Description

Technical Field

[0001] This invention relates to the field of stirring device technology, and in particular to a dynamic and efficient submersible stirring device for biological ponds. Background Technology

[0002] In the field of wastewater treatment, fixed submersible mixers are commonly used in biological tanks to complete the mixing operation. These devices are installed at specific locations in the biological tank via fixed supports and rely on the rotation of their own impellers to achieve mixing in localized areas. However, existing stationary submersible mixing devices have many insurmountable drawbacks in practical applications: First, the mixing coverage of a single agitator can only cover a local area, and the mixing range is limited by the equipment installation location. In order to avoid mixing dead zones in the biological tank and prevent sludge settling and accumulation, multiple agitators need to be installed in the tank, which not only significantly increases the equipment procurement cost and installation cost, but also leads to high energy consumption in the later operation.

[0003] Secondly, the fixed installation method prevents the agitator from stirring the corner areas of the biological tank, which can easily lead to localized stirring dead zones (such as the four corners of commonly used rectangular biological tanks), affecting the overall biochemical reaction efficiency and failing to achieve the expected treatment effect.

[0004] Furthermore, equipment maintenance is difficult and costly. Because the mixer is constantly in a humid environment and subjected to dynamic load reactions during operation, problems such as bolt corrosion and component detachment can occur, requiring regular inspection and maintenance. When inspection, maintenance, or troubleshooting is needed, it must be lifted out of the water using a fixed steel structure and auxiliary equipment such as a cantilever crane. This process is time-consuming and poses significant safety hazards. In addition, traditional stationary submersible mixers are mostly single-impeller structures, which have limited mixing intensity and coverage. With the increasing demand for wastewater treatment, the problem of insufficient mixing efficiency has gradually become apparent. Summary of the Invention

[0005] To address the above problems, this invention proposes a dynamic and efficient submersible mixing device for biological ponds. The technical solution used is as follows: A dynamic and efficient submersible mixing device for a biological pond includes a support track, a walking device, an attitude adjustment device, a lifting device, and a dual-impeller submersible mixer. The support track is disposed on the biological pond, and the walking device is disposed on the support track and is capable of moving on the support track. The attitude adjustment device includes a mounting frame rotatably mounted on the walking device, and the dual-impeller submersible mixer is rotatably mounted on the mounting frame. The lifting device includes a base mounted on the biological pond, a rotating frame rotatably mounted on the base, a lifting frame slidably mounted on the rotating frame, and a connecting track fixedly mounted on the lifting frame. The walking device intermittently enters the connecting track.

[0006] Because the present invention adopts the above-described technical solution, the present invention has the following advantages: 1. This invention, through the coordinated design of a support track walking device and an attitude adjustment device, enables the movement and rotation of a double-impeller submersible mixer in a biological tank. At the end of the biological tank, the double-impeller submersible mixer can rotate autonomously to its maximum tilt angle and then return to a horizontal state while rotating with the mounting frame. This breaks through the installation position limitations of traditional fixed mixers, and can not only cover the main area of ​​the biological tank, but also accurately reach the corners and blind spots that traditional devices cannot cover, such as the four corners of rectangular tanks, effectively eliminating stirring dead angles. At the same time, the double-impeller structure provides higher stirring intensity than the traditional single impeller.

[0007] 2. This invention significantly reduces equipment and operating costs. A single device can achieve efficient mixing of the entire biological tank, eliminating the need for multiple mixers to compensate for insufficient coverage, as is the case with traditional fixed equipment. This reduces the number of equipment to be purchased and lowers the initial equipment investment and installation costs.

[0008] 3. The lifting device of the present invention, through the coordinated design of the base, rotating frame and lifting frame, can quickly lift the double impeller submersible mixer from underwater to a safe working height, without relying on complex auxiliary equipment such as fixed steel structures and cantilever cranes, making maintenance convenient and safe, and reducing operation and maintenance costs.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention. Example:

[0027] A dynamic and efficient submersible mixing device for biological ponds, such as Figures 1-4 As shown, it includes a support rail 1, a walking device 2, an attitude adjustment device 3, a lifting device 4, and a double-impeller submersible mixer 5; a crossbeam frame 102 is fixedly installed on the support rail 1 and is fixedly installed on the biological pool 6 through the crossbeam frame 102; the walking device 2 is set on the support rail 1 and can walk on the support rail 1; specifically, the support rail 1 can be made of I-beam, and the walking device 2 walks on the lower flange of the I-beam; the attitude adjustment device 3 is installed on the walking device 2, and the double-impeller submersible mixer 5 is installed at the end of the attitude adjustment device 3; the lifting device 4 is set on the side of the biological pool 6.

[0028] like Figures 5-8 As shown, the traveling device 2 includes a sliding frame 201 and traveling rollers 202. The sliding frame 201 slides on the support rail 1, and the traveling rollers 202 are rotatably mounted on the sliding frame 201 and roll on the support rail 1. Specifically, in this embodiment, there are two pairs of traveling rollers 202. The two traveling rollers 202 in each pair are respectively arranged on both sides of the web of the I-beam and roll on the lower flange. The traveling rollers 202 in the same pair are driven to rotate synchronously by a traveling drive motor 203.

[0029] In one specific implementation of this embodiment, the walking drive motor 203 is fixedly mounted on the sliding frame 201, and its output end drives two walking rollers 202 to rotate synchronously through a transmission assembly. The transmission assembly includes a transmission wheel one, a transmission wheel two, a transmission wheel three, and a transmission wheel four. Each walking roller 202 is coaxially fixedly mounted with a transmission wheel one, and the output end of the walking drive motor 203 is coaxially fixedly mounted with a transmission wheel four. The transmission wheel one is synchronously connected to the transmission wheel two through a transmission belt, and the transmission wheel four is synchronously connected to the transmission wheel three through a transmission belt. The transmission wheel two and the transmission wheel three are coaxially fixedly connected together.

[0030] The sliding frame 201 also has a clamping wheel 204 rotatably mounted inside. The clamping wheel 204 can roll on the support rail 1, and a cleaning plate 2041 is fixedly mounted on the clamping wheel 204. Specifically, the clamping wheel 204 is an I-beam wheel and rolls on the lower flange of the I-beam. Several cleaning plates 2041 are evenly distributed circumferentially on the wheel disc of the I-beam wheel for cleaning debris when the wheel rotates. Furthermore, the clamping wheels 204 are arranged in pairs and are rotatably mounted on the mounting base. The mounting bases of the same pair are elastically connected by a connecting spring 205.

[0031] Distance sensors 207 are installed at both ends of the sliding frame 201 to detect the distance between the sliding frame 201 and the wall of the biological tank 6. Indicator lights 206 are also installed on the sliding frame 201 to allow operators to quickly confirm whether the dual-impeller submersible mixer 5 is in normal working condition. Specifically, a green light indicates that the dual-impeller submersible mixer 5 is operating stably and without faults, while a red light serves as a fault alarm signal, directly indicating that the dual-impeller submersible mixer 5 is malfunctioning and cannot operate normally. In such cases, immediate shutdown for inspection and repair is necessary to prevent the fault from escalating.

[0032] like Figures 9-12As shown, the attitude adjustment device 3 includes a mounting frame 301, the top of which is rotatably mounted on the sliding frame 201, and the double impeller submersible mixer 5 is rotatably mounted on the bottom of the mounting frame 301 (which can be mounted by a rotating shaft). Specifically, an adjusting motor 302 is fixedly installed on the sliding frame 201. A transmission shaft 306 is coaxially fixedly installed on the output end of the adjusting motor 302. The transmission shaft 306 is rotatably installed inside the mounting frame 301, and a central gear 303 is coaxially fixedly installed on the transmission shaft 306. An internal gear ring 305 is fixedly installed at the top of the mounting frame 301. A transition gear 304 is provided between the central gear 303 and the internal gear ring 305. The transition gear 304 is rotatably installed on the sliding frame 201 and meshes with the central gear 303 and the internal gear ring 305. A linkage rod 309 is vertically slidably installed inside the mounting frame 301. A linkage rack 310 is fixedly installed on the linkage rod 309. A linkage ring 311 is coaxially fixedly installed on the rotating shaft of the double impeller submersible mixer 5. The linkage rack 310 and the linkage ring 311 mesh with each other. A special-shaped wheel 307 and a power transmission component 308 are provided between the transmission shaft 306 and the linkage rod 309.

[0033] The irregularly shaped wheel 307 is semi-circular in shape, rotatably mounted on the mounting bracket 301 at its center. A groove is provided on the outer periphery of the irregularly shaped wheel 307, and the top end of the linkage rod 309 is slidably mounted within this groove. The power transmission assembly 308 includes an input bevel gear 3081, an output bevel gear 3082, an input gear 3083, and an output gear 3084. The input bevel gear 3081 is coaxially fixedly mounted on the transmission shaft 306 and meshes with the output bevel gear 3082. The output gear 3084 is coaxially fixedly mounted on the irregularly shaped wheel 307 and meshes with the input gear 3083. The output bevel gear 3082 and the input gear 3083 are coaxially fixedly mounted together and rotatably mounted on the mounting bracket 301. When the transmission shaft 306 rotates, the input bevel gear 3081 rotates synchronously, driving the output gear 3084 to rotate via the output bevel gear 3082 and the input gear 3083, thereby driving the irregularly shaped wheel 307 to rotate.

[0034] The rotation of the irregular wheel 307 causes the linkage rod 309 to move, and the linkage rack 310 moves with the linkage rod 309, causing the linkage gear ring 311 to rotate, thereby driving the double impeller submersible mixer 5 to rotate. Specifically, when the linkage rod 309 gradually slides from the arc edge to the center of the straight edge relative to the irregular wheel 307, the linkage rod 309 moves upward; when it gradually slides from the center of the straight edge to the arc edge, the linkage rod 309 moves downward; when the linkage rod 309 is at the center of the straight edge, the double impeller submersible mixer 5 remains horizontal; when the linkage rod 309 slides on the arc edge, the linkage rod 309 no longer moves vertically, and the double impeller submersible mixer 5 tilts to its maximum angle.

[0035] Because the drive shaft 306 is relatively long, in order to ensure the stability of the drive shaft 306, a support ring 3061 is provided on the shaft body of the drive shaft 306. The support ring 3061 is fixedly installed inside the mounting bracket 301, and the drive shaft 306 is rotatably connected to the support ring 3061.

[0036] like Figures 13-15 As shown, the lifting device 4 includes a lifting frame 401, a connecting rail 402, a rotating frame 404, and a base 407. The base 407 is fixedly installed on the side of the biological tank 6, the rotating frame 404 is rotatably installed on the base 407, the lifting frame 401 is vertically slidably installed on the rotating frame 404, and the connecting rail 402 is fixedly installed on the lifting frame 401. A limiting strip 101 is fixedly provided at the end of the supporting rail 1, and a connecting groove 4021 is provided on the connecting rail 402 corresponding to the limiting strip 101. When the limiting strip 101 is inserted into the connecting groove 4021, the connecting rail 402 is relatively fixed to the supporting rail 1.

[0037] A lifting screw 403 is installed on the rotating frame 404. The lifting screw 403 is driven to rotate by a motor. The lifting frame 401 is threadedly connected to the lifting screw 403.

[0038] A rotary motor 408 is fixedly mounted on the base 407. An input gear 409 is coaxially fixedly mounted on the output end of the rotary motor 408. An output gear ring 410 is fixedly mounted on the rotating frame 404. The output gear ring 410 meshes with the input gear 409. When the rotary motor 408 drives the input gear 409 to rotate, the output gear ring 410 rotates accordingly, thereby driving the rotating frame 404 to rotate.

[0039] The rotating frame 404 is provided with a limiting hole 4041. A locking rod 405 is slidably installed on the base 407 corresponding to the limiting hole 4041. Each locking rod 405 corresponds to a drive cylinder 406 installed on the base 407. The output end of the drive cylinder 406 is fixedly connected to the corresponding locking rod 405. When the drive cylinder 406 drives the locking rod 405 to move and insert into the limiting hole 4041, the rotating frame 404 stops rotating.

[0040] The working principle of this embodiment is as follows: When stirring, the walking drive motor 203 is started, and the walking roller 202 rolls on the support rail 1, so that the walking device 2 drives the attitude adjustment device 3 and the double impeller submersible mixer 5 to move in the biological tank 6. The double impeller submersible mixer 5 starts (the double impeller submersible mixer 5 is kept horizontal), the impellers on both sides rotate, the sewage flows, and under the reflection of the tank wall, a circulating water flow is formed to achieve a more uniform mixing effect.

[0041] During the movement, the clamping wheel 204 rolls on the support rail 1, and the cleaning plate 2041 sweeps away debris along the way.

[0042] When the equipment moves to the end of the biological tank 6, the adjusting motor 302 is activated, the drive shaft 306 rotates, the central gear 303 drives the transition gear 304 to rotate, and the transition gear 304 drives the internal gear ring 305 to rotate, thereby causing the mounting frame 301 to rotate. Simultaneously, the rotation of the drive shaft 306 drives the shaped wheel 307 to rotate via the power transmission assembly 308. The linkage rod 309 slides one revolution relative to the shaped wheel 307, causing the double-impeller submersible mixer 5 to rotate to its maximum tilt angle while rotating with the mounting frame 301, and then return to a horizontal state. During this process, the tilted double-impeller submersible mixer 5, rotating with the mounting frame 301, can precisely cover the corner areas of the biological tank 6, achieving effective mixing without dead angles. After the corner areas are mixed, the equipment rotates in the opposite direction to its initial state.

[0043] If the dual-impeller submersible mixer 5 malfunctions, indicator light 206 will illuminate red. The traveling device 2 moves to the connecting rail 402, and the lifting screw 403 drives the lifting frame 401 upwards. The traveling device 2, the attitude adjustment device 3, and the dual-impeller submersible mixer 5 are all lifted. The rotary motor 408 drives the rotating frame 404 to rotate 180°, and the drive cylinder 406 drives the locking rod 405 to extend into the limiting hole 4041, fixing the rotating frame 404. Maintenance work on the dual-impeller submersible mixer 5 then begins. After maintenance, the traveling device 2 moves to the support rail 1 to perform mixing operations.
