The separator includes a housing, with a support assembly fixedly installed at the right end of the housing's inner cavity. The support assembly has an installation assembly at its right end, and rotating assemblies at both its upper and lower ends. This invention uses a drive assembly to drive a rack and pinion to move the connecting rod as a whole, which in turn drives a rack and pinion to rotate the gear ring and nut. The nut engages with the three connecting pipes of the steam-water separator. Unscrewing the nut from the connecting pipes separates the fixed pipe and the nut from the steam-water separator. Rotating the rotating sleeve then directly sends out the placement ring and the steam-water separator. The steam-water separator can be hooked out from the outside using a tool. During replacement, personnel do not directly contact the steam-water separator, and the entire housing does not require shutdown, saving the cooling and reheating time required in existing technologies and improving production efficiency.

Description

Technical Field

[0001] This invention relates to the field of steam generator technology, and more specifically, to a contaminant-resistant steam-water separator for use in industrial boiler steam generators. Background Technology

[0002] The industrial boiler steam generator is the core heat exchange and evaporation equipment in an industrial boiler system. Its core function is to heat and evaporate boiler water, converting it into a steam-water mixture to provide the foundation for subsequent steam utilization (such as power output and production heat exchange). To maintain the purity of the steam, a steam-water separator is used to separate contaminants (solid impurities and water droplets, etc.) from the steam. In existing technologies, the steam-water separator is located inside the steam generator and is in direct contact with the steam. Therefore, the entire steam-water separator is at a high temperature. When the steam-water separator becomes clogged or needs replacement or maintenance, the steam generator must be shut down and cooled before the steam-water separator can be removed to ensure operational safety. After replacing the steam-water separator, the generator must be restarted to reheat the boiler water before normal steam generation can occur, reducing production efficiency.

[0007] As a preferred embodiment of the present invention, the rear side of the toothed ring meshes with a rack, and the rack is slidably connected to the connecting frame via a slide rail.

[0008] As a preferred embodiment of the present invention, a connecting assembly is fixedly installed inside the outer shell. The connecting assembly includes a steam outlet pipe, a steam inlet pipe, and a drain pipe. The steam outlet pipe is located directly above the steam-water separator, the steam inlet pipe is located on the upper left side of the steam-water separator, and the drain pipe is located at the bottom of the steam-water separator. The fixed pipes are all fixedly installed at the bottom ends of the steam outlet pipe, the steam inlet pipe, and the drain pipe.

[0009] As a preferred embodiment of the present invention, a flow divider assembly is fixedly installed at the left end of the steam inlet pipe. The flow divider assembly includes an electromagnetic three-way valve, which is fixedly installed on the left side of the steam inlet pipe. A one-way pipe is fixedly installed at the bottom end of the electromagnetic three-way valve.

[0010] As a preferred embodiment of the present invention, the drive assembly includes a support shaft, which is fixedly installed at the bottom of the housing. A sliding plate is slidably connected to the top of the support shaft. A motor is fixedly installed at the bottom of the front end of the sliding plate. A gear is fixedly sleeved at the output end of the motor. A maintenance door is hinged to the right end of the housing. A top block is fixedly installed at the left end of the maintenance door.

[0011] As a preferred embodiment of the present invention, the top end of the top block is in contact with the bottom surface of the sliding plate, and the left end of the top block is an inclined surface.

This invention uses a drive assembly to drive rack two to move the connecting rod as a whole, which in turn drives rack one to rotate the gear ring and the nut. Since the nut is engaged with the three connecting pipes of the steam-water separator, the nut can be unscrewed from the connecting pipes of the steam-water separator, separating the fixing pipe and the nut from the steam-water separator.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 8 As shown, the present invention provides a pollutant-resistant steam-water separator for an industrial boiler steam generator, including a housing 1, a support assembly 2 fixedly installed at the right end of the inner cavity of the housing 1, an installation assembly 3 provided at the right end of the support assembly 2, a rotating assembly 4 provided at both the upper and lower ends of the support assembly 2, and a drive assembly 7 fixedly installed in the inner cavity of the housing 1. The support assembly 2 includes a telescopic rod 21, which is fixedly installed at the upper and lower ends of the inner cavity of the outer shell 1. A spring 22 is sleeved on the surface of the telescopic rod 21, and a connecting frame 23 is fixedly installed in the middle of the telescopic rod 21. The mounting assembly 3 includes a fixed shaft 31, which is fixedly installed on the right end of the inner cavity of the housing 1. A rotating sleeve 32 is rotatably connected to the top end of the fixed shaft 31. A placement ring 33 is fixedly installed on the left end of the rotating sleeve 32. A steam-water separator 34 is placed in the inner cavity of the placement ring 33. The rotating assembly 4 includes a connecting rod 41, which is movably connected to the rear side of the connecting frame 23. A rack 42 is fixedly installed at both the top and bottom ends of the connecting rod 41. A fixing tube 43 is provided at both the top and bottom ends of the connecting frame 23. A nut 44 is rotatably connected to the bottom end of the fixing tube 43. A toothed ring 45 is fixedly installed on the side wall of the nut 44.

[0020] The drive assembly 7 drives the rack 2 81 to move the connecting rod 41 as a whole, which in turn drives the rack 1 42 to move and rotate the gear ring 45 and the screw nut 44. Since the screw nut 44 is engaged with the three connecting pipes of the steam-water separator 34, the screw nut 44 can be unscrewed from the connecting pipes of the steam-water separator 34, so that the fixing pipe 43 and the screw nut 44 are separated from the steam-water separator 34. At this time, rotating the rotating sleeve 32 can directly send out the placement ring 33 and the steam-water separator 34. The steam-water separator 34 can be hooked out from the outside using tools. When replacing, the personnel do not directly contact the steam-water separator 34, and the entire outer casing 1 does not need to be stopped, saving the cooling and reheating time required in the prior art and improving production efficiency.

[0021] The steam-water separator 34 is equipped with connecting pipes at the top, bottom and left side. Four positioning blocks are fixedly installed on the side wall of the steam-water separator 34. The top of the placement ring 33 has a groove, and the positioning blocks are placed in the groove.

[0022] By setting a positioning block to fix the position of the steam-water separator 34 and the placement ring 33, after the new steam-water separator 34 is placed, it can be ensured that after the steam-water separator 34 is screwed into the outer casing 1, the three connecting pipes of the steam-water separator 34 are respectively located directly below the three fixed pipes 43.

[0023] The front end of the connecting frame 23 contacts the positioning block, and the two ends of the spring 22 contact the connecting frame 23 and the outer shell 1 respectively.

[0024] The positioning block and the connecting frame 23 are used to position the steam-water separator 34 inside the housing 1, ensuring that the three connecting pipes of the steam-water separator 34 are aligned with the bottom end of the fixing pipe 43. When the screw nut 44 is turned, the screw nut 44 will rotate upward and leave the steam-water separator 34. The connecting frame 23 is responsible for moving the three screw nuts 44 upward synchronously. And through the elasticity of the spring 22, after replacement, the three screw nuts 44 can be pressed onto the steam-water separator 34 synchronously.

[0025] The rear side of the toothed ring 45 meshes with the rack 42, and the rack 42 is slidably connected to the connecting frame 23 via a slide rail.

[0026] The slide rail is set to position the rack 42 and the connecting frame 23, and to ensure that the rack 42 can smoothly mesh with the gear ring 45. When the rack 42 moves, it can drive the gear ring 45 and the nut 44 to rotate.

[0027] The outer casing 1 is equipped with a connecting component 5, which includes a steam outlet pipe 51, a steam inlet pipe 52, and a drain pipe 53. The steam outlet pipe 51 is located directly above the steam-water separator 34, the steam inlet pipe 52 is located on the upper left side of the steam-water separator 34, and the drain pipe 53 is located at the bottom of the steam-water separator 34. The fixing pipe 43 is fixedly installed at the bottom of the steam outlet pipe 51, the steam inlet pipe 52, and the drain pipe 53.

[0028] There are three fixed pipes 43. The three fixed pipes 43 are used to connect the steam outlet pipe 51, the steam inlet pipe 52 and the drain pipe 53 respectively to connect and fix the steam-water separator 34. The steam outlet pipe 51 is used to discharge the purified steam, the steam inlet pipe 52 is used to introduce the generated steam into the steam-water separator 34, and the drain pipe 53 is used to discharge the purified pollutants.

[0029] Among them, a flow divider assembly 6 is fixedly installed at the left end of the steam inlet pipe 52. The flow divider assembly 6 includes a solenoid three-way valve 61, which is fixedly installed on the left side of the steam inlet pipe 52. A one-way pipe 62 is fixedly installed at the bottom end of the solenoid three-way valve 61.

[0030] When replacing the steam-water separator 34, the solenoid three-way valve 61 closes the steam inlet pipe 52 and opens the one-way pipe 62. At this time, the generated steam is directly discharged into the drain pipe 53 through the one-way pipe 62. During normal operation, the one-way pipe 62 is closed, and the steam is completely sent into the steam inlet pipe 52 through the solenoid three-way valve 61.

[0031] The drive assembly 7 includes a support shaft 71, which is fixedly installed at the bottom of the housing 1. A sliding plate 72 is slidably connected to the top of the support shaft 71. A motor 73 is fixedly installed at the bottom of the front end of the sliding plate 72. A gear 74 is fixedly sleeved at the output end of the motor 73. A maintenance door 75 is hinged to the right end of the housing 1. A top block 76 is fixedly installed at the left end of the maintenance door 75.

[0032] Motor 73 drives gear 74 to rotate. When gear 74 meshes with gear 82, it drives switching assembly 8 to rotate. When gear 74 meshes with rack 81, it drives connecting rod 41 to move as a whole. The meshing state of gear 74 is related to the position of top block 76. Figure 7 As shown, gear 74 and gear 82 are in a meshing state. When the top block 76 is misaligned with the sliding plate 72, the sliding plate 72 moves down and meshes with rack 81.

[0033] The top of the top block 76 is in contact with the bottom surface of the sliding plate 72, and the left end of the top block 76 is an inclined surface.

[0034] By setting the left end of the top block 76 as an inclined surface, when rotating the maintenance door 75, the inclined surface first contacts the sliding plate 72, guiding the sliding plate 72 upward and resetting it.

[0035] The bottom of the steam-water separator 34 is provided with a switching component 8, which includes a rack 81 and a gear 82. The rack 81 is fixedly installed at the bottom of the connecting rod 41, and the gear 82 is rotatably connected in the inner cavity of the drain pipe 53. A scraper 83 is fixedly installed at the top of the gear 82, and the scraper 83 is in contact with the bottom of the inner wall of the steam-water separator 34.

[0036] During normal operation, gear 74 meshes with gear 82, and motor 73 intermittently drives gear 74 to rotate, which in turn drives gear 82 to rotate. When gear 82 rotates, it can drive scraper 83 to rotate in the inner cavity of steam-water separator 34, thereby cleaning the water storage area at the bottom of steam-water separator 34 and cleaning the attached impurities at the bottom of the inner cavity of steam-water separator 34, so as to extend the overall service life of steam-water separator 34.

[0037] The basic component 9 is fixedly installed in the inner cavity of the outer shell 1. The basic component 9 includes a water pump 91, which is fixedly installed at the bottom of the inner cavity of the outer shell 1. A heating tube 92 is fixedly installed at the output end of the water pump 91 and is fixedly installed on the side wall of the outer shell 1.

[0038] The water pump 91 is used to pump cold water into the heating tube 92, and the heating tube 92 heats and evaporates the cold water to generate steam.

[0039] Working principle and usage process of this invention: During normal operation, see Figure 7 Gear 1 74 meshes with gear 2 82. Motor 73 intermittently drives gear 1 74 to rotate, which in turn drives gear 2 82 to rotate. When gear 2 82 rotates, it can drive scraper 83 to rotate in the inner cavity of steam-water separator 34, thereby enabling scraper 83 to scrape and clean the water storage area at the bottom of steam-water separator 34. Electromagnetic three-way valve 61 controls the closure of one-way pipe 62 and the opening of steam inlet pipe 52. The water pump 91 is used to pump cold water into the heating tube 92. The heating tube 92 heats and evaporates the cold water to generate steam. The generated steam enters the steam-water separator 34 through the steam inlet pipe 52. The steam is separated by the steam-water separator 34. The separated water droplets and impurities are discharged downward through the drain pipe 53, while the steam enters the steam outlet pipe 51 from the pipe inside the steam-water separator 34 and is sent out. This is the prior art and will not be described in detail here. When the steam-water separator 34 needs to be replaced, the solenoid three-way valve 61 opens the one-way pipe 62 and closes the steam inlet pipe 52, opens the maintenance door 75, and the maintenance door 75 drives the top block 76 away from the bottom of the sliding plate 72. At this time, the sliding plate 72 falls under the action of gravity, causing the gear 1 74 to separate from the scraper 83 and mesh with the rack 2 81. Then the motor 73 drives the rack 2 81 to move, driving the connecting rod 41 and the rack 1 42 to move as a whole. Through meshing with the gear ring 45, the screw nut 44 is rotated, thereby unscrewing the screw nut 44 from the steam-water separator 34. Finally, rotating the rotating sleeve 32 sends the placement ring 33 and the steam-water separator 34 out of the device, and the steam-water separator 34 is taken out with a lifting tool and replaced with a new one and placed on the placement ring 33; finally, it is sent into the outer shell 1, the toothed ring 45 rotates in the opposite direction, and after tightening the nut 44, the electromagnetic three-way valve 61 opens the steam inlet pipe 52 and closes the one-way pipe 62.
