Detailed Implementation

[0030] 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.

[0031] Please see Figure 1-13 This utility model provides a technical solution: a wastewater graded treatment system, including a first filter box 1, a second filter box 2 disposed at the lower end of the first filter box 1, and a drain pipe 3 disposed at the lower end of the second filter box 2 for drainage, and further including:

[0032] The cleaning mechanism 5 is located inside the first filter box 1 and is used to clean impurities in the first filter box 1.

[0033] The receiving box 4 is detachably installed above the drain pipe 3 in the second filter box 2, and is used to collect the impurities filtered in the second filter box 2.

[0034] It should be noted that during operation, when purifying wastewater, the wastewater is added to the first filter box 1 for preliminary filtration. After primary filtration, the wastewater flows into the second filter box 2 for secondary filtration. Then, the wastewater after tiered filtration is discharged from the drain pipe 3 to enter the next stage of treatment. While the wastewater is being treated in the first filter box 1, the cleaning mechanism 5 is opened to remove impurities from the first filter box 1 and discharge them. After a period of use in the second filter box 2, the receiving box 4 is removed from one side of the second filter box 2 to clean the impurities collected inside. This system, by setting up the first filter box 1 and the second filter box 2, can perform tiered treatment of wastewater. The first filter box 1 initially filters out larger impurities in the wastewater, while the second filter box 2 further filters out smaller impurities, resulting in more thorough purification of the wastewater and improving the quality and efficiency of wastewater treatment. A drain pipe 3 is installed at the lower end of the second filter box 2, and a detachable receiving box 4 is installed above the drain pipe 3 to collect the impurities filtered in the second filter box 2. This design makes drainage and impurity collection more reasonable, avoiding secondary pollution caused by impurities being discharged with the wastewater, and also facilitating the cleaning and centralized treatment of impurities. The cleaning mechanism 5 is located inside the first filter box 1 and can automatically clean the impurities in the first filter box 1. Compared with the traditional manual cleaning method, this automated cleaning mechanism 5 greatly improves the cleaning efficiency and saves manpower and time costs.

[0035] In one embodiment, the first filter box 1 includes an inclined outer box 101, a support frame 13 disposed at the lower end of the outer box 101 for supporting the outer box 101, and an inner box 102 disposed inside the outer box 101. A feed guide plate 11 is disposed on the downward inclined side of the outer box 101, and a collection box 12 is disposed on the other side of the outer box 101. A water inlet 1011 is opened on the side of the outer box 101 connected to the feed guide plate 11, and a slag discharge port 1012 is opened on the side of the outer box 101 connected to the collection box 12. A filter hole 1021 is opened on the inner box 102, and the lower end of the outer box 101 is open.

[0036] This design is for reference. Figure 4-6 The outer casing 101 is provided with a feed guide plate 11 on its downward-sloping side, and an inlet 1011 is provided on the side of the outer casing 101 connected to the feed guide plate 11. This design allows sewage to flow smoothly into the outer casing 101 along the feed guide plate 11, avoiding splashing and backflow of sewage at the inlet, improving the efficiency and stability of sewage introduction, and ensuring that the entire sewage treatment system can operate continuously and stably. The outer casing 101 is tilted, and after the sewage enters the outer casing 101, the cleaned sewage can easily flow into the next stage second filter box 2 under the action of gravity. As the impurities move towards the side closer to the slag discharge port 1012, the water remaining in the impurities can be easily discharged, which helps to initially separate the impurities from the sewage and creates favorable conditions for subsequent finer filtration treatment. The inner casing 102 is located inside the outer casing 101, and a filter hole 1021 is provided on the inner casing 102. Wastewater enters the inner box 102 and undergoes finer filtration through the filter holes 1021. It is then discharged from the lower end of the outer box 101 into the second filter box 2. Impurities can enter the collection box 12 through the slag discharge port 1012, which realizes the centralized collection of impurities, facilitates the subsequent cleaning and treatment of impurities, and also avoids the accumulation of impurities inside the outer box 101, which would affect the normal operation of the filter box.

[0037] In one embodiment, the cleaning mechanism 5 includes a motor 51 disposed on the upper end of the support frame 13, a rotating shaft 52 disposed on the power output end of the motor 51 and passing through the support frame 13, a connecting frame 53 disposed on the side of the rotating shaft 52 away from the motor 51, a rotating ring 54 disposed on the outside of the connecting frame 53, and a spiral blade 103 disposed inside the inner box 102. The rotating ring 54 is connected to the inner box 102, and a protective box 14 for protecting the motor 51 is disposed on the support frame 13.

[0038] This design is for reference. Figure 4-8The motor 51 drives the rotating shaft 52 to rotate, which in turn drives the connecting frame 53, the rotating ring 54 and the inner box 102 to rotate. The spiral blades 103 are set inside the inner box 102. When the rotating shaft 52 drives the inner box 102 to rotate, the spiral blades 103 rotate accordingly, causing impurities to move towards the slag discharge port 1012 inside the inner box 102 and finally enter the collection box 12. This cleaning method can reduce the residue of impurities in the inner box 102 and improve the cleaning effect.

[0039] In one embodiment, the second filter box 2 includes a water collection chamber 21 with an upper opening disposed at the lower end of the outer box 101 and communicating with the outer box 101, and a filter screen 22 disposed inside the water collection chamber 21 and disposed at an angle. The receiving box 4 is disposed on the side of the water collection chamber 21 away from the collecting box 12.

[0040] This design is for reference. Figure 12 The water collection chamber 21 of the second filter box 2 is connected to the outer box 101 of the first filter box 1, and receives the sewage after the initial filtration of the first filter box. The inclined filter screen 22 inside the water collection chamber 21 can further finely filter the sewage and remove smaller impurity particles. This double-layer filtration structure, namely the initial filtration of the first filter box 1 and the fine filtration of the second filter box 2, can significantly improve the water quality after sewage treatment, so that the treated water meets higher discharge standards or reuse requirements. The inclined filter screen 22 makes it easy for impurities to slide to one side under the action of gravity, reducing the accumulation of impurities on the filter screen 22 and extending the service life of the filter screen 22.

[0041] In one embodiment, the water collection tank 21 is provided with a support roller 55 for supporting the inner tank 102.

[0042] This design is for reference. Figure 12 The support roller 55 can disperse these pressures and prevent the inner box 102 from being deformed due to excessive local stress. The support roller 55 can evenly distribute the pressure to multiple contact points to ensure the stability of the shape of the inner box 102. In the process of sewage treatment, the flow of water and the operation of filtration equipment may generate vibrations. The support roller 55 can reduce the swaying amplitude of the inner box 102 in the vibration environment and enhance the stability of the inner box 102.

[0043] In one embodiment, the receiving box 4 includes a sealing plate 41, a fixing plate 43 disposed at the lower end of the sealing plate 41, mounting plates 211 disposed on both sides of the water collection tank 21, guide rods 45 disposed on both sides of the sealing plate 41 and passing through the mounting plates 211, and a limiting plate 451 disposed on the side of the guide rods 45 away from the sealing plate 41. The sealing plate 41 is fixedly connected to the mounting plates 211 by fixing bolts 44, and the fixing plate 43 is fixedly connected to the water collection tank 21 by bolts. A handle 42 is provided on the side of the sealing plate 41 away from the water collection tank 21.

[0044] This design is for reference. Figure 9-13 The receiving box 4 is fixedly connected to the mounting plates 211 on both sides of the water collection tank 21 by the fixing bolts 44 on the sealing plate 41. This design makes the installation and disassembly of the receiving box 4 simple and quick. When it is necessary to clean the impurities in the receiving box 4, simply loosen the fixing bolts 44 to remove the receiving box 4 from the water collection tank 21. Similarly, during installation, the receiving box 4 can be quickly fixed to the water collection tank 21, which greatly improves maintenance efficiency and reduces equipment downtime. The guide rods 45 set on both sides of the sealing plate 41 pass through the mounting plates 211. The guide rods 45 play a positioning and guiding role. When installing the receiving box 4, the guide rods 45 can ensure that the sealing plate 41 is accurately aligned with the mounting plates 211, avoiding problems such as poor sealing or shaking of the receiving box 4 due to installation position deviation.
