Description

Technical Field

[0001] This utility model belongs to the field of biochemical technology, specifically relating to a reaction vessel for preparing biochemical products. Background Technology

[0002] Biochemical product preparation reactors are closed containers designed for biological and chemical synthesis processes. They achieve high-efficiency production through precise control of reaction conditions. Their core principle lies in using a stirring device to promote material mixing and ensure the homogeneity of the reaction system. These reactors integrate reaction site, condition control, and process optimization, significantly improving reaction selectivity and conversion rates. In application areas, they cover the entire biopharmaceutical chain, such as antibiotic fermentation, vaccine culture, and protein purification; in the food industry, they are used for fermenting seasonings, enzymatically hydrolyzing oils, and synthesizing additives; and in the energy sector, they support biodiesel production and biomass conversion. Their flexible adaptability to intermittent small-batch production and continuous large-scale manufacturing has made them key equipment driving the transformation of the biochemical industry from laboratory research to industrialization.

[0003] Chinese Patent Publication No. CN222943480U discloses a reaction vessel for preparing biochemical products, belonging to the field of biochemical product preparation technology. It includes a processing tank with a fixed block fixedly connected to its surface. An electric push rod is mounted on the top of the fixed block, and a top plate is mounted on the top of the electric push rod. A sleeve is installed inside the top plate, and a rotating shaft is fitted inside the sleeve. A first driven gear is fixedly connected to the top of the rotating shaft. The advantages of this reaction vessel for preparing biochemical products are that, through the operation of the electric push rod, the top plate can be raised and lowered, facilitating the inspection and repair of the processing tank and its structure. Through the operation of the first drive assembly, the first driven gear, the rotating shaft, and the stirring blade can be rotated, causing the material inside the processing tank to flow and slosh, thus performing stirring treatment. By setting a sliding groove, the slider can be limited and supported, ensuring the stability of the slider during rotation.

[0004] In practical use, this utility model is usually equipped with a special cleaning component to improve cleaning efficiency. However, existing biochemical product preparation reactors generally suffer from a lack of structural simplicity. Most rely on only a few basic scrapers to mechanically peel off the adhering substances on the inner wall. When faced with stubborn residues such as high-viscosity polymers, biocolloids, or inorganic salt scale, this traditional cleaning mode often fails to achieve thorough cleaning of the inner wall due to factors such as uneven contact pressure distribution and limited effective area. The continuous accumulation of residual materials not only reduces the cleanliness index of the reactor but may also affect the product quality of subsequent production batches through cross-contamination, making the practicality of biochemical product preparation reactors somewhat lacking. Utility Model Content

[0005] This invention proposes a reaction vessel for the preparation of biochemical products to solve the problem of the difficulty in thoroughly cleaning the material adhering to the inner wall of the reaction vessel in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reaction vessel for preparing biochemical products, comprising:

[0007] The reactor body and top cover;

[0008] A drive shaft is rotatably connected to the bottom end of the top cover plate.

Multiple stirring blades are provided on the outside of both the drive shaft and the installation sleeve, and multiple support rods are provided on the outside of the installation sleeve.

[0009] Multiple scrapers are pressed against the inner wall of the reactor body. Multiple support rods located on the same side are provided with the same "U"-shaped mounting frame. Each of the multiple mounting frames is provided with a mounting plate. The multiple scrapers are located on one side of the multiple mounting plates respectively.

[0010] An annular plate is provided at the bottom of the top cover plate. A fixing ring is provided on the outer side of the upper end of the mounting sleeve. A feed inlet is provided on one side of the upper end of the top cover plate. A discharge outlet is provided at the bottom end of the reactor body.

[0011] To improve the cleaning effect on the inner wall of the reactor, multiple positioning rods are provided on one side of each of the multiple scrapers, and positioning holes adapted to the positioning rods are opened on one side of each of the multiple mounting plates. The multiple positioning rods are respectively located in the multiple positioning holes and are each provided with a limiting spring. The other end of the multiple limiting springs is respectively set on one side of the multiple positioning holes.

[0012] In a preferred embodiment, the bottom end of the annular plate is provided with a plurality of first abutting blocks, and the upper end of the fixing ring is provided with a plurality of second abutting blocks. The plurality of first abutting blocks and the plurality of second abutting blocks are all arranged in a hemispherical shape, and the plurality of first abutting blocks abut against the upper end of the plurality of second abutting blocks.

[0013] In a preferred embodiment, a positioning shaft is provided through one side of the top cover plate, and pulleys are provided on the outer sides of both the drive shaft and the positioning shaft. The two pulleys are provided with the same transmission belt. A positioning wheel is provided on the outer side of the positioning shaft. An external toothed ring that meshes with the positioning wheel is provided on the outer side of the annular plate. A drive motor is provided at the upper end of the top cover plate, and the upper end of the drive shaft is located at the output end of the drive motor.

[0014] In a preferred embodiment, the upper end of the annular plate is provided with a snap-fit ​​ring with a "T" shaped cross-section, and the bottom end of the top cover plate is provided with a snap-fit ​​groove that matches the snap-fit ​​ring. The snap-fit ​​ring is located in the snap-fit ​​groove and is slidably connected to the side wall of the snap-fit ​​groove.

[0015] In a preferred embodiment, the inner wall of the mounting sleeve is provided with multiple snap-fit ​​plates, and the outer side of the drive shaft is provided with multiple rectangular slots that are adapted to the snap-fit ​​plates. The multiple snap-fit ​​plates are respectively located in the multiple rectangular slots, and each of them is provided with a compression spring at one end. The other ends of the multiple compression springs are respectively provided on one side of the multiple rectangular slots.

[0016] To accommodate reactors of different sizes and specifications, each of the mounting plates is rotatably connected to a threaded rod on one side, and each of the mounting frames is provided with a threaded hole that matches the threaded rod on one side.

The multiple limiting plates pass through the multiple limiting grooves and are slidably connected to the side wall of the limiting groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model achieves dynamic contact between the scraper and the inner wall of the reactor by setting multiple positioning rods and multiple limiting springs on one side of multiple sets of scrapers, and cooperating with an axially sliding mounting sleeve. This ensures that the scraper always maintains a constant contact pressure. The mounting sleeve drives multiple scrapers to move up and down reciprocally, so that multiple scrapers can clean the inner wall of the reactor from different directions. This not only significantly improves the peeling efficiency of stubborn residues such as high-viscosity polymers and biocolloids, but also extends the continuous operation cycle of the equipment by reducing cleaning dead corners, making the reactor for the preparation of biochemical products more practical.

[0020] 2. This utility model, through the threaded rods set on one side of multiple mounting plates and the threaded holes on one side of multiple mounting frames, allows operators to precisely control the radial displacement of the scraper assembly simply by rotating the threaded rods. The self-locking characteristics of the threaded pair ensure the stability of the position after adjustment. It can not only efficiently match different specifications of reactors, but also significantly improve the versatility of the cleaning components by covering complex geometric surfaces, providing reliable technical support for the standardized maintenance of multiple reactor models.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1:

[0028] Please see Figure 1-4 This utility model provides a reaction vessel for preparing biochemical products, comprising:

[0029] Reactor body 1 and top cover plate 2;

[0030] The drive shaft 3 is rotatably connected to the bottom end of the top cover plate 2. The bottom end of the drive shaft 3 extends into the reactor body 1 and is fitted with an installation sleeve 4 on the outside. Multiple stirring blades 5 are provided on the outside of both the drive shaft 3 and the installation sleeve 4, and multiple support rods 6 are provided on the outside of the installation sleeve 4.

[0031] Multiple scrapers 7 are all pressed against the inner wall of the reactor body 1. Multiple support rods 6 located on the same side are provided with the same "U"-shaped mounting frame 8. Each mounting frame 8 is provided with a mounting plate 9. The multiple scrapers 7 are located on one side of the multiple mounting plates 9 respectively.

[0032] An annular plate 10 is located at the bottom of the top cover plate 2. A fixing ring 11 is provided on the outer side of the upper end of the mounting sleeve 4. A feed inlet 12 is provided on one side of the upper end of the top cover plate 2. A discharge outlet 13 is provided at the bottom end of the reactor body 1.

[0033] Specifically, such as Figure 2 and Figure 3 As shown, multiple scrapers 7 are provided with multiple positioning rods 14 on one side, and multiple mounting plates 9 are provided with positioning holes that are adapted to the positioning rods 14 on one side. The multiple positioning rods 14 are located in the multiple positioning holes respectively, and each is provided with a limiting spring 15. The other end of the multiple limiting springs 15 is respectively provided on one side of the multiple positioning holes.

[0034] Through its design, multiple positioning rods 14, in conjunction with multiple positioning holes, can limit the movement of multiple scrapers 7, enabling them to precisely press against the inner wall of the reactor used for preparing biochemical products, thus ensuring the stability of cleaning materials on the inner wall of the reactor. Multiple limiting springs 15 ensure that multiple scrapers 7 can always press against the inner wall of the reactor used for preparing biochemical products, thus ensuring the effectiveness of cleaning materials adhering to the inner wall.

[0035] Specifically, such as Figure 2 and Figure 3 As shown, the bottom end of the annular plate 10 is provided with multiple first contact blocks 16, and the upper end of the fixing ring 11 is provided with multiple second contact blocks 17. The multiple first contact blocks 16 and the multiple second contact blocks 17 are all hemispherically arranged. The multiple first contact blocks 16 abut against the upper end of the multiple second contact blocks 17. The multiple hemispherical first contact blocks 16 and the multiple second contact blocks 17 can make the multiple first contact blocks 16 and the multiple second contact blocks 17 intermittently contact each other when the mounting sleeve 4 rotates, thereby pushing the mounting sleeve 4 and the multiple scrapers 7 to move up and down. This not only increases the cleaning range of the inner wall of the reactor for preparing biochemical products, but also allows the multiple scrapers 7 to move in different directions, thereby improving the cleaning effect of the material on the inner wall of the reactor for preparing biochemical products.

[0036] Specifically, such as Figure 2 and Figure 4 As shown, a positioning shaft 18 is provided through one side of the top cover plate 2. Both the drive shaft 3 and the positioning shaft 18 are provided with pulleys on their outer sides. The two pulleys are provided with the same transmission belt 19. The drive shaft 3 can drive the positioning shaft 18 to rotate through the transmission belt 19. A positioning wheel 20 is provided on the outer side of the positioning shaft 18. An external toothed ring 21 that meshes with the positioning wheel 20 is provided on the outer side of the annular plate 10. Through the positioning wheel 20 and the external toothed ring 21, the positioning shaft 18 can drive the annular plate 10 to rotate in the opposite direction, thereby enabling multiple first contact blocks 16 and multiple second contact blocks 17 to rotate in the opposite direction, making the multiple scrapers 7 move up and down more frequently, thus improving the cleaning effect on the inner wall of the reaction vessel for the preparation of biochemical products. A drive motor 22 is provided at the upper end of the top cover plate 2. The drive motor 22 is existing technology and will not be described in detail here. The upper end of the drive shaft 3 is located at the output end of the drive motor 22.

[0037] Specifically, such as Figure 2 and Figure 4 As shown, the upper end of the annular plate 10 is provided with a snap ring 23 with a cross-section in the shape of a "T". The bottom end of the top cover plate 2 is provided with a snap groove that is adapted to the snap ring 23. The snap ring 23 is located in the snap groove and is slidably connected to the side wall of the snap groove. Through the snap ring 23 with a cross-section in the shape of a "T" and the snap groove, the position of the annular plate 10 can be limited without affecting its rotation.

[0038] Specifically, such as Figure 2 As shown, the inner wall of the mounting sleeve 4 is provided with multiple snap-fit ​​plates 24, and the outer side of the drive shaft 3 is provided with multiple rectangular slots that are adapted to the snap-fit ​​plates 24. The multiple snap-fit ​​plates 24 are respectively located in the multiple rectangular slots, and each of them is provided with a compression spring 25 at one end. The other end of the multiple compression springs 25 is respectively provided on one side of the multiple rectangular slots. The multiple snap-fit ​​plates 24 and the multiple rectangular slots can limit the up and down movement of the mounting sleeve 4 to prevent its position from shifting, thereby ensuring the movement position of the multiple scrapers 7. The multiple compression springs 25 can limit the position of the multiple snap-fit ​​plates 24 and the mounting sleeve 4, so that when the multiple first abutting blocks 16 and the multiple second abutting blocks 17 are separated, the mounting sleeve 4 and the multiple scrapers 7 can be driven to return to their original positions, thereby enabling the multiple scrapers 7 to move up and down reciprocally.

[0039] Example 2:

[0040] Please see Figure 1-4 This utility model provides a reaction vessel for preparing biochemical products, comprising:

[0041] Reactor body 1 and top cover plate 2;

[0042] The drive shaft 3 is rotatably connected to the bottom end of the top cover plate 2. The bottom end of the drive shaft 3 extends into the reactor body 1 and is fitted with an installation sleeve 4 on the outside. Multiple stirring blades 5 are provided on the outside of both the drive shaft 3 and the installation sleeve 4, and multiple support rods 6 are provided on the outside of the installation sleeve 4.

[0043] Multiple scrapers 7 are all pressed against the inner wall of the reactor body 1. Multiple support rods 6 located on the same side are provided with the same "U"-shaped mounting frame 8. Each mounting frame 8 is provided with a mounting plate 9. The multiple scrapers 7 are located on one side of the multiple mounting plates 9 respectively.

[0044] An annular plate 10 is located at the bottom of the top cover plate 2. A fixing ring 11 is provided on the outer side of the upper end of the mounting sleeve 4. A feed inlet 12 is provided on one side of the upper end of the top cover plate 2. A discharge outlet 13 is provided at the bottom end of the reactor body 1.

[0045] Specifically, such as Figure 2 and Figure 3 As shown, each of the multiple mounting plates 9 is rotatably connected to a threaded rod 26 on one side, and each of the multiple mounting frames 8 is provided with a threaded hole adapted to the threaded rod 26 on one side. The multiple threaded rods 26 pass through the multiple threaded holes respectively and are threadedly connected to the side wall of the threaded hole.

[0046] Its design allows the mounting plate 9 and scraper 7 to move by rotating the threaded rod 26, enabling it to adapt to reaction vessels for the preparation of biochemical products of different sizes and specifications. It can also significantly improve the versatility of the cleaning components by covering complex geometric surfaces.

[0047] Specifically, such as Figure 2 and Figure 3 As shown, each of the multiple mounting plates 9 has a limiting plate 27 at both ends, and each of the multiple mounting frames 8 has a limiting groove that is adapted to the limiting plate 27 through both sides. The multiple limiting plates 27 pass through the multiple limiting grooves respectively and are slidably connected to the side wall of the limiting groove. The limiting plates 27 and the limiting grooves can limit the movement of the mounting plates 9 and the scraper 7, prevent their position from shifting, and ensure the cleaning effect on the inner wall of the reactor for the preparation of biochemical products.

[0048] See Figure 1-4 When using a reactor for preparing biochemical products, the material is first added into the reactor body 1 through the feed inlet 12. Then, according to the dimensions of the reactor body 1, multiple threaded rods 26 are rotated. These rods 26 drive multiple mounting plates 9 and multiple scrapers 7 to move, causing the scrapers 7 to press against the inner wall of the reactor body 1. During cleaning, the drive motor 22 is started. The output of the drive motor 22 drives the drive shaft 3 to rotate. The drive shaft 3, through multiple snap-fit ​​plates 24, drives the mounting sleeve 4 to rotate. The mounting sleeve 4 then drives multiple support rods 6 and multiple mounting frames 8 to rotate. The mounting frames 8 then drive the mounting plates 9 and multiple scrapers 7 to rotate, thus cleaning the residue on the inner wall of the reactor body 1. When the attached material is cleaned, the drive shaft 3 rotates, which in turn drives the positioning shaft 18 to rotate via the transmission belt 19. The positioning shaft 18 drives the external toothed ring 21 and the annular plate 10 to rotate in opposite directions via the positioning wheel 20. When the mounting sleeve 4 rotates, it drives the fixing ring 11 to rotate, so that multiple first contact blocks 16 and multiple second contact blocks 17 can make intermittent contact, which can push the mounting sleeve 4 to move up and down, thereby driving multiple scrapers 7 to move. This not only increases the cleaning range of multiple scrapers 7 and improves the peeling efficiency of stubborn residues such as high viscosity polymers and biocolloids, but also allows multiple scrapers 7 to clean materials from different directions, making the reaction vessel for the preparation of biochemical products more practical.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
