Description

Technical Field

[0001] The invention relates to the technical field of pipeline insulation, and in particular to a thermal insulation device for a thermal resource transmission pipeline. Background Art

[0002] Thermal resource transmission pipelines, usually referred to as long-distance thermal transmission pipelines or thermal transmission pipelines, are important engineering facilities for achieving heat energy transfer. Thermal transmission pipelines are used to transmit the heat energy generated by the boiler room to the various heat-using units in the heating system through pipelines. Their main transmission media are hot water, steam, etc. Long-distance pipelines generally refer to heat transmission pipelines with a pipeline length of more than 1 km. Commonly used materials for thermal pipelines include seamless steel pipes and welded steel pipes, which should have the characteristics of high pressure and high temperature resistance. Thermal resource transmission pipelines are widely used in urban thermal transmission, hot spring hotel water supply, oil transportation, food, medicine, waste treatment and chemical industries. Since thermal pipelines are affected by high temperature, high pressure and fast flow rate during transmission, special attention should be paid to the safety of materials, expansion compensation, supports and hangers, slopes, drainage, drainage, and venting to ensure the safety of the pipeline. Among them, insulation devices are required to insulate the outside of the thermal resource transmission pipeline.

[0003] For example, the Chinese patent "An insulation device for a fluff steam delivery pipeline" with announcement number CN214789814U includes a pipeline, a plurality of insulation cotton tubes sleeved on the outer wall of the pipeline, and a cut-off opening on the insulation cotton tube. A connecting device is provided between two adjacent insulation cotton tubes. The connecting device includes an annular frame symmetrically sleeved on both sides of the insulation cotton tube, an annular groove matching the insulation cotton tube is provided on the annular frame, and a symmetrical sliding connection with abutment against the insulation cotton tube is provided on the side wall of the annular groove. The limiting gasket is provided on the annular frame, and a plurality of extrusion components for extruding the limiting gasket are provided on the annular frame. A connecting component is also provided between two adjacent annular frames. The thermal insulation cotton tube is also provided with a closing component for closing the cut-off port. A plurality of threaded holes connected to the annular groove are provided on the outer side wall of the annular frame. The extrusion component includes a plurality of screws passing through the annular frame, and the screws are threadedly connected to the threaded holes. An arc-shaped screw matched with the limiting gasket is connected to one end of the screw. A pressure plate, a screw block is connected to one end of the screw rod away from the arc-shaped pressure plate, the connecting assembly includes a connecting ring symmetrically connected between two adjacent annular frames, arc plates are symmetrically abutted on the two adjacent connecting rings, connecting plates are symmetrically connected on both sides of the arc plate, a circular hole is passed through the connecting plate, a bolt matching the circular hole is passed through the connecting plate, a nut is threadedly connected to the bolt, a first limiting groove is provided on the outer side wall of the connecting ring, and a side of the arc plate facing the connecting ring is provided with a nut matching the first limiting groove The sealing component includes a thermal insulation cotton layer connected to the outer wall of the thermal insulation cotton tube and a Velcro arranged between the thermal insulation cotton layer and the thermal insulation cotton tube. A plurality of sliders are arranged on one side of the limiting gasket, and a plurality of slide grooves matching with the sliders are opened on the side wall of the annular frame. A second limiting strip is also arranged on one side of the limiting gasket, and a second limiting groove matching with the second limiting strip is opened on the thermal insulation cotton tube. A heat-resistant rubber strip is arranged on the side of the annular frame abutting against the pipe.

[0004] Although the above-mentioned prior art can achieve the insulation of the pipeline, in actual use, on the one hand, the insulation device is easy to increase the weight of the conveying pipeline. After the insulation device is installed on the outside of the conveying pipeline, it is easy to increase the weight of the conveying pipeline, resulting in an increase in the weight of the conveying pipeline, which is easy to cause the conveying pipeline to break or be damaged. On the other hand, the installation and positioning of the insulation device is not convenient enough. When installing the insulation device, the two insulation plates need to be aligned and then fixed with bolts, which makes the positioning steps cumbersome. Therefore, it does not meet the existing needs. In this regard, we propose an insulation device for thermal resource transmission pipelines. Summary of the invention

[0014] Preferably, rubber pads are fixedly provided on the lower end of the bolt cap and the upper end of the nut, and the rubber pads are in contact with the first mounting seat and the second mounting seat respectively.

[0015] Preferably, the lower insulation board and the upper insulation board are both provided with insulation layers inside, and the lower insulation board and the upper insulation board located inside the insulation layers are both provided with heat insulation layers inside.

[0017] Preferably, a conveying pipeline is provided between the lower insulation board and the upper insulation board, and both the lower insulation board and the upper insulation board are in contact with the outer wall of the conveying pipeline.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention can support the insulation device through the hydraulic expansion device and the damper. When the insulation device is installed, the base together with the lower insulation board is placed directly under the conveying pipe. At this time, the hydraulic expansion device is turned on to extend the expansion end of the hydraulic expansion device. When the expansion end of the hydraulic expansion device is extended, the lower insulation board and the base are lifted together until the lower end surface of the lower insulation board is lifted to contact with the lower end of the conveying pipe. At this time, the expansion end of the hydraulic expansion device is continued to be extended to make the lower end surface of the lower insulation board close to the conveying pipe. At the same time, the damper and the support spring are compressed and deformed. When the conveying pipe vibrates, the damper and the support spring absorb the vibration on the pipe by deformation, so as to avoid the conveying pipe connection from loosening when the conveying pipe vibrates. At the same time, the hydraulic expansion device provides certain support to the pipe, thereby improving the stability of the conveying pipe.

[0020] The first mounting seat and the second mounting seat are then tightened by the nut and the bolt, so that the lower thermal insulation board and the upper thermal insulation board are closely attached to the outer wall of the conveying pipe, thereby simplifying the positioning and installation process of the thermal insulation device and improving the installation efficiency of the thermal insulation device.

[0021] 3. The present invention can protect the insulation layer through the insulation layer and the waterproof layer. When the insulation device encounters rainfall, the waterproof layer arranged inside the lower insulation board and the upper insulation board can prevent rainwater from penetrating into the insulation layer, so that the insulation device can be used in different environments. When thermal resources such as steam or hot oil are transported in the conveying pipeline, the pipe wall temperature of the conveying pipeline rises rapidly. At this time, the pipe wall is in direct contact with the lower insulation board and the upper insulation board, and the high temperature on the pipe wall is transferred to the lower insulation board and the upper insulation board. The high temperature on the pipe wall is isolated by the insulation layer arranged inside the lower insulation board and the upper insulation board to prevent the high temperature from being transferred to the insulation layer, thereby protecting the insulation layer and extending the service life of the insulation layer.

[0038] See also Figure 1 and Figure 4 The lower end of the bolt cap 15 and the upper end of the nut 17 are fixedly provided with a rubber pad 16, and the rubber pad 16 is in contact with the first mounting seat 8 and the second mounting seat 9 respectively, so as to prevent the nut 17 from loosening due to long-term fixation through the rubber pad 16.

[0039] See also Figure 2 and Figure 5 The lower insulation board 6 and the upper insulation board 7 are both provided with an insulation layer 19 inside, and the lower insulation board 6 and the upper insulation board 7 are both provided with an insulation layer 18 inside the insulation layer 19, wherein the insulation layer 18 is filled with polyurethane foam, so that the insulation layer 19 can be thermally insulated and protected by the insulation layer 18.

[0042] Working principle: When installing the upper insulation board 7, the lower insulation board 6 has been fixed. First, place the upper insulation board 7 on the upper end of the conveying pipe 22. Then push the upper insulation board 7 to slide on the conveying pipe 22 until the upper insulation board 7 is slid to the opening of the limit strip 11 and the limit groove 10. Continue to push the upper insulation board 7 to slide the limit strip 11 into the limit groove 10 until the first bolt hole 12 on the first mounting seat 8 and the second bolt hole 13 on the second mounting seat 9 are aligned. Then, align the bolt 14 with the opening position of the first bolt hole 12 and push it into the first bolt hole 12.

When the heat preservation device encounters rainfall, the waterproof layer 20 arranged inside the lower heat preservation board 6 and the upper heat preservation board 7 can prevent rainwater from penetrating into the heat preservation layer 19, so that the heat preservation device can be used in different environments.

The heat insulation layer 18 arranged inside the lower heat preservation board 6 and the upper heat preservation board 7 isolates the high temperature on the pipe wall, prevents the high temperature from being transferred to the heat preservation layer 19, protects the heat preservation layer 19, and thus prolongs the service life of the heat preservation layer 19.
