Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of equipment for fatty acid esterification, in particular to a fatty acid high-efficiency esterification kettle. Background Art
[0002] Fatty acid methyl ester is a widely used chemical raw material, which can be widely used in textile, metal processing, chemical industry, light industry, medicine and other industrial fields. The preparation of fatty acid methyl ester is usually based on fatty acid and methanol as raw materials, and the esterification reaction is carried out under the conditions of acid, alkali, inorganic salt and other catalysts.
[0003] The esterification reaction of fatty acids is usually completed in an esterification kettle. Since the reaction needs to be carried out under high temperature conditions and the boiling point of methanol is relatively low, during the reaction, most of the methanol is in the gas phase and accumulates in the upper part of the esterification kettle, making it difficult to fully esterify with the fatty acids. Therefore, there are often problems such as incomplete esterification reaction and low conversion rate. At present, in order to improve the conversion rate, methods such as adding excess methanol and extending the reaction time are generally adopted, but this results in high methanol consumption and low preparation efficiency.

DETAILED DESCRIPTION
[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0021] like Figure 1-4 As shown, a fatty acid efficient esterification kettle includes a reaction tank 1, a feed pipe 2 is arranged in the middle of the reaction tank 1, a control valve 1 3 is arranged on the upper part of the feed pipe 2, a control valve 2 4 is arranged in the middle of the lower side of the reaction tank 1, and an air supply mechanism 6 is arranged in the middle of the reaction tank 1.
[0022] In this embodiment, the air supply mechanism 6 includes a reduction motor 601, a transmission shaft 602, a partition 603, a limit bar 604, a plurality of one-way valve assemblies 605 and a connecting pipe 606. The upper end of the connecting pipe 606 is fixedly connected to the upper part of the reaction tank 1, one of the one-way valve assemblies 605 is peripherally installed inside the connecting pipe 606, and the lower end of the connecting pipe 606 is fixedly connected to the lower part of the reaction tank 1. The outer peripheries of the remaining one-way valve assemblies 605 are arranged on the outer side of the partition 603. The middle part of the partition 603 is threadedly connected to the upper part of the transmission shaft 602. The outer periphery of the partition 603 is slidably connected to the outer periphery of the plurality of limit bars 604. The outer sides of the plurality of limit bars 604 are fixedly connected to the inner side wall of the upper part of the reaction tank 1. The upper end of the transmission shaft 602 is rotatably connected to the inner top wall of the reaction tank 1. The reduction motor 601 is installed On the outer wall of the reaction tank 1, the lower driving end of the reduction motor 601 is fixedly connected to the upper end of the transmission shaft 602, and the one-way valve assembly 605 includes a sleeve 6051, a bracket 6052, a limit rod 6053, a sealing plate 6054, a limit disk 6055 and a spring 6056. The outer periphery of the sleeve 6051 is arranged on the outer side of the partition 603, the outer periphery of the bracket 6052 is fixedly connected to the middle part of the sleeve 6051, the outer periphery of the limit rod 6053 is slidably connected to the middle part of the bracket 6052, the middle part of the limit disk 6055 is fixedly connected to the lower end of the limit rod 6053, the spring 6056 is sleeved on the lower part of the limit rod 6053, and the spring 6056 is arranged between the bracket 6052 and the limit disk 6055, and the middle part of the sealing plate 6054 is fixedly connected to the upper end of the limit rod 6053.
[0023] Specifically, the partition 603 is now limited by the limit bar 604 so that the partition 603 cannot rotate. Therefore, when the transmission shaft 602 is driven to rotate by the reduction motor 601, the partition 603 will move up and down. When the partition 603 moves up, the one-way valve assembly 605 on the partition 603 is closed, and the one-way valve assembly 605 in the connecting pipe 606 is opened, so that the methanol on the upper part of the partition 603 enters the bottom of the reaction tank 1 through the connecting pipe 606. When the partition 603 moves down, the one-way valve assembly 605 on the partition 603 is opened, and the one-way valve assembly 605 in the connecting pipe 606 is closed, so that the methanol at the lower part of the partition 603 enters the upper part of the partition 603, and so on and so forth, so that the methanol produced by the reaction re-enters the material on the bottom wall of the reaction tank 1, and then undergoes a secondary reaction, thereby improving the utilization rate of methanol and reducing the consumption of methanol.
[0024] In this embodiment, a stirring blade 607 is slidably connected to the lower part of the transmission shaft 602. The outer periphery of the stirring blade 607 is threadedly connected to the lower part of the inner wall of the reaction tank 1. A heating wire is arranged in the middle of the side wall of the reaction tank 1. A support 5 is arranged at the lower part of the reaction tank 1.
[0025] Specifically, since the transmission shaft 602 and the stirring blade 607 can only slide, the stirring blade 607 cannot rotate relative to the transmission shaft 602. At the same time, the stirring blade 607 is threadedly connected to the lower part of the reaction tank 1. Therefore, when the transmission shaft 602 rotates, the stirring blade 607 will rotate while moving up and down, thereby fully stirring the material at the bottom of the reaction tank 1 and accelerating the reaction speed.
[0026] Working principle:
[0027] The partition 603 is now limited by the limit bar 604 so that the partition 603 cannot rotate. Therefore, when the transmission shaft 602 is driven to rotate by the reduction motor 601, the partition 603 will move up and down. When the partition 603 moves up, the one-way valve assembly 605 on the partition 603 is closed, and the one-way valve assembly 605 in the connecting pipe 606 is opened, so that the methanol on the upper part of the partition 603 enters the bottom of the reaction tank 1 through the connecting pipe 606. When the partition 603 moves down, the one-way valve assembly 605 on the partition 603 is opened, and the one-way valve assembly 605 in the connecting pipe 606 is closed. The methanol at the bottom of the partition 603 enters the top of the partition 603, and so on, so that the methanol produced by the reaction re-enters the material on the bottom wall of the reaction tank 1, and then undergoes a secondary reaction, thereby improving the utilization rate of methanol and reducing the consumption of methanol. Since the transmission shaft 602 and the stirring blade 607 can only slide, the stirring blade 607 cannot rotate relative to the transmission shaft 602. At the same time, the stirring blade 607 is threadedly connected to the lower part of the reaction tank 1. Therefore, when the transmission shaft 602 rotates, the stirring blade 607 will rotate while moving up and down, thereby fully stirring the material at the bottom of the reaction tank 1 and accelerating the reaction speed.
[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
