Embodiment

[0022] Please refer to Figures 1 to 4 , the present utility model provides the following technical solutions: A solid-liquid separation device for industrial wastewater treatment, including a solid-liquid separation box 1, middle support square pipes 2 are welded at equal intervals on one side of the middle part inside the solid-liquid separation box 1, a top filter box 5 is installed near the middle support square pipe 2 on one side of the top inside the solid-liquid separation box 1, first filter holes 12 are opened at equal intervals at one end of the top filter box 5, first semi-hanging rings 14 are symmetrically welded on both sides of the inner wall of the top filter box 5 at the top, a plurality of bottom support square pipes 3 are welded on one side of the bottom inside the solid-liquid separation box 1, and the longitudinal section shape formed by the plurality of bottom support square pipes 3 is L-shaped. A bottom filter box 6 is installed near the bottom support square pipe 3 on one side of the bottom inside the solid-liquid separation box 1. Second filter holes 13 are opened at equal intervals at the bottom end and one end of the bottom filter box 6. Second semi-hanging rings 15 are symmetrically welded on both sides of the inner wall of the bottom filter box 6 at the top. Limit plates 4 are symmetrically welded on both sides of the inner wall of the solid-liquid separation box 1 at the bottom. A filter plate 7 is inserted and installed between the two symmetrically arranged limit plates 4. The aperture of the first filter hole 12 is larger than the aperture of the second filter hole 13, and the aperture of the second filter hole 13 is larger than the aperture of the filter plate 7. By the combined use of the top filter box 5, the bottom filter box 6 and the filter plate 7, multi-stage filtration of industrial wastewater can be achieved;

[0023] On one side of the top of the solid-liquid separation tank 1, away from the top filtration tank 5, a U-shaped baffle 16 is installed by bolts. On both sides of the top end of the U-shaped baffle 16, third semi-lifting rings 17 are welded. The use of the U-shaped baffle 16 can prevent industrial wastewater from directly entering the bottom filtration tank 6. At the bottom of one end of the solid-liquid separation tank 1, a drain pipe 8 is welded. At the bottom of one side of the solid-liquid separation tank 1, a square cleaning pipe 9 is welded. In the middle of the top end of the square cleaning pipe 9, a jack 10 is opened. An insertion plate 11 is installed inside the jack 10. The insertion plate 11 and the jack 10 are adapted to each other, which can prevent industrial wastewater from directly discharging through the square cleaning pipe 9.

[0024] The working principle and usage process of the present utility model: Industrial wastewater enters the device through the top filtration tank 5. Through the first filtration holes 12 provided in the top filtration tank 5, larger impurities in the industrial wastewater can be preliminarily filtered and removed. The removed larger impurities will precipitate at the bottom of the top filtration tank 5. Then, the preliminarily filtered industrial wastewater enters the bottom filtration tank 6. Through the second filtration holes 13 provided in the bottom filtration tank 6, smaller impurities in the industrial wastewater can be secondarily filtered and removed. The removed smaller impurities will precipitate and accumulate inside the bottom filtration tank 6. The industrially wastewater after the secondary filtration enters the solid-liquid separation tank 1. When the industrially wastewater after the secondary filtration contacts the filter plate 7, the industrial wastewater can be filtered again, so that the fine impurities in the industrial wastewater can be removed. The industrial wastewater after three times of filtration is discharged from the device through the drain pipe 8;

[0025] After the device has been used for a period of time, the staff removes the U-shaped baffle 16. Then, the user respectively hoists and removes the top filtration tank 5, the bottom filtration tank 6 and the filter plate 7. After flushing and removing the precipitated impurities inside the top filtration tank 5 and the bottom filtration tank 6, the user takes out the insertion plate 11 and flushes the inside of the solid-liquid separation tank 1 with pressurized water to remove the residual impurities inside the solid-liquid separation tank 1. Then, the user reinstalls the filter plate 7, the bottom filtration tank 6, the top filtration tank 5 and the U-shaped baffle 16 to facilitate the repeated use of the device.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
