Description
Technical Field
[0001] This utility model belongs to the field of compound microbial strains for sewage treatment, specifically a compound microbial strain dosing device for sewage treatment. Background Technology
[0002] Compound microbial strains are designed specifically for wastewater biochemical treatment processes. They are specially formulated to enhance the degradation efficiency of pollutants such as organic matter, nitrogen, and phosphorus in wastewater through precise dosing. They are suitable for domestic sewage, industrial wastewater, and municipal sewage treatment scenarios. The core function of the dosing equipment is to realize the storage, activation, metered dosing, and uniform mixing of the microbial strains with the wastewater, thereby improving the treatment efficiency of the biochemical system.
[0003] In existing technologies, traditional dosing equipment uses a single stirring method when storing microbial inoculum. This monotonous stirring method can easily lead to dead zones in the stirring, causing the microbial inoculum to settle during storage. At the same time, employees cannot understand and adjust the internal environment of the microbial inoculum in a timely manner, resulting in the inactivation of the microbial inoculum. This, in turn, leads to increased production costs and reduced decontamination efficiency.
[0004] Therefore, this utility model provides a compound microbial inoculation device for sewage treatment. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A composite microbial inoculation device for sewage treatment, comprising a mixing tank, a fixed platform fixed to the top of the mixing tank, a fixed block fixed to the outer wall of the fixed platform, a first motor fixed to the upper surface of the fixed block, a first gear fixed to the output end of the first motor, a second gear meshing with the tooth end of the first gear, a lead screw fixed to the inside of the second gear, and a lifting block threaded to the outer wall of the lead screw. An inlet is fixed to the top of the mixing tank, and an outlet is fixed to the inside of the mixing tank. Through the above structure, the function of vertical movement is achieved by the cooperation of the lead screw and the lifting block, allowing the stirring height inside the mixing tank to be adjusted as needed. Compared with the fixed height of traditional devices, this provides greater flexibility, reduces stirring dead zones, improves mixing efficiency, and enhances the stability and operability of the device.
[0007] Preferably, a cooling shell is fixed to the outer wall of the mixing tank, an inlet is fixed to the inside of the cooling shell, a liquid pump is fixed to the end of the inlet away from the cooling shell, an outlet is fixed to the inside of the cooling shell, and the inside of the cooling shell is fixed to the outer wall of the outlet. Through the above structure, the structural characteristics of the cooling shell are used to achieve the function of rapidly reducing the internal temperature of the mixing tank. The gap reserved between the cooling shell and the mixing tank increases the contact area between the coolant and the surface of the mixing tank, so that the interior of the mixing tank can be cooled as a whole, improving the cooling efficiency, ensuring the activity of the bacteria inside the mixing tank, and improving the practicality and adaptability of the device.
[0008] Preferably, a second motor is fixedly connected to the lower surface of the lifting block, and a stirring shaft is fixedly connected to the output end of the second motor. Through the above structure, the function of mixing bacterial liquid is realized by the cooperation of the second motor and the stirring shaft, so that the bacterial strain can be fully absorbed and mixed with the nutrients and gases in the liquid when it is inside the mixing tank, ensuring the activity of the bacterial liquid inside the mixing tank, improving the activity of the bacterial strain, and improving the stability and practicality of the device.
[0009] Preferably, an air pump is fixedly connected to the top of the mixing tank, a guide tube is fixedly connected to the lower surface of the air pump, the outer wall of the guide tube is fixedly connected to the inside of the mixing tank, an air nozzle is fixedly connected to the bottom end of the guide tube, and an air outlet is fixedly connected to the upper surface of the mixing tank. Through the above structure, the guide tube enables the gas to be quickly replenished into the inside of the mixing tank and fully contacted with the inoculum, ensuring the activity of the inoculum. At the same time, the structural characteristics of the air nozzle allow the gas to be dispersed into dense bubbles when it is ejected from the air nozzle, expanding the contact area between the gas and the bacterial solution, enabling the inoculum to reproduce better, and improving the practicality and convenience of the device.
[0010] Preferably, the inner wall of the fixed platform is fixedly connected to a limiting post, and the outer wall of the limiting post is slidably connected to the inside of the lifting block. Through the above structure, the limiting post plays a role in limiting the lifting block, so that the lifting block remains stable during the up and down movement, thereby allowing the change of stirring height to be carried out normally and improving the stability of the device.
[0011] Preferably, a heating rod is fixed to the inner wall of the mixing tank; through the above structure, the heating rod realizes the function of rapidly heating the inside of the mixing tank. The temperature rise keeps the activity of the bacteria at the optimal level, improves the subsequent decontamination efficiency of the bacteria, reduces the risk of bacteria inactivation, and improves the stability and practicality of the device.
[0012] Preferably, a detection instrument is fixedly connected inside the mixing tank, and the outer wall of the detection instrument is fixedly connected inside the cooling shell. Through the above structure, the detection instrument realizes the function of dynamically detecting changes inside the mixing tank, and makes rapid adjustments according to the changes inside the mixing tank, so that the environment inside the mixing tank is conducive to the reproduction of bacteria, thereby improving the decontamination efficiency of bacteria, reducing decontamination costs, and improving the convenience and intuitiveness of the device.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. The wastewater treatment compound microbial inoculation device of this utility model, through the above structure, realizes the function of vertical movement by means of the cooperation of the lead screw and the lifting block, so that the stirring height inside the mixing tank can be adjusted as needed.

The wastewater treatment compound microbial inoculation device of this utility model, through the above structure, utilizes the structural characteristics of the cooling shell to achieve the function of rapidly reducing the internal temperature of the mixing tank. The gap reserved between the cooling shell and the mixing tank increases the contact area between the coolant and the surface of the mixing tank, enabling the interior of the mixing tank to be cooled as a whole, improving the cooling efficiency, ensuring the activity of the microbial inoculation inside the mixing tank, and improving the practicality and adaptability of the 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] like Figures 1 to 4 As shown in the embodiment of this utility model, a composite microbial inoculation device for sewage treatment includes a mixing tank 1. A fixed platform 11 is fixedly connected to the top of the mixing tank 1. A fixed block 12 is fixedly connected to the outer wall of the fixed platform 11. A first motor 13 is fixedly connected to the upper surface of the fixed block 12. A first gear 14 is fixedly connected to the output end of the first motor 13. A second gear 15 is meshed with the teeth of the first gear 14. A lead screw 16 is fixedly connected inside the second gear 15. A lifting block 17 is threadedly connected to the outer wall of the lead screw 16. An inlet 102 is fixedly connected to the top of the mixing tank 1, and an outlet 103 is fixedly connected inside the mixing tank 1. During operation, when it is necessary to change the height of the stirring position inside the mixing tank 1, the operator can start the first motor 13. The start of the first motor 13 drives the first gear 14 to rotate. When the screw 14 rotates, it drives the second gear 15, which is meshed with its teeth, to rotate. The rotation of the second gear 15 drives the lead screw 16 to rotate. When the lead screw 16 rotates, it drives the lifting block 17, which is threaded to its outer wall, to move. The up-and-down movement of the lifting block 17 causes the stirring position to move up and down. The mixing tank 1, the fixed platform 11, and the fixed block 12 provide overall support and fixation. The inlet 102 is used to add raw materials, and the outlet 103 is used to discharge raw materials. Through the above structure, the up-and-down movement function is achieved by the cooperation of the lead screw 16 and the lifting block 17. This allows the stirring height inside the mixing tank 1 to be adjusted as needed. Compared with the fixed height of traditional devices, this device has greater flexibility, reduces stirring dead zones, improves mixing efficiency, and enhances the stability and operability of the device.
[0025] like Figures 1 to 4As shown, a cooling shell 22 is fixed to the outer wall of the mixing tank 1. An inlet 21 is fixed to the inside of the cooling shell 22. A liquid pump 2 is fixed to the end of the inlet 21 away from the cooling shell 22. An outlet 23 is fixed to the inside of the cooling shell 22, and the inside of the cooling shell 22 is fixed to the outer wall of the outlet 103. During operation, when it is necessary to cool the inside of the mixing tank 1, the operator can start the liquid pump 2. The liquid pump 2 pumps coolant from the inlet 21 into the cooling shell 22. The coolant flows through the gap between the mixing tank 1 and the cooling shell 22. The liquid flows rapidly and exchanges heat with the temperature inside the mixing tank 1, quickly removing the heat from the mixing tank 1 before being discharged from the outlet 23. Through the above structure, the cooling shell 22 achieves the function of rapidly reducing the internal temperature of the mixing tank 1 by utilizing its structural characteristics. The gap reserved between the cooling shell 22 and the mixing tank 1 increases the contact area between the coolant and the surface of the mixing tank 1, enabling the entire interior of the mixing tank 1 to be cooled, improving the cooling efficiency, ensuring the activity of the bacteria inside the mixing tank 1, and improving the practicality and adaptability of the device.
[0026] like Figures 1 to 2 As shown, a second motor 3 is fixedly connected to the lower surface of the lifting block 17, and a stirring shaft 31 is fixedly connected to the output end of the second motor 3. During operation, when it is necessary to stir the bacterial liquid inside the mixing tank 1, the operator can start the second motor 3. The start of the second motor 3 drives the stirring shaft 31 to rotate. The stirring shaft 31 rotates rapidly to stir and mix the bacterial liquid inside the mixing tank 1, ensuring the activity of the bacterial liquid. Through the above structure, the function of mixing bacterial liquid is realized by the cooperation of the second motor 3 and the stirring shaft 31, so that the bacterial strain can be fully absorbed and mixed with the nutrients and gases in the liquid inside the mixing tank 1, ensuring the activity of the bacterial liquid inside the mixing tank 1, improving the activity of the bacterial strain, and improving the stability and practicality of the device.
[0027] like Figures 1 to 2 As shown, an air pump 4 is fixed to the top of the mixing tank 1, a guide tube 41 is fixed to the lower surface of the air pump 4, the outer wall of the guide tube 41 is fixed to the inside of the mixing tank 1, an air nozzle 42 is fixed to the bottom end of the guide tube 41, and an air outlet 43 is fixed to the upper surface of the mixing tank 1. During operation, when the bacterial solution inside the mixing tank 1 needs gas, the operator can start the air pump 4. The air pump 4 starts to pump gas from the guide tube 41 into the mixing tank 1, and finally to the air nozzle 42. The gas is sprayed out from the air nozzle 42 and disperses, mixing and contacting with the bacterial solution, ensuring the activity and reproduction requirements of the bacteria. Through the above structure, the guide tube 41 is used to quickly replenish the gas into the mixing tank 1 and make full contact with the bacteria, ensuring the activity of the bacteria. At the same time, the structural characteristics of the air nozzle 42 are used to make the gas dispersed into dense bubbles when it is sprayed out from the air nozzle 42, which expands the contact area between the gas and the bacterial solution, allowing the bacteria to reproduce better and improving the practicality and convenience of the device.
[0028] like Figures 1 to 2 As shown, a limiting post 101 is fixedly connected to the inner wall of the fixed platform 11, and the outer wall of the limiting post 101 is slidably connected to the inside of the lifting block 17. During operation, when the lifting block 17 moves up and down, it will always slide on the outer wall of the limiting post 101, thereby keeping the lifting block 17 at a stable angle and on a stable path during movement, so that the stirring operation can be carried out smoothly. Through the above structure, the limiting post 101 plays a role in limiting the lifting block 17, so that the lifting block 17 remains stable during up and down movement, thereby allowing the stirring height to be changed normally and improving the stability of the device.
[0029] like Figure 2 and Figure 4 As shown, a heating rod 501 is fixed to the inner wall of the mixing tank 1. During operation, when it is necessary to raise the temperature inside the mixing tank 1, the operator can activate the heating rod 501. Activation of the heating rod 501 will heat the liquid inside the mixing tank 1, thereby raising the temperature inside the mixing tank 1 and providing conditions for the activity and reproduction of the microorganisms. Through the above structure, the heating rod 501 achieves the function of rapidly raising the temperature inside the mixing tank 1. The increased temperature keeps the activity of the microorganisms at an optimal level, improves the subsequent decontamination efficiency of the microorganisms, reduces the risk of microorganism inactivation, and improves the stability and practicality of the device.
[0030] like Figures 1 to 3 As shown, a detection instrument 601 is fixedly connected inside the mixing tank 1, and the outer wall of the detection instrument 601 is fixedly connected inside the cooling shell 22. During operation, when various indicators inside the mixing tank 1 change, the operator can use the detection instrument 601 to observe the temperature and pH changes inside the mixing tank 1 in a timely manner, and then quickly adjust the environment inside the mixing tank 1 to maintain the activity of the bacteria. Through the above structure, the detection instrument 601 realizes the function of dynamically detecting changes inside the mixing tank 1, and quickly making adjustments according to the changes inside the mixing tank 1, so that the environment inside the mixing tank 1 is conducive to the reproduction of bacteria, thereby improving the decontamination efficiency of the bacteria, reducing the decontamination cost, and improving the convenience and intuitiveness of the device.
[0031] During operation, when it is necessary to change the height of the stirring position inside the mixing tank 1, the operator can start the first motor 13. The first motor 13 drives the first gear 14 to rotate. When the first gear 14 rotates, it drives the second gear 15, which is meshed with its teeth, to rotate. The rotation of the second gear 15 drives the lead screw 16 to rotate. When the lead screw 16 rotates, it drives the lifting block 17, which is threaded to its outer wall, to move. The up and down movement of the lifting block 17 causes the stirring position to move up and down. The mixing tank 1, the fixed platform 11, and the fixed block 12 provide overall support and fixation, while the feed inlet 102 is used to add raw materials. The discharge port 103 serves to discharge the raw materials. During operation, when it is necessary to cool the inside of the mixing tank 1, the operator can start the liquid pump 2. The liquid pump 2 pumps coolant from the inlet 21 into the cooling shell 22. The coolant flows rapidly in the gap between the mixing tank 1 and the cooling shell 22, exchanging heat with the temperature inside the mixing tank 1 and quickly removing heat before being discharged from the outlet 23. During operation, when it is necessary to stir the bacterial liquid inside the mixing tank 1, the operator can start the second motor 3. The second motor 3 drives the stirring shaft 31 to rotate. The stirring shaft 31 rotates rapidly to stir and mix the bacterial solution inside the mixing tank 1, ensuring the activity of the bacterial solution. During operation, when the bacterial solution inside the mixing tank 1 requires gas, the operator can start the air pump 4. The air pump 4 pumps gas from the guide pipe 41 into the mixing tank 1, ultimately reaching the air nozzle 42. The gas is ejected from the air nozzle 42 and mixes with the bacterial solution, ensuring the activity and reproduction needs of the bacteria. During operation, when the lifting block 17 moves up and down, it always slides against the outer wall of the limiting column 101, thus maintaining a stable angle and position during movement. The movement path ensures smooth mixing operations. During operation, when the temperature inside the mixing tank 1 needs to be raised, the operator can activate the heating rod 501. Activation of the heating rod 501 heats the liquid inside the mixing tank 1, thereby raising the temperature inside the mixing tank 1 and providing conditions for the activity and reproduction of the microorganisms. During operation, when various parameters inside the mixing tank 1 change, the operator can use the detection instrument 601 to promptly observe changes in temperature and pH inside the mixing tank 1, and then quickly adjust the internal environment of the mixing tank 1 to maintain the activity of the microorganisms.
