Description

Technical Field

[0001] This invention relates to the field of cement pole production technology, and in particular to a steam curing device for high-strength, corrosion-resistant cement poles with waste heat recovery. Background Technology

[0002] In the production process of cement utility poles, in order to ensure the quality of the poles and improve production efficiency, steam is used to steam-cur the poles. Steam can accelerate the cement hydration reaction, allowing the concrete to reach the demolding strength within a few hours. It can also reduce problems such as cracking and peeling caused by excessive moisture evaporation, ensuring that the internal structure of the utility poles is dense and the surface is free of defects.

[0003] Existing steam curing equipment typically sprays steam upwards from the bottom of the device. As a result, the power poles are difficult to heat evenly at the start of steam curing, with a temperature difference of 2 to 3 degrees Celsius between the top and bottom. This can cause internal cracking of the power poles. At the same time, steam condenses into water inside the steam curing device, and the water drips onto the power poles, causing corrosion. Since the power poles are stationary, the continuous dripping water can also easily form dents on the poles, further reducing their quality. In addition, traditional steam curing equipment lacks heat recovery capabilities, allowing steam heat to escape into the air, resulting in energy waste. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a steam curing device for high-strength corrosion-resistant cement power poles with waste heat recovery.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A steam curing device for high-strength, corrosion-resistant cement utility poles with waste heat recovery includes: A fixed base is provided, on which a steam oven shell is fixedly installed. A compressed steam box and a heating water tank are also fixedly installed on the fixed base. A steam return pipe and a water flow pipe communicating with the interior of the steam oven shell are fixedly installed on the heating water tank. The heating water tank and the compressed steam box are fixedly connected by a steam conduit. The steam curing structure includes two mounting plates. Two fixing plates are symmetrically fixedly mounted on the fixing base. A fixing pipe is fixedly mounted on the mounting plate. The fixing pipe penetrates the inner wall of the steam curing unit's outer shell and is fixedly connected to the compressed steam box. The mounting plate is fixedly connected to the corresponding fixing plate. A fixing shaft is rotatably connected between the fixing plates. A placement roller is fixedly sleeved on the fixing shaft. A steam guide plate communicating with the fixing pipe is rotatably mounted on the side wall of the mounting plate. A steam plate is fixedly connected between the two steam guide plates through a connecting pipe. Multiple steam nozzles are fixedly mounted on the steam plate. A power structure is fixedly mounted on the fixing plate.

[0006] Preferably, a scraper structure is fixedly installed inside the steam generator shell. The scraper structure includes a fixed shell, which is fixedly connected to the inner wall of the steam generator shell via a connecting block. Two connecting shafts are rotatably connected between the fixed shells. A scraper is fixedly installed on the connecting shaft. The connecting shaft passes through the inner wall of the fixed shell and is fixedly connected to a fixed worm gear. A fixed worm gear that meshes with the fixed worm gear is rotatably installed between the inner walls of the fixed shells. The fixed worm gear is installed between the fixed worm gears. A rotating shaft is rotatably connected to the fixed worm gear. The rotating shaft passes through the inner wall of the fixed shell and extends to the inner side of the corresponding steam return pipe. A fluid impeller is fixedly installed on the rotating shaft.

[0007] Preferably, the wiper blade is made of hardened silicone, and an auxiliary wiper blade perpendicular to it is fixedly installed on the side wall of the wiper blade. The side wall of the auxiliary wiper blade is chamfered. The wiper blades on both sides are centrally symmetrical about the corresponding connecting shaft, and the wiper blades on both sides are installed alternately.

[0008] Preferably, the power structure includes a motor fixedly mounted on the side wall of the fixed plate, a corresponding fixed shaft passing through the fixed plate and fixedly connected to the output end of the motor, the fixed shafts being connected by a synchronous belt drive assembly, the fixed plate having a fixed cavity inside, the fixed shaft passing through the inner wall of the fixed cavity and extending to the inner side of the fixed cavity, and the synchronous belt drive assembly being mounted on the inner side of the fixed cavity, a fixed toothed ring being fixedly mounted on the inner wall of the steam guide plate, and a fixed gear meshing with the fixed toothed ring being fixedly sleeved on the fixed shaft.

[0009] Preferably, a protective shell is fixedly snapped onto the side wall of the fixing plate, and the protective shell encloses the motor inside. The fixing plate, fixing gear ring, fixing gear and protective shell are all made of corrosion-resistant plastic.

[0010] Preferably, a steam blower is fixedly installed on the steam return pipe, filter elements are fixedly installed in both the steam return pipe and the water flow pipe, and a one-way valve is fixedly installed in the steam duct.

[0011] Preferably, a sealing cover is slidably installed on the side wall of the steam oven shell, and a sealing gasket is fixedly installed at the connection between the sealing cover and the steam oven shell.

[0012] Preferably, the inner wall of the steamer shell has an arc-shaped water guide groove, and the surface of the fixing seat is inclined downwards towards the water flow pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. Steam is sprayed out of the outside of the utility pole in a ring shape to avoid uneven heating of the pole, which could lead to a large temperature difference between the top and bottom of the pole. This prevents the pole from cracking during the steam curing process. At the same time, the steam curing structure can rotate in a circular motion, and the utility pole can rotate in the opposite direction of the rotation of the steam curing structure, which further ensures more thorough contact between the utility pole and the steam and more uniform heating. 2. Use a scraper to scrape the condensate on the inner wall of the steam oven to both sides to prevent excessive condensate from dripping onto the utility pole. The staggered scrapers and auxiliary scrapers work together to block and restrict the water dripping from the steam oven shell as the scrapers rotate, and also prevent the water on the scrapers from sliding onto the utility pole. 3. The rotation of the utility pole causes the very small amount of water droplets that fall on the pole to rotate with it and flow down, thus preventing water from remaining on the pole and causing corrosion, and also preventing water from dripping in one place and causing dents on the pole. 4. It can recover steam and condensed water, and send the high-temperature water and steam back to the heating water tank for recycling. The high temperature of the steam and water itself reduces the energy required for heating, thus achieving the effect of recovering waste heat and saving energy. Attached Figure Description

[0016] See Figures 1-8 A steam curing device for high-strength, corrosion-resistant cement utility poles with waste heat recovery, comprising: A fixed base 1 is provided, on which a steam oven shell 2 is fixedly installed. A compressed steam box 4 and a heating water tank 5 are also fixedly installed on the fixed base 1. Both the compressed steam box 4 and the heating water tank 5 are existing equipment. The compressed steam box 4 is equipped with a compressor, which can pressurize the steam to facilitate its ejection. The heating water tank 5 heats the water by electric heating, causing it to boil and evaporate into steam. A steam return pipe 6 and a water flow pipe, which are connected to the inside of the steam oven shell 2, are fixedly installed on the heating water tank 5. The heating water tank 5 and the compressed steam box 4 are fixedly connected by a steam conduit. The steam curing structure 8 includes two mounting plates 81. Two fixing plates 10 are symmetrically fixedly mounted on the fixing base 1. Fixing pipes 13 are fixedly mounted on the mounting plates 81, penetrating the inner wall of the steam curing unit 2 and communicating with the compressed steam box 4. The mounting plates 81 are fixedly connected to the corresponding fixing plates 10. A fixing shaft 12 is rotatably connected between the fixing plates 10. A placement roller 11 is fixedly sleeved on the fixing shaft 12. A steam guide plate 82 communicating with the fixing pipe 13 is rotatably mounted on the side wall of the mounting plate 81. The steam guide plate 82 is generally annular, and a steam groove is opened inside the steam guide plate 82. At the connection surface between plate 82 and mounting plate 81, the fixing pipe 13 can penetrate the mounting plate 18 and extend into the steam tank to deliver steam. Since the fixing pipe 13 is not connected to the steam guide plate 82, the fixing pipe 13 will not affect the rotation of the steam guide plate 82. The two steam guide plates 82 are fixedly connected by a connecting pipe 83. Multiple steam nozzles 85 are fixedly installed on the steam plate 84. The inside of the steam plate 84 is fixedly installed with pipes that communicate with the steam nozzles 85 and the connecting pipe 83, which are used to deliver steam to the steam nozzles 85 so that the steam is ejected. A power structure is fixedly installed on the fixing plate 10. After the utility pole is placed on the placement roller 11, steam enters the compressed steam box 4 through the steam pipe. After being pressurized, it enters the steam guide plate 82 from the fixed pipe 13, and then is sprayed out from the steam nozzle 85 through the connecting pipe 83 and the steam plate 84 to steam-cur the utility pole. The steam nozzle 85 is installed around the utility pole, so the utility pole can be heated more evenly, avoiding cracking of the utility pole due to uneven heating. At the same time, under the action of the power structure, the utility pole and the steam nozzle 85 rotate in opposite directions, further making the steam and the utility pole come into even and sufficient contact. A scraper structure 9 is fixedly installed inside the steam oven shell 2. The scraper structure 9 includes a fixed shell 91, which is fixedly connected to the inner wall of the steam oven shell 2 via a connecting block 96. Two connecting shafts 92 are rotatably connected between the fixed shells 91. A scraper 93 is fixedly installed on the connecting shafts 92. The connecting shafts 92 pass through the inner wall of the fixed shells 91 and are fixedly connected to a fixed worm gear 94. A fixed worm 95 is rotatably installed between the inner walls of the fixed shells 91 and meshes with the fixed worm gear 94. The fixed worm gear 95 is installed between the fixed worm gears 94. Fixed worm gears are installed on both sides of the fixed worm 95. The opposite rotation directions of 94 cause the connecting shaft 92 and the scraper 93 to rotate in opposite directions as well. A rotating shaft 97 is rotatably connected to the fixed worm gear 95. The rotating shaft 97 passes through the inner wall of the fixed shell 91 and extends to the inner side of the corresponding steam return pipe 6. A fluid impeller 98 is fixedly installed on the rotating shaft 97. One side wall of the blade of the fluid impeller 98 is straight, and the other side wall is arc-shaped. Therefore, when steam passes through, there will be a difference in the flow velocity of the steam on both sides of the blade. The different flow velocities cause a difference in pressure on both sides of the blade. The pressure drives the blade to rotate, thereby causing the fluid impeller 98 to rotate. When steam flows back, the fluid impeller 98 rotates, which in turn drives the rotating shaft 97, which is fixedly connected to the fluid impeller 98, to rotate. When the rotating shaft 97 rotates, it drives the fixed worm 95 to rotate as well, causing the fixed worm wheel 94, which meshes with the fixed worm 95, to rotate. The fixed worm wheels 94 on both sides rotate in opposite directions. The rotation of the fixed worm wheel 94 causes the connecting shaft 92 to rotate as well, which drives the scraper 93, which is fixedly installed on the connecting shaft 92, to rotate. The scraper 93 on both sides rotate in opposite directions, scraping the condensate to both sides to prevent the condensate from accumulating and dripping onto the utility pole, causing corrosion to the utility pole. The wiper blade 93 is made of hardened silicone, and an auxiliary wiper blade perpendicular to it is fixedly installed on the side wall of the wiper blade 93. The side wall of the auxiliary wiper blade has a chamfer to assist the wiper blade 93 in wiping water, and at the same time, it can also limit and restrain the water droplets wiped out. The wiper blades 93 on both sides are centrally symmetrically distributed about the corresponding connecting shaft 92, and the wiper blades 93 on both sides are installed alternately to avoid collisions during the rotation of the wiper blades 93. At the same time, when one wiper blade 93 is wiping water, there is always another wiper blade 93 blocking it below. Together with the auxiliary wiper blade, it can catch any water that may drip down and prevent it from dripping onto the utility pole. Finally, the very small amount of water droplets that drip onto the utility pole will slide off with the rotation of the utility pole and will not remain on the utility pole to cause corrosion. At the same time, the rotation of the utility pole also prevents water droplets from dripping in one position on the utility pole and causing dents on the utility pole. The power structure includes a motor 810 fixedly installed on the side wall of the fixed plate 10, a corresponding fixed shaft 12 passing through the fixed plate 10 and fixedly connected to the output end of the motor 810, the fixed shafts 12 being connected by a synchronous belt drive assembly 87, a fixed cavity 86 being opened inside the fixed plate 10, the fixed shaft 12 passing through the inner wall of the fixed cavity 86 and extending to the inner side of the fixed cavity 86, and the synchronous belt drive assembly 87 being installed inside the fixed cavity 86, a fixed toothed ring 88 being fixedly installed on the inner wall of the steam guide plate 82, and a fixed gear 89 being fixedly sleeved on the fixed shaft 12 and meshing with the fixed toothed ring 88; When the motor 810 is started, the output end of the motor 810 drives the corresponding fixed shaft 12 to rotate. Under the action of the synchronous belt drive assembly 87, the two fixed shafts 12 rotate synchronously. At the same time, when the fixed shaft 12 rotates, the fixed gear 89 fixedly sleeved on the fixed shaft 12 rotates accordingly, causing the fixed gear ring 88 meshing with the fixed gear 89 to rotate together, and the direction of rotation is opposite to that of the fixed gear 89. The rotation of the fixed gear ring 88 drives the steam guide plate 82 to rotate. The side wall of the fixing plate 10 is fixedly snapped with a protective shell. The snapping is achieved through a structure such as a snap-fit ​​block, which does not require metal bolts. The snap-fit ​​block can be made of non-metallic material, which can reduce the corrosion of steam and make it easier to open the protective shell, which is beneficial for the maintenance of the motor 810. The protective shell wraps the motor 810 inside. The fixing plate 10, the fixing gear ring 88, the fixing gear 89 and the protective shell are all made of corrosion-resistant plastic. Corrosion-resistant plastic is non-metallic and is not easily corroded by steam, which can extend the service life of the device. A steam blower 7 is fixedly installed on the steam return pipe 6. After the steam blower 7 is started, steam is drawn into the steam return pipe 6 to accelerate the flow of steam. Filter elements are fixedly installed in both the steam return pipe 6 and the water flow pipe. The filter elements have a filtering effect to prevent dust and other particles from entering the heating water tank. A one-way valve is fixedly installed in the steam pipe to prevent steam backflow. A sealing cover 3 is slidably installed on the side wall of the steam curing unit 2, and a sealing gasket is fixedly installed at the connection between the sealing cover 3 and the steam curing unit 2. When the power pole is steam cured, the sealing cover 3 is closed to seal the steam curing unit 2 and prevent steam leakage. The inner wall of the steam oven shell 2 has an arc-shaped water guide groove. The guide groove is used to guide the flow of condensate, so that after the condensate is scraped to both sides by the scraper 93, it can flow down quickly. The surface of the fixed base 1 is inclined downward towards the water flow pipe, so the condensate can flow to the water flow pipe and return to the heating water tank 5. Together with the steam recovered by the steam return pipe 6, waste heat is recovered. The higher temperature water and steam also reduce the energy required for reheating, which achieves the effect of energy saving.

[0017] In this invention, when the device is in use, first open the sealing cover 3, place the utility pole on the placement roller 11, then close the sealing cover 3, start the heating water tank 5 to heat the water, causing it to boil and evaporate into steam. The steam enters the compressed steam tank 4 through the steam pipe, and after being pressurized, it enters the steam guide plate 82 from the fixed pipe 13, and then is sprayed out from the steam nozzle 85 through the connecting pipe 83 and the steam plate 84 to steam-cur the utility pole. The steam nozzle 85 is installed around the utility pole, so the utility pole can be heated more evenly. The steam blower draws the steam into the steam return pipe 6 to accelerate the flow of steam. The steam returns to the heating water tank 5 through the steam return pipe 6. Moreover, during the steam curing process, the steam will condense into water droplets on the inner wall of the steamer shell 2. The water droplets will return to the heating water tank 5 from the water flow pipe. The residual heat of the steam and water droplets heats the heating water tank 5, recovering residual heat and reducing the energy consumption of the device. Simultaneously, the motor 810 is started, and the output end of the motor 810 drives the corresponding fixed shaft 12 to rotate. Under the action of the synchronous belt drive assembly 87, the two fixed shafts 12 rotate synchronously. The rotation of the fixed shaft 12 will cause the placement roller 11, which is fixedly sleeved on the outside of the fixed shaft 12, to rotate, which will drive the electric pole placed on the placement roller 11 to rotate together. At the same time, when the fixed shaft 12 rotates, the fixed gear 89, which is fixedly sleeved on the fixed shaft 12, will rotate accordingly, causing the fixed gear ring 88, which meshes with the fixed gear 89, to rotate together, and the rotation direction is opposite to that of the fixed gear 89. The rotation of the fixed gear ring 88 will drive the steam guide plate 82 to rotate, which will cause the connecting pipe 83, steam plate 84 and steam nozzle 85 to rotate accordingly, and the rotation direction of the steam nozzle 85 is opposite to that of the electric pole, which will further make the steam and the electric pole come into uniform and sufficient contact, and make the electric pole more evenly heated. When steam recirculates, it causes the fluid impeller 98 to rotate, which in turn drives the rotating shaft 97, which is fixedly connected to the fluid impeller 98, to rotate. The rotation of the rotating shaft 97 drives the fixed worm 95 to rotate as well, causing the fixed worm wheel 94, which meshes with the fixed worm 95, to rotate. The two fixed worm wheels 94 rotate in opposite directions. The rotation of the fixed worm wheels 94 causes the connecting shaft 92 to rotate, which in turn drives the scraper blades 93, which are fixedly mounted on the connecting shaft 92, to rotate. The two scraper blades 93 rotate in opposite directions, scraping the condensate to the sides to prevent condensate accumulation and dripping. On utility poles, the alternating installation of squeegees 93 prevents corrosion. While one squeegee 93 is squeegeing, another squeegee 93 is always positioned below it, working in conjunction with the auxiliary squeegee to catch any dripping water and prevent it from falling onto the pole. Even the very small amount of water that does drip onto the pole will slide off as the pole rotates, preventing it from remaining and corroding. Furthermore, the rotation of the pole prevents water droplets from remaining in one spot and causing dents, thus improving the overall quality of the utility pole.
