DETAILED DESCRIPTION

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The filter box 301 is provided with a diverter box 301, which is installed at the upper end of the interior of the filter box 1. A plurality of nozzles 302 are installed at the lower end of the interior of the diverter box 301. A connecting pipe 303 is installed through the upper end of the interior of the filter box 1, and the lower end of the connecting pipe 303 is connected to the diverter box 301. A fixed block 304 is installed through the upper end of the interior of the filter box 1 and close to the liquid inlet pipe 2. One end of the fixed block 304 is located inside the filter box 1 and is movably located at the upper end of the interior of the rotating drum 4. A groove 305 is provided on the upper surface of the fixed block 304, and the groove 305 coincides with the second filter screen 6 and the nozzle 302 up and down. A conveyor belt 310 is installed at the lower end of the interior of the groove 305. An inclined block 307 is installed at the end of the fixed block 304 away from the filter box 1. A discharge trough 308 is provided inside the inclined block 307, and the discharge trough 308 is connected to the groove 305.

[0027] like Figure 4 and Figure 6 As shown, several limit blocks 7 are installed inside the separation tank 5, and the limit blocks 7 are respectively fitted with the side of the second filter screen 6 close to the liquid inlet pipe 2. Annular chutes 10 are respectively provided on both sides of the rotating cylinder 4, and several support frames 9 are respectively installed at both ends of the interior of the filter box 1, and the ends of the support frames 9 close to each other are respectively engaged and installed inside the annular chutes 10.

[0028] The stopper 7 prevents the second filter screen 6 from deflecting during rotation, ensuring filtration accuracy. It also serves to push and transport impurities, improving impurity removal efficiency. The cooperation between the annular chute 10 and the support frame 9 ensures more stable rotation of the rotating drum 4, reducing vibration and noise during operation.

[0029] like Figures 4 to 7 As shown, a drainage groove 306 is provided inside the groove 305 and at the lower end of one side close to the drainage pipe 12. The drainage groove 306 is parallel to the conveyor belt 310. A plurality of placement grooves 311 are provided on the surface of the conveyor belt 310. The first filter screen 312 is installed inside the placement grooves 311 respectively. A baffle 309 is installed on the upper side of the end close to the discharge groove 308 and the groove 305. A temporary storage box 314 is installed inside the groove 305 and at one end close to the discharge groove 308.

An air intake pipe 317 is installed at the front end of the discharge trough 308, and the rear end of the air intake pipe 317 is connected to the temporary storage box 314. A scraper 313 is installed between the groove 305 and the discharge trough 308, and the upper end of the scraper 313 is in contact with the surface of the conveyor belt 310.

[0030] After the impurities are washed down to the conveyor belt 310 by the high-pressure water flow, the water flows through the first filter 312 on the conveyor belt 310 for filtration. The filtered liquid then flows back to the rotating drum 4 through the drainage trough 306 for further filtration, thus realizing water recycling and improving water resource utilization. The design of the first filter 312 and the drainage trough 306 ensures the filtration effect.

[0031] The baffle 309 is set above the connection between the discharge trough 308 and the groove 305 to prevent impurities from splashing. The high-pressure gas in the temporary storage box 314 is ejected through the exhaust groove 316 of the triangular protrusion 315, and the scraper 313 scrapes to push the impurities on the conveyor belt 310 into the interior of the discharge trough 308 for unloading. The air inlet pipe 317 transports high-pressure gas into the temporary storage box 314 to provide power for the exhaust groove 316. The baffle 309 ensures the directional discharge of impurities and improves the discharge efficiency. The high-pressure gas blowing and the scraping of the scraper 313 are combined to form a dual power to ensure that the impurities are completely discharged and realize automatic cleaning.

[0032] The working principle of this environmental protection wastewater filtration device:

[0033] During use, sewage first enters the interior of the rotating drum 4 through the liquid inlet pipe 2, and then the motor 8 drives the rotating drum 4 to rotate, so that it drives the second filter screen 6 in the drum to rotate synchronously, and then the sewage can be filtered through the second filter screen 6, and the filtered liquid is allowed to flow into the lower end of the filter box 1 and discharged through the drain pipe 12. After the impurities are intercepted by the second filter screen 6, they move upward with the rotation of the second filter screen 6. At the same time, the limit block 7 cooperates with the second filter screen 6 to push the impurities until the impurities reach the bottom of the recovery mechanism 3. Then, when the impurities rotate to the bottom of the recovery mechanism 3 with the filter screen, the nozzle 302 in the diversion box 301 is connected to the nozzle 302 through the connecting pipe 30 3 is connected to a high-pressure water source, and the water flow is sprayed to flush the surface of the second filter screen 6, so that impurities are separated from the second filter screen 6 and fall onto the surface of the conveyor belt 310 below. Then, after the water is filtered by the first filter screen 312 on the conveyor belt 310, it returns to the rotating drum 4 through the drainage trough 306 and is filtered again, thus realizing the recycling of water resources. Then, when the conveyor belt 310 drives the impurities to move to the side of the scraper 313, the air inlet pipe 317 delivers high-pressure gas into the temporary storage box 314. The gas is ejected through the exhaust groove 316 of the triangular protrusion 315, and cooperates with the scraper 313 to form a dual power, pushing the impurities into the discharge trough 308 for discharge.

[0034] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
