Description

Technical Field

[0001] This utility model relates to the field of flocculation and mixing technology, specifically to a flocculation mixer. Background Technology

[0002] In many fields such as industrial production and environmental protection, liquid flocculation is a key process.

[0003] Traditional flocculation mixers have gradually revealed many shortcomings in long-term use. In terms of mixing, the design of the mixing blades in the past was relatively simple, often only providing a simple mixing effect, making it difficult to efficiently disperse and mix the flocculant. Large flocculant particles or agglomerates could not be effectively broken up, resulting in insufficient flocculation reaction, poor mixing uniformity, and ultimately affecting the water quality of the treated liquid. In terms of equipment maintenance, the mixing device of traditional flocculation mixers usually adopts a relatively complex fixing method and is tightly connected to the tank. When it is necessary to clean, inspect or repair the mixing device, it often requires a lot of manpower, material resources and time. The disassembly process is cumbersome, requires professional tools and technicians, and is prone to damage to the equipment during disassembly. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a flocculation mixer, comprising: a tank structure; a stirring device slidably connected to the inner wall of the tank structure, the stirring device stirring the liquid within the tank structure by rotation; the stirring device includes a support plate, a rotating shaft rotatably connected to the inner wall of the top of the support plate, a first bushing fixedly connected to the outer wall of the rotating shaft, a porous blade fixedly connected to the outer wall of the first bushing, a second bushing fixedly connected to the outer wall of the rotating shaft, a serrated blade fixedly connected to the outer wall of the second bushing, a speed reducer fixedly connected to the outer wall of the top of the rotating shaft, a motor rotatably connected to the outer wall of the top of the speed reducer, a sliding rod slidably connected to the inner wall of the side of the support plate, a fixing block fixedly connected to the outer wall of the sliding rod, a pull plate fixedly connected to the outer wall of the sliding rod away from the fixing block, and a tension spring fixedly connected to the outer wall of the pull plate.

[0005] Preferably, the outer wall of the tension spring on the side away from the pull plate is fixedly connected to the outer wall of the support plate side, and the outer wall of the fixing block is slidably connected to the inner wall of the support plate side. Pulling the pull plate causes the slide rod to slide outward along the inner wall of the support plate side, simultaneously causing the fixing block to slide outward. Because the pull plate is far from the support plate, the tension spring is stretched and stores force. Releasing the pull plate causes the fixing block to reset through the action of the tension spring. The outer wall of the bottom of the reducer is fixedly connected to the outer wall of the top of the support plate. The porous blades and serrated blades are arranged in a ring array along the axis of rotation. The second bushing is located below the first bushing. When the motor starts, the power is reduced and increased in torque by the reducer rotatably connected to it, and then transmitted to the rotating shaft. The rotating shaft begins to rotate, and the first and second bushings fixed on the rotating shaft rotate accordingly, driving the porous blades and serrated blades to rotate.

[0006] Preferably, the tank structure includes a stirring tank, an inlet pipe is fixedly connected to the inner wall of the side of the stirring tank, an outlet pipe is fixedly connected to the inner wall of the stirring tank on the side away from the inlet pipe, a valve is fixedly connected to the outer wall of the outlet pipe, fixing grooves are symmetrically opened on the outer wall of the side of the stirring tank, and guide frames are symmetrically fixedly connected to the outer wall of the side of the stirring tank.

[0007] Preferably, the guide frame is located outside the fixed trough, the inside of the water inlet pipe is connected to the inside of the mixing tank, and the inside of the water outlet pipe is connected to the inside of the mixing tank. The liquid enters the mixing tank from the water inlet pipe in the tank structure. After the flocculation reaction is completed, the valve can be opened, and the treated liquid flows out of the mixing tank through the water outlet pipe to enter the subsequent processing steps.

[0008] Preferably, the inner wall of the side of the support plate is slidably connected to the outer wall of the mixing tank, the outer wall of the support plate is slidably connected to the inner wall of the guide frame, and the outer wall of the fixing block is slidably connected to the inner wall of the fixing groove. The support plate slides along the outer wall of the mixing tank under the guidance of the guide frame to avoid displacement of the installation position. During the downward sliding of the support plate, the inclined surface of the outer wall of the fixing block contacts the outer wall of the mixing tank. As it continues to move downward, the inclined surface of its outer wall causes the fixing block to be squeezed and slide outward along the inner wall of the support plate. At the same time, the slide rod also slides outward, causing the tension spring to be stretched and stored. When the support plate slides into place, the fixing block is aligned with the fixing groove. Through the action of the tension spring, the fixing block slides and locks into the fixing groove.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This utility model, by setting a rotating shaft, has an electric motor driving the rotating shaft to rotate through a reducer. This causes the porous blades and serrated blades on the first and second bushings to cooperate and perform different stirring functions. The serrated structure of the serrated blades can effectively disperse large flocculant particles or agglomerates, while the porous characteristics of the porous blades form local microcirculation, which works synergistically with the overall stirring flow field to greatly improve the uniformity of mixing, thereby significantly improving the flocculation effect and making the treated liquid water of better quality, meeting higher environmental protection or industrial production standards.

[0011] 2. This utility model, by setting a sliding rod and pulling the pull plate, achieves convenient installation and disassembly of the mixing device through the ingenious cooperation between the sliding rod, the fixing block and the tension spring. This facilitates comprehensive cleaning, inspection and maintenance of the mixing device, effectively reducing equipment downtime. At the same time, the automatic locking design of the fixing block and the fixing groove not only simplifies the installation steps, but also ensures the stability and reliability of the mixing device during operation.

The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art.

[0019] Example:

[0020] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a flocculation mixer, comprising: a tank structure 1; a stirring device 2 is slidably connected to the inner wall of the tank structure 1, the stirring device 2 stirring the liquid in the tank structure 1 by rotation; the stirring device 2 includes a support plate 21, a rotating shaft 22 is rotatably connected to the inner wall of the top of the support plate 21, a first bushing 23 is fixedly connected to the outer wall of the rotating shaft 22, a porous blade 24 is fixedly connected to the outer wall of the first bushing 23, a second bushing 25 is fixedly connected to the outer wall of the rotating shaft 22, a serrated blade 26 is fixedly connected to the outer wall of the second bushing 25, a reducer 28 is fixedly connected to the outer wall of the top of the rotating shaft 22, a motor 27 is slidably connected to the outer wall of the top of the reducer 28, a sliding rod 29 is slidably connected to the inner wall of the side of the support plate 21, a fixing block 291 is fixedly connected to the outer wall of the sliding rod 29, a pull plate 292 is fixedly connected to the outer wall of the sliding rod 29 away from the fixing block 291, and a tension spring 293 is fixedly connected to the outer wall of the pull plate 292.

[0021] The outer wall of the tension spring 293 on the side away from the pull plate 292 is fixedly connected to the outer wall of the side of the support plate 21. The outer wall of the fixing block 291 is slidably connected to the inner wall of the side of the support plate 21. Pulling the pull plate 292 causes the slide rod 29 to slide outward along the inner wall of the side of the support plate 21, simultaneously causing the fixing block 291 to slide outward. Because the pull plate 292 is away from the support plate 21, the tension spring 293 is stretched and stores force. Releasing the pull plate 292, through the action of the tension spring 293, causes the fixing block 291 to return to its original position, reducing the force. The outer wall of the bottom of the speed machine 28 is fixedly connected to the outer wall of the top of the support plate 21. The porous blades 24 and the serrated blades 26 are arranged in a ring along the central point of the rotating shaft 22. The second bushing 25 is located below the first bushing 23. When the motor 27 starts, the power is reduced and increased in torque by the reducer 28 connected to it, and then transmitted to the rotating shaft 22. The rotating shaft 22 starts to rotate, and the first bushing 23 and the second bushing 25 fixed on the rotating shaft 22 rotate accordingly, driving the porous blades 24 and the serrated blades 26 to rotate.

[0022] The tank structure 1 includes a mixing tank 11. An inlet pipe 12 is fixedly connected to the inner wall of the side of the mixing tank 11. An outlet pipe 13 is fixedly connected to the inner wall of the side of the mixing tank 11 away from the inlet pipe 12. A valve 14 is fixedly connected to the outer wall of the outlet pipe 13. Fixed grooves 15 are symmetrically opened on the outer wall of the side of the mixing tank 11. Guide frames 16 are symmetrically fixedly connected to the outer wall of the side of the mixing tank 11.

[0023] The guide frame 16 is set outside the fixed tank 15. The inside of the water inlet pipe 12 is connected to the inside of the mixing tank 11, and the inside of the water outlet pipe 13 is connected to the inside of the mixing tank 11. The liquid enters the mixing tank 11 from the water inlet pipe 12 in the tank structure 1. After the flocculation reaction is completed, the valve 14 can be opened, and the treated liquid flows out of the mixing tank 11 through the water outlet pipe 13 and enters the subsequent processing steps.

[0024] The inner wall of the side of the support plate 21 is slidably connected to the outer wall of the mixing tank 11, the outer wall of the support plate 21 is slidably connected to the inner wall of the guide frame 16, and the outer wall of the fixing block 291 is slidably connected to the inner wall of the fixing groove 15. The support plate 21 slides along the outer wall of the mixing tank 11 under the guidance of the guide frame 16 to avoid displacement of the installation position. During the downward sliding of the support plate 21, the inclined surface of the outer wall of the fixing block 291 contacts the outer wall of the mixing tank 11. As it continues to move downward, the inclined surface of its outer wall causes the fixing block 291 to be squeezed and slide outward along the inner wall of the support plate 21. At the same time, the slide rod 29 also slides outward, causing the tension spring 293 to be stretched and stored. When the support plate 21 slides into place, the fixing block 291 is aligned with the fixing groove 15. Through the action of the tension spring 293, the fixing block 291 slides and is inserted into the fixing groove 15.

[0025] Working principle: First, the liquid enters the mixing tank 11 through the inlet pipe 12 in the tank structure 1. Then, the agent is added from above the mixing tank 11. Next, the motor 27 on the stirring device 2 is started. The power is reduced and increased in torque by the reducer 28 connected to it and then transmitted to the rotating shaft 22. The rotating shaft 22 starts to rotate, and the first bushing 23 and the second bushing 25 fixed on the rotating shaft 22 rotate accordingly, driving the porous blade 24 and the serrated blade 26 to rotate. Since the porous blade 24 and the serrated blade 26 are tilted in opposite directions, as they rotate and stir, the agent that has settled at the bottom passes through the serrations on the edge of the serrated blade 26 during rotation. It generates additional shear and disturbance to the liquid, which can create stronger turbulence in local areas, breaking up large flocculant particles or agglomerates and promoting micro-mixing. At the same time, in conjunction with the porous structure of the porous blades 24, the liquid can partially penetrate into the interior of the blades during the stirring process, forming a local micro-circulation. This micro-circulation works in conjunction with the overall stirring flow field to help improve the uniformity of mixing, so that the different components in the liquid are fully mixed, and promote a more efficient flocculation reaction.

[0026] After the flocculation reaction is completed under the stirring action of the stirring device 2, the valve 14 can be opened, and the treated liquid flows out of the stirring tank 11 through the water outlet pipe 13 and enters the subsequent processing steps.

[0027] When maintenance and cleaning of the mixing device 2 are required, pull the pull plate 292 outward to make the slide rod 29 slide outward along the inner wall of the side of the support plate 21. At the same time, the fixing block 291 is separated from the fixing groove 15. Because the pull plate 292 is away from the support plate 21, the tension spring 293 is stretched and stored. Then, slide the support plate 21 out of the guide frame 16, and at the same time, drive the reducer 28 and the rotating shaft 22 out of the mixing tank 11. This completes the separation of the mixing device 2 from the tank structure 1, making it convenient to clean and maintain the mixing device 2. Conversely, when the mixing device 2 needs to be installed, slide the support plate 21 along the outer wall of the mixing tank 11. The guide frame 16 slides downward to prevent the installation position from shifting. As the support plate 21 slides downward, the inclined surface of the outer wall of the fixing block 291 contacts the outer wall of the mixing tank 11. As it continues to move downward, the inclined surface of its outer wall causes the fixing block 291 to be squeezed and slide outward along the inner wall of the support plate 21. At the same time, the slide rod 29 also slides outward, causing the tension spring 293 to be stretched and stored again. When the support plate 21 slides into place, the fixing block 291 is aligned with the fixing groove 15. Through the action of the tension spring 293, the fixing block 291 slides and is inserted into the fixing groove 15, thereby fixing the mixing device 2.
