[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1

[0046] Please see Figure 1-13As shown, this embodiment is an automated environmentally friendly wastewater treatment device, including a treatment box 1 with an opening at the top. Columns 2 are connected to the four corners of the bottom of the treatment box 1. The inner cavity of the treatment box 1 is provided with a sedimentation chamber 3 and a purification chamber 4 from left to right. A support frame 5 is connected to the top left side of the treatment box 1. A cleaning box 6 is connected to the inner wall of the support frame 5. An electric push rod 7 is connected to the left end of the sedimentation chamber 3. An assembly table 8 is connected to the right movable end of the electric push rod 7. A packing frame 9 is inserted into the purification chamber 4. A drainage trough plate 10 is connected to the upper part of the rear side wall of the purification chamber 4. A PLC controller is connected to the outer wall of the treatment box 1.

[0047] The top of the impurity removal box 6 is connected to a water inlet 601. A diversion plate 602 is provided below the opening of the water inlet 601. Arc-shaped plates 603 are connected to the front and rear ends of the diversion plate 602. Filter holes 604 are evenly distributed in the arc-shaped plates 603. A discharge channel 605 is connected between the end of the arc-shaped plates 603 and the impurity removal box 6. A conveying shell plate 606 is connected to the bottom of the inner cavity of the impurity removal box 6. Several filter holes 607 are opened on the bottom wall of the conveying shell plate 606. Discharge pipes 608 are connected to the front and rear sides of the bottom wall of the conveying shell plate 606. The left end of the discharge pipe 608 extends out of the processing box 1.

[0048] Two steering shafts 611 are rotatably connected to the center of the inner cavity of the impurity removal box 6. Multiple scrapers 612 are circumferentially connected to the outer wall of the steering shafts 611. The steering shafts 611 and the arc plate 603 are arranged coaxially. The lower scraper 612 abuts against the upper surface of the arc plate 603. A conveyor motor 613 is connected to the lower part of the outer wall of the impurity removal box 6. The output end of the conveyor motor 613 is connected to a conveyor shaft 614. Spiral augers 615 are symmetrically connected to the front and rear of the outer wall of the conveyor shaft 614. The lower end of the spiral auger 615 abuts against the upper surface of the conveyor shell plate 606.

[0049] The specific embodiments of the present invention are as follows:

[0050] This device is powered by an external power source. The treatment tank 1 is supported and fixed by the column 2. Wastewater is introduced into the impurity removal tank 6 through the inlet hopper 601. The diversion plate 602 guides the wastewater into the arc-shaped plates 603 on both sides. The first filter hole 604 isolates large particles of impurities above the arc-shaped plates 603. As the wastewater falls, it impacts the scraper 612, causing the steering shaft 611 to drive the scraper 612 to rotate. This sweeps the large particles of impurities into the discharge channels 605 on both sides. The wastewater filtered by the arc-shaped plates 603 falls into the bottom conveyor shell 606, where it undergoes secondary filtration through the second filter hole 607. The conveyor motor 613 drives the conveyor shaft 614 to rotate, and the two spiral augers 615 push the impurities isolated on the surface of the conveyor shell 606 to the front and rear sides respectively, so that the isolated impurities are discharged through the discharge pipe 608. This effectively achieves solid-liquid separation, thereby pre-treating the wastewater.

At this time, the docking groove 865 and the docking block 804 are aligned and engaged. The drive motor 803 drives the docking block 804 to rotate, so that the short shaft 863 drives the drive gear 864 to rotate. The drive gear 864 meshes with the spur gear ring 871 on the transmission side, so that the receiving seat 807 drives the filter cartridge 808 to rotate at high speed. After the water enters the filter cartridge 808, it is separated by centrifugal force. Impurities are left in the filter cartridge 808. The water flows out through the filter hole 3 809 and flows into the sedimentation chamber 3 below. The guide strip 881 and the limiting groove 872 are designed to facilitate the installation and removal of the filter cartridge 808 with the receiving seat 807.
