Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an automatic stirring device for sedimentation tanks. Background Technology

[0002] Sedimentation tanks are devices used in wastewater treatment systems to remove suspended particles, settle solids, and separate liquids. They separate suspended solids and sediments from water through the principle of gravity settling. The agitator in the sedimentation tank is an important auxiliary device in wastewater treatment. Its main function is to prevent suspended matter from settling and forming a difficult-to-treat sediment layer, and to accelerate the collision and aggregation of suspended particles, thereby improving sedimentation efficiency and ensuring that the treated water quality meets the required standards. Therefore, the rational design and use of the agitator is of great significance for improving the performance of sedimentation tanks.

[0003] Current sedimentation tank mixing devices on the market typically employ a basic design, mainly consisting of components such as a motor, mixing blades, and support structures. They generally rely on external power supplies for operation. While this performs well in environments with ample and stable power supply, it can limit equipment operation in remote areas or under conditions of unstable power supply, thus affecting wastewater treatment efficiency.

[0004] To address the above problems, this utility model develops an energy-saving and intelligent automatic stirring device for sedimentation tanks. Utility Model Content

[0005] In order to overcome the shortcomings of existing sedimentation tank stirring devices, such as high energy consumption, low level of intelligence, and inability to adapt to unstable power environments, this utility model provides an energy-saving and intelligent automatic sedimentation tank stirring device.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: an automatic stirring device for a sedimentation tank, comprising a sedimentation tank body, a supporting horizontal plate at the top of the sedimentation tank body, a first motor symmetrically distributed at the top of the supporting horizontal plate, a stirring frame connected to the output shaft of the first motor, the stirring frame located within the sedimentation tank body, a water outlet pipe on one side of the sedimentation tank body, an electronic valve installed on the water outlet pipe, the working states of both the first motor and the electronic valve being regulated by a control system, a supporting frame fixed to the rear side of the sedimentation tank body, two solar panels installed at the top of the supporting frame, one of the solar panels having a surge arrester installed, a converter installed on the side of the supporting frame, and a storage battery installed at the rear side of the sedimentation tank body to power the first motor, electronic valve, and other equipment, with an overvoltage protector and an undervoltage protector installed on one side of the storage battery.

[0007] Furthermore, it is particularly preferred that the solar panels are arranged in a staggered manner.

[0008] Furthermore, it is particularly preferred that the sedimentation tank body is provided with symmetrically distributed fixing frames on the side away from the outlet pipe. One of the fixing frames is equipped with a second motor on its top, and a lead screw is connected to the output shaft of the second motor. The other fixing frame is provided with a guide rod and a connecting plate. A connecting plate is threaded onto the lead screw. A scraper for scraping and cleaning the sedimentation tank body is fixed between the two connecting plates.

[0009] Furthermore, it is particularly preferred that the size and shape of the scraper match the body of the sedimentation tank, and that the scraper slides up and down along the inner wall of the sedimentation tank body.

[0010] Furthermore, it is particularly preferred that the top of the supporting horizontal plate is fitted with symmetrically distributed isolation frames by hinge, the isolation frames cover the corresponding first motor, the front end of the isolation frames is then fastened to the supporting horizontal plate by bolts, the interior of the isolation frames is filled with sound insulation cotton, and a heat dissipation plate is embedded in the top of the isolation frames.

[0011] Furthermore, it is particularly preferred that the surface of the solar panel is covered with a foldable protective plate.

[0012] Furthermore, it is particularly preferred that the end of the bolt is fitted with a rubber sleeve.

[0013] Furthermore, it is particularly preferred that the sedimentation tank body is equipped with an observation plate.

[0014] Compared with the prior art, the present invention has the following technical effects: 1. The device is equipped with a power supply device consisting of a solar panel, a converter and a storage battery. It uses solar energy as the main energy source, which reduces the dependence on the external power grid and lowers the operating cost. The device can operate stably under various environmental conditions, without being limited by geographical location and power supply. It is suitable for sewage treatment scenarios of different scales and types. In addition, the integrated control system automatically controls the stirring and discharge process through preset programs, which reduces the need for manual intervention and improves the flexibility and convenience of the device.

[0015] 2. By installing a scraper device consisting of a fixed frame, a second motor, a lead screw, a guide rod, and a scraper on the sedimentation tank, the deposits on the tank wall can be effectively removed, keeping the sedimentation tank clean, extending the service life of the equipment, and ensuring the hygiene and safety of the treatment process.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, a further detailed description of this utility model will be provided below in conjunction with the accompanying drawings. It is hereby declared that any use of terms such as "up," "down," "left," "right," "front," "back," "inner," and "outer" in this document is based solely on the accompanying drawings and is not intended to limit the scope of this utility model.

[0024] Example 1: This example aims to address the problems of high energy consumption and low automation caused by the traditional sedimentation tank stirring device relying on external power supply and requiring manual switching to control the stirring time. Please refer to [link to relevant documentation]. Figures 1-4An automatic stirring device for a sedimentation tank includes a sedimentation tank body 1. Observation plates 23 are symmetrically distributed on the front side of the sedimentation tank body 1, allowing operators to visually inspect the working status of the sedimentation tank bottom. A support plate 2 is provided on the top of the sedimentation tank body 1, and a first motor 3, symmetrically distributed on the top of the support plate 2, is mounted on the top of the support plate 2. The first motor 3 is a DC motor, which has low energy consumption and is suitable for long-term continuous operation. A stirring frame 4 is connected to the output shaft of the first motor 3. The stirring frame 4 is located inside the sedimentation tank body 1 and is driven by the motor to rotate... To achieve the stirring function, a water outlet pipe 5 is provided on the left side of the sedimentation tank body 1 for discharging treated water. An electronic valve 6 is installed on the water outlet pipe 5. The working status of the first motor 3 and the electronic valve 6 is regulated by a control system 7, which is a programmable logic controller. The control system 7 controls the opening and closing of the first motor 3 and the electronic valve 6 by writing a program to ensure that the stirring process and drainage operation are executed according to the predetermined program. A support frame 8 is fixed to the rear side of the sedimentation tank body 1. Two solar panels 9 are installed on the top of the support frame 8 in a staggered manner to maximize the light absorption efficiency. One of the solar panels 9 is equipped with a surge arrester 901, which is connected to the ground to protect the solar panel 9 and its related electronic equipment from damage caused by lightning strikes and power surges. A converter 10 is installed on the right side of the support frame 8 to convert the alternating current generated by the solar panel 9 into direct current. A storage battery 11 is installed at the rear of the sedimentation tank body 1 to power the first motor 3, electronic valve 6, and other equipment. The storage battery 11 stores the electrical energy provided by the converter 10 and is connected to the first motor 3, electronic valve 6, and other equipment via cables to provide them with power support. The surface of the solar panel 9 is covered with a foldable protective plate to protect the solar panel 9 from the influence of the external environment. The foldable design allows the protective plate to be folded up when protection is not needed, ensuring that the solar panel 9 can be fully exposed to sunlight. An overvoltage protector 1101 and an undervoltage protector 1102 are installed on one side of the battery 11. The overvoltage protector 1101 is used to protect the battery 11 from voltage transients or continuous overvoltage damage. When the voltage of the battery 11 is lower than a set safety threshold, the undervoltage protector 1102 will take measures to protect the connected equipment from potential damage.

[0025] In practical applications, users can set the stirring time, speed, and opening time of the electronic valve 6 in the control system 7. When the set time is reached, the control system 7 will start the first motor 3 according to the preset program. The output shaft of the motor drives the stirring frame 4 to rotate inside the sedimentation tank, thereby achieving uniform stirring of the liquid in the tank. This process helps to promote the contact between suspended particles and sediments in the tank, enhance the collision and aggregation between particles, and thus improve the sedimentation efficiency. At the same time, continuous stirring can maintain the uniformity of water flow in the tank, prevent the formation of dead water zones, increase dissolved oxygen, improve biodegradation efficiency, and reduce the accumulation of sludge at the bottom. After the stirring operation is completed, the control system 7 will control the electronic valve 6 to open according to the preset program, so that the treated water can be discharged from the sedimentation tank through the outlet pipe 5, completing a complete treatment cycle. During the operation of the entire device, the solar panel 9 generates electricity by absorbing sunlight, which is converted from AC to DC by the converter 10 and then stored in the battery 11. The battery 11 then continuously supplies power to the first motor 3, electronic valve 6, and other components through cables, ensuring that the device can operate normally for a long time without sunlight or external power.

[0026] Example 2: Based on Example 1, please refer to... Figure 5 The sedimentation tank body 1 has symmetrically distributed fixing frames 12 on the side away from the outlet pipe 5. A second motor 13, a servo motor, is mounted on the top of the front fixing frame 12, enabling high-speed, high-precision position and speed control. A lead screw 14 is connected to the output shaft of the second motor 13. A guide rod 15 is provided on the rear fixing frame 12, and a connecting plate 1501 is slidably mounted on the guide rod 15. A connecting plate 1501 is threaded onto the lead screw 14. The connecting plate 1501 is "n" shaped, and a scraper 16 for scraping and cleaning the sedimentation tank body 1 is fixed between the two connecting plates 1501. The connecting plate 1501 can move horizontally along the guide rod 15 under the drive of the lead screw 14, so as to drive the scraper 16 to clean the tank wall of the sedimentation tank. Since the size and shape of the scraper 16 are matched with the sedimentation tank, it is ensured that the scraper 16 is in close contact with the tank wall of the sedimentation tank, effectively removing the attached substances and avoiding dead corners and residues.

[0027] After the treated water is discharged through the outlet pipe 5, the control system 7 starts the second motor 13 to clean the sedimentation tank according to the preset program. The output shaft of the second motor 13 drives the scraper 16 to descend along the guide rod 15 into the sedimentation tank through the lead screw 14. During the descent, the scraper 16 will stick to the tank wall to scrape off the impurities attached to the tank wall. After the scraper 16 completes one round trip, the attachments on the tank wall are completely removed, ensuring that the tank wall is clean and free of residue.

[0028] Please see Figure 6 The top of the supporting horizontal plate 2 is fitted with symmetrically distributed isolation frames 17 by hinges. The isolation frames 17 cover the corresponding first motor 3, effectively protecting the first motor 3 from the influence of the external environment. The front end of the isolation frame 17 is fastened to the supporting horizontal plate 2 by bolts 20 to ensure the stability of the isolation frame 17. The end of the bolt 20 is fitted with a rubber sleeve 22 to increase friction and facilitate personnel to rotate the bolt 20. The isolation frame 17 is filled with sound insulation cotton 18. A heat dissipation plate 19 is embedded in the top of the isolation frame 17. The sound insulation cotton 18 and the heat dissipation plate 19 can effectively reduce the noise of the motor during operation while ensuring that the motor works under good heat dissipation conditions, thus extending its service life.
