Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a reaction vessel for chitosan production and processing. Background Technology

[0002] Chitosan, also known as deacetylated chitin, requires various ingredients to be added to a reaction vessel in specific proportions for processing during its production. In related technologies, to improve enzymatic hydrolysis efficiency, most existing reaction vessels rely on a single stirring rod to agitate the reactants. However, this method struggles to achieve rapid reactions, and when the amount of reactants is large, not only is agitation difficult but also time-consuming, increasing production time and reducing overall efficiency. Therefore, we propose a reaction vessel for chitosan production and processing. Utility Model Content

[0003] This invention provides a reaction vessel for chitosan production and processing, which has the advantages of multiple stirring shafts and accelerated reaction flow, thus solving the problems mentioned in the background art.

[0004] The technical solution of this utility model is implemented as follows: A reaction vessel for chitosan production and processing is designed, including a vessel body with a detachable lid on the top. A third stirring shaft is rotatably mounted at the center of the lid, and a stirring device is mounted on its surface. A dual-shaft drive device is coaxially mounted on the top of the lid and connected to the top of the third stirring shaft. A second stirring shaft and a first stirring shaft are arranged around the third stirring shaft. Both the first and second stirring shafts are rotatably connected to the lid, and the first stirring shaft is inclined. A dispersing device is mounted on the second and first stirring shafts. The top of the first stirring shaft is connected to a connecting shaft through a universal joint. The connecting shaft is parallel to the central axis of the vessel body and rotatably mounted in a support frame. The tops of the connecting shaft and the second stirring shaft are connected to the top of the dual-shaft drive device through a transmission device.

[0005] Preferably, the stirring device is a stirring blade mounted on the surface of a third stirring shaft.

[0006] Preferably, the dispersing device is a dispersing disc or a stirring plate installed on the first stirring shaft and the second stirring shaft.

[0007] Preferably, the bottom edge of the vessel body is provided with multiple support legs, and the bottom of the vessel body is provided with a discharge valve.

[0008] Preferably, the top of the support cover is provided with a feeding port, and the top of the feeding port is detachably provided with a sealing cap.

[0009] Preferably, the bottom of the third stirring shaft is provided with an arc-shaped stirring rod, the shape of which is consistent with the shape of the bottom of the vessel.

[0010] Preferably, the dual-shaft drive device includes a support cover coaxially mounted on the top of the vessel lid, an annular seat coaxially provided on the top of the support cover, a dual-shaft motor mounted on the top of the annular seat, and the bottom of the dual-shaft motor connected to the top of the third stirring shaft.

[0011] Preferably, the transmission device includes pulleys respectively disposed on the top of the dual-shaft motor and on the top of the connecting shaft and the second stirring shaft, and the pulleys are connected by a belt.

[0012] Preferably, the support frame includes a first bearing seat, which is rotatably connected to the connecting shaft, and the first bearing seat is fixed to the edge of the annular seat or the top of the vessel lid by a first support.

[0021] 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.

[0022] Reference Figures 1 to 4 This utility model provides a technical solution: a reaction vessel for chitosan production and processing, including a vessel body 1. Multiple support legs 15 are provided at the bottom edge of the vessel body 1. A detachable lid 12 is provided at the top of the vessel body 1. The edge of the lid 12 is connected to the top edge of the vessel body 1 by a latch or bolt. Chitosan is processed inside the vessel body 1. In use, the reactants are poured in through a feeding port 11 located at the top of the support cover 2. The top of the feeding port 11 is sealed by a detachable sealing cap, and the two are connected by a latch. After the reactants have reacted inside the vessel body 1, the reactants can be discharged from the discharge valve 14 at the bottom of the vessel body 1.

[0023] like Figure 3 As shown, a third stirring shaft 18 is rotatably provided at the center of the lid 12. The third stirring shaft 18 is placed inside the body 1. A stirring device is provided on the surface of the third stirring shaft 18. The stirring device is a stirring blade 20 installed on the surface of the third stirring shaft 18. There are multiple stirring blades 20, and each stirring blade 20 is inclined. When the third stirring shaft 18 rotates, it can drive multiple stirring blades 20 to rotate at the same time. In order for the third stirring shaft 18 to agitate the sediment at the bottom of the vessel body 1, such as Figure 3 and Figure 4 As shown, an arc-shaped stirring rod 21 is provided at the bottom of the third stirring shaft 18. The shape of the arc-shaped stirring rod 21 is consistent with the shape of the bottom of the vessel body 1. There is at least one arc-shaped stirring rod 21. Both the arc-shaped stirring rod 21 and the bottom of the vessel body 1 are arc-shaped structures and are fitted with a gap between them. The arc-shaped stirring rod 21 is also inclined, so that the sediment at the bottom of the vessel body 1 can be stirred by the arc-shaped stirring rod 21.

[0024] Furthermore, the stirring speed of a single third stirring shaft 18 is limited. To increase the stirring force, such as... Figure 3 and Figure 4 As shown, a second stirring shaft 10 and a first stirring shaft 3 are arranged around the third stirring shaft 18. There is at least one second stirring shaft 10 and one first stirring shaft 3. Both the first stirring shaft 3 and the second stirring shaft 10 are rotatably connected to the vessel cover 12. The first stirring shaft 3 and the second stirring shaft 10 are both placed inside the vessel body 1. The second stirring shaft 10 is parallel to the third stirring shaft 18, but the first stirring shaft 3 is inclined, meaning that the first stirring shaft 3 and the third stirring shaft 18 are not parallel. Instead, the first stirring shaft 3 is inserted obliquely from the top of the support cover 2 into the interior of the vessel body 1. Dispersion devices are provided on the second stirring shaft 10 and the first stirring shaft 3. These dispersion devices are dispersion discs 17 or stirring blades (hereinafter referred to as dispersion discs 17) installed on the first stirring shaft 3 and the second stirring shaft 10. There are more than one stirring blade and dispersion disc 17, and they are arranged in layers on the first stirring shaft 3 and the second stirring shaft 10. In actual use, the first stirring shaft 3, the second stirring shaft 10, and the third stirring shaft 18 rotate simultaneously. The dispersion disc 17 is also called a stirring disc, so the dispersion disc 17 and the stirring blades 20 simultaneously agitate the reactants. The dispersion disc 17 and the stirring blades 20 can be made to stir in opposite directions, which can accelerate the flow rate of the reactants. It should be emphasized that the first stirring shaft 3 is tilted to accelerate the flow of the reactants, such as... Figure 4 As indicated by the middle arrow A, when the dispersion disk 17 on the first stirring shaft 3 rotates, the direction of the reactant flow it carries forms an angle with the direction of the reactant flow stirred by the second stirring shaft 10 and the third stirring shaft 18. Therefore, the flow direction of the reactants in the vessel body 1 will be chaotic and turbulent under the action of multiple dispersion disks and stirring blades, thus allowing the reactants to react rapidly. It should also be noted that... Figure 4 Arrows A and B in the diagram are for illustrative purposes only. In actual use, the direction in which the dispersion disk 17 drives the flow of reactants is dispersed and cannot be truly represented.

[0025] Based on the above embodiments, such as Figure 1 and Figure 2 As shown, a dual-shaft drive device is coaxially mounted on the top of the vessel lid 12 and connected to the top of the third stirring shaft 18. The dual-shaft drive device includes a support cover 2 coaxially mounted on the top of the vessel lid 12, and the bottom of the support cover 2 is fastened to the vessel lid 12 by bolts. An annular seat 4 is coaxially mounted on the top of the support cover 2, and a dual-shaft motor 16 is mounted on the top of the annular seat 4. The two are also fixed by bolts. During installation, the bottom of the dual-shaft motor 16 is connected to the top of the third stirring shaft 18, so that when the dual-shaft motor 16 rotates, it can drive the third stirring shaft 18 to rotate. It should be noted that, due to the special inclined setting of the first stirring shaft 3, the top of the first stirring shaft 3 is connected to the connecting shaft 8 through the universal joint 5. The connecting shaft 8 is parallel to the central axis of the vessel body 1 and is rotatably installed in the support frame. The support frame includes a first bearing seat 7, which is rotatably connected to the connecting shaft 8. The first bearing seat 7 is fixed to the edge of the annular seat 4 or the top of the vessel cover 12 by the first support 6. Figures 1 to 4 The first support 6 is set on the annular seat 4 (the connection between the first support 6 and the lid 12 is not shown in the figure), so that the connecting shaft 8 can be fixed. In order to make the first stirring shaft 3, the second stirring shaft 10 and the third stirring shaft 18 rotate simultaneously, the top of the connecting shaft 8 and the top of the second stirring shaft 10 are connected to the top of the dual-shaft drive device through a transmission device. The transmission device includes pulleys 9 respectively set on the top of the dual-shaft motor 16 and the top of the connecting shaft 8 and the second stirring shaft 10. The pulleys 9 are connected by a belt, so when the dual-shaft motor rotates, it can drive the first stirring shaft 3, the second stirring shaft 10 and the third stirring shaft 18 to rotate simultaneously. In practical use, the transmission ratio can also be changed by changing the diameter of the pulley 9, that is, making the diameter of the pulley on the dual-shaft motor larger than the diameter of the other pulleys, so that the large pulley drives the small pulley to rotate, making the second stirring shaft 10 and the first stirring shaft 3 rotate faster.

[0026] Based on the above embodiments, further optimizations can be made to increase the strength of the top of the second stirring shaft 10, such as... Figure 1 and Figure 2 As shown, the top of the second stirring shaft 10 is rotatably mounted in the second bearing seat 19, and the second bearing seat 19 is fixed to the edge of the annular seat 4 or the top of the lid 12 by the second support 22. Figures 1 to 4 The second support 22 is set on the annular seat 4. The connection between the second support 22 and the lid 12 is not shown in the figure.

[0027] Based on the above embodiments, further optimization is possible. The top of the vessel lid 12 is provided with multiple mounting ports 13. The top of the mounting port 13 is detachably provided with a cover plate. The mounting port 13 is used to install level gauges, temperature sensors, steam sterilization tubes, etc. When the mounting port 13 is not in use, it can be sealed with a cover plate.

[0028] 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.
