Description

Technical Field

[0001] This utility model belongs to the field of biological pond flow regulation technology, specifically relating to a biological pond reflux liquid regulation device. Background Technology

[0002] Biological tanks in wastewater treatment refer to treatment facilities that utilize microorganisms to remove organic matter from wastewater; they are also known as activated tanks. Biological tanks effectively degrade organic matter in wastewater, reducing water pollution. Different types of biological tank systems may include various additional treatment facilities to improve water quality. In biological tank treatment with high concentrations of harmful substances, a recirculation device is usually required to reintroduce the purified wastewater into the biological tank, reducing its load and improving purification efficiency. However, this design has some limitations. First, the flow regulation method of a single pipeline cannot meet the flow distribution requirements of multiple pipelines at the same time, resulting in uneven distribution of the return liquid in the biological tank and affecting the biological treatment effect. Second, traditional devices lack an effective filtration structure, which can easily lead to impurities in the return liquid entering the biological tank, affecting the activity of microorganisms and treatment efficiency. In addition, traditional liquid level and flow monitoring methods are not precise enough and cannot monitor the changes in liquid level and flow of the return liquid in the biological tank in real time, thus failing to provide a reliable basis for starting and stopping the return pump and regulating the flow.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by setting up a reflux liquid regulating mechanism, can regulate the flow rate of two sets of pipes, ensuring the uniform distribution of reflux liquid in the biological tank. In traditional biological tank reflux liquid regulating devices, a single reflux pipe and regulating valve are usually used to control the flow rate of reflux liquid, which is difficult to meet the flow distribution requirements of multiple sets of pipes at the same time. This results in uneven distribution of reflux liquid in the biological tank, affecting the biological treatment effect. However, the reflux liquid regulating mechanism of this utility model, through the cooperation of the transmission component and the regulating component, can precisely control the rotation angle of the valve ball, thereby changing the relative position of through hole one and through hole two, realizing independent regulation of the flow rate of the two sets of pipes, so that the reflux liquid can be evenly distributed to different areas of the biological tank, improving the biological treatment efficiency and better meeting the requirements of the sewage treatment process.

[0015] 2. This utility model, by setting up a reflux liquid filtration mechanism, can effectively remove impurities in the reflux liquid, protect the activity of microorganisms, and improve treatment efficiency. Traditional devices lack an effective filtration structure, which easily leads to impurities in the reflux liquid entering the biological tank, affecting the activity of microorganisms and treatment efficiency. The filtration mechanism of this utility model includes a filter box, a filter plate, and a fixing component. The filter plate can be periodically removed for cleaning or replacement by pulling out the handle to ensure the filtration effect. At the same time, the design of the fixing component makes the installation and disassembly of the filter plate more convenient and quick, and the operation is simple and reliable. By pre-treating the reflux liquid through the filtration mechanism, impurities and suspended solids can be effectively removed, providing a better growth environment for microorganisms, thereby improving the treatment efficiency of the biological tank and the quality of the effluent.

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] Example 1 Please see Figure 1-7 The present invention provides the following technical solution: a biological pool reflux liquid regulating device, including a biological pool 1, a liquid extraction pipe 10 is provided on the side of the biological pool 1, a water pump 3 is provided at the other end of the liquid extraction pipe 10, a pipe 9 is provided at the other end of the water pump 3, a flow meter 4 is provided on the surface of the pipe 9, a diversion pipe 5 is provided at the other end of the pipe 9, a valve body 6 is provided at the other end of the diversion pipe 5, a pipe 7 is provided at the other end of the valve body 6, a reflux liquid regulating mechanism 8 is provided at the upper end of the valve body 6, and a filter mechanism 2 is provided at the connection between the liquid extraction pipe 10 and the biological pool 1. The reflux fluid regulating mechanism 8 includes a housing 81. The housing 81 is located at the upper end of the valve body 6. A transmission component 82 is located inside the housing 81. An regulating component 84 is located at the upper end of the transmission component 82. A valve ball 85 is located at the lower end of the transmission component 82 inside the valve body 6. A valve cavity 86 corresponding to the valve ball 85 is opened inside the valve body 6. A through hole 83 is opened inside the valve ball 85. A through hole 87 is opened on the side of the valve cavity 86.

[0019] Specifically, the transmission assembly 82 includes a rotating rod 821, which is rotatably connected to the center of the housing 81. A gear 822 is mounted on the upper surface of the rotating rod 821. Two sets of gears 823 are meshed with the side of gear 822. A rotating shaft 825 passes through the interior of each gear 823. A gear 824 is mounted on the lower surface of the rotating shaft 825. A gear 826 is meshed with the side of gear 824. A rotating shaft 827 passes through the interior of gear 826. The lower end of the rotating shaft 827 is fixedly connected to a valve ball 85. By adopting the above technical solution, the flow rate of the reflux liquid can be precisely adjusted. By rotating the rotating block 846, the rotating rod 821 is driven to rotate, which in turn drives the valve ball 85 to rotate through gear transmission, changing the relative position of through hole one 83 and through hole two 87, thereby adjusting the flow rate of the reflux liquid.

[0020] Specifically, the connection between the rotating shaft 827 and the housing 81 is rotatably connected via a bearing 828. By adopting the above technical solution, the friction between the rotating shaft 827 and the housing 81 can be reduced, thereby improving transmission efficiency and the service life of the device.

[0021] Specifically, the adjusting component 84 includes a rotating block 846, which is located at the upper end of the rotating rod 821. The rotating block 846 has anti-slip texture on its side. By adopting the above technical solution, it is easy for operators to manually rotate the rotating block 846, and the anti-slip texture can increase friction and prevent hand slippage.

[0022] Specifically, the adjusting assembly 84 also includes a circular groove 842. A circular groove 842 is formed inside the side of the rotating block 846. A limiting plate 843 is slidably connected inside the circular groove 842. A fixing rod 845 is provided at the lower end of the limiting plate 843, and a pull rod 848 is provided at the upper end of the limiting plate 843. A spring 841 is fitted inside the circular groove 842 on the surface of the pull rod 848. By adopting the above technical solution, the rotating block 846 can be fixed and released. When the flow rate needs to be adjusted, pull the pull ring 847 to disengage the fixing rod 845 from the fixing hole 844, and then rotate the rotating block 846 to adjust the flow rate. After the adjustment is completed, release the pull ring 847, the spring 841 returns to its original position, and the fixing rod 845 is inserted into the fixing hole 844 to fix the rotating block 846 and prevent it from moving accidentally due to external force.

[0023] Specifically, the upper end of the box 81 has multiple sets of fixing holes 844 corresponding to the fixing rod 845, and the upper end of the pull rod 848 is provided with a pull ring 847. By adopting the above technical solution, multiple fixing positions are provided for the fixing rod 845, and different flow adjustment angles can be selected for fixing according to actual needs, which improves the flexibility and adaptability of the device.

[0024] In this embodiment, the start, stop and speed of the water pump 3 are controlled by the controller 24 according to the liquid level in the biological tank 1 and the flow rate requirement of the return liquid, thereby adjusting the pumping volume of the pumping pipe 10. Then, by rotating the rotating block 846 in the return liquid adjustment mechanism 8, the valve ball 85 is driven to rotate by the transmission component 82, changing the relative position of the through hole 1 83 and the through hole 2 87, thereby adjusting the flow rate of the return liquid to meet the treatment requirements of the biological tank 1. At the same time, the flow meter 4 can monitor the flow rate in the pipe 1 9 in real time and feed the data back to the controller 24 for further precise control.

[0025] Example 2 The difference between this embodiment and embodiment 1 is that: the filtration mechanism 2 includes a filter box 27, the filter box 27 is located at the center of the liquid extraction tube 10, a filter plate 21 is slidably connected inside the filter box 27, a handle 22 is provided at the upper end of the filter plate 21, a mounting block 28 is provided at the upper side of the filter box 27, a fixing component 26 is provided inside the mounting block 28, and a locking hole 25 is provided at the upper side of the filter plate 21. By adopting the above technical solution, impurities in the reflux liquid can be effectively filtered to prevent impurities from entering the biological tank 1 and affecting the activity and treatment efficiency of microorganisms. The filter plate 21 can be periodically removed by the handle 22 for cleaning or replacement to ensure the filtration effect.

[0026] Specifically, the filtration mechanism 2 also includes a controller 24, which is located at the side corner of the biological tank 1, and a level gauge 23 is installed on the inner wall of the biological tank 1. By adopting the above technical solution, the level gauge 23 can monitor the changes in the liquid level in the biological tank 1 in real time and transmit the data to the controller 24. The controller 24 automatically controls the operation of the water pump 3 based on the liquid level and flow data, thereby realizing intelligent control and improving the operating efficiency and stability of the system.

[0027] Specifically, the fixing component 26 includes a second spring 261, which is installed inside the mounting block 28, and a locking rod 262 is provided at the other end of the second spring 261. By adopting the above technical solution, the filter plate 21 can be fixed and released. When it is necessary to clean or replace the filter plate 21, press the locking rod 262 to disengage the locking rod 262 from the locking hole 25, and the filter plate 21 can be pulled out. During installation, insert the filter plate 21 into the filter box 27, release the locking rod 262, and the spring 261 will return to its original position, so that the locking rod 262 is inserted into the locking hole 25 to fix the filter plate 21. The operation is simple and convenient.

[0028] Specifically, the fixing component 26 also includes a slider 263, the upper end of the locking rod 262 is provided with a slider 263, and the upper end of the mounting block 28 is provided with a corresponding groove 264. By adopting the above technical solution, the cooperation between the slider 263 and the groove 264 can make the lever 262 more stable during the pressing process, thereby improving the reliability and stability of the operation.

[0029] In this embodiment, the reflux liquid first passes through the filter plate 21 in the filter mechanism 2 to remove impurities, and then enters the suction pipe 10, where it is pumped by the water pump 3 to the biological tank 1 for reflux treatment. When it is necessary to clean or replace the filter plate 21, press the lever 262 to pull out the filter plate 21 for operation. After the operation is completed, reinsert the filter plate 21 into the filter box 27, release the lever 262 to fix it. At the same time, the controller 24 automatically controls the operation of the water pump 3 according to the data of the level gauge 23 and the flow meter 4 to ensure that the liquid level and reflux liquid flow rate in the biological tank 1 are stable within the set range, thereby achieving an efficient and stable sewage treatment process.

[0030] The working principle and usage process of this utility model are as follows: In use, firstly, based on the liquid level in the biological tank 1 and the required flow rate of the return liquid, the controller 24 controls the start / stop and speed of the water pump 3, thereby adjusting the pumping volume of the extraction pipe 10. Then, by rotating the rotating block 846 in the return liquid adjustment mechanism 8, the transmission component 82 drives the valve ball 85 to rotate, changing the relative position of through hole one 83 and through hole two 87, thus adjusting the flow rate of the return liquid to meet the treatment requirements of the biological tank 1. Simultaneously, the flow meter 4 can monitor the flow rate in pipe one 9 in real time and feed the data back to the controller 24 for further precise control. The reflux liquid first passes through the filter plate 21 in the filtration mechanism 2 to remove impurities, and then enters the suction pipe 10, where it is pumped by the water pump 3 to the biological tank 1 for reflux treatment. When it is necessary to clean or replace the filter plate 21, press the lever 262 to pull out the filter plate 21 for operation. After the operation is completed, insert the filter plate 21 back into the filter box 27 and release the lever 262 to fix it. At the same time, the controller 24 automatically controls the operation of the water pump 3 according to the data of the level gauge 23 and the flow meter 4 to ensure that the liquid level and reflux liquid flow rate in the biological tank 1 are stable within the set range, so as to achieve an efficient and stable sewage treatment process.
