Description

Technical Field

[0001] This invention relates to the field of cement pole production technology, and more particularly to a steam curing device for cement pole production. Background Technology

[0002] Cement utility poles are widely used infrastructure components in power, telecommunications, and municipal engineering projects. The steam curing process during their production is a key step that determines the strength and quality of the product. During operation, the cast-in-place pole mold is hoisted into the steam curing equipment. High-temperature steam is introduced into the equipment through a steam supply system, causing the cement to undergo a rapid hydration reaction in a humid and hot environment, thereby shortening the curing cycle and improving production efficiency.

[0003] Currently, in the steam curing process of cement utility poles, the cement pole mold is placed inside the steam curing chamber, the top of which is sealed, and high-temperature steam is introduced into the chamber to steam cure the cement pole. However, in actual use, due to the high temperature inside the steam curing chamber, the steam easily condenses into water droplets when it comes into contact with the top cover and chamber walls. If this condensate drips onto the surface of the cement utility pole that has not yet fully cured, it will cause a local water-cement ratio imbalance, resulting in quality problems such as pitting, cracks, and even reduced strength on the product surface. Therefore, it is necessary to invent a steam curing equipment for cement utility pole production to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a steam curing device for the production of cement utility poles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A steam curing device for producing cement utility poles includes a platform, a steam curing chamber inside the platform, baffles on the front and back inner walls of the steam curing chamber, a control chamber and a drainage chamber on the left and right sides of the platform, a sealing mechanism on the top of the platform, a steam supply mechanism extending from the inside of the steam curing chamber into the control chamber, and a drainage mechanism extending from the inside of the steam curing chamber into the drainage chamber. The sealing mechanism includes a top cover, which is slidably installed on the top of the platform. An arc-shaped water groove is formed on the inner wall of the top cover. Two mounting brackets are fixedly installed at the bottom of the platform. Rollers are rotatably installed inside the mounting brackets. A first air pipe is fixedly installed inside the top cover near the front side. A second air pipe is fixedly installed inside the top cover near the back side. An arc-shaped air pipe is fixedly installed between the first and second air pipes. A first water pipe is fixedly installed at the left end of the first and second air pipes. A three-way solenoid valve is installed on the first water pipe. A first drain pump is fixedly installed on the top of the top cover. A drain pipe is provided outside the drain pump. A second water pipe is fixedly installed on the left side of the top cover. Water collection grooves are formed inside the top cover near both the front and back sides.

[0006] Preferably, an exhaust pipe is fixedly installed on the right side of the second air pipe, and an anti-backflow bend is fixedly installed between the first air pipe and the right side of the top cover.

[0007] Preferably, the top cover has an arc-shaped groove inside, and the arc-shaped air pipe is located inside the arc-shaped groove.

[0008] Preferably, the steam supply mechanism includes multiple steam pipes, which are rotatably installed inside the steam curing chamber. Multiple nozzles are provided on each steam pipe. Two central pipes are fixedly installed inside the control chamber. A steam inlet pipe is provided at the top of each central pipe, and multiple rotating joints are provided on the right side of each central pipe. A motor is fixedly installed inside the control chamber. A first gear is fixedly installed at the output end of the motor. A second gear is fixedly installed on the outer left side of the steam pipe near the back. The first gear meshes with the second gear. Sprockets are fixedly installed on the outer side of the steam pipe near the front and on the outer side of the motor's output end. A chain is installed between two adjacent sprockets for transmission.

[0009] Preferably, a through hole is provided between the control chamber and the steam curing chamber, and the left side of the plurality of steam pipes is rotatably installed inside the through hole.

[0010] Preferably, the drainage mechanism includes a fixed frame, which is fixedly installed inside the control chamber. A sliding frame is slidably installed inside the fixed frame. A sealing plug is fixedly installed on the left side of the sliding frame, and an electric telescopic rod is fixedly installed on the right side of the fixed frame. A water pump and a second drainage pump are provided inside the drainage chamber, and the water pump is fixedly installed on the second drainage pump. A drainage pipe is fixedly installed on the top of the second drainage pump. Multiple drainage grooves are provided on the bottom wall of the steam curing chamber.

[0011] Preferably, the drainage channel is tilted to the right, and the sealing plug is inserted inside the drainage channel, and the bottom wall of the drainage chamber is tilted to the front.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. The residual heat steam rising in the steam curing chamber is introduced into the first air pipe, the arc-shaped air pipe, and the second air pipe through the anti-backflow bend. The residual heat of the steam is used to evenly heat the top cover, increasing the dew point temperature of the top cover and fundamentally reducing steam condensation caused by temperature difference. The inner wall of the top cover is equipped with an arc-shaped water groove, which can guide a small amount of condensate to the water collection grooves on both sides. Through the cooperation of the first drain pump, the three-way solenoid valve, and the second water pipe, the condensate in the water collection groove is automatically pumped out, preventing condensate from dripping onto the surface of the cement pole and ensuring the appearance and strength of the product. After steam curing, the three-way solenoid valve can be switched to use the first drain pump to pump out the residual condensate in the first air pipe, the second air pipe, and the arc-shaped air pipe, preventing water accumulation in the pipes from corroding or affecting the next use. 2. By driving the first gear and the second gear to mesh with the motor, and through the transmission of the sprocket and the chain, the steam pipes on the front and rear sides rotate synchronously in opposite directions, thereby adjusting the steam spray angle of the nozzles. This causes the steam to drive the air in the chamber to form a circulating flow, breaking the static "supersaturated layer" at the top and reducing the adhesion of condensate on the inner wall of the top cover. After the steam spray angle is adjusted, a high-speed hot air flow layer can be formed below the inner wall of the top cover, which not only heats the top plate to reduce the temperature difference, but also blows away the water droplets that are about to condense, improving the uniformity and stability of the steam curing environment. 3. Multiple drainage channels with a rightward inclination are provided at the bottom of the steam curing chamber, which can naturally guide the condensate generated in the chamber to the right-side drain outlet to avoid water accumulation. The opening and closing of the sliding frame and sealing plug are controlled by an electric telescopic rod to realize the automatic discharge of the drainage channels. The bottom of the drainage chamber is inclined forward, and together with the second drainage pump and water pipe, the collected condensate can be quickly discharged to the outside of the equipment to prevent condensate from accumulating and affecting the steam curing quality or causing equipment corrosion.

[0015] See Figures 1-12 A steam curing device for producing cement utility poles includes a platform 1, a steam curing chamber 2 inside the platform 1, baffles 3 on the front and back inner walls of the steam curing chamber 2, a control chamber 4 and a drainage chamber 5 on the left and right sides of the platform 1 respectively, a sealing mechanism 6 on the top of the platform 1, a steam supply mechanism 7 extending from the inside of the steam curing chamber 2 to the control chamber 4, and a drainage mechanism 8 extending from the inside of the steam curing chamber 2 to the drainage chamber 5.

[0016] In the existing technology, during the steam curing process of cement poles, the mold containing the cement pole is usually placed in the steam curing chamber 2, the top is sealed, and high-temperature steam is introduced for curing. However, in actual operation, due to the high temperature inside the steam curing chamber 2, the steam easily condenses into water droplets when it comes into contact with the top cover 61 and the chamber wall. These condensed water droplets fall onto the surface of the cement pole that has not yet fully cured, which will cause a local imbalance in the water-cement ratio, resulting in surface pitting, cracks, and even quality problems such as reduced strength.

[0017] In this invention, during use, the sealing mechanism 6 circulates the steam rising in the curing chamber 2 and guides it into the interior of the top cover 61, heating the top cover 61 and increasing its dew point temperature. This reduces steam condensation on the top cover 61 and collects and discharges any small amount of condensate, preventing it from dripping onto the cement pole mold. The steam supply mechanism 7 adjusts the steam injection angle, allowing the steam to circulate and disrupt the supersaturated layer of steam that accumulates statically at the top. This prevents the humid air from continuously adhering to the top surface and condensing. Furthermore, a high-speed hot airflow layer forms below the inner wall of the kiln top, heating the top surface, reducing temperature differences, and dispersing any condensing water droplets. Finally, the drainage mechanism 8 drains excess condensate from the curing chamber 2 during use, preventing its accumulation and potential impact on the cement poles inside.

[0018] See Figures 3-6 The sealing mechanism 6 includes a top cover 61, which is slidably mounted on the top of the platform 1. The inner wall of the top cover 61 has an arc-shaped structure, and an arc-shaped water groove 62 is formed on the inner wall of the top cover 61. Two mounting brackets 63 are fixedly mounted on the bottom of the platform 1. Rollers 64 are rotatably mounted inside the mounting brackets 63. A sliding groove is formed on the top of the platform 1, and the rollers 64 are rotatably mounted inside the sliding groove. A first air pipe 65 is fixedly mounted inside the top cover 61 near the front side, and a second air pipe 66 is fixedly mounted inside the top cover 61 near the back side. An arc-shaped air pipe 67 is fixedly mounted between the first air pipe 65 and the second air pipe 66. Multiple arc-shaped air pipes 67 are provided and are fixedly mounted in a linear array. Between the first air pipe 65 and the second air pipe 66, a first water pipe 68 is fixedly installed on the left side of the first air pipe 65 and the second air pipe 66. A three-way solenoid valve 69 is installed on the first water pipe 68. A first drain pump 610 is fixedly installed on the top of the top cover 61. The end of the first water pipe 68 away from the first air pipe 65 and the second air pipe 66 is fixedly installed on the drain pump. A drain pipe 611 is installed outside the drain pump. A second water pipe 612 is fixedly installed on the left side of the top cover 61. The end of the second water pipe 612 away from the top cover 61 is fixedly installed on the three-way solenoid valve 69. Water collection tanks 615 are opened inside the top cover 61 near the front and back. The second water pipe 612 is connected to the two water collection tanks 615.

[0019] See Figure 5 and Figure 6 An anti-backflow bend 614 is fixedly installed between the first air pipe 65 and the right side of the top cover 61, which is used to send the steam inside the steam curing chamber 2 into the first air pipe 65.

[0020] The top cover 61 has an arc-shaped groove inside, and the arc-shaped air pipe 67 is located inside the arc-shaped groove.

[0021] In this invention, when steam enters the steam curing chamber 2, due to its low density, the steam rises inside the chamber. The steam rises to the top cover 61, and excess steam is sent to the first air pipe 65 via the anti-backflow bend 614. The steam is then sent to the second air pipe 66 via the arc-shaped air pipe 67 connected to the first air pipe 65. The steam inside the first air pipe 65, the second air pipe 66, and the arc-shaped air pipe 67 heats the top cover 61, thereby increasing its temperature and dew point temperature. This prevents excessive condensation due to the low temperature of the top cover 61. The excess steam is discharged through the exhaust pipe 613, and simultaneously, a small amount of condensate on the top cover 61 slides off through the arc-shaped water groove 62 on the inner wall of the top cover 61, allowing it to drain into the water accumulation areas on both sides. After prolonged use, the first drain pump 610 is turned on and the second water pipe 612 is opened by the three-way solenoid valve 69, causing the first drain valve to extract the condensate from the water tank 615 and discharge it through the drain pipe 611. During use, the condensate is drained away by connecting the hose to the drain pipe 611. After use, due to the drop in temperature, condensate easily appears in the first air pipe 65, the second air pipe 66, and the arc-shaped air pipe 67. Due to its arc-shaped structure, the condensate in the arc-shaped air pipe 67 flows to both sides and enters the first air pipe 65 and the second air pipe 66. At this time, the three-way solenoid valve 69 is switched so that the first drain pump 610 extracts the condensate from the first air pipe 65 and the second air pipe 66 through the first water pipe 68 and discharges it through the drain pipe 611.

[0022] See Figures 7-9 The steam supply mechanism 7 includes multiple steam pipes 71, which are rotatably installed inside the steam curing chamber 2. The front and back inner walls of the steam curing chamber 2 are provided with mounting grooves, and the multiple steam pipes 71 are rotatably installed inside the mounting grooves. Multiple nozzles 72 are provided on the steam pipes 71. Two central pipes 73 are fixedly installed inside the control chamber 4. A steam inlet pipe 74 is provided at the top of the central pipe 73. Multiple rotating joints 75 are provided on the right side of the central pipe 73. The left end of the steam pipe 71 is rotatably installed on the rotating joint 75. A motor 76 is fixedly installed inside the control chamber 4. A first gear 77 is fixedly installed at the output end of the motor 76. A second gear 78 is fixedly installed on the left side of the steam pipe 71 near the back side. The first gear 77 and the second gear 78 mesh with each other. Sprockets 79 are fixedly installed on the outside of the steam pipe 71 near the front side and on the outside of the output end of the motor 76. A chain 710 is installed between two adjacent sprockets 79.

[0023] See Figure 7 A through hole is provided between the control chamber 4 and the steam curing chamber 2, and multiple steam pipes 71 are rotatably installed inside the through hole on the left side.

[0024] In this invention, the steam inlet pipe 74 is connected to a steam generating device, which sends steam into a central pipe 73 through the steam inlet pipe 74. The steam is then sent into a steam pipe 71 through a rotating joint 75 on the central pipe 73. High-temperature steam is then sent into the interior of the steam curing chamber 2 through a nozzle 72 on the steam pipe 71. A motor 76 drives a first gear 77 to rotate, which in turn drives the steam pipe 71 near the back side to rotate through a meshing second gear 78. Simultaneously, the motor 76 drives a sprocket 79 to rotate, which in turn drives the steam pipe 71 near the front side to rotate through a chain 710. This causes the steam pipes 71 on both sides to rotate synchronously in opposite directions, adjusting the steam spray angle of the nozzle 72 on the steam pipe 71. This allows the steam to drive the surrounding air to form a circulating flow, breaking the "supersaturated layer" where steam accumulates statically at the top. This prevents the hot and humid air from continuously adhering to the surface of the top plate and condensing. Furthermore, a high-speed hot airflow layer is formed below the inner wall of the kiln top, which both heats the top plate to reduce the temperature difference and disperses the water droplets that are about to condense.

[0025] See Figures 10-12 The drainage mechanism 8 includes a fixed frame 81, which is fixedly installed inside the control chamber 4. A sliding frame 82 is slidably installed inside the fixed frame 81. A sealing plug 83 is fixedly installed on the left side of the sliding frame 82. An electric telescopic rod 84 is fixedly installed on the right side of the fixed frame 81. Multiple electric telescopic rods 84 are provided, and waterproof electric telescopic rods 84 are used. The telescopic end of the electric telescopic rod 84 passes through the fixed frame 81 and is fixedly installed on the right side of the sliding frame 82. The drainage chamber 5 is provided with a water pump 85 and a second drainage pump 86. The water pump 85 is fixedly installed on the second drainage pump 86. A drainage pipe 611 is fixedly installed on the top of the second drainage pump 86. Multiple drainage grooves 88 are opened in the bottom wall of the steam curing chamber 2.

[0026] See Figure 10 and Figure 12 The drainage trough 88 is tilted to the right, and the sealing plug 83 is inserted into the inside of the drainage trough 88. The bottom wall of the drainage chamber 5 is tilted to the front, and the water pumping pipe 85 is connected to its bottom for pumping water out from the bottom of the drainage chamber 5.

[0027] In this invention, the condensate generated inside the steam curing chamber 2 is collected and flows to the right through the drainage trough 88. The sliding frame 82 is driven to slide to the right on the fixed frame 81 by the electric telescopic rod 84, causing the sliding frame 82 to open the sealing plug 83. At this time, the condensate inside the drainage trough 88 flows into the drainage chamber 5. Then the sealing plug 83 is closed, and the second drainage pump 86 is started, causing the water pumping pipe 85 on the second drainage pump 86 to draw out the condensate from the drainage chamber 5 and discharge it through the discharge pipe 87. This discharges the excess condensate generated inside the steam curing chamber 2, preventing the condensate from accumulating inside the steam curing chamber 2 and affecting the cement poles inside.

[0028] In this invention, the drain pipe 611 and the discharge pipe 87 are connected by a hose to discharge the condensate generated subsequently. The steam inlet pipe 74 is connected to the steam generating equipment. The top cover 61 is connected to the traction equipment so that the traction equipment drives the top cover 61 to slide through the roller 64. First, the top cover 61 is opened by the traction device, and then the cement pole mold is placed into the steam curing chamber 2. Then, the top cover 61 is slid closed by the traction device. The steam generating device sends steam into the central pipe 73 through the steam inlet pipe 74. The steam is sent into the steam pipe 71 through the rotating joint 75 on the central pipe 73. The steam is sprayed into the interior of the steam curing chamber 2 through the nozzle 72 on the steam pipe 71. The motor 76 is started, driving the first gear 77 to rotate. The second gear 78 meshes with the first gear and drives the steam pipe 71 on the back side to rotate. Steam rises inside the steam curing chamber 2 and is sent into the first air pipe 65, the arc-shaped air pipe 67, and the second air pipe 66 through the anti-backflow bend 614. The first air pipe 65, the arc-shaped air pipe 67, and the second air pipe 66 heat the top cover 61. Excess steam is discharged through the exhaust pipe 613. A small amount of condensate is sent into the water collection tank 615 through the arc-shaped water tank 62 structure on the top cover 61. After long-term use, the first drain pump 610 is turned on and the second water pipe 612 is opened by the three-way solenoid valve 69, so that the first drain valve draws out the condensate in the water collection tank 615 and discharges it through the drain pipe 611. During use, the condensate is drained away by connecting the hose to the drain pipe 611. After steam curing is completed, the top cover 61 is slid open by the traction device to lift out the internal cement pole mold. Then, the condensate generated inside the steam curing chamber 2 is collected and flows to the right through the drainage trough 88. The sliding frame 82 is driven to slide to the right on the fixed frame 81 by the electric telescopic rod 84, so that the sliding frame 82 drives the sealing plug 83 to open. At this time, the condensate inside the drainage trough 88 is collected and flows into the drainage chamber 5. Then the sealing plug 83 is closed, and the second drainage pump 86 is started so that the water pump pipe 85 on the second drainage pump 86 draws out the condensate from the drainage chamber 5 and discharges the condensate through the discharge pipe 87. After use, due to the drop in temperature, condensation is likely to occur in the first air pipe 65, the second air pipe 66, and the arc-shaped air pipe 67. Due to its arc-shaped structure, the condensation in the arc-shaped air pipe 67 flows to both sides and enters the first air pipe 65 and the second air pipe 66. At this time, the three-way solenoid valve 69 is switched so that the first drain pump 610 draws out the condensation in the first air pipe 65 and the second air pipe 66 through the first water pipe 68 and discharges it through the drain pipe 611.
