Description

A steam transport pipeline structure for coal combustion Technical Field

[0001] This utility model relates to the field of steam transmission pipelines, and more specifically, to a structure for a steam transmission pipeline for coal combustion. Background Technology

[0002] Steam, also known as water vapor, is formed when a liquid evaporates in a confined, enclosed space. Liquid molecules pass through the liquid surface and enter the space above, becoming steam molecules. Based on the effects of pressure and temperature on various types of steam, steam is classified into saturated steam and superheated steam. The main uses of steam include heating, humidification, power generation, and driving. Steam transmission pipelines serve as the primary means of steam transport. Existing steam transmission pipelines are often fabricated into multiple sections and connected according to the specific construction requirements on site.

[0003] In related technologies, to address the problem of bolts on the outer wall of insulation structures corroding and loosening over time, patent CN219473095U provides an insulation structure and steam conveying pipeline. This involves inserting a positioning post on a ring plate into the outer protective pipe, filling the cavity between the outer protective pipe and the conveying pipe with insulation material, and then fixing a sealing ring to the outer wall of the mounting ring. The main and auxiliary fixing rings are then inserted from both sides using positioning posts and installed via fixing blocks and grooves. Fixing bolts are then inserted into the fixing holes to further secure the main and auxiliary fixing rings. Finally, sealing plugs are inserted into the fixing holes for sealing. This insulation structure further improves the sealing performance of the connection, while the sealing plugs protect the fixing bolts from rusting and loosening.

[0004] Existing steam delivery pipeline structures have the following drawbacks: Steam delivery pipelines play a crucial role in the coal combustion process. However, traditional steam delivery pipeline structures have many shortcomings, such as steam leakage, pipeline blockage, and maintenance difficulties, which seriously affect the stability and efficiency of the coal combustion system. In view of this, we propose a steam delivery pipeline structure for coal combustion. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a steam conveying pipeline structure for coal combustion, aiming to improve the technical problems that traditional steam conveying pipeline structures have many deficiencies, such as steam leakage, pipeline blockage, and maintenance difficulties, which seriously affect the stability and efficiency of coal combustion systems.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a steam conveying pipeline structure for coal combustion, comprising: a first connecting pipe, a second connecting pipe, a first limiting ring, and an installation sleeve. The first connecting pipe and the second connecting pipe are connected in a butt joint. A butt joint protrusion is fixedly installed on the top of the second connecting pipe, and a butt joint groove corresponding to the butt joint protrusion is provided on the bottom of the first connecting pipe. The first and second connecting pipes are fitted with the first and second limiting rings respectively. An installation plate is movably installed on the top of the second limiting ring via a connecting seat. A threaded rod is rotatably installed on one side of the installation plate, and a threaded sleeve is threadedly installed on the outer side of the threaded rod. A fixing block that mates with the threaded sleeve is fixedly installed on the top of the first limiting ring. An installation sleeve is fixed on one side of the first connecting pipe. A fixing sleeve communicating with the first connecting pipe is provided on the inner side of the installation sleeve. A connecting ring is movably connected to the inside of the installation sleeve via a telescopic rod. A fixing plate is fixedly installed inside the fixing sleeve. A movable rod is movably installed inside the fixing plate. A plug is fixedly installed at one end of the movable rod. A conical hole corresponding to the plug is provided on the inner side of the fixing sleeve.

[0008] Preferably, a sealing ring is fixedly installed inside the second connecting pipe, and a sealing ring corresponding to the sealing ring is provided inside the first connecting pipe.

[0009] By adopting the above technical solution, during the process of the first connecting pipe and the second connecting pipe being connected to each other, the sealing ring and the sealing ring can be connected to each other, which can increase the sealing effect during the connection process and prevent leakage.

[0010] Preferably, the bottom of the first connecting pipe is fixedly installed with a mating groove, and the top of the second connecting pipe is provided with a limiting rod corresponding to the mating groove.

[0011] By adopting the above technical solution, the mutual cooperation between the docking groove and the limiting rod makes the installation of the first connecting pipe and the second connecting pipe more convenient and the docking process more accurate.

[0012] Preferably, the first limiting ring and the second limiting ring are movably connected by a connecting shaft, and an extrusion plate is fixedly installed on the inner side of the first limiting ring and the second limiting ring, and an adhesion edge that fits against the extrusion plate is provided on the outer side of the first limiting ring and the second limiting ring.

[0013] By adopting the above technical solution, the first limiting ring and the second limiting ring are installed in the gap between the first connecting pipe and the second connecting pipe. The first limiting ring and the second limiting ring can further limit the movement. With the help of the extrusion plate, the outer edges of the first limiting ring and the second limiting ring can be better fitted, increasing the tightness.

[0014] Preferably, the fixing block is provided with an installation groove, the inner side of the threaded sleeve is provided with a mating block that mates with the installation groove, and a swivel plate is fixedly installed at one end of the threaded rod.

[0015] By adopting the above technical solution, the threaded rod can be rotated along one side of the mounting plate by rotating the plum blossom disc, which can make the mating block and the mounting groove engage. The threaded sleeve can be used to push the fixing blocks together, making it more convenient to use.

[0016] Preferably, the fixed sleeve is provided with a sliding groove that mates with the connecting ring, the connecting ring is fixedly connected to both sides of the plug, and a spring is compressed and installed on the outer side of the movable rod.

[0017] By adopting the above technical solution, the telescopic rod can extend and retract, allowing the connecting ring to slide along the inner side of the sliding groove. This allows the plug installed on the inner side of the connecting ring to slide along the inner side of the fixed sleeve, thus separating the plug from the tapered hole.

[0018] The beneficial effects of this utility model are:

[0019] This application, through the mutual cooperation of a mating protrusion, a limiting rod, a first limiting ring, a second limiting ring, a threaded sleeve, and a fixing block, facilitates the installation of the sealing ring via the mating protrusion during the docking process between the first and second connecting pipes. This allows for easy docking between the sealing rings, achieving a sealing operation. Simultaneously, the first and second limiting rings are installed at the gap between the first and second connecting pipes, further limiting their position. Rotating the swivel disc allows the threaded rod to rotate along one side of the mounting plate, enabling the mating block to engage with the mounting groove. The threaded sleeve pushes the fixing block, thereby sealing the first and second limiting rings.

[0020] This application utilizes a connecting ring, a telescopic rod, a plug, a tapered hole, and a movable rod in a coordinated manner. The telescopic rod's extension and retraction allow the connecting ring to slide along the inner side of the sliding groove, thereby allowing the plug installed inside the connecting ring to slide along the inner side of the fixed sleeve. This separates the plug from the tapered hole, effectively relieving the pressure generated inside the first connecting pipe. Attached Figure Description
