Description

Technical Field

[0001] The utility model relates to the technical field of pipeline maintenance, in particular to a circulation pipe flushing device. Background Art

[0002] The salt content in wastewater from oil and gas fields is relatively high. If high-salt wastewater is discharged directly, it may cause land salinization and soil compaction. At present, the methods for treating saline wastewater include electrodialysis, reverse osmosis, distillation, and reinjection. Among them, low-temperature multi-effect distillation technology has basically no requirements for the quality of influent water, but impurities and salt scale are easily accumulated at the lower end of the circulation pipe of the low-temperature multi-effect distillation device. After the circulation pump is removed, there are no cleaning and flushing holes on the other side of the circulation pipe, and the circulation pipe is long and has a small space, making it difficult to clean.

[0022] The utility model will be further described below in conjunction with the accompanying drawings.

[0023] like Figures 1 to 3 As shown, a circulating pipe flushing device of an embodiment of the utility model includes an adjusting rod 1, a moving mechanism 2 and a nozzle 3, one end of the adjusting rod 1 is connected to the moving mechanism 2, the nozzle 3 is arranged on the moving mechanism 2, and the adjusting rod 1 includes five detachably connected rod bodies 11.

[0024] The rod bodies 11 are connected in a detachable manner. The length of the adjusting rod 1 can be adjusted by changing the number of the rod bodies 11. The adjusting rod 1 of a suitable length is selected according to the depth of the part to be flushed. The adjusting rod 1 can be held by a person. If the depth of the part to be flushed is deep, a larger number of rod bodies 11 are selected for connection so that the nozzle 3 is close to the part to be flushed, and the nozzle 3 can be connected to a water supply pipe (not shown in the figure). If the depth of the part to be flushed is shallow, a smaller number of rod bodies 11 are selected for connection for easy operation. The moving mechanism 2 is used to contact the inside of the circulation pipe so that the nozzle 3 can reach the specified depth in the circulation pipe for flushing and remove impurities and salt scale inside the circulation pipe. The circulation pipe flushing device of this embodiment has a simple structure, low cost, high reliability, can adapt to the narrow space in the circulation pipe, and conveniently flush the inside of the circulation pipe.

[0025] Furthermore, a positioning ring 12 through which a water supply pipe passes is provided on the rod body 11. The water supply pipe adopts a hose, and the positioning ring 12 can limit the water supply pipe to prevent it from being entangled or bent at a large angle, so that the water supply flow to the nozzle 3 remains stable.

[0026] Furthermore, the positioning rings 12 are arranged at the top of the rod body 11, and the positioning rings 12 are arranged in a straight line. The positioning rings 12 are all located at the top of the rod body 11, which is convenient for passing the water supply pipe through the positioning rings 12. The positioning rings 12 are arranged in a straight line, so that the water supply pipe can basically maintain a straight state, and the flow resistance of water in the water supply pipe is small.

[0027] In this embodiment, the positioning ring 12 is arranged on the top of the rod body 11 by welding.

[0028] In other embodiments, a threaded connection column is provided on the surface of the positioning ring 12, and a threaded hole for installing the positioning ring 12 is opened on the rod body 11. The positioning ring 12 is threadedly connected to the rod body 11, which facilitates loading and unloading when the positioning ring 12 needs to be replaced.

[0029] like Figure 1 As shown, the moving mechanism 2 includes a connecting shaft 21 and rollers 22 arranged at both ends of the connecting shaft 21, and one end of the adjusting rod 1 is detachably connected to the connecting shaft 21. By pushing and pulling the adjusting rod 1, the roller 22 can roll on the inner wall of the circulation pipe, thereby conveniently changing the position of the nozzle 3.

[0030] like Figure 3 As shown, the axis of the roller 22 is at an angle to the axis of the connecting shaft 21, that is, the connecting shaft 21 is not perpendicular to the roller 22. Since the inner wall of the circulation pipe is a curved surface and not flat, this design allows the rolling surface of the roller 22 to more fully contact the inner wall of the circulation pipe, which is conducive to the stable movement of the circulation pipe flushing device.

[0031] In other embodiments, a rubber ring is wrapped around the surface of the roller 22 that contacts the inner wall of the pipe, so that the circulating pipe flushing device is not prone to slipping when moving inside the pipe, while also reducing the wear on the inner wall of the pipe.

[0032] like Figure 1 As shown, the nozzle 3 includes a connector 31 and three nozzles 32. The connector 31 is fixed on the connecting shaft 21, and one end of the nozzle 32 is connected to the connector 31. By providing more than two nozzles 32, more than two flushing water flows can be obtained, and different parts of the circulation pipe can be flushed at the same time, thereby improving the flushing efficiency.

[0033] In order to flush out the impurities and salt scale inside the circulation pipe, the water flow sprayed from the nozzle 32 is directed toward the side of the regulating rod 1 away from the connecting shaft 21, so that the water flow can carry the impurities and salt scale out from the pipe mouth, and the flushed impurities and salt scale will not enter the deep part of the circulation pipe.

[0034] In order to flush a larger area of ​​the pipe wall, the shape of the nozzle 321 of the nozzle 32 can be set to be a long strip, a wave or other shape, so that the sprayed water flow has a larger width, thereby improving the flushing efficiency of the circulation pipe.

[0035] In this embodiment, the nozzles 32 are all bent pipes. Figure 2 As shown, the nozzles 321 of the various nozzle pipes 32 face in different directions, so that the flushing range of the nozzle 3 is larger and the inside of the circulation pipe can be flushed more effectively.

[0036] Furthermore, the nozzle 32 is a flexible tube. In the present embodiment, the nozzle 32 is a stainless steel hose, which can conveniently change the direction of the nozzle 321, thereby better adapting to current operational requirements and improving flushing efficiency.

[0037] In this embodiment, the rod body 11 is a hollow structure, so that the rod body 11 has a lighter weight, which is beneficial to reducing the overall weight of the circulation pipe flushing device, thereby making it easier to operate.

[0038] Furthermore, both ends of the rod body 11 are provided with internal threads and external threads (not shown in the figure), and two adjacent rod bodies 11 are threadedly connected, so that the rod bodies 11 can be easily assembled and disassembled to quickly obtain adjustment rods 1 of different lengths.

[0039] The circulating pipe flushing device is made of aluminum alloy, which is light in weight and easy to operate. It also has strong anti-corrosion performance and is suitable for use inside the circulating pipe.

[0040] 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.
