Description

Technical Field

[0001] This utility model is a wastewater mixing device for coal chemical industry, belonging to the field of coal chemical wastewater treatment equipment. Background Technology

[0002] Coal chemical production processes inevitably generate coal chemical wastewater containing suspended solids to varying degrees. The suspended solids in the coal chemical wastewater need to be treated by adding flocculants. With the combined action of both, the particle size of the suspended solids will be further increased. Then, this industrial wastewater containing large particles, after being mixed, flows directly from the wastewater surface inside the cylinder into the next-stage sedimentation tank for sedimentation treatment. The mixing of the two requires the use of a stirring device.

[0003] In the existing technology, baffles are installed on both sides of the inner wall of the mixing tank to turbulent the vortex formed by mixing. However, the baffles can only turbulent the edge of the mixing area, so that the vortex generated in the mixing center cannot be turbulent. The generation of vortices affects the mixing effect between wastewater and chemical agents, thereby reducing the efficiency of coal chemical wastewater treatment.

[0004] In summary, this utility model provides a wastewater mixing device for coal chemical industry to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wastewater mixing device for coal chemical industry, so as to solve the problem of reduced mixing effect caused by the small anti-swirl area mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater mixing device for coal chemical industry, comprising a mixing tank, a support platform penetrating the center of the top of the mixing tank, a servo motor fixedly connected to one side of the top of the mixing tank, a driven wheel sleeved on the outside of the support platform and directly above the mixing tank, a driving wheel fixedly connected to the output end of the servo motor and above the driven wheel, a mixing tube penetrating between the top and bottom of the support platform, an installation ring rotatably sleeved on the upper part of the inner wall of the mixing tank, a ring gear fixedly connected to the top of the inner wall of the mixing tank and above the installation ring, the bottom end of the support platform sequentially penetrating the ring gear and the installation ring and extending below the installation ring, a partition rotatably connected inside the mixing tank and directly below the installation ring, and a longitudinal turbulence-disrupting component fixedly connected between the two sides of the inner wall of the installation ring and the two sides of the support platform, the bottom of the longitudinal turbulence-disrupting component penetrating the partition and extending below the partition.

[0007] Furthermore, the bottom end of the stirring tube passes through the partition and extends directly below the partition. Multiple stirring rods are uniformly fixedly connected from bottom to top on both sides of the stirring tube surface and below the partition.

[0008] Furthermore, drainage holes are provided on both sides of the stirring tube and between every two stirring rods, and the stirring tube is fixedly connected to the partition.

[0009] Furthermore, a support frame is fixedly connected to the bottom of the mixing tank, and a drain pipe is connected to the bottom of one side of the mixing tank.

[0010] Furthermore, a water inlet pipe is connected to the top of the other side of the mixing tank and below the partition, and an infusion pipe is rotatably connected to the top of the mixing tube.

[0011] Furthermore, the longitudinal turbulence-disrupting assembly includes two transmission rods, which are rotatably connected to both sides of the inner wall of the mounting ring. The opposite ends of the two transmission rods extend to both sides of the support platform. The sides of the two transmission rods that are separated from each other are bent and protruding. Movable sleeves are rotatably fitted at the bent parts of the two transmission rods. Connecting rods are fixedly connected to the bottom of the two movable sleeves. Connecting seats are hinged to the bottom ends of the two connecting rods. A turbulence-disrupting plate is provided between the bottoms of the two connecting seats. Transmission wheels are fixedly fitted on both sides of the rod surfaces of the two transmission rods and on both sides of the bottom of the annular gear ring.

[0012] Furthermore, the bottom of the annular gear ring is uniformly and fixedly connected with multiple teeth, and the annular gear ring meshes with two transmission wheels.

[0013] The beneficial effects of this utility model are:

[0014] The servo motor drives the stirring tube and stirring rod to stir the wastewater inside the mixing tank. At the same time, the ring gear ring and the longitudinal turbulence component drive the turbulence plate inside the longitudinal turbulence component to move up and down and tilt, which turbulences generated during the stirring of wastewater inside the mixing tank, effectively improving the mixing and homogenization effect of coal chemical wastewater.

[0015] While the longitudinal turbulence-inducing components are rotated by the support platform, the meshing action between the external gear ring and the transmission wheel drives the turbulence plate to move up and down and tilt to perform turbulence work. There is no need for a separate motor to drive the turbulence, which reduces the use of motor units and effectively saves the operating cost of the coal chemical wastewater mixing device.

[0016] Open the valve on the inlet pipe to deliver wastewater into the mixing tank. Start the servo motor to drive the drive wheel to rotate. The drive wheel drives the driven wheel to rotate, which in turn drives the support platform to rotate. The support platform drives the mixing tube, mixing rod, and longitudinal turbulence components to stir the wastewater inside the mixing tank. At the same time, the wastewater treatment catalyst is delivered to the mixing tube through the delivery pipe, and the catalyst is delivered to different depths of wastewater inside the mixing tank through the drain holes on the surface of the mixing tube, achieving the effect of uniform catalyst delivery.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-5This utility model provides a technical solution: a wastewater mixing device for coal chemical industry, including a mixing tank 1, with a support platform 2 penetrating through the center of the top of the mixing tank 1. A servo motor 3 is fixedly connected to one side of the top of the mixing tank 1. The servo motor 3 is connected to an external power supply and is equipped with a power control switch. A driven wheel 5 is sleeved on the outside of the support platform 2 and directly above the mixing tank 1. A driving wheel 4 is fixedly connected to the output end of the servo motor 3 and on top of the driven wheel 5. The driving wheel 4 meshes with the driven wheel 5. The support platform 2 is rotatably connected to the mixing tank 1. The top and bottom of the support platform 2 are connected... A stirring tube 6 runs through the middle of the mixing tank 1. An installation ring 16 is rotatably fitted on the upper part of the inner wall of the mixing tank 1. A ring gear 9 is fixedly connected to the top of the inner wall of the mixing tank 1 and above the installation ring 16. The bottom end of the support platform 2 passes through the ring gear 9 and the installation ring 16 in sequence and extends to the bottom of the installation ring 16. A partition 7 is rotatably connected inside the mixing tank 1 and directly below the installation ring 16. A longitudinal turbulence component 8 is fixedly connected between the two sides of the inner wall of the installation ring 16 and the two sides of the support platform 2. The bottom of the longitudinal turbulence component 8 passes through the partition 7 and extends to the bottom of the partition 7.

[0026] Please see Figure 3-5 The bottom end of the stirring tube 6 passes through the partition 7 and extends directly below the partition 7. Multiple stirring rods 12 are evenly fixedly connected from bottom to top on both sides of the stirring tube 6 and below the partition 7. Drainage holes 11 are opened on both sides of the stirring tube 6 and between every two stirring rods 12. The stirring tube 6 is fixedly connected to the partition 7. The bottom end of the stirring tube 6 is connected to the inside of the stirring tank 1. The partition 7 can block the coal chemical wastewater inside the stirring tank 1 and prevent the parts above the partition 7 from being contaminated by the wastewater.

[0027] Please see Figure 3-5 A support frame 15 is fixedly connected to the bottom of the mixing tank 1. A drain pipe 14 is connected to the bottom of one side of the mixing tank 1. A water inlet pipe 13 is connected to the top of the other side of the mixing tank 1, below the partition 7. Solenoid valves are installed on both the drain pipe 14 and the water inlet pipe 13. A liquid delivery pipe 10 is rotatably connected to the top of the mixing tube 6. One end of the liquid delivery pipe 10 is connected to the mixing tube 6, and the other end of the liquid delivery pipe 10 is connected to the coal chemical wastewater treatment catalyst delivery pipeline. Thus, the wastewater treatment catalyst can be delivered to the inside of the mixing tube 6 through the liquid delivery pipe 10 and discharged into the inside of the mixing tank 1 from the drain hole 11.

[0028] Please see Figure 3-5The longitudinal spoiler assembly 8 includes two transmission rods 81, which are rotatably connected to both sides of the inner wall of the mounting ring 16. The opposite ends of the two transmission rods 81 extend to both sides of the support platform 2. Both transmission rods 81 are rotatably connected to the support platform 2. The sides of the two transmission rods 81 that are separated from each other are bent and protruded. Movable sleeves 83 are rotatably fitted onto the bent ends of the two transmission rods 81. The movable sleeves 83 are rotatably connected to the transmission rods 81. Connecting rods 85 are fixedly connected to the bottom of both movable sleeves 83. Connecting seats 86 are hinged to the bottom ends of both connecting rods 85. A spoiler plate 82 is provided between the bottoms of the two connecting seats 86. Matching connecting seats 8 are provided on both sides of the top of the spoiler plate 82. The sliding groove allows the two connecting rods 85 to move up and down relative to each other through the two connecting seats 86, which in turn drive the two ends of the baffle plate 82 to tilt up and down alternately. This allows the load-bearing platform 2 to drive the longitudinal baffle assembly 8, the stirring pipe 6, and the stirring rod 12 to stir the wastewater inside the mixing tank 1, while driving the baffle plate 82 to tilt up and down and reciprocate. This creates a vortex effect on the wastewater containing the catalyst, effectively improving the mixing effect of the coal chemical wastewater. The rod surfaces of the two transmission rods 81 and the two sides of the bottom of the annular gear ring 9 are fixedly fitted with transmission wheels 84. The bottom of the annular gear ring 9 is uniformly fixedly connected with multiple teeth, and the annular gear ring 9 meshes with the two transmission wheels 84.

[0029] Detailed implementation: By opening the valve on the inlet pipe 13, sewage is transported into the interior of the mixing tank 1. The servo motor 3 is started, driving the drive wheel 4 to rotate. The drive wheel 4 drives the driven wheel 5 to rotate. The driven wheel 5 drives the support platform 2 to rotate. The support platform 2 drives the mixing tube 6, the mixing rod 12, and the longitudinal turbulence component 8 to stir the wastewater inside the mixing tank 1. At the same time, the wastewater treatment catalyst is transported into the interior of the mixing tube 6 through the liquid delivery pipe 10. The catalyst is also transported into the wastewater at different depths inside the mixing tank 1 through the drain hole 11 opened on the surface of the mixing tube 6, so as to achieve the effect of uniform catalyst delivery.

[0030] While the longitudinal turbulence assembly 8 rotates inside the mixing tank 1 via the mounting ring 16, the two transmission rods 81 drive the two transmission wheels 84 to revolve around the bottom of the annular gear ring 9. Because the transmission wheels 84 mesh with the annular gear ring 9, the two transmission rods 81 can rotate laterally. Since the two movable sleeves 83 are installed on the protrusions of the rods of the two transmission rods 81 and are rotatably connected to these protrusions, the rotation of the transmission rods 81 drives the movable sleeves 83 to move up and down. The two movable sleeves 83 drive the two connecting rods 85 to move up and down alternately, thereby driving the two connecting seats 86 to move up and down alternately. A baffle plate 82 is provided between the bottoms of the connecting seats 86. Both sides of the top of the baffle plate 82 are provided with sliding grooves that cooperate with the connecting seats 86 to slide. During the relative up and down movement of the two connecting rods 85, the two connecting seats 86 can drive the two ends of the baffle plate 82 to tilt up and down alternately. This allows the load-bearing platform 2 to drive the longitudinal baffle assembly 8, the stirring pipe 6 and the stirring rod 12 to stir the wastewater inside the mixing tank 1. At the same time, the baffle plate 82 is driven to tilt up and down and reciprocate. This can create a vortex turbulence effect on the wastewater containing the catalyst, effectively improving the mixing effect of the coal chemical wastewater. After processing, the valve on the drain pipe 14 can be opened to discharge the wastewater.

[0031] The servo motor 3 drives the stirring tube 6 and stirring rod 12 to stir the wastewater inside the stirring tank 1. At the same time, through the transmission connection between the annular gear ring 9 and the longitudinal turbulence component 8, the turbulence plate 82 inside the longitudinal turbulence component 8 can move up and down and tilt to turbulence the vortex generated during the stirring of the wastewater inside the stirring tank 1. No separate motor is required for turbulence, which reduces the use of motor units and effectively saves the operating cost of the coal chemical wastewater stirring device.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
