Description

Technical Field

[0001] The utility model relates to the technical field of heat-insulated pipelines, in particular to a high-temperature steam steel jacketed steel nano-aerogel heat-insulated pipeline. Background Art

[0002] The steel-in-steel steam insulated pipe is composed of an outer protective steel pipe, a steel pipe anti-corrosion and insulation layer, and an inner working steel pipe. The steel-in-steel high-temperature steam insulated pipe is exposed to high-temperature gas for a long time, which causes rust and impurities on the inner wall, affecting the normal insulation quality. Therefore, a high-temperature steam steel-in-steel nano-aerogel insulated pipe is needed.

[0003] According to the description of the steel-in-steel high-temperature steam insulated pipeline disclosed on the patent website (authorization announcement number: CN 208816974U), "The utility model discloses a steel-in-steel high-temperature steam insulated pipeline, including a pipeline body, and mounting grooves are provided on the inner walls on both sides of the left and right sides of the pipeline body. The inner surfaces of the two mounting grooves on the side away from each other are fixedly connected with mounting bearing seats, and the inner surfaces of the two mounting bearing seats on the side close to each other are fixedly connected with a rotating rod, and the outer surface of the rotating rod is fixedly connected with an impeller, and the outer surface of the rotating rod is fixedly connected with an active tooth block located on the side of the impeller close to the mounting groove. The utility model sets an impeller to play the role of pulling the rotating rod to rotate during the high-temperature steam transportation, and the rotation of the impeller controls the rotating rod to pull the active tooth block to rotate. The driven tooth plate and the cleaning plate are set to play the role of cleaning the inner wall of the insulation pipeline with the transportation of high-temperature steam as the power, and then the inner wall of the insulation pipeline is cleaned in a timely and effective manner to improve the quality and service life."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model sets an impeller to pull the rotating rod to rotate when high-temperature steam is transported, and the rotation of the impeller controls the rotating rod to pull the active gear block to rotate. The driven gear plate and the cleaning plate are set to clean the inner wall of the insulation pipe with the transportation of high-temperature steam as the power. However, in actual use, the rotation of the impeller of the device controls the rotating rod to pull the active gear block to rotate, and the rotation of the active gear block pulls the driven gear plate to change its position. However, when the flow direction of water remains unchanged, the driven gear plate will not move after moving to a certain position, thereby failing to drive the cleaning plate to clean the inner wall of the pipe body. When cleaning, the water flow direction needs to be alternately changed so that the cleaning plate can move up and down to clean the inner wall of the pipe body. When cleaning, the device cannot transport the liquid to be transported, so it is necessary to improve a high-temperature steam steel-jacketed steel nano-aerogel insulation pipe to solve the above problems.

The number of the bolts A is four, and the bolts A are threadedly installed inside the spiral twisted pieces. The spiral twisted pieces are arranged inside the insulation pipe, so that the water flow is disturbed, and the water flow is close to a fully turbulent state, making it difficult for easily sticky substances in the water to adhere to the inner wall of the insulation pipe.

[0011] Preferably, the anti-blocking component includes two rotating rods, which are respectively fixedly installed on the outside of two rotating shafts A, and two springs are fixedly installed inside the two rotating rods.

[0016] 1. The high-temperature steam steel-jacketed steel nano-aerogel insulated pipe has an anti-clogging mechanism. During use, the spiral twisting piece rotates to disturb the water flow. The strongly rotating water flow generates friction and shear force on the inner wall of the insulation pipe, which destroys the adhesion mechanism of sticky substances in the water on the inner wall of the insulation pipe, making it difficult for sticky substances in the water to adhere to the inner wall of the insulation pipe. The scraper rod always adheres to the inner wall of the insulation pipe under the action of the spring, scrapes off the trace sticky substances that may adhere to the inner wall of the insulation pipe, and discharges them with the water flow, so that the inside of the insulation pipe remains unobstructed.

[0029] The anti-blocking mechanism 5 includes a power assembly 51 and an anti-blocking assembly 52 , and the anti-blocking assembly 52 is arranged outside the power assembly 51 .

[0030] Furthermore, the power assembly 51 includes three limiting cross rods 511, and the three limiting cross rods 511 are respectively fixedly installed inside the mounting tube A2, the mounting tube B3 and the mounting tube C4. The three limiting cross rods 511 are internally rotatably installed with a rotating shaft A512, the interior of the rotating shaft A512 is provided with a spiral twisting piece 513, the internal thread of the rotating shaft A512 is installed with a bolt A514, and the outside of the rotating shaft A512 is fixedly installed with an impeller 515, which drives the rotating shaft A512 to rotate under the action of water flow, and uses water flow as a power source, which is more convenient.

[0031] Furthermore, there are two rotating shafts A512, and the spiral twisted pieces 513 are arranged inside the two rotating shafts A512. There are four bolts A514, and the bolts A514 are threadedly installed inside the spiral twisted pieces 513. The spiral twisted pieces 513 are arranged inside the insulation pipe 1, so that the water flow is disturbed, and the water flow is close to a fully turbulent state, making it difficult for easily sticky substances in the water to adhere to the inner wall of the insulation pipe 1.

[0032] Furthermore, the anti-blocking component 52 includes two rotating rods 521, which are respectively fixedly installed on the outside of the two rotating shafts A512, and two springs 522 are fixedly installed inside the two rotating rods 521. A mounting block 523 is fixedly installed on one end of the spring 522 away from the rotating rod 521, and sliders 524 are fixedly installed on the left and right of the mounting block 523. A scraper rod 525 is fixedly installed on the side of the mounting block 523 away from the rotating rod 521 to scrape off trace amounts of easily sticky substances that may adhere to the inner wall of the insulation pipe 1.

[0033] Furthermore, the scraper rod 525 contacts the inner wall of the insulation pipe 1 , the mounting block 523 is slidably installed inside the rotating rod 521 , and the slider 524 is slidably installed inside the rotating rod 521 to limit the movement of the mounting block 523 .

[0034] Embodiment 2:

[0035] See also Figure 5, and combined with Example 1, it is further obtained that the filtering mechanism 6 includes a flange A61, the flange A61 is fixedly installed on the outside of the mounting tube C4, a filter tube 62 is arranged on the left side of the mounting tube C4, a flange B63 is fixedly installed on the outside of the filter tube 62, a filter screen 64 is fixedly installed inside the filter tube 62, a rotating shaft B65 is rotatably installed inside the filter screen 64, a scraper 66 is fixedly installed on the left end of the rotating shaft B65, two sealing rings 67 are arranged on the outside of the flange B63, and a bolt B68 is installed on the internal thread of the sealing ring 67, and the two sealing rings 67 are installed on the flange B63 and the outside of the flange A61.

[0036] Furthermore, there are two bolts B68, and both bolts B68 are threadedly installed inside two sealing rings 67. The two sealing rings 67 are arranged on the outside of the filter tube 62. The end of the rotating shaft B65 away from the scraper 66 is fixedly installed with the rotating shaft A512. The scraper 66 contacts the filter screen 64 to scrape off impurities adhered to the surface of the filter screen 64.

[0037] In actual operation, when the device is used, water enters the filter tube 62, and the filter screen 64 pre-filters the water, making the water cleaner and the inside of the insulation tube 1 tidier. The filtered water passes through the filter mechanism 6 and the installation tube C4 and enters the installation tube B3. The impact of the water flow causes the impeller 515 to rotate, and the impeller 515 drives the rotating shaft A512 to rotate, thereby driving the spiral twisted blade 513 to rotate, causing the water flow to be disturbed, making the water flow close to a fully turbulent state. The strongly rotating water flow generates friction and shear force against the inner wall of the insulation tube 1, destroying the adhesion mechanism of the easily sticky substances in the water on the inner wall of the insulation tube 1, making it difficult for the easily sticky substances in the water to adhere to the inner wall of the insulation tube 1. The rotating shaft A512 drives the rotating shaft B65 to rotate, and the rotating shaft B65 drives the scraper 66 to rotate, and the scraper 66 scrapes off the impurities adhered to the surface of the filter screen 64 to prevent the impurities from clogging the filter screen 64. The two sealing rings 67 seal the flange B63 and the flange A61 under the action of the two bolts B68, so that the filter tube 62 can be installed more compactly to prevent water leakage. The rotating shaft A512 drives the rotating rod 521 to rotate, so that the mounting block 523 drives the scraper rod 525 to rotate, and the scraper rod 525 scratches the inner wall of the insulation tube 1. The spring 522 always exerts a force on the mounting block 523 toward the inner wall of the insulation tube 1, so that the scraper rod 525 always fits the inner wall of the insulation tube 1. The slider 524 limits the movement of the mounting block 523, and the scraper rod 525 scrapes off the trace amount of easily sticky substances that may adhere to the inner wall of the insulation tube 1.
