Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a hazardous chemical product reaction vessel with good sealing performance. Background Technology

[0002] In a broad sense, a reaction vessel is a container where physical or chemical reactions occur. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. Reaction vessels are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation.

[0003] Currently, in order to maintain their airtightness, existing hazardous chemical reaction vessels are connected and fixed with a large number of bolts and nuts around the vessel body and lid. This makes subsequent inspection and maintenance difficult, requiring tools and a long time to complete the disassembly and assembly of all bolts and nuts, making the process quite cumbersome. Utility Model Content

[0004] This disclosure relates to a well-sealed hazardous chemical product reaction vessel, which solves the problem that in the application of existing hazardous chemical product reaction vessels, in order to maintain their own sealing, the vessel body and the vessel cover are connected and fixed by a large number of bolts and nuts, which makes subsequent maintenance difficult and requires tools and a long time to complete the disassembly and assembly of all bolts and nuts, and the process is quite cumbersome.

[0005] In a first aspect, this disclosure provides a well-sealed hazardous chemical product reaction vessel, specifically comprising: a vessel body, a vessel lid, a sealing ring, a motor, a mixing shaft, a screw ring, a force-bearing ring, a tie rod, and bolts; the vessel lid is fastened to the top of the vessel body, and a sealing ring is installed at the interval between the vessel lid and the vessel body, with the top side of the sealing ring contacting the vessel lid and the bottom side of the sealing ring contacting the vessel body; a motor is installed on the top of the vessel lid, and a mixing shaft is installed inside the vessel body, with the motor's drive shaft connected to the mixing shaft, and a paddle wheel provided at the bottom end of the mixing shaft; a screw ring is connected to the outside of the vessel body, and a force-bearing ring is connected to the outside of the screw ring, with a tie rod connected in a circumferential shape to the outside of the force-bearing ring, and the tie rod is connected to the vessel body and the vessel lid; bolts are connected inside the screw ring.

[0006] Furthermore, a positioning groove is provided in a circumferential shape on the inner side of the vessel body, and a positioning block is provided in a circumferential shape at the bottom of the vessel lid, with the positioning block inserted into the positioning groove.

[0007] Furthermore, the top of the vessel body is provided with a lower connecting groove in a circumferential shape, and the number of lower connecting grooves is the same as that of positioning grooves. The bottom of the vessel lid is provided with an upper connecting groove in a circumferential shape, and the number of upper connecting grooves is the same as that of positioning blocks. The upper connecting grooves are connected to the lower connecting grooves. The positioning blocks are inserted and engaged with the positioning grooves to prevent the vessel lid from rotating, so that the upper connecting grooves and the lower connecting grooves are kept in precise communication.

[0008] Furthermore, the vessel body is machined with external threads, a threaded ring is threaded to the outside of the vessel body, and a handle is provided outside the threaded ring.

[0009] Furthermore, the outer surface of the spiral ring is provided with an annular groove, and the force-bearing ring is rotatably connected within the annular groove.

[0010] Furthermore, the top of the pull rod is located in the upper and lower connecting grooves in a connected state, and the bottom of the pull rod is rotatably connected to the force-bearing ring. When the top of the pull rod is located in the upper and lower connecting grooves, the screw ring is rotated, and the screw ring drives the pull rod to move downward through the force-bearing ring, applying downward pressure to the lid, so that the lid and the sealing ring are in close contact, and the sealing ring and the lid body are in close contact.

[0011] Furthermore, the screw ring has two screw holes inside, and the bolt is threaded into the screw holes. The inner end of the bolt contacts the outer thread of the vessel body. After the screw ring is tightened, the bolt is connected into the screw holes so that the inner end of the bolt contacts the vessel body. The screw ring is fixed by the bolt, which effectively prevents the screw ring from loosening.

[0012] This utility model provides a well-sealed hazardous chemical product reaction vessel, which has the following beneficial effects:

[0013] In use, this invention uses a positioning block that engages with a positioning groove to prevent the lid from rotating, ensuring precise connection between the upper and lower connecting grooves. When the top of the pull rod is positioned within the upper and lower connecting grooves, rotating the screw ring causes it to move downwards via the force ring, applying downward pressure to the lid. This ensures tight contact between the lid and the sealing ring, and between the sealing ring and the vessel body, guaranteeing the internal sealing of the reactor. This makes assembly simpler and more time-saving.

[0014] In addition, after the screw ring is tightened, the bolt is connected into the screw hole so that the inner end of the bolt contacts the reactor body. The screw ring is fixed by the bolt, which effectively prevents the screw ring from loosening and further ensures the internal sealing of the reactor. When the reactor needs to be disassembled for maintenance, the bolt is removed first, and the screw ring is rotated in the opposite direction. The screw ring drives the pull rod to move upward through the force ring. Rotating the pull rod separates the pull rod from the upper and lower connecting grooves, and the reactor cover can be moved upward to separate the reactor cover from the top of the reactor body. The operation is simple and quick.

[0027] This utility model proposes a well-sealed hazardous chemical product reaction vessel, comprising: a vessel body 1, a vessel cover 2, a sealing ring 3, a motor 4, a mixing shaft 5, a screw ring 6, a force-bearing ring 7, a tie rod 8, and bolts 9; the vessel cover 2 is fastened to the top of the vessel body 1, and a sealing ring 3 is installed at the interval between the vessel cover 2 and the vessel body 1, with the top side of the sealing ring 3 contacting the vessel cover 2 and the bottom side of the sealing ring 3 contacting the vessel body 1; the motor 4 is installed on the top of the vessel cover 2, and the mixing shaft 5 is installed inside the vessel body 1, with the drive shaft of the motor 4 connected to the mixing shaft 5, and a paddle wheel 51 provided at the bottom end of the mixing shaft 5; a screw ring 6 is connected to the outside of the vessel body 1, and a force-bearing ring 7 is connected to the outside of the screw ring 6, with the force-bearing ring 7 having an external shape. A pull rod 8 is connected in a ring shape, and the pull rod 8 is connected to the vessel body 1 and the vessel cover 2. A bolt 9 is connected inside the screw ring 6. A positioning groove 11 is provided in a ring shape on the inner side of the vessel body 1. A positioning block 21 is provided in a ring shape at the bottom of the vessel cover 2, and the positioning block 21 is inserted into the positioning groove 11. A lower connecting groove 12 is provided in a ring shape on the top of the vessel body 1. The number of lower connecting grooves 12 is the same as the number of positioning grooves 11. An upper connecting groove 22 is provided in a ring shape at the bottom of the vessel cover 2. The number of upper connecting grooves 22 is the same as the number of positioning blocks 21. The upper connecting groove 22 is connected to the lower connecting groove 12. The positioning block 21 is inserted and engaged with the positioning groove 11 to prevent the vessel cover 2 from rotating, so that the upper connecting groove 22 and the lower connecting groove 12 are precisely connected.

[0028] In this embodiment of the disclosure, the outer surface of the vessel body 1 is machined with external threads, the screw ring 6 is threadedly connected to the outer surface of the vessel body 1, the screw ring 6 is provided with a handle 61, the screw ring 6 is provided with an annular groove 62, the force ring 7 is rotatably connected to the annular groove 62, the top of the pull rod 8 is located in the upper connecting groove 22 and the lower connecting groove 12 in a connected state, and the bottom of the pull rod 8 is rotatably connected to the force ring 7.

[0029] Using the above technical solution, when the top of the pull rod 8 is located in the upper connecting groove 22 and the lower connecting groove 12, the screw ring 6 is rotated. The screw ring 6 drives the pull rod 8 to move downward through the force ring 7, applying downward pressure to the vessel cover 2, so that the vessel cover 2 is in close contact with the sealing ring 3, and the sealing ring 3 is in close contact with the vessel body 1, ensuring the internal sealing of the reactor, and making the assembly simpler and more time-saving.

Next, the pull rod 8 is rotated so that the top of the pull rod 8 is located within the upper connecting groove 22 and the lower connecting groove 12. The screw ring 6 is rotated, and the screw ring 6 drives the pull rod 8 to move downward through the force ring 7, applying downward pressure to the lid 2, so that the lid 2 and the sealing ring 3 are in close contact, and the sealing ring 3 and the vessel body 1 are in close contact. Contact is made to ensure the internal sealing of the reactor. After the screw ring 6 is tightened, the bolt 9 is connected into the screw hole 63 so that the inner end of the bolt 9 contacts the reactor body 1. The screw ring 6 is fixed by the bolt 9, which effectively prevents the screw ring 6 from loosening. When the reactor needs to be disassembled for maintenance, the bolt 9 is removed first, and the screw ring 6 is rotated in the opposite direction. The screw ring 6 drives the pull rod 8 to move upward through the force ring 7. The pull rod 8 is rotated to separate the pull rod 8 from the upper connecting groove 22 and the lower connecting groove 12. Then the reactor cover 2 can be moved upward to separate the reactor cover 2 from the top of the reactor body 1.
