DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0023] In the drawings, the same reference numerals all refer to the same components.

[0024] Example 1

[0025] like Figure 1-4 As shown, it includes a steam curing kiln body 1, and the two inner side walls of the steam curing kiln body 1 are provided with evenly distributed steam nozzles 101, the steam nozzles 101 are commonly connected to an air outlet pipe 104, and a solenoid valve 105 is provided at one end of the air outlet pipe. An electric lifting door 102 is provided at the opening of the steam curing kiln body 1, and a conveying device 2 is provided in the center of the steam curing kiln body 1. Support blocks 3 are provided on both sides of the conveying device 2. Trapezoidal grooves 4 are provided on the opposite sides of the tops of the two support blocks 3. A water drop processing device 5 is provided on the top of the steam curing kiln body 1, and the water drop processing device 5 includes two sides. The movable slide rail 6 and the central water drop removal device 7, the water drop removal device 7 includes a connecting disk 8, a connecting scraper 9 is provided on the top of the connecting disk 8, brushes 10 are provided on both sides of the connecting scraper 9, a connecting hose 11 is provided on one side of the bottom of the connecting disk 8, connecting sliders 12 are provided on both sides of the connecting disk 8, and transmission threaded holes 13 are opened through the surface of the connecting slider 12. A connecting groove 14 is provided at the bottom of the movable slide rail 6, and the connecting groove 14 is slidably connected to the connecting slider 12. A connecting screw rod 15 is provided inside the connecting groove 14, and a driving motor 16 is provided at one end of the movable slide rail 6.

[0026] Furthermore, the other end of the connecting hose 11 passes through the side wall of the steaming kiln body 1. A storage box 103 is provided on one side of the steaming kiln body 1. The connecting hose 11 passes through the interior of the storage box 103. After the water droplets on the top of the steaming kiln body 1 are removed and collected by the water droplet processing device 5, the water droplets gather on the surface of the connecting plate 8, and the water droplets will flow into the interior of the storage box 103 through the connecting hose 11 for collection.

[0027] A contact block 91 made of rubber material is provided on the top of the connecting scraper block 9. The contact block 91 contacts the top wall of the steaming kiln body 1, and the connecting slider 12 is driven to slide inside the connecting slide groove 14 through the connecting screw rod 15, so that it drives the connecting disk 8 to move. The contact block 91 contacts the top wall of the steaming kiln body 1. When the connecting disk 8 moves, the contact block 91 scrapes off the water droplets on the top wall of the steaming kiln body 1 and collects the water droplets on the top of the steaming kiln body 1.

[0028] The contact block 91 is U-shaped, and the tops of both sides of the contact block 91 are set to pointed cones. Leakage holes 92 are set on both sides of the contact block 91. The U-shaped contact block 91 can scrape the water droplets on the top wall of the steaming kiln body 1 for the second time, so that the water droplets on the top can be removed more cleanly.

[0029] The movable slide rails 6 are embedded in the inner walls on both sides of the steaming kiln body 1, and water drops will not adhere to the bottom of the movable slide rails 6.

[0030] A control panel 106 is provided on one side of the steaming kiln body 1 , and the control panel 106 is electrically connected to the solenoid valve 105 , the electric lifting door 102 and the driving motor 16 .

[0031] The driving motor 16 is transmission-connected to the connecting screw.

[0032] Specifically, when in use, the subway pipe segment is placed inside the trapezoidal groove 4 on the top of the support block 3. The two opposite trapezoidal grooves 4 clamp and limit the arc-shaped subway pipe segment to prevent it from displacement. The solenoid valve 105 is opened by operating the control panel 106. The steam connected to the solenoid valve 105 is discharged from the inside of the steam nozzle 101 through the outlet pipe 104. The steam heats and shapes the subway pipe segment. The control panel 106 is controlled to make the driving motor 16 rotate forward. The driving motor 16 rotates forward to drive the connecting screw rod 15 to rotate forward. The connecting screw rod 15 is connected to the transmission threaded hole 13. When the connecting screw rod 15 rotates, it drives the connecting slider 12 to slide inside the connecting slot 14, so that it drives the connecting slider 12 to slide inside the connecting slot 14. The connecting plate 8 moves, and the contact block 91 contacts the top wall of the steaming kiln body 1. When the connecting plate 8 moves, the brush 10 cleans the water droplets on its top surface for the first time. The U-shaped contact block 91 can scrape off the water droplets on the top wall of the steaming kiln body 1 for the second time. After the contact block 91 scrapes, the brush 10 on the other side will clean the top wall of the steaming kiln body 1 again. The scraped water droplets will be caught by the connecting plate 8, which can remove the water droplets on the top more cleanly. The water droplets falling to the opening of the contact block 91 will flow to the inside of the connecting plate 8 through the leakage hole 92. The connecting plate 8 collects the water droplets on the top of the steaming kiln body 1, and the collected water droplets flow into the storage box 103 through the connecting hose 11 for storage.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
