Description

Technical Field

[0001] This utility model relates to the field of heat preservation device technology, specifically a chemical pipeline heat preservation treatment device. Background Technology

[0002] Pipelines are common equipment in modern life. Chemical tankers typically use pipelines to transport materials, improving transportation efficiency. While current chemical tanker pipelines generally meet basic needs, some problems remain. One issue is the lack of insulation in current chemical tanker pipelines. Due to the long transport distances, the material temperature is easily affected, reducing efficiency and overall practicality of the equipment.

[0003] A patent search revealed a patent, publication number "CN212430065U," entitled "A Chemical Tanker Pipeline with Insulated Structure." While the device in this publication addresses the aforementioned problems, it employs a protective strip and insulation layer for pipeline insulation. This method is simplistic, offers poor insulation protection, and reduces the overall insulation effectiveness of the pipeline. Therefore, this invention designs a chemical pipeline insulation treatment device to solve the aforementioned problems. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a chemical pipeline insulation device includes a pipe body 1 and an installation sleeve 2. The installation sleeve 2 is fixedly fitted onto the outside of the pipe body 1. The installation sleeve 2 is made of thermal insulation material. A connector 3 is fixedly provided at the top center inside the installation sleeve 2. An exhaust hole 4 is integrally provided at the center inside the connector 3. A clearance hole 5 is integrally provided on the left and right sides at the lower end inside the connector 3. A monitoring component 6 is provided inside the installation sleeve 2. The monitoring component 6 includes a slip ring 601 that is slidably disposed on the left and right sides inside the installation sleeve 2. The slip ring 601 is fitted onto the outside of the pipe body 1. The slip ring 601 is made of rubber. Springs 602 are fixedly provided at the front and rear ends of the outer wall of the slip ring 601. The end of the spring 602 away from the slip ring 601 is fixedly connected to the installation sleeve 2. Sliding pins 603 are fixedly provided at the upper and lower ends of the outer wall of the slip ring 601. The sliding pins 603 slide through the installation sleeve 2. A limiting block 604 is fixedly provided at the end of the sliding pin 603 away from the slip ring 601.

[0026] The exhaust port 4 is a blind hole design, and the relief hole 5 is a through hole design. The interior of the exhaust port 4 is connected to the interior of the relief hole 5. A one-way valve 7 is fixed inside the exhaust port 4. The one-way valve 7 and the relief hole 5 are offset from each other. The axis of the sliding pin 603 is parallel to the axis of the pipe body 1.

[0027] The operator first connects the output end of the existing suction device to the connector 3 via a thread. Then, by using the suction device, the gas between the mounting sleeve 2 and the tube 1 is discharged through the relief hole 5 and the exhaust hole 4, thereby creating a negative pressure attraction inside the mounting sleeve 2. At this time, the negative pressure attraction causes two slip rings 601 to move in opposite directions, that is, the slip rings 601 pull the spring 602 to deform. At the same time, the slip rings 601 drive the sliding pin 603 and the limiting block 604 to move along the direction of the mounting sleeve 2 until the limiting block 604 and the mounting sleeve 2 are in contact. At this time, the inside of the mounting sleeve 2 is in a near-vacuum state. The operator then separates the suction device from the connector 3. Through the design of the one-way valve 7, the negative pressure inside the mounting sleeve 2 can be prevented from drawing out the outside gas, ensuring the stability of the negative pressure inside the mounting sleeve 2. In the above way, a vacuum layer is formed inside the mounting sleeve 2. At this time, through the vacuum layer and the heat insulation function of the mounting sleeve 2, the tube 1 is doubly insulated. Example 2

[0028] like Figure 2 , Figure 3 , Figure 5 As shown, sealing rings 8 are fixed at the four corners inside the mounting sleeve 2. The sealing rings 8 are fitted outside the sliding pin 603. Baffles 9 are fixed on the left and right sides inside the tube body 1. The sealing plate 10 set inside the baffle 9 is rotatably connected to the tube body 1. The baffle 9 and the sealing plate 10 are made of heat insulation material. A rotating rod 11 is rotatably connected inside the baffle 9. The rotating rod 11 is fixedly inserted through the sealing plate 10. The axis of the rotating rod 11 coincides with the axis of the tube body 1. A worm gear 12 is fixedly fitted on the right side outside the rotating rod 11. The upper and lower ends of the baffle 9 are integrally provided with mounting holes 13. The front and rear ends of the sealing plate 10 are integrally provided with clearance holes 14. The mounting holes 13 and clearance holes 14 are through holes. A worm 15 is rotatably inserted through the top right side of the mounting sleeve 2. The worm 15 is inserted through the tube body 1. The worm 15 meshes with the worm gear 12. A sealing block 16 fixed on the top right side of the mounting sleeve 2 is fitted outside the worm 15.

[0029] According to the operation method in Embodiment 1, after the outer wall of the pipe body 1 is insulated, the operator can rotate the worm gear 15. The worm gear 15 controls the worm wheel 12 to drive the rotating rod 11 to rotate in conjunction with the sealing plate 10 until the clearance hole 14 at the sealing plate 10 and the mounting hole 13 at the baffle 9 are misaligned. Then, the operator can release the worm gear 15. At this time, the sealing plate 10 and the baffle 9 disconnect the inside of the pipe body 1 from the outside. At the same time, through the heat insulation design of the baffle 9 and the sealing plate 10, the inside of the pipe body 1 is insulated. In addition, the operator can rotate the worm gear 15 to rotate in conjunction with the sealing plate 10 until the clearance hole 14 and the mounting hole 13 are aligned. Then, the operator can release the worm gear 15, thereby connecting the inside of the pipe body 1 with the outside, ensuring the normal operation of the pipe body 1 in subsequent use. The sealing ring 8 seals the sliding area between the sliding pin 603 and the mounting sleeve 2, and the sealing block 16 seals the transition area between the worm gear 15 and the mounting sleeve 2.
