This type of wastewater usually contains difficult-to-degrade synthetic fiber organic matter.

[0003] During the biochemical treatment of synthetic fibers, nozzles are required to spray chemicals into the sedimentation tank. The nozzles add chemicals such as polyaluminum chloride (PAC) and polyacrylamide (PAM) to remove fiber debris and some colloidal organic matter, reduce subsequent biochemical loads, and assist in the sedimentation of some impurities in the sedimentation tank. Afterwards, the overflowing sewage passes through the aeration tank, where microorganisms decompose the synthetic fiber organic matter into methane and carbon dioxide, forming granular sludge at the bottom of the tank.

[0004] However, in the existing technology, the reagent is injected into the sedimentation tank through a nozzle. The water flow in the tank is slow, which easily leads to uneven mixing of the reagent, affecting the initial treatment effect of the sedimentation tank. In addition, the reagent is prone to accumulation and agglomeration at the nozzle port. Long-term accumulation at the port affects the normal spraying of the reagent. Therefore, a synthetic fiber biochemical treatment nozzle and treatment process are proposed. Summary of the Invention

DETAILED DESCRIPTION

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0020] like Figures 1-9 The synthetic fiber biochemical treatment nozzle shown in the figure includes a nozzle 1, one end of the nozzle 1 is provided with a liquid injection port 35, the lower surface of the nozzle 1 is provided with a gathering section 3, the lower surface of the gathering section 3 is slidably inserted with a plurality of insertion frames 4 through an elastic mechanism, the outer surface of the nozzle 1 is slidably sleeved with a sleeve frame 8 through a transverse mechanism, the two sides of the lower surface of the sleeve frame 8 are respectively fixedly connected with scrapers 27, the upper surface of the sleeve frame 8 is connected to a moving rod 14 through a distance adjustment mechanism, the front end of the lower surface of the moving rod 14 is fixedly connected with a connecting column 21, the lower end of the connecting column 21 is fixedly connected with a guide block 23, the front surface of the guide block 23 is provided with an inclined surface 24, the rear surface of the guide block 23 is provided with a rear curved surface 26, the upper surface of the guide block 23 is provided with a top inclined surface 25, the lower surface of the guide block 23 is slidably provided with a water channel 32, and the two sides of the water channel 32 are respectively provided with a panel 33, and a moving mechanism is provided between the two ends of the nozzle 1 and the panel 33; The water flows through the front end of the guide block 23 and is guided and dispersed by the inclined surface 24 . The water flows above along the surface of the top inclined surface 25 , forming a water curtain behind the guide block 23 .

[0021] like Figure 2 、 Figure 3 、 Figure 4As shown, the elastic mechanism includes a snap-in plate 6 fixedly connected to the front surface of the insertion frame 4. A slot 5 is defined on the inner surface of the retracted section 3, and the snap-in plate 6 slides into the inner side of the slot 5. A compression spring 7 is fixedly connected to the upper surface of the snap-in plate 6, the upper end of which is fixedly connected to the inner top surface of the slot 5. The lower sides of the insertion frame 4 are each provided with a chamfered edge 28. When the insertion frame 4 is pushed by the scraper 27, it moves upward, and the snap-in plate 6 moves upward inside the slot 5, squeezing the compression spring 7. When the scraper 27 is removed, the snap-in plate 6 moves downward and resets under the elastic force of the compression spring 7.

[0022] like Figure 6 As shown, the pitch adjustment mechanism includes a connecting base 13 fixedly connected to the upper surface of the sleeve frame 8, a moving rod 14 sliding through the inner side of the connecting base 13, a bent plate 17 fixedly connected to the front upper side of the connecting base 13, and a second screw rod 18 rotatably connected to the inner side of the bent plate 17. A second motor 20 is fixedly mounted on the rear surface of the connecting base 13, and the output shaft of the second motor 20 is fixedly connected to the rear end of the second screw rod 18. The upper surface of the moving rod 14 is fixedly connected to the pitch adjustment plate 19, and the second screw rod 18 is threadedly extended through the surface of the pitch adjustment plate 19. When the second motor 20 is running, the second screw rod 18 rotates, thereby causing the pitch adjustment plate 19 to move forward or backward. During this process, the moving rod 14 moves relative to the connecting base 13.

[0023] L-shaped rods 15 are fixedly connected to the front ends of both sides of the movable rod 14, and guide frames 16 are fixedly connected to the front ends of the connecting base 13. The rear ends of the L-shaped rods 15 slide through the inside of the guide frames 16. During the movement of the movable rod 14, the L-shaped rods 15 will slide relative to the guide frames 16, which can effectively improve the stability of the movable rod 14 during movement.

[0024] like Figure 5 As shown, the front surface of the connecting column 21 is provided with a tapered surface 22. The tapered design can prevent the accumulation of impurities on the front surface of the connecting column 21, and can also prevent excessive resistance to the water flow and affect the formation of the water curtain at the rear.

[0025] like Figure 1 、 Figure 2 、 Figure 3 As shown, the transverse movement mechanism includes a first side plate 9 and a second side plate 10, respectively fixedly mounted on both ends of the nozzle 1. A first screw 11 is provided for rotation between the first and second side plates 9, 10. A first motor 12 is fixedly mounted on the side surface of the first side plate 9. The output shaft of the first motor 12 is fixedly connected to one end of the first screw 11, which is threaded through the inner side of the sleeve frame 8. When the first motor 12 is running, the first screw 11 rotates, thereby causing the sleeve frame 8 to move laterally, adjusting the lateral position of the guide block 23.

[0026] like Figure 1 、 Figure 9As shown, the moving mechanism includes a screw slide 29 fixedly connected to one side of a panel 33. The sliding end of the screw slide 29 is fixedly connected to the lower end of the first side panel 9, and the lower surface of the second side panel 10 is slidably engaged with the other panel 33. The screw slide 29 is conventional, and its sliding end can slide in the front-to-back direction, so that the nozzle 1 can move in the front-to-back direction.

[0027] A track plate 31 is fixedly mounted on the lower end of the second side plate 10. A guide rail 30 is slidably connected to the lower surface of the track plate 31. The guide rail 30 is fixedly mounted on the side surface of the enclosure 33. When the nozzle 1 moves in the forward and backward direction, the track plate 31 slides relatively along the surface of the guide rail 30.

[0028] like Figure 2 、 Figure 3 As shown, the upper surface of the nozzle 1 is fixedly connected to a guide bar 2, and the inner top surface of the sleeve frame 8 slides with the upper surface of the guide bar 2. The design of the guide bar 2 further improves the stability of the sleeve frame 8 when sliding.

[0029] A biochemical treatment process for synthetic fibers is also proposed, which is carried out using the above-mentioned nozzle and comprises the following steps: S1, the front end of the water inlet pipe 34 is connected to the sewage pipeline, and the end of the liquid injection port 35 is connected to the medicine supply pipeline; S2. The sewage in the water inlet pipe 34 is dispersed by the guide block 23 to form a water curtain. The medicine sprayed from the ports of the several inserting frames 4 fully contacts the water curtain and is discharged from the rear end of the water channel 32 after mixing. S3. The sewage discharged from the waterway 32 enters the sedimentation tank for sedimentation and overflow, and then enters the aeration tank to degrade the synthetic fiber organic matter under aerobic conditions by aerobic microorganisms.

[0030] The front end of the water inlet pipe 34 is connected to the sewage pipeline, and the port of the liquid injection port 35 is connected to the chemical supply pipeline. The sewage in the water inlet pipe 34 is dispersed through the guide block 23, and the sewage is dispersed through the guidance of the inclined surface 24. The water flow above is guided by the top inclined surface 25 to prevent the sewage from splashing too high and destroying the water curtain formed at the rear. When the water curtain reaches the bottom of the nozzle 1, the chemicals sprayed from the ports of several insertion frames 4 fully contact with the water curtain, and are discharged from the rear end of the water channel 32 after mixing. The sewage discharged from the water channel 32 enters the sedimentation tank for sedimentation overflow, and then enters the aeration tank after overflow. Aerobic microorganisms degrade synthetic fiber organic matter under aerobic conditions, which has the function of assisting in forming a sewage water curtain, so that the mixing of chemicals and sewage is more complete.

[0031] During long-term use, fiber impurities are easily accumulated on both sides of the water curtain, and the impurities adhere to the surface of the water channel 32. At this time, by controlling the operation of the first motor 12, the first screw 11 is rotated, and the sleeve frame 8 is moved horizontally to one side. After the horizontal movement, the nozzle 1 is controlled to move backward by the screw slide 29, that is, the guide block 23 is moved backward. Due to the guiding effect of the rear curved surface 26, the impurities contact the rear curved surface 26 toward the middle of the upper surface close to the water channel 32. Then the guide block 23 is controlled to move forward and reset. After that, the guide block 23 is controlled to move horizontally to the other side, and then moved backward to scrape the impurities. After the guide block 23 moves backward twice to scrape, the impurities accumulated on both sides can be gathered toward the middle. When sewage is put in subsequently, it can be discharged from the rear end of the water channel 32 under the impact of sewage. Therefore, it has the function of quickly cleaning the accumulated fiber impurities.

[0032] During the cleaning of fiber impurities, when the sleeve frame 8 moves horizontally, the scraper 27 will contact the bevel edge 28, thereby pushing the insertion frame 4 upward to ensure that the scraper 27 can fully contact the lower port of the insertion frame 4 when moving horizontally, thereby achieving the purpose of cleaning the port, preventing the problem of drug accumulation at the port, and achieving the function of rapid cleaning.

[0033] By controlling the operation of the second motor 20, the second screw 18 is rotated, and the distance adjustment plate 19 is moved forward or backward, thereby changing the front and rear positions of the guide block 23, ensuring that the water curtain formed by the guide block 23 to disperse the sewage can be located below the nozzle 1, preventing the water curtain below the nozzle 1 from not forming or dispersing.

[0034] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention.
