Description

Technical Field

[0001] This utility model relates to the field of distillation kettle technology, specifically a distillation kettle for the preparation of bromoacetic acid. Background Technology

[0002] Patent publication number CN205913798U discloses a distillation kettle, the shell of which includes an upper head, a hollow cylindrical body, and a lower head; the upper head, the cylindrical body, and the lower head are connected in pairs via flanges; a demister is provided at the top of the cylindrical body; a steam outlet is provided in the middle of the upper head; the cylindrical body has a heat transfer oil inlet, a heat transfer oil outlet, and a feed inlet; a set of spiral heat transfer oil heat exchange tubes communicating with the heat transfer oil inlet and outlet are located inside the cylindrical body; the heat transfer oil heat exchange tubes are located at the lower interior of the cylindrical body; the feed inlet is located on the upper side of the cylindrical body, penetrates the cylindrical body, and then turns vertically downwards, extending from the inside of the spiral heat transfer oil heat exchange tubes to the lower interior of the cylindrical body. The distillation kettle of this invention has a demister at the top, which can promptly remove foam generated by the material during the separation process, preventing the raw material from being discharged with the gas; the flange connection facilitates disassembly and cleaning; and the angled design of the feed inlet effectively prevents flooding.

[0003] In the above-disclosed structure, the flanges are mostly connected by bolts, which is inconvenient to disassemble and therefore takes a long time to clean. At the same time, when preparing bromoacetic acid, the material is easy to remain on the inner wall of the reactor, so improvements are needed. Utility Model Content

The output end of the first drive motor is connected to the main shaft through a first pulley assembly, and the output end of the second drive motor is connected to the second sleeve through a second pulley assembly.

[0010] To facilitate more stable movement of the connecting frame and connecting arm, the improvement of this utility model is that a telescopic rod is connected between the bottom wall of the connecting arm and the top wall of the operating table.

[0011] To improve the sealing between the lower and upper vessel bodies, the present invention includes an improvement where the top wall of the lower vessel body has an inclined surface with multiple sets of sealing strips, and the bottom wall of the upper vessel body has an inclined groove.

The vessel body is mounted on the top wall of the operating platform 1. The vessel body includes a lower vessel body 2 and an upper vessel body 3. The bottom wall of the lower vessel body 2 is fixedly connected to the top wall of the operating platform 1. A hydraulic cylinder 8 is fixedly mounted on the top wall of the operating platform 1 at the rear of the vessel body. A connecting frame 6 is fixedly mounted on the output end of the hydraulic cylinder 8. Connecting arms 7 are fixedly mounted on the front side wall of the connecting frame 6 on both sides of the upper vessel body 3. Fixing frames 5 are fixedly mounted on the side of the connecting arms 7 near the upper vessel body 3. A vessel handle 4 is fixedly mounted on the left and right side walls of the upper vessel body 3. The right vessel handle 4 is rotatably connected to the corresponding fixing frame 5. The top wall of the left fixing frame 5 is provided with... The positioning component includes a stirring component inside the vessel. The hydraulic cylinder 8 moves the connecting frame 6 and connecting arm 7 upward, separating the lower vessel 2 and the upper vessel 3. By releasing the restriction on the upper vessel 3 through the positioning component, the upper vessel 3 can be rotated out to one side of the fixing frame 5, facilitating the cleaning of the interior of the upper vessel 3. The stirring component can stir the material for preparing bromoacetic acid, reducing material residue. This structure is easier to clean than traditional distillation vessels for preparing bromoacetic acid. It should be noted that both the lower and upper vessels are embedded with electric heating layers, which are existing publicly available technologies and will not be described in detail.

[0023] Please see Figure 1 , 2 5 and 6, the above-mentioned positioning components can be any one of them. This application provides an embodiment in which the positioning components include an electromagnet 17, a return spring 20, a magnetic block 19, and a positioning pin 18. A positioning seat 10 is fixedly provided on the top wall of the left fixed frame 5. The positioning seat 10 is provided with an inner cavity. A through hole penetrating the fixed frame 5 is provided on the bottom wall of the inner cavity. A positioning hole adapted to the through hole is provided on the left handle 4. A magnetic block 19 is slidably provided in the inner cavity of the positioning seat 10. A positioning pin 18 is fixedly provided on the bottom wall of the magnetic block 19. The positioning pin 18 is slidably connected to the through hole and adapted to the positioning hole. An electromagnet is fixedly provided on the top inner wall of the inner cavity of the positioning seat 10. The electromagnet 17 has a return spring 20 connected between the inner wall of the top of the inner cavity and the magnetic block 19. When the electromagnet 17 is energized, it attracts the magnetic block 19, causing the positioning pin 18 to move upward in the through hole, thus disengaging the positioning pin 18 from the positioning hole. This allows the left handle 4 and the left fixing bracket 5 to disengage, thereby releasing the restriction on the upper vessel body 3. The upper vessel body 3 can then be rotated outward on the right fixing bracket 5, facilitating cleaning of the upper vessel body 3. After the upper vessel body 3 is reset, the electromagnet 17 is de-energized, the return spring 20 resets the magnetic block 19, and the positioning pin 18 enters the positioning hole, thus fixing the upper vessel body 3 back in place.

[0024] Please see Figure 2Furthermore, a hydraulic cylinder 2 11 is rotatably installed between the top wall of the connecting frame 6 and the rear side wall of the upper vessel 3. With the addition of the hydraulic cylinder 2 11, the upper vessel 3 can be rotated outward more easily, so as to facilitate the cleaning of the upper vessel 3.

Multiple sets of cleaning frames 14 are fixedly arranged between the outer wall of the first sleeve 13 and the outer wall of the second sleeve 21. The edge of the cleaning frame 14 is in contact with the inner wall of the vessel body. By rotating the main shaft 22 and the second sleeve 21, the stirring rod 12 and the cleaning frame 14 can be driven to rotate relative to each other in the vessel body. The stirring rod 12 can stir the raw materials for preparing bromoacetic acid, and the cleaning frame 14 can scrape and clean the inner wall of the vessel body, which can effectively reduce the residue of materials.

[0026] Please see Figure 3 Furthermore, it also includes a drive motor 15 and a drive motor 16. The bottom wall of the operating table 1 is fixedly equipped with drive motor 15 and drive motor 16 on both sides of the rotating hole. The output end of drive motor 15 is connected to the main shaft 22 through a first pulley assembly, and the output end of drive motor 16 is connected to the sleeve 21 through a second pulley assembly. Drive motor 15 drives the main shaft 22 to rotate, and drive motor 16 drives the sleeve 21 to rotate. The rotation directions of sleeve 21 and main shaft 22 are opposite.
