Technical Field

[0001] This utility model relates to the technical field of rainwater and sewage treatment equipment, specifically to a rainwater and sewage purification and storage tank. Background Technology

[0002] Rainwater and wastewater purification is a crucial aspect of urban water cycle management. Rainwater carries sediment, garbage, and air pollutants as it falls and flows across the ground; wastewater includes domestic and industrial wastewater, which is complex in composition and heavily polluted. During purification, large particles are first intercepted by screens, and then sediment is allowed to settle in sedimentation tanks. Subsequently, biological treatment technology is used, employing microorganisms to decompose organic matter. For wastewater, further advanced treatment is required, such as filtration and disinfection, to remove residual pollutants and pathogens. Purified rainwater can be reused for green space irrigation and road washing, while wastewater can be discharged in compliance with standards or reused.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figures 1 to 4 In this embodiment, a rainwater and sewage purification and storage tank includes a tank body 1. A sludge removal pipe 2 is fixedly installed on one side of the tank body 1. The bottom end of the sludge removal pipe 2 extends to the inner bottom wall of the tank body 1. A sludge removal assembly is installed inside the tank body 1.

[0025] The dredging component includes a sliding cleaning slider 3 that is slidably installed on the bottom wall of the pool body 1. The cleaning slider 3 has a guide slope 31 on the side near the dredging pipe 2 and an arc-shaped concave surface on the side near the dredging pipe 2. Two cleaning screws 4 are rotatably installed on the inner wall of the pool body 1 and are threadedly connected to the cleaning slider 3.

[0026] Secondly, two threaded through holes 32 are provided on one side of the cleaning slider 3, and the threaded through holes 32 are adapted to the cleaning screw 4.

[0027] Specifically, the rotation of the cleaning screw 4 drives the cleaning slider 3 to move, pushing the sludge inside the pool 1 towards the cleaning pipe 2. This facilitates the collection of sludge that cannot be extracted to the cleaning pipe 2, allowing the sludge to be extracted. This reduces the steps required to move the cleaning pipe 2 and improves the convenience of sludge removal.

[0028] Please see Figure 1 and Figure 2 In this embodiment, a transmission box 5 is fixedly installed on one side of the pool body 1, and two transmission sprockets 6 are rotatably installed on the inner side wall of the transmission box 5.

[0029] The transmission sprocket 6 is fixedly connected to one end of the cleaning screw 4, and the two transmission sprockets 6 are connected by chain drive.

[0030] Secondly, a cleaning motor 7 is fixedly installed on one side of the pool body 1, and the output shaft of the cleaning motor 7 is fixedly connected to one end of one of the cleaning screws 4. The cleaning motor 7 drives one of the cleaning screws 4 to rotate, which in turn drives two transmission sprockets 6 to rotate synchronously via a chain, thereby driving the two cleaning screws 4 to rotate synchronously and moving the cleaning slider 3.

[0031] Please see Figure 1 In this embodiment, a sludge pump 8 is fixedly installed on one side of the pool body 1. The input end of the sludge pump 8 is fixedly connected to one end of the sludge cleaning pipe 2, and the output end of the sludge pump 8 is fixedly installed with a sludge discharge pipe 9. When the sludge pump 8 is started, it draws sludge from the sludge cleaning pipe 2 and discharges it through the sludge discharge pipe 9.

[0032] A water intake pipe 10 is fixedly installed on one side of the pool body 1, and a water intake valve 11 is fixedly installed on the surface of the water intake pipe 10. An overflow pipe 12 is fixedly installed on one side of the pool body 1, and a water collection hopper 13 is fixedly installed on the top of the pool body 1. Rainwater collected in the pool body 1 is taken through the water intake pipe 10. When there is too much rainwater, it is discharged from the overflow pipe 12 into the next pool body 1.

[0033] Please see Figure 3 In this embodiment, a filter cylinder 14 is fixedly installed at the bottom of the water collection hopper 13. Filter holes 15 are fixedly installed on the surface of the filter cylinder 14. An mounting plate 16 is fixedly installed on the top of the filter cylinder 14. A water inlet hole 17 is opened on the top of the mounting plate 16, and a handle 18 is fixedly installed on the top of the mounting plate 16. Rainwater entering the pool 1 is discharged to the filter cylinder 14 through the water collection hopper 13, filtering out impurities in the rainwater. The impurities remain in the filter cylinder 14. When cleaning is required, the filter cylinder 14 is lifted out through the handle 18 for cleaning.

[0034] The working principle of the above embodiment is as follows: the cleaning motor 7 drives the two cleaning screws 4 to rotate, which in turn drives the cleaning slider 3 to move, pushing the sludge inside the pool 1 toward the cleaning pipe 2. This makes it easier to concentrate the sludge that cannot be extracted to the cleaning pipe 2. The cleaning pump 8 then extracts the sludge, reducing the steps of moving the cleaning pipe 2 and improving the convenience of sludge removal.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
