[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a sealing cap for a reaction vessel. (Refer to...) Figure 2 and Figure 3 A reaction vessel sealing cover includes a sealing cover 1, a docking hole 2 is provided on the top of the sealing cover 1, and a reinforcing mechanism 3 is provided on the inner wall of the sealing cover 1.

[0024] The reinforcing mechanism 3 includes a sliding groove 301, which is formed on the inner wall of the sealing cover 1. A first toothed plate 302 is slidably connected to the inner wall of the sliding groove 301. A fixing block 303 is fixedly installed at one end of the first toothed plate 302. A gear 306 is rotatably connected to the inner wall of the sliding groove 301. A docking groove 304 is formed on the inner wall of the docking hole 2. The docking groove 304 communicates with the inner cavity of the sliding groove 301. A second toothed plate 305 is slidably connected to the inner cavity of the docking groove 304. Both the first toothed plate 302 and the second toothed plate 305 mesh with the teeth of the gear 306.

[0025] Reference Figure 2 The inner wall of the docking groove 304 is provided with a guide groove 4, and a guide block 5 is fixedly installed on the top of the second toothed plate 305. The surface of the guide block 5 is slidably connected with the inner cavity of the guide groove 4. Through the slidable connection between the guide groove 4 and the guide block 5, the movement of the second toothed plate 305 can be guided, so that the second toothed plate 305 can move laterally.

[0026] Reference Figure 2 A spring 6 is fixedly installed on the inner wall of the docking groove 304. One end of the spring 6 is fixedly connected to the surface of the second toothed plate 305. By setting the spring 6, when the sealing cover 1 is separated from the reactor, the bolt moves out of the inner cavity of the docking hole 2, thereby releasing the bolt from the pressure of the second toothed plate 305. Under the reaction force of the spring 6, the fixing block 303 can be automatically separated from the inside of the reactor.

[0027] Reference Figure 3A pressure-reducing pad 7 is fixedly installed on the surface of the fixing block 303. The surface of the pressure-reducing pad 7 is provided with triangular grooves 8. There are several triangular grooves 8. By setting the pressure-reducing pad 7, the pressure of the fixing block 303 on the inner wall of the reactor can be reduced. By setting the triangular grooves 8, the friction between the pressure-reducing pad 7 and the inner wall of the reactor can be increased, thereby improving the stability of the contact between the fixing block 303 and the inner wall of the reactor.

[0028] Reference Figure 2 A sealing ring 9 is fixedly installed at the bottom of the sealing cover 1. The sealing ring 9 is made of rubber. By setting the sealing ring 9, the sealing performance between the sealing cover 1 and the reaction vessel can be increased, and leakage can be reduced.

[0029] Reference Figure 1 and Figure 4 A connecting rod 10 is provided on both sides of the sealing cover 1. A threaded rod 11 is threadedly connected to the inner side of the connecting rod 10. An arc plate 12 is rotatably connected to one end of the threaded rod 11. A movable block 13 is fixedly installed on both sides of the sealing cover 1. The surface of the movable block 13 is slidably connected to the inner wall of the connecting rod 10. By setting the connecting rod 10 and rotating the threaded rod 11, the arc plate 12 is driven to move closer to the surface of the reactor. The connection between the sealing cover 1 and the two connecting rods 10 can fix the position of the connecting rod 10. By sliding the movable block 13 on the inner wall of the connecting rod 10, the installation of the sealing cover 1 can be guided to ensure accurate docking of the sealing cover 1 and the reactor.

[0030] Reference Figure 4 A support rod 14 is fixedly installed on the surface of the arc plate 12. The surface of the support rod 14 is slidably connected to the inner wall of the connecting rod 10. By setting the support rod 14, the movement of the arc plate 12 can be guided, so that the arc plate 12 can move laterally.

[0031] Working principle: Rotating the threaded rod 11 causes the arc-shaped plate 12 to move closer to the surface of the reactor. The connection between the sealing cover 1 and the two connecting rods 10 fixes the position of the connecting rods 10. The sliding block 13 on the inner wall of the connecting rods 10 guides the installation of the sealing cover 1, ensuring accurate alignment between the sealing cover 1 and the reactor. After alignment, bolts are used through the pre-drilled alignment hole 2 to fix the position of the sealing cover 1 and the reactor. After the threaded rod 11 enters the alignment hole 2, it forms an engagement with the second toothed plate 3. The compression of 05 causes the second toothed plate 305 to move into the inner cavity of the docking groove 304. At the same time, the transmission gear 306 starts to rotate, which can drive the first toothed plate 302 to move in the opposite direction, thereby driving the fixing block 303 to contact the inner wall of the reactor, providing an additional support point, making the sealing cover 1 more securely fixed on the reactor. This achieves secondary fixation of the position of the sealing cover 1 after it is fixed, further improving the stability of the sealing cover 1 after docking with the reactor, thus avoiding gaps between the sealing cover 1 and the reactor due to loose bolts.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
