The conveying efficiency of plastic particles is relatively low when mechanical conveying is used. When pneumatic conveying is used to transport large plastic particles, it is easy to wear against the inner wall of the pipeline during long-distance transportation. The longer the transportation distance, the more serious the wear. The elbows, valves and other components in the conveying pipeline will accelerate wear due to the impact of particles. Therefore, the conveying pipeline needs to be inspected frequently and replaced at the location where severe wear occurs. The machine needs to be shut down during replacement and inspection, which will affect transportation and the maintenance cost is relatively high. Summary of the invention

[0029] The present invention will now be further described with reference to the accompanying drawings.

[0030] like Figure 1-12 As shown, a long-distance conveying mechanism for waste plastic particles includes a temporary storage tube 1, a collecting mechanism 2, a lifting mechanism 7, a pneumatic conveying mechanism 9 and a material dividing mechanism 32. A plurality of temporary storage tubes 1 are arranged in a granulation workshop 42, and each temporary storage tube 1 is connected to each granulation equipment, that is, the plastic particles generated by the granulation equipment are directly introduced into the temporary storage tube 1 for temporary storage after preliminary dehydration, and the granulated plastic particles enter the temporary storage tube 1. A collecting mechanism 2 connected to the plurality of temporary storage tubes 1 is arranged in each granulation workshop 42, and the plastic particles in the plurality of temporary storage tubes 1 are conveyed to the collecting mechanism 2. A pneumatic conveying mechanism 9 is arranged between the granulation workshop 42 and the wire drawing workshop 43, and the pneumatic conveying mechanism 9 is used to convey the plastic particles to the granulation workshop 42. A plurality of granulation workshops 42 are connected to a wire drawing workshop 43, and the plastic particles produced in the granulation workshop 42 are transported to a plurality of wire drawing workshops 43 through a pneumatic conveying mechanism 9, so that the waste plastics can be transported over long distances with relatively high transport efficiency. At the same time, the plastic particles can be distributed during transport. A lifting mechanism 7 is provided between the pneumatic conveying mechanism 9 and the collecting mechanism 2, and the plastic particles in the collecting mechanism 2 are transported to the pneumatic conveying mechanism 9 through the lifting mechanism 7. A material distribution mechanism 32 is provided between the wire drawing workshop 43 and the pneumatic conveying mechanism 9, and the plastic particles in the pneumatic conveying mechanism 9 are transported to the wire drawing workshop 43 for re-melting and wire drawing through the material distribution mechanism 32. The pneumatic conveying mechanism 9 includes a conveying component 10 and a fan 24. One end of the conveying straight pipe 22 is connected to the high-pressure fan 24. The high-pressure fan 24 is connected to one end of the conveying component 10 through a flange, so that the high-pressure airflow flows in the conveying component 10. The conveying component 10 includes a conveying straight pipe 22 and a turning component 11. The turning component 11 is connected to the end of the conveying straight pipe 22. The conveying straight pipe 22 is rotatably connected to the turning component 11. A rotating component 25 is installed on the conveying straight pipe 22. The rotation of the conveying straight pipe 22 is achieved by the rotating component 25. When pneumatically conveying granular materials, the granular materials are relatively heavy and the granular materials are broken materials. The granular materials generally flow at the bottom of the conveying straight pipe 22. Long-term conveying will cause the granular materials to wear through the bottom of the conveying straight pipe 22. The conveying straight pipe is intact except for the bottom. The present application uses a rotating conveying straight pipe, so that the wear of the granular materials on the conveying straight pipe can be evenly distributed on the inner wall of the conveying straight pipe, thereby extending the service life of the conveying straight pipe. The turning assembly 11 includes a steering cylinder 12, a guide plate 13 and an air supply assembly 16. A through hole is opened on the circumferential outer wall of the steering cylinder 12. The circumferential outer wall of the steering cylinder 12 is fixed to the outer ring of the bearing by welding. One end of the conveying straight pipe 22 extends into the inner ring of the bearing and is welded and connected. In this way, the conveying straight pipe 22 is connected to the steering cylinder 12, and the granular material and airflow in the conveying straight pipe 22 enter the steering cylinder 12. The air supply assembly 16 and another conveying straight pipe 22 are respectively connected at both ends of the steering cylinder 12. The conveying straight pipe 22 is connected and connected to the end of the steering cylinder 12 through a sealed bearing. The air supply assembly 16 is an air pump. The air supply assembly 16 is connected and connected to the steering cylinder 12 through a pipeline. In this way, the high-pressure airflow of the air supply assembly 16 is directly passed into the steering cylinder 12, wherein the airflow passed into the steering cylinder 12 by the air supply assembly 16 is from the conveying straight pipe 2 at the other end of the steering cylinder 12. 2 outflow, so that the airflow of the air supply component 16 into the steering cylinder 12 is perpendicular to the airflow of the delivery straight pipe 22 input into the steering cylinder 12, so that the airflow input into the steering cylinder 12 by the delivery straight pipe 22 can be redirected, and the delivery straight pipe 22 is prevented from directly hitting the inner wall of the steering cylinder 12 when it is input into the steering cylinder 12, and at the same time, it is also prevented from being transported along the inner wall of the steering cylinder 12 by friction. A plurality of guide plates 13 distributed in a circular array are installed in the steering cylinder 12, and the guide plates 13 block the plastic particles transported by the delivery straight pipe 22. Each guide plate 13 is a spiral blade, and the guide plate 13 is rotatably connected to the inner wall of the steering cylinder 12. The guide plate 13 is blown by the air supply component 16 to rotate, and the plastic particles transported to the steering cylinder 12 by the delivery straight pipe 22 are gathered to the middle by the guide plate 13, so that the friction between the plastic particles and the inner wall of the steering cylinder 12 is reduced, and the service life of the steering cylinder 12 is extended.

[0031] A rotating ring 14 is installed on the inner wall of the steering cylinder 12 through a bearing. The rotating ring 14 rotates relative to the steering cylinder 12 through the bearing. A plurality of guide plates 13 are installed on the rotating ring 14 by welding, so that the plurality of guide plates 13 rotate with the rotating ring 14. The guide plate 13 is a spiral plate, and one end of the guide plate 13 located on the inner side is inclined in the opposite direction of the rotation of the guide plate 13, so that the guide plate 13 rotates counterclockwise under the action of the air supply component 16. When the guide plate 13 rotates, due to the inclined surface of the guide plate 13, the guide plate 13 gathers the plastic particles on the edge of the steering cylinder 12 to the middle when rotating, and then blows them away through the high-pressure airflow of the air supply component 16 and enters the next section of the conveying straight pipe 22, thereby realizing the steering of the plastic particles during pneumatic conveying.

[0032] The rotating ring 14 is slidably matched with the inner wall of the steering cylinder 12, and a bearing is installed on the outer wall of the rotating ring 14 by welding. The bearing on the rotating ring 14 is installed on the inner wall of the steering cylinder 12 and the outer wall of the bearing is in contact with the inner wall of the steering cylinder 12. The rotating ring 14 moves on the inner wall of the steering cylinder 12, and an adjusting component 15 is provided between the bearing and the inner wall of the steering cylinder 12. The position of the rotating ring 14 in the steering cylinder 12 is adjusted by the adjusting component 15; when pneumatic conveying is performed, the plastic particles directly impact the guide plate 13 and the friction of the plastic particles on the guide plate 13 causes damage to the guide plate 13, but the damage to the guide plate 13 is regional. The position of the guide plate 13 is adjusted by the adjusting component 15, so that the part of the guide plate 13 that is not impacted and worn is moved to a position opposite to the conveying straight pipe 22, thereby extending the service life.

[0033] A long strip-shaped adjusting groove 17 is opened on the outer wall of the upper and lower sides of the steering cylinder 12, and the adjusting groove 17 penetrates the outer wall of the steering cylinder 12. A rack 18 moving in the adjusting groove 17 is embedded in the adjusting groove 17. An adjusting motor is installed on the outer wall of the steering cylinder 12 by bolt fastening. An adjusting gear 19 meshing with the rack 18 is installed on the output shaft of the adjusting motor by welding. The adjusting motor drives the adjusting gear 19 to rotate, and the adjusting gear 19 drives the rack 18 to move in the adjusting groove 17. The inner side of the rack 18 is welded. The arc lining plate 20 is fixed on the inner wall of the steering cylinder 12, and a sliding groove 21 is opened for the arc lining plate 20 to be embedded. The arc lining plate 20 slides in the sliding groove 21, and the inner wall of the arc lining plate 20 is flush with the inner wall of the steering cylinder 12. The arc lining plate 20 is against the inner wall of the sliding groove 21. The arc lining plate 20 closes the adjustment groove 17. The outer ring of the bearing is fixed on the arc lining plate 20. The position of the rack 18 is adjusted by adjusting the motor to drive the adjusting gear 19. The movement of the rack 18 drives the movement of the guide plate 13, so that the position of the guide plate 13 is adjusted.

[0034] A plurality of rotating components 25 are arranged on each conveying straight pipe 22, and the rotating components 25 include rotating blades 26, a transmission rod 27 and a transmission component 28, wherein a plurality of rotating blades 26 distributed in a ring array are installed in each conveying straight pipe 22, and the rotating blades 26 are located in the middle of the conveying straight pipe 22, and the plastic particles are transported at the bottom of the conveying straight pipe 22, so that the rotating blades 26 will not affect the transportation of the plastic particles, and the plurality of rotating blades 26 are installed with the transmission rod 27 by welding, and the rotation of the rotating blades 26 drives the rotation of the transmission rod 27, and the transmission rod 27 passes through the conveying straight pipe 22 and the transmission rod 27 is connected to the conveying straight pipe 22 by a sealed bearing, and the transmission rod 27 extends out of the conveying straight pipe 22, and the transmission component 28 is installed at one end of the transmission rod 27 extending out of the conveying straight pipe 22; the transmission component 28 includes a mounting ring 29, a bevel gear ring 30 and The bevel gear 31 is provided with a mounting ring 29 on the conveying straight pipe 22, and the outer wall of the mounting ring 29 is installed on the outer wall of the granulation workshop 42 and the wire drawing workshop 43 through a bearing, and a bevel gear ring 30 is installed on the side of the mounting ring 29 by bolt fastening, and the bevel gear 31 is installed on the transmission rod 27 by welding, wherein the bevel gear 31 is meshed with the bevel gear ring 30, when airflow passes through the conveying straight pipe 22, the airflow drives the rotating blade 26 to rotate, so that the transmission rod 27 rotates, and the transmission rod 27 drives the bevel gear 31 to rotate, because the bevel gear 31 is meshed with the bevel gear ring 30, when the bevel gear 31 rotates, the bevel gear 31 rotates around the bevel gear ring 30, thereby driving the conveying straight pipe 22 to rotate, and when there is no airflow in the conveying straight pipe 22, the rotating blade 26 stops rotating, and the conveying straight pipe 22 stops rotating.

[0035] A plurality of spacers 23 distributed in a circular array are installed on the inner wall of the conveying straight pipe 22 by bolt fastening. When the conveying straight pipe 22 rotates, the spacers 23 rotate along with the conveying straight pipe 22, and the plastic particles are lifted upward along with the spacers 23. When the end of the spacers 23 away from the inner wall of the conveying straight pipe 22 tilts downward, the plastic particles break away from the spacers 23 and fall downward. In this way, the plastic particles are transported backward by the airflow. In this way, the spacers 23 can transport the plastic particles backward by lifting the material. Compared with the transportation of the plastic particles at the bottom of the conveying straight pipe 22, the pneumatic transportation by lifting the material is more efficient.

The particles directly enter the receiving box 40. When the valve 33 is opened, the conveying straight pipe 22 is connected, and the conveying straight pipe 23 and the receiving box 40 are blocked. In this way, the plastic particles are directly conveyed backwards. The bottom of the receiving box 40 is a conical bucket.
