Description

Technical Field

[0001] An intelligent control structure for sequential interval of underground transportation of domestic waste according to the present invention relates to a conveying structure for sequential interval of waste packages in an underground intelligent ecological recyclable system of domestic waste, belonging to the field of waste treatment. In particular, it relates to a conveying structure that separates waste packages through a separating rotor so that the waste packages are conveyed at intervals in a transmission pipeline. Background Art

[0002] The urban domestic waste collection and transportation system includes three parts: waste collection, transportation, and transfer. After waste is classified and collected through fixed-point trash bins, it is then centrally transported to a waste treatment station by waste transport vehicles at specific times. At present, due to the large population in Chinese cities, the daily generation and discharge of waste are huge, resulting in a serious load on the waste collection and transportation system. A huge amount of manpower, financial resources, and material resources are invested in waste treatment every year. The cost of waste collection and transportation is high. Moreover, during the collection and transportation process, waste collection vehicles lack awareness of cleaning management, and the collection and transportation process is dirty and messy. For the existing method of transporting waste through a pneumatic suction pipeline, its transportation suction force is limited and it is only suitable for short and medium-distance waste transportation. When it comes to medium and long-distance transportation, the operating cost and maintenance cost consumed are too high, and it is difficult to construct a large-scale integrated transportation pipeline.

[0003] An underground waste collection and transportation system designed by the applicant to solve the above problems includes structures such as a pumping station, a community waste delivery unit, a waste classification delivery box, a community waste transmission pipeline, a confluence unit, and a confluence pipeline. When the waste or waste packages put in multiple communities converge in the confluence pipeline of the confluence unit, they will stack and squeeze each other. When it comes to the transmission pipeline that needs to be narrowed after confluence, it is easy to cause pipeline blockage problems at its connecting and reducing parts, or the waste packages are closely adjacent to each other, greatly affecting the flowability of subsequent pipeline transportation. Summary of the Invention

[0004] In order to improve the above situation, an intelligent control structure for sequential interval of underground transportation of domestic waste according to the present invention provides a conveying structure that separates waste packages through a separating rotor so that the waste packages are conveyed at intervals in a transmission pipeline. This ensures the smoothness and transportation speed of transportation.

[0005] The intelligent control structure for sorting and spacing of underground domestic waste transportation of the present invention is realized as follows: The intelligent control structure for sorting and spacing of underground domestic waste transportation of the present invention is composed of a confluence pipeline, a separating rotor, through holes, branch pipes, a stepping motor, a transmission pipeline, bearings, flow-increasing propellers, flow-increasing holes, a retaining net, a limiting ring and a guiding column. One end of the confluence pipeline is open, and the other end is closed. A limiting ring is arranged inside the confluence pipeline. The side of the limiting ring facing the open end of the confluence pipeline is a slope. The separating rotor is rotatably placed inside the confluence pipeline and is located between the limiting ring and the other end of the confluence pipeline. The stepping motor is placed on the other end of the confluence pipeline. The motor shaft of the stepping motor extends into the confluence pipeline through the bearing. The stepping angle of the stepping motor is 60°. One end of the separating rotor is connected to the motor shaft of the stepping motor, and a guiding column is arranged at the other end of the separating rotor. The guiding column is a conical column. Three through holes are equally angled on the separating rotor, and three flow-increasing holes are equally angled on the separating rotor. Flow-increasing propellers are arranged inside the flow-increasing holes, and a retaining net is arranged at the entrance of the flow-increasing holes. The through holes and the flow-increasing holes are spaced apart. Two branch pipes are connected to and communicate with the other end of the confluence pipeline. The other ends of the branch pipes first extend horizontally and then approach each other. The inner diameter of the branch pipes is the same as the aperture of the through holes. The transmission pipeline is connected to and communicates with the other ends of the two branch pipes.

[0006] Beneficial effects.

[0007] First, it can evenly divert and transport a large number of garbage and garbage packages in the confluence pipeline, avoiding blockage at the reduced-diameter part.

[0008] Second, it can make the garbage packages be transported at intervals in the transmission pipeline, ensuring the spacing between adjacent ones, so as to ensure the smoothness and transportation speed of the transportation.

[0009] Third, it can form an auxiliary speed increase for the transportation of garbage packages while sorting and sequencing, improving the transportation efficiency at the reduced-diameter position. Description of the drawings

[0013] Among them are: confluence pipeline (1), separating rotor (2), through hole (3), branch pipe (4), stepping motor (5), transmission pipeline (6), bearing (7), flow-increasing propeller (8), flow-increasing hole (9), retaining net (10), limiting ring (11), guiding column (12). Detailed implementation mode

[0014] The intelligent control structure for sequential interval of underground transportation of domestic waste in the present invention is realized as follows: The intelligent control structure for sequential interval of underground transportation of domestic waste in the present invention is composed of a confluence pipeline (1), a partition rotor (2), through holes (3), branch pipes (4), a stepping motor (5), a transmission pipeline (6), bearings (7), flow increasing propellers (8), flow increasing holes (9), a retaining net (10), a limiting ring (11) and a guide column (12). One end of the confluence pipeline (1) is open, and the other end of the confluence pipeline (1) is closed. A limiting ring (11) is arranged inside the confluence pipeline (1). The side of the limiting ring (11) facing the open end of the confluence pipeline (1) is a slope. The partition rotor (2) is rotatably placed inside the confluence pipeline (1) and is located between the limiting ring (11) and the other end of the confluence pipeline (1). The stepping motor (5) is placed on the other end of the confluence pipeline (1). The motor shaft of the stepping motor (5) extends into the confluence pipeline (1) through the bearing (7). The stepping angle of the stepping motor (5) is 60°. One end of the partition rotor (2) is connected to the motor shaft of the stepping motor (5). A guide column (12) is arranged at the other end of the partition rotor (2). The guide column (12) is a conical column. Three through holes (3) are equally angled on the partition rotor (2). Three flow increasing holes (9) are equally angled on the partition rotor (2). Flow increasing propellers (8) are arranged inside the flow increasing holes (9). A retaining net (10) is arranged at the entrance of the flow increasing holes (9). The through holes (3) and the flow increasing holes (9) are spaced apart. Two branch pipes (4) are connected to and communicate with the other end of the confluence pipeline (1). The other ends of the branch pipes (4) first extend horizontally and then approach each other. The inner diameter of the branch pipes (4) is the same as the aperture of the through holes (3). The transmission pipeline (6) is connected to and communicates with the other ends of the two branch pipes (4);

[0015] In an underground intelligent ecological recyclable system for domestic waste applied by the applicant, when the garbage or garbage packages put in multiple communities converge in the confluence pipeline (1) of the confluence unit, they will stack and squeeze each other. When it is necessary to enter the transmission pipeline (6) with a smaller diameter after the confluence is completed, it is easy to cause pipeline blockage at the connection and variable diameter part, or the garbage packages are closely adjacent to each other, greatly affecting the flowability of the subsequent pipeline transportation. Therefore, the applicant proposes an intelligent control structure for sequential interval of underground transportation of domestic waste to solve the problem;

[0016] During use, one end of the confluence pipe (1) is connected and communicated with an existing underground garbage transportation pipe, and the transmission pipe (6) is connected and communicated with the existing underground garbage transportation pipe. The garbage is stored in garbage packages and is sequentially transported through the confluence pipe (1), the through hole (3), the branch pipe (4), and the transmission pipe (6). The stepping motor (5) controls the partition rotor (2) to rotate at an interval of 60 degrees. Each time it rotates, there will be a through hole (3) on the partition rotor (2) aligned with one of the branch pipes (4), while the other branch pipe (4) is blocked by the retaining net (10) in the flow increasing hole (9) to prevent the garbage package from passing through. In this way, the garbage in the corresponding through hole (3) can pass through the partition rotor (2) and reach the transmission pipe (6) through the branch pipe (4), and the remaining group of branch pipes (4) will be aligned with the flow increasing hole (9). The increasing force spiral inside it will push the water flow to increase the speed, and the garbage package that enters the auxiliary branch pipe (4) during the rotation of the upper group will be pushed to increase the speed. In this way, the two branch pipes (4) alternately and orderly transport the garbage at the river pipeline at regular intervals and times, avoiding blockage at the reduced diameter part;

[0017] The side of the limit ring (11) facing the open end of the confluence pipe (1) is designed as a slope, which is convenient for the propulsion and installation of the partition rotor (2), and forms a constricted structure in cooperation with the guide column (12) to increase the speed of the water flow in the confluence pipe (1);

[0018] The guide column (12) is designed as a conical column to reduce the resistance to the water body and avoid impact damage;

[0019] The design of disposing a retaining net (10) at the entrance of the flow increasing hole (9) can block the branch pipe (4) that does not need to be transported, realize the intermittent transportation of the garbage package in the transmission pipe (6), ensure the distance between adjacent ones, thereby ensuring the smoothness and transportation speed of transportation, and can filter the water body;

[0020] The other end of the branch pipe (4) first extends horizontally and then approaches each other, so as to concentrate the separated garbage packages into one pipe for transportation again, avoiding the increase in the number of pipelines affecting normal transportation use;

[0021] The design that the inner diameter of the branch pipe (4) is the same as the aperture of the through hole (3) can avoid the generation of bumps and damages to the garbage package due to sharp corners;

[0022] The design of spacing the through hole (3) and the flow increasing hole (9) apart enables the two branch pipes (4) to alternately transport the garbage package, perform intermittent transportation, ensure the distance between adjacent ones, thereby ensuring the smoothness and transportation speed of transportation;

[0023] The purpose of separating the garbage package by the partition rotor (2) and enabling the garbage package to be intermittently transported in the transmission pipe (6) is achieved.
