Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a high-efficiency and environmentally friendly wastewater treatment device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as energy, petrochemicals, and environmental protection. During the wastewater treatment process, workers add an appropriate amount of flocculant to the wastewater to cause suspended solids, colloidal particles, and other small pollutants to aggregate into larger flocs, which facilitates subsequent sedimentation, filtration, and other treatments, thereby improving the overall wastewater treatment efficiency.

[0003] In existing wastewater treatment equipment, the flocculant inlet is usually located in a fixed position on one side of the wastewater treatment tank. This makes it difficult for the flocculant to spread quickly and evenly in the wastewater after entering the tank. It takes a long time for the flocculant to fully contact the wastewater in all parts of the tank, which has a certain impact on the wastewater treatment efficiency and is not conducive to the normal operation of wastewater treatment.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] Please see Figure 1-9As shown, a high-efficiency and environmentally friendly wastewater treatment device includes a treatment tank 1, a tank top cover 2 adapted to the tank 1, a support platform 3 fixedly connected to the center of the top surface of the tank top cover 2, a hollow pipe 4 coaxially rotatably connected inside the support platform 3, and an outer sleeve 5 coaxially rotatably connected to the outside of the hollow pipe 4; a drive assembly 6 is set inside the support platform 3. By setting the drive assembly 6, the flow direction of the wastewater inside the treatment tank 1 can be disturbed during the stirring process, thereby creating turbulence inside the wastewater, which allows the flocculant to be evenly distributed and reach the target area. The various locations inside the treatment tank 1 facilitate sufficient contact between wastewater and flocculant. A wastewater inlet pipe 15 is provided on the top side of the treatment tank 1 to facilitate the input of external wastewater into the treatment tank 1. A dosing component 10 is provided on the outside of the outer sleeve 5 to ensure uniform and sufficient contact between the flocculant and the wastewater inside the treatment tank 1, thereby improving the wastewater treatment efficiency. By setting the dosing component 10, the wastewater inside the treatment tank 1 can be made to fully contact with the flocculant, which helps to accelerate the agglomeration of small pollutants such as suspended solids and colloidal particles in the wastewater, thereby improving the overall wastewater treatment efficiency.

[0030] The dosing assembly 10 includes at least three liquid output pipes 101 disposed around the outer sleeve 5. These multiple liquid output pipes 101 are distributed circumferentially along the inner wall of the treatment tank 1. A limiting seat 105 is fixedly connected to the outer side of the outer sleeve 5, and a limiting sleeve 104 is rotatably connected to the outer side of the limiting seat 105. The top end of the liquid output pipe 101 is connected to the limiting sleeve 104, and the bottom end of the liquid output pipe 101 is connected to the hollow tube 4. Multiple U-shaped sections 102 are symmetrically arranged on the outer side of the liquid output pipe 101. Each U-shaped section 102 has intermittently spaced liquid spray nozzles 103 inside. Figure 3 , Figure 7 and Figure 8 As shown, the hollow tube 4 can drive multiple liquid output pipes 101 located around the outer tube 5 to rotate together. This allows the liquid output pipes 101 to spray flocculant through the liquid nozzle 103 while continuously changing the spray position of the flocculant inside the treatment tank 1. This ensures that the flocculant comes into uniform and sufficient contact with the sewage inside the treatment tank 1, which is beneficial for accelerating the agglomeration of small pollutants such as suspended solids and colloidal particles in the sewage and improving the overall sewage treatment efficiency.

[0031] Multiple second stirring blades 13 are symmetrically installed on the outer side of the outer sleeve 5. An L-shaped plate 11 is provided on the side of the liquid output pipe 101 away from the outer sleeve 5. Multiple first stirring blades 12 are symmetrically installed on the side of the L-shaped plate 11 facing the second stirring blades 13. The other side of the L-shaped plate 11 is connected to the inner wall of the treatment tank 1. Figure 3 , Figure 4 and Figure 9As shown, multiple U-shaped sections 102 are symmetrically arranged on the liquid output pipe 101, making the liquid output pipe 101 form an S-shaped shape that is more suitable for the arrangement of the first stirring blade 12 and the second stirring blade 13. When the flocculant is added through the dosing assembly 10, the first stirring blade 12 and the second stirring blade 13 will pass through the outside and inside of the U-shaped section 102, respectively. During this process, the flocculant sprayed from the liquid nozzles 103 on the outside and inside of the U-shaped section 102 will be quickly mixed into the sewage under the action of the first stirring blade 12 and the second stirring blade 13, thus promoting full contact between the sewage and flocculant inside the treatment tank 1.

[0032] The drive assembly 6 includes a first driven bevel gear 63 fixed to the outer side of the top end of the hollow tube 4, a second driven bevel gear 64 fixedly connected to the outer side of the top end of the outer sleeve 5, and a drive motor 61 fixedly installed on the top of one side of the tank top cover 2. The output end of the drive motor 61 extends through the interior of the support platform 3 and is fixedly connected to a driving bevel gear 62. The driving bevel gear 62 meshes with the first driven bevel gear 63 and the second driven bevel gear 64 respectively. Figure 3 , Figure 5 and Figure 6 As shown, in actual use, the drive motor 61 can drive the active bevel gear 62 to rotate. Then, the active bevel gear 62 drives the outer sleeve 5 to rotate in the opposite direction to the hollow tube 4 through the first driven bevel gear 63 and the second driven bevel gear 64. This can drive the second stirring paddle 13 on the outside of the outer sleeve 5 to rotate in the opposite direction to the liquid output pipe 101 on the outside of the hollow tube 4, thereby disrupting the flow direction of the sewage inside the treatment tank 1 and causing turbulence inside the sewage. This allows the flocculant to be evenly distributed and reach all positions inside the treatment tank 1.

[0033] The tank top cover 2 is equipped with a reinforcing baffle 7 inside to keep the outer sleeve 5 stable during rotation, such as Figure 3 , Figure 5 As shown, by setting the reinforcing baffle 7, the overall support strength of the tank top cover 2 to the outer tube 5 is enhanced, so that the outer tube 5 and its internal hollow tube 4 can effectively resist the influence of centrifugal force when rotating, which is conducive to improving the working stability of the drive assembly 6 and the dosing assembly 10.

[0034] Both the top edge of the processing tank 1 and the bottom edge of the tank cover 2 are provided with mating parts 14, which are connected by bolts. Figure 1 , Figure 2 As shown, by setting the docking part 14, it is easy to assemble and disassemble the processing tank 1 and the tank top cover 2, thereby facilitating the maintenance and repair of the internal components of the processing tank 1 and the tank top cover 2 by the staff.

[0035] A first annular seat 17 is fixedly connected to the outer side of the processing tank 1. A second annular seat 18 is provided below the first annular seat 17. Multiple support columns 19 are symmetrically installed on the top of the second annular seat 18. The top ends of the support columns 19 are connected to the first annular seat 17. Figure 1 , Figure 2 As shown, the support formed by the first annular seat 17 and multiple pillars 19 can support the entire processing tank 1, thereby allowing the entire processing tank 1 to sit stably on the ground.

[0036] The bottom of the treatment tank 1 is equipped with a sewage outlet pipe 16, and a solenoid valve is installed inside the sewage outlet pipe 16, such as... Figure 3 As shown, after the wastewater and flocculant are fully mixed by the drive component 6 and the dosing component 10, the wastewater can be transported to the sedimentation tank through the wastewater outlet pipe 16 in conjunction with the external wastewater pipe, so as to facilitate the subsequent sedimentation of pollutants in the wastewater.

[0037] The top end of the hollow tube 4 extends to the outside of the support platform 3 and is equipped with a rotary joint 8. The top end of the rotary joint 8 is equipped with a liquid inlet pipe 9. The rotary joint 8 is connected to both the hollow tube 4 and the liquid inlet pipe 9. Figure 2 , Figure 7 and Figure 8 As shown, by setting the rotary joint 8, the flocculant can be stably fed into the interior of the hollow tube 4 through the liquid inlet pipe 9 without hindering the rotation of the hollow tube 4.

[0038] Working principle: First, the staff uses the sewage inlet pipe 15 to input the external sewage to be purified into the treatment tank 1. Then, the dosing component 10 drives multiple liquid output pipes 101 located on the outer casing 5 to spray flocculant inside the treatment tank 1. This allows the flocculant to come into uniform and sufficient contact with the sewage inside the treatment tank 1, which is beneficial to accelerate the agglomeration of small pollutants such as suspended solids and colloidal particles in the sewage and improve the overall sewage treatment efficiency. At the same time, the drive component 6 drives the second stirring blade 13 on the outer casing 5 to rotate in the opposite direction to the liquid output pipes 101 on the outer casing 4. Combined with the first stirring blade 12, this disturbs the flow direction of the sewage inside the treatment tank 1, causing turbulence inside the sewage. This allows the flocculant to be evenly distributed and reach all positions inside the treatment tank 1, promoting full contact between the sewage and the flocculant inside the treatment tank 1.
