Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and in particular to a wastewater sedimentation tank diversion device. Background Technology

[0002] In industries such as construction and sand and gravel production, sand and gravel separators are widely used to clean and separate sand and gravel materials to recover sand and gravel resources. However, during the operation of sand and gravel separators, a large amount of wastewater is generated. This wastewater is usually discharged into a wastewater pond. Currently, existing wastewater ponds for sand and gravel separators have many problems, the most prominent being that excessive wastewater can cause serious pollution to the surrounding area. Regarding the aforementioned related technologies, the inventors believe that the traditional wastewater mixing tank inlet design is relatively simple, with only one inlet. Wastewater and circulating water mix and directly enter the mixing tank. This design leads to wastewater overflow during discharge due to the lack of effective diversion measures. This causes wastewater to not only flow into drainage ditches but also overflow onto the site, causing secondary pollution. Furthermore, it affects the cleanliness and hygiene of the work site, increases cleaning costs, and may pose potential hazards to the surrounding soil, water sources, and other environmental factors. Therefore, to solve the above problems, this application provides a wastewater sedimentation tank diversion device. Utility Model Content

[0003] To address the problems mentioned in the background art, this application provides a wastewater sedimentation tank diversion device.

[0004] The wastewater sedimentation tank diversion device provided in this application includes an inlet tank and a sedimentation tank body. A baffle wall is installed inside the inlet tank, which divides the inlet tank into a wastewater inlet and a circulating water inlet. A strip filter screen is installed inside the wastewater inlet.

[0005] Preferably, a flow guide plate is installed on the inner side wall of the sedimentation tank body near the inlet trough.

[0006] Preferably, the inner wall of the sedimentation tank body is connected to a drain pipe, and a valve is installed inside the drain pipe.

[0007] Preferably, a ring-shaped filter screen is installed on the top of the sedimentation tank body.

[0008] Preferably, both the wastewater inlet and the circulating water inlet are connected to the interior of the sedimentation tank body.

[0009] In summary, this application includes the following beneficial technical effects:

[0010] 1. By setting up two independent inlets and a baffle wall in the middle, sewage and circulating water can be reliably diverted into the mixing tank. Sewage and circulating water enter the mixing tank through their respective channels, avoiding mixing, which makes the subsequent treatment of sewage and circulating water more targeted and efficient, and improves the utilization efficiency of water resources.

[0011] 2. The effective separation of sewage and circulating water reduces the possibility of sewage overflow into drainage ditches and sites from the source, thereby solving the problem of secondary pollution of drainage ditches and sites by sewage generated by sand and gravel separators. This helps to keep the work site clean and hygienic, reduce cleaning costs, and reduce potential harm to the surrounding environment, resulting in significant environmental benefits.

[0018] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0019] Example 1:

[0020] Wastewater sedimentation tank diversion device, refer to Figure 1 , Figure 3 and Figure 5The system includes an inlet tank 1 and a sedimentation tank body 2. An internal baffle 3 separates the inlet tank 1 into a wastewater inlet 4 and a circulating water inlet 5. Wastewater and circulating water can enter the sedimentation tank body 2 through different channels, preventing them from mixing before entering the sedimentation tank. This lays the foundation for effective subsequent separation and treatment. For example, in a wastewater treatment system, wastewater from different sources and pre-treated circulating water can be separated by the baffle 3 and enter the sedimentation tank for treatment according to their respective appropriate methods. The wastewater inlet 4 is equipped with a strip-shaped flow channel. The filter screen 6, a strip-shaped filter screen installed inside the sewage inlet 4, is mainly used for preliminary filtration of the incoming sewage. Before flowing into the sedimentation tank, the sewage may contain some larger suspended impurities, such as twigs and plastic bags. The strip-shaped filter screen 6 can intercept these larger impurities, preventing them from entering the sedimentation tank body 2 and avoiding interference with the subsequent sedimentation process, such as clogging pipes or affecting the sedimentation effect. Its strip-shaped design allows for adjustment of the gap size as needed to accommodate the size characteristics of impurities in different sewage, ensuring effective filtration without excessively affecting the sewage flow rate.

[0021] Reference Figure 3 and Figure 4 A flow guide plate 7 is installed on the inner wall of the sedimentation tank body 2 near the inlet trough 1. When sewage and circulating water enter the sedimentation tank body 2 from the sewage inlet 4 and the circulating water inlet 5, the flow guide plate 7 begins to function. Its inclined angle design allows the incoming water to flow along the surface of the plate, changing the direction and speed of the water flow. On the one hand, this guiding effect can make the water flow enter the sedimentation tank more smoothly, avoiding turbulence caused by the water flow directly impacting the bottom or wall of the tank. Turbulence may cause the settled particles to be resuspended, affecting the sedimentation effect.

[0022] Reference Figure 3 and Figure 4 Inside the sedimentation tank body 2 and below the diversion inclined plate 7, a frustum-shaped diversion plate 8 is fixedly connected. The water flowing down from the diversion inclined plate 7 will impact the frustum-shaped diversion plate 8. The frustum-shaped structure has a unique diversion function, which can further disperse the water flow evenly in all directions. Due to the shape of the frustum, after the water flow comes into contact with the diversion plate 8, it will flow radially in all directions along the side of the frustum, making the water flow distribution on the cross-section of the sedimentation tank more uniform. This uniform distribution is very important for the sedimentation process, because it can ensure that suspended particles in the sewage have the opportunity to settle in a wider area, avoiding excessive concentration of particles in local areas, which would affect the sedimentation effect.

[0023] Reference Figure 3 and Figure 4The inner wall of the sedimentation tank body 2 is connected to a drain pipe 9, and a valve 10 is installed inside the drain pipe 9. The water after sedimentation treatment needs to be discharged from the sedimentation tank. The treated water can flow out through the drain pipe 9. The valve 10 is installed inside the drain pipe 9 to control the flow rate and time of the drain. The height of the drain pipe 9 should be a certain distance above the bottom of the tank to prevent the sludge at the bottom of the tank from being carried out by the water flow.

[0024] Reference Figure 1 and Figure 2 The top of the sedimentation tank body 2 is equipped with a ring-shaped filter screen 11, which can filter the falling rainwater and water. Some floating objects such as leaves and foam will be intercepted by the ring-shaped filter screen 11, preventing large impurities from entering the interior of the sedimentation tank body 2.

[0025] Reference Figure 2 and Figure 3 Both the sewage inlet 4 and the circulating water inlet 5 are connected to the interior of the sedimentation tank body 2. This connection allows the sewage and circulating water, after being diverted by the baffle wall 3, to smoothly enter the sedimentation tank body 2 for sedimentation treatment.

[0026] The implementation principle of the wastewater sedimentation tank diversion device in this embodiment is as follows: the baffle wall 3 divides the inlet tank 1 into a wastewater inlet 4 and a circulating water inlet 5. Wastewater and circulating water can enter the sedimentation tank body 2 through different channels, avoiding mixing before entering the sedimentation tank, thus laying the foundation for effective diversion treatment. The strip filter 6 installed inside the wastewater inlet 4 is mainly used for preliminary filtration of the incoming wastewater. Before flowing into the sedimentation tank, the wastewater may contain some larger suspended impurities, such as branches, plastic bags, etc. The strip filter 6 can intercept these larger impurities and prevent them from entering the sedimentation tank. The sedimentation tank body 2, designed to avoid interfering with subsequent sedimentation processes (such as clogging pipes or affecting sedimentation efficiency), features a strip-shaped design with adjustable gap sizes to accommodate the size characteristics of impurities in different wastewater samples. This ensures effective filtration without excessively affecting wastewater flow rate. A ring-shaped filter screen 11 is installed at the top of the sedimentation tank body 2 to filter rainwater and other floating debris such as leaves and foam, preventing large impurities from entering the sedimentation tank body 2. When wastewater and circulating water enter the sedimentation tank body 2 through the wastewater inlet 4 and circulating water inlet 5, the... The inclined plate 7 then comes into play. Its tilt angle design allows the incoming water to flow along the surface of the plate, changing the direction and speed of the water flow. On the one hand, this guiding effect allows the water to enter the sedimentation tank more smoothly, avoiding turbulence caused by the water directly impacting the bottom or walls of the tank. Turbulence may cause settled particles to resuspend, affecting the sedimentation effect. The water flowing down from the inclined plate 7 impacts the frustum-shaped diverter plate 8. The frustum-shaped structure has a unique diverting function, which can further disperse the water flow evenly in all directions. Due to the shape of the frustum, the water flow, upon contact with the diverter plate... After plate 8, the water will flow radially outwards along the side of the truncated cone, making the water flow more evenly distributed across the cross-section of the sedimentation tank. This even distribution is crucial for the sedimentation process because it ensures that suspended particles in the wastewater have a chance to settle over a wider area, avoiding excessive concentration of particles in local areas that would affect the sedimentation effect. The treated water needs to be discharged from the sedimentation tank. The treated water can flow out through the drain pipe 9. Valve 10 is installed inside the drain pipe 9 to control the flow rate and time of the drain. The height of the drain pipe 9 should be a certain distance above the bottom of the tank to prevent the sludge at the bottom of the tank from being carried out by the water flow.
