Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to a wastewater purification device for urban sewage pipe networks. Background Technology

[0002] With the acceleration of urbanization in my country, the amount of urban sewage discharge is increasing day by day, which places higher demands on the treatment capacity of sewage pipe networks. Traditional urban sewage pipe networks mainly undertake the function of sewage collection and transportation, lacking the capacity for sewage purification and treatment, resulting in a large amount of untreated sewage being directly discharged into water bodies, causing serious environmental pollution.

[0003] To address this issue, in recent years, some researchers have proposed integrating purification functions into sewage pipe networks and developed various sewage pipe network purification devices. These devices perform preliminary purification of sewage by setting up units such as filtration, sedimentation, and biological treatment within the pipe network, thereby reducing the pressure on end-of-pipe sewage treatment plants.

[0004] However, in practical applications, urban sewage may contain a large amount of suspended solids and impurities that are prone to clogging. These substances can easily accumulate in the filtration units, channels, or treatment units of the purification device, causing blockages in the water flow channels. This not only reduces the treatment efficiency of the device but also causes problems such as pipeline overflow, indicating significant shortcomings. Utility Model Content

[0005] To address the problem of suspended solids and impurities easily clogging purification devices, this application provides a sewage purification device for urban sewage pipe networks.

[0006] The wastewater purification device for urban sewage pipe networks provided in this application adopts the following technical solution:

[0007] A sewage purification device for an urban sewage pipe network includes a filter tank with an open top, an inlet pipe and an outlet pipe connected to the filter tank, the inlet pipe extending into the filter tank, a filter permeable bag placed inside the filter tank, the filter permeable bag being hollow inside and having a cleaning port, the cleaning port being tightened to the inlet pipe by a tension band.

[0008] By adopting the above technical solution, sewage enters the filter permeable bag from the inlet pipe. Since the filter permeable bag itself has a small pore size, sewage can pass through the filter permeable bag into the filter tank, while suspended solids and impurities can only be intercepted in the filter permeable bag, thereby reducing the possibility of suspended solids and impurities clogging the water purification device.

[0009] Optionally, a limiting ring is arranged on the outer wall of the water inlet pipe, and the tensioning band is located on the side of the limiting ring facing away from the inner cavity of the filter water-permeable bag.

[0010] By adopting the above technical solution, the limiting ring plays a limiting role in the tensioning belt, reducing the possibility that the filter water-permeable bag will fall off the water inlet pipe due to the impact of sewage.

[0011] Optionally, a hanging rack is provided on the filter tank, and a hanging strap is arranged on the filter water-permeable bag for hanging on the hanging rack. When the hanging strap is hung on the hanging rack, the filter water-permeable bag is suspended in the air.

[0012] By adopting the above technical solution, when the filter bag is in use, the worker hangs the strap on the rack, so that the filter bag is kept in a suspended state, ensuring the efficiency of sewage passing through the filter bag.

[0013] Optionally, the bracket is slidably arranged on the filter tank, and a hook is arranged on one side of the bracket. A hanging rope is attached to the hook, and the other end of the hanging rope is attached to a hanging strap.

[0014] By adopting the above technical solution, when the filter bag is full of suspended solids and impurities, the worker pulls the filter bag upward with a rope. After the sewage in the filter bag is drained, the hanging frame is pushed to bring the filter bag close to the edge of the filter tank, so that it can be easily removed and cleaned.

[0015] Optionally, the filter permeable bladder has a cable tie for securing the cleaning port.

[0016] By adopting the above technical solution, the cable ties can be used to seal the cleaning port, reducing the possibility of leakage of suspended solids and impurities during the draining process.

[0017] Optionally, a rotating rod is rotatably mounted on the water inlet pipe, and a valve plate for sealing the water inlet pipe is arranged on the rotating rod.

[0018] By adopting the above technical solution, workers manually rotate the lever to turn the valve plate to block the inlet pipe, reducing the possibility of suspended solids and impurities entering the filter tank during the cleaning of the filter permeable bag.

[0019] Optionally, the valve plate is provided with a sealing strip for tightly adhering to the inner wall of the water inlet pipe.

[0020] By adopting the above technical solution, the sealing strip improves the sealing performance between the valve plate and the inlet pipe, reducing the possibility of sewage leakage.

[0021] Optionally, the rotating rod has a mounting block arranged on its body outside the water inlet pipe, and the mounting block is threaded with a fastening bolt for abutting against the outer wall of the water inlet pipe.

[0022] By adopting the above technical solution, workers tighten the fastening bolts to make them press against the outer wall of the water inlet pipe, thereby locking the position of the valve plate and reducing the possibility of the valve plate rotating due to sewage impact.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Wastewater enters the filter permeable bag from the inlet pipe. Because the filter permeable bag itself has a small pore size, the wastewater can pass through the filter permeable bag into the filter tank, while suspended solids and impurities can only be intercepted in the filter permeable bag, thereby reducing the possibility of suspended solids and impurities clogging the water purification device.

[0025] 2. When the filter bag is full of suspended solids and impurities, the worker pulls the filter bag upward with a rope. After the sewage in the filter bag has drained, the worker pushes the frame to bring the filter bag close to the edge of the filter tank, so that it can be easily removed and cleaned.

[0029] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0030] This application discloses a sewage purification device for urban sewage pipe networks.

[0031] Reference Figure 1 and Figure 2 The sewage purification device of the urban sewage pipe network includes a filter pool 1 with an open top. The filter pool 1 is rectangular and has an inlet pipe 2 connected to one end and an outlet pipe 3 connected to the other end. The inlet pipe 2 extends into the filter pool 1 and has a circumferentially integrally formed limiting ring 6 on its outer wall.

[0032] Reference Figure 1 and Figure 2 The filter tank 1 contains a hollow filter water-permeable bag 4. The filter water-permeable bag 4 is bulb-shaped and has a cleaning port 41. The cleaning port 41 is tightened to the water inlet pipe 2 by a tension band 5. The tension band 5 is located on the side of the limiting ring 6 facing away from the inner cavity of the filter water-permeable bag 4.

[0033] Wastewater enters the filter bag 4 from the inlet pipe 2. Because the filter bag 4 has a small pore size, it can only allow wastewater to pass through, while suspended solids and impurities cannot pass through. Therefore, it can filter and intercept suspended solids and impurities.

[0034] Reference Figure 1 and Figure 2 A hanging bracket 7 is slidably arranged on the filter tank 1. The hanging bracket 7 is U-shaped and inverted on the filter tank 1. A hook 9 is welded to one side of the hanging bracket 7, and a hanging rope 10 is attached to the hook 9. A hanging strap 8 is attached to the filter water-permeable bag 4. The top of the hanging bracket 7 has an opening for the strap (not shown in the figure), and the hanging rope 10 passes through the opening for the strap and is attached to the hanging strap 8.

[0035] Reference Figure 1 and Figure 2 When the filter bag 4 is in use, the hanging rope 10 is tied to the hook 9, and the rope pulls the hanging strap 8, so that the filter bag 4 is suspended in the filter tank 1, thereby improving the efficiency of sewage passing through the filter bag 4.

[0036] Reference Figure 1 and Figure 2 The filter water-permeable bag 4 has a cable tie 11 for binding the cleaning port 41. When the filter water-permeable bag 4 is full of suspended solids and impurities, the worker manually removes the tension belt 5 from the water inlet pipe 2 and then binds the cleaning port 41 with the cable tie 11.

[0037] Subsequently, the filter bag 4 is lifted upward by the hanging rope 10, thereby removing the filter bag 4 from the sewage. After it is drained, the hanging frame 7 is pushed to move the filter bag 4 closer to the edge of the filter tank 1, which makes it easier to remove the filter bag 4 and clean it.

[0038] Reference Figure 1 and Figure 2 A rotating rod 12 is rotatably installed on the water inlet pipe 2. A valve plate 13 for sealing the water inlet pipe 2 is welded on the rotating rod 12. A sealing strip 14 for tightly adhering to the inner wall of the water inlet pipe 2 is bonded to the valve plate 13.

[0039] The worker manually rotates lever 12, causing valve plate 13 to rotate to block inlet pipe 2, reducing the possibility of suspended solids and impurities entering filter tank 1 during the cleaning of filter permeable bag 4.

[0040] Reference Figure 1 and Figure 2 The rotating rod 12 is fixedly fitted with a mounting block 15 on the rod body outside the water inlet pipe 2. The mounting block 15 is threaded with a fastening bolt 16 for pressing against the outer wall of the water inlet pipe 2.

[0041] The worker tightens the fastening bolt 16 to press it against the outer wall of the water inlet pipe 2, thereby locking the position of the valve plate 13 and reducing the possibility of the valve plate 13 rotating due to the impact of sewage.

[0042] The implementation principle of a sewage purification device for an urban sewage pipe network according to an embodiment of this application is as follows:

[0043] Wastewater enters the filter bag 4 from the inlet pipe 2. Because the filter bag 4 has a small pore size, it can only allow wastewater to pass through, while suspended solids and impurities cannot pass through. Therefore, it can filter and intercept suspended solids and impurities.

[0044] During cleaning, the rotating rod 12 is rotated beforehand, and the valve plate 13 seals the inlet pipe 2. Then, the worker manually removes the tension belt 5 from the inlet pipe 2, and then secures the cleaning port 41 with cable ties 11. Subsequently, the filter bag 4 is lifted upwards by the hanging rope 10, thereby removing the filter bag 4 from the wastewater. After it has drained, the hanging bracket 7 is pushed to move the filter bag 4 closer to the edge of the filter tank 1, thus facilitating the removal and cleaning of the filter bag 4.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
