Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a microbial additive device based on microbial water treatment. Background Technology

[0002] Microbial water treatment technology is widely used in the treatment of domestic sewage and industrial wastewater due to its advantages such as environmental friendliness, low cost, and no secondary pollution. The core of this technology lies in the precise and uniform addition of functional microbial strains to the wastewater, enabling pollutant degradation through the metabolic processes of the microorganisms. Therefore, the microbial addition device, as a key component connecting the strain storage and the wastewater treatment system, directly affects water treatment efficiency and strain utilization.

[0003] Therefore, existing technologies have developed microbial additive devices for wastewater treatment. For example, a microbial additive device for wastewater treatment based on microorganisms, patent application number 202220158079.0, uses a transfer pump to transport microorganisms from the bacterial solution tank to a fixed cylinder, from which the bacterial solution is discharged to treat the wastewater in the treatment tank. However, this method of addition has certain drawbacks. Since the fixed cylinder used to discharge the bacterial strain is fixed to one side of the treatment tank, during the addition process, as the bacterial strain spreads, there may be problems with local bacterial concentrations that are too high or too low, resulting in the bacterial strain not being evenly distributed in the treatment tank. Utility Model Content

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, this invention proposes a microbial additive device based on microbial water treatment.

[0005] The technical solution to the technical problem solved by this utility model is as follows: This utility model proposes a microbial addition device based on microbial water treatment, including a treatment tank with a detachable top cover, forming an inlet between the top opening of the treatment tank and the top cover; a microbial culture tank connected to the top cover and having a discharge port; a delivery pump connected to the top cover, with its input end connected to the discharge port and its output end connected to a first delivery pipe, the other end of which passes through the top cover and is placed inside the treatment tank; a second delivery pipe with a discharge hole on its outer wall, horizontally and rotatably connected to the treatment tank and connected to the first delivery pipe; and a drive motor located on the side of the treatment tank, with its output shaft passing through the treatment tank and connected to the second delivery pipe.

[0006] Preferably, at least one set of stirring blades is fixed to the outer wall of the second conveying pipe.

[0007] Preferably, the bottom of the first conveying pipe is detachably connected to a connecting pipe, the connecting pipe having an inverted "T" shape, and the bottom two connecting ends of the connecting pipe are respectively connected to sealed bearings. The inner rings of the two sealed bearings are connected to a connecting cylinder, and the connecting cylinder has a sterilization hole, which is connected to the first conveying pipe. The second conveying pipe includes a first pipe body and a second pipe body, and the opposite ends of the first pipe body and the second pipe body are respectively detachably connected to the sealed bearings.

[0008] Preferably, a support frame is fixed inside the processing box, and a bearing seat is detachably connected to the support frame. The end of the second conveying pipe away from the drive motor is connected to the inner ring of the bearing seat.

[0009] Preferably, the other side of the top cover is hinged with a flip cover for controlling the opening of the water inlet.

[0010] Preferably, a number of support rods are connected between the bottom surface and the top cover of the inoculum box, and the delivery pump is connected between the bottom surface and the top cover of the inoculum box.

[0011] Preferably, a driving component is connected above the inoculum box, and the driving end of the driving component penetrates through the top surface of the inoculum box and is connected to a stirring component for stirring the inside of the inoculum box.

[0012] Preferably, the agitator includes a central rod that is driven by the driving end of the driving component. A scraper is connected to the outer wall of the central rod. The scraper has a trapezoidal structure and has a vertical end and a bottom end. The vertical end is in contact with the inner wall of the inoculum box, and the bottom end is in contact with the bottom wall of the inoculum box.

[0013] Preferably, the driving component includes a rotating bearing disposed above the inoculum box, the inner ring of the rotating bearing being connected to a rotating handle, the rotating handle having a stepped structure.

[0014] The above technical solution has the following advantages or beneficial effects: 1. In this utility model, the second conveying pipe installed in the treatment box for dispensing microbial inoculum can achieve synchronous operation of dispensing and rotation with the help of a drive motor. The rotating second conveying pipe, together with the discharge hole opened on its outer wall, can form a 360° annular microbial distribution trajectory. During its rotation, it can disturb the surrounding sewage. During the release of microbial inoculum, it spreads along with the sewage flow to achieve more complete integration with the sewage, thereby avoiding the problems of excessively high or low local microbial inoculum concentration in traditional fixed pipes.

Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0025] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Example 1 like Figure 1 or Figure 4 As shown, this embodiment proposes a microbial addition device based on microbial water treatment, which includes a treatment tank 1 for containing sewage. A top cover 2 is detachably connected to the top of the treatment tank 1, and an inlet 3 is formed between the top opening of the treatment tank 1 and the top cover 2. A microbial inoculum box 4 for containing microbial inoculum is connected above the top cover 2. An inlet is provided above the microbial inoculum box 4. The microbial inoculum box 4 is connected to the top of the top cover 2, and a discharge port 5 is opened on its outer wall. A delivery pump 6 is also connected above the top cover 2. The input end of the delivery pump 6 is connected to the discharge port 5, and the output end is connected to a first delivery pipe 7. The first delivery pipe 7 has an inverted "L" shape. The other end of the first delivery pipe 7 passes through the top cover 2 and is placed inside the treatment tank 1. It also includes a second conveying pipe 8, with a discharge hole 9 on the outer wall of the second conveying pipe 8. The second conveying pipe 8 is horizontally and rotatably connected to the processing box 1, perpendicular to the first conveying pipe 7, and connected to the first conveying pipe 7. A drive motor 10 is provided on the side of the processing box 1. The output shaft of the drive motor 10 passes through the processing box 1 and is connected to the second conveying pipe 8 for transmission, so that the second conveying pipe 8 can rotate inside the processing box 1.

[0027] In the specific treatment process, the microbial inoculum in the inoculum tank 4 is pumped by the transfer pump 6 to the inside of the second transfer pipe 8 via the first transfer pipe 7. The inoculum enters the horizontally arranged second transfer pipe 8 and is released outward through the evenly distributed discharge holes 9 on its outer wall. At this time, the drive motor 10 drives the second transfer pipe 8 to rotate inside the treatment tank 1, so that the discharge holes 9 form a 360° annular microbial distribution trajectory, thereby avoiding the problems of excessively high or low local microbial concentrations in traditional fixed pipes. More importantly, the second transfer pipe 8 is not just a simple microbial carrier; during its rotation, it simultaneously disturbs the surrounding sewage, allowing the microbial inoculum to spread and diffuse with the sewage during release, achieving a more thorough integration with the sewage.

[0028] This integrated design, which combines directional transport, dynamic bacterial distribution, and synchronous agitation, allows microbial strains to be incorporated into wastewater in a uniform, efficient, and low-loss manner, significantly improving the treatment efficiency of pollutants.

[0029] In this embodiment, at least one set of stirring blades 11 are fixed to the outer wall of the second conveying pipe 8. The stirring blades 11 are designed to rotate synchronously with the second conveying pipe 8, and during the rotation, they can further enhance the disturbance effect on the sewage in the treatment tank 1, so that the bacteria can be more evenly distributed in the treatment tank 1.

[0030] refer to Figures 2 to 4 In this embodiment, a connecting pipe 12 is detachably connected to the bottom of the first conveying pipe 7. The connecting pipe 12 has an inverted "T" shape. Sealed bearings 13 are connected to the two connecting sections at the bottom of the connecting pipe 12. The outer ring of each sealed bearing 13 is connected to the inner wall of the connecting end, while the inner ring can rotate freely. A connecting cylinder 14 is connected between the inner rings of the two sealed bearings 13. A bacteria passage hole 15 is provided on the connecting cylinder 14, and the bacteria passage hole 15 communicates with the first conveying pipe 7. (Reference) Figure 5 The two ends of the connecting cylinder 14 are connected to the inner ring of the bearing via a connecting disc, so that a bacterial passage chamber 16 can be formed between the outer wall of the connecting cylinder 14 and the inner wall of the connecting pipe 12. The microbial community transported in the first conveying pipe 7 flows into the bacterial passage chamber 16, and the microbial community in the bacterial passage chamber 16 flows into the connecting cylinder 14 via the bacterial passage hole 15.

[0031] Furthermore, the second conveying pipe 8 includes a first pipe body 81 and a second pipe body 82, with one end of the first pipe body 81 and the other end of the second pipe body 82 being detachably connected to the inner ring of the sealed bearing 13. The first pipe body 81 is connected to the drive motor 10, thereby driving the inner rings of the two sealed bearings 13 connected thereto and the connecting cylinder 14 to rotate synchronously. The connecting cylinder 14 transmits power to the second pipe body 82 to further realize the rotation of the second pipe body 82.

[0032] Furthermore, a support frame 17 is fixed inside the processing box 1, and a bearing seat 18 is detachably connected to the support frame 17. The end of the second conveying pipe 8 away from the drive motor 10 (the tail end of the second pipe body 82) is connected to the inner ring of the bearing seat 18 to achieve support and rotation of the second conveying pipe 8.

[0033] The aforementioned detachable connection can be made by means of bolt connection or flange connection, and waterproof sealing treatment should be applied to the connection point.

[0034] In the above design, the connecting pipe 12 enables the dynamic and static connection between the first conveying pipe 7 and the second conveying pipe 8, allowing the second conveying pipe 8 to rotate while ensuring smooth flow of bacteria. This ensures that the bacteria are evenly released from the discharge holes 9 in the second conveying pipe 8. Specifically, after entering the connecting pipe 12 from the first conveying pipe 7, the bacteria first enter the bacterial passage chamber 16 between the outer wall of the connecting cylinder 14 and the inner wall of the connecting pipe 12, then enter the interior of the connecting cylinder 14 through the evenly distributed bacterial passage holes 15, and finally flow into the split-type second conveying pipe 8, thereby ensuring the stability and continuity of the flow of bacteria into the second conveying pipe 8.

[0035] On the other hand, the core components of this design, the first conveying pipe 7, the connecting pipe 12, and the second conveying pipe 8 (the first pipe body 81 and the second pipe body 82), are all detachable. If any of these components becomes clogged, they can be disassembled and cleaned separately without the need for overall replacement, thus reducing the cost of spare parts.

[0036] In this embodiment, a groove is provided on the top of the treatment tank 1, and the top cover 2 is detachably embedded and fixed into the groove by means of bolts or other components. The detachable structure of the top cover 2 allows the components on it to be disassembled for easy inspection and maintenance, and also exposes the interior of the treatment tank 1 for easy cleaning and other operations. A flip cover 19 for controlling the opening and closing of the water inlet 3 is hinged to the other side of the top cover 2. When closed, the flip cover 19 fits into the groove of the water inlet 3. During the treatment process, the water inlet 3 can be closed by flipping the flip cover 19, so that the interior of the treatment tank 1 forms a relatively closed space to prevent the internal sewage from flowing out due to disturbances or other factors during the treatment process.

[0037] Example 2 like Figure 1 or Figure 5 As shown, the other structures are the same as in Embodiment 1. The difference is that in this embodiment, several sets of support rods are connected between the bottom surface of the inoculum box 4 and the top cover 2, and the delivery pump 6 is connected between the bottom surface of the inoculum box 4 and the top cover 2. The support rods provide support, and the inoculum box 4 is connected at intervals above the top cover 2, which facilitates the placement of the delivery pump 6, so as to make reasonable space planning. At the same time, it can also provide a certain degree of protection for the delivery pump 6, avoiding damage to it from external impacts.

[0038] In this embodiment, a drive assembly is connected above the inoculum tank 4. The drive end of the drive assembly penetrates through the top surface of the inoculum tank 4 and is connected to an agitator for stirring the inside of the inoculum tank 4. The microbial inoculum is stored in the inoculum tank 4 in the form of liquid inoculum agent. If it remains stagnant for a long time, it is very easy for sedimentation or stratification to occur due to density differences. The mechanical stirring of the agitator is used to break the static state inside the inoculum tank 4, thereby ensuring that the concentration of inoculum inside the inoculum tank 4 remains consistent.

[0039] Furthermore, the aforementioned agitator includes a central rod 21 that is driveably connected to the drive end of the drive unit 20. A scraper 22 is connected to the outer wall of the central rod 21. The scraper 22 has a trapezoidal structure, with a vertical end and a bottom end. The vertical end is in contact with the inner wall of the inoculum box 4, and the bottom end is in contact with the bottom wall of the inoculum box 4. The trapezoidal structure of the scraper 22 allows the flowing microbial community to smoothly transition along the inclined surface, reducing frictional resistance between the community and the microbial community. The design of the scraper 22 also allows forcibly scraping off the microbial community attached to the inner wall of the inoculum box 4, allowing it to reintegrate into the inoculum box 4, ensuring that all microbial community can be extracted and utilized by the delivery pump 6, reducing microbial community loss.

[0040] In some embodiments, the aforementioned driving component 20 may be a servo motor, which is connected to the central rod 21 to drive the agitator. Considering that the servo motor is not used frequently, and the agitator is only activated to agitate the inside of the inoculum box 4 after it has been stationary for a long time, in order to save costs, in this embodiment, the driving component 20 includes a rotating bearing disposed above the inoculum box 4. The inner ring of the rotating bearing is connected to a handle, which has a stepped structure. The handle can be manually rotated by hand to drive the agitator to make the inoculum distribution in the inoculum box 4 more uniform.

[0041] In this embodiment, vertically arranged observation holes are provided on the outer wall of the inoculum tank 4. A transparent acrylic plate is fixed inside the observation holes, and a sealing measure is taken between the observation holes and the acrylic plate. Scale lines are provided on the side of the observation holes. The observation holes allow for further observation of the adhesion and volume information within the inoculum tank 4, enabling appropriate treatment and placement based on this information. Furthermore, during the inoculum introduction process, the current inoculum amount can be determined through the observation holes and scale lines, allowing for appropriate introduction based on the wastewater conditions in the treatment tank 1.

[0042] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
