Description

Technical Field

[0001] This utility model relates to the field of bacterial-algae symbiotic culture technology, specifically a bacterial-algae symbiotic culture device with product collection function. Background Technology

[0002] The symbiotic culture technology of microalgae relies on the metabolic synergy of microalgae (such as Chlorella and Haematococcus pluvialis) and microorganisms (bacteria, fungi, etc.) to achieve multiple functions of "photosynthetic carbon fixation - pollutant degradation - product accumulation". It has become one of the key technologies to solve the contradiction between environmental governance and resource recycling. However, the process of symbiotic culture of microalgae requires the use of microalgae symbiotic culture devices. However, the existing microalgae symbiotic culture devices still have certain defects in use. As proposed in application number CN202421378701.4, a symbiotic culture device for bacteria and algae includes an incubator. A motor is fixedly connected inside the incubator, and a mixer is fixedly connected to the drive end of the motor. A fence is fixedly connected to the bottom inner wall of the incubator, and an inner box is fixedly connected to the bottom inner wall of the incubator. A cover is provided on the top of the inner box. A receiver is fixedly connected to the bottom inner wall of the inner box, and a valve assembly is fixedly connected to the outer wall of the receiver. A storage tank is fixedly connected to the bottom inner wall of the inner box, and a feed pipe is fixedly connected to the right inner wall of the storage tank. A raw material tank is fixedly connected to the other end of the feed pipe. A ball valve is fixedly connected to the bottom end of the rotating column, and a collection assembly is fixedly connected to the left end of the discharge pipe. In actual use, this symbiotic culture device separates the symbiotic products of bacteria and algae through a filter cloth inside the filter box. However, when the symbiotic products accumulate on the surface of the filter cloth, it affects the filtration effect of the filter cloth, requiring frequent replacement of the filter cloth, thus reducing the convenience of use and filtration efficiency.

[0003] Therefore, we propose a bacterial-algae symbiotic culture device with product collection function to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a symbiotic culture device for bacteria and algae with product collection function, so as to solve the problem mentioned in the background art that the accumulation of symbiotic organisms on the surface of the filter cloth will affect the filtration effect, require frequent replacement of the filter cloth, and reduce the convenience of use and filtration efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bacterial-algae symbiotic culture device with product collection function, comprising a transparent culture tube, a top cover installed at the top of the transparent culture tube, an aeration disc installed at the bottom of the transparent culture tube, a connecting pipe connected to the bottom end of the aeration disc, a solenoid valve connected to the bottom end of the transparent culture tube, a separation box fixedly installed at the bottom end of the solenoid valve, return pipes connected to the bottom sides of the separation box, the top end of the return pipe being fixedly connected through the top of the transparent culture tube, a water pump installed on the return pipe, and a support base fixedly installed at the bottom of the separation box; A collection frame is movably installed inside the separation box, a filter plate is fitted into the bottom of the collection frame, and a scraping mechanism is installed inside the filter plate. A sealing and locking mechanism connects the collection frame and the separation box.

[0006] Preferably, the aeration discs are distributed at equal angles at the bottom of the transparent culture tube, and the aeration discs, together with the connecting pipes, achieve aeration through an external air supply mechanism.

[0007] The above-mentioned structural design, with its equiangular distribution, allows the aeration airflow to diffuse evenly within the transparent culture tube, avoiding localized oxygen deficiency or concentrated airflow. This ensures consistent dissolved oxygen concentration in all areas of the tube, providing a stable and balanced growth environment for bacteria and algae, reducing imbalances in bacterial and algal activity caused by environmental differences, and improving the stability and quality of product formation. The tiny bubbles generated during uniform aeration can cause slight disturbance in the culture medium, promoting full contact between bacteria and algae and nutrients in the culture medium. At the same time, it accelerates the diffusion and discharge of metabolic waste, improves the metabolic efficiency of bacteria and algae, and indirectly increases the amount of product generated.

[0008] Preferably, the scraping mechanism includes a rotating scraper rotatably mounted inside the filter plate, a drive motor is fixedly mounted in the middle of the support base, a rotating rod is fixedly mounted on the shaft end of the drive motor, an inner groove is opened inside the rotating rod, a sliding plate is slidably mounted inside the inner groove, a hexagonal column is fixedly connected to the top surface of the sliding plate, the hexagonal column is slidably connected to the inner groove, and the top end of the hexagonal column is movably inserted into the rotating scraper.

[0009] Preferably, the docking scraping mechanism further includes a knob nut rotatably mounted on the bottom surface of the slide plate, the knob nut being threadedly connected to the bottom of the rotating rod.

[0010] With the above-mentioned structure, the drive motor drives the rotating rod to rotate, and the hexagonal column can stably transmit torque to the rotating scraper, so that the scraper rotates continuously along the surface of the filter plate, actively scraping off the symbiotic organisms accumulated on the filter plate, avoiding the decrease in filtration flow rate caused by filter pore blockage, eliminating the need for frequent shutdowns for cleaning. Through the continuous cleaning of the scraper, the amount of symbiotic organisms accumulated on the surface of the filter plate is greatly reduced, eliminating the need for frequent disassembly and replacement of the filter cloth, reducing operational complexity, and reducing downtime for equipment maintenance. Rotating the knob nut can drive the slide plate to slide along the inner groove of the rotating rod, thereby adjusting the connection and separation of the hexagonal column and the rotating scraper. This facilitates easy disassembly when cleaning the symbiotic organisms inside the collection box, improving the maintenance convenience of the mechanism.

[0011] Preferably, the sealing and engaging mechanism includes a limiting seat fixedly installed at the front end of the collection frame, and a sealing ring is sleeved on the outer rear end of the limiting seat. After the limiting seat and the collection frame are inserted, the sealing ring seals the connection between the two.

[0012] Preferably, the sealing engagement mechanism further includes positioning seats symmetrically installed on the inner wall of the limiting seat. The inner ring of the positioning seat is rotatably connected to a screw, and a rotating handle is fixedly connected between the screws. The outer ring of the screw is threaded with a slider. A engagement plate is fixedly installed on the side of the slider away from the rotating handle. The engagement plate is slidably connected to the positioning seat. Engagement seats are fixedly installed on both sides of the separation box, and the engagement seats are movably engaged with the engagement plate.

[0013] With the above-mentioned structural design, the sealing ring at the rear end of the limiting seat can fit tightly against the connection between the collection frame and the separation box after they are inserted, effectively preventing the culture medium and bacterial and algal products in the separation box from leaking out of the gaps, thus avoiding resource waste and external pollution. Rotating the handle can drive the screws on both sides to rotate synchronously, causing the slider to slide along the positioning seat and drive the locking plate to extend and retract. When the locking plate engages with the locking seat, it can securely fix the collection frame. When separated, the collection frame can be quickly removed without the need for complicated tools, greatly shortening the operation time of product collection and collection frame cleaning, and improving the ease of use of the device.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the bacterial-algae symbiotic culture device with product collection function; 1. The equiangular aeration disc at the bottom of the transparent culture tube can work with the external air supply to evenly diffuse the airflow, ensuring a consistent dissolved oxygen concentration in all areas of the tube. This creates a stable growth environment for bacteria and algae, improving the stability and yield of product generation. The bubbles also cause slight disturbance to the culture medium, promoting contact between bacteria and algae and nutrients and accelerating waste removal. The scraping mechanism uses a drive motor to continuously rotate the scraper, actively cleaning the symbiotic organisms accumulated on the filter plate surface. This effectively avoids slowing down filtration due to filter pore blockage and eliminates the need for frequent shutdowns to replace filter media. At the same time, the connection between the hexagonal column and the scraper can be adjusted by the knob nut, facilitating disassembly and assembly during the cleaning of symbiotic organisms in the collection frame, further reducing the complexity of maintenance operations. 2. The sealing ring of the front limiting seat of the collection frame can fit tightly against the interface of the collection frame and the separation box after they are inserted, effectively preventing the leakage of culture medium or bacterial and algal products from the gaps in the box, avoiding resource waste and external pollution that could damage the culture environment. The sealing and locking mechanism can drive the screws on both sides to rotate synchronously by rotating the handle, driving the locking plate to quickly lock or separate from the locking seat of the separation box. The collection frame can be fixed and disassembled without the need for additional tools, which greatly shortens the time for product collection and collection frame cleaning, and also provides convenience for the centralized collection of bacterial and algal products.

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-7 This utility model provides a technical solution: a bacterial-algae symbiotic culture device with product collection function, including a transparent culture tube 1, a top cover 2 installed at the top of the transparent culture tube 1, an aeration disc 3 installed at the bottom of the transparent culture tube 1, a connecting pipe 4 connected to the bottom of the aeration disc 3, the aeration disc 3 being evenly distributed at the bottom of the transparent culture tube 1, the aeration disc 3 cooperating with the connecting pipe 4 to achieve aeration through an external air supply mechanism, a solenoid valve 5 connected to the bottom of the transparent culture tube 1, a separation box 6 fixedly installed at the bottom of the solenoid valve 5, return pipes 7 connected to the bottom of both sides of the separation box 6, the top of the return pipe 7 being fixedly connected to the top of the transparent culture tube 1, a water pump 26 installed on the return pipe 7, a support base 8 fixedly installed at the bottom of the separation box 6, a collection frame 9 movably installed inside the separation box 6, and a filter plate 10 fitted into the bottom of the collection frame 9; In the above-mentioned structure, the transparent culture tube 1 serves as the core culture container, providing a light-permeable growth space for bacteria and algae. The aeration discs 3, evenly distributed at the bottom, are connected to the external air supply mechanism through the connecting pipe 4. When air is supplied, the airflow is evenly diffused into the transparent culture tube 1 through the aeration discs 3. On the one hand, this continuously replenishes dissolved oxygen for the growth of bacteria and algae, avoiding the imbalance of bacterial and algal activity caused by insufficient local oxygen supply. On the other hand, the microbubbles cause slight disturbance to the culture medium, promoting full contact between bacteria and algae and nutrients in the culture medium, while accelerating the diffusion of metabolic waste, creating a stable and balanced symbiotic environment for bacteria and algae, and ensuring the continuous generation of products. When the bacteria and algae have been cultured to a certain stage and produced symbiotic products, the solenoid valve 5 at the bottom of the transparent culture tube 1 is opened. The culture medium containing the products enters the separation box 6 below under the action of gravity. The collection frame 9 in the separation box 6 and the filter plate 10 embedded at the bottom form a separation structure. When the culture medium passes through the pores of the filter plate 10, the symbiotic products are trapped in the collection frame 9 because their particle size is larger than the pore size of the filter plate 10, thus achieving the separation of the products and the culture medium. The separated clarified culture medium is collected at the bottom of the separation box 6. At this time, the water pump 26 on the return pipe 7 is started, and the clarified culture medium is transported back to the transparent culture tube 1 along the return pipe 7 to participate in the bacteria and algae culture process again, which reduces the waste of culture medium and maintains the stability of the nutrient concentration of the culture system.

[0019] The filter plate 10 is equipped with a docking scraping mechanism, which includes a rotating scraper 11 rotatably installed inside the filter plate 10. A drive motor 12 is fixedly installed in the middle of the support base 8. A rotating rod 13 is fixedly installed at the shaft end of the drive motor 12. An inner groove 14 is opened inside the rotating rod 13. A slide plate 15 is slidably installed inside the inner groove 14. A hexagonal column 16 is fixedly connected to the top surface of the slide plate 15. The hexagonal column 16 is slidably connected to the inner groove 14. The top of the hexagonal column 16 is movably inserted into the rotating scraper 11. The docking scraping mechanism also includes a knob nut 17 rotatably installed on the bottom surface of the slide plate 15. The knob nut 17 is threadedly connected to the bottom of the rotating rod 13. Before the mechanism is activated, the power assembly and the scraping assembly need to be connected. Rotate the knob nut 17 installed on the bottom of the slide plate 15. Because the knob nut 17 is threaded to the bottom of the rotating rod 13, the axial force generated by the threaded engagement will drive the slide plate 15 to slide upward along the inner groove 14 opened inside the rotating rod 13. The hexagonal column 16 fixedly connected to the top surface of the slide plate 15 slides synchronously along the inner groove 14 with the slide plate 15 until the top of the hexagonal column 16 and the rotating scraper 11 rotatably installed inside the filter plate 10 are connected. At this time, the mechanism completes the preparation work for power transmission. When symbiotic organisms accumulate on the surface of the filter plate 10, affecting the filtration efficiency, the drive motor 12, which is fixedly installed in the middle of the support base 8, is started. The shaft end of the drive motor 12 drives the fixedly installed rotating rod 13 to rotate synchronously. The rotating rod 13 transmits the rotational power to the sliding hexagonal column 16 through the internal groove 14. The rotating scraper 11, which is inserted into the hexagonal column 16, rotates inside the filter plate 10. The scraper part of the rotating scraper 11 continuously scrapes along the surface of the filter plate 10, scraping away the symbiotic organisms accumulated in the pores of the filter plate 10 in time and transferring them to the outside of the filter plate 10, so as to avoid the filter pores from being blocked and causing the filtration flow rate to decrease. When it is necessary to disassemble the collection frame 9 to clean the trapped symbiotic organisms inside, or to maintain the rotating scraper 11, turn the knob nut 17 in the opposite direction. The threaded engagement between the knob nut 17 and the rotating rod 13 generates a downward axial force, which drives the slide plate 15 to slide down along the inner groove 14. The slide plate 15 drives the hexagonal column 16 to move down synchronously, so that the top of the hexagonal column 16 is disengaged from the rotating scraper 11. At this time, the rotating scraper 11 is completely separated from the power components such as the drive motor 12 and the rotating rod 13. The collection frame 9 can be directly removed for operation. After maintenance or cleaning is completed, repeat the initial docking steps to re-establish the engagement of each part and restore the docking scraping mechanism to work.

[0020] A sealing and engaging mechanism is connected between the collection frame 9 and the separation box 6. The sealing and engaging mechanism includes a limiting seat 18 fixedly installed at the front end of the collection frame 9. A sealing ring 19 is sleeved on the outer ring of the rear end of the limiting seat 18. After the limiting seat 18 and the collection frame 9 are inserted, the sealing ring 19 seals the connection between the two. The sealing and engaging mechanism also includes a positioning seat 20 symmetrically installed on the inner wall of the limiting seat 18. A screw 21 is rotatably connected to the inner ring of the positioning seat 20. A rotating handle 22 is fixedly connected between the screws 21. A slider 23 is threaded on the outer ring of the screw 21. A engaging plate 24 is fixedly installed on the side of the slider 23 away from the rotating handle 22. The engaging plate 24 and the positioning seat 20 are slidably connected through. Engaging seats 25 are fixedly installed on both sides of the separation box 6. The engaging seats 25 and the engaging plates 24 are movably engaged and connected. When the collection frame 9 needs to be installed into the separation box 6, the limiting seat 18 fixedly installed at the front end of the collection frame 9 is first inserted into the opening end of the separation box 6 until the limiting seat 18 and the separation box 6 are inserted into place. At this time, the sealing ring 19 sleeved on the outer ring of the rear end of the limiting seat 18 is squeezed at the connection between the limiting seat 18 and the separation box 6. The elastic deformation of the sealing ring 19 fills the gap between the two, effectively preventing the leakage of culture medium or product from the interface gap in the separation box 6. Then, the locking and fixing operation is performed. The rotating handle 22, which is fixedly connected to the positioning seats 20 symmetrically installed on the inner wall of the limiting seat 18, is rotated. The rotating handle 22 drives the screws 21 connected to it at both ends to rotate synchronously. Since the outer ring of the screw 21 is threaded with a slider 23, the radial driving force generated by the thread engagement will drive the slider 23 to slide along the inner side of the positioning seat 20 towards the rotating handle 22. The locking plate 24 fixedly installed on the side of the slider 23 away from the rotating handle 22 moves synchronously with the slider 23. The locking plate 24 is slidably connected to the positioning seat 20 through the connection, which can prevent the slider from shifting during sliding. The locking plate 24 is fully locked with the locking seats 25 fixedly installed on both sides of the separation box 6. At this time, the collection frame 9 is firmly fixed in the separation box 6 through the cooperation of the limiting seat 18, the locking plate 24 and the locking seat 25, preventing the collection frame 9 from shaking during the operation of the device and affecting the filtration and separation effect. When it is necessary to remove the collection frame 9 to clean the internal products or for maintenance, rotate the handle 22 in the opposite direction to drive the screw 21 to rotate in the opposite direction. The slider 23 slides along the positioning seat 20 away from the handle 22. The locking plate 24 moves outward and disengages from the locking state with the locking seat 25. At this time, the collection frame 9 can be removed from the separation box 6 by pulling it outward.

[0021] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
