Description

Technical Field

[0001] The utility model relates to a particle conveying pipeline. Background Art

[0002] After granulation, plastic pellets are quite hot. During the process of being transported through the pipeline by the negative pressure fan, plastic pellets may adhere to the pipeline. Long-term accumulation can easily cause pipeline blockage, requiring regular pipeline cleaning. However, pipelines are generally long, and disassembly for cleaning requires downtime, and the disassembly and assembly process is cumbersome, which may cause sealing problems after reassembly. Utility Model Content

[0003] In order to overcome the above-mentioned deficiencies, the present invention provides a particle conveying pipeline, which facilitates regular cleaning of the pipeline.

[0004] To achieve this purpose, the structure adopted by the utility model is: a particle conveying pipeline, including an upper tube body and a lower tube body, the upper tube body and the lower tube body are connected by a flange, a connecting block is provided on the inner wall of the upper tube body near the flange, a first air blowing pipe is inserted into the connecting block, the first air blowing pipe is connected to the second air blowing pipe through a flexible pipe, and the second air blowing pipe is connected to the tube wall of the upper tube body by a connecting rod and a connecting rod group.

[0005] The air outlet end of the second air blowing pipe is provided with a tapered nozzle.

[0006] The flexible pipe is a metal hose.

[0007] The beneficial effect is that the structural design of the utility model is reasonable and ingenious. When cleaning the pipeline, the nozzle of the air gun is pointed at the air inlet of the first air blowing pipe to spray air. By pushing and pulling the first air blowing pipe, the angle of the second air blowing pipe in the pipe body can be adjusted to achieve cleaning of the inner wall of the pipe body. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The present invention will be described by way of examples with reference to the accompanying drawings, in which:

[0009] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0010] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0011] In the description of the utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," "the other end," and the like, indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of the utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0012] In the description of the utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc., should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components; a fixed connection can be welding or gluing. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0013] like Figure 1 The particle conveying pipeline shown includes an upper tube body 1 and a lower tube body 2, which are connected by a flange 3. A connecting block 4 is provided on the inner wall of the upper tube body 1 near the flange 3. A through hole is provided on the connecting block 4 and the upper tube body 1. A first air blowing pipe 5 is provided in the through hole. The first air blowing pipe 5 is a metal tube body. A sealing ring is provided between the first air blowing pipe 5 and the connecting block 4. The first air blowing pipe 5 can move back and forth in the through hole. One end of the first air blowing pipe 5 is outside the upper tube body 1. On the other side, the other end is on the inner side of the upper tube body 1, and the second air blowing pipe 6 is connected to the first air blowing pipe 5 at the pipe mouth at one end on the inner side. The second air blowing pipe 6 is connected to the first air blowing pipe 5 through a flexible pipe. When the end of the first air blowing pipe 5 located on the outer side of the upper tube body 1 is connected to the blow nozzle of the air gun, high-pressure gas is blown into the upper tube body 1 from the second air blowing pipe 6, and the particles attached to the inner wall of the upper tube body 1 are blown away, thereby cleaning the pipeline without disassembling the pipeline. At the same time, the air blowing pipe and its mounting structure can be easily inspected and repaired near the flange 3.

[0014] The first air blowing pipe 5 can be connected to multiple second air blowing pipes 6 at the same time. One end of the second air blowing pipe 6 is connected to the inner wall of the upper tube body 1 through a connecting rod 7. The connecting rod 7 and the second air blowing pipe 6 are connected by a pin. The other end is connected to the inner wall of the upper tube body 1 through a connecting rod group 8. The connecting rod group 8 includes multiple connecting rods connected to each other by pins. When the first air blowing pipe 5 is pushed or pulled, the second air blowing pipe 6 can rotate around the point where it is connected to the connecting rod 7 under the action of the connecting rod group 8.

[0015] One end of the second air blowing pipe 6 is connected to the first air blowing pipe 5, and the other end is an air outlet. A nozzle is provided at the air outlet. The nozzle is a conical nozzle, and the air flow diverges and sprays in a conical shape.

[0016] The flexible pipe adopts a metal hose structure, which not only ensures the connection but also extends the service life of the overall structure.

[0017] The above description is based on the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the content of the specification. Its technical scope must be determined according to the scope of the claims.
