Description

Technical Field

[0001] This invention relates to the field of water treatment, specifically to an intelligent microbial inoculation device for water treatment. Background Technology

[0002] With the acceleration of industrialization and the improvement of urbanization, water pollution has become increasingly prominent, and water scarcity and water quality deterioration have become significant bottlenecks restricting sustainable socio-economic development. As a key sector for ensuring water resource security, the water treatment industry has received widespread attention for technological upgrades and efficiency improvements. Among numerous water treatment technologies, biological treatment is widely used in scenarios such as domestic sewage, industrial wastewater, and landscape water body restoration due to its advantages of low cost, environmental friendliness, and no secondary pollution. The core principle of this technology is to utilize the metabolic activity of specific functional bacteria to decompose pollutants such as organic matter, nitrogen, and phosphorus in the water, thereby purifying and improving water quality.

[0003] Currently, the main methods of microbial inoculation on the market are manual inoculation and traditional mechanical inoculation, which have many shortcomings. Manual inoculation relies on the operator's experience and judgment, which is highly subjective and makes it difficult to accurately grasp the dosage and timing of inoculation. While traditional mechanical inoculation reduces reliance on manual labor to some extent, it lacks the ability to select different microbial species for inoculation. For some complex pollution scenarios (such as domestic sewage, combined industrial wastewater, and landscape water body restoration), multiple microbial species need to be inoculated simultaneously. Since the types of microbial species inoculated cannot be controlled, conventional machinery requires multiple inoculation species to be changed before the appropriate inoculation can be performed. However, most microbial inoculation equipment on the market is designed for single-channel, single-species inoculation, which can only achieve the inoculation of one type of microbial species. It cannot meet the needs of complex polluted water bodies for the synergistic treatment of multiple functional microbial species. Furthermore, existing equipment cannot ensure the uniformity of the microbial suspension before inoculation, resulting in incomplete activation and a large number of microbial species remaining in a dormant or inactive state, which directly affects the efficiency of subsequent water treatment. It has poor applicability and cannot meet the needs of actual use.

[0004] Therefore, there is a need to provide an intelligent microbial inoculation device for water treatment, which aims to solve the above problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an intelligent microbial inoculation device for water treatment, which aims to solve the technical problems mentioned in the background art.

[0008] As a further embodiment of the present invention, the uniform dispensing mechanism further includes a first liquid guide pipe and a second liquid guide pipe for driving the infusion cylinder to make infusion connection. The first liquid guide pipe and the second liquid guide pipe are both connected to the interior of the infusion cylinder.

The third connecting rod is rotatably connected to the first support frame through a first connecting shaft.

[0011] As a further embodiment of the present invention, one end of a fourth link is rotatably connected to the end rotation docking area of ​​the second and third links, and the other end of the fourth link is rotatably connected to one end of a fifth link. The other end of the fifth link is rotatably mounted on the first support frame via a second connecting shaft.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] See Figures 1-9 A smart microbial inoculation device for water treatment includes a support plate 1, on which several support platforms 4 are arranged equidistantly in a circle, and each support platform 4 is equipped with a liquid storage tank 5. A rotating platform 2 for controlling rotation is installed at the bottom of the support plate 1. The device also includes: The uniform dispensing mechanism is installed on the liquid storage tank 5 and is used to uniformly stir and dispensing the liquid in the liquid storage tank 5. The uniform dispensing mechanism includes a stirring blade 8 for stirring in the liquid storage tank 5, a liquid delivery cylinder 16 for supplying liquid, and a third link 25 and a fifth link 28 for synchronously driving stirring and supplying liquid. The third link 25 controls stirring and liquid delivery through the rotation of the fifth link 28. The stirring blade 8 and the liquid delivery cylinder 16 are stirred and dispensed through the rotation of the third link 25.

[0031] Furthermore, the uniform dispensing mechanism also includes a lifting toothed plate 10 for driving the stirring blade 8 to stir. The lifting toothed plate 10 is slidably connected to the outside of the liquid storage tank 5 by a guide slide rod 11. One side of the lifting toothed plate 10 is also slidably connected to the first support frame 32 by a first traction rod 12. The stirring blade 8 is rotatably installed inside the liquid storage tank 5 by a stirring shaft 7. One end of the stirring shaft 7 is fixedly connected to a rotating gear 9, which meshes with the lifting toothed plate 10. The liquid storage tank 5 is also provided with a feed pipe 6.

[0032] Furthermore, the uniform dispensing mechanism also includes a first liquid guide pipe 18 and a second liquid guide pipe 20 for driving the infusion cylinder 16 to make infusion connections. Both the first liquid guide pipe 18 and the second liquid guide pipe 20 are connected to the interior of the infusion cylinder 16. The infusion cylinder 16 is fixedly installed on the first support frame 32 by an L-shaped fixing plate 17. One end of the first liquid guide pipe 18 is connected to the interior of the liquid storage tank 5. One end of the second liquid guide pipe 20 is fixedly connected to a spray plate 22. A first one-way valve 19 is provided on the first liquid guide pipe 18, and a second one-way valve 21 is provided on the second liquid guide pipe 20.

[0033] Furthermore, the uniform dispensing mechanism also includes a piston plate 15 for driving the infusion cylinder 16 to perform infusion. The piston plate 15 is slidably connected to the inside of the infusion cylinder 16 by a piston rod 14, and the piston rod 14 is slidably connected to the first support frame 32 by a second traction rod 13.

[0034] Furthermore, the uniform delivery mechanism also includes a first link 23 and a second link 24 for driving the first traction rod 12 and the second traction rod 13 to reciprocate up and down. One end of the first link 23 is rotatably connected to the other end of the first traction rod 12, one end of the second link 24 is rotatably connected to the other end of the second traction rod 13, and the other ends of the first link 23 and the second link 24 are respectively rotatably connected to the two ends of the third link 25. The third link 25 is rotatably connected to the first support frame 32 through the first connecting shaft 26.

[0035] Furthermore, at the end rotation docking area of ​​the second link 24 and the third link 25, one end of the fourth link 27 is rotatably connected, and the other end of the fourth link 27 is rotatably connected to one end of the fifth link 28. The other end of the fifth link 28 is rotatably mounted on the first support frame 32 through the second connecting shaft 29.

[0036] Preferably, when adding microbial inoculum for water treatment, the storage tank 5 can be filled with the corresponding microbial liquid through the feed pipe 6. When the microbial inoculum for water treatment is added, the addition triggering mechanism will engage and drive the operation. At this time, the second connecting shaft 29 will drive the fifth connecting rod 28 to rotate. Under the traction and rotation of the fourth connecting rod 27, the third connecting rod 25 will be driven to swing back and forth around the first connecting shaft 26. At this time, under the traction and rotation of the first connecting rod 23 and the second connecting rod 24, the first traction rod 12 and the second traction rod 13 will be driven to move up and down back and forth. That is, the first connecting rod 23 will drive the lifting tooth plate 10 on the first traction rod 12 to move up and down back and forth. And under the meshing connection between the lifting tooth plate 10 and the rotating gear 9, the stirring blade 8 on the stirring shaft 7 will be driven to swing back and forth, thus completing the stirring of the microbial liquid in the storage tank 5, so as to facilitate subsequent extraction and addition. Correspondingly and synchronously, the second traction rod 13 drives the piston plate 15 on the piston rod 14 to reciprocate up and down inside the infusion cylinder 16. Thus, under the one-way action of the first one-way valve 19 on the first liquid guide tube 18 and the second one-way valve 21 on the second liquid guide tube 20, the infusion cylinder 16 can draw the bacterial liquid from the storage tank 5 through the first liquid guide tube 18. Then, the piston plate 15 pushes the bacterial liquid to the spray plate 22 on the second liquid guide tube 20 for spraying, thus completing the bacterial liquid delivery operation.

[0037] Through this synchronized mixing and dispensing operation, the liquid circulation field in the storage tank 5 can effectively break the tendency of bacterial sedimentation and stratification, so that the bacterial cells are evenly dispersed in the liquid. This avoids problems such as excessive or insufficient bacterial cells in local water bodies due to uneven concentration. Furthermore, through the appropriate liquid extraction and dispensing method, the mixed bacterial liquid can be used for water treatment operations in a timely manner, which is convenient for dynamic dispensing and treatment and significantly improves the efficiency of water treatment.

[0038] like Figures 1-10 As shown, this embodiment, based on the above embodiment, also includes a dispensing trigger mechanism, which is installed at one side connection of the liquid storage tank 5 and is used to trigger and control the uniform dispensing mechanism to work. The dispensing trigger mechanism includes a push plate 37 and a square shaft 30 for triggering movement control. The square shaft 30 is rotatably mounted on the first support frame 32 and the second support frame 33. The push plate 37 is limited and slidably connected to the square shaft 30 through a bushing 34, and the bushing 34 is rotatably mounted on the push plate 37.

[0039] Furthermore, the release triggering mechanism also includes an electric push rod 44 for driving the push plate 37 to move and dock. One end of the square shaft 30 is rotatably connected to the first support frame 32 via the second connecting shaft 29, and the other end of the square shaft 30 is rotatably connected to the second support frame 33 via the third connecting shaft 31. The push plate 37 is slidably connected to the second support frame 33 via the slider 40. The second support frame 33 is provided with a groove 41 adapted to slide the slider 40. The push plate 37 is fixedly connected to the output end of the electric push rod 44, and the electric push rod 44 is fixedly installed on the first support frame 32.

[0040] Furthermore, the release triggering mechanism also includes a driven bevel gear 39 for driving the square shaft 30 to rotate. A first gear 35 is fixedly connected to the bushing 34, and a second gear 36 is meshed with the first gear 35. The second gear 36 is rotatably connected to the push plate 37 through a fourth connecting shaft 38. One end of the fourth connecting shaft 38 is fixedly connected to the driven bevel gear 39. A driving bevel gear 42 is provided on one side of the driven bevel gear 39, which can be meshed with the driven bevel gear 39. The driving bevel gear 42 is fixedly connected to the output shaft of the main drive motor 43. The main drive motor 43 is fixedly mounted on the support plate 1. A protective cover 3 is provided on the outside of the driving bevel gear 42 for protection.

[0041] Preferably, in this embodiment, when the required bacterial liquid is added for different water treatments, the electric push rod 44 on one side of the storage tank 5 is used to drive the addition of the required bacterial liquid. This pushes the driven bevel gear 39 on the push plate 37 to engage with the driving bevel gear 42 on the main drive motor 43. Simultaneously, the main drive motor 43 drives the fourth connecting shaft 38 on the driven bevel gear 39 to rotate while simultaneously driving the driving bevel gear 42 to rotate. The fourth connecting shaft 38 then drives the second gear 36 to rotate. Under the meshing connection between the second gear 36 and the first gear 35, the shaft sleeve 34 drives the square shaft 30 to rotate, thus completing the mixing and addition of the bacterial liquid in the storage tank 5. This device, by setting multiple driven bevel gears 39 for movement and docking, can perform compound addition of single or multiple bacterial liquids, or control the addition operation in sequence. It has a high degree of intelligence, wide applicability, and further improves the efficiency of water treatment.

[0042] The pollutant composition and water quality indicators vary significantly across different water treatment scenarios. Single bacterial strains often only work against specific pollutants and are insufficient to address complex water purification needs. This equipment not only supports independent single-strain dispensing but also has the capability for multi-strain compound dispensing. It eliminates the need for multiple additional dispensing devices, achieving this through modular configuration of the same equipment. This significantly shortens the treatment cycle and allows for precise control over the dispensing order and intervals of bacterial strains based on different water qualities. This adaptability greatly enhances the equipment's operational stability under complex conditions. It not only solves the problems of single dispensing modes and limited scenario adaptability of traditional equipment but also improves water treatment efficiency and effectiveness. It is suitable for various complex water treatment scenarios and is easy to promote and use.

[0043] It should be noted that the components in this application are all general standard parts or parts known to those skilled in the art, which effectively solve the technical problems raised in the background art.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
