[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-6 This utility model provides a technical solution for a filtration device for treating dyeing and printing wastewater.
[0032] A filtration device for treating dyeing and printing wastewater includes:
[0033] The filter box 1 has a filter chamber 2 inside. The side wall of the filter chamber 2 has a slot 3. The slot 3 includes an insertion port 4. The insertion port 4 passes through one side of the filter box 1. The upper inner wall of the insertion port 4 has an upper groove 5.
[0034] Filter plate 6 is inserted into slot 3;
[0035] Cover plate 7, cover plate 7 includes upper insertion part 8 and lower insertion part 9, upper insertion part 8 is inserted into upper groove 5, and lower insertion part 9 is inserted into insertion port 4;
[0036] The limiting device limits the cover plate 7.
[0037] The dyeing and printing wastewater enters the filter chamber 2 through the inlet 22 of the filter housing 1. Then, the filter plate 6 filters the wastewater, and the filtered water is discharged from the outlet 23 of the filter housing 1 after passing through the filter holes of the filter plate 6. When the filter plate 6 needs to be replaced, the limiting device releases the limiting device on the cover plate 7, and then the filter plate 6 is removed. At this time, the filter plate 6 can be moved horizontally out of the slot 3. Since the upper groove 5 is located above the insertion port 4, the upper groove 5 will not block the impurities on the upper part of the filter plate 6, thus making it easy to remove the filter plate 6.
[0038] like Figure 4 and Figure 7 As shown, a first sealing ring groove 10 is provided on the outer wall of the cover plate 7, and a first sealing ring 11 is installed in the first sealing ring groove 10. The outer wall of the first sealing ring 11 abuts against the inner wall of the insertion port 4 and the upper groove 5. The first sealing ring 11 thus ensures the sealing between the cover plate 7 and the insertion port 4 and the upper groove 5.
[0039] like Figure 4 As shown, the filter plate 6 is provided with an upward-facing second sealing ring groove 12, and a second sealing ring 13 is installed in the second sealing ring groove 12. The upper end of the second sealing ring 13 abuts against the upper inner wall of the slot 3 and the lower side of the upper insertion part 8. By providing the second sealing ring 13, the sealing between the filter plate 6 and the upper inner wall of the slot 3 and the lower side of the upper insertion part 8 can be increased.
[0040] like Figure 1 and Figure 4 As shown, two guide rails 14 are fixed on the outer wall of the filter box 1. The two guide rails 14 are located on the upper and lower sides of the insertion port 4. A sliding component is installed between the two guide rails 14. The sliding component includes a connecting rod 15, a limiting bolt 16, and two sliders 17. The two sliders 17 are respectively installed on the two guide rails 14. The connecting rod 15 is fixed between the two sliders 17. The connecting rod 15 is provided with a connecting threaded hole 18. The limiting bolt 16 is threadedly connected to the connecting threaded hole 18. The end of the limiting bolt 16 abuts against the side of the cover plate 7 facing away from the filter plate 6, thereby limiting the cover plate 7.
[0041] When it is necessary to disassemble the filter plate 6, first loosen the limiting bolt 16, then move the connecting rod 15. The connecting rod 15 can move relative to the guide rail 14 through the slider 17, thereby moving the limiting bolt 16 to the side of the cover plate 7. At this time, the cover plate 7 can be disassembled, which is very convenient.
[0042] like Figure 4 As shown, the cover plate 7 is provided with a limiting groove 20 for the end of the limiting bolt 16 to be inserted. When the end of the limiting bolt 16 is inserted into the limiting groove 20, the lateral movement of the limiting bolt 16 can be restricted, thereby better limiting the cover plate 7.
[0043] like Figure 1 As shown, there are two sliders, and both sliders can limit the position of the cover plate 7.
[0044] like Figure 1 As shown, the two ends of the guide rail 14 extend out of the side of the filter box 1, and a connecting side rod 21 is fixed between the ends of the two guide rails 14. When it is necessary to insert the cover plate 7, the limiting bolt 16 can be moved to the end of the guide rail 14, and the connecting side rod 21 can prevent the slider 17 from falling off the guide rail 14.
[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
