Description

Technical Field

[0001] The utility model belongs to the technical field of screen tubes, and in particular relates to a screen tube which is easy to clean. Background Art

[0002] During the oil production process, some formation sand will enter the wellbore with the fluid. In severe cases, it will cause the bottom of the well to collapse and bury the oil layer sand. It will also cause pump jams and oil pipe sand blockages, accelerate the corrosion and wear of casing and downhole tools, thereby affecting production, increasing the workload, and causing unnecessary increase in oil production costs. The screen is a device used to filter, separate or screen substances. It usually consists of a cylindrical frame and a component covered with a screen or sieve holes inside. When the mixture passes through the screen, smaller particles will pass through the sieve holes or screen, while larger particles will be blocked inside the screen. Screens are often used in particle separation, solid-liquid separation and screening processes in industrial production.

[0003] The traditional screen tube structure is usually composed of a single layer of screen mesh or screen holes. In some cases, this structure may not be strong enough and is prone to deformation or breakage. In order to improve the stability of the screen tube, multiple layers of screen tubes are often fixed together. This design can increase the strength and stability of the screen tube, so that it can better withstand the pressure and vibration during operation. However, too many layers may cause the structure of the screen tube to become complicated and difficult to clean. Since there are gaps between each layer of the screen tube, materials may accumulate in these gaps, making the cleaning work more cumbersome. Therefore, a screen tube that is easy to clean is needed to solve the above problems. Utility Model Content

[0006] By providing a support assembly, a bearing, a connecting ring and an inner tube assembly, the connecting ring is rotated to release the connection between the connecting ring and the guide tube, and then the wire mesh is taken out from the inside of the honeycomb tube. In this way, the wire mesh and the honeycomb tube can be easily cleaned to completely remove impurities and residues therein. The detachable screen tube structure allows each layer of the screen tube to be independently disassembled and cleaned, avoiding the accumulation of materials in the gaps of each layer, simplifying the cleaning work, and facilitating maintenance and cleaning.
