Technical Field

[0001] This utility model belongs to the field of wastewater treatment, specifically a wastewater tank filtration and sludge removal system. Background Technology

[0002] During factory production, the cutting of packaging film generates small strips of plastic that scatter on the ground. When cleaning equipment or the ground, these plastic strips flow into a 5-ton wastewater transfer tank. If these plastic scraps are not properly disposed of, they can easily clog the transfer pumps and pipes. Especially during rainy weather, the plastic scraps in the wastewater network may overflow and backflow into lower-lying areas, causing environmental problems. Utility Model Content

The middle section of the wastewater treatment tank is divided into three parts: an inlet tank, an intermediate tank, and a drainage tank, separated by two partitions. Liquid level sensors are installed on the inlet tank, intermediate tank, and drainage tank. A primary filtration device is placed in the inlet tank and discharged into a recovery frame through a first pipe. A recovery frame and a secondary filtration device are installed in the intermediate tank, and the secondary filtration device is discharged into a tertiary filtration frame through a second pipe. A tertiary filtration frame and a sewage discharge assembly are installed in the drainage tank.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model can intercept plastic waste of different sizes by using filter devices with different density pore sizes.

[0013] 2. This utility model uses an automatic liquid level control system to monitor the liquid level of the sewage tank through a high-precision liquid level sensor.

Detailed Implementation

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] like Figure 1 As shown, this utility model provides a sewage tank filtration and sludge removal system, including a sewage treatment tank 1, a sewage inlet pipe 2, and a discharge water network 8. The sewage treatment tank 1 has a sewage inlet pipe 2 installed in the middle of one end. The middle part of the sewage treatment tank 1 is provided with three parts: an inlet tank, an intermediate tank, and a drainage tank, which are separated by two partitions in the middle. Liquid level sensors are installed on the inlet tank, the intermediate tank, and the drainage tank. A primary filtration device is placed in the inlet tank, and the primary filtration device is discharged to a recovery frame 4 through a first pipe 33. The intermediate tank is provided with a recovery frame 4 and a secondary filtration device, and the secondary filtration device is discharged to a tertiary filtration frame 6 through a second pipe 53. The drainage tank is provided with a tertiary filtration frame 6 and a sewage discharge assembly.

[0019] The primary filtration device includes a primary filter frame 31 and a first sewage pump 32. The primary filter frame 31 houses the first sewage pump 32, which can perform preliminary filtration on the sewage entering the first sewage pump 32. The outlet end of the first sewage pump 32 is connected to a first pipe 33, and the first sewage pump 32 transports the sewage through the first pipe 33.

[0020] The secondary filtration device includes a secondary filter frame 51 and a second sewage pump 52. The second sewage pump 52 is placed inside the secondary filter frame 51. The secondary filter frame 51 performs secondary treatment on the sewage. The drainage end of the second sewage pump 52 is connected to and assembled with a second pipe 53.

[0021] The sewage discharge assembly includes a drainage pump 7 and a discharge water network 8. The drainage outlet of the drainage pump 7 is equipped with the discharge water network 8. The drainage pump 7 discharges the treated water through the discharge water network 8, which extends through the wall of the sewage treatment tank 1 to the outside.

[0022] The mesh density of the primary filter frame 31, the secondary filter frame 51, and the tertiary filter frame 6 gradually increases, thereby gradually improving the filtration effect on plastic waste edges and thus gradually enhancing the filtration effect.

[0023] The partition of the sewage treatment tank 1 is equipped with a secondary filter overflow port 9 and a tertiary filter overflow port 10, which are respectively connected to the inlet tank, the intermediate tank and the drainage tank, effectively preventing the water level in the inlet tank and the intermediate tank from becoming too high.

[0024] The mesh density of the tertiary filter overflow port 10 is greater than that of the secondary filter overflow port 9, ensuring that the plastic waste floating on the overflowing sewage is removed, further ensuring the efficiency of sewage filtration and preventing plastic waste from floating on the overflowing sewage.

[0025] Working Principle: The sewage outlet of the factory workshop is connected to the sewage inlet pipe 2. After sewage is discharged from the sewage outlet, it is transported to the inlet pool of the sewage treatment tank 1. The sewage entering the inlet pool is filtered by the primary filter frame 31 and the filtered sewage is transported to the recycling frame 4 for recycling. At the same time, the sewage with lower density is transported to the intermediate pool and filtered by the secondary filter frame 51. Then, it is transported by the first sewage pump 32 to the tertiary filter frame 6 for further filtration. Thus, the capture of plastic waste edges of different sizes is achieved through multi-stage filtration. This application installs a liquid level sensor in the sewage treatment tank 1, which can monitor the liquid level in the sewage treatment tank 1 with high precision. When the liquid level reaches the preset value, the system automatically starts the pump to drain the water. When the liquid level drops to a safe value, the pump automatically stops. At the same time, a secondary filter overflow port 9 and a tertiary filter overflow port 10 are set to avoid the problem of plastic waste edge overflow and ensure the filtration efficiency of sewage treatment.
