Description

Technical Field

[0001] The utility model relates to the technical field of equipment, in particular to a reaction kettle for stirring methyl hydroxybutyrate. Background Art

[0002] Methyl R-3-hydroxybutyrate is a colorless liquid with a distinctive odor and is soluble in a variety of organic solvents. Its molecular formula is C5H10O3, and its molecular weight is 118.13. Also known as methyl 3-hydroxybutyrate, it is stable at room temperature and pressure, appearing as a colorless liquid with a fruity aroma. Its vapor pressure is 0.8±0.6 mmHg at 25°C, and its refractive index is 1.420. Furthermore, it is flammable and somewhat irritating to humans. From a structural perspective, methyl (R)-3-hydroxybutyrate possesses both hydroxyl and ester groups, making it a bifunctional organic building block.

[0003] Reactors are equipment frequently used in the production of chemical products. Raw materials undergo physical or chemical reactions in the reactor under a certain temperature and pressure to synthesize products. Whether the reaction can proceed fully depends largely on the contact time of different materials, and further on the uniformity of stirring. Existing reactors usually use a stirring shaft to continuously rotate in a certain direction for a certain period of time. The reactants in the reactor basically flow together as a whole with the propulsion force of the stirring paddle. The probability of mutual contact is small and the contact time is short, making it difficult to stir the materials evenly in a short time.

[0004] This case was created to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below through the accompanying drawings and examples.

[0022] like Figure 1-4 As shown: A methyl hydroxybutyrate stirring reactor, comprising a reactor body 1, a feed port 2, and a drive motor 3, characterized in that: the output end of the drive motor 3 is connected to a connecting rod 4, the end of the connecting rod 4 is connected to a main stirring roller 6, the connecting rod 4 is connected to a connecting platform 5, and the connecting rod 4 is also connected to a main rotating gear 12, the main rotating gear 12 is meshed with the first driven gear 8 and the second driven gear 9 on the left and right sides, and the lower surfaces of the first driven gear 8 and the second driven gear 9 are connected to auxiliary stirring rollers 10. The driving motor 3 drives the connecting rod 4 and the main stirring roller 6 to rotate, and at this time the main rotating gear 12 rotates accordingly, driving the first driven gear 8 and the second driven gear 9 meshed with it to rotate, and the two pairs of stirring rollers 10 also rotate synchronously therewith, so as to evenly stir the solution in the reactor.

[0023] The main stirring roller 6 is wrapped with a spiral blade 7, and the auxiliary stirring roller 10 is wrapped with a stirring rod 13 to improve the stirring efficiency.

[0024] A support platform is provided below the first driven gear 8 and the second driven gear 9. The support platform is fixedly connected to the inner wall of the reactor body 1 to support the first driven gear 8 and the second driven gear 9. A heating wire 11 is provided outside the reactor body 1 to increase the temperature during the reaction process and further accelerate the reaction speed.

[0025] A first pinion 16 and a second pinion 17 are provided directly above the first driven gear 8 and the second driven gear 9. The bottom surfaces of the first pinion 16 and the second driven gear 9 are connected to the auxiliary stirring roller 10 through a connecting rod. Furthermore, when you want to increase the stirring speed, pull up the support rod 14 to drive the connecting platform 5 tightly fitted on the outside of the connecting rod 4 to move up. The connecting rod 4 is provided with a protrusion. At this time, the connecting platform 5 moves up to the top and supports the protrusion. At this time, the second main gear 15 is engaged with the first pinion 16 and the second pinion 17. At this time, the first pinion 16 and the second pinion 17 are driven by the drive motor 3 to rotate. Since the second main gear 15 is larger than the main rotating gear 12, and the first pinion 16 and the second pinion 17 are smaller than the first driven gear 8 and the second driven gear 9, the rotation speed is faster, and the rotation speed of the two auxiliary stirring rollers 10 is also faster.

[0026] A second main gear 15 is provided directly above the main rotating gear 12. The second main gear 15 is sleeved on the outside of the connecting platform 5. The second main gear 15 is engaged with the first pinion 16 and the second driven gear 9. A support platform is provided below the main rotating gear 12, which is connected to the support platform below the first driven gear 8 and the second driven gear 9.

[0027] A support rod 14 is fixedly connected to the connecting platform 5 , and the support rod 14 passes through the top surface of the reactor body 1 .
