Description

Technical Field

[0001] The utility model belongs to the technical field of oil well production, in particular to a conveying device for annular space flow-blocking and sealing particles. Background Art

[0002] The conveying device for annular flow-blocking isolation particles is a device used in oil and gas well operations. Its main function is to accurately transport specific granular materials to the target location underground to form an effective isolation and flow-blocking structure. The conveying pipeline of the conveying device is a channel connecting the surface equipment and the target location underground. It is usually made of wear-resistant materials to reduce the wear of the particles on the pipeline. During the long-term conveying process, particles may gradually accumulate on the inner wall of the pipeline, especially in areas with lower flow rates in the pipeline. Since the conveying device in the related art lacks a cleaning mechanism, the accumulation of particles in the pipeline will reduce the effective flow cross-section, resulting in increased conveying resistance.

[0032] A conveying device for annular flow-blocking and sealing particles, such as Figure 1 As shown, it includes a conveying pipe 101, a feed pipe 302, a rotating shaft, a discharge pipe 301, a spiral conveying mechanism, a driving mechanism, a cleaning mechanism, a first cover plate 201 and a second cover plate 202; the first cover plate 201 and the second cover plate 202 are symmetrically arranged at the left and right ends of the conveying pipe 101; the feed pipe 302 and the discharge pipe 301 are arranged at the left and right ends of the conveying pipe 101, the feed pipe 302 is located above the conveying pipe 101, and the discharge pipe 301 is located below the conveying pipe 101; the rotating shaft is rotatably connected to the first cover plate 201 and the second cover plate 202. The driving mechanism is used to realize the rotation of the rotating shaft;

[0033] like Figure 3As shown, the spiral conveying mechanism and the cleaning mechanism are both arranged on the inner side of the conveying pipe 101, and the spiral conveying mechanism is arranged on the rotating shaft. The spiral conveying mechanism can drive the cleaning mechanism to slide inside the conveying pipe 101. The spiral conveying mechanism includes a plurality of propeller blades 601, which are evenly arranged around the circumference of the rotating shaft. The outer edge of each propeller blade 601 is slidably connected to the cleaning mechanism. In this embodiment, the number of propeller blades 601 is four. The outer edge of the propeller blade 601 is slidably connected to the cleaning mechanism drive ring 502 via a spiral slider 602. It also includes two guide rails 102, which are symmetrically arranged on the inner wall of the conveying pipe 101 in an upper and lower manner. Each guide rail 102 is slidably engaged with the fixing ring 501 of the cleaning mechanism. The spiral conveying mechanism can continuously and stably propel the particles along the pipeline, ensuring uniform conveying and continuous operation. The spiral structure allows for effective conveying and cleaning functions in a relatively small space, making it suitable for various industrial applications with limited space. Propeller blades 601, through a sliding connection with the cleaning mechanism, simultaneously clean the pipe's interior during the conveying process, reducing the risk of particle accumulation and blockage. The rotation of propeller blades 601 is synchronized with the movement of the cleaning mechanism, ensuring that the pipe's interior is cleaned while particles are being transported, improving overall efficiency. The rotation of propeller blades 601 directly drives the cleaning mechanism, eliminating the need for additional drive devices and reducing system energy consumption and complexity.

The left and right ends of the fixed ring 501 are each provided with a fixed slot, and each fixed slot is provided with a corresponding cleaning scraper 503402. The cleaning scrapers 503402 are connected to the connecting rods via a pin. The cleaning mechanism regularly removes particles and impurities attached to the inner wall of the pipeline, reducing the risk of blockage and ensuring smooth transportation. By keeping the inner wall of the pipeline clean, frictional resistance can be reduced, thereby improving overall transportation efficiency and reducing energy consumption. Regular cleaning can prevent the long-term accumulation of particles, reduce wear and corrosion on the inner wall of the pipeline, and thus extend the service life of the equipment. The automated cleaning function reduces the frequency and difficulty of manual maintenance, reducing maintenance costs and downtime.

[0035] The driving mechanism includes a driving motor, a synchronous belt and a gear shaft 401. The output end of the driving motor is connected to the gear shaft 401 through a synchronous belt.
