Description

Technical Field

[0001] This utility model relates to the field of bioenzyme concentration technology, and in particular to a bioenzyme concentration device. Background Technology

[0002] With the development of bio-enzyme concentration technology, various bio-enzyme concentration devices have been widely used in fields such as biomedicine, food processing, and chemical production. However, existing equipment still has many problems in practical applications, such as low concentration efficiency, easy enzyme inactivation, complex operation, and difficulty in achieving continuous operation, which limits its further promotion in industrial production. A search revealed an evaporation concentration device for bio-enzyme preparations, with publication number CN118477327B and publication date October 25, 2024. This device uses a liquid film forming mechanism and an evaporation control mechanism set in a vacuum chamber to form a liquid film on a conveyor belt for evaporation concentration of the enzyme preparation solution, thereby increasing the evaporation efficiency by increasing the heating area. Although this structure can improve the concentration rate to some extent, it relies on a fixed conveyor belt system, and the liquid film forming process is easily affected by the solution viscosity, leading to uneven coating and affecting heat transfer uniformity. At the same time, the device lacks the ability to dynamically adjust the liquid film thickness, and is prone to drying or coking when processing high-concentration or high-viscosity enzyme solutions, causing enzyme protein denaturation and inactivation. Furthermore, its scraping assembly is a fixed structure, which cannot adjust the scraping position in real time according to the concentration progress, resulting in a high residue rate and limited yield. A search revealed a coating-type evaporation and concentration device for biological enzymes, published on February 23, 2021, with publication number CN111647508B. This device uses a rotating support mechanism in conjunction with a coating wheel to uniformly coat the enzyme solution onto the heating surface, achieving low-temperature evaporation under vacuum. While this design effectively reduces the risk of enzyme inactivation at high temperatures, the gap between the coating wheel and the support mechanism is not adjustable, making it difficult to adapt to the coating requirements of enzyme solutions of different viscosities. This can easily lead to excessively thick coatings or layering, affecting evaporation efficiency and product quality consistency. In addition, the device uses a static scraper structure, which can only scrape the concentrate at a fixed position, making continuous discharge impossible and requiring shutdown for cleaning, thus failing to meet the requirements of continuous production. Simultaneously, its heating surface is temperature-controlled as a whole, with weak regional temperature difference regulation capabilities, and local overheating may still lead to a decrease in enzyme activity. The aforementioned problems indicate that current bio-enzyme concentration devices generally suffer from technical defects such as inaccurate liquid film control, uneven heat transfer, easy enzyme inactivation, inability to operate continuously, and high residue rates, making it difficult to simultaneously meet the dual requirements of high-efficiency concentration and preservation of enzyme activity. Therefore, there is an urgent need to provide a novel bio-enzyme concentration device with optimized structure, intelligent operation, adaptability to various enzyme solution characteristics, and continuous and stable operation to overcome the shortcomings of existing technologies and improve concentration efficiency and product quality. Utility Model Content

[0003] This utility model relates to a biological enzyme concentration device, comprising a concentration chamber, a liquid film forming component, a dynamic adjustment component, and a scraping and recovery component. The liquid film forming component is installed inside the concentration chamber, the dynamic adjustment component is disposed on the inner wall of the concentration chamber, and the scraping and recovery component is installed on one outer wall of the concentration chamber.

[0004] The liquid film forming assembly includes a rotating disk, a drive motor, guide channels, and spray heads. The drive motor is fixedly connected to the top center of the concentration chamber, and the rotating disk is fixedly connected to the bottom end of the drive motor's output shaft. Guide channels are evenly distributed on the outer wall of the rotating disk, and the ends of the guide channels are connected to spray heads. The outlet end of the spray head faces the inner wall of the concentration chamber, and the distance between the outlet end of the spray head and the inner wall of the concentration chamber is adjustable.

[0005] The dynamic adjustment assembly includes an adjusting rod, a sliding block, an elastic element, and a limiting groove. Limiting grooves are symmetrically formed on both sides of the inner wall of the concentration chamber. A sliding block is slidably connected within each limiting groove. An adjusting rod is fixed to one outer wall of the sliding block, and the other end of the adjusting rod extends to the outside of the concentration chamber and is fitted with a manual knob. An elastic element is fixed to the other outer wall of the sliding block, with one end fixed to the inner wall of the limiting groove. The elastic element is made of high-temperature resistant spring steel. The adjusting rod's position is adjusted by the sliding of the sliding block within the limiting groove, and the elastic element provides a restoring force to maintain the stability of the adjusting rod.

[0006] The scraping and recycling assembly includes a scraper, a telescopic mechanism, a collection trough, and a transmission gear. The telescopic mechanism is installed on one outer wall of the concentration chamber, and a scraper is fixedly connected to the output end of the telescopic mechanism. One outer wall of the scraper is attached to the inner wall of the concentration chamber. A transmission gear is installed at the bottom of the telescopic mechanism and meshes with a rack at the bottom of the concentration chamber. A collection trough is located below the scraper and is fixed to the outer wall of the concentration chamber by bolts.

[0007] The concentration chamber has a feed inlet on one side of its top and a discharge outlet on one side of its bottom. The feed inlet and discharge outlet are connected by a pipe, and a flow control valve is installed on the pipe. Support frames are symmetrically fixed to the outer wall of the concentration chamber. A control panel is installed at one end of the support frame, and operation buttons are distributed on one side of the outer wall of the control panel.

[0008] The spray head has a flow divider inside, and the surface of the flow divider is evenly distributed with micropores, the diameter of which ranges from 0.1 mm to 0.5 mm. The spray head uses the flow divider to evenly disperse the enzyme solution into fine droplets, thereby reducing the difference in liquid film thickness.

[0009] The blade of the scraper is made of a corrosion-resistant alloy material, and its surface is coated with an anti-stick coating. The thickness of the scraper gradually increases from the blade edge to the back of the blade to enhance its rigidity. The telescopic mechanism enables the scraper to move up and down through the meshing of a transmission gear and a rack, and the range of movement is limited by a limiting block.

[0010] The technical effects of this utility model are reflected in several aspects:

[0011] First, the liquid film forming component, through the cooperation of a rotating disk and a spray head, uses a guide channel to evenly distribute the enzyme solution onto the inner wall of the concentration chamber, solving the problem of uneven liquid film coating in existing technologies. The distance between the outlet end of the spray head and the inner wall of the concentration chamber is adjustable, which can adapt to the needs of enzyme solutions of different viscosities and avoid the occurrence of excessively thick liquid films or discontinuities.

[0012] Secondly, the dynamic adjustment component achieves dynamic adjustment of the liquid film thickness through the cooperation of the adjusting rod and the sliding block. The rebound force of the elastic element ensures the stability of the adjusting rod after adjustment, while the design of the limiting groove restricts the movement range of the sliding block, preventing over-adjustment from causing the liquid film to rupture or dry out.

[0013] Furthermore, the scraper recovery assembly achieves real-time position adjustment of the scraper through the cooperation of a telescopic mechanism and transmission gears. The scraper's blade design and anti-stick coating effectively reduce the residue rate, while the collection tank facilitates continuous recovery of the concentrate without requiring machine downtime for cleaning, thus meeting the requirements of continuous production.

[0014] Finally, the overall structural design of the concentration chamber optimizes heat transfer uniformity, and the flow divider of the spray head further refines the liquid film distribution, reducing the possibility of local overheating and thus lowering the risk of enzyme activity decline.

[0015] In summary, this invention solves the problems of inaccurate liquid film control, uneven heat transfer, difficulty in continuous operation, and high residue rate in the prior art by synergistically combining the liquid film forming component, dynamic adjustment component, and scraping recovery component, thus significantly improving the concentration efficiency and product quality of the bio-enzyme concentration device.

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

[0023] Specific implementation examples are given below.

[0024] This invention provides a biological enzyme concentration device, the structure of which includes a concentration chamber, a liquid film forming component, a dynamic adjustment component, and a scraping and recovery component. The specific embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, the main body of the device is a concentration chamber, with a drive motor 2 fixedly connected to its top center. The bottom end of the output shaft of the drive motor 2 is fixedly connected to a rotating disk 1, which is located inside the concentration chamber and coaxially arranged with the drive motor 2. Multiple guide grooves 3 are evenly distributed on the outer wall of the rotating disk 1. Each guide groove 3 has a spray head 4 connected to its end, with the outlet end of the spray head 4 facing the inner wall of the concentration chamber. The spray head 4 is installed at the end of the guide groove 3 via a threaded structure. The distance between its outlet end and the inner wall of the concentration chamber can be adjusted manually using a knob to meet the needs of enzyme solutions of different viscosities. Figure 2 As shown, the spray head 4 has a flow divider 20 inside. The surface of the flow divider 20 is evenly distributed with micropores ranging from 0.1 mm to 0.5 mm in diameter. The micropores are used to disperse the enzyme solution into fine droplets, thereby optimizing the liquid film distribution.

[0026] The inner wall of the concentration chamber has symmetrically arranged limiting grooves 8 on both sides. A sliding block 6 is slidably connected within each limiting groove 8. An adjusting rod 5 is fixed to one outer wall of the sliding block 6, and the other end of the adjusting rod 5 extends to the outside of the concentration chamber and is fitted with a manual knob. An elastic element 7 is fixed to the other outer wall of the sliding block 6. One end of the elastic element 7 is fixed to the inner wall of the limiting groove 8. The elastic element 7 is made of high-temperature resistant spring steel. Figure 3 As shown, the position of the adjusting rod 5 is adjusted by the sliding of the sliding block 6 in the limiting groove 8. The elastic element 7 provides a rebound force to maintain the stability of the adjusting rod 5. At the same time, the design of the limiting groove 8 limits the movement range of the sliding block 6 to prevent excessive adjustment from causing the liquid film to rupture or dry out.

[0027] A telescopic mechanism 10 is installed on one outer wall of the concentration chamber. A scraper 9 is fixedly connected to the output end of the telescopic mechanism 10, and one outer wall of the scraper 9 is attached to the inner wall of the concentration chamber. The blade of the scraper 9 is made of corrosion-resistant alloy material, and the blade surface is coated with an anti-stick coating. The thickness of the scraper 9 gradually increases from the blade edge to the back of the blade to enhance its rigidity. A transmission gear 12 is installed at the bottom of the telescopic mechanism 10, and the transmission gear 12 is meshed with a rack 13 at the bottom of the concentration chamber. Figure 4 As shown, a collection groove 11 is provided below the scraper 9. The collection groove 11 is fixed to the outer wall of the concentration chamber by bolts. The telescopic mechanism 10 realizes the up and down movement of the scraper 9 through the meshing of the transmission gear 12 and the rack 13. The movement range is limited by the limit block 21.

[0028] A feed inlet 14 is located on one side of the top of the concentration chamber, connecting to one end of a pipe. The other end of the pipe connects to an outlet 15, which is located on one side of the bottom of the concentration chamber. A flow control valve 16 is installed on the pipe to regulate the flow rate of the enzyme solution. Support frames 17 are symmetrically fixed to the outer wall of the concentration chamber. A control panel 18 is installed at one end of the support frame 17. Operating buttons 19 are distributed on one side of the outer wall of the control panel 18 to control the operation of the drive motor 2, the telescopic mechanism 10, and the flow control valve 16.

[0029] In actual operation, the enzyme solution enters the concentration chamber through the feed inlet 14 and flows into the rotating disk 1 after being regulated by the flow control valve 16. The drive motor 2 drives the rotating disk 1 to rotate, and the enzyme solution flows along the guide channel 3 under the action of centrifugal force, and is evenly distributed to the inner wall of the concentration chamber through the spray head 4. The flow divider 20 inside the spray head 4 disperses the enzyme solution into fine droplets, reduces the difference in liquid film thickness, and ensures uniform liquid film distribution.

[0030] The dynamic adjustment component allows the position of the adjusting rod 5 to be adjusted manually via a knob, causing the sliding block 6 to slide within the limiting groove 8, thereby changing the distance between the adjusting rod 5 and the inner wall of the concentration chamber. The elastic element 7 provides a restoring force, ensuring the stability of the adjusting rod 5 after adjustment. When the enzyme solution viscosity is high, the distance between the adjusting rod 5 and the inner wall can be increased; when the enzyme solution viscosity is low, the distance can be decreased to accommodate enzyme solutions of different viscosities.

[0031] The scraping and recovery assembly, via the telescopic mechanism 10, moves the scraper 9 up and down along the inner wall of the concentration chamber. The blade of the scraper 9 fits tightly against the inner wall of the concentration chamber, scraping off the residue formed during the concentration process and allowing it to fall into the collection tank 11. The meshing of the transmission gear 12 and the rack 13 ensures smooth and reliable movement of the scraper 9, while the limiting block 21 restricts the movement range of the scraper 9, preventing it from exceeding the working area. The collection tank 11 is bolted to the outer wall of the concentration chamber for easy disassembly and cleaning.

[0032] The overall structural design of the concentration chamber optimizes heat transfer uniformity, and the flow divider 20 of the spray head 4 further refines the liquid film distribution, reducing the possibility of local overheating. The operation of the drive motor 2, the telescopic mechanism 10, and the flow control valve 16 can be controlled separately via the operation buttons 19 on the control panel 18, achieving automated operation.

[0033] The above describes the specific implementation of this utility model. Through the synergistic effect of the liquid film forming component, the dynamic adjustment component, and the scraping and recovery component, the problems of inaccurate liquid film control, uneven heat transfer, difficulty in continuous operation, and high residue rate in the prior art are solved, which significantly improves the concentration efficiency and product quality of the bio-enzyme concentration device.

[0034] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0035] In actual operation, the enzyme solution to be concentrated is first introduced into the concentration chamber through the feed inlet 14. The flow control valve 16 adjusts the inflow rate of the enzyme solution according to preset parameters to ensure that the enzyme solution enters the rotating disk 1 at a suitable flow rate. After the drive motor 2 starts, it drives the rotating disk 1 to rotate at high speed. Under the action of centrifugal force, the enzyme solution flows outward along the guide groove 3 and is evenly distributed to the inner wall of the concentration chamber through the spray head 4. During this process, the micropores inside the flow divider 20 disperse the enzyme solution into fine droplets, thereby making the liquid film thickness more uniform. This design effectively avoids the problem of uneven heat transfer caused by local excessively thick or thin liquid films by reducing the difference in liquid film thickness, and at the same time reduces the risk of enzyme solution denaturation and inactivation in high-temperature areas.

[0036] Subsequently, the dynamic adjustment component comes into play. The operator manually adjusts the position of the adjusting rod 5 using a knob, causing the sliding block 6 to slide within the limiting groove 8, thereby changing the distance between the adjusting rod 5 and the inner wall of the concentration chamber. When processing high-viscosity enzyme solutions, the distance between the adjusting rod 5 and the inner wall can be appropriately increased to prevent the liquid film from becoming too thick and reducing evaporation efficiency; while when processing low-viscosity enzyme solutions, the distance between the adjusting rod 5 and the inner wall is decreased to ensure that the liquid film can evenly cover the inner wall of the concentration chamber. The elastic element 7 provides a restoring force during adjustment, maintaining the stability of the adjusting rod 5, while the design of the limiting groove 8 restricts the movement range of the sliding block 6, preventing liquid film rupture or drying due to over-adjustment.

[0037] Simultaneously, the scraping and recovery assembly operates synchronously. The telescopic mechanism 10, through the meshing of the transmission gear 12 and rack 13, drives the scraper 9 to move up and down along the inner wall of the concentration chamber. The blade of the scraper 9 closely adheres to the inner wall of the concentration chamber, scraping off the residue formed during the concentration process and allowing it to fall into the collection tank 11. The limiting block 21 restricts the movement range of the scraper 9, ensuring its smooth operation within the working area. Furthermore, the blade of the scraper 9 is made of a corrosion-resistant alloy material and coated with an anti-stick coating, effectively reducing the adhesion of concentrate and further lowering the residue rate. The collection tank 11 is bolted to the outer wall of the concentration chamber for easy disassembly and cleaning, thus meeting the needs of continuous production.

[0038] Throughout the concentration process, the overall structural design of the concentration chamber optimizes heat transfer uniformity. The spray head 4, through the flow divider 20, refines the enzyme solution into uniformly distributed droplets, significantly reducing the possibility of localized overheating. The operation buttons 19 on the control panel 18 are used to control the operation of the drive motor 2, the telescopic mechanism 10, and the flow control valve 16, respectively, achieving automated operation of the device. Through the aforementioned synergistic effects, this invention solves the problems of inaccurate liquid film control, uneven heat transfer, difficulty in continuous operation, and high residue rates in existing technologies, significantly improving the concentration efficiency and product quality of the bio-enzyme concentration device.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
