Detailed implementation manners

[0028] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0029] Example 1, referring to Figures 1 - 5 , which is the first embodiment of the present invention. This embodiment provides a polyester staple fiber waste water treatment device, which includes a neutralization reaction tank 1 for containing untreated waste water and a neutralizing agent, a liquid guide plate 2 provided on the neutralization reaction tank 1 for making the untreated waste water and the neutralizing agent fully mixed by gravity to reduce the corrosiveness of the waste water, a waste water delivery pipe 3 provided on the neutralization reaction tank 1, a delivery pump 4 provided on the waste water delivery pipe 3. The delivery pump 4 is used to cooperate with the waste water delivery pipe 3 to convey the waste water in the neutralization reaction tank 1 so that the neutralized waste water enters the next process, a fiber separation tank 5 provided on the waste water delivery pipe 3 for containing the waste water after acid-base neutralization, a capture unit 6 provided on the fiber separation tank 5 for collecting fiber debris in the neutralized waste water, and a fiber collection unit 7 slidably provided on the capture unit 6 for quickly cleaning the fiber debris collected on the capture unit 6 for convenient recycling.

[0030] In summary, when the waste water enters the neutralization reaction tank 1, at this time, the neutralization reaction tank 1 releases the neutralizing agent. Through the cooperation of the liquid guide plate 2, the waste water is fully mixed with the neutralizing agent during the falling process. By doing so, while ensuring the full mixing reaction of the waste water and the neutralizing agent, it can also avoid the entanglement of fiber debris caused by using stirring equipment such as impellers. At this time, the neutralized waste water is conveyed into the fiber separation tank 5 through the cooperation of the waste water delivery pipe 3 and the delivery pump 4. When the waste water enters the fiber separation tank 5, the fiber debris in the flowing waste water is collected by the capture unit 6. When the device pauses operation, at this time, the fiber collection unit 7 can quickly separate the fiber debris collected by the capture unit 6 from the capture unit 6 for convenient cleaning and recycling. Example 2, referring toFigures 1 - 5 This is the second embodiment of the present invention. Different from the previous embodiment, the pH value of the wastewater is adjusted to reduce the corrosiveness of the wastewater. Further, compared with Embodiment 1, anti-corrosion coatings are provided on both the neutralization reaction tank 1 and the liquid guide plate 2. Multiple groups of liquid guide plates 2 are arranged in the neutralization reaction tank 1. The liquid guide plate 2 is arranged in an inclined state in the neutralization reaction tank 1, and the inclination directions of adjacent two groups of liquid guide plates 2 are opposite. A gap is provided between the bottom of the liquid guide plate 2 and the inner wall of the neutralization reaction tank 1. In this way, through the arrangement of multiple groups of liquid guide plates 2, the flow path of the wastewater in the neutralization reaction tank 1 becomes longer. When the wastewater and the neutralizing agent flow to the bottom of the liquid guide plate 2 and collide with the inner wall of the neutralization reaction tank 1 and the lower liquid guide plate 2, the mixing of the wastewater and the neutralizing agent is driven. When the wastewater and the neutralizing agent flow to the bottom of the neutralization reaction tank 1 through the liquid guide plate 2, the wastewater and the neutralizing agent are completely mixed at this time, and the corrosiveness in the wastewater is neutralized at this time.

[0031] Among them, a wastewater inlet 11 and a neutralizing agent release unit 12 are provided on the neutralization reaction tank 1. The wastewater inlet 11 is located above the uppermost liquid guide plate 2. The wastewater inlet 11 is used to introduce the wastewater to be treated into the neutralization reaction tank 1. The neutralizing agent release unit 12 is used to store the neutralizing agent and send the neutralizing agent into the neutralization reaction tank 1 to be mixed with the wastewater during the operation of the device to neutralize the corrosiveness of the wastewater. The neutralizing agent release unit 12 includes a neutralizing agent storage tank 121 provided on the neutralization reaction tank 1 and a neutralizing agent pipeline 122 provided on the neutralizing agent storage tank 121. One end of the neutralizing agent storage tank 121 penetrates the neutralization reaction tank 1 and communicates with the uppermost liquid guide plate 2. The neutralizing agent storage tank 121 is used to store the neutralizing agent. A pressure pump is provided in the neutralizing agent storage tank 121. The neutralizing agent pipeline 122 is used to cooperate with the neutralizing agent storage tank 121 to send the neutralizing agent into the neutralization reaction tank 1.

[0032] The remaining structures are the same as those in Embodiment 1.

[0033] In summary, when the wastewater inlet 11 sends the wastewater into the neutralization reaction tank 1, at this time, the neutralizing agent pipeline 122 starts to pump the neutralizing agent into the neutralization reaction tank 1 through the neutralizing agent storage tank 121. At this time, the wastewater and the neutralizing agent flow on the liquid guide plate 2. When the wastewater and the neutralizing agent flow to the lower end of the liquid guide plate 2, at this time, the wastewater and the neutralizing agent collide with the inner wall of the neutralization reaction tank 1 and the surface of the lower liquid guide plate 2. At this time, the wastewater and the neutralizing agent are mixed once, and multiple groups of liquid guide plates 2 are used to make the wastewater and the neutralizing agent collide and mix multiple times, so that the neutralizing agent reacts fully with the wastewater and reduces the corrosiveness of the wastewater.

[0034] Embodiment 3, refer to Figures 1 - 9, which is the second embodiment of the present invention. Different from the previous embodiment: fiber debris is collected. Further, compared with Embodiment 1, a secondary wastewater spraying port 51 is provided on the fiber separation tank 5 for cooperating with the wastewater conveying pipe 3 to convey the neutralized wastewater into the fiber separation tank 5. A liquid discharge port 52 is provided at the bottom of the fiber separation tank 5 for discharging the wastewater after collecting the fiber debris to the next process. A sealing door 53 is provided on the fiber separation tank 5 for closing or opening the inner wall space of the fiber separation tank 5 to expose the fiber collection unit 7, facilitating the staff to collect the captured fiber debris. A sealing strip is provided between the sealing door 53 and the fiber separation tank 5 to strengthen the sealing between the sealing door 53 and the fiber separation tank 5 and prevent leakage during the operation of the device; One end of the wastewater conveying pipe 3 is arranged on the secondary wastewater spraying port 51.

[0035] The capture unit 6 includes an upper inclined capture plate 61 arranged in the fiber separation tank 5, a lower inclined capture plate 62 arranged in the fiber separation tank 5, upper inclined capture teeth 63 arranged on the upper inclined capture plate 61, and lower inclined capture teeth 64 arranged on the lower inclined capture plate 62; Multiple groups of capture units 6 are arranged in the fiber separation tank 5. The upper inclined capture plate 61 is used to divert the wastewater entering the fiber separation tank 5, the lower inclined capture plate 62 is used to guide the wastewater, the upper inclined capture teeth 63 are used to capture the fiber debris in the wastewater flowing on the upper inclined capture plate 61, and the lower inclined capture teeth 64 are used to capture the fiber debris in the wastewater flowing on the lower inclined capture plate 62.

[0036] Among them, the overall shape of the outside of the upper inclined capture plate 61 is convex in the middle and lower on both sides, which is used to divert the wastewater to both sides.

[0037] Among them, there are two groups of lower inclined capture plates 62 in a group of capture units 6, which are respectively arranged on both sides of the inner wall of the neutralization reaction tank 1. The two groups of lower inclined capture plates 62 are inclined, and the position of the mutually close ends is lower. The top of the upper inclined capture plate 61 is set as the water inlet of the capture unit 6, and the two groups of lower inclined capture plates 62 are set as the water outlets of the capture unit 6. The water outlet of the upper capture unit 6 is arranged close to the water inlet of the lower capture unit 6; The upper inclined capture teeth 63 and the lower inclined capture teeth 64 have the same structure; When the channel sends the wastewater into the fiber separation tank 5, at this time, the wastewater is first diverted by the upper inclined capture plate 61 and flows to both sides and enters the lower inclined capture plate 62 below. It gathers in the lower inclined capture plate 62 and then enters the upper inclined capture plate 61 below again. This cycle occurs multiple times, so that the wastewater passes through the upper inclined capture teeth 63 multiple times, and the fiber debris in the wastewater is fully intercepted by the upper inclined capture teeth 63.

[0038] Among them, the fiber collection unit 7 includes a sliding plate 71 slidably arranged on the neutralization reaction tank 1 for sliding up and down on the inner wall of the neutralization reaction tank 1, a fiber collection component 72 arranged on the sliding plate 71 for moving up and down along with the movement of the sliding plate 71 to push out the fiber debris collected by the upper inclined capture teeth 63 for convenient cleaning and recycling, and a power component 73 arranged on the sliding plate 71 for driving the sliding plate 71 to move.

[0039] Among them, the fiber collection component 72 includes a collection plate 721 arranged on the upper inclined capture plate 61 and the lower inclined capture plate 62 for moving on the upper inclined capture teeth 63 to push out the fiber debris collected by the upper inclined capture teeth 63 for convenient collection, a connecting column 722 arranged on the collection plate 721 for supporting the collection plate 721, a connecting plate 723 arranged on the connecting column 722 for driving the collection plate 721 to move up and down through the connecting column 722, and a stabilizing spring 724 arranged on the connecting column 722 for making the movement of the connecting plate 723 more stable to prevent shaking, and at the same time making the collection plate 721 closer to the upper inclined capture plate 61 or the lower inclined capture plate 62 when the device is running; The collection plate 721 is provided with a sliding hole 7211 matching the upper inclined capture teeth 63, and the collection plate 721 moves on the upper inclined capture teeth 63 through the sliding hole 7211. When the collection plate 721 moves upward, the fiber debris collected on the upper inclined capture teeth 63 is scraped off. At this time, the fiber debris is concentrated on the collection plate 721. When the upper surface of the collection plate 721 exceeds the upper inclined capture teeth 63, the fiber debris on the collection plate 721 can be quickly scraped off and collected by tools such as a scraper; The connecting column 722 is movably arranged through the upper inclined capture plate 61 or the lower inclined capture plate 62; One end of the stabilizing spring 724 abuts against the bottom of the upper inclined capture plate 61 or the lower inclined capture plate 62. When the connecting plate 723 drives the connecting column 722 to move up and down, the connecting plate 723 and the upper inclined capture plate 61 or the lower inclined capture plate 62 squeeze the stabilizing spring 724 at this time to make the movement of the connecting plate 723 more stable.

[0040] Among them, the power component 73 includes a connecting block 731 arranged on the sliding plate 71 for driving the sliding plate 71 to move up and down, thereby driving the collection plate 721 to move up and down, a threaded rod 732 arranged on the connecting block 731 for rotating to drive the collection plate 721 to move up and down, a servo motor 733 arranged on the threaded rod 732 for generating power to drive the threaded rod 732 to rotate, and a mounting plate 734 arranged on the servo motor 733 for supporting the servo motor 733; The connecting block 731 is provided with an internal thread 7311 matching the threaded rod 732, and the rotation of the threaded rod 732 drives the connecting block 731 to move up and down through the internal thread 7311.

[0041] Among them, the connecting block 731 penetrates through the fiber separation tank 5. A sliding groove 54 is provided on the fiber separation tank 5 to cooperate with the connecting block 731. The connecting block 731 drives the sliding plate 71 to move up and down through the sliding groove 54. A sliding sealing strip is provided between the sliding plate 71 and the inner wall of the neutralization reaction tank 1 to ensure the sealing between the sliding plate 71 and the neutralization reaction tank 1.

[0042] The remaining structures are the same as those in Embodiment 2.

[0043] In summary, when the wastewater enters the fiber separation tank 5 through the secondary wastewater spraying port 51, at this time the wastewater falls on the upper inclined capture plate 61. At this time, the wastewater is diverted to flow to both sides by the upper inclined capture plate 61. The wastewater flows into the lower inclined capture plate 62 and converges to the middle through the diversion of the lower inclined capture plate 62. When the wastewater flows on the upper inclined capture plate 61 and the lower inclined capture plate 62, it will pass through the upper inclined capture teeth 63. The upper inclined capture teeth 63 intercept the fiber debris in the passing wastewater. Through the multiple diversion and aggregation of the upper inclined capture plate 61 and the lower inclined capture plate 62, the upper inclined capture teeth 63 and the lower inclined capture teeth 64 fully intercept the fiber debris in the wastewater. Finally, the wastewater flowing to the bottom enters the next process through the liquid discharge port 52. When the device suspends operation, at this time the sealing door 53 is opened. At this time, the inside of the fiber separation tank 5 is communicated with the outside. At this time, the servo motor 733 is started to drive the threaded rod 732 to rotate. The connecting block 731 is driven to move upward through the internal thread 7311. At this time, the connecting block 731 drives the connecting plate 723 to move upward through the sliding plate 71. At this time, the connecting plate 723 drives the collecting plate 721 to move upward through the connecting column 722. The collecting plate 721 scrapes the fiber debris intercepted on the upper inclined capture teeth 63 and the lower inclined capture teeth 64 through the sliding holes 7211. When the upper surface of the collecting plate 721 exceeds the upper inclined capture teeth 63 and the lower inclined capture teeth 64, at this time the fiber debris on the upper inclined capture teeth 63 is completely scraped off by the collecting plate 721 and remains on the collecting plate 721. At this time, the staff can quickly recycle the fiber debris on the collecting plate 721 through tools such as a scraper. When the staff leaves the inside of the fiber separation tank 5, at this time the servo motor 733 is started to drive the threaded rod 732 to reverse, driving the connecting block 731 to descend, driving the connecting plate 723 to descend, thereby driving the collecting plate 721 to descend until the bottom of the collecting plate 721 abuts against the upper inclined capture plate 61 or the lower inclined capture plate 62 again. At this time, the sealing door 53 is closed.
