[0021] Please see Figures 1-3 In this embodiment of the present invention, a large particle impurity filtration device for industrial wastewater treatment is disclosed. The main body of the filtration device is a filter box 1, which is the core container of the entire device, carrying all internal components and providing space for wastewater filtration. A metal conduit 4 is provided at the upper end of the filter box 1, which is responsible for transporting wastewater into the device. Its lower end is fixedly installed on a retaining seat 3, which is a hollow structure to ensure that the wastewater can flow stably and accurately to the filtration area. A lifting and fixing sleeve 6 is installed on one side of the metal conduit 4. The lifting and fixing sleeve 6 consists of a telescopic rod and an installation sleeve. The telescopic rod is installed on the filter box 1, and the installation sleeve is used to fix the inlet pipe 5. The height of the inlet pipe 5 can be adjusted by the telescopic rod to adapt to different wastewater introduction needs, making it convenient to connect with wastewater pipes of different heights. It also facilitates the removal of the inner screen 18. The other end of the inlet pipe 5 is inserted into the interior of the metal conduit 4, thereby realizing the introduction of wastewater.

[0022] The drive motor 2 is located at the upper end of the filter box 1, near the metal conduit 4, and is the power source for the device to achieve high-efficiency filtration. The second gear 10 at the lower end of the drive motor 2 meshes with the first gear 9 at the upper end of the large particle filter screen 11 through the opening of the retaining seat 3. The retaining seat 3 has a hollow structure, and the opening on one side allows the gears to mesh smoothly. When the drive motor 2 starts, it drives the second gear 10 to rotate, which in turn causes the large particle filter screen 11 to rotate through gear transmission. The lower end of the large particle filter screen 11 is mounted on the dispersing grate 13 through the mounting bearing 12. The rotating large particle filter screen 11 and the removable inner screen 18 can effectively intercept large particles of debris in the sewage, while preventing debris from accumulating and clogging the filter screen, thus improving filtration efficiency. When there are many large particles of debris on the removable inner screen 18, it can be removed.

[0023] The large particle filter screen 11 is also equipped with a disassembly inner screen 18. The large particle filter screen 11 has equidistant limiting grooves 20 inside, and the disassembly inner screen 18 has equidistant guide protrusions 19 on its outer wall. The radius of the disassembly inner screen 18 is smaller than that of the large particle filter screen 11, and it has a handle 17 at its upper end. The guide protrusions 19 are inserted into the limiting grooves 20 to achieve limiting and fixing. When the disassembly inner screen 18 needs to be cleaned or replaced, the operator can easily take it out of the large particle filter screen 11 through the handle 17. The operation is convenient and the maintenance difficulty is reduced.

[0024] After initial filtration by the large particle filter 11, the wastewater falls through the large particle filter 11 into the dispersion grate 13 below. The dispersion grate 13 is fixed inside the filter box 1 by a mounting base and has multiple filter holes to evenly disperse the wastewater, allowing it to flow evenly to the activated carbon filter 14 and the pebble filter 15 below. The activated carbon filter 14 utilizes the adsorption properties of activated carbon to adsorb some harmful substances, odors, and small particles in the wastewater, further purifying it. The pebble filter 15 performs the final filtration, intercepting the remaining fine particles and also acting as a buffer and guide. After multiple layers of filtration, the purification level of the wastewater is significantly improved.

[0025] The bottom of the filter box 1 is equipped with a water guide slope 16. The filtered wastewater is guided by the water guide slope 16 to collect in the drain pipe 8 at the bottom of the filter box 1 and discharged through the drain pipe 8 to enter the subsequent wastewater treatment stage. In addition, an observation window 7 is provided on the upper surface of the filter box 1 on one side of the lifting and fixing sleeve 6. The operator can observe the filtration status of the wastewater inside the filter box 1, the water level, and the operating status of each component in real time through the observation window 7, so as to detect and deal with problems in a timely manner.

[0026] The working principle of this utility model is as follows: Industrial wastewater enters the metal conduit 4 through the inlet pipe 5, and is then transported to the retaining seat 3 by the metal conduit 4, falling onto the large particle filter screen 11. The drive motor 2 is started, driving the second gear 10 to rotate. Through gear meshing, the large particle filter screen 11 rotates, and large particles are intercepted on the disassembled inner screen 18. Simultaneously, the rotation process prevents debris from accumulating and clogging the filter screen. If there is a large amount of debris, the inner screen 18 can be disassembled for cleaning. When removal is required, first raise the lifting fixing sleeve 6 so that one end of the inlet pipe 5 exits through the metal conduit... Remove from step 4, then pull the handle 17 on the inner screen 18 to lift it upwards. The wastewater after large particle filtration falls into the dispersion grate 13 through the large particle filter screen 11. The dispersion grate 13 evenly disperses the wastewater. Subsequently, the wastewater passes through the activated carbon screen 14 and the pebble filter screen 15 in sequence. The activated carbon screen 14 adsorbs harmful substances and odors, while the pebble filter screen 15 intercepts the remaining fine particles, achieving deep purification of the wastewater. After multiple layers of filtration, the wastewater is guided by the water guide slope 16 to the drain pipe 8 at the bottom of the filter box 1 and discharged through the drain pipe 8 to enter the subsequent wastewater treatment stage.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
