Detailed implementation manners

[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0023] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a sewage treatment device for textile printing and dyeing waste provided by an embodiment of the present invention, the sewage treatment device for textile printing and dyeing waste includes:

[0024] The aggregate box 1 is provided with a base 18 inside. A rotating mechanism is installed on the base 18, and a filter screen 16 is installed on the rotating mechanism. A plurality of elastic support ribs 17 are installed on the filter screen 16. A connecting ring is arranged at the core of the filter screen 16. The aggregate box 1 is connected with a flow dividing valve 10 through a fixed bracket 5. A sewage pump 6 is fixedly installed on the flow dividing valve 10. The sewage pump 6 is used to convey sewage to the flow dividing valve 10. A plurality of flow dividing components are arranged on the flow dividing valve 10. The flow dividing components are used to convey sewage downward from multiple directions. A lifting component is also fixedly installed at the bottom of the flow dividing valve 10. The lifting component is rotationally connected with the connecting ring and is used to drive the connecting ring to lift and lower.

[0025] In the embodiment of the present invention, when sewage treatment is carried out, the sewage containing floc is pumped by the sewage pump 6. The sewage enters the flow dividing valve 10. The flow dividing valve 10 evenly distributes the sewage to each flow dividing component. The flow dividing components are used to discharge the sewage downward. The discharging angle of the flow dividing components can be adjusted. By setting the lifting component, the position of the connecting ring can be changed. When the connecting ring is in the lowest position, the whole filter screen 16 is in the shape of a funnel with an open upper part and a closed lower part, which is defined as the first extreme state. When the connecting ring is in the highest position, the whole filter screen 16 is in the shape of an inverted funnel with a closed upper part and an open lower part, which is defined as the second extreme state. During the normal filtering process, it is in the first extreme state. The filter screen 16 is driven to rotate by the rotating mechanism. The sewage discharged from the upper flow dividing component is relatively fixed. The sewage enters the filter screen 16. Under the rotation of the filter screen 16, a centrifugal force is generated, enabling the sewage to quickly pass through the filter holes, while the floc in the sewage remains in the filter screen 16, which can improve the filtering speed. As the floc further increases, the filtering effect of the filter screen 16 will weaken. At this time, the rotation speed can be further increased to enhance the filtering effect. A liquid level sensor is arranged at the connecting ring. When it is detected that the liquid level exceeds the preset value, it is determined that the current filtering effect of the filter screen 16 has decreased to the preset threshold, and the floc inside needs to be cleaned. At this time, the filter screen 16 is controlled to enter the second extreme state. At this time, the rotation speed is increased. Under the action of the centrifugal force, the floc on the filter screen 16 will break away from the filter screen and be thrown onto the aggregate box 1, realizing the process of automatic discharging. Subsequently, it continues to return to the first extreme state for continuous operation.

[0026] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, as a preferred embodiment of the present invention, the rotating mechanism includes a first motor 22 and a rotating bracket 19. The first motor 22 is arranged inside the base 18. A mandrel 21 and multiple groups of rotating brackets 19 are fixedly connected to the output shaft of the first motor 22. A control box 24 is fixedly installed at one end of the rotating bracket 19 away from the first motor 22. A set of guide shafts are fixedly installed inside the control box 24. The cross-section of the guide shaft is polygonal. A set of sliding seats 25 are slidably arranged on the guide shaft. The cross-section of the inner cavity of the sliding seat 25 is the same as that of the guide shaft. A first spring 27 and a second spring 28 are sleeved on the guide shaft. The first spring 27 and the second spring 28 are respectively located on both sides of the sliding seat 25. A clamping plate 26 is fixedly installed on the sliding seat 25. A support ring 20 is clamped and fixed on the clamping plate 26. The outer edge of the filter screen 16 is fixedly installed on the support ring 20. The cross-section of the mandrel 21 is polygonal. A hollow tube 15 is slidably sleeved on the mandrel 21. The cross-section of the inner cavity of the hollow tube 15 is the same as that of the mandrel 21. A connecting ring is fixedly installed on the outer wall of the hollow tube 15. The hollow tube 15 is rotatably connected to the lifting assembly through a bearing. One end of the elastic support rib plate 17 is fixedly connected to the support ring 20, and the other end is fixedly connected to the connecting ring. The sliding seat 25 is made of magnetic material.

[0027] In this embodiment, during filtration, the connecting ring is controlled to move downward to reach the first limit state. The first motor 22 is started. The first motor 22 drives the mandrel 21 and the rotating bracket 19 to rotate synchronously. The rotating bracket 19 will drive the control box 24 to rotate. The control box 24 drives the clamping plate 26 to rotate through the sliding seat 25. The clamping plate 26 drives the support ring 20 to rotate. At the same time, the mandrel 21 will drive the hollow tube 15 to rotate synchronously. The connecting ring is fixed on the hollow tube 15. Therefore, the angular velocities of the connecting ring and the support ring 20 are the same. The filter screen 16 is located between the connecting ring and the support ring 20 and will rotate synchronously. The sewage above falls into the filter screen 16. The sewage passes through the filter screen 16, while the floc remains in the filter screen 16. During this process, the liquid level in the filter screen 16 is monitored by a liquid level sensor. The higher the liquid level, the weaker the current filtering effect of the filter screen 16. When the liquid level reaches a certain height, it means that the filtering effect of the filter screen 16 no longer meets the requirements. At this time, the lifting assembly drives the connecting ring to move upward to reach the second limit state. At this time, the filter screen 16 presents an inverted funnel shape. By controlling the rotation of the filter screen 16, the floc accumulated on the filter screen 16 can be discharged under the action of centrifugal force. The floc contains moisture, so it will fly out along the tangent of the rotation direction of the filter screen 16 and finally enter the aggregate box 1, and then continue to enter the first limit state;

[0028] Whether it is the first limit state or the second limit state, the elastic support rib plate 17 is in a straight state without bending. During the process of switching from the first limit state to the second limit state, the elastic support rib plate 17 will bend. Due to the presence of floc, the elastic support rib plate 17 will bend downward. When reaching the second limit state, under the tensile force of the connecting ring and the support ring 20, it will return to the straight state again, controlling the filter screen 16 to rotate. As the rotation speed increases, the floc on the filter screen 16 is subject to a centrifugal force radially outward along the filter screen 16, that is, the floc no longer exerts a downward pressure on the filter screen 16. At this time, the electromagnet 23 is started, and the electromagnet 23 is controlled to repel the sliding seat 25, prompting the sliding seat 25 to move toward the side close to the hollow tube 15. At this time, the sliding seat 25 will push the elastic support rib plate 17 to bend upward through the support ring 20, making the generatrix of the filter screen 16 bend upward, thereby increasing the curvature of the generatrix to promote the detachment of the floc from the filter screen 16. Under the action of the first spring 27 and the second spring 28, when the electromagnet 23 is not started, the sliding seat 25 will remain in the neutral position, and at this time the support ring 20 does not deform. During the filtering process, as the weight of the floc increases, the elastic support rib plate 17 will cause the filter screen 16 to deform downward. At this time, the electromagnet 23 is controlled to attract the sliding seat 25, thereby increasing the support force of the filter screen 16 and preventing it from deforming.

[0029] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, as a preferred embodiment of the present invention, the lifting assembly includes a second motor, the second motor is fixedly installed in the mounting seat 8, the output shaft of the second motor is fixedly connected with a screw rod 12, a plurality of guide rods 11 are fixedly installed on the mounting seat 8, a lifting seat 13 is slidably arranged on the guide rods 11, the lifting seat 13 is connected with the hollow tube 15 through a bearing, and a threaded hole is arranged on the lifting seat 13, and the screw rod 12 is connected with the lifting seat 13 through the threaded hole.

[0030] In this embodiment, when it is necessary to control the lifting of the connecting ring, the second motor is started, and the second motor is used to drive the screw rod 12 to rotate. The screw rod 12 is threadedly connected with the lifting seat 13. Therefore, the lifting seat 13 will rise or fall under the limiting action of the guide rods 11. The lifting seat 13 is rotatably connected with the hollow tube 15. Therefore, when the lifting tube 15 rotates, the lifting seat 13 does not rotate.

[0031] As Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, as a preferred embodiment of the present invention, the shunt assembly includes a plurality of sewage pipes 9, which are fixedly installed on the outer wall of the shunt valve 10. A plurality of telescopic rods 29 are also rotatably installed on the outer wall of the shunt valve 10. The number of telescopic rods 29 is the same as the number of sewage pipes 9. The telescopic end of the telescopic rod 29 is fixedly connected with a slip ring 30, and the slip ring 30 is slidably sleeved on the sewage pipe 9.

[0032] In this embodiment, the sewage is pumped by the sewage pump 6 and enters the shunt valve 10. The sewage is divided into multiple streams by the shunt valve 10 and enters different sewage pipes 9 respectively. During filtration, in order to ensure that all parts of the filter screen 16 can participate in filtration, by telescoping the telescopic rods 29 to different lengths, the sewage is radially distributed on the filter screen 16. Since the filter screen 16 is in a rotating state, the effective filtration area on the filter screen 16 will increase, avoiding the accumulation of sewage in a local area on the filter screen 16.

[0033] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, as a preferred embodiment of the present invention, a partition is provided inside the aggregate box 1. The partition is of an annular structure and is arranged around the rotating mechanism.

[0034] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, as a preferred embodiment of the present invention, sewage pipes are provided on the base 18 and the aggregate box 1, and the sewage pipes are communicated with the sewage outlet 4 provided on the aggregate box 1.

[0035] In this embodiment, by providing the partition, the rotating mechanism is separated from the space for storing floc, so as to facilitate the centralized treatment of floc, and the filtered sewage is discharged from the sewage pipe.

[0036] As Figure 1 As shown, as a preferred embodiment of the present invention, a door panel 2 is provided on the aggregate box 1. The door panel 2 is connected to the aggregate box 1 through a hinge 3, and a locking assembly is further provided between the door panel 2 and the aggregate box 1. The locking assembly is used to limit the relative rotation of the door panel 2 with respect to the aggregate box 1.

[0037] In this embodiment, the locking assembly can be a magnetic attraction structure, that is, magnetic blocks are provided on both the door panel 2 and the aggregate box 1, and the two are adsorbed by magnetic force. When opening the door is required, the door panel 2 can be pulled open, and then the floc can be cleaned.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
