Description

[0002] Printing wastewater is industrial wastewater generated in the fabric printing process of the textile printing and dyeing industry, mainly from color matching sizing, equipment washing, post-treatment and special processes. Its pollutant composition is complex, including active dyes, disperse dyes and other organic matter containing chromophore groups, starch, PVA and other sizing agents, and urea, soda ash and other auxiliaries, with characteristics of high concentration of organic pollutants, strong alkalinity and high color. Some processes such as engraving wastewater may contain heavy metals such as hexavalent chromium, which are highly toxic and carcinogenic. If not effectively treated and directly discharged, it will cause water eutrophication, heavy metal accumulation, destroy aquatic ecosystems, and threaten human health through the food chain.

[0003] Small printing plant wastewater treatment relies on wastewater treatment and recycling devices, which generally need to go through the links of chemical mixing, filter press filtration and acid-base adjustment. However, in actual use, the printing wastewater contains fibers, which can easily cause blockage of the pipeline or inlet and outlet during the transmission of the printing wastewater, making the transmission of the printing wastewater not smooth. In addition, after the existing wastewater is added with chemicals, a large amount of flocculent material is generated, which has a low flow rate when being transmitted to the filter press, making the filtration speed of the filter press slow. Moreover, the residue discharge structure of the filter press is usually expanded through filter cloth, but the flocculent material has high viscosity after being squeezed, which can easily adhere to the filter cloth, possibly reducing the residue discharge efficiency of the filter press.

[0052] S4: when disassembling the filter press mechanism 9 and the drive mechanism 10, the water in the stirring filter barrel 1 is discharged, then the fixed screw 15 is rotated out of the second screw sleeve 16, then the filter ring network 4 is extracted to complete the disassembly, installation is the same reason.

[0053] Working principle: when using the present application, waste water and medicament are injected into the left side of the partition plate 2, and waste water is extracted from the right side of the partition plate 2. Under the action of the shape and water pressure at the bottom of the stirring filter barrel 1, the waste water enters the right side of the partition plate 2 from the left side of the partition plate 2 through the flow-through hole 3 and the filter ring network 4. The stirring motor 701 is started, and the output shaft of the stirring motor 701 drives the first stirring shaft 702, the connecting block 703 and the second stirring shaft 704 to rotate, thereby forming a vortex of waste water on the left side of the partition plate 2. When the second stirring shaft 704 rotates, the gear 803 rotates around the gear ring 804, thereby driving the gear 803 to rotate, and driving the winding drum 801 and the winding rod 802 to rotate. At this time, the winding rod 802 will wind the fibers in the waste water vortex by rotating.

[0054] The waste water enters the filter ring network 4, and the flocculation in the waste water is intercepted by the filter ring network 4. The drive motor 1002 is started, and the drive motor 1002 drives the drive screw 1003 to rotate. Through the thread action between the first screw sleeve 1005, the sliding block 1004 is lowered, so that the hinge rod 1006 gradually becomes horizontal, thereby driving the connecting rod 906 and the compression plate 907 to move to the right. At this time, the guide rod 904 moves in the guide groove 902, the control rod 905 moves in the discharge groove 903 and the T pipe 908, the compression plate 907 pushes the impurities and waste water in the filter ring network 4 to move to the compression frame 901. In the process of compression, the waste water is filtered out of the filter ring network 4. Until the control rod 905 no longer closes the lower side of the T pipe 908, at this time the compression plate 907 is located at the left side of the compression frame 901 and closes the right side of the filter ring network 4. Under the action of pressure, impurities are discharged through the T pipe 908 to the sewage guide frame 909, and reset the same reason.

[0055] When disassembling the winding mechanism 8, the lower pressing gear 803 is pressed, at this time the gear 803 is no longer engaged with the gear ring 804, the movable rod 806 is movable in the loading cylinder 805 and the spring 807 is compressed, then the winding cylinder 801 is lifted, so that the limiting rod 814 is separated from the limiting groove 815, until the spacing between the winding rods 802 is greater than the second stirring shaft 704, the winding cylinder 801 is transversely moved to complete the disassembly, and the installation is the same.

[0056] When disassembling the pressure filtration mechanism 9 and the driving mechanism 10, the water in the stirring and filtering barrel 1 is discharged, then the fixed screw rod 15 is screwed out of the second screw sleeve 16, then the filtering ring net 4 is pulled out to complete the disassembly, and the installation is the same.
