Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment sedimentation tank technology, and in particular to a high-efficiency sedimentation tank for wastewater treatment. Background Technology

[0002] Commonly used methods for treating heavy metal wastewater can be divided into three main categories: physical methods, chemical methods, and biological methods. Among them, flocculation involves adding flocculants to the wastewater to form flocs, which eventually settle out due to gravity.

[0003] In existing wastewater treatment methods using flocculation, the flocculants mixed with the flocculant accumulate at the bottom of the tank due to gravity during the flow of the wastewater. The impact force generated during subsequent wastewater transport can directly impact the sludge or wastewater in the sedimentation tank, resulting in poor sedimentation performance. Utility Model Content

[0004] The main purpose of this invention is to provide a high-efficiency sedimentation tank for wastewater treatment.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A high-efficiency sedimentation tank for wastewater treatment includes a sedimentation tank, an inlet pipe installed above one side of the sedimentation tank, a drainage assembly installed on the side of the sedimentation tank away from the inlet pipe, and a water-blocking assembly installed inside the sedimentation tank near the inlet pipe. The water-blocking assembly includes a baffle fixed inside the sedimentation tank, and multiple sets of guide plates are symmetrically installed on the baffle and inside the sedimentation tank. A float is provided below the guide plate at the bottom end, and connecting rods are symmetrically installed on one side of the float.

[0007] Preferably, the drainage assembly includes a water tank and a drain pipe, and the drain pipe is installed at the bottom of the water tank.

[0008] Preferably, the baffle is provided with a slot, and the connecting rod passes through the baffle through the slot.

[0009] Preferably, guide grooves are provided on both sides of the empty groove, and a slider is slidably connected in the guide groove, and the slider is fixedly connected to the connecting rod.

[0010] Preferably, the guide plate is inclined, and multiple sets of through holes are evenly formed on the guide plate.

[0011] Preferably, the bottom of the sedimentation tank near the drainage component has an inclined structure, and multiple sets of shielding components are installed at the inclined section of the sedimentation tank.

[0012] Preferably, the shielding assembly includes a mounting frame fixed inside the sedimentation tank, and a filter screen is fixed on the mounting frame.

[0013] Preferably, an overflow trough is provided on the sedimentation tank near the drainage component, and the water tank and the sedimentation tank are connected through the overflow trough.

[0014] The beneficial effects of this technology are:

[0015] By installing a water-blocking component, when the wastewater containing the mixed flocculant enters the sedimentation tank, it comes into contact with the baffles inside the water-blocking component, changing its flow from horizontal to vertical. As the wastewater falls vertically, it comes into contact with the staggered guide plates. The guide plates effectively block the formed flocs in the wastewater and increase their flocculation volume by allowing the flocs to come into contact with each other. The wastewater falls vertically, and the buoyancy of the water allows the floats to move along the baffles via connecting rods. The floats can block some of the falling flocs, thus preventing a large amount of flocs from flowing with the wastewater, thereby improving the sedimentation efficiency of the sedimentation tank.

[0022] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0023] like Figures 1-4As shown in the figure, this embodiment provides a high-efficiency sedimentation tank for wastewater treatment, including a sedimentation tank 1. An inlet pipe 2 is installed above one side of the sedimentation tank 1, facilitating the entry of wastewater with added mixed flocculant into the sedimentation tank 1 through the inlet pipe 2. A drainage assembly 3 is installed on the side of the sedimentation tank 1 away from the inlet pipe 2. A water-blocking assembly 4 is installed inside the sedimentation tank 1 near the inlet pipe 2. The water-blocking assembly 4 includes a baffle 401 fixed inside the sedimentation tank 1. The baffle 401 can change the wastewater flow from horizontal to vertical. The baffle 401 and other components are symmetrically installed inside the sedimentation tank 1. Multiple sets of guide plates 402 are used. When wastewater falls vertically, it will come into contact with the staggered guide plates 402. The guide plates 402 can effectively block the flocs formed in the wastewater and make the flocs come into contact with each other to increase their flocculation volume. A float 403 is set below the bottom guide plate 402. A connecting rod 404 is symmetrically installed on one side of the float 403. The buoyancy of the water can make the float 403 move along the baffle 401 through the connecting rod 404. The float 403 can block some of the falling flocs, thereby preventing a large amount of flocs from flowing with the wastewater.

[0024] like Figures 1-2 As shown, the drainage component 3 includes a water tank 301 and a drain pipe 302, and the drain pipe 302 is installed at the bottom of the water tank 301 to facilitate the upper layer of liquid formed after sedimentation to enter the water tank 301 and be discharged through the drain pipe 302.

[0025] like Figure 1 and Figure 3 As shown, a slot 5 is provided on the baffle 401, and the connecting rod 404 passes through the baffle 401 through the slot 5, so that the connecting rod 404 can move along the baffle 401 through the slot 5.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, guide grooves 6 are provided on both sides of the empty groove 5, and a slider 7 is slidably connected in the guide groove 6. The slider 7 is fixedly connected to the connecting rod 404, so that the slider 7 can move along the guide groove 6 to guide it during the movement of the connecting rod 404.

[0027] like Figures 2-3 As shown, the guide plate 402 is inclined, and multiple sets of through holes 8 are evenly opened on the guide plate 402 to facilitate the rapid passage of wastewater through the through holes 8 through the guide plate 402.

[0028] like Figures 1-2 As shown, the bottom of the sedimentation tank 1 near the drainage component 3 has an inclined structure, and multiple sets of shielding components 9 are installed at the inclined section of the sedimentation tank 1, which can block the flocs inside the wastewater during the flow of wastewater.

[0029] like Figures 1-2As shown, the shielding component 9 includes a mounting frame 901 fixed inside the sedimentation tank 1, and a filter screen 902 is fixed on the mounting frame 901, so that the filter screen 902 can be fixed inside the sedimentation tank 1 through the mounting frame 901 and the filter screen 902 can shield the flocculent.

[0030] like Figures 1-2 As shown, an overflow trough 10 is provided on the sedimentation tank 1 near the drainage component 3. The water tank 301 is connected to the sedimentation tank 1 through the overflow trough 10, which allows the upper liquid to enter the water tank 301 through the overflow trough 10.

[0031] The working principle of this device is as follows: In practical use, wastewater with added mixed flocculant enters the sedimentation tank 1 through the inlet pipe 2. Upon entering the sedimentation tank 1, the wastewater comes into contact with the baffles 401 within the water-blocking assembly 4, changing its flow from horizontal to vertical. As the wastewater falls vertically, it comes into contact with the staggered guide plates 402. The guide plates 402 effectively block the formed flocs in the wastewater and increase their flocculation volume through mutual contact. The wastewater then falls vertically and passes through the water... Buoyancy enables the float 403 to move along the baffle 401 via the connecting rod 404. The float 403 can block some of the falling flocs, thereby preventing a large amount of flocs from flowing with the wastewater and improving the sedimentation efficiency of the sedimentation tank 1. During the movement of the connecting rod 404, the slider 7 can move along the guide groove 6 to guide it. During the flow of wastewater, the filter screen 902 is fixed in the sedimentation tank 1 by the mounting bracket 901. The filter screen 902 blocks the flocs, and the upper liquid enters the water tank 301 through the overflow groove 10 and is discharged through the drain pipe 302.

[0032] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
