[0003] In the prior art, there is an invention patent disclosed in the publication number: CN109354291B, a printing and dyeing wastewater treatment equipment, which relates to the field of wastewater treatment technology.

The filtering device includes a first tank body, a blower and a second motor, and a first fixed plate is fixed to the inner wall of the first tank body. The present invention uses a blower to send external air into the first tank body along a plurality of first slots on the airbag, thereby achieving stirring of the wastewater, and cooperates with the first motor to drive a plurality of fan blades to rotate slowly, so that the wastewater in the first tank body is stirred more fully, and then the oil agent is easy to float up and flow out along the oil drain pipe, and the stirring process is conducive to the adjustment of acid and alkali, so that the acid and alkali adjustment treatment effect in the wastewater is better;

[0004] Although the above equipment can treat printing and dyeing wastewater, it only filters solid and semi-solid wastewater through normal gravity and filter plates, and the cleanliness of the filtration is insufficient.

[0005] Another example is the invention patent disclosed in the publication number: CN114751554B, a wastewater treatment device for printing and dyeing wastewater, including a bottom plate and a support ring, the support ring is fixedly arranged on the bottom plate; a treatment box, fixedly arranged in the support ring and with discharge ports on both sides, the two sides of the treatment box are respectively connected to an inlet pipe and an outlet pipe; a separation mechanism, installed in the treatment box, the printing and dyeing wastewater can be separated into solid and liquid through the separation mechanism; a sedimentation mechanism, fixedly arranged in the treatment box and arranged on one side of the separation mechanism, the sedimentation mechanism is fixedly provided with an opening and closing stirring mechanism, a power output end of the opening and closing stirring mechanism and the sedimentation mechanism are arranged in coordination.

[0062] Working principle: Figure 1Before use, the staff can connect the wastewater delivery pipe with the feed conduit 13 to facilitate the subsequent continuous delivery of the printing and dyeing wastewater to the mixing box 8. At the same time, various wastewater treatment agents, such as flocculants or regulators, can be simultaneously introduced into the mixing box 8, thereby facilitating the subsequent comprehensive treatment of the printing and dyeing wastewater. Figure 3 and Figure 4 , the staff can connect the printing and dyeing wastewater discharge pipe with the material discharge pipe 35 to facilitate the discharge operation of the treated wastewater and facilitate re-treatment;

[0063] like Figure 1 , Figure 4 and Fig.12 When the printing and dyeing wastewater is preliminarily treated, the staff can start the servo motor 10. At this time, the servo motor 10 can drive the transmission card shaft 1 to rotate. At the same time, the transmission card shaft 1 can synchronously drive the guide turntable 625, the transmission turntable 626, the guide gear 66 and the sealing rotating seat 36 at the bottom to rotate. When the above-mentioned transmission card shaft 1 rotates, the transmission card shaft 1 can drive the multiple groups of mixing blades 9 on the side to fully mix the printing and dyeing wastewater and various treatment agents inside the mixing box 8, so as to treat and neutralize various harmful substances in the wastewater, and then complete the preliminary treatment of the printing and dyeing wastewater;

[0064] like Fig.12 and Fig.14 , the staff can treat different volumes of printing and dyeing wastewater in equal amounts according to different types. When adjusting the volume of wastewater discharged from the wastewater storage tank 63, the staff can start the reduction motor 624. The reduction motor 624 can drive the ball slide 622 to move forward and backward inside the guide turntable 625 through the ball screw 623. By adjusting the distance between the ball slide 622 and the fixed slide shaft 621 and the center of the guide turntable 625, the fixed slide shaft 621 drives the liquid guide sealing push plate 627 to move sideways in a cycle through the guide rail 628, thereby adjusting the volume of printing and dyeing wastewater discharged in equal amounts from the wastewater storage tank 63;

[0065] like Figure 2 , Fig.12 , Fig.13 and Fig.14 , when the above-mentioned preliminary treated wastewater is subjected to an equal amount of deep treatment, if Fig.14The above-mentioned transmission card shaft 1 can synchronously drive the guide turntable 625 at the bottom to rotate, and the guide turntable 625 can synchronously drive the transmission turntable 626 at the bottom to rotate through the internal ball slide 622 and the fixed slide shaft 621. At the same time, when the fixed slide shaft 621 rotates in a circle under the drive of the guide turntable 625 and the transmission turntable 626, the fixed slide shaft 621 can pass through the sliding limit with the guide slide rail 628, and then synchronously drive the guide slide rail 628 to perform cyclic lateral displacement, so that the guide slide rail 628 can synchronously drive the liquid guide sealing push plates 627 on both sides to perform cyclic displacement inside the wastewater storage tank 63. In the initial state, the fixed slide shaft 621 is located at the limit of one side. At this time, the liquid guide sealing push plate 627 on this side is located inside the wastewater storage tank 63 near the second one-way liquid guide valve 64. When the liquid guide sealing push plate 627 is displaced toward the other side driven by the guide slide rail 628, as shown in FIG. Figure 2 and Fig.13 At this time, negative pressure is generated inside the wastewater storage tank 63 on this side, the first one-way liquid guide valve 2 located at the input end of the wastewater guide pipe 7 on the same side is opened, and the second one-way liquid guide valve 64 on this side is closed, so that the printing and dyeing wastewater that has been preliminarily treated inside the mixing box 8 can be introduced into the wastewater storage tank 63 along the wastewater guide pipe 7. When the liquid guide sealing push plate 627 on this side is reset again, the inside of the wastewater storage tank 63 is in a high-pressure state. At this time, the first one-way liquid guide valve 2 is closed, and the second one-way liquid guide valve 64 is opened, so that the printing and dyeing wastewater inside the wastewater storage tank 63 can be introduced into the wastewater treatment tank 54 in equal amounts through the fixed guide pipe 535;

[0066] like Figure 1 , Figure 8 and Fig. 9 When the liquid-guiding sealing push plate 627 guides the printing and dyeing wastewater from the wastewater storage tank 63, the printing and dyeing wastewater is sequentially introduced into the sealing seat 531 through the fixed guide tube 535, and then filtered layer by layer through the filter press screen 532 inside the sealing seat 531, and finally introduced into the wastewater treatment tank 54. Since there are a variety of reagents mixed with the printing and dyeing wastewater inside the mixing box 8, various floccules and large particles will be produced. The multi-layer filter press screen 532 can fully filter various impurities under high hydraulic pressure filtration, thereby improving the treatment efficiency of wastewater;

[0067] like Figure 3 , Figure 8 and Fig. 9 When the wastewater storage tank 63 on this side introduces the printing and dyeing wastewater into the wastewater treatment tank 54, the wastewater treatment tank 54 can discharge the previous group of wastewater through the liquid outlet conduit 55. When the above wastewater is introduced into the wastewater treatment tank 54, Fig.13The above-mentioned circularly rotating 526 can synchronously drive the guide gear 66 at the bottom to rotate, and the guide gear 66 can synchronously drive the six groups of transmission gears 52 on the side to rotate synchronously, so that the transmission gear 52 can drive the filter adsorption plate 51 at the bottom to rotate inside the wastewater treatment tank 54, so as to adsorb harmful substances in the printing and dyeing wastewater after the filter press treatment. At the same time, the printing and dyeing wastewater inside the three groups of wastewater treatment tanks 54 on both sides is alternately transported, which can provide sufficient time for wastewater treatment;

[0068] like Figure 2 , Figure 4 and Figure 5 The treated wastewater is introduced into the collection box 33 through the liquid outlet conduit 55 and the sealing card groove 32. At this time, when the guide gear 66 is rotating, it can drive the sealing rotating seat 36 and the wastewater centrifugal drum 37 to rotate through the transmission shaft 65, so that the wastewater inside the wastewater centrifugal drum 37 can be centrifugally rotated in contact with the side wall. Since the sealing rotating seat 36 is rotatably connected to the collection box 33, the wastewater introduced into the collection box 33 is introduced into the wastewater centrifugal drum 37 through the liquid inlet guide groove 311 inside the sealing rotating seat 36. With the high-speed centrifugation of the wastewater centrifugal drum 37, due to the different densities and masses of various impurities in the wastewater, the impurities of various printing and dyeing wastewaters are concentrated at the bottom and middle of the sealing bottom cover 38, and the upper layer of the clear liquid after centrifugation is introduced into the wastewater collecting drum 34 through the drainage groove 39. The wastewater collecting drum 34 can discharge the printing and dyeing wastewater after centrifugation through multiple sets of discharge conduits 35.
