[0020] 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 protection scope of the present utility model.

[0021] Please see Figure 1-7 This utility model provides a technical solution: a sealed storage vessel for methyl benzyl chloride, including a vessel shell 1, a feed pipe 2 is provided at the center of the top of the vessel shell 1, a cover 3 is provided at the top of the feed pipe 2 through a sealing mechanism, and a pressing mechanism is provided at the top of the cover 3.

[0022] The sealing mechanism includes a first mating groove 4, which is provided on the side of the top of the feed pipe 2. The outer side of the first mating groove 4 is engaged with the inner side of the rubber seal 6. The outer side of the rubber seal 6 is engaged with the inner side of the second mating groove 5, which is located on the inner side of the cover 3. The first mating groove 4, the second mating groove 5, and the side of the rubber seal 6 are all designed as stepped structures, which increases the sealing area at the connection between the feed pipe 2 and the cover 3 and improves the sealing performance between them.

[0023] The bottom of the first mating groove 4 has a limiting hole 8, which is engaged with the limiting rod 7. The limiting rod 7 and the limiting hole 8 are angularly distributed about the central axis of the rubber seal 6. The upper end of the limiting rod 7 is fixedly connected to the bottom of the rubber seal 6. Under the limiting of the limiting hole 8 and the limiting rod 7, the rubber seal 6 will not rotate, thus preventing misalignment between the rubber seal 6 and the first mating groove 4 and the second mating groove 5.

[0024] The clamping mechanism includes a first rotating shaft 9. Both sides of the feed pipe 2 are fixed with the first rotating shaft 9. The ends of the two first rotating shafts 9 are rotatably connected to both ends of the U-shaped movable frame 10 through bearings. A second rotating shaft 11 is threaded through the center of the top of the U-shaped movable frame 10. A screw block 12 is fixed to the side of the upper end of the second rotating shaft 11. The lower end of the second rotating shaft 11 is rotatably connected to the top of the axe cover 3 through bearings. By rotating the second rotating shaft 11, the axe cover 3 can be moved up or down. Moving down can squeeze the rubber seal 6 to seal the connection between the feed pipe 2 and the axe cover 3. Moving up can open the feed pipe 2.

[0025] There are two screw blocks 12 symmetrically distributed about the central axis of the second rotating shaft 11, which facilitates the rotation of the second rotating shaft 11.

[0026] A storage pipe 13 is provided at the center of the bottom of the reactor shell 1, and a manual valve 14 is installed on the storage pipe 13. The storage pipe 13 can be opened and closed by the manual valve 14, so that the methyl benzyl chloride stored inside the reactor shell 1 can be discharged through the storage pipe 13.

[0027] Working principle: When using the methylbenzyl chloride sealed storage vessel, firstly, manually rotate the second rotating shaft 11 by screwing block 12. Since the second rotating shaft 11 and the U-shaped movable frame 10 are threadedly connected, the second rotating shaft 11 drives the axe cover 3 to move upward and separate from the feed pipe 2. Then, rotate the U-shaped movable frame 10, the second rotating shaft 11 and the screwing block 12 by the first rotating shaft 9, so that the feed pipe 2 and the axe cover 3 are misaligned, so that the feed pipe 2 is fully opened.

[0028] When sealing the feed pipe 2 is required, firstly, the rubber seal 6 is fitted onto the first mating groove 4 on the feed pipe 2, so that the outer side of the first mating groove 4 engages with the inner side of the rubber seal 6. At the same time, the limiting rod 7 at the bottom of the rubber seal 6 engages with the limiting hole 8. Then, the U-shaped movable frame 10, the second movable frame 11, and the screw block 12 are rotated by the first rotating shaft 9, so that the axe cover 3 is located directly above the feed pipe 2. Then, the second rotating shaft 11 is manually rotated by the screw block 12. Since the second rotating shaft 11 and the U-shaped movable frame 10 are threadedly connected, the second rotating shaft 11 drives the axe cover 3 to move downward until the second mating groove 5 on the inner side of the axe cover 3 engages with the outer side of the rubber seal 6, and at the same time, the rubber seal 6 is pressed tight, thus completing the sealing between the feed pipe 2 and the axe cover 3.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
