At the same time, the remaining steam is controlled by the opening and closing of the valve, and flows back to the secondary steam pipe and is input into the forming mechanism again for heating, thereby forming the secondary utilization of steam, effectively reducing the steam consumption and reducing energy consumption.

[0020] Preferably, the structures of the first arc-shaped hot plate, the second arc-shaped hot plate and the third arc-shaped hot plate are all the same. The first arc-shaped hot plate includes a hot plate main body. A telescopic groove is formed through the top of the hot plate main body. A heat transfer device is fixedly arranged at the position of the telescopic groove on the top of the hot plate main body. Grooves are formed on both sides of the bottom of the telescopic groove, and torsion springs are fixedly arranged in the two grooves. Lower pressing plates are fixedly arranged at the bottoms of the two torsion springs, and the lower pressing plates move in the two grooves.

[0021] By adopting the above technical solution, the lower pressing plate contacts with the steam and is heated, so that the heat transfer device receives the heat and extends, thereby pressing down to apply a downward pressure to the relative ends of the two rotating plates, causing the two rotating plates to rotate. When the lower pressing plate stops being heated, the two torsion springs extend, thereby pushing the lower pressing plate back to the original position.

[0022] Preferably, movable grooves are formed on both sides of the telescopic groove inside the hot plate main body. Expansion plates are movably arranged in the two movable grooves. Leakage grooves are formed on the opposite sides of the two expansion plates.

[0023] By adopting the above technical solution, the formation of the movable grooves provides space for the movement of the expansion plates and limits the expansion plates at the same time, so that the expansion plates can only move longitudinally up and down. The leakage grooves formed on the surfaces of the two expansion plates guide the condensed steam water to flow obliquely downward, so as to be conveniently collected by the pipeline structure.

[0024] Preferably, communication ports are formed in the two movable grooves communicating with the telescopic groove. Rotating rods are fixedly arranged in the two communication ports. Rotating plates are rotatably connected to the surfaces of the two rotating rods. The two rotating plates are respectively rotatably connected to the two expansion plates. The bottom of the hot plate main body is provided with a guiding surface on the side of the pipeline connection.

[0025] By adopting the above technical solution, the formation of the communication ports provides space for the installation of the rotating rods and the rotation of the rotating plates, so that one end of the rotating plate is subjected to pressure and rotates around the rotating rod, thereby applying a downward thrust to the top of the expansion plate. At the same time, the guiding surface plays a guiding role for the inflow of the steam water, guiding the condensed steam water into the pipeline.

[0026] In summary, the present invention includes at least one of the following beneficial technical effects:

[0027] 1. The main steam pipe is used for preliminary transmission heating with the forming mechanism. Then, the used steam is input into the secondary steam pipe through the exhaust valve for secondary transmission heating of the forming mechanism. During the input process, the steam contacts multiple water-vapor separation mechanisms, thereby forming water-vapor separation, reducing the water content in the steam, and discharging the water through the recovery pipeline to the external collection, thus improving the steam dryness in the secondary steam pipe, further increasing the steam temperature, facilitating the secondary transmission heating of the forming mechanism, thereby forming secondary recovery and reuse of the steam, and effectively reducing energy consumption.

[0028] 2. By means of the lower pressing plate being directly in contact with the steam at the pipe outlet, heat is transmitted to warm the inside of the telescopic groove. At the same time, it moves upward under the thrust of the steam. The heat transmission device receives the heat and causes the telescopic end to contract, following the movement of the lower pressing plate. The movement of the lower pressing plate drives the two expansion plates to unfold, thereby covering both sides of the pipe outlet, forming a sealed environment and increasing the contact area between the steam and the plate surface, effectively ensuring the sealed flow of the steam and simultaneously improving the efficiency of water-vapor separation.

[0058] The implementation principle of an energy-saving steam pipeline system according to an embodiment of the present invention is as follows: when using this device, personnel start an external boiler for heating. The generated water vapor is discharged upward into the T-shaped turning part of the steam main pipe 1 and enters it for preliminary differentiation. Part of the steam is discharged from the left side and contacts the arc-shaped hot plate one 61, generating water vapor separation and reducing the gas flow rate to form a reflux. During the reflux process, the water in the steam contacts the inner wall of the arc-shaped hot plate one 61 to form condensation, and flows into the discharge main pipe 21 through the pipeline. And at this time, the steam trap seven 57 is in an open state. Then the remaining steam moves along the right side of the steam main pipe 1;

[0059] At this time, the on-off valve one 11, the on-off valve two 12 and the pneumatic valve one 91 are all in a closed state, so that the steam is discharged downward from the steam main pipe 1 into the branch and thus enters the inner parts of the inner paper heating cylinder 41, the pressure roller 42 and the upper corrugating roller 43. The inner paper heating cylinder 41 receives heat to preliminarily heat the corrugated paper transported on its surface for subsequent deformation. The pressure roller 42 receives heat to extrude the corrugated paper. While extruding, the inside of the pressure roller 42 is heated to ensure the density of the extruded corrugated paper. Then, the upper corrugating roller 43 abuts against and extrudes the lower corrugating roller 44 to form the corrugated paper.

[0060] During the forming process of corrugated paper, the steam inside the inner paper hot cylinder 41, pressure roller 42, and upper corrugating roller 43 is respectively led out through the first drain pipe 22, the second drain pipe 23, and the third drain pipe 24. And during the leading-out process, it is separated by the first steam trap 51, the second steam trap 52, and the third steam trap 53 to discharge the steam water and block the steam. The discharged steam water converges towards the discharge main pipe 21 and is finally discharged into the external recycling machine. The remaining steam is located in the steam main pipe 1 and is drawn by the vent valve 10 and injected into the vent pipeline 3. At this time, the high exhaust pneumatic valve 93 operates to draw steam and transport it into the secondary steam pipe 8. During the drawing process, the steam contacts the inner wall of the vent pipeline 3, so that part of the steam is discharged from the vent pipeline 3 to the external boiler for reheating. The steam entering the secondary steam pipe 8 is injected into the upper corrugating roller 43 and the lower corrugating roller 44 along the pipeline for secondary utilization;

[0061] Then the operator sets the first on-off valve 11 and the second on-off valve 12 to the open state, so that the secondary steam and the steam in the steam main pipe 1 are discharged into the inner paper hot cylinder 45 to perform the final extrusion treatment on the corrugated paper. During the extrusion process, the steam is discharged from the secondary steam pipe 8 and contacts the third arc-shaped hot plate 63, thus forming steam-water separation. The separated steam water is led into the fourth drain pipe 25 through the fifth drain pipe 26. At the same time, the inner paper hot cylinder 45 discharges steam into the fourth drain pipe 25 during operation, so that the discharged steam water is discharged to the recycling machine through the discharge main pipe 21.

[0062] During the contact process between the steam and the third arc-shaped hot plate 63, the lower pressing plate 613 is in direct contact with the steam, forming a thrust to move upward along the telescopic groove 65. At the same time, the heat of the steam is conducted to the heat transfer device 13. The heat transfer device 13 receives the heat and causes the telescopic end to contract. Cooperating with the thrust received by the lower pressing plate 613, the lower pressing plate 613 moves upward with the steam, thus applying an upward thrust to the relative ends of the two rotating plates 69, causing the two rotating plates 69 to rotate around the rotating rod 68, thereby driving the two expansion plates 610 to move downward to cover the position of the pipeline docking interface, so that the steam is input into the recovery pipeline 2 along the arc surface at the bottom of the hot plate main body 64. The contact area with the steam is increased through the two side expansion plates 610, and the steam water generated by the contact of the steam flows into the recovery pipeline 2 through the leakage groove 611, attaching to improve the efficiency of steam-water separation and increase the secondary utilization rate of the steam.

[0063] The above are only optional embodiments of the present disclosure and are not used to limit the present disclosure. For those skilled in the art, various changes and modifications can be made to the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure.
