Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tire manufacturing, in particular to a pipeline anti-scouring device and a pipeline discharge system. Background Art
[0002] In the existing tire manufacturing process, a large amount of steam is required. Among them, as shown in the existing pipeline discharge system Figure 1 composed of an air outlet branch pipe 100, a cut-off valve 200, and a discharge main pipe 300. The steam of each medium is discharged into the discharge main pipe 300 through the air outlet branch pipe 100. However, since the air outlet branch pipe 100 is vertically installed with the discharge main pipe 300, the medium steam directly scours the inner wall of the discharge main pipe 300. Due to the relatively high discharge pressure of the medium steam, in the long run, the side wall (at point A) of the main pipe 300 will become thinner until it is damaged and leaks, thus affecting production. Summary of the Invention
[0003] In order to solve the above problems, the first object of the utility model is to provide a pipeline anti-scouring device, which is connected to the end of the air outlet branch pipe and extends into the discharge main pipe, and can change the discharge direction of the medium steam, avoid pipeline breakage and leakage caused by long-term scouring, and thus extend the service life of the pipeline; the second object of the utility model is to provide a pipeline discharge system with the above pipeline anti-scouring device.
[0004] In order to achieve the above objects, the utility model adopts the following technical solutions:
[0005] A pipeline anti-scouring device, characterized in that: it includes a pipe body penetrating through the discharge main pipe, the upper end of the pipe body extends out of the discharge main pipe and forms an air inlet, and the air inlet is fixedly communicated with the end of the air outlet branch pipe; an exhaust passage communicating with the air inlet is constructed inside the pipe body; the lower end of the pipe body is closed, and at least one air outlet hole communicating with the exhaust passage is opened on the lower side wall of the pipe body inside the discharge main pipe, and the air outlet holes are horizontally arranged along the extending direction of the discharge main pipe.
[0006] In the above technical solution, a pipeline anti-scouring device is fixedly connected to the end of the air outlet branch pipe. This device is in the shape of a short tube, and a part of the pipe body extends out of the discharge main pipe, which is convenient for installation with the air outlet branch pipe and subsequent maintenance of the connection; another part of the pipe body extends into the discharge main pipe and the bottom of this part is closed, and air outlet holes are provided on the side wall of this part. Therefore, the medium steam in the air outlet branch pipe comes out from the air outlet holes and is horizontally discharged after passing through the exhaust passage in the pipe body, and the discharge direction is along the extending direction of the discharge main pipe. Furthermore, the discharge direction of the medium steam is changed, and no scouring at any angle will be caused to the discharge main pipe, thus greatly extending the service life of the pipeline, reducing the maintenance cost, and being particularly suitable for discharge pipelines with relatively high pressure.
[0007] It should be noted here that the specific dimensions of the pipeline erosion prevention device (pipe body) inserted through the discharge main pipe can be determined according to the size of the discharge main pipe.
[0008] Preferably, there are two air outlet holes which are symmetrically arranged on the lower side wall of the pipe body. In this technical solution, the setting of the two air outlet holes can increase the discharge amount of the medium steam and prevent the internal pressure of the pipe body from being too high, which affects the assembly stability of the pipe body.
[0009] Preferably, the bottom of the exhaust passage is constructed into a downwardly concave arc shape. In this technical solution, the arc-shaped bottom of the exhaust passage plays a buffering role for the medium steam and guides the medium steam to the two air outlet holes to be discharged into the discharge main pipe, reducing the erosion of the medium steam on the pipe body to a certain extent and improving the assembly stability of the pipe body.
[0010] Preferably, a step is formed circumferentially on the upper part of the exhaust passage, and an assembly space is formed between the step and the air inlet. The air outlet branch pipe extends into the assembly space and is fixedly welded to the pipe body. In this technical solution, the setting of the step forms an assembly space between the step and the air inlet, and the air outlet branch pipe extends into the assembly space and is fixedly welded to the pipe body, which can increase the welding area between the air outlet branch pipe and the pipe body and improve the connection strength between the air outlet branch pipe and the pipe body. In addition, the end of the air outlet branch pipe can also be fixedly welded to the edge of the end of the air inlet of the pipe body, but the welding area is small and the connection strength will decrease; its connection structure can also be that the end of the air outlet branch pipe is sleeved outside the pipe body, but it will erode the entire pipe body and affect the assembly stability; in addition to the above methods, the connection structure can also use other effective fixed connection structural methods.
[0011] Preferably, the side wall of the pipe body is fixedly welded to the discharge main pipe. In this technical solution, the side wall of the pipe body is fixedly welded to the discharge main pipe, which can improve the connection strength between the discharge main pipe and the pipe body and prevent the pipe body from shaking during the discharge process.

Embodiment 1:
[0022] As Figures 2-3 shown, a pipeline anti-erosion device includes a pipe body 1 penetrated through a discharge main pipe 300. The upper end of the pipe body 1 extends out of the discharge main pipe 300 and forms an air inlet 2, and the air inlet 2 is fixedly communicated with the end of an air outlet branch pipe 100; an exhaust passage 3 communicated with the air inlet 2 is constructed inside the pipe body 1; the lower end of the pipe body 1 is closed, and at least one air outlet hole 4 communicated with the exhaust passage 3 is opened in the lower side wall of the pipe body 1 inside the discharge main pipe 300, and the air outlet holes 4 are horizontally arranged along the extending direction of the discharge main pipe 300.
[0023] In the above technical solution, the end of the air outlet branch pipe is fixedly connected with a pipeline anti-erosion device. The device is in the shape of a short tube, and a part of the pipe body extends out of the discharge main pipe, which is convenient for installing with the air outlet branch pipe and for maintaining the subsequent connection part; another part of the pipe body extends into the discharge main pipe and the bottom of this part is closed, and air outlet holes are arranged on the side wall of this part. Therefore, the medium steam in the air outlet branch pipe comes out from the air outlet holes after passing through the exhaust passage in the pipe body and is horizontally discharged, and the discharge direction is along the extending direction of the discharge main pipe, thereby changing the discharge direction of the medium steam and not causing any angular erosion to the discharge main pipe, thus greatly prolonging the service life of the pipeline and reducing the maintenance cost, and is particularly suitable for discharge pipelines with higher pressure.
[0024] It should be noted here that the specific dimensions of the pipeline anti-erosion device (pipe body) penetrated through the discharge main pipe can be determined according to the size of the discharge main pipe.
[0025] Furthermore, two air outlet holes 4 are provided and symmetrically arranged on the lower side wall of the pipe body 1. In this technical solution, the setting of the two air outlet holes can increase the discharge amount of the medium steam and avoid the internal pressure of the pipe body being too high and affecting the assembly stability of the pipe body.
[0026] Furthermore, the bottom of the exhaust passage 3 is constructed as a downwardly concave arc surface. In this technical solution, the arc surface provided at the bottom of the exhaust passage functions to buffer the medium steam and guide the medium steam to the air outlet holes on both sides and discharge it into the discharge main pipe, which to a certain extent reduces the erosion of the medium steam on the pipe body and improves the assembly stability of the pipe body.
[0027] Furthermore, a step 5 is formed circumferentially on the upper part of the exhaust passage 3. An assembly space 6 is formed between the step 5 and the air inlet 2. The air outlet branch pipe 100 extends into the assembly space 6 and is fixedly welded to the pipe body 1. In this technical solution, the setting of the step makes an assembly space formed between the step and the air inlet. The air outlet branch pipe extends into the assembly space and is fixedly welded to the pipe body, which can increase the welding area between the air outlet branch pipe and the pipe body and improve the connection strength between the air outlet branch pipe and the pipe body. In addition, the end of the air outlet branch pipe can also be fixedly welded to the edge of the end of the air inlet of the pipe body, but the welding area is small and the connection strength will decrease; the connection structure can also be that the end of the air outlet branch pipe is sleeved outside the pipe body, but it will erode the entire pipe body and affect the assembly stability; besides the above methods, the connection structure can also use other effective fixed connection structural methods.
[0028] Furthermore, the side wall of the pipe body 1 is fixedly welded to the discharge main pipe 300. In this technical solution, the side wall of the pipe body is fixedly welded to the discharge main pipe, which can improve the connection strength between the discharge main pipe and the pipe body and prevent the pipe body from shaking during the discharge process.
[0029] It should also be noted here that the pipe anti-erosion device in this case, that is, the pipe body, is made of Q235 steel, which has high stability and is not easily corroded. It can also be made of other materials with relatively high stability, and it is convenient to connect with the air outlet branch pipe and the discharge main pipe. Embodiment 2:
[0030] As Figure 3 shown, a pipeline discharge system includes an air outlet branch pipe 100, a cut-off valve 200 and a discharge main pipe 300. The cut-off valve 200 is arranged on the air outlet branch pipe 100. This system also includes a pipeline anti-erosion device in Embodiment 1. It should be noted here that the best arrangement position of a pair of air outlet holes is at the horizontal midline position of the discharge main pipe, which causes the least interference to the inner walls on the upper and lower sides of the pipeline.
[0031] Embodiment 3: As Figure 4 shown, a pipeline discharge system includes an air outlet branch pipe 100, a cut-off valve 200 and a discharge main pipe 300. The cut-off valve 200 is arranged on the air outlet branch pipe 100. It also includes a pipeline anti-erosion device. The part of this device that is different from the device in Embodiment 1 is that multiple pairs of air outlet holes are longitudinally arranged on the side wall of the pipe body. These air outlet holes are horizontally arranged along the extension direction of the discharge main pipe 300, which can further increase the discharge amount of the medium steam.
[0032] In this specific embodiment, aiming at the problem that in the existing pipeline discharge system, the medium steam directly flushes onto the inner wall of the discharge main pipe. Due to the relatively high discharge pressure of the medium steam, over a long period, the side wall of the main pipe will become thinner until it is damaged and leaks, thus affecting production. The above solution is to fixedly connect a pipeline anti-scouring device at the end of the air outlet branch pipe. This device is in the shape of a short tube, with a part of the tube body extending out of the discharge main pipe, and another part of the tube body extending into the discharge main pipe and the bottom of this part being closed. Air outlet holes are provided on the side wall of this part. Therefore, the medium steam in the air outlet branch pipe comes out through the air outlet holes after passing through the exhaust channel in the tube body and is horizontally discharged, and the discharge direction is along the extension direction of the discharge main pipe, that is, the setting direction of the air outlet holes corresponds to the pipe orifice of the discharge main pipe. Thus, the discharge direction of the medium steam is changed, and no scouring at any angle will be caused to the discharge main pipe, thereby greatly prolonging the service life of the pipeline and reducing the maintenance cost.
[0033] In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
[0034] Although the embodiments of the present utility model have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present utility model. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present utility model without departing from the principles and purposes of the present utility model.
