Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, specifically relating to a reaction vessel for the production of methyl ethyl ketone. Background Technology

[0002] Methyl ethyl ketone is a ketone organic compound, a colorless and transparent liquid with an acetone-like odor. It is volatile and miscible with ethanol, ether, benzene, chloroform, and oils. It can be used as a solvent in paints and inks, as well as an intermediate in dyes, detergents, fragrances, antioxidants, and certain catalysts, and as an analytical reagent. The production of methyl ethyl ketone requires a reaction vessel, which is the site where the different materials react during the process. The main structure of the reaction vessel includes the vessel shell, a stirring mechanism, and a feed inlet. The stirring mechanism includes a drive motor, a rotating shaft, and stirring blades, which mix the materials inside the reaction vessel and facilitate the reaction.

[0003] When the stirring blades inside the reactor are stirring the materials for the production of methyl ethyl ketone, the stirring shaft will be subjected to the impact of the materials during long-term high-speed rotation, which may cause deformation and even breakage, affecting the stirring process. The reactor does not have a design to reinforce the stirring shaft, which is a shortcoming.

[0004] Existing reactors lack a reinforced design to strengthen the stirring shaft. To address this, this application proposes a reactor for the production of methyl ethyl ketone. Utility Model Content

[0027] 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.

[0028] Please see Figures 1 to 5This utility model provides a technical solution: a reaction vessel for the production of methyl ethyl ketone, comprising a reaction vessel device including a support frame 1, a vessel body, and a drive mechanism. The vessel body includes a vessel body 21, a ramp portion 22, and a concentrating cone portion 23. The drive mechanism includes a drive motor 31, a drive shaft 32, a first stirring blade 33, and a second stirring blade 34. The support frame 1 supports the vessel body, that is, the support frame 1 supports the vessel body 21, the ramp portion 22, and the concentrating cone portion 23. The vessel body is composed of the vessel body 21, the ramp portion 22, and the concentrating cone portion 23. The ramp portion 22 and the concentrating cone portion 23 at the bottom of the vessel body have a gradually narrowing structure, and the lower end of the vessel body has a reduced volume structure, which is conducive to the material settling at the bottom and avoids the material settling near the inner wall of the vessel body, which would lead to uneven stirring. The limiting components include a partition 51 installed inside the vessel body 21, a connecting column 52 of the vertical partition 51, and a limiting ring 5 fixedly connected to the bottom end of the connecting column 52. 3. The limiting ring 53 serves to limit the reinforcing crossbar 71, preventing it from tilting in the vertical direction. The reinforcing rotating cylinder 6 is installed inside the vessel body 21 and sleeved on the outside of the drive shaft 32. The reinforcing rotating cylinder 6 is fixed to the drive shaft 32 by bolts and rotates in the same direction as the drive shaft 32. The reinforcing rotating cylinder 6 increases the strength of the drive shaft 32 and reduces the impact force on the drive shaft 32. The reinforcing assembly includes a reinforcing crossbar 71 perpendicular to the reinforcing rotating cylinder 6, a scraper 72 whose top end is fixedly connected to the end of the reinforcing crossbar 71, a reinforcing rib 73 installed between the reinforcing rotating cylinder 6 and the scraper 72, and a stirring blade 74 installed on the outside of the reinforcing rib 73. The reinforcing crossbar 71, the scraper 72, and the reinforcing rib 73 form a reinforcing bracket to reduce the impact force on the drive shaft 32. As the reinforcing rotating cylinder 6 rotates, the stirring blade 74 agitates the material close to the inner wall of the vessel body 21.

[0029] In this embodiment, the center lines of the drive shaft 32, the reinforcing rotating cylinder 6, and the partition 51 are on the same vertical axis. The reinforcing rotating cylinder 6 and the partition 51 are rotatably connected by bearings, and the reinforcing rotating cylinder 6 and the drive shaft 32 are fixedly connected by bolts. The reinforcing rotating cylinder 6 increases the strength of the drive shaft 32 and reduces the impact force on the drive shaft 32.

[0030] In this embodiment, the reinforcing crossbar 71 is tangent to the limiting ring 53, and the connecting column 52 is perpendicular to the reinforcing crossbar 71. The friction between the reinforcing crossbar 71 and the limiting ring 53 is small and does not affect the rotation of the reinforcing crossbar 71.

[0031] In this embodiment, the scraper 72 includes a vertical part a, a first inclined part b, and a second inclined part c. The vertical part a is attached to the inner wall of the vessel body 21, the first inclined part b is attached to the inner wall of the slope part 22, and the second inclined part c is attached to the inner wall of the concentrating cone part 23. As the reinforcing crossbar 71 rotates, the scraper 72 scrapes the material close to the inner wall of the vessel body 21.

[0032] In this embodiment, the stirring spaces inside the vessel body 21, the inclined section 22, and the concentrating cone section 23 are, from top to bottom, a mixing zone, a stirring zone B, and a sedimentation zone C. The material settles in the stirring zone B and the sedimentation zone C. The stirring zone B and the sedimentation zone C are narrow spaces with gradually decreasing space, which is conducive to the sedimentation of the material and also conducive to the stirring of the sedimented material by the first stirring blade 33 and the second stirring blade 34.

[0033] In this embodiment, a circulation conveying assembly is provided on the support frame 1 and the vessel body 21. The circulation conveying assembly includes a circulation pump 4 fixedly connected to the support frame 1 and a diversion ring pipe 9 installed inside the vessel body 21. The circulation pump 4 is connected to the concentrating cone 23 and the diversion ring pipe 9 through pipes. The diversion ring pipe 9 is provided with uniformly distributed nozzle pipes 91. The material settles in the stirring zone B and the sedimentation zone C. The circulation pump 4 runs, sucks up the settled material, and conveys it to the diversion ring pipe 9 and sprays it out from the nozzle pipes 91, so as to achieve the function of circulating and discharging the settled material. The settled material is then stirred again by the first stirring blade 33 and the second stirring blade 34. A stabilizing column 8 is provided between the diversion ring pipe 9 and the connecting column 52 to enhance the stability of the diversion ring pipe 9 and the connecting column 52. A shield 10 is fixedly connected to the inner wall of the vessel body 21 to prevent the material sprayed from the nozzle pipes 91 from spraying towards the inner wall of the vessel body 21.

[0034] Working principle and usage process of this utility model:

[0035] The reactor of this application consists of a vessel body 21, a ramp portion 22, and a concentrating cone portion 23. The ramp portion 22 and the concentrating cone portion 23 at the bottom of the vessel body have a gradually narrowing structure. The lower end of the vessel body has a reduced volume structure, which is conducive to the material settling at the bottom and avoids the material settling near the inner wall of the vessel body, which would lead to uneven stirring.

[0036] The material settles in the mixing zone B and settling zone C formed by the inclined section 22 and the concentrated cone section 23. The inclined section 22 and the concentrated cone section 23 are narrow spaces with gradually decreasing space, which is conducive to the settling of the material and also conducive to the stirring of the settled material by the first stirring blade 33 and the second stirring blade 34.

[0037] When the circulating pump 4 is running, it draws in the settled material and transports it to the diversion ring pipe 9, where it is sprayed out from the nozzle pipe 91, thus achieving the function of circulating and discharging the settled material, so that the settled material is stirred again by the first stirring blade 33 and the second stirring blade 34.

[0038] The reinforcing rotating cylinder 6 is fixed to the drive shaft 32 by bolts. The reinforcing rotating cylinder 6 and the drive shaft 32 rotate in the same direction. The reinforcing rotating cylinder 6 increases the strength of the drive shaft 32 and reduces the impact force on the drive shaft 32.

[0039] The reinforcing crossbar 71, scraper 72, and reinforcing rib 73 form a reinforcing bracket to reduce the impact force on the drive shaft 32;

[0040] As the rotating drum 6 rotates, the stirring blades 74 also agitate the material near the inner wall of the vessel body 21, thus playing a role in stirring the material.

[0041] In summary: the slope 22 and the concentrating cone 23 at the bottom of the vessel body are gradually narrowed structures, and the lower end of the vessel body has a reduced volume structure, which is conducive to the sedimentation of materials at the bottom. The reactor has a reinforced design for the drive shaft 32, and the reinforced rotating cylinder 6 is sleeved on the outside of the drive shaft 32. The reinforcing crossbar 71, scraper 72 and reinforcing rib 73 form a reinforcing support to reduce the impact force on the drive shaft 32. As the reinforced rotating cylinder 6 rotates, the stirring blades 74 also agitate the materials near the inner wall of the vessel body 21, which also plays a role in stirring the materials.

[0042] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
