Description

Technical Field

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

[0002] Stigmasterol monomer is an optically active white solid, a type of phytosterol. Its relative density is slightly greater than water, its melting point is above 100℃, and it is insoluble in water, alkalis, and acids, but slightly soluble in acetone and ethanol at room temperature. Stigmasterol monomer has important physiological activities in the human body and is an important raw material for the production of steroidal drugs and vitamin D3; it is also used as an anti-inflammatory drug. The dehydrogenation reaction apparatus used in the production of stigmasterol monomer is typically used in chemical production and requires a catalyst to promote the reaction. It is a chemical reaction that removes hydrogen atoms from the stigmasterol molecule. During the reaction, stigmasterol needs to be prepared as a raw material, along with the necessary catalyst and auxiliary materials.

[0003] In existing dehydrogenation reactors for the production of monomeric stigmasterol, the pre-mixed stigmasterol raw material and catalyst are manually poured into the reactor through feed hoppers at the top. The stirring structure then mixes the stigmasterol raw material and catalyst. However, the stigmasterol raw material and catalyst are often poured into the reactor all at once, making it difficult to fully and evenly mix the various materials in a short time. This results in low efficiency and unevenness during the stirring reaction, affecting the overall processing efficiency. Furthermore, blockages are prone to occur during discharge, affecting the discharge efficiency.

[0004] Therefore, a reaction vessel for the production of monomeric stigmasterol is needed to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a reaction vessel for the production of monomeric stigmasterol, so as to solve the problems mentioned in the background art.

[0007] It should be noted in the solution that the intermittent component includes an end plate fixed to the top of the stirring shaft. The end plate is fitted to the inner wall of the top of the reactor. A sealing rubber gasket is provided between the end plate and the inner wall of the reactor. A discharge port connected to the discharge port is provided on the side of the end plate. Multiple discharge ports are provided and multiple discharge ports are corresponding to multiple discharge ports.

[0008] It is worth noting that the auxiliary discharge assembly includes an agitator a fixed to the bottom end of the agitator shaft, and an agitator b fixed to the agitator a.

[0009] Furthermore, it should be noted that there are multiple stirring rods b, and the multiple stirring rods b are distributed at equal intervals.

[0010] In a preferred embodiment, an exhaust pipe communicating with the interior of the reactor is fixed on the outer wall of the reactor, and valves are installed on both the exhaust pipe and the discharge pipe.

[0011] In a preferred embodiment, the bottom of the reactor is fixed with support rods, and multiple support rods are provided and the multiple support rods are symmetrically distributed.

[0012] Compared with the prior art, the reaction vessel for producing monomeric stigmasterol provided by this utility model has at least the following beneficial effects:

[0013] (1) During the rotation of the stirring shaft, the stirring shaft drives the intermittent opening component to open multiple feed ports intermittently, so that multiple material buckets can intermittently feed raw materials into the reactor, effectively improving the uniform mixing efficiency of materials, improving the overall mixing dehydrogenation reaction efficiency, and improving the overall processing quality.

[0014] (2) After the material inside the reactor is mixed and dehydrogenated, the valve on the discharge pipe is opened and the material is discharged through the discharge pipe.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Please see Figure 1-4This utility model provides a reaction vessel for the production of monomeric stigmasterol, including a reaction vessel 3. A discharge port 12 communicating with the reaction vessel 3 is provided on the top side wall. Multiple discharge ports 12 are arranged in a ring, and a material container 5 is fixed inside each discharge port 12. A drive motor 9 is fixed on the top side of the reaction vessel 3. A stirring shaft 10 is rotatably connected to the center of the top side wall of the reaction vessel 3. The output end of the drive motor 9 is fixed to one end of the stirring shaft 10. The top of the stirring shaft 10 is provided with a discharge port. The intermittently opening and closing assembly 1 has multiple ring-shaped blades 11 fixed on the side of the stirring shaft 10. A discharge pipe 7 connected to the interior of the reactor 3 is fixed to the bottom of the reactor 3. An electric heating plate is installed at the bottom of the reactor 3. An auxiliary discharge assembly 2 is provided at the bottom of the stirring shaft 10. In use, the prepared stigmasterol raw material and corresponding catalyst auxiliary materials are poured into multiple material containers 5. The drive motor 9 is started, and the output of the drive motor 9 drives the stirring shaft 10 to... The rotating shaft 10 drives multiple blades 11 to stir the materials inside the reactor 3 evenly. The reactor 3 is heated by an electric heating plate, facilitating the mixing and dehydrogenation reaction. During the rotation of the shaft 10, the intermittent opening assembly 1 opens multiple feed ports 12, allowing multiple feed tanks 5 to intermittently feed raw materials into the reactor 3. This effectively improves the uniform mixing efficiency, enhances the overall mixing and dehydrogenation reaction efficiency, and improves the overall processing quality. After the dehydrogenation reaction of the materials inside the reactor 3 is completed, the valve on the discharge pipe 7 is opened, and the materials are discharged through the discharge pipe 7. At the same time, the drive motor 9 drives the stirring shaft 10 to continue rotating, thereby driving the blades 11 to continue stirring the materials inside the reactor 3 through the stirring shaft 10. At the same time, the auxiliary discharge assembly 2 drives the auxiliary discharge assembly 2 to stir the materials at the bottom of the reactor 3 in multiple positions, improving the flow effect of the materials at the bottom of the reactor 3, assisting the materials in the discharge pipe 7 to be discharged smoothly, reducing the risk of material blockage, and improving the discharge efficiency.

[0022] Further as Figure 2 and Figure 4As shown, it is worth noting that the intermittent opening component 1 includes an end plate 101 fixed to the top of the stirring shaft 10. The end plate 101 is fitted against the inner wall of the top of the reactor 3. A sealing rubber gasket is provided between the end plate 101 and the inner wall of the reactor 3. A discharge port 102 connected to the discharge port 12 is opened on the side of the end plate 101. Multiple discharge ports 102 are provided, and multiple discharge ports 102 are corresponding to multiple discharge ports 12. In specific operation, during the rotation of the stirring shaft 10, the stirring shaft 10 drives the end plate 101 to rotate, so that the discharge ports 102 and the discharge ports 12 intermittently overlap, realizing the intermittent opening of multiple discharge ports 12. This allows multiple material tanks 5 to intermittently feed raw materials into the reactor 3, effectively improving the uniform mixing efficiency of materials, improving the overall mixing and dehydrogenation reaction efficiency, and improving the overall processing quality.

[0023] Further as Figure 2 and Figure 4 As shown, it is worth noting that the auxiliary discharge assembly 2 includes an agitation connecting rod a201 fixed to the bottom end of the agitation shaft 10, and an agitation connecting rod b202 fixed on the agitation connecting rod a201. In actual operation, the rotating agitation shaft 10 drives the agitation connecting rod a201 to rotate synchronously, thereby agitating the material at the bottom of the reactor 3 at multiple positions through the agitation connecting rod a201 and the agitation connecting rod b202, improving the material flow effect at the bottom of the reactor 3, assisting the material in the discharge pipe 7 to be discharged smoothly, reducing the risk of material blockage, and improving the discharge efficiency.

[0024] This solution includes the following working process: The prepared stigmasterol raw material and corresponding catalyst auxiliary materials are poured into multiple material tanks 5. The drive motor 9 is started, and its output drives the stirring shaft 10 to rotate. This, in turn, drives multiple blades 11 to stir the materials inside the reactor 3 evenly. During the rotation of the stirring shaft 10, the end plate 101 rotates, causing the discharge port 102 and discharge outlet 12 to intermittently overlap, thus intermittently opening the multiple discharge ports 12. Multiple material tanks 5 can intermittently feed raw materials into the reactor 3, causing the materials inside the reactor 3 to be stirred, mixed, and undergo dehydrogenation. After the dehydrogenation reaction is completed, the valve on the discharge pipe 7 is opened, and the material is discharged through the discharge pipe 7. At the same time, the drive motor 9 drives the stirring shaft 10 to continue rotating. The rotating stirring shaft 10 drives the stirring connecting rod a201 to rotate synchronously. Thus, the stirring connecting rod a201 and the stirring connecting rod b202 stir the material at the bottom of the reactor 3 in multiple positions, assisting the material to be discharged smoothly through the discharge pipe 7.

[0025] Further as Figure 4As shown, it is worth noting that there are multiple stirring rods b202, which are equidistantly distributed. In actual operation, the multiple stirring rods b202 further enhance the stirring effect on the material at the bottom of the reactor 3.

[0026] Further as Figure 1 As shown, it is worth noting that an exhaust pipe 4, which communicates with the interior of the reactor 3, is fixed on the outer wall of the reactor 3. Both the exhaust pipe 4 and the discharge pipe 7 are equipped with valves 6. During operation, excess gas inside the reactor 3 can be discharged through the exhaust pipe 4.

[0027] Further as Figure 1 and Figure 2 As shown, it is worth noting that the bottom of the reactor 3 is fixed with a support rod 8, and there are multiple support rods 8, which are symmetrically distributed.

[0028] In summary: By driving the agitator shaft 10 to intermittently open multiple feed ports 12 via the intermittent opening assembly 1, multiple feed tanks 5 can intermittently feed raw materials into the reactor 3, effectively improving the uniform mixing efficiency of materials, the overall mixing and dehydrogenation reaction efficiency, and the overall processing quality. After the mixing and dehydrogenation reaction of materials inside the reactor 3 is completed, the valve on the discharge pipe 7 is opened, and the material is discharged through the discharge pipe 7. At the same time, the drive motor 9 drives the agitator shaft 10 to continue rotating, thereby driving the blades 11 to continue agitating the materials inside the reactor 3. Simultaneously, the agitator shaft 10 drives the auxiliary discharge assembly 2 to agitate the materials at the bottom of the reactor 3 at multiple positions, improving the material flow effect at the bottom of the reactor 3, assisting the smooth discharge of materials through the discharge pipe 7, reducing the risk of material blockage, and improving the discharge efficiency.

[0029] The drive motor 9 can be purchased from the market. The drive motor 9 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
