Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, and in particular to a sealing structure for the discharge of a chemical reaction vessel. Background Technology
[0002] In a broad sense, a chemical reactor 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. When chemical materials need to be mixed and stirred, they are placed in the reactor to produce a chemical reaction. Currently, the discharge end of most reactors is controlled by valves. However, if a mechanical failure occurs, the discharge valve may not open and close properly, easily leading to leakage, which is detrimental to the use of the reactor. Therefore, we propose a sealing structure for the discharge of a chemical reactor. Utility Model Content
[0003] To address the aforementioned problems, this invention provides a sealing structure for the discharge of a chemical reactor. This invention solves the problem that existing reactors often rely on valves for discharge control, but if a mechanical malfunction occurs, the valve may fail to open and close properly, leading to leakage and hindering the reactor's operation.
[0004] This utility model discloses a chemical reactor discharge sealing structure, comprising a reactor body, a discharge pipe located at the lower center of the reactor body, a sealing cylinder located below the discharge pipe, a first flange located below the discharge pipe, a second flange located above the sealing cylinder, a fixing ring located at the upper part of the sealing cylinder, a groove matching the fixing ring located inside the discharge pipe, a limiting platform located at the upper end of the sealing cylinder, a threaded rod inserted into the lower center of the sealing cylinder, the threaded rod being movably connected to a cover plate at its upper part, a sealing block matching the limiting platform located at the upper center of the cover plate, a first sealing ring located between the cover plate and the limiting platform, and a guide pipe located at the lower end of one side of the sealing cylinder.
[0005] In the above scheme, the discharge pipe is provided with a second sealing ring on the side wall of the slot.
[0006] In the above scheme, the upper end of the limiting platform is provided with a downward inclined surface.
[0007] In the above scheme, the inner wall of the sealing cylinder is provided with four guide rails arranged in a matrix, and the cover plate is provided with a limiting groove that matches the guide rails.
[0008] In the above scheme, the threaded rod is fixedly connected to the turntable at the bottom.
[0009] In the above scheme, the first flange and the second flange are fixedly connected by bolts.
[0010] The advantages and beneficial effects of this utility model are as follows: This utility model provides a discharge sealing structure for a chemical reactor. A threaded rod pushes the cover plate to move vertically. When the cover plate moves upward, it pushes the sealing block, which moves to the middle of the limiting platform. Through the cooperation between the sealing block and the limiting platform, the sealing block can seal the upper end of the sealing cylinder. When the cover plate is separated from the limiting platform, the material inside the reactor body can be discharged through the connected sealing cylinder and the guide pipe. This sealing structure is simple in structure, easy to operate, and has a good sealing effect. It effectively avoids leakage caused by insufficient sealing tightness, thus improving the practicality of the reactor. Attached Figure Description

A sealing block 12 matching the limiting platform 9 is provided in the middle of the square. A first sealing ring 13 is provided between the cover plate 11 and the limiting platform 9. The first sealing ring 13 effectively increases the sealing between the cover plate 11 and the limiting platform 9. When the threaded rod 10 is rotated, the threaded rod 10 can push the cover plate 11 to move vertically. When the cover plate 11 moves upward, the cover plate 11 pushes the sealing block 12. The sealing block 12 moves to the middle of the limiting platform 9. Through the mutual cooperation between the sealing block 12 and the limiting platform 9, the sealing block 12 can seal the upper end of the sealing cylinder 3. A guide pipe 16 is provided at the lower end of one side of the sealing cylinder 3. The material entering the sealing cylinder 3 can be discharged through the guide pipe 16.
[0023] The discharge pipe 2 is provided with a second sealing ring 8 on the side wall of the slot 7. The second sealing ring 8 effectively increases the sealing between the discharge pipe 2 and the sealing cylinder 3.

[0025] The inner wall of the sealing cylinder 3 is provided with four guide rails 14 arranged in a matrix. The cover plate 11 is provided with a limiting groove 15 that matches the guide rails 14. The guide rails 14 are located inside the limiting groove 15. Through the mutual cooperation between the guide rails 14 and the limiting groove 15, the movement stability of the cover plate 11 is effectively improved.
[0026] The threaded rod 10 is fixedly connected to the turntable 17 at the bottom, and the turntable 17 makes it easier to rotate the threaded rod 10.
[0027] The first flange 4 and the second flange 5 are fixedly connected by bolts 18. The bolts 18 make it easier to install and disassemble the first flange 4 and the second flange 5.
[0028] Specifically, in this utility model, when sealing the outlet end of the reactor body 1, the turntable 17 is rotated, the turntable 17 drives the threaded rod 10 to rotate, and the threaded rod 10 pushes the cover plate 11 to move vertically. When the cover plate 11 moves upward, the cover plate 11 pushes the sealing block 12, and the sealing block 12 moves to the middle of the limiting platform 9. Through the mutual cooperation between the sealing block 12 and the limiting platform 9, the sealing block 12 can seal the upper end of the sealing cylinder 3. When the cover plate 11 is separated from the limiting platform 9, the material inside the reactor body 1 can be discharged through the connected sealing cylinder 3 and the guide pipe 16.
