Technical Field
[0001] This utility model relates to the field of mixing equipment technology, specifically a multi-strain compound bacterial mixing machine. Background Technology
[0002] In fields such as microbial fermentation, bioengineering, and aquaculture, the proportional mixing of multiple microbial strains is a crucial step, directly impacting the quality and performance of subsequent products. The synergistic effect between different strains requires precise proportion control and thorough mixing contact; therefore, mixing equipment used to achieve this process is a key piece of equipment in related production stages. This equipment must meet requirements such as simultaneous addition of multiple strains, precise proportion control, and uniform and efficient mixing to ensure that the compound microorganisms can exert optimal effectiveness in subsequent cultivation, reactions, or applications. Especially in large-scale production, the structural rationality, ease of operation, and mixing efficiency of the mixing equipment have a significant impact on production progress and cost control.
[0003] Currently, existing mixing equipment for multi-strain ratio compound bacteria typically employs a single stirring device combined with a simple liquid injection structure. The liquid injection structure is mostly a single set or fixed-position injection pipe, and the injection of the bacterial solution is controlled manually or by a single power source. The injection position is relatively fixed, making it difficult to achieve precise addition at different stages and in different areas.
[0004] However, the injection position of the existing injection structure is fixed, and the injection point cannot be adjusted according to the needs of the mixing stage. The bacterial solution can only be injected in a single area, which makes it difficult to achieve the step-by-step mixing of the initial bottom mixing and the subsequent top addition, thus affecting the fusion effect of different bacterial strains at different stages.
[0005] The stirring structure is mostly single-axis stirring, which has limited stirring direction and range, and is prone to mixing blind zones, resulting in local aggregation of bacterial solutions and insufficient mixing uniformity. Utility Model Content

The sealing plug is inserted into the inner wall of the arc concave surface of the liquid guiding ring. Multiple first liquid outlet holes are opened on the side wall of the liquid inlet pipe. The first liquid outlet holes are located inside the cavity structure of the liquid guiding ring.
[0010] As a preferred embodiment, the liquid injection assembly further includes a baffle plate, which has an arc-shaped structure and is fixed inside the liquid guiding ring. Two baffle plates are mirror images of each other about the vertical center line of the liquid guiding ring. The air guiding assembly is fixed to the top side wall of the baffle plate, and the first stirring assembly is disposed between the two baffle plates.
[0011] As a preferred embodiment, the air guide assembly includes a second fixing seat fixed to the outer wall of the mixing tank.

[0012] As a preferred embodiment, the first stirring assembly includes a first motor disposed on the side wall of the support, the rotating end of the first motor is connected to a first rotating shaft, the first rotating shaft is rotatably connected to the inside of the mixing tank, and a first spiral stirring blade is sleeved and fixed on the outer wall of the first rotating shaft.
[0013] As a preferred embodiment, two sets of the second stirring assembly are arranged mirror images of the vertical centerline of the support. The second stirring assembly is located inside the opening structure of the liquid guiding ring, and the structure of the second stirring assembly is the same as that of the first stirring assembly.

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. 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.
[0027] Example: This utility model provides a technical solution for a compound microbial multi-strain ratio mixing machine, such as... Figures 1-6 As shown, the system includes a base plate 100, with two supports 200 fixed to the top surface of the base plate 100. A mixing tank 400 is fixed between the two supports 200. A first stirring assembly 500 and a second stirring assembly 600 are connected through one side of the mixing tank 400. A support plate 300 is fixed between the bottom surface of the mixing tank 400 and the top surface of the base plate 100. A liquid injection assembly 700 is installed through the top surface of the mixing tank 400. Multiple sets of liquid injection assemblies 700 are arranged along the axis of the mixing tank 400. An air guide assembly 800 is installed through the interior of the mixing tank 400. Two sets of air guide assemblies 800 are mirrored about the vertical center line of the mixing tank 400. An air outlet pipe 410 is connected through the top surface of the mixing tank 400, and a liquid outlet pipe 420 is connected through the bottom surface of the mixing tank 400.
[0028] The liquid injection assembly 700 includes a liquid guiding component 710 that penetrates and connects to the inside of the mixing tank 400. The bottom end of the liquid guiding component 710 is connected to a liquid inlet pipe 720. The bottom end of the liquid inlet pipe 720 is connected to a liquid guiding ring 730. The liquid guiding ring 730 is fixed to the inner wall of the mixing tank 400. The inside of the liquid guiding ring 730 is a cavity structure. The bottom of the liquid guiding ring 730 is an open structure. Multiple second liquid outlet holes 731 are provided through the open structure at the bottom of the liquid guiding ring 730.
[0029] Multiple sets of injection components 700 can be used to add various bacterial solutions, the air guide component 800 helps to disperse the bacterial solution, and the first stirring component 500 and the second stirring component 600 can stir and mix the bacterial solution. The overall structural design enables the mixer to perform the proportional mixing of multiple bacterial strains in a relatively efficient manner.
[0030] Furthermore, the liquid guiding component 710 includes a first fixing seat 711 fixed to the outer wall of the mixing tank 400. A pneumatic rod 712 is inserted into the top surface of the first fixing seat 711. A lifting plate 713 is connected to the telescopic top end of the pneumatic rod 712. A guide tube 714 is connected through one side of the lifting plate 713. The guide tube 714 is connected through to the liquid inlet pipe 720. A stop ring 721 is sleeved on the outer wall of the liquid inlet pipe 720. A sealing plug 715 is fixed at the bottom end of the liquid inlet pipe 720. The sealing plug 715 is inserted into the inner wall of the arc concave surface of the liquid guiding ring 730. A plurality of first liquid outlet holes 7141 are opened on the side wall of the liquid inlet pipe 720. The first liquid outlet holes 7141 are located inside the cavity structure of the liquid guiding ring 730.
[0031] The pneumatic rod 712 can drive the lifting plate 713 to move, thereby controlling the position of the insertion tube 714 in the liquid inlet tube 720, and thus controlling the sealing state of the sealing plug 715 on the liquid guide ring 730 and the opening and closing of the first liquid outlet hole 7141. When it is necessary to inject the bacterial solution from the bottom, the solution can be injected into the liquid guide ring 730 and then discharged through the first liquid outlet hole 7141; when it is necessary to inject from the top, the sealing plug 715 can be opened to allow the solution to be directly discharged from the bottom of the insertion tube 714, realizing different injection methods at different stages, and improving the flexibility and accuracy of mixing.
[0032] Furthermore, the injection assembly 700 also includes a baffle plate 740, which has an arc-shaped structure. The baffle plate 740 is fixed inside the liquid guiding ring 730. Two baffle plates 740 are mirror images of each other about the vertical center line of the liquid guiding ring 730. The air guiding assembly 800 is fixed to the top side wall of the baffle plate 740, and the first stirring assembly 500 is disposed between the two baffle plates 740. The arc-shaped baffle plate 740 fixed inside the liquid guiding ring 730 can guide and block the flow of the bacterial solution within the liquid guiding ring 730, making its distribution more uniform. At the same time, the air guiding assembly 800 is fixed to the top side wall of the baffle plate 740, which facilitates the air blown by the air guiding assembly 800 to better act on the bacterial solution. The first stirring assembly 500 is disposed between the two baffle plates 740, which can more effectively stir the solution. The three work together to improve the mixing efficiency and effect.
[0033] Furthermore, the air guide assembly 800 includes a second fixing seat 820 fixed to the outer wall of the mixing tank 400. An air pump 810 is provided on the top surface of the second fixing seat 820. An air pipe 830 is connected through the bottom end of the air pump 810. The air pipe 830 is connected through the interior of the mixing tank 400. An air outlet box 840 is connected through the bottom end of the air pipe 830. Multiple air outlet holes 841 are opened on the side wall of the air outlet box 840. The airflow generated by the air pump 810 is transmitted to the air outlet box 840 through the air pipe 830, and then blown out through the air outlet holes 841 on the side wall of the air outlet box 840. This allows the bacterial solution discharged from the first liquid outlet hole 7141 to disperse and oscillate, so that the bacterial solution is more evenly distributed in the mixing tank 400. Combined with the stirring assembly, this further improves the uniformity and efficiency of bacterial mixing.
[0034] Furthermore, the first stirring assembly 500 includes a first motor 510 disposed on the side wall of the support 200. The rotating end of the first motor 510 is connected to a first rotating shaft 520, which is rotatably connected to the inside of the mixing tank 400. A first spiral stirring blade 530 is sleeved and fixed on the outer wall of the first rotating shaft 520. The first motor 510 drives the first rotating shaft 520 to rotate, thereby driving the first spiral stirring blade 530 to rotate, stirring the bacterial solution in the mixing tank 400, so that different bacterial solutions can fully contact and mix. Utilizing the structural characteristics of the spiral stirring blade, the solution flow can be better promoted, and the stirring and mixing effect can be improved.
[0035] Furthermore, two sets of the second stirring assembly 600 are mirror images of the vertical center line of the support 200. The second stirring assembly 600 is disposed inside the opening structure of the liquid guiding ring 730. The second stirring assembly 600 and the first stirring assembly 500 have the same structure. The second stirring assembly 600 and the first stirring assembly 500 have the same structure and are mirror images of each other about the vertical center line of the support 200. They are disposed inside the opening structure of the liquid guiding ring 730, which can perform targeted stirring of the inoculum solution near the liquid guiding ring 730. They cooperate with the first stirring assembly 500 to stir the inoculum solution in the mixing tank 400 from different positions and angles, reduce the mixing blind zone, and improve the overall mixing uniformity and efficiency.
[0036] Specifically, the three bacterial solutions are introduced into the three insertion tubes 714 respectively. The three bacterial solutions are introduced into the liquid guiding ring 730 through the first liquid outlet 7141, transported along the cavity structure inside the liquid guiding ring 730, and discharged through the second liquid outlet 731. The first motor 510 and the second motor 610 are started, and the first rotating shaft 520 and the second rotating shaft 620 rotate, driving the first spiral stirring plate 530 and the second spiral stirring plate 630 to rotate and mix the bacterial solutions.
[0037] After mixing for a period of time, the pneumatic rod 712 is activated to pull the lifting plate 713 down, causing the insertion tube 714 to slide inside the liquid inlet pipe 720. The sealing plug 715 opens the arc concave surface of the liquid guide ring 730 until the bottom of the insertion tube 714 extends out, causing the first liquid outlet hole 7141 to open. The inoculum solution that has entered the insertion tube 714 is directly discharged from the top of the mixed inoculum solution. The air pump 810 is activated, and air passes through the air pipe 830 to the air outlet box 840 and is discharged from the air outlet hole 841, causing the inoculum solution discharged from the first liquid outlet hole 7141 to disperse and oscillate, which facilitates the dispersion and mixing of the inoculum solution. This achieves the initial mixing of inoculum solution by adding it from the bottom and then mixing it from the top, thus improving the mixing efficiency of the inoculum.
[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
