[Specific implementation method]

[0017] The following is a further detailed description of the discharge port plug of the present invention through specific embodiments.

[0018] Ginseng Figure 1 and Figure 2As shown, a discharge port plug includes: a first connecting pipe 1, a second connecting pipe 2 and a sealing plate 3, wherein the diameter of the second connecting pipe 2 is smaller than that of the first connecting pipe 1. The sealing plate 3 seals the bottom of the first connecting pipe 1 so as to form a receiving chamber 4 in the first connecting pipe 1, wherein the receiving chamber 4 is provided with four Y-shaped anchor bolts 5 welded to the sealing plate 3, and a casting material 6 is poured in the receiving chamber 4, wherein the casting material 6 includes: a heating surface casting material 60 and an insulating surface casting material 61, wherein the heating surface casting material 60 is located above the insulating surface casting material 61. A groove 62 is provided in the center of the casting material 6, and the upper end of the second connecting pipe 2 is fixedly connected to the sealing plate 3. In this embodiment, the first connecting pipe 1 and the second connecting pipe 2 are welded to the sealing plate 3 respectively. A circular plate 7 fixedly connected to the sealing plate 3 is provided in the second connecting pipe 2. A hole (not shown) is provided in the center of the sealing plate 3. A threaded hole 70 is provided in the center of the circular plate 7. The groove 62 of the castable 6, the hole on the sealing plate 3 and the threaded hole 70 on the circular plate 7 are interconnected. A ring plate 8 and an operating connecting pipe 9 are provided on the outer side of the second connecting pipe 2. The ring plate 8 and the second connecting pipe 2 are arranged vertically. Four rib plates 80 are provided between the ring plate 8 and the second connecting pipe 2. The rib plates 80 are welded to the ring plate 8 and the second connecting pipe 2 respectively. At least one slot 81 is provided at the edge of the ring plate 8. In this embodiment, the number of the slots 81 is two, and the two slots 81 are arranged at 180 degrees. A stopper (not shown) matching the slot 81 at the edge of the ring plate 8 is provided in the discharge port.

[0019] During installation, first insert the plug into the discharge port from the outside of the discharge port, then pass a suspension rod with an external threaded section on the head through the groove 62 in the center of the castable 6 and the hole on the sealing plate 3 until it is tightened with the threaded hole 70 in the center of the circular plate 7, and drive the plug to move to the inside of the discharge port through the suspension rod. When the ring plate 8 of the plug moves to the stopper position in the discharge port, rotate the plug until the slot 81 on the ring plate 8 is at the same position as the stopper in the discharge port, so that the ring plate 8 can pass through the stopper, and the ring After the plate 8 passes through the block, the plug is rotated 180°, so that the slot 81 on the ring plate 8 is staggered with the block in the discharge port, thereby realizing the locking function of the plug, that is, after the plug is installed in the discharge port, the plug will not fall out of the discharge port when there is no external force. After the plug is installed, the suspension rod is removed from the inside of the reaction vessel, and the ceramic fiber is filled in the groove 62 in the center of the castable 6 and the gap between the plug and the discharge port. Finally, the discharge port is filled with ceramic fibers and the discharge port is sealed with a Farad cover.

[0020] When unloading, first open the flange cover, remove the ceramic fiber in the discharge port, and then rotate the plug by rotating the operating pipe 9 until the groove 81 on the ring plate 8 and the block in the discharge port are in the same position. At this time, the plug can be directly taken out from the discharge port to discharge the filler in the reaction vessel.

[0021] In summary, the present invention makes structural modifications to the plug in the discharge port so that the plug has good heat insulation performance, thereby preventing the high temperature in the cylinder from affecting the strength of the discharge port. In addition, the plug in the present invention has a locking function after being installed in the discharge port, thereby greatly improving the safety performance.

[0022] 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.
