Description

Technical Field

[0001] This invention relates to the field of textile wastewater treatment technology, specifically to a high-efficiency filtration and separation treatment device for textile wastewater. Background Technology

[0002] With the rapid development of society, the textile printing and dyeing industry has also made rapid progress. Wastewater generated by the textile printing and dyeing industry generally contains a large amount of solid waste and flocculent matter, such as dissolved and suspended solids. Existing textile wastewater treatment equipment first requires filtering and separating the solid waste and flocculent matter in the wastewater. However, the inventor found that after using the above equipment, the filter screen is easily clogged, inconvenient to replace, and the filtration effect on solid waste and flocculent matter needs improvement. Therefore, to address the above problems, this invention designs a high-efficiency filtration and separation treatment device for textile wastewater. Summary of the Invention

[0003] The purpose of this invention is to provide a high-efficiency filtration and separation treatment device for textile wastewater. By rotating the stirring blades, the textile wastewater in the separation cylinder is rotated, forming a vortex at the center. The solid waste and flocculent matter in the textile wastewater are subjected to forces that curve towards the center of the vortex during the rotation of the wastewater, causing the solid waste and flocculent matter to move to the center of the vortex. Subsequently, the lifting control ring lifts the textile wastewater upward and controls the opening of the water outlet. The textile wastewater separated on the outermost side of the separation cylinder is discharged outward through the water outlet. The primary filtration of solid waste and flocculent matter in the textile wastewater is achieved through rotational separation.

[0004] To address the aforementioned technical problems, the present invention adopts the following technical solution:

[0005] A high-efficiency filtration and separation treatment device for textile wastewater includes a filter box with several filter chambers inside. Each filter chamber contains a separation cylinder and rotating agitators that cooperate with the separation cylinder. The separation cylinder contains textile wastewater and the rotating agitators agitate and rotate the wastewater, causing impurities in the wastewater to gather towards the center of the vortex. The outer wall of the separation cylinder has several discharge holes. A lifting control ring is installed inside the separation cylinder. The lifting control ring lifts the wastewater in the separation cylinder to keep the liquid level of the wastewater at the same height as the uppermost discharge hole in the vertical direction. During the lifting process, the lifting control ring also rotates to keep the discharge hole in communication with the wastewater, allowing the separated wastewater to be discharged outward through the discharge hole.

[0006] As a preferred embodiment, the water outlet holes are arranged in a circumferential array on the outer wall of the separation cylinder, and the opening direction of the water outlet holes on the cylinder wall is inclined downward from the inside out.

[0007] As a preferred embodiment, the upper end of the rotating shaft of the rotating agitator is rotatably mounted on the upper wall of the filter housing, and a rotating gear is fixedly connected to the top end of the rotating shaft of the rotating agitator. A drive motor is also fixedly mounted on one side of the top end of the filter housing, and a drive gear is fixedly connected to the output end of the drive motor. The rotating gear and the drive gear are meshed and connected by a chain.

[0008] As a preferred embodiment, the diameter of the lifting control ring is equal to the diameter of the separation cylinder, and the lifting control ring is provided with an arc-shaped stop block arranged in a circumferential array to cooperate with the water outlet hole.

[0009] As a preferred embodiment, a control chamber is also fixedly connected to the lower part of the filter housing, and a lifting cylinder and a connecting rod pushed by the lifting cylinder are fixedly installed in the control chamber.

[0010] As a preferred embodiment, the lower end of the lifting control ring is also fixedly connected to a rotating lifting shaft, which is slidably and rotatably disposed on the lower wall of the filter box. The lower end of the rotating lifting shaft is rotatably disposed on the connecting rod, and the lower end of the rotating lifting shaft is also provided with a pair of limiting retaining rings that cooperate with the connecting rod.

[0011] As a preferred embodiment, an extension rod is fixedly provided on the rotating lifting shaft and above the limiting ring, and a pulley is rotatably connected to the outer end of the extension rod. A self-rotating guide rail that cooperates with the pulley is also fixedly provided on the lower side of the filter box.

[0012] As a preferred embodiment, the filter housing has a conveying pipe located above the leftmost filter chamber, and the filter housing has a discharge pipe located on the side wall of the rightmost filter chamber.

[0013] As another preferred embodiment, a filter screen is also provided between the filter chambers.

[0014] The beneficial effects of this invention are:

[0015] 1. This invention uses rotating blades to rotate the textile wastewater inside the separation cylinder, causing it to rotate. The rotating textile wastewater forms a vortex at the center. The solid waste and flocculent matter in the textile wastewater experience forces that curve towards the center of the vortex during rotation, causing the solid waste and flocculent matter to be separated and transferred to the center of the vortex. Subsequently, the lifting control ring lifts the textile wastewater upward and controls the opening of the water outlet. The textile wastewater separated on the outermost side of the separation cylinder is discharged outward through the water outlet. Primary filtration of solid waste and flocculent matter in the textile wastewater is achieved through rotational separation.

[0016] 2. The lifting control ring of this invention raises the liquid level of textile wastewater in the separation cylinder and controls the opening of the water outlet to connect with the textile wastewater through lifting and rotation. After the lifting control ring rotates to open the water outlet, the liquid level in the separation cylinder gradually decreases. After the liquid level decreases, the uppermost water outlet separates from the wastewater surface, resulting in a slower and slower discharge rate of the separated wastewater. Therefore, by slowly driving the wastewater in the separation cylinder to rise, the remaining wastewater is kept in constant communication with all water outlets, thereby stabilizing the discharge rate of the separated wastewater.

[0017] 3. The outlet holes of this invention are inclined downwards from the inside to the outside on the wall of the separation cylinder. This is because the resultant force of gravity and inertial centrifugal force on the wastewater during the rotation of the wastewater in the separation cylinder is inclined downwards. Therefore, the outlet holes, which are also inclined downwards, are more conducive to the discharge of wastewater after separation between the inner and outer rings of the separation cylinder.

[0018] In summary, this high-efficiency filtration and separation treatment equipment for textile wastewater has the advantages of ingenious design, simple structure, stable and efficient operation, and is especially suitable for the field of textile wastewater treatment technology.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] Example 1

[0031] Below Figures 1 to 9 As shown, this embodiment of the invention provides a high-efficiency filtration and separation treatment device for textile wastewater, including a filter box 1. The filter box 1 has several filter chambers 2 inside. Each filter chamber 2 has a separation cylinder 3 and a rotating agitator 4 that cooperates with the separation cylinder 3. The separation cylinder 3 is used to contain textile wastewater and the rotating agitator 4 agitates and rotates the textile wastewater, causing impurities in the textile wastewater to gather towards the center of the vortex. The outer wall of the separation cylinder 3 has several discharge holes 301. The separation cylinder 3 has a lifting control ring 5 inside. The lifting control ring 5 lifts the textile wastewater in the separation cylinder 3 so that the liquid level is always at the same height as the uppermost discharge hole 301 in the vertical direction. During the lifting process, the lifting control ring 5 also controls the discharge hole 301 to be in communication with the textile wastewater by rotating, so that the textile wastewater separated on the outside of the vortex is discharged outward through the discharge hole 301.

[0032] Here, the present invention rotates the textile wastewater in the separation cylinder 3 by rotating the stirring blade 4. The rotating wastewater forms a vortex at the center. The solid waste and flocculent matter in the wastewater experience forces that curve towards the center of the vortex during rotation, thus separating and transferring the solid waste and flocculent matter to the center of the vortex (see attached diagram). Figure 8 Then, the lifting control ring 5 lifts the textile wastewater upward and controls the outlet hole 301 to open. The textile wastewater separated on the outermost side of the separation cylinder 3 is discharged outward through the outlet hole 301. The primary filtration of solid waste and flocculent matter in the textile wastewater is achieved through rotational separation.

[0033] See attached document Figure 5 Specifically, the water outlet holes 301 are arranged in a circular array on the outer wall of the separator 3, and the opening direction of the water outlet holes 301 on the wall of the separator 3 is inclined downward from the inside to the outside.

[0034] It should be noted that the opening direction of the water outlet 301 of the present invention is inclined downward from the inside to the outside on the wall of the separation cylinder 3. This is because the resultant force of gravity and inertial centrifugal force on the wastewater during the rotation of the wastewater in the separation cylinder 3 is inclined downward. Therefore, the water outlet 301, which is also inclined downward, is more conducive to the discharge of wastewater after separation between the inner and outer rings of the separation cylinder 3.

[0035] See attached document Figure 2 and attached Figure 4 Specifically, the upper end of the rotating shaft of the rotating blade 4 is rotatably mounted on the upper wall of the filter box 1. The top end of the rotating shaft of the rotating blade 4 is also fixedly connected to a rotating gear 401. A drive motor 402 is also fixedly mounted on one side of the top of the filter box 1. The output end of the drive motor 402 is fixedly connected to a drive gear 403. The rotating gear 401 and the drive gear 403 are meshed and connected by a chain 404. The drive motor 402 drives the drive gear 403 to rotate, and the chain 404, which is meshed and connected, drives the other rotating gears 401 to rotate synchronously, thereby realizing the rotating blade 4 in each separation cylinder 3 to rotate and stir.

[0036] See attached document Figure 3 and attached Figure 6 Specifically, the diameter of the lifting control ring 5 is equal to the diameter of the separation cylinder 3. The lifting control ring 5 is arranged in a circumferential array with arc-shaped blocks 501 that cooperate with the water outlet 301. The arc-shaped blocks 501 are used to block the water outlet 301 and are released from the blocking state by disengaging from the water outlet 301 under the action of the rotation of the lifting control ring 5.

[0037] See attached document Figure 6 Specifically, a control chamber 6 is fixedly connected to the bottom of the filter box 1. A lifting cylinder 601 and a connecting rod 602 pushed by the lifting cylinder 601 are fixedly installed in the control chamber 6. The lifting cylinder 601 pushes the lifting control ring 5 in each separation cylinder 3 to rise synchronously through the connecting rod 602.

[0038] See attached document Figure 7 Specifically, the lower end of the lifting control ring 5 is also fixedly connected to a rotating lifting shaft 502. The rotating lifting shaft 502 is slidably and rotatably mounted on the lower wall of the filter box 1. The lower end of the rotating lifting shaft 502 is rotatably mounted on the connecting rod 602. The lower end of the rotating lifting shaft 502 is also provided with a pair of limiting rings 503 that cooperate with the connecting rod 602. By setting the limiting rings 503, the lifting control ring 5 is limited during the rising process and can rotate at the same time.

[0039] See attached document Figure 7Specifically, an extension rod 504 is fixedly installed on the rotating lifting shaft 502 and above the limiting ring 503. The outer end of the extension rod 504 is rotatably connected to a pulley 505. A self-rotating guide rail 506 that cooperates with the pulley 505 is also fixedly installed on the lower side of the filter box 1. During the process of the lifting control ring 5 rising, the pulley 505 drives the lifting control ring 5 to rotate through the self-rotating guide rail 506.

[0040] It is worth mentioning that the lifting control ring 5 of this invention raises the liquid level of textile wastewater in the separation cylinder 3 and controls the opening of the water outlet 301 to connect with the textile wastewater through lifting and rotation, respectively. After the lifting control ring 5 rotates to open the water outlet 301, the liquid level in the separation cylinder 3 gradually decreases. After the liquid level decreases, the uppermost water outlet 301 separates from the wastewater surface, resulting in a slower and slower discharge rate of the separated wastewater. Therefore, by slowly driving the wastewater in the separation cylinder to rise gradually through the lifting control ring 5, the remaining wastewater is kept in constant communication with all water outlets 301, thereby stabilizing the discharge rate of the separated wastewater (see attached figure). Figure 9 ).

[0041] See attached document Figure 1 Specifically, the filter box 1 has a conveying pipe 101 above the leftmost filter chamber 2, and the filter box 1 has a discharge pipe 102 on the side wall of the rightmost filter chamber. The conveying pipe 101 is used to convey unfiltered textile wastewater, and the discharge pipe 102 is used to discharge the filtered wastewater.

[0042] Example 2

[0043] like Figure 4 As shown, the components that are the same as or corresponding to those in Embodiment 1 are marked with the same reference numerals as those in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is that a filter screen 201 is also provided between the filter chambers 2. The filter screen 201 is used to filter the separated textile wastewater discharged between the separation cylinders 3. A cleaning door is also provided on the rear side of the filter box 1 for each filter chamber 2. Opening the cleaning door can clean the solid waste remaining in the separation cylinder 3 after filtration and separation.

[0044] The working process of this invention is as follows:

[0045] Textile wastewater enters the separation cylinder 3 through the conveying pipe 101. Then, the drive motor 402 starts, driving the rotating agitator 4 to stir the textile wastewater inside the separation cylinder 3. After being stirred, the textile wastewater rotates within the separation cylinder, forming a vortex. The solid waste and flocculent matter in the textile wastewater experience forces that curve towards the center of the vortex during rotation, causing the solid waste and flocculent matter to be separated and transferred to the center of the vortex, thus achieving separation. Subsequently, the lifting cylinder 601 drives the lifting control ring 5 upwards, and during the upward movement, it is driven by the self-rotating guide rail 506. The lifting control ring 5 rotates, and after the lifting control ring 5 rotates, the arc-shaped baffle 501 disengages from the water outlet and is released from the blocking state. At the same time, the remaining liquid level in the lifting separation cylinder 3 is always kept in communication with all the water outlets 301, and the water discharge rate is maintained stably. The separated wastewater in the inner and outer rings of the separation cylinder 3 is discharged out through the water outlets 301 and transferred to the next separation cylinder 3 for repeated filtration and separation. Finally, the wastewater that has undergone multiple separation and filtration is discharged out through the discharge pipe 102 and enters the next aerated biological filter for further filtration treatment.
