Description

TECHNICAL FIELD

[0001] The application relates to the technical field of plastic recycling, in particular to a pipeline conveying device. BACKGROUND

[0002] In today's society, the widespread use of plastic products has led to an increasing amount of plastic waste, and the importance of the plastic recycling industry has become increasingly prominent. However, in the actual plastic recycling process, there are many difficult problems to be solved. In the plastic recycling process, the sources of waste plastic products are extremely extensive and complex, including various plastic packaging in daily life, waste plastic parts in industrial production, and post-consumer plastic garbage, etc. These plastic waste often contains a large amount of sundries without strict classification and screening in the collection stage. These sundries are of various types, including but not limited to various metal fragments, glass slag, paper, fabric fibers, sand, wood chips and other organic and inorganic impurities, etc. When these plastics mixed with a large amount of sundries enter the recycling process, if not effectively separated, it will have a serious negative impact on the subsequent storage, processing and recycling links. CONTENT OF THE UTILITY MODEL

[0003] The purpose of the application is to provide a pipeline conveying device for separating sundries from plastics.

[0004] The pipeline conveying device provided by the application adopts the following technical scheme: a feeding pipe, an inclined pipe, a plurality of elbow pipes, a plurality of conveying pipes, and a fan connected to the feeding pipe, the feeding pipe is connected to the inclined pipe through the elbow pipe, the inclined pipe is connected to the conveying pipe through the elbow pipe, the feeding pipe is provided with a material receiving port, and the inclined pipe is provided with a material outlet.

[0005] By adopting the above scheme, the fan is connected to the feeding pipe, which can provide power for the material conveying in the entire pipeline. By generating airflow, the material is pushed to move along the pipeline from the material receiving port to the material outlet, ensuring that the material can be continuously and stably transmitted in the pipeline; the feeding pipe receives the material first, then the material is transferred to the inclined pipe through the elbow pipe, and then the material is connected to the conveying pipe through the elbow pipe until the material outlet, the multi-section design can play a certain buffering and regulating role in the conveying process of the material.

[0006] Preferably, the material receiving port is fixedly connected with a plurality of material receiving plates, and the plurality of material receiving plates surround the material receiving port.

[0007] By adopting the above scheme, the several material receiving plates are arranged around the material receiving opening, which can expand the effective range of material receiving in the horizontal direction. When the external material supply device delivers material to the material receiving opening, even if the falling point of the material has a certain deviation, the material receiving plate can play a role of interception and guidance; the material receiving plates around the material receiving opening form a physical barrier, which can effectively prevent the material from splashing out in all directions at the moment of entering the material receiving opening.

[0008] Preferably, the material receiving opening is fixedly connected with an inclined plate, the highest point of the inclined plate is close to the fan, the height of the inclined plate extending into the feeding pipe is a, the diameter of the feeding pipe is b, and a:b is 1:(1.5-2).

[0009] By adopting the above scheme, the reasonable height of the inclined plate (a:b maintains the proportional relationship of 1:(1.5-2) with the diameter b of the feeding pipe) can avoid excessive obstruction or disturbance of the airflow generated by the inclined plate to the fan. If the inclined plate extends too high, it may block most of the airflow, so that the airflow cannot be uniformly distributed in the feeding pipe, affecting the overall conveying of the material; and if the inclined plate extends too low, it cannot fully play its role of guiding the material and cooperating with the airflow; the highest point of the inclined plate is close to the fan, which is beneficial to fully utilize the airflow generated by the fan. When the airflow blown by the fan meets the inclined plate, it will flow along the surface of the inclined plate and better interact with the sliding material. The airflow can wrap the material more efficiently along the inclined plate and push it to move forward, enhancing the initial power obtained by the material in the feeding pipe, so that the material can start the conveying journey in the pipe at a faster speed and in a more stable state, improving the starting efficiency of the material conveying.

[0010] Preferably, the discharge opening is provided with a slope on one side, the slope faces the conveying airflow, the minimum distance between the slope and the other side of the inclined pipe is c, the diameter of the inclined pipe is d, and c:d is less than or equal to 0.76 and greater than or equal to 0.8.

[0011] By adopting the above scheme, the slope is arranged on one side of the discharge port and faces the conveying airflow, so that the material can be guided to flow out of the discharge port more smoothly along the slope direction by the power of the airflow. When the material is pushed by the airflow to the vicinity of the discharge port in the pipeline conveying device, the airflow impacting on the slope will change the flow direction and simultaneously push the material to slide out along the slope. The ratio of the minimum distance c between the slope and the other side of the inclined pipe to the diameter d of the inclined pipe is within a certain range (less than or equal to 0.76 and greater than or equal to 0.8), which ensures that the slope neither occupies too much space in the inclined pipe to cause the effective cross-sectional area of the material passing through to be too small, affecting the normal conveying speed and flow of the material, nor can the function of guiding the material out be fully played. The slope and the conveying airflow can achieve good adaptation effect within the ratio range. If the ratio of c:d is too large, the slope is too far from the other side, which may cause the airflow to be excessively dispersed before reaching the slope, so that the airflow cannot effectively act on the slope to push the material out; if the ratio is too small, the slope is too close to the other side, which may form a large obstacle to the normal flow of the airflow, causing the airflow to be turbulent, which is also not conducive to the material out. Within the suitable ratio range, the airflow can smoothly impact the slope and guide the material out, maintaining the stable and effective effect of the airflow in the discharging link.

[0012] Preferably, the angle e formed by the inclined pipe and the feeding pipe is greater than or equal to 135° and less than or equal to 150°.

[0013] By adopting the above scheme, within this angle range, the material can smoothly slide down when it is transferred from the feeding pipe to the inclined pipe. When the fan pushes the material to move along the feeding pipe and reaches the connection with the inclined pipe, the suitable angle enables the material to naturally slide down along the inclined direction of the inclined pipe, avoiding the collision impact and breakage that may occur due to the sharp falling of the material caused by an excessively steep angle, and preventing the material from being accumulated and jammed at the connection, which cannot smoothly enter the inclined pipe for continuous conveying, thereby ensuring the continuity and smoothness of the material conveying process; the connection part of the inclined pipe and the feeding pipe bears the pressure of the material and the airflow, and when the angle e is within the range of greater than or equal to 135° and less than or equal to 150°, the force can be reasonably dispersed at the connection.

[0014] Preferably, the angle f formed by the inclined plate and one side of the feeding pipe is greater than or equal to 145° and less than or equal to 155°.

[0015] By adopting the above scheme, the inclined plate can more accurately and efficiently guide the flow direction of the material in the feeding pipe. When the material falls on the inclined plate after entering the receiving port, due to the reasonable setting of the angle f, the material will slide down along the inclined plate in a relatively ideal direction, avoiding the situation that the material flows in the wrong direction or is not evenly distributed, so that the material can be orderly and evenly distributed on the cross section of the feeding pipe, laying a good foundation for stable conveying in the subsequent pipeline conveying device, ensuring that the material can fully utilize the space of the feeding pipe and smoothly enter the subsequent pipeline part; when the angle f is in the interval of greater than or equal to 145° and less than or equal to 155°, this layout of the inclined plate and the feeding pipe is more conducive to the cooperative work of the fan airflow. When the airflow blown by the fan flows near the inclined plate, it can flow more smoothly along the surface of the inclined plate, and can better adhere to the inclined plate to move the material. This angle makes the interaction between the airflow and the inclined plate and the material more reasonable and efficient, neither causing the airflow to be unable to fully utilize the inclined plate to push the material due to an inappropriate angle, nor causing the airflow to be too hindered and disordered, thereby ensuring that the material obtains sufficient and stable initial conveying power in the feeding pipe and improving the efficiency of the material conveying starting stage.

[0016] Preferably, the conveying pipeline at the end is communicated with a three-way pipeline, and a baffle is rotatably connected in the three-way pipeline. The baffle enables the three-way pipeline to switch between different outlets.

[0017] By adopting the above scheme, the baffle changes its position in the three-way pipeline by rotating, thereby realizing the opening and closing control of different outlets. When the baffle is rotated to a certain position, one outlet of the three-way pipeline is blocked, so that the material can only flow to one of the other two outlets or simultaneously flow to two outlets. During the material conveying process, the material flows in the conveying pipeline under the action of the fan or other power source. When reaching the three-way pipeline, due to the blocking and guiding action of the baffle, the material changes the flow direction according to the position of the baffle, thereby entering the specified outlet pipeline for continuous conveying.

[0018] Preferably, the conveying pipe at the end is provided with a reversing pipeline, and the reversing pipeline can rotate in the pipeline conveying device.

[0019] By adopting the above scheme, the reversing pipeline changes the orientation of its port by itself, thereby changing the conveying direction of the material. When it is rotated to different angles, the material originally running along the conveying pipe will continue to flow along the new outlet direction of the reversing pipeline, so as to achieve flexible adjustment of the material flow direction at the end of the pipeline conveying device system.

[0020] In summary, the present application has at least one of the following beneficial technical effects:

[0021] 1. The fan connected to the feed pipe provides stable power for material conveying throughout the pipeline, ensuring that the material can move continuously and stably from the receiving port to the discharge port, effectively improving conveying efficiency. It is especially suitable for large-scale material transportation scenarios, reducing the stagnation time of materials in the pipeline and ensuring the continuity of the production process. The reasonable structural design of the inclined plate and the feed pipe (height ratio and angle setting) makes full use of the airflow of the fan, so that the material can obtain sufficient and stable initial power in the feed pipe, enabling it to start the conveying journey at a faster speed and in a stable state, avoiding the accumulation of materials and slow start-up in the initial stage, and further improving the overall conveying efficiency.

[0022] 2. The angle between the inclined tube and the feed tube is set within a suitable range to reasonably distribute the force at the connection, reduce the impact of material and airflow on the connection, reduce the risk of damage or deformation of the connection structure, extend the service life of the pipe connection, reduce the frequency of pipe repair and replacement, and lower maintenance costs.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail.

[0031] The embodiment of the present application discloses a pipeline conveying device.

[0032] Embodiment 1, refer to Figure 1 、 Figure 2 and Figure 3 A pipeline conveying device comprises a feeding pipe 1, an inclined pipe 3, a plurality of elbow pipes 2, a plurality of conveying pipes 4, and a fan 6 connected with the feeding pipe 1, the feeding pipe 1 is connected with the inclined pipe 3 through the elbow pipes 2, the inclined pipe 3 is connected with the conveying pipes 4 through the elbow pipes 2, the feeding pipe 1 is provided with a material receiving port 11, and the inclined pipe 3 is provided with a material outlet 32; in the embodiment 1, the feeding pipe 1 is made of a stainless steel pipe with a diameter of 300 mm, the material receiving port 11 is arranged at one end of the feeding pipe 1, and four material receiving plates 12 are fixedly connected at the material receiving port 11, each of the material receiving plates 12 is a stainless steel sheet with a length of 400 mm and a width of 200 mm, is uniformly distributed at 90° around the material receiving port 11, and effectively expands the material receiving range. Meanwhile, an inclined plate 18 is welded in the material receiving port 11, the height a of the inclined plate 18 extending into the feeding pipe 1 is 150 mm, the angle f formed by the inclined plate 18 and one side of the feeding pipe 1 is 150°, the inclined plate 18 is made of a stainless steel plate with a thickness of 5 mm, the highest point of the inclined plate 18 is close to the connected fan 6, and the fan 6 is a centrifugal fan 6 with a power of 5 kW, which can generate sufficient airflow to push the material to be conveyed in the pipeline.

[0033] Reference Figure 2 and Figure 4 The feeding pipe 1 is connected with the inclined pipe 3 through the elbow pipes 2, the bending angle of the elbow pipes 2 is 120°, so that the pipeline can bypass some obstacles and realize smooth transition. The angle e formed by the inclined pipe 3 and the feeding pipe 1 is 140°, the diameter of the inclined pipe 3 is the same as that of the feeding pipe 1, that is, 300 mm, and the length of the inclined pipe 3 is 2 m, the material outlet 32 is arranged at one end of the inclined pipe 3, the inclined slope 31 is welded on one side of the material outlet 32, the inclined slope 31 faces the transportation airflow, the minimum distance c from the other side of the inclined slope 31 to the inclined pipe 3 is 240 mm, the inclined slope 31 is made of a stainless steel plate with the same material as the inclined pipe 3, and the inclination angle is 30°, so that the material can smoothly slide out.

[0034] Reference Figure 2For example, in the left and right directions of the figure, the right side of the inclined plate 18 is the high-pressure area 13, and the left side is the adsorption area 15. The transport area 14 is located below the adsorption area 15 and is in a scattered form. The plastic enters the adsorption area 15 under the guidance of the inclined plate 18, and the adsorption area 15 adsorbs the plastic obliquely downward into the transport area 14, which is close to the bottom wall of the feed pipe 1. The plastic is transported along the bottom wall of the pipeline. After the airflow in the transport area 14 is lifted by the inclined pipe 3 and the slope 31, it is close to the top wall. On the one hand, this allows the plastic to obtain a jumping area 17, in which the heavier impurities jump to a lower height. As the airflow decreases near the through slot, the heavier impurities will fall into the discharge port 32. On the other hand, the transport area 14 is better transitioned to the advection area 16, and the lifted airflow is more evenly distributed in the channel. Such a design optimizes the transportation process, and through the synergistic effect of the inclined plate 18 and the slope 31, the material can be better separated and transported during transportation, improving the transportation efficiency and quality. At the same time, the formation of the advection area 16 helps to stabilize the airflow, further improving the stability and reliability of the transportation.

The output shaft of the motor is fixedly connected with the baffle 51. The rotation of the baffle 51 in the pipe conveying device is realized by the motor, which can flexibly change the conveying direction of the material. The rotation angle range is 0°-80°, so that the material can be transported to different places.

[0036] In example 2, reference is made to Figure 6 The difference between this embodiment and example 1 is that it further includes a support 7 for installing the overall pipe, the support 7 is fixedly connected with a mounting frame 53, the last end conveying pipe 4 is rotatably connected with a reversing pipe 52, the reversing pipe 52 is provided with an annular gear 54 outside, the mounting frame 53 is fixedly connected with a motor, the output end of the motor is connected with the annular gear 54 through a gear, the reversing pipe 52 is fixedly connected with a circular ring 55, and the mounting frame 53 is provided with a plurality of guide wheels 56, which are located on both sides of the circular ring 55 and abut against the circular ring 55.
