DETAILED DESCRIPTION

[0048] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0049] Example 1

[0050] In the prior art, in order to simplify the treatment process and reduce the operating time, it is often necessary to carry out multiple steps such as aeration and flocculation in one pool. Different steps require different equipment, and the existing treatment equipment cannot be linked, so the utilization rate of the treatment equipment is low, resulting in a waste of resources.

[0051] Based on this, the present invention provides a device for recycling textile printing and dyeing wastewater, such as Figure 1-5 As shown, including:

[0052] Feed tank 1, wastewater enters feed tank 1 and gathers;

[0053] The treatment tank 2 is arranged below the feed tank 1 and is connected with the feed tank 1. In this embodiment, the treatment tank 2 is located at the lower right of the feed tank 1, and the wastewater is collected in the feed tank 1 and then enters the treatment tank 2 for treatment.

[0054] The barrier net 3 is arranged at one end of the feed tank 1 close to the treatment tank 2. In this embodiment, the barrier net 3 is used to block the solid impurities in the wastewater from passing through, so as to ensure the normal progress of subsequent wastewater treatment work.

[0055] The driving assembly is used to clean the barrier net 3 and stir and spray the wastewater in the treatment pool 2 to achieve flocculation, mixing and aeration. The driving assembly includes a reciprocating part 41, a spraying part 42, a stirring part 43 and a driving motor 44.

[0056] The reciprocating portion 41 is disposed at one side of the feed pool 1 and abuts against the barrier net 3; specifically, the reciprocating portion 41 corresponds to the position of the barrier net 3.

[0057] The spraying part 42 is arranged above the treatment pool 2 and is transmission-connected with the reciprocating part 41;

[0058] The stirring part 43 is arranged below the spraying part 42 and extends into the interior of the treatment tank 2;

[0059] The driving motor 44 is connected to the reciprocating portion 41 .

[0060] The specific working process of this embodiment is:

[0061] The driving motor 44 is started, and the reciprocating part 41 is used to clean the barrier net 3 to prevent the barrier net 3 from being blocked and causing the wastewater to be unable to enter the treatment pool 2. The reciprocating part 41 transmits power to the spraying part 42 to drive the spraying part 42 to rotate to achieve uniform spraying to achieve sufficient aeration.

[0062] At the same time, the stirring part 43 and the spraying part 42 move synchronously to stir the wastewater in the treatment tank 2, thereby accelerating the full mixing of the flocculant and the wastewater and accelerating the completion of flocculation.

[0063] In order to further ensure that the wastewater enters the feed tank 1 and flows stably to the side of the treatment tank 2, it is configured as follows: the bottom of the feed tank 1 is inclined and the lower end of the inclination is close to the side of the treatment tank 2. Through the above configuration, the wastewater can flow stably to the right, avoiding the accumulation of wastewater in the feed tank 1.

[0064] In order to slow down the rate at which wastewater enters the treatment pool 2 and reduce the pollution caused by wastewater splashing, it is configured that: the side of the treatment pool 2 close to the feed pool 1 is concave and tilted inward to form a guide surface. Specifically, the guide surface is a smooth curved surface with a certain slope. After the wastewater is filtered by the barrier net 3, the wastewater flows downward and slowly flows down with the guide surface to avoid wastewater splashing.

[0065] Furthermore, a plurality of buffer convex strips arranged in an alternating manner are provided on the guide surface to further reduce the water flow velocity, thereby avoiding splashing of water due to excessively fast flow.

[0066] Example 2

[0067] After the wastewater enters the feed tank 1 and flows to the barrier net 3, solid impurities (such as cotton fibers and textile scraps) in the wastewater are blocked and accumulated at the barrier net 3, causing blockage.

[0068] Based on the above problems, the present invention provides another embodiment, such as Figure 1 and Figure 4 As shown, the reciprocating portion 41 includes a rotating shaft 411, a driving rod 412, a moving block 413 and a scraper 414.

[0069] The rotating shaft 411 is connected to the output end of the driving motor 44 ; specifically, the driving motor 44 provides power for the rotation of the rotating shaft 411 .

[0070] The driving rod 412 is installed on the rotating shaft 411 ; thus, the driving rod 412 is driven by the rotating shaft 411 and rotates with the rotating shaft 411 as the rotation center.

[0071] The moving block 413 is slidably connected to the top of the blocking net 3, and a sliding hole is provided on the moving block 413 for the driving rod 412 to slide. Specifically, the moving block 413 and the blocking net 3 are slidably connected in the form of: a guide groove is provided on the top of the blocking net 3, and a guide block slidably connected to the guide groove is provided at the bottom of the moving block 413, thereby limiting the sliding of the moving block 413. In addition, when the driving rod 412 rotates, the driving rod 412 slides in the sliding hole to drive the moving block 413 to move back and forth.

[0072] The scraper 414 is connected to the bottom of the moving block 413 and abuts against the blocking net 3. Specifically, the reciprocating movement of the moving block 413 drives the scraper 414 to clean the blocking net 3 back and forth, so as to prevent cotton fibers, textile scraps, etc. from blocking the blocking net 3 and affecting the passage of wastewater. In addition, the number of scrapers 414 can be set to be more than one, so as to better and more comprehensively scrape the solid impurities on the blocking net 3.

[0073] The working process of the reciprocating unit 41 in this embodiment is as follows:

[0074] The driving motor 44 is started, the rotating shaft 411 starts to rotate, and then the driving rod 412 starts to rotate together with the rotating shaft 411. The driving rod 412 slides in the sliding hole, and then drives the moving block 413 and the scraper 414 to do a reciprocating motion.

[0075] Furthermore, when the waste in the wastewater accumulates to a certain extent, the scraper 414 will scrape off the impurities on the blocking net and will soon cause blockage again under the impact of the wastewater. At this time, the treatment effect of the scraper 414 will deteriorate. Based on this, Figure 4 and Figure 5As shown, the moving block 413 is rotatably arranged with dispersion rods 9 located on both sides of the scraper 414. Specifically, the dispersion rod 9 includes a rotating rod and a dispersion blade. The rotating rod rotates. After the scraper 414 is processed, the dispersion blade can stir and disperse the impurities in the wastewater flowing to the front side of the barrier net 3 to a certain extent, so that the solid impurities can adhere to the barrier net 3 more slowly, thereby improving the treatment effect through the cooperation of the scraper 414 and the dispersion rod 9. There are many forms of rotation of the dispersion rod 9. The first is driven by a servo motor. The servo motor is connected to one of the dispersion rods 9. The two dispersion rods 9 are connected by a conveyor belt transmission, and finally the two dispersion rods 9 rotate. The second is driven by the impact force of the wastewater. The bottom of the two dispersion rods 9 is provided with a driving blade, that is, when the wastewater impacts, the driving blade rotates to drive the rotation of the rotating rod, and finally the dispersion effect is achieved. It can be known that either of the two rotation modes can be used, that is, when the impact force of the wastewater is large, the second rotation form is used and can save resources; in other cases such as when the impact force is small, the dispersion rod 9 can be rotated by a servo motor.

[0076] Example 3

[0077] In order to ensure that the treatment pool 2 is fully aerated and the aeration is uniform, the present embodiment pumps the water in the treatment pool 2 to the top of the treatment pool 2 for spraying, so that the water in the treatment pool 2 is more fully mixed with the air, thereby improving the aeration efficiency.

[0078] Specifically, Figure 1 and Figure 2 As shown, the spraying part 42 includes a water tank 421, a liquid inlet cylinder 422, a liquid distribution pipe 423 and a vertical pipe 424.

[0079] The water tank 421 is fixedly supported above the treatment pool 2 by a fixing frame, and the fixing frame is arranged on one side of the treatment pool 2; specifically, the treatment pool 2 is connected to a water pump (not shown in the figure), and a filter screen is arranged at the connection point between the water pump and the treatment pool 2, and then the water pump is connected to the water tank 421, so that the water pump draws the wastewater filtered by the filter screen in the treatment pool 2 into the water tank 421.

[0080] The liquid inlet cylinder 422 is rotatably disposed at the bottom of the water tank 421 and is in communication with the water tank 421. The liquid inlet cylinder 422 is in transmission connection with the rotating shaft 411.

[0081] There are multiple dispensing tubes 423 and all are connected to the liquid inlet cylinder 422; specifically, the dispensing tubes 423 are L-shaped, and the dispensing tubes 423 rotate with the liquid inlet cylinder 422. In this embodiment, the number of the dispensing tubes 423 is three, and it is known that the number of the dispensing tubes 423 is not limited, and can also be two, four or five.

[0082] There are multiple vertical tubes 424, and the multiple vertical tubes 424 are respectively connected to and communicated with the multiple liquid dispensing tubes 423. Specifically, the number of vertical tubes 424 corresponds to the number of liquid dispensing tubes 423 and the number can be rotated on the liquid dispensing tubes 423.

[0083] In this embodiment, an aeration pipe is provided in the treatment pool 2, and air moves from the bottom of the pool to the surface of the pool; at the same time, the water in the water tank 421 enters the liquid inlet cylinder 422, and the liquid inlet cylinder 422 is diverted to three liquid distribution pipes 423. The wastewater in the three liquid distribution pipes 423 is transmitted to their respective vertical pipes 424 for spraying.

[0084] Further optimization, each of the vertical pipe 424 and the liquid inlet cylinder 422 is circumferentially arranged with a plurality of nozzles 425, the number of the nozzles 425 can be 3-5 and all are connected to the corresponding vertical pipe 424 or liquid inlet cylinder 422. Specifically, the plurality of nozzles 425 are all facing the treatment pool 2.

[0085] Specifically, the working process of the spraying part 42 is as follows:

[0086] The water in the water tank 421 enters the liquid inlet cylinder 422 , part of the water in the liquid inlet cylinder 422 is sprayed out through the bottom nozzle 425 , and the other part is divided into three liquid distribution pipes 423 , and then transmitted to the respective vertical pipes 424 , and finally sprayed out from the nozzle 425 on the vertical pipe 424 .

[0087] Example 4

[0088] In addition, when performing coagulation treatment, it is often necessary to add a coagulant and set up a stirring unit 43 to fully mix the wastewater and the coagulant.

[0089] Based on Example 3, the present invention provides another embodiment, such as Figure 1 and Figure 6 As shown, the stirring part 43 includes a driving wheel 431, a driven wheel 432, a fixing ring 433 and a stirring rod 434.

[0090] The driving wheel 431 is sleeved on the liquid inlet cylinder 422;

[0091] There are multiple driven wheels 432, which are respectively sleeved on multiple vertical tubes 424 and meshed with the driving wheel 431; specifically, the number of driven wheels 432 corresponds to the number of vertical tubes 424. In this embodiment, there are three driven wheels 432.

[0092] The fixing ring 433 is fixedly mounted on the bottom of the water tank 421, and a rack meshing with the plurality of driven wheels 432 is disposed on the inner ring side of the fixing ring 433;

[0093] There are multiple stirring rods 434 , and the multiple stirring rods 434 are respectively connected to the multiple vertical tubes 424 and the bottom of the liquid inlet cylinder 422 , and each of the stirring rods 434 is circumferentially arranged with multiple stirring blades 435 .

[0094] Specifically, the specific working process of this embodiment is:

[0095] In embodiment 3, liquid feed cylinder 422 is connected with transmission shaft transmission, and specifically, transmission form can be: by belt transmission or sprocket chain transmission etc.Thereby liquid feed cylinder 422 starts to rotate, drives driving wheel 431 to rotate thereupon, finally drives three driven wheels 432 to rotate between fixed ring 433 and driving wheel 431, and then driven wheel 432 drives vertical pipe 424 to rotate.Vertical pipe 424 rotation form is: when vertical pipe 424 rotates, circumferential rotation is carried out with liquid feed cylinder 422 as center.This rotation form is similar to planetary gear rotation.Finally, stirring rod 434 corresponding to multiple vertical pipes 424 and liquid feed cylinder 422 is connected to each other and stirs in treatment tank 2 to fully mix coagulant and waste water.

[0096] It can be known that, while stirring, air and wastewater are fully combined for aeration. In addition, the rotation of the liquid inlet cylinder 422 and the three vertical pipes 424 drives the corresponding connected nozzles 425 to rotate and move. Compared with the existing fixed spraying, this embodiment sprays while moving and rotating, which can further improve the aeration efficiency.

[0097] Example 5

[0098] When a certain amount of solid waste is accumulated on the barrier net 3, the waste needs to be cleaned up to ensure the normal subsequent wastewater treatment.

[0099] Based on this, the present invention provides another embodiment, such as Figure 1 and Figure 3 As shown, a waste collection box 5 is provided at the bottom of the feed pool 1, and a feed port 6 is provided at the top of the waste collection box 5. Specifically, after the feed port 6 is opened, solid impurities enter the waste collection box 5 under the action of gravity and are collected.

[0100] Further, the waste collection box 5 is rotatably provided with a baffle 7 for opening or closing the feed port 6. Specifically, a hydraulic rod 8 is rotatably provided on one side of the waste collection box 5, and the telescopic end of the hydraulic rod 8 is rotatably connected to the bottom of the baffle 7.

[0101] When closing, the hydraulic rod 8 extends, driving the baffle 7 to rotate clockwise until the baffle 7 reaches the horizontal position to completely block the feed inlet 6.

[0102] When opening, the hydraulic rod 8 is retracted, driving the baffle 7 to rotate counterclockwise and finally opening the feed inlet 6, so that solid impurities can stably enter the waste collection box 5.

[0103] The specific working process of the present invention is:

[0104] By providing a driving motor 44, the three processes of clearing the filter from blockage, fully aerating the treatment tank 2 and stirring the treatment tank 2 can be carried out in a linked manner.

[0105] Specifically, the driving motor 44 is started, the rotating shaft 411 starts to rotate, and then the driving rod 412 starts to rotate together with the rotating shaft 411, and the driving rod 412 slides in the sliding hole, thereby driving the moving block 413 and the scraper 414 to make a reciprocating motion.

[0106] In addition, the liquid inlet cylinder 422 is connected to the transmission shaft, so that the liquid inlet cylinder 422 starts to rotate, which drives the driving wheel 431 to rotate, and finally drives the three driven wheels 432 to rotate between the fixed ring 433 and the driving wheel 431, and then the driven wheel 432 drives the vertical pipe 424 to rotate. Finally, the stirring rod 434 correspondingly connected to the multiple vertical pipes 424 and the liquid inlet cylinder 422 stirs in the treatment tank 2 to fully mix the coagulant and the wastewater.

[0107] The water in the water tank 421 enters the liquid inlet cylinder 422 , part of the water in the liquid inlet cylinder 422 is sprayed out through the bottom nozzle 425 , and the other part is divided into three liquid distribution pipes 423 , and then transmitted to the respective vertical pipes 424 , and finally sprayed out from the nozzle 425 on the vertical pipe 424 .

[0108] Furthermore, while stirring, air and wastewater are fully combined for aeration. In addition, the rotation of the liquid inlet cylinder 422 and the three vertical pipes 424 drives the corresponding connected nozzles 425 to rotate and move.

[0109] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention.
