Description

Technical Field

[0001] This utility model relates to the field of phosphorus removal technology, and more specifically, to a phosphorus removal device for wastewater. Background Technology

[0002] In existing technologies, the wastewater phosphorus removal equipment lacks effective filtration and discharge methods after phosphorus removal, and the flow rate and velocity of the pipeline are inconvenient to adjust, resulting in certain limitations in treatment effect and operation and maintenance.

[0003] Firstly, while existing phosphorus removal equipment can effectively remove phosphorus from water after agitation, it often lacks a high-efficiency filtration system at the wastewater discharge stage. This results in wastewater containing tiny phosphorus particles or other pollutants not being adequately purified. The lack of filtration not only prevents wastewater from meeting discharge standards but can also lead to water pollution and impact the surrounding ecosystem. Furthermore, an improperly designed filtration system can cause problems such as filter blockage and damage, leading to unstable equipment operation and further increasing maintenance costs.

[0004] Secondly, the flow rate and velocity regulation of existing equipment usually rely on simple valves or mechanical devices. The regulation process is cumbersome and imprecise. In the wastewater treatment process, changes in flow rate and velocity directly affect the uniformity of water flow and the treatment effect. Especially during the peak period of wastewater treatment, when the flow rate fluctuates greatly, the existing equipment regulation methods often cannot respond quickly, resulting in reduced treatment efficiency, or even over- or under-treatment, affecting the final wastewater discharge quality.

[0022] Please see Figures 1-5 A phosphorus removal device for wastewater includes a mixing tank assembly 1, a vibration filtration mechanism, a communication adjustment mechanism, and an adjustment auxiliary mechanism. The vibration filtration mechanism includes a vibration box 2 and a frame 3. Vibration springs 4 are installed around the top of the frame 3, and the top of the vibration springs 4 is connected to the bottom of the vibration box 2. A top frame 5 is installed on the top of the frame 3, and a hydraulic cylinder 6 is installed on the top frame 5. A filter screen assembly 7 is installed at the output end of the hydraulic cylinder 6. The filter screen assembly 7 is directionally sliding within the vibration box 2. The communication adjustment mechanism includes... The regulating pipe 8 and the corrugated plate 9 are provided. The corrugated plate 9 is installed on the inner wall of the regulating pipe 8 and is arranged in multiple rings. The anti-tension spring rod 10 is slidably installed on the side wall of the regulating pipe 8 and is arranged in multiple groups. An inner support frame 11 is connected between adjacent anti-tension spring rods 10. The upper limit rotating sleeve 101 is located on the outer wall of the regulating pipe 8. The inner wall of the rotating sleeve 101 is provided with an arc groove 12. The inner wall of the rotating sleeve 101 and the arc groove 12 can press against the anti-tension spring rod 10, so that the inner support frame 11 is compressed inward.

[0023] In this embodiment, after the vibration motor 22 is started, it drives the vibration box 2 to vibrate. The vibration is transmitted to the frame 3 through the surrounding vibration springs 4. The hydraulic cylinder 6 controls the filter screen assembly 7 to slide directionally within the vibration box 2. Combined with the vibration, dynamic filtration and separation of sewage is achieved, effectively removing impurities such as phosphorus particles. The vibration enhances the filtration efficiency and prevents the filter screen from clogging. When the sewage flows through the regulating pipe 8, multiple sets of annular corrugated plates 9 on the inner wall play a role in turbulence and increasing the contact area. When the rotating sleeve 101 rotates, the arc groove 12 on the inner wall presses against the anti-tension spring rod 10, causing the inner support frame 11 between adjacent anti-tension spring rods 10 to compress inward. The inner diameter and flow rate of the regulating pipe 8 are adjusted. By controlling the rotation angle of the rotating sleeve 101, the flow cross section of the pipe can be precisely adjusted.

[0024] The adjustment auxiliary mechanism includes a ring fixing plate 13 and a top-supporting ring 14. The top-supporting ring 14 is symmetrically installed at the top and bottom ends of the rotating sleeve 101. Two sets of ring fixing plates 13 are fixedly installed on the outer wall of the adjustment tube 8. The ring fixing plates 13 are symmetrically installed at the top and bottom of the rotating sleeve 101. Positioning springs 15 are installed on the ring fixing plates 13, and multiple sets of positioning springs 15 are provided. Positioning grooves 16 are opened on the top-supporting ring 14. The positioning springs 15 extend into the positioning grooves 16 step by step to make the rotating sleeve 101 rotate stably.

[0025] In this embodiment, multiple sets of positioning springs 15 on the ring plate 13 extend into the positioning grooves 16 of the top ring 14 in stages, providing a stable graded positioning function for the rotating sleeve 101. The top ring 14 is symmetrically installed on the top and bottom of the rotating sleeve 101 to ensure that the rotating sleeve 101 rotates stably during the adjustment process, prevents excessive rotation or accidental loosening, and provides precise adjustment control.

[0026] Please see Figures 1-5 As a supplementary embodiment of a wastewater phosphorus removal device with a vibration filtration mechanism, a connecting adjustment mechanism, and an adjustment auxiliary mechanism: A base plate 17 is installed at the bottom end of the frame 3, and the bottom end of the mixing tank assembly 1 is installed at the top end of the base plate 17. A bottom pipe 18 is installed at the bottom end of the mixing tank assembly 1, and a pump body 19 is installed at one end of the bottom pipe 18. The pump body 19 is installed at the top end of the base plate 17, and a charging pipe 20 is installed at one end of the pump body 19. One end of the charging pipe 20 is connected to the bottom end of the vibration box 2. The charging pipe 20 is segmented, and both ends of the adjustment pipe 8 are connected to the charging pipe 20. Connecting plates 21 are installed at both ends of the adjustment pipe 8, and the adjustment pipe 8 and the charging pipe 20 are fixedly connected by the connecting plates 21. A vibration motor 22 is installed on the side of the vibration box 2.

[0027] More specifically, the mixing tank assembly 1 collects the wastewater to be treated, and the bottom pipe 18 and pump body 19 form the conveying power. The wastewater is conveyed through the filling pipe 20, and the corrugated plate 9 in the regulating pipe 8 enhances the mixing effect. The flow rate is controlled by the regulating mechanism. The wastewater enters the vibrating box 2, and under the action of the vibrating motor 22, the filter screen assembly 7 performs dynamic filtration to remove pollutants such as phosphorus. The regulating auxiliary mechanism ensures that each regulating parameter is stable and controllable. The positioning spring 15 and positioning groove 16 provide precise positioning. The treated wastewater can be recycled back or discharged to form a continuous phosphorus removal process.

[0028] In summary, when the overall equipment is in use or running: when the vibration filtration mechanism is required to run, the vibration motor 22 starts and drives the vibration box 2 to vibrate. The vibration is transmitted to the frame 3 through the surrounding vibration springs 4. The hydraulic cylinder 6 controls the filter screen assembly 7 to slide in the direction within the vibration box 2. Combined with the vibration, dynamic filtration and separation of sewage is achieved, effectively removing impurities such as phosphorus particles. The vibration enhances the filtration efficiency and prevents the filter screen from clogging.

[0029] When the regulating mechanism needs to be connected, as sewage flows through the regulating pipe 8, multiple sets of annular corrugated plates 9 on the inner wall play a role in turbulence and increasing the contact area. When the rotating sleeve 101 rotates, the arc groove 12 on the inner wall presses against the anti-tension spring rod 10, causing the inner support frame 11 between adjacent anti-tension spring rods 10 to compress inward. The inner diameter and flow velocity of the regulating pipe 8 are adjusted by controlling the rotation angle of the rotating sleeve 101, thereby achieving precise adjustment of the flow cross section of the pipe.

[0030] When the auxiliary mechanism needs to be adjusted, multiple sets of positioning springs 15 on the ring plate 13 extend into the positioning grooves 16 of the top ring 14 in stages, providing a stable graded positioning function for the rotating sleeve 101. The top ring 14 is symmetrically installed on the top and bottom of the rotating sleeve 101 to ensure that the rotating sleeve 101 rotates stably during the adjustment process, prevents excessive rotation or accidental loosening, and provides precise adjustment control.

[0031] The mixing tank assembly 1 collects the wastewater to be treated and forms a conveying power through the bottom pipe 18 and the pump body 19. The wastewater is conveyed through the filling pipe 20. The corrugated plate 9 in the regulating pipe 8 enhances the mixing effect. The flow rate is controlled by the regulating mechanism. The wastewater enters the vibrating box 2. Under the action of the vibrating motor 22, the filter assembly 7 performs dynamic filtration to remove pollutants such as phosphorus. The regulating auxiliary mechanism ensures that each regulating parameter is stable and controllable. The positioning spring 15 and the positioning groove 16 provide precise positioning. The treated wastewater can be recycled back or discharged to form a continuous phosphorus removal process.
