Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a continuous acidification vessel for fatty acids. Background Technology

[0002] Fatty acidification refers to the process of converting fatty acid salts obtained through fatty acid extraction and refining into fatty acids and their corresponding strong acid salts by adjusting the pH to acidic levels with a strong acid. Currently, acidification tanks only require mixing sulfuric acid and fatty acids before acidification, and this process takes place inside the tank.

[0003] Acidification tanks typically contain a stirring shaft, a crucial component of the tank. This shaft is connected to an electric motor via a transmission device, driving the agitator to rotate and thus achieve material mixing and agitation. However, existing acidification tanks use a single stirring shaft, with its rotation and agitation directions all pointing in the same direction. This prevents the reactants from rapidly tumbling and mixing, resulting in low agitation efficiency. Therefore, we propose a continuous fatty acid acidification tank. Utility Model Content

[0004] This invention provides a continuous acidification tank for fatty acids, which has the advantage that the reactants are driven by the impeller to flow back into the reaction tank from the discharge channel at a certain speed, thereby accelerating the reaction rate and solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A continuous acidification tank for fatty acids includes a reaction tank, with multiple support legs on the bottom side of the reaction tank, a detachable top cover on the top of the reaction tank, a stirring motor installed on the top of the top cover, a stirring device connected to the stirring motor inside the reaction tank, a discharge channel coaxially provided at the bottom of the reaction tank, a valve at the bottom of the discharge channel, and a pump casing provided on one side of the discharge channel. The top side of the pump casing has a discharge channel, and the bottom side of the pump casing has a feed channel. The end of the feed channel away from the pump casing is detachably connected to the side of the discharge channel, and the end of the discharge channel away from the pump casing is detachably connected to the side of the reaction tank. A drive shaft coaxially provided inside the pump casing has an impeller matched with the pump casing on the drive shaft. Both ends of the drive shaft are rotatably connected to the pump casing, and one end of the drive shaft is connected to the drive mechanism through a transmission mechanism.

[0006] Preferably, the top of the reaction vessel is also provided with a feeding port, and the top of the feeding port is detachably covered with a sealing cap.

[0007] Preferably, there are at least two pump casings, which are symmetrically arranged on the side of the discharge channel.

[0010] Preferably, the impeller is a helical impeller or a blade impeller.

[0011] Preferably, the drive mechanism includes a drive motor located on one side of the discharge channel. The drive motor is mounted on a motor mounting plate. Both sides of the motor mounting plate are connected to the support legs via mounting brackets. The transmission device includes a pulley mounted on the shaft of the drive motor and a pulley at one end of the drive shaft. The pulleys are connected by a belt.

[0012] Preferably, the stirring device includes a stirring shaft coaxially arranged inside the reaction vessel, the top of the stirring shaft being connected to a stirring motor, the bottom of the stirring shaft extending above the discharge channel, and a plurality of first spiral stirring blades arranged around the stirring shaft, the first spiral stirring blades being connected to the stirring shaft by a plurality of connecting rods.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1 to 5 This utility model provides a technical solution: a continuous acidification tank for fatty acids, including a reaction tank 1. The reaction tank 1 has multiple support legs 2 on its side bottom. The top of the reaction tank 1 is detachably provided with a top cover 11. The edge of the top cover 11 is fastened to the reaction tank 1 by a lock or bolt. The top of the reaction tank 1 is also provided with a feeding port 8. Reactants can be added into the reaction tank 1 through the feeding port 8. The top of the feeding port 8 is detachably provided with a sealing cover 9. The edge of the sealing cover 9 is also fastened to the feeding port 8 by a lock or bolt.

[0024] The bottom of the reaction vessel 1 is coaxially provided with a discharge channel 18, and the bottom of the discharge channel 18 is provided with a valve. When the valve is opened, the reactants in the reaction vessel 1 can be discharged.

[0025] Next, a stirring motor 10 is installed on top of the top cover 11, and a stirring device connected to the stirring motor 10 is provided inside the reaction vessel 1. For example... Figure 5As shown, the stirring device includes a stirring shaft 22 coaxially mounted inside the reaction tank 1. During installation, the top of the stirring shaft 22 is connected to the stirring motor 10, and the stirring shaft 22 is rotatably connected to the top cover 11. The bottom of the stirring shaft 22 extends above the discharge channel 18. Multiple first spiral stirring blades 19 are provided around the stirring shaft 22, and each first spiral stirring blade 19 is connected to the stirring shaft 22 via multiple connecting rods 21. When the stirring motor 10 rotates, it drives the stirring shaft 22 to rotate, which in turn drives the first spiral stirring blades 19 to rotate, thus stirring the reactants inside the reaction tank 1.

[0026] To increase the tumbling of the reactants, multiple second spiral stirring blades 20 are provided around the stirring shaft 22. The second spiral stirring blades 20 are located between the first spiral stirring blade 19 and the stirring shaft 22, and the second spiral stirring blades 20 and the first spiral stirring blade 19 rotate in opposite directions. The second spiral stirring blades 20 are mounted on the connecting rod 21, so that the second spiral stirring blades 20 and the first spiral stirring blade 19 can stir the reactants simultaneously, causing the reactants to tumble in different directions and increasing the mixing efficiency of the reactants.

[0027] The most important aspect of this application is that a pump casing 7 is provided on one side of the discharge channel 18. In actual production, the number of pump casings 7 is at least two, and they are symmetrically arranged on the side of the discharge channel 18. Figure 3 and Figure 4 As shown, a discharge channel 16 is provided on the top side of the pump casing 7, and a feed channel 17 is installed on the bottom side of the pump casing 7. The end of the feed channel 17 away from the pump casing 7 is detachably connected to the side of the discharge channel 18, and the end of the discharge channel 16 away from the pump casing 7 is detachably connected to the side of the reaction tank 1. Specifically, flanges are provided at the end of the feed channel 17 away from the pump casing 7 and at the end of the discharge channel 16 away from the pump casing 7, so that the flanges are fastened to the side of the discharge channel 18 and the side of the reaction tank 1 by bolts.

[0028] A drive shaft 4 is coaxially mounted inside the pump casing 7. An impeller, either helical or blade-type, is mounted on the drive shaft 4 and matches the pump casing 7. Both ends of the drive shaft 4 are rotatably connected to the pump casing 7, and one end of the drive shaft 4 is connected to the drive mechanism via a transmission mechanism. When the drive shaft 4 rotates, it drives the impeller to rotate within the pump casing 7. Figure 4In the direction indicated by the middle arrow, the reactants in the reaction tank 1 flow into the discharge channel 18. The reactants in the discharge channel 18 are sucked in by the feed channel 17, and then the reactants are driven by the impeller to flow back into the reaction tank 1 from the discharge channel 16. Because the impeller drives the flow of reactants, the reactants can flow at a certain speed, causing the reactants flowing into the reaction tank 1 to collide with the first spiral stirring blade 19 and the second spiral stirring blade 20 at a certain speed. This causes the first spiral stirring blade 19 and the second spiral stirring blade 20 to stir the reactants flowing from the direction of the discharge channel 16, thereby increasing the reaction rate.

[0029] Furthermore, the side of the pump casing 7 is connected to the support leg 2 via a reinforcing frame 3, thereby increasing the stability of the pump casing 7. End caps 5 are detachably installed at both ends of the pump casing 7, with the edges of the end caps 5 fastened to the pump casing 7 by bolts. Both ends of the drive shaft 4 are rotatably connected to the end caps 5, and a sealing assembly is provided between them. The drive shaft 4 and the end caps 5 are connected by bearings, and the sealing assembly is a shaft seal installed inside the end caps 5 to seal the drive shaft 4.

[0030] Furthermore, the drive mechanism includes a drive motor 13 located on one side of the discharge channel. The drive motor 13 is mounted on a motor mounting plate 15, and both sides of the motor mounting plate 15 are connected to the support legs 2 via mounting brackets 6.

[0031] The transmission device includes a pulley 12 mounted on the shaft of the drive motor 13 and at one end of the drive shaft 4, with the pulleys 12 connected by a belt. To increase the stability of the drive motor 13, such as... Figure 1 As shown, a reinforcing rod 23 is provided between the support legs 2 connected to the mounting bracket 6, and a reinforcing seat 14 supporting the ground is also provided at the bottom of the motor mounting plate 15.

[0032] Based on the above embodiments, further optimization can be achieved by designing the bottom of the reaction vessel 1 as a conical or circular structure, so that the reactants can flow in the opposite direction to the discharge channel 18 by their own gravity.

[0033] Based on the above embodiments, further optimizations can be made, such as... Figure 3 and Figure 4 As shown, the feed channel 17 is inclined downwards, while the discharge channel 16 is inclined upwards. This allows the feed channel 17, the discharge channel 16, and the pump casing to automatically flow downwards during discharge and exit through the discharge channel 18.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
