Description

Technical Field

[0001] The utility model relates to the technical field of natural gas exploitation, in particular to a pipeline anti-blocking structure. Background Art

[0002] With the development of the natural gas industry, the area of ​​natural gas mining has been continuously expanded, and the output of natural gas has been greatly increased. However, the output of wastewater, namely formation water, generated in the process of natural gas mining has also been increasing. Since various salts and minerals in the formation will be brought out in the gas layer during mining, the formation water generated in the process of natural gas mining contains a large amount of sodium, potassium, chlorine and other ions. At present, low-temperature multi-effect distillation is often used to distill out the salt components in the formation water for utilization.

[0003] In the formation water cryogenic distillation system, crystal separation is at the end of the system process. The crystals still contain some water just after centrifugal separation, which greatly enhances the adhesion of the crystals. As the transmission pipeline at the separation port is used for a longer time, the surface will be worn by crystals and dense scratches will appear. Under the action of scratches and water, the friction becomes stronger, making it easier for crystals to adhere to the pipe wall, and they become larger and larger and finally block the transmission pipe section. Utility Model Content

[0004] The utility model provides a pipeline anti-blocking structure, which can remove crystals attached to the inner wall of the pipeline through the rotation of a sweeping bar, thereby preventing the pipeline from being blocked.

[0005] The utility model provides a pipeline anti-blocking structure, comprising:

[0006] A connecting piece, the connecting piece is connected to the pipeline;

[0007] at least one sweep bar, one end of which is connected to the connector, and the sweep bar is located inside the pipe; and

[0029] The utility model will be further described below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 3 As shown, the pipeline anti-blocking structure of one embodiment of the utility model includes a connecting member 1, a pipeline 2, a sweeping strip 3 and a driving mechanism 4, the connecting member 1 is connected to the pipeline 2, one end of the sweeping strip 3 is connected to the connecting member 1 and is located inside the pipeline 2, and the driving mechanism 4 is connected to the connecting member 1 to drive the connecting member 1 and the sweeping strip 3 to rotate.

[0031] The sweeping bar 3 is arranged inside the pipe 2. When the driving mechanism 4 drives the connecting member 1 to rotate, the sweeping bar 3 rotates inside the pipe 2 and whips the inner wall of the pipe 2 to sweep away the crystals attached to the inner wall of the pipe 2, thereby preventing excessive crystals from clogging the pipe 2. The overall structure is simple, reliable and low-cost. The number of sweeping bars 3 is not limited to one. In other embodiments, the number of sweeping bars 3 is two or more.

[0032] The sweep bar 3 can be made of metal, such as stainless steel, so that the sweep bar 3 has strong toughness and good corrosion resistance, and can effectively remove the crystals attached to the inner wall of the pipe 2. The sweep bar 3 should have good flexibility and be easy to bend, so that it is not easy to scratch the inner wall of the pipe 2. Due to its strong deformation ability, it can also reduce the occurrence of the sweep bar 3 being stuck.

[0033] Furthermore, the sweep bar 3 can be made of metal and covered with a polymer on its surface, for example, a layer of polytetrafluoroethylene is wrapped on the surface of stainless steel, and the properties of polytetrafluoroethylene are used to improve the wear resistance and corrosion resistance of the sweep bar 3, thereby increasing the service life of the sweep bar 3.

[0034] The sweep bar 3 will directly contact and rub against the crystal, and the force direction thereof will constantly change. Since only one end of the sweep bar 3 is fixed and fixed to the connector 1, the connection between the sweep bar 3 and the connector 1 needs to be very firm, and the sweep bar 3 and the connector 1 should be rigidly connected to ensure that the sweep bar 3 will not loosen. Specifically, the sweep bar 3 and the connector 1 are welded.

[0035] The length of the sweep bar 3 should be greater than the length of the pipe 2. Since the sweep bar 3 is relatively soft, Figure 2 As shown, it is bent inside the pipe 2. In order to enable the sweeping bar 3 to sweep away as many crystals on the inner wall of the pipe 2 as possible, the length of the sweeping bar 3 should be greater than the length of the pipe 2 so that it can completely sweep the inner wall of the pipe 2.

[0036] like Figure 3 As shown, the connecting member 1 includes a gear ring 11 and an annular wall 12 disposed on one side of the gear ring 11, the annular wall 12 is inserted into the pipe 2, and the outer wall of the annular wall 12 is connected to the inner wall of the pipe 2. The connecting member 1 is connected to the pipe 2 through the annular wall 12, and the gear ring 11 is located outside the pipe 2 to be connected to the driving mechanism 4.

[0037] like Figure 4 and Figure 5 As shown, the inner wall of the pipe 2 is provided with a first positioning groove 100, and the surface of the annular wall 12 is provided with a first positioning protrusion 121, and the first positioning protrusion 121 is inserted into the first positioning groove 100, so that the connector 1 can rotate on the pipe 2 without being loosened, and the assembly and disassembly of the connector 1 is very convenient. The connector 1 can be fixed by pushing it into the pipe 2 with force, and when the connector 1 needs to be taken out, it can be done by pulling the connector 1 outward with force.

[0038] Furthermore, in order to reduce friction when the connector 1 rotates, the groove wall of the first positioning groove 100 and the surface of the first positioning protrusion 121 can be sprayed with lubricating material, such as polytetrafluoroethylene, to achieve lower friction by utilizing the self-lubricating property of polytetrafluoroethylene.

[0039] like Figure 6 and Figure 7 As shown, in another embodiment, the inner wall of the pipe 2 is provided with a second positioning protrusion 21, the surface of the annular wall 12 is provided with a second positioning groove 200, and the second positioning protrusion 21 is inserted into the second positioning groove 200. This structural form can also fix the connector 1 on the pipe 2 and enable the connector 1 to rotate on the pipe 2.

[0040] like Figure 3 As shown, the driving mechanism 4 includes a motor 41 and a gear 42, the gear 42 is connected to the output end of the motor 41, and the gear 42 is meshed with the ring gear 11. The motor 41 drives the gear 42 to rotate, and the gear 42 drives the connecting member 1 to rotate, thereby realizing the rotation of the sweeping strip 3. The overall structure is simple and reliable, and it can work as long as it is connected to a power source.

[0041] Furthermore, the driving mechanism 4 further includes a reducer 43, the reducer 43 is connected to the output end of the motor 41, and the gear 42 is connected to the reducer 43. The reducer 43 can increase the torque of the gear 42, thereby making the sweeping strip 3 less likely to be stuck.

[0042] exist Figure 1 In the embodiment shown, the drive mechanism 4 is fixed to the outer surface of the pipe 2. Specifically, the drive mechanism 4 can be fixed to the outer surface of the pipe 2 by welding, bonding or other forms of connection, so that the gear 42 can always maintain a meshing state with the ring gear 11.

[0043] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
