Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a system for treating and recycling washing wastewater from a printing and dyeing process. Background Art

[0002] The printing and dyeing enterprises produce wastewater that is "treated according to quality and reused in different categories". The "pretreatment + eMBR + ozone flotation" process is used to treat alkali reduction wastewater and de-boiling and bleaching wastewater. The treated water meets the water requirements of the boiling process. A multi-stage membrane system is used to selectively separate dyeing wastewater, and the concentrated brine is recovered and reused in the dyeing process. The "pretreatment + biochemical + reverse osmosis" method is used to treat washing wastewater, and the concentrated liquid is returned to the dyeing wastewater multi-stage membrane system. The clear liquid meets the water requirements of the washing process. A wastewater treatment and reuse model is established to achieve the purpose of recycling printing and dyeing wastewater.

[0003] In the process of the reuse system, the wastewater is oxidized and decomposed in the aerobic tank by the microorganisms in the activated sludge, which is an important step in the treatment of printing and dyeing wastewater. In order to meet the growth needs of the microorganisms in the aerobic tank, oxygen is continuously blown into the aerobic tank through a special pipeline in the prior art. However, the oxygen blowing point in the prior art is relatively single, resulting in uneven distribution of the blown oxygen in the aerobic tank, poor effect of oxygen blowing, and impurities that are difficult to decompose are easily dispersed in the tank, making collection and treatment more difficult.

[0004] In view of the above, we provide a printing and dyeing process washing wastewater treatment and reuse system to solve the above problems. Summary of the invention

[0005] In view of the above situation, the present invention provides a printing and dyeing process washing wastewater treatment and reuse system. The exhaust pipe designed in the system rotates downward to open and closes upward. The oxygen discharged from the exhaust pipe can cover a large area of ​​impurities accumulated on the main network, allowing them to be fully mixed.

[0006] A system for treating and reusing washing wastewater from a printing and dyeing process, comprising a box body, a lifting frame is slidably provided at the middle part of the box body, an opening mechanism is provided inside the box body, the opening mechanism comprises a rotating frame, a vertical rod, a main net and a secondary net, the rotating frame is rotatably provided inside the box body, the bottom of the rotating frame is overlapped with a vertical rod, the bottom of the vertical rod is provided with a spacer column, the vertical rod is slidably provided at the bottom of the box body, a reverse bar is rotatably provided on one side of the lifting frame, a reset spring is provided on the outer side of the rotating frame, a No. 1 bar is slidably provided in the middle part of the lifting frame, a control spring is provided between the No. 1 bar and the lifting frame, the middle part of the reverse bar is attached to the No. 1 bar, and an exhaust mechanism is provided above the lifting frame.

[0007] The above technical solution has the following beneficial effects:

[0008] The exhaust pipe is rotated downward to open and upward to close. The oxygen discharged from the exhaust pipe can cover the impurities accumulated on the main net in a large range, make them fully mixed, and can be blown into the inside of the box to form a stir. Driven by the liquid stir, the precipitated impurities can easily pass through the main net to the bottom of the box. The main net can be shaken, which is also convenient for reaching the bottom of the box. While fully mixing the oxygen, the sediment on the main net is blown to the bottom for deep treatment. After the floating frame is driven downward by the vertical rod, one side of the floating plate contacts the bottom of the box, making the floating plate horizontal. The floating plate can form a flat plate to drive the deposited material upward, and then release the floating plate when it reaches a certain position, causing the deposited material to fall, and the floating plate is tilted so that the deposited material fully reacts with the ejected oxygen when it falls.

DETAILED DESCRIPTION

[0021] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figures 1 to 11 It can be clearly presented in the detailed description of the embodiments that the structural contents mentioned in the following embodiments are all referenced to the drawings in the specification.

[0022] This embodiment provides a system for treating and recycling wastewater from dyeing and printing processes, as shown in the attached Figure 1-11 As shown in the instruction manual, Figure 1 This is the overall structure diagram of this scheme. Figure 1 It can be seen that the two sides of the rotating frame 3 are restricted in angle. Figure 2 In the instruction manual Figure 1 The box 1 is cut along the center at one end on the basis of the manual, so it is not a cross-sectional view in the traditional sense. Figure 3 Taken from the instruction manual Figure 2 , Instructions attached Figure 4 Switch the unique perspective of the instruction manual 1, the instruction manual is attached Figure 5 Taken from the instruction manual Figure 4 The bottom of the manual is attached Figure 6 Cutting is performed along the direction of the side hole 26, so the cutting surface is oblique. Figure 7 Cut the lifting frame 2 along the horizontal surface. Figure 8 Taken from the instruction manual Figure 7 , Instructions attached Fig. 9 Cut along the center of the two exhaust pipes 13, the instructions are attached Fig.10 The exhaust pipe 13 is suspended and displayed. Since the exhaust pipe 13 is long, only one side is taken. Fig.10The floating frame 24 is displayed in the air. This solution has two core structures. The first is the lifting frame 2, and the second is the floating frame 24. This paragraph mainly introduces the lifting frame 2. The lifting frame 2 is slidably arranged inside the box body 1, and the lower side extends to the outside of the box body 1, that is, a hole corresponding to the sliding of the lifting frame 2 is opened at the bottom of the box body 1, and the two are sealed and slidable. The up and down movement of the lifting frame 2 is through the control push rod 32, and the control push rod 32 is a kind of electric push rod. The control push rod 32 is shown as not suspended in the figure, but it is not actually, because the box body 1 is placed on the ground, and the ground does not move. The lower end of the control push rod 32 needs to be installed on the ground, which is equivalent to being installed on the box body 1, and the lifting frame 2 is installed on the protruding end of the control push rod 32, so that the lifting frame 2 can move up and down along the box body 1, and a reverse bar 9 is arranged at the bottom of the lifting frame 2 for rotation, as shown in the attached manual Figure 5As shown, there is a torsion spring at the rotation center of the reverse bar 9. The elastic force of this torsion spring is relatively large and it is not easy to twist. The reverse bar 9 can only be rotated when it cannot pass through, and the other side of the reverse bar 9 touches the vertical rod 4. The upper part of the vertical rod 4 overlaps the rotating frame 3. The lower part of the rotating frame 3 has a notch responsible for overlapping with the vertical rod 4, so that the vertical rod 4 can move up and down to rotate the rotating frame 3, and the side of the rotating frame 3 is limited in direction of rotation, so that the rotating frame 3 can only rotate downward and cannot rotate upward, which also makes the vertical rod 4 can only move downward and cannot move upward The rotating frame 3 is provided with a control spring 12 at the edge thereof. The control spring 12 is a torsion spring. The purpose is to maintain the rotating frame 3 in a horizontal state, and the rotating frame 3 can be rotated and reset after rotation. When the box 1 is precipitated, the accumulated impurities are easily accumulated on the top of the rotating frame 3. The main net 5 and the auxiliary net 6 are slidingly arranged on the top of the rotating frame 3, but the sliding directions of the main net 5 and the auxiliary net 6 are different. The main net 5 and the auxiliary net 6 are compressed by springs between the rotating frame 3, so that the auxiliary net 6 can contact the inside of the box 1, and the two corresponding main nets 5 on the left and right are closed, that is, the vertical pipe cannot move. The lifting frame 2 can only move upward, so that when the lifting frame 2 moves upward, the reverse bar 9 rotates downward, and the reverse bar 9 moves downward, and the middle part will tilt upward. The reverse bar 9 tilts toward the middle and does not squeeze the second bar 14 upward, and the second bar 14 tilts upward and does not move. The lifting frame 2 continues to move upward and passes through the main net 5 to move upward, because there is a certain interval between the main nets 5, that is, the main nets 5 are not tightly closed together under the action of the spring, and the top of the lifting frame 2 is pointed, so that the main net 5 can be pushed open during the upward movement and pass through the main net 5. Arriving at the top, this is the whole process of the lifting frame 2 moving upward, and the lifting frame 2 reaching the main net 5 and moving downward is the core structure of this solution. As mentioned above, the upward movement cannot make the vertical rod 4 move upward (because of the unidirectional rotation of the rotating frame 3), but the downward movement can make the vertical rod 4 move downward. The lifting frame 2 moves downward firstly so that the reverse bar 9 drives the spacer column 8 (there are multiple spacer columns 8, and the spacer column 8 is equivalent to the vertical rod 4) to move downward, so that the rotating frame 3 rotates downward and controls the spring 12 to twist. However, since the rotation angle of the rotating frame 3 to the bottom is limited (as shown in the attached manual), the lifting frame 2 can move downward. Figure 1As shown, there is a rotation gap at the edge of the rotating frame 3, and this gap is the rotation angle of the limited rotating frame 3), that is, the downward movement distance of the vertical rod 4 is limited, so the reverse bar 9 has to be pressed down toward the middle, and a No. 1 bar 11 is just arranged in the middle of the reverse bar 9, and the No. 1 bar 11 is supported by the control spring 12, so that the No. 1 bar 11 moves downward, and the No. 1 bar 11 is meshed with the internal gear 33 on the top, and the No. 2 bar 14 is meshed on the other side of the internal gear 33, so that the No. 2 bar 14 moves upward. The effect of the reverse bar 9 after rotation is introduced first. After the reverse bar 9 rotates, the vertical rod 4 will be released, and the vertical rod 4 and the rotating frame 3 will be quickly reset under the reset of the control spring 12, so as to achieve the effect of shaking the main net 5 and the auxiliary net 6. Impurities are deposited on the auxiliary net 6, so that the impurities can be shaken, and the rotating frame 3 rotates and can tilt downward, so that the impurities can easily reach the bottom of the box 1 for mixing. This is the meaning of the shaking of the rotating frame 3, and the No. 2 bar 14 moves upward to enable the exhaust pipe 13 to rotate downward. The exhaust pipe 13 is rotatably set on one side of the lifting frame 2, and one end of the exhaust pipe 13 is air-intake, and the surface of the air-intake end is rotatably set on the supply pipe 15. The supply pipe 15 penetrates from the bottom of the rotating frame 3 to one side of the exhaust pipe 13, and the supply pipe 15 and the exhaust pipe 13 are rotatably sealed, so that the exhaust pipe 13 can supply gas while rotating. There is a horizontal round block on the top of the No. 2 bar 14, which is on one side of the rotation center of the exhaust pipe 13, as shown in the attached manual Figure 3 and 10 As shown in the figure, a bar is arranged in the middle of the exhaust pipe 13, just above the second bar 14, so that the second bar 14 moves upward to make the two exhaust pipes 13 rotate downward. Since the bar on one side of the middle of the exhaust pipe 13 is shorter, as the second bar 14 continues to move upward, it will break away from the contact with the bar (the return of the second bar 14 will make the exhaust pipe 13 pressed in the reverse direction, so that the exhaust pipe 13 rotates upward and then breaks away from the reset level. The top sliding space of the second bar 14 is very large, and it is not as Figure 3 The exhaust pipe 13 is then released, and the exhaust pipe 13 is reset under the action of the rotating spring 16. In summary, the exhaust pipe 13 will first rotate toward the bottom and then reset. Since the exhaust pipe 13 of the box discharges oxygen, if oxygen is discharged during the rotation process, it will cause impurities in the box body 1 to be chaotic. Therefore, the control block 17 is designed in this scheme under this consideration. A support spring 19 is provided on one side of the control block 17. The control block 17 is slidably arranged at one end of the exhaust pipe 13, and a sliding control valve 18 is provided on one side of the supply pipe 15. As shown in the attached manual Fig. 9 At this time, the control valve 18 is closed, that is, no gas is supplied to the exhaust pipe 13. One side of the control valve 18 extends to the outer wall of the supply pipe 15. A sliding strip needs to be opened on one side of the supply pipe 15, and the control valve 18 is designed to block the sliding strip, as shown in the attached manual. Fig. 9and 10 As shown, the sealing of the supply pipe 15 is ensured. As mentioned above, under the action of the second strip 14, the exhaust pipe 13 will first rotate downward, so that the control block 17 is pressed down along the upper side of the arc strip on the outside of the control valve 18 (the control valve 18 extends to the outside of the supply pipe 15 as an arc strip), that is, the control valve 18 moves toward the exhaust pipe 13, so that the control valve 18 is opened at the first time of rotation. As the exhaust pipe 13 continues to rotate downward, it becomes larger and larger, and when it reaches the maximum angle of rotation, it will pass over the arc strip, and at this time the support spring 19 will pull back the control block 17, so that the control block 17 can smoothly reach the left bottom of the arc strip when returning, and then push the arc strip upward in the process of returning, which is also That is, closing the control valve 18. Since the rotating spring 16 is released quickly, the process of closing the control valve 18 is shorter, and the degree of internal chaos is smaller. Here is an introduction to the effect. This is equivalent to rotating the exhaust pipe 13 downward to open the exhaust pipe 13 and closing it upward. In this way, the oxygen discharged from the exhaust pipe 13 can cover the impurities accumulated on the main net 5 in a large range, so that they are fully mixed, and can be blown into the inside of the box 1 to form a stir. Note that it is a stir. Driven by the liquid stir, the precipitated impurities can easily pass through the main net 5 to the bottom of the box 1, and the main net 5 can be shaken, which is also convenient for reaching the bottom of the box 1. This is the core effect of this solution. While fully mixing the oxygen and blowing the sediment on the main net 5, it reaches the bottom for deep treatment;

[0023] The previous paragraph introduces the core effect of this solution. This paragraph introduces the floating plate 25. Since the exhaust pipe 13 is horizontal in a normal state (one side of the exhaust pipe 13 has densely packed small holes, and oxygen is ejected from the small holes), and the supply pipe 15 continues to supply when the control valve 18 is closed, the supply pipe 15 will supply toward the oblique channel 21, as shown in the attached manual. Figure 8 As shown, after the control valve 18 extends outward (through the supply pipe 15, the supply pipe 15 and the control valve 18 are sealed and slidable), a top valve 20 is integrally provided in the middle, and a buffer ring 23 is sealed and slidably provided on one side of the top valve 20. At this time, the buffer ring 23 does not block the entrance end of the oblique channel 21, and it will be blocked as long as it moves slightly. The buffer spring 22 is only used to increase a buffer zone, so that switching between channels is formed, that is, the oblique channel 21 is opened during the upward movement of the lifting frame 2. The previous paragraph introduced that the vertical rod 4 will move up and down to reset, and a floating frame 24 is overlapped in the middle of the vertical rod 4 (as shown in the attached manual Figure 2 As shown, columns extend on both sides of the vertical rod 4 and overlap the floating frame 24, so the floating frame 24 also moves up and down. Figure 6 and 11The floating frame 24 is limited to slide at the bottom of the box body 1, so that the floating frame 24 can move up and down, and a floating plate 25 is rotatably arranged on the floating frame 24, and an angle spring is arranged between the floating plate 25 and the floating frame 24. The angle spring is attached to the specification. Figure 6 The first enlarged section on the right is shown, but it is not numbered. The angle spring is also a torsion spring. When the floating plate 25 is not subjected to external force, it is in an inclined state. The inclined state of the floating plate 25 is when the side hole 26 and the nozzle hole 27 correspond. Once the floating plate 25 rotates, the two do not correspond, that is, the side tube 7 does not supply oxygen to the nozzle hole 27. The principle of the side tube 7 and the supply pipe 15 is that one end needs to be flexibly connected to the oxygen equipment so that the oxygen can be transported to the inside of the box 1 (such as inputting oxygen into the inside of the box 1 through a pump). The side tube 7 supplies to the rotation center of the floating plate 25, and a side hole 26 is opened on one side as shown in the attached manual. Figure 6 As shown, the side hole 26 corresponds to the spray hole 27 to form an oxygen spray. When the floating frame 24 is driven downward by the vertical rod 4, one side of the floating plate 25 contacts the bottom of the box body 1, making the floating plate 25 horizontal, and then automatically fixes the floating plate 25. The floating plate 25 can form a flat plate to drive the deposited objects upward, and then release the floating plate 25 when it reaches a certain position, so that the deposited objects fall, and the floating plate 25 is tilted so that the deposited objects fully react with the sprayed oxygen when they fall. To achieve these effects, the present solution is provided with a positioning groove 28 on one side of the floating plate 25, and a positioning frame 29 is horizontally slidably provided on one side of the floating frame 24, and an extendable positioning block 30 is provided on one side of the positioning frame 29 (a spring is provided between the positioning frame 29 and the positioning block 30 for support). Under the pushing movement of the bottom of the box body 1, the positioning block 30 is stuck in the positioning groove 28, that is, the floating plate 25 is stuck, so that the floating plate 25 is horizontal, until it contacts the release block 31 during the upward movement. The release block 31 is integrally arranged inside the box body 1. The bottom of the release block 31 is an inclined surface, and the top of the positioning frame 29 is also an inclined surface. The two inclined surfaces are parallel, so that the release block 31 pushes the positioning block 30 away from the floating plate 25, that is, the floating plate 25 is released. This is the principle of the positioning frame 29. The floating plate 25 is controlled to rotate by the bottom of the box body 1, so that the positioning frame 29 positions the floating plate 25, showing that the moving top is below the release block 31 and detaches from the floating plate 25. The floating plate 25 is reset and cut off under the action of the angle spring, and the spray hole 27 is reopened. The instruction manual is attached Figure 6The enlarged image on the lower right is the positioning block 30. A spring is also arranged between the positioning frame 29 and the floating frame 24, so that the positioning frame 29 moves toward the floating plate 25, jams the floating plate 25, and automatically approaches the floating plate 25 after the principle release block 31. A lifting frame 2 is slidingly arranged in the middle of the box body 1, and an opening mechanism is arranged inside the box body 1. The opening mechanism includes a rotating frame 3, a vertical rod 4, a main net 5 and a secondary net 6. The rotating frame 3 is rotatably arranged inside the box body 1.
