Description

Technical Field

[0001] The utility model relates to the technical field of pipeline sealing, in particular to a pipeline sealing structure of a SIC membrane device. Background Art

[0002] SIC membranes are widely used in oil-water separation, particularly for treating oily wastewater from industrial processing and cleaning, oily wastewater from ship bilges, and oily wastewater from the petroleum and solid fuel thermal processing industries. Their filtration accuracy, typically ranging from 0.01 to 10 μm, effectively separates emulsified oil-water mixtures, exhibits hydrophilic and oleophobic properties, and can operate stably in strong acid, alkaline, and high-temperature environments. However, during use, SIC membranes direct the treated liquid through pipelines for treatment. This allows the transported medium to penetrate the pipe joints, where long-term reaction can lead to a loss of sealing and leakage, posing a potential safety hazard. Therefore, the sealing of pipeline joints is closely linked to production safety.

DETAILED DESCRIPTION

[0020] First of all, it should be noted that in the various embodiments described, identical components are provided with identical reference numerals or identical component names, wherein the disclosure contained throughout the entire description can be transferred to the same components having the same reference numerals or identical component names. Positional designations selected in the description, such as top, bottom, lateral, etc., also refer to the directly described and illustrated figures and are transferred to the new position in the event of a change in position.

[0021] A pipeline sealing structure of a SIC membrane device, such as Figure 1-Figure 5As shown, it includes a pipe 1, a sealing sleeve 2, a telescopic sleeve 3, a threaded sleeve 4, a pressure sleeve 5, a sealing nut 51, a pressure elastic plate 6, a sealing rubber sleeve 7, a connecting sleeve 8, a telescopic connecting rod 9 and an observation window 17. The number of pipes 1 is two, and the two pipes 1 are divided into an upper pipe 1 and a lower pipe 1. The outer wall of the upper pipe 1 is fixedly connected with a sealing sleeve 2, and the outer wall of the lower pipe 1 is slidably connected with a telescopic sleeve 3. The telescopic sleeve 3 is slidably connected to the sealing sleeve 2. The outer wall of the sealing sleeve 2 and the outer wall of the telescopic sleeve 3 are both connected with at least one threaded sleeve 4. The number of threaded sleeves 4 on the outer wall of the sealing sleeve 2 is one, and the number of threaded sleeves 4 on the outer wall of the telescopic sleeve 3 is two. The three threaded sleeves 4 are divided into an upper threaded sleeve 4, a middle threaded sleeve 4 and a lower threaded sleeve 4. The threaded sleeve The tubes 4 are all threadedly connected with sealing nuts 51, and the outer walls of the sealing nuts 51 are fixedly connected with pressure sleeves 5. The inner diameter of the pressure sleeves 5 away from the pressure elastic plate 6 is smaller than the inner diameter of the side close to the pressure elastic plate 6. The outer walls of the threaded sleeves 4 are all threadedly connected with the pressure elastic plate 6, and the inner walls of the pressure elastic plate 6 are fixedly connected with sealing rubber sleeves 7. Three connecting sleeves 8 are fixedly connected to the bottom of the upper sealing nut 51, and three telescopic connecting rods 9 are connected to the lower sealing nut 51. The connecting sleeves 8 are slidably connected to the corresponding telescopic connecting rods 9 respectively. A transparent observation window 17 is fixedly connected to the sealing sleeve 2. The transparent observation window 17 can be used to observe the sealing area through the observation window 17, and the seepage and leakage inside the sealing area can be controlled in time, so that the operator can intervene and deal with it in time.

[0022] When it is necessary to seal the upper pipe 1 with the lower pipe 1, the sealing sleeve 2 is moved upward and sleeved on the outer wall of the upper pipe 1, and then the telescopic sleeve 3 is slid to control the distance between it and the sealing sleeve 2, so that the telescopic sleeve 3 is sleeved on the outer wall of the lower pipe 1, thereby being able to dock the pipes 1 with too large a distance between the upper and lower ends, thereby improving the applicability of the sealing structure. When the two sealing nuts 51 on the telescopic sleeve 3 are rotated, the lower sealing nut 51 drives the sealing nut 51 on the sealing sleeve 2 to reverse through the connecting sleeve 8 and the telescopic connecting rod 9, so that the pressure sleeve 5 is close to The pressure-applying elastic plate 6 is squeezed and the inner diameter of the pressure-applying elastic plate 6 is squeezed and reduced, so that the sealing rubber sleeves 7 at different positions are respectively close to the upper pipe 1, the lower pipe 1 and the sealing sleeve 2. The upper sealing rubber sleeve 7 can seal the sealing sleeve 2 and the upper pipe 1, the middle sealing rubber sleeve 7 can seal the sealing sleeve 2 and the telescopic sleeve 3, and the lower sealing rubber sleeve 7 can seal the telescopic sleeve 3 and the lower pipe 1. The connecting sleeve 8 and the telescopic connecting rod 9 can improve the rotational sealing efficiency of the sealing nut 51 and achieve rapid sealing.

[0023] like Figure 1As shown, it also includes a fixing seat 10, a locking screw 11 and a positioning sleeve 12. The outer wall of the connecting sleeve 8 is fixedly connected to the fixing seat 10, and the outer wall of the fixing seat 10 is threadedly connected to the locking screw 11. The outer wall of the sealing sleeve 2 is fixedly connected to the positioning sleeve 12, and the positioning sleeve 12 is made of rubber. When the sealing nut 51 is rotated to the tightest degree, the locking screw 11 is screwed into the fixing seat 10, so that the locking screw 11 squeezes the positioning sleeve 12, thereby fixing the connecting sleeve 8 under the squeezing action of the locking screw 11. When the liquid flows in the upper end pipe 1 and the lower end pipe 1, it can prevent the vibration generated by the liquid flow from loosening the sealing nut 51, thereby improving the stability of the sealing structure.

[0024] like Figure 1 、 Figure 4 and Figure 5 As shown, it also includes a ring gear 13, a gear 14, a pressure plate 15 and a positioning screw 16. The ring gear 13 is fixedly connected between the connecting sleeve 8 and the telescopic connecting rod 9. The ring gear 13 is rotatably connected to the sealing sleeve 2 and the telescopic sleeve 3. The outer walls of the sealing sleeve 2 and the telescopic sleeve 3 are rotatably connected to three gears 14, and the gears 14 are engaged with the ring gear 13. The outer walls of the sealing sleeve 2 and the outer walls of the telescopic sleeve 3 are slidably connected to three pressure plates 15. The pressure plates 15 extend into the interior of the sealing sleeve 2 and the interior of the telescopic sleeve 3. The side of the pressure plate 15 away from the pipe 1 is threadedly connected to a positioning screw 16, and the positioning screw 16 is fixedly connected to the gear 14.

[0025] When the sealing nut 51 is rotated, the connecting sleeve 8 and the telescopic connecting rod 9 rotate along with the sealing nut 51, causing the ring gear 13 to rotate. Under the meshing action of the ring gear 13 and the gear 14, the positioning screw 16 rotates synchronously, and the pressure plate 15 slides close to the upper and lower end pipes 1. Under the squeezing action of the pressure plate 15, the sealing sleeve 2 and the telescopic sleeve 3 can be fixed to the upper end pipe 1 and the lower end pipe 1 respectively, further improving the stability of the sealing structure, and can also share the vibration external force on the sealing rubber sleeve 7, thereby extending the service life of the sealing rubber sleeve 7.
