Description

Technical Field

[0001] The utility model belongs to the technical field of printing and dyeing, and particularly relates to a printing and dyeing wastewater filtering device. Background Art

[0002] Printing and dyeing, also known as dyeing and finishing, refers to the chemical treatment of textile materials (fibers, yarns, and fabrics). Dyeing and finishing, along with spinning, weaving, or knitting, form the entire textile production process. Printing and dyeing wastewater refers to wastewater discharged during the pretreatment, dyeing, printing, and finishing of cotton, wool, linen, silk, chemical fibers, or blended products. It contains large amounts of complex components such as dyes, sizing agents, and surfactants, and exhibits high chroma, high organic matter concentrations, strong alkalinity, and significant variability in water quality and volume. Therefore, it requires treatment before discharge.

[0003] Patent publication number CN217526585U discloses a printing and dyeing wastewater filtration device for printing and dyeing. The utility model discloses a printing and dyeing wastewater filtration device for printing and dyeing, including a filter box and a treatment box.

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0030] See also Figures 1-6 , the utility model provides a technical solution for a printing and dyeing wastewater filtering device.

[0031] A printing and dyeing wastewater filtering device, a filtering support frame 1;

[0032] The filter box 2 is fixed on the filter support frame 1. The filter box 2 is provided with a filter cavity 3. The filter cavity 3 penetrates the upper and lower sides of the filter box. The two sides of the filter box 2 are respectively provided with a wastewater inlet hole 4 and a wastewater outlet hole 5. A plurality of filter screens 6 are installed in the filter cavity 3.

[0033] A lifting bracket 7 is fixed on the filter support frame 1;

[0034] A lifting device 8 is fixed on the lifting bracket 7;

[0035] The filter bottom plate 9 is fixed on the lifting device 8. The lifting device 8 drives the filter bottom plate 9 to move up and down to open or close the lower opening of the filter cavity 3.

[0036] As the filtration time is long, more impurities will accumulate on the filter bottom plate 9. In the non-filtering state, the lifting device 8 drives the filter bottom plate 9 to move downward, and opens the lower opening of the filter chamber 3. This makes it easy to hang down the impurities accumulated on the filter bottom plate 9, quickly remove the impurities, and clean the impurities very conveniently.

[0037] like Figure 1 As shown, it includes a receiving frame 10, which is arranged below the filter bottom plate 9. The receiving frame 10 is provided with a receiving groove 11 with an upward opening. The receiving groove 11 can receive the scraped impurities and can better collect the impurities.

[0038] The filtering device further comprises a transverse moving device 12 , which is mounted on one side of the filtering bottom plate 9 . A vertical moving device 13 is mounted on the transverse moving device 12 , and a scraping device 14 is provided on the vertical moving device 13 .

[0039] like Figure 1-Figure 5 As shown, the scraper device 14 includes a fixed rod 15, a telescopic rod 16, a scraper rod 17 and a telescopic spring 18. The fixed rod 15 is fixed on the vertical moving device 13. A slide groove 19 is provided in the fixed rod 15. A lower groove 20 is provided on the lower side of the slide groove 19. The telescopic rod 16 is installed in the slide groove 19. The scraper rod 17 is fixed on the telescopic rod 16. The scraper rod 17 extends out of the lower groove 20. The telescopic spring 18 is arranged between the upper side wall of the slide groove 19 and the telescopic rod 16.

[0040] When the lifting device 8 drives the filter bottom plate 9 to move downward, the vertical movement device 13 drives the scraper 17 to abut against the upper side of the filter bottom plate 9. At this time, the telescopic spring 18 is in a compressed state, and then the transverse movement device 12 drives the scraper 17 to move horizontally to scrape off the impurities above the filter bottom plate 9, making cleaning very convenient. The length of the filter bottom plate 9 is longer than the filter box 2. Figure 6 As shown, when the filter bottom plate 9 closes the lower opening of the filter chamber 3, the scraper device 14 can move to the outside of the filter box 2. The telescopic spring 18 is in a compressed state to ensure that the scraper rod 17 is in close contact with the upper side of the filter bottom plate 9.

[0041] like Figure 1-Figure 4 As shown, the transverse movement device 12 includes two transverse movement seats 21, a transverse movement screw 22, a transverse movement motor 23 and a transverse movement screw block 24. The two transverse movement seats 21 are fixed on one side of the filter base plate 9. The transverse movement screw 22 is rotatably connected between the two transverse movement seats 21. The transverse movement motor 23 is fixed on one of the transverse movement seats 21. The rotating shaft of the transverse movement motor 23 is fixedly connected to one end of the transverse movement screw 22. The transverse movement screw block 24 is threadedly connected to the transverse movement screw 22.

[0042] A vertical moving bracket 25 is fixed on the transverse moving screw block 24 . The vertical moving device 13 includes a vertical moving electric push rod fixed on the vertical moving bracket 25 . The fixing rod 15 is fixedly connected to the push rod of the vertical moving electric push rod.

[0043] The transverse motor 23 drives the transverse screw 22 to rotate. The rotation of the transverse screw 22 can drive the transverse screw block 24 to move horizontally, thereby driving the vertical bracket 25 and the vertical electric push rod to move horizontally. The extension and retraction of the vertical electric push rod can drive the fixed rod 15 to move up and down.

[0044] The lifting device 8 is configured as a lifting electric push rod, which is fixed on the lifting bracket 7. The push rod of the lifting electric push rod is fixedly connected to the filter bottom plate 9, and the lifting electric push rod can drive the filter bottom plate 9 to move up and down.

[0045] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
