[Specific implementation method]

[0020] The discharge port structure of the present invention is further described in detail below through specific embodiments.

[0021] See also Figures 1 to 3 A discharge port structure includes: a discharge port 1, a plug 2 and a suspension rod 3. The discharge port 1 includes a discharge port body 10 and a flange cover 11. The discharge port body 10 includes a forged pipe 100 and a flange 101. The flange 101 and the flange cover 11 are connected by a plurality of fixings. A winding gasket 12 is provided between the flange 101 and the flange cover 11, so as to have a good sealing performance. A handle 13 is provided on the flange cover 11. In this embodiment, the fixings are studs and nuts.

[0022] The plug 2 includes: a first connecting pipe 20, a second connecting pipe 21 and a sealing plate 22. The diameter of the second connecting pipe 21 is smaller than that of the first connecting pipe 20. The sealing plate 22 seals the bottom of the first connecting pipe 20 so as to form a receiving cavity 23 in the first connecting pipe 20. The receiving cavity 23 is provided with a plurality of Y-shaped anchor bolts 24 fixedly connected to the sealing plate 22. A casting material 25 is poured in the receiving cavity 23. The casting material 25 includes: a heating surface casting material 250 and an insulation surface casting material 251. The heating surface casting material 250 is located above the insulation surface casting material 251. A groove 252 is provided in the center of the casting material 25. The upper end of the second connecting pipe 21 is fixedly connected to the sealing plate 22. In this embodiment, the first connecting pipe 20 and the second connecting pipe 21 are welded to the sealing plate 22 respectively. A circular plate 26 fixedly connected to the sealing plate 22 is provided in the second connecting pipe 21, a hole is provided in the center of the sealing plate 22, a threaded hole 260 is provided in the center of the circular plate 26, the groove 252 of the castable 25, the hole on the sealing plate 22 and the threaded hole 260 on the circular plate 26 are interconnected, a ring plate 27 and an operating connecting pipe 28 are provided on the outer side of the second connecting pipe 21, the ring plate 27 and the second connecting pipe 21 are vertically arranged, four rib plates 29 are provided between the ring plate 27 and the second connecting pipe 21, and the rib plates 29 are respectively welded to the ring plate 27 and the second connecting pipe 21.

[0023] At least one slot 270 is provided at the edge of the ring plate 27. In the present embodiment, there are two slots 270, which are arranged at 180 degrees. A stopper 102 is provided on the inner wall of the discharge port body 10 to match the slot 270 at the edge of the ring plate 27. One end of the suspension rod 3 is provided with an external thread section to match the central threaded hole 260 of the circular plate 26. Ceramic fiber felt 4 is filled between the flange cover 11 and the plug 2. Ceramic fiber rope 5 is filled in the gap between the discharge port body 10 and the plug 2, so as to have good thermal insulation performance.

[0024] During installation, first insert the plug 2 from the outside of the discharge port 1 into the discharge port 1, then pass a suspension rod 3 with an external threaded section on the head through the groove 252 in the center of the casting material 25 and the hole on the sealing plate 22 until it is tightened with the threaded hole 260 in the center of the circular plate 26, and drive the plug 2 to move to the inside of the discharge port 1 through the suspension rod 3. When the ring plate 27 of the plug 2 moves to the position of the stopper 102 on the inner wall of the discharge port body 10, rotate the plug 2 until the groove 270 on the ring plate 27 is at the same position as the stopper 102 in the discharge port body 10, so that the ring plate 27 can pass through the stopper 102. After the ring plate 27 passes through the block 102, the plug 2 rotates 180°, so that the groove 270 on the ring plate 27 is staggered with the block 102 at the inner wall of the discharge port main body 10, thereby realizing the locking function of the plug 2, that is, after the plug 2 is installed in the discharge port 1, the plug 2 will not fall out of the discharge port 1 when there is no external force operation. After the plug 2 is installed, the suspension rod 3 is removed from the inside of the reaction vessel, and the ceramic fiber rope 5 is filled in the groove 252 in the center of the casting material 25 and the gap between the plug 2 and the discharge port 1. Finally, the ceramic fiber felt 4 is filled in the discharge port 1 and the discharge port 1 is sealed with the Farage cover 11.

[0025] When unloading, first open the flange cover 11, remove the ceramic fiber felt 4 in the discharge port 1, and then rotate the plug 2 by rotating the operating pipe 28 until the groove 270 on the ring plate 27 and the stopper 102 on the inner wall of the discharge port body 10 are in the same position. At this time, the plug 2 can be directly taken out from the discharge port 1 to discharge the filler in the reaction container.

[0026] In summary, the discharge port structure of the present invention greatly improves the heat insulation performance of the discharge port by arranging a castable in the plug and filling ceramic fibers in the gap, which can prevent the high temperature in the reaction container from affecting the strength of the discharge port. In addition, the present invention makes the plug easy to install and disassemble by structural modification of the plug, and the plug has a locking function after being installed in the discharge port, thereby greatly improving the safety performance.

[0027] The above-mentioned embodiments are only illustrative of the principles and effects of the invention, as well as some embodiments of its application, and are not intended to limit the invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and all of these belong to the protection scope of the invention.
