Description

Technical Field

[0001] The utility model relates to the field of wastewater pretreatment equipment, in particular to a high-salinity industrial wastewater combined treatment equipment. Background Art

[0002] High-salinity industrial wastewater refers to industrial wastewater containing high concentrations of salt, mainly from various industrial production processes such as chemical, pharmaceutical, petroleum, papermaking, dairy processing, and food canning. This type of wastewater not only contains high concentrations of organic pollutants, but also is accompanied by a large amount of calcium, sodium, chlorine, sulfate ions, etc. The salt content usually exceeds 1% of the total salt content, or even higher. When treating high-salinity industrial wastewater, the wastewater first passes through a grid or screen to remove large suspended particles and floating objects. Then, the wastewater may enter the regulator to effectively regulate the water quality and quantity, and increase the dissolved oxygen (DO) in the water through aeration to provide suitable conditions for subsequent biochemical processes.

[0003] Existing high-salinity industrial wastewater combined treatment equipment is generally composed of filter boxes and regulators and other equipment. These components work together to achieve efficient and stable wastewater treatment. The filter box is usually equipped with filter plates with different pore sizes to achieve effective filtration of particles of different sizes in the wastewater. First, the wastewater passes through the large-pore filter plate to quickly remove large particle impurities and suspended matter in the wastewater, and then it is finely filtered through the small-pore filter plate to further remove tiny particles and suspended matter, thereby improving the clarity and quality of the wastewater. However, the filter plate is usually fixed to the inside of the filter box by bolts. When the filter plate needs to be removed for replacement, cleaning or maintenance, the filter box must be disassembled first so that the filter plate can be accessed and removed from the fixed position. This method increases the difficulty of maintenance work and increases manpower and time costs.

[0004] Therefore, it is necessary to provide a new high-salinity industrial wastewater combined treatment equipment to solve the above technical problems. Utility Model Content

[0027] In the specific implementation process, Figure 1-Figure 8 As shown, a high-salinity industrial wastewater combined treatment equipment includes a filter box 1 and a cover plate 2 arranged on the filter box 1. Two filter plates 3 with different apertures are arranged in the filter box 1. The two filter plates 3 are both engaged in the slots 4 opened on the cover plate 2 and the slots 5 opened on the filter box 1 through a snap-fit ​​assembly. The upper end of the filter plate 3 is adapted to the slot 4 of the cover plate 2, and the side wall of the filter plate 3 is adapted to the slot 5 of the filter box 1. The snap-fit ​​assembly includes a knob 6, a snap-fit ​​plate 7 and a first spring 8. The snap-fit ​​plate 7 is movably arranged in a first mounting groove 9 opened on the cover plate 2 and moves in the first mounting groove 9. A first snap-fit ​​groove 11 matching the snap-fit ​​plate 7 is opened at the upper end of the inner wall of the first mounting groove 9. The knob 6 movably passes through the cover plate 2 and is fixedly connected to one side of the upper end of the snap-fit ​​plate 7. One end of the snap-fit ​​plate 7 can rotate in a second mounting groove 10 opened at the upper end of the filter plate 3. A second engaging groove 12 matching one end of the card plate 7 is provided, and one end of the first spring 8 is fixedly connected to the first mounting groove 9 opened inside the cover plate 2, and the upper end of the first spring 8 is in contact with the bottom side of the card plate 7 and applies a thrust thereto. When the filter plate 3 needs to be disassembled for replacement, cleaning or maintenance, the knob 6 is first pressed downward, and the knob 6 applies pressure to the first spring 8 and descends, and the card plate 7 slides out of the first engaging groove 11 on the cover plate 2 and the second engaging groove 12 on the filter plate 3. At this time, the rotating knob 6 drives the card plate 7 to move in the first mounting groove 9 in the cover plate 2 and the second mounting groove 10 in the filter plate 3 until the card plate 7 slides out of the second mounting groove 10. At this time, the card plate 7 does not limit the filter plate 3, and the filter plate 3 is ejected from the slot 4 by the thrust applied by the second spring 18 and the movable plate 19, and the filter plate 3 can be drawn out from the slot 4 of the cover plate 2 and the slot 5 in the filter box body 1;

[0028] The two filter plates 3 are respectively provided with large-aperture sieve holes and small-aperture sieve holes. Through the filter plates 3 with different pore sizes, effective filtration of particles of different sizes in the wastewater can be achieved. First, the wastewater passes through the large-aperture filter plate 3 to quickly remove large particle impurities and suspended matter in the wastewater, and then passes through the small-aperture filter plate 3 for fine filtration to further remove tiny particles and suspended matter, thereby improving the clarity and quality of the wastewater. Two handles 13 are provided on the upper ends of the two filter plates 3, so that the operator can easily grab and move the filter plates 3;

[0029] A water inlet 15 and a drain outlet 14 are respectively provided on the side walls of the filter box 1. The water inlet 15 is connected to a water suction pump 17 through a conduit. A regulating valve 16 is provided on the drain outlet 14. The drain outlet 14 is connected to a regulator 22 through a conduit. The regulator 22 can effectively regulate the water quality and quantity, and increase the dissolved oxygen in the water through aeration, so as to provide suitable conditions for subsequent biochemical processes.

[0030] A plurality of second springs 18 are provided on the bottom wall of the card slot 5 provided on the filter box body 1, and a movable plate 19 is fixedly connected to the plurality of second springs 18. A drainage groove 20 is provided on one side of the card slot 5, so that when the filter plate 3 is installed, waste water in the card slot 5 can be discharged along the drainage groove 20;

[0031] Both sides of the bottom end of the cover plate 2 and both sides of the upper end of the filter box 1 are provided with multiple bolt holes for bolts 21 to install and fix them. The cover plate 2 is tightly fixed to the upper end of the filter box 1 by bolts 21 to ensure that the structure is stable and reliable, not easy to loosen or move, and prevent industrial wastewater leakage.

[0032] The working principle of the utility model is as follows: when the filter plate 3 needs to be disassembled for replacement, cleaning or maintenance, the knob 6 is first pressed downward, the knob 6 applies pressure to the first spring 8 and descends, and the card plate 7 slides out of the first engaging groove 11 on the cover plate 2 and the second engaging groove 12 on the filter plate 3. At this time, the knob 6 is rotated to drive the card plate 7 to move in the first mounting groove 9 in the cover plate 2 and the second mounting groove 10 in the filter plate 3 until the card plate 7 slides out of the second mounting groove 10. At this time, the card plate 7 does not limit the filter plate 3, and the filter plate 3 is pushed out by the thrust applied by the second spring 18 and the movable plate 19. The filter plate 3 pops up from the slot 4, and the filter plate 3 can be pulled out from the slot 4 of the cover plate 2 and the slot 5 in the filter box 1. After the filter plate 3 is disassembled, when the filter plate 3 is replaced, cleaned or repaired, the filter plate 3 is inserted into the slot 4 and the slot 5, and a thrust is applied to the movable plate 19 and the second spring 18 to make them descend, and the knob 6 is turned to make the card plate 7 snap into the second installation slot 10. When the card plate 7 is rotated to a certain angle, the first spring 8 applies a thrust to the card plate 7 and the knob 6 to make the card plate 7 rise and snap into the first snap groove 11 and the second snap groove 12, thereby completing the limiting of the filter plate 3.
