[0032] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0033] like Figure 1 and Figure 2As shown, an embodiment of the utility model provides a conveying pipeline, including: a pipeline body 1, a ceramic lining 2 and a reinforcement layer 3. A plurality of ceramic liners 2 are inlaid on the inner wall of the pipeline body 1, and the plurality of ceramic liners 2 are arranged in sequence along the axial direction of the pipeline body 1, and there is a certain gap between two adjacent ceramic liners 2. The reinforcement layer 3 is arranged inside the tank body and is located on the side away from the ceramic lining 2. When installing the conveying pipeline, the inlet end and the outlet end of the conveying pipeline can be installed concentrically according to actual needs. Or the inlet and outlet of the conveying pipeline can be eccentric after installation.
[0034] Since the pipe body 1 has a certain flexibility, the pipe body 1 can be bent along its axis during installation. In order to prevent the ceramic lining 2 embedded in the pipe body 1 from affecting its bending, there is a certain gap between two adjacent ceramic liners 2 distributed along its axis. In order to improve the pressure bearing capacity of the pipe body 1, a reinforcement layer 3 is arranged in the pipe body 1.
[0035] In one of the embodiments, the pipe body 1 is made of rubber. When the pipe body 1 is vulcanized, the ceramic lining 2 is embedded in the inner wall of the pipe body 1 , and the reinforcement layer 3 is wrapped by the outer wall of the pipe body 1 .
[0036] Since the pipe body 1 is made of rubber, the ceramic lining 2 is first fixed on the inner wall of the pipe body 1, and then the reinforcement layer 3 is sleeved on the outside of the pipe body 1. Finally, it is vulcanized, and during the vulcanization process, the ceramic lining 2 is embedded on the inner wall of the pipe body 1. The reinforcement layer 3 is embedded in the pipe body 1, so that the pipe body 1 completely wraps the reinforcement layer 3.
[0037] The ceramic lining 2 and the reinforcement layer 3 are fixed during the vulcanization process, so that the structure of the conveying pipeline is simpler.
[0038] In one embodiment, if Figure 2 As shown, the ceramic lining 2 is arranged in a ring shape, and the pipe body 1 is provided with a plurality of the ceramic liners 2 at equal intervals along the axial direction thereof.
[0039] In order to facilitate the laying of ceramic lining 2, such as Figure 1 and Figure 2 As shown, the ceramic liner 2 is arranged as an annular structure and is installed equidistantly in the pipe body 1. During the vulcanization process, the rubber on the pipe body 1 fixes the ceramic liner 2 on the inner wall of the pipe body 1.
[0040] The ceramic lining 2 with an annular structure also has the advantage of being easy to install, and only the distance along the axial direction of the pipeline body 1 needs to be controlled.
[0041] In one embodiment, the reinforcing layer 3 is a mesh structure formed by weaving cords into an annular shape. After being sleeved on the pipe body 1, the mesh holes of the mesh structure are in a diamond shape.
[0042] The reinforcing layer 3 is woven from cords because the cords have the advantages of high strength and initial modulus, good heat resistance, good fatigue resistance and impact load resistance, good dimensional stability and the ability to bond with rubber.
[0043] After the vulcanization treatment, the reinforcement layer 3 is located inside the pipeline body 1 , thereby improving the pressure bearing capacity of the pipeline body 1 .
[0044] In one embodiment, if Figure 3 As shown, the ceramic lining 2 is of a polygonal structure and is arranged in rows and at equal intervals along the axial direction of the pipe body 1 . The ceramic linings 2 arranged in rows and at equal intervals are evenly distributed along the circumference of the pipe body 1 .
[0045] When the ceramic lining 2 is a polygonal structure, the ceramic lining 2 along the axis of the pipe body 1 needs to be aligned during installation, and the ceramic lining 2 is in the same straight line after installation. The ceramic lining 2 covers the inner wall of the pipe body 1 according to the previous distribution method.
[0046] In order to further demonstrate the conveying effect of the utility model, a detailed description is given using silicon particles as the conveying medium. The inlet end of the pipeline body 1 is connected to the discharge port of the silicon particles through a flange. After the silicon particles enter the pipeline body 1, they come into contact with the ceramic lining 2 disposed in the pipeline body 1. During the contact process, the wear resistance of the pipeline body 1 is improved due to the high hardness of the ceramic lining 2, thereby indirectly increasing the service life of the pipeline body 1. During the transportation of silicon particles, some silicon particles may impact the pipeline body 1. After the impact force acts on the ceramic lining 2, it is instantly absorbed by the pipeline body 1, so it has a certain vibration absorption effect.
[0047] The above-mentioned placement and arrangement of the ceramic lining 2 can also realize non-concentric installation of the inlet and outlet of the conveying pipeline, so that the conveying pipeline has better flexibility during installation.
[0048] In order to increase the service life of the delivery pipeline, a reinforcement layer 3 is provided in the pipeline body 1, so that the delivery pipeline has a certain pressure bearing capacity.
[0049] When the conventional conveying pipeline is used to convey silicon particles, the pipeline will be worn and leaked when conveying 600-700 tons of silicon particles. However, after actual use, it is known that the technical solution described in this application does not cause the pipeline to be worn and leaked after conveying 6000-7000 tons of silicon particles. Therefore, the conveying pipeline described in this application has the advantage of a longer service life compared with the conveying pipeline described in the prior art.
[0050] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
