Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment devices, and more specifically, to a rapid sedimentation auxiliary structure. Background Technology

[0002] In the field of wastewater treatment, sedimentation is a crucial step in achieving solid-liquid separation and removing suspended impurities from wastewater. Its efficiency directly impacts the overall effectiveness and cost of wastewater treatment. Currently, most traditional wastewater treatment sedimentation technologies rely on gravity sedimentation. This involves setting up sedimentation tanks where wastewater flows slowly, allowing suspended particles to settle naturally to the bottom. While this method is simple and low-cost, it has several limitations in practical applications. Firstly, for suspended particles with small diameters and densities close to water, the natural settling rate is extremely slow, resulting in long sedimentation cycles and low treatment efficiency, making it difficult to meet the needs of large-scale wastewater treatment. Secondly, to ensure sufficient sedimentation time and effectiveness, sedimentation tanks often require a large area, which significantly restricts the construction and expansion of wastewater treatment plants in urban wastewater treatment scenarios where land resources are scarce.

[0003] To avoid the aforementioned problems and improve wastewater sedimentation treatment efficiency, wastewater is typically stored temporarily in tanks. Flocculants are then added to the wastewater to achieve sedimentation. After sedimentation, solid-liquid separation is performed. However, in this type of wastewater sedimentation using flocculants, most tanks are equipped with stirring components to ensure more thorough contact and reaction between the wastewater and flocculant. While this promotes complete mixing of the wastewater and flocculant, the stirring process also increases liquid flow and agitates the sediment, hindering its rapid settling to the bottom of the tank and affecting the rapid sedimentation effect. Therefore, we propose a rapid sedimentation auxiliary structure. Utility Model Content

[0004] The purpose of this invention is to provide a rapid precipitation auxiliary structure to address the deficiencies mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rapid sedimentation auxiliary structure includes a reaction tank. A wastewater pipe is fixedly installed on the top of the reaction tank. Multiple wastewater anti-clogging nozzles are fixedly installed at equal intervals on the bottom of the wastewater pipe extending into the reaction tank. A delivery pump is provided on one side of the reaction tank. A chemical solution pipe connected to a flocculant delivery pipeline is fixedly installed at the inlet end of the delivery pump. A delivery pipe is fixedly installed at the outlet end of the delivery pump. Multiple chemical solution nozzles are fixedly installed at equal intervals on the top of the delivery pipe extending into the reaction tank.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 Figures 1-3 This utility model provides a technical solution: a rapid sedimentation auxiliary structure, including a reaction tank 1. A sewage pipe 10 is fixedly installed on the top of the reaction tank 1. Multiple sewage anti-clogging nozzles 11 arranged at equal intervals are fixedly installed at the bottom of the sewage pipe 10 extending into the reaction tank 1. A transfer pump 12 is provided on one side of the reaction tank 1. A liquid pipe 121 connected to a flocculant delivery pipe is fixedly installed at the inlet end of the transfer pump 12. A delivery pipe 13 is fixedly installed at the outlet end of the transfer pump 12, extending into the reaction tank. Multiple equally spaced chemical spray nozzles 131 are fixedly installed on the top of the pipe body inside 1. The chemical spray nozzles 131 are located below the sewage anti-clogging nozzles 11, with the chemical spray nozzles 131 facing upwards and the sewage anti-clogging nozzles 11 facing downwards. This allows sewage to be sprayed downwards from the sewage anti-clogging nozzles 11 and flocculant to be sprayed upwards from the chemical spray nozzles 131. The two are fully mixed in the reaction tank 1 in an opposing manner, avoiding the sediment disturbance problem caused by traditional stirring. This achieves efficient mixing of sewage and flocculant, thereby accelerating sedimentation and improving treatment efficiency.

[0030] In this embodiment, the diameter of the water outlet hole on the sewage anti-clogging nozzle 11 is larger than the particle size of impurities in the sewage, thereby achieving the effect of preventing nozzle clogging.

[0031] like Figure 1 As shown, the liquid spray nozzle 131 and the sewage anti-clogging nozzle 11 are arranged in a staggered manner, which expands the mixing range of sewage and flocculant in the reaction tank 1; a top cover 14 is detachably installed on the top surface of the reaction tank 1. The detachable top cover 14 facilitates the inspection and cleaning of the inside of the reaction tank 1, ensuring the long-term stable operation of the equipment.

[0032] like Figure 1 and Figure 3 As shown, an exhaust pipe 2 is fixedly installed on the top cover 14. The exhaust pipe 2 has a U-shaped cross-section. Multiple baffles 20 are fixedly installed on the inner wall of the vertical section of the exhaust pipe 2 installed on the top cover 14, so that the gas in the reaction tank 1 can be discharged smoothly. At the same time, the baffles 20 prevent the water inside from splashing outward, avoid sewage leakage and pollution, and prevent the gas from carrying too much liquid when it is discharged, so as to ensure the safety and stability of the exhaust process.

[0033] like Figure 1As shown, multiple guide plates 15 are fixedly installed between the inner walls of the front and rear sides of the reaction tank 1. The cross-section of the guide plate 15 is inverted V-shaped, which changes the flow direction and path of sewage and flocculant in the reaction tank 1, prolongs the contact time between the two, promotes the continuous collision and reaction of the mixed liquid during the flow process, and makes the sewage and flocculant solution more fully contacted, further improving the sedimentation effect.

[0034] like Figure 1 As shown, multiple support legs 17 are fixedly installed at the bottom of the reaction vessel 1, and a fixed base 171 is fixedly installed at the bottom end of the support legs 17 to provide stable support for the reaction vessel 1, enhance the overall stability of the equipment, enable it to adapt to different installation environments, and ensure that the reaction vessel 1 will not be affected by external force shaking during operation.

[0035] like Figure 1 and Figure 2 As shown, a drain pipe 16 is fixedly installed at the bottom of the reaction tank 1, and a drain valve 161 is fixedly installed on the drain pipe 16 to facilitate the discharge of impurities and sludge settled at the bottom of the reaction tank 1, timely cleaning of sediment, prevention of impurity accumulation affecting subsequent sedimentation treatment, ensuring sufficient sedimentation space in the reaction tank 1, and maintaining sedimentation efficiency.

[0036] like Figure 1 and Figure 2 As shown, a solid-liquid separation device 3 is installed at the bottom of the reaction tank 1. The solid-liquid separation device 3 includes a drain pipe 30 fixedly installed at the bottom of the reaction tank 1 near the sewage pipe 16. A three-way pipe 31 is fixedly installed at the end of the drain pipe 30. A three-way valve 32 is fixedly installed on the three-way pipe 31. A filter screen 301 is fixedly installed on the inner wall of the end of the drain pipe 30 near the reaction tank 1. The filter screen 301 is used to block impurities. A discharge pipe 33 is fixedly installed on the other part of the three-way pipe 31. A backwash pipe 34 is fixedly installed on the remaining part of the three-way pipe 31. The backwash pipe 34 is connected to an external backwash pump to realize solid-liquid separation and flexible discharge of treated sewage. The backwash pipe 34 is connected to an external backwash pump. When the filter screen 301 is blocked, it can be flushed in time to avoid affecting the drainage efficiency due to filter screen blockage, ensure the smooth operation of the drainage system, and reduce manual maintenance costs.

[0037] It is worth noting that the bottom of the reaction vessel 1 is funnel-shaped, and the tilt angle of the filter screen 301 is the same as the tilt angle of the bottom wall of the reaction vessel 1, so that impurities can better converge along the filter screen 301 towards the drain pipe 16.

[0038] When using the rapid sedimentation auxiliary structure of this utility model, the wastewater to be treated is first sprayed downward into the reaction tank 1 through the external pump body and wastewater pipe 10 and the wastewater anti-clogging nozzle 11. At the same time, the delivery pump 12 draws external flocculant through the liquid pipe 121 and sprays it upward through the liquid pipe 13 and the liquid nozzle 131. The two are fully mixed in the reaction tank 1 by counter-current method to complete the initial reaction.

[0039] During the flow of the mixed liquid in the reaction tank 1, it will pass through the inverted V-shaped guide plate 15. The guide plate 15 changes the flow direction and path of the mixed liquid, prolongs the contact time between the sewage and the flocculant, and further promotes the full reaction. The mixed liquid completes the sedimentation operation at the bottom of the reaction tank 1, promoting rapid sedimentation.

[0040] The gas generated during the reaction is discharged through the U-shaped exhaust pipe 2 on the top cover 14. The end of the U-shaped exhaust pipe 2 is connected to the external waste gas treatment equipment. The water baffle 20 inside the pipe prevents water from splashing outward.

[0041] After sedimentation is complete, open the three-way valve 32 to connect the drain pipe 30 and the discharge pipe 33. At this time, the clear liquid filtered by the filter screen 301 can be discharged through the discharge pipe 33. After the clear liquid is discharged, open the drain valve 161 on the drain pipe 16 to discharge the impurities and sludge settled at the bottom of the reaction tank 1. When the filter screen 301 is clogged, connect it to the external backwash pump through the backwash pipe 34 to backwash the filter screen 301 to ensure the normal operation of the drainage system.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
